State of the Art: Reviewing All-in-One Luxury PCs From Vizio, H.P. and Apple - State of the Art

Try this simple test at home: What’s the name of Dell’s best-selling PC? Anybody? Anybody?

Right. Nobody knows.

And nobody cares. Today, it’s all about phones and tablets, baby. Nobody buzzes about the PC anymore. Innovation is dead. Sales are down, right?

Actually, there’s one pocket of surging sales and innovation in PC land: the luxury all-in-one computer, of the type made famous by the iMac.

I took a look at three silver, high-design, screen-on-a-stalk competitors: Apple’s new iMac ($1,300 and up), Hewlett-Packard’s SpectreOne ($1,300 and up), and the Vizio All-in-One Touch PC ($1,000 and up). (Lenovo, Dell, Samsung and Acer also offer, or soon will offer, very similar all-in-ones.)

What characterizes these computers? First, a tremendous emphasis on looks. They’re shiny, sleek, futuristic, uncluttered and cordless (they come with Bluetooth wireless keyboard and trackpad or mouse). They’re sculpture. In your kitchen or on your desk, they contribute to the décor even when they’re turned off.

The usual box of innards is missing. In the iMac, the guts are concealed behind the screen. In the Vizio, they’re in the foot of the monitor. In the H.P., they’re inside the stalk that supports the screen.

The second common trait is state-of-the-art components. These computers offer gorgeous, vivid, high-definition screens. And they’re fast; they’re powered by the latest Intel chips and lots of memory.

Third characteristic: no DVD drive.

What? Do these companies really think that the era of the disc is over? That nobody will ever again want to digitize music from a CD? Or burn some files to a disc to hand to a colleague? Or borrow a DVD from the library?

Apple, H.P. and Vizio seem to believe that everything is online now. Well, it’s not. Want to rent an Indiana Jones movie, “Jurassic Park” or “Schindler’s List”? How about “Star Wars,” “A Beautiful Mind,” “Bridget Jones’s Diary,” or “My Big Fat Greek Wedding”? Too bad; they’re not available to rent online.

You can, of course, buy an external DVD drive. But aren’t these called “all in ones”? An external drive just looks stupid.

Now, on a laptop, eliminating the DVD drive is understandable. You carry laptops. Weight matters. Bulk matters. But why eliminate DVD drives on computers that stay in one place?

All right, end of rant.

The new iMac, clad in its traditional aluminum, is stunning. The stand is still a thin, curved L of metal — but now, the screen appears to be just as thin (0. 2 inches). Where are the guts?

Turns out it’s a trick — an illusion. Behind the screen, you see a substantial bulge; Apple tapered the aluminum as it approaches the screen, so that from front angles it seems that the whole screen is razor thin.

Apple has also eliminated much of the glare that has long dogged today’s glossy screens. Viewed side-by-side with its rivals, the iMac is a lot less reflective.

There are two iMac sizes: 21.5 and 27 inches. The $1,300 and $1,800 base models come with a 1-terabyte hard drive, 8 gigabytes of memory and an i5 Intel processor. Each has four USB 3.0 jacks, two Thunderbolt jacks (for video input or output or external hard drives), and camera memory-card slot, awkwardly positioned on the back. Apple has ditched the FireWire jack it spent so many years promoting.

On the 21.5-incher, you can’t upgrade the memory yourself; what you buy is what you’ll have forever, unless you take it into the shop.

On the 27-inch model, you can install as much as 32 gigabytes yourself, through an easily opened door. (That, for the record, is about 262,144 times the memory as the original Macintosh.) Online, you can order your iMac with a 3-terabyte hard drive, 32 gigabytes of memory, a 768-gigabyte flash-memory drive and a $3,700 invoice.

Vizio isn’t a company you expect to be in the PC business; it made its mark selling high-quality, low-price TV sets. And sure enough, by far the best part of the All-in-One Touch PC is its lovely touch screen, available in 24- and 27-inch versions. .

A nontouch version is also available, but the Vizio comes with Windows 8, which is far more pleasant to use with a touch screen.

Chancellor Angela Merkel of Germany Opens Campaign for a Third Term

BERLIN — Angela Merkel began her campaign for re-election on Tuesday with a display of the down-to-earth pragmatism that has helped make her immensely popular among Germans and well positioned to win a third term as chancellor next year.

Wielding two bouquets of bright orange flowers after delegates in her center-right Christian Democratic Union elected her to a seventh term as their party leader with a record 97.9 percent of the votes, Ms. Merkel took the podium and thanked the cheering crowd.

