KCNV2 | Potassium voltage-gated channel subfamily V member 2 is a protein that in humans is encoded by the KCNV2 gene. The protein encoded by this gene is a voltage-gated potassium channel subunit. |
Unthought known | Unthought known is a phrase coined by Christopher Bollas in the 1980s to represent those experiences in some way known to the individual, but about which the individual is unable to think. At its most compelling, the unthought known stands for those early schemata for interpreting the object world that preconsciously determine our subsequent life expectations. In this sense, the unthought known refers to preverbal, unschematised early experience/trauma that may determine one's behaviour unconsciously, barred to conscious thought. |
Parabidiminished rhombicosidodecahedron | In geometry, the parabidiminished rhombicosidodecahedron is one of the Johnson solids (J80). It is also a canonical polyhedron. |
Partition (number theory) | In number theory and combinatorics, a partition of a non-negative integer n, also called an integer partition, is a way of writing n as a sum of positive integers. Two sums that differ only in the order of their summands are considered the same partition. (If order matters, the sum becomes a composition.) For example, 4 can be partitioned in five distinct ways: 4 3 + 1 2 + 2 2 + 1 + 1 1 + 1 + 1 + 1The only partition of zero is the empty sum, having no parts. |
Desert bloom | A desert bloom is a climatic phenomenon that occurs in various deserts around the world. The phenomenon consists of the blossoming of a wide variety of flowers during early-mid spring in years when rainfall is unusually high. The blossoming occurs when the unusual level of rainfall reaches seeds and bulbs that have been in a latent or dormant state, and causes them to germinate and flower in early spring. It is accompanied by the proliferation of insects, birds and small species of lizards. |
European Conference on the Dynamics of Molecular Systems | MOLEC, the European Conference on the Dynamics of Molecular Systems, is a biannual scientific conference. It is held every two years usually late summer. The first conference was held in Trento, Italy in the year of 1976. |
Serous membrane | The serous membrane (or serosa) is a smooth tissue membrane of mesothelium lining the contents and inner walls of body cavities, which secrete serous fluid to allow lubricated sliding movements between opposing surfaces. The serous membrane that covers internal organs is called a visceral membrane; while the one that covers the cavity wall is called the parietal membrane. Between the two opposing serosal surfaces is often a potential space, mostly empty except for the small amount of serous fluid.The Latin anatomical name is tunica serosa. Serous membranes line and enclose several body cavities, also known as serous cavities, where they secrete a lubricating fluid which reduces friction from movements. Serosa is entirely different from the adventitia, a connective tissue layer which binds together structures rather than reducing friction between them. The serous membrane covering the heart and lining the mediastinum is referred to as the pericardium, the serous membrane lining the thoracic cavity and surrounding the lungs is referred to as the pleura, and that lining the abdominopelvic cavity and the viscera is referred to as the peritoneum. |
Inferior cerebral veins | The inferior cerebral veins are veins that drain the undersurface of the cerebral hemispheres and empty into the cavernous and transverse sinuses.
Those on the orbital surface of the frontal lobe join the superior cerebral veins, and through these open into the superior sagittal sinus.
Those of the temporal lobe anastomose with the middle cerebral and basal veins, and join the cavernous, sphenoparietal, and superior petrosal sinuses. |
Preference learning | Preference learning is a subfield in machine learning, which is a classification method based on observed preference information. In the view of supervised learning, preference learning trains on a set of items which have preferences toward labels or other items and predicts the preferences for all items.
While the concept of preference learning has been emerged for some time in many fields such as economics, it's a relatively new topic in Artificial Intelligence research. Several workshops have been discussing preference learning and related topics in the past decade. |
Bus SCS | SCS is an acronym for "Sistema Cablaggio Semplificato" ("Simplified Cable Solution"). It uses a fieldbus network protocol and has applications in the field of home automation and building automation. It is used mainly in bTicino and Legrand installations. |
BitVault | BitVault is a content-addressable distributed storage system, developed by Microsoft Research in China. BitVault uses peer-to-peer technology to distribute the tasks of storing and managing data. As such, there is no central authority responsible for management of the system. Rather, it is self-managing, provides high availability, reliability and scales up in a self-organizing manner, with low administrative overhead, which is almost constant irrespective of the size of the distributed overlay network. |
Joint European Master in Space Science and Technology | The Joint European Master in Space Science and Technology (or short SpaceMaster) is an Erasmus Mundus 120 ECTS master programme. The SpaceMaster programme started in 2005 and it is focused on providing education in Space Science and Technology to its students. The main objective of the Course is to combine the great diversity of space expertise at multiple European universities to a common platform of competence within the guidelines of the Bologna process. The educational cooperation is supported by scientific and industrial organisations, thus providing direct contacts with professional research and industry. |
