diagnosis-Related Groups (DRG) a system of classification or grouping of patients according to medical diagnosis for purposes of paying hospitalization costs. In 1983, amendments to Social Security contained a prospective payment plan for most Medicare inpatient services in the United States. The payment plan was intended to control rising health care costs by paying a fixed amount per patient. The program of DRG reimbursement was based on the premise that similar medical diagnoses would generate similar costs for hospitalization. Therefore, all patients admitted for a surgical procedure such as hernia repair would be charged the same amount regardless of actual cost to the hospital. If a patient's hospital bill should total less than the amount paid by Medicare, the hospital is allowed to keep the difference. If, however, a patient's bill is more than that reimbursed by Medicare for a specific diagnosis, the hospital must absorb the difference in cost. See also appendix of Diagnosis-Related Groups.

Patient discussion about diagnosis
Q. How is the diagnosis of autism made? My friend has a child who is suspected to have autism. I wanted to find out more about making the diagnosis of autism.
A. Diagnosing autism is not an easy task, especially when there are several other conditions that might confuse the clinician with this disorder or spectrum of disorders. The child usually has several symptoms that suggest an autistic disorder, such as impaired social behavior. Several diagnostic instruments (tests) are available. Two are commonly used in autism research: the Autism Diagnostic Interview-Revised (ADI-R) is a semistructured parent interview, and the Autism Diagnostic Observation Schedule (ADOS) uses observation and interaction with the child. The Childhood Autism Rating Scale (CARS) is used widely in clinical environments to assess severity of autism based on observation of children.
A pediatrician commonly performs a preliminary investigation by taking developmental history and physically examining the child.. If warranted, diagnosis and evaluations are conducted with help from ASD specialists, observing and assessing cognitive, communication, family, and other factors

Q. Is the diagnosis correct? I have been diagnosed bipolar and was previously diagnosed with depression and ADHD how I know the diagnosis is correct this time?
A. a psychologist/psychiatrist should also have the possibility with a questionary to detect if you have bipolar disorder and/or adhd. i have both and live with it since i am a child. i had my first "out-of-control"-crisis with 29 years. in the meantime i am 46 (in two days) and i still live! i had also many times the wish to make suicide, but this is the worst solution. do you live alone? do you have a dog? do you have a job? what are your talents? what do you love to do in life? write it down and look what you could put on a focus. what are the things you do daily that allows you to stop thinking of all your trouble? write it down. to make a puzzle? play chess with your neighbor? to chat online? you only can collect what could help you in such cases to keep the bad thoughts you have away from yourself. there is always at least one good solution. i give you here some ideas. never give up! thank you
Q. Who was the first person to be diagnosed with ADHD? Here is a question which I find very difficult to get an answer. Who was the first person to be diagnosed with ADHD? Take it easy to answer me my new friend. Thanks in advance.More discussions about diagnosis

Global Warming
We rely on your support
Take action
What's at Stake
Global warming is already having significant and harmful effects on our communities, our health, and our climate. Sea level rise is accelerating. The number of large wildfires is growing. Dangerous heat waves are becoming more common. Extreme storm events are increasing in many areas. More severe droughts are occurring in others.
We must take immediate action to address global warming or these consequences will continue to intensify, grow ever more costly, and increasingly affect the entire planet—including you, your community, and your family.
The good news is that we have the practical solutions at hand to dramatically reduce our carbon emissions, slow the pace of global warming, and pass on a healthier, safer world to future generations.
With your help, we can accomplish it. Even in these difficult times for climate action, we can make a difference.
Together, we can tackle global warming.

