Prostate specific antigen (PSA) 40–49 years: 1.2–2.9 [75] μg/L [5] [15] or ng/mL [23] More detailed cutoffs in PSA – Serum levels: 70–79 years, non-African-American: 4.0–9.0 [75] 70–79 years, African-American: 7.7–13 [75] PAP: 3 [23] units/dL (Bodansky units) Calcitonin: 5, [76] 15 [76] ng/L or pg/mL: Cutoff against medullary ...
Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.
The AB magnitude zero point is defined such that an object's AB and Vega-based magnitudes will be approximately equal in the V filter band. However, the AB magnitude system is defined assuming an idealized detector measuring only one wavelength of light, while real detectors accept energy from a range of wavelengths.
Most countries forbid operation of motor vehicles and heavy machinery above prescribed levels of blood alcohol content. Operation of boats and aircraft is also regulated. Some jurisdictions also regulate bicycling under the influence. The alcohol level at which a person is considered legally impaired to drive varies by country.

A gradient-index lens with a parabolic variation of refractive index (n) with radial distance (x). The lens focuses light in the same way as a conventional lens. If the refractive index of a medium is not constant but varies gradually with the position, the material is known as a gradient-index (GRIN) medium and is described by gradient index ...
