Dwarf galaxy problem
The dwarf galaxy problem, also known as the missing satellites problem, arises from a mismatch between observed dwarf galaxy numbers and collisionless numerical cosmological simulations that predict the evolution of the distribution of matter in the universe. In simulations, dark matter clusters hierarchically, in ever increasing numbers of halo "blobs" as halos' components' sizes become smaller-and-smaller. However, although there seem to be enough observed normal-sized galaxies to match the simulated distribution of dark matter halos of comparable mass, the number of observed dwarf galaxies is orders of magnitude lower than expected from such simulation.
Burning mouth syndrome
Burning mouth syndrome (BMS) is a burning, tingling or scalding sensation in the mouth, lasting for at least four to six months, with no underlying known dental or medical cause. No related signs of disease are found in the mouth. People with burning mouth syndrome may also have a subjective xerostomia (dry mouth sensation where no cause can be found such as reduced salivary flow), paraesthesia (altered sensation such as tingling in the mouth), or an altered sense of taste or smell.A burning sensation in the mouth can be a symptom of another disease when local or systemic factors are found to be implicated; this is not considered to be burning mouth syndrome, which is a syndrome of medically unexplained symptoms. The International Association for the Study of Pain defines burning mouth syndrome as "a distinctive nosological entity characterized by unremitting oral burning or similar pain in the absence of detectable mucosal changes" and "burning pain in the tongue or other oral mucous membranes", and the International Headache Society defines it as "an intra-oral burning sensation for which no medical or dental cause can be found". To ensure the correct diagnosis of burning mouth syndrome, Research Diagnostic Criteria (RDC/BMS) have been developed.Insufficient evidence leaves it unclear if effective treatments exist.
Semitendinosus muscle
The semitendinosus () is a long superficial muscle in the back of the thigh. It is so named because it has a very long tendon of insertion. It lies posteromedially in the thigh, superficial to the semimembranosus.
Hatchet ribozyme
Background: The hatchet ribozyme is an RNA structure that catalyzes its own cleavage at a specific site. In other words, it is a self-cleaving ribozyme. Hatchet ribozymes were discovered by a bioinformatics strategy as RNAs Associated with Genes Associated with Twister and Hammerhead ribozymes, or RAGATH.
Vortex power
Vortex power is a form of hydro power which generates energy by placing obstacles in rivers and oceans to cause the formation of vortices which can then be tapped into a usable form of energy such as electricity. This method is pioneered by a team at the University of Michigan who call the technology VIVACE or Vortex Induced Vibrations Aquatic Clean Energy.
Long-acting beta-adrenoceptor agonist
Long-acting β adrenoceptor agonists (LABAs, more specifically, long-acting β2 adrenergic receptor agonists) are usually prescribed for moderate-to-severe persistent asthma patients or patients with chronic obstructive pulmonary disease (COPD). They are designed to reduce the need for shorter-acting β2 agonists such as salbutamol (albuterol), as they have a duration of action of approximately 12 hours in comparison with the 4-to-6-hour duration of salbutamol, making them candidates for sparing high doses of corticosteroids or treating nocturnal asthma and providing symptomatic improvement in patients with COPD. With the exception of formoterol, long-acting β2 agonists are not recommended for the treatment of acute asthma exacerbations because of their slower onset of action compared to salbutamol. Their long duration of action is due to the addition of a long, lipophilic side-chain that binds to an exosite on adrenergic receptors. This allows the active portion of the molecule to continuously bind and unbind at β2 receptors in the smooth muscle in the lungs.
Product-form solution
In probability theory, a product-form solution is a particularly efficient form of solution for determining some metric of a system with distinct sub-components, where the metric for the collection of components can be written as a product of the metric across the different components. Using capital Pi notation a product-form solution has algebraic form P(x1,x2,x3,…,xn)=B∏i=1nP(xi) where B is some constant. Solutions of this form are of interest as they are computationally inexpensive to evaluate for large values of n. Such solutions in queueing networks are important for finding performance metrics in models of multiprogrammed and time-shared computer systems.

Diffuse leptomeningeal glioneuronal tumor
Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a rare, primary CNS tumor, classified as distinct entity in 2016 and described as diffuse oligodendroglial-like leptomeningeal tumor of children in the 2016 classification of CNS neoplasms by the WHO., Typically, it's considered juvenile tumors but can occur in adults, the average age of diagnosis is five years. It's characterised by wide leptomeningeal spread with male predominance, like histopathology of neurocytoma, oligodendrocyte-like cytopathology, bland appearance, and severe clinical behaviour. Children's basal cisterns and inter-hemispheric fissures are typically involved in plaque like subarachnoid tumors. A common related intraparenchymal lesion is a spinal lesion. However, in certain situations, superficial parenchyma or Virchow-Robin gaps were affected.
Gram domain containing 1b
GRAM domain containing 1B, also known as GRAMD1B, Aster-B and KIAA1201, is a cholesterol transport protein that is encoded by the GRAMD1B gene. It contains a transmembrane region and two domains of known function; the GRAM domain and a VASt domain. It is anchored to the endoplasmic reticulum. This highly conserved gene is found in a variety of vertebrates and invertebrates. Homologs (Lam/Ltc proteins) are found in yeast.
