The goal was to build a computer system that could simul... |
https://en.wikipedia.org/wiki/Affiliated%20operator | In mathematics, affiliated operators were introduced by Murray and von Neumann in the theory of von Neumann algebras as a technique for using unbounded operators to study modules generated by a single vector. Later Atiyah and Singer showed that index theorems for elliptic operators on closed manifolds with infinite fun... |
https://en.wikipedia.org/wiki/Actinic%20conjunctivitis | Actinic conjunctivitis is an inflammation of the eye contracted from prolonged exposure to actinic (ultraviolet) rays. Symptoms are redness and swelling of the eyes. Most often the condition is caused by prolonged exposure to Klieg lights, therapeutic lamps or acetylene torches. Other names for the condition include... |
https://en.wikipedia.org/wiki/Day-night%20average%20sound%20level | The day-night average sound level (Ldn or DNL) is the average noise level over a 24-hour period. The noise level measurements between the hours of 22:00 and 07:00 are artificially increased by 10 dB before averaging. This noise is weighted to take into account the decrease in community background noise of 10 dB during ... |
https://en.wikipedia.org/wiki/Spherical%20model | The spherical model is a model of ferromagnetism similar to the Ising model, which was solved in 1952 by T. H. Berlin and M. Kac. It has the remarkable property that for linear dimension d greater than four, the critical exponents that govern the behaviour of the system near the critical point are independent of d and ... |
https://en.wikipedia.org/wiki/Crypt%20%28anatomy%29 | Crypts are anatomical structures that are narrow but deep invaginations into a larger structure.
One common type of anatomical crypt is the Crypts of Lieberkühn. However, it is not the only type: some types of tonsils also have crypts. Because these crypts allow external access to the deep portions of the tonsils, t... |
https://en.wikipedia.org/wiki/Hereditarily%20countable%20set | In set theory, a set is called hereditarily countable if it is a countable set of hereditarily countable sets.
Results
The inductive definition above is well-founded and can be expressed in the language of first-order set theory.
Equivalent properties
A set is hereditarily countable if and only if it is countable, an... |
https://en.wikipedia.org/wiki/Berry%20mechanism | The Berry mechanism, or Berry pseudorotation mechanism, is a type of vibration causing molecules of certain geometries to isomerize by exchanging the two axial ligands (see Figure at right) for two of the equatorial ones. It is the most widely accepted mechanism for pseudorotation and most commonly occurs in trigonal b... |
https://en.wikipedia.org/wiki/Pseudorotation | In chemistry, a pseudorotation is a set of intramolecular movements of attached groups (i.e., ligands) on a highly symmetric molecule, leading to a molecule indistinguishable from the initial one. The International Union of Pure and Applied Chemistry (IUPAC) defines a pseudorotation as a "stereoisomerization resulting ... |
https://en.wikipedia.org/wiki/International%20Sanitary%20Conferences | The International Sanitary Conferences were a series of 14 international meetings held in response to growing concerns about human disease epidemics. The first of the Sanitary Conferences was organized by the French Government in 1851 to standardize international quarantine regulations against the spread of cholera, pl... |
https://en.wikipedia.org/wiki/Nerve%20%28category%20theory%29 | In category theory, a discipline within mathematics, the nerve N(C) of a small category C is a simplicial set constructed from the objects and morphisms of C. The geometric realization of this simplicial set is a topological space, called the classifying space of the category C. These closely related objects can provid... |
https://en.wikipedia.org/wiki/Palatine%20nerves | The palatine nerves (descending branches) are distributed to the roof of the mouth, soft palate, tonsil, and lining membrane of the nasal cavity.
Most of their fibers are derived from the sphenopalatine branches of the maxillary nerve.
In older texts, they are usually categorized as three in number: anterior, middle,... |
https://en.wikipedia.org/wiki/Core%20electron | Core electrons are the electrons in an atom that are not valence electrons and do not participate in chemical bonding. The nucleus and the core electrons of an atom form the atomic core. Core electrons are tightly bound to the nucleus. Therefore, unlike valence electrons, core electrons play a secondary role in chemica... |
