Surface electromyography to quantify neuro-respiratory drive and neuro-mechanical coupling in mechanically ventilated children

Respiratory Research, 2023
Background The patient’s neuro-respiratory drive, measured as electrical activity of the diaphragm (EAdi), quantifies the mechanical load on the respiratory muscles.

Dynamic Response of a Box Multistage Stiffened Beam under the Coupling of Vehicle Load and Air Blast Load

Buildings, 2023
If a bridge is subjected to a blast load when there is vehicle traffic, not only its own safety is threatened, but it can also lead to damage to vehicles.

Coupling impedance of a periodic array of diaphragms [PDF]

Proceedings Particle Accelerator Conference, 2002
The method is presented for calculating the high-frequency longitudinal transverse coupling impedances in a periodic array of diaphragms in a circular perfectly conducting pipe. The method is based on Weinstein's theory of diffraction of a plane electromagnetic wave on a stack of halfplanes.

Development of a controlled environment near-field optical microscope for organic thin film studies [PDF]

, 2010
The requirements of a microscope differ greatly from field to field and with the sample being studied Organic thin films are highly sensitive to environmental conditions being rapidly photobleached in the presence of oxygen In this paper we introduce the

Unidirectional mechanical amplification as a design principle for an active microphone

, 2011
Amplification underlies the operation of many biological and engineering systems. Simple electrical, optical, and mechanical amplifiers are reciprocal: the backward coupling of the output to the input equals the forward coupling of the input to the ...
