Query: Mobility-enhanced signal response in metapopulation networks of coupled
  oscillators   We investigate the effect of mobility on the response of coupled oscillators
to a subthreshold external signal in metapopulation networks, wherein each node
represents a subpopulation with overdamped bistable oscillators that can
randomly diffuse between nodes. With increasing mobility rate, the oscillators
undergo transitions from intrawell to interwell motion, demonstrating clearly
mobility-enhanced signal amplification. Moreover, the response shows
nonmonotonic dependence on the mobility rate, i.e., a maximal gain occurs at a
moderate level of mobility. This interesting phenomenon is robust against
variations in the overall density, network size, as well as network topology.
In addition, a simple mean-field analysis is carried out to qualitatively
illustrate the simulation results.
