The Bulk-Edge Correspondence for Disordered Chiral Chains

We study one-dimensional insulators obeying a chiral symmetry in the single-particle picture. The Fermi level is assumed to lie in a mobility gap. Topological indices are defined for infinite (bulk) or half-infinite (edge) systems, and it is shown that for a given Hamiltonian with nearest neighbor hopping the two indices are equal. We also give a new formulation of the index in terms of the Lyapunov exponents of the zero energy Schr\"odinger equation, which illustrates the conditions for a topological phase transition occurring in the mobility gap regime.Comment: 20 pages, 3 figure

The Inverse U-shaped religion–health connection among Israeli Jews

A growing body of evidence indicates an association between religion and health. However, few have studied the connection between the extent of an individual's religiosity and his health. Analysis of the 2004 Israel National Health Survey was performed. Religiosity was self-identified using five continuous categories, distinctive to Israeli Jews. Bivariate and multivariate analyses examined the relationship between the extent of Religious commitment and several health outcomes. The relationship took the shape of an inverse U function: Israeli Jews in the middle religiously have the worst physical and mental health status on both unadjusted and adjusted bases. Israeli Jews exhibit a non-trivial connection between religiosity and health whereby the most Secular and the most Religious individuals seem to be healthier than individuals in between
