urn:hdl:2445/18738 Pulse propagation sustained by noise in arrays of bistable electronic circuits Bascones, Roberto García Ojalvo, Jordi Sancho, José M. Física matemàtica Física estadística Termodinàmica Sistemes dinàmics diferenciables Mathematical physics Statistical physics Thermodynamics Differentiable dynamical systems One-dimensional arrays of nonlinear electronic circuits are shown to support propagation of pulses when operating in a locally bistable regime, provided the circuits are under the influence of a global noise. These external random fluctuations are applied to the parameter that controls the transition between bistable and monostable dynamics in the individual circuits. As a result, propagating fronts become destabilized in the presence of noise, and the system self-organizes to allow the transmission of pulses. The phenomenon is also observed in weakly coupled arrays, when propagation failure arises in the absence of noise. 2011-07-07T12:51:39Z 2011-07-07T12:51:39Z 2002 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: http://dx.doi.org/10.1103/PhysRevE.65.061108 Physical Review E, 2002, vol. 65, núm. 6, p. 061108(1)-061108(5) http://dx.doi.org/10.1103/PhysRevE.65.061108 (c) The American Physical Society, 2002 info:eu-repo/semantics/openAccess The American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
