Forced Oscillations in Fluid Tori and Quasi-Periodic Oscillations

, 2005
The kilo-Hertz Quasi--Periodic Oscillations in X-ray binaries could originate within the accretion flow, and be a signature of non--linear fluid oscillations and mode coupling in strong gravity.

Detection and Reconstruction of Bursting Oscillations in Complex Systems Using the HAVOK Analysis Framework

Algorithms
Multi-scale dynamical systems may exhibit bursting oscillations, which are typically identified by analyzing time series and phase portraits. However, in cases where bursting oscillations are not apparent, relying solely on these methods may have ...

Suppression of amplitude dependent closest tune approach and its behavior under forced oscillations

Physical Review Accelerators and Beams, 2019
An amplitude dependent closest tune approach (ADeCTA) was first observed in the LHC in 2012. This potentially harmful effect can be generated by linear coupling in conjunction with octupoles.

Multum non multa: airway distensibility by forced oscillations

Monaldi Archives for Chest Disease, 2016
Airway distensibility although appears to be unaffected by airway smooth muscle tone probably related to airway remodelling, after bronchodilator treatment is significantly increased in subjects with asthma.

Chirped Bloch-harmonic oscillations in a parametrically forced optical lattice

Physical Review Research, 2023
The acceleration theorem for wave packet propagation in periodic potentials disentangles the k-space dynamics and real space dynamics. This is well known and understood for Bloch oscillations and super Bloch oscillations in the presence of position ...

Relationship between pressure variations at the ocean bottom and the acceleration of its motion during a submarine earthquake

Earth, Planets and Space, 2018
The data provided by ten DONET deep-sea observatories, that on March 11, 2011, registered the Great East Japan Earthquake and tsunami, were used for investigation of the relationship between variations of the ocean bottom pressure and three-component ...

Forced oscillations in a hydrodynamical accretion disk and QPOs

, 2005
This is the second of a series of papers aimed to look for an explanation on the generation of high frequency quasi-periodic oscillations (QPOs) in accretion disks around neutron star, black hole, and white dwarf binaries.

Forced and self-excited oscillations of an optomechanical cavity [PDF]

, 2011
We experimentally study forced and self oscillations of an optomechanical cavity which is formed between a fiber Bragg grating that serves as a static mirror and between a freely suspended metallic mechanical resonator that serves as a moving mirror.

Synthesis of a Novel Thermoresponsive S53P4 Bioactive Glass Extract–Poloxamer 407 Injectable Hydrogels: Assessment of Biocompatibility and Antimicrobial Properties

Advanced Engineering Materials, EarlyView.
This study investigates innovative thermoreversible hydrogels derived from S53P4 bioactive glass extracts to aid in the healing of infected diabetic foot wounds. These injectable gels, which gel at body temperature, release beneficial ions and remain stable over time.
