Discrete structure of the brain rhythms
Luca Perotti, Justin DeVito, Daniel Bessis +1
Neuronal activity in the brain generates synchronous oscillations of the Local Field Potential (LFP). The traditional analyses of the LFPs are based on decomposing the signal into…
Motion of a superconducting loop in an inhomogeneous magnetic field: a didactic experiment
Marco Giliberti, Luca Perotti, Lucio Rossi
We present an experiment conductive to an understanding of both Faraday's law and the properties of the superconducting state. It consists in the analysis of the motion of a superc…
Matrix methods for Padé approximation: numerical calculation of poles, zeros and residues
Luca Perotti, Michal Wojtylak
A representation of the Padé approximation of the -transform of a signal as a resolvent of a tridiagonal matrix is given. Several formulas for the poles, zeros and residues…
Recovery of the starting times of delayed signals
Luca Perotti, Daniel Vrinceanu, Daniel Bessis
We present a new method to locate the starting points in time of an arbitrary number of (damped) delayed signals. For a finite data sequence, the method permits to first locate the…
Extreme value laws for fractal intensity functions in dynamical systems: Minkowski analysis
Giorgio Mantica, Luca Perotti
Typically, in the dynamical theory of extremal events, the function that gauges the intensity of a phenomenon is assumed to be convex and maximal, or singular, at a single, or at m…
Truncations of a class of pseudo-Hermitian operators
Maxim Derevyagin, Luca Perotti, Michal Wojtylak
We consider the class of non-Hermitian operators represented by infinite tridiagonal matrices, selfadjoint in an indefinite inner product space with one negative square. We approxi…
