Aging Induced Multifractality
P. Allegrini, J. Bellazzini, G. Bramanti +3
We show that the dynamic approach to Lévy statistics is characterized by aging and multifractality, induced by an ultra-slow transition to anomalous scaling. We argue that these as…
Facing Non-Stationary Conditions with a New Indicator of Entropy Increase: The Cassandra Algorithm
P. Allegrini, P. Grigolini, P. Hamilton +3
We address the problem of detecting non-stationary effects in time series (in particular fractal time series) by means of the Diffusion Entropy Method (DEM). This means that the ex…
Memory beyond memory in heart beating: an efficient way to detect pathological conditions
P. Allegrini, P. Grigolini, P. Hamilton +2
We study the long-range correlations of heartbeat fluctuations with the method of diffusion entropy. We show that this method of analysis yields a scaling parameter that appare…