Cotton maturity | Cotton maturity is a physical testing parameter of cotton fiber properties testing. It is quantified by the degree of cell wall thickening relative to its perimeter. The maturity of individual cotton fiber is an essential aspect of the cotton classing regarding the aesthetics such as appearance, dye-uptake, etc. High volume instrument (HVI) can test cotton maturity like many other fiber properties, including length, uniformity, micronaire/fineness, strength, color, etc. |
Genetics of synesthesia | The genetic mechanism of synesthesia has long been debated, with researchers previously claiming it was a single X-linked trait due to seemingly higher prevalence in women and no evidence of male-male transmission This is where the only synesthetic parent is male and the male child has synesthesia, meaning that the trait cannot be solely linked to the X chromosome. |
Viseme | A viseme is any of several speech sounds that look the same, for example when lip reading (Fisher 1968). |
Cellular algebra | In abstract algebra, a cellular algebra is a finite-dimensional associative algebra A with a distinguished cellular basis which is particularly well-adapted to studying the representation theory of A. |

Kendall's W | Kendall's W (also known as Kendall's coefficient of concordance) is a non-parametric statistic for rank correlation. It is a normalization of the statistic of the Friedman test, and can be used for assessing agreement among raters and in particular inter-rater reliability. Kendall's W ranges from 0 (no agreement) to 1 (complete agreement). |
HRDetect | HRDetect (Homologous Recombination Deficiency Detect) is a whole-genome sequencing (WGS)-based classifier designed to predict BRCA1 and BRCA2 deficiency based on six mutational signatures. Additionally, the classifier is able to identify similarities in mutational profiles of tumors to that of tumors with BRCA1 and BRCA2 defects, also known as BRCAness. This classifier can be applied to assess the implementation of PARP inhibitors in patients with BRCA1/BRCA2 deficiency. The final output is a probability of BRCA1/2 mutation. |
Karen Spärck Jones Award | To commemorate the achievements of Karen Spärck Jones, the Karen Spärck Jones Award was created in 2008 by the British Computer Society (BCS) and its Information Retrieval Specialist Group (BCS IRSG), which is sponsored by Microsoft Research.The winner of the award is invited to present a keynote talk at the European Conference on Information Retrieval (ECIR) the following year. |
Sharkskin | Sharkskin describes a specific woven or warp-knitted fabric with a distinctive sheen. Sharkskin is a twill weave fabric. Materials used in its construction include: acetate, rayon, worsted wool, lycra, and other plastic fibers. In sharkskin, the arrangement of darker and brighter threads in a twill weave creates a subtle pattern of lines that run across the fabric diagonally and a two tone, lustrous appearance. Primarily a suiting material, the fabric is sometimes seen in light jackets and non-fashion items such as curtains, tablecloths, and as a liner in diving suits and wetsuits. |
Generation ship | A generation ship, or generation starship, is a hypothetical type of interstellar ark starship that travels at sub-light speed. Since such a ship might require hundreds to thousands of years to reach nearby stars, the original occupants of a generation ship would grow old and die, leaving their descendants to continue traveling. |
Customer communications management | Customer Communications Management (CCM) is a software that enables companies to manage customer communications across a wide range of media. Originally, customer communications referred to printed documents, archived digital documents, email and web pages. It has grown to include SMS/MMS, in-app notifications, responsive design mobile experiences, and messages over common social media platforms. It entails an automated process that involves not only the delivery of communication, but also the segmentation of messages according to different customer profiles and contexts. |
Acer Chromebook Tab 10 | The Acer Chromebook Tab 10 (D651N) is a tablet computer manufactured by Acer Inc. It is the first ChromeOS tablet that was released. It gets software updates until 2023. The tablet was announced in March 2018. |
Serial Data Transport Interface | Serial Data Transport Interface is a way of transmitting data packets over a Serial Digital Interface datastream. This means that standard SDI infrastructure can be used.
Developed to address the needs of the growing number of compressed video standards (DV, DVCPRO, BetaSX, MPEG2) it allows lossless transfer of data to other devices which have the same codec, for example DV to DV or SX to SX.
Using a standard SDI transport, the extra data is placed within normal active video, between Start of Active Video (SAV), and End of Active Video (EAV). This gives 1440 10bit words of data at 270Mbit/s (1920 words in the 8bit 360Mbit/s standard).
If an SDTI stream is viewed using a standard SDI device, then the raw data can be seen as a small strip along the left hand side (usually in purple). The DVCAM SDTI has video data at the top, control data in the middle (Timecode, etc.) and audio at the bottom just like it is organised on the tape.
Because SDTI is used for compressed data the area used is less than a full screen; this allows for faster than realtime transfers.
