We show that the layered-structure BaCuS 2 is a moderately correlated electron system in which electronic structure of CuS layer bears resemblance to those both cuprates and iron-based superconductors. Theoretical calculations reveal in-plane d – p ? * -bonding bands are isolated near Fermi level. As energy separation between orbitals much smaller than superconductors, expected be correlated. s...

among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
| This paper presents a realistic modeling framework for evaluating the performance of location management schemes in PCS networks. The framework captures complex human behaviors and has been validated through analysis of actual call and mobility data. Simulation results, showing the performance of IS-41, are presented.
