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

Finite oscillator models: the Hahn oscillator [PDF]
A new model for the finite one-dimensional harmonic oscillator is proposed based upon the algebra u(2)_ . This algebra is a deformation of the Lie algebra u(2) extended by a parity operator, with deformation parameter . A class of irreducible unitary representations of u(2)_ is constructed.

Revival of oscillation and symmetry breaking in coupled quantum oscillators [PDF]
Restoration of oscillation from an oscillation suppressed state in coupled oscillators is an important topic of research and has been studied widely in recent years. However, the same in the quantum regime has not been explored yet. Recent works established that under certain coupling conditions coupled quantum oscillators are susceptible to ...

Pathological high frequency oscillations (250-600Hz) are present in the brains of epileptic animals and humans. The etiology of these oscillations and how they contribute to the diseased state remains unclear.

Reconfigurable Mechanical Vibrations Laboratory Kit
Mechanical vibrations appear across a diverse range of applications, but nevertheless are unified by a core set of principles and phenomena. In this article, we describe a reconfigurable laboratory kit that is designed to be used as part of a first ...

On the difference equation zm+1 = f(zm, zm-1, …, zm–k)
In the present work, we investigate the stability, periodicity and oscillation of the solution for a new general class of difference equations. Actually, this is the most general form of linear difference equations.

Experiments in rodent models of Parkinson's Disease have demonstrated a prominent increase of oscillatory firing patterns in neurons within the Parkinsonian globus pallidus (GP) which may underlie some of the motor symptoms of the disease.