Global warming is happening now. The planet's temperature is rising. The trend is clear and unmistakable.
Every one of the past 40 years has been warmer than the 20th century average. 2016 was the hottest year on record. The 12 warmest years on record have all occurred since 1998.
Globally, the average surface temperature has increased more than one degree Fahrenheit since the late 1800s. Most of that increase has occurred over just the past three decades.
We are the cause. We are overloading our atmosphere with carbon dioxide, which traps heat and steadily drives up the planet's temperature. Where does all this carbon come from? The fossil fuels we burn for energy—coal, natural gas, and oil—plus the loss of forests due to deforestation, especially in the tropics.
The scientific evidence is clear. Within the scientific community, there is no debate. An overwhelming majority of climate scientists agree that global warming is happening and that human activity is the primary cause.

Global warming is already having significant and costly effects – and these consequences will only intensify as the planet's temperature continues to rise.
Accelerating Sea Level Rise Global warming is accelerating the rate of sea level rise and dramatically increasing coastal flooding risks, especially on the U.S. East Coast and Gulf of Mexico.
Longer and More Damaging Wildfire Seasons Wildfires are increasing and wildfire season is getting longer in the Western U.S. as temperatures rise.
More Frequent and Intense Heat Waves Dangerously hot weather is already occurring more frequently than it did 60 years ago.
Costly and Growing Health Impacts Climate change has significant implications for our health, including increased air pollution and a longer and more intense allergy season.
Heavier Precipitation and Flooding As temperatures increase, more rain falls during the heaviest downpours, increasing the risk of flooding events.

Reduce emissions
We must significantly reduce the heat-trapping emissions we are putting into the atmosphere. As individuals, we can help by taking action to reduce our personal carbon emissions. But to fully address the threat of global warming, we must demand action from our elected leaders.

Stop deforestation
Tropical deforestation accounts for about 10 percent of the world's heat-trapping emissions. Reducing tropical deforestation can significantly lower global warming emissions and plays an integral role in a comprehensive long-term solution to global warming.

Fight misinformation
Why has it been so difficult to achieve meaningful solutions to global warming? Media pundits, partisan think tanks, and special interest groups raise doubts about the truth of global warming. This barrage of misinformation misleads and confuses the public — and makes it more difficult to implement effective solutions.

Cassell's Encyclopedia of Queer Myth, Symbol, and Spirit: Gay, Lesbian, Bisexual, and Transgender Lore
Cassell, 1997 - Social Science - 382 pages
Did you know that in medieval French folklore a person might change sex by passing under a rainbow? Or that same-sex unions have been celebrated by peoples of the ancient Mediterranean, Africa, China, and indigenous America? Or that Sappho, da Vinci, Emily Dickinson, Nijinsky, Benjamin Britten, Mishima, Adrienne Rich, Audre Lorde, Keith Haring, Boy George, and Derek Jarman number among those who have explored the spiritual dimension of gender and sexuality in their works? While the terms many of us employ today to identify ourselves - 'queer', 'lesbian', 'gay', 'bisexual', 'transgendered' - differ markedly from those of peoples of other times and places, we are nevertheless the bearers of a rich spiritual history that has been ignored or suppressed, a history encoded in sacred texts as well as in works of art, music, dance and other media. Drawing upon religion, mythology, folklore, anthropology, history and the arts, the Encyclopedia is a cornucopia of queer spirituality, containing over 1,500 alphabetically arranged entries from Aakulujjuusi to Zeus.

