Nanotubes Seen as an Alternative to Silicon Circuits

SAN FRANCISCO — In the next decade or so, the circuits etched on silicon-based computer chips are expected to shrink as small as they can physically become, prompting a search for alternative materials to take their place.

Some researchers are putting high hopes on carbon nanotubes, and on Monday a group of researchers at Stanford successfully demonstrated a simple microelectronic circuit composed of 44 transistors fabricated entirely from the threadlike fibers.

The development, which was presented both as a paper and a working demonstration at a technical conference here, is the most striking evidence yet that carbon nanotubes may prove to be the material of the future when today’s silicon-based chips reach their fundamental physical limits.

I.B.M., which is one of the biggest proponents of nanotubes for microelectronic applications, has made clear its hope that carbon nanotube technology will be ready a decade from now, when semiconductors are expected to shrink to minimum dimensions of just 5 nanometers. But until now, researchers at universities and chip makers have succeeded in making only individual devices, like transistors, from carbon nanotubes.

The Stanford development is the first time a complete working circuit has been created and publicly demonstrated, suggesting that the material may indeed live up to its promise.

Silicon, a plentiful natural element which functions both as a conductor and an insulator, has already lasted decades longer than computer engineers originally expected, as generations of increasingly smaller transistors have been perfected. It is used by the computer chip industry to etch circuits much finer than the wave length of light, and engineers and scientists say they believe that the material will continue to scale down, at least until the end of the decade.

But sooner or later the shrinking of circuits made from the material will stop, ending the microelectronic era that has been defined by Moore’s Law, the 1965 observation by the Intel co-founder, Gordon Moore, that the number of transistors that could be placed on a silicon chip doubled at regular intervals.

The Stanford advance seems to hold promise for the belief that whenever the silicon era stalls, the scaling-down process will continue, and permit designers to increase power and capacity of computers far into the future.

The Stanford demonstration came during a session at the International Solid State Circuits Conference, held here annually. A graduate student, Max Shulaker, chose a wooden, human-size hand, connected to a simple motor and gear arrangement on a makeshift stand. Onstage, he threw a switch and the hand shook vigorously.

It was a simple demonstration, but the research group said its goal was to build an entire microprocessor from carbon nanotubes to confirm the potential of the material.

Besides their small size, carbon nanotubes use much less power and switch faster than today’s silicon transistors.

“The bottom line is you can expect an order of magnitude in power saving at the system level,” said Subhasish Mitra, an associate professor of electrical engineering at Stanford and director of the Robust Systems Group. That offers tremendous promise for effectively increasing the battery life in mobile consumer devices in the future, he said.

Other new materials and variations of silicon-based transistors are also being studied to see if they will shrink to smaller sizes. Intel, for example, last year began using a three-dimensional transistor called a FinFET. By turning the device on its side, the chip maker was able to pack transistors more densely on the surface of a chip.

“I’m not saying there is nothing else around,” said H.-S. Philip Wong, a Stanford electrical engineering professor. “It’s just a matter of who wins when you scale down to really, really small dimensions.”

The challenge of carbon nanotubes in their type state is that they form a giant “hairball” of interwoven molecules. However, by chemically growing them on a quartz surface, the researchers are able to align them closely and in regularly spaced rows. They then transfer them to a silicon wafer, where they used conventional photolithographic techniques to make working circuits.

The technological hurdle has been to make reliable circuits even when a small percentage of the wires are misaligned. The Stanford group stated it had perfected a circuit technique that made use of redundancy to work around the imperfectly formed wires.

Dr. Mitra said that “99.5 percent looks very nice on a PowerPoint slide. But when you’re talking about 10 billion things, .5 percent of 10 billion is a really large number, and that completely messes things up.”

Beyond microelectronics, carbon nanotubes are showing promise in commercial applications like rechargeable batteries, bicycle frames, ship hulls, solar cells and water filters, according to an article in the Feb. 1 issue of the journal Science.

As Assad Holds Firm, Obama Could Revisit Arms Policy

Reuters

A member of the Free Syrian Army inside a weapons factory in Aleppo on Monday. President Obama has decided against providing arms to rebels in the past.

WASHINGTON — When President Obama rebuffed four of his top national security officials who wanted to arm the rebels in Syria last fall, it put an end to a months-long debate over how aggressively Washington should respond to the strife there that has now left nearly 70,000 dead.

But the decision also left the White House with no clear strategy to resolve a crisis that has bedeviled it since a popular uprising erupted against President Bashar al-Assad almost two years ago. Despite an American program of nonlethal assistance to opponents of the Syrian government and $365 million in humanitarian aid, Mr. Obama appears to be running out of options to speed Mr. Assad’s exit.

With conditions continuing to deteriorate, officials said, the president could reopen the question of whether to provide weapons to select members of the resistance in an effort to break the impasse in Syria. The question is whether a wary Mr. Obama, surrounded by a new national security team, would come to a different conclusion.

“This is not a closed decision,” a senior administration official insisted. “As the situation evolves, as our confidence increases, we might revisit it.”

Mr. Obama’s refusal to provide arms when the proposal was broached before the November election, officials said, was driven by his reluctance to get drawn into a proxy war and his fear that the weapons would end up in unreliable hands, where they could be used against civilians or Israeli and American interests.

As the United States struggles to formulate a policy, however, Mr. Assad has given no sign that he is ready to yield power, and the Syrian resistance is adamant that it will not negotiate a transition in which he has a role. Mr. Obama, in his State of the Union address, did not repeat his oft-stated confidence that Mr. Assad’s days are numbered.

Even if Mr. Assad was overthrown, the convulsion could fragment Syria along sectarian and ethnic lines, each supported by competing outside powers, said Paul Salem, who runs the Beirut-based Middle East office for the Carnegie Endowment for International Peace. “Syria,” he said, “is in the process, not of transitioning, but disintegrating.”

The State Department has funneled $50 million of nonlethal assistance to the Syrian opposition, including satellite telephones, radios, broadcasting equipment, computers, survival equipment and the training in how to use them. This support, officials say, has helped Syrians opposed to the Assad regime communicate with one another and the outside world, despite efforts by Syrian forces to target rebel communications using Iranian-supplied equipment. A Syria-wide FM radio network is to connect broadcasting operations in several cities in the next several days. The State Department has also helped train local councils in areas that have freed from the Syrian government’s control.

