Characterizing the nature of the adaptive process at the genetic level is a central goal for population genetics. In particular, we know little about the sources of adaptive substitution or about the number of adaptive variants currently segregating in nature. Historically, population geneticists have focused attention on the hard-sweep model of adaptation in which a de novo beneficial mutation...

Carbohydrate recognition is a phenomenon critical to a number of biological functions in humans including highly specific responses of the immune system and the selective synthesis of functional proteins. Unlike polypeptides and proteins, oligosaccharides have been observed to have dynamic properties with extensive ability to occupy different conformations over time and space. Understanding the...

Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...

The full-domain “sweep,” in which all angular fluxes in a problem are calculated given previous-iterate values only for the volumetric source, forms the foundation for many iterative methods that have desirable properties [1]. One important property is that iteration counts do not grow with mesh refinement [1]. The sweep solution on parallel machines is complicated by the dependency of a given ...