“Those who know me know that I’m overwhelmed and touched,” she said. “And now, let’s get to work. We have a lot to do.”

With overall approval ratings close to 70 percent, Ms. Merkel, a 58-year-old daughter of a Lutheran pastor who grew up in East Germany, is viewed as being at the height of her powers. Surveys show her comfortably ahead of her closest rival, Peer Steinbrück of the center-left Social Democrats, before parliamentary elections next September.

Analysts point to her combination of pragmatism and readiness to compromise the driving force behind her popularity. Nils Diederich, a professor of political science at the Free University of Berlin, said Ms. Merkel had succeeded in shifting her party away from its traditionalist ideology, making it more attractive to mainstream Germans. In addition, she has shepherded her country through Europe’s worst economic crisis in recent history and into a leadership role.

“During Ms. Merkel’s tenure, she has led Germany into a position of greater strength than it has ever known,” Mr. Diederich said. “Ms. Merkel has shown people that we have nothing to hide.”

That confidence was on display in the chancellor’s speech to delegates, who gathered on Tuesday for a two-day congress in the central city of Hanover. She praised her government as the country’s most successful since its postwar reunification in 1990, despite the challenges it faces.

“These are turbulent times, and sometimes we find ourselves in stormy waters,” Ms. Merkel said. She went on to highlight her government’s successes, including low unemployment and economic stability in the face of the economic crisis crippling much of the rest of Europe.

“In such times, no other government could lead the country as successfully as our conservative-liberal coalition,” Ms. Merkel told members.

In spite of the fact that the chancellor is personally popular, her government — an alliance of her own conservative Christian Democratic Union with the sister party for the state of Bavaria, the Christian Social Union, and the pro-business Free Democrats — is not.

Recent months have seen the Free Democrats bleeding support, opening the discussion for other possible alliances, with a so-called grand coalition of Ms. Merkel’s conservatives and the Social Democrats — a combination that Ms. Merkel governed during her first term as chancellor, from 2005 to 2009.

Increasingly the talk has been about whether the country’s traditional conservative party would form an alliance with the more left-leaning and environmentalist Green party, which earned about 15 percent support in a survey released Tuesday by the polling group Insa.

Ms. Merkel’s conservatives earned 35 percent, placing them in the strongest position, but requiring they find a coalition partner, according to the poll published in the Bild newspaper.

For the first time in weeks, the poll showed the Free Democrats earning 5 percent support, enough to secure representation in Parliament, making them available to form a coalition.

Nevertheless, the chancellor is keeping her options open. In a playful dig at her coalition partner, Ms. Merkel drew laughs from the crowd by citing a recent satire as saying, “Perhaps God created the F.D.P. only to test us.”

Compared with all other possible constellations from Germany’s political scene, Ms. Merkel said nevertheless that the current government of conservatives and economic liberals had the most in common.

“We share common values and principles,” she said. “And these are the values and principles that we need to successfully overcome today’s challenges.”

Austrian Group Plans Suit Over Facebook Privacy Policies

BERLIN — An Austrian student group said Tuesday that it planned to challenge Facebook’s privacy policies in Irish court, alleging that the social networking giant had failed, despite repeated requests and formal complaints made by its members, to adapt to the restrictions of European data protection law.

The group, which calls itself Europe vs. Facebook, said it would begin collecting donations to challenge the policy in Ireland, where the company’s European business is incorporated. Max Schrems, an Austrian law student at the University of Vienna who organized the effort, said Facebook had no interest in adapting its service to meet stricter European privacy requirements.

“We have been pursing this for more than a year with Facebook, but the company has done only about 10 percent of what we had asked them to do,” said Mr. Schrems, 25. “Therefore, we are preparing to go to court.”

Facebook, in a statement, said its European privacy policy had been vetted and approved by Irish regulators and was in compliance with European law.

“The way Facebook Ireland handles personal data has been subject to thorough review by the Irish Data Protection Commissioner over the past year,” the company said. “Nonetheless, we have some vocal critics who will never be happy whatever we do and whatever the D.P.C. concludes.”

Mr. Schrems’s group, which he said was made up of about 10 students at the University of Vienna, filed 22 complaints in 2010 with the Office of the Data Protection Commissioner in Ireland, which regulates Facebook’s European business because it is incorporated there.

As a result of those complaints, the regulator conducted a public audit of Facebook’s privacy policies. In September it announced an agreement with the company that required, among other changes, that Facebook shorten the time it retained consumer data and refrain from building a photo archive on individuals without their prior consent.

