Intermagnet | INTERMAGNET (the International Real-time Magnetic Observatory Network) is a world-wide consortium of institutes operating ground-based magnetometers recording the absolute level of the Earth's time-varying magnetic field, to an agreed set of standards. INTERMAGNET has its roots in discussions held at the Workshop on Magnetic Observatory Instruments in Ottawa, Canada, in August 1986 and at the Nordic Comparison Meeting in Chambon La Foret, France, in May 1987. A pilot scheme between USGS and BGS was described in the sessions of Division V of the International Association of Geomagnetism and Aeronomy at the 19th General Assembly of the International Union of Geodesy and Geophysics in Vancouver, Canada, in August 1987. This scheme used the GOES East satellite to successfully transfer geomagnetic data between the two organisations. INTERMAGNET was founded soon after in order to extend the network of observatories communicating in this way. 62 different institutes are now members of the INTERMAGNET consortium, and, since 1991, data have been contributed to INTERMAGNET from approximately 150 observatories. INTERMAGNET is a member of the World Data System of the International Science Council, and it is closely associated with the International Association of Geomagnetism and Aeronomy.INTERMAGNET is organised into an Executive Council, formed of representatives of its founding members (NRCan – Canada, IPGP – France, BGS – United Kingdom, USGS – United States of America), and an Operations Committee, formed of members from many institutes concerned with geomagnetism and with operating magnetic observatories. The Operations Committee handles applications for membership of INTERMAGNET, implements updates to the technical manual. and oversees the maintenance of standards and the annual publication of data. Intermagnet operational standards and other technical information are summarized in the technical manual. |
David W. Green (psychologist) | David Green is a professorial research fellow in the Department of Cognitive, Perceptual & Brain Sciences, an honorary senior research associate, an emeritus professor of psychology in the Division of Psychology & Language Sciences, and on the faculty of Brain Sciences at University College London. He has researched widely on subjects such as mental models, both construction and manipulation, the lexical organisation, and modelling control processes in speech production, language control particularly biliginual and the imaging of language and object recognition in the neurologically damaged. He is one of the four chief editors of the academic journal Bilingualism: Language and Cognition. |
Retinol dehydrogenase | In enzymology, a retinol dehydrogenase (RDH) (EC 1.1.1.105) is an enzyme that catalyzes the chemical reaction retinol + NAD+ ⇌ retinal + NADH + H+Sometimes, in addition to or along with NAD+, NADP+ can act as a preferred cofactor in the reaction as well. The substrate of the enzyme can be all-trans- or -cis- retinol. There are at least over 20 different isolated enzymes with RDH activity to date. Thus, the two substrates of this enzyme are retinol and NAD+, whereas its 3 products are retinal, NADH (or NADPH in the case where NADP+ is a cofactor), and H+.This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is retinol:NAD+ oxidoreductase. Other names in common use include retinol (vitamin A1) dehydrogenase, MDR, microsomal retinol dehydrogenase, all-trans retinol dehydrogenase, retinal reductase, and retinene reductase. This enzyme participates in retinol metabolism. Occasionally, the literature refers to retinol dehydrogenase as an enzyme that oxidizes retinol in general, such as class IV alcohol dehydrogenase (ADH4), which reportedly is the most efficient retinol oxidation in the human alcohol dehydrogenase (ADH) family. |
Frot | Frot or frotting (slang for frottage; from French frotter 'to rub') is a gay sexual practice that usually involves direct penis-to-penis contact. The term was popularized by gay male activists who disparaged the practice of anal sex, but has since evolved to encompass a variety of preferences for the act, which may or may not imply particular attitudes towards other sexual activities. Owing to its non-penetrative character, frot has the safe sex advantage of minimizing the transmission risk for HIV/AIDS; however, it still carries the risk of skin-to-skin sexually transmitted infections, such as HPV and pubic lice (crabs), both of which can be transmitted even when lesions are not visible.It is analogous to tribadism, which is vulva-to-vulva contact between women. |
Space tether | Space tethers are long cables which can be used for propulsion, momentum exchange, stabilization and attitude control, or maintaining the relative positions of the components of a large dispersed satellite/spacecraft sensor system. Depending on the mission objectives and altitude, spaceflight using this form of spacecraft propulsion is theorized to be significantly less expensive than spaceflight using rocket engines. |
Blood pool agent | Blood pool agents (BPAs) are a class of magnetic resonance angiography contrast agents. Blood pool agents (also known as intravascular contrast agents) are differentiated from other contrast agents due to their high molecular weight and higher relaxivities. Their large size prevents diffusion through the vascular epithelium and leakage into the interstitial space, and because of this they stay in the vascular system for a longer time period. Most contrast agents, leave the vascular system within a few minutes, however blood pool agents remain in the circulation for up to an hour, extending the window available for imaging. Longer image acquisition times allow better signal-to-noise ratio and improved image resolution. |
TRPC1 | Transient receptor potential canonical 1 (TRPC1) is a protein that in humans is encoded by the TRPC1 gene. |
MOCS3 | Adenylyltransferase and sulfurtransferase MOCS3 is an enzyme that in humans is encoded by the MOCS3 gene.Molybdenum cofactor (MoCo) is necessary for the function of all molybdoenzymes. One of the enzymes required for the biosynthesis of MoCo is molybdopterin synthase (MPT synthase, encoded by MOCS2/Mocs2 in mammals). The protein encoded by this gene adenylates and activates MPT synthase. This gene contains no introns. A pseudogene of this gene is present on chromosome 14. |
MAFless Tuning | MAFless tuning is a method of operating the fuel injection system on a gasoline-powered motor vehicle whereby the mass airflow meter, or MAF, is removed. |
Exome sequencing | Exome sequencing, also known as whole exome sequencing (WES), is a genomic technique for sequencing all of the protein-coding regions of genes in a genome (known as the exome). It consists of two steps: the first step is to select only the subset of DNA that encodes proteins. These regions are known as exons—humans have about 180,000 exons, constituting about 1% of the human genome, or approximately 30 million base pairs. The second step is to sequence the exonic DNA using any high-throughput DNA sequencing technology.The goal of this approach is to identify genetic variants that alter protein sequences, and to do this at a much lower cost than whole-genome sequencing. Since these variants can be responsible for both Mendelian and common polygenic diseases, such as Alzheimer's disease, whole exome sequencing has been applied both in academic research and as a clinical diagnostic. |
Kleinian integer | In mathematical cryptography, a Kleinian integer is a complex number of the form m+n1+−72 , with m and n rational integers. They are named after Felix Klein.