But the State Department does not provide non-lethal assistance to armed rebel factions. This has greatly limited the influence the United States has with armed groups that are likely to control much of Syria if Mr. Assad is ousted.

“The odds are very high that, for better or worse, armed men will determine Syria’s course for the foreseeable future,” said Frederic C. Hof, a former senior State Department official and a senior fellow at the Atlantic Council. “For the U.S. not to have close, supportive relationships with armed elements, carefully vetted, is very risky.”

Because units of the anti-Assad Free Syria Army have captured prisoners and detained criminals in the areas they control, Mr. Hof said, it is essential that either the United States or an ally train rebel staff officers in judicial procedures and make them sensitive to human rights concerns.

While the White House has focused on the risks of providing weapons, other nations have had no such reservations. Russia has continued to provide arms and financial support to the Assad government. Iran has supplied the regime with weapons and Quds Force advisers. Hezbollah has sent militants to Syria to help Mr. Assad’s forces. On the other side of the struggle, anti-government Qaeda-affiliated fighters have been receiving financial and other support from their backers in the Middle East.

The arming plan that was considered last year originated with David H. Petreaus, then the director of the Central Intelligence Agency, and was supported by former Secretary of State Hillary Rodham Clinton. The goal was to create allies in Syria with whom the United States could work during the conflict and if Mr. Assad was removed from power. Each had their reasons for supporting it.

Jerry Buss, Lakers' flamboyant owner, dies at 80

Jerry Buss built a glittering life at the intersection of sports and Hollywood.

After growing up in poverty in Wyoming, he earned success in academia, aerospace and real estate before discovering his favorite vocation when he bought the Los Angeles Lakers in 1979. While Buss wrote the checks and fostered partnerships with two generations of basketball greats, the Lakers won 10 NBA titles and became a glamorous worldwide brand.

With a scientist's analytical skills, a playboy's flair, a businessman's money-making savvy and a die-hard hoops fan's heart, Buss fashioned the Lakers into a remarkable sports entity. They became a nightly happening, often defined by just one word coined by Buss: Showtime.

"His impact is felt worldwide," said Kobe Bryant, who has spent nearly half his life working for Buss.

Buss, who shepherded his NBA team from the Showtime dynasty of the 1980s to the current Bryant era while becoming one of the most important and successful owners in pro sports, died Monday. He was 80.

"Think about the impact that he's had on the game and the decisions he's made, and the brand of basketball he brought here with Showtime and the impact that had on the sport as a whole," Bryant said a few days ago. "Those vibrations were felt to a kid all the way in Italy who was 6 years old, before basketball was even global."

Under Buss' leadership, the Lakers became Southern California's most beloved sports franchise and a worldwide extension of Los Angeles glamour. Buss acquired, nurtured and befriended a staggering array of talented players and basketball minds during his Hall of Fame tenure, from Magic Johnson and Kareem Abdul-Jabbar to Bryant, Shaquille O'Neal and Dwight Howard.

Few owners in sports history can approach Buss' accomplishments with the Lakers, who made the NBA finals 16 times during his nearly 34 years in charge, winning 10 titles between 1980 and 2010. Whatever the Lakers did under Buss' watch, they did it big — with marquee players, eye-popping style and a relentless pursuit of success.

"His incredible commitment and desire to build a championship-caliber team that could sustain success over a long period of time has been unmatched," said Jerry West, Buss' longtime general manager and now a consultant with the Golden State Warriors. "With all of his achievements, Jerry was without a doubt one of the most humble men I've ever been around. His vision was second to none; he wanted an NBA franchise brand that represented the very best and went to every extreme to accomplish his goals."

Buss died at Cedars-Sinai Medical Center in Los Angeles, said Bob Steiner, his assistant and longtime friend. Buss had been hospitalized for most of the past 18 months while undergoing cancer treatment, but the immediate cause of death was kidney failure, Steiner said.

"Anybody associated with the NBA since 1980 benefited greatly from Jerry Buss' impact on the game," Steiner said. "He had a different way of looking at things than I did, and people who had been raised in basketball."

With his condition worsening in recent months, several prominent former Lakers visited Buss to say goodbye. Buss' list of basketball friends is long and stellar, with Johnson citing him as a role model and nearly all former Lakers considering him a friend.

"He was a great man and an incredible friend," Johnson tweeted.

Buss always referred to the Lakers as his extended family, and his players rewarded his fanlike excitement with devotion, friendship and two hands full of championship rings. Working with front-office executives West, Bill Sharman and Mitch Kupchak, Buss spent lavishly to win his titles despite lacking a huge personal fortune, often running the NBA's highest payroll while also paying high-profile coaches Pat Riley and Phil Jackson.

With 1,786 victories, the Lakers easily are the NBA's winningest franchise since he bought the club, which is now run largely by Jim Buss and Jeanie Buss, two of his six children.

"We not only have lost our cherished father, but a beloved man of our community and a person respected by the world basketball community," the Buss family said in a statement issued by the Lakers.

"It was our father's often-stated desire and expectation that the Lakers remain in the Buss family. The Lakers have been our lives as well, and we will honor his wish and do everything in our power to continue his unparalleled legacy."

Johnson and fellow Hall of Famers Abdul-Jabbar and Worthy formed lifelong bonds with Buss during the Lakers' run to five titles in nine years in the 1980s, when the Lakers earned a reputation as basketball's most exciting team with their flamboyant Showtime repartee.

The buzz extended throughout the Forum, where Buss used the Laker Girls, a brass band and promotions to keep Lakers fans interested in all four quarters of their games. Courtside seats, priced at $15 when he bought the Lakers, became the hottest tickets in Hollywood — and they still are, with fixture Jack Nicholson and many other celebrities attending every home game.

Worthy tweeted that Buss was "not only the greatest sports owner, but a true friend & just a really cool guy. Loved him dearly."