Carbonyl sulfide
Carbonyl sulfide is the chemical compound with the linear formula OCS. It is a colorless flammable gas with an unpleasant odor. It is a linear molecule consisting of a carbonyl group double bonded to a sulfur atom. Carbonyl sulfide can be considered to be intermediate between carbon dioxide and carbon disulfide, both of which are valence isoelectronic with it.
Well-bird exam
A well-bird exam is a check-up for birds which are assumed to be healthy. These examinations are frequently performed by an avian veterinarian when the bird is first acquired and annually thereafter.
Minivan
Minivan (sometimes called simply as van) is a car classification for vehicles designed to transport passengers in the rear seating row(s), with reconfigurable seats in two or three rows. The equivalent classification in Europe is MPV (multi-purpose vehicle). In Southeast Asia, the equivalent classification is Asian Utility Vehicle (AUV).Compared with a full-size van, most minivans are based on a passenger car platform and have a lower body. Early models such as the Ford Aerostar and Chevrolet Astro utilized a compact pickup truck platform. Minivans often have a 'one-box' or 'two-box' body configuration, a higher roof, a flat floor, sliding doors for rear passengers, and high H-point seating. The largest size of minivans is also referred to as 'Large MPV' and became popular following the introduction of the 1984 Dodge Caravan and Renault Espace. Typically, these have platforms derived from D-segment passenger cars or compact pickups. Since the 1990s, the smaller compact MPV and mini MPV sizes of minivans have also become popular.Though predecessors to the minivan date back to the 1930s, the contemporary minivan body style was developed concurrently by several companies in the early 1980s, most notably by Chrysler (producer of the Chrysler minivans) and Renault (the Renault Espace), both first sold for model year 1984. Minivans cut into and eventually overshadowed the traditional market of the station wagon, and grew in global popularity and diversity throughout the 1990s. Since the 2000s, their reception has varied in different parts of the world: in North America, for example, they have been largely eclipsed by crossovers and SUVs, while in Asia they are commonly marketed as luxury vehicles.

Event monitoring
In computer science, event monitoring is the process of collecting, analyzing, and signaling event occurrences to subscribers such as operating system processes, active database rules as well as human operators. These event occurrences may stem from arbitrary sources in both software or hardware such as operating systems, database management systems, application software and processors. Event monitoring may use a time series database.
Polycyclic aromatic hydrocarbon
A polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. The simplest representative is naphthalene, having two aromatic rings and the three-ring compounds anthracene and phenanthrene. PAHs are uncharged, non-polar and planar. Many are colorless. Many of them are found in coal and in oil deposits, and are also produced by the incomplete combustion of organic matter—for example, in engines and incinerators or when biomass burns in forest fires.
Carbonyl cyanide-p-trifluoromethoxyphenylhydrazone
Carbonyl cyanide-p-trifluoromethoxyphenylhydrazone (FCCP) is an ionophore that is a mobile ion carrier. It is referred to as an uncoupling agent because it disrupts ATP synthesis by transporting hydrogen ions through the mitochondrial membrane before they can be used to provide the energy for oxidative phosphorylation. It is a nitrile and hydrazone. FCCP was first described in 1962 by Heytler.
Netarsudil/latanoprost
Netarsudil/latanoprost, sold under the brand name Rocklatan among others, is a fixed-dose combination medication use to treat elevated intraocular pressure (IOP) in people with open-angle glaucoma or ocular hypertension. It contains netarsudil mesylate and latanoprost. It is applied as eye drops to the eyes.The most common side effects include conjunctival hyperaemia (red eye), pain at the site where the medicine was applied, cornea verticillata (deposits in the cornea, the transparent layer in front of the eye that covers the pupil and iris), pruritus (itching of the eye), erythema (reddening) and discomfort in the eye, increased lacrimation (watery eyes), and conjunctival haemorrhage (bleeding in the surface layer of the eye).Netarsudil/latanoprost was approved for medical use in the United States in March 2019, and in the European Union in January 2021.
Datar–Mathews method for real option valuation
The Datar–Mathews Method (DM Method) is a method for real options valuation. The method provides an easy way to determine the real option value of a project simply by using the average of positive outcomes for the project. The method can be understood as an extension of the net present value (NPV) multi-scenario Monte Carlo model with an adjustment for risk aversion and economic decision-making. The method uses information that arises naturally in a standard discounted cash flow (DCF), or NPV, project financial valuation. It was created in 2000 by Vinay Datar, professor at Seattle University; and Scott H. Mathews, Technical Fellow at The Boeing Company.
Logical quality
In many philosophies of logic, statements are categorized into different logical qualities based on how they go about saying what they say. Doctrines of logical quality are an attempt to answer the question: "How many qualitatively different ways are there of saying something?" Aristotle answers, two: you can affirm something of something or deny something of something. Since Frege, the normal answer in the West, is only one, assertion, but what is said, the content of the claim, can vary. For Frege asserting the negation of a claim serves roughly the same role as denying a claim does in Aristotle. Other Western logicians such as Kant and Hegel answer, ultimately three; you can affirm, deny or make merely limiting affirmations, which transcend both affirmation and denial. In Indian logic, four logical qualities have been the norm, and Nagarjuna is sometimes interpreted as arguing for five.
