Canadian Family Physician | Canadian Family Physician (French: Le Médecin de famille canadien) is a monthly peer-reviewed open-access medical journal published by the College of Family Physicians of Canada. It provides continuing medical education for family physicians and other primary care clinicians. The journal publishes original articles presenting a family medicine perspective to clinical medicine through approaches to common clinical conditions and evidence-based clinical reviews intended to assist family physicians in patient care. Most articles are published in both English and French. The journal was established in 1967 and the editor-in-chief is Nicholas Pimlott (University of Toronto). |
Clinic (music) | A musical clinic is an informal meeting with a guest musician, where a small-to-medium-sized audience questions the musician's styles and techniques and also how to improve their own skill. The musician might perform an entire piece, or demonstrate certain techniques for the audience to observe. The objective is for the audience to learn from the guest musician. A musical clinic can apply to any type of musical instrument, music or player. The clinics are often held at musical instrument stores. |
Aeromagnetic survey | An aeromagnetic survey is a common type of geophysical survey carried out using a magnetometer aboard or towed behind an aircraft. The principle is similar to a magnetic survey carried out with a hand-held magnetometer, but allows much larger areas of the Earth's surface to be covered quickly for regional reconnaissance. The aircraft typically flies in a grid-like pattern with height and line spacing determining the resolution of the data (and cost of the survey per unit area). |
Molybdenum disilicide | Molybdenum disilicide (MoSi2, or molybdenum silicide), an intermetallic compound, a silicide of molybdenum, is a refractory ceramic with primary use in heating elements. It has moderate density, melting point 2030 °C, and is electrically conductive. At high temperatures it forms a passivation layer of silicon dioxide, protecting it from further oxidation. The thermal stability of MoSi2 alongside its high emissivity make this material, alongside WSi2 attractive for applications as a high emissivity coatings in heat shields for atmospheric entry. MoSi2 is a gray metallic-looking material with tetragonal crystal structure (alpha-modification); its beta-modification is hexagonal and unstable. It is insoluble in most acids but soluble in nitric acid and hydrofluoric acid. |
Rational Rhapsody | Rational Rhapsody, a modeling environment based on UML, is a visual development environment for systems engineers and software developers creating real-time or embedded systems and software. Rational Rhapsody uses graphical models to generate software applications in various languages including C, C++, Ada, Java and C#. |
Persistent current | In physics, persistent current refers to a perpetual electric current, not requiring an external power source. Such a current is impossible in normal electrical devices, since all commonly-used conductors have a non-zero resistance, and this resistance would rapidly dissipate any such current as heat. However, in superconductors and some mesoscopic devices, persistent currents are possible and observed due to quantum effects. In resistive materials, persistent currents can appear in microscopic samples due to size effects. Persistent currents are widely used in the form of superconducting magnets. |
Ornithodoros | Ornithodoros is a genus in the soft-bodied tick family, Argasidae. |
Mutton flaps | Mutton flaps, or breast of lamb, are an inexpensive cut of meat from a sheep. |
Flogo | A Flogo (portmanteau of floating and logo) or foam balloon, is a stable mass of lighter-than-air soap bubbles formed into a specific shape. They are not balloons, as they have no envelope, but consist merely of a condensed grouping of soap bubbles filled with a mixture of helium and air. They are shaped by being molded through a die inserted in the top of the generating machine. |
Dirichlet boundary condition | In the mathematical study of differential equations, the Dirichlet (or first-type) boundary condition is a type of boundary condition, named after Peter Gustav Lejeune Dirichlet (1805–1859). When imposed on an ordinary or a partial differential equation, it specifies the values that a solution needs to take along the boundary of the domain. |
Automatic clustering algorithms | Automatic clustering algorithms are algorithms that can perform clustering without prior knowledge of data sets. In contrast with other cluster analysis techniques, automatic clustering algorithms can determine the optimal number of clusters even in the presence of noise and outlier points. |
Worldly cardinal | In mathematical set theory, a worldly cardinal is a cardinal κ such that the rank Vκ is a model of Zermelo–Fraenkel set theory. |
Singular homology | In algebraic topology, singular homology refers to the study of a certain set of algebraic invariants of a topological space X, the so-called homology groups Hn(X). |
Kramers' theorem | In quantum mechanics, the Kramers' degeneracy theorem states that for every energy eigenstate of a time-reversal symmetric system with half-integer total spin, there is another eigenstate with the same energy related by time-reversal. In other words, the degeneracy of every energy level is an even number if it has half-integer spin. The theorem is named after Dutch physicist H. A. Kramers. |
Special use airspace | Special use airspace (SUA) is an area designated for operations of a nature such that limitations may be imposed on aircraft not participating in those operations. Often these operations are of a military nature. The designation of SUAs identifies for other users the areas where such activity occurs, provides for segregation of that activity from other users, and allows charting to keep airspace users informed of potential hazards. Most SUAs are depicted on aeronautical charts and FAA maintains a page showing the current status of most SUAs. |
Iodine-123 | Iodine-123 (123I) is a radioactive isotope of iodine used in nuclear medicine imaging, including single-photon emission computed tomography (SPECT) or SPECT/CT exams. The isotope's half-life is 13.2230 hours; the decay by electron capture to tellurium-123 emits gamma radiation with a predominant energy of 159 keV (this is the gamma primarily used for imaging). In medical applications, the radiation is detected by a gamma camera. The isotope is typically applied as iodide-123, the anionic form. |
Hygroscopy | Hygroscopy is the phenomenon of attracting and holding water molecules via either absorption or adsorption from the surrounding environment, which is usually at normal or room temperature. If water molecules become suspended among the substance's molecules, adsorbing substances can become physically changed, e.g., changing in volume, boiling point, viscosity or some other physical characteristic or property of the substance. For example, a finely dispersed hygroscopic powder, such as a salt, may become clumpy over time due to collection of moisture from the surrounding environment. |
