4:47 pm	From a workshop on role of theory in design automation "One of the recurrent themes of the discussion is: we have SAT solvers that seem to work on all examples we try them on. How does this fit with the conventional wisdom that P not equal to NP? This is a very interesting open problem, that we should work on in the future." from http://rjlipton.wordpress.com/2009/07/09/nsf-workshop-summary/ via rjlipton (4 Comments |Comment on this)

4:58 pm	Anti-angiogenesis drugs :-( I still remember time when great hopes in anti-cancer therapy were raised in connection with drugs blocking formation of new blood vessels. And (as it is often the case) the results in mice were great.Then the hopes dimmed, and the controversial approval of Avastin by FDA in 2008 against the recommendation of its advisory panel underscored the fact that the advances were quite marginal (the panel objected because for that class of tumors Avastin only slowed tumor growth but failed to extend survival): http://en.wikipedia.org/wiki/Bevacizumab Here is an article which seems to shed some light on why the "magic bullet" does not quite work: http://scienceblog.cancerresearchuk.org/2009/03/22/anti-angiogenesis-drugs/ ( summary ) (Comment on this)

11:56 am	The Boston Globe to close? "The New York Times Co. said last night that it is notifying federal authorities of its plans to shut down the Boston Globe." via http://althouse.blogspot.com/2009/05/death-of-boston-globe.html upd: probably not, this is just a labor dispute. (Comment on this)

3:12 pm	Scanning laser ophthalmoscopy Now the eye exam can be made without eye drops which dilate the pupils, so one can read or drive afterwards. Another good thing is that the resulting pictures are stored, so it is possible to track the changes over the years. And the pictures are pretty cool and resemble some of pictures obtained from space telescopes, which is not so surprising, since the same methods of adaptive optics are used: http://www.totalfamilyeyecare.com/optos.htm http://en.wikipedia.org/wiki/Scanning_laser_ophthalmoscopy ( downsides ) (5 Comments |Comment on this)

4:58 pm	D. Gabor, Associative Holographic Memories I recently found a very cool short paper (4 pages) which Dennis Gabor written 40 years ago. It explains the math of associative holographic memory, which turns out to be very simple. Because it is that simple, neither holograms, nor even waves and oscillations, are actually necessary to implement this scheme of associative memory. D. Gabor, Associative Holographic Memories, IBM Journal of Research and Development, 13(2), 156-159 (1969). Abstract, PDF (8 Comments |Comment on this)

So the entropy of the whole system is less then the entropy of the two coordinates added together, and the amount by which it is less is exactly the mutual information: Imutual = S[X] + S[Y] - S[X, Y].

3:23 pm	"Towards a Neurobiological Theory of Consciousnes" Recently, I reread a number of papers in neuro. The one I liked the most is "Towards a Neurobiological Theory of Consciousness" by Francis Crick and Christof Koch in Seminars in the Neurosciences (1990), Volume 2, pages 263–275: http://profiles.nlm.nih.gov/SC/B/C/F/D/_/scbcfd.pdf ( a bit about this paper ) I hope the next year will be better than the outgoing one... Good luck in the New Year! (8 Comments |Comment on this)

5:41 pm	Дмитрий Крымов Одно из самых интересных московских впечатлений -- двойной спекталь Дмитрия Крымова в Школе Драматического Искусства на Сретенке, "Родословная" и "Шостакович": http://info.sdart.ru/item/603 "Родословная" -- особенно яркая. Название "спектакль" или "театр" применимо к тому, что он делает, довольно условно, поскольку он использует элементы разных жанров, и у меня нет впечатления, что драматургия -- основная компонента, а остальные -- вспомогательные. Если верить их сайту, то у них еще есть билеты на 14-17 декабря и 24-26 января.. Еще я видел очень яркую выставку Оскара Рабина в филиале Третьяковки около Парка Культуры, но она уже кончилась..

10:25 pm	Laser weapons are here Northrop Grumman says its new 15kW FIRESTRIKE continuous fire solid-state laser is ready for orders by US military services. A 400lb relatively compact device, can be combined into a 100kW battery, continuous run-time as long as power and coolant are provided, "designed as a line replaceable unit (LRU) for battlefield applications". "Energy efficiency for Northrop's chains is supposedly in the 20 per cent region. This suggests that a full-bore 100kW battle ray will weigh about 1.5 tonnes and require half a megawatt of power.. within the ballpark for modern combat vehicles."

2:04 pm	John Ioannidis: round 2 http://www.economist.com/science/displaystory.cfm?story_id=12376658 "With so many scientific papers chasing so few pages in the most prestigious journals, the winners could be the ones most likely to oversell themselves—to trumpet dramatic or important results that later turn out to be false. This would produce a distorted picture of scientific knowledge, with less dramatic (but more accurate) results either relegated to obscure journals or left unpublished." "Dr Ioannidis made a splash three years ago by arguing, quite convincingly, that most published scientific research is wrong." http://medicine.plosjournals.org/perlserv/?request=get-document&doi=10.1371/journal.pmed.0020124 http://medicine.plosjournals.org/perlserv/?request=get-document&doi=10.1371%2Fjournal.pmed.0050201 (2 Comments |Comment on this)

2:12 am	Новый Пелевин Мне нравится новый сборник Пелевина, (который с оскорбительным названием -- "П5"), хотя многие в ленте жалуются, что "скучно, и хуже, чем раньше, и не то (или, наоборот, повторение)". У меня от него ощущение гораздо большего реализма, по сравнению с предыдущими текстами, и гораздо большей сфокусированности, сдержанности и ясности каждого рассказа в том, что касается изложения философского ядра..

12:17 pm	Terrence Sejnowski speaks at MIT Friday, Nov 7 2008, 4pm, MIT 46-3002 Terrence J. Sejnowski Google Brain "The brain is not just a computing device: It is also a powerful communication network, with the total bandwidth of signaling between neurons comparable to that of the entire World Wide Web. How is all the traffic between brain areas regulated? How does the brain store and retrieve information? The answers to these questions are being sought in the temporal coherence of brain signals on a global scale. Curiously, brain states with the highest coherence are found during sleep".
