Oprah Winfrey Seeks a Younger Audience to Bolster a Flagging Empire

Stephanie Diani for The New York Times

Oprah Winfrey spoke last month at a convention held by O, The Oprah Magazine, in Los Angeles.

LOS ANGELES — It’s not easy to find a fresh way to photograph Oprah Winfrey.

That’s why the editors of O, The Oprah Magazine, recently tried to create a shot that recalled the glory days of Ms. Winfrey’s syndicated talk show. They arranged to photograph her for its April 2013 issue as she stepped onstage to speak to 5,000 attendees at the magazine’s annual conference, a New Age slumber party of sorts for women held at the convention center here last month. When Ms. Winfrey confidently strode out dressed in a sea foam green V-neck dress and a pair of perilously tall ruby red stilettos, the audience collectively leapt to its feet and shrieked at the sight of her.

“I love you, Oprah,” some women shouted, while other fans brushed away tears. “I love you back,” she responded in her signature commanding voice. “It’s no small thing to get the dough to come here.”

Ms. Winfrey, who used to receive this kind of applause from fans five days a week, has had fewer such receptions since the talk show she hosted for 25 years ended 18 months ago. The cable network OWN, which she started with Discovery Communications, is emerging from low ratings and management shake-ups. And without a regular presence on daytime network television, she cannot steer traffic to her other products as easily as in the past. Her magazine, in particular, has experienced a decline in advertising revenue and newsstand sales since the talk show finished.

“She’s still Oprah. But she’s still struggling,” said Janice Peck, an associate professor of journalism and mass communication at the University of Colorado who wrote the 2008 book “The Age of Oprah.” “I think she’s scared, even though she’s very, very rich and she’s always going to be very, very rich. The possibility of failure, it’s quite scary.”

Ms. Winfrey, 58, has shown some signs of strain. She arrived at the conference with faint shadows under her eyes and announced to her best friend, Gayle King, and the audience simultaneously that she had a breast cancer scare the week before. (It was ultimately a false alarm.) When Ms. King grew visibly upset, one woman chided Ms. Winfrey for not telling her friend ahead of time and ordered her to apologize to Ms. King — all before an audience. Ms. Winfrey also did not hide her dissatisfaction with the criticism she had faced. She told the audience, “the press tried to cut me off at the knees” in its coverage of OWN, and bristled at questions about the challenges her magazine confronted.

“I don’t care what the form is,” Ms. Winfrey said with the conviction of a preacher. “I care about what the message is.”

With signs of progress at OWN, Ms. Winfrey now has more time to devote to other media platforms — her magazine, her radio channel on XM Satellite Radio, her Facebook page, which has 7.8 million subscribers, her Twitter account, which has nearly 15 million followers, and her latest content channel on The Huffington Post.

“It’s all an opportunity to speak to people,” Ms. Winfrey said as she sat for an interview during the conference, a pair of glittery gold stilettos slung in her hand and a couple of handlers in the corner quietly tapping away at smartphones. She pushed aside a bottle of sparkling water, a glass with a silver straw and a delicate orchid placed before her and spoke frankly about her plans.

“Ultimately, you have to make money because you are a business. I let other people worry about that. I worry about the message. I am always, always, always about holding true to the vision and the message, and when you are true to that, then people respond.”

When it comes to the magazine, Ms. Winfrey said her staff prepared her to expect a 25 percent decline in newsstand sales after the talk show ended. (It has been closer to 22 percent.) And while she acknowledged that she enjoyed “holding the magazine in my hand,” she was pragmatic about print’s future and said she would stop publishing a print magazine if it were not profitable.

“Obviously, the show was helping in ways that you know I hadn’t accounted for,” Ms. Winfrey said. “I’m not interested, you know, in bleeding money.”

Ms. Winfrey, who spoke in a conference room over the roars of an expectant crowd in the convention space below, said she knew that her brand’s strength stemmed from how she resonated with a breadth of viewers.