SDTI is standardized as SMPTE 305M. A 1.5 GBit/s version, using the high definition serial digital interface, is standardized as SMPTE 348M. |
Shapeshifters (board game) | Shapeshifters is a board game that was published by Fat Messiah Games in 1991. |
Landau–Squire jet | In fluid dynamics, Landau–Squire jet or Submerged Landau jet describes a round submerged jet issued from a point source of momentum into an infinite fluid medium of the same kind. This is an exact solution to the incompressible form of the Navier-Stokes equations, which was first discovered by Lev Landau in 1944 and later by Herbert Squire in 1951. The self-similar equation was in fact first derived by N. A. Slezkin in 1934, but never applied to the jet. Following Landau's work, V. I. Yatseyev obtained the general solution of the equation in 1950. |
Sky Broadband | Sky Broadband is a broadband service offered by Sky UK in the United Kingdom. With the introduction of Sky Fibre, Sky Broadband now refers to ADSL broadband products. |
Chemical depilatory | A chemical depilatory is a cosmetic preparation used to remove hair from the skin. Common active ingredients are salts of thioglycolic acid and thiolactic acids. These compounds break the disulfide bonds in keratin and also hydrolyze the hair so that it is easily removed. Formerly, sulfides such as strontium sulfide were used, but due to their unpleasant odor, they have been replaced by thiols.The main chemical reaction effected by the thioglycolate is: 2 HSCH2CO2H (thioglycolic acid) + R-S-S-R (cystine) → HO2CCH2-S-S-CH2CO2H (dithiodiglycolic acid) + 2 RSH (cysteine)Chemical depilatories contain 5–6% calcium thioglycolate in a cream base (to avoid runoff). Calcium hydroxide or strontium hydroxide maintain a pH of about 12. Hair destruction requires about 10 minutes. Depilation is followed by careful rinsing with water, and various conditioners are applied to restore the skin's pH to normal. Depilation does not destroy the dermal papilla, and the hair grows back.Chemical depilatories are available in gel, cream, lotion, aerosol, roll-on, and powder forms. Common brands include Nair, Magic Shave, and Veet. |
BibSonomy | BibSonomy is a social bookmarking and publication-sharing system. It aims to integrate the features of bookmarking systems as well as team-oriented publication management. BibSonomy offers users the ability to store and organize their bookmarks and publication entries and supports the integration of different communities and people by offering a social platform for literature exchange.
Both bookmarks and publication entries can be tagged to help structure and re-find information. As the descriptive terms can be freely chosen, the assignment of tags from different users creates a spontaneous, uncontrolled vocabulary: a folksonomy. In BibSonomy, the folksonomy evolves from the participation of research groups, learning communities and individual users, organizing their information needs.
Publication posts in BibSonomy are stored in the BibTeX format. Export in other formats such as EndNote or HTML (e. g. for publication list creation) is possible. |
AFm phase | An AFm phase is an "alumina, ferric oxide, monosubstituted" phase, or aluminate ferrite monosubstituted, or Al2O3, Fe2O3 mono, in cement chemist notation (CCN). AFm phases are important hydration products in the hydration of Portland cements and hydraulic cements.
They are crystalline hydrates with generic, simplified, formula 3CaO·(Al,Fe)2O3·CaXy·nH2O, where: CaO, Al2O3, Fe2O3 represent calcium oxide, aluminium oxide, and ferric oxide, respectively; CaX represents a calcium salt, where X replaces an oxide ion; X is the substituted anion in CaX: – divalent (SO2−4, CO2−3…) with y = 1, or;– monovalent (OH−, Cl−…) with y = 2. |
Types of e-commerce | There are many types of e-commerce models', based on market segmentation, that can be used to conducted business online. The 6 types of business models that can be used in e-commerce include: Business-to-Consumer (B2C), Consumer-to-Business (C2B), Business-to-Business (B2B), Consumer-to-Consumer (C2C), Business-to-Administration (B2A), and Consumer-to-Administration |
Ponnuki | Ponnuki (ポン抜き, ponnuki, traditional Chinese: 開花; simplified Chinese: 开花; pinyin: kāi huā; Korean: 빵따냄 ppang-ttanaem or 빵때림 ppang-ttaerim; "open flower") is a Japanese term in the game of Go that refers to capturing a single stone, resulting in a diamond shape. The shape of the remaining capturing stones is considered to be very strong, due to its influence in all directions. A certain Go proverb says: "A Ponnuki is worth 30 points". |
Choledochal cysts | Choledochal cysts (a.k.a. bile duct cyst) are congenital conditions involving cystic dilatation of bile ducts. They are uncommon in western countries but not as rare in East Asian nations like Japan and China. |
ACIN1 | Apoptotic chromatin condensation inducer in the nucleus is a protein that in humans is encoded by the ACIN1 gene. |
Loxapine | Loxapine, sold under the brand names Loxitane and Adasuve (inhalation only) among others, is a tricyclic antipsychotic medication used primarily in the treatment of schizophrenia. The medicine is a member of the dibenzoxazepine class and structurally very similar to clozapine. Several researchers have argued that loxapine, initially classified as a typical antipsychotic, behaves as an atypical antipsychotic.Loxapine may be metabolized by N-demethylation to amoxapine, a tricyclic antidepressant. |
