US senators accused of coronavirus insider trading are a symbol of moral bankruptcy – The Guardian

Theres something deeply disturbing about seeing someone profit from a disaster, and weve already seen a few examples in the present crisis. First it was the guys who bought up over 17,000 bottles of hand sanitizer in the hopes of selling them at a high markup. (After Amazon put a stop to their sales, the pair of hoarders donated the sanitizer.) Now we have reports that multiple US senators may have acted on inside information about the coronavirus pandemic, selling stocks in anticipation of a crash, even as they failed to warn the public about the danger posed by the virus. These allegations, if they are indeed true, show that even in a time of crisis, our elected officials are looking out for themselves rather than the public.

ProPublica reports that North Carolina Republican Richard Burr, who was receiving daily coronavirus briefings as chairman of the Senate Intelligence Committee, sold off a significant percentage of his stocks, unloading between $628,000 and $1.72m of his holdings, a week before the stock market tanked. And while in public he was insisting that the government was capable of handling the virus, to well-connected constituents at the Capitol Hill Club he was warning that the virus was much more aggressive in its transmission than anything that we have seen in recent history. Then there was Georgia Republican Kelly Loeffler, who according to the Daily Beast also sold a substantial amount of stock in the leadup to the crash, as well as buying shares in the teleworking company Citrix. Other senators also sold stock around the same time, though the evidence of insider trading is less clear in the other cases.

Burr, Loeffler, and the others have denied wrongdoing, though have not offered especially convincing alternate explanations for the sales. If they did trade on insider information, what they did was probably illegalunder the Stock Act, which Burr voted against, lawmakers are prohibited from trading on nonpublic information, though the definition of nonpublic is not always clear and Burr says he relied solely on public news reports.

But even if that was true, the fact that Burr had reason to suspect that the disaster would be worse than he was publicly letting on is a deep betrayal of his constituents. He should entirely lose the confidence of the public, because its clear that he chose to make money at a time when he should have been offering Americans the truth. Thats why even figures like Tucker Carlson and Ben Shapiro have been outraged by the alleged behavior, with Carlson saying there is no greater moral crime than choosing yourself over your country at a time of crisis.

Elected officials whose first response to a pandemic is to cash in are indeed monstrous. But its not especially surprising in the Trump Era, when the pathological pursuit of financial self-interest is widely seen as unobjectionable. Burr and Loeffler were just doing what they learned in Economics 101: rationally maximize your returns, regardless of the consequences for other people. Its a little surprising to see Shapiro condemning this behavior instead of defending it as an example of the glorious free market at work. After all, you frequently see defenses of price-gouging among free market types, which is no less sociopathic of a behavior during a time of need. Its strange to see those who are generally fine with those who profit off human misery like, for example, health insurance companies get so worked up about insider trading.

The alleged behavior of Burr and Loeffler is indeed despicable, and there is a reasonable discussion to be had about whether senators ought to own stock in the first place. Can we trust people to make laws neutrally if they are significantly financially invested in the outcome of those laws? But we should also make sure not to over-focus on insider trading and corruption as being whats wrong with our politics. They are one part of what is wrong, to be sure, but more important than self-enrichment is the fact that US senators are allowing people to suffer and die needlessly by failing to push through the measures needed to deal with the coronavirus crisis.

Unethical and selfish behavior becomes especially disgusting in a time of a deadly pandemic, but we must keep our focus on giving people the healthcare and economic relief they will need to get through this. The inadequacy of current measures is a crime in which many elected officials in both parties are complicit, and we should be just as angry at the legislators who kill people through inaction as the few who jumped at the opportunity to make a buck.

Deadline for Compensation from Opioid Bankruptcy Fund in June 2020 – Legal Examiner

According to the United States Drug Enforcement Agency, which tracks the path of every single pain pill sold in the United States, 76 billion oxycodone and hydrocodone pain pills were sold from 2006 through 2012. During this growing drug epidemic manufacturers increased production about 51 percent from 8.4 billion in 2006 to 12.6 billion in 2012.

Now the drug companies that provided the fuel for our nations drug crisis are accused of aggressive marketing of opioids while ignoring or downplaying risk of addiction and overdose and of failing to report suspicious orders and distribution all in the name of profit. Communities were ravaged, families destroyed, and people died. According to the U.S. Centers for Disease Control and Prevention, 702,000 people died in the nation from 1999 to 2017 from a drug overdose, and 68% of those deaths were attributed to opioid overdoses.

During this period, six companies were responsible for distributing the majority of pills: McKesson Corp., Walgreens, Cardinal Health, AmerisourceBergen, CVS and Walmart. The four companies who manufactured the majority of these opioids were SpecGx, a subsidiary of Mallinckrodt; Actavis Pharma; Par Pharmaceutical, a subsidiary of Endo Pharmaceuticals; and Purdue Pharma.

The case against these pharmaceutical companies is simple what responsibility do they bear for helping create, and then profit, this deadly epidemic? I believe that ultimately these companies are responsible. They prioritized profits over human suffering. When dire reports of opioid addiction began to surface, they increased production. When people overdosed and died, they denied responsibility.

If you or a loved one became addicted to opioids that were prescribed by a doctor, such as Vicodin, hydrocodone, Percocet, Oxycontin, oxycodone or others and suffered through rehab, the loss of a job, losing custody of a child, or an ended marriage, we can explore your legal options. If you lost someone you care about died from an overdose, we can offer you a qualified opinion on your potential opioid lawsuit.

Through cases like these, we may be able to help stop the spread of opioid addiction.

If you have suffered from dependence on a prescription opioid call Saunders & Walker for a free confidential consultation about whether you may have a claim for monetary compensation from the bankruptcy fund. Call us at 800-748-7115.

Amazon seeking to purchase 4 Fairway locations after grocerys bankruptcy filing – The Real Deal

Amazon is looking to buy four Fairway Market stores in New York and New Jersey, two months after the grocery chain filed for bankruptcy.

The e-commerce giant is focused on acquiring one store in Pelham, New York, one in Brooklyn and two in New Jersey, according to the New York Post. Although there has been speculation that Amazon would use them as distribution centers, its specific plans for the sites are still unknown.

Fairway filed for Ch. 11 bankruptcy in late January, but Amazon has not expressed interest in buying the entire chain or its brand name.

Amazon bought the upscale grocery store chain Whole Foods in 2017 for $13.4 billion. It also recently launched a cashierless grocery store in Capitol Hill and is developing a grocery store in Woodland Hills, California. [NYP] Eddie Small

Commission charts end to execution and torture in human rights plans – EURACTIV

The European Commission is calling on member states to work together on the world stage to put an end to capital punishment and torture.

The details are included in the executives communication on the EU Action Plan on Human Rights and Democracy for 2020-2024, for which the Commission is seeking the backing of EU governments.

The Commission would like to work towards the worldwide abolition of the death penalty, and in countries where the death penalty still exists, insist on the respect of minimum standards and work towards a moratorium on executions as a first step towards abolition.

In terms of global instances of torture, the EU should strive to eradicate torture globally through prevention, prohibition, accountability and redress for victims, the document states.

Chinas capital punishment record

Currently, more than 60% of the global population reside in countries where capital punishment is legal, including China, the US, and India.

Despite access to official figures being tightly guarded by the Chinese authorities, Beijing is believed to administer more executions than any other nation on earth, according to Amnesty International.

During the EU-China summit last year, the bloc raised concerns with their Chinese counterparts about the detainment of Uighur Muslims in Xinjiang province, and an EU delegation reiterated these concerns during the 42nd United Nations Human Rights Council last September.

However, should member states decide to adopt the Commissions approach on its Human Rights Action Plan, any political pressure imposed directly on China is unlikely to come anytime soon, after the EU-China summit, due to take place at the end of March in Beijing, was postponed. The meeting would have been the first coming together of Chinese Premier Li Keqiang and European Commission and European Council presidents, Ursula von der Leyen and Charles Michel, since they took up their new posts.

A second EU-China summit is still slated to take place in Leipzig in September, under the Presidency of the German Council, with Chinas President Xi Jinping meeting all 27 EU leaders.

Human Rights Action Plan

Elsewhere in the EUs action plan, the role of technology and its proximity to human rights abuses was highlighted, with the Commission stating that certain applications can support abusive, unlawful restrictions on movement and speech.

Social media platforms are used to channel targeted disinformation and hate speech that often violate privacy and undermine democracy and human rights, the communication continued.

In this context, recently the European Court of Auditors launched a probe into the blocs attempts to stifle fake news that can cause public harm.

The investigation will focus on the robustness of the 2018 Action plan on disinformation, in addition to whether the EUs code of practice against disinformation has brought tangible improvements to the state of fake news across the bloc.

The code is a self-regulatory voluntary framework signed by platforms including Facebook, Google and Twitter, which obliges them to take measures to control the surge of disinformation online.

Having been put in place ahead of the 2019 European elections, the code received criticism from certain EU Commissioners, with the former Security Commissioner Julian King describingthe initial compliance reports produced by the platforms as patchy, opaque and self-selecting.

In the digital arena, the human rights action plan also brings into question the use of certain Artificial Intelligence applications, saying that they can carry a risk of increased monitoring, control and repression.

In some countries, mass surveillance of citizens is a reality. Data and algorithms can be used to discriminate, knowingly or unknowingly, against individuals and groups, reinforcing societal prejudices.

However, concerns have also been raised about the EUs funding of questionable AI applications on the bloc, as part of the EUs long-term research and development funding mechanism, Horizon 2020.

These include projects such as the iBorderCTRL technology which detects lying through the reading of micro-expressions, and the SEWA initiative a technology will the capacity to read nuances in human facial, vocal and verbal behaviour.

The Orb Abolition Of The Royal Familia – musicOMH.com

(Cooking Vinyl) UK release date: 27 March 2020

Alex Paterson and his merry band are back with a new record, this time with a vaguely colonial theme. The album is ostensibly about the British royal familys involvement in the opium trade, although this is not something one would pick up on by actually listening to it.

The whole sonic approach on Abolition Of The Royal Familia is at once a lot more coherent than The Orbs previous record, the transitions between different genres and moods more methodical and well-paced.