Interruption (speech) | An interruption is a speech action when one person breaks in to interject while another person is talking. Linguists, social psychologists, anthropologists, and sociologists are among the social scientists who have studied and identified patterns of interruption that may differ by gender, social status, race/ethnicity, culture, and political orientation. |
Heparin-induced thrombocytopenia | Heparin-induced thrombocytopenia (HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant. HIT predisposes to thrombosis (the abnormal formation of blood clots inside a blood vessel). When thrombosis is identified the condition is called heparin-induced thrombocytopenia and thrombosis (HITT). HIT is caused by the formation of abnormal antibodies that activate platelets, which release microparticles that activate thrombin, leading to thrombosis. If someone receiving heparin develops new or worsening thrombosis, or if the platelet count falls, HIT can be confirmed with specific blood tests.The treatment of HIT requires stopping heparin treatment, and both protection from thrombosis and choice of an agent that will not reduce the platelet count any further. Several alternatives are available for this purpose; mainly used are danaparoid, fondaparinux, argatroban, and bivalirudin.While heparin was discovered in the 1930s, HIT was not reported until the 1960s. |
Cycling (ice hockey) | In ice hockey, cycling is an offensive strategy that moves the puck along the boards in the offensive zone to create a scoring chance by making defenders tired or moving them out of position. |
Skeletochronology | Skeletochronology is a technique used to determine the individual, chronological ages of vertebrates by counting lines of arrested, annual growth, also known as LAGs, within skeletal tissues. Within the annual bone growth specimens, there are broad and narrow lines. Broad lines represent the growth period and narrow lines represent a growth pause. These narrow lines are what characterises one growth year, therefore make it suitable to determine the age of the specimen. Not all bones grow at the same rate and the individual growth rate of a bone changes over a lifetime, therefore periodic growth marks can take irregular patterns. This indicates significant chronological events in an individual's life. The use of bone as a biomaterial is useful in investigating structure-property relationships. In addition to current research in skeletochronology, the ability of bone to adapt and change its structure to the external environment provides potential for further research in bone histomorphometry in the future. Amphibians and Reptiles are commonly aged determined, using this method, because they undergo discrete annual activity cycles such as winter dormancy or metamorphosis, however it cannot be used for all species of bony animals. The different environmental and biological factors that influence bone growth and development can become a barrier in determining age as a complete record may be rare. |
Computational number theory | In mathematics and computer science, computational number theory, also known as algorithmic number theory, is the study of computational methods for investigating and solving problems in number theory and arithmetic geometry, including algorithms for primality testing and integer factorization, finding solutions to diophantine equations, and explicit methods in arithmetic geometry.
Computational number theory has applications to cryptography, including RSA, elliptic curve cryptography and post-quantum cryptography, and is used to investigate conjectures and open problems in number theory, including the Riemann hypothesis, the Birch and Swinnerton-Dyer conjecture, the ABC conjecture, the modularity conjecture, the Sato-Tate conjecture, and explicit aspects of the Langlands program. |
Zinc transporter ZIP6 | Zinc transporter ZIP6 is a protein that in humans is encoded by the SLC39A6 gene.Zinc is an essential cofactor for hundreds of enzymes. It is involved in protein, nucleic acid, carbohydrate, and lipid metabolism, as well as in the control of gene transcription, growth, development, and differentiation. SLC39A6 belongs to a subfamily of proteins that show structural characteristics of zinc transporters (Taylor and Nicholson, 2003).[supplied by OMIM] |
NGC 103 | NGC 103 is a small open cluster. It is partially visible in an 8" amateur telescope under moderately light polluted skies. It is roughly 4600 light-years from the Sun. |
Slovak declension | Slovak, like most Slavic languages and Latin, is an inflected language, meaning that the endings (and sometimes also the stems) of most words (nouns, adjectives, pronouns and numerals) change depending on the given combination of the grammatical gender, the grammatical number and the grammatical case of the particular word in the particular sentence: a) Gender: There are four grammatical genders in Slovak: animate masculine, inanimate masculine, feminine, and neuter. In popular description, the first two genders are often covered under common masculine gender. Almost all Slovak nouns and adjectives, as well as some pronouns and numerals can be categorized into one of these genders. Exceptions are pluralia tantum (Vianoce – Christmas, though there are rules for deriving the gender), words that are drifting into another gender and are currently neuter (knieža – prince), and masculine animals that are animate in singular and mostly inanimate in plural. |
Vint | Vint is a Russian card-game, similar to both bridge and whist and it is sometimes referred to as Russian whist. Vint means a screw in Russian, and the name is given to the game because the four players, each in turn, propose, bid and overbid each other until one, having bid higher than the others care to follow, makes the trump, and his vis-a-vis plays as his partner.The game spread to Finland, where it evolved into Skruuvi, which features also a kitty and misère contracts. |
Relapsing polychondritis | Relapsing polychondritis is a multi-systemic condition characterized by repeated episodes of inflammation and deterioration of cartilage. The often painful disease can cause joint deformity and be life-threatening if the respiratory tract, heart valves, or blood vessels are affected. The exact mechanism is poorly understood, but it is thought to be related to an immune-mediated attack on particular proteins that are abundant in cartilage. |
Scarpa's shoe | Scarpa's shoe was an 18th-century mechanical device developed to treat clubfoot. It never became widely accepted.It was designed by Antonio Scarpa, an Italian anatomist and surgeon. |
Mirela Delibegovic | Mirela Delibegovic is a British pharmacologist/biochemist who is Dean for Industrial Engagement in Research & Knowledge Transfer and Director of Aberdeen Cardiovascular and Diabetes Centre. She holds a Personal Chair in Diabetes Physiology and Signalling at the Institute of Medical Sciences at the University of Aberdeen. During the COVID-19 pandemic, Delibegovic used artificial intelligence to develop technologies that would allow mass-screening for coronavirus disease 2019. |
Sample mean and covariance | The sample mean (sample average) or empirical mean (empirical average), and the sample covariance or empirical covariance are statistics computed from a sample of data on one or more random variables. |
