This new phenomenon is a direct consequence of the existence of a scaling law for the signal-to-noise ratio and implies the appearance of stochastic resonance in some monostable systems. We outline applications of our results to a wide variety of systems pertaining to different scientific areas. Two particular examples are discussed in detail.4 p.application/pdfeng(c) American Physical Society, 1996TermodinàmicaMecànica estadísticaThermodynamicsStatistical mechanicsinfo:eu-repo/semantics/article117510info:eu-repo/semantics/openAccess
