Neutrophil (PMN) activation and recruitment are coordinated by ligand-operated surface receptors. These responses are involved in the tissue injury that follows hypoxia/reoxygenation. Here, we report that inflammatory mediators each evoke distinct and characteristic extracellular acidification rates (EAR) in both PMN and endothelial cells (EC) as measured by a Cytosensor microphysiometer. Leuko...

32 THE HEARING REVIEW AUGUST 2004 reach the right ear a bit sooner than it will reach the left ear. It will also be slightly louder in the right than in the left ear. This head diffraction effect will enhance speech intelligibility in noise when speech and noise come from different sides of the head, because the brain can selectively attend to the ear with a better signal-to-noise ratio (SNR) f...

Title of Document: FLY-EAR INSPIRED MINIATURE SENSOR SYSTEM FOR TWO-DIMENSIONAL SOUND SOURCE LOCALIZATION Andrew P. Lisiewski, Master of Science, 2011 Directed By: Associate Professor Miao Yu Sensors and Actuators Laboratory Department of Mechanical Engineering A micro-scale sound localization sensor is developed and studied in this thesis to address the fundamental challenge of miniaturizing s...

This study aimed to evaluate practical barriers to personal protective equipment (PPE) use found through health care personnel (HCP) training sessions held during and after the 2015 Middle East respiratory syndrome outbreak in Korea. Difficulties observed were ill-fitting sizes, anxiety, confusion from unstandardized protocols, doubts about PPE quality and effectiveness, and complexity of using...

Early auditory experience shapes the auditory spatial tuning of neurons in the barn owl's optic tectum in a frequency-dependent manner. We examined the basis for this adaptive plasticity in terms of changes in tuning for frequency-specific interaural time differences (ITDs) and level differences (ILDs), the dominant sound localization cues. We characterized broadband and narrowband ITD and ILD ...

Wireless earbuds have become the preferred electronic device for listening to music and hands-free talking. The combined radio performance of earbud handset determines quality established communication link hence user experience. This paper presents an extensive comparative study five common Bluetooth earbuds, where transmit performance, in terms total radiated power (TRP), is investigated. mea...

The occlusion effect is commonly experienced by in-ear device wearers as an increased loudness sensation of bone-conducted low frequency sounds. A widespread theory proposed Tonndorf and based on a simplified electro-acoustic model describes the phenomenon removal open earcanal high-pass filter due to perfect or partial occlusion. However, this has not been clearly defined several ambiguities r...
