- list comprehension — (functional programming) An expression in a functional language denoting the results of some operation on (selected) elements of one or more lists. An example in Haskell: This returns all pairs of numbers (x,y) where x and y are elements of the list 1, 2, ..., 10, y <= x and their sum is less than 10. A list comprehension is simply "syntactic sugar" for a combination of applications of the functions, concat, map and filter. For instance the above example could be written: The term "list comprehension" appears in the references below. The earliest reference to the notation is in Rod Burstall and John Darlington's description of their language, NPL. David Turner subsequently adopted this notation in his languages SASL, KRC and Miranda, where he has called them "ZF expressions", set abstractions and list abstractions (in his 1985 FPCA paper [Miranda: A Non-Strict Functional Language with Polymorphic Types]).

In the C programming language, it is !A and in digital circuit design, /A.
- logical positivism — a philosophical movement that stresses the function of philosophy as a method of criticizing and analyzing science and that rejects all transcendental metaphysics, statements of fact being held to be meaningful only if they have verifiable consequences in experience and in statements of logic, mathematics, or philosophy itself, and with such statements of fact deriving their validity from the rules of language.

- netscape navigator — (networking, tool, product) /Mozilla/ (Often called just "Netscape") A web browser from Netscape Communications Corporation. The first beta-test version was released free to the Internet on 13 October 1994.

It features integrated support for sending electronic mail and reading Usenet news, as well as RSA encryption to allow secure communications for commercial applications such as exchanging credit card numbers with net retailers. It provides multiple simultaneous interruptible text and image loading; native inline JPEG image display; display and interaction with documents as they load; multiple independent windows. Netscape was designed with 14.4 kbps modem links in mind. You can download Netscape Navigator for evaluation, or for unlimited use in academic or not-for-profit environments. You can also pay for it. Version: 1.0N. E-mail: <[email protected]>.
- neutrosophic logic — (logic) (Or "Smarandache logic") A generalisation of fuzzy logic based on Neutrosophy. A proposition is t true, i indeterminate, and f false, where t, i, and f are real values from the ranges T, I, F, with no restriction on T, I, F, or the sum n=t+i+f. Neutrosophic logic thus generalises: - intuitionistic logic, which supports incomplete theories (for 0
