background: this study was conducted to detect clusters of pulmonary tb cases in hamadan province, west of iran. methods: all patients with pulmonary tuberculosis recorded in the surveillance system from 2005 to 2013 were studied. the spatial scan statistic was used to detect significant clusters in status of unadjusted and adjusted for age, sex and location residence variables. results: cluste...

We investigate structural properties of large, sparse random graphs through the lens sampling convergence (Borgs et al. (Ann. Probab. 47 (2019) 2754–2800). Sampling generalizes left to graphs, and describes limit in terms a graphex. introduce notion for sequences multigraphs, establish graphex configuration model, preferential attachment generalized graph bipartite variant model. The results mo...

Biliary excretion of cadmium was studied in two groups of five rats which were given repeated injections of 109Cd. The first group was given a total amount of 6 mg Cd/kg which was 6 times as much as the second group. The elimination of cadmium in bile, urine, and feces was measured 4 to 5 weeks after the last injection. The relative biliary excretion of cadmium was the same in both groupetion, ...

A bstract We develop an analytic approach to the four-point crossing equation in CFT, for general spacetime dimension. In a unitary (for, say, s - and t -channel expansions) can be thought of as vector infinite-dimensional space complex functions two variables, which satisfy boundedness condition at infinity. identify useful basis this functions, consisting set s- t-channel conformal blocks dou...

Clusters are geographically close groups of related companies or institutions related to a certain area which are inherently more efficient than the other companies due to advantages such as being located in one place, networks, external knowledge, variability of human capital, etc. Today, development through clusters plays a pivotal role in the economic and industrial policies of developed...

In a recent paper, for “large” (but otherwise unspecified) subsets A,B, C,D of Fq, Gyarmati and Sárközy (2008) showed the solvability of the equations a + b = cd, and ab + 1 = cd with a ∈ A, b ∈ B, c ∈ C, d ∈ D. They asked whether one can extend these results to every k ∈ N in the following way: for large subsets A,B, C,D of Fq, there are a1, . . . , ak, a1, . . . , ak ∈ A, b1, . . . , bk, b1, ...

DFT and QTAIM computations have been performed on numbers of pure nitrogen cluster speciesi.e. Nn (n = 4, 6) for investigating the structure and bonding. This study is critical since thesemolecules have been nominated as the good synthetic targets of High Energy Materials (HEM).0nthe other hand the decomposition mechanism is closely depends on the bonding pattern. Thislatter concept was searche...
