Introduction: Effective out-of-hospital administration of naloxone in opioid overdoses is dependent on timely arrival naloxone. Delays emergency medical services (EMS) response time could potentially be overcome with drones to deliver efficiently the scene for bystander use. Our objective was evaluate a mathematical optimization simulation geographical placement drone bases reducing overdose.Met...

In this paper we investigate a new notion of bases in Hilbert spaces and similar to fusion frame theory we introduce fusion bases theory in Hilbert spaces. We also introduce a new denition of fusion dual sequence associated with a fusion basis and show that the operators of a fusion dual sequence are continuous projections. Next we dene the fusion biorthogonal sequence, Bessel fusion basis, Hil...

the issues that arise in this articles are the causes and the bases of social - and sexual - devience according to a sociological point of view. then a search through a number of 350 files of sexual - crimes in babol, declares the causes on a sociological point of view, cultural transmission & contrast theory. in assessment during this research regarding age, sex & occupation as the main criter...

Ecological specialization is hypothesized to result from the exploitation of predictable resource bases. For parasitic organisms, one prediction is that parasites of large-bodied host species, which tend to be long-lived, should specialize on these hosts, whereas parasites of small host species, which represent more ephemeral and less predictable resources, should become generalists. We tested ...

Objectives. International guidelines differ in the threshold of tuberculin skin test (TST) induration regarded as indicating Mycobacterium (M.) tuberculosis infection. Interferon gamma release assay (IGRA) results were used as reference to assess performance of TST induration thresholds for detection of M. tuberculosis infection in children. Design. Systematic review which included studies cont...

World-wide collaboration in high-energy physics (HEP) is a tradition which dates back several decades, with scientific publications mostly coauthored by scientists from different countries. This coauthorship phenomenon makes it difficult to identify precisely the “share” of each country in HEP scientific production. One year’s worth of HEP scientific articles published in peer-reviewed journals...

Inferring the historical context of ecological diversification is an important step in understanding the way that population-level processes result in a diversity of species and interactions in communities. We performed a phylogeographic analysis of mitochondrial DNA haplotypes from the pollinating seed parasite Greya politella (Lepidoptera: Prodoxidae) in order to determine the degree to which...

Located at the cross-road between Europe and Africa, Tunisia is a North African country of 11 million inhabitants. Throughout its history, it has been invaded by different ethnic groups. These historical events, and consanguinity, have impacted on the spectrum and frequency of genetic diseases in Tunisia. Investigations of Tunisian families have significantly contributed to elucidation of the g...

The potential of the Internet to both geographically expand customer bases and provide a source of sales growth has led to a rapid embracement of the Internet by a majority of small businesses in the United Kingdom. However, many studies suggest that much of this adoption takes the form of simple Web sites representing little more than an electronic brochure. Although theories and models have b...

Database watermarking techniques allow for hiding in-formation in a database, like a copyright mark. Whilewatermarking methods are numerous in the multi-media setting, databases present various specificities.This work addresses some of them: how to watermarka numerical database while preserving the result of in-teresting aggregate queries, how to watermark a struc-tu...