After a rough stretch of the 1990s for the Lakers, Jackson led O'Neal and Bryant to a three-peat from 2000-02, rekindling the Lakers' mystique, before Bryant and Pau Gasol won two more titles under Jackson in 2009 and 2010. The Lakers have struggled mightily during their current season despite adding Howard and Steve Nash, and could miss the playoffs for just the third time since Buss bought the franchise.

"Today is a very sad day for all the Lakers and basketball," Gasol tweeted. "All my support and condolences to the Buss family. Rest in peace Dr. Buss."

Always an innovative businessman, Buss paid for the Lakers through both their wild success and his groundbreaking moves to raise revenue. He co-founded a basic-cable sports television network and sold the naming rights to the Forum at times when both now-standard strategies were unusual, further justifying his induction to the Naismith Memorial Basketball Hall of Fame in 2010.

"The NBA has lost a visionary owner whose influence on our league is incalculable and will be felt for decades to come," NBA Commissioner David Stern said. "More importantly, we have lost a dear and valued friend."

Although Buss gained fame and another fortune with the Lakers, he also was a scholar, Renaissance man and bon vivant who epitomized California cool his entire public life.

Buss rarely appeared in public without at least one attractive, much younger woman on his arm — at USC football games, high-stakes poker tournaments, hundreds of boxing matches promoted by Buss at the Forum — and, of course, Lakers games from his private box at Staples Center, which was built under his watch. In failing health recently, Buss hadn't attended a Lakers game in the past two seasons.

After a rough-and-tumble childhood that included stints as a ditch-digger and a bellhop in the frigid Wyoming winters, Buss earned a Ph.D. in chemistry at age 24 and had careers in aerospace and real estate development before getting into sports. With money from his real-estate ventures and a good bit of creative accounting, Buss bought the then-struggling Lakers, the NHL's Los Angeles Kings and both clubs' arena — the Forum — from Jack Kent Cooke in a $67.5 million deal that was the largest sports transaction in history at the time.

Last month, Forbes estimated the Lakers were worth $1 billion, second most in the NBA.

Buss also helped change televised sports by co-founding the Prime Ticket network in 1985, receiving a star on the Hollywood Walk of Fame in 2006 for his work in television. Breaking the contemporary model of subscription services for televised sports, Buss' Prime Ticket put beloved broadcaster Chick Hearn and the Lakers' home games on basic cable.

Buss also sold the naming rights to the Forum in 1988 to Great Western Savings & Loan — another deal that was ahead of its time.

Born in Salt Lake City, Gerald Hatten Buss was raised in poverty in Wyoming before improving his life through education. He also grew to love basketball, describing himself as an "overly competitive but underly endowed player."

After graduating from the University of Wyoming, Buss attended USC for graduate school. He became a chemistry professor and worked as a chemist for the Bureau of Mines before carving out a path to wealth and sports prominence.

The former mathematician's fortune grew out of a $1,000 real-estate investment in a West Los Angeles apartment building with partner Frank Mariani, an aerospace engineer and co-worker.

Heavily leveraging his fortune and various real-estate holdings during two years of negotiations, Buss purchased Cooke's entire Los Angeles sports empire in 1979, including a 13,000-acre ranch in Kern County. Buss cited his love of basketball as the motivation for his purchase, and he immediately worked to transform the Lakers — who had won just one NBA title since moving west from Minneapolis in 1960 — into a star-powered endeavor befitting Hollywood.

"One of the first things I tried to do when I bought the team was to make it an identification for this city, like Motown in Detroit," he told the Los Angeles Times in 2008. "I try to keep that identification alive. I'm a real Angeleno. I want us to be part of the community."

Buss' plans immediately worked: Johnson, Abdul-Jabbar and coach Paul Westhead led the Lakers to the 1980 title. Johnson's ball-handling wizardry and Abdul-Jabbar's smooth inside game made for an attractive style of play, and the Lakers came to define West Coast sophistication.

Riley, the former broadcaster who fit the L.A. image perfectly with his slick-backed hair and good looks, was surprisingly promoted by Buss early in the 1981-82 season after West declined to co-coach the team. Riley became one of the best coaches in NBA history, leading the Lakers to four straight NBA finals and four titles, with Worthy, Michael Cooper, Byron Scott and A.C. Green playing major roles.

Overall, the Lakers made the finals nine times in Buss' first 12 seasons while rekindling the NBA's best rivalry with the Boston Celtics, and Buss basked in the worldwide celebrity he received from his team's achievements. His partying became Hollywood legend, with even his players struggling to keep up with Buss' lifestyle.

Johnson's HIV diagnosis and retirement in 1991 staggered Buss and the Lakers, the owner recalled in 2011. The Lakers struggled through much of the 1990s, going through seven coaches and making just one conference finals appearance in an eight-year stretch despite the 1996 arrivals of O'Neal, who signed with Los Angeles as a free agent, and Bryant, the 17-year-old high schooler acquired in a draft-week trade.

Shaq and Kobe didn't reach their potential until Buss persuaded Jackson, the Chicago Bulls' six-time NBA champion coach, to take over the Lakers in 1999. Los Angeles immediately won the next three NBA titles in brand-new Staples Center, AEG's state-of-the-art downtown arena built with the Lakers as the primary tenant.

After the Lakers traded O'Neal in 2004, they hovered in mediocrity again until acquiring Gasol in a heist of a trade with Memphis in early 2008. Los Angeles made the next three NBA finals, winning two more titles.

Through the Lakers' frequent successes and occasional struggles, Buss never stopped living his Hollywood dream. He was an avid poker player and a fixture on the Los Angeles club scene well into his 70s, when a late-night drunk-driving arrest in 2007 — with a 23-year-old woman in the passenger seat of his Mercedes-Benz — prompted him to cut down on his partying.

Buss owned the NHL's Kings from 1979-87, and the WNBA's Los Angeles Sparks won two league titles under Buss' ownership. He also owned Los Angeles franchises in World Team Tennis and the Major Indoor Soccer League.

Ownership of the Lakers is now in a trust controlled by Buss' six children, who all have worked for the Lakers organization in various capacities for several years. Jim Buss, the Lakers' executive vice president of player personnel and the second-oldest child, has taken over much of the club's primary decision-making responsibilities in the last few years, while daughter Jeanie runs the franchise's business side.