The album opens with Daze (Missing & Messed Up Mix), which is reminiscent of DJ Koze with its laidback disco groove, before picking up the pace and heading for house territory. Hawk Kings (Oseberg Buddhas Buttonhole) is the best track in this first section: dramatic strings trilling on top of an incessant bassline, a snaking melody lurking underneath and the titular Stephen Hawking quotes bookending the song.

The second section is ambient, Pervitin (Empire Culling & The Hemlock Stone Version) dominated by orchestral swells and a French monologue while Afros, Afghans And Angels (Helgo Treasure Chest) makes its mark with Vangelis-style synth work.

As the record moves from this to reggae, then to drum n bass the dreamy vibe of The Queen Of Hearts (Princess Of Clubs Mix) is a particular highlight then back to ambient for its final two tracks, the sound design remains inventive and the journey, while long at 78 minutes, is enthralling and a lot of fun.

Slave Till U Die No Matter What U Buy (Lanse Aux Meadows Mix) brings the record to a close, and while the soundscape is blissful enough with its vapour trail chords, the spoken word sample hits harder than was perhaps intended: stay in your homes no more than two people may gather anywhere without permission.

ARIES (March 21-April 19)Your oracle comes from Aries poet Octavio Paz: The path the ancestors cleared is overgrown, unused. The other path, smooth and broad, is crowded with travelers. It goes nowhere. Theres a third path: mine. Before me, no one. Behind me, no one. Alone, I find my way. APRIL FOOL! Although the passage by Octavio Paz is mostly accurate for your destiny during the rest of 2020, its off-kilter in one way: Its too ponderously serious and melodramatic. You should find a way to carry out its advice with meditative grace and effervescent calm.

TAURUS (April 20-May 20)A century ago, fiery writer Maxim Gorky and hard-ass Taurus politician Vladimir Lenin were listening to a Beethoven sonata together. I cant listen to music too often, Lenin told his companion. It affects your nerves, makes you want to say stupid, nice things. This is crucial advice for you to heed in the coming weeks, Taurus. You need to be as smart and tough as possible, so dont you dare listen to music. APRIL FOOL! Lenin was half-mistaken, and I half-lied. The fact is, music makes you smarter and nicer, and those will be key assets for you to cultivate in the coming weeks. So yes, do listen to a lot of music.

GEMINI (May 21-June 20)By the time he was 55 years old, Gemini author Thomas Hardy had written 18 novels and many poems. His stuff was good enough to win him two separate nominations for a Nobel Prize in Literature. But during the last 32+ years of his life, he never wrote another novel. According to one theory, it was because he was discouraged by the negative reviews he got for his last novel. I suspect you may be at a similar juncture in your life, Gemini. Maybe its time to give up on a beloved activity that hasnt garnered the level of success youd hoped for. APRIL FOOL! The truth is, it is most definitely NOT time to lose hope and faith. Dont be like Hardy. Rededicate yourself to your passionate quests.

CANCER (June 21-July 22)Cancerian theologian John Wesley (17031791) was a Christian who embodied the liberal values that Christ actually taught. He advocated for the abolition of slavery, prison reform, the ordination of women priests, and a vegetarian diet. He gave away a lot of his money and administered many charities. To accomplish his lifes work, he traveled 250,000 miles on horseback and preached 40,000 sermons. Lets make him your role model for the coming weeks. Be inspired by his life as you vividly express your care and compassion. APRIL FOOL! I lied a little bit. Although most of what I just recommended is a good idea, the part about traveling long distances, either on horseback or by other means, is not.

LEO (July 23-Aug. 22)The neurotic but talented French novelist Marcel Proust observed, Everything vital in the world comes from neurotics. They alone have founded religions and composed our masterpieces. With that in mind, and in accordance with current astrological omens, I urge you to cultivate your own neurotic qualities in their extreme forms of expression during the coming weeks. Youre due for some major creative breakthroughs. APRIL FOOL! I was kidding. The fact is, you can generate creative breakthroughs in the coming weeks by being poised and composednot extra neurotic.

VIRGO (Aug. 23-Sept. 22)Virgo author Leon Edel wrote a five-volume biography of renowned author Henry James. In the course of his research, he read 15,000 letters that were written by James. He came to have a profound familiarity with the great man. In accordance with current astrological omens, I recommend that you choose a worthy character about whom you will become equally knowledgeable. APRIL FOOL! I half-lied. Its true that now is an excellent time to deepen your understanding of people you care about. But dont get as obsessed as Edel!

LIBRA (Sept. 23-Oct. 22)About 2,000 years ago, a Roman woman named Sulpicia wrote six short love poemsa total of 40 linesthat are still being analyzed and discussed by literary scholars today. I bring her to your attention because I think that in the next four weeks you, too, could generate a small burst of beauty that will still be appreciated 2,000 years from now. APRIL FOOL! I lied about the small part. The burst of beauty you create in the immediate future could actually be quite large, as well as enduring.

SCORPIO (Oct. 23-Nov. 21)French poet Louis Aragon (18971982) was an influential novelist and a pioneer of surrealistic poetry. Much of his writing had a lyrical quality, and many of his poems were set to music. He also had a belligerent streak. Before the publication of one of his books, he announced that he would thrash any writer who dared to review it in print. Success! There were no critical reviews at all. I recommend his approach to you in the coming weeks. Make it impossible for anyone to criticize you. APRIL FOOL! I lied. I would never suggest that you use violence to accomplish your aims. And besides that, the coming weeks will be a favorable time for you to solicit feedback of all varieties, even the critical kind.

SAGITTARIUS (Nov. 22-Dec. 21)I hesitate to be so blunt, but its my duty to report the facts. According to my reading of the astrological omens, you should have as many orgasms as possible in the next 15 days. You need to tap into the transformative psychological power thats available through monumental eruptions of pleasure and releases of tension. (P.S. Spiritual orgasms will be just as effective as physical orgasms.) APRIL FOOL! What I just said is true, but I left out an important component of your assignment: Be loving and responsible as you pursue your joyous climaxes, never manipulative or exploitative or insensitive.

CAPRICORN (Dec. 22-Jan. 19)Ancient Greek orator Demosthenes was renowned for his skill at delivering powerful, charismatic speeches. While he was still learning his craft, he resorted to extreme measures to improve. For example, there was a time when he shaved just half of his head. It made him ashamed to go out in public, forcing him to spend all his time indoors practicing his speeches. Would you consider a similar strategy right now? APRIL FOOL! I was just messing with you. Its true that the coming weeks will be a good time to minimize your socializing and devote yourself to hard work in behalf of a beloved dream. But shaving half your head isnt the best way to accomplish that.

AQUARIUS (Jan. 20-Feb. 18)The coming weeks will be a favorable time for you to tell as many lies as possible if doing so helps you get what you want. I hereby authorize you to engage in massive deceptions, misrepresentations, and manipulative messages as you seek to impose your will on every flow of events. APRIL FOOL! I lied. In fact, everything I just said was the exact opposite of your actual horoscope, which is as follows: You have a sacred duty to tell more of the truth than you have ever been able to tell before. As you dig deeper to discover more and more of whats essential for you to understand and express, dedicate your efforts to the goal of gliding along with the most beautiful and interesting flow you can find.

PISCES (Feb. 19-March 20)Fifteen minutes before the Big Bang occurred, where was the matter that now constitutes your body and my body? And if, as seems to be true, the Big Bang was the beginning of time, what time was it fifteen minutes earlier? Questions like these are crucial for you to ponder in the next two weeks. APRIL FOOL! I lied. The questions I articulated should in fact be very low priority for you. In the immediate future, youll be wise to be as concrete and specific and pragmatic as you can possibly be. Focus on up-close personal questions that you can actually solve, not abstract, unsolvable riddles.

For the far left, the coronavirus crisis is the perfect time to abolish capitalism and the nuclear family – Hot Air

There has been quite a bit of talk in the past couple of days about when we might get back to normal. The president is hoping that might happen as soon as Easter while others are saying it could be 3-4 months. But some people arent interested in going back to normal. On the contrary, they see the crisis as an inflection point that presents and opportunity for some significant changes to the country.

On the left there are a lot of people who see the crisis as an opportunity to push forward some of the socialist agenda theyve had all along. In some cases, they dont mean European-style social democracy, they want to see an end to capitalism. Heres an example published by NBC yesterday. The author of this is named Paris Marx:

Once COVID-19 abates and people can start leaving their homes, many industries may indeed have collapsed or will be surviving on government support the airline industry being the first. If China and Italy are any indication,carbon emissions and air pollution will have declined. We can choose whether we ramp things back up in a way that continues to threaten our futures and our health by fueling the climate crisis, or we can make the necessary investments and change the regulatory framework to move away from fossil fuels while ensuring that our workers have a future.

When Rep. Alexandria Ocasio-Cortez, D-N.Y., and Sen. Ed Markey, D-Mass., proposed their Green New Deal in February 2019, the most likely implementation of which wouldcost $16.3 trillionover 10 years, it was written off as a green dream by House Speaker Nancy Pelosi, D-Calif., andridiculed by Republicanswho charged it was too expensive and un-American. Yet its policies would provide a job guarantee for being laid off, support for retraining for many workers, and a mass investment program to not only boost the economy, but move it away from fossil fuels.

Is the author suggesting we should not have an aviation industry? I seem to remember that was a big issue when AOC initially released the Green New Deal and a summary that suggested a focus on high speed rail at a scale where air travel stops becoming necessary. Even Sen. Mazie Hirono mocked the idea of replacing air travel with trains saying, That would be pretty hard for Hawaii.

AOCs accidentally leaked agenda, which she backtracked away from at the time, sounds moderate compared to what this author is suggesting. At least AOC wanted to phase out air travel by replacing it with something else. Paris Marx is suggesting that if the industry collapses we just let it burn, even if theres no alternative.

