https://en.wikipedia.org/wiki/Hyponastic%20response | In plant biology, the hyponastic response is a nastic movement characterized by an upward bending of leaves or other plant parts, resulting from accelerated growth of the lower side of the petiole in comparison to its upper part. This can be observed in many terrestrial plants and is linked to the plant hormone ethylen... |

https://en.wikipedia.org/wiki/Electroactive%20polymer | An electroactive polymer (EAP) is a polymer that exhibits a change in size or shape when stimulated by an electric field. The most common applications of this type of material are in actuators and sensors. A typical characteristic property of an EAP is that they will undergo a large amount of deformation while sustaini... |
https://en.wikipedia.org/wiki/H.248 | The Gateway Control Protocol (Megaco, H.248) is an implementation of the media gateway control protocol architecture for providing telecommunication services across a converged internetwork consisting of the traditional public switched telephone network (PSTN) and modern packet networks, such as the Internet. H.248 is... |
https://en.wikipedia.org/wiki/Perturbation%20%28astronomy%29 | In astronomy, perturbation is the complex motion of a massive body subjected to forces other than the gravitational attraction of a single other massive body. The other forces can include a third (fourth, fifth, etc.) body, resistance, as from an atmosphere, and the off-center attraction of an oblate or otherwise missh... |
https://en.wikipedia.org/wiki/Crosby%20system | The Crosby system was an FM stereophonic broadcasting standard developed by Murray G. Crosby. In the United States, it competed with, and ultimately lost to, the Zenith/GE system, which the FCC chose as the standard in 1961.
While both systems used multiplexing to transmit the L-R stereo signal, the Crosby system used... |
https://en.wikipedia.org/wiki/Grim%20trigger | In game theory, grim trigger (also called the grim strategy or just grim) is a trigger strategy for a repeated game.
Initially, a player using grim trigger will cooperate, but as soon as the opponent defects (thus satisfying the trigger condition), the player using grim trigger will defect for the remainder of the ite... |
https://en.wikipedia.org/wiki/Session%20border%20controller | A session border controller (SBC) is a network element deployed to protect SIP based voice over Internet Protocol (VoIP) networks.
Early deployments of SBCs were focused on the borders between two service provider networks in a peering environment. This role has now expanded to include significant deployments between... |
https://en.wikipedia.org/wiki/Primosome | In molecular biology, a primosome is a protein complex responsible for creating RNA primers on single stranded DNA during DNA replication.
The primosome consists of seven proteins: DnaG primase, DnaB helicase, DnaC helicase assistant, DnaT, PriA, Pri B, and PriC. At each replication fork, the primosome is utilized on... |
https://en.wikipedia.org/wiki/Sigil%20%28computer%20programming%29 | In computer programming, a sigil () is a symbol affixed to a variable name, showing the variable's datatype or scope, usually a prefix, as in $foo, where $ is the sigil.
Sigil, from the Latin sigillum, meaning a "little sign", means a sign or image supposedly having magical power. Sigils can be used to separate and de... |
https://en.wikipedia.org/wiki/Centrolecithal | Centrolecithal (Greek kentron = center of a circle, lekithos = yolk) describes the placement of the yolk in the centre of the cytoplasm of ova. Many arthropod eggs are centrolecithal.
During cytokinesis, centrolecithal zygotes undergo meroblastic cleavage, where the cleavage plane extends only to the accumulated yolk ... |
https://en.wikipedia.org/wiki/Language-oriented%20programming | Language-oriented programming (LOP) is a software-development paradigm where "language" is a software building block with the same status as objects, modules and components, and rather than solving problems in general-purpose programming languages, the programmer creates one or more domain-specific languages (DSLs) for... |
