The stability of internal, ideal modes in tokamaks with low magnetic shear in the plasma core is analyzed. For equilibria with large aspect ratio, a parabolic pressure profile and a flat q profile in the core, an exact solution of the ideal magnetohydrodyn ...
Metastable lime-of-flight (TOF) spectroscopy was used to measure the translational energy distribution of specific rotational states of CO formed from ketene photodissociation (CH2CO-->CH2+CO) at 351 nm. This distribution could be directly related to the i ...
We propose a new scheme to systematically design optimized connection atoms for arbitrary quantum mechanics/mol. mechanics (QM/MM) boundaries: the pseudopotential of the boundary atom is optimized such that it minimizes the errors in the electronic structu ...
Coding strategies that exploit node cooperation are developed for relay networks. Two basic schemes are studied: the relays decode-and-forward the source message to the destination, or they compress-and-forward their channel outputs to the destination. The ...
An improvement over classical dynamic feedback linearization for the control of a nonholonomic mobile robot is proposed. The use of a state extension of higher dimension than in the case of dynamic feedback linearization helps reject constant disturbances ...
It is shown that a strong but diffuse dielectric anomaly, commonly expected only in disordered ferroelectrics, may be inherent in strained and defect-free perovskite ferroelectric thin films. The origin of this unusual anomaly, which was never predicted fo ...

In a recent work [Laio, A., VandeVondele, J., Rothlisberger, U. J. Phys. Chem. B 2002 106, 7300] a novel method has been proposed to define dynamical electrostatic potential derived (D-RESP) charges for systems described within a quantum mechanics/mol. mec ...
The equipartition problem on an undirected graph G=(V,E) with n nodes and a system of edge weights, is to find a subset of [n/2] nodes such as the associate cut has a smallest cost. We present a polynomial algorithm to solve the equipartition problem on a ...
