(AP) — House GOP leaders Tuesday floated a plan to fellow Republicans to counter an emerging Senate deal to reopen the government and forestall an economy-rattling default on U.S. obligations. But the plan got mixed reviews from the rank and file and it was not clear whether it could pass the chamber.

The measure would suspend a new tax on medical devices for two years and take away the federal government's contributions to lawmakers' health care and top administration officials. It would also fund the government through Jan. 15 and give Treasury the ability to borrow normally through Feb. 7.

House Speaker John Boehner, R-Ohio, said he's "trying to find a path forward" but that "there have been no decisions about exactly what we will do." He told a news conference, "There are a lot of opinions about what direction to go."

Senate Majority Leader Harry Reid, D-Nev., involved in negotiations with Senate GOP Leader Mitch McConnell of Kentucky, blasted the House plan as a blatant attack on bipartisanship.

"It can't pass the Senate and it won't pass the Senate," Reid said.

The move came as a partial shutdown entered its third week and less than two days before the Treasury Department says it will be unable to borrow and will rely on a this cash cushion to pay the country's bills.

The House GOP plan wouldn't win nearly as many concessions from President Barack Obama as Republicans had sought but it would set up another battle with the White House early next year.

"The jury is still out," said Rep. Michael Burgess, R-Texas.

Rep. Walter Jones, R-N.C., said he was not sure he could vote for the plan because it did not address the debt. "I have to know a lot more than I know now," he said.

The House move comes after conservative lawmakers rebelled at the outlines of an emerging Senate plan by Reid and GOP leader McConnell. Those two hoped to seal an agreement on Tuesday, just two days before the Treasury Department says it will run out of borrowing capacity.

The White House and Democrats quickly came out against the Republican plan. Obama planned to meet with House Democratic leaders Tuesday afternoon as negotiations continue.

"The latest proposal from House Republicans does just that in a partisan attempt to appease a small group of tea party Republicans who forced the government shutdown in the first place," said White House spokeswoman Amy Brundage. "Democrats and Republicans in the Senate have been working in a bipartisan, good-faith effort .... With only a couple days remaining until the United States exhausts its borrowing authority, it's time for the House to do the same."

"GOP's latest plan is designed to torpedo the bipartisan Sen solution," tweeted Rep. Chris Van Hollen, D-Md. "Plan is not only reckless, it's tantamount to default."

Political pressure is building on Republicans to reopen the government and GOP leaders are clearly fearful of failing to act to avert a default on U.S. obligations.

Republicans are in a difficult spot, relinquishing many of their core demands as they take a beating in the polls. Rep. Steve Southerland, R-Fla., led GOP lawmakers in several verses of "Amazing Grace."

"We have to stick together now," said Rep. Pete Sessions, R-Texas.

Like the House GOP bill, the emerging Senate measure — though not finalized — would reopen the government through Jan. 15 and permit the Treasury to borrow normally until early to mid-February, easing dual crises that have sapped confidence in the economy and taken a sledgehammer to the GOP's poll numbers.

"There are productive negotiations going on with the Republican leader," Reid said as he opened the Senate Tuesday. "I'm confident we'll be able to reach a comprehensive agreement this week in time to avert a catastrophic default."

On Wall Street, stocks were mixed early Tuesday, with investors somewhat optimistic over a potential deal.

"We're willing to get the government open. We want to get the government open," Scalise said. "Hopefully they get something done that addresses the spending issue."

The competing House and Senate plans are a far cry from the assault on "Obamacare" that tea party Republicans originally demanded as a condition for a short-term funding bill to keep the government fully operational. It lacks the budget cuts demanded by Republicans in exchange for increasing the government's $16.7 trillion borrowing cap.

Nor do either the House or Senate frameworks contain any of a secondary set of House GOP demands, like a one-year delay in the health law's mandate that individuals buy insurance.

Another difference between the Democrats and Republicans involves a Democratic move to repeal a $63 fee that companies must pay for each person they cover under the big health care overhaul beginning in 2014. Unions oppose the fee and Senate Democrats are pressing to repeal it, but House Republicans are positioning to block them and Senate Republicans are adamantly opposed as well.

