Balancing the competing demands of harvesting and safety from predation: Lévy walk searches outperform composite Brownian walk searches but only when foraging under the risk of pre...

Reynolds, A.M. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 21, pp. 4740-4746

Some foragers have movement patterns that can be approximated by Lévy walks whilst others may be better represented as composite Brownian walks. Many attempts have been made to interpret these movement patterns in terms of optimal searching strategies for the location of randomly and sparsely...

On synchronizability and heterogeneity in unweighted networks

Hao, Binbin; Yu, Hao; Jing, Yuanwei; Zhang, Siying - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 9, pp. 1939-1945

density and heterogeneity in degree distribution. In this work, it will be shown that synchronizability of Type I networks is … independent of heterogeneity in the degree distribution when the link density is smaller than 0.02. Synchronizability and link … density are proportional. When the link density is larger than 0.025, heterogeneity decides the curve slope. The …
