Characterizing Intermittency of 4-Hz Quasi-periodic Oscillation in XTE J1550-564 using Hilbert-Huang Transform [PDF]
, 2015 We present the time-frequency analysis results based on the Hilbert-Huang transform (HHT) for the evolution of a 4-Hz low-frequency quasi-periodic oscillation (LFQPO) around the black hole X-ray binary XTE J1550-564. The origin of LFQPOs is still debated.

LOW-FREQUENCY SWASH OSCILLATION
Doboku Gakkai Ronbunshu, 1993 Swash oscillation の周期は入射波のそれに比べて長くなることが知られている. こうした swash oscillation の長周期化を水理実験および有限振幅長波理論に基づく数値モデルにより検討し, 長周期波のほかに, swash zone での寄せ波と引き波の時系列に依存する追い付き・合体・吸収といった相互干渉によっても長周期の swash oscillation が形成されることを示した.

Current self-oscillations, spikes and crossover between charge monopole and dipole waves in semiconductor superlattices [PDF]
, 1999 Self-sustained current oscillations in weakly-coupled superlattices are studied by means of a self-consistent microscopic model of sequential tunneling including boundary conditions naturally.

The occurrence mechanism and damping method of ultra‐low‐frequency oscillations
IET Renewable Power Generation, 2021 The ultra‐low‐frequency oscillation (ULFO) problem has reappeared in China recently. Although the hydraulic generator is supposed to have a strong connection to this problem, the conditions for ULFO appearance and detailed reasons are not clear yet.

A model for the onset of oscillations near the stopping angle in an inclined granular flow
, 2012 We propose an explanation for the onset of oscillations seen in numerical simulations of dense, inclined flows of inelastic, frictional spheres. It is based on a phase transition between disordered and ordered collisional states that may be interrupted ...

Frontiers in Neurology, 2014 Sinusoidal galvanic vestibular stimulation (sGVS) induces oscillations in blood pressure (BP) and heart rate (HR) i.e., vasovagal oscillations, and decreases in BP and HR i.e., vasovagal responses, in isoflurane-anesthetized rats.

Persistent Rabi oscillations probed via low-frequency noise correlation
, 2010 The qubit Rabi oscillations are known to be non-decaying (though with a fluctuating phase) if the qubit is continuously monitored in the weak-coupling regime.

KiloHertz quasi-periodic oscillations difference frequency exceeds inferred spin frequency in 4U 1636-53 [PDF]
, 2002 Recent observations of the low-mass X-ray binary 4U 1636-53 with the Rossi X-ray Timing Explorer show, for the first time, a kiloHertz quasi-periodic oscillation (kHz QPO) peak separation that exceeds the neutron star spin frequency as inferred from ...
