Apex may refer to:
Apex (Katy Bashir) is a fictional character appearing in American comic books published by Marvel Comics.
Apex first appeared in issue #1 of the Avengers Arena series as part of the Marvel NOW! event, and was created by Dennis Hopeless and Kev Walker.
Apex is one of sixteen teenagers kidnapped by Arcade who forces them to fight each other to the death in his latest version of Murderworld. She is part of the Braddock Academy group (consisting of Kid Briton, Anachronism, Bloodstone and Nara) which is joined by Death Locket despite death threats from Kid Briton and Nara. Death Locket started bonding with Apex as she introduces her to the rest of the Braddock Academy.
There is discord in the Braddock Academy's ranks as Anachronism and Kid Briton get into an argument. An earthquake then separates Bloodstone and Anachronism from Apex, Nara, Kid Briton, and Death Locket. Death Locket goes dormant as her cybernetics take over and she blasts Nara off a cliff and into the ocean. Kid Briton is enraged by this and tries to kill her until Apex orders him not to, revealing that she knew about his affair with Nara back at the Braddock Academy and that "we're here now and I'm done sharing."
Apex was an experimental radio broadcasting system introduced in the United States in 1934 that used high frequencies between roughly 25 and 42 MHz and wideband AM modulation (as opposed to traditional AM broadcasting's narrowband modulation) to achieve high fidelity sound with less static and distortion than medium wave AM stations in the so-called standard broadcast band (then, 545-1505 kHz) experience. They were called "apex", "skyscraper" or "pinnacle" stations because of the height of the broadcast antennas used.
The Federal Communications Commission thought initially that very high frequency (VHF) radio waves would have a small, discrete range, and would allow two or more stations to broadcast on duplicate frequencies without interfering with each other. But later it was realized that during peaks in the 11-year sunspot cycle even VHF radio waves could reflect from the ionosphere, and Apex station signals could sometimes be heard on the other side of the planet. In October 1937, the FCC made public its allocation plan for VHF radio broadcasting: 75 channels with 40 kHz separation on 41.02 to 43.98 MHz for Apex stations and 16 channels in 30-40 MHz for relay stations. Twenty-five of the 75 channels were reallocated for educational use in 1938.
This is a list of fictional factions in Revelation Space. The human factions are found in the Revelation Space universe, the setting for a series of stories and novels by Welsh author Alastair Reynolds.
Spacefaring humanity is divided among these four main factions. While each of these factions has its roots in the Solar System, they have spread with humans to multiple other star systems. Demarchists controlled most major colony worlds, including Yellowstone, until the introduction of the Melding Plague. Conjoiners inhabited hollowed out asteroids on system peripheries, called Nests, before the move to the central Mother Nest in the Yellowstone system during the Conjoiner-Demarchist war. Ultras prefer living aboard the massive lighthugger ships, and are generally uncomfortable on terrestrial worlds. Skyjacks are comet and asteroid miners.
An ultra-prominent peak, or Ultra for short, is defined as a mountain summit with a topographic prominence of 1,500 metres (4,921 ft) or more. There are approximately 1,515 such peaks on Earth. Some are famous even to non-climbers, such as Mount Everest, Aconcagua, and Denali (the top three by prominence), while others are much more obscure. Some famous peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence.
The term "Ultra" is due to earth scientist Stephen Fry, from his studies of the prominence of peaks in Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least 5,000 ft (1,524 m) of prominence.
Currently, 1,515 Ultras have been identified worldwide: 637 in Asia, 355 in North America, 209 in South America, 119 in Europe (including the Caucasus), 84 in Africa, 69 in Australasia and 39 in Antarctica.
Blue Sky Black Death (abbreviated BSBD) is a production duo based in the San Francisco Bay Area. It consists of Ryan Maguire, better known by his stage name Kingston, and Ian Taggart, better known by his stage name Young God. They are known principally for their hip hop and instrumental music, made with a mixture of live instrumentation and sampling. Their name is "a skydiving phrase alluding to beauty and death."
Kingston and Young God met and began collaborating on music in 2003. Young God, working under the name Rev. Left, began creating beats to rap over, but abandoned rapping and started producing exclusively around 2000. Kingston, working under the name Orphan, began his solo producing career collaborating with rapper Noah23 and the Plague Language collective (to which Young God also contributed production). Kingston entirely produced Noah23's debut album Cytoplasm Pixel in 1999, and the two collaborated closely until Jupiter Sajitarius in 2004, after which they parted ways. In the same year, Kingston worked on projects for Virtuoso's Omnipotent Records. He contributed a number of tracks to Jus Allah's scheduled Omnipotent debut All Fates Have Changed, but the album was shelved. The tracks "Vengeance" and "Drill Sergeant" were later released on BSBD's Dirtnap mixtape, and a number of other beats recorded for the album were bootlegged on The Devil'z Rejects album Necronomicon. One Kingston beat, "Supreme (Black God's Remix)" was included on the Babygrande Records release of All Fates Have Changed in 2005.