"I am blessed with a wonderful family who have helped me and guided me every step of the way," Buss said in 2010 at his Hall of Fame induction ceremony. "This support is the best anybody could ever have."

Jerry Buss still served two terms as president of the NBA's Board of Governors and was actively involved in the 2011 lockout negotiations, developing blood clots in his legs attributed to his extensive travel during that time.

Buss is survived by his six children: sons Johnny, Jim, Joey and Jesse, and daughters Jeanie Buss and Janie Drexel. He had eight grandchildren.

Arrangements are pending for a funeral and memorial service, likely at Staples Center or a nearby theatre in downtown Los Angeles.

Personal Health: Health Effects of Smoking for Women

The title of a recent report on smoking and health might well have paraphrased the popular ad campaign for Virginia Slims, introduced in 1968 by Philip Morris and aimed at young professional women: “You’ve come a long way, baby.”

Today that slogan should include: “. . . toward a shorter life.” Ten years shorter, in fact.

The new report is one of two rather shocking analyses of the hazards of smoking and the benefits of quitting published last month in The New England Journal of Medicine. The data show that “women who smoke like men die like men who smoke,” Dr. Steven A. Schroeder, a professor of health and health care at the University of California, San Francisco, wrote in an accompanying editorial.

That was not always the case. Half a century ago, the risk of death from lung cancer among men who smoked was five times higher than that among women smokers. But by the first decade of this century, that risk had equalized: for both men and women who smoked, the risk of death from lung cancer was 25 times greater than for nonsmokers, Dr. Michael J. Thun of the American Cancer Society and his colleagues reported.

Today, women who smoke are even more likely than men who smoke to die of lung cancer. According to a second study in the same journal, women smokers face a 17.8 times greater risk of dying of lung cancer, than women who do not smoke; men who smoke are at 14.6 times greater risk to die of lung cancer than men who don’t. Women who smoke now face a risk of death from lung cancer that is 50 percent higher than the estimates reported in the 1980s, according to Dr. Prabhat Jha of the Center for Global Health Research in Toronto and his colleagues.

After controlling for age, body weight, education level and alcohol use, the new analysis found something else: men and women who continue to smoke die on average more than 10 years sooner than those who never smoked.

Dramatic progress has been made in reducing the prevalence of smoking, which has fallen in the United States from 42 percent of adults in 1965 (the year after the first surgeon general’s report on smoking and health) to 19 percent in 2010. Yet smoking still results in nearly 200,000 deaths a year among people 35 to 69 years old in this country. A quarter of all deaths in this age group would not occur if smokers had the same risk of death as nonsmokers.

The risks are even greater among men 55 to 74 and women 60 to 74. More than two-thirds of all deaths among current smokers in these age groups are related to smoking. Over all, the death rate from all causes combined in these age groups “is now at least three times as high among current smokers as among those who have never smoked,” Dr. Thun’s team found.

While lung cancer is the most infamous hazard linked to smoking, the habit also raises the risk of death from heart disease, stroke, pulmonary disease and other cancers, including breast cancer.

Furthermore, changes in how cigarettes are manufactured may have increased the dangers of smoking. The use of perforated filters, tobacco blends that are less irritating, and paper that is more porous made it easier to inhale smoke and encouraged deeper inhalation to achieve satisfying blood levels of nicotine.

The result of deeper inhalation, Dr. Thun’s report suggests, has been an increased risk of chronic obstructive pulmonary disease, or C.O.P.D., and a shift in the kind of lung cancer linked to smoking. Among nonsmokers, the risk of death from C.O.P.D. has declined by 45 percent in men and has remained stable in women, but the death rate has more than doubled among smokers.

But there is good news, too: it’s never too late to reap the benefits of quitting. The younger you are when you stop smoking, the greater your chances of living a long and healthy life, according to the findings of Dr. Jha’s international team.

The team analyzed smoking and smoking-cessation histories of 113,752 women and 88,496 men 25 and older and linked them to causes of deaths in these groups through 2006.

Those who quit smoking by age 34 lived 10 years longer on average than those who continued to smoke, giving them a life expectancy comparable to people who never smoked. Smokers who quit between ages 35 and 44 lived nine years longer, and those who quit between 45 and 54 lived six years longer. Even quitting smoking between ages 55 and 64 resulted in a four-year gain in life expectancy.

The researchers emphasized, however, that the numbers do not mean it is safe to smoke until age 40 and then stop. Former smokers who quit by 40 still experienced a 20 percent greater risk of death than nonsmokers. About one in six former smokers who died before the age of 80 would not have died so young if he or she had never smoked, they reported.

Dr. Schroeder believes we can do a lot better to reduce the prevalence of smoking with the tools currently in hand if government agencies, medical insurers and the public cooperate.

Unlike the races, ribbons and fund-raisers for breast cancer, “there’s no public face for lung cancer, even though it kills more women than breast cancer does,” Dr. Schroeder said in an interview. Lung cancer is stigmatized as a disease people bring on themselves, even though many older victims were hooked on nicotine in the 1940s and 1950s, when little was known about the hazards of smoking and doctors appeared in ads assuring the public it was safe to smoke.

Raising taxes on cigarettes can help. The states with the highest prevalence of smoking have the lowest tax rates on cigarettes, Dr. Schroeder said. Also helpful would be prohibiting smoking in more public places like parks and beaches. Some states have criminalized smoking in cars when children are present.

More “countermarketing” of cigarettes is needed, he said, including antismoking public service ads on television and dramatic health warnings on cigarette packs, as is now done in Australia. But two American courts have ruled that the proposed label warnings infringed on the tobacco industry’s right to free speech.

Health insurers, both private and government, could broaden their coverage of stop-smoking aids and better publicize telephone quit lines, and doctors “should do more to stimulate quit attempts,” Dr. Schroeder said.

As Nicola Roxon, a former Australian health minister, put it, “We are killing people by not acting.”

DealBook: Reader's Digest Files for Bankruptcy, Again

Executives at Reader’s Digest must be hoping that the magazine’s second trip to bankruptcy court in under four years will be its last.

