New Journal of Physics, 2020 We consider the emerging dynamics of a separable continuous time random walk (CTRW) in the case when the random walker is biased by a velocity field in a uniformly growing domain.

On the Advent of Fractional Calculus in Econophysics via Continuous-Time Random Walk
Mathematics, 2020 In this survey article, at first, the author describes how he was involved in the late 1990s on Econophysics, considered in those times an emerging science.

Frontiers in Water, 2021 Hydrodynamic dispersion process in relation with the geometrical properties of the porous media are studied in two sets of 6 porous media samples of porosity θ ranging from 0.1 to 0.25. These two sets of samples display distinctly different evolutions of

SOLUTE TRANSPORT MODELLING IN LOW-PERMEABILITY HOMOGENEOUS AND SATURATED SOIL MEDIA
Rudarsko-geološko-naftni Zbornik, 2021 Fickian and non-Fickian behaviors were often detected for contaminant transport activity owed to the preferential flow and heterogeneity of soil media. Therefore, using diverse methods to measure such composite solute transport in soil media has become ...

On the relationship between continuous- and discrete-time quantum walk [PDF]
, 2008 Quantum walk is one of the main tools for quantum algorithms. Defined by analogy to classical random walk, a quantum walk is a time-homogeneous quantum process on a graph. Both random and quantum walks can be defined either in continuous or discrete time.

Cluster continuous time random walks [PDF]
Studia Mathematica, 2011 In a continuous time random walk (CTRW), a random waiting time pre- cedes each random jump. The CTRW model is useful in physics, to model diusing par- ticles. Its scaling limit is a time-changed process, whose densities solve an anomalous diusion equation.

Patient treatment prediction by continuous time random walk inside complex system
MATEC Web of Conferences, 2018 Stochastic resonance model for medical patient condition is proposed. Approach has been generalized by means of fractional Fokker-Planck equation and subdiffusion processes.

Correlated continuous time random walks [PDF]
Statistics & Probability Letters, 2009 Continuous time random walks impose a random waiting time before each particle jump. Scaling limits of heavy tailed continuous time random walks are governed by fractional evolution equations. Space-fractional derivatives describe heavy tailed jumps, and the time-fractional version codes heavy tailed waiting times.

Chover-Type Laws of the Iterated Logarithm for Continuous Time Random Walks
Journal of Applied Mathematics, 2012 A continuous time random walk is a random walk subordinated to a renewal process used in physics to model anomalous diffusion. In this paper, we establish Chover-type laws of the iterated logarithm for continuous time random walks with jumps and waiting ...
