Detecting non-linearities in data sets. Characterization of Fourier phase maps using the Weighted Scaling Indices
Roberto A. Monetti, Wolfram Bunk, Ferdinand Jamitzky +2
We present a methodology for detecting non-linearities in data sets based on the characterization of the structural features of the Fourier phase maps. A Fourier phase map is a 2D…

First-order phase transitions in non-equilibrium systems: New perspectives
Roberto A. Monetti, Alejandro Rozenfeld, Ezequiel V. Albano
First-order irreversible phase transitions (IPT's) between an active regime and an absorbing state are studied in two models by means of both simulations and mean-field stability a…
