Neutrino oscillations in Kerr-Newman space-time
, 2010 The mass neutrino oscillation in Kerr-Newman(K-N) space-time is studied in the plane $\theta=\theta_{0}$, and the general equations of oscillation phases are given. The effect of the rotation and electric charge on the phase is presented.

Control of Oscillation Patterns in a Symmetric Coupled Biological Oscillator System [PDF]
, 2003 A chain of three-oscillator system was constructed with living biological oscillators of phasmodial slime mold, Physarum polycehalum and the oscillation patterns were analyzed by the symmetric Hopf bifurcation theory using group theory.

Oscillation criteria for second order nonlinear neutral differential equations of mixed type
Electronic Journal of Qualitative Theory of Differential Equations, 2012 Some oscillation criteria are established for the second order nonlinear neutral differential equations of the form \begin{equation*} \left( \left( x(t)+a x(t-\tau_1)-b x(t+\tau_2)\right)^\alpha\right)''=q(t) x^\beta (t-\sigma_1)+p(t)x^\beta(t+\sigma_2)

A numerical study of an inline oscillating cylinder in a free stream [PDF]
, 2011 Simulations of a cylinder undergoing externally controlled sinusoidal oscillations in the free stream direction have been performed. The frequency of oscillation was kept equal to the vortex shedding frequency from a fixed cylinder, while the amplitude ...

Advances 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

Comparison theorem for oscillation of fourth-order nonlinear retarded dynamic equations
Electronic Journal of Qualitative Theory of Differential Equations, 2013 This work is concerned with oscillation of a class of fourth-order nonlinear delay dynamic equations on a time scale. A new comparison theorem is established that improves related results reported in the literature.

Journal of Neural Engineering, 2015 Oscillations are an important aspect of brain activity, but they often have a low signal-to-noise ratio (SNR) due to source-to-electrode mixing with competing brain activity and noise. Filtering can improve the SNR of narrowband signals, but it introduces ringing effects that may masquerade as genuine oscillations, leading to uncertainty as to the true

The Heisenberg oscillator [PDF]
Bulletin of Mathematical Sciences, 2012 In this short note, we determine the spectrum of the Heisenberg oscillator which is the operator defined as $L + |z|^2$ on the 3-dimensional Heisenberg group $H_1=\mathbb C \times \mathbb R$ where $L$ stands for the positive sublaplacian and $z$ for the complex variable of a point of the group.

Gamma Oscillation by Synaptic Inhibition in a Hippocampal Interneuronal Network Model
Journal of Neuroscience, 1996 Fast neuronal oscillations (gamma, 20–80 Hz) have been observed in the neocortex and hippocampus during behavioral arousal. Using computer simulations, we investigated the hypothesis that such rhythmic activity can emerge in a random network of ...