Resident monitor | In computing, a resident monitor is a type of system software program that was used in many early computers from the 1950s to 1970s. It can be considered a precursor to the operating system. The name is derived from a program which is always present in the computer's memory, thus being "resident". Because memory was very limited on those systems, the resident monitor was often little more than a stub that would gain control at the end of a job and load a non-resident portion to perform required job cleanup and setup tasks. |
Mask | A mask is an object normally worn on the face, typically for protection, disguise, performance, or entertainment, and often employed for rituals and rites. Masks have been used since antiquity for both ceremonial and practical purposes, as well as in the performing arts and for entertainment. They are usually worn on the face, although they may also be positioned for effect elsewhere on the wearer's body. |
Breaking the bank | In gaming, breaking the bank refers to a player winning a critical sum of money from the casino. The literal, extremely rare, situation of breaking the bank, is winning more than the house has on hand. The term can also be used for the act of winning more chips than there are at the table. Another situation of it portrayed in fiction is a situation where a gambler will win more money than the casino owns, forcing the casino out of business, and winning the casino itself as a prize.In blackjack, card counting can facilitate a winning streak that eventually breaks the bank.Mark Bowden reports in The Atlantic that blackjack player Don Johnson broke the bank in 2011 winning nearly $6 million at Atlantic City's Tropicana casino after previously taking the Borgata for $5 million and Caesars for $4 million. The Tropicana refused to continue playing with Johnson on the terms the casino had negotiated after Johnson won $5.8 million, the Borgata cut Johnson off at $5 million, and the dealer at Caesars refused to fill Johnson's chip tray once his earnings topped $4 million. Johnson had reportedly negotiated terms with the Tropicana that included a hand-shuffled six-deck shoe; the right to split and double down on up to four hands at once; and a “soft 17" whittling the house edge down to one-fourth of 1 percent so in effect, Johnson was playing a 50–50 game against the house, and with the 20% "loss rebate", Johnson was risking only 80 cents of every dollar he played.In 2005, British investor Paul Newey nearly broke the bank at Birmingham's Genting Casino Star City, where he won £3 million and forced owner Stanley Leisure to issue a profit warning and caused the casino value to decline by 12%.Breaking the bank occurs only if the house fails to cap the total amount payable on a winning bet in a way that bears some reasonable relationship to the total amount of money in play. In contrast, parimutuel betting by its very nature does impose such a cap, and hence the bank cannot be broken. |
Speed calling | Speed calling service allows telephone subscribers to assign one or two digit speed calling codes, by dialing a change speed calling list access code, a feature code, and a new telephone number. Thereafter, the subscribers need only use the assigned speed code to reach the desired party rather than dial the long phone number. This service became commonplace in the 1970s with the spread of Stored Program Control exchanges capable of implementing the required databases. It remains useful in installations of many extensions where programming each telephone set would be arduous. Speed calling subscriptions have largely been replaced by the introduction of telephone handsets which incorporate a local version of speed dial. |
MINOS | Main injector neutrino oscillation search (MINOS) was a particle physics experiment designed to study the phenomena of neutrino oscillations, first discovered by a Super-Kamiokande (Super-K) experiment in 1998. Neutrinos produced by the NuMI ("Neutrinos at Main Injector") beamline at Fermilab near Chicago are observed at two detectors, one very close to where the beam is produced (the near detector), and another much larger detector 735 km away in northern Minnesota (the far detector). |
Conservativity | In formal semantics conservativity is a proposed linguistic universal which states that any determiner D must obey the equivalence D(A,B)↔D(A,A∩B) . For instance, the English determiner "every" can be seen to be conservative by the equivalence of the following two sentences, schematized in generalized quantifier notation to the right. |
Η set | In mathematics, an η set (eta set) is a type of totally ordered set introduced by Hausdorff (1907, p. 126, 1914, chapter 6 section 8) that generalizes the order type η of the rational numbers. |
Causal system | In control theory, a causal system (also known as a physical or nonanticipative system) is a system where the output depends on past and current inputs but not future inputs—i.e., the output y(t0) depends only on the input x(t) for values of t≤t0 The idea that the output of a function at any time depends only on past and present values of input is defined by the property commonly referred to as causality. A system that has some dependence on input values from the future (in addition to possible dependence on past or current input values) is termed a non-causal or acausal system, and a system that depends solely on future input values is an anticausal system. Note that some authors have defined an anticausal system as one that depends solely on future and present input values or, more simply, as a system that does not depend on past input values. Classically, nature or physical reality has been considered to be a causal system. Physics involving special relativity or general relativity require more careful definitions of causality, as described elaborately in Causality (physics). |
XMDF (E-book format) | XMDF (ever-eXtending Mobile Document Format) is a file format for viewing electronic books. It was originally developed by Sharp Corporation for its Zaurus platform. It is primarily used in Japan. |
Autecology | Autecology is an approach in ecology that seeks to explain the distribution and abundance of species by studying interactions of individual organisms with their environments. An autecological approach differs from both ecosystem ecology, community ecology (synecology) and population ecology (demecology) by greater recognition of the species-specific adaptations of individual animals, plants or other organisms, and of environmental over density-dependent influences on species distributions. Autecological theory relates the species-specific requirements and environmental tolerances of individuals to the geographic distribution of the species, with individuals tracking suitable conditions, having the capacity for migration at at least one stage in their life cycles. Autecology has a strong grounding in evolutionary theory, including the theory of punctuated equilibrium and the recognition concept of species. |
Tactical beacon | A tactical beacon or TACBE as it is often known to be used by British and American armed forces (usually by Special Forces) for many years. Its primary role is to contact planes or helicopters which may be overhead or nearby.
