We study the effects of hydrostatic pressure over the ground state binding energy of light hole excitons confined in GaAs − Ga1−xAlxAs spherical quantum dots. We applied the variational method using 1s-hydrogenic wavefunctions, in the framework of the effective mass approximation. We computed the exciton binding energy as a function of the dot radius, Al concentrations and pressures. Our result...

in this paper, we study the plasmonic thermal conductance of ordered stacks of metallic nanorings in a host material. using second quantized formalism of the random phase approximation, we first determine the dispersion relations of surface plasmon waves on the stacks of nanorings. then, using landauer-buttiker formalism, we determine the coefficient of plasmonic thermal conductance and heat cu...

We develop a formalism for the calculation of the ground state energy of a spinor field in the background of a cylindrically symmetric magnetic field. The energy is expressed in terms of the Jost function of the associated scattering problem. Uniform asymptotic expansions needed are obtained from the Lippmann-Schwinger equation. The general results derived are applied to the background of a fin...

INTRODUCTION Osteomyelitis of the radius resulting in the radial clubhand is a very rare condition and few studies have been published about its prognosis and treatment. CASE OUTLINE This is a case report of hematogenous osteomyelitis of the radius with a complete loss of the radius leaving only the distal radial metaphysis to carry the carpus. In order to achieve best functional results, fou...

Aiming at three-dimensional space localization problem in wireless sensor network, a method of three-dimensional centroid algorithm with spherical perception radius (3DCSPR) is proposed. The algorithm uses Gaussian probability density function to estimate the sensor node radius, and uses tetrahedron method and three-dimensional center to locate unknown node with estimated. Firstly, RSSI value b...

The Erlang capacity per cell and per unit area in urban code-division multiple-access (CDMA) microcellular environments is evaluated. Special emphasis is given to the effect of breakpoint distance and cell size on the system Erlang capacity. Two different cell plans are considered in which the communication between the base station (BS) and the mobile unit always occurs in a line-of-sight (LOS)...

Nonlinear thermal convection in a fast rotating annulus about its axis, with slightly inclined ends, radial gravity and heating, is studied numerically for a fluid of Prandtl number sigma=0.7 and different values of the radius ratio and rotation rate. The properties of the rotating waves that appear after the Hopf bifurcation of the conductive state are analyzed. Near the critical Rayleigh numb...

we give further results for perron-frobenius theory on the numericalrange of real matrices and some other results generalized from nonnegative matricesto real matrices. we indicate two techniques for establishing the main theorem ofperron and frobenius on the numerical range. in the rst method, we use acorresponding version of wielandt's lemma. the second technique involves graphtheory.

1. A study has been made of the diffusion and filtration of a graded series of molecules (including tritium-labelled water, urea, glucose, antipyrine, sucrose, raffinose, and hemoglobin) in aqueous solution through porous cellulose membranes of three degrees of porosity. 2. Experimental results were in close agreement with predictions based on the membrane pore theory of Pappenheimer et al. (1,...