Solar power plants burden the counties that host them

When it comes to attracting business to California's eastern deserts, Inyo County is none too choosy.

Since the 19th century the sparsely populated county has worked to attract industries shunned by others, including gold, tungsten and salt mining. The message: Your business may be messy, but if you plan to hire our residents, the welcome mat is out.

So the county grew giddy last year as it began to consider hosting a huge, clean industry. BrightSource Energy, developer of the proposed $2.7-billion Hidden Hills solar power plant 230 miles northeast of Los Angeles, promised a bounty of jobs and a windfall in tax receipts. In a county that issued just six building permits in 2011, Inyo officials first estimated that property taxes from the facility would boost the general fund 17%.

But upon closer inspection, the picture didn't seem so rosy.

An economic consultant hired by the county found that property tax revenue would be a fraction of the customary amount because portions of the plant qualifiy for a solar tax exclusion. Fewer than 10 local workers would land permanent positions — and just 5% of the construction jobs would be filled by county residents. And construction workers are likely to spend their money across the nearby state line, in Nevada.

Worse, the project would cost the county $11 million to $12 million during the 30-month construction phase, with much of the money going to upgrade a historic two-lane road to the plant. Once the plant begins operation, the county estimates taxpayers will foot the bill for nearly $2 million a year in additional public safety and other services.

Two of California's other Mojave Desert counties, Riverside and San Bernardino, have made similar discoveries. Like Inyo, they are now pushing back against solar developers, asking them to cover the costs of servicing the new industry.

"Southern California is going to become the home to the state's ability to meet its solar goals," said Gerry Newcombe, public works director for San Bernardino County. "That's great, but where are the benefits to the county?"

Desert counties also are anticipating costly shifts in land use, including the conversion of taxable private property into habitat for endangered species. Solar developers are required to buy land to offset the loss of habitat caused by their projects. Once the property is acquired, it cannot be developed, which reduces its potential for tax revenue.

Two of the largest solar plants in the world are under construction in San Bernardino County. But county officials are not sure if revenue from the projects will offset the cost of additional fire and safety services, which analysts say will amount to millions of dollars a year.

For example, the $2.2-billion Ivanpah solar project at the county's eastern border has agreed to pay $377,000 annually, but that may not be enough to cover the county's new costs related to the plant. The county doesn't know how much solar plants will drain from its budget because the projects are being planned and approved too quickly for adequate analysis, officials say.

"We really support private development and generating jobs," Newcombe said. "On the other hand, I am concerned that it's going too fast. I don't know that we've had a chance to appreciate the long-term impacts."

The county is also worried because most of the land inside its borders is owned by the federal government, and up to 1 million acres of that — nearly 8% of the county — could be set aside for solar development, removing it from public access and recreational opportunities, Newcombe said.

Counties that object to the pace of development, however, have been scolded for standing in the way of progress. Not only is renewable energy a priority of the Obama administration, it is also the darling of California's chief executive.

Gov. Jerry Brown has vowed to "crush" opponents of solar projects. At the launch of a solar farm near Sacramento, the governor pledged: "It's not easy. There are gonna be screw-ups. There are gonna be bankruptcies. There'll be indictments and there'll be deaths. But we're gonna keep going — and nothing's gonna stop me."

Counties have little say because the state controls planning and licensing of large-scale projects. The California Energy Commission issues the permits for utility-scale solar farms, and counties depend on the commission's staff to look out for their interests.

To the extent that California counties are pushing back against industrial solar, the rebellion began in Riverside County more than a year ago.

Some 20 utility-scale solar farms are proposed in the eastern stretch of the county on 118,000 acres of federal land along the Interstate 10 corridor between Desert Center and Blythe.

The Riverside County Board of Supervisors considered charging companies a franchise fee to offset the effects on roads and public services and to compensate for the loss of recreation and tourism access to the 185 square miles of federal land. Local officials saw it as a matter of fairness. Public utilities pay 2% of gross receipts to the county, for example.