The Kleinian integers form a ring called the Kleinian ring, which is the ring of integers in the imaginary quadratic field Q(−7) . This ring is a unique factorization domain. |
Metal umlaut | A metal umlaut (aka röck döts) is a diacritic that is sometimes used gratuitously or decoratively over letters in the names of mainly hard rock or heavy metal bands—for example, those of Blue Öyster Cult, Queensrÿche, Lääz Rockit, Motörhead, the Accüsed, Mötley Crüe and the parody bands Spın̈al Tap, Green Jellÿ and Moxy Früvous. |
Personality development | Personality development encompasses the dynamic construction and deconstruction of integrative characteristics that distinguish an individual in terms of interpersonal behavioral traits. Personality development is ever-changing and subject to contextual factors and life-altering experiences. Personality development is also dimensional in description and subjective in nature. That is, personality development can be seen as a continuum varying in degrees of intensity and change. It is subjective in nature because its conceptualization is rooted in social norms of expected behavior, self-expression, and personal growth. The dominant viewpoint in personality psychology indicates that personality emerges early and continues to develop across one's lifespan. Adult personality traits are believed to have a basis in infant temperament, meaning that individual differences in disposition and behavior appear early in life, potentially before language of conscious self-representation develop. The Five Factor Model of personality maps onto the dimensions of childhood temperament. This suggests that individual differences in levels of the corresponding personality traits (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness) are present from young ages. |
Metrizable space | In topology and related areas of mathematics, a metrizable space is a topological space that is homeomorphic to a metric space. That is, a topological space (X,τ) is said to be metrizable if there is a metric d:X×X→[0,∞) such that the topology induced by d is τ.
Metrization theorems are theorems that give sufficient conditions for a topological space to be metrizable. |
Water supply network | A water supply network or water supply system is a system of engineered hydrologic and hydraulic components that provide water supply. A water supply system typically includes the following: A drainage basin (see water purification – sources of drinking water) A raw water collection point (above or below ground) where the water accumulates, such as a lake, a river, or groundwater from an underground aquifer. Raw water may be transferred using uncovered ground-level aqueducts, covered tunnels, or underground water pipes to water purification facilities. |
ASUDAS | The ASUDAS (Arizona State University Dental Anthropology System) is a reference system for collecting data on human tooth morphology and variation created by Christy G. Turner II, Christian R. Nichol, and G. Richard Scott. The ASUDAS gives detailed descriptions for common crown and root shape variants and their different degrees of expression. It also comprises a set of reference plaques illustrating dental variants as well as showing their expression levels in 3D. The ASUDAS was designed to ensure a standardized scoring procedure with minimum error in order to warrant comparability between data collected by different observers. |
TC OT 39 | TC OT 39 is a non-peptide partial agonist of the oxytocin and vasopressin V2 receptors (Ki = 147 nM and >1000 nM, respectively) and antagonist of the vasopressin V1A receptor (Ki = 330 nM). |
Choked flow | Choked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity. |
Team Xecuter | Team Xecuter is a hacker group that makes mod chips and jailbreaking game consoles. Among console hackers, who primarily consist of hobbyists testing boundaries and believe in the open-source model, Team Xecuter was controversial for selling hacking tools for profit. Console systems targeted by the group include the Nintendo Switch, Nintendo 3DS, GameCube, NES Classic Edition, PlayStation, Xbox and the Xbox 360.In September 2020, Canadian national Gary Bowser and French national Max "MAXiMiLiEN" Louarn were arrested for designing and selling "circumvention devices", specifically products to circumvent Nintendo Switch copy protection, and were named, along with Chinese citizen Yuanning Chen, in a federal indictment filed in U.S. District Court in Seattle, WA on August 20, 2020. Each of the three men named in the indictment faced 11 felony counts, including conspiracy to commit wire fraud, conspiracy to circumvent technological measures and to traffic in circumvention devices, trafficking in circumvention devices, and conspiracy to commit money laundering. Bowser handled public relations for the group, which has been in operation since "at least" 2013. By October 2021, Bowser pled guilty to conspiracy to circumvent technological measures and trafficking in circumvention devices, agreeing to pay a $4.5 million penalty and to continue to work with authorities in their continued investigation of Team Xecuter in exchange for dropping the other nine charges against him. In December, he was ordered to pay another $10 million to Nintendo. On February 10, 2022, Bowser was sentenced to 40 months in prison.Nintendo separately filed a civil lawsuit against Bowser in April 2021 related to three counts of copyright infringement, seeking damages of $2500 per trafficked device, and $150,000 for each copyright violation.Nintendo has also successfully prevailed in another lawsuit involving resellers of Team Xecuter devices, winning $2 million with a settlement. |
Shreya Tripathi | Shreya Tripathi (died 9 October 2018) was an Indian health activist. |
Sunrise equation | The sunrise equation or sunset equation can be used to derive the time of sunrise or sunset for any solar declination and latitude in terms of local solar time when sunrise and sunset actually occur. |
