Unusual Vestibulo-Ocular Reflex Responses in Patients With Peripheral Vestibular Disorders Detected by the Caloric Step Stimulus Test

Frontiers in Neurology, 2020
The caloric step stimulus test consists of the changes in head position from the sitting to supine positions and continuous caloric irrigation. This test can provide a single labyrinth with a stimulus similar to constant head acceleration in rotational ...

Driving Waveform Design of Electrowetting Displays Based on an Exponential Function for a Stable Grayscale and a Short Driving Time

Micromachines, 2020
The traditional driving waveform of the electrowetting display (EWD) has many disadvantages, such as the large oscillation of the target grayscale aperture ratio and a long time for achieving grayscale.

Cosmological constant and time delay [PDF]

, 2008
The effect of the cosmological constant on the time delay caused by an isolated spherical mass is calculated without using the lens equation and compared to a recent observational bound on the time delay of the lensed quasar SDSS J1004+4112.Comment: 8 ...

Design of a novel fast turn-off circuit of transient electromagnetic transmitter

Gong-kuang zidonghua, 2016
In view of problem that turn-off time of emission current of transient electromagnetic transmitter is overlong caused by parasitic inductance of the transmitter coils, a novel fast turn-off circuit was designed. During the decline of transmitting current,

Coasting cosmologies with time dependent cosmological constant [PDF]

, 1998
The effect of a time dependent cosmological constant is considered in a family of scalar tensor theories. Friedmann-Robertson-Walker cosmological models for vacumm and perfect fluid matter are found.

Compact phase space, cosmological constant, discrete time [PDF]

, 2015
We study the quantization of geometry in the presence of a cosmological constant, using a discretiza- tion with constant-curvature simplices. Phase space turns out to be compact and the Hilbert space finite dimensional for each link.

Tolerance to high-intensity intermittent running exercise: do oxygen uptake kinetics really matter?

Frontiers in Physiology, 2012
We examined the respective associations between aerobic fitness (VO2max), metabolic control (VO2 kinetics) and locomotor function and various physiological responses to high-intensity intermittent running exercise (HIT) in team sport players.
