Burnt circuit boards snag Japan's 787 probe

A device seen as key to explaining why a Boeing Co. 787 Dreamliner jet made an emergency landing in Japan last week is burnt and unlikely to provide safety inspectors with data they need, said a person with knowledge of the ongoing investigation.

Circuit boards that control and monitor the performance of the plane's lithium-ion battery unit were charred and may be of little use to the teams investigating why the battery effectively melted, forcing safety investigators to scramble for possible clues from other components in the plane's electronics, said the person, who didn't want to be named as the probe is ongoing.

Aviation authorities in Japan face a painstaking reconstruction that may take months before they can unravel what caused one of the batteries to overheat, triggering warnings in the plane's cockpit.

That relatively inexpensive circuit boards may be keeping $10 billion worth of futuristic aircraft idle underscores how dependent the Boeing jet is on advanced electronics rather than more traditional, but less fuel-efficient, parts, experts said.

"The circuit board (system) is badly damaged. We'll see how much we can learn from examining it, but we'll also have to look at other recording devices on the aircraft to try and find out what happened," the person with direct knowledge of the investigation told Reuters.

BATTERY "BRAIN"

The circuit boards, known as the battery monitoring unit, are the "brains" of the battery, experts said. About the size of a laptop computer, the boards monitor functions of the lithium-ion battery's eight cells and feed this information to the charger. That effectively makes the boards responsible for preventing a battery from overcharging.

One key question for safety investigators is how the battery's eight individual cells became volatile even though the overall voltage to the battery was steady and didn't exceed the 32-volt capacity, officials have said. That data is not recorded in the Dreamliner's "black box" flight-data recorder.

U.S, Japanese and Boeing representatives have this week been at the Kyoto headquarters of GS Yuasa Corp, which makes batteries for the 787, looking at everything from manufacturing quality to technical standards.

The main battery from the All Nippon Airways flight is still at the GS Yuasa plant, where it is being cleaned and disassembled for further checks. Once they are done, Japanese safety officials plan to take the damaged circuit boards to the manufacturer, Fujisawa-based Kanto Aircraft Instrument, for a detailed inspection.

All 50 of Boeing's Dreamliners in service were grounded last week after the ANA-operated flight's emergency landing on a domestic flight. That followed an auxiliary battery fire in a Japan Airlines Co. Ltd 787 parked at Boston Airport.

"There is a possibility that a fire destroyed the elements that caused the problem and if so, it will become difficult to investigate the cause," said Hideaki Horie, project professor at the Institute of Industrial Science at Tokyo University.

Horie said Boeing should re-think the design of the battery safety and data recovery system even while it investigates what caused the recent Dreamliner incidents.

The 787 uses two lithium-ion batteries, which are about twice as large as a car battery. The batteries weigh less than a conventional battery and provide more power. They are Boeing's first step toward hybrid power systems like those used by automakers General Motors Co. and Toyota Motor Corp .

Girl: 'My sister's on fire'

By Carlos Sadovi




Tribune reporter

7:42 a.m. CST, January 24, 2013

A young girl was in critical condition this morning after she was pulled from a burning bed in her South Side home by neighbors who heard the desperate screams of her older sister.

"She came downstairs and was knocking on everyone's door," said Sandra Gray. "She was screaming, 'My sister's on fire.' "

Gray said she and her husband and a neighbor ran up the stairs of the four-flat and saw the bottom of a bunk bed on fire. "All I saw was that the bed was on fire and the baby was burned," Gray said. "You could see the bed on fire."

She said the older sister, 16, tried to pull the girl, around 4, from the bed and burned her hands. Gray's husband and the neighbor finally put the fire out with water as firefighters and paramedics arrived, she said.

Gray said the girl was conscious but badly burned.

Clyde Harden, who rushed up with Gray, said he grabbed hold of the little girl and helped put out the fire. “I believe that she was sheltered by God already,” he told reporters on the scene. “Somebody was there for her.”

The girls, along with a 10-year-old brother, were taken to Comer Children's Hospital. The young girl was listed in critical condition and the other two were in good condition, according to fire officials.

