https://en.wikipedia.org/wiki/Endothelial%20stem%20cell
Endothelial stem cells (ESCs) are one of three types of stem cells found in bone marrow. They are multipotent, which describes the ability to give rise to many cell types, whereas a pluripotent stem cell can give rise to all types. ESCs have the characteristic properties of a stem cell: self-renewal and differentiation. These parent stem cells, ESCs, give rise to progenitor cells, which are intermediate stem cells that lose potency. Progenitor stem cells are committed to differentiating along a particular cell developmental pathway. ESCs will eventually produce endothelial cells (ECs), which create the thin-walled endothelium that lines the inner surface of blood vessels and lymphatic vessels. The lymphatic vessels include things such as arteries and veins. Endothelial cells can be found throughout the whole vascular system and they also play a vital role in the movement of white blood cells Development ECs were first thought to arise from extraembryonic tissues because blood vessels were observed in the avian and mammalian embryos. However, after histological analysis, it was seen that ECs were found just in the embryo. This meant that blood vessels come from an intraembryonic source, the mesoderm. Since these cells come from the mesoderm, it can become a wide variety of different things found in many different parts of the body. Role of insulin-like growth factors in endothelium differentiation ECs derived from stem cells are the beginning of vasculogenesis. Vasculogenes
https://en.wikipedia.org/wiki/Eukaryotic%20chromosome%20structure
Eukaryotic chromosome structure refers to the levels of packaging from raw DNA molecules to the chromosomal structures seen during metaphase in mitosis or meiosis. Chromosomes contain long strands of DNA containing genetic information. Compared to prokaryotic chromosomes, eukaryotic chromosomes are much larger in size and are linear chromosomes. Eukaryotic chromosomes are also stored in the cell nucleus, while chromosomes of prokaryotic cells are not stored in a nucleus. Eukaryotic chromosomes require a higher level of packaging to condense the DNA molecules into the cell nucleus because of the larger amount of DNA. This level of packaging includes the wrapping of DNA around proteins called histones in order to form condensed nucleosomes. History The double helix was discovered in 1953 by James Watson and Francis Crick. Other researchers made very important, but unconnected findings about the composition of DNA. Ultimately it was Watson and Crick who put all of these findings together to come up with a model for DNA. Later, chemist Alexander Todd determined that the backbone of a DNA molecule contained repeating phosphate and deoxyribose sugar groups. The biochemist Erwin Chargaff found that adenine and thymine always paired while cytosine and guanine always paired. High resolution X-ray images of DNA that were obtained by Maurice Wilkins and Rosalind Franklin suggested a helical, or corkscrew like shape. Some of the first scientists to recognize the structures now known as
https://en.wikipedia.org/wiki/Skin%20infection
A skin infection is an infection of the skin in humans and other animals, that can also affect the associated soft tissues such as loose connective tissue and mucous membranes. They comprise a category of infections termed skin and skin structure infections (SSSIs), or skin and soft tissue infections (SSTIs), and acute bacterial SSSIs (ABSSSIs). They are distinguished from dermatitis (inflammation of the skin), although skin infections can result in skin inflammation. Causes Bacterial Bacterial skin infections affected about 155 million people and cellulitis occurred in about 600 million people in 2013. Bacterial skin infections include: Cellulitis, a diffuse inflammation of connective tissue with severe inflammation of dermal and subcutaneous layers of the skin. Further, cellulitis can be classified based into purulent and non-purulent cellulitis, based on the most likely causative agent and the symptoms presentation. Purulent cellulitis is often caused by Staphylococcus aureus, including both methicillin-sensitive (MSSA) and methicillin-resistant S. aureus (MRSA). Non-purulent cellulitis is most often associated with group A beta-hemolytic streptococci, such as Streptococcus pyogenes. In rare cases, the infection can progress into necrotizing fasciitis, a serious and potentially fatal infection. Erysipelas, a bacterial infection which primarily affects superficial dermis, and often involves superficial lymphatics. Unlike cellulitis, it does not affect deeper layers of

In measure theory and probability, the monotone class theorem connects monotone classes and -algebras. The theorem says that the smallest monotone class containing an algebra of sets is precisely the smallest -algebra containing  It is used as a type of transfinite induction to prove many other theorems, such as Fubini's theorem. Definition of a monotone class A is a family (i.e. class) of sets that is closed under countable monotone unions and also under countable monotone intersections. Explicitly, this means has the following properties: if and then and if and then Monotone class theorem for sets Monotone class theorem for functions Proof The following argument originates in Rick Durrett's Probability: Theory and Examples. Results and applications As a corollary, if is a ring of sets, then the smallest monotone class containing it coincides with the -ring of By invoking this theorem, one can use monotone classes to help verify that a certain collection of subsets is a -algebra. The monotone class theorem for functions can be a powerful tool that allows statements about particularly simple classes of functions to be generalized to arbitrary bounded and measurable functions.

https://en.wikipedia.org/wiki/Importer%20%28computing%29
An importer is a software application that reads in a data file or metadata information in one format and converts it to another format via special algorithms (such as filters). An importer often is not an entire program by itself, but an extension to another program, implemented as a plug-in. When implemented in this way, the importer reads the data from the file and converts it into the hosting application's native format. For example, the data file for a 3D model may be written from a modeler, such as 3D Studio Max. A game developer may then want to use that model in their game's editor. An importer, part of the editor, may read in the 3D Studio Max model and convert it to the game's native format so it can be used in game levels. Importers are important tools in the video game industry. A plug-in or application that does the converse of an importer is called an exporter.

https://en.wikipedia.org/wiki/Exporter%20%28computing%29
An exporter is a software application that writes out a data file in a format different from its native format. It does this via special algorithms (such as filters). An exporter often is not an entire program by itself, but an extension to another program, implemented as a plug-in. When implemented in this way, the exporter converts the hosting application's native format into the desired format and writes it to the file. For example, a 3D model may be written with a modeler, such as 3D Studio Max. A game developer may want to use that model in its game, but uses a custom format that is different from 3D Studio Max's native format. Using the exporter, the model can be saved in the developer's native format and then read into the game (or a tool) without any extra conversion. Using exporters, game tools can also export from their native format into formats for other applications (such as the modeler or a paint program, such as Photoshop). Exporters are important tools in the video game industry. A plug-in or application that does the converse of an exporter is called an importer. Importers and exporters are often used in conjunction with one another in many software development environments. Video game development
https://en.wikipedia.org/wiki/Circumscriptional%20name
In biological classification, circumscriptional names are taxon names that are not ruled by ICZN and are defined by the particular set of members included. Circumscriptional names are used mainly for taxa above family-group level (e. g. order or class), but can be also used for taxa of any ranks, as well as for rank-less taxa. Non-typified names other than those of the genus- or species-group constitute the majority of generally accepted names of taxa higher than superfamily. The ICZN regulates names of taxa up to family group rank (i. e. superfamily). There are no generally accepted rules of naming higher taxa (orders, classes, phyla, etc.). Under the approach of circumscription-based (circumscriptional) nomenclatures, a circumscriptional name is associated with a certain circumscription of a taxon without regard of its rank or position. Some authors advocate introducing a mandatory standardized typified nomenclature of higher taxa. They suggest all names of higher taxa to be derived in the same manner as family-group names, i.e. by modifying names of type genera with endings to reflect the rank. There is no consensus on what such higher rank endings should be. A number of established practices exist as to the use of typified names of higher taxa, depending on animal group.

https://en.wikipedia.org/wiki/Liquid-crystal%20polymer
Liquid crystal polymers (LCPs) are polymers with the property of liquid crystal, usually containing aromatic rings as mesogens. Despite uncrosslinked LCPs, polymeric materials like liquid crystal elastomers (LCEs) and liquid crystal networks (LCNs) can exhibit liquid crystallinity as well. They are both crosslinked LCPs but have different cross link density. They are widely used in the digital display market. In addition, LCPs have unique properties like thermal actuation, anisotropic swelling, and soft elasticity. Therefore, they can be good actuators and sensors. One of the most famous and classical applications for LCPs is Kevlar, a strong but light fiber with wide applications, notably bulletproof vests. Background Liquid crystallinity in polymers may occur either by dissolving a polymer in a solvent (lyotropic liquid-crystal polymers) or by heating a polymer above its glass or melting transition point (thermotropic liquid-crystal polymers). Liquid-crystal polymers are present in melted/liquid or solid form. In solid form the main example of lyotropic LCPs is the commercial aramid known as Kevlar. Chemical structure of this aramid consists of linearly substituted aromatic rings linked by amide groups. In a similar way, several series of thermotropic LCPs have been commercially produced by several companies (e.g., Vectra / Celanese). A high number of LCPs, produced in the 1980s, displayed order in the melt phase analogous to that exhibited by nonpolymeric liquid crystal