"The solar companies are the beneficiaries of huge government loans, tax credits and, most critically for me, property tax exemptions, at the expense of taxpayers," said county Supervisor John Benoit, referring to a variety of taxpayer-supported loans and grants available to large solar projects as part of the Obama administration's renewable energy initiative. "I came to the conclusion that my taxpayers need to get something back."

M.I.T. Lab Hatches Ideas, and Companies, by the Dozens

HOW do you take particles in a test tube, or components in a tiny chip, and turn them into a $100 million company?

Dr. Robert Langer, 64, knows how. Since the 1980s, his Langer Lab at the Massachusetts Institute of Technology has spun out companies whose products treat cancer, diabetes, heart disease and schizophrenia, among other diseases, and even thicken hair.

The Langer Lab is on the front lines of turning discoveries made in the lab into a range of drugs and drug delivery systems. Without this kind of technology transfer, the thinking goes, scientific discoveries might well sit on the shelf, stifling innovation.

A chemical engineer by training, Dr. Langer has helped start 25 companies and has 811 patents, issued or pending, to his name. That’s not too far behind Thomas Edison, who had 1,093. More than 250 companies have licensed or sublicensed Langer Lab patents.

Polaris Venture Partners, a Boston venture capital firm, has invested $220 million in 18 Langer Lab-inspired businesses. Combined, these businesses have improved the health of many millions of people, says Terry McGuire, co-founder of Polaris.

Along the way, Dr. Langer and his lab, including about 60 postdoctoral and graduate students at a time, have found a way to navigate some slippery territory: the intersection of academic research and the commercial market.

Over the last 30 years, many universities — including M.I.T. — have set up licensing offices that oversee the transfer of scientific discoveries to companies. These offices have become a major pathway for universities seeking to put their research to practical use, not to mention add to their revenue streams.

In the sciences in particular, technology transfer has become a key way to bring drugs and other treatments to market. “The model of biomedical innovation relies on research coming out of universities, often funded by public money,” says Josephine Johnston, director of research at the Hastings Center, a bioethics research organization based in Garrison, N.Y.

Just a few of the products that have emerged from the Langer Lab are a small wafer that delivers a dose of chemotherapy used to treat brain cancer; sugar-sequencing tools that can be used to create new drugs like safer and more effective blood thinners; and a miniaturized chip (a form of nanotechnology) that can test for diseases.

The chemotherapy wafer, called the Gliadel, is licensed by Eisai Inc. The company behind the sugar-sequencing tools, Momenta Pharmaceuticals, raised $28.4 million in an initial public offering in 2004. The miniaturized chip is made by T2Biosystems,  which completed a $23 million round of financing in the summer of 2011.

“It’s inconvenient to have to send things to a lab,” so the company is trying to develop more sophisticated methods, says Dr. Ralph Weissleder, a co-founder, with Dr. Langer and others, of T2Biosystems and a professor at Harvard Medical School.

FOR Dr. Langer, starting a company is not the same as it was, say, for Mark Zuckerberg with Facebook. “Bob is not consumed with any one company,” says H. Kent Bowen, an emeritus professor of business administration at Harvard Business School who wrote a case study on the Langer Lab. “His mission is to create the idea.”

Dr. Bowen observes that there are many other academic laboratories, including highly productive ones, but that the Langer Lab’s combination of people, spun-out companies and publications sets it apart. He says Dr. Langer “walks into the great unknown and then makes these discoveries.”

Dr. Langer is well known for his mentoring abilities. He is “notorious for replying to e-mail in two minutes, whether it’s a lowly graduate school student or the president of the United States,” says Paulina Hill, who worked in his lab from 2009 to 2011 and is now a senior associate at Polaris Venture Partners. (According to Dr. Langer, he has corresponded directly with President Obama about stem cell research and federal funds for the sciences.)