As for the cost of the Green New Deal, that has been a matter of some debate. Initial estimates ranged between $52 and $94 trillion over 10 years. Sanders would later release his own GND plan (under the same name) and claim it would cost $16.3 trillion. However, its important to note that his GND plan was just one of several plans. If you include the cost of his Medicare for All plan, youre right back around $50 trillion over ten years. Thats far beyond even the cost of the current stimulus bill duplicated every year for the next ten years.

Sanders plan also didnt envision a global pandemic which would potentially create a worldwide recession (or worse). Its one thing to promise a government job to out of work people when the economy is running along wish sub-4 percent unemployment. Its quite another to make the math work when unemployment hits 15 percent or higher. The cost of the latter program would be far higher and the ability to cover those costs after taking into account all of the revenue the government will lose because people are out of work will be far less.

Anyway, this isnt even the most extreme proposal being floated during the crisis. Yesterday a site called Open Society published a piece suggesting now is a good time to think about doing away with capitalism and the nuclear family:

Nuclear households, it seems, are where we are all intuitively expected to retreat in order to prevent widespread ill-health. Staying home is what is somehow self-evidently supposed to keep us well. But there are several problems with this, as anyone inclined to think about it critically (even for a moment) might figure out problems one might summarize as the mystification of the couple-form; the romanticisation of kinship; and the sanitization of the fundamentally unsafe space that is private property

In short, the pandemic is no time to forget about family abolition. In the words of feminist theorist and mother Madeline Lane-McKinley; Households are capitalisms pressure cookers. This crisis will see a surge in housework cleaning, cooking, caretaking, but also child abuse, molestation, intimate partner rape, psychological torture, and more. Far from a time to acquiesce to family values ideology, then, the pandemic is an acutely important time to provision, evacuate and generally empower survivors of and refugees from the nuclear household.

And thirdly, even when the private nuclear household poses no direct physical or mental threat to ones person no spouse-battering, no child rape, and no queer-bashing the private family qua mode of social reproduction still, frankly,sucks. It genders, nationalizes and races us. It norms us for productive work. It makes us believe we are individuals. It minimizes costs for capital while maximizing human beings life-making labor (across billions of tiny boxes, each kitted out absurdly with its own kitchen, micro-crche and laundry). It blackmails us into mistaking the only sources of love and care wehavefor the extent ofwhat is possible.

That last link is to an article at a site called Pinko. Heres a sample:

In place of the coercive system of atomized family units, the abolition of the family would generalize what we now call care. Care of mutual love and support; care of the labor of raising children and caring for the ill; care of erotic connection and pleasure; care of aiding each other in fulfilling the vast possibilities of our humanity, expressed in countless ways, including forms of self-expression we now call gender. Care in our capitalist society is a commodified, subjugating, and alienated act, but in it we can see the kernel of a non-alienating interdependence.

Communists like to promise the revolution that sounds like it will be an orgy/art exploration, but the reality is always something closer to Venezuela, i.e. a man-made disaster where millions of nuclear families flee their homes to protect their children.

Even the fringiest of communist ideologues now see a path to what they want in things Sanders and AOC have already introduced in Congress. Were not quite there for the family abolishment people. The full language to propose that as a serious idea hasnt been imported into the mainstream yet, but you can bet they are working on it. AOC has already suggested it makes sense that people no longer want to have children. Little by little theyll make this part of the conversation. The coronavirus is just another crisis the far left doesnt want to go to waste.

The rest is here:

Khwaja Saad, Salman released, demand abolition of NAB – The News International

Khwaja Saad, Salman released, demand abolition of NAB

LAHORE: Veteran politician and central leader of Pakistan Muslim League-N (PML-N) Khwaja Saad Rafiq has demanded abolition of National Accountability Bureau (NAB) immediately to put the country back on development track.

NAB and Pakistan cannot go together, he said while talking to the media on Thursday after getting released from Camp Jail Lahore where he was incarcerated, along with his brother, Khwaja Salman Rafiq, in a NAB case pertaining to Paragon Housing Society scam. Senator Pervaiz Rasheed and other party leaders were also present.

We have suffered 16-month imprisonment in a dark, constricted cell, as the rulers had lodged us there in their pursuit of political victimisation. Nothing was proved against us during that long period of imprisonment, added the former federal minister. Despite severe victimisation, our spirits are high as ever and we are still standing with Nawaz Sharif like before, Saad said.

Saad reminded that the country was dismembered in the past when a minority was imposed on the majority. He regretted that the country was being ruled by incompetent and self-centred people currently. He said his companions and noted politicians were tortured, but declared that we have no desire to take revenge for our political victimisation, as Pakistan cannot afford such victimisation anymore. He said it was up to those people who conspired against their political opponents whether to tell the nation if the country had progressed or regressed during their government. They must tell [the nation] if people of Pakistan have suffered due to their conspiracies or not. National security was compromised and exposed to dangers as a result of stealing of elections, the PML-N leader said.

He said levelling of baseless accusation against political opponents and using state force against them would not work any more. He advised Prime Minister Imran Khan to learn bearing with his opponents. He criticised Pakistan Tehreek-e-Insaf (PTI) government overarrest of Jang Group Chief Executive Officer (CEO) Mir Shakil-ur-Rahman. What was the fault of Mir Shakil-ur-Rahman, asked the PML-N leader adding that his only fault was that his media group criticised all incompetent rulers. He told the premier that an independent media was not his enemy.

He reiterated that the PTI government was not elected. I contested polls against Imran Khan. I won the polls, but the vote recount was not allowed with the connivance of Justice Saqib Nisar. The nation suffered due to his illegal actions, though he is history now, he added. Saad said he wished his party could have changed the black NAB law, adding that there was no political prisoner during the past regimes of PML-N and the Pakistan Peoples Party (PPP). He said political victimisation began with the inception of the PTI government, and political leaders were still languishing in jails. NAB will have to be closed down to let the country progress. Pakistan cannot go together with NAB. A black law designed by a military dictator is still imposed in the so-called democratic regime. It has always been used to crush political opponents, he added.

He said NAB had always been used to suppress fundamental rights of political opponents. He noted that Rana Sanaullah, Shahbaz Sharif, Maryam Nawaz, Hanif Abbasi, Ahad Cheema, Khursheed Shah, Sharjeel Memon, etc., were jailed without establishing charges against them. Ahad Cheema, who worked to develop the city, was still being humiliated in jail, instead of given respect. He noted that honourable judges of Supreme Court had been saying that NAB lacked sincerity and was used against the opponents. He said we dont want the PTI to suffer what the PML-N and PPP leaderships had undergone. We were accused of being terrorists and traitors. Whenever masses will be given a chance, they will stand with us.

The struggle for supremacy of Constitution and democracy will succeed at the end. We will not victimise anyone and level baseless allegations, he added.

Saad said he had only challenged political opponents, and not any institution, when he stated that the PML-N leaders would prove to be lohay ke chanay (iron pellets). He said as to who gave Justice Saqib Nisar the right to humiliate political leaders, and make the nation damn fool in the name of a dam. Movement for judiciarys supremacy was launched by the PML-N and it will reach its logical end.

He said Imran Khan had no desire to save the country from coronavirus, as his intentions were not sincere. Had Imran been sincere, he should have called all opposition parties and asked them to work collectively to protect masses from the virus, the PML-N leader added.

Former railways minister regretted that various train accidents had been taking place. The way of stealing votes in Pakistan must be blocked; otherwise, the nation would continue to suffer and progress will remain a dream, he added.

Saad Rafiq said the rulers had pushed the country to such a disastrous situation that it would take a long time to put the country back on track. He said the PTI leaders could put their names on the PML-N development schemes, but at least they should complete them on time. He expressed confidence that the democracy taken hostage in Pakistan would be liberated soon, and the supporters of the liar prime minister would have to repent. Khwaja Salman Rafiq said his party did not want to do politics on coronavirus, adding that if Taftan border was sealed off timely, situation would have been much different in the country today. He recalled that the PML-N government had eliminated polio in Punjab and federal capital areas, besides controlling the dengue virus. But when dengue resurfaced last year, he felt sorrow over the nullification of Shahbaz governments efforts.

Earlier, when Khwaja brothers were released from camp jail, a large number of party workers, led by Pervaiz Rasheed, Imran Nazir and others welcomed them and took them away in the form of a rally, chanting slogans and showering flower petals on them.

"I can't listen to music too often," Lenin told his companion. "It affects your nerves, makes you want to say stupid, nice things." This is crucial advice for you to heed in the coming weeks, Taurus. You need to be as smart and tough as possible, so don't you dare listen to music. APRIL FOOL! Lenin was half-mistaken, and I half-lied. The fact is, music makes you smarter and nicer, and those will be key assets for you to cultivate in the coming weeks. So yes, do listen to a lot of music.

GEMINI (May 21-June 20): By the time he was 55 years old, Gemini author Thomas Hardy had written 18 novels and many poems. His stuff was good enough to win him two separate nominations for a Nobel Prize in Literature. But during the last 32+ years of his life, he never wrote another novel. According to one theory, it was because he was discouraged by the negative reviews he got for his last novel. I suspect you may be at a similar juncture in your life, Gemini. Maybe it's time to give up on a beloved activity that hasn't garnered the level of success you'd hoped for. APRIL FOOL! The truth is, it is most definitely NOT time to lose hope and faith. Don't be like Hardy. Rededicate yourself to your passionate quests.

CANCER (June 21-July 22): Cancerian theologian John Wesley (17031791) was a Christian who embodied the liberal values that Christ actually taught. He advocated for the abolition of slavery, prison reform, the ordination of women priests, and a vegetarian diet. He gave away a lot of his money and administered many charities. To accomplish his life's work, he traveled 250,000 miles on horseback and preached 40,000 sermons. Let's make him your role model for the coming weeks. Be inspired by his life as you vividly express your care and compassion. APRIL FOOL! I lied a little bit. Although most of what I just recommended is a good idea, the part about traveling long distances, either on horseback or by other means, is not.