Acral necrosis | Acral necrosis is a symptom common in bubonic plague. The striking black discoloration of skin and tissue, primarily on the extremities ("acral"), is commonly thought to have given rise to the name "Black Death," associated both with the disease and the pandemic which occurred in the 14th century. The term in fact came from the figural sense of "black", that is ghastly, lugubrious or dreadful.Acral necrosis may be a symptom of other diseases too. It also has been observed as an adverse event related to a medical treatment.Clotting and bleeding beneath the skin cause an area of haemorrhage, the presence of red blood cells lying outside of capillaries, into the skin and subcutaneous tissue. In isolation, this is called an ecchymosis or bruise and may be the result of injury or illness. However, acral necrosis occurs when blood supply is disrupted for prolonged periods, blackening and damaging the affected area and surrounding tissue. With appropriate medical treatment, areas with acral necrosis may be successfully restored to function and lead a normal life. Untreated cases can lead to death. |
Random glucose test | A random glucose test, also known as a random blood glucose test (RBG test) or a casual blood glucose test (CBG test) is a glucose test (test of blood sugar level) on the blood of a non-fasting person. This test assumes a recent meal and therefore has higher reference values than the fasting blood glucose (FBG) test.
Most mentions of capillary blood glucose (CBG) tests refer to random, nonfasting instances thereof, but the real distinction in that term is capillary blood glucose versus venous blood glucose, arterial blood glucose, or interstitial fluid glucose; any fingerstick or optical transdermal glucose test, fasting or nonfasting, measures capillary blood glucose level. |
Apple A6X | The Apple A6X is a 32-bit system-on-a-chip (SoC) designed by Apple Inc., introduced at the launch of the 4th generation iPad on October 23, 2012. It is a high-performance variant of the Apple A6 and the last 32-bit chip Apple used on an iOS device before Apple switched to 64-bit. Apple claims the A6X has twice the CPU performance and up to twice the graphics performance of its predecessor, the Apple A5X. Software updates for the 4th generation iPad ended in 2019 with the release of iOS 10.3.4 for cellular models, thus ceasing support for this chip as it was discontinued with the release of iOS 11 in 2017. |
Back-story (production) | Back-story, in the production of consumer goods, is information about the effects of their production. |
Hendrik W. Bode Lecture Prize | The Hendrik W. Bode Lecture Prize is an award given by the IEEE Control Systems Society (CSS) to recognize distinguished contributions to control systems science or engineering. It was established in 1989, named after Hendrik W. Bode (1905–1982), a pioneer of modern control theory and system engineering, who revolutionized both the content and methodology of his chosen fields of research during his long career at Bell Labs and Harvard University. The recipient of the award gives a plenary lecture at the annual IEEE Conference on Decision and Control (CDC). The inaugural Bode Prize Lecture was delivered by Gunter Stein at the 28th IEEE CDC in Tampa, Florida, on December 15, 1989. |
Critical embankment velocity | Critical embankment velocity or critical speed, in transportation engineering, is the velocity value of the upper moving vehicle that causes the severe vibration of the embankment and the nearby ground. This concept and the prediction method was put forward by scholars in civil engineering communities before 1980 and stressed and exhaustively studied by Krylov in 1994 based on the Green function method and predicted more accurately using other methods in the following. When the vehicles such as high-speed trains or airplanes move approaching or beyond this critical velocity (firstly regarded as the Rayleigh wave speed and later obtained by sophisticated calculation or tests), the vibration magnitudes of vehicles and nearby ground increase rapidly and possibly lead to the damage to the passengers and the neighboring residents. This relevant unexpected phenomenon is called the ground vibration boom from 1997 when it was observed in Sweden for the first time.This critical velocity is similar to that of sound which results in the sonic boom. However, there are some differences in terms of the transferring medium. The critical velocity of sound just changes in a small range, although the air quality and the interaction between the jet flight and atmosphere affect the critical velocity. But the embankment including the filling layers and ground soil underneath surface is a typically random medium. Such complex soil-structure coupling vibration system may have several critical velocity values. Therefore, the critical embankment velocity belongs to the general concept, the value of which is not constant and should be acquired by calculation or experiment in accordance with certain engineerings nowadays. |
Applicative voice | The applicative voice (; abbreviated APL or APPL) is a grammatical voice that promotes an oblique argument of a verb to the core object argument. It is generally considered a valency-increasing morpheme. The Applicative is often found in agglutinative languages, such as the Bantu languages and Austronesian languages. Other examples include Nuxalk, Ubykh, and Ainu. |
SSH2 | Protein phosphatase Slingshot homolog 2 is an enzyme that in humans is encoded by the SSH2 gene.The ADF (actin-depolymerizing factor)/cofilin family (see MIM 601442) is composed of stimulus-responsive mediators of actin dynamics. ADF/cofilin proteins are inactivated by kinases such as LIM domain kinase-1 (LIMK1; MIM 601329). The SSH family appears to play a role in actin dynamics by reactivating ADF/cofilin proteins in vivo (Niwa et al., 2002).[supplied by OMIM] |
Primitive ideal | In mathematics, specifically ring theory, a left primitive ideal is the annihilator of a (nonzero) simple left module. A right primitive ideal is defined similarly. Left and right primitive ideals are always two-sided ideals.