The Lopsided Universe
Here's a new paper of mine, with Adrienne Erickcek and Mark Kamionkowski:
A Hemispherical Power Asymmetry from Inflation
Abstract: Measurements of temperature fluctuations by the Wilkinson Microwave Anisotropy Probe (WMAP) indicate that the fluctuation amplitude in one half of the sky differs from the amplitude in the other half. We show that such an asymmetry cannot be generated during single-field slow-roll inflation without violating constraints to the homogeneity of the Universe. In contrast, a multi-field inflationary theory, the curvaton model, can produce this power asymmetry without violating the homogeneity constraint. The mechanism requires the introduction of a large-amplitude superhorizon perturbation to the curvaton field, possibly a pre-inflationary remnant or a superhorizon curvaton-web structure. The model makes several predictions, including non-Gaussianity and modifications to the inflationary consistency relation, that will be tested with forthcoming CMB experiments.
The goal here is to try to explain a curious feature in the cosmic microwave background that has been noted by Hans Kristian Eriksen and collaborators: it's lopsided. We all (all my friends, anyway) have seen the pretty pictures from the WMAP satellite, showing the 1-part-in-100,000 fluctuations in the temperature of the CMB from place to place in the sky. These fluctuations are understandably a focus of a great deal of contemporary cosmological research, as (1) they arise from density perturbations that grow under the influence of gravity into galaxies and large-scale structure in the universe today, and (2) they appear to be primordial, and may have arisen from a period of inflation in the very early universe. Remarkably, from just a tiny set of parameters we can explain just about everything we observe in the universe on large scales.
The lopsidedness I'm referring to is different from the so-called axis of evil. The latter (in a cosmological context) refers to an apparent alignment of the temperature fluctuations on very large scales, which purportedly pick out a preferred plane in the sky (suspiciously close to the plane of the ecliptic). The lopsidedness is a different effect, in which the overall amplitude of fluctuations is a bit different (just 10% or so) in one direction on the sky than in the other. (A "hemispherical power asymmetry," if you like.)
What we're talking about is illustrated in these two simulations kindly provided by Hans Kristian Eriksen.
I know, they look almost the same. But if you peer closely, you will see that the bottom one is the lopsided one — the overall contrast (representing temperature fluctuations) is a bit higher on the left than on the right, while in the untilted image at the top they are (statistically) equal. (The lower image exaggerates the claimed effect in the real universe by a factor of two, just to make it easier to see by eye.)
What could cause such a thing? Our idea was that there was a "supermode" — a fluctuation that varied uniformly across the observable universe, for example if we were sampling a tiny piece of a sinusoidal fluctuation with a wavelength many times the size of our current Hubble radius.
The blue circle is our observable universe, the green curve is the supermode, and the small red squiggles are the local fluctuations that have evolved under the influence of this mode. The point is that the universe is overall just a little bit more dense on one side than the other, so it evolves just slightly differently, and the resulting CMB looks lopsided.
Interestingly, it doesn't quite work; at least, not in a simple model of inflation driven by a single scalar field. In that case, you can get the power asymmetry, but there is also a substantial temperature anisotropy — the universe is hotter on one side than on the other. There are a few back-and-forth steps in the reasoning that I won't rehearse here, but at the end of the day you get too much power on very large scales. It's no fun being a theoretical cosmologist these days, all the data keeps ruling out your good ideas.
But we didn't give up! It turns out that you can make things work if you have two scalar fields — one that does the inflating, cleverly called the "inflaton," and the other which is responsible for the density perturbations, which should obviously be called the "perturbon" but for historical reasons is actually called the "curvaton." By decoupling the source of most of the density in the universe from the source of its perturbations, we have enough wiggle room to make a model that fits the data. But there's not that much wiggle room, to be honest; we have an allowed region in parameter space that is not too big. That's good news, as it brings the hope that we can make relatively precise predictions that could be tested by some means other than the CMB.
One interesting feature of this model is that the purported supermode must have originated before the period of inflation that gave rise to the smaller-scale perturbations that we see directly in the CMB. Either it came from earlier inflation, or something entirely pre-inflationary.
So, to make a bit of a segue here, this Wednesday I gave a plenary talk at the summer meeting of the American Astronomical Society in St. Louis. I most discussed the origin of the universe and the arrow of time — I wanted to impress upon people that the origin of the entropy gradient in our everyday environment could be traced back to the Big Bang, and that conventional ideas about inflation did not provide straightforward answers to the problem, and that the Big Bang may not have been the beginning of the universe. I was more interested in stressing that this was a problem we should all be thinking about than pushing any of my favorite answers, but I did mention my paper with Jennie Chen as an example of the kind of thing we should all be looking for.
To an audience of astronomers, talk of baby universes tends to make people nervous, so I wanted to emphasize that (1) it was all very speculative, and (2) even though we don't currently know how to connect ideas about the multiverse to observable phenomena, there's no reason to think that it's impossible in principle, and the whole enterprise really is respectable science. (If only they had all seen my bloggingheads dialogue with John Horgan, I wouldn't have had to bother.) So I mentioned two different ideas that are currently on the market for ways in which influences of a larger multiverse might show up within our own. One is the idea of colliding bubbles, pursued by Aguirre, Johnson, and Shomer and by Chang, Kleban, and Levi. And the other, of course, was the lopsided-universe idea, since our paper had just appeared the day before. Neither of these possibilities, I was careful to say, applies directly to the arrow-of-time scenario I had just discussed; the point was just that all of these ideas are quite young and ill-formed, and we will have to do quite a bit more work before we can say for sure whether the multiverse is of any help in explaining the arrow of time, and whether we live in the kind of multiverse that might leave observable signatures in our local region. That's research for you; we don't know the answers ahead of time.
One of the people in the audience was Chris Lintott, who wrote up a description for the BBC. Admittedly, this is difficult stuff to get all straight the very first time, but I think his article gives the impression that there is a much more direct connection between my arrow-of-time work and our recent paper on the lopsided universe. In particular, there is no necessary connection between the existence of a supermode and the idea that our universe "bubbled off" from a pre-existing spacetime. (There might be a connection, but it is not a necessary one.) If you look through the paper, there's nothing in there about entropy or the multiverse or any of that; we're really motivated by trying to explain an interesting feature of the CMB data. Nevertheless, our proposed solution does hint at things that happened before the period of inflation that set up the conditions within our observable patch. These two pieces of research are not of a piece, but they both play a part in a larger story — attempting to understand the low entropy of the early universe suggests the need for something that came before, and it's good to be reminded that we don't yet know whether stuff that came before might have left some observable imprint on what we see around us today. Larger stories are what we're all about.

