High Frequency Oscillations in SS Cygni [PDF]

open access: yesInternational Astronomical Union Colloquium, 1989
Because of its relative brightness (mv about 11.8 in quiescence and mv about 8.6 in outburst), SS Cygni is the Dwarf Novae most extensively studied since 1896 (Mattei et al., 1985; Bath and van Paradijs, 1983).Concerning its long-term behaviour, SS Cygni has short, long and anomalous out-bursts.

High-frequency oscillations and the neurobiology of schizophrenia [PDF]

open access: yesDialogues in Clinical Neuroscience, 2013
Neural oscillations at low- and high-frequency ranges are a fundamental feature of large-scale networks. Recent evidence has indicated that schizophrenia is associated with abnormal amplitude and synchrony of oscillatory activity, in particular, at high (beta/gamma) frequencies.

High-Frequency Oscillations and Epileptogenic Network

open access: yesCurrent Neuropharmacology, 2022
Abstract: Epilepsy is a network disease caused by aberrant neocortical large-scale connectivity spanning regions on the scale of several centimeters. High-frequency oscillations, characterized by the 80-600 Hz signals in electroencephalography, have been proven to be a promising biomarker of epilepsy that can be used in assessing the severity and ...

Precision measurement of the B[0 over s]–[– over B][0 over s] oscillation frequency with the decay B[0 over s]→D[– over s]π[superscript +] [PDF]

open access: yes, 2013
A key ingredient to searches for physics beyond the Standard Model in B[0 over s] mixing phenomena is the measurement of the B[0 over s]–[– over B][0 over s] oscillation frequency, which is equivalent to the mass difference Δm[subscript s] of the B[0 ...

High-frequency oscillations in epileptic brain [PDF]

open access: yesCurrent Opinion in Neurology, 2010
It has been 10 years since pathological high-frequency oscillations (pHFOs) were described in the brain of epileptic animals and patients. This review summarizes progress in research on mechanisms of their generation and potential clinical applications over that period.Initially, pHFOs were recorded with microelectrodes in the hippocampus of rodents ...

The relationship between the SOI and extended tropical precipitation in simulations of future climate change [PDF]

open access: yes, 2002
The Southern Oscillation Index (SOI), its relationship with precipitation, and how greenhouse gas-induced changes in climate may modify these relationships has been examined in 12 coupled atmosphere-ocean Global Climate Model (GCM) experiments. The model

Mechanism Analysis and Suppression Strategy of Continuous High-Frequency Oscillation in MMC-HVDC System

open access: yes, 2022
The continuous high-frequency oscillation phenomenon of the MMC-HVDC system occurs frequently in practical engineering. How to design an effective oscillation suppression strategy based on the essential mechanism of continuous oscillation has not been ...

Adaptive diagnosis of the bilinear mechanical systems [PDF]

open access: yes, 2009
A generic adaptive approach is proposed for diagnosis of the bilinear mechanical systems. The approach adapts the free oscillation method for bilinearity diagnosis of mechanical systems.

Precise determination of the Bs0 – B¯s0 oscillation frequency [PDF]

open access: yes, 2022
Mesons comprising a beauty quark and strange quark can oscillate between particle (Bs0) and antiparticle (B¯s0) flavour eigenstates, with a frequency given by the mass difference between heavy and light mass eigenstates, Δms.
