Directivity of Quantum Walk via Its Random Walk Replica

open access: yesComplexity, 2022
Quantum walks (QWs) exhibit different properties compared with classical random walks (RWs), most notably by linear spreading and localization. In the meantime, random walks that replicate quantum walks, which we refer to as quantum-walk-replicating ...

Application of random walk to model temperature in 60 African cities for the 20th century [PDF]

open access: yesE3S Web of Conferences, 2021
The 20th century is marked with climate change led by global warming. So far, many models have been applied to analyze the temperature change. However, a simple but interesting model, a random walk is hardly used in his regard.

Random walk on random walks: higher dimensions [PDF]

open access: yesElectronic Journal of Probability, 2019
We study the evolution of a random walker on a conservative dynamic random environment composed of independent particles performing simple symmetric random walks, generalizing results of [16] to higher dimensions and more general transition kernels without the assumption of uniform ellipticity or nearest-neighbour jumps.

Long-Term Air Quality Study in Fairbanks, Alaska: Air Pollutant Temporal Variations, Correlations, and PM2.5 Source Apportionment

open access: yesAtmosphere, 2020
As one of the most polluted U.S. cities, Fairbanks was reclassified as a “serious” nonattainment area by the Environmental Protection Agency (EPA) in 2017 for its fine particulate matter (PM2.5) pollution.

A Semi-Deterministic Random Walk with Resetting

open access: yesEntropy, 2021
We consider a discrete-time random walk (xt) which, at random times, is reset to the starting position and performs a deterministic motion between them. We show that the quantity Prxt+1=n+1|xt=n,n→∞ determines if the system is averse, neutral or inclined

Multifractal random walk [PDF]

open access: yesPhysical Review E, 2001
We introduce a class of multifractal processes, referred to as Multifractal Random Walks (MRWs). To our knowledge, it is the first multifractal processes with continuous dilation invariance properties and stationary increments. MRWs are very attractive alternative processes to classical cascade-like multifractal models since they do not involve any ...

Conservative random walk

open access: yesElectronic Journal of Probability, 2022
Recently, in ["The coin-turning walk and its scaling limit", Electronic Journal of Probability, 25 (2020)], the ``coin-turning walk'' was introduced on ${\mathbb Z}$. It is a non-Markovian process where the steps form a (possibly) time-inhomogeneous Markov chain.

A phase transition in the random transposition random walk [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
Our work is motivated by Bourque-Pevzner's simulation study of the effectiveness of the parsimony method in studying genome rearrangement, and leads to a surprising result about the random transposition walk in continuous time on the group of ...

Random Infinite Permutations and the Cyclic Time Random Walk [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
The random stirring process is a natural random walk on the set of permutations of the vertex set of a graph. The cyclic time random walk is a self interacting random walk on a graph.

A random-walk-based epidemiological model

open access: yesScientific Reports, 2021
Random walkers on a two-dimensional square lattice are used to explore the spatio-temporal growth of an epidemic. We have found that a simple random-walk system generates non-trivial dynamics compared with traditional well-mixed models.
