https://en.wikipedia.org/wiki/Oxyphil%20cell%20%28parathyroid%29 | Parathyroid oxyphil cells are one out of the two types of cells found in the parathyroid gland, the other being parathyroid chief cell. Oxyphil cells are only found in a select few number of species and humans are one of them.
These cells can be found in clusters in the center of the section and at the periphery. Ox... |
https://en.wikipedia.org/wiki/Sertoli%20cell | Sertoli cells are a type of sustentacular "nurse" cell found in human testes which contribute to the process of spermatogenesis (the production of sperm) as a structural component of the seminiferous tubules. They are activated by follicle-stimulating hormone (FSH) secreted by the adenohypophysis and express FSH recept... |
https://en.wikipedia.org/wiki/Kinemage | A kinemage (short for kinetic image) is an interactive graphic scientific illustration. It often is used to visualize molecules, especially proteins although it can also represent other types of 3-dimensional data (such as geometric figures, social networks, or tetrahedra of RNA base composition). The kinemage system ... |
https://en.wikipedia.org/wiki/Studentized%20residual | In statistics, a studentized residual is the quotient resulting from the division of a residual by an estimate of its standard deviation. It is a form of a Student's t-statistic, with the estimate of error varying between points.
This is an important technique in the detection of outliers. It is among several named in... |
https://en.wikipedia.org/wiki/Destroyer%20escort | Destroyer escort (DE) was the United States Navy mid-20th-century classification for a warship designed with the endurance necessary to escort mid-ocean convoys of merchant marine ships.
Development of the destroyer escort was promoted by the British need in World War II for anti-submarine ships that could operate in... |
https://en.wikipedia.org/wiki/Gelfond%E2%80%93Schneider%20theorem | In mathematics, the Gelfond–Schneider theorem establishes the transcendence of a large class of numbers.
History
It was originally proved independently in 1934 by Aleksandr Gelfond and Theodor Schneider.
Statement
If a and b are complex algebraic numbers with a ≠ 0, 1, and b not rational, then any value of ab is a... |
https://en.wikipedia.org/wiki/Duality%20%28mathematics%29 | In mathematics, a duality translates concepts, theorems or mathematical structures into other concepts, theorems or structures, in a one-to-one fashion, often (but not always) by means of an involution operation: if the dual of is , then the dual of is . Such involutions sometimes have fixed points, so that the dual ... |
https://en.wikipedia.org/wiki/Kinesin | A kinesin is a protein belonging to a class of motor proteins found in eukaryotic cells. Kinesins move along microtubule (MT) filaments and are powered by the hydrolysis of adenosine triphosphate (ATP) (thus kinesins are ATPases, a type of enzyme). The active movement of kinesins supports several cellular functions inc... |
https://en.wikipedia.org/wiki/Dynein | Dyneins are a family of cytoskeletal motor proteins that move along microtubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargos, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella. All of th... |
https://en.wikipedia.org/wiki/Consistency%20%28statistics%29 | In statistics, consistency of procedures, such as computing confidence intervals or conducting hypothesis tests, is a desired property of their behaviour as the number of items in the data set to which they are applied increases indefinitely. In particular, consistency requires that the outcome of the procedure with un... |
https://en.wikipedia.org/wiki/Felsite | Felsite is a very fine-grained volcanic rock that may or may not contain larger crystals. Felsite is a field term for a light-colored rock that typically requires petrographic examination or chemical analysis for more precise definition. Color is generally white through light gray, or red to tan and may include any co... |
https://en.wikipedia.org/wiki/G.%20I.%20Taylor | Sir Geoffrey Ingram Taylor OM FRS FRSE (7 March 1886 – 27 June 1975) was a British physicist and mathematician, who made contributions to fluid dynamics and wave theory.
Early life and education
Taylor was born in St. John's Wood, London. His father, Edward Ingram Taylor, was an artist, and his mother, Margaret Boole,... |
