17α-Ethynyl-3α-androstanediol | 17α-Ethynyl-3α-androstanediol (developmental code names HE-3235, Apoptone), also known as 17α-ethynyl-5α-androstane-3α,17β-diol, is a synthetic androstane steroid and a 17α-substituted derivative of 3α-androstanediol which was never marketed. It was under development for the treatment of prostate cancer but was discontinued.17α-Ethynyl-3α-androstanediol itself shows very low affinity for steroid receptors, including the AR, ERα, ERβ, PR, and GR, and its mechanism of action is not well-characterized. It produces 5α-dihydroethisterone (5α-dihydro-17α-ethynyltestosterone), a ligand of several steroid hormone receptors, and 17α-ethynyl-3β-androstanediol, an estrogen, as active metabolites. These metabolites may contribute importantly to the biological activity of 17α-ethynyl-3α-androstanediol, with 17α-ethynyl-3α-androstanediol potentially serving as a prodrug. |
Macroorchidism | Macroorchidism is a disorder found in males, specifically in children, where a subject has abnormally large testes. The condition is commonly inherited in connection with fragile X syndrome (FXS), which is also the second most common genetic cause of intellectual disability. The condition is also a rare sign of the McCune-Albright syndrome. The opposite of macroorchidism is called microorchidism, which is the condition of abnormally small testes. |
Ovarian plexus | The ovarian plexus arises from the renal plexus, and is distributed to the ovary, and fundus of the uterus.
It is carried in the suspensory ligament of the ovary. |
Maui solar telescope protests | The Maui solar telescope protests are a series of protests and demonstrations attempting to block the construction of the Daniel K. Inouye Solar Telescope on the summit of Haleakalā in Maui, Hawaii. |
Mr. ZIP | Mr. ZIP, informally "Zippy", is a cartoon character used in the 1960s by the United States Post Office Department, and later by its successor, the United States Postal Service, to encourage the general public to include the ZIP Code in all mailings. |
Stack resource policy | The Stack Resource Policy (SRP) is a resource allocation policy used in real-time computing, used for accessing shared resources when using earliest deadline first scheduling. It was defined by T. P. Baker. SRP is not the same as the Priority ceiling protocol which is for fixed priority tasks (FP). |
Transfer line | A transfer line is a manufacturing system which consists of a predetermined sequence of machines connected by an automated material handling system and designed for working on a very small family of parts. Parts can be moved singularly because there’s no need for batching when carrying parts between process stations (as opposed to a job shop for example). The line can synchronous, meaning that all parts advance with the same speed, or asynchronous, meaning buffers exist between stations where parts wait to be processed. Not all transfer lines must geometrically be straight lines, for example circular solutions have been developed which make use of rotary tables, however using buffers becomes almost impossible. |
Peptide PHI | Peptide PHI, also known as peptide histidine isoleucine, is a peptide which functions as a hormone. This peptide contains a composition of 27 amino acids with histidine on the N-terminus and isoleucine on the C-terminus. It was originally isolated from the mammalian small intestine amongst mammalian neurons called intramural neurons which function in the motor activity of the intestinal walls. An example of this was revealed in a study that demonstrated that this peptide regulates water and electrolyte transportation in the human jejunum; similar to its inhibitory effects on fluid absorption in the small intestine of pigs and rats.Peptide histidine isoleucine (PHI) is part of family that plays a vital role in the cell growth rate such as in the intestine as well as in brain. It was derived from glucagon family called the pituitary adenylate cyclase-activating polypeptide (PACAP) and it has an amino acid sequence homology to vasoactive intestinal peptide, secretin, glucagon, and other growth hormone releasing factor. Human studies have shown that the release of PHI into the stomach regulates the neuroendocrine cell processes that affect gastrointestinal physiology. This peptide is present within the central nervous system that help regulate food consumption behavior, while at peripheral nervous system this peptide accumulates in the stomach which controls the digestion of food.It also plays a role in the regulation of prolactin in humans. It functions specifically function in the G protein signaling pathway through G protein, which is a transmembrane protein that causes the cascade phosphorylation. It is located throughout the entire length of intestine while PHI is mostly concentrated in the colon region. |
Semiregular variable star | In astronomy, a semiregular variable star, a type of variable star, is a giant or supergiant of intermediate and late (cooler) spectral type showing considerable periodicity in its light changes, accompanied or sometimes interrupted by various irregularities. Periods lie in the range from 20 to more than 2000 days, while the shapes of the light curves may be rather different and variable with each cycle. The amplitudes may be from several hundredths to several magnitudes (usually 1-2 magnitudes in the V filter). |
