A disjunctive sequence is an infinite sequence (over a finite alphabet of characters) in which every finite string appears as a substring. For instance, the binary Champernowne sequence
formed by concatenating all binary strings in shortlex order, clearly contains all the binary strings and so is disjunctive. (The spaces above are not significant and are present solely to make clear the boundaries between strings). The complexity function of a disjunctive sequence S over an alphabet of size k is pS(n) = kn.
Any normal sequence (a sequence in which each string of equal length appears with equal frequency) is disjunctive, but the converse is not true. For example, letting 0n denote the string of length n consisting of all 0s, consider the sequence
obtained by splicing exponentially long strings of 0s into the shortlex ordering of all binary strings. Most of this sequence consists of long runs of 0s, and so it is not normal, but it is still disjunctive.
A disjunctive sequence is recurrent but never uniformly recurrent/almost periodic.
Lexicon is a card game published by Winning Moves UK, and formerly by Waddingtons, in the United Kingdom. It was originally created by David Whitelaw in 1933. Certain copies came with a 1936 competition slip wherein £1000 was offered in cash prizes . Several subsequent versions have been released.
The lexicon of a language is its vocabulary.
Lexicon is also a synonym for a dictionary or encyclopedic dictionary, and may also refer to:
Dusk is the darkest stage of twilight in the evening. Pre-dusk, during early to intermediate stages of twilight, there may be enough light in the sky under clear-sky conditions to read outdoors without artificial illumination, but at the end of civil twilight, when the earth rotates to a point at which the center of the sun is at 6° below the local horizon, artificial illumination is required to read outside.
The time of dusk can be thought of relative to the time of twilight, which has several alternative technical definitions:
Dusk! is a premium monthly subscription television channel. Established in 2009, Dusk! is the first and only adult TV channel in the world aimed at a female audience. Demand for female-oriented adult films, porna or women's erotica has been increasing for many years and is becoming increasingly accepted. Dusk! believes women have their own fantasies and needs and therefore require a different kind of adult films. By questioning its female users via an online panel, Dusk! has become an expert in this area. Dusk! is available in The Netherlands on the platforms of Ziggo, UPC Netherlands, CAIW and KPN and broadcasts 24/7. The channel is owned by 2GrapesMedia.
Dusk! offers a unique and diverse mix of mainly adult films and scenes, from all over the world and from a female point of view, and adult films in the genre of feminist pornography. The information provided by the online panel is the main guideline for selection, enabling to stay up to date with tastes, opinions and likes and dislikes regarding adult content for women. Content rejected by the panel is not broadcast. This method of selecting films has resulted in a new genre within the adult entertainment industry: porna.
Dusk is the fourth studio album by The The, recorded in 1992 and released by Sony Records in January 1993. The album peaked at #2 in the UK, and at #142 in America. In 2002 the album was reissued in remastered form on CD.
