Directed Cascades Generate New Critical Universality Classes
Didier Sornette, Eugenio Lippiello, Giuseppe Petrillo
Spectrally stable cascades can undergo enormous transient growth before eventually dying out. We show that this amplification is controlled by the directed architecture of the inte…
Janus Percolation in Anisotropic Limited-Degree Networks
Jacopo A. Garofalo, Nuno A. M. Araújo, Lucilla de Arcangelis +2
Many real-world infrastructures, from sensor and road networks to power grids, are spatially embedded and anisotropic, with constraints on the maximum number of links each node can…
Anomalous Critical Behavior of Driven Disordered Systems Beyond the Overdamped Limit
Giuseppe Petrillo, Eduardo Jagla, Eugenio Lippiello +1
We investigate the role of relaxation mechanisms in the driven response of elastic disordered interfaces in finite dimensions, focusing on the interplay between dimensionality and…
Improve the estimate of the b-value in regional catalogs by means of the the b-more positive method
Eugenio Lippiello, Cataldo Godano, Giuseppe Petrillo
The b-value, which controls the slope of the frequency-magnitude distribution of earthquakes, is a critical parameter in seismic forecasting. However, accurately measuring the true…
