A USB-pluggable hardware true random number generator. In computing, a hardware random number generator (HRNG), true random number generator (TRNG), non-deterministic random bit generator (NRBG), [1] or physical random number generator [2] [3] is a device that generates random numbers from a physical process capable of producing entropy (in other words, the device always has access to a ...
Eye color is an example of a (physical) phenotypic trait. A phenotypic trait, [1] [2] simply trait, or character state [3] [4] is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two.

A scarf (pl.: scarves or scarfs) is a long piece of fabric that is worn on or around the neck, shoulders, or head. A scarf is used for warmth, sun protection, cleanliness, fashion, religious reasons, or to show support for a sports club or team. [ 1 ]
A neckerchief (from neck (n.) + kerchief [1]), sometimes called a necker, kerchief or scarf, is a type of neckwear associated with those working or living outdoors, including farm labourers, cowboys and sailors. It is most commonly still seen today in the Scouts, Girl Guides and other similar youth movements. A neckerchief consists of a ...
Arthur Kollmann (1858–1941) [1] was a German medical researcher from Hamburg who studied the fingerprint characteristics of friction ridges and volar pads. [2]In the 1880s (1883, 1885), Kollmann was the first researcher to address the formation of friction ridges on the fetus and the random physical stresses and tensions which may have played a part in their growth.
Pseudorandom number generator – Algorithm that generates an approximation of a random number sequence; Low-discrepancy sequence – Type of mathematical sequence; Random number generation – Producing a sequence that cannot be predicted better than by random chance; Pseudorandom noise – Pseudo-random signal with characteristics similar to ...
Other generating functions of random variables include the moment-generating function, the characteristic function and the cumulant generating function. The probability generating function is also equivalent to the factorial moment generating function , which as E [ z X ] {\displaystyle \operatorname {E} \left[z^{X}\right]} can also be ...
A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample being observed is large or small. Thus, conversely, if the property of a substance changes as the sample size changes, that property is not a characteristic ...