The system's main use is a distress signal, sending out a constant danger message to AWACS planes. However, it can also be used as a short range communications device with local aircraft. Using it indicates that one is in danger and needs help. |
Zero Install | Zero Install is a means of distributing and packaging software for multiple operating systems (Unix-like including Linux and macOS, Windows). |
Quarter dollar | The term "quarter dollar" refers to a quarter-unit of several currencies that are named "dollar". One dollar ($1) is normally divided into subsidiary currency of 100 cents, so a quarter dollar is equal to 25 cents. These quarter dollars (aka quarters) are denominated as either Coins or as banknotes. Although more than a dozen countries have their own unique dollar currency, not all of them use quarters. This article only includes quarters that were intended for circulation, those that add up to units of dollars, and those in the form of a coin. |
Access Database Engine | The Access Database Engine (also Office Access Connectivity Engine or ACE and formerly Microsoft Jet Database Engine, Microsoft JET Engine or simply Jet) is a database engine on which several Microsoft products have been built. The first version of Jet was developed in 1992, consisting of three modules which could be used to manipulate a database. |
Konqueror | Konqueror is a free and open-source web browser and file manager that provides web access and file-viewer functionality for file systems (such as local files, files on a remote FTP server and files in a disk image). It forms a core part of the KDE Software Compilation. Developed by volunteers, Konqueror can run on most Unix-like operating systems. The KDE community licenses and distributes Konqueror under GNU GPL-2.0-or-later. |
Propane-1,2,3-tricarboxylic acid | Propane-1,2,3-tricarboxylic acid, also known as tricarballylic acid, carballylic acid, and β-carboxyglutaric acid, is a tricarboxylic acid. The compound is an inhibitor of the enzyme aconitase and therefore interferes with the Krebs cycle.Esters of propane-1,2,3-tricarboxylic acid are found in natural products such as the mycotoxins fumonisins B1 and B2 and AAL toxin TA, and in macrocyclic inhibitors of Ras farnesyl-protein transferase (FPTase) such as actinoplanic acid. |
PCTI Solutions | 'PCTI Solutions' is a provider of electronic document management and transfer solutions designed specifically for healthcare organisations in the UK. |
Acoustic scale | In music, the acoustic scale, overtone scale, Lydian dominant scale (Lydian ♭7 scale), or the Mixolydian ♯4 scale is a seven-note synthetic scale. It is the fourth mode of the ascending melodic minor scale.
This differs from the major scale in having an augmented fourth and a minor seventh scale degree. The term "acoustic scale" is sometimes used to describe a particular mode of this seven-note collection (e.g. the specific ordering C–D–E–F♯–G–A–B♭) and is sometimes used to describe the collection as a whole (e.g. including orderings such as E–F♯–G–A–B♭–C–D). |
Get a wiggle on | Get a wiggle on is an 18th century English language idiom and Colloquial Expression which means to move quickly or hurry. |
SYS (command) | In computing, sys is a command used in many operating system command-line shells and also in Microsoft BASIC. |
José A. Carrillo | José Antonio Carrillo de la Plata (pronounced [xoˈse an'tonjo ka'riʎo ðe la 'plata]; born 29 December 1969) is a Spanish mathematician primarily known for his contributions in applied partial differential equations, numerical analysis, many particle systems and kinetic theory. His works make use of methods from functional analysis, calculus of variations, optimal transport, gradient descent and entropy methods. Currently he is Professor of Nonlinear Partial Differential Equations at the Mathematical Institute of the University of Oxford where he started in April 2020. He is also Tutorial Fellow at The Queen's College Oxford in Applied Mathematics. He was previously Chair in Applied and Numerical Analysis at the Department of Mathematics, Imperial College London, United Kingdom, a position he held from October 2012 till March 2020. He served as Chair of the Applied Mathematics Committee of the European Mathematical Society during the period 2014–2017. He was formerly ICREA Research Professor at the Universitat Autònoma de Barcelona, Spain, during the period 2003–2012, and held positions at the University of Granada, Spain, and the University of Texas at Austin, United States during the years 1992–2003. He was recognized with the SeMA prize (2003) and the GAMM Richard Von-Mises prize (2006) for young researchers. He was a holder of the Royal Society Wolfson Fellowship during the period 2012–2017. |
DNA damage-binding protein | DNA damage-binding protein or UV-DDB is a protein complex that is responsible for repair of UV-damaged DNA. This complex is composed of two protein subunits, a large subunit DDB1 (p127) and a small subunit DDB2 (p48). When cells are exposed to UV radiation, DDB1 moves from the cytosol to the nucleus and binds to DDB2, thus forming the UV-DDB complex. This complex formation is highly favorable and it is demonstrated by UV-DDB's binding preference and high affinity to the UV lesions in the DNA. This complex functions in nucleotide excision repair, recognising UV-induced (6-4) pyrimidine-pyrimidone photoproducts and cyclobutane pyrimidine dimers. |
Nalidixic acid | Nalidixic acid (tradenames Nevigramon, NegGram, Wintomylon and WIN 18,320) is the first of the synthetic quinolone antibiotics.