LEO (July 23-Aug. 22): The neurotic but talented French novelist Marcel Proust observed, "Everything vital in the world comes from neurotics. They alone have founded religions and composed our masterpieces." With that in mind, and in accordance with current astrological omens, I urge you to cultivate your own neurotic qualities in their extreme forms of expression during the coming weeks. You're due for some major creative breakthroughs. APRIL FOOL! I was kidding. The fact is, you can generate creative breakthroughs in the coming weeks by being poised and composednot extra neurotic.

VIRGO (Aug. 23-Sept. 22): Virgo author Leon Edel wrote a five-volume biography of renowned author Henry James. In the course of his research, he read 15,000 letters that were written by James. He came to have a profound familiarity with the great man. In accordance with current astrological omens, I recommend that you choose a worthy character about whom you will become equally knowledgeable. APRIL FOOL! I half-lied. It's true that now is an excellent time to deepen your understanding of people you care about. But don't get as obsessed as Edel!

LIBRA (Sept. 23-Oct. 22): About 2,000 years ago, a Roman woman named Sulpicia wrote six short love poemsa total of 40 linesthat are still being analyzed and discussed by literary scholars today. I bring her to your attention because I think that in the next four weeks you, too, could generate a small burst of beauty that will still be appreciated 2,000 years from now. APRIL FOOL! I lied about the "small" part. The burst of beauty you create in the immediate future could actually be quite large, as well as enduring.

SCORPIO (Oct. 23-Nov. 21): French poet Louis Aragon (18971982) was an influential novelist and a pioneer of surrealistic poetry. Much of his writing had a lyrical quality, and many of his poems were set to music. He also had a belligerent streak. Before the publication of one of his books, he announced that he would thrash any writer who dared to review it in print. Success! There were no critical reviews at all. I recommend his approach to you in the coming weeks. Make it impossible for anyone to criticize you. APRIL FOOL! I lied. I would never suggest that you use violence to accomplish your aims. And besides that, the coming weeks will be a favorable time for you to solicit feedback of all varieties, even the critical kind.

SAGITTARIUS (Nov. 22-Dec. 21): I hesitate to be so blunt, but it's my duty to report the facts. According to my reading of the astrological omens, you should have as many orgasms as possible in the next 15 days. You need to tap into the transformative psychological power that's available through monumental eruptions of pleasure and releases of tension. (P.S. Spiritual orgasms will be just as effective as physical orgasms.) APRIL FOOL! What I just said is true, but I left out an important component of your assignment: Be loving and responsible as you pursue your joyous climaxes, never manipulative or exploitative or insensitive.

CAPRICORN (Dec. 22-Jan. 19): Ancient Greek orator Demosthenes was renowned for his skill at delivering powerful, charismatic speeches. While he was still learning his craft, he resorted to extreme measures to improve. For example, there was a time when he shaved just half of his head. It made him ashamed to go out in public, forcing him to spend all his time indoors practicing his speeches. Would you consider a similar strategy right now? APRIL FOOL! I was just messing with you. It's true that the coming weeks will be a good time to minimize your socializing and devote yourself to hard work in behalf of a beloved dream. But shaving half your head isn't the best way to accomplish that.

AQUARIUS (Jan. 20-Feb. 18): The coming weeks will be a favorable time for you to tell as many lies as possible if doing so helps you get what you want. I hereby authorize you to engage in massive deceptions, misrepresentations, and manipulative messages as you seek to impose your will on every flow of events. APRIL FOOL! I lied. In fact, everything I just said was the exact opposite of your actual horoscope, which is as follows: You have a sacred duty to tell more of the truth than you have ever been able to tell before. As you dig deeper to discover more and more of what's essential for you to understand and express, dedicate your efforts to the goal of gliding along with the most beautiful and interesting flow you can find.

PISCES (Feb. 19-March 20): Fifteen minutes before the Big Bang occurred, where was the matter that now constitutes your body and my body? And if, as seems to be true, the Big Bang was the beginning of time, what time was it fifteen minutes earlier? Questions like these are crucial for you to ponder in the next two weeks. APRIL FOOL! I lied. The questions I articulated should in fact be very low priority for you. In the immediate future, you'll be wise to be as concrete and specific and pragmatic as you can possibly be. Focus on up-close personal questions that you can actually solve, not abstract, unsolvable riddles.

Tramp for the abolition of restrictions: treatment should not be worse than the problem – The KXAN 36 News

President of the United States Donald trump talked about their assumptions on spread of coronavirus COVID-19. In his opinion, the treatment should not be worse that the problem. About this American leader said during the broadcast on the Fox News channel.

Donald trump believes that many people can die if it is admitted the current situation. According to the President, many want to get back to work.

trump said that previously, they never closed the country, despite severe epidemics of influenza and other diseases. In addition, the American leader said that for many people the stakes are very high they might lose their businesses, lose their jobs.

Donald trump said the country wants to begin the process of returning to a normal situation as soon as possible. If you delay this, the States will lose more people, reports TASS.

the President noted that the authorities want to remove restrictions on the private sector because COVID-19 for the Easter holidays until April 12.

For the last day in the United States from the new virus has killed more than a hundred people. According to the American Johns Hopkins University, currently in the country revealed more than 50 thousand cases of infection with coronavirus. The total number of dead is more than 600 people.

Turkish Columnists Praise Jihad, Martyrdom, And Caliphate: ‘Jihad Is A Valid Ruling Until The Day Of Judgement… If The Muslims Are Unified, [The…

Recent columns in the Turkish press praise jihad and martyrdom and yearn for a caliphate. Burhan Bozgeyik wrote on March 20, 2020: "Jihad is a valid ruling until the Day of Judgement. Jihad will not be abandoned... If the Muslims are unified, [the unbelievers] will all be like dogs at our door." Mustafa Kasadar wrote on February 10: "This ummah has gotten its dignity and honor from jihad and martyrdom." Muzaffer Dereli wrote on March 6: "If we get scared when war and jihad are mentioned, this shows the weakness of our faith."

Mustafa elik wrote on March 11: Democracy, which was imposed as an ideology after the abolition of the caliphate, is a dress of the Greek philosophers that was put on the Muslims... Governing without that which Allah has sent down is a cruelty composed of darkness... If Islam's state governs the world on its own, Allah will lift off of us the despicableness that is thought to be irremovable!" The government-issued sermon for February 28 said: "Our troops obey the call of our prophet to 'make jihad with your hands, your words, and your property.'"

From left to right: Burhan Bozgeyik, Mustafa Kasadar, Muzaffer Dereli, and Mustafa elik.

Following are translated excerpts from the columns and sermon.

"Jihad Is A Valid Ruling Until The Day Of Judgement Jihad Will Not Be Abandoned... If The Muslims Are Unified, [The Unbelievers] Will All Be Like Dogs At Our Door "

In a March 20, 2020 column, Burhan Bozgeyik wrote: "There cannot be Islam without a state. There must be a state, an administrator of all Muslims. This is the truth. Allah's rulings will be dominant in all areas (the sayings and actions of Muhammad are included in these rulings). All Muslims will be brothers, will be united. A Muslim will never draw a weapon on another Muslim. Jihad is a valid ruling until the Day of Judgement. Jihad will not be abandoned. If jihad is abandoned, despicableness will come on its own. The unbelievers will be expelled from every handsbreadth of Muslim land... Let's say it outright: To hell with all of the cruel unbelievers who, in the language of the Quran, are all filth. If the Muslims are unified, they will all be like dogs at our door."[1]

"Our Troops Obey The Call Of Our Prophet To 'Make Jihad With Your Hands, Your Words, And Your Property'"

The February 28 Friday sermon issued by Turkey's Ministry of Religious Affairs read in part: "Our troops are always beside the oppressed against the tyrant. They are at the front for the good of the world, and they take cover in the name of humanity. They are on expedition to run to help those whose rights are taken from them. Our troops stand tall on their feet on the side of truth and against falsehood, having faith in the [Quran 17:81] verse 'And say: "Truth has come and falsehood has collapsed. Verily, falsehood is condemned to collapse.' Our troops run from victory to victory being bound from their hearts to the [Quran 3:139] verse: 'Do not become loose, do not be saddened. If you have faith, you will be superior.' Our troops obey the call of our prophet to 'make jihad with your hands, your words, and your property' and say 'stop' to the brazen raid of the enemy."[2] Turkey's Ministry of Religious Affairs, which prepares the sermons that are given each week at the country's 84,000 mosques, issued this sermon amid fighting in Idlib between the Turkish military and Turkish-backed jihadi factions on one side and the Syrian military on the other.

"This Ummah Has Gotten Its Dignity And Honor From Jihad And Martyrdom"

In a February 10 column, Mustafa Kasadar wrote: "This ummah has gotten its dignity and honor from jihad and martyrdom. This ummah, in the period when it burned and ignited as a whole with the longing for jihad martyrdom, it was the lord of the world. It gave shape and order to the whole world. But whenever it became a nation that was disgusted by death, that forgot the desire for martyrdom, and preferred the worldly life to the hereafter, that is when it fell from the summit and became the plaything of the non-Muslim nations...

"On this occasion we are commemorating with mercy all our martyrs and congratulating all of the civil society organizations, above all the Anadolu Genlik Dernei (Anatolian Youth Assocatian, AGD) who are celebrating February as 'Martyrdom Month' and bringing jihad and martyrdom to the youth agenda once again. We commemorate with mercy and gratitude the jihad leaders 'Izz Al-Din Al-Qassam, Hassan Al-Banna, Abdullah Azzam, Ahmad Yassin, and Necmeddin Erbakan, who are the jihad teachers of our age. The path that will save the ummah from this despicableness today is clear. This path has been tried dozens of times before and every time, with this method, the ummah got up from the place to which it had fallen and reached the summit once again. That path is singular, and it is the construction of an ummah that desires jihad and martyrdom."[3]

"If We Get Scared When War And Jihad Are Mentioned, This Shows The Weakness Of Our Faith"

In a March 6 column, Muzaffer Dereli wrote: "Only hypocrites flee from war when it is necessary. To say: 'Do your worship, leave off jihad' is such a big sign of discord... After permission for war (jihad) came following the hijrah [i.e., migration], the hypocrites feared war with the enemy and they made the entreaty: 'If only this command came a little later.' Today, if we get scared when war and jihad are mentioned, this shows the weakness of our faith. Jihad is making war with [one's] life and property for Allah in the path of Allah. It is working and making effort with [one's] life, property, words, publications, and by other means to spread Allah's supreme name to the universe... When it is necessary, jihad is farz [obligatory] for believers, and the one who is prepared on this path is called a mujahid." Dereli ends his article with two poems about martyrdom and jihad.[4]

Mustafa elik wrote in a March 11 column: "The Rashidun Caliphate[5] is for Muslims a yardstick in government. In the absence of a caliphate, they repeatedly condemn the caliphate. In theology departments they are having doctoral work done to cancel the hadiths of the prophet concerning the caliphate. They are trying to make Muslims the enemy of the order that the prophet recommended. This is a danger as intense as the Day of Judgment. Those who fall into this danger will definitely fall into destruction. They do not know: The caliphate is innate nature,[6] can innate nature be forgotten? Man was created as a caliph. The caliphate entered the picture when man was created. The caliphate is part of the agenda wherever there are people. Because without the caliphate, man's innate nature cannot be satisfied. Those who dirty their minds with ideologies do not know this reality..."