is a 1988 Japanese anime OVA release directed by Yuji Moriyama. It is the third installment of the Project A-ko series. Plot Project A-ko 3: Cinderella Rhapsody opens with a fluidly-animated dream sequence of A-ko, B-ko, and C-ko engaged in a game of pool. However, this has nothing to do with the rest of the storyline. It's Spring Break for the students of Graviton High. While B-ko plots to whisk C-ko away to some secluded location, C-ko dreams only of spending time with A-ko, having fun as usual. A-ko, however, has other plans. She decides that it's time to "stop hanging around" with C-ko and find a boyfriend. Unsatisfied with her wardrobe, she gets a job at a local fast food restaurant to earn money to buy new clothes. This leaves C-Ko feeling quite lonely, so she spends most of her days waiting for A-ko to get off of work. One day, A-ko (literally) runs into Kei Yuki, a handsome biker. To her great delight, Kei returns to the restaurant where she works and seems to hang about. B-ko also notices Kei and decides to "steal" him from A-ko. Later, C-ko sees A-ko and Kei arriving on Kei's motorcycle. She runs up to A-ko and snarls and hisses at Kei like a feral cat, angry that he is robbing her of A-ko's affections. A-ko and B-ko's battle for the habitually silent Kei culminates in a disastrous "date" at the Alpha Cygnans' Space Hotel. During the posh event, A-ko realizes that she removed her magic armbands which keep her powers under control. Without them, her strength is
https://en.wikipedia.org/wiki/First-order%20partial%20differential%20equation
In mathematics, a first-order partial differential equation is a partial differential equation that involves only first derivatives of the unknown function of n variables. The equation takes the form Such equations arise in the construction of characteristic surfaces for hyperbolic partial differential equations, in the calculus of variations, in some geometrical problems, and in simple models for gas dynamics whose solution involves the method of characteristics. If a family of solutions of a single first-order partial differential equation can be found, then additional solutions may be obtained by forming envelopes of solutions in that family. In a related procedure, general solutions may be obtained by integrating families of ordinary differential equations. General solution and complete integral The general solution to the first order partial differential equation is a solution which contains an arbitrary function. But, the solution to the first order partial differential equations with as many arbitrary constants as the number of independent variables is called the complete integral. The following n-parameter family of solutions is a complete integral if . The below discussions on the type of integrals are based on the textbook A Treatise on Differential Equations (Chaper IX, 6th edition, 1928) by Andrew Forsyth. Complete integral The solutions are described in relatively simple manner in two or three dimensions with which the key concepts are trivially extended to
https://en.wikipedia.org/wiki/GTP%20cyclohydrolase%20I
GTP cyclohydrolase I (GTPCH) () is a member of the GTP cyclohydrolase family of enzymes. GTPCH is part of the folate and biopterin biosynthesis pathways. It is responsible for the hydrolysis of guanosine triphosphate (GTP) to form 7,8-dihydroneopterin triphosphate (7,8-DHNP-3'-TP, 7,8-NH2-3'-TP). Gene GTPCH is encoded by the gene GCH1. Several alternatively spliced transcript variants encoding different isoforms have been described; however, not all of the variants give rise to a functional enzyme. Clinical significance At least 94 disease-causing mutations in this gene have been discovered. Mutations in this gene are associated with two disorders: autosomal recessive GTP cyclohydrolase I deficiency and autosomal dominant GTP cyclohydrolase I deficiency. These may present with malignant phenylketonuria (PKU) and hyperphenylalaninemia (HPA) and lead to a lack of certain neurotransmitters (dopamine, norepinephrine, epinephrine and serotonin). The dominant form, with mutation in only one of the two alleles for GTP cyclohydrolase I, causes dopamine-responsive dystonia, characterized by childhood-onset dystonia. Patients with the recessive form have mutations in both alleles for GTP cyclohydrolase I. Patients present with developmental delays and neurological dysfunction with trunk hypotonia, hypertonia of the extremities, abnormal movements, tremors, convulsions, and sometimes autonomic dysfunction. Response to treatment is variable and the long-term and functional outcome
https://en.wikipedia.org/wiki/GTP%20cyclohydrolase
GTP cyclohydrolases are enzymes that catalyze imidazole ring opening of guanosine triphosphate (GTP). This reaction is the committed step in the biosynthesis of multiple coenzymes (such as riboflavin and folate), tRNA bases, and the phytotoxin toxoflavin. Several GTP cyclohydrolases exist, which sometimes synthesize different products for different pruposes: GTP cyclohydrolase I, part of the tetrahydrobiopterin, tetrahydrofolate, queuosine and other biosynthetic pathways GTP cyclohydrolase Ia, GTP cyclohydrolase Ib, part of the tetrahydrobiopterin, tetrahydrofolate, queueosine and other biosynthetic pathways GTP cyclohydrolase II, part of the riboflavin and toxoflavin biosynthetic pathways GTP cyclohydrolase IIa (or GTP cyclohydrolase III), part of the riboflavin and deazaflavin cofactor biosynthetic pathways GTP cyclohydrolase IV GTP cyclohydrolase MptA, GTP cyclohydrolase Ib paralog These enzymes require divalent cations for catalysis.

https://en.wikipedia.org/wiki/Wavelet%20modulation
Wavelet modulation, also known as fractal modulation, is a modulation technique that makes use of wavelet transformations to represent the data being transmitted. One of the objectives of this type of modulation is to send data at multiple rates over a channel that is unknown. If the channel is not clear for one specific bit rate, meaning that the signal will not be received, the signal can be sent at a different bit rate where the signal-to-noise ratio is higher.

https://en.wikipedia.org/wiki/Enumerated%20type
In computer programming, an enumerated type (also called enumeration, enum, or factor in the R programming language, and a categorical variable in statistics) is a data type consisting of a set of named values called elements, members, enumeral, or enumerators of the type. The enumerator names are usually identifiers that behave as constants in the language. An enumerated type can be seen as a degenerate tagged union of unit type. A variable that has been declared as having an enumerated type can be assigned any of the enumerators as a value. In other words, an enumerated type has values that are different from each other, and that can be compared and assigned, but are not specified by the programmer as having any particular concrete representation in the computer's memory; compilers and interpreters can represent them arbitrarily. For example, the four suits in a deck of playing cards may be four enumerators named Club, Diamond, Heart, and Spade, belonging to an enumerated type named suit. If a variable V is declared having suit as its data type, one can assign any of those four values to it. Although the enumerators are usually distinct, some languages may allow the same enumerator to be listed twice in the type's declaration. The names of enumerators need not be semantically complete or compatible in any sense. For example, an enumerated type called color may be defined to consist of the enumerators Red, Green, Zebra, Missing, and Bacon. In some languages, the declarat
https://en.wikipedia.org/wiki/Eukaryotic%20chromosome%20fine%20structure
Eukaryotic chromosome fine structure refers to the structure of sequences for eukaryotic chromosomes. Some fine sequences are included in more than one class, so the classification listed is not intended to be completely separate. Chromosomal characteristics Some sequences are required for a properly functioning chromosome: Centromere: Used during cell division as the attachment point for the spindle fibers. Telomere: Used to maintain chromosomal integrity by capping off the ends of the linear chromosomes. This region is a microsatellite, but its function is more specific than a simple tandem repeat. Throughout the eukaryotic kingdom, the overall structure of chromosome ends is conserved and is characterized by the telomeric tract - a series of short G-rich repeats. This is succeeded by an extensive subtelomeric region consisting of various types and lengths of repeats - the telomere associated sequences (TAS). These regions are generally low in gene density, low in transcription, low in recombination, late replicating, are involved in protecting the end from degradation and end-to-end fusions and in completing replication. The subtelomeric repeats can rescue chromosome ends when telomerase fails, buffer subtelomerically located genes against transcriptional silencing and protect the genome from deleterious rearrangements due to ectopic recombination. They may also be involved in fillers for increasing chromosome size to some minimum threshold level necessary for chromo
https://en.wikipedia.org/wiki/Firefly%20luciferase
Firefly luciferase is the light-emitting enzyme responsible for the bioluminescence of fireflies and click beetles. The enzyme catalyses the oxidation of firefly luciferin, requiring oxygen and ATP. Because of the requirement of ATP, firefly luciferases have been used extensively in biotechnology. Mechanism of reaction The chemical reaction catalyzed by firefly luciferase takes place in two steps: luciferin + ATP → luciferyl adenylate + PPi luciferyl adenylate + O2 → oxyluciferin + AMP + light Light is produced because the reaction forms oxyluciferin in an electronically excited state. The reaction releases a photon of light as oxyluciferin goes back to the ground state. Luciferyl adenylate can additionally participate in a side reaction with O2 to form hydrogen peroxide and dehydroluciferyl-AMP. About 20% of the luciferyl adenylate intermediate is oxidized in this pathway. Firefly luciferase generates light from luciferin in a multistep process. First, D-luciferin is adenylated by MgATP to form luciferyl adenylate and pyrophosphate. After activation by ATP, luciferyl adenylate is oxidized by molecular oxygen to form a dioxetanone ring. A decarboxylation reaction forms an excited state of oxyluciferin, which tautomerizes between the keto-enol form. The reaction finally emits light as oxyluciferin returns to the ground state. Bifunctionality Luciferase can function in two different pathways: a bioluminescence pathway and a CoA-ligase pathway. In both pathways, luc

https://en.wikipedia.org/wiki/Neglect%20of%20probability
The neglect of probability, a type of cognitive bias, is the tendency to disregard probability when making a decision under uncertainty and is one simple way in which people regularly violate the normative rules for decision making. Small risks are typically either neglected entirely or hugely overrated. The continuum between the extremes is ignored. The term probability neglect was coined by Cass Sunstein. There are many related ways in which people violate the normative rules of decision making with regard to probability including the hindsight bias, the neglect of prior base rates effect, and the gambler's fallacy. However, this bias is different, in that, rather than incorrectly using probability, the actor disregards it. "We have no intuitive grasp of risk and thus distinguish poorly among different threats," Dobelli has written. "The more serious the threat and the more emotional the topic (such as radioactivity), the less reassuring a reduction in risk seems to us." Studies Adults In a 1972 experiment, participants were divided into two groups, with the former being told they would receive a mild electric shock and the latter told that there was a 50 percent chance they would receive such a shock. When the subjects' physical anxiety was measured, there was no difference between the two groups. This lack of difference remained even when the second group's chance of being shocked was lowered to 20 percent, then ten, then five. The conclusion: "we respond to the expec