Strapwork | In the history of art and design, strapwork is the use of stylised representations in ornament of ribbon-like forms. These may loosely imitate leather straps, parchment or metal cut into elaborate shapes, with piercings, and often interwoven in a geometric pattern. In early examples there may or may not be three-dimensionality, either actual in curling relief ends of the elements, or just represented in two dimensions. As the style continued, these curling elements became more prominent, often turning into scrollwork, where the ends curl into spirals or scrolls. By the Baroque scrollwork was a common element in ornament, often partly submerged by other rich ornament. |
Sorbitan monostearate | Sorbitan monostearate is an ester of sorbitan (a sorbitol derivative) and stearic acid and is sometimes referred to as a synthetic wax. |
Comparison of issue-tracking systems | Notable issue tracking systems, including bug tracking systems, help desk and service desk issue tracking systems, as well as asset management systems, include the following. The comparison includes client-server application, distributed and hosted systems. |
Sushi Ramen Riku | Sushi Ramen Riku (すしらーめん《りく》, born Riku Horiuchi, 30 May 1999 in Tokyo) is a Japanese YouTube personality who had worked for Uuum Co. His channel has over 5 million subscribers and has been awarded with the Silver and Gold YouTube Play Button. The origin of its name is due to his two favorite foods, sushi and ramen.Riku's videos generally feature contrived practical stunts and experiments, often conceived supposedly to aid everyday convenience, such as building a rig to take off his pants using pressurized air or to break world records such as using a massive rubberband slingshot to catapult him while riding an office chair. Riku also films his occasional pranks on family members.He started making videos for YouTube in junior high school, where he was part of a group called "Sushi Ramen" with some classmates. After graduating, he attended to a different high school from his classmates and then he started working alone, although keeping the same name. Even after graduating, Riku and his friends were prohibited from broadcasting videos showing their respective schools, which led to the pixilation of several of their videos. He opened his main channel, Sushi Ramen Riku, on 23 October 2013, where he makes mostly experimental videos. On 21 May 2015, he opened a subchannel called Sushi Ramen 2nd. |
Nofence | Nofence is a Norwegian company that makes GPS collars for farm animals (cattle, sheep, and goats) that discourage them from crossing virtual fences.Oscar Hovde Berntsen has been working on the idea of virtual fencing, as an alternative to fixed electric fencing, since the 1990s. Nofence was incorporated in 2011. In 2016, there was a pilot project in Norway with 850 goats. In 2017, the Norwegian Food Safety Authority approved the use of Nofence for goats; and for cattle and sheep in 2020. Nofence are based in Batnfjordsøra, Norway, with a UK office in Warwick.The solar-powered collars play a melody "ringtone" when the animal reaches the fence, and if they continue, a small shock, as with an electric fence. Farmers can use a mobile app to change boundaries throughout the day, and avoid over-grazing. Fenceless grazing is being supported by conservationists and farmers, particularly in sensitive areas or difficult upland areas where physical fencing would be impractical, expensive or inappropriate.In September 2020, The Times reported that trials were being conducted at six sites in the UK, including Epping Forest, in Essex.In December 2020, Nofence stated that 17,000 collars were in use in Norway. |
Terrestrial Planet Finder | The Terrestrial Planet Finder (TPF) was a proposed project by NASA to construct a system of space telescopes for detecting extrasolar terrestrial planets. TPF was postponed several times and finally cancelled in 2011. There were two telescope systems under consideration, the TPF-I, which had several small telescopes, and TPF-C, which used one large telescope. |
Argument-dependent name lookup | In the C++ programming language, argument-dependent lookup (ADL), or argument-dependent name lookup, applies to the lookup of an unqualified function name depending on the types of the arguments given to the function call. This behavior is also known as Koenig lookup, as it is often attributed to Andrew Koenig, though he is not its inventor.During argument-dependent lookup, other namespaces not considered during normal lookup may be searched where the set of namespaces to be searched depends on the types of the function arguments. Specifically, the set of declarations discovered during the ADL process, and considered for resolution of the function name, is the union of the declarations found by normal lookup with the declarations found by looking in the set of namespaces associated with the types of the function arguments. |
Fifth-week event | A fifth week event is a novelty comic book promotion.
