Clostridium difficile infection (CDI) is associated with increased cost, morbidity, and mortality in postoperative patients. Variable rates of postoperative CDI are reported among 4 surgical specialties during the 30-month study period. Risk factors for CDI include antibiotic use, increased ASA score, and increased admissions in the past year. Infect Control Hosp Epidemiol 2017;38:1254-1257.
We propose a method to extend the frequency range of polarization entanglement in periodically poled rubidium-doped potassium titanyl phosphate (Rb:KTP) waveguides. Our calculations predict that output wavelengths from 1130 nm to 1257 nm may be achieved using Rb:KTP by the appropriate selection of a direction of propagation for the waveguide. The fidelity using a poling period of 1 mm is approx...
قدرت گرفتن و به سلطنت رسیدن رضاشاه، محصول همراهى جمعى از روشنفکران و فعالان سیاسى و فکرى، براى پایان دادن به وضع پرآشوب کشور و استقرار تمرکز سیاسى و برقرارى نظم و امنیت در کشور بود. یکى از روشنفکرانى که در آن زمان یار رضاخان شد و او را تا رسیدن به سلطنت و بعد از آن همراهى کرد، عبدالحسین تیمورتاش بود. وى بعد از رسیدن رضاشاه به سلطنت، به پاس زحماتش، به وزارت دربار پهلوى انتخاب شد و در این سمت نیز...
We report the detection of the millisecond pulsar B1257+12 with the Chandra X-ray Observatory. In a 20 ks exposure we detected 25 photons from the pulsar, with energies between 0.4 and 2.0 keV, corresponding to the flux F X = (4.4 ± 0.9) × 10 −15 ergs s −1 cm −2 in this energy range. The X-ray spectrum can be described by a power-law model with photon index Γ ≈ 2.8 and luminosity L X ≈ 2.5 × 10...
Investigating grain growth in southern protoplanetary disks Page 18 As we enter the 2006 millimetre observing season at the ATNF, the installation of the ATNF’s newest and most versatile spectrometer is now complete. The MOPra Spectrometer (MOPS) recently completed the final stages of testing on the Mopra millimetre telescope and observations have commenced for 2006, with fascinating results al...

Context. The substellar triple system VHS J125601.92−125723.9 (hereafter 1256−1257) is composed of an equal-mass M7.5 brown dwarf binary and L7 low-mass object. In Guirado et al. (2018, A&A, 610, A23) we published the detection radio emission at 8.4 GHz coming from central making it excellent target for further observations. Aims. We aim to identify origin occurring in 1256−1257 while discu...