But Mr. Schrems said in an interview that Facebook was still violating European law in many areas, including a requirement that Facebook provide users who request it with a full copy of all the data the company has collected on them. Mr. Schrems, a Facebook user since 2007, said he requested his own summary file from Facebook in 2010.

The company, whose global headquarters is in Menlo Park, California, responded by creating a self-service tool for users to extract the data, which Mr. Schrems said supplied him only with information going back to 2010. In addition, he alleged that Facebook’s privacy policy, which users are required to agree to before they can use the service, is too broad and violates European law.

“It is basically a collection of American legalese, which is intentionally vague and gives the company adequate leeway to do basically anything they want with your data,” Mr. Schrems said.

Thilo Weichert, the data protection supervisor for the German state of Schleswig-Holstein, which has also brought legal action against Facebook, said he supported the Austrian student group’s efforts.

“Facebook’s policy is much too vague and broad and does not conform with German or European law,” Mr. Weichert said in an interview. “We think that European privacy officials need to take common action on this.”

Mr. Weichert issued an administrative order in August 2011 that barred businesses in the state, which is located along Germany’s northern border with Denmark, from using Facebook’s social plug-ins like the Like button and Fan pages. The rationale for the order: Those applications collect information on users without their consent by inserting cookies, which track individual computers, through a user’s Web browser.

In November of last year, Mr. Weichert sued several local business organizations, including the state’s own Industrie- und Handelskammer, the equivalent of the local chamber of commerce, for creating their own fan pages on Facebook. The chamber and businesses that have not been identified have challenged that suit, which is pending in court in Kiel.

The privacy policies of Facebook, Google and some other U.S.-based Web companies have come under increasing criticism in Europe.

Sign Language Researchers Broaden Science Lexicon

Imagine trying to learn biology without ever using the word “organism.” Or studying to become a botanist when the only way of referring to photosynthesis is to spell the word out, letter by painstaking letter.

For deaf students, this game of scientific Password has long been the daily classroom and laboratory experience. Words like “organism” and “photosynthesis” — to say nothing of more obscure and harder-to-spell terms — have no single widely accepted equivalent in sign language. This means that deaf students and their teachers and interpreters must improvise, making it that much harder for the students to excel in science and pursue careers in it.

“Often times, it would involve a lot of finger-spelling and a lot of improvisation,” said Matthew Schwerin, a physicist with the Food and Drug Administration who is deaf, of his years in school. “For the majority of scientific terms,” Mr. Schwerin and his interpreter for the day would “try to find a correct sign for the term, and if nothing was pre-existing, we would come up with a sign that was agreeable with both parties.”

Now thanks to the Internet — particularly the boom in online video — resources for deaf students seeking science-related signs are easier to find and share. Crowdsourcing projects in both American Sign Language and British Sign Language are under way at several universities, enabling people who are deaf to coalesce around signs for commonly used terms.

This year, one of those resources, the Scottish Sensory Centre’s British Sign Language Glossary Project, added 116 new signs for physics and engineering terms, including signs for “light-year,”  (hold one hand up and spread the fingers downward for “light,” then bring both hands together in front of your chest and slowly move them apart for “year”), “mass” and “X-ray” (form an X with your index fingers, then, with the index finger on the right hand, point outward). 

The signs were developed by a team of researchers at the center, a division of the University of Edinburgh in Scotland that develops learning tools for students with visual and auditory impairments. The researchers spent more than a year soliciting ideas from deaf science workers, circulating lists of potential signs and ultimately gathering for “an intense weekend” of final voting, said Audrey Cameron, science adviser for the project. (Dr. Cameron is also deaf, and like all non-hearing people interviewed for this article, answered questions via e-mail.)

Whether the Scottish Sensory Centre’s signs will take hold among its audience remains to be seen. “Some will be adopted, and some will probably never be accepted,” Dr. Cameron said. “We’ll have to wait and see what happens.”

Ideally, the standardization of signs will make it easier for deaf students to keep pace with their hearing classmates during lectures. “I can only choose to look at one thing at a time,” said Mr. Schwerin of the F.D.A., recalling his science education, “and it often meant choosing between the interpreter, the blackboard/screen/material, or taking notes. It was like, pick one, and lose out on the others.”

The problem doesn’t end at graduation. In fact, it only intensifies as new discoveries add unfamiliar terms to the scientific lexicon. “I’ve had numerous meetings where I couldn’t participate properly because the interpreters were not able to understand the jargon and they did not know any scientific signs,” Dr. Cameron said.

One general complaint about efforts to standardize signs for technical terms is the idea that, much like spoken language, sign language should be allowed to develop organically rather than be dictated from above.

