Although typically assumed to degrade performance, random fluctuations, or noise, can
sometimes improve information processing in non-linear systems. One such form …

Stochastic resonance is said to be observed when increases in levels of unpredictable
fluctuations—eg, random noise—cause an increase in a metric of the quality of signal …

Critical phenomena in complex networks, and the emergence of dynamical abrupt
transitions in the macroscopic state of the system are currently a subject of the outmost …

We study the spatial dynamics of spiral waves in noisy Hodgkin–Huxley neuronal
ensembles evoked by different information transmission delays and network topologies. In …

The effect of cellular heterogeneity on the coding properties of neural populations is studied
analytically and numerically. We find that heterogeneity decreases the threshold for …

We study the impact of additive Gaussian noise and weak periodic forcing on the dynamics
of a scale-free network of bistable overdamped oscillators. The periodic forcing is introduced …

A widely held assumption on network dynamics is that similar components are more likely to
exhibit similar behavior than dissimilar ones and that generic differences among them are …

This letter focuses on the effect of repulsive interactions on the adoption of an external
message in an opinion model. With a simple change in the rules, we modify the Deffuant et …

Background Bistability, the capacity to achieve two distinct stable steady states in response
to a set of external stimuli, arises within biological systems ranging from the λ phage switch …

Photosynthesis is a key process in plants that can be strongly affected by the actions of
environmental stressors. The stressor-induced photosynthetic responses are based on …
