Diffusion with stochastic resetting.
We study simple diffusion where a particle stochastically resets to its initial position at a constant rate r. A finite resetting rate leads to a nonequilibrium stationary state with non-Gaussian fluctuations for the particle position. We also show that the mean time to find a stationary target by a diffusive searcher is finite and has a minimum value at an optimal resetting rate r*. Resetting ...
متن کاملEffect of partial absorption on diffusion with resetting.
The effect of partial absorption on a diffusive particle which stochastically resets its position with a finite rate r is considered. The particle is absorbed by a target at the origin with absorption "velocity" a; as the velocity a approaches ∞ the absorption property of the target approaches that of a perfectly absorbing target. The effect of partial absorption on first-passage time problems ...
متن کاملOptimal first-arrival times in Lévy flights with resetting.
We consider the diffusive motion of a particle performing a random walk with Lévy distributed jump lengths and subject to a resetting mechanism, bringing the walker to an initial position at uniformly distributed times. In the limit of an infinite number of steps and for long times, the process converges to superdiffusive motion with replenishment. We derive a formula for the mean first arrival...
متن کاملType-II phase resetting curve is optimal for stochastic synchrony.
The phase-resetting curve (PRC) describes the response of a neural oscillator to small perturbations in membrane potential. Its usefulness for predicting the dynamics of weakly coupled deterministic networks has been well characterized. However, the inputs to real neurons may often be more accurately described as barrages of synaptic noise. Effective connectivity between cells may thus arise in...
متن کاملOptimal Evaluation Clocking of Self-Resetting Domino Pipelines
We describe a high performance clocking methodology for domino pipelines. Our technique maximizes the clock rate of the circular pipeline (“ring”) while maintaining the ring cycle time to be the worst-case combinational logic delay around the ring. It is relatively immune to global clock skew, incurs no latch overhead, allows up to 50% time borrowing, and offers a robust way of preventing race-...
