Penis

A penis (plural penises or penes /-niːz/) is the primary sexual organ that male and hermaphrodite animals use to inseminate sexually receptive mates (usually females and hermaphrodites respectively) during copulation. Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species, and in those species in which the male does bear a so-called penis, the penes in the various species are not necessarily homologous. For example, the penis of a mammal is at most analogous to the penis of a male insect or barnacle.

The term penis applies to many intromittent organs, but not to all; for example the intromittent organ of most cephalopoda is the hectocotylus, a specialised arm, and male spiders use their pedipalps. Even within the Vertebrata there are morphological variants with specific terminology, such as hemipenes.

In most species of animals in which there is an organ that might reasonably be described as a penis, it has no major function other than intromission, or at least conveying the sperm to the female, but in the placental mammals the penis bears the distal part of the urethra, which discharges both urine during urination and semen during copulation.

Chicken (game)

The game of chicken, also known as the hawk-dove game or snowdrift game, is an influential model of conflict for two players in game theory. The principle of the game is that while each player prefers not to yield to the other, the worst possible outcome occurs when both players do not yield.

The name "chicken" has its origins in a game in which two drivers drive towards each other on a collision course: one must swerve, or both may die in the crash, but if one driver swerves and the other does not, the one who swerved will be called a "chicken," meaning a coward; this terminology is most prevalent in political science and economics. The name "Hawk-Dove" refers to a situation in which there is a competition for a shared resource and the contestants can choose either conciliation or conflict; this terminology is most commonly used in biology and evolutionary game theory. From a game-theoretic point of view, "chicken" and "hawk-dove" are identical; the different names stem from parallel development of the basic principles in different research areas. The game has also been used to describe the mutual assured destruction of nuclear warfare, especially the sort of brinkmanship involved in the Cuban Missile Crisis.

Fade (lighting)

In stage lighting, a fade is a gradual increase or decrease of the intensity of light projected onto the stage. The term fade-in refers to gradually changing the lighting level from complete darkness to a predetermined lighting level. A fade-out (also known as fade-to-black) refers to gradually decreasing the intensity of light until none is shining on the stage. A crossfade is when lighting levels are gradually altered from one setting to another. A fade-in is sometimes called a build, and where this terminology is used, a fade is understood to be a fade-out.

Increasing lighting intensities that are not black is referred to as a fade-up. Similarly, decreasing lighting intensities to a level above black is referred to as a fade-down.

Cross-fades are accomplished by executing fade-ups and/or fade-downs. In nearly all theatrical lighting designs, multiple lighting instruments are used to illuminate the stage at any one time. A cue refers to the recorded state of illumination for the entire stage at that time. The intensity of the lighting instruments are often altered with a single crossfade, altering the lighting state of the stage.

The Life of Pablo

The Life of Pablo is the seventh studio album by American recording artist Kanye West. It was released by GOOD Music and Def Jam Recordings on February 14, 2016. The album was initially available exclusively through the streaming service Tidal, following a lengthy series of delays in its recording and finalization. Recording of the album dated back to recording sessions for West's fifth album, My Beautiful Dark Twisted Fantasy (2010), and took place in various locations.

Background

West began working on his seventh solo album in November 2013. The album was originally titled So Help Me God and slated for a 2014 release. This version of the album, which never materialized, included several tracks which were released such as "God Level" (released as part of an Adidas World Cup promo), "Tell Your Friends" (later given to The Weeknd), "3500" (given to Travis Scott), "All Day" and "Only One". In February 2015, the only tracks from this version appearing to make the final cut for The Life of Pablo were "Famous" (formerly titled "Nina Chop") and "Wolves", which West performed on Saturday Night Live's 40th anniversary episode, with American recording artists Sia and Vic Mensa.

Rap GTP-binding protein

Rap GTP-binding protein also known as Ras-related proteins or simply RAP is a type of small GTPase, similar in structure to Ras.

These proteins share approximately 50% amino acid identity with the classical RAS proteins and have numerous structural features in common. The most striking difference between RAP proteins and RAS proteins resides in their 61st amino acid: glutamine in RAS is replaced by threonine in RAP proteins. RAP counteracts the mitogenic function of RAS because it can interact with RAS GAPs and RAF in a competitive manner.
