Isochronous Oscillators [PDF]

open access: yesJournal of Nonlinear Mathematical Physics, 2021
The authors consider a Hamiltonian system of \(2N+2\) oscillators. They exhibit the solutions of its initial value problem. In the classical context the solutions are completely periodic for arbitrary initial data. In the quantal context the infinitely degenerate spectrum is equispaced. All the corresponding eigenfunctions are also exhibited.

Neutrino Oscillations [PDF]

open access: yesAdvances in High Energy Physics, 2014
In the last decades, a very important breakthrough has been brought about in the elementary particle physics by the discovery of the phenomenon of the neutrino oscillations, which has shown neutrino properties beyond the Standard Model. But a full understanding of the various aspects of the neutrino oscillations is far to be achieved. In this paper the

Coupled-Oscillators [PDF]

open access: yesInternational Astronomical Union Colloquium, 1993
AbstractModal coupling oscillation models for the stellar radial pulsation and coupled-oscillators are reviewed. Coupled-oscillators with the second-order and third-order terms seemed to behave non-systematically. Using the equation by Schwarzschild and Savedoff (1949) with the dissipation term of van del Pol’s type which is third-order, we demonstrate

Braided oscillators [PDF]

open access: yesJournal of Mathematical Physics, 2002
A generalized oscillator algebra is proposed and the braided Hopf algebra structure for this generalized oscillator is investigated. Using the solutions for the braided Hopf algebra structure, two types of braided Fibonacci oscillators are introduced. This leads to two types of braided Biedenharn–Macfarlane oscillators as special cases of the Fibonacci

Novel long-range inhibitory nNOS-expressing hippocampal cells

open access: yeseLife, 2019
The hippocampus, a brain region that is important for spatial navigation and episodic memory, benefits from a rich diversity of neuronal cell-types. Through the use of an intersectional genetic viral vector approach in mice, we report novel hippocampal ...

DIAMAGNETIC MODULATION OF TRANSVERSE GALVANOMAGNETIC EFFECTS IN LONGITUDINAL AUTOSOLITON IN P-INSB

open access: yesВестник Северо-Кавказского федерального университета, 2022
Experiments show that Ettingshausen effect that is revealed in longitudinal autosoliton in transverse magnetic field that causes movement in the autosoliton can be suppressed with diamagnetism, which appears in the longitudinal magnetic field. Current in

Cucker–Smale model, time-varying topological structures, time delay, flocking, persistence of excitation

open access: yesMathematical Modelling and Control, 2022
In this paper, we consider a class of fractional partial differential equations with damping term subject to Robin and Dirichlet boundary value conditions.

Neutrino oscillations [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2013
This review summarizes recent experimental and theoretical progress in determining neutrino mixing angles and masses through neutrino oscillations. We describe the basic physics of oscillation phenomena in vacuum and matter, as well as the status of solar, reactor, atmospheric, and accelerator neutrino experiments that probe these phenomena.