WNT7A
Protein Wnt-7a is a protein that in humans is encoded by the WNT7A gene.
Real data type
A real data type is a data type used in a computer program to represent an approximation of a real number. Because the real numbers are not countable, computers cannot represent them exactly using a finite amount of information. Most often, a computer will use a rational approximation to a real number.
Rocky Mountain Trophy Hunter
Rocky Mountain Trophy Hunter is a series of hunting games developed or published by Sunstorm Interactive.
BCODE
A bCODE is an identifier that can be sent to a mobile phone/device and used as a ticket/voucher/identification or other type of token. The bCODE is an SMS message that can be read electronically from the screen of a mobile device. Bcodes can be sent by text message, and as they are just a standard SMS they can be received on over 99% of all devices.
Bulbus glandis
The bulbus glandis (also called a bulb or knot) is an erectile tissue structure on the penis of canid mammals. During mating, immediately before ejaculation the tissues swell up to lock (tie) the male's penis inside the female. The locking is completed by circular muscles just inside the female's vagina; this is called "the knot" tightening thus preventing the male from withdrawing. The circular muscles also contract intermittently, which has the effect of stimulating ejaculation of sperm, followed by prostatic fluid, as well as maintaining the swelling of the penis and therefore the tie, for some time. For domestic dogs the tie may last up to half an hour or more, though usually less. When male canines are sexually excited, the bulbus glandis may swell up inside the penile sheath, even if the dog has been neutered.The bulbus glandis also occurs in the penises of some pinnipeds, including South American fur seals.
Euclidean relation
In mathematics, Euclidean relations are a class of binary relations that formalize "Axiom 1" in Euclid's Elements: "Magnitudes which are equal to the same are equal to each other."
Heroes of Battle
Heroes of Battle is a hardcover supplement to the 3.5 edition of the Dungeons & Dragons role-playing game.
Strategic Explorations of Exoplanets and Disks with Subaru
Strategic Explorations of Exoplanets and Disks with Subaru (SEEDS) is a multi-year survey that used the Subaru Telescope on Mauna Kea, Hawaii in an effort to directly image extrasolar planets and protoplanetary/debris disks around hundreds of nearby stars. SEEDS is a Japanese-led international project. It consists of some 120 researchers from a number of institutions in Japan, the U.S. and the EU. The survey's headquarters is at the National Astronomical Observatory of Japan (NAOJ) and led by Principal Investigator Motohide Tamura. The goals of the survey are to address the following key issues in the study of extrasolar planets and disks: the detection and census of exoplanets in the regions around solar-mass and massive stars; the evolution of protoplanetary disks and debris disks; and the link between exoplanets and circumstellar disks.
Maxwell (microarchitecture)
Maxwell is the codename for a GPU microarchitecture developed by Nvidia as the successor to the Kepler microarchitecture. The Maxwell architecture was introduced in later models of the GeForce 700 series and is also used in the GeForce 800M series, GeForce 900 series, and Quadro Mxxx series, as well as some Jetson products, all manufactured with TSMC's 28 nm process.The first Maxwell-based products were the GeForce GTX 745 (OEM), GeForce GTX 750, and the GeForce GTX 750 Ti. Both were released on February 18, 2014, both with the chip code number GM107. Earlier GeForce 700 series GPUs had used Kepler chips with the code numbers GK1xx. First-generation Maxwell GPUs (code numbers GM10x) are also used in the GeForce 800M series and the Quadro Kxxx series. A second generation of Maxwell-based products was introduced on September 18, 2014 with the GeForce GTX 970 and GeForce GTX 980, followed by the GeForce GTX 960 on January 22, 2015, the GeForce GTX Titan X on March 17, 2015, and the GeForce GTX 980 Ti on June 1, 2015. The final and lowest spec Maxwell 2.0 card was the GTX950 released on Aug 20th, 2015.
Sclerosing lymphangitis
Sclerosing lymphangitis, also known as lymphangiosclerosis or sclerotic lymphangitis, is a skin condition characterized by a cordlike structure encircling the coronal sulcus of the penis, or running the length of the shaft, that has been attributed to trauma during vigorous sexual play.: 43 Nonvenereal sclerosing lymphangitis is a rare penile lesion consisting of a minimally tender, indurated cord involving the coronal sulcus and occasionally adjacent distal penile skin. The condition involves the hardening of a lymph vessel connected to a vein in the penis. It can look like a thick cord and can feel like a hardened, almost calcified or fibrous, vein, however it tends to not share the common blue tint with a vein. It can be felt as a hardened lump or "vein" even when the penis is flaccid, and is even more prominent during an erection. This disorder is fairly common and most often occurs after vigorous sexual activity and resolves spontaneously.
Grey box model
In mathematics, statistics, and computational modelling, a grey box model combines a partial theoretical structure with data to complete the model. The theoretical structure may vary from information on the smoothness of results, to models that need only parameter values from data or existing literature. Thus, almost all models are grey box models as opposed to black box where no model form is assumed or white box models that are purely theoretical. Some models assume a special form such as a linear regression or neural network. These have special analysis methods. In particular linear regression techniques are much more efficient than most non-linear techniques. The model can be deterministic or stochastic (i.e. containing random components) depending on its planned use.

