I guess I don't get it. If your doc is looking at radiologic images on his I-mac screen, run and run fast - this person should have no part in your health care if enjoy life at all. It sounds though that they're just using it as a portable HD, but any station capable of displaying these images at sufficient resolution should be on a network and able to access the Dot Mac database (which is a pretty sketchy way to store and transmit patient data - "software has a function that enables the physician to strip the image of any personal data that identifies the person, like their name, their date of birth etc. As long as that is done then it is a secure, anonymous system." Now that is also pretty frightening - it's just another place for mistakes to be made during coding and interpretation.
this article might as well of said that chewbaca is a wookie on endor.
Well, I wonder why they only went 10days with their experiment. your typical incandescent gives 1000 hours and a halogen gives even more. Maybe they were just in a hurry to get it published. I have definitely seen quantum dots bleach - not sure if the effect is thermal or if the fluorescence process is itself degrative. All the hype says they are unbleachable, they are certainly more robust than conventional fluors, but they do bleach and even blink. Afraid I could not find the mechanism, but here is documentation of someone else observing this: Journal of Microscopy Volume 202 Issue 1 Page 2 - April 2001 doi:10.1046/j.1365-2818.2001.00829.x
perhaps stablizing them in something like polyurethane and maybe keeping them cool is enough protection to prevent this from being a significant problem - but I'd like to see that this new lightbulb could at least last as long as current incandescendts before I get swept away in the hype.
Yep, I was wrong. The full text peer reviewed article is availabe: J. Am. Chem. Soc., ASAP Article 10.1021/ja055470d S0002-7863(05)05470-3 Web Release Date: October 18, 2005
Basically though: Magic-sized nanocrystals are so small that the electron wave function has significant overlap with the selenium surface sites.17,18 Therefore, any hole trapped on the surface would likely encounter the electron before nonradiatively relaxing to the ground state.
Quantum yield is currently only at 2-3% - I'd be curious to know what the theortical max for the quantum yield would be assuming better manufacturing of the dots. Also, these things do not last forever - in the paper they take them out to ten days of excitation, but I imagine it might be quite a challenge to extend the life of these.
Quantum dots are fluorescent in a unique way - they have a very wide excitation range in the blue/UV and very specific emission wavelengths with huge stokes shifts that depend on the radius of the excited dot (it's a quantum cavitation effect that I'm not even going to try to go into here). As for getting white light - my best guess is that he actually prepared a very sloppy batch of dots and the white light comes from many different sized dots and thus many different wavelengths being emitted at once.
No. that would be infrared imaging. N-IR imaging is actually looking at absorbance of oxy vs. deoxy hemoglobin. Wavelength absorbance=color you are actually looking at how red the brain is.
what, you think that when your brain gets very active, it also gets very red? =)
Yes. Brain activity requires increased blood flow to support its metabolism. This actually does change the color of the brain (more red in fact) and allows near infrared imaging through the skull to actually detect this change in color which can be correlated with activity.
I have exciting news regarding the shoes you walk miles in. I have recently been told by the lovely princess of my country that your shoes are in the custody of a large bank in my home village. I am looking forward to fufilling your proposition by procurring these shoes and walking 1.609 km (1 American mile). In order for this important walking to occur the bank has informed me that you, the owner of these shoes will have to make a payment to them of $55,000 of your dollars. Please understand that this value is exceptionally high because the honorable princess does not recognize you as a citizen of my country and taxes and surcharges are thusly added. However, I am offering to proxy for you by having you send me the amount that a local citizen must pay for release of these shoes from the bank - $8,000. I know that I can trust you very much not to inform others of this information until after I have walked 1 american mile in your buddy shoes. I am also looking to find out your peaches ncream and will be able to provide more information on this matter after I have secured the initial payment from you.
please send this amount so that soon you, I, the shoes buddy, and the princess will enjoy a bountiful harvest.
well, I think that is an invalid blanket statement. Most PDA's I've used run pocket-tunes just fine and there is nothing awful about the interface or the music quality or the batterylife. However, I do agree that the ipod interface is much better and if I didn't need pda functionality I would go for the ipod due to its smaller size, better interface, and larger storage volume. But I believe the number one reason that people don't spend just a bit more to get a multi-functional pda is that it's additional unstandardized complexity and get ready for this one slashdot readers - pda's are actually really friggin' dorky.
