Cognitive scale-free networks as a model for intermittency in human natural language
Paolo Allegrini, Paolo Grigolini, Luigi Palatella
We model certain features of human language complexity by means of advanced concepts borrowed from statistical mechanics. Using a time series approach, the diffusion entropy method…
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…
Intermittency and scale-free networks: a dynamical model for human language complexity
Paolo Allegrini, Paolo Grigolini, Luigi Palatella
In this paper we try to model certain features of human language complexity by means of advanced concepts borrowed from statistical mechanics. We use a time series approach, the di…
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…
From Knowledge, Knowability and the Search for Objective Randomness to a New Vision of Complexity
Paolo Allegrini, Martina Giuntoli, Paolo Grigolini +1
Herein we consider various concepts of entropy as measures of the complexity of phenomena and in so doing encounter a fundamental problem in physics that affects how we understand…

Breakdown of the Onsager principle as a sign of aging
Paolo Allegrini, Gerardo Aquino, Paolo Grigolini +2
We discuss the problem of the equivalence between Continuous Time Random Walk (CTRW) and Generalized Master Equation (GME). The walker, making instantaneous jumps from one site of…
Scaling in Non-stationary Time Series II: Teen Birth Phenomenon
M. Ignaccolo, P. Allegrini, P. Grigolini +2
This paper is devoted to the problem of statistical mechanics raised by the analysis of an issue of sociological interest: the teen birth phenomenon. It is expected that these data…
Scaling in Non-stationary time series I
M. Ignaccolo, P. Allegrini, P. Grigolini +2
Most data processing techniques, applied to biomedical and sociological time series, are only valid for random fluctuations that are stationary in time. Unfortunately, these data a…
