Drastic disorder-induced reduction of signal amplification in scale-free networks 2015 Access copy available to the general public Unrestricted Understanding information transmission across a network is a fundamental task for controlling and manipulating both biological and manmade information-processing systems. Here we show how topological resonant-like amplification effects in scale-free networks of signaling devices are drastically reduced when phase disorder in the external signals is considered. This is demonstrated theoretically by means of a starlike network of overdamped bistable systems, and confirmed numerically by simulations of scale-free networks of such systems. The taming effect of the phase disorder is found to be sensitive to the amplification’s strength, while the topology-induced amplification mechanism is robust against this kind of quenched disorder in the sense that it does not significantly change the values of the coupling strength where amplification is maximum in its absence. info:eu-repo/grantAgreement/ES/MINECO/FIS2011-25167 info:eu-repo/grantAgreement/ES/MINECO/FIS2012-34902 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.252 2015 PHYSICS, MATHEMATICAL 6 / 53 = 0.113 2015 Q1 T1 PHYSICS, FLUIDS & PLASMAS 10 / 30 = 0.333 2015 Q2 T2 1.183 2015 Condensed Matter Physics 2015 Q1 Statistical and Nonlinear Physics 2015 Q1 Statistics and Probability 2015 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-1625-2785 Martínez, P.J.
