We have achieved a sustained calculation speed of 281 Tflops for the optimization of the 3-D structures of proteins from the X-ray experimental data by the Genetic Algorithm – Direct Space (GA-DS) method. In this calculation we used MDGRAPE-3, special-purpose computer for molecular simulations, with the peak performance of 752 Tflops. In the GA-DS method, a set of selected parameters which defi...
متن کامل28 . Particle detectors 1 28 . PARTICLE DETECTORS
In this section we give various parameters for common detector components. The quoted numbers are usually based on typical devices, and should be regarded only as rough approximations for new designs. More detailed discussions of detectors and their underlying physics can be found in books by Ferbel [1], Grupen [2], Kleinknecht [3], Knoll [4], and Green [5]. In Table 28.1 are given typical reso...

Beta vulgaris L. (sugar beet, table beet, mangel) is subject to a disease known as blackroot. Buchholtz and Meredith (1944:488) refer to the condition as tiprot, and earlier, Murphy (1927) called it rootburn of beets. Both Byford and Prince (1976) and W. C. Moore (1959) discussed the disease as “black leg.” In 1949(b) Ernould demonstrated that blackroot was not the same pathological condition a...

Approximately 40% of ischemic strokes have no clearly definable etiology and are termed cryptogenic strokes. Patent foramen ovale, a small communication between the left and right atria, is considered to be a risk factor for cerebral embolism. In this study, we report the case of a 29-year-old woman with diagnosis of ischemic stroke due to patent foramen ovale who has undergone percutaneous end...

The science of demography focuses on the drivers of population dynamics: fertility, mortality, and migration. Demography is inherently interdisciplinary and draws on theory from a range of social sciences, including sociology, economics, and anthropology. The demographers’ approach to fertility research at a given time is grounded in the contemporaneous fertility trends and fertility-related te...
