Linear complex structure | In mathematics, a complex structure on a real vector space V is an automorphism of V that squares to the minus identity, −I. Such a structure on V allows one to define multiplication by complex scalars in a canonical fashion so as to regard V as a complex vector space. |
Reflexive verb | In grammar, a reflexive verb is, loosely, a verb whose direct object is the same as its subject, for example, "I wash myself". More generally, a reflexive verb has the same semantic agent and patient (typically represented syntactically by the subject and the direct object). For example, the English verb to perjure is reflexive, since one can only perjure oneself. In a wider sense, the term refers to any verb form whose grammatical object is a reflexive pronoun, regardless of semantics; such verbs are also more broadly referred to as pronominal verbs, especially in the grammar of the Romance languages. Other kinds of pronominal verbs are reciprocal (they killed each other), passive (it is told), subjective, and idiomatic. The presence of the reflexive pronoun changes the meaning of a verb, e.g., Spanish abonar to pay, abonarse to subscribe.There are languages that have explicit morphology or syntax to transform a verb into a reflexive form. In many languages, reflexive constructions are rendered by transitive verbs followed by a reflexive pronoun, as in English -self (e.g., "She threw herself to the floor.") English employs reflexive derivation in idiosyncratically, as in "self-destruct". |
Boron triiodide | Boron triiodide is a chemical compound of boron and iodine with chemical formula BI3. It has a trigonal planar molecular geometry. It is a crystalline solid, which reacts vigorously with water to form hydroiodic acid and boric acid. Its dielectric constant is 5.38 and its heat of vaporization is 40.5 kJ/mol. At extremely high pressures, BI3 becomes metallic at ~23 GPa and is a superconductor above ~27 GPa. |
Cat train | A Cat train is a train of one or more supply sleds/sleighs hauled by a continuous track vehicle, and is typically used in roadless areas. They are so named for the caterpillar tracks of the hauling vehicle.
In northern climates, they were used to haul supplies to isolated communities in winter before engineers such as John Denison created modern winter roads which enabled standard winterized semi-trucks and trailers to haul these loads and heavier freight.
Cat trains are still used in areas where winter roads cannot be built, such as along the Hudson Bay, as seen in Season 9 of Ice Road Truckers. |
Economy car | Economy car is a term mostly used in the United States for cars designed for low-cost purchase and operation. Typical economy cars are small (compact or subcompact), lightweight, and inexpensive to both produce and purchase. Stringent design constraints generally force economy car manufacturers to be inventive. Many innovations in automobile design were originally developed for economy cars, such as the Ford Model T and the Austin Mini. |
UDP-glucose 6-dehydrogenase | UDP-glucose 6-dehydrogenase is a cytosolic enzyme that in humans is encoded by the UGDH gene.The protein encoded by this gene converts UDP-glucose to UDP-glucuronate and thereby participates in the biosynthesis of glycosaminoglycans such as hyaluronan, chondroitin sulfate, and heparan sulfate. These glycosylated compounds are common components of the extracellular matrix and likely play roles in signal transduction, cell migration, and cancer growth and metastasis. The expression of this gene is up-regulated by transforming growth factor beta and down-regulated by hypoxia.This enzyme participates in 4 metabolic pathways: pentose and glucuronate interconversions, ascorbate and aldarate metabolism, starch and sucrose metabolism, and nucleotide sugars metabolism. |
DOME MicroDataCenter | A microDataCenter contains compute, storage, power, cooling and networking in a very small volume, sometimes also called a "DataCenter-in-a-box". The term has been used to describe various incarnations of this idea over the past 20 years. Late 2017 a very tightly integrated version was shown at SuperComputing conference 2017: the DOME microDataCenter. Key features are its hot-watercooling, fully solid-state and being built with commodity components and standards only. |
Mixed martial arts in Australia | Mixed martial arts (MMA) has developed in Australia from a wide cross-section of sporting and martial arts disciplines to become the most popular combat sport in Australia. |
Nightmare flip | The nightmare flip (also known as a nightmare kickflip hyperflip or nightmare varial flip), is an aerial skateboarding trick. |
Macintosh Common Lisp | Macintosh Common Lisp (MCL) is an implementation and IDE for the Common Lisp programming language. Various versions of MCL run under the classic Mac OS (m68k and PPC) and Mac OS X.Versions of MCL up to and including 5.1 are proprietary. Version 5.2 has been open sourced.In 2009 a new different version of MCL has been open sourced: RMCL. RMCL is based on MCL 5.1 and does run under Rosetta on Intel-based Macs. |
Binomial proportion confidence interval | In statistics, a binomial proportion confidence interval is a confidence interval for the probability of success calculated from the outcome of a series of success–failure experiments (Bernoulli trials). In other words, a binomial proportion confidence interval is an interval estimate of a success probability p when only the number of experiments n and the number of successes nS are known. There are several formulas for a binomial confidence interval, but all of them rely on the assumption of a binomial distribution. In general, a binomial distribution applies when an experiment is repeated a fixed number of times, each trial of the experiment has two possible outcomes (success and failure), the probability of success is the same for each trial, and the trials are statistically independent. Because the binomial distribution is a discrete probability distribution (i.e., not continuous) and difficult to calculate for large numbers of trials, a variety of approximations are used to calculate this confidence interval, all with their own tradeoffs in accuracy and computational intensity. |
Switch hit | A switch hit is a modern cricket shot. A switch hit involves the batter effectively changing from a right-hander to a left-hander (or vice versa) just before the ball is delivered by the bowler for the purpose of executing the shot. It is a variation of the reverse sweep, in which the hands on the bat handle are switched and the stance is changed during the bowler's delivery action, and has been compared to switch-hitting in baseball. |