Alan Mycroft is a professor at the Computer Laboratory, University of Cambridge and a Fellow of Robinson College, Cambridge, where he is also director of studies for computer science.
Hua's lemma
In mathematics, Hua's lemma, named for Hua Loo-keng, is an estimate for exponential sums. It states that if P is an integral-valued polynomial of degree k, ε is a positive real number, and f a real function defined by exp ⁡(2πiP(x)α), then ∫01|f(α)|λdα≪P,εNμ(λ) ,where (λ,μ(λ)) lies on a polygonal line with vertices (2ν,2ν−ν+ε),ν=1,…,k.
Multiomics
Multiomics, multi-omics, integrative omics, "panomics" or "pan-omics" is a biological analysis approach in which the data sets are multiple "omes", such as the genome, proteome, transcriptome, epigenome, metabolome, and microbiome (i.e., a meta-genome and/or meta-transcriptome, depending upon how it is sequenced); in other words, the use of multiple omics technologies to study life in a concerted way. By combining these "omes", scientists can analyze complex biological big data to find novel associations between biological entities, pinpoint relevant biomarkers and build elaborate markers of disease and physiology. In doing so, multiomics integrates diverse omics data to find a coherently matching geno-pheno-envirotype relationship or association. The OmicTools service lists more than 99 softwares related to multiomic data analysis, as well as more than 99 databases on the topic.
P system
For the computer p-System, see UCSD p-System.A P system is a computational model in the field of computer science that performs calculations using a biologically inspired process. They are based upon the structure of biological cells, abstracting from the way in which chemicals interact and cross cell membranes. The concept was first introduced in a 1998 report by the computer scientist Gheorghe Păun, whose last name is the origin of the letter P in 'P Systems'. Variations on the P system model led to the formation of a branch of research known as 'membrane computing.' Although inspired by biology, the primary research interest in P systems is concerned with their use as a computational model, rather than for biological modeling, although this is also being investigated.
ADAM17
A disintegrin and metalloprotease 17 (ADAM17), also called TACE (tumor necrosis factor-α-converting enzyme), is a 70-kDa enzyme that belongs to the ADAM protein family of disintegrins and metalloproteases.
Leafcasting
Leafcasting is a method of strengthening paper so as to preserve it. Leafcasting fills in parts that may be missing in papers by the design of conservators or by age. The process covers an existing sheet of damaged paper with replacement fiber, thus increasing its future usability. The process must be performed on a perfectly calibrated machine to avoid damaging the paper. There are few institutions around the world that have the capabilities to perform leafcasting treatments. As few institutions have the required equipment, leafcasting is not a popular form of paper strengthening.Computerized leafcasting was first employed in the mid-1980s at the Folger Shakespeare Library.
Opium
Opium (or poppy tears, scientific name: Lachryma papaveris) is dried latex obtained from the seed capsules of the opium poppy Papaver somniferum. Approximately 12 percent of opium is made up of the analgesic alkaloid morphine, which is processed chemically to produce heroin and other synthetic opioids for medicinal use and for the illegal drug trade. The latex also contains the closely related opiates codeine and thebaine, and non-analgesic alkaloids such as papaverine and noscapine. The traditional, labor-intensive method of obtaining the latex is to scratch ("score") the immature seed pods (fruits) by hand; the latex leaks out and dries to a sticky yellowish residue that is later scraped off and dehydrated. The word meconium (derived from the Greek for "opium-like", but now used to refer to newborn stools) historically referred to related, weaker preparations made from other parts of the opium poppy or different species of poppies.The production methods have not significantly changed since ancient times. Through selective breeding of the Papaver somniferum plant, the content of the phenanthrene alkaloids morphine, codeine, and to a lesser extent thebaine has been greatly increased. In modern times, much of the thebaine, which often serves as the raw material for the synthesis for oxycodone, hydrocodone, hydromorphone, and other semisynthetic opiates, originates from extracting Papaver orientale or Papaver bracteatum.
Surkål
Surkål ('sour cabbage') is a traditional side dish where the main ingredient is cabbage. It is particularly common in Northern Europe.The cabbage is finely sliced and slowly cooked with caraway and cumin seeds, apple, vinegar, sugar, salt and butter. Surkål is usually served together with pork. Surkål is not to be mistaken for sauerkraut as it does not go through a fermentation process.
Self-paced instruction
Self-paced instruction is any kind of instruction that proceeds based on learner response. The content itself can be curriculum, corporate training, technical tutorials, or any other subject that does not require the immediate response of an instructor. Self-paced instruction is constructed in such a way that the learner proceeds from one topic or segment to the next at their own speed. This type of instruction is becoming increasingly popular as the education world shifts from the classroom to the Internet.
Neodymium(III) sulfide
Neodymium(III) sulfide is a inorganic chemical compound with the formula Nd2S3 composed of a two neodymium atoms in the +3 oxidation state and three sulfur atoms in the +2 oxidation state. Like other rare earth sulfides, neodymium(III) sulfide is used as a high-performance inorganic pigment.
Quarto
Quarto (abbreviated Qto, 4to or 4º) is the format of a book or pamphlet produced from full sheets printed with eight pages of text, four to a side, then folded twice to produce four leaves. The leaves are then trimmed along the folds to produce eight book pages. Each printed page presents as one-fourth size of the full sheet.
