Citrus
Citrus is a common term and genus (Citrus) of flowering plants in the rue family, Rutaceae.
The most recent research indicates an origin in Australia, New Caledonia and New Guinea. Some researchers believe that the origin is in the part of Southeast Asia bordered by Northeast India, Burma (Myanmar) and the Yunnan province of China, and it is in this region that some commercial species such as oranges, mandarins, and lemons originated. Citrus fruit has been cultivated in an ever-widening area since ancient times; the best-known examples are the oranges, lemons, grapefruit, and limes. Despite some superficial similarities, pineapple is not closely related to citrus.
History
At various times, citrus plants were thought to be native to Asia (where they were first domesticated), Europe, and Florida. But the European oranges (such as the bitter orange) were originally brought from India at around the time of Alexander the Great, and the "native" oranges of Florida actually originated with the Spanish Conquistadors only a few centuries earlier. The lemon reached Europe during the time of classical Rome.
Citrus (album)
Citrus is the second studio album by New York-based shoegazing band Asobi Seksu. It was released on May 30, 2006 through Friendly Fire Recordings in the US, and on August 13, 2007 in Europe by One Little Indian Records. Three singles were released from the album: "Thursday" in August 2007, "Strawberries" in November 2007, and "Goodbye" in March 2008. The song "Thursday" was featured in episode 1 of season 2 of the British TV series Skins, and the songs "Lions and Tigers" and "Nefi + Girly" were featured in the first episode of season 3 of Skins.

Personnel
Citrus (band)
Citrus was a Japanese indie-pop band on the Trattoria Records label founded by Oyamada Keigo (aka Cornelius). It was formed in 1990 by Takeaki Emori (江森丈晃, Emori Takeaki) and Michiko Endō (遠藤倫子, Endō Michiko). They released a number of cassette tapes and EPs before they broke up in 2001 without releasing an album.

Rank of a partition
In mathematics, particularly in the fields of number theory and combinatorics, the rank of a partition of a positive integer is a certain integer associated with the partition. In fact at least two different definitions of rank appear in the literature. The first definition, with which most of this article is concerned, is that the rank of a partition is the number obtained by subtracting the number of parts in the partition from the largest part in the partition. The concept was introduced by Freeman Dyson in a paper published in the journal Eureka. It was presented in the context of a study of certain congruence properties of the partition function discovered by the Indian mathematical genius Srinivasa Ramanujan. A different concept, sharing the same name, is used in combinatorics, where the rank is taken to be the size of the Durfee square of the partition.
Definition
By a partition of a positive integer n we mean a finite multiset λ = { λk, λk − 1, . . . , λ1 } of positive integers satisfying the following two conditions:
Organ stop
An organ stop (or just stop) is a component of a pipe organ that admits pressurized air (known as wind) to a set of organ pipes. Its name comes from the fact that stops can be used selectively by the organist; some can be "on" (admitting the passage of air to certain pipes), while others can be "off" (stopping the passage of air to certain pipes).
The term can also refer to the control that operates this mechanism, commonly called a stop tab, stop knob, or drawknob. On electric or electronic organs that imitate a pipe organ, the same terms are often used, with the exception of the Hammond organ and clonewheel organs, which use the term "drawbar".
The term is also sometimes used as a synonym for register, referring to rank(s) of pipes controlled by a single stop. Registration is the art of combining stops.
Mechanics
Organ pipes are physically organized within the organ according to note and timbre, into sets. A set of pipes producing the same timbre for each note is called a rank, while each key on a pipe organ controls a note which may be sounded by different ranks of pipes, alone or in combination. The use of stops enables the organist to selectively turn off ("stop") certain ranks in order to produce different combinations of sounds, as opposed to hearing all sounds simultaneously. While nowadays one speaks of "drawing" a stop to select a particular rank, the earliest organs were constructed as blockwerk with all ranks 'on' by default.