In a technical sense, it is a naphthyridone, not a quinolone: its ring structure is a 1,8-naphthyridine nucleus that contains two nitrogen atoms, unlike quinoline, which has a single nitrogen atom.Synthetic quinolone antibiotics were discovered by George Lesher and coworkers as a byproduct of chloroquine manufacture in the 1960s; nalidixic acid itself was used clinically, starting in 1967.
Nalidixic acid is effective primarily against Gram-negative bacteria, with minor anti-Gram-positive activity. In lower concentrations, it acts in a bacteriostatic manner; that is, it inhibits growth and reproduction. In higher concentrations, it is bactericidal, meaning that it kills bacteria instead of merely inhibiting their growth. |
First-person shooter engine | A first-person shooter engine is a video game engine specialized for simulating 3D environments for use in a first-person shooter video game. First-person refers to the view where the players see the world from the eyes of their characters. Shooter refers to games which revolve primarily around wielding firearms and killing other entities in the game world, either non-player characters or other players. |
Urine flow rate | Urine flow rate or urinary flow rate is the volumetric flow rate of urine during urination. It is a measure of the quantity of urine excreted in a specified period of time (per second or per minute). It is measured with uroflowmetry, a type of flow measurement. |
Glucose-6-phosphate translocase | Glucose-6-phosphate exchanger SLC37A4, also known as glucose-6-phosphate translocase, is an enzyme that in humans is encoded by the SLC37A4 gene.It consists of three subunits, each of which are vital components of the multi-enzyme Glucose-6-Phosphatase Complex (G6Pase). This important enzyme complex is located within the membrane of the endoplasmic reticulum, and catalyzes the terminal reactions in both glycogenolysis and gluconeogenesis. The G6Pase complex is most abundant in liver tissue, but also present in kidney cells, small intestine, pancreatic islets and at a lower concentration in the gallbladder. The G6Pase complex is highly involved in the regulation of homeostasis and blood glucose levels. Within this framework of glucose regulation, the translocase components are responsible for transporting the substrates and products across the endoplasmic reticulum membrane, resulting in the release of free glucose into the bloodstream. |
EIF2S3 | Eukaryotic translation initiation factor 2 subunit 3 (eIF2γ) is a protein that in humans is encoded by the EIF2S3 gene. |
MayaVi | MayaVi is a scientific data visualizer written in Python, which uses VTK and provides a GUI via Tkinter. MayaVi was developed by Prabhu Ramachandran, is free and distributed under the BSD License. It is cross-platform and runs on any platform where both Python and VTK are available (almost any Unix, Mac OS X, or Windows). MayaVi is pronounced as a single name, "Ma-ya-vee", meaning "magical" in Sanskrit. The code of MayaVi has nothing in common with that of Autodesk Maya or the Vi text editor.The latest version of MayaVi, called Mayavi2, is a component of the Enthought suite of scientific Python programs. It differs from the original MayaVi by its strong focus on making not only an interactive program, but also a reusable component for 3D plotting in Python. Although it exposes a slightly different interface and API than the original MayaVi, it now has more features. |
Oxygen balance | Oxygen balance (OB, OB%, or Ω) is an expression that is used to indicate the degree to which an explosive can be oxidized, to determine if an explosive molecule contains enough oxygen to fully oxidize the other atoms in the explosive. For example, fully oxidized carbon forms carbon dioxide, hydrogen forms water, sulfur forms sulfur dioxide, and metals form metal oxides. A molecule is said to have a positive oxygen balance if it contains more oxygen than is needed and a negative oxygen balance if it contains less oxygen than is needed.An explosive with a negative oxygen balance will lead to incomplete combustion, which commonly produces carbon monoxide, which is a toxic gas. Explosives with negative or positive oxygen balance are commonly mixed with other energetic materials that are either oxygen positive or negative, respectively, to increase the explosive's power. For example, TNT is an oxygen negative explosive and is commonly mixed with oxygen positive energetic materials or fuels to increase its power. |
Parade of Homes | The Parade of Homes is a branded showcase of new and remodeled homes held in several regions throughout the United States. Alternatively known as the Tour of Homes in some locales, it is often presented by the local Home Builders Association ("HBA") or Building Industry Association ("BIA"). HBA or BIA home tours under the Parade of Homes showcase homes, both new construction and remodeled homes. Homes generally include single-family homes, condominiums, duplexes, and townhomes. |
Operating speed | The operating speed of a road is the speed at which motor vehicles generally operate on that road. |
Bailout valve | A Bailout valve in underwater diving is a valve switching the breathing gas supply from the primary source to an emergency source.
Rebreather diving#Bailout valve, a rebreather bailout valve is a valve in the mouthpiece that switches from closed to open circuit.