Primitive ideals are prime. The quotient of a ring by a left primitive ideal is a left primitive ring. For commutative rings the primitive ideals are maximal, and so commutative primitive rings are all fields. |
Fried parameter | The Fried parameter or Fried's coherence length (commonly designated as r0 ) is a measure of the quality of optical transmission through the atmosphere due to random inhomogeneities in the atmosphere's refractive index. In practice, such inhomogeneities are primarily due to tiny variations in temperature (and thus density) on smaller spatial scales resulting from random turbulent mixing of larger temperature variations on larger spatial scales as first described by Kolmogorov. The Fried parameter has units of length and is typically expressed in centimeters. It is defined as the diameter of a circular area over which the rms wavefront aberration due to passage through the atmosphere is equal to 1 radian, and typical values relevant to astronomy are in the tens of centimeters depending on atmospheric conditions. For a telescope with an aperture, D , the smallest spot that can be observed is given by the telescope's Point spread function (PSF). Atmospheric turbulence increases the diameter of the smallest spot by a factor approximately D/r0 (for long exposures). As such, imaging from telescopes with apertures much smaller than r0 is less affected by atmospheric seeing than diffraction due to the telescope's small aperture. However, the imaging resolution of telescopes with apertures much larger than r0 (thus including all professional telescopes) will be limited by the turbulent atmosphere, preventing the instruments from approaching the diffraction limit. |
FL (complexity) | In computational complexity theory, the complexity class FL is the set of function problems which can be solved by a deterministic Turing machine in a logarithmic amount of memory space. As in the definition of L, the machine reads its input from a read-only tape and writes its output to a write-only tape; the logarithmic space restriction applies only to the read/write working tape. |
Glucose clamp technique | Glucose clamp technique is a method for quantifying insulin secretion and resistance. It is used to measure either how well an individual metabolizes glucose or how sensitive an individual is to insulin. |
Post (structural) | A post is a main vertical or leaning support in a structure similar to a column or pillar, the term post generally refers to a timber but may be metal or stone. A stud in wooden or metal building construction is similar but lighter duty than a post and a strut may be similar to a stud or act as a brace. In the U.K. a strut may be very similar to a post but not carry a beam. In wood construction posts normally land on a sill, but in rare types of buildings the post may continue through to the foundation called an interrupted sill or into the ground called earthfast, post in ground, or posthole construction. A post is also a fundamental element in a fence. The terms "jack" and "cripple" are used with shortened studs and rafters but not posts, except in the specialized vocabulary of shoring. |
Audiography | Audiography ("writing sound") within Indian-style filmmaking, is the audio engineering performed by the sound department of a film or TV production; this includes sound recording, editing, mixing and sound design (formerly sound effects laying) but excludes musical composition, songwriting and choreography. |
Limewater | Limewater is a saturated aqueous solution of calcium hydroxide. Calcium hydroxide, Ca(OH)2, is sparsely soluble at room temperature in water (1.5 g/L at 25 °C). "Pure" (i.e. less than or fully saturated) limewater is clear and colorless, with a slight earthy smell and an astringent/bitter taste. It is basic in nature with a pH of 12.4. |
Atmospheric railway | An atmospheric railway uses differential air pressure to provide power for propulsion of a railway vehicle. A static power source can transmit motive power to the vehicle in this way, avoiding the necessity of carrying mobile power generating equipment. The air pressure, or partial vacuum (i.e., negative relative pressure) can be conveyed to the vehicle in a continuous pipe, where the vehicle carries a piston running in the tube. Some form of re-sealable slot is required to enable the piston to be attached to the vehicle. Alternatively the entire vehicle may act as the piston in a large tube or be coupled electromagnetically to the piston. |
Statistical associating fluid theory | Statistical associating fluid theory (SAFT) is a chemical theory, based on perturbation theory, that uses statistical thermodynamics to explain how complex fluids and fluid mixtures form associations through hydrogen bonds. Widely used in industry and academia, it has become a standard approach for describing complex mixtures. Since it was first proposed in 1990, SAFT has been used in a large number of molecular-based equation of state models for describing the Helmholtz energy contribution due to association. |
Ontology merging | Ontology merging defines the act of bringing together two conceptually divergent ontologies or the instance data associated to two ontologies. This is similar to work in database merging (schema matching). This merging process can be performed in a number of ways, manually, semi automatically, or automatically. Manual ontology merging although ideal is extremely labour-intensive and current research attempts to find semi or entirely automated techniques to merge ontologies. These techniques are statistically driven often taking into account similarity of concepts and raw similarity of instances through textual string metrics and semantic knowledge. These techniques are similar to those used in information integration employing string metrics from open source similarity libraries. |
Plinthosol | Plinthosols are iron-rich soils characterized by the presence of plinthite, petroplinthite or pisoliths. |
Synnefo | Synnefo is a complete open-source cloud stack written in Python that provides Compute, Network, Image, Volume and Storage services, similar to the ones offered by AWS. Synnefo manages multiple Google Ganeti clusters at the backend that handle low-level VM operations and uses Archipelago to unify cloud storage. To boost 3rd-party compatibility, Synnefo exposes the OpenStack APIs to users.