Thermonuclear fusion
Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen variants), are combined to form one atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or absorption of energy. This difference in mass arises due to the difference in nuclear binding energy between the atomic nuclei before and after the reaction. Nuclear fusion is the process that powers active or main-sequence stars and other high-magnitude stars, where large amounts of energy are released.
Cycloparaphenylene
A cycloparaphenylene is a molecule that consists of several benzene rings connected by covalent bonds in the para positions to form a hoop- or necklace-like structure. Its chemical formula is [C6H4]n or C6nH4n Such a molecule is usually denoted [n]CPP where n is the number of benzene rings. A cycloparaphenylene can be considered as the smallest possible armchair carbon nanotube, and is a type of carbon nanohoop. Cycloparaphenylenes are challenging targets for chemical synthesis due to the ring strain incurred from forcing benzene rings out of planarity.
G.988
ITU-T Recommendation G.988 defines a management and control interface for optical network units (ONU). It comprises one recommendation:Recommendation ITU-T G.988 specifies the optical network unit (ONU) management and control interface (OMCI) for optical access networks. Recommendation ITU-T G.988 specifies the managed entities (MEs) of a protocol-independent management information base (MIB) that models the exchange of information between an optical line termination (OLT) and an ONU. In addition, it covers the ONU management and control channel, protocol and detailed messages.
Cooperstown cocktail
The Cooperstown cocktail refers to a panel of four drug probes used in human pharmacokinetic studies to determine the activity of drug metabolising enzymes. The terminology 'cocktail' refers to the fact that the drug probes are given together. The Cooperstown cocktail consists of four drugs that are considered specific substrates for four cytochrome P450 (CYP) isoforms. One of the drugs (caffeine) provides, through its metabolites, substrates for two additional enzymes.
APUD cell
APUD cells (DNES cells) constitute a group of apparently unrelated endocrine cells, which were named by the scientist A.G.E. Pearse, who developed the APUD concept in the 1960s based on calcitonin-secreting parafollicular C cells of dog thyroid. These cells share the common function of secreting a low molecular weight polypeptide hormone. There are several different types which secrete the hormones secretin, cholecystokinin and several others. The name is derived from an acronym, referring to the following: Amine Precursor Uptake – for high uptake of amine precursors including 5-hydroxytryptophan (5-HTP) and dihydroxyphenylalanine (DOPA).
Fractal dimension on networks
Fractal analysis is useful in the study of complex networks, present in both natural and artificial systems such as computer systems, brain and social networks, allowing further development of the field in network science.
Bit field
A bit field is a data structure that consists of one or more adjacent bits which have been allocated for specific purposes, so that any single bit or group of bits within the structure can be set or inspected. A bit field is most commonly used to represent integral types of known, fixed bit-width, such as single-bit Booleans.
Video DownloadHelper
Video DownloadHelper is an extension for the Firefox web browser and Chrome web browser. It allows the user to download videos from sites that stream videos through HTTP. The extension was developed by Michel Gutierrez.
Serotonergic cell groups
Serotonergic cell groups refer to collections of neurons in the central nervous system that have been demonstrated by histochemical fluorescence to contain the neurotransmitter serotonin (5-hydroxytryptamine). Since they are for the most part localized to classical brainstem nuclei, particularly the raphe nuclei, they are more often referred to by the names of those nuclei than by the B1-9 nomenclature. These cells appear to be common across most mammals and have two main regions in which they develop; one forms in the mesencephlon and the rostral pons and the other in the medulla oblongata and the caudal pons.Nine serotonergic cell groups have been identified.
Ecogrid
Ecogrid, known as Ecoraster to most of Europe, is a type of plastic, permeable paving grid used in the construction of parking lots, walkways and other outdoor surfaces. Ecogrid is marketed as a green technology because it is designed to reduce harmful stormwater runoff and is made with post-consumer plastic to reduce waste. Ecoraster was trade marked by Purus Plastics in 2008.Ecogrid is made from specially selected plastics that are recycled in their Bavarian production centre. It has a locking mechanism that secures one grid to the next. There are many fill types for this kind of grid system but mainly they are: Grass Gravel Resin bound stone Resin bound rubber crumb Soil
Doravirine/lamivudine/tenofovir
Doravirine/lamivudine/tenofovir, sold under the brand name Delstrigo, is a fixed-dose combination antiretroviral medication for the treatment of HIV/AIDS. It contains doravirine, lamivudine, and tenofovir disoproxil. It is taken by mouth.In the United States, it was approved by the Food and Drug Administration (FDA) for the treatment of HIV-1 infection in August 2018.
N-acetylserotonin O-methyltransferase-like protein
N-acetylserotonin O-methyltransferase-like protein is an enzyme that in humans is encoded by the ASMTL gene.
Curve complex
In mathematics, the curve complex is a simplicial complex C(S) associated to a finite-type surface S, which encodes the combinatorics of simple closed curves on S. The curve complex turned out to be a fundamental tool in the study of the geometry of the Teichmüller space, of mapping class groups and of Kleinian groups. It was introduced by W.J.Harvey in 1978.
