Darlene English
Most people look at the night sky, and wonder. Darlene English strives to help uncover some of the mystery.
There are few astronomers in Canada, the Memorial University Grenfell Campus physics lab instructor says, and fewer jobs.
She has a masters degree in astronomy from St. Marys University and years ago worked in Victoria, B.C. as a research assistant. She has dabbled in astronomy over the years as has her husband Doug Forbes, also an astronomer and physics instructor at Grenfell but she now has more than 20 years experience in the field of physics. Despite an eye on the sky, she has had a fulfilling career in Corner Brook.
More than two decades ago, Forbes applied for funding for an observatory at Grenfell. There was no large scale telescope in the province when he arrived here to teach. Grenfells is now the only one, and the largest in Atlantic Canada.
Since spring 2012, English has been able to again focus her spare time on her passion astronomy.
Her research involves a class of variable star known as the SX Phoenicis star. These stars pulsate over time, varying its light. These stars are about 50 per cent larger than the sun, she said, so the fact their radius changes is quite a spectacular phenomenon.
The interest of studying these stars is important in understanding stellar evolution.
How stars are born, what happens when they age, and eventually go through all the life stages, and die, she said.

An international group of astronomers including a scientist from the University of Gttingen has found an explanation of the long-standing mystery of why magnetic fields are more common among cool white dwarf stars than among young and hotter ones. The results were published in Nature. Press release No. 242/2014
Magnetic white dwarfs appear younger than they are Scientists from Gttingen University link magnetic fields to atmospheric convection
(pug) An international group of astronomers including a scientist from the University of Gttingen has found an explanation of the long-standing mystery of why magnetic fields are more common among cool white dwarf stars than among young and hotter ones. The researchers showed that strong magnetic fields are sufficient to suppress convection over the entire surface in cool magnetic white dwarfs, which inhibits their cooling evolution relative to weakly magnetic and non-magnetic ones, making them appear younger than they truly are. The results were published in Nature.
White dwarf (WD) stars are the remnants of intermediate mass stars at the final stage of their evolution. Since the white dwarf does not burn any fusion in its interior, it cools down from the time it is born pretty much like a pot of hot water left out the fire. Therefore, the surface temperature of any white dwarf star can be uniquely linked to its age.
If a star-progenitor has a magnetic field, then the contraction process during the formation of the WD will amplify this field by many orders of magnitude. This is how magnetic white dwarf stars (MWD) appear. Because magnetic fields are expected to decay with time, and because surface temperature also drops when WD cools down, one might expect to detect more non-magnetic or weakly magnetic objects at cool temperatures, but the opposite is observed.
The researchers found that the magnetic field may have a global control of surface convection in cool MWD stars which explains their puzzling characteristics. By analyzing the light variability of the cool dwarf WD 1953-011 we found a direct link between the strength of local magnetic field and the local surface temperature, explains Dr. Denis Shulyak from Gttingen Universitys Institute for Astrophysics. This suggests that the magnetic field suppresses atmospheric convection, leading to dark spots in the most magnetized areas similar to that occurring in sunspots.
But if the global magnetic field is very strong (hundreds of kilogauss and above), it can then inhibit convective motions everywhere over the stellar surface and deep into the interior of the star. Because convection transfers a significant fraction of the total energy flux from subphotospheric layers to the surface in WD stars with surface temperatures below approximately 12,000 K, its suppression by strong magnetic fields will result in decrease of the stellar luminosity. If we now remember that cooling times of WD stars are inversely proportional to luminosities, then objects with globally suppressed convection should have longer cooling timescales than their non-magnetic or weakly magnetic twins. Therefore, magnetic suppression of cooling provides a natural explanation for the increase in number of MWD stars at cool temperatures where convection is the dominant energy transport mechanism. This result fully agrees with our theoretical predictions, says Shulyak.
The analysis of photometric variability of cool MWD stars and their unexpectedly high frequencies compared to non-magnetic stars, as well as the high dispersion of their space velocities (which carries the information about the stellar age) all these observational facts ultimately point towards the existence of a magnetic suppression of cooling in strongly magnetic, isolated WD stars.
If we imagine the WD star as an open pot with hot water left on the table to cool, then covering it with a lid will slow its cooling time. Strong magnetic field is this kind of lid in WD stars which suppresses convection and therefore heat loses. Our findings imply that the ages of most magnetic and cool MWD stars can be underestimated. This prompts a revision of our interpretation of the MWD cooling sequence that, in turn, may require tuning of our understanding of the evolution of the Galaxy and the Universe, concludes Shulyak.

