Phase transitions: renormalization and scaling
(Vch Publ., 1995)
inverse wave scattering with discontinuous wave speed
(AIP Publishing, 1995-06)
The inverse scattering problem on the line is studied for the generalized Schrödinger equation (d 2ψ/dx 2)+k 2 H(x)2ψ=Q(x)ψ, where H(x) is a positive, piecewise continuous function with positive limits H ± as x → ±∞. This ...
Time-dependent dissipation in nonlinear Schrodinger systems
(AIP Publishing, 1995-03)
A coupled nonlinear Schrödinger–Poisson equation is considered which contains a time‐dependent dissipation function as a specific model of dissipation effects in nonlinear quantum transport theory and other areas. The ...
First-principles study of several hypothetical silica framework structures
(American Physical Society, 1995-09-15)
Several hypothetical silica structures have been generated using a simulated-annealing strategy with an ab initio based covalent-bonding potential. First-principles total-energy pseudopotential methods have been used to ...
Origin of scintillation in cerium_doped oxide crystals
(AIP Publishing, 1995-05)
We propose here a model of the scintillation from complex oxide single crystalsdoped with Ce3+ ions to explain the correlation observed between scintillation light yield and intrinsic luminescence of the matrix.
Computational simulation of type-II superconductivity including pinning phenomena
(American Physical Society, 1995-06-15)
A flexible tool, based on the finite-element method, for the computational simulation of vortex phenomena in type-II superconductors has been developed. These simulations use refined or newly developed phenomenological ...
REMARKS ON THE DISPERSION-RELATIONS USED TO CALCULATE DELTA-RHO
(American Physical Soc, 1995-06-01)
We use the operator product expansion (OPE) to show that nonperturbative QCD corrections to Δρ can be calculated using unsubtracted dispersion relations for either the transverse or the longitudinal vacuum polarization ...
Method for the conversion of cephalomannine to taxol and for the preparation of n-acyl analogs of taxol
(United States Patent and Trademark Office, 1995-11-28)
The natural product cephalomannine can be converted to the important anticancer natural product taxol by a simple process involving the steps of dihydroxylation to give cephalomannine-diols, diol cleavage, benzoylation at ...
