Análisis no lineal de las juntas entre grandes paneles prefabricados de hormigón
(1985)
Article
Accés obertEn el presente artículo se estudian las uniones entre grandes paneles de hormigón armado, cuando éstas se conforman por dientes y se cosen por armaduras. Además se estudia el caso de que estén sometidas a acciones a lo ... -
Control of electrical turbulence by periodic excitation of cardiac tissue
(Institute of Physics (IOP), 2017-11-01)
Article
Accés obertElectrical turbulence in cardiac tissue is associated with arrhythmias such as life-threatening ventricular fibrillation. Recent experimental studies have shown that a sequence of low-energy electrical far-field pulses is ... -
Differential susceptibility to noise of mixed Turing and Hopf modes in a photosensitive chemical medium
(2007-12-31)
Article
Accés obertWe report on experiments with the photosensitive chlorine dioxide-iodine-malonic acid reaction (CDIMA) when forced with a random (spatiotemporally) distributed illumination. Acting on a mixed mode consisting of oscillating ... -
Dynamics of reaction-diffusion patterns controlled by asymmetric nonlocal coupling as a limiting case of differential advection
(2014-05-14)
Article
Accés obertA one-component bistable reaction-diffusion system with asymmetric nonlocal coupling is derived as a limiting case of a two-component activator-inhibitor reaction-diffusion model with differential advection. The effects ... -
Estimation of synaptic conductances in presence of nonlinear effects caused by subthreshold ionic currents
(2017-07)
Article
Accés obertSubthreshold fluctuations in neuronal membrane potential traces contain nonlinear components, and employing nonlinear models might improve the statistical inference. We propose a new strategy to estimate synaptic conductances, ... -
Nonlinear analysis of interconnected power converters: a case study
(2015-09-01)
Article
Accés obertIn this paper the nonlinear dynamics of interconnected power converters in an islanded direct current (DC) microgrid is analyzed. By using a simplified scheme based on two cascaded converters we analyze the dynamical ... -
Nonlinear physics of electrical wave propagation in the heart: a review
(2016-08-12)
Article
Accés obertThe beating of the heart is a synchronized contraction of muscle cells (myocytes) that are triggered by a periodic sequence of electrical waves (action potentials) originating in the sino-atrial node and propagating over ... -
Respuesta no lineal de estructuras de hormigón armado con evidencia de fenómenos de interacción suelo-cimentación-estructura (ISE)
(2018-11-01)
Report de recerca
Accés restringit per decisió de l'autorLa modificación del cortante basal de diseño de las estructuras con efectos de interacción suelo-estructura (ISE) en los procedimientos de fuerza lateral equivalente posee una deficiencia significativa, y tiene que ver con ... -
Surfactant-induced gradients in the three-dimensional Belousov-Zhabotinsky reaction
(2011-11-10)
Article
Accés obertScroll waves are prominent patterns formed in three-dimensional excitable media, and they are frequently considered highly relevant for some types of cardiac arrhythmias. Experimentally, scroll wave dynamics is often studied ... -
Twists of opposite handedness on a scroll wave
(American Institute of Physics (AIP), 2013-06-05)
Article
Accés obertThe dynamic interaction of scroll waves in the Belousov-Zhabotinsky reaction with a vertically orientated gradient of excitability is studied by optical tomography. This study focuses on scroll waves, whose filaments were ...
