Reviving Oscillations in Coupled Nonlinear Oscillators

Physical Review Letters, 2013
By introducing a processing delay in the coupling, we find that it can effectively annihilate the quenching of oscillation, amplitude death (AD), in a network of coupled oscillators by switching the stability of AD. It revives the oscillation in the AD regime to retain sustained rhythmic functioning of the networks, which is in sharp contrast to the ...

Driven oscillations of a limit-cycle oscillator

Journal of Theoretical Biology, 1980
When a chemical oscillator exhibiting a limit cycle is driven by harmonically modulating one of the rate constants, the oscillations may eventually synchronize with the driving frequency, or the two may beat. Near the transition from beating to phase locking, the oscillation frequency is pulled by the drive.

Chemical oscillator as a generalized Rayleigh oscillator

The Journal of Chemical Physics, 2013
We derive the conditions under which a set of arbitrary two dimensional autonomous kinetic equations can be reduced to the form of a generalized Rayleigh oscillator which admits of limit cycle solution. This is based on a linear transformation of field variables which can be found by inspection of the kinetic equations.

“Oscillating” Metallocene Catalysts:  What Stops the Oscillation?

Journal of the American Chemical Society, 2003
The 150 MHz (13)C NMR microstructural analysis of polypropylene samples produced with two representative "oscillating" metallocene catalysts of largely different steric hindrance, namely [(2-(3,5-di-tert-butyl-4-methoxyphenyl)indenyl)(2)ZrP](+) and [(2-phenylindenyl)(2)ZrP](+) (P = polymeryl), and the implications on the origin of the stereocontrol are

The Audion oscillator

Journal of the American Institute of Electrical Engineers, 1920
18. Operating Point on the Characteristic Curve By operating point on the characteristic curve is meant the point on the E c — I b curve of the audion about which the grid potential and space current vary. E c is the potential of the grid with respect to the filament. If a continuous negative potential such as Q Fig.

“Oscillating” Metallocene Catalysts: How Do They Oscillate?

Angewandte Chemie International Edition, 2002
Based on the results of a series of propylene polymns. using oscillating metallocene catalysts of type [(2-Ar-indenyl)2ZrCl2] (Ar = C6H5 or 3,5-(t-Bu)2-4-MeO-C6H2) with various cocatalysts (MAO, TIBAl), the oscillating behavior of the zirconocenes is discussed with respect to the rac/meso stereochem. outcome of the obtained polypropylenes.

Forced oscillations in oscillator circuits, and the synchronization of oscillators

Journal of the Institution of Electrical Engineers - Part III: Radio and Communication Engineering, 1945
The behaviour of a feedback oscillator circuit under the influence of an injected tone having a frequency close to the natural frequency of oscillation is considered from the point of view of the steady-state equilibrium of the loop transmission circuit.

Simultaneous Oscillations in Oscillators

Transactions of the IRE Professional Group on Circuit Theory, 1954
An oscillator with two degrees of freedom can, under certain conditions, oscillate simultaneously at two different frequencies. The ratio of the two frequencies may be rational (synchronous oscillations) or irrational (asynchronous oscillations). The conditions necessary for 'simultaneous oscillations are discussed for these two cases.

Oscillating electrolytes

ELECTROPHORESIS, 2006
AbstractChemical oscillations are driven by the gradient of the chemical potential so that they can appear in systems where the substances are not in chemical equilibrium. We show that under the influence of the electric field, concentrations of electrically charged substances in solutions can oscillate even if the system is in chemical equilibrium ...
