Pulse trains propagating through excitable media subjected to external noise

Beato, V.; Engel, H.; Schimansky-Geier, L. - In: The European Physical Journal B - Condensed Matter and … 58 (2007) 3, pp. 323-329

We study the propagation of periodic pulse trains in excitable media exposed to external spatio-temporal noise using … weak noise approximation we find noise-induced transitions in the dispersion relation of pulse trains. We discuss noise …-enhanced propagation of pulse trains within a certain wave-length range caused by external noise of moderate strength. Copyright EDP …

Can a few fanatics influence the opinion of a large segment of a society?

Stauffer, D.; Sahimi, M. - In: The European Physical Journal B - Condensed Matter and … 57 (2007) 2, pp. 147-152

Models that provide insight into how extreme positions regarding any social phenomenon may spread in a society or at the global scale are of great current interest. A realistic model must account for the fact that globalization, internet, and other means of mass communications have given rise to...

Long-range effects on superdiffusive algebraic solitons in anharmonic chains

Brunhuber, C.; Mertens, F. G.; Gaididei, Y. - In: The European Physical Journal B - Condensed Matter and … 57 (2007) 1, pp. 57-65

Studies on thermal diffusion of lattice solitons in Fermi-Pasta-Ulam (FPU)-like lattices were recently generalized to the case of dispersive long-range interactions (LRI) of the Kac-Baker form. The variance of the soliton position shows a stronger than linear time-dependence (superdiffusion) as...

Systems driven by Poisson-distributed quantal inputs can be described as “shot noise” stochastic processes. This … longer be described by classical shot noise processes. Here, we show that explicit expressions for various statistical … temporal correlations and the statistics of fluctuations. Multi-channel shot noise processes, therefore, open a way to deduce …