The Serra do Mar coastal forests is an ecoregion of the tropical moist forests biome. It is part of the Atlantic Forest of eastern South America. This ecoregion has an outstanding biodiversity consisting of flora, mammals, birds, and herpetofauna. Geography The Serra do Mar mountain range defines this ecoregion. The Serra do Mar coastal forests extend from the Atlantic coast up the seaward-facing slopes of the Serra do Mar, along the southern coast of Brazil for about . The ecoregion lies within the states of São Paulo, Rio de Janeiro, Paraná, Minas Gerais, Espírito Santo, Santa Catarina, and Rio Grande do Sul. Climate The climate is subtropical with high levels of annual rainfall. Annual rainfall ranges from 1,400 to 4,000 millimeters without a dry season. Flora The plant communities in the ecoregion include coastal scrub, lowland rain forests, and montane rain forests. The lowland rain forests are composed of four strata, including a dense canopy layer and emergent trees which grow up to 30 meters high. Common canopy and emergent trees include species from the plant families Leguminosae (Copaifera trapezifolia), Sapotaceae (species of Pouteria and Chrysophyllum), and Lauraceae. Tropical montane cloud forests occur from 1,200 to 1,500 meters elevation in the northern portion of the ecoregion, and 700 to 1100 meters in the south. They are found on seaward-facing mountain slopes with high rainfall and frequent year-round cloud cover. Tropical montane cloud forests ar

Clock were an English band primarily led by Stu Allan and Pete Pritchard and fronted by rapper Marcus Thomas (using the name ODC MC) and vocalist Lorna Saunders (using the name Tinka), though the single "Keep the Fires Burning" was sung by Georgia Lewis. They resembled many Eurodance acts of the time with a female singer and male rapper. Their earlier work was harder, similar to Cappella, but once they started releasing covers, their sound became more dance/pop oriented. Thomas left in 1998 to join the band Tzant, to be replaced by Ché-gun Peters. They had a string of top 40 hits with nine covers during the 1990s on the UK Singles Chart. They also released hardcore versions of their hits under the name Visa. Clock broke up in 1999 due to a number of personal reasons; they were not able to continue at the same pace as they had before. In 2004, Saunders appeared on BBC Television's Never Mind the Buzzcocks in the celebrity line-up. It was announced that she was now working as a legal secretary.

https://en.wikipedia.org/wiki/Frege%27s%20theorem
In metalogic and metamathematics, Frege's theorem is a metatheorem that states that the Peano axioms of arithmetic can be derived in second-order logic from Hume's principle. It was first proven, informally, by Gottlob Frege in his 1884 Die Grundlagen der Arithmetik (The Foundations of Arithmetic) and proven more formally in his 1893 Grundgesetze der Arithmetik I (Basic Laws of Arithmetic I). The theorem was re-discovered by Crispin Wright in the early 1980s and has since been the focus of significant work. It is at the core of the philosophy of mathematics known as neo-logicism (at least of the Scottish School variety). Overview In The Foundations of Arithmetic (1884), and later, in Basic Laws of Arithmetic (vol. 1, 1893; vol. 2, 1903), Frege attempted to derive all of the laws of arithmetic from axioms he asserted as logical (see logicism). Most of these axioms were carried over from his Begriffsschrift; the one truly new principle was one he called the Basic Law V (now known as the axiom schema of unrestricted comprehension): the "value-range" of the function f(x) is the same as the "value-range" of the function g(x) if and only if ∀x[f(x) = g(x)]. However, not only did Basic Law V fail to be a logical proposition, but the resulting system proved to be inconsistent, because it was subject to Russell's paradox. The inconsistency in Frege's Grundgesetze overshadowed Frege's achievement: according to Edward Zalta, the Grundgesetze "contains all the essential steps of a val

It is surrounded on three sides by the Canada–United States border. To the north is Point Roberts, Washington, and to the east and south are the San Juan Islands. There is a First Nations reserve on the island for the Tsayout and Tseycum Nations. The island has a permanent population of around 350, however, this number increases during the summer season. Approximately half of the island is in the Gulf Islands National Park Reserve (GINPR) that was formed in 2003 from a gift of ecologically sensitive land by Ulla Ressner and John Fry, existing provincial parks, an Ecological Reserve, and other Crown land. History The island was first used by indigenous people who called the island "Long Nose," due to the island's long north-eastern tapering shoreline that ends at East Point. The name Saturna comes from the Spanish naval schooner Santa Saturnina ("St. Saturnina") captained by pilot (piloto) José María Narváez, which along with a longboat of the Spanish naval packet ship San Carlos, explored the island's coast in an excursion under the overall command of Pilot Juan Pantoja y Arriaga in 1791. The name was initially applied only to East Point. The contraction to "Saturna" applied to the whole island was first made by Dionisi
https://en.wikipedia.org/wiki/Australian%20Bureau%20of%20Statistics
The Australian Bureau of Statistics (ABS) is a government agency that collects and analyzes statistics on economic, population, environmental, and social issues. It provides evidence-based advice to federal, state, and territory governments. The ABS conducts the national Census of Population and Housing every five years and publishes many of its findings on the agency's website. History In early 1901, statistics were collected by each state and territory of Australia for their own separate use. Although attempts were made to coordinate collections through an annual Conference of Statisticians, it was decided that a national statistical office would be required to develop nationally comparable statistics. The Commonwealth Bureau of Census and Statistics (CBCS) was established under the Census and Statistics Act in 1905. Sir George Knibbs was appointed as the first Commonwealth Statistician. Initially, the bureau was located in Melbourne and was attached to the Department of Home Affairs. In 1928, the bureau relocated to Canberra, and in 1932 moved to the Treasury portfolio. Initially, the states maintained their own statistical offices and worked together with the CBCS to produce national data. However, some states found it difficult to resource a state statistical office to the level required for an adequate statistical service. In 1924, the Tasmanian Statistical Office transferred to the Commonwealth. On 20 August 1957, the New South Wales (NSW) Bureau of Statistics was m

https://en.wikipedia.org/wiki/Claudin
Claudins are a family of proteins which, along with occludin, are the most important components of the tight junctions (zonulae occludentes). Tight junctions establish the paracellular barrier that controls the flow of molecules in the intercellular space between the cells of an epithelium. They have four transmembrane domains, with the N-terminus and the C-terminus in the cytoplasm. Structure Claudins are small (20–24/27 kilodalton (kDa)) transmembrane proteins which are found in many organisms, ranging from nematodes to human beings. They all have a very similar structure. Claudins span the cellular membrane 4 times, with the N-terminal end and the C-terminal end both located in the cytoplasm, and two extracellular loops which show the highest degree of conservation. Claudins have both cis and trans interactions between cell membranes. Cis-interactions is when claudins on the same membrane interact, one way they interact is by transmembrane domain having molecular interactions. Trans-interaction is when claudins of neighboring cells interact through their extracellular loops. Cis-interactions is also known as side-to-side interactions and trans-interactions is also known as head-to-head interactions. Generally the tight junction is known for its impermeability. However, depending on the type of claudin and their interactions there is selective permeability. This includes charge selectivity and size selectivity. N-terminal The N-terminal end is usually very short (1–10

https://en.wikipedia.org/wiki/Hyperplane%20separation%20theorem
In geometry, the hyperplane separation theorem is a theorem about disjoint convex sets in n-dimensional Euclidean space. There are several rather similar versions. In one version of the theorem, if both these sets are closed and at least one of them is compact, then there is a hyperplane in between them and even two parallel hyperplanes in between them separated by a gap. In another version, if both disjoint convex sets are open, then there is a hyperplane in between them, but not necessarily any gap. An axis which is orthogonal to a separating hyperplane is a separating axis, because the orthogonal projections of the convex bodies onto the axis are disjoint. The hyperplane separation theorem is due to Hermann Minkowski. The Hahn–Banach separation theorem generalizes the result to topological vector spaces. A related result is the supporting hyperplane theorem. In the context of support-vector machines, the optimally separating hyperplane or maximum-margin hyperplane is a hyperplane which separates two convex hulls of points and is equidistant from the two. Statements and proof In all cases, assume to be disjoint, nonempty, and convex subsets of . The summary of the results are as follows: The number of dimensions must be finite. In infinite-dimensional spaces there are examples of two closed, convex, disjoint sets which cannot be separated by a closed hyperplane (a hyperplane where a continuous linear functional equals some constant) even in the weak sense where the

https://en.wikipedia.org/wiki/Ambiguity%20effect
The ambiguity effect is a cognitive bias where decision making is affected by a lack of information, or "ambiguity". The effect implies that people tend to select options for which the probability of a favorable outcome is known, over an option for which the probability of a favorable outcome is unknown. The effect was first described by Daniel Ellsberg in 1961. Example As an example, consider a bucket containing 30 balls. The balls are either red, black or white. Ten of the balls are red, and the remaining 20 are either black or white, with all combinations of black and white being equally likely. In option X, drawing a red ball wins a person $100, and in option Y, drawing a black ball wins them $100. The probability of picking a winning ball is the same for both options X and Y. In option X, the probability of selecting a winning ball is 1 in 3 (10 red balls out of 30 total balls). In option Y, despite the fact that the number of black balls is uncertain, the probability of selecting a winning ball is also 1 in 3. This is because the number of black balls is equally distributed among all possibilities between 0 and 20. The difference between the two options is that in option X, the probability of a favorable outcome is known, but in option Y, the probability of a favorable outcome is unknown ("ambiguous"). In spite of the equal probability of a favorable outcome, people have a greater tendency to select a ball under option X, where the probability of selecting a winning

In complex analysis, Jordan's lemma is a result frequently used in conjunction with the residue theorem to evaluate contour integrals and improper integrals. The lemma is named after the French mathematician Camille Jordan. Statement Consider a complex-valued, continuous function , defined on a semicircular contour of positive radius lying in the upper half-plane, centered at the origin. If the function is of the form with a positive parameter , then Jordan's lemma states the following upper bound for the contour integral: with equality when vanishes everywhere, in which case both sides are identically zero. An analogous statement for a semicircular contour in the lower half-plane holds when . Remarks If is continuous on the semicircular contour for all large and then by Jordan's lemma For the case , see the estimation lemma. Compared to the estimation lemma, the upper bound in Jordan's lemma does not explicitly depend on the length of the contour . Application of Jordan's lemma Jordan's lemma yields a simple way to calculate the integral along the real axis of functions holomorphic on the upper half-plane and continuous on the closed upper half-plane, except possibly at a finite number of non-real points , , …, . Consider the closed contour , which is the concatenation of the paths and shown in the picture.

