RELAXATION OSCILLATIONS OF THE SUPERLUMINESCENCE IN THE SEMICONDUCTOR

Вестник. Серия физическая, 2009
The intensity modulation of superluminescence with a period of about 1 picosecond in a semiconductor subject to an ultra-short high-power light pulse is shown to occur due to relaxation oscillations of radiation caused by local perturbations of quasi ...

Tight coupling of metabolic oscillations and intracellular water dynamics in Saccharomyces cerevisiae.

PLoS ONE, 2015
We detected very strong coupling between the oscillating concentration of ATP and the dynamics of intracellular water during glycolysis in Saccharomyces cerevisiae.

Continuity, Discontinuity and Dynamics in Mathematics & Economics - Reconsidering Rosser's Visions [PDF]

Barkley Rosser has been a pioneer in arguing the case for the mathematics of discontinuity, broadly conceived, to be placed at the foundations of modelling economic dynamics. In this paper we reconsider this vision from the broad perspective of a variety

Calculation of Relaxation Spectra from Stress Relaxation Measurements [PDF]

, 2010
Application of stress on materials increases the energy of the system. After removal of stress, macromolecules comprising the material shift towards equilibrium to minimize the total energy of the system.

Structured relaxation in the treatment of akathisia: case series

, 2010
Purpose: Akathisia remains a common side effect especially from antipsychotic medication.If the condition is diagnosed the management options are limited.Subjects/methodology: We tested a structured relaxation program on nine patients with adiagnosis of ...

On Problems Solved in a Quasi-Linear Approximation

Mathematics
The complete analytic solution of the time-dependent Vlasov–Boltzmann kinetic equation is used to describe selected problems in plasma physics within the framework of the quasi-linear approximation. These problems usually include the relaxation of plasma

Relaxation oscillations in long-pulsed random lasers [PDF]

, 2009
We have measured the evolution of the intensity emitted by a random laser during a pump pulse that is comparable in duration to the spontaneous emission decay time.

Dynamic relaxation oscillations in a nonlinearly driven quartz crystal

, 2015
We demonstrate thermo-mechanical relaxation oscillations in a strongly driven quartz crystal. Dynamic bifurcation leads to two stable oscillation states with a distinct electrical impedance.

Voltage oscillations in SOI transistors as generators

Технологія та конструювання в електронній апаратурі, 2005
Voltage and current oscillations in field-effect transistors fabricated using silicon-on-insulator (SOI) technology have been investigated. It has been shown that by changing the transistor’s supply conditions, the oscillation frequency can be varied ...

Relaxation Oscillations in a System with Delays Modeling the Predator-Prey Problem

Моделирование и анализ информационных систем, 2013
A new asymptotic method for investigating complex relaxation oscillations of a system with delay was offered. Applying it, we can reduce the problem of predator-prey system dynamics to problem of one-dimensional maps analysis.
