Twenty experienced binaural hearing aid users evaluated a two-channel behind-the-ear instrument, with a low band that offered dynamic range compression and a high band that provided linear amplification. After a 5-week trial period, data from the Profile of Hearing Aid Performance (PHAP), the Speech Perception in Noise (SPIN) test, as well as 2-cm3 coupler measurements were compared for the two...
A receiver transforms correlated channel state information (CSI) to an uncorrelated sparse CSI vector by using a principal component analysis (PCA), and feeds it back to a transmitter. The PCA extracts essential information from the CSI without redundancy that arises from the highly correlated antennas. The transmitter then recovers the original CSI through the inverse transformation of the fee...
Voltage gated sodium channels (Nav channels) play an important role in nociceptive transmission. They are intimately tied to the genesis and transmission of neuronal firing. Five different isoforms (Nav1.3, Nav1.6, Nav1.7, Nav1.8, and Nav1.9) have been linked to nociceptive responses. A change in the biophysical properties of these channels or in their expression levels occurs in different path...
BACKGROUND Experiments in isolated perfused heart have shown that heart rate is lower and sinoatrial node (SAN) action potential duration is longer in streptozotocin (STZ)-induced diabetic rat compared to controls. In sino-atrial preparations the pacemaker cycle length and sino-atrial conduction time are prolonged in STZ heart. To further clarify the molecular basis of electrical disturbances i...
We study experimentally the flow of a foam confined as a bubble monolayer between two plates through a convergent channel. We quantify the velocity, the distribution and orientation of plastic events, and the elastic stress, using image analysis. We use two different soap solutions: a sodium dodecyl sulfate (SDS) solution, with a negligible wall friction between the bubbles and the confining pl...