"Democracy... Is A Dress Of The Greek Philosophers That Was Put On The Muslims... Governing Without That Which Allah Has Sent Down Is A Cruelty Composed Of Darkness"

"With the abolition of the caliphate, our world became darker. Never mind the people, [even] the leaves on the trees grew yellow. The poor, the destitute, the orphans, the parentless sought a master to protect and embrace them. In the absence of the caliphate, never mind enemies, brother strafed brother. Those fighting back without a caliphate and without a caliph, benefited the unbelievers more than the Muslims. The enemies of the caliphate took from us the possibility of being governed with our religion. They stole the sun from our eyes and the spring from our noses. In the absence of a caliphate, we experienced winters in the spring of our lives. It was as if we began our lives from the end...

"The abolition of the caliphate is an epic of sorrow. Democracy, which was imposed as an ideology after the abolition of the caliphate, is a dress of the Greek philosophers that was put on the Muslims. The abolition of the caliphate was a wedding of pleasure and joy for those who swallow the fire of ideologies... The ideology that, with the abolition of the caliphate, was put in front of and in place of Islam, is governance without that which Allah has sent down. Governing without that which Allah has sent down is a cruelty composed of darkness... They divided the single ummah into a thousand and one pieces. They made Muslims forget the caliphate, which is the recommendation of the prophet. If Islam's state governs the world on its own, Allah will lift off of us the despicableness that is thought to be irremovable!"[7]

Vladislav Tretiak the abolition of the world Cup: this decision was not a surprise – The KXAN 36 News

the President of Federation of hockey of Russia (FHR) Vladislav Tretyak commented the decision of the International ice hockey Federation (IIHF) to cancel due to the spread of the coronavirus COVID-19 world championship.

Given the unfavorable epidemiological situation in the world, this decision was not a surprise, quotes the words of Tretyak, the press service of the FHR. Termination of a season the teams no reason to postpone our business. Preparing for the next season has already begun.

Also head of the Russian hockey Federation thanked the fans for their support and the players, coaches and all who work with the teams for their hard work. In this case, Tretiak said that the hockey season isnt over.

We hope the Championships of Russia, childrens and youth competitions will be played out. The championship KHL, VHL, MHL must be brought to its logical end to determine the Champions, concluded the triple Olympic champion.

Recall, the outbreak of pneumonia caused by a coronavirus, a new type was recorded in the Chinese city of Wuhan at the end of 2019. To date, the virus has spread to 188 countries and territories. Cases it is already about 308 thousand people, of which 13 thousand died.

Will String Theory Finally Be Put to the Experimental Test? – Scientific American

Many physicists consider string theory our best hope for combining quantum physics and gravity into a unified theory of everything. Yet a contrary opinion is that the concept is practically pseudoscience, because it seems to be nearly impossible to test through experiments. Now some scientists say we may have a way to do exactly that, thanks to a new conjecture that pits string theory against cosmic expansion.

What it comes down to is this question: Does the universe show us all of its quantum secrets, or does it somehow hide those details from our classical eyes? Because if the details can be seen, string theory might not be able to explain them.

One way to rule out the idea is if we can prove that it does not predict an essential feature of the universe. And string theory, it turns out, has a persistent problem describing the most popular account of what went on during the universes earliest moments after the big bang: inflation.

Inflation is the most compelling explanation for why our universe looks the way it does and where the structure came from, says Marilena Loverde, a physicist at Stony Brook University. Inflation explains how, in a sense, we got everything in the universe from nothing. The theory says that the early universe went through a phase of extreme expansion. The process magnified random blips in the quantum vacuum and converted them into the galaxies and other stuff around us.

Theorists have had difficulty, though, showing how, or if, inflation works in string theory. The most promising road to doing sothe so-called KKLT constructiondoes not convince everyone. It depends who you ask, says Suddhasattwa Brahma, a cosmologist at McGill University. It has been a lingering doubt in the back of the minds of many in string theory: Does it really work?

In 2018 a group of string theorists took a series of suggestive results and argued that this difficulty reflected an impossibilitythat perhaps inflation just cannot happen in the theory. This so-called de Sitter swampland conjecture claimed that any version of the concept that could describe de Sitter spacea term for the kind of universe in which we expect inflation to take placewould have some kind of technical flaw that put it in a swampland of rejected theories.

No one has proved the swampland conjecture, and several string theorists still expect that the final form of the theory will have no problem with inflation. But many believe that although the conjecture might not hold up rigidly, something close to it will. Brahma hopes to refine the swampland conjecture to something that would not bar inflation entirely. Maybe there can be inflation, he says. But it has to be a very short period of inflation.

Any limit on inflation would raise the prospect of testing string theory against actual data, but a definite test requires a proof of the conjecture. According to Cumrun Vafa, a physicist at Harvard University and one of the swampland conjectures authors, researchers can start to build a case for the idea if they can connect it to trusted physical laws. There are two levels of it, he says. First is being more confident in the principle. And then theres explaining it.

One approach to building confidence might try to explain what sort of physical rule would limit inflationor, to put the inquiry in a more practical way: How could string theorists hope to persuade cosmologists to reconsider a favored theory?

These kinds of questions led Vafa and his Harvard collaborator Alek Bedroya to seek out a physics-based reason that could justify the swampland conjecture. They found a candidate in a surprising place. It turns out that inflation already has an unsolved problem looking for a solution: theorists have not all agreed on what happens to the very tiniest quantum details when expansion occurs and magnifies the static of the vacuum.

Physicists lack a working theory that describes the world below the level of the so-called Planck length, an extremely minute distance where they expect the quantum side of gravity to appear. Proponents of inflation have typically had to assume that they can one day work those trans-Planckian details into it and that they will not make a big difference to any predictions. But how that step will happen remains an open question.

Vafa and Bedroya have given a simple answer: forget about it. Their new trans-Planckian censorship conjecture asserts that extremely tiny quantum fuzziness should always stay extremely tiny and quantum, despite the magnifying effect of expansion. If this idea is true, it implies limits on the amount of inflation that could happen, because too much of it would mean too much magnification of the trans-Planckian details.

So in a new twist for string theory, researchers can actually look to the sky for some answers. How much inflation is too much for the censorship conjecture? The situation is a bit complicated. Several different models for the actual process of inflation exist, and astrophysicists do not yet have data that confirm any one of them, or the basic idea as a whole, as the correct description of our universe. Researchers have begun working out the limits the new conjecture puts on the many versions of inflation. Some have a built-in way to hide trans-Planckian details, but Loverde says that many of the typical models conflict with the conjecture.

One clear conflict comes from primordial gravitational waves. These waves, which theorists expect arise during the inflationary phase, would have left behind a faint but distinct sign in the cosmic microwave background. So far, they have not been seen, but telescopes are actively looking for them. The censorship conjecture would only allow a ridiculously, unobservably small amount, Loverde saysso small that any sign of these waves would mean the conjecture does not apply to our universe unless theorists can come up with a different explanation for them.

Does this conjecture really amount to a test of string theory? No,it is too early to say that, according to Vafa. The principles are still just conjecturesfor now. The more one connects these principles togethersurprising, unexpected relationsthe more it becomes believable why its true, he says.

Is Machine Learning The Quantum Physics Of Computer Science ? – Forbes

Preamble: Intermittently, I will be introducing some columns which introduce some seemingly outlandish concepts. The purpose is a bit of humor, but also to provoke some thought. Enjoy.

atom orbit abstract

God does not play dice with the universe, Albert Einstein is reported to have said about the field of Quantum Physics. He was referring to the great divide at the time in the physics community between general relativity and quantum physics. General relativity was a theory which beautifully explained a great deal of physical phenomena in a deterministic fashion. Meanwhile, quantum physics grew out of a model which fundamentally had a probabilistic view of the world. Since Einstein made that statement in the mid 1950s, quantum physics has proven to be quite a durable theory, and in fact, it is used in a variety of applications such as semiconductors.

One might imagine a past leader in computer science such as Donald Knuth exclaiming, Algorithms should be deterministic. That is, given any input, the output should be exact and known. Indeed, since its formation, the field of computer science has focused on building elegant deterministic algorithms which have a clear view of the transformation between inputs and outputs. Even in the regime of non-determinism such as parallel processing, the objective of the overall algorithm is to be deterministic. That is, despite the fact that operations can run out-of-order, the outputs are still exact and known. Computer scientists work very hard to make that a reality.

As computer scientists have engaged with the real world, they frequently face very noisy inputs such as sensors or even worse, human beings. Computer algorithms continue to focus on faithfully and precisely translating input noise to output noise. This has given rise to the Junk In Junk Out (JIJO) paradigm. One of the key motivations for pursuing such a structure has been the notion of causality and diagnosability. After all, if the algorithms are noisy, how is one to know the issue is not a bug in the algorithm? Good point.

