This paper presents a retrospective view of the Charlotte distributed operating system, which is intended as a testbed for developing techniques and tools for exploiting large-grain parallelism to solve computation-intensive problems. Charlotte was constructed over the course of approximately 5 years, going through several distinct versions as the(More)
This paper presents a retrospective view of the Charlotte distributed operating system, a testbed for developing techniques and tools to solve computation-intensive problems with large-grain paral-lelism. The final version of Charlotte runs on the Crystal multicom-puter, a collection of VAX-111750 computers connected by a local-area network. The(More)
RP3, the Research Parallel Processing Prototype, was a research vehicle for exploring the hardware and software aspects of highly parallel computation. RP3 was a shared-memory machine that was designed to be scalable to 512 processors; a 64-processor machine was in operation from October 1988 through March 1991. A parallel-programming environment based on(More)
Approximately 15% of preterm infants may develop postnatal cytomegalovirus (CMV) infection from seropositive mothers via breast milk and are at risk for neurological sequelae in childhood. The aims of this study were to assess the effects and outcomes on growth, neurodevelopmental status, and hearing in very low birth weight (VLBW) premature infants with(More)
BACKGROUND Some oral probiotics have been shown to prevent necrotizing enterocolitis (NEC) and decrease mortality effectively in preterm very low birth weight (PVLBW) infants. However, it is unclear whether a single probiotic or a mixture of probiotics is most effective for the prevention of NEC. OBJECTIVE A meta-analysis was conducted by reviewing the(More)
