Generalized oscillator strength for Na 3s-3p transition [PDF]
Phys Rev A Rapid Communications, vol 61, published 3 Feb, 2000, 2000 Generalized oscillator strengths (GOS's) for the Na $3s -3p$ transition have been investigated using the spin-polarized technique of the random phase approximation with exchange (RPAE) and the first Born approximation (FBA), focussing our attention on the position of the minimum.

Medicine's uncomfortable relationship with math: calculating positive predictive value.
JAMA Internal Medicine, 2014 In 1978, Casscells et al1 published a small but important study showing that the majority of physicians, house officers, and students overestimated the positive predictive value (PPV) of a laboratory test result using prevalence and false positive rate ...