Yoke
A yoke is a wooden beam sometimes used between a pair of oxen or other animals to enable them to pull together on a load when working in pairs, as oxen usually do; some yokes are fitted to individual animals. There are several types of yoke, used in different cultures, and for different types of oxen. A pair of oxen may be called a yoke of oxen, and yoke is also a verb, as in "to yoke a pair of oxen". Other animals that may be yoked include horses, mules, donkeys, and water buffalo.
Euparal
Euparal is a synthetic microscopy mountant originally formulated in 1904 by Professor G. Gilson, the professor of Zoology at Louvain University, Louvain, Belgium. It has been manufactured by several companies, but is now exclusively manufactured by ASCO Laboratories, Manchester, England.
Pain
Pain is a distressing feeling often caused by intense or damaging stimuli. The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage."Pain motivates organisms to withdraw from damaging situations, to protect a damaged body part while it heals, and to avoid similar experiences in the future. Most pain resolves once the noxious stimulus is removed and the body has healed, but it may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease.Pain is the most common reason for physician consultation in most developed countries. It is a major symptom in many medical conditions, and can interfere with a person's quality of life and general functioning. People in pain experience impaired concentration, working memory, mental flexibility, problem solving and information processing speed, and are more likely to experience irritability, depression and anxiety. Simple pain medications are useful in 20% to 70% of cases. Psychological factors such as social support, cognitive behavioral therapy, excitement, or distraction can affect pain's intensity or unpleasantness.
Paper cutter
A paper cutter, also known as a paper guillotine or simply a guillotine, is a tool often found in offices and classrooms. It is designed to administer straight cuts to single sheets or large stacks of paper at once.

Cat skin disorders are among the most common health problems in cats. Skin disorders in cats have many causes, and many of the common skin disorders that afflict people have a counterpart in cats. The condition of a cat's skin and coat can also be an important indicator of its general health. Skin disorders of cats vary from acute, self-limiting problems to chronic or long-lasting problems requiring life-time treatment. Cat skin disorders may be grouped into categories according to the causes.
Goodell's sign
In medicine, Goodell's sign is an indication of pregnancy. It is a significant softening of the vaginal portion of the cervix from increased vascularization. This vascularization is a result of hypertrophy and engorgement of the vessels below the growing uterus. This sign occurs at approximately six weeks' gestation. The sign is named after William Goodell (1829–1874).

In 2022, he was one of 121 prominent Australians banned from travelling to Russia indefinitely for his outspoken criticism of the use of AI by the Russian military.
Creative work
A creative work is a manifestation of creative effort including fine artwork (sculpture, paintings, drawing, sketching, performance art), dance, writing (literature), filmmaking, and composition.
Sheave
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and the cable or belt. In case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave or pulley wheel.
Deligne–Mumford stack
In algebraic geometry, a Deligne–Mumford stack is a stack F such that Pierre Deligne and David Mumford introduced this notion in 1969 when they proved that moduli spaces of stable curves of fixed arithmetic genus are proper smooth Deligne–Mumford stacks. If the "étale" is weakened to "smooth", then such a stack is called an algebraic stack (also called an Artin stack, after Michael Artin). An algebraic space is Deligne–Mumford. A key fact about a Deligne–Mumford stack F is that any X in F(B) , where B is quasi-compact, has only finitely many automorphisms. A Deligne–Mumford stack admits a presentation by a groupoid; see groupoid scheme.
Bowl-out
A bowl-out (sometimes termed a bowl-off) was used as a tiebreaker in various forms of limited overs cricket to decide a match that would otherwise end in a tie. Five bowlers from each side deliver one or two balls each at an unguarded wicket (three stumps). If each team has hit the same number of wickets after the first five bowlers per side, the bowling continues and is decided by sudden death.
Hallucinogenic mushroom
Hallucinogenic mushrooms are those mushrooms that have hallucinogenic effects on humans. Such mushrooms include: Psychoactive Amanita mushroom Psilocybin mushroom
Brightness temperature
Brightness temperature or radiance temperature is a measure of the intensity of electromagnetic energy coming from a source. In particular, it is the temperature at which a black body would have to be in order to duplicate the observed intensity of a grey body object at a frequency ν This concept is used in radio astronomy, planetary science, materials science and climatology.The brightness temperature provides "a more physically recognizable way to describe intensity."When the electromagnetic radiation observed is thermal radiation emitted by an object simply by virtue of its temperature, then the actual temperature of the object will always be equal to or higher than the brightness temperature. The actual temperature will be higher than the brightness temperature if the emissivity of the object is greater than 1.
Snub disphenoid
In geometry, the snub disphenoid, Siamese dodecahedron, triangular dodecahedron, trigonal dodecahedron, or dodecadeltahedron is a convex polyhedron with twelve equilateral triangles as its faces. It is not a regular polyhedron because some vertices have four faces and others have five. It is a dodecahedron, one of the eight deltahedra (convex polyhedra with equilateral triangle faces), and is the 84th Johnson solid (non-uniform convex polyhedra with regular faces). It can be thought of as a square antiprism where both squares are replaced with two equilateral triangles.
