Problem statement: Epilepsy is a common neurological disorder that afflicts 1-2% of the general population worldwide. It encompasses a variety of disorders with seizures. Approach: Idiopathic epilepsies were defined as a heterogeneous group of seizure disorders that show no underlying cause .Voltage-gated ion channels defect were recognized etiology of epilepsy in the central nervous system. Th...

To compare gender-related normal limits for left ventricular (LV) ejection fraction (EF), end-diastolic and end-systolic volumes (EDV and ESV), obtained using two myocardial perfusion-gated single photon emission computed tomography (SPECT) quantification methods. A total of 185 patients were retrospectively selected from a consecutive series of patients examined for coronary artery disease (CA...

In this study, the effect of dual gating on electrical characteristics amorphous indium-tin-gallium-zinc-oxide (a-ITGZO) thin-film transistors (TFTs) is investigated. The composition (In:Sn:Ga:Zn = 1.4:0.2:2.0:1.0 at.) a-ITGZO channel layer sputtered at 20°C close to that 1.6:0.2:2.0:1.0 ceramic target. a dual-gated TFT are superior those top- and bottom-gated TFTs. This dual-gating analyzed wi...

We study the queue length performance in non-exhaustive asymmetric polling systems with Bernoulli feedback. We obtain the PGF (Probability Generating Functions) and the mean values of the queue lengths, For the gated polling model, we define two new service policies: departure-gated policy and service-gated policy, and we demonstrate their difference in queueing performance. In an asymmetric sy...

The paper reports development of an FPGA-based control for a range-gated imaging system where real-time image and video processing is desired. The imaging system uses a pulsed laser for illumination and a gated camera for capturing images at desired distances. We demonstrate that FPGA can control the most important functions of the system, i.e. timing and synchronization of gating. In addition,...

We consider classes of graphs that enjoy the following properties: they are closed for gated subgraphs, gated amalgamation and Cartesian products, and for any gated subgraph the inverse of the gate function maps vertices to gated subsets. We prove that any graph of such a class contains a peripheral subgraph which is a Cartesian product of two graphs: a gated subgraph of the graph and a prime g...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...

OBJECTIVES We assessed the ability of anti-cyclic citrullinated peptide (CCP) tests to diagnose rheumatoid arthritis (RA), comparing the effect of manufacturer assay type, study design (single- and two-gated) and duration of disease (early vs. established). METHODS We searched seven databases for relevant diagnostic studies containing data on CCP tests in known or suspected RA patients. We us...

In this study, we have characterized the efficiency of an Elekta linac in the delivery of gated radiotherapy. We have explored techniques to reduce the beam-on delay and to improve the delivery efficiency, and have investigated the impact of frequent beam interruptions on the dosimetric accuracy of gated deliveries. A newly available gating interface was installed on an Elekta Synergy. Gating s...

Voltage-gated Na(+) channels play important functional roles in the generation of electrical excitability in most vertebrate and invertebrate species. These channels are members of a superfamily that includes voltage-gated K(+), voltage-gated Ca(2+) and cyclic-nucleotide-gated channels. There are nine genes encoding voltage-gated Na(+) channels in mammals, with a tenth homologous gene that has ...
