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.

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.

On Free Oscillations of a Quadratic Nonlinear Oscillator [PDF]
Ukrainian Journal of Mechanical Engineering and Materials Science, 2017 A free oscillations of a system with one degree of freedom, caused either by the initial deviation from the stable equilibrium position or by the initial velocity provided by the oscillator in this position was considered. Analytical solutions of the nonlinear Cauchy problem for a second-order differential equation were constructed.

Oscillators and Oscillations in the Basal Ganglia [PDF]
The Neuroscientist, 2014 What is the meaning of an action potential? There must be different answers for neurons that fire spontaneously, even in the absence of synaptic input, and those driven to fire from a resting membrane potential. In spontaneously firing neurons, the occurrence of the next action potential is guaranteed; only variations in its timing can carry the ...

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
