The concept arose from the devastating Copenhagen polio epidemic of 1952, which resulted in hundreds of victims experiencing respiratory and bulbar failure. Over 300 patients required artificial ventilation for several weeks. This was provided by 1,000 medical and dental students who were(More)
Aortoesophageal fistulas are a rare but commonly fatal complication of esophageal cancer. Reports of successfully managed cases are few, with high mortality and morbidity usually resulting from failure to control the initial massive haemodynamic insult. We report the case of a 47-year-old Caucasian man with recently diagnosed advanced esophageal cancer who(More)
In preparing for the NASA Artificial Gravity Pilot Study the planned centrifuge loading protocol was tested in 11 ambulatory subjects (6 men, 5 women). Each was subjected to a single 60 min trial with 2.5G of equivalent gravitational load feet and 1G at the level of the mediastinum. Amongst the men, 5/6 completed the trial successfully with no adverse(More)
— An all-digital de-skew clock generator for arbitrary wide range delay is proposed to minimize the instability of the clock settling while achieving fast locking time. The clock skew problem is detrimental in high-speed applications, especially when the skew is longer than multi-cycles. The proposed clock generator was fabricated in a 0.18-μ μm CMOS(More)
