Self- excited oscillation under the influence of non - linear frictions

open access: yesVietnam Journal of Mechanics, 1982
In this article the influence of friction R1, R2 on Van der Pol oscillator is considered. It turned out that the mentioned frictions decrease the amplitude of self – excited oscillations and they stabilize the equilibrium position of the self – excited ...

On the Oscillation of Impulsive Neutral First-order Differential Equations with Variable Arguments

open access: yesJournal of Scientific Research in Science, 2022
Throughout the article, we study the oscillation of a general class of first-order neutral differential equations in presence of variable delays under the effect of impulses.

A non-oscillation theorem for differential matrix systems

open access: yesJournal of Mathematical Analysis and Applications, 2005
Excellently written, the paper deals with a Wintner-Hille-Opial-type nonoscillation result for the matrix differential equation \(Y^{\prime \prime }+Q(t)Y=0\), \(t\geq a\), where \(Q(t)\) is a real, \(n\times n\), continuous, symmetric matrix function.

Impacts of the Madden-Julian oscillation on Australian rainfall and circulation [PDF]

open access: yes, 2009
Impacts of the Madden¿Julian oscillation (MJO) on Australian rainfall and circulation are examined during all four seasons. The authors examine circulation anomalies and a number of different rainfall metrics, each composited contemporaneously for eight ...

Effective-parametric resonance in a non-oscillating system

open access: yesEPL (Europhysics Letters), 2012
We present a mechanism for the generation of oscillations and nonlinear parametric amplification in a non-oscillating system, which we term effective-parametric resonance. Sustained oscillations appear at a controlled amplitude and frequency, related directly to the external forcing parameters.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
