OBJECTIVE It has been shown that discharge of single darkness detector in the frog retina can lead to suprathreshold excitation of the tectal neurons. The present study was designed to explore whether a suprathreshold excitation of frog tectal neurons can be elicited by the discharge of single moving-edge detector. MATERIAL AND METHODS The discharge of a single retina ganglion cell was elicit...

This paper describes the theoretical foundation and prototype implementation of a transient event detector for use in a nonintrusive load monitor (NILM). The NILM determines the operating schedule of the major electrical loads in a building from measurements made at the electric utility service entry. The transient event detector extends the applicability of the NILM to challenging commercial a...

This study proposes a bidirectional chemical sensor platform using ambipolar double-gate ion-sensitive field-effect transistors (ISFET) with microwave-assisted Ni-silicide Schottky-barrier (SB) source and drain (S/D) on fully depleted silicon-on-insulator (FDSOI) substrate. The SB S/D offer turn-on characteristics for both p- n-type channel operations. operations are characterized by high noise...

Electrical stimulation has been widely used to modulate and study the in vitro and in vivo functionality of the nervous system. Here, we characterized the effect of electrical stimulation on ASH neuron in Caenorhabditis elegans and employed it to probe the neuron's age dependent properties. We utilized an automated microfluidic-based platform and characterized the ASH neuronal activity in respo...

A research prototype CT scanner is currently under development in our lab. One of the key components in this project is the CT detector. This paper describes the design and performance evaluation of the modular CT detector unit for our proposed scanner. It consists of a Photodiode Array Assembly which captures irradiating X-ray photons and converts the energy into electrical current, and a mini...

We investigated the effects of anodal and cathodal electrical stimulation on wound healing. In a randomized controlled trial, we divided 42 male albino guinea pigs into two control (C1 and C2) and four experimental (E1-E4) groups. A 3 cm linear incision was made at the dorsal skin of all guinea pigs. A unidirectional pulse current of 300 to 600 microamperes, 80 pps, and 0.3 ms pulse duration wa...

in this study the effect of input parameters of the edm process (pulse on-time, duty cycle and tool polarity), on the material removal rate (mrr), tool wear ratio (twr) and maximum surface roughness (rmax) in the machining aisi h13 tool steel has been studied. this study shows that increasing the duty cycle in the two conditions of tool polarity, material removal rate and the maximum surface ro...

A magnetic nanoparticle in a vortex state is a promising candidate for the information storage. One bit of information corresponds to the upward or downward magnetization of the vortex core (vortex polarity). Generic properties of the vortex polarity switching are insensitive of the way how the vortex dynamics was excited: by an ac magnetic field, or by an electrical current. We study theoretic...

An active RC matched filter, particularly useful for phase-coherent, coded or uncoded, binary or non-binary communication channels, is described. One detector circuit performs the equivalent of two simultaneous cross-correlations, avoiding the need for electronic multipliers, reference wave generation and phase synchronization. For example, only I circuits are needed in a receiver that is requi...