https://en.wikipedia.org/wiki/Kerley%20lines
Kerley lines are a sign seen on chest radiographs with interstitial pulmonary edema. They are thin linear pulmonary opacities caused by fluid or cellular infiltration into the interstitium of the lungs. They are named after Irish neurologist and radiologist Peter Kerley. Associated conditions They are suggestive for the diagnosis of congestive heart failure, but are also seen in various non-cardiac conditions such as pulmonary fibrosis, interstitial deposition of heavy metal particles or carcinomatosis of the lung. Chronic Kerley B lines may be caused by fibrosis or hemosiderin deposition caused by recurrent pulmonary edema. Types Kerley A lines These are longer (at least 2cm and up to 6cm) unbranching lines coursing diagonally from the hila out to the periphery of the lungs. They are caused by distension of anastomotic channels between peripheral and central lymphatics of the lungs. Kerley A lines are less commonly seen than Kerley B lines. Kerley A lines are never seen without Kerley B or C lines. Kerley B lines These are short parallel lines at the lung periphery. These lines represent interlobular septa, which are usually less than 1 cm in length and parallel to one another at right angles to the pleura. They are located peripherally in contact with the pleura, but are generally absent along fissural surfaces. They may be seen in any zone but are most frequently observed at the lung bases at the costophrenic angles on the PA radiograph, and in the substernal region

All the Time in the World is the second studio album by the band Lazlo Bane. It was self-released by the band more than five years after their debut album, 11 Transistor. Background and release The work on the album started in late 90's when the band was still signed to Almo Sounds label. According to Chad Fischer the release of the album was shelved around 2000 as the label was sold to Universal Music Group. Lazlo Bane managed to acquire the album from Almo Sounds but struggled to release it by themselves. Early self released promo copies of the album was distributed in 2000, while the first commercially released track was "Superman" as it appeared on the soundtrack for the film The Tao of Steve. During that period "Superman" got noticed by Zach Braff and later became the theme song for the television series Scrubs. All the Time in the World finally received an official release on CD and as a digital download through CD Baby in September 2002. Unlike the band's debut 11 Transistor with its guitar-heavy stylings, the songs on All the Time in the World expand the variety of instruments and feature banjo, piano, saxophone and strings. While working on the album the band wrote a large number of new songs, much more than were released. Some of them were included on the band's next release, Back Sides. Versions and differences There are several differences between the early 2000 promo and the official 2002 releases. The CD promo edition featured the song "I'll Be Happy" as
https://en.wikipedia.org/wiki/Hydrosalpinx
A hydrosalpinx is a condition that occurs when a fallopian tube is blocked and fills with serous or clear fluid near the ovary (distal to the uterus). The blocked tube may become substantially distended giving the tube a characteristic sausage-like or retort-like shape. The condition is often bilateral and the affected tubes may reach several centimeters in diameter. The blocked tubes cause infertility. A fallopian tube filled with blood is a hematosalpinx, and with pus a pyosalpinx. Hydrosalpinx is a composite of the Greek words ὕδωρ (hydōr – "water") and σάλπιγξ (sálpinx – "trumpet"); its plural is hydrosalpinges. Signs and symptoms Symptoms can vary. Some patients have lower often recurring abdominal pain or pelvic pain, while others may be asymptomatic. As tubal function is impeded, infertility is a common symptom. Patients who are not trying to get pregnant and have no pain, may go undetected. Endometriosis, ruptured appendicitis, and abdominal surgery sometimes are associated with the problem. As a reaction to injury, the body rushes inflammatory cells into the area, and inflammation and later healing result in loss of the fimbria and closure of the tube. These infections usually affect both fallopian tubes, and although a hydrosalpinx can be one-sided, the other tube on the opposite side is often abnormal. By the time it is detected, the tubal fluid usually is sterile, and does not contain an active infection. (Not symptoms) Cause The major cause for distal tubal

https://en.wikipedia.org/wiki/Diairesis
Diairesis (, "division") is a form of classification used in ancient (especially Platonic) logic that serves to systematize concepts and come to definitions. When defining a concept using diairesis, one starts with a broad concept, then divides this into two or more specific sub-concepts, and this procedure is repeated until a definition of the desired concept is reached. Aristotle makes extensive use of diaresis in categorization as basis for syllogizing. He makes clear, however, that definition by diaresis does not in itself prove anything. Apart from this definition, the procedure also results in a taxonomy of other concepts, ordered according to a general–specific relation. The founder of diairesis as a method was Plato. Later ancient logicians (including Aristotle) and practitioners of other ancient sciences have employed diairetic modes of classification, e.g., to classify plants in ancient biology. Plato's method of definition Diairesis is Plato's later method of definition based on division, developed in the Platonic dialogues Phaedrus, Sophist, Statesman, and Philebus. Further applications are found in the Laws and Timaeus. It is a means of attempting to reach a definition by which a collection of candidates is repeatedly divided into two parts with one part eliminated until a suitable definition is discovered. A complementary term is merismos (cf. English merism: parsing or the distinguishing of parts, as opposed to diairesis, which is the division of a genu

https://en.wikipedia.org/wiki/Wavelength%20shifter
A wavelength shifter is a photofluorescent material that absorbs higher frequency photons and emits lower frequency photons. The material absorbs one photon, and emits one or multiple lower-energy photons. The relaxation time of the excited molecule is usually in the order of nanoseconds. Applications Wavelength shifters are often used in particle physics to collect scintillation or Cherenkov light in particle detectors. Materials, such as acrylic slaps or optical fibers, are typically either doped with wavelength-shifting molecules or coated with wavelength-shifting paint. Wavelength-shifting technology is of particular interest for low-background supernova neutrino detectors such as IceCube, Super-Kamiokande or its successor Hyper-Kamiokande. Here, wavelength shifters offer two advantages: As these types of detectors are based on the emission of Cherenkov photons of superluminous secondary particles from the neutrino interaction, absorbing more photons in the UV range and shifting them to the visible range detectable by conventional PMTs is beneficial. In addition, with wavelength shifters larger collection areas can be covered price-efficiently as compared to standard PMT-based sensors. An example of a sensor making use of wavelength-shifting technology is the Wavelength-shifting Optical Module (WOM) envisaged for an extension of the IceCube detector. Furthermore, wavelength shifting materials can be used to increase the efficiency of a photovoltaic cell (solar cell) b

Tungsten hexachloride is an inorganic chemical compound of tungsten and chlorine with the chemical formula . This dark violet blue compound exists as volatile crystals under standard conditions. It is an important starting reagent in the preparation of tungsten compounds. Other examples of charge-neutral hexachlorides are rhenium(VI) chloride and molybdenum(VI) chloride. The highly volatile tungsten hexafluoride is also known. As a d0 atom, tungsten hexachloride is diamagnetic. Preparation and structure Tungsten hexachloride can be prepared by chlorinating tungsten metal in a sealed tube at 600 °C: Tungsten hexachloride exists in both blue and red polymorphs, referred to respectively as α and β. The wine-red β can be obtained by rapid cooling whereas the blue α form is more stable at room temperature. Although these polymorphs are distinctly colored, their molecular structures are very similar. Both polymorphs feature molecules that have octahedral, in which all six W–Cl bonds are equivalent, and their length is equal to 224–226 pm. The densities are very similar: 3.68 g/cm3 for α and 3.62 g/cm3 for β. The low temperature form is slightly more dense, as expected. Reactions Tungsten hexachloride is readily hydrolyzed, even by moist air, giving the orange oxychlorides and , and subsequently, tungsten trioxide. is soluble in carbon disulfide, carbon tetrachloride, and phosphorus oxychloride.

https://en.wikipedia.org/wiki/Sympathetic%20ganglia
The sympathetic ganglia, or paravertebral ganglia, are autonomic ganglia of the sympathetic nervous system. Ganglia are 20,000 to 30,000 afferent and efferent nerve cell bodies that run along on either side of the spinal cord. Afferent nerve cell bodies bring information from the body to the brain and spinal cord, while efferent nerve cell bodies bring information from the brain and spinal cord to the rest of the body. The cell bodies create long sympathetic chains that are on either side of the spinal cord. They also form para- or pre-vertebral ganglia of gross anatomy. The efferent nerve cell bodies bring information from the brain to the body regarding perceptions of danger. This perception of danger can instigate the fight-or-flight response associated with the sympathetic nervous system. The fight-or-flight response is adaptive when there is a real and present danger which can be avoided or diminished through increased sympathetic activity. Sympathetic activity could be increased heart rate, dilated pupils, or sweaty palms, for example. The fight-or-flight response is maladaptive when the danger is imagined, prolonged, or when it lasts after the threat is over. When the intensity or duration of the response is excessive, the individual may meet criteria for a variety of psychological disorders. Neuroblastoma tumors can arise from the sympathetic ganglia tissue. Structure Sympathetic chain ganglia The bilaterally symmetric sympathetic chain ganglia, also called the par

https://en.wikipedia.org/wiki/Photochromic%20lens
A photochromic lens is an optical lens that darkens on exposure to light of sufficiently high frequency, most commonly ultraviolet (UV) radiation. In the absence of activating light, the lenses return to their clear state. Photochromic lenses may be made of polycarbonate, or another plastic. Glass lenses use visible light to darken. They are principally used in glasses that are dark in bright sunlight, but clear, or more rarely, lightly tinted in low ambient light conditions. They darken significantly within about a minute of exposure to bright light and take somewhat longer to clear. A range of clear and dark transmittances is available. In one sort of technology, molecules of silver chloride or another silver halide are embedded in photochromic lenses. They are transparent to visible light without significant ultraviolet component, which is normal for artificial lighting. In another sort of technology, organic photochromic molecules, when exposed to ultraviolet (UV) rays as in direct sunlight, undergo a chemical process that causes them to change shape and absorb a significant percentage of the visible light, i.e., they darken. These processes are reversible; once the lens is removed from strong sources of UV rays the photochromic compounds return to their transparent state. Invention Photochromic lenses were developed by William H. Armistead and Stanley Donald Stookey at the Corning Glass Works Inc. in the 1960s. Technical details Mechanism The glass version of these

