Abstract: We investigate the energy efficiency (EE) of multiple-input-multiple-output (MIMO) amplify-and-forward relaying networks relying on the realistic imperfect channel state information (CSI).

Abstract: Analysis of ac electrical systems can be performed via frame transformations in the time-domain or via harmonic transfer functions (HTFs) in the frequency-domain. The two approaches each ...

This article presents an overview of the derivation of effective shell-model Hamiltonian and decay operators within the framework of many-body perturbation theory, and discusses the results of ...

Center for Advanced High Magnetic Field Science, Graduate School of Science, Osaka University, Osaka, Japan. The spin polarization of a fractional quantum Hall state shows very interesting properties.

This approach allows one to explicitly determine whether an exciton is of Frenkel, Wannier, or some intermediate type. To illustrate how, we appeal to the formalism introduced by Wannier (2), who ...

Many fields of science and engineering require finding eigenvalues and eigenvectors of large matrices. The solutions can represent oscillatory modes of a bridge, a violin, the disposition of electrons ...
