Swim or Sink Together

Life vest: sink or swim.

Sink or swim--clinicians don't often counsel on drowning prevention.

OBJECTIVE Drowning is one of the leading causes of injury death for young children in the United States. This study examined primary care providers' knowledge of and counseling on drowning prevention. METHODS A random sample of 465 Los Angeles County pediatricians, family physicians, and pediatric nurse practitioners who serve families with young children received mailed questionnaires; 325 (...

A sea of standards for omics data: sink or swim?

In the era of Big Data, omic-scale technologies, and increasing calls for data sharing, it is generally agreed that the use of community-developed, open data standards is critical. Far less agreed upon is exactly which data standards should be used, the criteria by which one should choose a standard, or even what constitutes a data standard. It is impossible simply to choose a domain and have i...

Sink or swim together: necessary and sufficient conditions for finite moments of workload components in FIFO multiserver queues

Previously established necessary and sufficient conditions for finite stationary moments in stable FIFO GI/GI/s queues exist only for the first component of the workload vector, the delay. In this paper, we derive moment results for all the components of the stationary workload vector in stable FIFO GI/GI/s queues. As in the case of stationary delay, the moment conditions for workload component...

Sink or swim: strategies for cost-efficient diving by marine mammals.

Locomotor activity by diving marine mammals is accomplished while breath-holding and often exceeds predicted aerobic capacities. Video sequences of freely diving seals and whales wearing submersible cameras reveal a behavioral strategy that improves energetic efficiency in these animals. Prolonged gliding (greater than 78% descent duration) occurred during dives exceeding 80 meters in depth. Gl...
