Homoscedasticity and heteroscedasticityIn statistics, a sequence (or a vector) of random variables is homoscedastic (ˌhoʊmoʊskəˈdæstɪk) if all its random variables have the same finite variance; this is also known as homogeneity of variance. The complementary notion is called heteroscedasticity, also known as heterogeneity of variance. The spellings homoskedasticity and heteroskedasticity are also frequently used.
AndreaAndrea is a given name which is common worldwide for both males and females, cognate to Andreas, Andrej and Andrew. The name derives from the Greek word ἀνήρ (anēr), genitive ἀνδρός (andrós), that refers to man as opposed to woman (whereas man in the sense of human being is ἄνθρωπος, ánthropos). The original male Greek name, Andréas, represents the hypocoristic, with endearment functions, of male Greek names composed with the andr- prefix, like Androgeos (man of the earth), Androcles (man of glory), Andronikos (man of victory).
Ursid hybridAn ursid hybrid is an animal with parents from two different species or subspecies of the bear family (Ursidae). Species and subspecies of bear known to have produced offspring with another bear species or subspecies include American black bears, grizzly bears, and polar bears, all of which are members of the genus Ursus. Bears not included in Ursus, such as the giant panda, are expected to be unable to produce hybrids with other bears. The giant panda bear belongs to the genus Ailuropoda.
Noble gasThe noble gases (historically also the inert gases; sometimes referred to as aerogens) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). Oganesson (Og) is a synthetically produced highly radioactive element.
St Andrew's Church, Andreas, Isle of ManSt Andrew's Church, Andreas, is a Church of England parish church in Andreas, Isle of Man. The church is administered by the Diocese of Sodor and Man. It is generally supposed that Christianity was introduced to the Isle of Man by St Patrick about the middle part of the 5th Century and that St German was appointed as the first Bishop of Man. Under the influence of St Patrick and what is referred to as his "Romish missionaries," the Isle of Man saw the erection of a series of small chapels throughout the Island.
Plug-in hybridA plug-in hybrid electric vehicle (PHEV) is a hybrid electric vehicle whose battery pack can be recharged by plugging a charging cable into an external electric power source, in addition to internally by its on-board internal combustion engine-powered generator. Most PHEVs are passenger cars, but there are also PHEV versions of sports cars, commercial vehicles and vans, utility trucks, buses, trains, motorcycles, mopeds, and even military vehicles.
ElectronThe electron (_Electron or _beta-) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, ħ.
Relative densityRelative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at ); for gases, the reference is air at room temperature (). The term "relative density" (often abbreviated r.d. or RD) is often preferred in scientific usage, whereas the term "specific gravity" is deprecated.
San Andreas (film)San Andreas is a 2015 American disaster film directed by Brad Peyton and written by Carlton Cuse, with Andre Fabrizio and Jeremy Passmore receiving story credit. The film stars Dwayne Johnson, in the lead role, Carla Gugino, Alexandra Daddario, Ioan Gruffudd, Archie Panjabi and Paul Giamatti. Its plot centers on a massive earthquake caused by the San Andreas Fault, devastating the West Coast of the United States. Principal photography of the film started on April 22, 2014, in Queensland, Australia, and wrapped up on July 28 in San Francisco.
Quantum chemistryQuantum chemistry, also called molecular quantum mechanics, is a branch of physical chemistry focused on the application of quantum mechanics to chemical systems, particularly towards the quantum-mechanical calculation of electronic contributions to physical and chemical properties of molecules, materials, and solutions at the atomic level. These calculations include systematically applied approximations intended to make calculations computationally feasible while still capturing as much information about important contributions to the computed wave functions as well as to observable properties such as structures, spectra, and thermodynamic properties.
