The whisker-to-barrel system of adult mice was used in a study on the effects of short-lasting tactile stimulation and sensory conditioning training on GABAA receptor binding in the barrel field of somatosensory cortex. In vitro receptor binding autoradiography was used to examine the pattern and intensity of [3H]muscimol binding to GABAA receptors. A well-defined pattern of GABAA receptors in ...

Wenlin procedure is a special operation designed by us. In the early stage, it was specially used for treatment of pectus carinatum. Later, we found that also had an effect on other protrusion deformities. Barrel chest can be regarded as overall wall, so kind deformity. Because there protrusion, should play role. We this in barrel and obtained satisfactory results. Our experience shows ideal ch...

The CMS pixel barrel system will consist of three layers built of about 800 modules. One module contains 66560 readout channels and the full pixel barrel system about 48 million channels. It is mandatory to test each channel for functionality, noise level, trimming mechanism, and bump bonding quality. Different methods to determine the bump bonding yield with electrical measurements have been d...

The somatosensory neocortex processes extrinsic information from the thalamus and intrinsic information from local circuits. We compared the effects of acetylcholine (Ach) on neocortical field potential responses evoked by stimulation of the whiskers and by local electrical stimulation in the upper layers of the neocortex vibrissae representation ("barrel cortex") of adult rats anesthetized wit...


 Understanding the heat transfer phenomenon during interior ballistics and consequently presenting a realistic model is very important to predict temperature distribution inside cannon barrel, which influences gun wear cook-off. The objective of this work present new detailed numerical for prediction thermal behaviour barrel by combining PRODAS simulation with COMSOL simulation. In study,...

A variable phase shifter using a movable waffle iron metal plate comprised of iron rods a quarter-wavelength in length is proposed. A study of the waffle iron structure was carried out and the design method for creating a structure that would achieve large phase changes, small loss, and good isolation between adjacent phase shifters is discussed. Experiments on 1-port and 2-port phase shifters ...

Bright Minds, Big Rent: Gentrification and the Rising Returns to Skill* In 1980, housing prices in the main US cities rose with distance to the city center. By 2010, that relationship had reversed. We propose that this development can be traced to greater labor supply of high-income households through reduced tolerance for commuting. In a tractlevel data set covering the 27 largest US cities, y...

Barrel shifters are often required for performing data shifting and rotation in many key computer operations from address decoding to computer arithmetic. In this paper we present a comparative study of various parameters like delay, power and area, for a high performance 16-bit barrel shifter VLSI implementations using three different logic design styles (conventional CMOS, transmission gate C...

In this project, we use recent findings from electrophysiological recordings and a previous model of the cellular properties of barrel cortical neurons to explore their implications on the dynamic properties of directional tuning in barrel cortex. We find that directional tuning is influenced by the frequency and speed of whisker directions, even in the low frequency range of natural whisking. ...

Background Data: Peripheral nerve injuries (PNIs) by either gunshot missiles or shrapnel from barrel bomb explosions are common during war.
