The Web of Linked Data forms a single, globally distributed Web. Querying this dataspace poses new challenges that are not addressed by traditional research on federated query processing. Linked data integration applications must meet the requirements of efficient query processing in the distributed setting. This paper presents QEF-LD, a query engine that enables the efficient execution of fede...

EDN-LD is a set of conventions for representing linked data using Extensible Data Notation (EDN) and a library for conveniently working with those representations in the Clojure programming language. It provides a lightweight alternative to existing linked data tools for many common use cases, much in the spirit of JSON-LD. We present the motivation and design of EDN-LD, and demonstrate how it ...

The hitchhiking effect of a beneficial mutation, or a selective sweep, generates a unique distribution of allele frequencies and spatial distribution of polymorphic sites. A composite-likelihood test was previously designed to detect these signatures of a selective sweep, solely on the basis of the spatial distribution and marginal allele frequencies of polymorphisms. As an excess of linkage di...

PURPOSE To evaluate image quality and signal characteristics of brain perfusion CT (BPCT) obtained by low-dose (LD) and ultra-low-dose (ULD) protocols with and without post-processing by highly constrained back-projection (HYPR)-local reconstruction (LR) technique. METHODS AND MATERIALS Simultaneous BPCTs were acquired in 8 patients on a dual-source-CT by applying LD (80 kV, 200 mAs, 14×1.2 m...

BACKGROUND The current method for a non-invasive assessment of diastolic dysfunction is complex with the use of algorithms of many different echocardiographic parameters. Total average diastolic longitudinal displacement (LD), determined by colour tissue Doppler imaging (TDI) via the measurement of LD during early diastole and atrial contraction, can potentially be used as a simple and reliable...

background: one of the biggest problem today that most developing countries are faced with is the uncontrolled population growth; a serious threat to the international community. one of the most accessible contraceptive methods is the hormonal methods in which low-dose estrogen (ld) combined pills are considered as the most common among them. the most important reason for discontinuation of the...

Science and engineering research increasingly relies on activities that facilitate research but are not currently rewarded or recognized, such as: data sharing; developing common data resources, software and methodologies; and annotating data and publications. To promote and advance these activities, we must develop mechanisms for assigning credit, facilitate the appropriate attribution of rese...

In linkage and linkage disequilibrium (LD) analysis of complex multifactorial phenotypes, various types of errors can greatly reduce the chance of successful gene localization. The power of such studies-even in the absence of errors-is quite low, and, accordingly, their robustness to errors can be poor, especially in multipoint analysis. For this reason, it is important to deal with the ramific...
