The pdf of price changes was not Gaussian plus outliers, as previously believed. Rather, all the data-including data previously termed outliers-conformed to a single pdf encompassing both everyday fluctuations and &#8220;once in a century&#8221; fluctuations. Instead of a Gaussian or some correction to a Gaussian, they found a power law pdf with exponent -4, a sufficiently large exponent that the difference from a Gaussian is not huge&quot;<\/div>\n<div class=\"delicious-tags\">(tags: <a href=\"https:\/\/delicious.com\/dabacon\/finance\">finance<\/a> <a href=\"https:\/\/delicious.com\/dabacon\/powerlaws\">powerlaws<\/a>)<\/div>\n<\/li>\n<li>\n<div class=\"delicious-link\"><a href=\"http:\/\/physics.aps.org\/synopsis-for\/10.1103\/PhysRevA.79.012332?referer=rss\">Physics &#8211; Relaxing the requirements for scalable quantum computing<\/a><\/div>\n<div class=\"delicious-extended\">&quot;In a paper appearing in Physical Review A, Panos Aliferis, who is at the IBM Watson Research Center, and John Preskill of the California Institute of Technology, rigorously establish a lower bound for the fault-tolerance threshold for one of Knill&#8217;s constructions that has relatively small overhead requirements.
