Transport, stability and plasma control studies in the TJ-II stellarator
(Institute of Physics Publishing, 2015-07)
The main TJ-II results since 2012 are presented in this overview. Impurity confinement is studied showing an isotopic dependence of impurity confinement time, asymmetries in parallel impurity flows in TJ-II ion-root plasmas ...
Numerical study of the spherically symmetric Gross-Pitaevskii equation in two space dimensions
(2000-08-01)
The Gross-Pitaevskii equation for Bose-Einstein condensation (BEC) in two space dimensions under the action of a harmonic oscillator trap potential for bosonic atoms with attractive and repulsive interparticle interactions ...

Firing sequence storage using inhibitory synapses in networks of pulsatil nonhomogeneous integrate-and-fire neural oscillators
(2002)
We discuss a nonhomogeneous population of pulsatil integrate-and-fire neural oscillators, coupled through purely inhibitory synapses. For instantaneous communication, we provide a strategy to generate synaptic couplings ...
H-bond simulation in DNA using a harmonic oscillator isospectral potential
(1997-12-01)
A harmonic oscillator isospectral potential obtained by supersymmetric algebra applied to quantum mechanics is suggested to simulate DNA H bonds. Thermic denaturation is studied with this potential.
Deformed Gaussian orthogonal ensemble and the statistical fluctuations in the spectra of the quartic oscillator
(1999-12-01)
The nearest-neighbor spacing distributions proposed by four models, namely, the Berry-Robnik, Caurier-Grammaticos-Ramani, Lenz-Haake, and the deformed Gaussian orthogonal ensemble, as well as the ansatz by Brody, are applied ...
Diurnal variations in insulin secretion and K+ permeability in isolated rat islets

High temperature mechanical behavior of plasma-nitrided inconel 625 superalloy
(2017-01-01)
INCONEL 625 nickel-based superalloys present limitations for use at temperatures above 600 °C. For this reason, protective coatings can be used as barriers to avoid both nucleation and crack propagation. The aim of this ...
