SOS box

SOS box is the region in the promoter of various genes to which the LexA repressor binds to repress the transcription of SOS-induced proteins. This occurs in the absence of DNA damage. In the presence of DNA damage the binding of LexA is inactivated by the RecA activator. SOS boxes differ in DNA sequences and binding affinity towards LexA from organism to organism. Furthermore, SOS boxes may be present in a dual fashion, which indicates that more than one SOS box can be within the same promoter.

Klinik

Klinik, (sometimes called The Klinik), is an industrial music band from Belgium, originally formed around 1982 by electro-synthpop practitioner Marc Verhaeghen, who is the only constant member.

History

Marc Verhaeghen originally formed Klinik in the early-to-mid 1980s; the exact date varies depending on the source. The group is normally described as one of the most influential Belgian industrial bands in history.

In 1985, Verhaeghen joined forces with two other bands, Absolute Body Control (with Dirk Ivens and Eric van Wonterghem), and "The Maniacs" (Sandy Nys) to form one "super group" "Absolute Controlled Clinical Maniacs". This rather unwieldy name was soon dropped in favour of the shorter name "The Klinik". Nys soon left the band to form "Hybryds", followed in 1987 by van Wonterghem, leaving The Klinik as the "classic" duo of Dirk Ivens and Marc Verhaeghen.

The Klinik soon made a name for themselves with their cold and harsh EBM sound and their live shows, where both Ivens and Verhaeghen performed with their heads wrapped in gauze, wearing long black leather coats. Ivens' hissing vocals and minimalist lyrics were complemented by Verhaeghen's synthesizer skills and distorted trombone playing. This however, did not last forever; after Time, an album neither member was fully pleased with, musical differences became too great, and they decided to go their separate ways. In a 2013 interview, Ivens said the due were moving in different directions musically, and that compromise between only two members was challenging.

Hi-Riser (automobile)

Hi-Risers are a type of highly customized automobile, typically a traditional, full-size, body on frame, V8 powered, rear wheel drive American-built sedan modified by significantly increasing the ground clearance and adding large-diameter wheels with low-profile tires. Depending on the model and style of body, autos customized in this manner can be labeled "donk," "box," or "bubble."

Hi-risers originally grew out of the Dirty South subculture, but the trend has spread across the United States. Vehicles customized in the hi-riser style are distinguished by their oversized (even disproportionate) wheels, ranging from 20 inches to 30 inches or more in diameter (largest being 50 inch), as well as fanciful custom paint-jobs and expensive audio equipment. Suspension modifications similar to those employed on lifted pickup trucks are made to give adequate clearance for the large wheels. Often the suspension is modified so the front end sits slightly higher than the rear end, giving the car a swaggering appearance. Because of the exaggerated look gained from installing a lifted suspension and enormous wheels, donks are also known as "hi-risers" or "sky-scrapers."

Hyperrectangle

In geometry, an n-orthotope (also called a hyperrectangle or a box) is the generalization of a rectangle for higher dimensions, formally defined as the Cartesian product of intervals.

Types

A three-dimensional orthotope is also called a right rectangular prism, rectangular cuboid, or rectangular parallelepiped.

A special case of an n-orthotope, where all edges are equal length, is the n-cube.

By analogy, the term "hyperrectangle" or "box" refers to Cartesian products of orthogonal intervals of other kinds, such as ranges of keys in database theory or ranges of integers, rather than real numbers.

Dual polytope

The dual polytope of an n-orthotope has been variously called a rectangular n-orthoplex, rhombic n-fusil, or n-lozenge. It is constructed by 2n points located in the center of the orthotope rectangular faces.

An n-fusil's Schläfli symbol can be represented by a sum of n orthogonal line segments: { } + { } + ... + { }.

A 1-fusil is a line segment. A 2-fusil is a rhombus. Its plane cross selections in all pairs of axes are rhombi.

21st Special Operations Squadron

The 21st Special Operations Squadron is a unit within the 352d Special Operations Group (352 SOG), United States Air Force, United States European Command, and was based at Royal Air Force base RAF Mildenhall in Suffolk, eastern England.

Mission

The 21st Special Operations Squadron, which fell under the 352nd Special Operations Group, RAF Mildenhall, UK, was inactivated on 31 October 2007 with the inactivation ceremony taking place at RAF Mildenhall, UK on 9 October temporarily ending the Air Force Special Operations vertical lift mission in Europe.

The inactivation of the Dust Devils was the first step in preparation for the arrival of the CV-22 tilt-rotor aircraft.

The 21st Special Operations Squadron's mission consisted of day or night, all-weather, low-level penetration of denied territory to provide infiltration, exfiltration, resupply, or fire support for elite air, ground, and naval forces. The unique capabilities of the MH-53J permitted the squadron to operate from unprepared landing zones.

8th Special Operations Squadron

The 8th Special Operations Squadron (8 SOS) is a squadron of the United States Air Force. It is assigned to the 1st Special Operations Wing, Air Force Special Operations Command, stationed at Hurlburt Field, Florida. The squadron is equipped with the CV-22 Osprey in support of special operations.

The 8 SOS is one of the oldest units in the United States Air Force, being organized as the 8th Aero Squadron on 21 June 1917 at Kelly Field, Texas. The squadron deployed to France and fought on the Western Front during World War I, equipped with United States-built Dayton-Wright DH-4, being used as reconnaissance aircraft.

During World War II, the squadron fought in the Southwest Pacific Area with Fifth Air Force as an attack and later B-25 Mitchell medium bomber squadron. During the Cold War, it fought in the Korean War with B-26 Invader medium bombers and Vietnam War as a B-57 Canberra medium bomber and later as an Air Commando squadron with A-37 Dragonfly counter-insurgency aircraft.

5 Seconds of Summer

5 Seconds of Summer (commonly abbreviated as 5SOS) are an Australian rock band from Sydney that formed in 2011. The group were originally YouTube celebrities, posting videos of themselves covering songs from various artists during 2011 and early 2012. They rose to international fame while touring with One Direction on the Take Me Home Tour.

The group have been referred to as a boy band in the media, though the members reject this description. In early 2014, the band released "She Looks So Perfect" worldwide as its debut single, which topped the charts in Australia, New Zealand, Ireland and the United Kingdom. The self-titled debut studio album was released in June 2014, which peaked #1 in 11 countries, and followed by a live album titled LiveSOS. The band released their second album Sounds Good Feels Good in 2015.

History

2011–12: Origin and debut

5 Seconds of Summer began in 2011 when Luke Hemmings, Michael Clifford and Calum Hood, who all attended Norwest Christian College, started posting videos of themselves performing covers of popular songs together on Hemmings' YouTube channel. Hemmings' first video, a cover of Mike Posner's "Please Don't Go", was posted on 3 February 2011. Their cover of Chris Brown's "Next to You" received over 600,000 hits. In December 2011, they were joined by drummer Ashton Irwin, and the four-man line up was completed.