Gray said the teenager told her the children were alone in their apartment in the 1000 block of West 76th Street Wednesday evening. The 16-year-old said she was in a back bedroom doing her homework when the boy ran to her room around 7:15 p.m.

"The 10-year-old ran back there to tell her [their sister] was on fire," Gray said.

She said the fire was contained to the bedroom shared by the younger children.

Go forth and Tweet! Pope sees web networks as “portals of truth”

VATICAN CITY (Reuters) – Pope Benedict urged Catholics on Thursday to use social networks like Twitter and Facebook to win converts, as he launched his own smartphone app streaming live footage of his speeches.

The websites – often associated with endless postings of idle gossip and baby photos – could be used as “portals of truth and faith” in an increasingly secular age, the pontiff said in his 2013 World Communications Day message.

“Unless the Good News is made known also in the digital world, it may be absent in the experience of many people,” the 85-year old Pope said in the a letter published on the Vatican‘s website.

The Holy See has become an increasingly prolific user of social media since it launched its ‘new evangelization’ of the developed world, where some congregations have fallen in the wake of growing secularization and damage to the Church’s reputation from a series of sex abuse scandals.

The Pope himself reaches around 2.5 million followers through eight Twitter accounts, including one in Latin.

Belying his traditionalist reputation, the Pope praised connections made online which he said could blossom into true friendships. Online life was not a purely virtual world but “increasingly becoming part of the very fabric of society,” he said.

Social networks were also a practical tool that Catholics could use to organize prayer events, the pope suggested. But he called for reasoned debate and respectful dialogue with those with different beliefs, and cautioned against a tendency towards “heated and divisive voices” and “sensationalism”.

The websites were creating a new “agora”, he added, referring to the gathering spaces that were the centers of public life in ancient Greek cities.

The speech coincided with the launch of ‘The Pope App’, a downloadable program that streams live footage of the pontiff’s speaking events and Vatican news onto smartphones.

Pope Benedict‘s embrace of new media responds to the Church’s concern that it is invisible on the internet.

The Vatican commissioned a study of internet use and religion prior to the pope’s Twitter debut, which found the majority of U.S. Catholics surveyed were unaware of any significant Church presence online.

The New Old Age Blog: Grief Over New Depression Diagnosis

When the American Psychiatric Association unveils a proposed new version of its Diagnostic and Statistical Manual of Mental Disorders, the bible of psychiatric diagnoses, it expects controversy. Illnesses get added or deleted, acquire new definitions or lists of symptoms. Everyone from advocacy groups to insurance companies to litigators — all have an interest in what’s defined as mental illness — pays close attention. Invariably, complaints ensue.

“We asked for commentary,” said David Kupfer, the University of Pittsburgh psychiatrist who has spent six years as chairman of the task force that is updating the handbook. He sounded unruffled. “We asked for it and we got it. This was not going to be done in a dark room somewhere.”

But the D.S.M. 5, to be published in May, has generated an unusual amount of heat. Two changes, in particular, could have considerable impact on older people and their families.

First, the new volume revises some of the criteria for major depressive disorder. The D.S.M. IV (among other changes, the new manual swaps Roman numerals for Arabic ones) set out a list of symptoms that over a two-week period would trigger a diagnosis of major depression: either feelings of sadness or emptiness, or a loss of interest or pleasure in most daily activities, plus sleep disturbances, weight loss, fatigue, distraction or other problems, to the extent that they impair someone’s functioning.

Traditionally, depression has been underdiagnosed in older adults. When people’s health suffers and they lose friends and loved ones, the sentiment went, why wouldn’t they be depressed? A few decades back, Dr. Kupfer said, “what was striking to me was the lack of anyone getting a depression diagnosis, because that was ‘normal aging.’” We don’t find depression in old age normal any longer.

But critics of the D.S.M. 5 now argue that depression may become overdiagnosed, because this version removes the so-called “bereavement exclusion.” That was a paragraph that cautioned against diagnosing depression in someone for at least two months after loss of a loved one, unless that patient had severe symptoms like suicidal thoughts.