Surface-supplied diving#Bailout gas supply, in surface-supplied diving, a bailout valve is a valve on the helmet, full-face mask or bailout block on the diving harness that switches from surface-supplied gas to scuba gas. |
Post-polio syndrome | Post-polio syndrome (PPS, poliomyelitis sequelae) is a group of latent symptoms of poliomyelitis (polio), occurring at about a 25–40% rate (latest data greater than 80%). These symptoms are caused by the damaging effects of the viral infection on the nervous system. Symptoms typically occur 15 to 30 years after an initial acute paralytic attack. Symptoms include decreasing muscular function or acute weakness with pain and fatigue. The same symptoms may also occur years after a nonparalytic polio (NPP) infection. |
Anesthetic vaporizer | An anesthetic vaporizer (American English) or anaesthetic vaporiser (British English) is a device generally attached to an anesthetic machine which delivers a given concentration of a volatile anesthetic agent. It works by controlling the vaporization of anesthetic agents from liquid, and then accurately controlling the concentration in which these are added to the fresh gas flow. The design of these devices takes account of varying: ambient temperature, fresh gas flow, and agent vapor pressure. |
RNA polymerase V | RNA polymerase V (Pol V), previously known as RNA polymerase IVb, is a multisubunit plant specific RNA polymerase. It is required for normal function and biogenesis of small interfering RNA (siRNA). Together with RNA polymerase IV (Pol IV), Pol V is involved in an siRNA-dependent epigenetic pathway known as RNA-directed DNA methylation (RdDM), which establishes and maintains heterochromatic silencing in plants. |
Hull (watercraft) | A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. |
Lagerdorf Formation | The Lagerdorf Formation is a geologic formation in Germany. It preserves fossils dating back to the Cretaceous period. |
T-statistic | In statistics, the t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error. It is used in hypothesis testing via Student's t-test. The t-statistic is used in a t-test to determine whether to support or reject the null hypothesis. It is very similar to the z-score but with the difference that t-statistic is used when the sample size is small or the population standard deviation is unknown. For example, the t-statistic is used in estimating the population mean from a sampling distribution of sample means if the population standard deviation is unknown. It is also used along with p-value when running hypothesis tests where the p-value tells us what the odds are of the results to have happened. |
Association for Molecular Pathology v. Myriad Genetics, Inc. | Association for Molecular Pathology v. Myriad Genetics, Inc., 569 U.S. 576 (2013), was a Supreme Court case, which decided, that "a naturally occurring DNA segment is a product of nature and not patent eligible merely because it has been isolated.” However, as a "bizzare conciliatory prize" the Court allowed patenting of complementary DNA, which contains exactly the same protein-coding base pair sequence as the natural DNA, albeit with introns removed.The lawsuit in question challenged the validity of gene patents in the United States, specifically questioning certain claims in issued patents owned or controlled by Myriad Genetics that cover isolated DNA sequences, methods to diagnose propensity to cancer by looking for mutated DNA sequences, and methods to identify drugs using isolated DNA sequences. Prior to the case, the U.S. Patent Office accepted patents on isolated DNA sequences as a composition of matter. Diagnostic claims were already under question through the Supreme Court's prior holdings in Bilski v. Kappos and Mayo v. Prometheus. Drug screening claims were not seriously questioned prior to this case. |
Clinical data management system | A clinical data management system or CDMS is a tool used in clinical research to manage the data of a clinical trial. The clinical trial data gathered at the investigator site in the case report form are stored in the CDMS. To reduce the possibility of errors due to human entry, the systems employ various means to verify the data. Systems for clinical data management can be self-contained or part of the functionality of a CTMS. A CTMS with clinical data management functionality can help with the validation of clinical data as well as helps the site employ for other important activities like building patient registries and assist in patient recruitment efforts. |
Braille pattern dots-123456 | The Braille pattern dots-123456 ( ⠿ ) is a 6-dot braille cell with all six dots raised, or an 8-dot braille cell with both dots in the top three rows raised. It is represented by the Unicode code point U+283F, and in Braille ASCII with the equal sign. |
Hsp33 | Hsp33 protein is a molecular chaperone, distinguished from all other known chaperones by its mode of functional regulation. Its activity is redox regulated. Hsp33 is a cytoplasmically localized protein with highly reactive cysteines that respond quickly to changes in the redox environment. Oxidizing conditions like H2O2 cause disulphide bonds to form in Hsp33, a process that leads to the activation of its chaperone function. |
Enumerative combinatorics | Enumerative combinatorics is an area of combinatorics that deals with the number of ways that certain patterns can be formed. Two examples of this type of problem are counting combinations and counting permutations. More generally, given an infinite collection of finite sets Si indexed by the natural numbers, enumerative combinatorics seeks to describe a counting function which counts the number of objects in Sn for each n. Although counting the number of elements in a set is a rather broad mathematical problem, many of the problems that arise in applications have a relatively simple combinatorial description. The twelvefold way provides a unified framework for counting permutations, combinations and partitions. |
Sofosbuvir/daclatasvir | Daclatasvir/sofosbuvir (trade names Darvoni, Sovodak) is a two-drug combination for the treatment of hepatitis C. It is given as a single daily pill containing daclatasvir, a viral NS5A inhibitor, and sofosbuvir, a nucleotide inhibitor of the viral RNA polymerase NS5B.It is on the World Health Organization's List of Essential Medicines. |
Homework coach | A homework coach is a category of a tutor whose mission is to help a student's overall academic success instead of providing remedial instruction in a specific subject. A parent might hire a homework coach when their child is struggling in school, not because they have difficulties with the academic material but because of problems with study skills, organization, executive function skills and motivation. The goal of the coach is to teach the child to become a successful student by learning to plan assignments, organize materials, manage time effectively and, in the case of an ADHD student, learn ways to manage the symptoms of their attention deficit disorder. As such, the role of a homework coach is similar to ADHD coaching but is focused specifically on success in school. Some providers use the term "homework helper" as well as "homework coach." |
Ice cream parlor | Ice cream parlors (American English) or ice cream parlours (British English) are places that sell ice cream, gelato, sorbet, and/or frozen yogurt to consumers. Ice cream is typically sold as regular ice cream (also called hard-packed or hard-serve ice cream), and/or soft serve, which is usually dispensed by a machine with a limited number of flavors (e.g., chocolate, vanilla, and "twist", or "zebra", a mix of the two). Ice cream parlors generally offer a number of flavors and items. Parlors often serve ice cream and other frozen desserts in cones, cups or dishes, the latter two to be eaten with a spoon. Some ice cream parlors prepare ice cream desserts such as sundaes (ice cream topped with syrup, whipped cream and other toppings) or milkshakes, or even a blend (known as a Boston shake). |
Narrator (Windows) | Narrator is a screen reader in Microsoft Windows. Developed by Professor Paul Blenkhorn in 2000, the utility made the Windows operating system more accessible for blind and visually impaired users. |
Maria (reachability analyzer) | Maria: The Modular Reachability Analyzer is a reachability analyzer for concurrent systems that uses Algebraic System Nets (a high-level variant of Petri nets) as its modelling formalism. |
Cellularization | In evolutionary biology, the term cellularization (cellularisation) has been used in theories to explain the evolution of cells, for instance in the pre-cell theory, dealing with the evolution of the first cells on this planet, and in the syncytial theory attempting to explain the origin of Metazoa from unicellular organisms.