Comic publishers schedule releases in four-week cycles, releasing on a particular day of the week (e.g., every Wednesday). In the event that a month has more than four weeks (i.e., a fifth Wednesday), publishers often sell unusual comics to fill in the scheduling gap.
The fifth week event has been discontinued since longer crossovers, such as Blackest Night, run for months at a time, requiring more tie-ins and fewer simultaneous crossovers. |
Certified Video Engineer | Certified Video Engineer (CEV) is a title granted to an individual that successfully meets the experience and examination requirements of the certification. The certification is regulated by the Society of Broadcast Engineers. The CEV title is protected by copyright laws. Individuals who use the title without consent from the Society of Broadcast Engineers could face legal action.
The SBE certifications were created to recognize individuals who practice in career fields which are not regulated by state licensing programs. Video engineering is not a concern of civil or governmental regulation. |
Acedianthrone | Acedianthrone is an octacyclic relative of anthraquinone that is used as a pigment. It is produced from anthrone by condensation with glyoxal followed by dehydrogenation. |
Eyeline match | An eyeline match is a film editing technique associated with the continuity editing system. It is based on the premise that an audience will want to see what the character on-screen is seeing. An eyeline match begins with a character looking at something off-screen, followed by a cut of another object or person: for example, a shot showing a man looking off-screen is followed by a shot of a television. Given the audience's initial interest in the man's gaze, it is generally implied on the basis of the second shot that the man in the first was looking at the television, even though the man is never seen looking at the television within the same shot.Alfred Hitchcock's Rear Window, for example, makes frequent use of eyeline matches. The main character, played by James Stewart, is confined to his apartment and often looks out its rear window at events in the buildings across from him. Hitchcock frequently cuts from Stewart looking off-screen to various people and events that are assumed to be the focus of his gaze.Eyeline match also refers to the practice of setting off-camera eyelines for single shots of characters within a scene such that, when these shots are cut together, each of the characters appear to be looking at the correct character, without any confusion. Factors influencing the position of the off-camera eyeline (usually by placing the other actors off camera but sometimes by giving the on-camera actor a mark to look at) include the 180 degree rule, camera lens/height/distance to subject and geography of the set. For instance, matching close-ups of two actors in a scene would be shot on the same lens with the camera placed at a matching height (either the same height, or at the off-camera actor's height or the on-camera actor's height) and distance, with the off-camera actor positioned equidistant from the lens and on opposite sides so that Actor A looks off camera right and Actor B looks off camera left. |
Jason's cradle | A Jason's cradle is a maritime rescue device. The device is similar to a scramble net made of cloth webbing. It can be suspended over a rail, but it has stiffener batts which make it easier to climb. It can take the form of a hammock or stretcher for the rescue of weakened or injured people when the "top" and "bottom" of the net are lowered to the water level so they can simply roll into it. Different sizes are available, both for pleasure craft as well as for maritime search and rescue applications. |
Plant perception (physiology) | Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption, sound, and touch. The scientific study of plant perception is informed by numerous disciplines, such as plant physiology, ecology, and molecular biology. |
Studio manager | Studio manager, studio director, or studio head is a job title in various media-related professions, including design, advertising, and broadcasting. |
