Here, collective excitability and self-sustained bursting oscillations are shown to spontaneously emerge in globally coupled popula...

]]>The noise-driven motion in a bistable potential acts as the archetypal model of various physical phenomena. Here, we contrast properties of the overdamped escape dynamics with the full (underdamped) dynamics. In the weak noise limit, for the overdamped particle driven by nonequilibrium, $\alpha $-stable noi...

Our approach builds on past work where the graph-based approach was successfully used to simulate steady-state fluid flows in fractured media. We find a mean computational speedup of th...

However, a solid mathematical t...
