Syphilis diagnosis is based on clinical observation, serological analysis, and dark-field microscopy (DFM) detection of Treponema pallidum subsp. pallidum, the etiological agent of syphilis, in skin ulcers. We performed a nested PCR (nPCR) assay specifically amplifying the tpp47 gene of T. pallidum from swab and blood specimens. We studied a cohort of 294 patients with suspected syphilis and 35...

BACKGROUND This work evaluated the hypothesis that 3,4-methylenedioxybenzoyl-2-thienylhydrazone (LASSBio-294), an agonist of adenosine A2A receptor, could be beneficial for preventing cardiac dysfunction due to hypertension associated with myocardial infarction (MI). METHODS Male spontaneously hypertensive rats (SHR) were randomly divided into four groups (six animals per group): sham-operati...

The author investigated the conditions under which a congruent or incongruent orientation word affects processing of the orientation of visual objects. Participants named the orientation of a rectangle that partially occluded another rectangle. Congruent or incongruent orientation words appeared in the relevant object, in the irrelevant object, or in the background. There were two main results....

Secchi depth has been measured in Lake Tahoe an average of every 12 d since July 1967. Because of the unusual clarity of the lake, Secchi depth measurement is responsive to small changes in light-attenuating particles, and the record exhibits strong variability at the seasonal, interannual, and decadal scales. Using recently developed methods of applied time-series analysis, the mechanisms of c...

Seven agricultural wastes named wheat bran (WB), rice straw (RS), wheat straw (WS), corn cob (CC), sugarcane bagasse (SCB), potato peal (PP) and banana peal (BP) were used for isolation of bacterial strains and as substrate for cellulases (CMCase, FPase and avicelase) and xylanase production. Five of the isolated strains were thermophilic and alkaliphilic. These bacterial isolates were tested t...

Text classification has increasing potential applications in many aspects of information world, such as recommender systems and customer service. The goal of this assignment is to apply Naive Bayes classifier to a data set of labeled textual movie reviews and practice Scala/ScalaNLP. The data set “Polarity dataset v2.0” is from http://www.cs.cornell.edu/People/pabo/movie-reviewdata/, created by...

An important aspect of data mining algorithms and systems is that they should scale well to large databases A consequence of this is that most data mining tools are based on machine learning algorithms that work on data in attribute-value format. Experience has proven that such ’single-table’ mining algorithms indeed scale well. The downside of this format is, however, that more complex pattern...

1. Max-Cut – problem definiton: Given an undirected graph G = (V,E), find a partition of the vertex set V = S ∪ S̄ that maximizes the number of cut-edges (edges with an endpoint in S and an endpoint in S̄). Examples: A clique, a bipartite graph, an odd cycle. The problem is NP-hard [7]. Can be approximated within factor 1/2 [11]. Exercise 1: Show that local search (iteratively move to the other s...