https://en.wikipedia.org/wiki/Guide%20RNA
A guide RNA (gRNA) is a piece of RNA that functions as a guide for RNA- or DNA-targeting enzymes, with which it forms complexes. Very often these enzymes will delete, insert or otherwise alter the targeted RNA or DNA. They occur naturally, serving important functions, but can also be designed to be used for targeted editing, such as with CRISPR-Cas9 and CRISPR-Cas12. History RNA-editing Guide RNA was discovered in 1990 by B. Blum, N. Bakalara, and L. Simpson in maxicircle DNA and contains sequences matching those within the edited regions of the mRNA. They enable the cleavage, insertion, and deletion of bases. Guide RNA in Protists Trypanosomatid protists and other kinetoplastids have a novel post-transcriptional mitochondrial RNA modification process known as "RNA editing". They have a large segment of highly organized DNA segments in their mitochondria. This mitochondrial DNA is circular and is divided into maxicircles and minicircles. A cell contains about 20-50 maxicircles which have both coding and non coding regions. The coding region is highly conserved (16-17kb) and the non-coding region varies depending on the species. Minicircles are small but more numerous than maxicircles. Minicircles constitute 95% of the mass of kinetoplastid DNA. Maxicircles can encode "cryptogenes" and some gRNAs; minicircles can encode the majority of gRNAs. As many as 1000 gRNAs can be encoded by 250 or more minicircles. Some gRNA genes show identical insertion and deletion sites even if t

https://en.wikipedia.org/wiki/Tunica%20vaginalis
The tunica vaginalis is a pouch of serous membrane within the scrotum that lines the testis and epididymis (visceral layer of tunica vaginalis), and the inner surface of the scrotum (parietal layer of tunica vaginalis). It is the outermost of the three layers that constitute the capsule of the testis, with the tunica albuginea of penis situated beneath it. It is the remnant of a pouch of peritoneum which is pulled into the scrotum by the testis as it descends out of the abdominal cavity during foetal development. Anatomy Visceral layer The visceral layer of tunica vaginalis of testis (lamina visceralis tunicae vaginalis testis) is the portion of the tunica vaginalis that covers the testis and epididymis. It is the superficial-most of the three layers that constitute the capsule of the testis, with the tunica albuginea of testis situated deep to it. Posteriorly, the visceral layer does not line the surface of the testis - instead, it passes onto the epididymis where the latter attaches to the testis before continuing onto the inner surface of the scrotum as the parietal layer. Parietal layer The parietal layer of tunica vaginalis of testis (lamina parietalis tunicae vaginalis testis) is the portion of the tunica vaginalis that lines the inner surface of the scrotum. It is supported by the internal spermatic fascia. Cavity of the tunica vaginalis The cavity of the tunica vaginalis (also: cavum of the tunica vaginalis, or cavum vaginale) is the cavity between the viscer
https://en.wikipedia.org/wiki/Small%20nucleolar%20RNA
In molecular biology, small nucleolar RNAs (snoRNAs) are a class of small RNA molecules that primarily guide chemical modifications of other RNAs, mainly ribosomal RNAs, transfer RNAs and small nuclear RNAs. There are two main classes of snoRNA, the C/D box snoRNAs, which are associated with methylation, and the H/ACA box snoRNAs, which are associated with pseudouridylation. SnoRNAs are commonly referred to as guide RNAs but should not be confused with the guide RNAs that direct RNA editing in trypanosomes or the guide RNAs (gRNAs) used by Cas9 for CRISPR gene editing. snoRNA guided modifications After transcription, nascent rRNA molecules (termed pre-rRNA) undergo a series of processing steps to generate the mature rRNA molecule. Prior to cleavage by exo- and endonucleases, the pre-rRNA undergoes a complex pattern of nucleoside modifications. These include methylations and pseudouridylations, guided by snoRNAs. Methylation is the attachment or substitution of a methyl group onto various substrates. The rRNA of humans contain approximately 115 methyl group modifications. The majority of these are 2′O-ribose-methylations (where the methyl group is attached to the ribose group). Pseudouridylation is the conversion (isomerisation) of the nucleoside uridine to a different isomeric form pseudouridine (Ψ). This modification consists of a 180º rotation of the uridine base around its glycosyl bond to the ribose of the RNA backbone. After this rotation, the nitrogenous base contrib

https://en.wikipedia.org/wiki/Verhoeff%20algorithm
The Verhoeff algorithm is a checksum for error detection first published by Dutch mathematician Jacobus Verhoeff in 1969. It was the first decimal check digit algorithm which detects all single-digit errors, and all transposition errors involving two adjacent digits, which was at the time thought impossible with such a code. The method was independently discovered by H. Peter Gumm in 1985, this time including a formal proof and an extension to any base. Goals Verhoeff had the goal of finding a decimal code—one where the check digit is a single decimal digit—which detected all single-digit errors and all transpositions of adjacent digits. At the time, supposed proofs of the nonexistence of these codes made base-11 codes popular, for example in the ISBN check digit. His goals were also practical, and he based the evaluation of different codes on live data from the Dutch postal system, using a weighted points system for different kinds of error. The analysis broke the errors down into a number of categories: first, by how many digits are in error; for those with two digits in error, there are transpositions (ab → ba), twins (aa → 'bb'), jump transpositions (abc → cba), phonetic (1a → a0), and jump twins (aba → cbc). Additionally there are omitted and added digits. Although the frequencies of some of these kinds of errors might be small, some codes might be immune to them in addition to the primary goals of detecting all singles and transpositions. The phonetic errors in

Freivalds' algorithm (named after Rūsiņš Mārtiņš Freivalds) is a probabilistic randomized algorithm used to verify matrix multiplication. Given three n × n matrices , , and , a general problem is to verify whether . A naïve algorithm would compute the product explicitly and compare term by term whether this product equals . However, the best known matrix multiplication algorithm runs in time. Freivalds' algorithm utilizes randomization in order to reduce this time bound to with high probability. In time the algorithm can verify a matrix product with probability of failure less than . The algorithm Input Three n × n matrices , , and . Output Yes, if ; No, otherwise. Procedure Generate an n × 1 random 0/1 vector . Compute . Output "Yes" if ; "No," otherwise. Error If , then the algorithm always returns "Yes". If , then the probability that the algorithm returns "Yes" is less than or equal to one half. This is called one-sided error. By iterating the algorithm k times and returning "Yes" only if all iterations yield "Yes", a runtime of and error probability of is achieved. Example Suppose one wished to determine whether: A random two-element vector with entries equal to 0 or 1 is selected say and used to compute: This yields the zero vector, suggesting the possibility that AB = C. However, if in a second trial the vector is selected, the result becomes: The result is nonzero, proving that in fact AB ≠ C. There are four two-element 0/1 vectors, and half of t

Alexander Harkavy (, , Aleksandr Garkavi; May 5, 1863 at Nowogrudok (), Minsk guberniya (governorate), Russian Empire (now Navahrudak, Hrodna Voblast, Belarus) - 1939 in New York City) was a Russian-born American writer, lexicographer and linguist. Biography Alexander Harkavy was educated privately, and at an early age evinced a predilection for philology. In 1879 he went to Vilna, where he worked in the printing-office of the Romm Brothers. After the antisemitic pogroms of 1880 in Russia, Harkavy joined the Jewish Am Olam (Eternal People) back-to-the-land movement. Unlike Bilu, which directed its activities towards Palestine, Am Olam saw a Jewish future in the United States. In 1882 Harkavy emigrated to the United States. He however did not succeed in joining or establishing an agricultural Am Olam entity, finding himself in search of a living. He was in Paris in 1885, New York in 1886, Montreal in 1887, Baltimore in 1889 and back in New York in 1890. During these years of wandering Harkavy studied, taught, and published his first journalistic and scholarly compositions. In Montreal he achieved some acclaim among local Hebraists, and founded a branch of Chovevei Zion, of which he served as president. Harkavy published in lithograph form one issue of a Yiddish newspaper, Die Tzeit (The Time), the first Jewish newspaper in Canada. He also wrote the first history of the Jews in Canada. Back in the United States he participated in the activities of the anarchist group Pio
https://en.wikipedia.org/wiki/Rocky%20Mountain%20Front
The Rocky Mountain Front is a somewhat unified geologic and ecosystem area in North America where the eastern slopes of the Rocky Mountains meet the plains. In 1983, the Bureau of Land Management called the Rocky Mountain Front "a nationally significant area because of its high wildlife, recreation, and scenic values". Conservationists Gregory Neudecker, Alison Duvall, and James Stutzman have described the Rocky Mountain Front as an area that warrants "the highest of conservation priorities" because it is largely unaltered by development and contains "unparalleled" numbers of wildlife. Defining the Rocky Mountain Front Although the Rocky Mountain Front is clearly distinct from both plains and mountains, in places like the Wyoming Basin, Montana, and New Mexico it is more ambiguous. One definition of the front is that it is a "transition zone between the Rocky Mountains and the mixed grass prairie ... [that] encompasses a wide variety of wetland, riparian, grassland, and forested habitats". By one estimate there are more than of Rocky Mountain Front land in Montana and Canada. The Rocky Mountain Front is such an important geologic feature that it affects the weather in North America. Warm air masses moving from the Gulf of Mexico are blocked by the front from moving west, causing hail, thunderstorms, tornadoes, and other kinds of violent weather which then move east. "Tornado Alley", that part of the Great Plains where tornadoes are most frequent, is a direct outcome of the
https://en.wikipedia.org/wiki/Response%20amplitude%20operator
In the field of ship design and design of other floating structures, a response amplitude operator (RAO) is an engineering statistic, or set of such statistics, that are used to determine the likely behavior of a ship when operating at sea. Known by the acronym of RAO, response amplitude operators are usually obtained from models of proposed ship designs tested in a model basin, or from running specialized CFD computer programs, often both. RAOs are usually calculated for all ship motions and for all wave headings. Usage RAOs are effectively transfer functions used to determine the effect that a sea state will have upon the motion of a ship through the water, and therefore, for example, whether or not (in the case of cargo vessels) the addition of cargo to the vessel will require measures to be taken to improve stability and prevent the cargo from shifting within the vessel. Generation of extensive RAOs at the design phase allows shipbuilders to determine the modifications to a design that may be required for safety reasons (i.e., to make the design robust and resistant to capsizing or sinking in highly adverse sea conditions) or to improve performance (e.g., improve top speed, fuel consumption, stability in rough seas). RAOs are computed in tandem with the generation of a hydrodynamic database, which is a model of the effects of water pressure upon the ship's hull under a wide variety of flow conditions. Together, the RAOs and hydrodynamic database provide (inasmuch as thi