The Who's musical equipment | This is a history of the equipment that the English rock band The Who used. It also notes their influence on the instruments of the time period. |
Jargon | Jargon is the specialized terminology associated with a particular field or area of activity. Jargon is normally employed in a particular communicative context and may not be well understood outside that context. The context is usually a particular occupation (that is, a certain trade, profession, vernacular or academic field), but any ingroup can have jargon. The main trait that distinguishes jargon from the rest of a language is special vocabulary—including some words specific to it and often different senses or meanings of words, that outgroups would tend to take in another sense—therefore misunderstanding that communication attempt. Jargon is sometimes understood as a form of technical slang and then distinguished from the official terminology used in a particular field of activity.The terms jargon, slang, and argot are not consistently differentiated in the literature; different authors interpret these concepts in varying ways. According to one definition, jargon differs from slang in being secretive in nature; according to another understanding, it is specifically associated with professional and technical circles. Some sources, however, treat these terms as synonymous. In Russian linguistics, jargon is classified as an expressive form of language, while secret languages are referred to as argots. The use of jargon became more popular around the sixteenth century attracting persons from different career paths. This led to there being printed copies available on the various forms of jargon. |
Cold-shock domain | In molecular biology, the cold-shock domain (CSD) is a protein domain of about 70 amino acids which has been found in prokaryotic and eukaryotic DNA-binding proteins. Part of this domain is highly similar to the RNP-1 RNA-binding motif.When Escherichia coli is exposed to a temperature drop from 37 to 10 degrees Celsius, a 4–5 hour lag phase occurs, after which growth is resumed at a reduced rate. During the lag phase, the expression of around 13 proteins, which contain cold shock domains is increased 2–10 fold. These so-called cold shock proteins induced in the cold shock response are thought to help the cell to survive in temperatures lower than optimum growth temperature, by contrast with heat shock proteins induced in the heat shock response, which help the cell to survive in temperatures greater than the optimum, possibly by condensation of the chromosome and organisation of the prokaryotic nucleoid. |
Relationship obsessive–compulsive disorder | In psychology, relationship obsessive–compulsive disorder (ROCD) is a form of obsessive–compulsive disorder focusing on close or intimate relationships. Such obsessions can become extremely distressing and debilitating, having negative impacts on relationships functioning.Obsessive–compulsive disorder comprises thoughts, images or urges that are unwanted, distressing, interfere with a person's life and that are commonly experienced as contradicting a person's beliefs and values. Such intrusive thoughts are frequently followed by compulsive behaviors aimed at "neutralizing" the feared consequence of the intrusions and temporarily relieve the anxiety caused by the obsessions. Attempts to suppress or "neutralize" obsessions increase rather than decrease the frequency and distress caused by the obsessions. |
Hydrogen damage | Hydrogen damage is the generic name given to a large number of metal degradation processes due to interaction with hydrogen atoms. Note that molecular gaseous hydrogen does not have the same effect as atoms or ions released into solid solution in the metal. |
-yne | In chemistry, the suffix -yne is used to denote the presence of a triple bond.The suffix follows IUPAC nomenclature, and is mainly used in organic chemistry. However, inorganic compounds featuring unsaturation in the form of triple bonds may be denoted by substitutive nomenclature with the same methods used with alkynes, i.e., the name of the corresponding saturated hydride is modified by replacing the "-ane" ending with "-yne". The suffix "-diyne" is used when there are two triple bonds, and so on. The position of unsaturation is indicated by a numerical locant immediately preceding the "-yne" suffix, or locants in the case of multiple triple bonds. Locants are chosen to be as low as possible. While generally used as a suffix, "-yne" is also used as an infix to name substituent groups that are triply bound to the parent compound. |
Wet meadow | A wet meadow is a type of wetland with soils that are saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. |
David Rousseau | David Rousseau (born 1960) is a British systems philosopher, Director of the Centre for Systems Philosophy, chair of the Board of Trustees of the International Society for the Systems Sciences (ISSS), a Past President of the ISSS (2017-2018), and the Company Secretary of the British Association for the Study of Spirituality. He is known for having revived interest in establishing a scientific general systems theory (GST), for promoting systems philosophy as a route to advances in GST, for contributions on scientific general systems principles and for advocating systems research as a route to a scientific understanding of spiritual and other exceptional human experiences. His research interests include systems philosophy, systems science, systems engineering, systems methods for exploratory research, the mind-body problem, and the ontological foundations of moral intuitions. |
Cognitive response model | The cognitive response model of persuasion locates the most direct cause of persuasion in the self-talk of the persuasion target, rather than the content of the message. |
Tiling puzzle | Tiling puzzles are puzzles involving two-dimensional packing problems in which a number of flat shapes have to be assembled into a larger given shape without overlaps (and often without gaps). Some tiling puzzles ask you to dissect a given shape first and then rearrange the pieces into another shape. Other tiling puzzles ask you to dissect a given shape while fulfilling certain conditions. The two latter types of tiling puzzles are also called dissection puzzles. Tiling puzzles may be made from wood, metal, cardboard, plastic or any other sheet-material. Many tiling puzzles are now available as computer games. |
Rainbow Islands Evolution | Rainbow Islands Evolution is a game in the Bubble Bobble series for the PSP system. It is also known as New Rainbow Island: Hurdy Gurdy Daibōken!! (NEW(ニュー)レインボーアイランド ハーディガーディ大冒険!!, Nyū Reinbō Airando Hādi Gādi Daibōken!!) in Japan. It is an enhanced remake of the arcade game Rainbow Islands.