Democrats were standing against a GOP-backed proposal to suspend a medical device tax that was enacted as part of the health care law, but might not be able to win a floor vote since many Democrats oppose the tax too.

Democratic and Republican aides described the outlines of the potential agreement on condition of anonymity because the discussions were ongoing.

But with GOP poll numbers plummeting and the country growing weary of a shutdown entering its third week, Senate Republicans in particular were eager to end the shutdown — and avoid an even greater crisis if the government were to default later this month.

Any legislation backed by both Reid and McConnell can be expected to sail through the Senate, though any individual senators could delay it.

But it's another story in the House. Rep. Joe Barton, R-Texas, signaled that conservative members of the House were deeply skeptical. He said any bill had to have serious spending cuts for him to vote to raise the debt ceiling and said he thought Obama and Treasury Secretary Jack Lew had more flexibility than they had said publicly.

"No deal is better than a bad deal," Barton said.

In addition to approving legislation to fund the government until late this year and avert a possible debt crisis later this week or month, the potential pact would set up broader budget negotiations between the GOP-controlled House and Democratic-led Senate. One goal of those talks would be to ease automatic spending cuts that began in March and could deepen in January, when about $20 billion in further cuts are set to slam the Pentagon.

Democrats also were seeking to preserve the Treasury Department's ability to use extraordinary accounting measures to buy additional time after the government reaches any extended debt ceiling. Such measures have permitted Treasury to avert a default for almost five months since the government officially hit the debt limit in mid-May, but wouldn't buy anywhere near that kind of time next year, experts said.

The House GOP plan would repeal the extraordinary measures, which would make the Feb 7 date a hard deadline to revisit the fight.

(AP) — A central Florida man says allegations that his 14-year-old daughter bullied a 12-year-old girl who killed herself are not true.

Polk County Sheriff Grady Judd said Tuesday authorities arrested the 14-year-old girl after she admitted online over the weekend that she had harassed Rebecca Sedwick.

A man who answered the phone at the 14-year-old's Lakeland home identified himself as her father. He told The Associated Press that his daughter was "a good girl" and he was "100 percent sure that whatever they're saying about my daughter is not true."

A 12-year-old girl was also arrested in the case. A message left at her Lakeland home was not immediately returned.

Rebecca climbed at tower at an abandoned concrete plant Sept. 9 and hurled herself to her death.

AP generally doesn't identify juveniles charged with crimes.

THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP's earlier story is below.

Two girls were arrested in a Florida bullying case after one of them admitted online over the weekend that she harassed a 12-year-old girl killed herself last month, a sheriff said Tuesday.

Polk County Sheriff Grady Judd said they arrested a 14-year-old girl because they were worried she would continue cyberbullying other girls. The girl is accused of bullying 12-year-old Rebecca Sedwick, who climbed at tower at an abandoned concrete plant Sept. 9 and hurled herself to her death.

Judd said arrested the 14-year-old girl after she posted online Saturday that she bullied Rebecca and she didn't care.

"We decided that we can't leave her out there. Who else is she going to torment, who else is she going to harass?" Judd said.

Police also arrested a 12-year-old girl who is accused of bullying Rebecca. Both have been charged with felony aggravated stalking.

The sheriff's office identified the two girls, but The Associated Press generally does not name juveniles charged with crimes.

Judd said the bullying began after the 14-year-old girl started dating a boy that Rebecca had been seeing.

She "didn't like that and began to harass and ultimately torment Rebecca," Judd said.

The 12-year-old girl was Rebecca's former best friend, but Judd said the 14-year-old girl turned her against Rebecca. Other girls also stopped being friends with her in fear of being bullied, the sheriff said.

Authorities have said Rebecca was "terrorized" by as many as 15 girls who ganged up on her and picked on her for months through online message boards and texts.

Witnesses told investigators the 14-year-old girl told Rebecca "to drink bleach and die" and said she should kill herself.

