In particle physics, lepton number (historically also called lepton charge) [1] is a conserved quantum number representing the difference between the number of leptons and the number of antileptons in an elementary particle reaction. [2]
C character classification is a group of operations in the C standard library that test a character for membership in a particular class of characters; such as alphabetic, control, etc. Both single-byte, and wide characters are supported.
In array languages, operations are generalized to apply to both scalars and arrays. Thus, a+b expresses the sum of two scalars if a and b are scalars, or the sum of two arrays if they are arrays. An array language simplifies programming but possibly at a cost known as the abstraction penalty.

The Germanium Detector Array (GERDA) collaboration's result of phase I of the detector was a limit of > years (90% C.L.). [23] It used germanium both as source and detector material. [23] Liquid argon was used for muon vetoing and as a shielding from background radiation. [23]
The experiment is designed to conduct precision tests of the Standard Model by studying rare decays of charged kaons.The principal goal, for which the design has been optimized, is the measurement of the rate of the ultra-rare decay K + → π + + ν + ν with a precision of 10%, by detecting about 100 decay candidates with low background.
For every type T, except void and function types, there exist the types "array of N elements of type T". An array is a collection of values, all of the same type, stored contiguously in memory. An array of size N is indexed by integers from 0 up to and including N−1. Here is a brief example:
c = a + b In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also ...
