in this paper, chebyshev acceleration technique is used to solve the fuzzy linear system (fls). this method is discussed in details and followed by summary of some other acceleration techniques. moreover, we show that in some situations that the methods such as jacobi, gauss-sidel, sor and conjugate gradient is divergent, our proposed method is applicable and the acquired results are illustrate...

COVID-19 pandemic-related pressures on primary care may have driven the inappropriate continuation of antibiotic prescriptions. Yet, prescribing modality (repeat/non-repeat) has not previously been investigated in a pandemic context. With approval NHS England, we conducted retrospective cohort study >19 million English patient records using OpenSAFELY-TPP analytics platform. We analysed repe...

Objective(s) Varicocele is associated with impaired testicular function and male infertility, but the molecular mechanisms by which fertility is affected have not been satisfactorily explained. The aim of our study was to investigate whether or not the polymerase gamma (POLG) polymorphism is associated with Iranian varicocele patients.    Materials and Methods We determined the POLG CAG repe...

Herpes simplex virus 1 (HSV-1) unspliced 8.3 latency associated transcript (LAT), which located in the long repeat sequences, has been shown to contain at least 16 open reading frames (ORF: A-P). One of these ORF, ORF P, maps almost entirely antisense to HSV-1 neurovirulence gene, ICP34.5. Both ORF P and ICP34.5 are located in the long repeat and are antisense overlapping genes. Therefore, in O...

SUMMARY The effect of antibiotic prophylaxis in repeat cesarean section were studied in a prospective, double blind clinical trial. 102 pregnant patients with history of previous cesarean section were studied. The partients entered in two groups; A & B: group A were given 2gr cephalosporin and group B 2gr placebo for 3 dose (IV). From 102 patients 48 pt were in group A and 54 were in group B. ...

Castor (Ricinus communis L.) is one of the most ancient medicinal oil crops in the world. It has been vastly distributed in different parts of Iran. In the present study, the inter simple sequence repeat (ISSR) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of Iran. Totally, 16 ISSR primers amplified 166 loci...

Sequence tagged microsatellite profiling (STMP) enables the rapid development of large numbers of co-dominant DNA markers, known as sequence tagged microsatellites (STMs). Each STM is amplified by PCR using a single primer specific to the conserved DNA sequence flanking the microsatellite repeat in combination with a universal primer that anchors to the 5'-ends of the microsatellites. It is als...

Paravalvular leak (PVL) occurs in up to 12.5% of mitral valve replacements (MVRs) and sometimes recurs. Although various techniques to repair such leaks have been described, surgical intervention for patients undergoing multiple repeat surgery poses a formidable challenge. For the purposes of good exposure and durable repair of mitral PVL, we describe a double closure technique with pledgeted s...

In transactional memory, conflicts between two concurrently executing transactions reduce performance, reduce scalability, and may lead to aborts, which waste computing resources. Ideally, concurrent execution of transactions would be ordered to minimise conflicts, but such an ordering is often complex, or unfeasible, to obtain. This paper identifies a pattern, called repeat conflicts, that can...