Judd said neither girl's parents wanted to bring their daughters to the sheriff's office, so detectives went to their homes and arrested them.

Judd said the 14-year-old was "very cold, had no emotion at all upon her arrest."

Ordinary investors don't stand much chance of beating the market. It moves way too fast and efficiently. Or it behaves in ways that make no sense at all.

Three Americans won the Nobel prize in economics Monday for their sometimes-contradictory insights into the complexities of investing.

Eugene Fama and Lars Peter Hansen of the University of Chicago and Robert Shiller of Yale University were honored for shedding light on the forces that move stock, bond and home prices — findings that have transformed how people invest.

Fama's research revealed the efficiency of financial markets: They absorb information so fast that individual investors can't outperform the markets as a whole. His work helped popularize index funds, which reflect an entire market of assets, such as the Standard & Poor's 500 stock index.

"Fama's work was incredibly fundamental in the '60s and '70s," said David Warsh, who follows economists at his Economic Principals blog. "It led to enormous practical change in terms of people not buying particular stocks but buying index funds."

Shiller's research examined asset prices from a contrasting angle. He showed that in the long run, stock and bond markets can behave irrationally, reaching prices that are out of whack with economic fundamentals.

Shiller, 67, predicted the dot-com crash of the early 2000s and the implosion of home prices in 2007. He has also been a pioneer in the field of behavioral economics, or how human emotions, biases and preferences can collectively influence financial markets.

Using mathematical tools like the well-known Case-Shiller index of home prices, Shiller has expanded the available information on asset prices.

Meb Faber, chief investment officer at Cambria Investment Management, said his firm uses a model developed by Shiller to seek stock bargains around the world.

Hansen has focused on statistical models, creating ways to test competing theories of why asset prices move as they do.

Fama and Shiller "provide the ends of the spectrum" between those who believe financial markets are efficient and those who think them deeply flawed, with Hansen "in the middle doing the math," said Allen Sanderson, a University of Chicago lecturer in economics.

The three economists share the $1.2 million prize, the last of this year's Nobels to be announced.

"Their methods have shaped subsequent research in the field, and their findings have been highly influential both academically and practically," the Royal Swedish Academy of Sciences said in Stockholm.

Fama, 74, and Hansen, 60, became the 11th and 12th professors from the University of Chicago to win a Nobel in economics, the most for any university. Harvard is second, with six laureates.

Hansen said he received the phone call from Sweden while on his way to the gym Monday morning. He said he was "still working on taking a deep breath."

Fama was preparing to teach his first class as a Nobel laureate Monday. Asked whether his students would get a break, he said: "We'll see, but they're going to get an exam tomorrow, anyway. They paid their money; they're going to get the full pill."

The Nobel prizes in medicine, chemistry, physics, literature and peace were created by Swedish industrialist Alfred Nobel in 1895. Sweden's central bank added the economics prize in 1968 as a memorial to Nobel.

Americans have dominated the Nobel in economics in recent years. The last time there was no American among the winners was 1999.

Collectively, Fama, Shiller and Hansen didn't create a simple, unified theory of how financial markets work. Rather, they worked like "blind men feeling an elephant" — each finding a bit of the truth in a vast and complicated field, Sanderson said.

Fama's work drew criticism after the financial crisis of 2007-09 seemed to prove that financial markets were anything but efficient. Housing prices, after all, had scaled great heights and then crashed.

But David Backus, an economist at New York University, said "people completely misunderstand" what Fama was arguing.

"He said that information out there will be reflected in (asset) prices. That is completely different from saying financial markets work well," Backus said.

It was striking that Monday's prize went to both Fama and Shiller, who emphasizes not market efficiency but market failures and inefficiencies.

"The committee covered all the bases," George Mason University economist Tyler Cowen quipped on his blog, Marginal Revolution.

Still, the University of Chicago's Sanderson said Fama, with his belief that investors can't outsmart the market, and Shiller, with his study of financial excess, would probably offer similar investment advice.

"Both would probably say: 'Don't spend a whole lot of time listening to your stockbroker.'"