With machine learning, computer science has transitioned to a model where one trains a machine to build an algorithm, and this machine can then be used to transform inputs to outputs. Since the process of training is dynamic and often ongoing, the data and the algorithm are intertwined in a manner which is not easily unwound. Similar to quantum physics, there is a class of applications where this model seems to work. Recognizing patterns seems to be a good application. This is a key building block for autonomous vehicles, but the results are probabilistic in nature.

In quantum physics, there is an implicit understanding that the answers are often probabilistic Perhaps this is the key insight which can allow us to leverage the power of machine learning techniques and avoid the pitfalls. That is, if the requirements of the algorithm must be exact, perhaps machine learning methods are not appropriate. As an example, if your bank statement was correct with somewhat high probability, this may not be comforting. However, if machine learning algorithms can provide with high probability the instances of potential fraud, the job of a forensic CPA is made quite a bit more productive. Similar analogies exist in the area of autonomous vehicles.

Overall, machine learning seems to define the notion of probabilistic algorithms in computer science in a similar manner as quantum physics. The critical challenge for computing is to find the correct mechanisms to design and validate probabilistic results.

This Is The One Symmetry That The Universe Must Never Violate – Forbes

A setup of the system used by the BaBar collaboration to probe time-reversal symmetry violation... [+] directly. The (4s) particle was created, it decays into two mesons (which can be a B/anti-B combination), and then both of those B and anti-B mesons will decay. If the laws of physics are not time-reversal invariant, the different decays in a specific order will exhibit different properties. This was confirmed in 2012 for the first time: the first direct violation of T-symmetry.

The ultimate goal of physics is to accurately describe, as precisely as possible, exactly how every physical system that can exist in our Universe will behave.The laws of physics need to apply universally: the same rules must work for all particles and fields in all locations at all times.They mustbe good enough so that, no matter what conditions exist or what experiments we perform, our theoretical predictions match the measured outcomes.

The most successful physical theories of all are the quantum field theories that describe each of the fundamental interactions that occur between particles, along with General Relativity, which describes spacetime and gravitation. And yet, there's one fundamental symmetry that applies to not just all of these physical laws, but for all physical phenomena: CPT symmetry. And for nearly 70 years, we've known of the theorem that forbids us from violating it.

There are many letters of the alphabet that exhibit particular symmetries. Note that the capital... [+] letters shown here have one and only one line of symmetry; letters like "I" or "O" have more than one. This 'mirror' symmetry, known as Parity (or P-symmetry), has been verified to hold for all strong, electromagnetic, and gravitational interactions wherever tested. However, the weak interactions offered a possibility of Parity violation. The discovery and confirmation of this was worth the 1957 Nobel Prize in Physics.

For most of us, when we hear the word symmetry, we think about reflecting things in a mirror. Some of the letters of our alphabet exhibit this type of symmetry: "A" and "T" are vertically symmetric, while "B" and "E" are horizontally symmetric. "O" is symmetric about any line that you draw, as well as rotational symmetry: no matter how you rotate it, its appearance is unchanged.

But there are other kinds of symmetry, too. If you have a horizontal line and you shift horizontally, it remains the same horizontal line: that's translational symmetry. If you're inside a train car and the experiments you perform give the same outcome whether the train is at rest or moving quickly down the track, that's a symmetry under boosts (or velocity transformations). Some symmetries always hold under our physical laws, while others are only valid so long as certain conditions are met.

Different frames of reference, including different positions and motions, would see different laws... [+] of physics (and would disagree on reality) if a theory is not relativistically invariant. The fact that we have a symmetry under 'boosts,' or velocity transformations, tells us we have a conserved quantity: linear momentum. The fact that a theory is invariant under any sort of coordinate or velocity transformation is known as Lorentz invariance, and any Lorentz invariant symmetry conserves CPT symmetry. However, C, P, and T (as well as the combinations CP, CT, and PT) may all be violated individually.

If we want to go down to a fundamental level, and consider the smallest indivisible particles that make up everything we know of in our Universe, we'll look at the particles of the Standard Model. Consisting of the fermions (quarks and leptons) and bosons (gluons, photon, W-and-Z bosons, and the Higgs), these comprise all of the particles we know of that make up the matter and radiation we've directly performed experiments on in the Universe.

We can calculate the forces between any particles in any configuration, and determine how they'll move, interact, and evolve over time. We can observe how matter particles behave under the same conditions as antimatter particles, and determine where they're identical and where they're different. We can perform experiments that are the mirror-image counterparts of other experiments, and note the results. All three of these test the validity of various symmetries.

The particles and antiparticles of the Standard Model obey all sorts of conservation laws, but there... [+] are slight differences between the behavior of certain particle/antiparticle pairs that may be hints of the origin of baryogenesis. The quarks and leptons are examples of fermions, while the bosons (bottom row) mediate forces and arise as a consequence of the origin of mass.

In physics, these three fundamental symmetries have names.

Most of the forces and interactions that we're used to obey each of these three symmetries independently. If you threw a ball in the gravitational field of Earth and it made a parabola-like shape, it wouldn't matter if you replaced the particles with antiparticles (C), it wouldn't matter if you reflected your parabola in a mirror or not (P), and it wouldn't matter if you ran the clock forwards or backwards (T), so long as you ignored things like air resistance and any (inelastic) collisions with the ground.

Nature is not symmetric between particles/antiparticles or between mirror images of particles, or... [+] both, combined. Prior to the detection of neutrinos, which clearly violate mirror-symmetries, weakly decaying particles offered the only potential path for identifying P-symmetry violations.

But individual particles don't obey all of these. Some particles are fundamentally different than their antiparticles, violating C-symmetry. Neutrinos are always observed in motion and close to the speed of light. If you point your left thumb in the direction that they move, they always "spin" in the direction that your fingers on your left hand curl in around the neutrino, while antineutrinos are always "right-handed" in the same way.

Some decays violate parity. If you have an unstable particle that spins in one direction and then decays, its decay products can be either aligned or anti-aligned with the spin. If the unstable particle exhibits a preferred directionality to its decay, then the mirror image decay will exhibit the opposite directionality, violating P-symmetry. If you replace the particles in the mirror with antiparticles, you're testing the combination of these two symmetries: CP-symmetry.

A normal meson spins counterclockwise about its North Pole and then decays with an electron being... [+] emitted along the direction of the North Pole. Applying C-symmetry replaces the particles with antiparticles, which means we should have an antimeson spinning counterclockwise about its North Pole decay by emitting a positron in the North direction. Similarly, P-symmetry flips what we see in a mirror. If particles and antiparticles do not behave exactly the same under C, P, or CP symmetries, that symmetry is said to be violated. Thus far, only the weak interaction violates any of the three, but its possible that there are violations in other sectors below our current thresholds.

In the 1950s and 1960s, a series of experiments were performed that tested each of these symmetries and how well they performed under the gravitational, electromagnetic, strong and weak nuclear forces. Perhaps surprisingly, the weak interactions violated C, P, and T symmetries individually, as well as combinations of any two of them (CP, PT, and CT).

But all of the fundamental interactions, every single one, always obeys the combination of all three of these symmetries: CPT symmetry. CPT symmetry says that any physical system made of particles that moves forwards in time will obey the same laws as the identical physical system made of antiparticles, reflected in a mirror, that moves backwards in time. It's an observed, exact symmetry of nature at the fundamental level, and it should hold for all physical phenomena, even ones we have yet to discover.

The most stringest tests of CPT invariance have been performed on meson, lepton, and baryon-like... [+] particles. From these different channels, the CPT symmetry has been shown to be a good symmetry to precisions of better than 1-part-in-10-billion in all of them, with the meson channel reaching precisions of nearly 1 part in 10^18.

On the experimental front, particle physics experiments have been operating for decades to search for violations of CPT symmetry. To significantly better precisions than 1-part-in-a-billion, CPTis observed to be a good symmetry in meson (quark-antiquark), baryon (proton-antiproton), and lepton (electron-positron) systems. Not a single experiment has ever observed an inconsistency with CPT symmetry, and that's a good thing for the Standard Model.

It's also an important consideration from a theoretical perspective, because there's a CPT theorem that demands that this combination of symmetries, applied together, must not be violated. Although it was first proven in 1951 by Julian Schwinger, there are many fascinating consequences that arise because of the fact that CPT symmetry must be conserved in our Universe.

We can imagine that there's a mirror Universe to ours where the same rules apply. If the big red... [+] particle pictured above is a particle with an orientation with its momentum in one direction, and it decays (white indicators) through either the strong, electromagnetic, or weak interactions, producing 'daughter' particles when they do, that is the same as the mirror process of its antiparticle with its momentum reversed (i.e., moving backwards in time). If the mirror reflection under all three (C, P, and T) symmetries behaves the same as the particle in our Universe, then CPT symmetry is conserved.

The first is that our Universe as we know it would be indistinguishable from a specific incarnation of an anti-Universe. If you were to change:

then that anti-Universe would evolve according to exactly the same physical laws as our own Universe.

Another consequence is that if the combination of CPT holds, then every violation of one of them (C, P, or T) must correspond to an equivalent violation of the other two combined (PT, CT, or CP, respectively) in order to conserve the combination of CPT. It's why we knew that T-violation needed to occur in certain systems decades before we were capable of measuring it directly, because CP violation demanded it be so.

In the Standard Model, the neutron's electric dipole moment is predicted to be a factor of ten... [+] billion larger than our observational limits show. The only explanation is that somehow, something beyond the Standard Model is protecting this CP symmetry in the strong interactions. If C is violated, so is PT; if P is violated, so is CT; if T is violated, so is CP.

But the most profound consequence of the CPT theorem is also a very deep connection between relativity and quantum physics: Lorentz invariance. If the CPT symmetry is a good symmetry, then the Lorentz symmetry which states that the laws of physics stay the same for observers in all inertial (non-accelerating) reference frames must also be a good symmetry. If you violate the CPT symmetry, then the Lorentz symmetry is also broken.

Breaking Lorentz symmetry might be fashionable in certain areas of theoretical physics, particularly in certain quantum gravity approaches, but the experimental constraints on this are extraordinarily strong. There have been many experimental searches for violations of Lorentz invariance for over 100 years, and the results are overwhelmingly negative and robust. If the laws of physics are the same for all observers, then CPT must be a good symmetry.

