Coupled-Oscillators [PDF]

open access: yesInternational Astronomical Union Colloquium, 1993
AbstractModal coupling oscillation models for the stellar radial pulsation and coupled-oscillators are reviewed. Coupled-oscillators with the second-order and third-order terms seemed to behave non-systematically. Using the equation by Schwarzschild and Savedoff (1949) with the dissipation term of van del Pol’s type which is third-order, we demonstrate

Distinct Signatures For Coulomb Blockade and Aharonov-Bohm Interference in Electronic Fabry-Perot Interferometers [PDF]

open access: yes, 2008
Two distinct types of magnetoresistance oscillations are observed in two electronic Fabry-Perot interferometers of different sizes in the integer quantum Hall regime.

Interminiband Rabi oscillations in biased semiconductor superlattices [PDF]

open access: yes, 2007
Carrier dynamics at energy level anticrossings in biased semiconductor superlattices, was studied in the time domain by solving the time-dependent Schroedinger equation.

Task-related activity in sensorimotor cortex in Parkinson’s disease and essential tremor: changes in beta and gamma bands

open access: yesFrontiers in Human Neuroscience, 2015
In Parkinson’s disease patients in the OFF medication state, basal ganglia local field potentials exhibit changes in beta and gamma oscillations that correlate with reduced voluntary movement, manifested as rigidity and akinesia.

Oscillations support short latency co-firing of neurons during human episodic memory formation

open access: yeseLife, 2022
Theta and gamma oscillations in the medial temporal lobe are suggested to play a critical role for human memory formation via establishing synchrony in neural assemblies. Arguably, such synchrony facilitates efficient information transfer between neurons

Discovery of nearly coherent oscillations with a frequency of ~567 Hz during type-I X-ray bursts of the X-ray transient and eclipsing binary X 1658-298

open access: yes, 2001
We report the discovery of nearly coherent oscillations with a frequency of 567 Hz during type-I X-ray bursts from the X-ray transient and eclipsing binary X 1658-298.

OSCILLATING FILAMENTS. I. OSCILLATION AND GEOMETRICAL FRAGMENTATION [PDF]

open access: yesThe Astrophysical Journal, 2017
ABSTRACT We study the stability of filaments in equilibrium between gravity and internal as well as external pressure using the grid-based AMR code RAMSES. A homogeneous, straight cylinder below a critical line mass is marginally stable. However, if the cylinder is bent, such as with a slight sinusoidal perturbation, an otherwise stable ...

Oscillatory Correlates of Visual Consciousness

open access: yesFrontiers in Psychology, 2017
Conscious experiences are linked to activity in our brain: the neural correlates of consciousness (NCC). Empirical research on these NCCs covers a wide range of brain activity signals, measures, and methodologies.

Phase separation of competing memories along the human hippocampal theta rhythm

open access: yeseLife, 2022
Competition between overlapping memories is considered one of the major causes of forgetting, and it is still unknown how the human brain resolves such mnemonic conflict.

Coherent magneto-elastic oscillations in superfluid magnetars

open access: yes, 2016
We study the effect of superfluidity on torsional oscillations of highly magnetised neutron stars (magnetars) with a microphysical equation of state by means of two-dimensional, magnetohydrodynamical- elastic simulations. The superfluid properties of the