Vibration-proof hitch | The vibration-proof hitch is a knot used for fastening a line or rope to a solid object. This particular hitch is designed to tighten when subjected to vibration and functions best when the object is fairly large compared to the diameter of the rope. Knot expert Geoffrey Budworth credits the knot to Amory Bloch Lovins. |
Flow measurement | Flow measurement is the quantification of bulk fluid movement. Flow can be measured using devices called flowmeters in various ways. The common types of flowmeters with industrial applications are listed below: Obstruction type (differential pressure or variable area) Inferential (turbine type) Electromagnetic Positive-displacement flowmeters, which accumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. |
Optimized Systems Software | Optimized Systems Software (OSS) was a company that produced disk operating systems, programming languages with integrated development environments, and applications primarily for the Atari 8-bit family of home computers. OSS was best known for their enhanced versions of Atari DOS (OS A+, then DOS XL), Atari BASIC (first BASIC A+, then BASIC XL, and BASIC XE), and the Atari Assembler Editor (EASMD, then MAC/65), all of which were substantially improved over Atari's products, as well as the Action! programming language. OSS also sold some software for the Apple II.OSS transitioned to 16-bit platforms with Personal Pascal for the Atari ST and Personal Prolog for Macintosh (which was also advertised for the Atari ST, but may not have been released). OSS was not as significant in those markets. |
Selenide iodide | The selenide iodides are chemical compounds that contain both selenide ions (Se2−) and iodide ions (I−) and one or metal atoms. They are in the class of mixed anion compounds or chalcogenide halides.Some related compounds do not actually contain a selenide ion, instead containing an iodoselenium cation. These cations include SeI3+, Se2I42+, Se6I22+, and polymeric Se6I+. |
HIV tropism | HIV tropism refers to the cell type in which the human immunodeficiency virus (HIV) infects and replicates. HIV tropism of a patient's virus is measured by the Trofile assay.
HIV can infect a variety of cells such as CD4+ helper T-cells and macrophages that express the CD4 molecule on their surface. HIV-1 entry to macrophages and T helper cells is mediated not only through interaction of the virion envelope glycoproteins (gp120) with the CD4 molecule on the target cells but also with its chemokine coreceptors. |
Harmonic and Individual Lines and Noise | Harmonic and Individual Lines and Noise (HILN) is a parametric codec for audio. The basic premise of the encoder is that most audio, and particularly speech, can be synthesized from only sinusoids and noise. The encoder describes individual sinusoids with amplitude and frequency, harmonic tones by fundamental frequency, amplitude and the spectral envelope of the partials, and the noise by amplitude and spectral envelope. This type of encoder is capable of encoding audio to between 6 and 16 kilobits per second for a typical audio bandwidth of 8 kHz. The framelength of this encoder is 32 ms. |
L-AP4 | L-AP4 (L-2-amino-4-phosphonobutyric acid) is a drug used in scientific research, which acts as a group-selective agonist for the group III metabotropic glutamate receptors (mGluR4/6/7/8). It was the first ligand found to act as an agonist selective for this group of mGlu receptors, but does not show selectivity between the different mGluR Group III subtypes. It is widely used in the study of this receptor family and their various functions. |
Sartorite | Sartorite is a lead arsenic sulfide with the chemical formula PbAs2S4 and as type locality the Lengenbach Quarry in Legenbach, Binnental, Valais, Switzerland. Historically, sartorite has been thought isomorphic to chalcostibite, emplectite, and zinckenite, but was definitively distinguished from the others in 1939. |
Single-wing formation | In American and Canadian football, a single-wing formation was a precursor to the modern spread or shotgun formation. The term usually connotes formations in which the snap is tossed rather than handed—formations with one wingback and a handed snap are commonly called "wing T" or "winged T".