Without that exception, you could be diagnosed with this disorder if you are feeling empty, listless or distracted, a month after your parent or spouse dies.

“D.S.M. 5 is medicalizing the expected and probably necessary process of mourning that people go through,” said Allen Francis, a professor emeritus at Duke who chaired the D.S.M. IV task force and has denounced several of the changes in the new edition. “Most people get better with time and natural healing and resilience.”

If they are diagnosed with major depression before that can happen, he fears, they will be given antidepressants they may not need. “It gives the drug companies the right to peddle pills for grief,” he said.

An advisory committee to the Association for Death Education and Counseling also argued that bereaved people “will receive antidepressant medication because it is cheaper and ‘easier’ to medicate than to be involved therapeutically,” and noted that antidepressants, like all medications, have side effects.

“I can’t help but see this as a broad overreach by the APA,” Eric Widera, a geriatrician at the University of California, San Francisco, wrote on the GeriPal blog. “Grief is not a disorder and should be considered normal even if it is accompanied by some of the same symptoms seen in depression.”

But Dr. Kupfer said the panel worried that with the exclusion, too many cases of depression could be overlooked and go untreated. “If these things go on and get worse over time and begin to impair someone’s day to day function, we don’t want to use the excuse, ‘It’s bereavement — they’ll get over it,’” he said.

The new entry for major depressive disorder will include a note — the wording isn’t final — pointing out that while grief may be “understandable or appropriate” after a loss, professionals should also consider the possibility of a major depressive episode. Making that distinction, Dr. Kupfer said, will require “good solid clinical judgment.”

Initial field trials testing the reliability of D.S.M. 5 diagnoses, recently published in The American Journal of Psychiatry, don’t bolster confidence, however. An editorial remarked that “the end results are mixed, with both positive and disappointing findings.” Major depressive disorder, for instance, showed “questionable reliability.”

In an upcoming post, I’ll talk more about how patients might respond to the D.S.M. 5, and to a new diagnosis that might also affect a lot of older people — mild neurocognitive disorder.

U. of I. to launch tech research center in Chicago

Plans to launch a University of Illinois-affiliated technology research center in Chicago will be unveiled Thursday — the latest regional effort to stem an exodus of high-tech brainpower and entrepreneurship to the coasts.

A private, not-for-profit company, to be called UI Labs, is expected to open offices in or near the Loop to foster collaboration between the region's scientists and engineers from academia, industry and government.

The project, expected to be financed by private donations, corporate partnerships and federal grants, will be outlined for U. of I. trustees Thursday. The goal is to raise $20 million for first-year operations.

The aim is build a research and engineering powerhouse that will attract a range of industries to Chicago, along the lines of what the former Bell Labs did for the East Coast. The University of Illinois at Urbana-Champaign will offer up its vast tech resources, including the National Center for Supercomputing Applications and its Blue Waters supercomputer. It is anticipated other local universities and national research centers will participate.

"I was in India last week, talking with firms that were thinking of coming to Illinois to engage with university scientists," said U. of I. President Robert Easter. "And they say, 'We have a presence in Chicago or we're thinking of having a presence in Chicago, and it would be much more convenient if we could work with you there.'"

Or as project adviser James Duderstadt, president emeritus of the University of Michigan, put it, the U. of I. is among the top five universities in the nation in such high-tech fields as computer science and engineering, "but it's down there in the cornfields."

"All the pieces are there, but some of the things Chicago is lacking are things Urbana-Champaign has," he said.

The idea is to marry the two, helping Chicago attain the sort of direct scientific underpinnings that long have fostered tech hotbeds in Boston and the San Francisco Bay Area.

"This is an opportunity to essentially build some of the glue and connective tissue … and that's needed to keep students from leaving and, frankly, to grow some companies in Chicago," said Lesa Mitchell, vice president of innovation and networks for the Kansas City, Mo.-based Kauffman Foundation, which focuses on entrepreneurship.

Chicago faces intense competition nationwide, as many cities aim for technological prowess and growth. The start of the year brought the launch of a Cornell NYC Tech campus, for instance, a graduate program in applied sciences that will turn out high-level scientists in New York City.

