https://en.wikipedia.org/wiki/Syntactic%20predicate | A syntactic predicate specifies the syntactic validity of applying a production in a formal grammar and is analogous to a semantic predicate that specifies the semantic validity of applying a production. It is a simple and effective means of dramatically improving the recognition strength of an LL parser by providing ... |
https://en.wikipedia.org/wiki/Bioastronautics | Bioastronautics is a specialty area of biological and astronautical research which encompasses numerous aspects of biological, behavioral, and medical concern governing humans and other living organisms in a space flight environment; and includes design of payloads, space habitats, and life-support systems. In short, ... |
https://en.wikipedia.org/wiki/A-MAC | In television electronics, A-MAC carries digital information: sound, and data-teletext on an FM subcarrier at 7 MHz. Since the vision bandwidth of a standard MAC signal is 8.4 MHz, the horizontal resolution on A-MAC has to be reduced to make room for the 7 MHz carrier. A-MAC has not been used in service.

https://en.wikipedia.org/wiki/B-MAC | B-MAC is a form of analog video encoding, specifically a type of Multiplexed Analogue Components (MAC) encoding. MAC encoding was designed in the mid 80s for use with Direct Broadcast Satellite systems. Other analog video encoding systems include NTSC, PAL and SECAM. Unlike the FDM method used in those, MAC encoding... |
https://en.wikipedia.org/wiki/C-MAC | C-MAC is the television technology variant approved by the European Broadcasting Union (EBU) for satellite transmissions. The digital information is modulated using 2-4PSK (phase-shift keying), a variation of quadrature PSK where only two of the phaser angles (±90°) are used.
The data capacity for C-MAC is 3 Mbit/s.

https://en.wikipedia.org/wiki/D-MAC | Among the family of MAC or Multiplexed Analogue Components systems for television broadcasting, D-MAC is a reduced bandwidth variant designed for transmission down cable.
The data is duobinary coded with a data burst rate of 20.25Mbit/s so that 0° as well as ±90° phasors are used.
D-MAC has a bandwidth of 8.4 MHz ve... |
https://en.wikipedia.org/wiki/D2-MAC | D2-MAC is a satellite television transmission standard, a member of Multiplexed Analogue Components family. It was created to solve D-MAC's bandwidth usage by further reducing it, allowing usage of the system on cable and satellite broadcast. It could carry four high quality (15 kHz bandwidth) sound channels or eight l... |
https://en.wikipedia.org/wiki/C-squares | C-squares (acronym for the Concise Spatial QUery And REpresentation System) is a system of spatially unique, location-based identifiers (geocodes) for areas on the surface of the earth, represented as cells from a latitude- and longitude-based Discrete Global Grid at a hierarchical set of resolution steps, obtained by ... |
https://en.wikipedia.org/wiki/Osteophagy | Osteophagy is the practice in which animals, usually herbivores, consume bones. Most vegetation around the world lacks sufficient amounts of phosphate. Phosphorus is an essential mineral for all animals, as it plays a major role in the formation of the skeletal system, and is necessary for many biological processes inc... |
https://en.wikipedia.org/wiki/Ambient%20isotopy | In the mathematical subject of topology, an ambient isotopy, also called an h-isotopy, is a kind of continuous distortion of an ambient space, for example a manifold, taking a submanifold to another submanifold. For example in knot theory, one considers two knots the same if one can distort one knot into the other with... |
