During his professional MMA career starting in 2004 , Hardy fought in various promotions such as Cage Force and Cage Warriors before signing a contract with the Ultimate Fighting Championship in 2008 . His nickname , '' The Outlaw '' , comes from the screen name he used on the Cage Warrior forum when he was looking for training partners after a disagreement with a coach leading to his former training partners being forbidden to work with him . - Beirut ("") is the capital and largest city of Lebanon. No recent population census has been done but in 2007 estimates ranged from slightly more than 1million to slightly less than 2million as part of Greater Beirut. Located on a peninsula at the midpoint of Lebanon's Mediterranean coast, Beirut is the country's largest and main seaport. - Las Vegas (Spanish for "The Meadows"), officially the City of Las Vegas and often known simply as Vegas, is the 28th-most populated city in the United States, the most populated city in the state of Nevada, and the county seat of Clark County. The city anchors the Las Vegas Valley metropolitan area and is the largest city within the greater Mojave Desert. Las Vegas is an internationally renowned major resort city known primarily for its gambling, shopping, fine dining, entertainment, and nightlife. It is the leading financial, commercial, and cultural center for Nevada. - London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly. - The Ultimate Fighting Championship (UFC) is an American mixed martial arts promotion company, a subsidiary of the parent company William Morris Endeavor, based in Las Vegas, Nevada.

Based in the United States, the UFC produces events worldwide that showcase ten weight divisions and abide by the Unified Rules of Mixed Martial Arts. The UFC has held over 300 events to date. Dana White serves as the president of the UFC. Given the paragraphs above, decide what entity has the relation 'residence' with 'las vegas valley'.

Problem: Information: - In mathematics, the Menger sponge (also known as the Menger universal curve) is a fractal curve. It is a three-dimensional generalization of the Cantor set and Sierpinski carpet, though it is slightly different from a Sierpinski sponge. It was first described by Karl Menger in 1926, in his studies of the concept of topological dimension. - IMAGE (from Imager for Magnetopause-to-Aurora Global Exploration), or Explorer 78, was a NASA MIDEX mission that studied the global response of the Earth's magnetosphere to changes in the solar wind. It was launched March 25, 2000 by a Delta II rocket from Vandenberg AFB and ceased operations in December 2005. - In information technology, lossy compression or irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storage, handling, and transmitting content. Different versions of the photo of the cat above show how higher degrees of approximation create coarser images as more details are removed. This is opposed to lossless data compression (reversible data compression) which does not degrade the data. The amount of data reduction possible using lossy compression is often much higher than through lossless techniques. - The Mandelbrot set is the set of complex numbers "c" for which the function formula_1 does not diverge when iterated from formula_2, i.e., for which the sequence formula_3, formula_4, etc., remains bounded in absolute value. The set is closely related to the idea of Julia sets, which produce similarly complex shapes. Its definition and name are due to Adrien Douady, in tribute to the mathematician Benoit Mandelbrot. - A fractal is a mathematical set that exhibits a repeating pattern displayed at every scale. It is also known as expanding symmetry or evolving symmetry. If the replication is exactly the same at every scale, it is called a self-similar pattern. An example of this is the Menger Sponge. Fractals can also be nearly the same at different levels. This latter pattern is illustrated in small magnifications of the Mandelbrot set. Fractals also include the idea of a detailed pattern that repeats itself. - Fractal compression is a lossy compression method for digital images , based on fractals . The method is best suited for textures and natural images , relying on the fact that parts of an image often resemble other parts of the same image . Fractal algorithms convert these parts into mathematical data called '' fractal codes '' which are used to recreate the encoded image . Given the paragraphs above, decide what entity has the relation 'subclass of' with 'data compression'.
