Intermittent pathways towards a dynamical target
Félix Rojo, Pedro A. Pury, Carlos E. Budde
In this paper, we investigate the quest for a single target, that remains fixed in a lattice, by a set of independent walkers. The target exhibits a fluctuating behavior between tr…
Lifetime of a target in the presence of N independent walkers
Félix Rojo, Pedro A. Pury, Carlos E. Budde
We study the survival probability of an immobile target in presence of N independent diffusing walkers. We address the problem of the Mean Target Lifetime and its dependence on the…
Multifractal spectra of mean first-passage time distributions in disordered chains
Pedro A. Pury, Manuel O. Caceres
The multifractal characterization of the distribution over disorder of the mean first-passage time in a finite chain is revisited. Both, absorbing-absorbing and reflecting-absorbin…
Mean first-passage and residence times of random walks on asymmetric disordered chains
Pedro A. Pury, Manuel O. Caceres
An algebraic derivation is presented which yields the exact solution of the mean first-passage and mean residence times of a one-dimensional asymmetric random walk for quenched dis…
Survival and residence times in disordered chains with bias
Pedro A. Pury, Manuel O. Caceres
We present a unified framework for first-passage time and residence time of random walks in finite one-dimensional disordered biased systems. The derivation is based on exact expan…
Long-range fractal correlations in literary corpora
Marcelo A. Montemurro, Pedro A. Pury
In this paper we analyse the fractal structure of long human-language records by mapping large samples of texts onto time series. The particular mapping set up in this work is insp…
