Examples More than a hundred power-law distributions have been identified in physics (e.g. sandpile avalanches), biology (e.g. species extinction and body mass), and the social sciences (e.g. city sizes and income). Among them are: Astronomy Kepler's third law The initial mass function of stars The differential energy...

Ensemble (mathematical physics)
Suppose we have a preparation procedure for a system in a physics lab: For example, the procedure might involve a physical apparatus and some protocols for manipulating the apparatus. As a result of this preparation procedure, some system is produced and maintained in isolation for some small period of time. By repeat...

Lempel–Ziv–Markov chain algorithm
The description below is based on the XZ for Java encoder by Lasse Collin, which appears to be the most readable among several rewrites of the original 7-zip using the same algorithms: again, while citing source code as reference is not ideal, any programmer should be able to check the claims below with a few hours of ...

Sampling (statistics)
Sampling methods Within any of the types of frames identified above, a variety of sampling methods can be employed, individually or in combination. Factors commonly influencing the choice between these designs include: Nature and quality of the frame Availability of auxiliary information about units on the frame Acc...

Mainframe computer
Differences from supercomputers A supercomputer is a computer at the leading edge of data processing capability, with respect to calculation speed. Supercomputers are used for scientific and engineering problems (high-performance computing) which crunch numbers and data, while mainframes focus on transaction processing...

Computational problem
A counting problem can be represented by a function f from {0, 1}* to the nonnegative integers. For a search relation R, the counting problem associated to R is the function fR(x) = |{y: R(x, y) }|. Optimization problem An optimization problem asks for finding a "best possible" solution among the set of all possible so...

Functional specialization (brain)
A remarkable precedent of this orientation is the research of Justo Gonzalo on brain dynamics where several phenomena that he observed could not be explained by the traditional theory of localizations. From the gradation he observed between different syndromes in patients with different cortical lesions, this author p...