Mitochondrial myopathy
Mitochondrial myopathies are types of myopathies associated with mitochondrial disease. On biopsy, the muscle tissue of patients with these diseases usually demonstrate "ragged red" muscle fibers. These ragged-red fibers contain mild accumulations of glycogen and neutral lipids, and may show an increased reactivity for succinate dehydrogenase and a decreased reactivity for cytochrome c oxidase. Inheritance was believed to be maternal (non-Mendelian extranuclear). It is now known that certain nuclear DNA deletions can also cause mitochondrial myopathy such as the OPA1 gene deletion. There are several subcategories of mitochondrial myopathies.
SERPIN A12
Serpin A12 (OL-64, Vaspin, Visceral adipose-specific serpin, Ser A12) is a glycoprotein that is a class A member of the serine protease inhibitor (serpin) family. In humans, Serpin A12 is encoded by the SERPINA12 gene.First discovered in 2005, Serpin A12 was highly expressed in white adipose tissue of Otsuka Long Evans Tokushima Fatty Rats at the same time that the rats' obesity and insulin plasma levels reached a peak, at around 30 weeks old. Eventually, it was found to be expressed in visceral and subcutaneous adipose tissue of obese humans, leading the protein to be linked with obesity, glucose metabolism, and insulin resistance.
NAS Award for Chemistry in Service to Society
The NAS Award for Chemistry in Service to Society is awarded by the U.S. National Academy of Sciences "for contributions to chemistry, either in fundamental science or its application, that clearly satisfy a societal need." It has been awarded every two years since its inception in 1991.
Staircase paradox
In mathematical analysis, the staircase paradox is a pathological example showing that limits of curves do not necessarily preserve their length. It consists of a sequence of "staircase" polygonal chains in a unit square, formed from horizontal and vertical line segments of decreasing length, so that these staircases converge uniformly to the diagonal of the square. However, each staircase has length two, while the length of the diagonal is the square root of 2, so the sequence of staircase lengths does not converge to the length of the diagonal. Martin Gardner calls this "an ancient geometrical paradox". It shows that, for curves under uniform convergence, the length of a curve is not a continuous function of the curve.For any smooth curve, polygonal chains with segment lengths decreasing to zero, connecting consecutive vertices along the curve, always converge to the arc length. The failure of the staircase curves to converge to the correct length can be explained by the fact that some of their vertices do not lie on the diagonal. In higher dimensions, the Schwarz lantern provides an analogous example showing that polyhedral surfaces that converge pointwise to a curved surface do not necessarily converge to its area, even when the vertices all lie on the surface.As well as highlighting the need for careful definitions of arc length in mathematics education, the paradox has applications in digital geometry, where it motivates methods of estimating the perimeter of pixelated shapes that do not merely sum the lengths of boundaries between pixels.

Virescence
Virescence is the abnormal development of green pigmentation in plant parts that are not normally green, like shoots or flowers (in which case it is known as floral virescence). Virescence is closely associated with phyllody (the abnormal development of flower parts into leaves) and witch's broom (the abnormal growth of a dense mass of shoots from a single point). They are often symptoms of the same disease affecting the plants, typically those caused by phytoplasmas. The term chloranthy is also sometimes used for floral virescence, though it is more commonly used for phyllody.The term was coined around 1825, from Latin virescere, "to become green". In the English language the term virescent may also refer to greenness (cf. verdant).
Oseledets theorem
In mathematics, the multiplicative ergodic theorem, or Oseledets theorem provides the theoretical background for computation of Lyapunov exponents of a nonlinear dynamical system. It was proved by Valery Oseledets (also spelled "Oseledec") in 1965 and reported at the International Mathematical Congress in Moscow in 1966. A conceptually different proof of the multiplicative ergodic theorem was found by M. S. Raghunathan. The theorem has been extended to semisimple Lie groups by V. A. Kaimanovich and further generalized in the works of David Ruelle, Grigory Margulis, Anders Karlsson, and François Ledrappier.

Problem-Oriented Medical Information System
The Problem-Oriented Medical Information System, or PROMIS, was a hypertext system specially designed for maintaining health care records. PROMIS was developed at the University of Vermont in 1976, primarily by Jan Schultz and Dr. Lawrence Weed, M.D. Apparently, the developers of Carnegie Mellon University's ZOG system were so impressed with PROMIS that it reinspired them to return to their own work. PROMIS was an interactive, touchscreen system that allowed users to access a medical record within a large body of medical knowledge. At its peak, the PROMIS system had over 60,000 frames of knowledge. PROMIS was also known for its fast responsiveness, especially for its time.
Circular analysis
In statistics, circular analysis is the selection of the details of a data analysis using the data that is being analysed. It is often referred to as double dipping, as one uses the same data twice. Circular analysis unjustifiably inflates the apparent statistical strength of any results reported and, at the most extreme, can lead to the apparently significant result being found in data that consists only of noise. In particular, where an experiment is implemented to study a postulated effect, it is a misuse of statistics to initially reduce the complete dataset by selecting a subset of data in ways that are aligned to the effects being studied. A second misuse occurs where the performance of a fitted model or classification rule is reported as a raw result, without allowing for the effects of model-selection and the tuning of parameters based on the data being analyzed.
Sennichite
Sennichite (千日手, lit. "moves (for) a thousand days") or repetition draw is a rule in shogi stating that the game will end in a draw if the same position is repeated four times during a game as long as the repetitions do not involve checks.
