this research presents a numerical tool to estimate the green's function operator matrix of intraplate faults. having this matrix and its inverse, spatial distribution of fault slippage could be investigated through the inverse analysis of geodetic data. this information could be employed to predict the location of future powerful earthquakes. to implement fault sliding in fe calculations,...

It is necessary to generate the automorphism group of a chemical graph in computer-aided structure elucidation. An Euclidean graph associated with a molecule is defined by a weighted graph with adjacency matrix M = [dij], where for i≠j, dij is the Euclidean distance between the nuclei i and j. In this matrix dii can be taken as zero if all the nuclei are equivalent. Otherwise, one may introduce...

In this paper we study the potential of simple linear gene-protein interaction networks to store sparse input-output patterns. This problem bears similarity to the engineering task of reconstructing gene networks from time series of expression data, such as sets of microarrays. This is currently an intensively studied field where some results are directly applicable to our context. The central ...

background: there is a growing concern on the impact of the presence of extended-spectrum β-lactamase (esbl) producing escherichia coli isolated from animals on public health. objectives: the aim of this study was to investigate the presence of three classes of esbl genes in e. coli isolates from sheep and broilers at a slaughter in urmia region, iran. methods: a total of 111 e. coli isolates w...

A real-time reverse-transcription PCR (RRT-PCR) was developed to detect avian paramyxovirus 1 (APMV-1) RNA, also referred to as Newcastle disease virus (NDV), in clinical samples from birds. The assay uses a single-tube protocol with fluorogenic hydrolysis probes. Oligonucleotide primers and probes were designed to detect sequences from a conserved region of the matrix protein (M) gene that rec...

background the association between tumor necrosis factor-alpha (tnf-α) (-308 g/a) gene polymorphisms and level of tissue destruction and periodontal disease progression is not proved. objectives the present study investigated the stereological parameters of interdental papilla in chronic periodontitis (cp) patients with tnf-α (-308 g/a) gene polymorphisms. materials and methods sixty gingiva sa...

conclusions this study demonstrated the specificity and sensitivity of the pcr-sscp method for finding mutations in the gyra gene. due to the sensitivity of most isolates to ciprofloxacin, this antibiotic should be considered an appropriate drug for the treatment of related diseases. background during the past several years, nontuberculous mycobacteria (ntm) have been reported as some of the mo...
