BACKGROUND Seizures are a common manifestation of neurological disease in the neonatal foal and are an important cause of morbidity and mortality in this population. Current antiepileptic options are effective, but often have undesirable adverse effe

We present results from simultaneous multiwavelength X-ray, radio, and optical/near-infrared observations of the quiescent black hole X-ray binary A0620-00 performed in 2013 December. We find that the Chandra flux has brightened by a factor of 2 sinc

The minimum intensities of sunspot umbrae were measured from 1992 through 2003 using the National Solar Observatory Kitt Peak Vacuum Telescope spectromagnetograph data. The resulting 3931 umbral measurements reveal a solar cycle variation in the umbr

We examine ~10 years of photometric data and find that the black hole X-ray binary V4641 Sgr has two optical states, passive and active, during X-ray quiescence. The passive state is dominated by ellipsoidal variations and is stable in the shape and

Understanding how black holes accrete and supply feedback to their environment is one of the outstanding challenges of modern astrophysics. Swift J1910.2-0546 is a candidate black hole low-mass X-ray binary that was discovered in 2012 when it entered

There are few controlled pediatric studies comparing the various modes of ventilation in terms of patient outcomes. Thus at this time the choice of ventilator mode depends largely on the apparatus available, the patient's disease state, and personal

Summary: Mycelia from four mutants of Aspergillus nidulans impaired in penicillin production at separate genetic loci were treated with an enzyme complex capable of lysing cell walls, then mixed in all possible paired combinations and grown in osmoti

An iron-complexing antibiotic with a narrow spectrum of biological activity was produced by several strains of Aspergillus nidulans when grown in a low-iron, chemically defined medium. Its chemical and biological properties closely resembled those of

SUMMARY: Heterozygous diploids were produced between a wild-type strain of Penicillium chrysogenum and two strains derived from it. The derived strains had been isolated after several and latterly divergent selection steps, selection being made at ea
