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 ...
Comment on the Dispersion Relations used to Calculate Δρ
(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 ...
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 ...
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 ...
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.
Sediment-Water Column Oxygen and Nutrient Fluxes in Nearshore Environments of the Lower Delmarva Peninsula, USA
Sediment-water column exchanges of oxygen, dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP) were measured in situ over an annual cycle for sandy and silt-clay sediment types in a shallow Chesapeake ...
Non-nested Model Selection/Validation: Making Credible Postsample Inference Feasible
(Virginia Tech, 1995-04)
Effective, credible inference with respect to the postsample forecasting performance of time series models is widely held to be infeasible. Consequently, the model selection and Granger-causality literatures have focussed ...
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 ...