Dr. Langer says he looks at his students “as an extended family,” adding that “I really want them to do well.”

And they have, whether in business or in academia, or a combination of the two. One former student, Ram Sasisekharan, helped found Momenta and now runs his own lab at M.I.T. Ganesh Venkataraman Kaundinya is Momenta’s chief scientific officer and senior vice president for research.

Hongming Chen is vice president of research at Kala Pharmaceuticals. Howard Bernstein is chief scientific officer at Seventh Sense Biosystems, a blood-testing company. Still others have taken jobs in the law or in government.

Dr. Langer says he spends about eight hours a week working on companies that come out of his lab. Of the 25 that he helped start, he serves on the boards of 12 and is an informal adviser to 4. All of his entrepreneurial activity, which includes some equity stakes, has made him a millionaire. But he says he is mainly motivated by a desire to improve people’s health.

Operating from the sixth floor of the David H. Koch Institute for Integrative Cancer Research on the M.I.T. campus in Cambridge, Mass., Dr. Langer’s lab has a research budget of more than $10 million for 2012, coming mostly from federal sources.

The research in labs like Dr. Langer’s is eyed closely by pharmaceutical companies. While drug companies employ huge research and development teams, they may not be as freewheeling and nimble, Dr. Langer says. The basis for many long-range discoveries has “come out of academia, including gene therapy, gene sequencing and tissue engineering,” he says.

He has served as a consultant to pharmaceutical companies. Their large size, he says, can end up being an impediment.

“Very often when you are going for real innovation,” he says, “you have to go against prevailing wisdom, and it’s hard to go against prevailing wisdom when there are people who have been there for a long time and you have some vice president who says, ‘No, that doesn’t make sense.’ ”

Pharmaceutical companies are eager to tap into the talent at leading research universities. In 2008, for example, Washington University in St. Louis announced a $25 million pact with Pfizer to collaborate more closely on biomedical research.

But in some situations, the close — critics might say cozy — ties between business and academia have the potential to create conflicts of interest.

There was a controversy earlier this year when it was revealed that the president of the University of Texas M.D. Anderson Cancer Center owned stock in Aveo Oncology, which had announced earlier that the university would be leading clinical trials of one of its cancer drugs.  Last month, the University of Texas announced that he would be allowed to keep his ties with three pharmaceutical companies, including Aveo Oncology; his holdings will be placed in a blind trust.

Lobbying, a Windfall and a Leader’s Family

Gilles Sabrie for The New York Times

Ping An, one of China’s largest financial services companies, is building a 115-story office tower in Shenzhen. The company is a $50 billion powerhouse now worth more than A.I.G., MetLife or Prudential.

SHENZHEN, China — The head of a financially troubled insurer was pushing Chinese officials to relax rules that required breaking up the company in the aftermath of the Asian financial crisis.

The survival of Ping An Insurance was at stake, officials were told in the fall of 1999. Direct appeals were made to the vice premier at the time, Wen Jiabao, as well as the then-head of China’s central bank — two powerful officials with oversight of the industry.

“I humbly request that the vice premier lead and coordinate the matter from a higher level,” Ma Mingzhe, chairman of Ping An, implored in a letter to Mr. Wen that was reviewed by The New York Times.

Ping An was not broken up.

The successful outcome of the lobbying effort would prove monumental.

Ping An went on to become one of China’s largest financial services companies, a $50 billion powerhouse now worth more than A.I.G., MetLife or Prudential. And behind the scenes, shares in Ping An that would be worth billions of dollars once the company rebounded were acquired by relatives of Mr. Wen.

The Times reported last month that the relatives of Mr. Wen, who became prime minister in 2003, had grown extraordinarily wealthy during his leadership, acquiring stakes in tourist resorts, banks, jewelers, telecommunications companies and other business ventures.

The greatest source of wealth, by far, The Times investigation has found, came from the shares in Ping An bought about eight months after the insurer was granted a waiver to the requirement that big financial companies be broken up.

