Langevin Equations, Fokker–Planck Equations and Entropic Analysis of a Model-Independent Classical Plasma

open access: yesReports in Advances of Physical Sciences, 2021
Plasma dynamics have been studied extensively and there is a fair amount of understanding where the scientific community has reached at. However, there is still a very big gap in completely explaining plasma physics at the classical as well as the ...

Symbolic Computation Applied to Cauchy Type Singular Integrals

open access: yesMathematical and Computational Applications, 2021
The development of operator theory is stimulated by the need to solve problems emerging from several fields in mathematics and physics. At the present time, this theory has wide applications in the study of non-linear differential equations, in linear ...

Patterning of SiO2 interfaces for radiative cooling applications [PDF]

open access: yesEPJ Web of Conferences, 2023
Silicon dioxide (SiO2) is a prominent material for radiative cooling applications due to its negligible absorption at solar wavelengths (0.25-2.5 µm) and exceptional stability.

Limit cycles created by piecewise linear centers [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2019
In the last few years, the interest for studying the piecewise linear differential systems has increased strongly, mainly due to their applications to many physical phenomena. In the study of these differential systems, the limit cycles play a main role.

Quantum Entropies and Decoherence for the Multiparticle Quantum Arnol’d Cat

open access: yesEntropy, 2023
I study the scaling behavior in the physical parameters of dynamical entropies, classical and quantum, in a specifically devised model of collision-induced decoherence in a chaotic system.

Fast Optical Investigation of Cardiac Electrophysiology by Parallel Detection in Multiwell Plates

open access: yesFrontiers in Physiology, 2021
Current techniques for fast characterization of cardiac electrophysiology employ optical technologies to control and monitor action potential features of single cells or cellular monolayers placed in multiwell plates.

Linear type global centers of linear systems with cubic homogeneous nonlinearities [PDF]

open access: yesRendiconti del Circolo Matematico di Palermo Series 2, 2019
A center p of a differential system in R2 is global if R2\ { p} is filled of periodic orbits. It is known that a polynomial differential system of degree 2 has no global centers. Here we characterize the global centers of the differential systems x˙=ax+by+P3(x,y),y˙=cx+dy+Q3(x,y),with P3 and Q3 homogeneous polynomials of degree 3, and such that the ...

Curled-Skewed Wakes behind Yawed Wind Turbines Subject to Veered Inflow

open access: yesEnergies, 2022
This work presents a new engineering analytical model that predicts the effect of both the turbine yaw misalignment and the inflow wind veer on the wake flow distribution downwind of a wind turbine.
