Omega (Ѡ ѡ or Ѡ ѡ; italics: Ѡ w or Ѡ ѡ) is a letter used in the early Cyrillic alphabet. Its name and form are derived from the Greek letter Omega (Ω ω).
Unlike Greek, the Slavic languages had only a single /o/ sound, so Omega was little used compared to the letter On (О о), descended from the Greek letter Omicron. In the older ustav writing Omega was used mainly for its numeric value of 800, and rarely appeared even in Greek words. In later semi-ustav manuscripts it was used for decorative purposes, along with the broad version (Ꙍ ꙍ) as well as the Broad On (Ѻ ѻ).
Modern Church Slavonic has developed strict rules for the use of these letterforms.
Another variation of o is the ornate or beautiful omega, used as an interjection, “O!”. It is represented in Unicode 5.1 by the misnamed character omega with titlo (Ѽ ѽ).
Omega is the name of various medium-format cameras and enlargers. The Simmon Brothers, known for their line of enlargers, built the original Simmon Omega cameras in the United States. These rangefinder cameras took 6x7cm photographs on 120 roll film. Later, Konica manufactured the Koni Omega line. The last models, including the Rapid Omega 200, came from Mamiya. This line had interchangeable lenses, including a 58 (or 60) mm wide-angle, a 90 mm normal lens, a 135 mm portrait lens, and a 180 mm telephoto. A close-up adapter was popular with wedding photographers.
Another line, the Omegaflex, was a twin-lens reflex camera. Its lenses and accessories were not interchangeable with those from the Omega line. The Omegaflex took 6x7 rectangular pictures on 120 roll film.
Backs: The Omegaflex film holder interchanges with the Omega M, 100 (Press 2 in Japan) and 200, and permits mid-roll changes on the Omegaflex, M, and 200. The earlier Koni Omega Rapid (Press in Japan) film holder is not compatible with the above, and does not permit mid-roll changes.
Oficial Spartan is the current ring name of Victor Manuel Montés (born July 29, 1975 in Guerrero, Mexico), who is a Mexican luchador enmascarado, or masked professional wrestler currently working for the Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG) as a part of the Los Oficiales Elite group alongside Oficial Factor and Oficial Rayan. Montés previously worked under a number of other ring names including Omega and Arlequín Rojo, but they are not officially acknowledged as the enmascarado character is promoted as a separate entity from Montés' previous characters as is often the case when a Mexican wrestler adopts a new masked character.
Victor Manuel Montés began his professional wrestling career in 1990 and worked under various enmascarado (masked) characters such as Halcon de Fuego ("Fire Falcon"), Guerrero Atomico ("Atomic Warrior") and Cepillito ("Brush").
"Mad" is a song by American pop/R&B singer Ne-Yo. It is the third single from his album Year of the Gentleman and was produced by Stargate and himself.
The video for the song was directed by Diane Martel. It premiered on AOL on November 25, 2008. The video, shot in black and white, presents a narrative wherein Ne-Yo argues with his girlfriend (played by Faune Chambers). After leaving, in an attempt to save a child from a car accident, someone is fatally hit. At the end of the video, it is revealed that the whole time it has been the ghost of Ne-Yo's character singing, and that it was he who was killed. The video to this song is Part 2 to his song Part of the List.
The music video appears to mirror the 1999 American thriller The Sixth Sense from M. Night Shyamalan, in which Bruce Willis plays a psychologist who is shot by an estranged patient of his. Based on how the film was shot and portrayed, Bruce Willis is shown in many situations as if he is there physically, when in actuality he was murdered by his patient, just as how Ne-Yo appears with his girlfriend, seeming to be there physically and that she is ignoring him due to their earlier argument, when he is actually dead.
Mad1 is a non-essential protein in yeast which has a function in the spindle assembly checkpoint (SAC). This checkpoint monitors chromosome attachment to spindle microtubules and prevents cells from starting anaphase until the spindle is built up. The name Mad refers to the observation that mutant cells are mitotic arrest deficient (MAD) during microtubule depolymerization. Mad1 recruits the anaphase inhibitor Mad2 to unattached kinetochores and is essential for Mad2-Cdc20 complex formation in vivo but not in vitro. In vivo, Mad1 acts as a competitive inhibitor of the Mad2-Cdc20 complex. Mad1 is phosphorylated by Mps1 which then leads together with other activities to the formation of the mitotic checkpoint complex (MCC). Thereby it inhibits the activity of the anaphase-promoting complex/cyclosome (APC/C). Homolog’s of Mad1 are conserved in eukaryotes from yeast to mammals.
In the early 90s, yeast genes were identified which mutations resulted in a defect in mitotic arrest in response to microtubule disassembly (mitotic arrest deficient genes - MAD genes). This cells showed during division no mitotic arrest in the presence of microtubule polymerization inhibitors and were therefore not able to delay cell division. The genes identified included the MAD1, MAD2 and MAD3 genes. They are conserved in all eukaryotes and are involved in a pathway that is active in prometaphase to prevent the premature separation of sister chromatids and constitute the so-called spindle assembly checkpoint(SAC). This checkpoint monitors the status of chromosome attachment to the mitotic spindle and inhibits the metaphase to anaphase transition by preventing the activation of the anaphase-promoting complex/cyclosome (APC/C), and thereby the degradation of cell cycle regulators. Mad1 is in this pathway accumulated at unattached kinetochores and acts as a sensor for unattached kinetochores in this machinery.
Ravi Coltrane (born August 6, 1965 in Long Island, New York) is an American post-bop jazz saxophonist. Co-owner of the record label RKM Music, he has produced artists such as pianist Luis Perdomo, guitarist David Gilmore, and trumpeter Ralph Alessi.
Ravi Coltrane is the son of saxophonist John Coltrane and jazz pianist Alice Coltrane. He is also a cousin of experimental music producer Steven Ellison, aka Flying Lotus. He was raised in Los Angeles, California, and was named after sitar player Ravi Shankar. Coltrane was not yet two years old in 1967 when his father died.
He is a 1983 graduate of El Camino Real High School in Woodland Hills, California. In 1986, he studied music, focusing on the saxophone at the California Institute of the Arts. He has worked extensively with M-Base guru Steve Coleman, a significant influence on Coltrane's own musical conception. Coltrane has played with Geri Allen, Kenny Barron, McCoy Tyner, Pharoah Sanders, Herbie Hancock, Carlos Santana, Stanley Clarke, Branford Marsalis and others.
