We describe an field-programmable gate arrays based (FPGA), 96-channel, Time-to-Digital converter (TDC) and trigger logic board intended for use with the Central Outer Tracker (COT) [T. Affolder et al., Nucl. Instr. and Meth. A 526 (2004) 249] in the CDF Experiment [The CDF-II detector is described in the CDF Technical Design Report (TDR), FERMILAB-Pub-96/390-E. The TDC described here is intend...

BACKGROUND The optimal therapy for preventing recurrent stroke in people with cryptogenic stroke and patent foramen ovale (PFO) has not been defined. The choice between medical therapy (antithrombotic treatment with antiplatelet agents or anticoagulants) and transcatheter device closure has been the subject of intense debate over the past several years. Despite the lack of scientific evidence, ...

BACKGROUND Dialysate-based, on-line measurements of Kt/V and protein catabolic rate (PCR) in dialysis patients have been considered more accurate compared with measurements on the blood side during dialysis. The primary aim of this study was to compare total removed urea (TRU) and PCR, normalized to body weight (nPCRw), obtained by three dialysate-based methods: (i) on-line ultraviolet (UV) abs...

A new learning scheme called time divergence-convergence – TDC – is proposed for two-layer dynamic synapse neural networks – DSNN. DSNN is an artificial neural network model, in which the synaptic transmission is modeled by a dynamic process and the information between neurons are transmitted through spike timing. In TDC, the intra-layer neurons of a DSNN are trained to map input spike trains t...

OBJECTIVE A less invasive method to assess internal thoracic artery (ITA) graft function after coronary artery bypass grafting (CABG) is desired. This study reports the novel method to estimate ITA graft function using CT angiography. MATERIALS AND METHODS Fifty ITA grafts were assessed. Hounsfield Unit transition of each graft on the same cross section was detected during the Test Bolus Inje...

Driving cycles are series of data points that represent vehicle speed versus time sequenced profile developed for specific road, route, city or certain location. It is widely utilized in the application manufacturers, environmentalists and traffic engineers. Since vehicles one higher air pollution sources, driving cycle needed to evaluate fuel consumption exhaust emissions. The main objectives ...

three types of vehicles, pride, peugeot 405 glx and paykan were tested from the point of view of exhaust emissions (co, hc, nox) and fuel consumption, on chassis dynamometer running european standard driving cycle with three kinds of fuels, mtbe free unleaded regular gasoline (urg) as base fuel and 10 and 15 volume percent mtbe –gasoline blends as comparable fuels. utilizing mtbe blended fuels ...

OBJECTIVE A long history of inconsistencies in the definitions of the outcome measures for chronic subdural hematomas (CSDHs) has contributed to the controversy over the optimal surgical strategy for CSDH treatment. Clarifying these definitions, reassess the available data, and systematically review the prior literature may provide better insight into the differences in treatment efficacy for C...