I bought my K52N 2010 August. Since that i've tried Ubuntu 10.something, Slackware 13, 13.37, Linux Mint, Pear Linux, and maybe some others also.
With sleeping mode i had problems with all the Distros. And when i put it into sleep (under a linux), usualy it doesn't seems to be sleep, its like it would start the process, but somehow it didn't finished so the main light didn't pulse. And after this it dosn't wake up by any button, not even the powerbutton, so i have to shoutdown it by putting the powerbutton about 3sec. And then when i want it on again, it didn't starts, the BIOS is not loading. First i was really shocked, then i removed the powercord, and puted it back, and voala it works again!
I'm currious does this problem have a solution yet, or its a common problem on Linuxlaptops?
With the rest:
Under Mint, and Pear (whitch are same as Ubuntu -i guess) camera works fine, it finds everything, i had problems also with the videocard on Mint after installing the external driver for it, it changed some caracters into "|||" an list was no longer vertical but 45°, i can't really tell it looks strange.
Under Slackware the camera is horizontaly fliped, the rest is ok.

HOUSTON - One person was killed in a collision between an SUV and a motorcycle in west Houston, and investigators said slick roads played a role in the wreck.
The wreck happened Tuesday at 5:30 a.m. on the feeder road of the West Sam Houston Tollway at Boheme Drive.
Houston police said it was pitch black and the roads were very wet when the crash occurred.
"The posted speeds are there for good weather, good driving conditions," Lt. M.J. Parrie. "Especially if we haven't had bad weather, the oils on the road always tend to make the road conditions very slick."
Police said the motorcyclist and driver of a Chevrolet Suburban were both traveling southbound on the feeder road and were trying to turn left on Boheme. Investigators said the driver of the Suburban skidded straight and slid into the motorcyclist.
"Unfortunately, the motorcyclist was trapped underneath the vehicle," Parrie said.
The motorcyclist died at the scene. His name has not been released.
Investigators said they questioned the driver of the Suburban and gave him a field sobriety test, but they don't think alcohol played a role in the incident.