Processes of cell development in multinucleate cells (syncytium, plural syncytia) of animals and plants are also termed cellularization, often called syncytium cellularization. |
Cyanobacterin | Cyanobacterin is a chemical compound produced by the cyanobacteria Scytonema hofmanni. It is a photosynthesis inhibitor with algaecidal and herbicidal effects. |
Superman complex | A Superman complex is an unhealthy sense of responsibility, or the belief that everyone else lacks the capacity to successfully perform one or more tasks. Such a person may feel a constant need to "save" others and, in the process, takes on more work on their own.The expression seems to have been first been used by Dr. Fredric Wertham in his 1954 book Seduction of the Innocent and his testimony before the Senate Subcommittee on Juvenile Delinquency. His initial theory focused less on the current allusion to the savior complex and more on people's propensity to find enjoyment in watching someone else beat up another person while they stand by unharmed. He claimed that children reading Superman comic books were exposed to "Fantasies of sadistic joy in seeing other people punished over and over again while you yourself remain immune.” In his discourse of the Superman complex, Wertham also blamed comic books for other social issues such as juvenile delinquency, homosexuality, and Communism. |
Action poetry | Action poetry is a form of poetry that is fierce, unpredictable, and full of energy. It is meant to be read aloud with emphasis and feelings to exhibit the true emotions of the poems. This form of poetry can be found in murals, books, and poetic competitions or recitals such as poetry slam. |
Inflationary epoch | In physical cosmology, the inflationary epoch was the period in the evolution of the early universe when, according to inflation theory, the universe underwent an extremely rapid exponential expansion. This rapid expansion increased the linear dimensions of the early universe by a factor of at least 1026 (and possibly a much larger factor), and so increased its volume by a factor of at least 1078. Expansion by a factor of 1026 is equivalent to expanding an object 1 nanometer (10−9 m, about half the width of a molecule of DNA) in length to one approximately 10.6 light years (about 62 trillion miles) long. |
Deer hunting | Deer hunting is hunting for deer for meat and sport, an activity which dates back tens of thousands of years. Venison, the name for deer meat, is a nutritious and natural food source of animal protein that can be obtained through deer hunting. There are many different types of deer around the world that are hunted for their meat. For sport, often hunters try to kill deer with the largest and most antlers to score them using inches. There are two different categories of antlers. They are typical and nontypical. They measure tine length, beam length, and beam mass by each tine. They will add all these measurements up to get a score. This score is the score without deductions. Deductions occur when the opposite tine is not the same length as it is opposite. That score is the deducted score.Hunting deer is a regulated activity in many territories. In the United States, a state government agency such as a Department of Fish and Wildlife (DFW) or Department of Natural Resources (DNR) oversees the regulations. In the United Kingdom, it is illegal to use bows or rifles chambered in bores smaller than .243 caliber (6mm) for hunting. |
3-MCPD | 3-MCPD (3-monochloropropane-1,2-diol or 3-chloropropane-1,2-diol) is an organic chemical compound with the formula HOCH2CH(OH)CH2Cl. It is a colorless liquid. It is a versatile multifunctional building block. The compound has attracted attention as the most common member of chemical food contaminants known as chloropropanols. It is suspected to be carcinogenic in humans. |
Integration platform | An integration platform is software which integrates different applications and services. It differentiates itself from the enterprise application integration which has a focus on supply chain management. It uses the idea of system integration to create an environment for engineers.
Integration platforms can be built from components, purchased as a pre-built product ready for installation or procured from an integration Platform as a Service (iPaaS) company. |
Winning isn't everything; it's the only thing | "Winning isn’t everything; it's the only thing" is a well-known quotation in sports. It is attributed to UCLA Bruins football coach Henry Russell ("Red") Sanders. He is on record with at least two different versions of the quotation during his coaching career. Sanders is reputed to have used this quote even as far back as the 1930s. |
Soft chemistry | Soft chemistry (also known as chimie douce) is a type of chemistry that uses reactions at ambient temperature in open reaction vessels with reactions similar to those occurring in biological systems. |
Relaxation (physics) | In the physical sciences, relaxation usually means the return of a perturbed system into equilibrium.