Anthony Hopkins Gushes Over 'Breaking Bad' Star Bryan Cranston in Fan Letter




Getty Images


Anthony Hopkins and Bryan Cranston



Count Anthony Hopkins among the legions of Breaking Bad fans who couldn’t get enough of the show.



Just over two weeks after the AMC drama aired its series finale, a letter surfaced that Hopkins wrote to star Bryan Cranston, in which he gushes over the actor's performance. Hopkins says he just finished watching a marathon of all five seasons of the show (he refers to a sixth season, but the fifth season was actually split into two).


PHOTOS: What's Next for 'Breaking Bad's' Stars


"A total of two weeks (addictive) viewing," he writes. "I have never watched anything like it. Brilliant! Your performance as Walter White was the best acting I have seen -- ever. I know there is so much smoke blowing and sickening bullshit in this business, and I’ve sort of lost belief in anything really. But this work of yours is spectacular -- absolutely stunning. What is extraordinary, is the sheer power of everyone in the entire production."


Hopkins also goes on to praise the rest of the cast as well, and asks Cranston to "pass on my admiration to everyone."


"Everyone gave master classes of performance," he writes.


He also praises the Vince Gilligan-created show's overall arc and storytelling.


"From what started as a black comedy, descended into a labyrinth of blood, destruction and hell," he writes. "It was like a great Jacobean, Shakespearian [sic] or Greek Tragedy."


The letter first surfaced over the weekend on Breaking Bad co-star Steven Michael Quezada's Facebook page, according to Gawker, but the post has since been deleted, as has a tweet he wrote about the letter. But The Hollywood Reporter has confirmed that Hopkins is indeed the author and that the letter is authentic.

The Breaking Bad series finale aired Sept. 29, drawing a record 10.3 million viewers.


While many in Hollywood tweeted their enthusiasm for the show and especially the series finale, Oliver Stone and Britney Spears recently expressed their displeasure with the events of the final episode.


Read Hopkins' full letter below.


Dear Mister Cranston.


I wanted to write you this email – so I am contacting you through Jeremy Barber – I take it we are both represented by UTA . Great agency.


I’ve just finished a marathon of watching “BREAKING BAD” – from episode one of the First Season – to the last eight episodes of the Sixth Season. (I downloaded the last season on AMAZON) A total of two weeks (addictive) viewing.


I have never watched anything like it. Brilliant!


Your performance as Walter White was the best acting I have seen – ever.


I know there is so much smoke blowing and sickening bullshit in this business, and I’ve sort of lost belief in anything really.


But this work of yours is spectacular – absolutely stunning. What is extraordinary, is the sheer power of everyone in the entire production. What was it? Five or six years in the making? How the producers (yourself being one of them), the writers, directors, cinematographers…. every department – casting etc. managed to keep the discipline and control from beginning to the end is (that over used word) awesome.


From what started as a black comedy, descended into a labyrinth of blood, destruction and hell. It was like a great Jacobean, Shakespearian or Greek Tragedy.


If you ever get a chance to – would you pass on my admiration to everyone – Anna Gunn, Dean Norris, Aaron Paul, Betsy Brandt, R.J. Mitte, Bob Odenkirk, Jonathan Banks, Steven Michael Quezada – everyone – everyone gave master classes of performance … The list is endless.


Thank you. That kind of work/artistry is rare, and when, once in a while, it occurs, as in this epic work, it restores confidence.


You and all the cast are the best actors I’ve ever seen.


That may sound like a good lung full of smoke blowing. But it is not. It’s almost midnight out here in Malibu, and I felt compelled to write this email.


Congratulations and my deepest respect. You are truly a great, great actor.


Best regards


Tony Hopkins.

Art Wars: 12 Stormtrooper Helmets Get Hilarious High-Art Makeovers

Art Wars: 12 Stormtrooper Helmets Get Hilarious High-Art Makeovers


In a film packed with great costume and set design (Leia's buns! The AT-ATs! Tauntaun guts!), the Stormtroopers' glistening white exoskeletons are among the most memorable details from Star Wars. Which is what makes Art Wars a lot of fun: As part of a show at London mega-gallery Saatchi, 19 artists were given a trooper helmet and told to go wild.

