Stochastic Wilson–Cowan models of neuronal network dynamics with memory and delay

open access: yesNew Journal of Physics, 2015
We consider a simple Markovian class of the stochastic Wilson–Cowan type models of neuronal network dynamics, which incorporates stochastic delay caused by the existence of a refractory period of neurons.

Level 2 and level 2.5 large deviation functionals for systems with and without detailed balance

open access: yesNew Journal of Physics, 2016
Large deviation functions are an essential tool in the statistics of rare events. Often they can be obtained by contraction from a so-called level 2 or level 2.5 large deviation functional characterizing the empirical density and current of the ...

Mesoscopic virial equation for nonequilibrium statistical mechanics

open access: yesNew Journal of Physics, 2016
We derive a class of mesoscopic virial equations governing energy partition between conjugate position and momentum variables of individual degrees of freedom.

Forecasting the magnitude and onset of El Niño based on climate network

open access: yesNew Journal of Physics, 2018
El Niño is probably the most influential climate phenomenon on inter-annual time scales. It affects the global climate system and is associated with natural disasters; it has serious consequences in many aspects of human life. However, the forecasting of

Effects of the target aspect ratio and intrinsic reactivity onto diffusive search in bounded domains

open access: yesNew Journal of Physics, 2017
We study the mean first passage time (MFPT) to a reaction event on a specific site in a cylindrical geometry—characteristic, for instance, for bacterial cells, with a concentric inner cylinder representing the nuclear region of the bacterial cell.

Comment on "Mean First Passage Time for Anomalous Diffusion"

open access: yes, 2004
We correct a previously erroneous calculation [Phys. Rev. E 62, 6065 (2000)] of the mean first passage time of a subdiffusive process to reach either end of a finite interval in one dimension.

A stochastic approach for quantifying immigrant integration: the Spanish test case

open access: yesNew Journal of Physics, 2014
We apply stochastic process theory to the analysis of immigrant integration. Using a unique and detailed data set from Spain, we study the relationship between local immigrant density and two social and two economic immigration quantifiers for the period

New Polynomials and Numbers Associated with Fractional Poisson Probability Distribution

open access: yes, 2010
Generalizations of Bell polynomials, Bell numbers, and Stirling numbers of the second kind have been introduced and their generating functions were evaluated.Comment: ICNAAM 2010: International Conference of Numerical Analysis and Applied Mathematics ...

1/f noise for intermittent quantum dots exhibits non-stationarity and critical exponents

open access: yesNew Journal of Physics, 2014
The power spectrum of quantum dot (QD) fluorescence exhibits $1/{{f}^{\beta }}$ noise, related to the intermittency of these nanosystems. As in other systems exhibiting $1/f$ noise, this power spectrum is not integrable at low frequencies, which appears ...