In Illinois, the challenge is retaining talent. One telling statistic: 32 percent of computer science graduates from the U. of I. in Urbana-Champaign get jobs in California, said Larry Schook, the university's vice president for research.

Among U. of I. grads who made their names out West are Marc Andreessen, co-founder of Netscape; software entrepreneur Thomas Siebel, a major U. of I. donor; and Ray Ozzie, who recently retired as chief software architect for Microsoft Inc.

The goal of this project, supported by Gov. Pat Quinn and Mayor Rahm Emanuel, is to retain the next generation of Illinois-trained innovators.

The University of Illinois will have an affiliation agreement with the lab that would outline the flow of personnel, resources and services between them. The goal is to attract 250 faculty fellows during the first three years. Additionally, more than 1,000 undergraduate and graduate students are expected to participate in UI Labs training and entrepreneurial programs during the first five years.

"Some students and researchers prefer the city to a smaller community … so this could increase the quality of the faculty," said Bruce Rauner, a prominent Chicago venture capitalist who has worked on the development of this plan. "This can drive better research."

The intent is to develop a "junior year abroad program" as well, with the aim of attracting top students from overseas.

The UI Labs project will start within the next month or so, Schook said, with the naming of board members and a director search.

"We'd love to have … the smartest tech students in the world come to participate and stay here to create companies," Schook said.

Rauner, who made his fortune as co-founder of private equity firm GTCR and heads venture firm R8 Capital Partners, said he intends to participate in fundraising and to donate millions personally. Ultimately, to bring the center to world-class status, it may be necessary to raise a $300 million endowment, he said.

The University of Illinois has programs aimed at linking businesses to applicable academic research, including the University of Illinois at Chicago's Innovation Center and research parks at Chicago and Urbana. While those attempt to match faculty research with companies that could use it, the UI Labs model would aim for even deeper collaborative brainstorming, Easter said.

"A company struggling with a problem related to its technology could come in and sit with faculty who do theoretical work to see if those principles could lead to a solution," he said. "Out of that will come innovation, and that will drive economic growth."

200 firefighters battle massive Bridgeport warehouse blaze

Firefighters were still on the scene of a smoldering warehouse in Bridgeport this morning, pouring water on hot spots after a 5-11 alarm fire raced through the five-story building as a third of the department's on-duty personnel fought it.

The blaze was spotted by a fire chief passing by the former Harris Marcus Group building at 3757 S. Ashland Ave. shortly after 9 p.m. Extra alarms were quickly called as the fire spread throughout the warehouse and the roof collapsed and the more than 200 firefighters contended with frozen hydrants and icy ladders. The fire was finally brought under control around 12:30 a.m.

Chicago Fire Cmsr. Jose Santiago said the fire was Chicago's largest in seven years. "This was a very large fire, unbelievable fire load, a lot of wood, timber, old stuff, varnish," Santiago said on the scene. "Once it caught, it caught and ran.

"Everything is wood inside these buildings, beautiful façades on the outside. They've been up for a long time. When they start burning like this, they start coming down," Santiago said.

The commissioner said the freezing cold made the firefighters' job tougher. "We run into a lot of problems, like the ice weight on the building and ladders," Santiago said. "We had the Water Department to come out and steam off our ladders."

Heat from the fire could be felt several blocks away as flames climbed into the sky and ash rained down on cars.

"You could see the embers from the highway," said Darcy Benedict, a 28-year-old UIC medical school student. "I could see blue flames rising up."

Benedict and her boyfriend saw the fire from Interstate 55, a mile away, and got off the highway to get a better look.

At least 40 people stood behind police tape, bundled up and taking videos with cellphones. Several wondered how firefighters would be able to contain the blaze.

The commander at the scene called for a 5-11 with two "special alarms" to bring in special equipment and more manpower as the massive five started spreading to other buildings.

“I’m looking at the south side of the main fire building and there’s a big portion of exterior wall and roof collapse,” Fire Department spokeswoman Meg Ahlheim said as firefighters made progress around 10:30 p.m.

