Lengths and heights of random walk excursions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 Consider a simple symmetric random walk on the line. The parts of the random walk between consecutive returns to the origin are called excursions. The heights and lengths of these excursions can be arranged in decreasing order.

Experimental Implementation of the Quantum Random-Walk Algorithm
, 2003 The quantum random walk is a possible approach to construct new quantum algorithms. Several groups have investigated the quantum random walk and experimental schemes were proposed.

Late Points and Cover Times of Projections of Planar Symmetric Random Walks on the Lattice Torus [PDF]
, 2014 We examine the sets of late points of a symmetric random walk on $Z^2$ projected onto the torus $Z^2_K$, culminating in a limit theorem for the cover time of the toral random walk.

Persistent random walk with exclusion
, 2013 Modelling the propagation of a pulse in a dense {\em milieu} poses fundamental challenges at the theoretical and applied levels. To this aim, in this paper we generalize the telegraph equation to non-ideal conditions by extending the concept of ...

A Random Walk to Economic Freedom? [PDF]
The European Journal of Comparative Economics, 2013 Given the wide use of economic freedom in economic literature it is imperative to understand how economic freedom evolves. Results suggest that levels of economic freedom are dominated by random shocks. Using a test for stationarity devised by Westerlund

Recurrence of random walk traces
, 2005 We show that the edges crossed by a random walk in a network form a recurrent graph a.s. In fact, the same is true when those edges are weighted by the number of crossings.Comment: Published at http://dx.doi.org/10.1214/009117906000000935 in the Annals

Tunable Persistent Random Walk in Swimming Droplets
Physical Review X, 2020 We characterize the motility of athermal swimming droplets within the framework of a persistent random walk. Just like active colloids, their trajectories can be modeled with a constant velocity V and a slow angular diffusion, but the random changes in ...

A New Random Walk for Replica Detection in WSNs. [PDF]
PLoS ONE, 2016 Wireless Sensor Networks (WSNs) are vulnerable to Node Replication attacks or Clone attacks. Among all the existing clone detection protocols in WSNs, RAWL shows the most promising results by employing Simple Random Walk (SRW).
