Accelerator Test Facility at Brookhaven National Laboratory (BNL ATF) operates with 5 MeV photocathode gun and 70 MeV linac for different range of experiments with a few picoseconds and a few micrometers emittance electron bunch. Many conducted experiments require beam with good spatial resolution and short length as well. NdYaG laser pulse turns to the electron bunch in the gun with space char...

The real time implementation algorithms always include nested loops which require important execution times. Thus, several nested loop parallelism techniques have been proposed with the aim of decreasing their execution times. These techniques can be classified in terms of granularity, which are the iteration level parallelism and the instruction level parallelism. In the case of the instructio...

Nested loops are one of the most time-consuming parts and the largest sources of parallelism in many scientific applications. In this paper, we address the problem of 3-dimensional tiling and scheduling of three-level perfectly nested loops with dependencies on heterogeneous systems. To exploit the parallelism, we tile and schedule nested loops with dependencies by awareness of computational po...

Likelihood ratio tests (LRTs) for comparing models of sequence evolution have become popular over the last few years (Goldman 1993; Yang, Goldman and Friday 1994, 1995; Huelsenbeck and Crandall 1997; Huelsenbeck and Rannala 1997). In their simplest form, such tests compare a simpler null hypothesis (H0) with a more complex alternative hypotheses (H1) which is a generalization of H0. H0 can be d...

BACKGROUND Parasitological methods for the diagnosis of Visceral leishmaniasis (VL) require invasive procedures, so serological and molecular approaches have been developed but are not generally applicable in the field. We evaluated a loop mediated isothermal amplification (LAMP) assay using blood from VL patients and compared it to nested PCR. METHODS Forty-seven subjects with clinical featu...

Abst rac t . This paper defines the notion of hybrid atomicityfor nested transaction systems, and presents and verifies an algorithm providing this property. Hybrid atomicity is a modular property; it allows the correctness of a system to be deduced from the fact that each object is implemented to have the property. It allows more concurrency than dynamic atomicity, by assigning timestamps to t...

The research community has considered hash-based parallel join algorithms the algorithms of choice for almost a decade. However, almost none of the commercial parallel database systems use hashing-based join algorithms, using instead nested-loops with index or sort-merge. While the research literature abounds with comparisons between the various hash-based and sort-merge join algorithms, to our...

A large influx of experimental data has prompted the development of innovative computational techniques for modeling and reverse engineering biological networks. While finite dynamical systems, in particular Boolean networks, have gained attention as relevant models of network dynamics, not all Boolean functions reflect the behaviors of real biological systems. In this work, we focus on two cla...

Background: Zoonotic cutaneous leishmaniasis (ZCL) due to Leishmania major is increasing in many parts of Iran. This disease originally is a disease found in gerbils. Leishmania parasites are transmitted by sandflies that live and breed in gerbil burrows. Nested PCR amplified Leishmania ITS1-5.8S rRNA gene in both main reservoir host “Rhombomys opimus” and in the “Phlebotomus papatasi” main vec...

in this paper, we investigate the l-fuzzy proximities and the relationships betweenl-fuzzy topologies, l-fuzzy topogenous order and l-fuzzy uniformity. first, we show that the category of-fuzzy topological spaces can be embedded in the category of l-fuzzy quasi-proximity spaces as a coreective full subcategory. second, we show that the category of l -fuzzy proximity spaces is isomorphic to the ...
