The basic difference equations for biased correlated walks on an infinite line are solved by means of the Fourier-Laplace techniques. In terms of these solutions the discrete Laplace transforms of first-passage probabilities ...

Experimentally it is found that the pressure dependence of T-c, in high-T-c superconductors, is influenced by several factors. The carrier density, the doping, and the contraction of the unit cell are some of these factors. ...

We investigated the electronic structure of the RNiSn (R=La,Ce,Pr,Nd) intermetallic compounds as well as their corresponding mono- and dihydrides. We computed the energy bands and the total and partial densities of states ...

Differential and total cross sections for the production of N+ fragment formed by the collision of N-2(+) on He and Ar, at projectile energies between 1.0 and 5.0 keV and for scattering angles from -4 degrees to 4 degrees ...

Neutral products from dissociative collisions of triatomic hydrogen like ions incident on He atoms were studied. Absolute differential and total cross sections are reported in the energy range of 1.25 and 5.00 keV for ...

We investigated the adsorption of carbon monoxide on the MgO(100), MgO(100):Ni, and MgO(100):Cr surfaces, using an ab initio density functional cluster embedding approach. The relaxation and rumpling of the MgO surface ...

The bound eigenfunctions and spectrum of a Dirac hydrogen atom are found takmg advantage of the SU(1, 1) Lie algebra in which the radial part of the problem can be expressed. For defining the algebra we need to add to the ...

We present differential scanning calorimetry (DSC) and in situ Mossbauer spectroscopy results for Metglas ribbons, to which different heat treatments were made. The Curie temperature of the amorphous phase is determined ...

We study in this paper, using asymptotic techniques, the laminar film condensation process of a forced flow characterized by saturated vapor in contact with one lateral surface of a thin plate. The other lateral surface ...

In this article the steady-state process leading to ignition of a combustible mixture of hydrogen, oxygen, and nitrogen by a hot flat plate in a boundary layer flow is studied, including the effect of thermal diffusion. ...