The magazine’s parent, RDA Holding, filed for Chapter 11 protection late on Sunday in another effort to cut down the debt that has plagued the pocket-size publication for years. The company is hoping to convert about $465 million of its debt into equity held by its creditors.

In a court filing, Reader’s Digest said it held about $1.1 billion in assets and just under $1.2 billion in debt. It has provisionally lined up about $105 million in financing to keep it afloat during the Chapter 11 case.

This week’s filing is the latest effort by the 91-year-old publisher, whose magazine once resided on many American coffee tables, to fix itself in a difficult economic environment.

“After considering a wide range of alternatives, we believe this course of action will most effectively enable us to maintain our momentum in transforming the business and allow us to capitalize on the growing strength and presence of our outstanding brands and products,” Robert E. Guth, the company’s chief executive, said in a statement.

Reader’s Digest last filed for bankruptcy in 2009, emerging a year later under the control of lenders like JPMorgan Chase.

That reorganization substantially cut the publisher’s debt, and afterward the company worked to further shrink its footprint. It jettisoned nonessential publications in a series of deals, including the $180 million sale of Allrecipes.com and the $4.3 million sale of Every Day With Rachael Ray, both to the Meredith Corporation.

Most of the money from those transactions went to pay down a still significant debt burden. But the company remained pressured by what it described in a court filing as steep declines that still bedevil the media industry. Last year, the publisher began negotiating with its lenders, including Wells Fargo, about amending some of its debt obligations. That process eventually led to a “pre-negotiated agreement” with creditors, which will be put into effect by the bankruptcy filing.

This time, Reader’s Digest is hoping to spend even less time in court. Mr. Guth said in a court filing that the publisher aims to emerge from bankruptcy protection in about four months.

The company’s biggest unsecured creditors include firms represented by Luxor Capital. The Federal Trade Commission also contends that it is owed $8.8 million in a settlement claim.

Reader’s Digest is being advised by Evercore Partners and the law firm Weil, Gotshal & Manges.

Death Toll Grows in Pakistan Explosion

Agence France-Presse — Getty Images

A bomb killed scores of people on Saturday at a market in Quetta, Pakistan, in a Shiite minority neighborhood.

ISLAMABAD, Pakistan — Hundreds of Shiite women staged a sit-in in the western city of Quetta on Sunday evening to mourn the 84 people who were killed in an explosion a day earlier in a crowded market there, and they demanded that the government arrest the attackers.

Grieving relatives declined to bury their dead until the government promised to track down those responsible for carrying out brazen attacks against Hazaras, a Shiite ethnic minority, in the city.

Government officials said a team, led by a high-ranking police official, was investigating.

Protests and sit-ins were also held in other major cities on Sunday, as Shiite leaders condemned the government’s inability of the government to curb the killings.

The attack on Saturday took place in Hazara Town, one of two enclaves in Quetta for Hazaras, who have suffered numerous attacks at the hands of Sunni death squads in recent years.

The police said that explosives were hidden in a water-supply truck. It remained unclear how the truck had managed to enter the busy market, avoiding detection by police and intelligence specialists. The police said the bomb was apparently set off by a remote-controlled device, possibly hidden in a rickshaw. The explosion caused a building to collapse, and three other structures were heavily damaged.

Shiite leaders have also called for a strike in Karachi, the southern port city, on Monday. The Muttahida Qaumi Movement, Karachi’s most powerful political party, said it would support a strike.

The growing sense of insecurity and vulnerability felt by Shiites was evident in angry speeches by leaders across the country on Sunday.

Allama Asghar Askari, a Shiite leader, sharply criticized the country’s law enforcement authorities at a rally here in the nation’s capital. “If the law-enforcement forces had targeted the militant strongholds with real intent, people would not have seen such a day,” Mr. Askari said to hundreds of protesters. One was holding up a placard that said “Stop Shiite genocide.”

Some Shiites have suggested that Army troops should be sent to Quetta to quell the sectarian violence, but for now neither the government nor the military has given any indication of a deployment.

The police in Quetta and the Frontier Corps, a provincial paramilitary force, have come under heavy criticism as violence has escalated and militants belonging to Lashkar-e-Jhangvi, the largest sectarian group, have targeted Shiites with impunity in Baluchistan Province, where Quetta is the capital.

“Militants term Hazaras as ‘impure’ and have vowed to ‘cleanse Quetta of their presence,’ ” Tahir Hussain, the city’s representative for the Human Rights Commission of Pakistan, said in an interview.

The killings have forced at least 20,000 Hazaras to leave the city, Mr. Hussain said, adding that militants have a heavy presence in the Mastung district of Baluchistan Province. More than 300 Shiites, many of them Hazaras, have been killed in Baluchistan since 2008, according to Human Rights Watch.

The Frontier Corps and the police have shown little willingness to clamp down on militant strongholds in Mastung, Mr. Hussain said.

“They know who are the perpetrators,” he said. “But apart from giving empty assurances, the high-ups of law-enforcement have not done anything.”

Danica Patrick wins pole for NASCAR's Daytona 500

DAYTONA BEACH, Fla. (AP) — Danica Patrick has made history before — as a woman and a racer, in Indianapolis and Japan.

The spotlight is nothing new. But never has it been this bright before.

Patrick won the Daytona 500 pole Sunday, becoming the first woman to secure the top spot for any race in NASCAR's premier circuit. It's by far the biggest achievement of her stock-car career.

"I was brought up to be the fastest driver, not the fastest girl," she said. "That was instilled in me from very young, from the beginning. Then I feel like thriving in those moments, where the pressure's on, has also been a help for me. I also feel like I've been lucky in my career to be with good teams and have good people around me. I don't think any of it would have been possible without that.

"For those reasons, I've been lucky enough to make history, be the first woman to do many things. I really just hope that I don't stop doing that. We have a lot more history to make. We are excited to do it."

Her latest stamp in the history books came with a lap at 196.434 mph around Daytona International Speedway. Patrick went out eighth in the qualifying session, then had to wait about two hours as 37 fellow drivers tried to take her spot.

Only four-time Cup champion Jeff Gordon even came close to knocking her off. Gordon was the only other driver who topped 196 mph in qualifying. He locked up the other guaranteed spot in next week's season-opening Daytona 500.