Synnefo is being developed by GRNET (Greek Research and Technology Network), and is powering two of its public cloud services, the ~okeanos service, which is aimed towards the Greek academic community, and the ~okeanos global service, which is open for all members of the GÉANT network. |

2-Acetylpyridine | 2-Acetylpyridine is an organic compound with the formula CH3COC5H4N. It is a viscous colorless liquid that is widely used as a flavoring substance. It is found in malt and produced by the Maillard reaction and by nixtamalization. It contributes to the flavor of corn tortillas, popcorn, and beer. The compound is prepared by acylation of 2-bromopyridine via the Grignard reagent. |
Airbrush | An airbrush is a small, air-operated tool that atomizes and sprays various media, most often paint, but also ink, dye, and foundation. Spray painting developed from the airbrush and is considered to employ a type of airbrush. |
Shock therapy (psychiatry) | Shock therapy describes a set of techniques used in psychiatry to treat depressive disorder or other illnesses, by inducing seizures or other extreme brain states, or as a painful method of aversive conditioning. It was started in the 1930s. Shock therapy covers multiple forms. Two types of shock therapy are currently practiced: Electroconvulsive therapy, in which a seizure is induced in the brain, often as an intervention for major depressive disorder, mania, and catatonia. |
Section (bookbinding) | In bookbinding, a section, gathering, or signature is a group of sheets folded in half, to be worked into the binding as a unit.
The section is the basic building block of codex bindings. In Western bookbinding, sections are sewn through their folds, with the sewing thread securing each section to the one bound before it. |
Saybolt universal viscosity | Saybolt universal viscosity (SUV), and the related Saybolt FUROL viscosity (SFV), are specific standardised tests producing measures of kinematic viscosity. FUROL is an acronym for fuel and road oil. Saybolt universal viscosity is specified by the ASTM D2161. Both tests are considered obsolete to other measures of kinematic viscosity, but their results are quoted widely in technical literature. |
Icing (game) | Icing is a drinking game and Internet meme that gained prominence in 2010 in which one person conceals a bottle of Smirnoff Ice in a place in which another person will find it. Once found, they are immediately required to kneel and drink. If handing the bottle to the person, they must willingly touch the bottle, otherwise the individual attempting to ice must get on one knee and drink. Participants are encouraged to come up with elaborate ways to present the Smirnoff Ice to their targets by hiding bottles or cans in inconspicuous locations, or in situations where drinking it would be dangerous or embarrassing (e.g. before they attend a meeting). |
Optical rectenna | An optical rectenna is a rectenna (rectifying antenna) that works with visible or infrared light. A rectenna is a circuit containing an antenna and a diode, which turns electromagnetic waves into direct current electricity. While rectennas have long been used for radio waves or microwaves, an optical rectenna would operate the same way but with infrared or visible light, turning it into electricity. |
Soft-decision decoder | In information theory, a soft-decision decoder is a kind of decoding methods – a class of algorithm used to decode data that has been encoded with an error correcting code. Whereas a hard-decision decoder operates on data that take on a fixed set of possible values (typically 0 or 1 in a binary code), the inputs to a soft-decision decoder may take on a whole range of values in-between. This extra information indicates the reliability of each input data point, and is used to form better estimates of the original data. Therefore, a soft-decision decoder will typically perform better in the presence of corrupted data than its hard-decision counterpart.Soft-decision decoders are often used in Viterbi decoders and turbo code decoders. |
Ellipsoidal dome | An ellipsoidal dome is a dome (also see geodesic dome), which has a bottom cross-section which is a circle, but has a cupola whose curve is an ellipse.There are two types of ellipsoidal domes: prolate ellipsoidal domes and oblate ellipsoidal domes. A prolate ellipsoidal dome is derived by rotating an ellipse around the long axis of the ellipse; an oblate ellipsoidal dome is derived by rotating an ellipse around the short axis of the ellipse.Of small note, in reflecting telescopes the mirror is usually elliptical, so has the form of a "hollow" ellipsoidal dome. |
Samsung Galaxy Trend Lite | Samsung Galaxy Trend Lite or Samsung Galaxy Fresh is a low-end Android smartphone released by Samsung Electronics in October 2013. It has a 4-inch TFT LCD touchscreen and incorporates 3G technology. |
Concise Command Language | Concise Command Language (CCL) was the term used by Digital Equipment Corporation for the Command-line interpreter / User interface supplied on several of their computing systems; its successor was named DIGITAL Command Language (DCL).
CCL provides the user with an extensive set of terminal commands.The first system to include CCL was DEC's PDP-10. |
Timed event system | The General System has been described in [Zeigler76] and [ZPK00] with the standpoints to define (1) the time base, (2) the admissible input segments, (3) the system states, (4) the state trajectory with an admissible input segment, (5) the output for a given state.
