Subordination Pathways to Fractional Diffusion

, 2011
The uncoupled Continuous Time Random Walk (CTRW) in one space-dimension and under power law regime is splitted into three distinct random walks: (rw_1), a random walk along the line of natural time, happening in operational time; (rw_2), a random walk ...

HESS Opinions "A random walk on water" [PDF]

Hydrology and Earth System Sciences, 2010
According to the traditional notion of randomness and uncertainty, natural phenomena are separated into two mutually exclusive components, random (or stochastic) and deterministic.

Incorporating Vector Space Similarity in Random Walk Inference over Knowledge Bases

Conference on Empirical Methods in Natural Language Processing, 2014
Much work in recent years has gone into the construction of large knowledge bases (KBs), such as Freebase, DBPedia, NELL, and YAGO. While these KBs are very large, they are still very incomplete, necessitating the use of inference to fill in gaps.

Doubly stochastic continuous time random walk

Physical Review Research
Since its introduction some 60 years ago, the Montroll-Weiss continuous time random walk has found numerous applications due its ease of use and ability to describe both regular and anomalous diffusion. Yet, despite its broad applicability and generality,

The Global Mean First-Passage Time for Degree-Dependent Random Walks in a Class of Fractal Scale-Free Trees

Fractal and Fractional
Fractal scale-free structures are widely observed across a range of natural and synthetic systems, such as biological networks, internet architectures, and social networks, providing broad applications in the management of complex systems and the ...

Random Walk on T-Fractal with Stochastic Resetting

Entropy
In this study, we explore the impact of stochastic resetting on the dynamics of random walks on a T-fractal network. By employing the generating function technique, we establish a recursive relation between the generating function of the first passage ...

A note on random walk in random scenery

, 2005
We consider a d-dimensional random walk in random scenery X(n), where the scenery consists of i.i.d. with exponential moments but a tail decay of the form exp(-c t^a) with any}.

Fitts Law as a Restrained Random Walk

Comptes Rendus. Mécanique
Fitts law, one of the rare quantitative relations in psychology, describes the time it takes for a human being to aim at and hit a target of a given size, starting from a given remote position.

Estimates of random walk exit probabilities and application to loop-erased random walk

, 2005
We prove an estimate for the probability that a simple random walk in a simply connected subset A of Z^2 starting on the boundary exits A at another specified boundary point. The estimates are uniform over all domains of a given inradius.

Non-Uniformly Multidimensional Moran Random Walk with Resets

Axioms
In this paper, we investigate the non-uniform m-dimensional Moran walk (Zn(1),…,Zn(m)), where each component process (Zn(j))1≤j≤m, either increases by one unit or resets to zero at each step.