"It's great to be a part of history with Danica being on the pole," said Gordon, who joked that at least he was the fastest guy. "I think we all know how popular she is, what this will do for our sport. Congratulations to her. Proud to be on there with her."

The rest of the field will be set in duel qualifying races Thursday.

However the lineup unfolds, all drivers will line up behind Patrick's No. 10 Chevrolet SS.

And she knows her latest achievement will mean more public relations work.

The routine is nothing new for Patrick, who was the first woman to lead laps in the Indianapolis 500. She finished third in 2009, the highest finish in that illustrious race for a woman. And she became the only woman to win an IndyCar race when she did it in Japan in 2008.

Hardly anyone witnessed that victory.

Leading the field to the green flag in NASCAR's showcase event should be must-watch television.

"That's a huge accomplishment," team owner and fellow driver Tony Stewart said. "It's not like it's been 15 or 20 years she's been trying to do this. It's her second trip to Daytona here in a Cup car. She's made history in the sport. That's stuff that we're proud of being a part of with her. It's something she should have a huge amount of pride in.

"It's never been done. There's only one person that can be the first to do anything. Doesn't matter how many do it after you do, accomplish that same goal. The first one that does always has that little bit more significance to it because you were the first."

Even before her fast lap Sunday, Patrick was the talk of Speedweeks. Not only did she open up about her budding romance with fellow Sprint Cup rookie Ricky Stenhouse Jr., but she was considered the front-runner for the pole after leading practice sessions Saturday.

And she didn't disappoint.

She kept her car at or near the bottom of the famed track and gained ground on the straightaways, showing lots of power from a Hendrick Motorsports engine.

"It's easy to come down here in your first or second year as a driver and clip the apron trying to run too tight a line or do something and scrub speed off," Stewart said. "That's something she did an awesome job. Watching her lap, she runs so smooth. ... She did her job behind the wheel, for sure."

The result surely felt good for Patrick, especially considering the former IndyCar driver has mostly struggled in three NASCAR seasons. Her best finish in 10 Cup races is 17th, and she has one top-five in 58 starts in the second-tier Nationwide Series.

She raced part-time in 2010 and 2011 while still driving a full IndyCar slate. She switched solely to stock cars last season and finished 10th in the Nationwide standings.

She made the jump to Sprint Cup this season and will battle Stenhouse for Rookie of the Year honors.

Starting out front in an unpredictable, 500-mile race doesn't guarantee any sort of result, but securing the pole will put her in the limelight for at least the rest of the week.

She also won the pole at Daytona for last year's Nationwide race.

This is considerably bigger.

The previous highest female qualifier in a Cup race was Janet Guthrie. She started ninth at Bristol and Talladega in 1977.

"It's obviously a history-making event that will last a long, long time," Guthrie said, praising Patrick's feat. "It's a different era, of course. Different times. I can't imagine what I would do with a spotter or somebody telling me how to drive. It's rather a different sport now. Back then, there was a much greater difference from the front of the field to the back."

Guthrie received a lukewarm reception from fellow drivers back then.

Patrick was much more welcomed, undoubtedly because of her background and popularity.

She's comfortable being in the spotlight, evidenced by her racing career, her television commercials and her sudden openness about her personal life.

"I think when pressure's on and when the spotlight's on, I feel like it ultimately ends up becoming some of my better moments and my better races and better results," Patrick said. "I just understand that if you put the hard work in before you go out there that you can have a little peace and a little peace of mind knowing that you've done everything you can and just let it happen."

Cuomo Bucks Tide With Bill to Lift Abortion Limits

ALBANY — Bucking a trend in which states have been seeking to restrict abortion, Gov. Andrew M. Cuomo is putting the finishing touches on legislation that would guarantee women in New York the right to late-term abortions when their health is in danger or the fetus is not viable.

Mr. Cuomo, seeking to deliver on a promise he made in his recent State of the State address, would rewrite a law that currently allows abortions after 24 weeks of pregnancy only if the pregnant woman’s life is at risk. The law is not enforced, because it is superseded by federal court rulings that allow late-term abortions to protect a woman’s health, even if her life is not in jeopardy. But abortion rights advocates say the existence of the more restrictive state law has a chilling effect on some doctors and prompts some women to leave the state for late-term abortions.

Mr. Cuomo’s proposal, which has not yet been made public, would also clarify that licensed health care practitioners, and not only physicians, can perform abortions. It would remove abortion from the state’s penal law and regulate it through the state’s public health law.

Abortion rights advocates have welcomed Mr. Cuomo’s plan, which he outlined in general terms as part of a broader package of women’s rights initiatives in his State of the State address in January. But the Roman Catholic Church and anti-abortion groups are dismayed; opponents have labeled the legislation the Abortion Expansion Act.

The prospects for Mr. Cuomo’s effort are uncertain. The State Assembly is controlled by Democrats who support abortion rights; the Senate is more difficult to predict because this year it is controlled by a coalition of Republicans who have tended to oppose new abortion rights laws and breakaway Democrats who support abortion rights.

New York legalized abortion in 1970, three years before it was legalized nationally by the Supreme Court in Roe v. Wade. Mr. Cuomo’s proposal would update the state law so that it could stand alone if the broader federal standard set by Roe were to be undone.

“Why are we doing this? The Supreme Court could change,” said a senior Cuomo administration official, who spoke on the condition of anonymity because the governor had not formally introduced his proposal.

But opponents of abortion rights, already upset at the high rate of abortions in New York State, worry that rewriting the abortion law would encourage an even greater number of abortions. For example, they suggest that the provision to allow abortions late in a woman’s pregnancy for health reasons could be used as a loophole to allow unchecked late-term abortions.

“I am hard pressed to think of a piece of legislation that is less needed or more harmful than this one,” the archbishop of New York, Cardinal Timothy M. Dolan, wrote in a letter to Mr. Cuomo last month. Referring to Albany lawmakers in a subsequent column, he added, “It’s as though, in their minds, our state motto, ‘Excelsior’ (‘Ever Upward’), applies to the abortion rate.”

