Although the prevalence of canine hip dysplasia (HD) has been the subject of a number of published studies, estimates vary widely. This study evaluated several possible causes for these differences. Sixty Belgian, Dutch and German veterinarians were

This book gives an account of a number of recent developments in two different subfields of research, optics and micro--electronics. The leading principle in presenting them together in one book is the striking similarity between a variety of notions

Plasmon energies are closely related to the complex zeros of the determinant of the dielectric matrix or, equivalently, to the complex poles of the dynamically screened interaction matrix of electronic systems. In this paper we first clarify the true

Stopping powers for channeled He ions have been calculated with a modified version of the Monte Carlo code LAROSE [J.H. Barrett, Phys. Rev. B 3 (1971) 1527]. The spatial distribution of the valence electron density in Si was obtained from bandstructu

Connection rules for envelope functions are formulated in terms of a transfer matrix, the elements of which are calculated using a scattering-matrix approach based on empirical pseudopotentials. We propose a 6\ifmmode\times\else\texttimes\fi{}6 trans

A method to calculate electronic wavefunctions and energies in AlGaAs heterostructures is developed and applied to some typical configurations. The method is based on the use of empirical pseudopotentials and the applicability of the flat-band approx

Connection rules for envelope functions related to the Γ- and X-point conduction-band valleys in GaAs/Al(Ga)As systems are formulated in terms of a transfer matrix. The transfer-matrix elements are calculated using a method in which wave functions,

As a continuation of earlier work, we present the results of a local-density-approximation-based calculation of some dielectric properties of silicon. In particular, we have calculated the plasmon-resonance line shape for k\ensuremath{\rightarrow}0 a

L'exactitude de l'approximation GW est etudiee en evaluant les contributions du plus bas ordre du vertex a la bande interdite d'energie des semiconducteurs covalents. Une analyse des differentes contributions diagrammatiques montre qu'il y a deux pro
