  2. Luhn algorithm - Wikipedia

    en.wikipedia.org/wiki/Luhn_algorithm

    Luhn algorithm. The Luhn algorithm or Luhn formula, also known as the " modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers. It is described in US patent 2950048A, granted on 23 August 1960. [ 1 ]

  3. ModR/M - Wikipedia

    en.wikipedia.org/wiki/ModR/M

    ModR/M is a byte that, if required, follows the opcode and specifies zero, one, or two operands for the instruction. [1]: §2.1. The format is: The "reg" field, if specifying an operand, encodes the three least-significant bits of a register index. Which register (general purpose, AVX, etc.) depends on the instruction being executed.

  4. Docking (molecular) - Wikipedia

    en.wikipedia.org/wiki/Docking_(molecular)

    In the field of molecular modeling, docking is a method which predicts the preferred orientation of one molecule to a second when a ligand and a target are bound to each other to form a stable complex. [1] Knowledge of the preferred orientation in turn may be used to predict the strength of association or binding affinity between two molecules ...

  5. Heckman correction - Wikipedia

    en.wikipedia.org/wiki/Heckman_correction

    Heckman correction. The Heckman correction is a statistical technique to correct bias from non-randomly selected samples or otherwise incidentally truncated dependent variables, a pervasive issue in quantitative social sciences when using observational data. [1] Conceptually, this is achieved by explicitly modelling the individual sampling ...

  6. Modulo - Wikipedia

    en.wikipedia.org/wiki/Modulo

    The properties involving multiplication, division, and exponentiation generally require that a and n are integers. Identity: (a mod n) mod n = a mod n. nx mod n = 0 for all positive integer values of x. If p is a prime number which is not a divisor of b, then abp−1 mod p = a mod p, due to Fermat's little theorem.

  7. Verbal arithmetic - Wikipedia

    en.wikipedia.org/wiki/Verbal_arithmetic

    Verbal arithmetic. Verbal arithmetic, also known as alphametics, cryptarithmetic, cryptarithm or word addition, is a type of mathematical game consisting of a mathematical equation among unknown numbers, whose digits are represented by letters of the alphabet. The goal is to identify the value of each letter. The name can be extended to puzzles ...

  9. Look Nevada - Wikipedia

    en.wikipedia.org/wiki/Look_Nevada

    Look 's Nevada, released in 1950, was the first recognizably modern alpine ski binding. The Nevada was only the toe portion of the binding, and was used with a conventional cable binding for the heel. An updated version was introduced in 1962 with a new step-in heel binding, the Grand Prix. These basic mechanisms formed the basis for LOOK ...