Anti-tank mine
In anti-tank warfare, an anti-tank mine (abbreviated to "AT mine") is a type of land mine designed to damage or destroy vehicles including tanks and armored fighting vehicles. Compared to anti-personnel mines, anti-tank mines typically have a much larger explosive charge, and a fuze designed to be triggered by vehicles or, in some cases, remotely or by tampering with the mine.
Semi-invariant of a quiver
In mathematics, given a quiver Q with set of vertices Q0 and set of arrows Q1, a representation of Q assigns a vector space Vi to each vertex and a linear map V(α): V(s(α)) → V(t(α)) to each arrow α, where s(α), t(α) are, respectively, the starting and the ending vertices of α. Given an element d ∈ N Q0, the set of representations of Q with dim Vi = d(i) for each i has a vector space structure.
Cajun accordion
A Cajun accordion (in Cajun French: accordéon), also known as a squeezebox, is single-row diatonic button accordion used for playing Cajun music.
Input hypothesis
The input hypothesis, also known as the monitor model, is a group of five hypotheses of second-language acquisition developed by the linguist Stephen Krashen in the 1970s and 1980s. Krashen originally formulated the input hypothesis as just one of the five hypotheses, but over time the term has come to refer to the five hypotheses as a group. The hypotheses are the input hypothesis, the acquisition–learning hypothesis, the monitor hypothesis, the natural order hypothesis and the affective filter hypothesis. The input hypothesis was first published in 1977.The hypotheses put primary importance on the comprehensible input (CI) that language learners are exposed to. Understanding spoken and written language input is seen as the only mechanism that results in the increase of underlying linguistic competence, and language output is not seen as having any effect on learners' ability. Furthermore, Krashen claimed that linguistic competence is only advanced when language is subconsciously acquired, and that conscious learning cannot be used as a source of spontaneous language production. Finally, learning is seen to be heavily dependent on the mood of the learner, with learning being impaired if the learner is under stress or does not want to learn the language.
Used car
A used car, a pre-owned vehicle, or a secondhand car, is a vehicle that has previously had one or more retail owners. Used cars are sold through a variety of outlets, including franchise and independent car dealers, rental car companies, buy here pay here dealerships, leasing offices, auctions, and private party sales. Some car retailers offer "no-haggle prices," "certified" used cars, and extended service plans or warranties.

It is designed for document indexers, organizations that want to describe the content of their documents or of their products and services, as well as anyone who wants to clarify vocabulary in English and French as part of their work or research.
Dysprosium titanate
Dysprosium titanate (Dy2Ti2O7) is an inorganic compound, a ceramic of the titanate family, with pyrochlore structure. Dysprosium titanate, like holmium titanate and holmium stannate, is a spin ice material. In 2009, quasiparticles resembling magnetic monopoles were observed at low temperature and high magnetic field.Dysprosium titanate (Dy2TiO5) is used since 1995 as material for control rods of commercial nuclear reactor.
Raw device
In computing, specifically in Unix and Unix-like operating systems, a raw device is a special kind of logical device associated with a character device file that allows a storage device such as a hard disk drive to be accessed directly, bypassing the operating system's caches and buffers (although the hardware caches might still be used). Applications like a database management system can use raw devices directly, enabling them to manage how data is cached, rather than deferring this task to the operating system.
IOE engine
The intake/inlet over exhaust, or "IOE" engine, known in the US as F-head, is a four-stroke internal combustion engine whose valvetrain comprises OHV inlet valves within the cylinder head and exhaust side-valves within the engine block.IOE engines were widely used in early motorcycles, initially with the inlet valve being operated by engine suction instead of a cam-activated valvetrain. When the suction-operated inlet valves reached their limits as engine speeds increased, the manufacturers modified the designs by adding a mechanical valvetrain for the inlet valve. A few automobile manufacturers, including Willys, Rolls-Royce and Humber also made IOE engines for both cars and military vehicles. Rover manufactured inline four and six cylinder engines with a particularly efficient version of the IOE induction system.
Penbutolol
Penbutolol (brand names Levatol, Levatolol, Lobeta, Paginol, Hostabloc, Betapressin) is a medication in the class of beta blockers, used in the treatment of high blood pressure. Penbutolol is able to bind to both beta-1 adrenergic receptors and beta-2 adrenergic receptors (the two subtypes), thus making it a non-selective β blocker.: Table 10–2, p 252  Penbutolol is a sympathomimetic drug with properties allowing it to act as a partial agonist at β adrenergic receptors.It was approved by the FDA in 1987 and was withdrawn from the US market by January 2015.
Amur virus
Amur virus (AMRV) is a zoonotic negative-sense single-stranded RNA virus. It may be a member of the genus Orthohantavirus, but it has not be definitively classified as a species and may only be a strain. It has been identified as a causative agent of hemorrhagic fever with renal syndrome.
Cross-phase modulation
Cross-phase modulation (XPM) is a nonlinear optical effect where one wavelength of light can affect the phase of another wavelength of light through the optical Kerr effect. When the optical power from a wavelength impacts the refractive index, the impact of the new refractive index on another wavelength is known as XPM.
