Beta cell secreted GABA sets appropriate insulin secretion by modulating islet calcium oscillations [PDF]
Objectives: Gamma-aminobutyric acid (GABA) is produced in pancreatic beta cells and is implicated in modulating islet function, yet its precise physiological role remains uncertain.

Neural oscillations during conditional associative learning [PDF]
AbstractAssociative learning requires mapping between complex stimuli and behavioural responses. When multiple stimuli are involved, conditional associative learning is a gradual process with learning based on trial and error. It is established that a distributed network of regions track associative learning, however the role of neural oscillations in ...

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

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

Minimality Condition and Atmospheric Neutrino Oscillations [PDF]
A structure is proposed for the mass matrices of the quarks and leptons that arises in a natural way from the assumption that the breaking of SO(10) gauge symmetry is achieved by the smallest possible set of vacuum expectation values. This structure explains well many features of the observed spectrum of quarks and leptons.

Non-oscillation of half-linear differential equations with periodic coefficients
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
By the combination of the modified half-linear Prüfer method and the Riccati technique, we study oscillatory properties of half-linear differential equations.

Characterization of information-based learning benefits with submovement dynamics and muscular rhythmicity. [PDF]
For skill advancement, motor variability must be optimized based on target information during practice sessions. This study investigated structural changes in kinematic variability by characterizing submovement dynamics and muscular oscillations after ...

Condition for minimal harmonic oscillator action [PDF]
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.

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