Special alarms are rare. A 5-11 with two special alarms was called in 2006 when a fire gutted the historic Wirt Dexter Building in the South Loop. That fire broke out before 3 p.m. on a weekday, snarled downtown traffic and forced the CTA to stop service on Loop L tracks.

There was a 5-11 alarm fire in the Avondale neighborhood on the Northwest Side last year. That fire burned for hours and required about 200 firefighters, but no special alarms were called.

Alarms normally escalate one at a time beyond a normal fire response up to a fifth alarm, though the scene commander skipped a fourth alarm Tuesday night once the fire jumped to another building.

First “Firefox OS” Phones Previewed, to Launch in February

Mozilla, the non-profit organization behind the popular Firefox web browser, has been promoting its Firefox OS project (once known as “Boot to Gecko”) for some time now. A hardware partnership with Telefonica, the international telecom giant, had been announced, but no phones had yet been unveiled.

But in an announcement today on its blog, Mozilla announced the impending launch of its first “developer preview” phones, the Keon and the Peak. Made in partnership with Geeksphone, a Spanish smartphone producer which used to make Android phones, these devices are meant to help app developers preview their work on the small screen. But they may also serve as a sneak preview of Mozilla’s plan to enter the smartphone market.

Introducing Firefox OS

Designed as an alternative to Google’s Android for low-powered smartphones, Firefox OS’ claim to fame is that it’s “built entirely using open web standards,” or open-source code written in the programming languages which make up the web, like JavaScript. Likewise, Firefox OS apps are websites specially formatted to look and feel like apps, and to respond to touchscreen controls and access phone features like vibration and the GPS.

A selection of Firefox apps is already available in the Mozilla Marketplace, but developers will eventually be able to take the open-source code behind it and create their own app markets like it if they so choose. These apps also run on the preview “Aurora” version of Firefox for Android, which is available for download from Mozilla’s website.

“Say ‘hola’” to the Keon and Peak

The Keon is Mozilla’s entry-level developer smartphone, while the Peak has somewhat more modern hardware specs.

The Keon has a 1 GHz Snapdragon processor, 512 MB of RAM, a 3.5-inch touchscreen, and 4 GB of flash memory, plus a microSD card slot to expand storage space. Its built-in camera is a basic 3-megapixel shooter, and lacks an LED flash. It’s roughly comparable to 2010′s iPhone 4 in terms of raw hardware specs, although it probably won’t be able to play the same kinds of 3D games since they’ll be written as web applications.

The Peak has a dual-core 1.2 GHz processor, a 4.3-inch IPS display, and an 8-megapixel camera with a flash, plus a 2-megapixel front-facing camera. It has the same amount of RAM and flash storage as the Keon does, though.

Both the Keon and the Peak are unlocked GSM smartphones, which may mean they will work on AT&T and T-Mobile’s networks in the States.

Pricing and availability

According to Peters, the “First phones will be available in February.” Prices have yet to be announced.

Jared Spurbeck is an open-source software enthusiast, who uses an Android phone and an Ubuntu laptop PC. He has been writing about technology and electronics since 2008.

The New Old Age Blog: Study Links Cognitive Deficits, Hearing Loss

There’s another reason to be concerned about hearing loss — one of the most common health conditions in older adults and one of the most widely undertreated. A new study by researchers at Johns Hopkins Medicine suggests that elderly people with compromised hearing are at risk of developing cognitive deficits — problems with memory and thinking — sooner than those whose hearing is intact.

The study in JAMA Internal Medicine was led by Dr. Frank Lin, a hearing specialist and epidemiologist who over the past several years has documented the extent of hearing problems in older people and their association with falls and the onset of dementia.

The physician’s work is bringing fresh, and some would say much-needed, attention to the link between hearing difficulties and seniors’ health.

In his new report, Dr. Lin looked at 1,984 older adults who participated over many years in the Health ABC Study, a long-term study of older adults conducted in Pittsburgh and Memphis. Participants’ mean age was 77; none had evidence of cognitive impairment when the period covered by this research began. In 2001 and 2002, they received hearing tests and cognitive tests; cognitive tests alone were repeated three, five and six years later.