A Timed Event System defining the state trajectory associated with the current and event segments came from the class of General System to allows non-deterministic behaviors in it [Hwang2012]. Since the behaviors of DEVS can be described by Timed Event System, DEVS and RTDEVS is a sub-class or an equivalent class of Timed Event System. |
Rotor current meter | A rotor current meter (RCM) is a mechanical current meter, an oceanographic device deployed within an oceanographic mooring measuring the flow within the world oceans to learn more about ocean currents. Many RCMs have been replaced by instruments measuring the flow by hydroacoustics, the so-called Acoustic Doppler Current Profilers. However, for instance in Fram Strait, the Alfred Wegener Institute still uses RCMs for long-term monitoring the inflow into the Arctic Ocean. |
Frequency (gene) | The frequency (frq) gene encodes the protein frequency (FRQ) that functions in the Neurospora crassa circadian clock. The FRQ protein plays a key role in circadian oscillator, serving to nucleate the negative element complex in the auto regulatory transcription-translation negative feedback-loop (TTFL) that is responsible for circadian rhythms in N. crassa. Similar rhythms are found in mammals, Drosophila and cyanobacteria. Recently, FRQ homologs have been identified in several other species of fungi. Expression of frq is controlled by the two transcription factors white collar-1 (WC-1) and white collar-2 (WC-2) that act together as the White Collar Complex (WCC) and serve as the positive element in the TTFL. Expression of frq can also be induced through light exposure in a WCC dependent manner. Forward genetics has generated many alleles of frq resulting in strains whose circadian clocks vary in period length. |
Hospital radio | Hospital radio is a form of audio broadcasting produced specifically for the in-patients of hospitals, primarily in the United Kingdom. Hospital radio has been found to be beneficial to patients, lifting their mood and aiding recovery.
There are hundreds of hospital radio stations in the UK, almost all are members of the Hospital Broadcasting Association (HBA), which was set up by stations for their mutual benefit and does not govern or run them. Hospital radio stations are staffed and managed by volunteers. |
Prime number | A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order. |
NPTN | Neuroplastin is a protein that in humans is encoded by the NPTN gene.Neuroplastin is a type I transmembrane protein belonging to the Ig superfamily. The protein is believed to be involved in cell-cell interactions or cell-substrate interactions. The alpha and beta transcripts show differential localization within the brain.In 2014, in a study led by Dr. Sylvane Desrivières, of King's College London's Institute of Psychiatry found that "teenagers who had a highly functioning NPTN gene performed better in intelligence tests" |

There are 14 unique sterication for the 7-simplex with permutations of truncations, cantellations, and runcinations. |
Accompanied combined transport | Accompanied combined transport is a form of intermodal transport, which is the movement of goods in one and the same loading unit or road vehicle, using successively two or more modes of transport without handling the goods themselves in changing modes. More specifically, accompanied combined transport is one of the two types of combined transport, which is intermodal transport where the major part of the journey is by rail, inland waterways or sea, and any initial and/or final legs carried out by road are as short as possible.Cornbined transport is said to be "accompanied" when the driver of a complete freight carrying road vehicle is accompanying that vehicle, while it is being transported using other mode of transport. This form of intermodal freight transport is relatively common in Europe. |
Costeff syndrome | Costeff syndrome, or 3-methylglutaconic aciduria type III, is a genetic disorder caused by mutations in the OPA3 gene. It is typically associated with the onset of visual deterioration (optic atrophy) in early childhood followed by the development of movement problems and motor disability in later childhood, occasionally along with mild cases of cognitive deficiency. The disorder is named after Hanan Costeff, the doctor who first described the syndrome in 1989. |
Foot and ankle surgery | Foot and ankle surgery is a sub-specialty of orthopedics and podiatry that deals with the treatment, diagnosis and prevention of disorders of the foot and ankle. Orthopaedic surgeons are medically qualified, having been through four years of college, followed by 4 years of medical school or osteopathic medical school to obtain an M.D. or D.O. followed by specialist training as a resident in orthopaedics, and only then do they sub-specialise in foot and ankle surgery. Training for a podiatric foot and ankle surgeon consists of four years of college, four years of podiatric medical school (D.P.M.), 3–4 years of a surgical residency and an optional 1 year fellowship. |
Van Buchem disease | Van Buchem disease, or hyperostosis corticalis generalisata, is an autosomal recessive skeletal disease which is characterised by uninhibited bone growth, especially in the mandible, skull and ribs.The disease was first described in 1955 by Prof. Franciscus Stephanus Petrus van Buchem, when describing two patients of the same family in Urk in the Netherlands. The cause, he found, was that the bone was produced faster than the body broke it down, making it much thicker as the patient got older. The first symptoms experienced by the affected were often deafness and paralysis of the face, caused by the growing bone pinching the nerves. This condition can be traced to a deletion on chromosome 17q. As the disease is recessive, a child will only be affected by the disease if both of the parents are carriers and the child is homozygous for the allele, meaning that they have the allele in duplicate. The gene involved is SOST, and by extension the protein involved is sclerostin. There have been attempts to relieve a patient suffering from van Buchem disease: "A large bilateral frontoparietal craniotomy and decompression of the foramen magnum resulted in almost complete relief of his symptoms." |
Quadruple-precision floating-point format | In computing, quadruple precision (or quad precision) is a binary floating point–based computer number format that occupies 16 bytes (128 bits) with precision at least twice the 53-bit double precision. |
Pancake die | A pancake die is a simple type of manufacturing die that performs blanking or piercing. Many dies perform complex procedures simultaneously (or progressively for progressive die) such as coining, piercing, forming, bending in addition to product removal and transport (for additional manufacturing procedures or packaging). A pancake die may only perform one simple procedure with the finish product being removed by hand. |

It was initially published in 1997 as a logical data model for architecture data. |
Tittle | A tittle or superscript dot is a small distinguishing mark, such as a diacritic in the form of a dot on a letter (for example, lowercase i or j). The tittle is an integral part of the glyph of i and j, but diacritic dots can appear over other letters in various languages. In most languages, the tittle of i or j is omitted when a diacritic is placed in the tittle's usual position (as í or ĵ), but not when the diacritic appears elsewhere (as į, ɉ). |
Genetix (comics) | Genetix is a team of superheroes appearing in American comic books published by Marvel Comics, under the Marvel UK imprint. The team was created by Andy Lanning, Graham Marks, and Phil Gascoine. |
Altezza lights | Altezza lights (also known as Lexus lights, Euro lights, crystal lights, or clear lights) are vehicle tail lamp clusters consisting of one or more internal lamp units, covered with a clear (or tinted) acrylic cover. This style of taillight was made popular by Lexus and has been stock equipment on Toyota Altezza, Lexus IS300 and IS200 models since 1998. Some Altezza lights also use LED lighting. |
Sepsis | Sepsis (septicaemia in British English), or blood poisoning, is a potentially life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs.This initial stage of sepsis is followed by suppression of the immune system. Common signs and symptoms include fever, increased heart rate, increased breathing rate, and confusion. There may also be symptoms related to a specific infection, such as a cough with pneumonia, or painful urination with a kidney infection. The very young, old, and people with a weakened immune system may have no symptoms of a specific infection, and the body temperature may be low or normal instead of having a fever. Severe sepsis causes poor organ function or blood flow. The presence of low blood pressure, high blood lactate, or low urine output may suggest poor blood flow. Septic shock is low blood pressure due to sepsis that does not improve after fluid replacement.Sepsis is caused by many organisms including bacteria, viruses and fungi. Common locations for the primary infection include the lungs, brain, urinary tract, skin, and abdominal organs. Risk factors include being very young or old, a weakened immune system from conditions such as cancer or diabetes, major trauma, and burns. Previously, a sepsis diagnosis required the presence of at least two systemic inflammatory response syndrome (SIRS) criteria in the setting of presumed infection. In 2016, a shortened sequential organ failure assessment score (SOFA score), known as the quick SOFA score (qSOFA), replaced the SIRS system of diagnosis. qSOFA criteria for sepsis include at least two of the following three: increased breathing rate, change in the level of consciousness, and low blood pressure. Sepsis guidelines recommend obtaining blood cultures before starting antibiotics; however, the diagnosis does not require the blood to be infected. Medical imaging is helpful when looking for the possible location of the infection. Other potential causes of similar signs and symptoms include anaphylaxis, adrenal insufficiency, low blood volume, heart failure, and pulmonary embolism.Sepsis requires immediate treatment with intravenous fluids and antimicrobials. Ongoing care often continues in an intensive care unit. If an adequate trial of fluid replacement is not enough to maintain blood pressure, then the use of medications that raise blood pressure becomes necessary. Mechanical ventilation and dialysis may be needed to support the function of the lungs and kidneys, respectively. A central venous catheter and an arterial catheter may be placed for access to the bloodstream and to guide treatment. Other helpful measurements include cardiac output and superior vena cava oxygen saturation. People with sepsis need preventive measures for deep vein thrombosis, stress ulcers, and pressure ulcers unless other conditions prevent such interventions. Some people might benefit from tight control of blood sugar levels with insulin. The use of corticosteroids is controversial, with some reviews finding benefit, and others not.Disease severity partly determines the outcome. The risk of death from sepsis is as high as 30%, while for severe sepsis it is as high as 50%, and septic shock 80%. Sepsis affected about 49 million people in 2017, with 11 million deaths (1 in 5 deaths worldwide). In the developed world, approximately 0.2 to 3 people per 1000 are affected by sepsis yearly, resulting in about a million cases per year in the United States. Rates of disease have been increasing. Some data indicate that sepsis is more common among males than females, however, other data show a greater prevalence of the disease among women. Descriptions of sepsis date back to the time of Hippocrates. |
Wason selection task | The Wason selection task (or four-card problem) is a logic puzzle devised by Peter Cathcart Wason in 1966. It is one of the most famous tasks in the study of deductive reasoning. An example of the puzzle is: You are shown a set of four cards placed on a table, each of which has a number on one side and a color on the other. The visible faces of the cards show 3, 8, blue and red. Which card(s) must you turn over in order to test that if a card shows an even number on one face, then its opposite face is blue? A response that identifies a card that need not be inverted, or that fails to identify a card that needs to be inverted, is incorrect. The original task dealt with numbers (even, odd) and letters (vowels, consonants). |
DTVPal | The DTVPal was a line of digital-to-analog converter boxes designed by Echostar Corporation, sister company to Dish Network Corporation. The boxes were marketed starting in 2008.The units debuted to both love and criticism from purchasers, primarily related to reliability, warranty, and service issues. All models in the line were discontinued. One model, the DTVPal DVR, had unique features in this class of product: the ability to pause live TV and time-shift broadcast TV digitally. This model returned to production in 2010 as the Channel Master model CM 7000PAL. |
N-Methylhydroxylamine | N-Methylhydroxylamine or methylhydroxylamine is a hydroxylamine derivative with a methyl group replacing one of the hydrogens of the amino group. It is an isomer of methoxyamine and aminomethanol. It decomposes in an exothermic reaction (-63 kJ/mol) into methane and azanone unless stored as a hydrochloride salt.
The compound is commercially available as its hydrochloride salt. This can be produced by electrochemical reduction of nitromethane in hydrochloric acid using a copper anode and a graphite cathode. |
Apricitabine | Apricitabine (INN, codenamed AVX754 and SPD754, sometimes abbreviated to ATC) is an experimental nucleoside reverse transcriptase inhibitor (NRTI) against HIV. It is structurally related to lamivudine and emtricitabine, and, like these, is an analogue of cytidine. |
20-pair colour code (Australia) | The 20-pair colour code is a colour code used in Australia to identify individual conductors in a kind of electrical telecommunication wiring for indoor use, known as twisted pair cables. The colours are applied to the insulation that covers each conductor. The first colour is chosen from one group of five colours.
The combinations are also shown in the table below showing the colour for each wire ("1" and "2") and the pair number. |
Calcitroic acid | Calcitroic acid (1α-hydroxy-23-carboxy-24,25,26,27-tetranorvitamin D3) is a major metabolite of 1α,25-dihydroxyvitamin D3 (calcitriol). Often synthesized in the liver and kidneys, calcitroic acid is generated in the body after vitamin D is first converted into calcitriol, an intermediate in the fortification of bone through the formation and regulation of calcium in the body. These pathways managed by calcitriol are thought to be inactivated through its hydroxylation by the enzyme CYP24A1, also called calcitriol 24-hydroxylase. Specifically, It is thought to be the major route to inactivate vitamin D metabolites.Hydroxylation and further metabolism of calcitriol in the liver and the kidneys yields calcitroic acid, a water-soluble compound that is excreted in bile.In case where a higher concentration of this acid is used in vitro, studies determined that calcitroic acid binds to vitamin D receptor (VDR) and induces gene transcription.The compound has been prepared in the laboratory. |
Steering kickback | Steering kickback relates to the sharp and rapid movements of an automobile's steering wheel as the front wheels encounter a significant obstruction or imperfection in the road. The amount of kickback is dependent on a variety of factors, namely the angle of impact with the obstruction or imperfection, health and stiffness of the vehicle's shock absorbers, and the speed of the vehicle, as well as the type of steering mechanism used and its mechanical advantage. |
Symphony No. 1 (Tippett) | The Symphony No. 1 by the British composer Michael Tippett was completed in 1945. |
Chinese units of measurement | Chinese units of measurement, known in Chinese as the shìzhì ("market system"), are the traditional units of measurement of the Han Chinese. Although Chinese numerals have been decimal (base-10) since the Shang, several Chinese measures use hexadecimal (base-16). Local applications have varied, but the Chinese dynasties usually proclaimed standard measurements and recorded their predecessor's systems in their histories. In the present day, the People's Republic of China maintains some customary units based upon the market units but standardized to round values in the metric system, for example the common jin or catty of exactly 500 g. The Chinese name for most metric units is based on that of the closest traditional unit; when confusion might arise, the word "market" (市, shì) is used to specify the traditional unit and "common" or "public" (公, gōng) is used for the metric value. Taiwan, like Korea, saw its traditional units standardized to Japanese values and their conversion to a metric basis, such as the Taiwanese ping of about 3.306 m2 based on the square ken. The Hong Kong SAR continues to use its traditional units, now legally defined based on a local equation with metric units. For instance, the Hong Kong catty is precisely 604.78982 g. |
Interchalcogen | The chalcogens react with each other to form interchalcogen compounds.Although no chalcogen is extremely electropositive, nor quite as electronegative as the halogen fluorine (the most electronegative element), there is a large difference in electronegativity between the top (oxygen = 3.44 — the second most electronegative element after fluorine) and bottom (polonium = 2.0) of the group. Combined with the fact that there is a significant trend towards increasing metallic behaviour while descending the group (oxygen is a gaseous nonmetal, while polonium is a silvery post-transition metal), this causes the interchalcogens to display many different kinds of bonding: covalent, ionic, metallic, and semimetallic. |

Pirani gauge | The Pirani gauge is a robust thermal conductivity gauge used for the measurement of the pressures in vacuum systems. It was invented in 1906 by Marcello Pirani.Marcello Stefano Pirani was a German physicist working for Siemens & Halske which was involved in the vacuum lamp industry. In 1905 their product was tantalum lamps which required a high vacuum environment for the filaments. The gauges that Pirani was using in the production environment were some fifty McLeod gauges, each filled with 2 kg of mercury in glass tubes.Pirani was aware of the gas thermal conductivity investigations of Kundt and Warburg (1875) published thirty years earlier and the work of Marian Smoluchowski (1898). In 1906 he described his "directly indicating vacuum gauge" that used a heated wire to measure vacuum by monitoring the heat transfer from the wire by the vacuum environment. |
