, 2015 Consider a one dimensional simple random walk X=(Xn)n≥0. We form a new simple symmetric random walk Y=(Yn)n≥0 by taking sums of products of the increments of X and study the two-dimensional walk (X,Y)=((Xn,Yn))n≥0.

Random Walks on Barycentric Subdivisions and the Strichartz Hexacarpet [PDF]
Experimental Mathematics, 2011 We investigate simple random walks on graphs generated by repeated barycentric subdivisions of a triangle. We use these random walks to study the diffusion on the self-similar fractal known as the Strichartz hexacarpet, which is generated as the limit ...

Generalized continuous-time random walks, subordination by hitting times, and fractional dynamics [PDF]
, 2009 Functional limit theorems for continuous-time random walks (CTRW) are found in the general case of dependent waiting times and jump sizes that are also position dependent.

Quenched invariance principles for random walks and elliptic diffusions in random media with boundary [PDF]
, 2014 Via a Dirichlet form extension theorem and making full use of two-sided heat kernel estimates, we establish quenched invariance principles for random walks in random environments with a boundary.

On the pertinence to Physics of random walks induced by random dynamical systems: a survey
, 2016 Let be an abstract space and a denumerable (finite or infinite) alphabet. Suppose that is a family of functions such that for all we have and a family of transformations . The pair ((Sa)a, (pa)a) is termed an iterated function system with place dependent

Mussels realize Weierstrassian Levy walks as composite correlated random walks [PDF]
, 2014 Composite correlated random walks (CCRW) have been posited as a potential replacement for Levy walks and it has also been suggested that CCRWs have been mistaken for Levy walks.

Movements of molecular motors: Ratchets, random walks and traffic phenomena [PDF]
, 2005 Processive molecular motors which drive the traffic of organelles in cells move in a directed way along cytoskeletal filaments. On large time scales, they perform motor walks, i.e., peculiar random walks which arise from the repeated unbinding from and ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
