Functional derivative — In mathematics and theoretical physics, the functional derivative is a generalization of the directional derivative. The difference is that the latter differentiates in the direction of a vector, while the former differentiates in the direction… … Wikipedia
Gradient descent — For the analytical method called steepest descent see Method of steepest descent. Gradient descent is an optimization algorithm. To find a local minimum of a function using gradient descent, one takes steps proportional to the negative of the… … Wikipedia

Temperature gradient gel electrophoresis — (TGGE) and Denaturing Gradient Gel Electrophoresis (DGGE) are forms of electrophoresis which use either a temperature or chemical gradient to denature the sample as it moves across an acrylamide gel. TGGE and DGGE can be applied to nucleic acids… … Wikipedia
Hybrid functional — A hybrid functional is an exchange correlation functional used in density functional theory (DFT) that incorporates a portion of exact exchange from Hartree Fock theory with exchange and correlation from other sources ( ab initio , such as LDA,… … Wikipedia
Immobilized pH gradient — (IPG) gels are the acrylamide gel matrix co polymerized with the pH gradient, which result a completely stable gradients except the most alkaline (>12) pH values. The immobilized pH gradient is obtained by the continuous change in the ratio of… … Wikipedia