Hydrothermal circulation | Hydrothermal circulation in its most general sense is the circulation of hot water (Ancient Greek ὕδωρ, water, and θέρμη, heat ). Hydrothermal circulation occurs most often in the vicinity of sources of heat within the Earth's crust. In general, this occurs near volcanic activity, but can occur in the shallow to mid crust along deeply penetrating fault irregularities or in the deep crust related to the intrusion of granite, or as the result of orogeny or metamorphism. Hydrothermal circulation often results in hydrothermal mineral deposits. |
Rowing cycle | A rowing cycle is a wheeled vehicle propelled by a rowing motion of the body. Steering, braking, and shifting are usually done by the handlebars. Feet are on symmetrical foot rests, as opposed to rotating pedals. Unlike many rowing boats, the rider faces forward. Rowing cycles exist in numerous designs, particularly with respect to frames and drive mechanisms. Commercial production numbers for rowing cycles are small compared to that of standard bicycles. |
Conservation and restoration of vinyl discs | The conservation and restoration of vinyl discs refers to the preventive measures taken to defend against damage and slow degradation, and to maintain fidelity of singles, 12" singles, EP’s, and LP’s in 45 or 33⅓ rpm 10" disc recordings. Vinyl LP preservation is generally considered separate from conservation, which refers to the repair and stabilization of individual discs. Commonly practiced in major sound archives and research libraries that house large collections of audio recordings, it is also frequently followed by audiophiles and home record collectors. Because vinyl—a virtually unbreakable light plastic made up of polyvinyl chloride acetate copolymer, or PVC—is considered the most stable of analog recording media, it is seen as less a concern for deterioration than earlier sound recordings made from more fragile materials such as acetate, vulcanite, or shellac. This hardly means that vinyl recordings are infallible, however, and research—both expert and evidential—has shown that the way in which discs are handled and cared for can have a profound effect on their longevity. Though some 45s (7"s) are also made from vinyl, many of them are actually polystyrene—a more fragile medium that is prone to fracturing from internal stress. Still, many of the recommendations for the care of vinyl LPs can be applied to 45s. |
Fern sports | Fern sports are plants that show marked change from the normal type or parent stock as a result of mutation. The term Morphotype is also used for any of a group of different types of individuals of the same species in a population. Fern fronds in sports are typically altered in several ways, such as the frond apex divided and pinnae similarly duplicated. |
LeDock | LeDock is a proprietary flexible molecular docking software designed for the purpose of docking ligands with protein targets. It is available for Linux, macOS, and Windows.It can be ran as a standalone or entirely from Jupyter notebook. It only supports Tripos Mol2 file format. |
Field kitchen | A field kitchen (also known as a battlefield kitchen, expeditionary kitchen, flying kitchen, or goulash cannon) is a kitchen used primarily by militaries to provide hot food to troops near the front line or in temporary encampments. Designed to be easily and quickly moved, they are usually mobile kitchens or mobile canteens, though static and tent-based field kitchens exist and are widely used. |
Diborane(4) | Diborane(4) is a transient inorganic compound with the chemical formula B2H4. Stable derivatives are known. Diborane(4) has been produced by abstraction of two hydrogen atoms from diborane(6) using atomic fluorine and detected by photoionization mass spectrometry. Computational studies predict a structure in which are two hydrogen atoms bridging the two boron atoms via three-centre two-electron bonds in addition to the 2-centre, 2-electron bond between the two boron atoms and one terminal hydrogen atom bonded to each boron atom.Several stable derivatives of diborane(4) have been reported. |
Goodyear welt | A Goodyear welt is a strip of leather, rubber, or plastic that runs along the perimeter of a shoe outsole. The basic principle behind the Goodyear welt machine was invented in 1862 by August Destouy who designed a machine with a curved needle to stitch turned shoes. The machine was then improved in 1869 and later by Destouy and, more importantly, Daniel Mills, an English mechanic, both employed by Charles Goodyear Jr., the son of Charles Goodyear. It has been noted by historians that Goodyear was a frequent visitor to the shoe factory of William J. Dudley, founder of Johnston & Murphy, where early work on sole stitching equipment was performed. |
Autosomal dominant leukodystrophy with autonomic disease | Autosomal dominant leukodystrophy with autonomic disease is a rare neurological condition of genetic origin which is characterized by gradual demyelination of the central nervous system which results in various impairments, including ataxia, mild cognitive disability and autonomic dysfunction. It is part of a group of disorders called "leukodystrophies". |
History of virtual learning environments in the 1990s | In the history of virtual learning environments, the 1990s was a time of growth, primarily due to the advent of the affordable computer and of the Internet. |
Voiced pharyngeal fricative | The voiced pharyngeal approximant or fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʕ⟩, and the equivalent X-SAMPA symbol is ?\. Epiglottals and epiglotto-pharyngeals are often mistakenly taken to be pharyngeal.
