15 صفحه اولThe Origin of Soft X-rays in Dq Herculis
DQ Herculis (Nova Herculis 1934) is a deeply eclipsing cataclysmic variable containing a magnetic white dwarf primary. The accretion disk is thought to block our line of sight to the white dwarf at all orbital phases because of its extreme inclination angle. Nevertheless, soft X-rays were detected from DQ Her with the ROSAT PSPC. To probe the origin of these soft X-rays, we have performedChandr...
متن کاملEvolutionary principles and their practical application
Evolutionary principles are now routinely incorporated into medicine and agriculture. Examples include the design of treatments that slow the evolution of resistance by weeds, pests, and pathogens, and the design of breeding programs that maximize crop yield or quality. Evolutionary principles are also increasingly incorporated into conservation biology, natural resource management, and environ...
متن کاملSuccessive Determination and Verification of Polytopes by their X-Rays
It is shown that each convex polytope P in E can be verified by ([d/(d— k)]+ 1) /odimensional X-rays. This means that P is uniquely determined by these X-rays and the choice of the direction of each X-ray depends only on P. Examples are constructed to show that in general this number cannot be reduced. Further, it is shown that each convex polytope P in E can be successively determined by only ...
