Objective(s): Clostridioides (Clostridium) difficile infection as a healthcare-associated infection can cause life-threatening infectious diarrhea in hospitalized patients. The aim of this study was to investigate the toxin profiles and antimicrobial resistance patterns of C. difficile isolates obtained from hospitalized patients in Shiraz, Iran.Mater...

We present evidence that the spectroscopically identified bipolar jets of the pre-main sequence binary KH 15D (P=48.4 d, ǫ ∼0.6, periastron separation ∼18 RA, MA=0.6M⊙, MB=0.7M⊙) are a common product of the whole binary system, rather than being launched from either star individually. They may be launched from the innermost part of the circumbinary disk (CBD) or may result from the merging of t...

Gene expression data are usually redundant, and only a subset of them presents distinct profiles for different classes of samples. Thus, selecting high discriminative genes from gene expression data has become increasingly interesting in bioinformatics. In this paper, a multiobjective binary differential evolution method (MOBDE) is proposed to select a small subset of informative genes relevant...

FUSE spectra were obtained of the supersoft X-ray binary RX J0019.8+2156 (QR And) during 16 consecutive spacecraft orbits, covering the binary orbit (P=15.85 hr) with about 0.2 phase overlap. The spectrum is dominated by strong H 2 absorption (column density ∼10 20 g cm −2), which appears at the velocity different from other interstellar absorption lines and may be partially circumbinary. This ...

infinite dilution activity coefficients have been measured for seven binary systems at three different pressures using a newly - designed ebulliometer. the results obtained through these experimental measurements have been compared to literature values for four of the seven binary systems and the calculated deviation has been less than five percent in most cases. having verified the soundness a...

A new haiftoning method for color image is proposed. The proposed algorithm is very simple to implement the halftoning in hardware and software, which indexes the image pixel values to a binary database as proposed by Sullivan et a!. The database is a set of dot profiles representing the corresponding gray levels. The dot profiles are sequentially generated from a visual-optimized seed pattern ...

We present non-LTE calculations for an expanding red giant’s atmosphere ionized from the outside by the radiation of a nearby hot radiation source. We show that the hydrogen emission lines emerge from a narrow transition zone where hydrogen changes from ionized to neutral. In this region the Balmer lines are optically thick, and their profiles crucially depend on the magnitude of optical thickn...

Due to the diverse medicinal effects, polyphenols are among the most intensively studied natural products. However, it is a great challenge to elucidate the polypharmacological mechanisms of polyphenols. To address this challenge, we establish a method for identifying multiple targets of chemical agents through analyzing the module profiles of gene expression upon chemical treatments. By using ...