I know some people that carry an ipod and a pda around with them - to me this is not worth the hassle - I'm rarely away from a hot-sync long enough that I would need to justify lugging more than the 4gb of mp3s that fit on my pda around with me.
The ipod interface is great but Ultimately I do believe that storage will be the bottom-line. A blue-tooth phone/pda with friendlier/more powerful music software pocket-tunes is okay, but something better is needed, with 50+gb storage will ultimately be the ipod killer. Massive integration is surely the natural progression of portable electronics - the technology is still just on the fringe of allowing us to do this is a slick way.
Melon-farmer was also used as a dub in a TV broadcast of one of the lethal weapon movies.
Offensiveness is indeed one of the cores in modern american comedy. Look at South park and Family guy, shows that thrive on sarcastically playing off stereotypes and chiseling away at PC America.
Simpson's without the offensiveness will not bode well for America's reputation in the middle east.
Are you kidding?? Desktop media players are so far behind! They have to catch up to network television! I want a media player with a constant scroll ticker, animated graphics that pop up and consume the lower left quadrant of the screen every minute or so, and a memory and processor heavy 3D rendering engine that runs all the time just in case when I'm watching the credits for a movie I want to tilt them into the screen at a 35degree angle and shrink them so that I have room to watch advertisements that stream into my media player and are saved to my HD while I was watching the movie. But they'll be totally kick-ass advertisements geared towards me because the media player will automatically send microsoft a list of all media titles on my computer so they can build a psychological profile. Oh, and it damn well better support animated skins so I can make it look like it's on fire. I hear they might even integrate clippy the paper clip in WMP-11!
For all of you that are still buying the mantra "don't be evil" this should finally change your mind. purchasing part of/merging with time warner aol is like trading souls with the anti-christ.
what about color matching? I can get a pic to look good on my monitor, and by now I can get a pretty decent replication of it on my printer, but how do those of you that send pics out for printing deal with the color matching issue?
this explains so much. I thought I had just downloaded a really crappy new HBO show of the bit torrent network, but now I realize that I must have gotten the "junk data."
This is just evolution of a strategy the WB has been using for years where they broadcast junk data to prevent people from videotaping their programming.
Aww c'mon! It's bad enought that my old planets mneumonic has become useless currency in the last few months, now they're making it impossible to come up with a new one.
yeah, but it doesn't track. one burst of amo, then it's all over. with a tracking one, you could set it to conserve ammo by firing every five minutes, it would annoy/scare the hell out people or pets.
I don't think there really is a debate at this point. I love mozilla, but it's obviously not the iron tank many of us thought it was. I think talk about ie vs. mozilla with security is more bickering at this point - both have tried, both have failed. But it really goes to show that it's not trivial to make a highly functional browser and to predict all of the possible exploits and insecurities. That's not to say that we should give up.
hah, I'm picturing a great holiday Inn Express commercial -- a raggady bum looking guy in a ditch with a dirty suit. Another homeless guy comes up to him and asks him if he lost it all in the market, the reply? "no, but I did stay at a holiday inn express last night" pan to some sketchy dude with a card reader sipping champagne in a bathrobe in a holiday inn suite.
In my experience many hotels don't ask for the cards back, but some definitely do, and while they won't hassle you if you say you lost them, it does make for an awkward check out. bottom line is this stuff should not be on your room card because the cards are so disposable. Many people don't worry at all about losing these cards because the room number is not on them, and they know the front desk will hook them up with a new one in 10 secs.
The company claims that any attempts to mute the device somehow or plug in headphones will not affect the audibility of this alarm.
this is much more impressive than the scanner feature. How is NEC able to defy the basic laws of acoustic physics by making something that has a non-variabile decible level regardless of what you do to the device?
-- btw, I'm not sure the copyright concerns are worth worrying about. I've seen devices cable of doing this sort of thing much faster in libraries for years! no one seems to have cracked down on them yet.

yeah, but then Heraldo Rivera would give away every military secret we've got and the name of every CIA agent out there.
hey, wow it is just like google except you have to pay a hell of a lot for it, oh and it fucking sucks.
and since your usage will be tracked through your account, you'll probably end up getting sued someday.