“Signs that are developed naturally — i.e., that are tested and refined in everyday conversation — are more likely to be accepted quickly by the community,” said Derek Braun, director of the molecular genetics laboratory at Gallaudet University in Washington, D.C., which he said was the first biological laboratory designed and administered by deaf scientists.

DealBook: UBS Described as Near Deal With U.S. and Britain on Rate Rigging

UBS, the Swiss banking giant, is close to reaching settlements with American and British authorities over the manipulation of interest rates, the latest case in a multiyear investigation that has rattled the financial industry and spurred a public outcry for broad reform.

UBS is expected to pay more than $450 million to settle claims that some employees reported false rates to increase the bank’s profit, according to officials briefed on the matter who spoke on the condition of anonymity because the talks were private.

If the bank agrees to the deals with various authorities, the collective penalties would yield the largest total fines to date related to the rate-rigging inquiry and would increase the likelihood that other financial institutions would face stiff penalties. Authorities dealt their first blow in the rate-rigging case in June when the British bank Barclays agreed to a $450 million settlement.

A spokeswoman for UBS declined to comment. The agencies leading the UBS investigation, the Commodity Futures Trading Commission, the Justice Department and Britain’s Financial Services Authority, also declined to comment.

The UBS case will provide a window into systemic problems in the rate-setting process, which affects how consumers and companies borrow money around the world. After reviewing thousands of internal bank e-mails and interviewing dozens of employees, the authorities have uncovered patterns of abuse at the major banks that help set benchmark interest rates.

Libor Explained

The sprawling investigation is focused on benchmarks like the London interbank offered rate, or Libor. The rate, a measure of how much banks charge each other for loans, is used to determine the costs of trillions of dollars of mortgages, credit card charges and student loans.

The authorities claim that UBS traders colluded with rival banks to influence rates in an effort to bolster their profits, according to officials briefed on the matter. Some traders at UBS were suspended this year over the matter.

Given the scope of the case, the UBS settlement is expected to heighten calls for a reform of the Libor system. Lawmakers are pushing to change the way banks report rates, providing more transparency to consumers, companies and investors that rely on the benchmark.

The reform movement gained momentum after global authorities secured the settlement with Barclays. Regulators had accused Barclays of reporting false rates, a scandal that prompted the resignation of the chief executive and other top officials at the bank.

Global authorities are now moving forward with civil and criminal cases, setting up the potential for major fines and regulatory sanctions. Some banks are in advanced settlement talks, including UBS and the Royal Bank of Scotland. The Royal Bank said it expected to disclose penalties before the firm’s next earnings release in February. Deutsche Bank said last month that it had set aside money to cover potential fines, although it was too early to predict the size.

American authorities are hoping to complete a deal with UBS by the middle of the month, according to officials briefed on the matter. The officials noted that the discussions could spill into next year. The talks could also break down, in which case the authorities would file a lawsuit against the bank.

It is unclear whether global authorities will act in tandem on the UBS case. The bank and the regulators would prefer to strike a deal together, but the agencies are proceeding at different speeds.

Investigators say the broader Libor case could go on for years.

Canadian, Swiss and Asian authorities as well as the Justice Department, the Commodity Futures Trading Commission and Britain’s Financial Services Authority are investigating the actions of more than a dozen banks. Along with UBS, the futures commission is focused on potential wrongdoing at two American banks, Citigroup and JPMorgan Chase, the officials said. HSBC is also under scrutiny.

In addition to the regulatory cases, the Justice Department has identified potential criminal wrongdoing by traders at Barclays and other banks. The banks also face private lawsuits from large investors like local governments, which claim to have suffered losses as a result of interest rate manipulation. The New York attorney general has subpoenaed 16 banks over their role in the scandal, an action that could foreshadow civil lawsuits. Analysts predict the financial industry could face penalties of up to $20 billion.

“The evidence that comes out of any future settlement is likely to be enormously helpful for our claims,” said David E. Kovel, a partner at the law firm Kirby McInerney who is representing clients in a potential class-action suit related to Libor.

For UBS, the Libor case comes at a difficult time.

It has faced a series of legal problems since the financial crisis. In 2009, the bank agreed to pay $780 million to settle accusations by American authorities that it helped wealthy clients avoid taxes.

In 2011, it announced a $2.3 billion loss prompted by a rogue trader, Kweku M. Adoboli, who received a seven-year jail sentence for fraud last month. The firm agreed to pay a $47.5 million penalty to the British authorities in connection with the trading loss.

