20.500.12556/DKUM-35346 Topologically determined optimal stochastic resonance responses of spatially embedded networks We have analyzed the stochastic resonance phenomenon on spatial networks of bistable and excitable oscillators, which are connected according to their location and the amplitude of external forcing. By smoothly altering the network topology from a scale-free (SF) network with dominating long-range connections to a network where principally only adjacent oscillators are connected, we reveal that besides an optimal noise intensity, there is also a most favorable interaction topology at which the best correlation between the response of the network and the imposed weak external forcing is achieved. For various distributions of the amplitudes of external forcing, the optimal topology is always found in the intermediate regime between the highly heterogeneous SF network and the strong geometric regime. Our findings thus indicate that a suitable number of hubs and with that an optimal ratio between short- and long-range connections is necessary in order to obtain the best global response of a spatial network. Furthermore, we link the existence of the optimal interaction topology to a critical point indicating the transition from a long-range interactions-dominated network to a more lattice-like network structure. physics stochastic resonance complex networks fizika stohastična resonanca kompleksne mreže true true true IOP Publishing Angleški jezik Slovenski jezik Znanstveno delo 2012-06-07 10:40:57 2012-06-07 10:40:59 2025-05-29 13:13:08 2021-04-14 03:55:31 2011 0 0 str. 1-16 št. 1 Letn. 13 2011 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 2010-10-03 2011-01-12 1367-2630 53 21135621 18087432 10.1088/1367-2630/13/1/013012 1367-2630 URN:SI:UM:DK:IHZTLYNS New_Journal_of_Physics_2011_Gosak,_Korosak,_Marhl_Topologically_determined_optimal_stochastic_resonance_responses_of_spatially_embedded.pdf New_Journal_of_Physics_2011_Gosak,_Korosak,_Marhl_Topologically_determined_optimal_stochastic_resonance_responses_of_spatially_embedded.pdf 1 CD73821CE0D968112D36C457821ABC62 3dea4c555ed6f0e3cc540421f4c7a2ab0554e23ad6bd1954db4db08599e6a811 55d8359c-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/fd300731-2261-47b0-9603-26392044ad93 https://dk.um.si/Dokument.php?lang=slv&id=113464 http://stacks.iop.org/1367-2630/13/i=1/a=013012?key=crossref.5cd62d33d20126c6b370b6b9cef1a5f5 1 https://dk.um.si/Dokument.php?lang=slv&id=46242 Fakulteta za naravoslovje in matematiko 0 0 0