Bub and Bob, the two main characters in the series, are against an evil recording company that seeks to pollute the Rainbow Islands' atmosphere by creating constant musical noise, therefore wilting the flora and mutating the fauna. Bub and Bob use a hurdy-gurdy as a weapon to create the rainbows.
The game follows the same vertical-scrolling system from the original, but it expands to a third dimension as there are platforms in the background which become accessible through the course of the game. |
GDP-fucose protein O-fucosyltransferase 1 | GDP-fucose protein O-fucosyltransferase 1 also known as peptide-O-fucosyltransferase 1 (O-FucT-1) is an enzyme that in humans is encoded by the POFUT1 gene. |
Whittaker–Shannon interpolation formula | The Whittaker–Shannon interpolation formula or sinc interpolation is a method to construct a continuous-time bandlimited function from a sequence of real numbers. The formula dates back to the works of E. Borel in 1898, and E. T. Whittaker in 1915, and was cited from works of J. M. Whittaker in 1935, and in the formulation of the Nyquist–Shannon sampling theorem by Claude Shannon in 1949. It is also commonly called Shannon's interpolation formula and Whittaker's interpolation formula. E. T. Whittaker, who published it in 1915, called it the Cardinal series. |
Tacpac | TACPAC (derived from "tactile approach to communication package") is a sensory communication resource using touch and music to develop communication skills. It helps those who have sensory impairment or communication difficulties. It can also help those who have tactile defensiveness, learning difficulties, autism, Down syndrome, and dementia. |
Anaerobic membrane bioreactor | Anaerobic membrane bioreactor or AnMBR is the name of a technology utilized in wastewater treatment. It is a new technology in membrane filtration for biomass retention. AnMBR works by using a membrane bioreactor (MBR). The sewage is filtered and separated leaving the effluent and sludge apart. This sludge is treated anaerobically by mesophilic bacteria which release methane as a byproduct. The biogas can later be combusted to generate heat or electricity. AnMBR is considered to be a sustainable alternative for sewage treatment because the energy that can be generated by methane combustion can exceed the energy required for maintaining the process. |
Genome-wide association study | In genomics, a genome-wide association study (GWA study, or GWAS), is an observational study of a genome-wide set of genetic variants in different individuals to see if any variant is associated with a trait. GWA studies typically focus on associations between single-nucleotide polymorphisms (SNPs) and traits like major human diseases, but can equally be applied to any other genetic variants and any other organisms. |
Hybrid zone | A hybrid zone exists where the ranges of two interbreeding species or diverged intraspecific lineages meet and cross-fertilize. Hybrid zones can form in situ due to the evolution of a new lineage but generally they result from secondary contact of the parental forms after a period of geographic isolation, which allowed their differentiation (or speciation). Hybrid zones are useful in studying the genetics of speciation as they can provide natural examples of differentiation and (sometimes) gene flow between populations that are at some point between representing a single species and representing multiple species in reproductive isolation. |
Barnstorming (sports) | In athletics terminology, barnstorming refers to sports teams or individual athletes that travel to various locations, usually small towns, to stage exhibition matches. Barnstorming teams differ from traveling teams in that they operate outside the framework of an established athletic league, while traveling teams are designated by a league, formally or informally, to be a designated visiting team.Barnstorming allowed athletes to compete in two sports; for example, Goose Reece Tatum played basketball for the Harlem Globetrotters and baseball for a Negro leagues barnstorming team. Some barnstorming teams lack home arenas, while others go on "barnstorming tours" in the off-season. |
Dripstick | A dripstick is a thin hollow tube installed vertically in the bottoms of fuel tanks of many large aircraft, used to check fuel levels. To read a dripstick, it is withdrawn from the lower surface of the wing. When the top of the dripstick is withdrawn below the level of the fuel, fuel enters it and drips through a hole in the cap. Graduations on it indicate the level of fuel in the tank. |
Exploration of the Valley of the Amazon | Exploration of the Valley of the Amazon is a two-volume publication by two young USN lieutenants William Lewis Herndon (vol. 1) and Lardner A. Gibbon (vol. 2). Herndon split the main party in two so that he and Gibbon could explore two different areas of the Valley of the Amazon. |
Sugars in wine | Sugars in wine are at the heart of what makes winemaking possible. During the process of fermentation, sugars from wine grapes are broken down and converted by yeast into alcohol (ethanol) and carbon dioxide. Grapes accumulate sugars as they grow on the grapevine through the translocation of sucrose molecules that are produced by photosynthesis from the leaves. During ripening the sucrose molecules are hydrolyzed (separated) by the enzyme invertase into glucose and fructose. By the time of harvest, between 15 and 25% of the grape will be composed of simple sugars. Both glucose and fructose are six-carbon sugars but three-, four-, five- and seven-carbon sugars are also present in the grape. Not all sugars are fermentable, with sugars like the five-carbon arabinose, rhamnose and xylose still being present in the wine after fermentation. Very high sugar content will effectively kill the yeast once a certain (high) alcohol content is reached. For these reasons, no wine is ever fermented completely "dry" (meaning without any residual sugar). Sugar's role in dictating the final alcohol content of the wine (and such its resulting body and "mouth-feel") sometimes encourages winemakers to add sugar (usually sucrose) during winemaking in a process known as chaptalization solely in order to boost the alcohol content – chaptalization does not increase the sweetness of a wine. |
Canon EF 500mm lens | The EF 500mm lenses are a group of super-telephoto prime lenses made by Canon that share the same focal length.