National abortion rights groups have sought for years to persuade state legislatures to adopt laws guaranteeing abortion rights as a backup to Roe. But they have had limited success: Only seven states have such measures in place, including California, Connecticut and Maryland; the most recent state to adopt such a law is Hawaii, which did so in 2006.

“Pretty much all of the energy, all of the momentum, has been to restrict abortion, which makes what could potentially happen in New York so interesting,” said Elizabeth Nash, state issues manager at the Guttmacher Institute, a research group that supports abortion rights. “There’s no other state that’s even contemplating this right now.”

In most statehouses, the push by lawmakers has been in the opposite direction. The past two years has seen more provisions adopted at the state level to restrict abortion rights than in any two-year period in decades, according to the Guttmacher Institute; last year, 19 states adopted 43 new provisions restricting abortion access, while not a single significant measure was adopted to expand access to abortion or to comprehensive sex education.

“It’s an extraordinary moment in terms of the degree to which there is government interference in a woman’s ability to make these basic health care decisions,” said Andrea Miller, the president of NARAL Pro-Choice New York. “For New York to be able to send a signal, a hopeful sign, a sense of the turning of the tide, we think is really important.”

Abortion rights advocates say that even though the Roe decision supersedes state law, some doctors are hesitant to perform late-term abortions when a woman’s health is at risk because the criminal statutes remain on the books.

“Doctors and hospitals shouldn’t be reading criminal laws to determine what types of health services they can offer and provide to their patients,” said M. Tracey Brooks, the president of Family Planning Advocates of New York State.

For Mr. Cuomo, the debate over passing a new abortion law presents an opportunity to appeal to women as well as to liberals, who have sought action in Albany without success since Eliot Spitzer made a similar proposal when he was governor. But it also poses a challenge to the coalition of Republicans and a few Democrats that controls the State Senate, the chamber that has in the past stood as the primary obstacle to passing abortion legislation in the capital.

The governor has said that his Reproductive Health Act would be one plank of a 10-part Women’s Equality Act that also would include equal pay and anti-discrimination provisions. Conservative groups, still stinging from the willingness of Republican lawmakers to go along with Mr. Cuomo’s push to legalize same-sex marriage in 2011, are mobilizing against the proposal. Seven thousand New Yorkers who oppose the measure have sent messages to Mr. Cuomo and legislators via the Web site of the New York State Catholic Conference.

A number of anti-abortion groups have also formed a coalition called New Yorkers for Life, which is seeking to rally opposition to the governor’s proposal using social media.

“If you ask anyone on the street, ‘Is there enough abortion in New York?’ no one in their right mind would say we need more abortion,” said the Rev. Jason J. McGuire, the executive director of New Yorkers for Constitutional Freedoms, which is part of the coalition.

Members of both parties say that the issue of reproductive rights was a significant one in November’s legislative elections. Democrats, who were bolstered by an independent expenditure campaign by NARAL, credit their victories in several key Senate races in part to their pledge to fight for legislation similar to what Mr. Cuomo is planning to propose.

Republicans, who make up most of the coalition that controls the Senate, have generally opposed new abortion rights measures. Speaking with reporters recently, the leader of the Republicans, Dean G. Skelos of Long Island, strenuously objected to rewriting the state’s abortion laws, especially in a manner similar to what the governor is seeking.

“You could have an abortion up until the day the child would be born, and I think that’s just wrong,” Mr. Skelos said. He suggested that the entire debate was unnecessary, noting that abortion is legal in New York State and saying that is “not going to be changed.”

The Senate Democratic leader, Andrea Stewart-Cousins of Yonkers, who is the sponsor of a bill that is similar to the legislation the governor is drafting, said she was optimistic that an abortion measure would reach the Senate floor this year.

“New York State’s abortion laws were passed in 1970 in a bipartisan fashion,” she said. “It would be a sad commentary that over 40 years later we could not manage to do the same thing.”

S.E.C. Inquiry Into China Film Trade Unnerves Hollywood

LOS ANGELES — Hunkered down. Lawyered up. Looking over your shoulder for the prosecutors.

That is a not a comfortable way to do business. But it may become business as usual for those who have been struggling to make China both a customer for Hollywood films and a partner in the production of them.

Last March, word reached several studios of a confidential inquiry by the Securities and Exchange Commission and the Justice Department into possible violations of the Foreign Corrupt Practices Act by people or companies involved in the China film trade. Since then, executives and their advisers have been waiting for some public sign of the scope or focus of the government’s interest.

So far, there has been none.

But official silence has not kept the investigation from casting a chill over dealings between Hollywood and China. At a discussion in August sponsored by the Beverly Hills Bar Association, some panel members said deal-making had been complicated by the investigation. This concern was repeated in recent interviews by people involved in the Chinese-American film trade, though only on the condition of anonymity to avoid attracting the attention of regulators.

The legal concern is arising precisely as Chinese consumers — once presumed to be an easy audience for American-made films like “Skyfall” or “The Dark Knight Rises” — have been showing a preference for homegrown, Chinese-language blockbusters.

Those include the comedy “Lost in Thailand,” which surpassed American films to collect more than $200 million in China’s theaters after it opened last year, and the action-fantasy “Journey to the West: Conquering the Demons,” which had sales of $50 million in its first four days this month, according to the China Film Biz blog.

Asked last week about the corrupt practices inquiry, spokesmen for the Justice Department and the Securities and Exchange Commission declined to comment. All the major studios, in addition to DreamWorks Animation and Marvel Entertainment, which have extensive dealings in China, either did not respond or declined to comment.

Last April, people briefed on the inquiry said virtually every Hollywood company with significant dealings in China had been notified in prior weeks of the inquiry into possible violations of the Foreign Corrupt Practices Act, which forbids American companies from making illegal payments to government officials or others to ease the way for operations abroad.

Last week, a government official close to the inquiry, who spoke on the condition of anonymity in order not to prejudice the investigation, said the inquiry was continuing.

Bethany L. Hengsbach, a lawyer in Los Angeles versed in China dealings, said last week that she could not discuss the action because she had been retained by an involved party.