Abi Branning is a fictional character from the BBC soap opera EastEnders, played by Lorna Fitzgerald. She was introduced by executive producer Kate Harwood on 3 July 2006 as an extension to the Branning family, along with father Max (Jake Wood), mother Tanya Branning (Jo Joyner) and older sister Lauren Branning (Madeline Duggan/Jacqueline Jossa). Her storylines involve her friendships and relationships with Ben Mitchell (Charlie Jones/Joshua Pascoe/Harry Reid) and Jay Brown (Jamie Borthwick), her toxic friendship with Babe Smith (Annette Badland), faking a pregnancy so that Ben would not leave her for Paul Coker (Jonny Labey), being a suspect in the murder of Lucy Beale (Hetti Bywater), her affair with Lauren's fiancé, Steven Beale (Aaron Sidwell), and falling pregnant by him. In September 2017, it was announced that Fitzgerald and Jossa had been axed by executive consultant John Yorke. Abi's exit storyline involved her and Lauren falling from the roof of The Queen Victoria public house on Christmas Day 2017, leading to Abi giving birth prematurely to daughter, also named Abi, and being confirmed brainstem dead in later episodes. Abi's final scenes aired on 19 January 2018 after her life support is withdrawn. The character's funeral took place on 16 February 2018. For her portrayal as Abi, Fitzgerald was nominated for Best Young Actor at the 2010 Inside Soap Awards, and went on to win Best Dramatic Performance from a Young Actor or Actress at the 2012 British Soap Awards.

Nigericin is an antibiotic derived from Streptomyces hygroscopicus. Its isolation was described in the 1950s, and in 1968 the structure could be elucidated by X-ray crystallography. The structure and properties of nigericin are similar to the antibiotic monensin. Commercially it is obtained as a byproduct, or contaminant, at the fermentation of Geldanamycin. It is also called Polyetherin A, Azalomycin M, Helixin C, Antibiotic K178, Antibiotic X-464. Nigericin acts as an H+, K+, Pb2+ ionophore. Most commonly it is an antiporter of H+ and K+. In the past nigericin was used as an antibiotic active against gram positive bacteria. It inhibits the Golgi functions in Eukaryotic cells. Its ability to induce K+ efflux also makes it a potent activator of the NLRP3 inflammasome References External links Commercial supplier of nigericin sodium Antibiotics Ionophores Tetrahydrofurans Tetrahydropyrans Primary alcohols Lactols Hemiketals Vicinal diols Carboxylic acids Spiro compounds Ketals

In linguistic typology, object–subject–verb (OSV) or object–agent–verb (OAV) is a classification of languages, based on whether the structure predominates in pragmatically neutral expressions. An example of this would be "Oranges Sam ate." Unmarked word order Natural languages OSV is rarely used in unmarked sentences, which use a normal word order without emphasis. Most languages that use OSV as their default word order come from the Amazon basin, such as Xavante, Jamamadi, Apurinã, Warao, Kayabí and Nadëb. Here is an example from Apurinã: British Sign Language (BSL) normally uses topic–comment structure, but its default word order when topic–comment structure is not used is OSV. Marked word order Various languages allow OSV word order but only in marked sentences, which emphasise part or all of the sentence. Arabic Classical Arabic is generally VSO but allows OSV in marked sentences (ones using traditional Arabic declension). For example, Verse 5 of Al-Fatiha reads: The construction is less used in Modern Standard Arabic, which tends not to use marked sentences, and is generally absent in the colloquial varieties of Arabic, which are generally not declined and tend to observe strict SVO order. Chinese Passive constructions in Chinese follow an OSV (OAV) pattern through the use of the particle 被: English In English, object-subject-verb order is atypical but can be used for contrastive focus, as in: That car we bought at least five years ago.

https://en.wikipedia.org/wiki/Purely%20inseparable%20extension
In algebra, a purely inseparable extension of fields is an extension k ⊆ K of fields of characteristic p > 0 such that every element of K is a root of an equation of the form xq = a, with q a power of p and a in k. Purely inseparable extensions are sometimes called radicial extensions, which should not be confused with the similar-sounding but more general notion of radical extensions. Purely inseparable extensions An algebraic extension is a purely inseparable extension if and only if for every , the minimal polynomial of over F is not a separable polynomial. If F is any field, the trivial extension is purely inseparable; for the field F to possess a non-trivial purely inseparable extension, it must be imperfect as outlined in the above section. Several equivalent and more concrete definitions for the notion of a purely inseparable extension are known. If is an algebraic extension with (non-zero) prime characteristic p, then the following are equivalent: E is purely inseparable over F. For each element , there exists such that . Each element of E has minimal polynomial over F of the form for some integer and some element . It follows from the above equivalent characterizations that if (for F a field of prime characteristic) such that for some integer , then E is purely inseparable over F.

https://en.wikipedia.org/wiki/Inner%20cell%20mass
The inner cell mass (ICM) or embryoblast (known as the pluriblast in marsupials) is a structure in the early development of an embryo. It is the mass of cells inside the blastocyst that will eventually give rise to the definitive structures of the fetus. The inner cell mass forms in the earliest stages of embryonic development, before implantation into the endometrium of the uterus. The ICM is entirely surrounded by the single layer of trophoblast cells of the trophectoderm. Further development The physical and functional separation of the inner cell mass from the trophectoderm (TE) is a special feature of mammalian development and is the first cell lineage specification in these embryos. Following fertilization in the oviduct, the mammalian embryo undergoes a relatively slow round of cleavages to produce an eight-cell morula. Each cell of the morula, called a blastomere, increases surface contact with its neighbors in a process called compaction. This results in a polarization of the cells within the morula, and further cleavage yields a blastocyst of roughly 32 cells. In mice, about 12 internal cells comprise the new inner cell mass and 20 – 24 cells comprise the surrounding trophectoderm. There is variation between species of mammals as to the number of cells at compaction with bovine embryos showing differences related to compaction as early as 9-15 cells and in rabbits not until after 32 cells. There is also interspecies variation in gene expression patterns in early
https://en.wikipedia.org/wiki/DMSO%20reductase
DMSO reductase is a molybdenum-containing enzyme that catalyzes reduction of dimethyl sulfoxide (DMSO) to dimethyl sulfide (DMS). This enzyme serves as the terminal reductase under anaerobic conditions in some bacteria, with DMSO being the terminal electron acceptor. During the course of the reaction, the oxygen atom in DMSO is transferred to molybdenum, and then reduced to water. DMSO reductase (DMSOR) and other members of the DMSO reductase family are unique to bacteria and archaea. Enzymes of this family in anaerobic oxidative phosphorylation and inorganic-donor-based lithotrophic respiration. These enzymes have been engineered to degrade oxoanions. DMSOR catalyzes the transfer of two electrons and one oxygen atom in the reaction: The active site of DMSOR contains molybdenum, which is otherwise rare in biology. Tertiary structure and active site As for other members of DMSO reductase family, the tertiary structure of DMSOR is composed of Mo-surrounding domains I-IV, with domain IV heavily interacting with pyranopterindithiolene Mo-cofactors (P- and Q-pterin) of the active site. Members of the DMSO reductase family differ in terms of their active sites. In the case of DMSOR, the Mo center is found to two dithiolene provided by two pyranopterin cofactors. These organic cofactors, called molybdopterins, are linked to GMP to create a dinucleotide form. An additional fifth cap-like ligand is the side-chain O of serine-147 residue, further classifying the enzyme as Type III

Crystal structure Promethium oxide exists in three major crystalline forms: *a, b and c are lattice parameters, Z is the number of formula units per unit cell, density is calculated from X-ray data. The low-temperature cubic form converts to the monoclinic structure upon heating to 750–800 °C, and this transition can only be reversed by melting the oxide. The transition from the monoclinic to hexagonal form occurs at 1740 °C. References Promethium compounds Sesquioxides

https://en.wikipedia.org/wiki/Crna%20River%20%28Vardar%29
The Crna River (, "Black River"), traditionally known in English as the Cerna, is a river in North Macedonia. It is the right tributary of the Vardar River. It runs through much of the south and west of the country. Its source is in the mountains on the western part of North Macedonia, northwest of Demir Hisar. It enters the Pelagonia valley at the village of Buchin and then flows through the village Sopotnica, and southwards through the plains east of Bitola. At Brod (Novaci Municipality) it turns northeast. It leaves the Pelagonia valley at the Staravina village and goes in the biggest canyon in North Macedonia, the Skočivir valley and flows into the Vardar River between Rosoman and Gradsko. Thus, the river makes a bend of almost 180 degrees east of Bitola. This bend was part of the Macedonian front in World War I. It was known to the allied forces as the Cerna Bend or Cerna Loop, and two major battles were fought here: the Battle of the Cerna Bend (1916) and the Battle of the Crna Bend (1917). The name Crna Reka means "Black River" in Macedonian, a translation of its earlier Thracian name, Erigon (), meaning "black", akin to Greek érebos, "darkness"; Armenian erek, "evening"; Old Norse røkkr, "darkness"; Gothic riqis, "darkness"; Sanskrit rájas, "night"; and Tocharian B orkamo, "dark".

