First passage time properties of diffusion with a broad class of stochastic diffusion coefficients
Go Uchida, Hiromi Miyoshi, Hitoshi Washizu
This study investigates the first passage time (FPT) properties of particles with a broad class of positive stochastic diffusion coefficients (DCs), representing diffusion in heter…

Coherence resonance for time-averaged measures
Go Uchida
Noise can induce time order in the dynamics of nonlinear dynamical systems. For example, coherence resonance occurs in various neuron models driven by a noise. In studies of cohere…

Diffusion with a broad class of stochastic diffusion coefficients
Go Uchida, Hitoshi Washizu, Hiromi Miyoshi
In many physical or biological systems, diffusion can be described by Brownian motions with stochastic diffusion coefficients (DCs). In the present study, we investigate properties…