These lenses have an EF type mount, and fit the Canon EOS line of digital single lens reflex cameras. |
Supersonic airfoils | A supersonic airfoil is a cross-section geometry designed to generate lift efficiently at supersonic speeds. The need for such a design arises when an aircraft is required to operate consistently in the supersonic flight regime. |
Reading stone | A reading stone is an approximately hemispherical lens that can be placed on top of text to magnify the letters so that people with presbyopia can read it more easily. Reading stones were among the earliest common uses of lenses. |
DNA polymerase alpha | DNA polymerase alpha also known as Pol α is an enzyme complex found in eukaryotes that is involved in initiation of DNA replication. The DNA polymerase alpha complex consists of 4 subunits: POLA1, POLA2, PRIM1, and PRIM2.Pol α has limited processivity and lacks 3′ exonuclease activity for proofreading errors. Thus it is not well suited to efficiently and accurately copy long templates (unlike Pol Delta and Epsilon). Instead it plays a more limited role in replication. Pol α is responsible for the initiation of DNA replication at origins of replication (on both the leading and lagging strands) and during synthesis of Okazaki fragments on the lagging strand. The Pol α complex (pol α-DNA primase complex) consists of four subunits: the catalytic subunit POLA1, the regulatory subunit POLA2, and the small and the large primase subunits PRIM1 and PRIM2 respectively. Once primase has created the RNA primer, Pol α starts replication elongating the primer with ~20 nucleotides. |
Phencyclidine | Phencyclidine or phenylcyclohexyl piperidine (PCP), also known as angel dust among other names, is a dissociative anesthetic mainly used recreationally for its significant mind-altering effects. PCP may cause hallucinations, distorted perceptions of sounds, and violent behavior. As a recreational drug, it is typically smoked, but may be taken by mouth, snorted, or injected. It may also be mixed with cannabis or tobacco.Adverse effects may include seizures, coma, addiction, and an increased risk of suicide. Flashbacks may occur despite stopping usage. Chemically, PCP is a member of the arylcyclohexylamine class, and pharmacologically, it is a dissociative anesthetic. PCP works primarily as an NMDA receptor antagonist.PCP is most commonly used in the United States. While usage peaked in the US in the 1970s, between 2005 and 2011 an increase in visits to emergency departments as a result of the drug occurred. As of 2017 in the United States, about 1% of people in 12th grade reported using PCP in the prior year while 2.9% of those over the age of 25 reported using it at some point in their lives. |
Nonconcatenative morphology | Nonconcatenative morphology, also called discontinuous morphology and introflection, is a form of word formation and inflection in which the root is modified and which does not involve stringing morphemes together sequentially. |
Journal of Micromechanics and Microengineering | The Journal of Micromechanics and Microengineering is a peer-reviewed scientific journal that covers all aspects of microelectromechanical systems, devices and structures, as well as micromechanics, microengineering, and microfabrication. The editor-in-chief is Weileun Fang (National Tsing Hua University). |
Hippocampal prosthesis | A hippocampus prosthesis is a type of cognitive prosthesis (a prosthesis implanted into the nervous system in order to improve or replace the function of damaged brain tissue). Prosthetic devices replace normal function of a damaged body part; this can be simply a structural replacement (e.g. reconstructive surgery or glass eye) or a rudimentary, functional replacement (e.g. a pegleg or hook). |
Minkowski's first inequality for convex bodies | In mathematics, Minkowski's first inequality for convex bodies is a geometrical result due to the German mathematician Hermann Minkowski. The inequality is closely related to the Brunn–Minkowski inequality and the isoperimetric inequality. |
Indian Journal of Dermatology | The Indian Journal of Dermatology is a bimonthly peer-reviewed open-access medical journal published on behalf of the Indian Association of Dermatologists, Venereologists and Leprologists, West Bengal Branch. The journal covers clinical and experimental dermatology, cutaneous biology, dermatological therapeutics, cosmetic dermatology, dermatopathology, and dermatosurgery.It was established in 1955. |
Spermidine dehydrogenase | In enzymology, a spermidine dehydrogenase (EC 1.5.99.6) is an enzyme that catalyzes the chemical reaction spermidine + acceptor + H2O ⇌ propane-1,3-diamine + 4-aminobutanal + reduced acceptorThe 3 substrates of this enzyme are spermidine, acceptor, and H2O, whereas its 3 products are propane-1,3-diamine, 4-aminobutanal, and reduced acceptor.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donor with other acceptors. The systematic name of this enzyme class is spermidine:acceptor oxidoreductase. This enzyme is also called spermidine:(acceptor) oxidoreductase. This enzyme participates in urea cycle and metabolism of amino groups and beta-alanine metabolism. It has 2 cofactors: FAD, and Heme. |
Structural acoustics | Structural acoustics is the study of the mechanical waves in structures and how they interact with and radiate into adjacent media. The field of structural acoustics is often referred to as vibroacoustics in Europe and Asia. People that work in the field of structural acoustics are known as structural acousticians. The field of structural acoustics can be closely related to a number of other fields of acoustics including noise, transduction, underwater acoustics, and physical acoustics. |
