searcher performs symmetric Lévy flights onto the accessible area. We investigate the influence of local and non …-local information, the exponent characterizing asymptotic behavior of Lévy flights, boundary conditions, density of links and type of a … asymptotic behavior of Lévy flights. Consequently, among the whole spectrum of exponents characterizing the power law behavior of …

Kinetic-growth self-avoiding walks on small-world networks

Herrero, C. P. - In: The European Physical Journal B - Condensed Matter and … 56 (2007) 1, pp. 71-79

Kinetically-grown self-avoiding walks have been studied on Watts-Strogatz small-world networks, rewired from a two-dimensional square lattice. The maximum length L of this kind of walks is limited in regular lattices by an attrition effect, which gives finite values for its mean value 〈L 〉....

Quantitative relations between corruption and economic factors

Shao, Jia; Ivanov, Plamen Ch.; Podobnik, Boris; … - In: The European Physical Journal B - Condensed Matter and … 56 (2007) 2, pp. 157-166

We report quantitative relations between corruption level and economic factors, such as country wealth and foreign investment per capita, which are characterized by a power law spanning multiple scales of wealth and investment per capita. These relations hold for diverse countries, and also...

Power-law autocorrelated stochastic processes with long-range cross-correlations

Podobnik, B.; Fu, D. F.; Stanley, H. E.; Ivanov, P. Ch. - In: The European Physical Journal B - Condensed Matter and … 56 (2007) 1, pp. 47-52

We develop a stochastic process with two coupled variables where the absolute values of each variable exhibit long-range power-law autocorrelations and are also long-range cross-correlated. We investigate how the scaling exponents characterizing power-law autocorrelation and long-range...

A general nonlinear Fokker-Planck equation and its associated entropy

Schwämmle, V.; Curado, E. M.F.; Nobre, F. D. - In: The European Physical Journal B - Condensed Matter and … 58 (2007) 2, pp. 159-165

A recently introduced nonlinear Fokker-Planck equation, derived directly from a master equation, comes out as a very general tool to describe phenomenologically systems presenting complex behavior, like anomalous diffusion, in the presence of external forces. Such an equation is characterized by...