Each relaxation process can be categorized by a relaxation time τ. The simplest theoretical description of relaxation as function of time t is an exponential law exp(−t/τ) (exponential decay). |
Knowledge Acquisition and Documentation Structuring | Knowledge Acquisition and Documentation Structuring (KADS) is a structured way of developing knowledge-based systems (expert systems). It was developed at the University of Amsterdam as an alternative to an evolutionary approach and is now accepted as the European standard for knowledge based systems.Its components are: A methodology for managing knowledge engineering projects.
A knowledge engineering workbench.
A methodology for performing knowledge elicitation.KADS was further developed into CommonKADS. |
CloudBolt | CloudBolt is a hybrid cloud management platform developed by CloudBolt Software for deploying and managing virtual machines (VMs), applications, and other IT resources, both in public clouds (e.g., AWS, MS Azure, GCP) and in private data centers (e.g., VMware, OpenStack). |
SDSS J1254+0846 | SDSS J1254+0846 is a face-on binary quasar pair which is in the process of merging. This binary quasar is the first resolved luminous pair to be observed in the act of merging. The pair is composed of two luminous radio-quiet quasars located at redshift z=0.44, being SDSS J125455.09+084653.9 (SDSS J1254+0846 A) and SDSS J125454.87+084652.1 (SDSS J1254+0846 B), or SDSS J1254+0846 collectively. These designations also refer to their host galaxies. This pair provide evidence for the theory that quasars are switched on by galactic collisions. The pair are optically separated by 3.6 arcseconds, giving the real separation as 21 kpc. Tidal tails some 75 kpc have been detected around the galaxies. Thus the two galaxies involved are disc galaxies. The pair was first detected by the Sloan Digital Sky Survey, hence the "SDSS" designations. The tidal tails were first observed by the Magellan Telescopes. A computer simulation by Thomas Cox of the Carnegie Institute corroborated the hypothesis that these were two merging galaxies. This binary quasar, was at the time of discovery in 2010, the lowest redshift binary quasar then observed.Prior to this discovery, all quasars in merging binary pairs either involved one luminous quasar, and a second obscured or dark nucleus, or a spatially unresolved pair of active nuclei. |

7α-Hydroxycholesterol | 7α-Hydroxycholesterol is a precursor of bile acids, created by cholesterol 7α-hydroxylase (CYP7A1). Its formation is the rate-determining step in bile acid synthesis. |
Pseudarthrobacter chlorophenolicus | Pseudarthrobacter chlorophenolicus is a species of bacteria capable of degrading high concentrations of 4-chlorophenol, hence its name. As such, it may be useful in bioremediation. |
A113 | A113 is a studio code and its variants are an inside joke and Easter egg in media developed by alumni of California Institute of the Arts, referring to the classroom used by graphic design and character animation students. |
Pragmatic web | The Pragmatic Web consists of the tools, practices and theories describing why and how people use information. In contrast to the Syntactic Web and Semantic Web the Pragmatic Web is not only about form or meaning of information, but about social interaction which brings about e.g. understanding or commitments.
The transformation of existing information into information relevant to a group of users or an individual user includes the support of how users locate, filter, access, process, synthesize and share information. Social bookmarking is an example of a group tool, end-user programmable agents are examples of individual tools.
The Pragmatic Web idea is rooted in the Language/action perspective. |
Archard equation | The Archard wear equation is a simple model used to describe sliding wear and is based on the theory of asperity contact. The Archard equation was developed much later than Reye's hypothesis (sometimes also known as energy dissipative hypothesis), though both came to the same physical conclusions, that the volume of the removed debris due to wear is proportional to the work done by friction forces. Theodor Reye's model became popular in Europe and it is still taught in university courses of applied mechanics. Until recently, Reye's theory of 1860 has, however, been totally ignored in English and American literature where subsequent works by Ragnar Holm and John Frederick Archard are usually cited. In 1960, Mikhail Mikhailovich Khrushchov and Mikhail Alekseevich Babichev published a similar model as well. In modern literature, the relation is therefore also known as Reye–Archard–Khrushchov wear law. In 2022, the steady-state Archard wear equation was extended into the running-in regime using the bearing ratio curve representing the initial surface topography. |
Offensive counter air | Offensive counter-air (OCA) is a military term for the suppression of an enemy's military air power, primarily through ground attacks targeting enemy air bases: disabling or destroying parked aircraft, runways, fuel facilities, hangars, air traffic control facilities and other aviation infrastructure. Ground munitions like bombs are typically less expensive than more sophisticated air-to-air munitions, and a single ground munition can destroy or disable multiple aircraft in a very short time whereas aircraft already flying must typically be shot down one at a time. Enemy aircraft already flying also represent an imminent threat as they can usually fire back, and therefore destroying them before they can take off minimizes the risk to friendly aircraft. |
Pilocarpine | Pilocarpine is a medication used to reduce pressure inside the eye and treat dry mouth. As an eye drop it is used to manage angle closure glaucoma until surgery can be performed, ocular hypertension, primary open angle glaucoma, and to constrict the pupil after dilation. However, due to its side effects it is no longer typically used for long-term management. Onset of effects with the drops is typically within an hour and lasts for up to a day. By mouth it is used for dry mouth as a result of Sjögren syndrome or radiation therapy.Common side effects of the eye drops include irritation of the eye, increased tearing, headache, and blurry vision. Other side effects include allergic reactions and retinal detachment. Use is generally not recommended during pregnancy. Pilocarpine is in the miotics family of medication. It works by activating cholinergic receptors of the muscarinic type which cause the trabecular meshwork to open and the aqueous humor to drain from the eye.Pilocarpine was isolated in 1874 by Hardy and Gerrard and has been used to treat glaucoma for more than 100 years. It is on the World Health Organization's List of Essential Medicines. It was originally made from the South American plant Pilocarpus. |
