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/Duffy%20binding%20proteins | In molecular biology, Duffy binding proteins are found in Plasmodium. Plasmodium vivax and Plasmodium knowlesi merozoites invade Homo sapiens erythrocytes that express Duffy blood group surface determinants. The Duffy receptor family is localised in micronemes, an organelle found in all organisms of the phylum Apicompl... |

Since its foundation in 1962, it has hosted distinguished physicists for short-term visits during seasonal winter and summer programs, to promote collaborat... |
https://en.wikipedia.org/wiki/Skip%20counting | Skip counting is a mathematics technique taught as a kind of multiplication in reform mathematics textbooks such as TERC. In older textbooks, this technique is called counting by twos (threes, fours, etc.).
In skip counting by twos, a person can count to 10 by only naming every other even number: 2, 4, 6, 8, 10. Comb... |
https://en.wikipedia.org/wiki/Halting%20problem | In computability theory, the halting problem is the problem of determining, from a description of an arbitrary computer program and an input, whether the program will finish running, or continue to run forever. The halting problem is undecidable, meaning that no general algorithm exists that solves the halting problem ... |
https://en.wikipedia.org/wiki/Multitape%20Turing%20machine | A multi-tape Turing machine is a variant of the Turing machine that utilizes several tapes. Each tape has its own head for reading and writing. Initially, the input appears on tape 1, and the others start out blank.
This model intuitively seems much more powerful than the single-tape model, but any multi-tape machine—... |
https://en.wikipedia.org/wiki/1-Ethyl-3-%283-dimethylaminopropyl%29carbodiimide | 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride.
It is typically employed in the 4.0-6.0 pH range. It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds. While other carbodiimid... |
https://en.wikipedia.org/wiki/Peanut%20oil | Peanut oil, also known as groundnut oil or arachis oil, is a vegetable oil derived from peanuts. The oil usually has a mild or neutral flavor but, if made with roasted peanuts, has a stronger peanut flavor and aroma. It is often used in American, Chinese, Indian, African and Southeast Asian cuisine, both for general co... |
