Question: What is the abbreviation to the magazine that called Qvwm  "an unusually impressive imposter"?

Context paragraphs:
Qvwm: Qvwm is a simple, lightweight window manager, which is intended to be a reimplementation of the Windows 95 interface for Linux systems.  Released in 1996 under the GNU General Public License (GNU GPL), it features a start menu, a taskbar incorporating a system tray, and Windows-like task-switching.  The project's name comes from wordplay references to Japanese words and Roman numbers.  In 2000, "Linux Format" called Qvwm "an unusually impressive imposter".

Linux Format: Linux Format was the UK's first Linux-specific magazine, and as of 2013 was the best-selling Linux title in the UK.  It is also exported to many countries worldwide.  It is published by Future plc (which produces "PC Plus", ". net" and many other computer magazines).  Linux Format is commonly abbreviated to LXF, and issues are referred to with LXF as a prefix followed by the issue number (for example LXF102 refers to the 102nd issue).

Hyperkalemic periodic paralysis: Hyperkalemic periodic paralysis (HYPP, HyperKPP) is a genetic disorder.  It occurs in humans, horses (where it is also known as Impressive syndrome, after an index case in a horse named Impressive, or possibly one of his ancestors), and perhaps other animals.  It is an inherited autosomal dominant disorder that affects sodium channels in muscle cells and the ability to regulate potassium levels in the blood.  It is most commonly associated with horses, but occurs in humans, where it may be called Gamstorp episodic adynamy.  It is characterized by muscle hyperexcitability or weakness which, exacerbated by potassium, heat or cold, can lead to uncontrolled shaking followed by paralysis.  Onset in humans usually occurs in early childhood, but still occurs with adults.

Andrée Belle: Andrée Belle (born in Paris) was a French painter.  She was a pupil of Jean-Charles Cazin (1840–1901).  She painted in oils and pastels, landscapes especially, of which she exhibited seventeen in June, 1902.  The larger part of these were landscape portraits.  The subjects were well represented, and the various hours of day, with characteristic lighting, unusually well rendered.  At the Salon des Beaux Arts, 1902, this artist exhibited a large pastel, "A Halt at St. Mammes" and a "Souvenir of Bormes", showing the tomb of Cazin.  In 1903, she exhibited a pastel called "Calvary," which became part of the collection of the Musée de Picardie at Amiens; it was praised for its harmony of color and the manner in which the rainbow is represented.  Her pictures of "Twilight" and "Sunset " are unusually successful.  She was a member of the Société Nationale des Beaux-Arts.

La Barranca: La Barranca has been a successful ongoing outfit for over a decade.  Based in Mexico City, they are led by guitarist and songwriter José Manuel Aguilera, who previously and concurrently worked with Sangre Azteka, Jaguares, Cecilia Toussaint, Steven Brown/Nine Rain (Tuxedomoon), and more.  He has an unusually economical style of playing that concentrates on great rhythms, superb tone, and very melodic solos.  After the original lineup—Aguilera, Federico Fong (bass), Alfonso Andre (drums), all of whom were guest members of Jaguares with former Caifanes frontman Saúl Hernández—went its separate ways, a second version of the band included Santa Sabina guitar virtuoso Alex Otaola and the extremely flexible rhythm section of brothers Jose María ("Chema") and Alonso Arreola.  The band's sound effortlessly moves from flat out rock to fusion-ish jamming and passes through a kind of Mexican folk influence along the way.  Aguilera is a good singer with a talent for finding simple melodies amidst rather complex songs.  On "El Fluir" the band decided to record live and to cut back on the keyboard and programmed additions to their music.  Surprisingly, the result was not an over-the-top jamfest but rather a very tightly arranged set of songs that hinted at the overwhelming power they could possess in concert.  The two guitar interplay between Aguilera and Otaola was highly impressive as they explored all forms of playing together and against one another (with Otaola pulling all sorts of radical sounds out of his guitar).  "El Fluir" was their first US release since "Tempestad" in 1998.  This edition was further sweetened by the inclusion of a previously unreleased bonus track and a video for the first single "Pare de Sufrir."

Supersingular elliptic curve: In algebraic geometry, supersingular elliptic curves form a certain class of elliptic curves over a field of characteristic "p" > 0 with unusually large endomorphism rings. Elliptic curves over such fields which are not supersingular are called "ordinary" and these two classes of elliptic curves behave fundamentally differently in many aspects.  discovered supersingular elliptic curves during his work on the Riemann hypothesis for elliptic curves by observing that in positive characteristic elliptic curves could have endomorphism rings of unusually large rank 4, and developed their basic theory.

Diànzǐ Yóuxì Ruǎnjiàn: Diànzǐ Yóuxì Ruǎnjiàn (literally: "Electronic Game Software" ; also known by the portmanteau abbreviation Diàn Ruǎn (电软; lit.  "Electro Soft")) is China's earliest video game magazine.  Founded in the summer of 1993 and officially serialized in May 1994 by China Association for Science and Technology (中国科学技术协会; Zhōngguó Kēxué Jìshù Xiéhuì), the magazine was originally subtitled Game Jízhōngyíng (GAME集中营; lit.  "Game Concentration Camp"), and focused on both PC games and console games.  In July 1995 it was closed by the government, however the publication ban was lifted two months later and the magazine was given the more politically palatable subtitle Game Fēngjǐngxiàn (GAME风景线; lit.  "Game Landscape").  Topical coverage broadened after this point to include articles on anime, comics, music, and popular culture in general, however the de-emphasis on video games created a rift among staff and several editors led by Bīng Suǒ (索冰; better known under the pseudonym "King") left the magazine to found "Diànzǐ Yóuxì yǔ Diànnǎo Yóuxì" (电子游戏与电脑游戏; lit.  "Electronic Games and Computer Games"; known by the portmanteau abbreviation "Diàn Diàn" (电电; lit.  "Electro Comp")), a rival magazine catering to a hardcore and doujin gamer ethic.

Kaizen Gamorra: Kaizen Gamorra is a fictional character in the Wildstorm Universe comics. Brandon Choi and Jim Lee had referred to him many times as an important character within the Wildstorm Universe, but their Kaizen Gamorra turned out to be an imposter called John Colt and the true Kaizen Gamorra appeared for the first time in Stormwatch #40, written by Warren Ellis, with art by Tom Raney.

Mid Oxfordshire (UK Parliament constituency): Mid Oxfordshire was a parliamentary constituency in Oxfordshire.  Unusually, its official name - Mid-Oxon - incorporated an abbreviation (Oxon, for Oxonia) but the full form of the county name was and is normally used in referring to the constituency.  During its existence Mid Oxfordshire returned one Member of Parliament to the House of Commons of the Parliament of the United Kingdom.

Big Tree at Victoria Falls: The Big Tree - one of the best-known trees in the world - is a huge baobab of the species "Adansonia digitata" in Zimbabwe, close to the Victoria Falls.  It has sometimes been called Livingstone's tree erroneously.  Unusually for a baobab it has both an impressive girth and is very tall.  It measures 22.40 metres in girth (2004) and is 24 metres tall (1985).
