The Solar System Algorithm: A Novel Metaheuristic Method for Global Optimization

open access: yesIEEE Access, 2021
A novel metaheuristic algorithm for global optimization, called the Solar System Algorithm (SSA), is presented. The proposed algorithm imitates the orbiting behavior of some objects found in the solar system: i.e., Sun, planets, moons, stars, and black ...

Liver-function Tests [PDF]

open access: yesBMJ, 1954
NUMEROUS attempts have been made for over half a century to measure the function of the liver by one or another test; these procedures have been proposed for several purposes. First, in cases in which the diagnosis is entirely obscure, it has been hoped that the presence of liver disease might be ruled in or out.

A New Representation of the k-Gamma Functions

open access: yesMathematics, 2019
The products of the form z ( z + l ) ( z + 2 l ) … ( z + ( k − 1 ) l ) are of interest for a wide-ranging audience. In particular, they frequently arise in diverse situations, such as computation of Feynman integrals ...

Test of the Universality of Naive-time-reversal-odd Fragmentation Functions [PDF]

open access: yes, 2010
We investigate the ''spontaneous'' hyperon transverse polarization in $e^+e^-$ annihilation and semi-inclusive deep inelastic scattering processes as a test of the universality of the naive-time-reversal-odd transverse momentum dependent fragmentation ...