New technique enables accurate, hands-free measure of heart and respiration rates

New technique enables accurate, hands-free measure of heart and respiration rates

Augusta, Ga. - A simple video camera paired with complex algorithms appears to provide an accurate means to remotely monitor heart and respiration rates day or night, researchers report.


The inexpensive method for monitoring the vital signs without touching a patient could have major implications for telemedicine, including enabling rapid detection of a heart attack or stroke occurring at home and helping avoid sudden infant death syndrome, according to a study published in the journal PLOS ONE.


It also may enable untethered, more realistic monitoring of laboratory animals in scientific research as well as ecological research on wild or endangered animal populations.


"Heart and respiratory rates obviously tell us a lot about how an individual is doing," said Dr. Joe Tsien, neuroscientist at the Medical College of Georgia at Georgia Regents University. "Normally, caregivers have to put their hands on a patient to assess these rates. However our algorithms enable us to rapidly and accurately translate, for example, normally imperceptible movement of the skin in rhythm with our breathing into an accurate measure of respiration rate."


Scientists at MCG and China's BanNa Biomedical Research Institute already are working to see if the approach can also accurately measure blood pressure.


Tsien, who studies memory, said the algorithms were developed to decipher reams of information generated by his brain-decoding project, which is identifying brain activity patterns that occur, for example, when a mouse forms a memory. In that case, the formulas help him understand what the brain is saying; in this case, they help interpret how the body is doing.


To measure heart rate, this approach takes advantage of the fact that the blood vessels expand and contract with each heartbeat: more blood in the vessels means more camera light is absorbed rather than reflected. Breathing causes a slight body movement that produces varying lengths of reflected light off the moving surface. In fact, Tsien notes, the two rates are closely tied and respiration rate can also be calculated based on heart rate, using his algorithms as well as other methods.


Within a few seconds, the algorithms enable light reflections to be sorted by source so that ambient signals from, say, a fluorescent lamp, can be ignored and distinct numbers can be calculated for heart and respiration rates.


"It lets us pull out only the faint but relevant signal that may be buried under ambient distractions," Tsien said.


False-positive rates were less than 3 percent and false negatives under 1 percent, indicating the device would be reliable even in rapidly changing scenarios such as a heart attack or stroke.


Measurements were taken multiple times on 15 human subjects, including seven males, eight females and one infant, who were a mix of Caucasians, Asians and blacks. To assess accuracy, heart and respiratory rates were concurrently measured using standard approaches such as an electrocardiogram for the heart and airflow captured by a sensor under the nose while subjects were active and stationary. Similar studies were performed on mice, pigs and zebrafish.


To further assess accuracy, scientists also used the approach on still images such as photographs of humans, a Simpson cartoon character and the Mona Lisa painting. Their system correctly identified all as inanimate objects. They also applied the technique to television footage of celebrities such as Michael Phelps and President Bill Clinton, and were able to detect varying heart and respiration rates in calm, happy and stressful situations.


Although the researchers used a single-channel camera which produces images from a single light source their algorithm can work with any video camera as well as other sensors, such as radio frequency waves, Tsien said. However, the researchers note that a previous attempt by others using a multi-channel camera for remote monitoring did not accurately measure parameters at night and generated significantly more false positives.



Tsien is the Georgia Research Alliance Eminent Scholar in Cognitive and Systems Neurobiology. GRU Postdoctoral Fellow Fang Zhao is the study's first author. GRU has patented the monitoring technique.

Although the researchers used a single-channel camera which produces images from a single light source their algorithm can work with any video camera as well as other sensors, such as radio frequency waves, Tsien said. However, the researchers note that a previous attempt by others using a multi-channel camera for remote monitoring did not accurately measure parameters at night and generated significantly more false positives.



Tsien is the Georgia Research Alliance Eminent Scholar in Cognitive and Systems Neurobiology. GRU Postdoctoral Fellow Fang Zhao is the study's first author. GRU has patented the monitoring technique.