In the Libor case, UBS has been eager to cooperate. It has already reached a conditional immunity deal with the antitrust arm of the Justice Department, which could protect the bank from criminal prosecution under certain conditions. It is also cooperating with Canadian antitrust authorities by handing over e-mails and other documents implicating other banks.

But it did acknowledge publicly that such deals would not shield the bank from potential penalties from other regulators. The Justice Department’s criminal unit, for instance, could still take action against the bank.

UBS disclosed last year that it was the subject of investigations related to Libor, saying it had received subpoenas from American and Japanese authorities. Swiss and British regulators have joined the UBS investigation, which involves a number of currencies in the Libor system.

The timing of the Libor cases against UBS depends in large part on cooperation among regulators.

The Financial Services Authority in Britain has worked closely with its American counterparts. In total, the British regulator has about 160 people working on its various cases against banks, which are at different stages of development.

As the top watchdog of London’s financial services industry, the British regulator has positioned itself as a conduit for document requests from international regulators regarding Libor, which is set daily by banks in London. The agency also organizes interviews for its American counterparts with London-based bankers involved in the inquiries, according to an official with direct knowledge of the matter.

British regulators had been ready to move against UBS a month after officials announced a settlement with Barclays, the person added. The settlement has been delayed, however, as global authorities have tried to pursue a joint agreement with the bank.

“We’ve been going at the pace of the slowest regulator,” the official said.

After Death of Sattar Beheshti, Iranian Blogger, Head of Tehran’s Cybercrimes Unit Is Fired

TEHRAN — Iranian’s national police chief fired the commander of Tehran’s cybercrimes police unit on Saturday for negligence in the death of a blogger in prison.

The dismissal of the commander, Gen. Saeed Shokrian, follows investigations by Parliament and Iran’s judiciary into the unexplained death of the blogger, Sattar Beheshti, 35, who died in early November just a few days after being arrested by the cybercrimes police unit, known here as FATA.

“Tehran’s FATA should be held responsible for the death of Sattar Beheshti,” said Iran’s national police chief, Ismael Ahmadi-Moqaddam, according to the Iranian Labor News Agency.

It is unclear whether General Shokrian will also face judicial charges over the blogger’s death.

The public nature of his dismissal suggests that he will bear most of the responsibility for the death. In similar cases in the past, officials have been punished, but it is rare for them to be named and publicly dismissed on the same day.

Mr. Beheshti’s Web site, My Life for My Iran, criticized Iran’s financial contributions to the Hezbollah movement in Lebanon. Mr. Beheshti posted pictures of Lebanese youths having parties alongside images of Iranians living in poverty.

The exact cause of Mr. Beheshti’s death remains murky. Mr. Ahmadi-Moqaddam said Tuesday that investigations had ruled out torture as a cause of death, saying it was possible that Mr. Beheshti, who in pictures looks big and strong, died of “psychological shock.”

Iranian activists and bloggers say Mr. Beheshti died of injuries following beatings. Iran’s judiciary spokesman, Gholam Hussein Mohseni-Ejei, recently admitted that Mr. Beheshti — while in prison — had lodged a written complaint against an interrogator, in which he accused the man of having beaten him during his detention in Tehran’s Evin prison.

“I, Sattar Beheshti, was arrested by FATA and beaten and tortured with multiple blows to my head and body,” read the document, published by the opposition Kalame Web site. He added, “If anything happens to me, the police are responsible.”

Mr. Ahmadi-Moqaddam said that Mr. Beheshti was given tranquilizers while in the prison’s clinic, but that when handed over to the cybercrimes unit its officers denied him the same tranquilizers. “This might be regarded as neglect,” he said. “However, there were no signs of beatings on his body.”

Official statements on the cause of death have been contradictory. An influential member of Parliament who earlier denied that Mr. Beheshti had been tortured in any way told the Tabnak Web site that the blogger had been beaten, but died of shock and fear.

“Definitely he was beaten inside the FATA detention center,” the lawmaker, Alaeddin Borujerdi, told the Web site, “but he didn’t die as a result of these beatings.” He also stressed that the cybercrimes unit must change the way it deals with prisoners.

Iranian activists who have been in contact with Mr. Beheshti’s family say his relatives were not allowed to see his body before a hurried funeral on Nov. 6 in his hometown, Robat Karim, 30 miles southwest of the capital, Tehran.

In Mr. Beheshti’s final post, on Oct. 29, a day before his arrest, he said he was being threatened by security officials. “They told me that if I didn’t close my big mouth my mother should prepare to wear black clothes,” for mourning.

