Pulse-code modulation

Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, Compact Discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps.

Linear pulse-code modulation (LPCM) is a specific type of PCM where the quantization levels are linearly uniform. This is in contrast to PCM encodings where quantization levels vary as a function of amplitude (as with the A-law algorithm or the μ-law algorithm). Though PCM is a more general term, it is often used to describe data encoded as LPCM.

A PCM stream has two basic properties that determine the stream's fidelity to the original analog signal: the sampling rate, which is the number of times per second that samples are taken; and the bit depth, which determines the number of possible digital values that can be used to represent each sample.

PCM1

Pericentriolar material 1, also known as PCM1, is a protein which in humans is encoded by the PCM1 gene.

Function

The PCM1 protein was originally identified by virtue of its distinct cell cycle-dependent association with the centrosome complex and microtubules. The protein appears to associate with the centrosome complex during the cell cycle. Dissociation occurs during mitosis when PCM1 is dispersed throughout the cell. Immunolabeling studies performed found that PCM1 was present in centriolar satellites and in electron dense granules between 70 and 100 nm in diameter. These were originally thought to be scattered only around the centrosomes, but further studies proved that PCM1 was also found throughout the cytoplasm.

PCM1 was shown to be essential for cell division because PCM1 antibodies cause cell-cycle arrest when microinjected into fertilized murine eggs. Targeting of centrin, pericentrin and ninein was also dramatically reduced after PCM1 depletion using siRNA, overexpression of PCM1 deletion mutants and PCM1 antibody microinjection. As a result of this depletion, the radial organization of the microtubules was found to be disrupted, but did not appear to effect microtubule nucleation.

Fight+

Fight+ was a European combat sports TV channel founded by David McConachie and Steffen Tangstad.

Fight+ showed movies, documentaries, classic and exclusive matches, training and educational programming and news. The plan was for Fight+ to become available all over Europe as fast as possible.

Fight+ closed down on December 11, 2006 according to CanalDigital website. According to the same website the channel is closing because there hasn't been enough interest from customers of CanalDigital, and they've also had problems finding new investors.

Countries where Fight+ was available

Programming

The channel broadcast programming on amateur and professional wrestling; boxing, kickboxing, Muay Thai, Mixed martial arts, Kung-Fu, judo and karate; cagefighting, bodybuilding, and strength athletics.

Combat

Combat or fighting is a purposeful violent conflict meant to weaken, establish dominance over, or kill the opposition, or to drive the opposition away from a location where it is not wanted or needed.

The term combat (French for fight) typically refers to armed conflict between opposing military forces in warfare, whereas the more general term "fighting" can refer to any physical or verbal conflict between individuals or nations. Combat violence can be unilateral, whereas fighting implies at least a defensive reaction. A large-scale fight is known as a battle. A verbal fight is commonly known as an argument.

Background

Combat may take place under a specific set of rules or be unregulated. Examples of rules include the Geneva Conventions (covering the treatment of people in war), medieval chivalry, the Marquess of Queensberry rules (covering boxing) and several forms of combat sports.

Combat in warfare involves two or more opposing military organizations, usually fighting for nations at war (although guerrilla warfare and suppression of insurgencies can fall outside this definition). Warfare falls under the laws of war, which govern its purposes and conduct, and protect the rights of combatants and non-combatants.

Fight (Doro album)

Fight is the eighth studio album of the German female hard rock singer Doro Pesch. It was released worldwide in 2002 by SPV/Steamhammer.

Fight is the first Doro album since Force Majeure to be produced with a strong contribution from the members of the band that accompanied the German singer on her tours. Nick Douglas, Joe Taylor and Johnny Dee had toured with Doro for more than ten years, while Oliver Palotai replaced Mario Parillo after his demise in 2001.

The songs of the album are the usual mix of aggressive metal and soft ballads, with a distinctive rawer sound than in previous albums. At this time Doro tried some versions of the songs in languages different form English or German. What remains of these recordings are the chorus of "Salvaje" in Spanish and the chorus of the single's b-side "Tourjour pour Gasner" in French. The list of musicians sees the contribution of various guests: Type O Negative vocalist Peter Steele, Savatage guitarist Chris Caffery, former Plasmatics bassist Jean Beauvoir, veteran composer Russ Ballard and usual collaborators Chris Lietz, Jürgen Engler and Andreas Bruhn. The title track was used by German boxer Regina Halmich to introduce her performances, while "Always Live to Win" became the official theme of Rhein Fire NFL Europe football team. "Legends Never Die" is a cover of a song performed by Wendy O. Williams on her album WOW of 1984.