In 1966, some Massachusetts Institute of Technology researchers reckoned that they could develop computer vision as a summer project, perhaps even get a few smart undergrads to complete the task.
The world has been working on the problem ever since.
Computer vision is where computers recognize objects like people do. Thats a tree. Hes Carlos. And so on. Its one of a number of tasks we consider essential for generalized artificial intelligence, in which machines can act and reason as humans do.
While weve been making some considerable headway in computer vision, especially in recent years, that it has taken 50 years longer than expected shows why AI (artificial intelligence) is such as difficult and elusive goal.
How much progress is being made? Its really hard to get a handle on that, said Beau Cronin, a Salesforce.com product manager currently working on some AI-influenced technologies for the company. Cronin spoke Friday at the OReilly Strata + Hadoop World conference, in New York.
The main theme of the conference was big data. The need for big data analytics has given AI research a shot in the arm. Today the titans of the Internet industryApple, Google, Facebook, Microsoft, IBMare putting AI research into the drivers seat, pushing forward the state of the art for seemingly routine tasks such as ad targeting and personalized assistance.
But in many ways, we are no closer to achieving an overall general artificial intelligence, in the sense that a computer can behave like a human, Cronin observed. Systems that use AI technologies, such as machine learning, are defined to execute very narrowly defined tasks.
The state of AI has always been hard to assess, Cronin said. AI systems are hard to evaluate: They may excel in one area but fall short in another, similar task. Many projects, even sometimes very well-funded ones, go nowhere.
Even basic definitions of AI are still not locked down. When two people talk about AI, one may be referring to a specific machine learning algorithm while the other may be talking about autonomous robots. AI still attracts oddballs, lone wolves working in their basements 10 hours a week hoping to solve the AI problem once and for all.
The overambitious Summer of Vision MIT project in the 60s pointed out one of the major stumbling blocks for AI research, called Moravecs Paradox.

Ask Watson or Siri: Artificial intelligence is as elusive as ever
SINGAPORE: A Non-Resident Indian-owned Clone Algo Technologies, known for developing artificial intelligence for algorithms used in trading foreign exchange, gold, crude oil and shares, was actively traded at $ 12 OTCQB in New York.
The opening price of $ 12 per share yesterday has valued the group at $ 8.534 billion based on 711.15 million shares, which included the shares of Clone Algo Inc, proposed to be merged along with Clone Algo Technologies in the coming days.
The group develops artificial intelligence for algorithms which are used to trade the foreign exchange, gold, crude oil and shares automatically without traders.
Clone Algo Technologies founder and chairman Niraj Goel welcomed the first opening in New York last night. "The opening price was as per our expectations," he told PTI.
This has raised the asset value of Ludhiana-born Goel to $ 12.95 billion including his stakes in other companies and assets, placing him among the top five technology billionaires in Asia.
"Investors are switching from traditional old economy stocks to innovation-driven social media technology stocks. Fully algorithmic trading and use of artificial intelligence in timing technology now commands a major market share globally," the 45-year-old innovator said.
The entrepreneur said the success of New York listing gives him the confidence to propose a dual listing in London and Singapore as well.
"We expect to list in London by year end and follow up with Singapore by second half of next year," said Goel.
"We are looking to expand into the other markets. We are going to set up new offices and hire new staff," he said.
The expansion includes a major R&D base in the U.S. and marketing networks out of Munich and Hong Kong.
