Superconducting-insulator transition in disordered Josephson junctions networks
Linda Ponta, Valentina Andreoli, Anna Carbone
The superconducting-insulator transition is simulated in disordered networks of Josephson junctions with thermally activated Arrhenius-like resistive shunt. By solving the conducta…
Analysis of Metal Cutting Acoustic Emissions by Time Series Models
F. Polito, A. Petri, G. Pontuale +1
We analyse some acoustic emission time series obtained from a lathe machining process. Considering the dynamic evolution of the process we apply two classes of well known stationar…
Generalized synchronization in mutually coupled oscillators and complex networks
Olga Moskalenko, Alexey Koronovskii, Alexander Hramov +1
We introduce a novel concept of generalized synchronization, able to encompass the setting of collective synchronized behavior for mutually coupled systems and networking systems f…
Starling flock networks manage uncertainty in consensus at low cost
George Forrest Young, Luca Scardovi, Andrea Cavagna +2
Flocks of starlings exhibit a remarkable ability to maintain cohesion as a group in highly uncertain environments and with limited, noisy information. Recent work demonstrated that…
Symmetry breaking and restoring wave transmission in diode-antidiode double chains
Stefano Lepri, Boris A. Malomed
We introduce a system of two parallel-coupled discrete nonlinear Schroedinger (DNLS) inhomogeneous chains. Each one favors the unidirectional transmission of incident packets, in t…
A fluctuation relation for weakly ergodic aging systems
A. Crisanti, M. Picco, F. Ritort
A fluctuation relation for aging systems is introduced, and verified by extensive numerical simulations. It is based on the hypothesis of partial equilibration over phase space reg…
