Switching times in long-overlap Josephson junctions subject to thermal fluctuations and non-Gaussian noise sources [PDF]
, 2014 We investigate the superconducting lifetime of long current-biased Josephson junctions, in the presence of Gaussian and non-Gaussian noise sources. In particular, we analyze the dynamics of a Josephson junction as a function of the noise signal intensity,

Particle Spectra and Mass Composition in the Ultra-High Energy Region in the Framework of the Galactic Origin of Cosmic Rays [PDF]
, 2017 The possibility for a self-consistent description of all the basic features of the observed cosmic ray spectra and primary composition variations in the energy range of $10^{15}\div 10^{20}$ eV within the Galactic origin scenario is examined. We assume

A stochastic model of randomly accelerated walkers for human mobility
Nature Communications, 2016 Many human mobility studies have shown empirically long-tailed distance distributions, which are usually associated to Lévy flights. Here, the authors show that the behavior of private vehicles could be misinterpreted as Lévy flights but is fully ...

The evolutionary maintenance of Lévy flight foraging.
PLoS Computational Biology, 2022 Lévy flight is a type of random walk that characterizes the behaviour of many natural phenomena studied across a multiplicity of academic disciplines; within biology specifically, the behaviour of fish, birds, insects, mollusks, bacteria, plants, slime ...

Optimal search in interacting populations: Gaussian jumps versus Lévy flights [PDF]
, 2014 We investigated the relationships between search efficiency, movement strategy, and nonlocal communication in the biological context of animal foraging. We considered situations where the members of a population of foragers perform either Gaussian jumps ...

A space-fractional cable equation for the propagation of action potentials in myelinated neurons [PDF]
, 2020 Myelinated neurons are characterized by the presence of myelin, a multilaminated wrapping around the axons formed by specialized neuroglial cells. Myelin acts as an electrical insulator and therefore, in myelinated neurons, the action potentials do not ...

Mittag–Leffler Memory Kernel in Lévy Flights
Mathematics, 2019 In this article, we make a detailed study of some mathematical aspects associated with a generalized Lévy process using fractional diffusion equation with Mittag−Leffler kernel in the context of Atangana−Baleanu operator.

Adaptive Lévy walks in foraging fallow deer. [PDF]
PLoS ONE, 2009 BACKGROUND: Lévy flights are random walks, the step lengths of which come from probability distributions with heavy power-law tails, such that clusters of short steps are connected by rare long steps.

Anomalous fluctuation relations [PDF]
, 2013 We study Fluctuation Relations (FRs) for dynamics that are anomalous, in the sense that the diffusive properties strongly deviate from the ones of standard Brownian motion. We first briefly review the concept of transient work FRs for stochastic dynamics

Tight Bounds for the Cover Times of Random Walks with Heterogeneous Step Lengths [PDF]
, 2019 Search patterns of randomly oriented steps of different lengths have been observed on all scales of the biological world, ranging from the microscopic to the ecological, including in protein motors, bacteria, T-cells, honeybees, marine predators, and ...