Created by Glenn "Pop" Warner, the single wing was superior to the T formation in its ability to get an extra eligible receiver down field. |
Tissue stress | Tissue stress (tissue adaptive syndrome) is an unspecific adaptive reaction universal for all tissues of adult organism which forms in tissue as a response to various external influences. The latter are tissue cells’ damage, overload of their specialized functions or regulatory influences. |
Backtracking | Backtracking is a class of algorithms for finding solutions to some computational problems, notably constraint satisfaction problems, that incrementally builds candidates to the solutions, and abandons a candidate ("backtracks") as soon as it determines that the candidate cannot possibly be completed to a valid solution.The classic textbook example of the use of backtracking is the eight queens puzzle, that asks for all arrangements of eight chess queens on a standard chessboard so that no queen attacks any other. In the common backtracking approach, the partial candidates are arrangements of k queens in the first k rows of the board, all in different rows and columns. Any partial solution that contains two mutually attacking queens can be abandoned. |
Adjunction space | In mathematics, an adjunction space (or attaching space) is a common construction in topology where one topological space is attached or "glued" onto another. Specifically, let X and Y be topological spaces, and let A be a subspace of Y. Let f : A → X be a continuous map (called the attaching map). One forms the adjunction space X ∪f Y (sometimes also written as X +f Y) by taking the disjoint union of X and Y and identifying a with f(a) for all a in A. Formally, X∪fY=(X⊔Y)/∼ where the equivalence relation ~ is generated by a ~ f(a) for all a in A, and the quotient is given the quotient topology. As a set, X ∪f Y consists of the disjoint union of X and (Y − A). The topology, however, is specified by the quotient construction. Intuitively, one may think of Y as being glued onto X via the map f. |
Notification system | In information technology, a notification system is a combination of software and hardware that provides a means of delivering a message to a set of recipients. It commonly shows activity related to an account. Such systems constitute an important aspect of modern Web applications.For example, a notification system can send an e-mail announcing when a computer network will be down for a scheduled maintenance. |
Telephone keypad | A telephone keypad is a keypad installed on a push-button telephone or similar telecommunication device for dialing a telephone number. It was standardized when the dual-tone multi-frequency signaling (DTMF) system was developed in the Bell System in the United States in the 1960s that replaced rotary dialing originally developed in electromechanical switching systems. Because of the installed abundance of rotary dial equipment well into the 1990s, many telephone keypads were also designed to produce loop-disconnect pulses electronically, and some could be optionally switched to produce either DTMF or pulses. |
Totarol | Totarol is a naturally produced diterpene that is bioactive as totarol. It was first isolated by McDowell and Easterfield from the heartwood of Podocarpus totara, a conifer tree found in New Zealand. Podocarpus totara was investigated for unique molecules due to the tree's increased resistance to rotting. Recent studies have confirmed totarol's unique antimicrobial and therapeutic properties. Consequently, totarol is a candidate for a new source of drugs and has been the goal of numerous syntheses. |
Anisopoikilocytosis | Anisopoikilocytosis is a medical condition illustrated by a variance in size (anisocytosis) and shape (poikilocytosis) of a red blood cell. The underlying cause can be attributed to various anemias, most often; beta thalassemia major, a form of microcytic anemia. In β thalassemia major the beta hemoglobin chain is completely absent, rendering an increase in fetal hemoglobin (HbF). |
Magneto | A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current. Unlike a dynamo, a magneto does not contain a commutator to produce direct current. It is categorized as a form of alternator, although it is usually considered distinct from most other alternators, which use field coils rather than permanent magnets. |
Telemark (waltz) | The Telemark is a ballroom dance step; in waltz competition, it is in the Silver syllabus. Telemarks are reverse turns where the follower (the lady) does a heel turn as the leader (the man) travels around her. There are similar Telemarks in foxtrot and quickstep.The term Telemark is borrowed from skiing, in which a turn is generated by a forward leg motion. The closed Telemark and open Telemark are fairly similar. However, the closed Telemark ends in closed position, while the open Telemark ends in promenade position. |
Voltage droop | Voltage droop is the intentional loss in output voltage from a device as it drives a load. Adding droop in a voltage regulation circuit increases the headroom for load transients.
