Background: Brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. Serum agglutination test (SAT) is the most-widely used test for diagnosing brucellosis. The enzyme linked immunosorbent assay (ELISA) can also determine specific antibody classes against brucella. It is a sensitive, simple and rapid test, which coul...

An interesting strategy called configuration checking (CC) was recently proposed to handle the cycling problem in local search for Minimum Vertex Cover. A natural question is whether this CC also works SAT. The direct application of did not result stochastic (SLS) algorithms that can compete with current best SLS In paper, we propose a new heuristic based on SAT, which aspiration (CCA). It used...

SAT has become the backbone of many software systems. In order to make full use of the power of SAT solvers, a SAT compiler must encode domain variables and constraints into an efficient SAT formula. Despite many proposals for SAT encodings, there are few working SAT compilers. This paper presents Picat-SAT, the SAT compiler in the Picat system. Picat-SAT employs the sign-and-magnitude log enco...

Last year when UC President Atkinson proposed discontinuing UC's use of the SAT I examination as an admissions requirement in favor of the SAT II, UCOP released several papers describing a series of studies assessing the relative predictive validity of SAT I and SAT II test scores and high school GPA on UC freshman GPA. The mediating effect of socioeconomic status (SES) was also considered. The...

classifying remote sensing imageries to obtain reliable and accurate landuse/cover (luc) information still remains a challenge that depends on many factors suchas complexity of landscape especially in arid region. the aim of this paper is to extractreliable luc information from land sat imageries of the pishkouh watershed of centralarid region, iran. the classical maximum likelihood classifier ...

Soybean Mosaic Virus (SMV) is one of the most important soybean diseases in world, and it seriously affects yield quality. In this paper, 405 SSR molecular markers were used genome-wide scan to analysis 327 varieties North China. The purpose was search genetic loci excellent resistance genes related SMV1 SMV3, reveal differences between models varieties. results confirmed that among tested larg...

We study a special class of binary trees. Our results have implications on Maker/Breaker games and SAT: We disprove a conjecture of Beck on positional games and construct an unsatisfiable k-CNF formula with few occurrences per variable, thereby improving a previous result by Hoory and Szeider and showing that the bound obtained from the Lovász Local Lemma is tight up to a constant factor. A (k,...

Water is a limiting factor for economic and social development in most arid semi-arid regions on Earth. The deliberate recharge of depleted aquifer storage later recovery, known as managed (MAR), an important tool water management sustainability . Increasing stresses groundwater subsequent overdrafts have sparked the several advanced MAR technologies, including soil treatment (SAT). SAT method ...

The pLE2SCX vector was developed for the stable expression of exogenous genes in the protozoan parasite Leishmania. The pLE2SCX construct contains three independent selection markers: herpes simplex virus thymidine kinase (HSV-TK), cytosine deaminase (CD) and streptothericin acetyltransferase gene (sat) in multiple cloning site, flanking by 5’ and 3’ untranslated regions of the previously clone...

I discuss recent progress in developing and exploiting connections between SAT algorithms and circuit lower bounds. The centrepiece of the article is Williams’ proof that NEXP 6⊆ ACC, which proceeds via a new algorithm for ACC-SAT beating brute-force search. His result exploits a formal connection from non-trivial SAT algorithms to circuit lower bounds. I also discuss various connections in the...
