The global-in-time existence of bounded weak solutions to a large class of physically relevant, strongly coupled parabolic systems exhibiting a formal gradient-flow structure is proved. The main feature of these systems is that the diffusion matrix may be generally neither symmetric nor positive semidefinite. The key idea is to employ a transformation of variables, determined by the entropy den...

What mathematicians, scientists, engineers, and statisticians mean by \inverse problem" di ers. For a statistician, an inverse problem is an inference or estimation problem. The data are nite in number and contain errors, as they do in classical estimation or inference problems, and the unknown typically is in nite-dimensional, as it is in nonparametric regression. The additional complication i...

This study addresses an important but neglected topic by investigating the role of women entrepreneurship in the economy. The purpose is twofold. First, based on published research, we have tried to estimate the economic impact of women entrepreneurship. Second, based on this assessment of the current state and in comparison with our needs to better understand this topic, we suggest a number of...