Quantum gravity tries to combine Einsteins General theory of Relativity with quantum mechanics.... [+] Quantum corrections to classical gravity are visualized as loop diagrams, as the one shown here in white. If you extend the Standard Model to include gravity, the symmetry that describes CPT (the Lorentz symmetry) may become only an approximate symmetry, allowing for violations. Thus far, however, no such experimental violations have been observed.

In physics, we have to be willing to challenge our assumptions, and to probe all possibilities, no matter how unlikely they seem. But our default should be that the laws of physics that have stood up to every experimental test, that compose a self-consistent theoretical framework, and that accurately describe our reality, are indeed correct until proven otherwise. In this case, it means that the laws of physics are the same everywhere and for all observers until proven otherwise.

Sometimes, particles behave differently than antiparticles, and that's okay. Sometimes, physical systems behave differently than their mirror-image reflections, and that's also okay. And sometimes, physical systems behave differently depending on whether the clock runs forwards or backwards. But particles moving forwards in time must behave the same as antiparticles reflected in a mirror moving backwards in time; that's a consequence of the CPT theorem. That's the one symmetry, as long as the physical laws that we know of are correct, that must never be broken.

Picking up the quantum technology baton – The Hindu

In the Budget 2020 speech, Finance Minister Nirmala Sitharaman made a welcome announcement for Indian science over the next five years she proposed spending 8,000 crore (~ $1.2 billion) on a National Mission on Quantum Technologies and Applications. This promises to catapult India into the midst of the second quantum revolution, a major scientific effort that is being pursued by the United States, Europe, China and others. In this article we describe the scientific seeds of this mission, the promise of quantum technology and some critical constraints on its success that can be lifted with some imagination on the part of Indian scientific institutions and, crucially, some strategic support from Indian industry and philanthropy.

Quantum mechanics was developed in the early 20th century to describe nature in the small at the scale of atoms and elementary particles. For over a century it has provided the foundations of our understanding of the physical world, including the interaction of light and matter, and led to ubiquitous inventions such as lasers and semiconductor transistors. Despite a century of research, the quantum world still remains mysterious and far removed from our experiences based on everyday life. A second revolution is currently under way with the goal of putting our growing understanding of these mysteries to use by actually controlling nature and harnessing the benefits of the weird and wondrous properties of quantum mechanics. One of the most striking of these is the tremendous computing power of quantum computers, whose actual experimental realisation is one of the great challenges of our times. The announcement by Google, in October 2019, where they claimed to have demonstrated the so-called quantum supremacy, is one of the first steps towards this goal.

Besides computing, exploring the quantum world promises other dramatic applications including the creation of novel materials, enhanced metrology, secure communication, to name just a few. Some of these are already around the corner. For example, China recently demonstrated secure quantum communication links between terrestrial stations and satellites. And computer scientists are working towards deploying schemes for post-quantum cryptography clever schemes by which existing computers can keep communication secure even against quantum computers of the future. Beyond these applications, some of the deepest foundational questions in physics and computer science are being driven by quantum information science. This includes subjects such as quantum gravity and black holes.

Pursuing these challenges will require an unprecedented collaboration between physicists (both experimentalists and theorists), computer scientists, material scientists and engineers. On the experimental front, the challenge lies in harnessing the weird and wonderful properties of quantum superposition and entanglement in a highly controlled manner by building a system composed of carefully designed building blocks called quantum bits or qubits. These qubits tend to be very fragile and lose their quantumness if not controlled properly, and a careful choice of materials, design and engineering is required to get them to work. On the theoretical front lies the challenge of creating the algorithms and applications for quantum computers. These projects will also place new demands on classical control hardware as well as software platforms.

Globally, research in this area is about two decades old, but in India, serious experimental work has been under way for only about five years, and in a handful of locations. What are the constraints on Indian progress in this field? So far we have been plagued by a lack of sufficient resources, high quality manpower, timeliness and flexibility. The new announcement in the Budget would greatly help fix the resource problem but high quality manpower is in global demand. In a fast moving field like this, timeliness is everything delayed funding by even one year is an enormous hit.

A previous programme called Quantum Enabled Science and Technology has just been fully rolled out, more than two years after the call for proposals. Nevertheless, one has to laud the governments announcement of this new mission on a massive scale and on a par with similar programmes announced recently by the United States and Europe. This is indeed unprecedented, and for the most part it is now up to the government, its partner institutions and the scientific community to work out details of the mission and roll it out quickly.

But there are some limits that come from how the government must do business with public funds. Here, private funding, both via industry and philanthropy, can play an outsized role even with much smaller amounts. For example, unrestricted funds that can be used to attract and retain high quality manpower and to build international networks all at short notice can and will make an enormous difference to the success of this enterprise. This is the most effective way (as China and Singapore discovered) to catch up scientifically with the international community, while quickly creating a vibrant intellectual environment to help attract top researchers.

Further, connections with Indian industry from the start would also help quantum technologies become commercialised successfully, allowing Indian industry to benefit from the quantum revolution. We must encourage industrial houses and strategic philanthropists to take an interest and reach out to Indian institutions with an existing presence in this emerging field. As two of us can personally attest, the Tata Institute of Fundamental Research (TIFR), home to Indias first superconducting quantum computing lab, would be delighted to engage.

Planet Earth Report Hidden Quantum Secrets to Earths 100-Million-Light-Year Long Virosphere – The Daily Galaxy –Great Discoveries Channel

Posted on Mar 25, 2020 in Science

Planet Earth Report provides descriptive links to headline news by leading science journalists about the extraordinary discoveries, technology, people, and events changing our knowledge of Planet Earth and the future of the human species.

Earths Virosphere In recent years, scientists have discovered that the world of virus diversity what they sometimes call the virosphere is unimaginably vast, writes Carl Zimmer for the New York Times. They have uncovered hundreds of thousands of new species that have yet to be named. And they suspect that there are millions, perhaps even trillions, of species waiting to be found. Suffice to say that we have only sampled a minuscule fraction of the virosphere, said Edward Holmes of the University of Sydney in Australia. As recently as January 2020 scientists drilled two ice cores from a glacier on the northwestern Tibetan Plateau of China, revealing the existence of 28 never-before-seen virus groups that had been buried there for the past 15,000 year.

Chloroquine The Strange Story Behind the Cure for COVID-19 People are looking for quick solutions of course and this bubbled to the top. We know how to slow the spread of COVID-19 (social distancing, hand washing, etc). But as more people become infected, scientists are moving quickly in search of a cure. But the internet is moving faster, reports Inverse. On Tuesday, March 17, a small, preliminary study on the anti-malarial drug chloroquine (pronounced klaw ruhkwn) as a treatment for COVID-19 published online. While the findings are tentatively promising, the study has been blown into something far bigger, thanks to the power of Elon Musks 32 million followers on Twitter and a Google do

Does the Cosmos Hide its Quantum Secrets? The Answer May Confirm Expansion of the Universe: Many physicists consider string theory our best hope for combining quantum physics and gravity into a unified theory of everything, writes Brendan Z. Foster for Scientific American. Physicists have found a way the theory might limit the cosmic inflation that is thought to have expanded the early universe. Yet a contrary opinion is that the concept is practically pseudoscience, because it seems to be nearly impossible to test through experiments. Now some scientists say we may have a way to do exactly that, thanks to a new conjecture that pits string theory against cosmic expansion. What it comes down to is this question: Does the universe show us all of its quantum secrets, or does it somehow hide those details from our classical eyes? Because if the details can be seen, string theory might not be able to explain them.

Found The edge of the Milky Way Astronomers have long known that the brightest part of the Milky Way, the pancake-shaped disk of stars that houses the sun, is some 120,000 light-years across (SN: 8/1/19). Beyond this stellar disk is a disk of gas. A vast halo of dark matter, presumably full of invisible particles, engulfs both disks and stretches far beyond them (SN: 10/25/16). But because the dark halo emits no light, its diameter is hard to measure. Now, writes Ken Croswell for Science News, Alis Deason, an astrophysicist at Durham University in England, and her colleagues have used nearby galaxies to locate the Milky Ways edge. The precise diameter is 1.9 million light-years, give or take 0.4 million light-years, the team reports February 21 in a paper posted at arXiv.org.

Life on Mercury? a planet with a surface hot enough to melt lead might once have contained ingredients needed for life. Though thats a pretty big might, reports Shannon Hall for the New York Times. The new theory, published last week in the journal Scientific Reports, is based on a particularly muddled feature on the planet orbiting closest to the sun, known as chaotic terrain. Here, the cracked, uneven and jumbled landscape consists of fractured rock, mismatched peaks and collapsed craters.

Has Physics Lost Its Way? – The New York Times

Of course, Lindley reminds us, what constitutes a good scientific theory depends on the scientific context of its time. Surely not, you might think; dont proper scientific theories have to satisfy timeless criteria such as explaining all the phenomena the theories they displace are able to, being able to make testable predictions, being repeatable, and so on? Well, yes, but here is where we get to Lindleys central thesis: Contemporary theoretical physicists seem to have reverted to the idealized philosophy of Platonism. As he puts it, The spirit of Plato is abroad in the world again. Is this true? Platos stance was that it was enough to think about the universe. Surely, we can do better than that today, with our far more powerful mathematical tools and an abundance of empirical data to test our theories against. No physicist I know would say that to understand the laws of nature it is sufficient to think about them.

While its clear that nature obeys mathematical rules, a happy middle ground between Plato and Aristotle would seem to be preferable: to make the math our servant, not our master. After all, mathematics alone cannot entirely explain reality. Without a narrative to superimpose on the math, the equations and formulas lack a connection with physical reality. Lindley makes this point forcefully: I find it essentially impossible to think of physical theories and laws only in mathematical terms. I need the help of a physical picture to make sense of the math. About this, I am in total agreement. The mathematics can be as pretty and aesthetically pleasing as you like, but without a physical correlative, then that is all it is: pretty math.

