The performance of multi-hop parallel free-space optical (FSO) communication systems with decode-and-forward (DF) protocol over exponentiated Weibull (EW) fading channels has been investigated. Average bit error rate (ABER) and outage probability (OP) performance are analyzed under different turbulence conditions, receiver aperture size and structure parameters (R, C). The ABER and OP for FSO s...

A 54-story steel, perimeter-frame building in downtown Los Angeles, California, is identified by a wave method using records of the Northridge earthquake of 1994 (ML=6.4, R=32 km). The building is represented as a layered shear beam and a torsional shaft, characterized by the corresponding velocities of vertically propagating waves through the structure. The previously introduced waveform inver...

The college years represent an important developmental period in the lives of young women, who report health-related difficulties such as sleep disturbance and body/eating concerns. This study explored whether expressive writing (EW) can decrease health-relevant complaints among college women. College females (n = 111) were randomised into an EW condition (writing about body concerns) or a cont...

OBJECTIVE This study was conducted to investigate the effects of weaning times on the growth performance, rumen fermentation and microbial communities of yellow cattle calves. METHODS Eighteen calves were assigned to a conventional management group that was normally weaned (NW, n = 3) or to early weaned (EW) group where calves were weaned when the feed intake of solid feed (starter) reached 5...

Electrowetting (EW)-induced droplet motion has been studied over the last decade in view of its promising applications in the field of microfluidics. The objective of the present work is to analyze the physics underlying two specific EW-based applications for microelectronics thermal management. The first of these involves heat absorption by liquid droplets moving on the surface of a chip under...

Methylene blue (MB), a tricyclic phenothiazine drug, has been reported to enhance mitochondrial functions including mitochondrial respiration. By comparison, stress associated with abrupt ethanol withdrawal (EW) impedes mitochondrial functions. We investigated whether MB protects mitochondrial respiration and cell survival from EW stress through a key mitochondrial enzyme, cytochrome c oxidase ...

We have witnessed rapid and exciting development in electrowetting (EW) or electrowetting-on-dielectric (EWOD) since 1990s. Owing to its great advantages such as easy operation, sensitive response and electrical reversibility, EW has found many applications in various fi elds, especially in microand nano-fl uidics, electronic display, etc. The aim of this review is to inspire new investigations...

A standard introduction to online learning might place Online Gradient Descent at its center and then proceed to develop generalizations and extensions like Online Mirror Descent and secondorder methods. Here we explore the alternative approach of putting exponential weights (EW) first. We show that many standard methods and their regret bounds then follow as a special case by plugging in suita...

BACKGROUND Electromechanical wave imaging (EWI) is an entirely noninvasive, ultrasound-based imaging method capable of mapping the electromechanical activation sequence of the ventricles in vivo. Given the broad accessibility of ultrasound scanners in the clinic, the application of EWI could constitute a flexible surrogate for the 3-dimensional electrical activation. OBJECTIVE The purpose of ...