The Iranian Parliament’s special investigator into the case, Mehdi Davatgari, said he welcomed the commander’s removal. “This move shows the civil rights of our citizens are our top priority,” he said.

Software Programs Help Doctors Diagnose, but Can’t Replace Them

SAN FRANCISCO — The man on stage had his audience of 600 mesmerized. Over the course of 45 minutes, the tension grew. Finally, the moment of truth arrived, and the room was silent with anticipation.

At last he spoke. “Lymphoma with secondary hemophagocytic syndrome,” he said. The crowd erupted in applause.

Professionals in every field revere their superstars, and in medicine the best diagnosticians are held in particularly high esteem. Dr. Gurpreet Dhaliwal, 39, a self-effacing associate professor clinical medicine at the University of California, San Francisco, is considered one of the most skillful clinical diagnosticians in practice.

The case Dr. Dhaliwal was presented, at a medical  conference last year, began with information that could have described hundreds of diseases: the patient had intermittent fevers, joint pain, and weight and appetite loss.

To observe him at work is like watching Steven Spielberg tackle a script or Rory McIlroy a golf course. He was given new information bit by bit — lab, imaging and biopsy results. Over the course of the session, he drew on an encyclopedic familiarity with thousands of syndromes. He deftly dismissed red herrings while picking up on clues that others might ignore, gradually homing in on the accurate diagnosis.

Just how special is Dr. Dhaliwal’s talent? More to the point, what can he do that a computer cannot? Will a computer ever successfully stand in for a skill that is based not simply on a vast fund of knowledge but also on more intangible factors like intuition?

The history of computer-assisted diagnostics is long and rich. In the 1970s, researchers at the University of Pittsburgh developed software to diagnose complex problems in general internal medicine; the project eventually resulted in a commercial program called Quick Medical Reference. Since the 1980s, Massachusetts General Hospital has been developing and refining DXplain, a program that provides a ranked list of clinical diagnoses from a set of symptoms and laboratory data.

And I.B.M., on the heels of its triumph last year with Watson, the Jeopardy-playing computer, is working on Watson for Healthcare.

In some ways, Dr. Dhaliwal’s diagnostic method is similar to that of another I.B.M. project: the Deep Blue chess program, which in 1996 trounced Garry Kasparov, the world’s best player at the time, to claim an unambiguous victory in the computer’s relentless march into the human domain.

Although lacking consciousness and a human’s intuition, Deep Blue had millions of moves memorized and could analyze as many each second. Dr. Dhaliwal does the diagnostic equivalent, though at human speed.

Since medical school, he has been an insatiable reader of case reports in medical journals, and case conferences from other hospitals. At work he occasionally uses a diagnostic checklist program called Isabel, just to make certain he hasn’t forgotten something. But the program has yet to offer a diagnosis that Dr. Dhaliwal missed.

Dr. Dhaliwal regularly receives cases from physicians who are stumped by a set of symptoms. At medical conferences, he is presented with one vexingly difficult case and is given 45 minutes to solve it. It is a medical high-wire act; doctors in the audience squirm as the set of facts gets more obscure and all the diagnoses they were considering are ruled out. After absorbing and processing scores of details, Dr. Dhaliwal must commit to a diagnosis. More often than not, he is right.

When working on a difficult case in front of an audience, Dr. Dhaliwal puts his entire thought process on display, with the goal of “elevating the stature of thinking,” he said. He believes this is becoming more important because physicians are being assessed on whether they gave the right medicine to a patient, or remembered to order a certain test.

Without such emphasis, physicians and training programs might forget the importance of having smart, thoughtful doctors. “Because in medicine,” Dr. Dhaliwal said, “thinking is our most important procedure.”

He added: “Getting better at diagnosis isn’t about figuring out if someone has one rare disease versus another. Getting better at diagnosis is as important to patient quality and safety as reducing medication errors, or eliminating wrong site surgery.”

Clinical Precision

Dr. Dhaliwal does half his clinical work on the wards of the San Francisco V. A. Medical Center, and the other half in its emergency department, where he often puzzles through multiple mysteries at a time.

One recent afternoon in the E.R., he was treating a 66-year-old man who was mentally unstable and uncooperative. He complained of hip pain, but routine lab work revealed that his kidneys weren’t working and his potassium was rising to a dangerous level, putting him in danger of an arrhythmia that could kill him — perhaps within hours. An ultrasound showed that his bladder was blocked.

