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…

Nonextensivity: from low-dimensional maps to Hamiltonian systems
C. Tsallis, A. Rapisarda, V. Latora +1
We present a brief pedagogical guided tour of the most recent applications of nextensive statistical mechanics to well defined nonlinear dynamical systems, ranging from one-dimensi…
Comment on "Negative specific heat for a cluster of 147 Sodium atoms" by Schmidt et al
C. Tsallis, B. J. C. Cabral, A. Rapisarda +1
Schmidt et al (Phys Rev Lett 86, 1191 (2001)) observe and analyze a negative specific heat in Na clusters. The analysis is done within the framework of Boltzmann-Gibbs equilibrium…
Time evolution of thermodynamic entropy for conservative and dissipative chaotic maps
M. Baranger, V. Latora, A. Rapisarda
We consider several low--dimensional chaotic maps started in far-from-equilibrium initial conditions and we study the process of relaxation to equilibrium. In the case of conservat…
