Distribution of return intervals of extreme events

Pennetta, C. - In: The European Physical Journal B - Condensed Matter and … 50 (2006) 1, pp. 95-98

The distribution of return intervals of extreme events is studied in time series characterized by finite-term correlations with non-exponential decay. Precisely, it has been analyzed the statistics of the return intervals of extreme values of the resistance fluctuations displayed by resistors...

Frequency and phase synchronization of two coupled neurons with channel noise

Yu, L. C.; Chen, Y.; Zhang, Pan - In: The European Physical Journal B - Condensed Matter and … 59 (2007) 2, pp. 249-257

We study the frequency and phase synchronization in two coupled identical and nonidentical neurons with channel noise … strength of channel noise is represented by ion channel cluster size of neurons. It is shown that channel noise allows the two … and channel noise. Those regimes are characterized by the distribution of the cyclic relative phase corresponding to …

Study of the non-linear autocorrelations within the Gaussian regime

Kutner, R.; Świtała, F. - In: The European Physical Journal B - Condensed Matter and … 33 (2003) 4, pp. 495-503

In this work we extend the recently considered toy model of Weierstrass or Lévy walks with varying velocity of the walker [1] by introducing a more realistic possibility that the walk can be occasionally intermitted by its momentary localization; the localizations themselves are again described...

Inefficiency in Latin-American market indices

Zunino, L.; Tabak, B. M.; Pérez, D. G.; Garavaglia, M.; … - In: The European Physical Journal B - Condensed Matter and … 60 (2007) 1, pp. 111-121

We explore the deviations from efficiency in the returns and volatility returns of Latin-American market indices. Two different approaches are considered. The dynamics of the Hurst exponent is obtained via a wavelet rolling sample approach, quantifying the degree of long memory exhibited by the...

Statistical equilibrium in simple exchange games II. The redistribution game

Garibaldi, U.; Scalas, E.; Viarengo, P. - In: The European Physical Journal B - Condensed Matter and … 60 (2007) 2, pp. 241-246

We propose a simple stochastic exchange game mimicking taxation and redistribution. There are g agents and n coins; taxation is modeled by randomly extracting some coins; then, these coins are redistributed to agents following Polya's scheme. The individual wealth equilibrium distribution for...
