A review with 184 refs. The authors review the principles of the Car-Parrinello method for ab initio mol. dynamics (AIMD) simulations by first outlining the foundations of the method based on d. functional theory, plane wave basis sets and pseudopotentials ...
The theory of single-transition cross-polarization in NMR is presented and verified by exptl. evidence. In comparison to conventional cross-polarization a qual. change in the mechanism is obsd. Under the influence of matched radiofrequency fields with ampl ...
The absorption of power is studied with fluid and gyrokinetic plasma models, when Alfven resonances provide for a weak damping in a partially standing wave field. Examples chosen in slab and toroidal geometry show that the fluid predictions based on resona ...
A new scenario to delay or prevent neoclassical tearing mode (NTM) onset is presented. By active sawtooth destabilization, short period and low amplitude sawteeth are generated, such that the sawtooth produced NTM seed island is reduced and the threshold n ...
A comprehensive study on the effect of a lossy ground on the induced voltages on overhead power lines by a nearby lightning strike is presented. The ground conductivity plays a role in both the evaluation of the lightning radiated fields and of the line pa ...
This paper is concerned with the development of a general framework for adaptive mesh refinement and coarsening in three-dimensional finite-deformation dynamic-plasticity problems. Mesh adaption is driven by a posteriori global error bounds derived on the ...
A large CdTe-based tomographic system has been installed two years ago on the TORE SUPRA tokamak, for a detailed investigation of the dynamics of fast electrons generated by radio-frequency waves in Fusion plasmas, as a function of time, space and energy. ...
We estimated total arterial compliance (C) in eight anesthetized mongrel dogs with (i) the area method (AM), (ii) the pulse pressure method (PPM), and (iii) the stroke volume-to-pulse pressure ratio (SV/PP). Average compliance was C(AM)=1.1+/-0.73 ml mm Hg ...
We investigate the nonlinear drift response of electrons in Si, GaAs, and InP crystals to high-power electromagnetic waves by means of a Monte Carlo technique, with the aim of developing an efficient frequency converter for 1 THz output radiation. Drift ve ...
Using angle-resolved photoemission and linearly polarized synchrotron radiation, we measured the electronic band structure of electronic states of CuO2 plane materials ranging from insulators (Sr2CuO2Cl2) to overdoped superconductors (Bi2Sr2CaCu2O8+x). We ...
