We analyze the dynamics of the neural circuit of the lamprey central pattern generator. This analysis provides insight into how neural interactions form oscillators and enable spontaneous oscillations in a network of damped oscillators, which were not apparent in previous simulations or abstract phase oscillator models. We also show how the different behavior regimes (characterized by phase and...

We propose a unified model to explain Quasi-Periodic-Oscillation (QPO), particularly of high frequency, observed from black hole and neutron star systems globally. We consider accreting systems to be damped harmonic oscillators exhibiting epicyclic oscillations with higher order nonlinear resonance to explain QPO. The resonance is expected to be driven by the disturbance from the compact object...

The oscillators based on an active transmission line periodically loaded with RTD pairs are studied using circuit simulation with special attention to the behavior of harmonics. Generation of strong high order harmonic (9th) was observed. This is caused by the frequency locking in the high frequency passband. The harmonic oscillators based on this phenomenon are promising for high performance T...

The Bertrand-Darboux integrability condition for a certain class of perturbed harmonic oscillators is studied from the viewpoint of the Birkhoff-Gustavson(BG)-normalization: By solving an inverse problem of the BG-normalization on computer algebra, it is shown that if the perturbed harmonic oscillator with a homogeneous cubic-polynomial potential and the perturbed harmonic oscillator with a hom...

We address the problem of removing correlation from sets of states while preserving as much local quantum information as possible. We prove that states obtained from universal cloning can only be decorrelated at the expense of complete erasure of local information (i.e., information about the copied state). We solve analytically the problem of decorrelation for two qubits and two qumodes (harmo...

This paper deals with the accuracy of a numerical time integration scheme, the implicit Generalizedα method, when applied near resonant conditions in periodic steady-state vibrations of elastic linear and nonlinear systems. In order to evaluate errors, analytical solutions of Frequency Response Functions (FRFs) are determined by using the Harmonic Balance method in singleand two-degrees-of-free...

In this investigation, some analytical solutions to both conserved and non-conserved rotational pendulum systems are reported. The exact solution the oscillator (unforced, undamped oscillator), is derived in form of a Jacobi elliptical function. Moreover, an approximate for case obtained trigonometric A comparison between examined. approximations oscillators including unforced, damped forced, o...