PDF Expert | PDF Expert is a PDF editing app for iPhone, iPad and Mac. |
Trip valve gear | Trip valve mechanisms are a class of steam engine valve gear developed to improve efficiency. The trip mechanism allows the inlet valve to be closed rapidly, giving a short, sharp cut-off. The valve itself can be a drop valve or a Corliss valve. |
Piste (fencing) | In modern fencing, the piste or strip is the playing area. Regulations require the piste to be 14 metres long and 1.5 metres wide. The last two metres on each end are hash-marked to warn a fencer before they back off the end of the strip, after which is a 1.5 to 2 metre runoff. The piste is also marked at the centre and at the "en garde" lines, located two metres either side of the center line. |
BeOS R5.1d0 | BeOS R5.1d0 or Dano/EXP (also known as EXP, Dano, and incorrectly as Dan0/EXP or Dan0) is the build codename and most commonly used name to refer to a leaked R5.1 prerelease of the Be Operating System. Dano's build date is 15 November 2001, the day of Be Inc.'s closure. Dano features an improved network stack called BONE, initial support for 802.11b wireless networking, some 3D acceleration-capable graphics drivers, a redesigned graphical user interface, a replacement USB subsystem with USB mass storage support, and other improvements. Many of these features had been promised for BeOS R5 a year earlier and not delivered. |
Antisense RNA | Antisense RNA (asRNA), also referred to as antisense transcript, natural antisense transcript (NAT) or antisense oligonucleotide, is a single stranded RNA that is complementary to a protein coding messenger RNA (mRNA) with which it hybridizes, and thereby blocks its translation into protein. The asRNAs (which occur naturally) have been found in both prokaryotes and eukaryotes, and can be classified into short (<200 nucleotides) and long (>200 nucleotides) non-coding RNAs (ncRNAs). The primary function of asRNA is regulating gene expression. asRNAs may also be produced synthetically and have found wide spread use as research tools for gene knockdown. They may also have therapeutic applications. |
Paul K. Chu | Paul K. Chu (朱劍豪) is a specialist in plasma surface modification and materials science. He is Chair Professor of Materials Engineering in the Department of Physics, Department of Materials Science & Engineering, and Department of Biomedical Engineering at City University of Hong Kong. |
Stained Glass (puzzle) | Stained Glass is a binary determination logic puzzle published by Nikoli. |
Sturtian glaciation | The Sturtian glaciation was a worldwide glaciation during the Cryogenian Period when the Earth experienced repeated large-scale glaciations. As of January 2023, the Sturtian glaciation is thought to have lasted from c. 717 Ma to c. 660 Ma, a time span of approximately 57 million years. It is hypothesised to have been be a Snowball Earth event, or contrastingly multiple regional glaciations, and is the longest and most severe known glacial event preserved in the geologic record. |
Dislocation avalanches | Dislocation avalanches are rapid discrete events during plastic deformation, in which defects are reorganized collectively. This intermittent flow behavior has been observed in microcrystals, whereas macroscopic plasticity appears as a smooth process. Intermittent plastic flow has been observed in several different systems. In AlMg Alloys, interaction between solute and dislocations can cause sudden jump during dynamic strain aging. In metallic glass, it can be observed via shear banding with stress localization; and single crystal plasticity, it shows up as slip burst. However, analysis of the events with orders-magnitude difference in sizes with different crystallographic structure reveals power-law scaling between the number of events and their magnitude, or scale-free flow.This microscopic instability of plasticity can have profound consequences on mechanical behavior of microcrystals. The increased relative size of the fluctuations makes it difficult to control the plastic forming process. Moreover, at small specimen sizes the yield stress is not well defined by the 0.2% plastic strain criterion anymore, since this value varies specimen by specimen.Similar intermittent effects has been studied in many completely different systems, including intermittency of energy dissipation in magnetism (Barkhausen effect), superconductivity, earthquakes, and friction. |
Multimodal therapy | Multimodal therapy (MMT) is an approach to psychotherapy devised by psychologist Arnold Lazarus, who originated the term behavior therapy in psychotherapy. It is based on the idea that humans are biological beings that think, feel, act, sense, imagine, and interact—and that psychological treatment should address each of these modalities. Multimodal assessment and treatment follows seven reciprocally influential dimensions of personality (or modalities) known by their acronym BASIC I.D.: behavior, affect, sensation, imagery, cognition, interpersonal relationships, and drugs/biology. |
Recurrent point | In mathematics, a recurrent point for a function f is a point that is in its own limit set by f. Any neighborhood containing the recurrent point will also contain (a countable number of) iterates of it as well. |
Now You See It (American game show) | Now You See It is an American television game show created by Frank Wayne for Mark Goodson-Bill Todman Productions. The object of Now You See It is to answer general knowledge trivia questions by finding the answers hidden in a grid, similar to a word search puzzle. |
Comma splice | In written English usage, a comma splice or comma fault is the use of a comma to join two independent clauses. For example: It is nearly half past five, we cannot reach town before dark.