Long before most investors could buy Ping An stock, Taihong, a company that would soon be controlled by Mr. Wen’s relatives, acquired a large stake in Ping An from state-owned entities that held shares in the insurer, regulatory and corporate records show. And by all appearances, Taihong got a sweet deal. The shares were bought in December 2002 for one-quarter of the price that another big investor — the British bank HSBC Holdings — paid for its shares just two months earlier, according to interviews and public filings.

By June 2004, the shares held by the Wen relatives had already quadrupled in value, even before the company was listed on the Hong Kong Stock Exchange. And by 2007, the initial $65 million investment made by Taihong would be worth $3.7 billion.

Corporate records show that the relatives’ stake of that investment most likely peaked at $2.2 billion in late 2007, the last year in which Taihong’s shareholder records were publicly available. Because the company is no longer listed in Ping An’s public filings, it is unclear if the relatives continue to hold shares.

It is also not known whether Mr. Wen or the central bank chief at the time, Dai Xianglong, personally intervened on behalf of Ping An’s request for a waiver, or if Mr. Wen was even aware of the stakes held by his relatives.

But internal Ping An documents, government filings and interviews with bankers and former senior executives at Ping An indicate that both the vice premier’s office and the central bank were among the regulators involved in the Ping An waiver meetings and who had the authority to sign off on the waiver.

Only two large state-run financial institutions were granted similar waivers, filings show, while three of China’s big state-run insurance companies were forced to break up. Many of the country’s big banks complied with the breakup requirement — enforced after the financial crisis because of concerns about the stability of the financial system — by selling their assets in other institutions.

Ping An issued a statement to The Times saying the company strictly complies with rules and regulations, but does not know the backgrounds of all entities behind shareholders. The company also said “it is the legitimate right of shareholders to buy and sell shares between themselves.”

In Beijing, China’s foreign ministry did not return calls seeking comment for this article. Earlier, a Foreign Ministry spokesman sharply criticized the investigation by The Times into the finances of Mr. Wen’s relatives, saying it “smears China and has ulterior motives.”

Larry Hagman dead at 81, portrayed notorious TV villain J.R. Ewing

(Reuters) – Larry Hagman, who created one of American television’s most supreme villains in the conniving, amoral oilman J.R. Ewing of “Dallas,” died on Friday, the Dallas Morning News reported. He was 81.

Hagman died at a Dallas hospital of complications from his battle with throat cancer, the newspaper said, quoting a statement from his family. He had suffered from liver cancer and cirrhosis of the liver in the 1990s after decades of drinking.

Hagman’s mother was stage and movie star Mary Martin and he became a star himself in 1965 on “I Dream of Jeannie,” a popular television sitcom in which he played Major Anthony Nelson, an astronaut who discovers a beautiful genie in a bottle.

“Dallas,” which made its premiere on the CBS network in 1978, made Hagman a superstar. The show quickly became one of the network’s top-rated programs, built an international following and inspired a spin-off, imitators and a revival in 2012.

“Dallas” was the night-time soap-opera story of a Texas family, fabulously wealthy from oil and cattle, and its plot brimmed with back-stabbing, double-dealing, family feuds, violence, adultery and other bad behavior.

In the middle of it all stood Hagman’s black-hearted J.R. Ewing – grinning wickedly in a broad cowboy hat and boots, plotting how to cheat his business competitors and cheat on his wife. He was the villain TV viewers loved to despise during the show’s 356-episode run from 1978 to 1991.

“I really can’t remember half of the people I’ve slept with, stabbed in the back or driven to suicide,” Hagman said of his character in Time magazine.

In his autobiography, “Hello Darlin’: Tall (and Absolutely True) Tales About My Life,” Hagman wrote that J.R. originally was not to be the focus of “Dallas” but that changed when he began ad-libbing on the set to make his character more outrageous and compelling.

