Synchronization in weighed scale-free networks with degree-degree correlation
F. Sorrentino, M. di Bernardo, G. Huerta Cuellar +1
We study synchronization phenomena in scale-free networks of asymetrically coupled dynamical systems featuring degree-degree correlation in the connection wiring. We show that when…
Double coherence resonance in neuron models driven by discrete correlated noise
Thomas Kreuz, Stefano Luccioli, Alessandro Torcini
We study the influence of correlations among discrete stochastic excitatory or inhibitory inputs on the response of the FitzHugh-Nagumo neuron model. For any level of correlation t…
Identification of network modules by optimization of ratio association
Leonardo Angelini, Stefano Boccaletti, Daniele Marinazzo +2
We introduce a novel method for identifying the modular structures of a network based on the maximization of an objective function: the ratio association. This cost function arises…
Coherent response of the Hodgkin-Huxley neuron in the high-input regime
Alessandro Torcini, Stefano Luccioli, Thomas Kreuz
We analyze the response of the Hodgkin-Huxley neuron to a large number of uncorrelated stochastic inhibitory and excitatory post-synaptic spike trains. In order to clarify the vari…
Desynchronized stable states in diluted neural networks
Ruediger Zillmer, Roberto Livi, Antonio Politi +1
The dynamical properties of a diluted fully-inhibitory network of pulse-coupled neurons are investigated. Depending on the coupling strength, two different phases can be observed.…
Mosaic multi-state scenario vs. one-state description of supercooled liquids
Andrea Cavagna, Tomas S. Grigera, Paolo Verrocchio
According to the mosaic scenario, relaxation in supercooled liquids is ruled by two competing mechanisms: surface tension, opposing the creation of local excitations, and entropy,…