Although traditionally placed in the fricative row of the IPA chart, [ʕ] is usually an approximant. The IPA symbol itself is ambiguous, but no language is known to make a phonemic distinction between fricatives and approximants at this place of articulation. The approximant is sometimes specified as [ʕ̞] or as [ɑ̯], because it is the semivocalic equivalent of [ɑ]. |
Translate (Apple) | Translate is a translation app developed by Apple for their iOS and iPadOS devices. Introduced on June 22, 2020, it functions as a service for translating text sentences or speech between several languages and was officially released on September 16, 2020, along with iOS 14. All translations are processed through the neural engine of the device, and as such can be used offline.On June 7, 2021, Apple announced that the app would be available on iPad models running iPadOS 15, as well as Macs running macOS Monterey. The app was officially released for iPad models on September 20, 2021, along with iPadOS 15. It was also released for Mac models on October 25, 2021, along with macOS Monterey. |
G-fibration | In algebraic topology, a G-fibration or principal fibration is a generalization of a principal G-bundle, just as a fibration is a generalization of a fiber bundle. By definition, given a topological monoid G, a G-fibration is a fibration p: P→B together with a continuous right monoid action P × G → P such that (1) p(xg)=p(x) for all x in P and g in G. |
Testin | Testin also known as TESS is a protein that in humans is encoded by the TES gene located on chromosome 7. TES is a 47 kDa protein composed of 421 amino acids found at focal adhesions and is thought to have a role in regulation of cell motility. In addition to this, TES functions as a tumour suppressor. The TES gene is located within a fragile region of chromosome 7, and the promoter elements of the TES gene have been shown to be susceptible to methylation – this prevents the expression of the TES protein. TES came to greater prominence towards the end of 2007 as a potential mechanism for its tumour suppressor function was published. |
Three-dimensional space | In geometry, a three-dimensional space (3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values (coordinates) are required to determine the position of a point. Most commonly, it is the three-dimensional Euclidean space, the Euclidean n-space of dimension n=3 that models physical space. More general three-dimensional spaces are called 3-manifolds.
Technically, a tuple of n numbers can be understood as the Cartesian coordinates of a location in a n-dimensional Euclidean space. The set of these n-tuples is commonly denoted Rn, and can be identified to the pair formed by a n-dimensional Euclidean space and a Cartesian coordinate system. |
Ester pyrolysis | Ester pyrolysis in organic chemistry is a vacuum pyrolysis reaction converting esters containing a β-hydrogen atom into the corresponding carboxylic acid and the alkene. The reaction is an Ei elimination and operates in a syn fashion.
Examples include the synthesis of acrylic acid from ethyl acrylate at 590 °C, the synthesis of 1,4-pentadiene from 1,5-pentanediol diacetate at 575 °C or the construction of a cyclobutene framework at 700 °C |
Sherwood Applied Business Security Architecture | SABSA (Sherwood Applied Business Security Architecture) is a model and methodology for developing a risk-driven enterprise information security architecture and service management, to support critical business processes. It was developed independently from the Zachman Framework, but has a similar structure. The primary characteristic of the SABSA model is that everything must be derived from an analysis of the business requirements for security, especially those in which security has an enabling function through which new business opportunities can be developed and exploited. |
Stage lighting accessories | Stage lighting accessories are components manufactured for conventional (non-automated) stage lighting instruments. Most conventional fixtures are designed to accept a number of different accessories designed to assist in the modification of the output. These accessories are intended to either provide relatively common functionality not originally provided in a fixture (such as beam shaping through barn doors), or to extend the versatility of a lighting instrument by introducing features. Other accessories have been designed to overcome limitations or difficulties some fixtures present in specific applications. |
Ammonium perrhenate | Ammonium perrhenate (APR) is the ammonium salt of perrhenic acid, NH4ReO4. It is the most common form in which rhenium is traded. It is a white salt; soluble in ethanol and water, and mildly soluble in NH4Cl. It was first described soon after the discovery of rhenium. |
Superconductor Science and Technology | Superconductor Science and Technology is a peer-reviewed scientific journal covering research on all aspects of superconductivity, including theories on superconductivity, the basic physics of superconductors, the relation of microstructure and growth to superconducting properties, the theory of novel devices, and the fabrication and properties of thin films and devices. The editor-in-chief is Cathy P Foley (CSIRO). It was established in 1988 and it is published by IOP Publishing. According to the Journal Citation Reports, the journal has an impact factor of 3.219 for 2020. |
CCT5 (gene) | T-complex protein 1 subunit epsilon is a protein that in humans is encoded by the CCT5 gene. |
Mucinous neoplasm | A mucinous neoplasm (also called colloid neoplasm) is an abnormal and excessive growth of tissue (neoplasia) with associated mucin (a fluid that sometimes resembles thyroid colloid). It arises from epithelial cells that line certain internal organs and skin, and produce mucin (the main component of mucus). A malignant mucinous neoplasm is called a mucinous carcinoma. For example, for ovarian mucinous tumors, approximately 75% are benign, 10% are borderline and 15% are malignant. |
Bond order | In chemistry, bond order is a formal measure of the multiplicity of a covalent bond between two atoms. As introduced by Linus Pauling, bond order is defined as the difference between the numbers of electron pairs in bonding and antibonding molecular orbitals.
Bond order gives a rough indication of the stability of a bond. Isoelectronic species have the same bond order. |
Ductility (Earth science) | In Earth science, ductility refers to the capacity of a rock to deform to large strains without macroscopic fracturing. Such behavior may occur in unlithified or poorly lithified sediments, in weak materials such as halite or at greater depths in all rock types where higher temperatures promote crystal plasticity and higher confining pressures suppress brittle fracture. In addition, when a material is behaving ductilely, it exhibits a linear stress vs strain relationship past the elastic limit.Ductile deformation is typically characterized by diffuse deformation (i.e. lacking a discrete fault plane) and on a stress-strain plot is accompanied by steady state sliding at failure, compared to the sharp stress drop observed in experiments during brittle failure. |
Non-relativistic spacetime | In physics, a non-relativistic spacetime is any mathematical model that fuses n–dimensional space and m–dimensional time into a single continuum other than the (3+1) model used in relativity theory.