The comma splice is sometimes used in literary writing to convey a particular mood of informality. In the United States it is usually considered an error in English writing style. Some authorities on English usage consider comma splices appropriate in limited situations, such as informal writing or with short similar phrases. |
L-methionine (S)-S-oxide reductase | In enzymology, a L-methionine (S)-S-oxide reductase (EC 1.8.4.13) is an enzyme that catalyzes the chemical reaction L-methionine + thioredoxin disulfide + H2O ⇌ L-methionine (S)-S-oxide + thioredoxinThe 3 substrates of this enzyme are L-methionine, thioredoxin disulfide, and H2O, whereas its two products are L-methionine (S)-S-oxide and thioredoxin. |
Gene redundancy | Gene redundancy is the existence of multiple genes in the genome of an organism that perform the same function. Gene redundancy can result from gene duplication. Such duplication events are responsible for many sets of paralogous genes. When an individual gene in such a set is disrupted by mutation or targeted knockout, there can be little effect on phenotype as a result of gene redundancy, whereas the effect is large for the knockout of a gene with only one copy. Gene knockout is a method utilized in some studies aiming to characterize the maintenance and fitness effects functional overlap. |
Gasoline gallon equivalent | Gasoline gallon equivalent (GGE) or gasoline-equivalent gallon (GEG) is the amount of an alternative fuel it takes to equal the energy content of one liquid gallon of gasoline. GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel, namely gasoline. |
GB-PVR | GB-PVR was a PVR (personal video recorder aka digital video recorder) application, running on Microsoft Windows, whose main function was scheduling TV recordings and playing back live TV. GB-PVR is no longer under active development and has been superseded by NextPVR, also known as nPVR.GB-PVR also acts as a home media center software with a digital video recorder, a radio station online tuner, a music and movie player, a library of images and other features. |
Clean and press | The clean and press is a two-part weight training exercise whereby a loaded barbell is lifted from the floor to the shoulders (the clean) and pushed overhead (the press). The lift was a component of the sport of Olympic weightlifting from 1928 to 1972, but was removed due to difficulties in judging proper technique. |
Toy train | A toy train is a toy that represents a train. It is distinguished from a model train by an emphasis on low cost and durability, rather than scale modeling. A toy train can be as simple as a toy that can run on a track, or it might be operated by electricity, clockwork or live steam. It is typically constructed from wood, plastic or metal. Many of today's steam trains might be considered as real ones as well, providing they are not strictly scale or not enough detailed ones in favor of a robustness appropriate for children or an inexpensive production. |
Bateman transform | In the mathematical study of partial differential equations, the Bateman transform is a method for solving the Laplace equation in four dimensions and wave equation in three by using a line integral of a holomorphic function in three complex variables. It is named after the English mathematician Harry Bateman, who first published the result in (Bateman 1904).
The formula asserts that if ƒ is a holomorphic function of three complex variables, then ϕ(w,x,y,z)=∮γf((w+ix)+(iy+z)ζ,(iy−z)+(w−ix)ζ,ζ)dζ is a solution of the Laplace equation, which follows by differentiation under the integral. Furthermore, Bateman asserted that the most general solution of the Laplace equation arises in this way. |
Solar eclipse of August 1, 1943 | An annular solar eclipse occurred on Sunday, August 1, 1943. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. |
Gallbladder | In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. In humans, the pear-shaped gallbladder lies beneath the liver, although the structure and position of the gallbladder can vary significantly among animal species. It receives and stores bile, produced by the liver, via the common hepatic duct, and releases it via the common bile duct into the duodenum, where the bile helps in the digestion of fats. |
Escutcheon (furniture) | An escutcheon ( ih-SKUTCH-ən) is a general term for a decorative plate used to conceal a functioning, non-architectural item. Escutcheon is an Old Norman word derived from the Latin word scutum, meaning a shield. Escutcheons are most often used in conjunction with mechanical, electrical, and plumbing components and fixtures where a pipe, tube, or conduit passes through a wall [or other material] surface. The escutcheon is used to bridge the gap between the outside diameter of the pipe and the inside diameter of the opening in said surface. |
Mathematics (journal) | Mathematics is a semi-monthly peer-reviewed open-access scientific journal that covers all aspects of mathematics. It publishes theoretical and experimental research articles, short communications, and reviews. It was established in 2013 and is published by MDPI. The editor-in-chief is Francisco Chiclana (De Montfort University). |
Well-known text representation of geometry | Well-known text (WKT) is a text markup language for representing vector geometry objects. A binary equivalent, known as well-known binary (WKB), is used to transfer and store the same information in a more compact form convenient for computer processing but that is not human-readable. The formats were originally defined by the Open Geospatial Consortium (OGC) and described in their Simple Feature Access. The current standard definition is in the ISO/IEC 13249-3:2016 standard. |
Muddler | A muddler is a bartender's tool, used like a pestle to mash—or muddle—fruits, herbs and spices in the bottom of a glass to release their flavor. |
Bitruncation | In geometry, a bitruncation is an operation on regular polytopes. It represents a truncation beyond rectification. The original edges are lost completely and the original faces remain as smaller copies of themselves.
