Many studies on humans have been published comparing psychophysic and electroretinographic (ERG) adaption to dark. In both cases, there is evidence of a break commonly called "alpha point"; such a break occurs when the subject has first been exposed to an adequate previous bleaching. Jayle has summarized this problem extremely well.1-2 In these publications dealing with the electroretinographic...

This supplementary material presents details of the experiments addressed in the main paper. Results for individual steps of the pot configuration pipeline are illustrated for real and synthetic datasets. Four experiments show the reassembly of a computer generated axially symmetric pot from 10, 17, 23 and 30 unorganized broken pieces, respectively. Gaussian noise was added to make the problem ...

The Ku70/Ku80 heterodimer, or Ku, is the central component of the nonhomologous end joining (NHEJ) pathway of double strand break (DSB) repair. Because Ku forms a ring through which the DSB threads, it likely becomes topologically attached to DNA during repair. The mechanism for its removal was unknown. Using a method to identify proteins recruited to DSBs in Xenopus laevis egg extract, we show...

Visual recognition of patterns is a basic capability of most advanced species in nature. A big percentage of the human brain is devoted to visual processing with a substantial portion of this area used for pattern recognition. Visual pattern recognition enables a variety of tasks such as object and target recognition, navigation, grasping and manipulation, among others. Advances in camera techn...

I n most industrialized economies inflation tends to be pro-cyclical; that is, inflation is high during times of high economic activity. When economic activity is measured by the unemployment rate this statistical relationship is known as the Phillips curve. The Phillips curve is sometimes viewed as a menu for monetary policymakers, that is, they can choose between high inflation and low unempl...

Abstract Ductile fracture is characterized by a large amount of deformation. Two mechanisms may lead to ductile failure: local tearing appear in front stress concentration region like crack or geometry changes weak part the structure can induce global collapse structure. For cracks such as those considered Leak Before Break studies, analyses and net-section criteria have been used. The present ...