At the Beverly Hills Bar Association panel in August, Ms. Hengsbach spoke publicly of indications that federal officials were involved in “an industry sweep of the studios,” while warning that it was rare for such investigations “to turn up nothing.”

In the meantime, business has moved forward on projects like “Kung Fu Panda 3,” a Chinese coproduction from DreamWorks Animation, and “Iron Man 3,” which Marvel, a Walt Disney Company unit, has shot partly in China.

Thomas E. McLain, the chairman of the Asia Society Southern California, said he had not seen evidence that deals were being put on the back burner until the inquiry was resolved. But he acknowledged that the investigation was a topic of conversation at the society’s annual U.S.-China Film Summit. The event was held here last October, and drew some important figures from the Chinese film industry, including Han Sanping, the chairman of the China Film Group.

To keep Washington focused less on fears of corruption than on the possible benefits of film trade with China — where the growing box office reached $2.7 billion last year — the U.S.-Asia Institute, a policy-oriented nonprofit, has begun including movie operations among the stops made by lawmakers and their staff on institute-sponsored trips to China.

Kent A. Lucken, the institute’s president, said in an interview last week, “They need to see that there are American companies operating in China, fully regulated and under the law, conducting business, and thriving.”

Some who are involved in Hollywood’s entry into China are privately expressing hope that the Justice Department inquiry will be resolved before they run out of time on what one of them last week called a “ticking clock,” as Chinese consumers outgrow their receptivity to Hollywood fare.

The squeeze started last year when they began to spend more money on some homegrown films than on the American blockbusters.

But Michael W. Emmick, who was formerly a prosecutor with the Justice Department, and now focuses on the corrupt practices cases, among other things, in his private law practice, said a resolution could be a long time coming.

“This is still early in the game,” he said.

While Mr. Emmick is not representing clients in the investigation, and said he had no direct knowledge of it, he said that regulators sometimes use such industrywide inquiries as a “cost effective” way of putting an entire business sector — like the pharmaceuticals industry or the portion of the financial industry dealing in sovereign debt — on notice.

“Sometimes, they’re trying to send a message, to make companies keep their records, beyond the usual document retention policy,” Mr. Emmick said. He cautioned against characterizing the Hollywood action as a “sweep,” which he said might indicate imminent civil suits or arrests.

In a summary published this month, lawyers for the WilmerHale law firm said that new foreign corrupt practices enforcement cases by the S.E.C. and the Justice Department declined to just 27 last year, after spiking to a recent high of 90 in 2010, though violations of the act remain a stated priority for both agencies.

Looking ahead at the rest of the year, the lawyers predicted the “continuation and outcome” of industrywide government examinations of “financial institutions’ dealings with sovereign wealth funds, movie studios’ operations in China, and oil and gas companies’ business in Libya.”

Asked to elaborate on his expectations for the film industry investigation, Roger M. Witten, one of the authors of the report, in an e-mail last week echoed what those hunkered-down studio representatives have been saying for the last year.

“Unfortunately, I’m not in a position to talk about this on or off the record,” he said.

Brooks Barnes contributed reporting from Los Angeles, and Edward Wyatt from Washington.

Karzai to Forbid His Forces to Request Foreign Airstrikes

KABUL, Afghanistan — President Hamid Karzai said Saturday that he would issue a decree forbidding his military forces from turning to NATO or American forces to conduct airstrikes, and he condemned the use of torture on detainees by his security forces.

He made his comments in a speech at the Afghan National Military Academy in Kabul. It was the first time he had dwelt at such length and with such passion on human rights.

His proposed ban on Afghan troops from calling in airstrikes came after a joint Afghan-NATO attack last week in Kunar Province, in eastern Afghanistan, that killed four women, one man and five children, all of them civilians, according to local officials.

Mr. Karzai said Gen. Joseph F. Dunford Jr., the commander of the international coalition forces fighting the Taliban and other insurgents in Afghanistan, told him that the airstrike had been requested by the National Directorate of Security, the country’s intelligence service. The attack took place in the Shigal district, an area where two known Taliban commanders were visiting family members, Afghan officials have said.

“Our N.D.S. in their own country calls foreigners to assist them and bombard four or five Al Qaeda or Taliban,” Mr. Karzai said.

“It is very regrettable to hear this,” he added. “You are representing Afghan pride. How do you call for an airstrike from foreigners on your people?”

Civilian casualties in the war on the Taliban has long vexed Mr. Karzai and has been a major point of contention with American and NATO troops. New rules instituted by commanders from the International Security Assistance Force have minimized the loss of life, and the coalition has all but stopped air attacks on populated areas and on homes. The result has been a dramatic drop in civilian casualties caused by foreign forces.

Nevertheless, Afghan troops, who lack their own air support, still turn to foreign forces for help during pitched battles with the Taliban and other insurgents. It was not clear whether there would be exceptions to Mr. Karzai’s decree, but he was clearly dismayed that his own forces would be employing the very techniques he had worked so hard to persuade the West to abandon.

In an unusual move, the Afghan president also publicly acknowledged that torture was a problem in Afghan detention centers and pledged to halt it. In the past, the government has largely deflected charges of torture raised by human rights organizations, contending that any abuse was the work of a few bad actors.

But after a United Nations report released in January detailed abuses or torture at a number of detention sites around the country, Mr. Karzai took a closer and more independent look at the complaints.

He appointed a delegation to investigate the report’s validity, and when the inquiry confirmed many of the allegations, he ordered the security ministries to implement the team’s recommendations. He reiterated that order on Saturday. The recommendations include prosecuting perpetrators of torture, giving detainees access to defense lawyers, providing medical treatment for detainees who are ill or have been beaten, and videotaping all interrogations.

“Not only have foreigners tormented and punished Afghans, but our people have been terrorized and punished by our own sons too,” Mr. Karzai said. “The U.N. report showed that even after 10 years, our people are tortured and mistreated in prisons.”

The United Nations’ human rights office here emphasized the importance of Mr. Karzai’s attention to the issue.

“It is encouraging that the president appears to be personally taking the issue of human rights of all Afghans seriously,” said Georgette Gagnon, the office’s director of human rights. She added that the government should act immediately on the delegation’s recommendations. “We urge them to do so without delay,” she said.