BioSteel was a trademark name for a high-strength fiber-based material made of the recombinant spider silk-like protein extracted from the milk of transgenic goats, made by defunct Montreal-based company Nexia Biotechnologies, and later by the Randy Lewis lab of the University of Wyoming and Utah State University. It is reportedly 7-10 times as strong as steel if compared for the same weight, and can stretch up to 20 times its unaltered size without losing its strength properties. It also has very high resistance to extreme temperatures, not losing any of its properties within . The company had created lines of goats to produce recombinant versions of two spidroins from Nephila clavipes, the golden orb weaver, MaSp1 and MaSp2 When the female goats lactate, the milk, containing the recombinant DNA silk, was to be harvested and subjected to chromatographic techniques to purify the recombinant silk proteins. The purified silk proteins could be dried, dissolved using solvents (DOPE formation) and transformed into microfibers using wet-spinning fiber production methods. The spun fibers were reported to have tenacities in the range of 2 - 3 grams/denier and elongation range of 25-45%. The "Biosteel biopolymer" had been transformed into nanofibers and nanomeshes using the electrospinning technique.

https://en.wikipedia.org/wiki/Otter%20%28dinghy%29
Otter is a classification referring to a particular design for a two-man sailing dinghy with a glass fibre hull. Its rig consists of a main, a jib and an optional symmetric spinnaker. The hull dimensions are 11 ft 11 in length and 4 ft 10 in beam. The boat has a draft of 3 ft 6 in with the centreboard down. The sail area (main and jib) is 75 sq. ft. The class symbol is a stylised glass bubble; due to the original lightweight "cigar box cedar" construction of the prototypes, the name 'Bubble' was first used for the boat. John Baker obtained the plans for an expanded version of the boat in G.R.P. and hence renamed the boat 'Glass Bubble'. After being put into production by Baker, the name 'Otter' was adopted; coming from the river of the same name in East Devon, close to where the boat was manufactured. The Otter also handles well and can be sailed with larger crews than the two man racing crew. The boats are also incredibly easy to sail single handed as well. However, when sailing with more than two people the boat does tend to sit quite low in the water and does affect the performance of the dinghy. The Otter was originally designed by George O'Brien Kennedy for G.R.P. Moulding, and was first produced in the mid 1960s by John Baker, Kenton Forge Ltd. The production was moved at least once, with later boats being produced by Chris Clarance Marine, Shaldon, Devon. The boats were produced for at least 22 years, with at least 1173 boats being produced. The last Otter dinghies

Multidrug resistance-associated protein 6 (MRP6) also known as ATP-binding cassette sub-family C member 6 (ABCC6) and multi-specific organic anion transporter E (MOAT-E) is a protein that in humans is encoded by the ABCC6 gene. The protein encoded by the ABCC6 gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MRP subfamily which is involved in multidrug resistance. Pathology Mutations in this protein cause pseudoxanthoma elasticum (PXE). The most common mutations, R1141X and 23-29del, account for about 25% of the found mutations. Premature atherosclerosis is also associated with mutations in the ABCC6 gene, even in those without PXE. Deficiency of Abcc6 in mouse models of ischemia leads to larger infarcts, which can be rescued by Abcc6 overexpression. Location Abcc6 gene encodes an intracellular transporter associated with mitochondrial function, located in the mitochondrial-associated membrane (MAM), whereas its substrate can be located in either MAM, cytosol or ER. Abcc6 is primarily expressed in liver and kidney,.

https://en.wikipedia.org/wiki/CYP2C9
Cytochrome P450 family 2 subfamily C member 9 (abbreviated CYP2C9) is an enzyme protein. The enzyme is involved in metabolism, by oxidation, of both xenobiotics, including drugs, and endogenous compounds, including fatty acids. In humans, the protein is encoded by the CYP2C9 gene. The gene is highly polymorphic, which affects the efficiency of the metabolism by the enzyme. Function CYP2C9 is a crucial cytochrome P450 enzyme, which plays a significant role in the metabolism, by oxidation, of both xenobiotic and endogenous compounds. CYP2C9 makes up about 18% of the cytochrome P450 protein in liver microsomes. The protein is mainly expressed in liver, duodenum and small intestine. About 100 therapeutic drugs are metabolized by CYP2C9, including drugs with a narrow therapeutic index such as warfarin and phenytoin, and other routinely prescribed drugs such as acenocoumarol, tolbutamide, losartan, glipizide, and some nonsteroidal anti-inflammatory drugs. By contrast, the known extrahepatic CYP2C9 often metabolizes important endogenous compounds such as serotonin and, owing to its epoxygenase activity, various polyunsaturated fatty acids, converting these fatty acids to a wide range of biological active products. In particular, CYP2C9 metabolizes arachidonic acid to the following eicosatrienoic acid epoxide (EETs) stereoisomer sets: 5R,6S-epoxy-8Z,11Z,14Z-eicosatetraenoic and 5S,6R-epoxy-8Z,11Z,14Z-eicosatetraenoic acids; 11R,12S-epoxy-8Z,11Z,14Z-eicosatetraenoic and 11S,12R-epo

https://en.wikipedia.org/wiki/CYP2C19
Cytochrome P450 2C19 (abbreviated CYP2C19) is an enzyme protein. It is a member of the CYP2C subfamily of the cytochrome P450 mixed-function oxidase system. This subfamily includes enzymes that catalyze metabolism of xenobiotics, including some proton pump inhibitors and antiepileptic drugs. In humans, it is the CYP2C19 gene that encodes the CYP2C19 protein. CYP2C19 is a liver enzyme that acts on at least 10% of drugs in current clinical use, most notably the antiplatelet treatment clopidogrel (Plavix), drugs that treat pain associated with ulcers, such as omeprazole, antiseizure drugs such as mephenytoin, the antimalarial proguanil, and the anxiolytic diazepam. CYP2C19 has been annotated as (R)-limonene 6-monooxygenase and (S)-limonene 6-monooxygenase in UniProt. Function The gene encodes a member of the cytochrome P450 superfamily of enzymes. Enzymes in the CYP2C subfamily, including CYP2C19, account for approximately 20% of cytochrome P450 in the adult liver. These proteins are monooxygenases that catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum and is known to metabolize many drugs. Polymorphism within this gene is associated with variable ability to metabolize drugs. The gene is located within a cluster of cytochrome P450 genes on chromosome no.10 arm q24. CYP2C19 also possesses epoxygenase activity: it is one of the principal enzymes responsible for attack
https://en.wikipedia.org/wiki/CYP2C8
Cytochrome P4502C8 (CYP2C8) is a member of the cytochrome P450 mixed-function oxidase system involved in the metabolism of xenobiotics in the body. Cytochrome P4502C8 also possesses epoxygenase activity, i.e. it metabolizes long-chain polyunsaturated fatty acids, e.g. arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid, and Linoleic acid to their biologically active epoxides. Ligands Following is a table of selected substrates, inducers and inhibitors of 2C8. Inhibitors of CYP2C8 can be classified by their potency, such as: Strong inhibitor being one that causes at least a five-fold increase in the plasma AUC values, or more than 80% decrease in clearance. Moderate inhibitor being one that causes at least a two-fold increase in the plasma AUC values, or 50-80% decrease in clearance. Weak inhibitor being one that causes at least a 1.25-fold but less than two-fold increase in the plasma AUC values, or 20-50% decrease in clearance. Where classes of agents are listed, there may be exceptions within the class. Epoxygenase activity CYP2C8 also possesses epoxygenase activity: it is one of the principal enzymes responsible for attacking various long-chain polyunsaturated fatty acids at their double (i.e. alkene) bonds to form epoxide products that act as signaling agents. It metabolizes: 1) arachidonic acid to various epoxyeicosatrienoic acids (also termed EETs); 2) linoleic acid to 9,10-epoxy octadecenoic acids (also termed vernolic acid, linoleic acid 9:10-oxide, or

https://en.wikipedia.org/wiki/White%20test
In statistics, the White test is a statistical test that establishes whether the variance of the errors in a regression model is constant: that is for homoskedasticity. This test, and an estimator for heteroscedasticity-consistent standard errors, were proposed by Halbert White in 1980. These methods have become widely used, making this paper one of the most cited articles in economics. In cases where the White test statistic is statistically significant, heteroskedasticity may not necessarily be the cause; instead the problem could be a specification error. In other words, the White test can be a test of heteroskedasticity or specification error or both. If no cross product terms are introduced in the White test procedure, then this is a test of pure heteroskedasticity. If cross products are introduced in the model, then it is a test of both heteroskedasticity and specification bias. Testing constant variance To test for constant variance one undertakes an auxiliary regression analysis: this regresses the squared residuals from the original regression model onto a set of regressors that contain the original regressors along with their squares and cross-products. One then inspects the R2. The Lagrange multiplier (LM) test statistic is the product of the R2 value and sample size: This follows a chi-squared distribution, with degrees of freedom equal to P − 1, where P is the number of estimated parameters (in the auxiliary regression). The logic of the test is as follows