There was work to be done: drain the bladder, correct the potassium level. It would have been easy to dismiss the hip pain as a distraction; it didn’t easily fit the picture. But Dr. Dhaliwal’s instinct is to hew to the ancient rule that physicians should try to come to a unifying diagnosis. In the end, everything — including the hip pain — was traced to metastatic prostate cancer.

“Things can shift very quickly in the emergency room,” Dr. Dhaliwal said. “One challenge of this, whether you use a computer or your brain, is deciding what’s signal and what’s noise.” Much of the time, it is his intuition that helps figure out which is which.

Software Programs Help Doctors Diagnose, but Can’t Replace Them

SAN FRANCISCO — The man on stage had his audience of 600 mesmerized. Over the course of 45 minutes, the tension grew. Finally, the moment of truth arrived, and the room was silent with anticipation.

At last he spoke. “Lymphoma with secondary hemophagocytic syndrome,” he said. The crowd erupted in applause.

Professionals in every field revere their superstars, and in medicine the best diagnosticians are held in particularly high esteem. Dr. Gurpreet Dhaliwal, 39, a self-effacing associate professor clinical medicine at the University of California, San Francisco, is considered one of the most skillful clinical diagnosticians in practice.

The case Dr. Dhaliwal was presented, at a medical  conference last year, began with information that could have described hundreds of diseases: the patient had intermittent fevers, joint pain, and weight and appetite loss.

To observe him at work is like watching Steven Spielberg tackle a script or Rory McIlroy a golf course. He was given new information bit by bit — lab, imaging and biopsy results. Over the course of the session, he drew on an encyclopedic familiarity with thousands of syndromes. He deftly dismissed red herrings while picking up on clues that others might ignore, gradually homing in on the accurate diagnosis.

Just how special is Dr. Dhaliwal’s talent? More to the point, what can he do that a computer cannot? Will a computer ever successfully stand in for a skill that is based not simply on a vast fund of knowledge but also on more intangible factors like intuition?

The history of computer-assisted diagnostics is long and rich. In the 1970s, researchers at the University of Pittsburgh developed software to diagnose complex problems in general internal medicine; the project eventually resulted in a commercial program called Quick Medical Reference. Since the 1980s, Massachusetts General Hospital has been developing and refining DXplain, a program that provides a ranked list of clinical diagnoses from a set of symptoms and laboratory data.

And I.B.M., on the heels of its triumph last year with Watson, the Jeopardy-playing computer, is working on Watson for Healthcare.

In some ways, Dr. Dhaliwal’s diagnostic method is similar to that of another I.B.M. project: the Deep Blue chess program, which in 1996 trounced Garry Kasparov, the world’s best player at the time, to claim an unambiguous victory in the computer’s relentless march into the human domain.

Although lacking consciousness and a human’s intuition, Deep Blue had millions of moves memorized and could analyze as many each second. Dr. Dhaliwal does the diagnostic equivalent, though at human speed.

Since medical school, he has been an insatiable reader of case reports in medical journals, and case conferences from other hospitals. At work he occasionally uses a diagnostic checklist program called Isabel, just to make certain he hasn’t forgotten something. But the program has yet to offer a diagnosis that Dr. Dhaliwal missed.

Dr. Dhaliwal regularly receives cases from physicians who are stumped by a set of symptoms. At medical conferences, he is presented with one vexingly difficult case and is given 45 minutes to solve it. It is a medical high-wire act; doctors in the audience squirm as the set of facts gets more obscure and all the diagnoses they were considering are ruled out. After absorbing and processing scores of details, Dr. Dhaliwal must commit to a diagnosis. More often than not, he is right.

DealBook: UBS Described as Near Deal With U.S. and Britain on Rate Rigging

UBS, the Swiss banking giant, is close to reaching settlements with American and British authorities over the manipulation of interest rates, the latest case in a multiyear investigation that has rattled the financial industry and spurred a public outcry for broad reform.

UBS is expected to pay more than $450 million to settle claims that some employees reported false rates to increase the bank’s profit, according to officials briefed on the matter who spoke on the condition of anonymity because the talks were private.

If the bank agrees to the deals with various authorities, the collective penalties would yield the largest total fines to date related to the rate-rigging inquiry and would increase the likelihood that other financial institutions would face stiff penalties. Authorities dealt their first blow in the rate-rigging case in June when the British bank Barclays agreed to a $450 million settlement.

A spokeswoman for UBS declined to comment. The agencies leading the UBS investigation, the Commodity Futures Trading Commission, the Justice Department and Britain’s Financial Services Authority, also declined to comment.