‘WHO SHOT J.R.?’

To conclude its second season, the “Dallas” producers put together one of U.S. television’s most memorable episodes in which Ewing was shot by an unseen assailant. That gave fans months to fret over whether J.R. would survive and who had pulled the trigger. In the show’s opening the following season, it was revealed that J.R.’s sister-in-law, Kristin, with whom he had been having an affair, was behind the gun.

Hagman said an international publisher offered him $ 250,000 to reveal who had shot J.R. and he considered giving the wrong information and taking the money, but in the end, “I decided not to be so like J.R. in real life.”

The popularity of “Dallas” made Hagman one of the best-paid actors in television and earned him a fortune that even a Ewing would have coveted. He lost some of it, however, in bad oil investments before turning to real estate.

“I have an apartment in New York, a ranch in Santa Fe, a castle in Ojai outside of L.A., a beach house in Malibu and thinking of buying a place in Santa Monica,” Hagman said in a Chicago Tribune interview.

An updated “Dallas” series began in June 2012 on the TNT network with Hagman reprising his J.R. role with original cast members Linda Gray, who played J.R.’s long-suffering wife, Sue Ellen, and Patrick Duffy, who was his brother Bobby. The show was to focus on the sons of J.R. and Bobby.

Hagman had a wide eccentric streak. When he first met actress Lauren Bacall, he licked her arm because he had been told she did not like to be touched and he was known for leading parades on the Malibu beach and showing up at a grocery store in a gorilla suit. Above his Malibu home flew a flag with the credo “Vita Celebratio Est (Life Is a Celebration)” and he lived hard for many years.

In 1967, rock musician David Crosby turned him on to LSD, which Hagman said took away his fear of death, and Jack Nicholson introduced him to marijuana because Nicholson thought he was drinking too much.

Hagman had started drinking as a teenager and said he did not stop until the moment in 1992 when his doctor told him he had cirrhosis of the liver and could die within six months. Hagman wrote that for the past 15 years he had been drinking about four bottles of champagne a day, including while on the “Dallas” set.

LIVER TRANSPLANT

In July 1995, he was diagnosed with liver cancer, which led him to quit smoking, and a month later he underwent a liver transplant.

After giving up his vices, Hagman said he did not lose his zest for life.

“It’s the same old Larry Hagman,” he told a reporter. “He’s just a littler sober-er.”

Hagman was born on September 21, 1931, in Weatherford, Texas, and his father was a lawyer who dealt with the Texas oil barons Hagman would later come to portray. He was still a boy when his parents divorced and he went to Los Angeles with Martin, who would become a Broadway and Hollywood musical star.

Hagman eventually landed in New York to pursue acting, making his stage debut there in “The Taming of the Shrew.” In New York, he married Maj Axelsson in 1954 while they were in a production of “South Pacific. The marriage produced two children, Heidi and Preston.

Hagman served in the Air Force, spending five years in Europe as the director of USO shows, and on his return to New York he took a starring role in the daytime soap “The Edge of Night.” His breakthrough came in 1965 when he landed the “I Dream of Jeannie” role opposite Barbara Eden.

In his later years, Hagman became an advocate for organ transplants and an anti-smoking campaigner. He also was devoted to solar energy, telling the New York Times he had a $ 750,000 solar panel system at his Ojai estate, and made a commercial in which he portrayed a J.R. Ewing who had forsaken oil for solar power. He was a longtime member of the Peace and Freedom Party, a minor leftist organization in California.

Hagman told the Times that after death he wanted his remains to be “spread over a field and have marijuana and wheat planted and harvest it in a couple of years and then have a big marijuana cake, enough for 200 to 300 people. People would eat a little of Larry.”

Scientists See Advances in Deep Learning, a Part of Artificial Intelligence

Hao Zhang/The New York Times

A voice recognition program translated a speech given by Richard F. Rashid, Microsoft’s top scientist, into Mandarin Chinese.

