Directed set         
NONEMPTY SET; GENERALIZATION OF NONEMPTY TOTALLY ORDERED SETS
Upward directed set; Upward-directed set; Directed preorder; Filtered set; Directed subset
In mathematics, a directed set (or a directed preorder or a filtered set) is a nonempty set A together with a reflexive and transitive binary relation \,\leq\, (that is, a preorder), with the additional property that every pair of elements has an upper bound.Kelley, p.
directed set         
NONEMPTY SET; GENERALIZATION OF NONEMPTY TOTALLY ORDERED SETS
Upward directed set; Upward-directed set; Directed preorder; Filtered set; Directed subset
<theory> A set X is directed under some relation, <= (less than or equal), if it is non-empty and if for any two elements x and y there exists an element z such that x <= z and y <= z. I.e. all pairs have an upper bound. (1994-11-11)

SET OF CRITICAL CARE PRACTICES
Early Goal Directed Therapy (EGDT); Goal-Directed Therapy (GDT); Goal-directed therapy; Early goal directed therapy
Early goal-directed therapy (GDT) was introduced by Emanuel P. Rivers in The New England Journal of Medicine in 2001 and is a technique used in critical care medicine involving intensive monitoring and aggressive management of perioperative hemodynamics in patients with a high risk of morbidity and mortality.
Directed evolution         
  • artificial compartments]], right). Either way ensures that the gene can be isolated based on the activity of the encoded protein.
  • Shuffling]] recombines segments of two (or more) similar genes.
  • Directed evolution is analogous to climbing a hill on a '[[fitness landscape]]' where elevation represents the desired property. Each round of selection samples mutants on all sides of the starting template (1) and selects the mutant with the highest elevation, thereby climbing the hill. This is repeated until a local summit is reached (2).
  • random mutagenesis]] sample sequence space. The amino acid substituted into a given position is shown. Each dot or set of connected dots is one member of the library. Error-prone PCR randomly mutates some residues to other amino acids. Alanine scanning replaces each residue of the protein with alanine, one-by-one. Site saturation substitutes each of the 20 possible amino acids (or some subset of them) at a single position, one-by-one.
METHOD USED IN PROTEIN ENGINEERING THAT MIMICS THE PROCESS OF NATURAL SELECTION TO STEER PROTEINS OR NUCLEIC ACIDS TOWARD A USER-DEFINED GOAL
Directed molecular evolution
Directed evolution (DE) is a method used in protein engineering that mimics the process of natural selection to steer proteins or nucleic acids toward a user-defined goal. It consists of subjecting a gene to iterative rounds of mutagenesis (creating a library of variants), selection (expressing those variants and isolating members with the desired function) and amplification (generating a template for the next round).

A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel, missiles, vehicles, and optical devices.

(DAG) A directed graph containing no cycles. This means that if there is a route from node A to node B then there is no way back. (1994-12-07)

In mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG) is a directed graph with no directed cycles. That is, it consists of vertices and edges (also called arcs), with each edge directed from one vertex to another, such that following those directions will never form a closed loop.
Site-directed mutagenesis         
  • Depiction of one common way to clone a site-directed mutagenesis library (i.e., using degenerate oligos). The gene of interest is PCRed with oligos that contain a region that is perfectly complementary to the template (blue), and one that differs from the template by one or more nucleotides (red). Many such primers containing degeneracy in the non-complementary region are pooled into the same PCR, resulting in many different PCR products with different mutations in that region (individual mutants shown with different colors below).
  • Site saturation mutagenesis is a type of site-directed mutagenesis. This image shows the saturation mutagenesis of a single position in a theoretical 10-residue protein. The wild type version of the protein is shown at the top, with M representing the first amino acid methionine, and * representing the termination of translation. All 19 mutants of the isoleucine at position 5 are shown below.
MOLECULAR BIOLOGY TECHNIQUE
Site-specific mutagenesis; Mutagenesis, site-directed; Targeted mutagenesis; PCR mutagenesis; In vitro mutagenesis; CRISPR mutagenesis
Site-directed mutagenesis is a molecular biology method that is used to make specific and intentional mutating changes to the DNA sequence of a gene and any gene products. Also called site-specific mutagenesis or oligonucleotide-directed mutagenesis, it is used for investigating the structure and biological activity of DNA, RNA, and protein molecules, and for protein engineering.