The UBS case will provide a window into systemic problems in the rate-setting process, which affects how consumers and companies borrow money around the world. After reviewing thousands of internal bank e-mails and interviewing dozens of employees, the authorities have uncovered patterns of abuse at the major banks that help set benchmark interest rates.

Libor Explained

The sprawling investigation is focused on benchmarks like the London interbank offered rate, or Libor. The rate, a measure of how much banks charge each other for loans, is used to determine the costs of trillions of dollars of mortgages, credit card charges and student loans.

The authorities claim that UBS traders colluded with rival banks to influence rates in an effort to bolster their profits, according to officials briefed on the matter. Some traders at UBS were suspended this year over the matter.

Given the scope of the case, the UBS settlement is expected to heighten calls for a reform of the Libor system. Lawmakers are pushing to change the way banks report rates, providing more transparency to consumers, companies and investors that rely on the benchmark.

The reform movement gained momentum after global authorities secured the settlement with Barclays. Regulators had accused Barclays of reporting false rates, a scandal that prompted the resignation of the chief executive and other top officials at the bank.

Global authorities are now moving forward with civil and criminal cases, setting up the potential for major fines and regulatory sanctions. Some banks are in advanced settlement talks, including UBS and the Royal Bank of Scotland. The Royal Bank said it expected to disclose penalties before the firm’s next earnings release in February. Deutsche Bank said last month that it had set aside money to cover potential fines, although it was too early to predict the size.

American authorities are hoping to complete a deal with UBS by the middle of the month, according to officials briefed on the matter. The officials noted that the discussions could spill into next year. The talks could also break down, in which case the authorities would file a lawsuit against the bank.

It is unclear whether global authorities will act in tandem on the UBS case. The bank and the regulators would prefer to strike a deal together, but the agencies are proceeding at different speeds.

Investigators say the broader Libor case could go on for years.

Canadian, Swiss and Asian authorities as well as the Justice Department, the Commodity Futures Trading Commission and Britain’s Financial Services Authority are investigating the actions of more than a dozen banks. Along with UBS, the futures commission is focused on potential wrongdoing at two American banks, Citigroup and JPMorgan Chase, the officials said. HSBC is also under scrutiny.

In addition to the regulatory cases, the Justice Department has identified potential criminal wrongdoing by traders at Barclays and other banks. The banks also face private lawsuits from large investors like local governments, which claim to have suffered losses as a result of interest rate manipulation. The New York attorney general has subpoenaed 16 banks over their role in the scandal, an action that could foreshadow civil lawsuits. Analysts predict the financial industry could face penalties of up to $20 billion.

“The evidence that comes out of any future settlement is likely to be enormously helpful for our claims,” said David E. Kovel, a partner at the law firm Kirby McInerney who is representing clients in a potential class-action suit related to Libor.

For UBS, the Libor case comes at a difficult time.

It has faced a series of legal problems since the financial crisis. In 2009, the bank agreed to pay $780 million to settle accusations by American authorities that it helped wealthy clients avoid taxes.

In 2011, it announced a $2.3 billion loss prompted by a rogue trader, Kweku M. Adoboli, who received a seven-year jail sentence for fraud last month. The firm agreed to pay a $47.5 million penalty to the British authorities in connection with the trading loss.

In the Libor case, UBS has been eager to cooperate. It has already reached a conditional immunity deal with the antitrust arm of the Justice Department, which could protect the bank from criminal prosecution under certain conditions. It is also cooperating with Canadian antitrust authorities by handing over e-mails and other documents implicating other banks.

But it did acknowledge publicly that such deals would not shield the bank from potential penalties from other regulators. The Justice Department’s criminal unit, for instance, could still take action against the bank.

UBS disclosed last year that it was the subject of investigations related to Libor, saying it had received subpoenas from American and Japanese authorities. Swiss and British regulators have joined the UBS investigation, which involves a number of currencies in the Libor system.

The timing of the Libor cases against UBS depends in large part on cooperation among regulators.

The Financial Services Authority in Britain has worked closely with its American counterparts. In total, the British regulator has about 160 people working on its various cases against banks, which are at different stages of development.

As the top watchdog of London’s financial services industry, the British regulator has positioned itself as a conduit for document requests from international regulators regarding Libor, which is set daily by banks in London. The agency also organizes interviews for its American counterparts with London-based bankers involved in the inquiries, according to an official with direct knowledge of the matter.

British regulators had been ready to move against UBS a month after officials announced a settlement with Barclays, the person added. The settlement has been delayed, however, as global authorities have tried to pursue a joint agreement with the bank.

“We’ve been going at the pace of the slowest regulator,” the official said.
