State vocational rehabilitation (VR) agencies provide important employment services for people with disabilities. Yet little is known about the characteristics of individuals who have received VR services compared to the general population of people with disabilities. Using 2007 data, we found...

The parametric motion of one-electron energy levels of disordered systems near the Anderson localization transition is studied. We perform numerical calculations of the distributions of the first (level velocity) and the second (level curvature) derivatives with respect to a change of boundary...

During the past decade or so there has been growing theoretical, numerical and experimental support for the Bohigas-Giannoni-Schmit conjecture 1984 on the applicability of the random matrix theories statistics (GOE, GUE) in the classically ergodic quantal Hamiltonian systems. In the classically...