According to Lindley, something happened in 20th-century theoretical physics that caused some in the field to reach back to the ancient justifications for mathematical elegance as a criterion for knowledge, even truth. In 1963, the great English quantum physicist Paul Dirac famously wrote, It is more important to have beauty in ones equations than to have them fit an experiment. To be fair, Dirac was a rather special individual, since many of his mathematical predictions turned out to be correct, such as the existence of antimatter, which was discovered a few years after his equation predicted it. But other physicists took this view to an extreme. The Hungarian Hermann Weyl went as far as to say, My work always tried to unite the truth with the beautiful, and when I had to choose one or the other, I usually chose the beautiful. Lindley argues that this attitude is prevalent among many researchers working at the forefront of fundamental physics today and asks whether these physicists are even still doing science if their theories do not make testable predictions. After all, if we can never confirm the existence of parallel universes, then isnt it just metaphysics, however aesthetically pleasing it might be?

But Lindley goes further by declaring that much fundamental research, whether in particle physics, cosmology or the quest to unify gravity with quantum mechanics, is based purely on mathematics and should not be regarded as science at all, but, rather, philosophy. And this is where I think he goes too far. Physics has always been an empirical science; just because we dont know how to test our latest fanciful ideas today does not mean we never will.

Partnership between the University of Chicago and Argonne National Laboratory Leads to New Methods of Quantum Communication – The Chicago Maroon

The University of Chicago, working with scientists from Argonne National Laboratory, has developed a new fiber-optic quantum loop to expand quantum communication experiments. The 52-mile-long loop, consisting of two 26-mile cables that link Argonne to the Illinois Tollway near suburban Bolingbrook, is one of the longest ground-based channels for quantum communication in the country.

This loop network gives researchers a platform for replicable testing of using quantum entanglement to send unhackable information over long distances, according to UChicago News. Researchers with both Argonne and UChicago plan to utilize this loop to examine and harness the properties of quantum entanglement. This phenomenon links two (or more) particles so that they are in a shared state such that whatever happens to one immediately affects the other, no matter how far apart they have traveled.

David Awschalom, principal investigator and professor of molecular engineering at the University of Chicago, believes that the establishment of the loop will help both the city of Chicago and the nation to build a similar network to securely transmit information and data over long distances.

The loop will enable us to identify and address challenges in operating a quantum network and can be scaled to test and demonstrate communication across even greater distances to help lay the foundation for a quantum internet, he said.

According to Argonne National Laboratory, researchers performed a series of experiments aimed to transmit signals using photon emission from ensembles of ions in the loop. These ions can serve as a form of memory for the loop. By creating this functional quantum memory, researchers can optimize quantum communication to form a quantum internet, a highly secure network of quantum computers and other quantum devices.

The research performed by the University of Chicago and Argonne National Laboratory will lead to optimization of data collection and the internet, according to Paul Kearns, director of Argonne National Laboratory.

Along with the UChicago quantum loop, Argonne National Laboratory is working with Fermi National Accelerator Laboratory to plan and develop a similar two-way quantum link network. When the two projects are connected, it will form one of the longest networks that can be used to send secure information using quantum physics, according to Argonne National Laboratory.

Both Argonne National Laboratory and the University of Chicago are members of the Chicago Quantum Exchange, a community hub of researchers aimed at advancing academic and industrial efforts to understand quantum information. Funding for the quantum loop was provided by the U.S. Department of Energy.

Researchers move closer to faster-charging Li-ion batteries; real-time tracking of Li ions in LTO – Green Car Congress

A team of scientists led by the US Department of Energys (DOE) Brookhaven National Laboratory and Lawrence Berkeley National Laboratory has captured in real time how lithium ions move in lithium titanate (LTO), a fast-charging battery electrode material made of lithium, titanium, and oxygen. They discovered that distorted arrangements of lithium and surrounding atoms in LTO intermediates (structures of LTO with a lithium concentration in between that of its initial and end states) provide an express lane for the transport of lithium ions.

Their discovery, reported in Science, could provide insights into designing improved battery materials for the rapid charging of electric vehicles and portable consumer electronics such as cell phones and laptops.

Consider that it only takes a few minutes to fill up the gas tank of a car but a few hours to charge the battery of an electric vehicle Figuring out how to make lithium ions move faster in electrode materials is a big deal, as it may help us build better batteries with greatly reduced charging time.

co-corresponding author Feng Wang, a materials scientist in Brookhaven Labs Interdisciplinary Sciences Department

Graphite is commonly employed as the anode in state-of-the-art lithium-ion batteries, but for fast-charging applications, LTO is an appealing alternative. LTO can accommodate lithium ions rapidly, without suffering from lithium plating (the deposition of lithium on the electrode surface instead of internally).

As LTO accommodates lithium, it transforms from its original phase (Li4Ti5O12) to an end phase (Li7Ti5O12)both of which have poor lithium conductivity. Thus, scientists have been puzzled as to how LTO can be a fast-charging electrode.

Reconciling this seeming paradox requires knowledge of how lithium ions diffuse in intermediate structures of LTO (those with a lithium concentration in between that of Li4Ti5O12 and Li7Ti5O12), rather than a static picture derived solely from the initial and end phases. However, performing such characterization is a non-trivial task. Lithium ions are light, making them elusive to traditional electron- or x-ray-based probing techniquesespecially when the ions are shuffling rapidly within active materials, such as LTO nanoparticles in an operating battery electrode.

In this study, the scientists were able to track the migration of lithium ions in LTO nanoparticles in real time by designing an electrochemical cell to operate inside a transmission electron microscope (TEM). This electrochemical cell enabled the team to conduct electron energy-loss spectroscopy (EELS) during battery charge and discharge.

In EELS, the change in energy of electrons after they have interacted with a sample is measured to reveal information about the samples local chemical states. In addition to being highly sensitive to lithium ions, EELS, when carried out inside a TEM, provides the high resolution in both space and time needed to capture ion transport in nanoparticles.

A schematic of the mini electrochemical cell that the scientists built to chase lithium ions (orange) moving in the lattice of LTO (blue).

The team tackled a multifold challenge in developing the electrochemically functional cellmaking the cell cycle like a regular battery while ensuring it was small enough to fit into the millimeter-sized sample space of the TEM column. To measure the EELS signals from the lithium, a very thin sample is needed, beyond what is normally required for the transparency of probing electrons in TEMs.

co-author and senior scientist Yimei Zhu, who leads the Electron Microscopy and Nanostructure Group in Brookhavens Condensed Matter Physics and Materials Science (CMPMS) Division

The resulting EELS spectra contained information about the occupancy and local environment of lithium at various states of LTO as charge and discharge progressed.

To decipher the information, scientists from the Computational and Experimental Design of Emerging Materials Research (CEDER) group at Berkeley and the Center for Functional Nanomaterials (CFN) at Brookhaven simulated the spectra. On the basis of these simulations, they determined the arrangements of atoms from among thousands of possibilities. To determine the impact of the local structure on ion transport, the CEDER group calculated the energy barriers of lithium-ion migration in LTO, using methods based on quantum mechanics.

Computational modeling was very important to understand how lithium can move so fast through this material. As the material takes up lithium, the atomic arrangement becomes very complex and difficult to conceptualize with simple transport ideas. Computations were able to confirm that the crowding of lithium ions together makes them highly mobile.

co-corresponding author and CEDER group leader Gerbrand Ceder, Chancellors Professor in the Department of Materials Science and Engineering at UC Berkeley and a senior faculty scientist in the Materials Science Division at Berkeley Lab

The teams analysis revealed that LTO has metastable intermediate configurations in which the atoms are locally not in their usual arrangement. These local polyhedral distortions lower the energy barriers, providing a pathway through which lithium ions can quickly travel.

A movie of lithium ions quickly moving along easy pathways in intermediate configurations of LTO. Imagine the LTO lattice as a racecar obstacle course that the lithium ions have to navigate around. In its original phase (Li4Ti5O12) and the end phase it transforms into to accommodate lithium ions (Li7Ti5O12), LTO has atomic configurations in which many obstacles are in the way. Thus, lithium ions must travel slowly through the obstacle course. But in intermediate configurations of LTO (such as the Li5+xTi5O12 shown in the movie), local distortions in the arrangement of atoms surrounding lithium occur along the boundary of these two phases. These distortions slightly shovel the obstacles out of the way, giving rise to a fast lane for lithium ions to speed through.

Unlike gas freely flowing into your cars gas tank, which is essentially an empty container, lithium needs to fight its way into LTO, which is not a completely open structure. To get lithium in, LTO transforms from one structure to another. Typically, such a two-phase transformation takes time, limiting the fast-charging capability. However, in this case, lithium is accommodated more quickly than expected because local distortions in the atomic structure of LTO create more open space through which lithium can easily pass. These highly conductive pathways happen at the abundant boundaries existing between the two phases.

Feng Wang

Next, the scientists will explore the limitations of LTOsuch as heat generation and capacity loss associated with cycling at high ratesfor real applications. By examining how LTO behaves after repeatedly absorbing and releasing lithium at varying cycling rates, they hope to find remedies for these issues. This knowledge will inform the development of practically viable electrode materials for fast-charging batteries.

We look forward to examining transport behaviors in fast-charging electrodes more closely by fitting our newly developed electrochemical cell to the powerful electron and x-ray microscopes at Brookhavens CFN and National Synchrotron Light Source II (NSLS-II). By leveraging these state-of-the-art tools, we will be able to gain a complete view of lithium transport in the local and bulk structures of the samples during cycling in real time and under real-world reaction conditions.

Feng Wang

The scientists carried out the experimental work using TEM facilities in Brookhavens CMPMS Division and the theoretical work using computational resources of Brookhavens Scientific Data and Computing Center (part of the Computational Science Initiative). Both CFN and NSLS-II are DOE Office of Science User Facilities. The research was supported by the Laboratory Directed Research and Development program at Brookhaven; DOEs Office of Energy Efficiency and Renewable Energy (EERE), Vehicle Technologies Office (VTO), under the Advanced Battery Materials Research program; DOEs Offices of Basic Energy Sciences and EERE VTO; and the National Science Foundation.
