Oscillation and non-oscillation of half-linear differential equations with coeffcients determined by functions having mean values

open access: yesOpen Mathematics, 2018
The paper belongs to the qualitative theory of half-linear equations which are located between linear and non-linear equations and, at the same time, between ordinary and partial differential equations.

Hybrid CNN-BiLSTM-Attention Conditional GAN for power system forced oscillation localization

open access: yesInternational Journal of Electrical Power & Energy Systems
Data-driven methods for Forced Oscillation (FO) sources localization in power systems face challenges including limited dataset size, class imbalance, and high data acquisition costs, which limit the ability to train large and sophisticated deep learning

Neither/nor: a pragmatic philosophy for oscillating between conceptual and experiential knowledge [PDF]

open access: yesHumanities & Social Sciences Communications
This paper presents “Neither/Nor,” a philosophical synthesis which defines conceptual and experiential modes of knowing as complementary skills which can be deliberately trained and oscillated. The paper argues that neither theory (concepts) nor practice

Oscillations in a nonlinear spring mechanism with one degree of freedom [PDF]

open access: yesMATEC Web of Conferences, 2020
A new method for studying dynamics in a nonlinear spring- loaded mechanism is described, which consists in describing a spring as an elastic solid rod with conditional density and elastic modulus.

Assessment of Inflation Schemes on Parameter Estimation and Their Application in ENSO Prediction in an OSSE Framework

open access: yesJournal of Marine Science and Engineering, 2023
The ensemble Kalman filter is often used in parameter estimation, which plays an essential role in reducing model errors. However, filter divergence is often encountered in an estimation process, resulting in the convergence of parameters to the improper

Non-oscillation of half-linear differential equations with periodic coefficients

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
We consider half-linear Euler type differential equations with general periodic coefficients. It is well-known that these equations are conditionally oscillatory, i.e., there exists a border value given by their coefficients which separates oscillatory ...

Oscillation and non-oscillation criterion for Riemann–Weber type half-linear differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
By the combination of the modified half-linear Prüfer method and the Riccati technique, we study oscillatory properties of half-linear differential equations.

Circadian regulation of dentate gyrus excitability mediated by G-protein signaling

open access: yesCell Reports, 2023
Summary: The central circadian regulator within the suprachiasmatic nucleus transmits time of day information by a diurnal spiking rhythm driven by molecular clock genes controlling membrane excitability.

The Impact of Madden - Julian Oscillation and Sea Surface Temperature Process Interaction on Rainfall Variability During Rainy Season: A Case Study in East Nusa Tenggara, Indonesia [PDF]

open access: yesE3S Web of Conferences, 2023
Most studies of the impact of sea surface temperature (SST) have explored rainfall in a part of Indonesia. This paper takes a different approach and explores the impact of air-sea coupling interaction between Madden-Julian Oscillation (MJO) and SST on ...