The tests included the Modified Mini-Mental State exam, which is administered through an interview and yields an overall picture of cognitive status, and the Digit Symbol Substitution Test, a paper-only exercise that asks people to match symbols and numbers, which can reveal deficits in someone’s working memory and executive functioning.

Dr. Lin found that annual rates of cognitive decline were 41 percent greater in older adults with hearing problems than in those without, based on results from the Modified Mini-Mental State Exam. A five-point decline on that test is considered a “clinically significant” indicator of a change in cognition.

Using this information, Dr. Lin found that elderly people with hearing problems experienced a five-point decline on the exam in 7.7 years, compared with 10.9 years for those with normal hearing.

Results from the Digit Symbol Substitution Test showed the same downward trend, though not quite as steep: older people with hearing loss recorded a yearly rate of cognitive decline 32 percent greater on it than those with intact hearing. In both cases, the results showed an association only, with no proof of causality.

Still, given the fact that nearly two-thirds of adults age 70 and older have hearing problems, it is an important finding.

For caregivers and older adults, the bottom line is “pay attention to hearing loss,” said Kathleen Pichora-Fuller, a professor of psychology at the University of Toronto who was not involved in the study.

Most people seek medical attention for hearing difficulties 10 to 20 years after they first notice a problem, she said, because “there’s a stigma about hearing loss and people really don’t want to wear a hearing aid.” That means years of struggling with the consequences of impairment, without interventions that can make a difference.

One consequence that may help explain Dr. Lin’s findings is social isolation. When people have a hard time distinguishing what someone is saying to them, as is common in older age, they often stop accepting invitations to dinners or parties, attending concerts or classes, or going to family events. Over time, this social withdrawal can become a self-fulfilling prophecy, leading to the loss of meaningful relationships and activities that keep older people feeling engaged with others.

A substantial body of research by cognitive scientists has established that seniors’ cognitive health depends on exercising both body and brain and remaining socially engaged, and “now we have this intersection of hearing research and cognitive research lining up and showing us that hearing health is part of cognitive health,” said Dr. Pichora-Fuller, who originally trained as an audiologist.

Family physicians and internists, too, often dismiss older patients’ complaints about hearing, and should pay close attention to Dr. Lin’s research, she said.

“I hope this study will be a wake-up call to clinicians that auditory tests need to be part of the battery of tests they employ to look at an older person’s health,” agreed Patricia Tun, an adjunct associate professor of psychology at Brandeis University.

Although the tests are effective and cause no known harm, a panel of experts recently failed to recommend them for older adults because of a lack of supporting evidence, as I wrote last August.

Another potential explanation for Dr. Lin’s new finding lies in a concept known as “cognitive load” that Dr. Tun has explored through her research. Basically, this assumes that “we only have a certain amount of cognitive resources, and if we spend a lot of those resources of processing sensory input coming in — in this case, sound — it’s going to be processed more slowly and understand and remembered less well,” she explained.

In other words, when your brain has to work hard to hear and identify meaningful speech from a jumble of sounds, “you’ll have less mental energy for higher cognitive processing,” Dr. Tun said.

Even seniors who hear sounds relatively well often report that words sound garbled or mumbled, she noted, indicating a deterioration in hearing mechanisms that process complex speech.

Also, as yet unidentified biological or neurological pathways may affect both speech and cognition. Or hearing loss may exacerbate frailty and other medical conditions that older people oftentimes have in ways that are as yet poorly understood, Dr. Lin’s paper notes.

A limitation to his study is its reliance, in part, on the Modified Mini-Mental State exam, which asks older adults to respond to questions posed by an interviewer, according to Barbara Weinstein, a professor and head of the audiology program at CUNY’s Graduate Center.

Her research has shown that hearing-compromised seniors may not understand questions and answer incorrectly, confounding results. Another limitation arises from the failure to test participants’ hearing over time, as happened with cognitive tests, making associations more difficult to tease out.

