BACKGROUND The issue of how differences in timbre are represented in the neural response still has not been well addressed, particularly with regard to the relevant brain mechanisms. Here we employ phasing and clipping of tones to produce auditory stimuli differing to describe the multidimensional nature of timbre. We investigated the auditory response and sensory gating as well, using by magne...

This study develops the preprocessing theory for time-reversal multiple signal classification (TR-MUSIC) imaging from the one-dimensional (time-domain) gating proposed in earlier papers to a two-dimensional one. Although the one-dimensional gating technique for TR-MUSIC mitigates the effect of noise as well as reduces the required number of antenna elements, the resulting image is subject to fo...

The influence of long and short polymer chains on the gating properties of nanochannel systems modified with a NIPAAm-co-PBA copolymer have been explored. We not only discovered the negative temperature gating behavior of the NIPAAm modified nanochannel systems for the first time, but also achieve these two fully opposite gating behaviors (negative/positive) on the same platform.

Voltage-gated sodium channels mediate the initiation and propagation of action potentials in excitable cells. Transmembrane segment S4 of voltage-gated sodium channels resides in a gating pore where it senses the membrane potential and controls channel gating. Substitution of individual S4 arginine gating charges (R1-R3) with smaller amino acids allows ionic currents to flow through the mutant ...

A current noise reduction technique in chopper instrumentation amplifier (CIA) for high-impedance sensor is presented. The proposed technique is based on a time gating method to reduce time varying shot noise which is induced by channel charge injection of chopper switch transistors. An implemented CIA with the proposed time gating technique achieves more than 80-% noise reduction capability.

A time-reversal (TR) approach with multiple signal classification (MUSIC) provides super-resolution for detection and localization using multistatic data collected from an array antenna system. The theory of TR-MUSIC assumes that the number of antenna elements is greater than that of scatterers (targets). Furthermore, it requires many sets of frequencydomain data (snapshots) in seriously noisy ...