All electrical systems have some amount of resistance between the regulator output and the load. At high currents, even a small resistance results in substantial voltage drop between the regulator and the load. Conversely, when the output current is (near) zero, the voltage at the load is higher. This follows from Ohm's law. |
Twease | Twease is an open source biomedical web search engine which searches MEDLINE. |
Etch pit density | The etch pit density (EPD) is a measure for the quality of semiconductor wafers. |
Estimation lemma | In mathematics the estimation lemma, also known as the ML inequality, gives an upper bound for a contour integral. If f is a complex-valued, continuous function on the contour Γ and if its absolute value |f (z)| is bounded by a constant M for all z on Γ, then |∫Γf(z)dz|≤Ml(Γ), where l(Γ) is the arc length of Γ. In particular, we may take the maximum := sup z∈Γ|f(z)| as upper bound. Intuitively, the lemma is very simple to understand. If a contour is thought of as many smaller contour segments connected together, then there will be a maximum |f (z)| for each segment. Out of all the maximum |f (z)|s for the segments, there will be an overall largest one. Hence, if the overall largest |f (z)| is summed over the entire path then the integral of f (z) over the path must be less than or equal to it. |
Blackface | Blackface is a form of theatrical makeup used predominantly by non-black people to portray a caricature of a black person. |
Tetraphenylborate | Tetraphenylborate (IUPAC name: Tetraphenylboranuide) is an organoboron anion consisting of a central boron atom with four phenyl groups. Salts of tetraphenylborate uncouple oxidative phosphorylation. |
4-Phenyl-1,2,4-triazole-3,5-dione | 4-Phenyl-1,2,4-triazoline-3,5-dione (PTAD) is an azodicarbonyl compound. PTAD is one of the strongest dienophiles and reacts rapidly with dienes in Diels-Alder reactions. The most prominent use of PTAD was the first synthesis of prismane in 1973. |
ORC5 | Origin recognition complex subunit 5 is a protein that in humans is encoded by the ORC5 (ORC5L) gene. |
Modesty in medical settings | Modesty in medical settings refers to the practices and equipment used to preserve patient modesty in medical examination and clinics. |

The purpose of these libraries is to allow developers to: Parse EDXL Messages from a string or underlying stream Programmatically create EDXL messages Validate EDXL Messages to the schema Validate that EDXL Messages conform to the additional business rules specified in the standards documentation Write EDXL messages to a string or underlying stream |
MIPModDB | MIPModDB is a database of comparative protein structure models of MIP (Major intrinsic proteins) family of proteins. |
RIPK3 | Receptor-interacting serine/threonine-protein kinase 3 is an enzyme that is encoded by the RIPK3 gene in humans.The product of this gene is a member of the receptor-interacting protein (RIP) family of serine/threonine protein kinases. It contains a C-terminal domain unique from other RIP family members. The encoded protein is predominantly localized to the cytoplasm, and can undergo nucleocytoplasmic shuttling dependent on novel nuclear localization and export signals. It is a component of the tumor necrosis factor (TNF) receptor-I signaling complex, and can induce necroptosis by interaction with RIPK1 and MLKL in a protein complex termed the necrosome. Interactions between RIPK1 and RIPK3 also form a necrosome, which triggers apoptosis. |
Hippocampal replay | Hippocampal replay is a phenomenon observed in rats, mice, cats, rabbits, songbirds and monkeys. |
Ballpark | A ballpark, or baseball park, is a type of sports venue where baseball is played. The playing field is divided into the infield, an area whose dimensions are rigidly defined, and the outfield, where dimensions can vary widely from place to place. A larger ballpark may also be called a baseball stadium because it shares characteristics of other outdoor stadiums. |
TAF6 | Transcription initiation factor TFIID subunit 6 is a protein that in humans is encoded by the TAF6 gene. |
Go-go | Go-go is a subgenre of funk music with an emphasis on specific rhythmic patterns, and live audience call and response. |
Parseval's identity | In mathematical analysis, Parseval's identity, named after Marc-Antoine Parseval, is a fundamental result on the summability of the Fourier series of a function. Geometrically, it is a generalized Pythagorean theorem for inner-product spaces (which can have an uncountable infinity of basis vectors).