Using an artificial intelligence technique inspired by theories about how the brain recognizes patterns, technology companies are reporting startling gains in fields as diverse as computer vision, speech recognition and the identification of promising new molecules for designing drugs.

The advances have led to widespread enthusiasm among researchers who design software to perform human activities like seeing, listening and thinking. They offer the promise of machines that converse with humans and perform tasks like driving cars and working in factories, raising the specter of automated robots that could replace human workers.

The technology, called deep learning, has already been put to use in services like Apple’s Siri virtual personal assistant, which is based on Nuance Communications’ speech recognition service, and in Google’s Street View, which uses machine vision to identify specific addresses.

But what is new in recent months is the growing speed and accuracy of deep-learning programs, often called artificial neural networks or just “neural nets” for their resemblance to the neural connections in the brain.

“There has been a number of stunning new results with deep-learning methods,” said Yann LeCun, a computer scientist at New York University who did pioneering research in handwriting recognition at Bell Laboratories. “The kind of jump we are seeing in the accuracy of these systems is very rare indeed.”

Artificial intelligence researchers are acutely aware of the dangers of being overly optimistic. Their field has long been plagued by outbursts of misplaced enthusiasm followed by equally striking declines.

In the 1960s, some computer scientists believed that a workable artificial intelligence system was just 10 years away. In the 1980s, a wave of commercial start-ups collapsed, leading to what some people called the “A.I. winter.”

But recent achievements have impressed a wide spectrum of computer experts. In October, for example, a team of graduate students studying with the University of Toronto computer scientist Geoffrey E. Hinton won the top prize in a contest sponsored by Merck to design software to help find molecules that might lead to new drugs.

From a data set describing the chemical structure of 15 different molecules, they used deep-learning software to determine which molecule was most likely to be an effective drug agent.

The achievement was particularly impressive because the team decided to enter the contest at the last minute and designed its software with no specific knowledge about how the molecules bind to their targets. The students were also working with a relatively small set of data; neural nets typically perform well only with very large ones.

“This is a really breathtaking result because it is the first time that deep learning won, and more significantly it won on a data set that it wouldn’t have been expected to win at,” said Anthony Goldbloom, chief executive and founder of Kaggle, a company that organizes data science competitions, including the Merck contest.

Advances in pattern recognition hold implications not just for drug development but for an array of applications, including marketing and law enforcement. With greater accuracy, for example, marketers can comb large databases of consumer behavior to get more precise information on buying habits. And improvements in facial recognition are likely to make surveillance technology cheaper and more commonplace.

Artificial neural networks, an idea going back to the 1950s, seek to mimic the way the brain absorbs information and learns from it. In recent decades, Dr. Hinton, 64 (a great-great-grandson of the 19th-century mathematician George Boole, whose work in logic is the foundation for modern digital computers), has pioneered powerful new techniques for helping the artificial networks recognize patterns.

Modern artificial neural networks are composed of an array of software components, divided into inputs, hidden layers and outputs. The arrays can be “trained” by repeated exposures to recognize patterns like images or sounds.

These techniques, aided by the growing speed and power of modern computers, have led to rapid improvements in speech recognition, drug discovery and computer vision.

Deep-learning systems have recently outperformed humans in certain limited recognition tests.

Last year, for example, a program created by scientists at the Swiss A. I. Lab at the University of Lugano won a pattern recognition contest by outperforming both competing software systems and a human expert in identifying images in a database of German traffic signs.

The winning program accurately identified 99.46 percent of the images in a set of 50,000; the top score in a group of 32 human participants was 99.22 percent, and the average for the humans was 98.84 percent.

Lining up even earlier for Black Friday becomes a shop priority

In a tradition that seems to take a bigger slice of Thanksgiving every year, hordes of deal-sniffing shoppers descended on Southland stores Thursday, elbowing their way in search of toys, video games and that time-honored Black Friday symbol: cut-rate television sets. As nightfall came, they huddled in long lines, clutching coupons and hatching shopping strategies.

