We study, in various special cases, total distributions on the product of a finite collection of finite probability spaces and, in particular, the question of when the probability distribution of each factor space is determined by the total

The word “researcher” is loaded and often confusing. It takes years to become one and to master all of its aspects. In this paper, we investigate whether or not this process of “becoming” can be catalyzed through education. The focus will be on wireless communications, though the same principle could very well be replicated to other disciplines.

The analog of Toupin's version of Saint-Venant's principle is proved for an isotropie, linear elastic mieropolar body of arbitrary length and of uniform cross-section which in the unstressed state is helical. That is, when such a body is loaded by self-equilibrated stresses and couple stresses at one end only, we show that the elastic strain energy stored in the part of the body beyond a certai...

epidermal growth factor (egf) is an important factor for healing after tissue damage in diverse experimental models. it plays an important role in liver regeneration (lr). the objective of this experiment is to investigate the methylation variation of 10 cpg sites in the egf promoter region and their relevance to egf expression during rat liver regeneration. as a follow up of our previous study...

ÐEstrogens can in ̄uence the survival, plasticity and function of many adult neurons. Many of these effects, such as neurite outgrowth and increased dendritic spine density, are mediated by changes in neuronal cytoskeletal architecture. Since neuro®lament proteins play a key role in the maintenance and remodeling of the neuronal cytoskeleton, we postulated that changes in neuro®lament light chai...