In the sense used in this article, a spacetime is deemed "non-relativistic" if (a) it deviates from (3+1) dimensionality, even if the postulates of special or general relativity are otherwise satisfied, or if (b) it does not obey the postulates of special or general relativity, regardless of the model's dimensionality. |
Web User | Web User, branded as WebUser, was a fortnightly magazine published in the United Kingdom from 2001 until 2020. It covered topics relating to computing. Its sister magazine was ComputerActive. |

Spin gapless semiconductor | Spin gapless semiconductors are a novel class of materials with unique electrical band structure for different spin channels in such a way that there is no band gap (i.e., 'gapless') for one spin channel while there is a finite gap in another spin channel. |
CoRoT-18b | CoRoT-18b is a transiting Hot Jupiter exoplanet found by the CoRoT space telescope in 2011. |
Quantum dimer models | Quantum dimer models were introduced to model the physics of resonating valence bond (RVB) states in lattice spin systems. The only degrees of freedom retained from the motivating spin systems are the valence bonds, represented as dimers which live on the lattice bonds. In typical dimer models, the dimers do not overlap ("hardcore constraint").
Typical phases of quantum dimer models tend to be valence bond crystals. However, on non-bipartite lattices, RVB liquid phases possessing topological order and fractionalized spinons also appear. The discovery of topological order in quantum dimer models (more than a decade after the models were introduced) has led to new interest in these models.
Classical dimer models have been studied previously in statistical physics, in particular by P. W. Kasteleyn (1961) and M. E. Fisher (1961). |
Boomerang (cocktail) | A Boomerang cocktail is a specific cocktail dating back to the early 20th century. In the 21st century, it may also be a reference to cocktails that bartenders illegally shuttle back and forth between bars as a way of sharing experimentation or building comradery. |

Tcelna | Tcelna (formerly known as Tovaxin) is an anti-T cell vaccine being studied in multiple sclerosis (MS). As of 2016 it is in phase II trials. |
Constellation | A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object.The origins of the earliest constellations likely go back to prehistory. People used them to relate stories of their beliefs, experiences, creation, or mythology. Different cultures and countries invented their own constellations, some of which lasted into the early 20th century before today's constellations were internationally recognized. The recognition of constellations has changed significantly over time. Many changed in size or shape. Some became popular, only to drop into obscurity. Some were limited to a single culture or nation. Naming constellations also helped astronomers and navigators identify stars more easily.[1] Twelve (or thirteen) ancient constellations belong to the zodiac (straddling the ecliptic, which the Sun, Moon, and planets all traverse). The origins of the zodiac remain historically uncertain; its astrological divisions became prominent c. 400 BC in Babylonian or Chaldean astronomy. Constellations appear in Western culture via Greece and are mentioned in the works of Hesiodus, Eudoxus and Aratus. The traditional 48 constellations, consisting of the Zodiac and 36 more (now 38, following the division of Argo Navis into three constellations) are listed by Ptolemy, a Greco-Roman astronomer from Alexandria, Egypt, in his Almagest. The formation of constellations was the subject of extensive mythology, most notably in the Metamorphoses of the Latin poet Ovid. Constellations in the far southern sky were added from the 15th century until the mid-18th century when European explorers began traveling to the Southern Hemisphere. Due to Roman and European transmission, each constellation has a Latin name. |
Selfie stick | A selfie stick is used to take photographs or video by positioning a digital camera device, typically a smartphone, beyond the normal range of the arm. This allows for shots to be taken at angles and distances that would not have been possible with the human arm by itself. The sticks are typically extensible, with a handle on one end and an adjustable clamp on the other end to hold the device in place. As their name suggests, they are most commonly used for taking selfies with camera phones. |
Tissue paper | Tissue paper or simply tissue is a lightweight paper or, light crêpe paper. Tissue can be made from recycled paper pulp on a paper machine.
Tissue paper is very versatile, and different kinds of tissue are made to best serve these purposes, which are hygienic tissue paper, facial tissues, paper towels, as packing material, among other (sometimes creative) uses.
