Data consistency in transactional federations is a key requirement of advanced E-service applications on the Internet, such as electronic auctions or real-estate purchase. Federated concurrency control needs to be aware of the fact that virtually all commercial database products support sub-serializability isolation levels, such as Snapshot Isolation, and that applications make indeed use of su...

For more than 25 years, honey has been employed to facilitate the healing of complex wounds with excellent results. Here, we report the case of a two-and-a-half-year-old agammaglobulinemia patient admitted in our unit for severe sepsis with extensive skin necrosis in the groin, penis and scrotum. An Ecthyma Gangrenosum was corroborated by the isolation of Pseudomonas aeruginosa in wound s...

Understanding how speciation can take place in the presence of homogenizing gene flow remains a major challenge in evolutionary biology. In the early stages of ecological speciation, reproductive isolation between populations occupying different habitats is expected to be concentrated around genes for local adaptation. These genomic regions will show high divergence while gene exchange in other...

The most recent Ebola outbreak in West Africa highlighted critical weaknesses in the medical infrastructure of the affected countries, including effective diagnostics tools, sufficient isolation wards, and enough medical personnel. Here, we develop and analyze a mathematical model to assess the impact of early diagnosis of pre-symptomatic individuals on the transmission dynamics of Ebola virus ...

In this letter, a dual-band Multiple Input Multiple Output (MIMO) antenna system with high isolation is presented. This design consists of two dual-band monopole antennas and neutralizing transmission line. For each antenna element, the operating frequency band covers from 2.4GHz to 2.6GHz and 5.2GHz to 6GHz. To improve the isolation between these two antenna elements spacing only 0.1225λ0 at 2...

BACKGROUND AND AIMS Among-population differentiation in phenotypic traits and allelic variation is expected as a consequence of isolation, drift, founder effects and local selection. Therefore, investigating molecular and quantitative genetic divergence is a pre-requisite for studies of local adaptation in response to selection under variable environmental conditions. METHODS Among- and withi...

The majority of evidence from in vivo studies indicates that theta rhythms are imposed upon cortical structures by projections from the medial septum/diagonal band. Anatomical studies have indicated highly specific target neuronal classes for one branch of this projection (that using GABA as a transmitter) but less specific target specificity for the other branch (that using acetylcholine). In ...

This paper presents a novel coupled-fed broadband dual-polarized magnetoelectric dipole antenna for wireless local area network (WLAN) and 5G communication applications. The proposed is composed of planar electric shorting pins as magnetic to obtain broad operation frequency band. Two coupled microstrip lines perpendicular each other are through cross-shaped slot excite the vertical horizontal ...

the rhizome of anemarrhena asphodeloides is used as food and traditional chinese medicine for its hypoglycemic effect. the aim of this study was to investigate the isolation, purification and hypoglycemic activity of anemaran as the active component. the influence factors (isolation duration, ratio of residuals to water and extracting times) during the isolation process were evaluated. the opti...

background: there are eight taxus species and two hybrids in the world and taxus baccata l. (european yew) is the single representative in iran. until now, a large number of taxoids possessing different skeleton systems, as well as lignans, flavonoids, steroids and sugar derivatives have been isolated from various taxus species. taxoids are highly oxygenated diterpenes isolated from different s...
