We report on implementation and a modest experimental evaluation of a recently introduced priority queue data structure The new data structure is designed to take advantage of fast operations on machine words and as appropriate reduced key universe size and or tolerance of approximate answers to queries In addition to standard priority queue operations the data structure also supports successor...

The perspective of competition in the high technology industry has changed impressively over the last two decades and the indicators which can be defined as the traditional indicators of business performance are insufficient today. So we have identified a new set of financial and non-financial performance indicators that can be used by firms and then, we developed a business performance measure...

BACKGROUND Despite apparently abundant amounts of observable variation and species diversity, the order Lepidoptera exhibits a morphological homogeneity that has provided only a limited number of taxonomic characters and led to widespread use of nucleotides for inferring relationships. This study aims to characterize and develop methods to quantify the value of priority gene regions designated ...

OBJECTIVE To investigate the role of serial measurement of urine neopterin concentration in monitoring the progression of systemic lupus erythematosus (SLE) disease activity scored using the British Isles Lupus Assessment Group (BILAG) index. METHODS We followed prospectively 68 unselected SLE patients for a total of 464 patient months during which 233 separate assessments were carried out. A...

UNLABELLED Up to 3 million US children are cared for by emergency medical services (EMSs) annually. Limited research exists on pediatric prehospital care. The Pediatric Emergency Care Applied Research Network (PECARN) mission is to perform high-quality research for children, including prehospital research. Our objective was to develop a pediatric-specific prehospital research agenda. METHODS ...

This paper focuses on the instruction fetch resources in a real-time SMT processor to provide an energy-efficient configuration for a soft real-time application running as a high priority thread as fast as possible while still offering decent progress in low priority or non-realtime thread(s). We propose a fetch mechanism, Fetch-around, where a high priority thread accesses the L1 ICache, and l...

OBJECTIVE To describe the prospective relationship between physical activity and academic performance. DATA SOURCES Prospective studies were identified from searches in PubMed, PsycINFO, Cochrane Central, and Sportdiscus from 1990 through 2010. STUDY SELECTION We screened the titles and abstracts for eligibility, rated the methodological quality of the studies, and extracted data. MAIN EX...
