Conductive ceramics like cobalt bonded tungsten carbide which is categorized as with high mechanical and physical properties are usually known to create major challenges during conventional and non-conventional machining. Electrical discharge machining (EDM) which is very prominent amongst the non-conventional machining methods is expected to be used quite extensively in machining it due to the...

The glomerular sheet of the olfactory bulb (OB) forms odorant receptor maps that are parceled into zones. We previously reported the molecular receptive range (MRR) property of individual glomeruli in the dorsal zone (zone 1) of the OB and showed that polar functional groups play a major role in activating glomeruli in this zone. However, the MRR property of glomeruli in zones 2-4 is not well u...

Hummingbird participated in the named page finding task of the TREC 2002 Web Track (find the named page in 18GB from the .GOV domain) and the monolingual Arabic topic relevance task of the TREC 2002 Cross-Language Track (find all relevant documents in 869MB of Arabic news data).

A grating-based Fabry-Perot (FP) cavity-coupled microring resonator on a silicon chip is reported to demonstrate an all-optically tunable Fano resonance. In the device, an add-drop microring resonator (MRR) is employed, and one of the two bus waveguides is replaced by an FP cavity consisting of two sidewall Bragg gratings. By choosing the parameters of the gratings, the resonant mode of the FP ...

Electro-discharge machining (EDM) is increasingly being used in many industries for producing molds and dies, and machining complex shapes with material such as steel, cemented carbide, and engineering ceramics. The stochastic nature of EDM process has frustrated number of attempts to model it physically. Artificial neural networks (ANNs), as one of the most attractive branches in Artificial In...

Query auto completion is known to provide poor predictions of the user’s query when her input prefix is very short (e.g., one or two characters). In this paper we show that context, such as the user’s recent queries, can be used to improve the prediction quality considerably even for such short prefixes. We propose a context-sensitive query auto completion algorithm, NearestCompletion, which ou...

SKD11 has been a widely used tool steel for cold works many years while DC53 is intently developed to replace SKD11. In this paper, the machinability of these two steels was compared in terms material removal rate (MRR), electrode wear ratio (EWR), and arithmetic mean value roughness (Ra) specimen machined by electric-discharge machining. The machining variables involved were time peak current....

Chronic Helicobacter pylori ( H. pylori) infection is a major gastric adenocarcinoma (GA) risk factor. GA disproportionately affects U.S. Hispanics compared with non-Hispanic Whites (NHWs). Since H. pylori infection studies in Hispanics are few, infection rates in Hispanic and NHW men in Bexar County were compared, and relationships with ethnicity and obesity examined. Age- and zip code-matched...

BACKGROUND AND PURPOSE The relationship between in-hospital stroke-related medical complications and clinical outcome remains unclear. We examined whether medical complications were associated with length of stay (LOS) and mortality among stroke unit patients. METHODS Using population-based Danish medical registries, we performed a follow-up study among all patients with acute stroke admitted...
