20.500.12556/DKUM-26044 Stochastic resonance on excitable small-world networks via a pacemaker We show that the correlation between the frequency of subthreshold pacemaker activity and the response of an excitable array is resonantly dependent on the intensity of additive spatiotemporal noise. Thereby, the effect of the underlying network, defining the interactions among excitable units, largely depends on the coupling strength. Only for intermediate coupling strengths is the small world property able to enhance the stochastic resonance, whereas for smaller and larger couplings the impact of the transition from diffusive to random networks is less profound. Thus, the optimal interplay between a localized source of weak rhythmic activity and the response of the whole array demands a delicate balance between the strength of excitation transfer and the effectiveness of the network structure to support it. stochastic resonance small-world networks cardiology neurophysiology nonlinear dynamical systems spatiotemporal phenomena stohastična resonanca mali-svet mreže kardiologija nevrofiziologija nelinearni dinamični sistemi prostorsko-časovni pojavi true true false Angleški jezik Angleški jezik Neznano 2012-05-31 11:46:02 2012-05-31 11:46:03 2022-04-15 03:40:44 2023-12-31 03:25:10 2007 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.2 12064534 1539-3755 URN:SI:UM:DK:UGEPC3ZR http://dx.doi.org/10.1103/PhysRevE.76.066203 1 https://dk.um.si/Dokument.php?lang=slv&id=34958 Fakulteta za naravoslovje in matematiko 0 0 0
