ABSTRACT
The discrepancy between observations from γ-ray astronomy of the ^{60}Fe/^{26}Al γ-ray flux ratio and recent calculations is an unresolved puzzle in nuclear astrophysics. The stellar ß-decay rate of ^{59}Fe is one of the major nuclear uncertainties impeding us from a precise prediction. The important Gamow-Teller strengths from the low-lying states in ^{59}Fe to the ^{59}Co ground state are measured for the first time using the exclusive measurement of the ^{59}Co(t,^{3}He+γ)^{59}Fe charge-exchange reaction. The new stellar decay rate of ^{59}Fe is a factor of 3.5±1.1 larger than the currently adopted rate at T=1.2 GK. Stellar evolution calculations show that the ^{60}Fe production yield of an 18 solar mass star is decreased significantly by 40% when using the new rate. Our result eliminates one of the major nuclear uncertainties in the predicted yield of ^{60}Fe and alleviates the existing discrepancy of the ^{60}Fe/^{26}Al ratio.
ABSTRACT
The developers of three new databases propose to evaluate computer-based patient record systems in great detail. They promise to rigorously benchmark how CPR systems perform on a suite of tests in what they are calling a 'CPR certification laboratory.'

The time has come for healthcare providers to stop hoarding information. By building healthcare information networks, providers at all levels can gain a competitive edge not by "owning" information, but by better using richer, more complete, "shared" information.

The abundance and sophistication of technology can lead to solutions before a problem is understood. To maintain a proper focus on problem-solving, the second part of this series explains that we must be willing to rethink and redefine existing problems.

As information professionals, our challenge is to coordinate specialized resources from multiple entities. By transparently integrating the technical processes, users will be able to focus on the management purposes of their systems rather than how their information is obtained and manipulated.