Dr. Lin hopes to address this through another research project that would follow older adults over time and test whether interventions such as hearing aides help prevent the onset or slow the progression of cognitive decline. In the meantime, older people and caregivers should arrange for hearing tests if they have concerns, and consider getting a hearing aid if problems are confirmed.

Getting sound to the brain is the “first and most important step” in preventing sensory deprivation that can contribute to cognitive dysfunction, said Kelly Tremblay, a professor of speech and hearing science at the University of Washington.

Prosecutors: Peregrine Financial fraud loss exceeds $215M

Peregrine Financial Group's former chief executive stole more than $215 million from customers of his now-defunct futures brokerage and should be sentenced to the maximum 50 years in jail, U.S. prosecutors said Tuesday.

Russell Wasendorf Sr., 64, who founded the firm, has pleaded guilty to embezzlement but wants a lighter sentence, saying that the loss was less than $200 million and that he used "very basic, simple means" to carry out his fraud, according to documents filed by U.S. prosecutors.

Wasendorf, whose attempted suicide sent his firm into bankruptcy last July, is in jail in Iowa and will be sentenced Jan. 31.

U.S. prosecutors say the large loss, the sophisticated nature of the crime and the sheer number of victims -- more than 10,000 -- justify his spending the rest of his life behind bars.

"While some of defendant's individual acts might be characterized as simple in isolation, they were part of an exceedingly complex scheme whereby defendant's entire business was used as a mechanism to gather and purloin investor funds," prosecutors said in their sentencing memorandum, promising to fight any attempt by Wasendorf to receive a sentence of less than 50 years.

Prosecutors put the exact loss at $215,530,547, based on Peregrine's bank records, and will call Brenda Cuypers, the firm's chief financial officer, as a witness at the sentencing hearing next week.

They had previously pegged the embezzlement only at "more than $100 million," to which Wasendorf pleaded guilty.

Wasendorf's public defender has a policy of declining to comment on cases, and did not reply to an email from Reuters seeking comment.

The collapse last July of Peregrine Financial, known as PFGBest, dealt a blow to confidence in the U.S futures industry, already reeling from $1.6 billion hole in customer pockets left when giant brokerage MF Global failed nine months earlier.

Futures traders had never before suffered such large losses as a result of a brokerage failure.

"To see (Wasendorf) go to jail could give some people some hope," said James Koutoulas, co-head of the Commodity Customer Coalition, which fought to get customer money back in both bankruptcies. "In MF Global, justice hasn't been done."

No one has been charged with wrongdoing in MF Global's collapse.

Regulators have scrambled to patch perceived gaps in customer protections at brokerages and exchanges that handle contracts valued at some $2.5 trillion a day.

That figure is set to rise as new rules push over-the-counter swaps onto regulated trading venues.

The sentencing memorandum offers new details in the government's account of the fraud, which Wasendorf said in a July statement began in the early 1990s after he was hounded by an overzealous regulator.

The fraud began even earlier, prosecutors said in Tuesday's filing, when he stole at least $250,000 from customers' accounts to pay back the original financier of his brokerage, a person referred to in the document only by the initials "J.C."

"Using a copy machine, defendant fabricated a bank statement to conceal the theft of funds," the document said. For the next nearly 20 years, prosecutors said, he faked bank balances, fabricated deposits, and used a rented post office box in Cedar Falls, Iowa, to intercept letters from his auditors meant to check up on his balances at U.S. Bank.

He even went so far as to fly from Chicago, where his firm did most of its business, to Iowa to prevent the near-discovery of his fraud, ultimately convincing Peregrine and U.S. Bank employees that nothing was wrong, the document said.

All the while he worked to make Peregrine Financial seem much bigger and more successful than it was, they said.

Wasendorf believed that "if he could make himself appear rich, the auditors and regulators wouldn't be concerned with the state of his personal finances and not discover it was all a fraud," prosecutors quoted Wasendorf as saying in a sealed presentencing report.

But Peregrine was never actually profitable, even though by its demise investors had entrusted more than $376 million to him and his firm, they said.
