We study the problem of graph partitioning, or clustering, in sparse networks with prior information about the clusters. Specifically, we assume that for a fraction ρ of the nodes the true cluster assignments are known in advance. This can be understood as a semi–supervised version of clustering, in contrast to unsupervised clustering where the only available information is the graph structure....
Franklin William Stahl studied DNA replication, bacteriophages, and genetic recombination in the US during the mid-twentieth and early twenty-first centuries. With his colleague Matthew Meselson, Stahl performed an experiment called the Meselson-Stahl experiment, which provided evidence for a process called semi-conservative DNA replication. Semi-conservative replication is a process in which e...
Let A be a Banach algebra and X a Banach A-bimodule, the derivation D : A → X is semi-inner if there are ξ, μ ∈ X such that D(a) = a.ξ − μ.a, (a ∈ A). A is called semi-amenable if every derivation D : A → X∗ is semi-inner. The dual Banach algebra A is Connes semi-amenable (resp. approximately semi-amenable) if, every D ∈ Z1w _ (A,X), for each normal, dual Banach A-bimodule X, is semi -inner (re...
زمینه مطالعه: تیلریوز یکی از بیماریهای تک یاخته ای خونی در گاو بوده که سبب مرگ و میر بالا می شود. تاکنون مطالعات میکروسکوپی زیادی درباره شناسایی گونه های آلوده کننده تیلریا در گاو و کنه های ناقل صورت گرفته که در مقایسه با روش های مولکولی از حساسیت و ویژگی کمی برخوردارند. هدف: دراین مطالعه سعی شدگونه های تیلریاوناقلین آن درگاوهای شهرستان یزدباروشsemi-nested pcr موردشناسایی قرارگیرند. مواد و روش ...
secreted cytokines of th1 (t-helper)/th2 cells play an important role in the pathogenesis of many diseases. th1 cells secrete predominantly ifn-γ and il-2 which regulate cell-mediated immunity against intracellular pathogens and tumors. in this study, expression of ifn-γ was studied using semiquantitative rt-pcr. in brief, lymphocytes of a healthy donor were stimulated with pha (1μg/106 cell/ml...
conclusions in this study, snpcr was specific and more sensitive than the chromogenic medium chromagar™ candida for the detection of candida spp. insofar as it failed to identify only a few isolates. materials and methods we used snpcr with universal and species-specific primers to detect candida species in the culture of clinical isolates. by using universal primers, we carried out the amplifi...
metric (mapping evapotranspiration at high resolution with internalized calibration) is known as an appropriate surface energy balance model for the estimation of the spatial distribution of evapotranspiration (et) in semi-arid regions. based on lysimeter measurements, metric has shown et estimates of 10% on a sub-field scale on a daily basis. there is a need to identify how the model is sensit...
