phy electronics molecules

shared by pacome delva on 09 Nov 09 - Cached
  • European researchers have measured the electrical conductance between a single pair of precisely oriented C60 molecules.
  • For the ultimate in miniaturization, researchers want to learn all they can about using molecules in electronic circuits. They have measured currents between molecules but not with a precise understanding of the configuration and positions of the molecular electrons.

    Finally a massively multi-core general-purpose architecture.
  • Ma Ru on 03 Dec 09
     
    Well, nice, but I wonder how much cache per core will be available... With 48 cores a single memory bus becomes nothing more than one big (small? :) ) bottleneck.
  • Francesco Biscani on 03 Dec 09
     
    Apparently they have separated L2 cache per-tile (i.e., every two processors) and a high speed bus connecting the tiles. As usual, whether it will be fast enough will depend from the specific applications (which BTW is also true for other current multi-core architectures). The nice thing is of course that porting software to this architecture will be one order of magnitude less difficult than going to Tesla/Fermi/CELL architectures. Also, this architecture will also be suitable for other tasks than floating point computations (damn engineers polluting computer science :P) and it has the potential to be more future-proof than other solutions.

    still only a few percent of conversion efficiency but very promising since working at reasonably focussing and unpolarised light; they announce the publication of a first design of such a system .... to be followed!! Duncan: you wanna have a closer look at it?
  • Luzi Bergamin on 18 Apr 11
     
    99% house advertising, 1% scientific results. I think this is still a conservative guess... And I'm sure this "completely new" effect that you don't see when "staring at the equations of motion" (doggone, how I love this USish "I-am-better-than-the-rest-of-the-world" jargon) certainly has been predicted at least 50 years ago by some smart USSR researcher!!

    Yeah that's interesting stuff... We have one prof in the lab who used to do some research related exactly to this (http://www.tech.plym.ac.uk/socce/staff/tonybelpaeme/research.html). Similar question (i.e. if/how language is involved in the formation of a concept) is also valid for numbers, see for instance this recent story: http://www.newscientist.com/article/dn20095-without-language-numbers-make-no-sense.html

    A bit of an older story, but I was quite impressed (as a robotics non-expert) by the movement in the video. To me it shows the power of the brain and the "eagerness" (lack of better word) at which it tries to exert some control in the world around it.

    Read this this morning in the train, what a story! Awesome guy, I wish him all the luck kicking against the established companies... Seems he has a bet with Elon Musk to outperform the current autonomous driving algoritms using his AI techniques. He is actually driving a lot with his car via Uber, to gain material to train his NN on :)

    Microsoft project Natick deploys cloud servers inside a vessel under seawater. A cool story about crossing competences of different people around an innovative solution. "In my experience the trick to innovating is not coming up with something brand new, but connecting things we've never connected before, pairing different technology together."

    It will depend on the alloys used, I am not sure but bainite might magnetic and I am not sure if nickel alloy based (stainless) steels can be processed at this low temperature... Metallurgist RF?

    "Pérez and his friends were astonished to see the unicorn herd. These creatures could be seen from the air without having to move too much to see them - they were so close they could touch their horns. While examining these bizarre creatures the scientists discovered that the creatures also spoke some fairly regular English. Pérez stated, "We can see, for example, that they have a common 'language,' something like a dialect or dialectic."

    Shocking. I assume that this could indeed have severe implications if it gets in the "wrong hands".

    "Feed it the first few paragraphs of a Guardian story about Brexit, and its output is plausible newspaper prose, replete with "quotes" from Jeremy Corbyn, mentions of the Irish border, and answers from the prime minister's spokesman." https://www.youtube.com/watch?time_continue=37&v=XMJ8VxgUzTc "Feed it the opening line of George Orwell's Nineteen Eighty-Four - "It was a bright cold day in April, and the clocks were striking thirteen" - and the system recognises the vaguely futuristic tone and the novelistic style, and continues with: "I was in my car on my way to a new job in Seattle. I put the gas in, put the key in, and then I let it run. I just imagined what the day would be like. A hundred years from now. In 2045, I was a teacher in some school in a poor part of rural China. I started with Chinese history and history of science." (https://www.theguardian.com/technology/2019/feb/14/elon-musk-backed-ai-writes-convincing-news-fiction)

    It's really lucky that it was OpenAI who made that development and Elon Musk is so worried about AI. This way at least they try to assess the whole spectrum of abilities and applications of this model before releasing the full research to the public.

    They released a smaller model, I got it running on Sandy. It's fairly straight forward: https://github.com/openai/gpt-2

    Why do we sleep? One answer could be: to clear waste products accumulated during the day. To prevent aging and neurodegeneration, the body must maintain homeostasis. What would happen if we experience chronic sleep loss? What would happen if microgravity impairs the cerebrospinal fluid to flush the brain? What would happen if cosmic radiations increase the amount of daily waste products?