The use of tissue paper is common in developed nations, around 21 million tonnes in North America and 6 million in Europe, and is growing due to urbanization. As a result, the industry has often been scrutinized for deforestation. However, more companies are presently using more recycled fibres in tissue paper. |
Endoscopic ear surgery | Endoscopic ear surgery (EES) is a minimally invasive alternative to traditional ear surgery and is defined as the use of the rigid endoscope, as opposed to a surgical microscope, to visualize the middle and inner ear during otologic surgery. During endoscopic ear surgery the surgeon holds the endoscope in one hand while working in the ear with the other. To allow this kind of single-handed surgery, different surgical instruments have to be used. Endoscopic visualization has improved due to high-definition video imaging and wide-field endoscopy, and being less invasive, EES is gaining importance as an adjunct to microscopic ear surgery. |
Iodine compounds | Iodine can form compounds using multiple oxidation states. Iodine is quite reactive, but it is much less reactive than the other halogens. For example, while chlorine gas will halogenate carbon monoxide, nitric oxide, and sulfur dioxide (to phosgene, nitrosyl chloride, and sulfuryl chloride respectively), iodine will not do so. Furthermore, iodination of metals tends to result in lower oxidation states than chlorination or bromination; for example, rhenium metal reacts with chlorine to form rhenium hexachloride, but with bromine it forms only rhenium pentabromide and iodine can achieve only rhenium tetraiodide. By the same token, however, since iodine has the lowest ionisation energy among the halogens and is the most easily oxidised of them, it has a more significant cationic chemistry and its higher oxidation states are rather more stable than those of bromine and chlorine, for example in iodine heptafluoride. |
Latching switch | A latching switch is a switch that maintains its state after being activated. A push-to-make, push-to-break switch would therefore be a latching switch – each time you actuate it, whichever state the switch is left in will persist until the switch is actuated again. |
Tolylfluanid | Tolylfluanid is an organic chemical compound that is used as an active ingredient in fungicides and wood preservatives. |
Generalized erythema | Generalized erythema is a skin condition that may be caused by medications, bacterial toxins, or viral infections.: 139 |
Kite (geometry) | In Euclidean geometry, a kite is a quadrilateral with reflection symmetry across a diagonal. Because of this symmetry, a kite has two equal angles and two pairs of adjacent equal-length sides. Kites are also known as deltoids, but the word deltoid may also refer to a deltoid curve, an unrelated geometric object sometimes studied in connection with quadrilaterals. A kite may also be called a dart, particularly if it is not convex.Every kite is an orthodiagonal quadrilateral (its diagonals are at right angles) and, when convex, a tangential quadrilateral (its sides are tangent to an inscribed circle). The convex kites are exactly the quadrilaterals that are both orthodiagonal and tangential. They include as special cases the right kites, with two opposite right angles; the rhombi, with two diagonal axes of symmetry; and the squares, which are also special cases of both right kites and rhombi. |
SURF1 | Surfeit locus protein 1 (SURF1) is a protein that in humans is encoded by the SURF1 gene. The protein encoded by SURF1 is a component of the mitochondrial translation regulation assembly intermediate of cytochrome c oxidase complex (MITRAC complex), which is involved in the regulation of cytochrome c oxidase assembly. Defects in this gene are a cause of Leigh syndrome, a severe neurological disorder that is commonly associated with systemic cytochrome c oxidase (complex IV) deficiency, and Charcot-Marie-Tooth disease 4K (CMT4K). |
Mesoscale convective complex | A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. They are long-lived, often form nocturnally, and commonly contain heavy rainfall, wind, hail, lightning, and possibly tornadoes. |
Lookout | A lookout or look-out is a person in charge of the observation of hazards. The term originally comes from a naval background, where lookouts would watch for other ships, land, and various dangers. The term has now passed into wider parlance. |
Lignostilbene alphabeta-dioxygenase | In enzymology, a lignostilbene alphabeta-dioxygenase (EC 1.13.11.43) is an enzyme that catalyzes the chemical reaction 1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene + O2 ⇌ 2 vanillinThus, the two substrates of this enzyme are 1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene and O2, whereas its product is vanillin.
This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O2. The systematic name of this enzyme class is 1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene:oxygen oxidoreductase (alphabeta-bond-cleaving). It employs one cofactor, iron. |
Pilot error | Pilot error generally refers to an accident in which an action or decision made by the pilot was the cause or a contributing factor that led to the accident, but also includes the pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. The Chicago Convention defines the term "accident" as "an occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] except when the injuries are [...] inflicted by other persons." Hence the definition of "pilot error" does not include deliberate crashing (and such crashes are not classified as accidents). |
Rose Guns Days | Rose Guns Days (ローズガンズデイズ, Rōzu Ganzu Deizu) is a four-part Japanese dōjin visual novel series produced by 07th Expansion and playable on Windows PCs. The first game in the series, Season 1, was released on August 11, 2012, and the fourth game, Last Season, was released on December 31, 2013. There have been six manga adaptations based on Rose Guns Days published by Kodansha and Square Enix. |
Properties of water | Water (H2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound and is described as the "universal solvent" and the "solvent of life". It is the most abundant substance on the surface of Earth and the only common substance to exist as a solid, liquid, and gas on Earth's surface. It is also the third most abundant molecule in the universe (behind molecular hydrogen and carbon monoxide).Water molecules form hydrogen bonds with each other and are strongly polar. This polarity allows it to dissociate ions in salts and bond to other polar substances such as alcohols and acids, thus dissolving them. Its hydrogen bonding causes its many unique properties, such as having a solid form less dense than its liquid form, a relatively high boiling point of 100 °C for its molar mass, and a high heat capacity. |
Dual-use technology | In politics, diplomacy and export control, dual-use items refers to goods, software and technology that can be used for both civilian and military applications.More generally speaking, dual-use can also refer to any goods or technology which can satisfy more than one goal at any given time. Thus, expensive technologies that would otherwise benefit only civilian commercial interests can also be used to serve military purposes if they are not otherwise engaged, such as the Global Positioning System. |
Quantum secret sharing | Quantum secret sharing (QSS) is a quantum cryptographic scheme for secure communication that extends beyond simple quantum key distribution. It modifies the classical secret sharing (CSS) scheme by using quantum information and the no-cloning theorem to attain the ultimate security for communications.