Bitruncated regular polytopes can be represented by an extended Schläfli symbol notation t1,2{p,q,...} or 2t{p,q,...}. |
78K | 78K is the trademark name of 16- and 8-bit microcontroller family: 23-4–23-5 : 78 manufactured by Renesas Electronics, originally developed by NEC: 229 started in 1986.: 7, line 2 The basis of 78K Family is an accumulator-based register-bank CISC architecture. |
Picardy third | A Picardy third, (; French: tierce picarde) also known as a Picardy cadence or Tierce de Picardie, is a major chord of the tonic at the end of a musical section that is either modal or in a minor key. This is achieved by raising the third of the expected minor triad by a semitone to create a major triad, as a form of resolution.For example, instead of a cadence ending on an A minor chord containing the notes A, C, and E, a Picardy third ending would consist of an A major chord containing the notes A, C♯, and E. The minor third between the A and C of the A minor chord has become a major third in the Picardy third chord. |
Non-ferrous extractive metallurgy | Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. Metals like zinc, copper, lead, aluminium as well as rare and noble metals are of particular interest in this field, while the more common metal, iron, is considered a major impurity. Like ferrous extraction, non-ferrous extraction primarily focuses on the economic optimization of extraction processes in separating qualitatively and quantitatively marketable metals from its impurities (gangue).Any extraction process will include a sequence of steps or unit processes for separating highly pure metals from undesirables in an economically efficient system. Unit processes are usually broken down into three categories: pyrometallurgy, hydrometallurgy, and electrometallurgy. In pyrometallurgy, the metal ore is first oxidized through roasting or smelting. The target metal is further refined at high temperatures and reduced to its pure form. In hydrometallurgy, the object metal is first dissociated from other materials using a chemical reaction, which is then extracted in pure form using electrolysis or precipitation. Finally, electrometallurgy generally involves electrolytic or electrothermal processing. The metal ore is either distilled in an electrolyte or acid solution, then magnetically deposited onto a cathode plate (electrowinning); or smelted then melted using an electric arc or plasma arc furnace (electrothermic reactor).Another major difference in non-ferrous extraction is the greater emphasis on minimizing metal losses in slag. This is widely due to the exceptional scarcity and economic value of certain non-ferrous metals which are, inevitably, discarded during the extraction process to some extent. Thus, material resource scarcity and shortages are of great concern to the non-ferrous industry. Recent developments in non-ferrous extractive metallurgy now emphasize the reprocessing and recycling of rare and non-ferrous metals from secondary raw materials (scrap) found in landfills. |
Poly(methyl acrylate) | Poly(methyl acrylate) (PMA) is a family of organic polymers with the formula (CH2CHCO2CH3)n. It is a synthetic acrylate polymer derived from methyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from methyl acrylate and other monomers. PMA is softer than polymethyl methacrylate (PMMA), It is tough, leathery, and flexible. |
Kodaira surface | In mathematics, a Kodaira surface is a compact complex surface of Kodaira dimension 0 and odd first Betti number. The concept is named after Kunihiko Kodaira. |
Palinopsia | Palinopsia (Greek: palin for "again" and opsia for "seeing") is the persistent recurrence of a visual image after the stimulus has been removed. Palinopsia is not a diagnosis; it is a diverse group of pathological visual symptoms with a wide variety of causes. Visual perseveration is synonymous with palinopsia.In 2014, Gersztenkorn and Lee comprehensively reviewed all cases of palinopsia in the literature and subdivided it into two clinically relevant groups: illusory palinopsia and hallucinatory palinopsia. Hallucinatory palinopsia, usually due to seizures or posterior cortical lesions, describes afterimages that are formed, long-lasting, and high resolution. Illusory palinopsia, usually due to migraines, head trauma, prescription drugs, visual snow or hallucinogen persisting perception disorder (HPPD), describes afterimages that are affected by ambient light and motion and are unformed, indistinct, or low resolution. |
Cannabis in Romania | Cannabis in Romania is illegal for recreational and for medical use. Although it was technically legalized for medical use in 2013, it has not been eliminated from the Table I of High Risk Drugs, and as such its use is prohibited. Some of the earliest evidence of the psychoactive use of cannabis have been found in Romania, including the archaeological sites of Frumușica and Gurbănești. |
Open Access Network | The Open Access Network (OAN) encourages partnerships between scholarly societies, research libraries, and other institutional partners in order to support the infrastructure of scholarly communication and support open access publishing in the humanities and social sciences.

