In the search for the low-complexity sequences in prokaryotic and eukaryotic genomes: how to derive a coherent picture from global and local entropy measures
Claudia Acquisti, Paolo Allegrini, Patrizia Bogani +6
We investigate on a possible way to connect the presence of Low-Complexity Sequences (LCS) in DNA genomes and the nonstationary properties of base correlations. Under the hypothesi…
Detection of invisible and crucial events: from seismic fluctuations to the war against terrorism
Paolo Allegrini, Leone Fronzoni, Paolo Grigolini +5
We prove the efficiency of a new method for the detection of crucial events that might have useful applications to the war against terrorism. This has to do with the search for rar…

Conflict between trajectories and density description: the statistical source of disagreement
Paolo Allegrini, Paolo Grigolini, Luigi Palatella +1
We study an idealized version of intermittent process leading the fluctuations of a stochastic dichotomous variable . It consists of an overdamped and symmetric potential well w…
Asymmetric Anomalous Diffusion: an Efficient Way to Detect Memory in Time Series
Paolo Grigolini, Luigi Palatella, Giacomo Raffaelli
We study time series concerning rare events. The occurrence of a rare event is depicted as a jump of constant intensity always occurring in the same direction, thereby generating a…
Macroscopic Manifestation of Microscopic Entropy Production: Space-Dependent Intermittence
Paolo Grigolini, Riccardo Mannella, Luigi Palatella
We study a spatial diffusion process generated by velocity fluctuations of intermittent nature. We note that intermittence reduces the entropy production rate while enhancing the d…
