clinics. National surveillance data based on STD clinic data may not provide reliable information about the treatment of STDs, because an estimated 40–60% of STD cases are treated outside of STD clinics.3 Our objectives in this article are to provide population-based estimates of the prevalence of patient-reported STDs and to characterize patterns of treatment utilization according to specific ...

IT Failure Rates--70% or 10-15%?

T his is a closed-book quiz. Quick, now— what percentage of software projects fail? Let me hazard a guess as to your answer. Odds are, you said something like " 70 percent. " Am I right? Now, I want to analyze why you said whatever you said. A friend of mine, Nicholas Zvegintzov (the Chief Guru of software maintenance), likes to say that, if you track down the sources of the things we " know " ...

87Sr lattice clock with inaccuracy below 10 -15.

Aided by ultrahigh resolution spectroscopy, the overall systematic uncertainty of the 1S0-3P0 clock resonance for lattice-confined 87Sr has been characterized to 9 x 10(-16). This uncertainty is at a level similar to the Cs-fountain primary standard, while the potential stability for the lattice clocks exceeds that of Cs. The absolute frequency of the clock transition has been measured to be 42...
