Analysis of High-Frequency Oscillation Propagation Path Based on Branch High-Frequency Power Distribution

open access: yesEnergies
While the generation mechanisms of high-frequency oscillations caused by voltage source converter-based high-voltage direct current (VSC-HVDC) systems have been widely investigated, their propagation paths and spatial influence within the power grid ...

Research on the Hydrodynamic Performance of a Vertical Axis Current Turbine with Forced Oscillation

open access: yesEnergies, 2018
For a current turbine fixed on a floating platform, the wave-induced motion responses of the platform change the hydrodynamic performance of the current turbine.

The Response of a Conical Laminar Premixed Flame to Equivalence Ratio Oscillations in Rich Conditions

open access: yesJournal of Thermal Science and Technology, 2013
Responses of conical premixed methane/air mixture flames with equivalence ratio oscillations were numerically investigated at three different oscillation frequency regimes; low, medium and high (10, 50 and 150 s-1) under a rich condition.

A Stability Criterion for High-Frequency Oscillations [PDF]

open access: yesMémoires de la Société mathématique de France, 2015
We show that a simple Levi compatibility condition determines stability of WKB solutions to semilinear hyperbolic initial-value problems issued from highly-oscillating initial data with large amplitudes. The compatibility condition involves the hyperbolic operator, the fundamental phase associated with the initial oscillation, and the semilinear source

From optical parametric oscillation to frequency-comb generation in whispering gallery resonators made of CdSiP2

open access: yes, 2022
Paper 1167004, 6 S.Microresonator frequency combs have seen remarkable progress in the past decade. In this work, we investigate optical parametric oscillation in a mm-sized cadmium silicon phosphide (CdSiP2) whispering gallery resonator for X(2 ...

Analysis and suppression of voltage oscillation at DC circuit breaker terminal in DC fault transient process

open access: yesHigh Voltage, 2022
High‐frequency voltage oscillation occurs at the initial stage of DC short‐circuit fault in the modular multilevel converter (MMC)‐based high‐voltage direct‐current systems, which directly threatens the reliable operation of the secondary equipment in DC

High frequency oscillations in the intact brain [PDF]

open access: yesProgress in Neurobiology, 2012
High frequency oscillations (HFOs) constitute a novel trend in neurophysiology that is fascinating neuroscientists in general, and epileptologists in particular. But what are HFOs? What is the frequency range of HFOs? Are there different types of HFOs, physiological and pathological? How are HFOs generated?

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells
