Primary urethral groove | The primary urethral groove or urethral groove is a temporary linear indentation on the underside (ventral side) of the male penis during embryonic development.
In humans, it typically appears around 8 weeks of gestation and becomes closed into a normal male urethra by the 12th week. |
Bharat Bill Payment System | Bharat Bill Payment System (BBPS) is an integrated bill payment system in India offering interoperable and accessible bill payment service to customers through a network of agents of registered member as Agent Institutions (AI), enabling multiple payment modes, and providing instant confirmation of payment.National Payments Corporation of India (NPCI) functions as the authorised Bharat Bill Payment Central Unit (BBPCU), which will be responsible for setting business standards, rules and procedures for technical and business requirements for all the participants. NPCI, as the BBPCU, will also undertake clearing and settlement activities related to transactions routed through BBPS. Existing bill aggregators and banks are envisaged to work as Operating Units to provide an interoperable bill payment system, irrespective of which unit has on-boarded a particular biller. Payments may be made through the BBPS using cash, transfer cheques, and electronic modes. BBPS has also been integrated with the Unified Payments Interface (UPI) for Easy, Safe & Instant Payments through UPI enabled Smartphones. |
DNM1L | Dynamin-1-like protein is a GTPase that regulates mitochondrial fission. In humans, dynamin-1-like protein, which is typically referred to as dynamin-related protein 1 (Drp1), is encoded by the DNM1L gene and is part of the dynamin superfamily (DSP) family of proteins. |
Script (Unix) | The script command is a Unix utility that records a terminal session. It dates back to the 1979 3.0 BSD. |
Fat interesterification | In the food industry and biochemistry, interesterification (IE) is a process that rearranges the fatty acids of a fat product, typically a mixture of triglyceride. The process implies breaking and reforming the ester bonds C–O–C that connect the fatty acid chains to the glycerol hubs of the fat molecules. These reactions are performed by inorganic catalysts, yielding what is called chemical interesterification (CIE) in the industry; or by enzymes, in the so-called enzymatic interesterification (EIE).This process is typically used to adjust the physical characteristics of the fat, such as melting point and plasticity, for specific uses. It can be used, for instance, to turn oils into solid or semisolid products by combining them with other solid fats. It can also be used to prevent separation of solid fractions in palm oil and lauric fats, slow rancidification, or create oils more suitable for deep frying. |
Iterated monodromy group | In geometric group theory and dynamical systems the iterated monodromy group of a covering map is a group describing the monodromy action of the fundamental group on all iterations of the covering. A single covering map between spaces is therefore used to create a tower of coverings, by placing the covering over itself repeatedly. In terms of the Galois theory of covering spaces, this construction on spaces is expected to correspond to a construction on groups. The iterated monodromy group provides this construction, and it is applied to encode the combinatorics and symbolic dynamics of the covering, and provide examples of self-similar groups. |
Language center | In neuroscience and psychology, the term language center refers collectively to the areas of the brain which serve a particular function for speech processing and production. Language is a core system that gives humans the capacity to solve difficult problems and provides them with a unique type of social interaction. Language allows individuals to attribute symbols (e.g. words or signs) to specific concepts, and utilize them through sentences and phrases that follow proper grammatical rules. Finally, speech is the mechanism by which language is orally expressed. |
Edwards syndrome | Trisomy 18, also known as Edwards syndrome, is a genetic disorder caused by the presence of a third copy of all or part of chromosome 18. Many parts of the body are affected. Babies are often born small and have heart defects. Other features include a small head, small jaw, clenched fists with overlapping fingers, and severe intellectual disability.Most cases of trisomy 18 occur due to problems during the formation of the reproductive cells or during early development. The chance of this condition occurring increases with the mother's age. Rarely, cases may be inherited. Occasionally, not all cells have the extra chromosome, known as mosaic trisomy, and symptoms in these cases may be less severe. An ultrasound during pregnancy can increase suspicion for the condition, which can be confirmed by amniocentesis.Treatment is supportive. After having one child with the condition, the risk of having a second is typically around one percent. It is the second-most common condition due to a third chromosome at birth, after Down syndrome.Trisomy 18 occurs in around 1 in 5,000 live births. Many of those affected die before birth. Some studies suggest that more babies that survive to birth are female. Survival beyond a year of life is around 5–10%. It is named after English geneticist John Hilton Edwards, who first described the syndrome in 1960. |
GABAB receptor | GABAB receptors (GABABR) are G-protein coupled receptors for gamma-aminobutyric acid (GABA), therefore making them metabotropic receptors, that are linked via G-proteins to potassium channels. The changing potassium concentrations hyperpolarize the cell at the end of an action potential. The reversal potential of the GABAB-mediated IPSP (inhibitory postsynaptic potential) is –100 mV, which is much more hyperpolarized than the GABAA IPSP. GABAB receptors are found in the central nervous system and the autonomic division of the peripheral nervous system.The receptors were first named in 1981 when their distribution in the CNS was determined, which was determined by Norman Bowery and his team using radioactively labelled baclofen. |
Contour plowing | Contour bunding or contour farming or Contour ploughing is the farming practice of plowing and/or planting across a slope following its elevation contour lines. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy precipitation, allowing more time for the water to settle into the soil. In contour plowing, the ruts made by the plow run perpendicular rather than parallel to the slopes, generally furrows that curve around the land and are level. This method is also known for preventing tillage erosion. Tillage erosion is the soil movement and erosion by tilling a given plot of land. A similar practice is contour bunding where stones are placed around the contours of slopes. Contour ploughing has been proved to reduce fertilizer loss, power and time consumption, and wear on machines, as well as to increase crop yields and reduces soil erosion. |
Calponin | Calponin is a calcium binding protein. Calponin tonically inhibits the ATPase activity of myosin in smooth muscle. Phosphorylation of calponin by a protein kinase, which is dependent upon calcium binding to calmodulin, releases the calponin's inhibition of the smooth muscle ATPase. |
BBS9 | Bardet–Biedl syndrome 9 is a protein that in humans is encoded by the BBS9 gene.The expression of the Bardet–Biedl syndrome 9 protein is downregulated by parathyroid hormone in osteoblastic cells, and therefore, is thought to be involved in parathyroid hormone action in bones.Mutations in this gene are associated with the Bardet–Biedl syndrome. |
Alfuzosin | Alfuzosin, sold under the brand name Uroxatral among others, is a medication of the α1 blocker class. It is used to treat benign prostatic hyperplasia (BPH).As an antagonist of the α1 adrenergic receptor, it works by relaxing the muscles in the prostate and bladder neck, making urination easier. Alfuzosin was patented in 1978 and approved for medical use in 1988. It was approved in the US for benign prostatic hyperplasia in 2003. In 2020, it was the 336th-most commonly prescribed medication in the United States, with more than 700 thousand prescriptions. |
Hodges–Lehmann estimator | In statistics, the Hodges–Lehmann estimator is a robust and nonparametric estimator of a population's location parameter. For populations that are symmetric about one median, such as the Gaussian or normal distribution or the Student t-distribution, the Hodges–Lehmann estimator is a consistent and median-unbiased estimate of the population median. For non-symmetric populations, the Hodges–Lehmann estimator estimates the "pseudo–median", which is closely related to the population median. |
Simulator sickness | Simulator sickness is a subset of motion sickness that is typically experienced while playing video games from first-person perspective. It was discovered in the context of aircraft pilots who undergo training for extended periods of time in flight simulators. Due to the spatial limitations imposed on these simulators, perceived discrepancies between the motion of the simulator and that of the vehicle can occur and lead to simulator sickness. |
Burch colposuspension | The Burch colposuspension is a procedure to treat urinary incontinence due to pelvic floor relaxation. The paravaginal fascia is attached to Cooper's ligament. The purpose is to suspend the prolapsed urethra so that the urethrovesical junction and proximal urethra are replaced in the abdominal cavity. |
Eckert IV projection | The Eckert IV projection is an equal-area pseudocylindrical map projection. The length of the polar lines is half that of the equator, and lines of longitude are semiellipses, or portions of ellipses. It was first described by Max Eckert in 1906 as one of a series of three pairs of pseudocylindrical projections. Within each pair, meridians are the same whereas parallels differ. Odd-numbered projections have parallels spaced equally, whereas even-numbered projections have parallels spaced to preserve area. Eckert IV is paired with Eckert III. |

Rigid belt actuator | A rigid belt actuator, also known as a push-pull belt actuator or zipper belt actuator, is a specialized mechanical linear actuator used in push-pull and lift applications. The actuator is a belt and pinion device that forms a telescoping beam or column member to transmit traction and thrust. Rigid belt actuators can move dynamic loads up to approximately 230 pounds over about 3 feet of travel. |
Radiation intelligence | Unintentional Radiation intelligence, or RINT, is military intelligence gathered and produced from unintentional radiation created as induction from electrical wiring, usually of computers, data connections and electricity networks. |
Go-kart | A go-kart, also written as go-cart (often referred to as simply a kart), is a type of sports car, close wheeled car, open-wheel car or quadracycle. Go-karts come in all shapes and forms, from non-motorised models to high-performance racing karts.
Karting is a type of racing in which a compact four-wheel unit called a go-kart is used. In the beginning, Art Ingels invented the first go-kart in Los Angeles in 1956. |
SkELL | SkELL (abbreviation of Sketch Engine for Language Learning) is a free corpus-based web tool that allows language learners and teachers find authentic sentences for specific target words.

There are versions of SkELL for English, Russian, German, Italian, Czech and Estonian. |
ParaSail (programming language) | Parallel Specification and Implementation Language (ParaSail) is an object-oriented parallel programming language. Its design and ongoing implementation is described in a blog and on its official website.ParaSail uses a pointer-free programming model, where objects can grow and shrink, and value semantics are used for assignment. It has no global garbage collected heap. Instead, region-based memory management is used throughout. Types can be recursive, so long as the recursive components are declared optional. There are no global variables, no parameter aliasing, and all subexpressions of an expression can be evaluated in parallel. Assertions, preconditions, postconditions, class invariants, etc., are part of the standard syntax, using a Hoare-like notation. Any possible race conditions are detected at compile time. Initial design of ParaSail began in September 2009, by S. Tucker Taft. |
Tunnel construction | Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and shape of the tunnel and appropriate risk management. Tunnel construction is a subset of underground construction. |
Random polytope | In mathematics, a random polytope is a structure commonly used in convex analysis and the analysis of linear programs in d-dimensional Euclidean space Rd . Depending on use the construction and definition, random polytopes may differ. |
RGS9BP | Regulator of G protein signaling 9 binding protein is a protein that in humans is encoded by the RGS9BP gene. |
Vaginal discharge | Vaginal discharge is a mixture of liquid, cells, and bacteria that lubricate and protect the vagina. This mixture is constantly produced by the cells of the vagina and cervix, and it exits the body through the vaginal opening. The composition, amount, and quality of discharge varies between individuals and can vary throughout the menstrual cycle and throughout the stages of sexual and reproductive development. Normal vaginal discharge may have a thin, watery consistency or a thick, sticky consistency, and it may be clear or white in color. Normal vaginal discharge may be large in volume but typically does not have a strong odor, nor is it typically associated with itching or pain. While most discharge is considered physiologic or represents normal functioning of the body, some changes in discharge can reflect infection or other pathological processes. Infections that may cause changes in vaginal discharge include vaginal yeast infections, bacterial vaginosis, and sexually transmitted infections. The characteristics of abnormal vaginal discharge vary depending on the cause, but common features include a change in color, a foul odor, and associated symptoms such as itching, burning, pelvic pain, or pain during sexual intercourse. |
Dimethyl 4-(methylthio)phenyl phosphate | Dimethyl 4-(methylthio)phenyl phosphate is a chemical compound used as an insecticide and an acaricide. |
Time-varying phasor | In communication theory, time-varying phasors are used for analyzing narrow-band signals, whose signal bandwidths in the frequency domain are considerably smaller than the carrier frequency. Time-varying phasors are mostly used for analysis of frequency domain of band-pass systems. The method uses classical impulse response.In electrical power system, phasors are used for transient analysis of the power system keeping the quasi-stationary conditions. They were introduced to facilitate the computation and analysis of power systems in stationary operation. Time-varying phasors are used in dynamic analysis of a large power system. The phasor representation of sinusoidal voltages and currents is generalized to arbitrary waveforms. This mathematical transformation eliminates the 60 Hertz (Hz) carrier which is the only time-varying element in the stationary case. The longer usage of time-varying phasors in large power systems since 1920s have created many misconceptions. One of the misuses suggest that quasi-stationary models are always accurate, but only when the system dynamics are slow as compared to nominal system frequency which is usually 60 Hz.The concern to study time-varying phasors is raised to understand in-depth the fast amplitude and phase variations of emerging electrical power generator technologies. This is because current and voltage signals of latest machines may have harmonic components and they can damage the entire transmission system which is coupled with the machine. However, if we employ quasi-static model, we can accurately model AC signals by using time-varying phasors as opposed to traditional quasi-static model which supports constant voltage and current signals throughout the network. |
Single-user mode | Single-user mode is a mode in which a multiuser computer operating system boots into a single superuser. It is mainly used for maintenance of multi-user environments such as network servers. Some tasks may require exclusive access to shared resources, for example running fsck on a network share. This mode can also be used for security purposes – network services are not run, eliminating the possibility of outside interference. On some systems a lost superuser password can be changed by switching to single-user mode, but not asking for the password in such circumstances is viewed as a security vulnerability. |
Relativistic Doppler effect | The relativistic Doppler effect is the change in frequency, wavelength and amplitude of light, caused by the relative motion of the source and the observer (as in the classical Doppler effect), when taking into account effects described by the special theory of relativity. The relativistic Doppler effect is different from the non-relativistic Doppler effect as the equations include the time dilation effect of special relativity and do not involve the medium of propagation as a reference point. They describe the total difference in observed frequencies and possess the required Lorentz symmetry. |
Vienna Test System | The Vienna Test System (VTS) is a test system for computerized psychological assessments. It was developed in the 1980's by the Schuhfried Company, founded by Dr. Felix Schuhfried in 1947.
VTS allows digital psychological tests to be administered while also providing automatic and comprehensive scoring. It includes classical questionnaires and tests that can only be scored by a computer, such as time-sensitive test presentation, multi-media presentation, adaptive tests, psychomotricity, combinations of tests for specific purposes (test sets) and differentiated scoring of individual responses, |
London moment | The London moment (after Fritz London) is a quantum-mechanical phenomenon whereby a spinning superconductor generates a magnetic field whose axis lines up exactly with the spin axis.
The term may also refer to the magnetic moment of any rotation of any superconductor, caused by the electrons lagging behind the rotation of the object, although the field strength is independent of the charge carrier density in the superconductor. |
Brain (journal) | Brain: A Journal of Neurology is a peer-reviewed scientific journal of neurology, founded in 1878 by John Charles Bucknill, David Ferrier, James Crichton-Browne and John Hughlings Jackson. It is published by Oxford University Press.
The journal was edited by John Newsom-Davis from 1997 to 2004, Alastair Compston (Cambridge University) until 2013, and Dimitri Kullmann (UCL) until 2021. The current editor-in-chief is Masud Husain (University of Oxford).
According to the Journal Citation Reports, the journal has a 2021 impact factor of 15.255. |
Thrush (horse) | Thrush is a very common bacterial infection that occurs on the hoof of a horse, specifically in the region of the frog. The bacterium involved is Fusobacterium necrophorum, and occurs naturally in the animal's environment—especially in wet, muddy, or unsanitary conditions, such as an unclean stall—and grows best with low oxygen. Horses with deep clefts, or narrow or contracted heels are more at risk of developing thrush. |
Pyrimidodiazepine synthase | In enzymology, a pyrimidodiazepine synthase (EC 1.5.4.1) is an enzyme that catalyzes the chemical reaction a pyrimidodiazepine + glutathione disulfide + H2O ⇌ 6-pyruvoyltetrahydropterin + 2 glutathioneThe 3 substrates of this enzyme are pyrimidodiazepine, glutathione disulfide, and H2O, whereas its two products are 6-pyruvoyltetrahydropterin and glutathione.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with a disulfide as acceptor. The systematic name of this enzyme class is pyrimidodiazepine:glutathione-disulfide oxidoreductase (ring-opening, cyclizing). Other names in common use include PDA synthase, pyrimidodiazepine:oxidized-glutathione oxidoreductase (ring-opening,, and cyclizing). This enzyme participates in glutathione metabolism. |
Ketopantoic acid | Ketopantoic acid is the organic compound with the formula HOCH2(CH3)2CC(O)CO2H. At physiological conditions, ketopantoic acid exists as its conjugate base, ketopantoate (HOCH2(CH3)2CC(O)CO2−). |
Ogg | Ogg is a free, open container format maintained by the Xiph.Org Foundation. The authors of the Ogg format state that it is unrestricted by software patents and is designed to provide for efficient streaming and manipulation of high-quality digital multimedia. Its name is derived from "ogging", jargon from the computer game Netrek.The Ogg container format can multiplex a number of independent streams for audio, video, text (such as subtitles), and metadata. |
Enterolignan | Enterolignans are organic compounds formed by the action of gut microflora on lignans. They are thus the products of the combined action of both plants and of the animal gut. Prominent enterolignans are enterodiol and enterolactone. Enterolignans are also called "mammalian lignans", although that term is self-contradictory since mammals do not produce lignans.
.
Enterolignans have attracted intense attention because of their potential beneficial roles in nutrition. Elevated levels of enterodiol in urine are attributed consumption of tea and other lignan-rich foods. |
Attribute-based encryption | Attribute-based encryption is a generalisation of public-key encryption which enables fine grained access control of encrypted data using authorisation policies. The secret key of a user and the ciphertext are dependent upon attributes (e.g. their email address, the country in which they live, or the kind of subscription they have). In such a system, the decryption of a ciphertext is possible only if the set of attributes of the user key matches the attributes of the ciphertext.A crucial security aspect of attribute-based encryption is collusion-resistance: An adversary that holds multiple keys should only be able to access data if at least one individual key grants access. |
Mass Effect: Pinnacle Station | Mass Effect: Pinnacle Station is a downloadable content (DLC) expansion pack developed by Demiurge Studios on behalf of Mass Effect franchise creator BioWare and published by Electronic Arts for the 2007 action role-playing video game Mass Effect. Pinnacle Station was released for the Xbox 360 and Microsoft Windows on August 25, 2009. The pack follows a squad led by Commander Shepard as they undergo special operations training on Pinnacle Station, a concealed military training facility. |
Terminology for the Description of Dynamics | Terminology for the Description of Dynamics (TEDDY) aims to provide an ontology for dynamical behaviours, observable dynamical phenomena, and control elements of bio-models and biological systems in Systems Biology and Synthetic Biology. |
Diazole | Diazole refers to either one of a pair of isomeric chemical compounds with molecular formula C3H4N2, having a five-membered ring consisting of three carbon atoms and two nitrogen atoms.The two isomers are: Imidazole (1,3-diazole) Pyrazole (1,2-diazole) |
Tardive dysmentia | Tardive dysmentia is a rarely used term introduced in a 1983 paper to describe "changes in affect, activation level, and interpersonal interaction", and hypothesized to be caused by long-term exposure to neuroleptic drugs in the same way as the much better-known syndrome of tardive dyskinesia. Several papers in the following years discussed the validity of the concept, and this small literature was reviewed in a 1993 publication by M. S. Myslobodsky, who drew attention to the "possibility that the syndrome of dysmentia is composed of occasional excessive emotional reactivity, enhanced responsiveness to environmental stimuli, and indifference to or reduced awareness of the patient's abnormal involuntary movements", but concluded that the pathophysiology was uncertain. Since then, the term has fallen into disuse, receiving at most only passing mentions in the literature. |
Parallelogram law | In mathematics, the simplest form of the parallelogram law (also called the parallelogram identity) belongs to elementary geometry. It states that the sum of the squares of the lengths of the four sides of a parallelogram equals the sum of the squares of the lengths of the two diagonals. We use these notations for the sides: AB, BC, CD, DA. But since in Euclidean geometry a parallelogram necessarily has opposite sides equal, that is, AB = CD and BC = DA, the law can be stated as If the parallelogram is a rectangle, the two diagonals are of equal lengths AC = BD, so and the statement reduces to the Pythagorean theorem. For the general quadrilateral with four sides not necessarily equal, where x is the length of the line segment joining the midpoints of the diagonals. It can be seen from the diagram that x=0 for a parallelogram, and so the general formula simplifies to the parallelogram law. |
Dust storm | A dust storm, also called a sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another. |
Disk image | A disk image is a snapshot of a storage device's structure and data typically stored in one or more computer files on another storage device. Traditionally, disk images were bit-by-bit copies of every sector on a hard disk often created for digital forensic purposes, but it is now common to only copy allocated data to reduce storage space. Compression and deduplication are commonly used to reduce the size of the image file set. Disk imaging is done for a variety of purposes including digital forensics, cloud computing, system administration, as part of a backup strategy, and legacy emulation as part of a digital preservation strategy. Disk images can be made in a variety of formats depending on the purpose. Virtual disk images (such as VHD and VMDK) are intended to be used for cloud computing, ISO images are intended to emulate optical media and raw disk images are used for forensic purposes. Proprietary formats are typically used by disk imaging software. Despite the benefits of disk imaging the storage costs can be high, management can be difficult and they can be time consuming to create. |
Hand deformity | A hand deformity is a disorder of the hand that can be congenital or acquired. An example is Madelung's deformity. |
Normal space | In topology and related branches of mathematics, a normal space is a topological space X that satisfies Axiom T4: every two disjoint closed sets of X have disjoint open neighborhoods. A normal Hausdorff space is also called a T4 space. These conditions are examples of separation axioms and their further strengthenings define completely normal Hausdorff spaces, or T5 spaces, and perfectly normal Hausdorff spaces, or T6 spaces. |
Moscow Formation | The Moscow Formation is a geologic formation in New York. It preserves fossils dating back to the Givetian stage. It represents around 1.5–2 million years of constant deposition. |
GABRA2 | Gamma-aminobutyric acid receptor subunit alpha-2 is a protein in humans that is encoded by the GABRA2 gene.GABRA2 is an alpha subunit that is part of GABA-A receptors, which are ligand-gated chloride channels and are activated by the major inhibitory neurotransmitter in the mammalian brain, GABA. Chloride conductance of these channels can be modulated by agents, such as benzodiazepines (psychoactive drugs) that bind to the GABA-A receptor. |
Waltzer | A Waltzer is a flat fairground ride that often forms the centrepiece of traditional British and Irish fairs. The ride consists of a number of cars which spin freely while rotating around a central point, in much the same way as a carousel. As the cars revolve, the floor of the ride undulates over a track so that the cars rise and fall as the ride spins. The offset weight of the riders causes each car to rotate. The riders experience varying levels of g-force from the spinning of the car, and the rotation of the ride itself. Because of this, operators will impose height and age restrictions. |
Toy Manchester Terrier | The Toy Manchester Terrier is a breed of dog, categorized as a terrier. The breed was bred down in size in North America from the Manchester Terrier, and is placed in the Toy Group by the American Kennel Club and the Canadian Kennel Club (the Manchester Terrier is placed in the Terrier Group). Neither the Fédération Cynologique Internationale nor The Kennel Club recognize a Toy variety of the Manchester Terrier. |
Rexed laminae | The Rexed laminae comprise a system of ten layers of grey matter (I–X), identified in the early 1950s by Bror Rexed to label portions of the grey columns of the spinal cord.Similar to Brodmann areas, they are defined by their cellular structure rather than by their location, but the location still remains reasonably consistent. |
Level bust | A level bust, also known as an altitude deviation, occurs when an aircraft fails to fly at the level for which it has been cleared. A level bust is defined by EUROCONTROL as: "Any unauthorised vertical deviation of more than 300 feet from an ATC flight clearance." This may take one of three different forms: An aircraft in level flight climbs or descends without clearance An aircraft climbing or descending fails to level off accurately at the correct level (either passing through and continuing the climb or descent, or passing through and then returning to the correct level) An aircraft levelling off at the correct level or altitude, but with an incorrect altimeter setting |
Input–output memory management unit | In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU-visible virtual addresses to physical addresses, the IOMMU maps device-visible virtual addresses (also called device addresses or memory mapped I/O addresses in this context) to physical addresses. Some units also provide memory protection from faulty or malicious devices. |
Articulated locomotive | An articulated locomotive is a steam locomotive (rarely, an electric locomotive) with one or more engine units that can move independently of the main frame. Articulation allows the operation of locomotives that would otherwise be too large to negotiate a railroad's curves, whether mainlines or special lines with extreme curvature such as logging, industrial, or mountain railways.
Articulated locomotives saw service in many nations, but were very popular on narrow-gauge railways in Europe. The largest examples were developed in the United States, where the Union Pacific Big Boy 4-8-8-4s and the Allegheny H-8 2-6-6-6s were some of the largest steam locomotives ever built. |
Production board | A traditional production board, stripboard, or production strip is a filmmaking term for a cardboard or wooden chart displaying color-coded strips of paper, each containing information about a scene in the film's shooting script. The strips can then be rearranged and laid out sequentially to represent the order one wants to film in, providing a schedule that can be used to plan the production. This is done because most films are shot "out of sequence," meaning that they do not necessarily begin with the first scene and end with the last. For logistical purposes, scenes are often grouped by talent or location and are arranged to accommodate the schedules of cast and crew. A production board is not to be confused with a Stripboard used for electronics prototyping. |
Super-seeding | In file sharing, super-seeding is an algorithm developed by John Hoffman for the BitTorrent communications protocol that helps downloaders become uploaders more quickly, but it introduces the danger of total seeding failure if there is only one downloader.The algorithm applies when there is only one seed in the swarm. By permitting each downloader to download only specific parts of the files listed in a torrent, it allows peers to start seeding more quickly. Peers attached to a seed with super-seeding enabled therefore distribute pieces of the torrent file much more readily before they have completed the download themselves.In 2003, BitTornado became the first BitTorrent client to implement the algorithm. |
Mercury(II) acetate | Mercury(II) acetate is the chemical compound with the formula Hg(O2CCH3)2. Commonly abbreviated Hg(OAc)2, this compound is employed as a reagent to generate organomercury compounds from unsaturated organic precursors. It is a white water-soluble solid, but samples appear yellowish with time owing to decomposition. |
Indium-111 | Indium-111 (111In) is a radioactive isotope of indium (In). It decays by electron capture to stable cadmium-111 with a half-life of 2.8 days.
Indium-111 chloride (111InCl) solution is produced by proton irradiation of a cadmium target (112Cd(p,2n) or 111Cd(p,n)) in a cyclotron, as recommended by International Atomic Energy Agency (IAEA). The former method is more commonly used as it results in a high level of radionuclide purity.
Indium-111 is commonly used in nuclear medicine diagnostic imaging by radiolabeling targeted molecules or cells. During its radioactive decay, it emits low energy gamma (γ) photons which can be imaged using planar or single-photon emission computed tomography (SPECT) gamma cameras (primary energies (ε) of 171.3 keV (91%) and 245.4 keV (94%)) |
Red wine headache | Red wine headache ("RWH") is a headache often accompanied by nausea and flushing that occurs after consuming red wine in susceptible individuals. White wine headaches have been less commonly reported. |
GEORGE (programming language) | GEORGE (General Order Generator) is a programming language invented by Charles Leonard Hamblin in 1957. It was designed around a push-down pop-up stack for arithmetic operations, and employed reverse Polish notation. The language included loops, subroutines, conditionals, vectors, and matrices. |
Microwave Bypass | Microwave Bypass, Inc. launched the world's first fixed wireless internet access technology in 1987, a decade before Wi-Fi. It enabled local and remote networks to connect at the then full Ethernet (802.3) data rate of 10 megabits per second, and for up to 4.3 miles.The company was founded in March 1986 by David Theodore (25), operating from One Kendall Square, Cambridge, Massachusetts. Its wireless solution consisted of a modified broadcast quality video radio (23 GHz) coupled with Microwave Bypass' EtherWave Transceiver. The system met the then highest Ethernet throughput and could transmit 4.3 miles (6.9 km), in keeping with Ethernet's propagation delay allowance (46.4µs). |

Transverse-field Ising model | The transverse field Ising model is a quantum version of the classical Ising model. It features a lattice with nearest neighbour interactions determined by the alignment or anti-alignment of spin projections along the z axis, as well as an external magnetic field perpendicular to the z axis (without loss of generality, along the x axis) which creates an energetic bias for one x-axis spin direction over the other. |
Buckboard | A buckboard is a four-wheeled wagon of simple construction meant to be drawn by a horse or other large animal. A distinctly American utility vehicle, the buckboard has no springs between the body and the axles. The suspension is provided by the flexible floorboards of the body and a leaf spring under the seat(s). The buckboard has no sideboards on the body, leaving the floor quite mobile. In rough terrain, the floor can flex and "buck", lending the vehicle its name. |
Daddy (slang) | A daddy in gay culture is a slang term meaning an (typically) older man sexually involved in a relationship or wanting sex with a younger male. The age gap and maturity gap is key to the relationship. The term has increasingly been applied to heterosexual relationships. In addition to being older and/or more experienced, it can sometimes have connotations of submission.In the homonormative sense, a dad (or daddy) is a gay man who applies a state of mind that encompasses care, consideration, mentorship and leadership to a gay junior male. A dad is usually a cis-gendered male, but this may not always be the case. The dad has the welfare of a younger man at heart, and his natural impulse is benevolent guardianship. |
WAGR syndrome | WAGR syndrome (also known as WAGR complex, Wilms tumour-aniridia syndrome, aniridia-Wilms tumour syndrome) is a rare genetic syndrome in which affected children are predisposed to develop Wilms tumour (a tumour of the kidneys), Aniridia (absence of the coloured part of the eye, the iris), Genitourinary anomalies, and mental Retardation. The G is sometimes instead given as "gonadoblastoma," since the genitourinary anomalies can include tumours of the gonads (testes or ovaries).Some WAGR syndrome patients show severe childhood obesity and hyperphagia; the acronym WAGRO (O for obesity) has been used to describe this category and may be associated with the coinciding loss of BDNF a gene that is also on chromosome 11.The condition, first described by Miller et al. in 1964 in its association with other congenital malformations, results from a deletion on chromosome 11 resulting in the loss of several genes. As such, it is one of the best studied examples of a condition caused by loss of neighbouring (contiguous) genes.It is possible for those with WAGR syndrome to develop Wilms tumor, a rare form of kidney cancer. |
Spring Triangle | The Spring Triangle is an astronomical asterism involving an imaginary triangle drawn upon the celestial sphere, with its defining vertices at Arcturus, Spica, and Regulus. This triangle connects the constellations of Boötes, Virgo, and Leo. It is visible in the evening rising in the southeastern sky of the Northern Hemisphere between March and May and setting until August, while at morning rising and setting from November to the end of February. |
Helmet sticker | Helmet stickers, also known as reward decals and pride stickers, are stickers that are affixed to a high school or college football player's helmet. They can denote either individual or team accomplishments. |
Experiment to Detect the Global EoR Signature | The Experiment to Detect the Global EoR Signature (EDGES) is an experiment and radio telescope located in a radio quiet zone at the Murchison Radio-astronomy Observatory in Western Australia. It is a collaboration between Arizona State University and Haystack Observatory, with infrastructure provided by CSIRO. EoR stands for epoch of reionization, a time in cosmic history when neutral atomic hydrogen gas became ionised due to ultraviolet light from the first stars. |
Supramolecular chemistry | Supramolecular chemistry refers to the branch of chemistry concerning chemical systems composed of a discrete number of molecules. The strength of the forces responsible for spatial organization of the system range from weak intermolecular forces, electrostatic charge, or hydrogen bonding to strong covalent bonding, provided that the electronic coupling strength remains small relative to the energy parameters of the component. While traditional chemistry concentrates on the covalent bond, supramolecular chemistry examines the weaker and reversible non-covalent interactions between molecules. These forces include hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, pi–pi interactions and electrostatic effects.Important concepts advanced by supramolecular chemistry include molecular self-assembly, molecular folding, molecular recognition, host–guest chemistry, mechanically-interlocked molecular architectures, and dynamic covalent chemistry. The study of non-covalent interactions is crucial to understanding many biological processes that rely on these forces for structure and function. Biological systems are often the inspiration for supramolecular research. |
Arfendazam | Arfendazam (INN) is a drug which is a benzodiazepine derivative. Arfendazam is a 1,5-benzodiazepine, with the nitrogen atoms located at positions 1 and 5 of the diazepine ring, and so is most closely related to other 1,5-benzodiazepines such as clobazam. Arfendazam has sedative and anxiolytic effects similar to those produced by other benzodiazepine derivatives, but is a partial agonist at GABAA receptors, so the sedative effects are relatively mild and it produces muscle relaxant effects only at very high doses.Arfendazam produces an active metabolite lofendazam, which is thought to be responsible for part of its effects. |
MGST2 | Microsomal glutathione S-transferase 2 is an enzyme that in humans is encoded by the MGST2 gene.The MAPEG (Membrane-Associated Proteins in Eicosanoid and Glutathione metabolism) family consists of six human proteins, several of which are involved in the production of leukotrienes and prostaglandin E, important mediators of inflammation. This gene encodes a protein that catalyzes the conjugation of leukotriene A4 and reduced glutathione to produce leukotriene C4. |
Kadison–Kastler metric | In mathematics, the Kadison–Kastler metric is a metric on the space of C*-algebras on a fixed Hilbert space. It is the Hausdorff distance between the unit balls of the two C*-algebras, under the norm-induced metric on the space of all bounded operators on that Hilbert space.
It was used by Richard Kadison and Daniel Kastler to study the perturbation theory of von Neumann algebras. |
Advanced Science | Advanced Science is an interdisciplinary peer-reviewed open-access scientific journal covering fundamental and applied research in materials science, physics and chemistry, medical and life sciences, as well as engineering.

Small Payload Quick Return | Small Payload Quick Return (SPQR) is a NASA Ames Research Center concept to return small payloads from orbit.The system uses an Exo-Brake, a parachute-like drag device for use in the low-pressure exosphere of Low Earth Orbit. This is the first part of a three part return system, operating from 350 to 100 km. |
Biostatistics | Biostatistics (also known as biometry) is a branch of statistics that applies statistical methods to a wide range of topics in biology. It encompasses the design of biological experiments, the collection and analysis of data from those experiments and the interpretation of the results. |
Liver sinusoidal endothelial cell | Liver sinusoidal endothelial cells (LSECs) form the lining of the smallest blood vessels in the liver, also called the hepatic sinusoids. LSECs are highly specialized endothelial cells with characteristic morphology and function. They constitute an important part of the reticuloendothelial system (RES). |
Thermotropism | Thermotropism or thermotropic movement is the movement of an organism or a part of an organism in response to heat or changes from the environment's temperature. A common example is the curling of Rhododendron leaves in response to cold temperatures. Mimosa pudica also show thermotropism by the collapsing of leaf petioles leading to the folding of leaflets, when temperature drops.The term "thermotropism" was originated by French botanist Philippe Van Tieghem in his 1884 textbook Traité de botanique. Van Tieghem stated that a plant irradiated with an optimum growth temperature on one side laterally, and a much higher or lower temperature on the opposite side, would exhibit faster growth on the side exposed to optimum temperature.The definition of thermotropism can sometimes be confused with the term, thermotaxis, a mechanism by which temperature gradients can alter the behavior of cells, such as moving toward the cold environment. The difference between them is that thermotropism is more commonly used in botany because it could not only represent the movement in organism level, thermotropism could also represent an organ level of movement, such as movement of leaves and roots toward or away from heat; but thermotaxis can only represent locomotion at the organism level, such as the movement of a mouse away from a warm environment. |
Degenerate semiconductor | A degenerate semiconductor is a semiconductor with such a high level of doping that the material starts to act more like a metal than as a semiconductor. Unlike non-degenerate semiconductors, these kinds of semiconductor do not obey the law of mass action, which relates intrinsic carrier concentration with temperature and bandgap. |
Preventive mastectomy | A preventive mastectomy or prophylactic mastectomy or risk-reducing mastectomy (RRM) is an elective operation to remove the breasts so that the risk of breast cancer is reduced. |
Hedonic motivation | Hedonic motivation refers to the influence of a person's pleasure and pain receptors on their willingness to move towards a goal or away from a threat. This is linked to the classic motivational principle that people approach pleasure and avoid pain, and is gained from acting on certain behaviors that resulted from esthetic and emotional feelings such as: love, hate, fear, joy, etc. According to the hedonic principle, our emotional experience can be thought of as a gauge that ranges from bad to good and our primary motivation is to keep the needle on the gauge as close to good as possible. |
ACADM | ACADM (acyl-Coenzyme A dehydrogenase, C-4 to C-12 straight chain) is a gene that provides instructions for making an enzyme called acyl-coenzyme A dehydrogenase that is important for breaking down (degrading) a certain group of fats called medium-chain fatty acids.
These fatty acids are found in foods such as milk and certain oils, and they are also stored in the body's fat tissue. Medium-chain fatty acids are also produced when larger fatty acids are degraded.
The acyl-coenzyme A dehydrogenase for medium-chain fatty acids (ACADM) enzyme is essential for converting these particular fatty acids to energy, especially during periods without food (fasting). The ACADM enzyme functions in mitochondria, the energy-producing centers within cells. It is found in the mitochondria of several types of tissues, particularly the liver.
The ACADM gene is located on the short (p) arm of chromosome 1 at position 31, from base pair 75,902,302 to base pair 75,941,203. |
Aristotle's axiom | Aristotle's axiom is an axiom in the foundations of geometry, proposed by Aristotle in On the Heavens that states: If XOY^ is an acute angle and AB is any segment, then there exists a point P on the ray OY→ and a point Q on the ray OX→ , such that PQ is perpendicular to OX and PQ > AB. Aristotle's axiom is a consequence of the Archimedean property, and the conjunction of Aristotle's axiom and the Lotschnittaxiom, which states that "Perpendiculars raised on each side of a right angle intersect", is equivalent to the Parallel Postulate.Without the parallel postulate, Aristotle's axiom is equivalent to each of the following three incidence-geometric statements: Given a line a and a point P on a, as well as two intersecting lines m and n, both parallel to a, there exists a line g through P which intersects m but not n. |
Sodium-transporting carboxylic acid decarboxylase | The Na+-transporting Carboxylic Acid Decarboxylase (NaT-DC) Family (TC# 3.B.1) is a family of porters that belong to the CPA superfamily. Members of this family have been characterized in both Gram-positive and Gram-negative bacteria. A representative list of proteins belonging to the NaT-DC family can be found in the Transporter Classification Database. |
Poetic devices | Poetic devices are a form of literary device used in poetry. Poems are created out of poetic devices composite of: structural, grammatical, rhythmic, metrical, verbal, and visual elements. They are essential tools that a poet uses to create rhythm, enhance a poem's meaning, or intensify a mood or feeling. |
Wasp waist | Wasp waist is a women's fashion silhouette, produced by a style of corset and girdle, that has experienced various periods of popularity in the 19th and 20th centuries. Its primary feature is the abrupt transition from a natural-width rib cage to an exceedingly small waist, with the hips curving out below. It takes its name from its similarity to a wasp's segmented body. The sharply cinched waistline also exaggerates the hips and bust. |
Sequential access | Sequential access is a term describing a group of elements (such as data in a memory array or a disk file or on magnetic-tape data storage) being accessed in a predetermined, ordered sequence. It is the opposite of random access, the ability to access an arbitrary element of a sequence as easily and efficiently as any other at any time. |
Prostaglandin inhibitors | Prostaglandin inhibitors are drugs that inhibit the synthesis of prostaglandin in human body. There are various types of prostaglandins responsible for different physiological reactions such as maintaining the blood flow in stomach and kidney, regulating the contraction of involuntary muscles and blood vessels, and act as a mediator of inflammation and pain. Cyclooxygenase (COX) and Phospholipase A2 are the major enzymes involved in prostaglandin production, and they are the drug targets for prostaglandin inhibitors. There are mainly 2 classes of prostaglandin inhibitors, namely non- steroidal anti- inflammatory drugs (NSAIDs) and glucocorticoids. In the following sections, the medical uses, side effects, contraindications, toxicity and the pharmacology of these prostaglandin inhibitors will be discussed. |
Canon EOS 90D | The Canon EOS 90D is a digital single-lens reflex (DSLR) camera released by Canon on August 28, 2019. It has a body-only MSRP of US$1199, which is the same as the Canon EOS 80D, which it replaces.The camera is one of Canon's APS-C cameras and is referred to as an enthusiast model. The 90D has a 32.5MP image sensor. |
Thymus hyperplasia | Thymus hyperplasia refers to an enlargement ("hyperplasia") of the thymus.It is not always a disease state. The size of the thymus usually peaks during adolescence and atrophies in the following decades. Before the immune function of the thymus was well understood, the enlargement was sometimes seen as a cause for alarm, and justification for surgical reduction. This approach is much less common today. |
Abell 2147 | Abell 2147 is a galaxy cluster in the Abell catalogue. It is located within the core of the Hercules Superclusters (SCI 160), within Serpens Caput, near the cluster Abell 2152, approximately two degrees south southwest of the Hercules Cluster (Abell 2151). It is possible that Abell 2147 is actually part of the Hercules Cluster considering that it shares the same redshift of 550 million light years.This galaxy cluster contains mostly faint, small and scattered galaxies. |
Voice in the Wilderness | Voice in the Wilderness or "a lone voice in the wilderness" is an English idiom for someone who expresses an idea or opinion that is not popular or that the individual is the sole person expressing that particular opinion with the suggestion that the opinion is then ignored.
It is from the King James Bible, Matthew 3:3, Mark 1:3, Luke 3:4 John 1:23 "... voice of one crying in the wilderness ..." and Isaiah 40:3 "The voice of him that crieth in the wilderness ...". |
