The origins and development of the BESYS family of operating systems are traced. Developed at AT&T Bell Laboratories in the late fifties, the system was used for over ten years to control and facilitate the use of the IBM 704-709X series of. computers. Some of the novel operating system techniques created for the system and the people who produced them are chronicled.

The human prolyl-4-hydroxylase domain (PHD) proteins 1-3 are known as cellular oxygen sensors, acting via the degradation of hypoxia-inducible factor (HIF) α-subunits. PHD2 and PHD3 genes are inducible by HIFs themselves, suggesting a negative feedback loop that involves PHD abundance. To identify novel regulators of the PHD2 gene, an expression array of 704 transcription factors was screened b...

Heart rates, blood pressures, and functional responses to submaximal, maximal and postexertional treadmill testing are presented for a group of 704 healthy, asymptomatic aircrewmen referred to the USAF School of Aerospace Medicine. The indicated measurements are individually described by the use of percentiles. These data provide the practicing clinician with an accurate and complete descriptio...
