Potential-density pairs for bent bars

D. Vogt, P. S. Letelier

A method is presented to bend a thin massive line when the curvature is small. The procedure is applied to a homogeneous thin bar with two types of curvatures. One of them mimics a…

The Moran model as a dynamical process on networks and its implications for neutral speciation

Marcus A. M. de Aguiar, Yaneer Bar-Yam

In genetics the Moran model describes the neutral evolution of a bi-allelic gene in a population of haploid individuals subjected to mutations. We show in this paper that this mode…