It runs on top of either OpenGL or Direct3D until version 1.6.0, which runs on top of Java OpenGL (JOGL). Since version 1.2, Java 3D has been developed under the Java Community Process. A Java 3D scene graph is a directed acyclic graph (DAG). |
Tubomanometry | Tubomanometry is a technique for assessing the eustachian tube opening function, and sometimes to determine a treatment plan. This technique was familiarised by D. Estève et al in 2001. |
Tetrapeptide | A tetrapeptide is a peptide, classified as an oligopeptide, since it only consists of four amino acids joined by peptide bonds. Many tetrapeptides are pharmacologically active, often showing affinity and specificity for a variety of receptors in protein-protein signaling. Present in nature are both linear and cyclic tetrapeptides (CTPs), the latter of which mimics protein reverse turns which are often present on the surface of proteins and druggable targets. Tetrapeptides may be cyclized by a fourth peptide bond or other covalent bonds. |
Academic Technology Approval Scheme | The Academic Technology Approval Scheme (ATAS) is a scheme of the British government for certifying foreign students from outside the EU for entry into the United Kingdom to study or conduct research in certain sensitive technology-related fields. For these students, obtaining an ATAS certificate is a prerequisite for obtaining a visa. The ATAS was introduced on 1 November 2007 to prevent dissemination outside the UK of knowledge and skills that can be used to build and deliver weapons of mass destruction (WMD), by ensuring that applicants do not have links to Advanced Conventional Military Technology (ACMT), WMD programmes and their means of delivery.Affected students undergo a screening system to validate their reasons for coming to the UK. |

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acyl-CoA:1-O-alkyl-2-acetyl-sn-glycerol O-acyltransferase. This enzyme is also called 1-hexadecyl-2-acetylglycerol acyltransferase. This enzyme participates in ether lipid metabolism. |
Buzz cut | A buzz cut, or wiffle cut, is a variety of short hairstyles, especially where the length of hair is the same on all parts of the head. Rising to prominence initially with the advent of manual hair clippers, buzz cuts became increasingly popular in places where strict grooming conventions applied. In several nations, buzz cuts are often given to new recruits in the armed forces. However, buzz cuts are also used for stylistic reasons. |
Synaptojanin | Synaptojanin is a protein involved in vesicle uncoating in neurons. This is an important regulatory lipid phosphatase. It dephosphorylates the D-5 position phosphate from phosphatidylinositol (3,4,5)-trisphosphate (PIP3) and Phosphatidylinositol (4,5)-bisphosphate(PIP2). It belongs to family of 5-phosphatases, which are structurally unrelated to D-3 inositol phosphatases like PTEN. Other members of the family of 5'phosphoinositide phosphatases include OCRL, SHIP1, SHIP2, INPP5J, INPP5E, INPP5B, INPP5A and SKIP. |
Fashion merchandising | Fashion merchandising can be defined as the planning and promotion of sales by presenting a product to the right market at the proper time, by carrying out organized, skillful advertising, using attractive displays, etc. Merchandising, within fashion retail, refers specifically to the stock planning, management, and control process. Fashion Merchandising is a job that is done world- wide. This position requires well-developed quantitative skills, and natural ability to discover trends, meaning relationships and interrelationships among standard sales and stock figures. In the fashion industry, there are two different merchandising teams: the visual merchandising team, and the fashion merchandising team. |
Island single malt | Island single malts are the single malt Scotch whiskies produced on the islands around the perimeter of the Scottish mainland. The islands (excluding Islay) are not recognised in the Scotch Whisky Regulations as a distinct whisky producing region, but are considered to be part of the Highland region. Islay is itself recognised as a distinct whisky producing region (see Islay whisky). |
Heavy equipment | Heavy Equipment, Heavy Machinery, Earthmovers, Construction Vehicles, or Construction Equipment, refers to heavy-duty vehicles specially designed to execute construction tasks, most frequently involving earthwork operations or other large construction tasks. Heavy equipment usually comprises five equipment systems: the implement, traction, structure, power train, and control/information. Heavy equipment has been used since at least the 1st century BC when the ancient Roman engineer Vitruvius described a crane in De architectura when it was powered via human or animal labor. |
Collapse | Collapse or its variants may refer to: |
Groundcover | Groundcover or ground cover is any plant that grows over an area of ground. Groundcover provides protection of the topsoil from erosion and drought.
In an ecosystem, the ground cover forms the layer of vegetation below the shrub layer known as the herbaceous layer. The most widespread ground covers are grasses of various types. |
FBXO7 | F-box only protein 7 is a protein that in humans is encoded by the FBXO7 gene. Mutations in FBXO7 have been associated with Parkinson's disease. |
Beat (filmmaking) | In filmmaking, a beat is a small amount of action resulting in a pause in dialogue. Beats usually involve physical gestures like a character walking to a window or removing their glasses and rubbing their eyes. Short passages of internal monologue can also be considered a sort of internal beat. Beats are also known as "stage business".The word "beat" is industry slang that was derived from a famous Russian writer who told someone that writing the script was just a matter of putting all the bits together. In his heavy accent he pronounced bits as "beats".A beat sheet is a document with all the events in a movie script to guide the writing of that script. |
Kickboxing weight classes | Kickboxing weight classes are weight classes that pertain to the sport of kickboxing. |
Basket weaving | Basket weaving (also basketry or basket making) is the process of weaving or sewing pliable materials into three-dimensional artifacts, such as baskets, mats, mesh bags or even furniture. Craftspeople and artists specialized in making baskets may be known as basket makers and basket weavers. Basket weaving is also a rural craft.
Basketry is made from a variety of fibrous or pliable materials—anything that will bend and form a shape. Examples include pine, straw, willow, oak, wisteria, forsythia, vines, stems, fur, hide, grasses, thread, and fine wooden splints. There are many applications for basketry, from simple mats to hot air balloon gondolas.
Many Indigenous peoples are renowned for their basket-weaving techniques. |
Helix (ear) | The helix is the prominent rim of the auricle. Where the helix turns downwards posteriorly, a small tubercle is sometimes seen, namely the auricular tubercle of Darwin. |
Corneal ectatic disorders | Corneal ectatic disorders or corneal ectasia are a group of uncommon, noninflammatory, eye disorders characterised by bilateral thinning of the central, paracentral, or peripheral cornea. |
Ball screw | A ball screw (or ballscrew) is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary. The ball assembly acts as the nut while the threaded shaft is the screw. |