He has received various accolades, including three Crystal Simorgh, a Hafez Award, two Iran Cinema Celebration Awards and an Iran's Film Critics and Writers Association Award. Career He ranks amongst the most accomplished actors of his generation. Khosrow Shakibai was born to Colonel Ahmad Shakibāi and Ms Farideh Khātami. His father, who was an army Colonel, died from cancer when Khosrow (called Mahmoud by family and close friends) was only fourteen. Khosrow studied acting at Faculty of Fine Arts of University of Tehran. He began his stage career in 1963 and branched out his activities into film dubbing in 1968. Shakibā'í initiated his film acting in 1982 with Khatt-e Ghermez (The Red Line), directed by Masoud Kimiai. He had played in seven feature films when the film director Dariush Mehrjui offered him the title role of Hamoun, a film that over time has achieved a cult status. Shakibai's performance in Hamoun marked a turning point in his career. He received a Crystal Simorgh at Fajr International Film Festival for his portrayal of Hamoun, a literary intellectual who gradually loses his touch with reality and becomes entrapped into an obsessive and destructive conflict with his estranged wife whom he deeply loves. Shakibai played also in some major television series. He won a Crystal Phoenix for Kimiā (The Philosopher's Stone) (1994) directed by Ahmad Reza Darvish. Shakibai found also a considera
https://en.wikipedia.org/wiki/Alfred%20Burne
Alfred Higgins Burne DSO (1886–1959) was a soldier and military historian. He invented the concept of Inherent Military Probability; in battles and campaigns where there is some doubt over what action was taken, Burne believed that the action taken would be one which a trained staff officer of the twentieth century would take. Career Alfred Burne was educated at Winchester School and RMA Woolwich, before being commissioned into the Royal Artillery in 1906. He was awarded the DSO during the First World War and, during World War II, was Commandant of the 121st Officer Cadet Training Unit. He retired as a Lieutenant-Colonel. He was Military Editor of Chambers Encyclopedia from 1938 to 1957 and became an authority on the history of land warfare. He was a contributor to the Dictionary of National Biography. Burne lived in Kensington and his funeral was held at St Mary Abbots there. Inherent Military Probability Burne introduced the concept of Inherent Military Probability (IMP) to the study of military history. He himself defined it thus : My method here is to start with what appear to be undisputed facts, then to place myself in the shoes of each commander in turn, and to ask myself in each case what I would have done. This I call working on Inherent Military Probability. I then compare the resulting action with the existing record in order to see whether it discloses any incompatibility with the existing facts. If not, I then go on to the next debatable or obscure po
https://en.wikipedia.org/wiki/Enthalpy%20of%20sublimation
In thermodynamics, the enthalpy of sublimation, or heat of sublimation, is the heat required to sublimate (change from solid to gas) one mole of a substance at a given combination of temperature and pressure, usually standard temperature and pressure (STP). It is equal to the cohesive energy of the solid. For elemental metals, it is also equal to the standard enthalpy of formation of the gaseous metal atoms. The heat of sublimation is usually expressed in kJ/mol, although the less customary kJ/kg is also encountered.

https://en.wikipedia.org/wiki/Haynes%E2%80%93Shockley%20experiment
In semiconductor physics, the Haynes–Shockley experiment was an experiment that demonstrated that diffusion of minority carriers in a semiconductor could result in a current. The experiment was reported in a short paper by Haynes and Shockley in 1948, with a more detailed version published by Shockley, Pearson, and Haynes in 1949. The experiment can be used to measure carrier mobility, carrier lifetime, and diffusion coefficient. In the experiment, a piece of semiconductor gets a pulse of holes, for example, as induced by voltage or a short laser pulse. Equations To see the effect, we consider a n-type semiconductor with the length d. We are interested in determining the mobility of the carriers, diffusion constant and relaxation time. In the following, we reduce the problem to one dimension. The equations for electron and hole currents are: where the js are the current densities of electrons (e) and holes (p), the μs the charge carrier mobilities, E is the electric field, n and p the number densities of charge carriers, the Ds are diffusion coefficients, and x is position. The first term of the equations is the drift current, and the second term is the diffusion current. Derivation We consider the continuity equation: Subscript 0s indicate equilibrium concentrations. The electrons and the holes recombine with the carrier lifetime τ. We define so the upper equations can be rewritten as: In a simple approximation, we can consider the electric field to be cons

Muconate lactonizing enzymes (, muconate cycloisomerase I, cis,cis-muconate-lactonizing enzyme, cis,cis-muconate cycloisomerase, 4-carboxymethyl-4-hydroxyisocrotonolactone lyase (decyclizing), CatB, MCI, MLE, 2,5-dihydro-5-oxofuran-2-acetate lyase (decyclizing)) are involved in the breakdown of lignin-derived aromatics, catechol and protocatechuate, to citric acid cycle intermediates as a part of the β-ketoadipate pathway in soil microbes. Some bacterial species are also capable of dehalogenating chloroaromatic compounds by the action of chloromuconate lactonizing enzymes. MLEs consist of several strands which have variable reaction favorable parts therefore the configuration of the strands affect its ability to accept protons. The bacterial MLEs belong to the enolase superfamily, several structures from which are known. MLEs have an identifying structure made up of two proteins and two Magnesium ions as well as various classes depending on whether it is bacterial or eukaryotic.  The reaction mechanism that MLEs undergo are the reverse of beta-elimination in which the enolate alpha-carbon is protonated. MLEs can undergo mutations caused by a deletion of catB structural genes which can cause some bacteria to lose its functions such as the ability to grow. Additional mutations to MLEs can cause its structure and function to alter and could cause the conformation to change therefore making it an inactive enzyme that is unable to bind its substrate.

The enolase superfamily is a superfamily of enzymes, members of which catalyse a range of reactions. The enolase superfamily includes enzymes that catalyse a wide variety of reactions and performing diverse roles in metabolism. However, the reactions catalysed share the common chemical step of abstraction of a proton from a carbon adjacent to a carboxylic acid and a requirement of a divalent metal ion. This diversity of functions is in contrast to many families of enzymes whose members catalyse similar chemical reactions on different substrates. Members Enolase Mandelate racemase (MR) Muconate lactonizing enzyme (MLE) The primary sequences of MR and MLE, approximately 25% identical, are related but significantly different; whereas their three-dimensional structures are similar. The enzyme enolase has a more distant, but nevertheless clear, relationship to MLE and MR. The enolase superfamily has served as a model superfamily for understanding enzyme function and is one of the protein families under study by the Enzyme Function Initiative (EFI).

https://en.wikipedia.org/wiki/Representation%20theorem
In mathematics, a representation theorem is a theorem that states that every abstract structure with certain properties is isomorphic to another (abstract or concrete) structure. Examples Algebra Cayley's theorem states that every group is isomorphic to a permutation group. Representation theory studies properties of abstract groups via their representations as linear transformations of vector spaces. Stone's representation theorem for Boolean algebras states that every Boolean algebra is isomorphic to a field of sets. A variant, Stone's representation theorem for distributive lattices, states that every distributive lattice is isomorphic to a sublattice of the power set lattice of some set. Another variant, Stone's duality, states that there exists a duality (in the sense of an arrow-reversing equivalence) between the categories of Boolean algebras and that of Stone spaces. The Poincaré–Birkhoff–Witt theorem states that every Lie algebra embeds into the commutator Lie algebra of its universal enveloping algebra. Ado's theorem states that every finite-dimensional Lie algebra over a field of characteristic zero embeds into the Lie algebra of endomorphisms of some finite-dimensional vector space. Birkhoff's HSP theorem states that every model of an algebra A is the homomorphic image of a subalgebra of a direct product of copies of A. In the study of semigroups, the Wagner–Preston theorem provides a representation of an inverse semigroup S, as a homomorphic image of t

Moritz Werner Fenchel (; 3 May 1905 – 24 January 1988) was a mathematician known for his contributions to geometry and to optimization theory. Fenchel established the basic results of convex analysis and nonlinear optimization theory which would, in time, serve as the foundation for nonlinear programming. A German-born Jew and early refugee from Nazi suppression of intellectuals, Fenchel lived most of his life in Denmark. Fenchel's monographs and lecture notes are considered influential. Biography Early life and education Fenchel was born on 3 May 1905 in Berlin, Germany, his younger brother was the Israeli film director and architect Heinz Fenchel. Fenchel studied mathematics and physics at the University of Berlin between 1923 and 1928. He wrote his doctorate thesis in geometry (Über Krümmung und Windung geschlossener Raumkurven) under Ludwig Bieberbach. Professorship in Germany From 1928 to 1933, Fenchel was Professor E. Landau's Assistant at the University of Göttingen. During a one-year leave (on Rockefeller Fellowship) between 1930 and 1931, Fenchel spent time in Rome with Levi-Civita, as well as in Copenhagen with Harald Bohr and Tommy Bonnesen. He visited Denmark again in 1932. Professorship in exile Fenchel taught at Göttingen until 1933, when the Nazi discrimination laws led to mass-firings of Jews. Fenchel emigrated to Denmark somewhere between April and September 1933, ultimately obtaining a position at the University of Copenhagen. In December 1933, F
https://en.wikipedia.org/wiki/Lattice%20reduction
In mathematics, the goal of lattice basis reduction is to find a basis with short, nearly orthogonal vectors when given an integer lattice basis as input. This is realized using different algorithms, whose running time is usually at least exponential in the dimension of the lattice. Nearly orthogonal One measure of nearly orthogonal is the orthogonality defect. This compares the product of the lengths of the basis vectors with the volume of the parallelepiped they define. For perfectly orthogonal basis vectors, these quantities would be the same. Any particular basis of vectors may be represented by a matrix , whose columns are the basis vectors . In the fully dimensional case where the number of basis vectors is equal to the dimension of the space they occupy, this matrix is square, and the volume of the fundamental parallelepiped is simply the absolute value of the determinant of this matrix . If the number of vectors is less than the dimension of the underlying space, then volume is . For a given lattice , this volume is the same (up to sign) for any basis, and hence is referred to as the determinant of the lattice or lattice constant . The orthogonality defect is the product of the basis vector lengths divided by the parallelepiped volume; From the geometric definition it may be appreciated that with equality if and only if the basis is orthogonal. If the lattice reduction problem is defined as finding the basis with the smallest possible defect, then the problem
