However, log-ratios are often used for analysis and visualization of fold changes. The logarithm to base 2 is most commonly used, [ 8 ] [ 9 ] as it is easy to interpret, e.g. a doubling in the original scaling is equal to a log 2 fold change of 1, a quadrupling is equal to a log 2 fold change of 2 and so on.
q c is impact pressure (dynamic pressure) and; p is static pressure; is the ratio of specific heat of a gas at a constant pressure to heat at a constant volume (1.4 for air) The formula to compute Mach number in a supersonic compressible flow is derived from the Rayleigh supersonic pitot equation:
The log function is understood to be base-10 (as is customary in engineering fields): if x = log(y), then y = 10 x.

The period of c / k , for c coprime to k, equals the period of 1 / k . If k = 2 a ·5 b n where n > 1 and n is not divisible by 2 or 5, then the length of the transient of 1 / k is max(a, b), and the period equals r, where r is the multiplicative order of 10 mod n, that is the smallest integer such that 10 r ≡ 1 (mod n).
35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...
Band diagrams for a straddling-gap type heterojunction, as understood by Anderson's rule. The junction alignment at equilibrium (bottom) is predicted based on a hypothetical flat-vacuum alignment (top).
