Graph center
The center (or Jordan center) of a graph is the set of all vertices of minimum eccentricity, that is, the set of all vertices A where the greatest distance d(A,B) to other vertices B is minimal. Equivalently, it is the set of vertices with eccentricity equal to the graph's radius. Thus vertices in the center (central points) minimize the maximal distance from other points in the graph.
Finding the center of a graph is useful in facility location problems where the goal is to minimize the worst-case distance to the facility. For example, placing a hospital at a central point reduces the longest distance the ambulance has to travel.
The concept of the center of a graph is related to the closeness centrality measure in social network analysis, which is the reciprocal of the mean of the distances d(A,B).

Premise
In 2048, the uncontrollable evolution of science and technology has caused crime rates to rise an astounding 400%. To combat this, the overwhelmed police force has implemented a new policy: every human police officer is paired with a lifelike combat-model android.
John Kennex (Karl Urban), a troubled detective, has a reason to hate these new robot partners. Almost two years previously, Kennex and his squad were raiding the hideout of a violent gang known as InSyndicate, but ended up being ambushed and outgunned. Kennex tried to save his badly injured partner, but the accompanying logic-based android officer abandoned them both because the wounded man's chances of survival were low and it wouldn't have been "logical" to save him. An explosion then took off Kennex's leg and killed his partner.
Skin (Rihanna song)
"Skin" is a song by Barbadian recording artist Rihanna from her fifth studio album, Loud (2010). The song was written by Kenneth Coby and Ursula Yancy, with production helmed by Soundz. Musically, "Skin" is influenced by pop, dance-pop and dubstep genres, whilst lyrically, the song is about being in a relationship with someone and only wanting to feel their skin close to the protagonists. "Skin" received generally positive reviews from critics, as part of their overall review of Loud, praising "Skin"'s compositions as well as Rihanna's sensual vocal performance. The song was included on the set list of the Loud Tour (2011), where Rihanna retrieves a man or woman from the audience near the end of the song, and performs a lap-dance whilst on an elevated platform. "Skin" was also used in Rihanna's advertisement campaign for Armani Jeans.
Background and composition
Ray of Light
Ray of Light is the seventh studio album by American singer Madonna, released on February 22, 1998 by Maverick Records. After giving birth to her first child, Lourdes, Madonna started working on the album with producers Babyface and Patrick Leonard. Following failed sessions with them, Madonna pursued a new musical direction with English producer William Orbit. The recording took place over four months and experienced problems with Orbit's hardware Pro Tools arrangement, which would break down, and recording would have to be delayed until they could be repaired.
A major departure from her previous work, Ray of Light is an electronica record which incorporates several genres, including techno, trip hop, drum and bass, ambient, rock, and classical music. Vocally, the album saw Madonna sing with greater breadth and a fuller tone. Mystical themes are also strongly present in both lyrics and music as a result of Madonna embracing Kabbalah, her study of Hinduism and Buddhism, as well as her daily practice of Hatha Yoga.
