High-Frequency Oscillatory Ventilation as a Rescue Mode for Refractory Hypercarbia in Children
Tokyo Women's Medical University Journal, 2022 High-frequency oscillatory ventilation (HFOV) use in the airway obstructive status can be relatively contraindicated by the risk of air trapping leading to hemodynamic compromise.

OSCILLATORY ROLL OF THE ROAD ROLLER WITH A DOUBLE SIDE PLATE
Вестник СибАДИ, 2019 Introduction. Soil compaction plays a crucial role in the construction of road foundations. The quality of this process is influenced by the type and modes of application of external force from the seal.

Progress in Particle and Nuclear Physics, 2013 This review summarizes recent experimental and theoretical progress in determining neutrino mixing angles and masses through neutrino oscillations. We describe the basic physics of oscillation phenomena in vacuum and matter, as well as the status of solar, reactor, atmospheric, and accelerator neutrino experiments that probe these phenomena.

Philosophical Transactions of the Royal Society B: Biological Sciences, 2019 Cilia, or eukaryotic flagella, are microscopic active filaments expressed on the surface of many eukaryotic cells, from single-celled protozoa to mammalian epithelial surfaces. Cilia are characterized by a highly conserved and intricate internal structure in which molecular motors exert forces on microtubule doublets causing cilia oscillations.

A Low Power Low Phase Noise Oscillator for MICS Transceivers
Sensors, 2017 A low-power, low-phase-noise quadrature oscillator for Medical Implantable Communications Service (MICS) transceivers is presented. The proposed quadrature oscillator generates 349~689 MHz I/Q (In-phase and Quadrature) signals covering the MICS band. The

Photothermocapillary Oscillators
Physical Review Letters, 2018 We present a new class of tunable light-driven oscillators based on mm-scale objects adsorbed at fluid interfaces. A fixed light source induces photothermal surface tension gradients (Marangoni stresses) that drive nanocomposite hydrogel discs away from a stable apex position atop a drop of water.
