Standing waves braneworlds [PDF]

International Journal of Modern Physics D, 2016
The class of nonstationary braneworld models generated by the coupled gravitational and scalar fields is reviewed. The model represents a brane in a spacetime with single time and one large (infinite) and several small (compact) spacelike extra dimensions.

Diagnostic accuracy of the response to the brief tachycardia provoked by standing in children suspected for long QT syndrome

Heart Rhythm O2, 2021
Background: Adult long QT syndrome (LQTS) patients have inadequate corrected QT interval (QTc) shortening and an abnormal T-wave response to the sudden heart rate acceleration provoked by standing.

A paradigm shift in the quantification of wave energy attenuation due to saltmarshes based on their standing biomass

Scientific Reports, 2022
Most existing analytical and numerical models to quantify wave energy attenuation attributed to saltmarshes are based on the definition of a drag coefficient that varies with vegetation and wave characteristics and requires calibration, i.e., a case ...

Researched on the bias stability of the HRG affected by the temperature and the standing wave azimuth

Measurement + Control, 2020
The force-to-rebalanced control mode is the main operating mechanism of the HRG, and the standing wave azimuth of the resonator points to the 0° direction. But the bias of the HRG is very sensitive to the change of external physical field environment and

Dynamics of an acoustically trapped sphere in beating sound waves

Physical Review Research, 2021
A focused acoustic standing wave creates a Hookean potential well for a small sphere and can levitate it stably against gravity. Exposing the trapped sphere to a second transverse traveling sound wave imposes an additional acoustic force that drives the ...

Human Standing Posture Motion Evaluation by the Visual Simulation of Multi-Directional Sea-Waves

Sensors, 2022
Crew fatigue from standing posture motion, caused by ship motion, can lead to marine accidents. Therefore, the mechanism of fatigue in crew members ought to be elucidated.

Standing wave Spectrometer

Optics Express, 2010
A standing wave Fourier transform spectrometer is realized. The spectrometer consists of an ultra thin and partially transparent photodetector and a tunable mirror. The incident light forms a standing wave in front of the mirror, which is sampled by the ultra thin optical detector.
