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 ...

Half-linear Euler differential equation and its perturbations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
We investigate oscillatory properties of perturbed half-linear Euler differential equation. We give an alternative proof (simpler and more straightforward) of the main result of [O. Došlý, H. Funková, Abstr. Appl. Anal. 2012, Art. ID 738472] and we prove

Oscillation and nonoscillation of higher order self-adjoint differential equations [PDF]

open access: yes, 1997
summary:Oscillation and nonoscillation criteria for the higher order self-adjoint differential equation \[ (-1)^n(t^{\alpha }y^{(n)})^{(n)}+q(t)y=0 \qquad \mathrm{(*)}\] are established.

An Adaptive-to-Model Test for Parametric Functional Single-Index Model

open access: yesMathematics, 2023
Model checking methods based on non-parametric estimation are widely used because of their tractable limiting null distributions and being sensitive to high-frequency oscillation alternative models.

Condition for minimal harmonic oscillator action [PDF]

open access: yesAmerican Journal of Physics, 2017
We provide an elementary proof that the action for the physical trajectory of the one-dimensional harmonic oscillator is guaranteed to be a minimum if and only if τ<π/ω, where τ is the elapsed time and ω is the oscillator's natural frequency.

Estimating extreme flood events – assumptions, uncertainty and error [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2015
Hydrological extremes are amongst the most devastating forms of natural disasters both in terms of lives lost and socio-economic impacts. There is consequently an imperative to robustly estimate the frequency and magnitude of hydrological extremes ...

Study of the oscillation condition of quartz oscillators by gyrator transformation [PDF]

open access: yesProceedings of the 2000 IEEE/EIA International Frequency Control Symposium and Exhibition (Cat. No.00CH37052), 2002
The calculation of the oscillation condition is one of the main points of oscillator analysis. Its determination in finite terms allows one to calculate the steady state amplitude and frequency of the oscillator. Symbolic solutions provide an additional insight into the behavior of the circuit.

Euler type linear and half-linear differential equations and their non-oscillation in the critical oscillation case

open access: yesJournal of Inequalities and Applications, 2019
This paper is devoted to the analysis of the oscillatory behavior of Euler type linear and half-linear differential equations. We focus on the so-called conditional oscillation, where there exists a borderline between oscillatory and non-oscillatory ...
