Detecting unknown paths on complex networks through random walks

Wang, Shao-Ping; Pei, Wen-Jiang - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 4, pp. 514-522

In this article, we investigate the problem of detecting unknown paths on complex networks through random walks. To detect a given path on a network a random walker should pass through the path from its initial node to its terminal node in turn. We calculate probability ϕ(t) that a random...

Pair formation within multi-agent populations

Smith, David M.D.; Johnson, Neil F. - In: Physica A: Statistical Mechanics and its Applications 363 (2006) 1, pp. 151-158

We present a simple model for the formation of pairs in multi-agent populations of type A and B which move freely on a spatial network. Each agent of population A (and B) is labeled as Ai (and Bj) with i=1,...,NA (and j=1,...,NB) and carries its own individual list of characteristics or...

A power-law distribution for tenure lengths of sports managers

Aidt, Toke S.; Leong, Bernard; Saslaw, William C.; … - In: Physica A: Statistical Mechanics and its Applications 370 (2006) 2, pp. 697-703

We show that the tenure lengths for managers of sport teams follow a power law distribution with an exponent between 2 and 3. We develop a simple theoretical model which replicates this result. The model demonstrates that the empirical phenomenon can be understood as the macroscopic outcome of...

Pattern synchrony in electrical signals related to earthquake activity

Hernández-Pérez, R.; Guzmán-Vargas, L.; … - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 6, pp. 1239-1252

We apply the cross sample entropy method to geoelectrical time series collected from independent channels (North–South and East–West directions) monitored at two sites located in Mexico, to assess the presence of pattern synchrony between the signals, particularly in the proximity of...