Rebecca Abbott, 42, of Torrance had it down to a science Thursday night. The accountant said she was out the door of the local Toys R Us store in 20 minutes with a shopping cart full of Christmas gifts for her two daughters. 

Her fourth time shopping on Black Friday, Abbott had spent a few hours in Toys R Us the day before scoping out her plan of attack. The first item on her list: a Rockstar Mickey Mouse doll, normally priced at $59.99 but selling for just $19.99.

"You have to have a strategy for this Black Friday madness," she said as she headed for the door. "First-timers will walk around all day looking at deals," Abbott said. "I got in, grabbed my stuff and got out." Her cart was overflowing with large toys — primarily Barbie and Mickey Mouse items.

At a Wal-Mart in Panorama City, just after 8 p.m., "it was really crazy, but you could still walk," said Marya Huaman, 23, as she left the store with her dad, her two infant sons and three bags full of Fisher-Price toys.

"No, you couldn't," scoffed her father, Edward Huaman. "I didn't see anyone fighting, but they will be soon. This is madness."

Last year, Thanksgiving night was marred by a pepper spray "shopping rage" incident at a Wal-Mart in Porter Ranch that injured at least seven people and forced employees to evacuate part of the store. One person was hospitalized.

Los Angeles Police Cmdr. Andy Smith said Thursday that the night appeared to be running smoothly across Los Angeles. "In general, I think things have gone really well," he said. "It sounds like the stores have taken proper precautions and everyone is aware of the hazards of Black Friday."

After retailers last year moved the opening bell for Black Friday sales to midnight, this year there were even more customers eager to get a jump on the traditional kickoff to the holiday shopping season. Wal-Mart, Sears and Toys R Us began rolling out their door busters at 8 p.m. on Turkey Day, followed by Target at 9 p.m. Macy's, Kohl's and Best Buy were set to open at midnight.

A handful of chains such as Kmart and Old Navy also had daytime hours on Thursday. And online merchants were touting bargains all day and night.

About 147 million shoppers are expected this all-important holiday weekend, with more logging in for online specials by Cyber Monday, according to the National Retail Federation. In all, the trade group estimated that holidays sales will rise 4.1% this year, to $586 billion.

"Though the Black Friday tradition is here to stay, there's no question that it has changed in recent years," NRF Chief Executive Matthew Shay said in a statement.

Many shoppers were perfectly content to queue up. At Best Buy electronic stores across the Southland, people waited for hours — and sometimes days — in tents before the midnight opening.

But many workers were angry about spending Turkey Day away from loved ones.

Frustrated retail employees and families have taken to creating online petitions at Change.org to beg companies not to cut into Thanksgiving dinners. More than 20 online petitions have popped up in recent weeks. Lines grew throughout the afternoon and into the evening as anxious shoppers surveyed the competition in line.

Throughout Southern California there were reports of lines wrapped around stores. In Glendale, more than 750 shoppers were lined up outside the Target at the Galleria.

For shoppers who just couldn't wait until Thursday night — much less Black Friday — some retailers opened their doors all day on Thanksgiving.

The sales weren't quite as glorious as the Black Friday specials that stores promise to roll out later. But they were pretty good nonetheless, shoppers said.

JoAnne Garcia walked into Kmart in Burbank in search of a roasting pan in which to cook her turkey. She walked out 90 minutes later, having shelled out $491, including $329 for an RCA 39-inch LCD flat-panel TV.

"The roasting pan was $14.99," Garcia said, laughing at how much she spent as she rolled her cart to the parking lot.

To the 53-year-old aerospace machinist, shopping on Thanksgiving made perfect sense.

Standing near a store display touting "Freak Out Pricing," Garcia explained her theory about shopping while cooking. "You get up, throw your turkey in the oven, and you come back and it's all done."
