In most signaling schemes in digital communication, the boundaries of the decision regions are straight lines. For some of these schemes such as quadrature amplitude modulation and its special cases where the boundaries meet at right angles, simple and exact expressions are known for the probability of error on an AWGN channel. In other cases where the(More)
A randomised controlled trial was carried out to study the effect of 10 g of ascorbic acid taken during the first 2 1/2 days on the symptoms of the common cold. Altogether 1524 volunteers were recruited from a number of working groups in different parts of the country; 482 developed colds. There was no evidence that upper respiratory or general(More)
Many cellular functions are regulated by agonist-induced InsP(3)-evoked Ca2+ release from the internal store. In non-excitable cells, predominantly, the initial Ca2+ release from the store by InsP(3) is followed by a more sustained elevation in [Ca2+](i) via store-operated Ca2+ channels as a consequence of depletion of the store. Here, in smooth muscle, we(More)
There are reports in the literature of 20 or more trials designed to assess the efficacy of vitamin C (L-xyloascorbic acid, ascorbic acid, AA) in the prevention and treatment of the common cold. Many of the trials failed to satisfy strict criteria of scientific experimentation and it is generally concluded that AA supplementation has at best a small effect(More)
Family involvement is a key to realize the potential for long-lasting positive effects on physical, cognitive and psychosocial development of all babies, including those in the neonatal intensive care unit (NICU). Family-centered developmental care (FCDC) recognizes the family as vital members of the NICU health-care team. As such, families are integrated(More)
Parents will interact with a multitude of teams from various disciplines during their child's admission to the neonatal intensive care unit. Recognition of the emotional stressors experienced by these parents is a first step in working to provide the crucial support and parenting skills needed for bonding and caring for their infant from admission through(More)