The method of secret sharing consists of a sender who wishes to share a secret with a number of receiver parties in such a way that the secret is fully revealed only if a large enough portion of the receivers work together. However, if not enough receivers work together to reveal the secret, the secret remains completely unknown. |
Functor represented by a scheme | In algebraic geometry, a functor represented by a scheme X is a set-valued contravariant functor on the category of schemes such that the value of the functor at each scheme S is (up to natural bijections) the set of all morphisms S→X . The scheme X is then said to represent the functor and that classify geometric objects over S given by F.The best known example is the Hilbert scheme of a scheme X (over some fixed base scheme), which, when it exists, represents a functor sending a scheme S to a flat family of closed subschemes of X×S .In some applications, it may not be possible to find a scheme that represents a given functor. This led to the notion of a stack, which is not quite a functor but can still be treated as if it were a geometric space. (A Hilbert scheme is a scheme, but not a stack because, very roughly speaking, deformation theory is simpler for closed schemes.) Some moduli problems are solved by giving formal solutions (as opposed to polynomial algebraic solutions) and in that case, the resulting functor is represented by a formal scheme. Such a formal scheme is then said to be algebraizable if there is another scheme that can represent the same functor, up to some isomorphisms. |
Hexagonal architecture (software) | The hexagonal architecture, or ports and adapters architecture, is an architectural pattern used in software design. It aims at creating loosely coupled application components that can be easily connected to their software environment by means of ports and adapters. This makes components exchangeable at any level and facilitates test automation. |
Mystery of the Snow Pearls | Mystery of the Snow Pearls (ISBN 0-88038-196-5) is a 1985 adventure module for the Dungeons & Dragons roleplaying game. Its associated code is CM5 and the TSR product number is TSR 9154. |
Transgressive segregation | In genetics, transgressive segregation is the formation of extreme phenotypes, or transgressive phenotypes, observed in segregated hybrid populations compared to phenotypes observed in the parental lines. The appearance of these transgressive (extreme) phenotypes can be either positive or negative in terms of fitness. If both parents' favorable alleles come together, it will result in a hybrid having a higher fitness than the two parents. The hybrid species will show more genetic variation and variation in gene expression than their parents. As a result, the hybrid species will have some traits that are transgressive (extreme) in nature. Transgressive segregation can allow a hybrid species to populate different environments/niches in which the parent species do not reside, or compete in the existing environment with the parental species. |
Invincible error | Vincible ignorance is, in Catholic moral theology, ignorance that a person could remove by applying reasonable diligence in the given set of circumstances. It contrasts with invincible ignorance, which a person is either entirely incapable of removing, or could only do so by supererogatory efforts (i.e., efforts above and beyond normal duty).The first Pope to use the term invincible ignorance officially seems to have been Pope Pius IX in the allocution Singulari Quadam (9 December 1854) and the encyclicals Singulari Quidem (17 March 1856) and Quanto Conficiamur Moerore (10 August 1863). The term, however, is far older than that. Aquinas, for instance, uses it in his Summa Theologica (written 1265–1274), and discussion of the concept can be found as far back as Origen (3rd century). |
Total enclosure fetishism | Total enclosure fetishism is a form of sexual fetishism whereby a person becomes aroused when having entire body enclosed in a certain way. Total enclosure is often accompanied by some element of bondage. |
Tide | Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. |
PL-4 | PL-4 or POS-PHY Level 4 was the name of the interface that the interface SPI-4.2 is based on. It was proposed by PMC-Sierra to the Optical Internetworking Forum. The name means Packet Over SONET Physical layer level 4. PL-4 was developed by PMC-Sierra in conjunction with the Saturn Development Group. |
INO80B (gene) | INO80 complex subunit B is a protein that in humans is encoded by the INO80B gene. |
Prohead | A prohead or procapsid is an immature viral capsid structure formed in the early stages of self-assembly of some bacteriophages, including the Caudovirales or tailed bacteriophages. Production and assembly of stable proheads is an essential precursor to bacteriophage genome packaging; this packaging activity can be replicated in vitro. The prohead structure may take a different shape from the head of a mature virion, as seen with the prohead of Bacillus subtilis phage φ29. |
Fruit and vegetable wash | A vegetable wash is a cleaning product designed to aid in the removal process of dirt, wax and pesticides from fruit and vegetables before they are consumed. |
AM-087 | AM-087 (part of the AM cannabinoid series) is an analgesic drug which acts as a cannabinoid agonist. It is a derivative of Δ8-THC, substituted on the 3-position side chain. AM-087 is a potent CB1 agonist with a Ki of 0.43 nM, making it around 100 times more potent than THC itself. This is most likely due to the bulky bromine substituent on the side chain. |
Buffer (application) | Buffer is a software application for the web and mobile, designed to manage accounts in social networks, by providing the means for a user to schedule posts to Twitter, Facebook, Mastodon, Instagram, Instagram Stories, Pinterest, and LinkedIn, as well as analyze their results and engage with their community. It is owned by remote company Buffer Inc. |