Informally, the identity asserts that the sum of squares of the Fourier coefficients of a function is equal to the integral of the square of the function, where the Fourier coefficients cn of f are given by More formally, the result holds as stated provided f is a square-integrable function or, more generally, in Lp space L2[−π,π]. |
Defense Visual Information Distribution Service | The Defense Visual Information Distribution Service (DVIDS), formerly the Defense Video & Imagery Distribution System, is an operation supported by the Defense Media Activity (DMA). It provides a connection between world media and the American military personnel serving at home and abroad. It supports all branches of the U.S. military as well as its coalition partners in the Central Command (CENTCOM) area of responsibility. |
Cry room | A cry room or crying room is a space designed for people to take babies or small children for privacy or to reduce the disturbance of others. Started in the 1950s, they are usually found in churches, theatres, and cinemas. In some venues, they are called "infant care rooms". Cry rooms are often designed with soundproofing properties to dampen the sounds made within. Many are equipped with a speaker system to allow the occupants to continue to listen to the main presentation, be it a church service or performance in a theatre.Some churches have cry rooms for when a child becomes "out of control, disruptive enough to distract people, or makes it hard for others to hear or contemplate". Cry rooms are used in theatres and cinemas to allow a child to be taken out of the main auditorium while still allowing the accompanying adult to watch the performance.There are hardly any cry rooms anymore, particularly in cinemas, which is mainly due to the rise of multiplex theaters beginning in the 1970s. |
Microfluidics in chemical biology | Microfluidics in chemical biology is the application of microfluidics in the study of chemical biology. |
Weighted-knuckle glove | Weighted-knuckle gloves, also called sap gloves, are a type of weapon used in hand to hand combat. They consist of a pair of ordinary looking gloves usually made of leather or a synthetic material, with powdered lead or steel sewn into a special pouch covering the knuckles, and often the backs of the fingers and the back of the hand. In some designs, this distinctive feature is obvious, while in others it is almost completely indistinguishable from an ordinary glove, allowing the gloves to be worn in plain sight without suspicion. |
Mensch Computer | The Mensch Computer is a personal computer system produced by the Western Design Center (WDC). It is based on the WDC 65C265 microcontroller, which implements the instruction sets of two microprocessors: the 16-bit W65C816/65816, and the 8-bit 6502. The computer is named after Bill Mensch, designer of the 6502 and subsequent series of microprocessor. |
Microbial inoculant | Microbial inoculants also known as soil inoculants or bioinoculants are agricultural amendments that use beneficial rhizosphericic or endophytic microbes to promote plant health. Many of the microbes involved form symbiotic relationships with the target crops where both parties benefit (mutualism). While microbial inoculants are applied to improve plant nutrition, they can also be used to promote plant growth by stimulating plant hormone production. Although bacterial and fungal inoculants are common, inoculation with archaea to promote plant growth is being increasingly studied. Research into the benefits of inoculants in agriculture extends beyond their capacity as biofertilizers. Microbial inoculants can induce systemic acquired resistance (SAR) of crop species to several common crop diseases (provides resistance against pathogens). So far SAR has been demonstrated for powdery mildew (Blumeria graminis f. sp. hordei, Heitefuss, 2001), take-all (Gaeumannomyces graminis var. tritici, Khaosaad et al., 2007), leaf spot (Pseudomonas syringae, Ramos Solano et al., 2008) and root rot (Fusarium culmorum, Waller et al. 2005). |
Small nucleolar RNA J26 | In molecular biology, the Small nucleolar RNA J26 is a non-coding RNA (ncRNA) molecule identified in rice (Oryza sativa) which functions in the modification of other small nuclear RNAs (snRNAs). This type of modifying RNA is usually located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis. It is known as a small nucleolar RNA (snoRNA) and also often referred to as a guide RNA. |
B3GAT1 | 3-beta-glucuronosyltransferase 1 (B3GAT1) is an enzyme that in humans is encoded by the B3GAT1 gene, whose enzymatic activity creates the CD57 epitope on other cell surface proteins. In immunology, the CD57 antigen (CD stands for cluster of differentiation) is also known as HNK1 (human natural killer-1) or LEU7. It is expressed as a carbohydrate epitope that contains a sulfoglucuronyl residue in several adhesion molecules of the nervous system. |
XTEA | In cryptography, XTEA (eXtended TEA) is a block cipher designed to correct weaknesses in TEA. The cipher's designers were David Wheeler and Roger Needham of the Cambridge Computer Laboratory, and the algorithm was presented in an unpublished technical report in 1997 (Needham and Wheeler, 1997). It is not subject to any patents.Like TEA, XTEA is a 64-bit block Feistel cipher with a 128-bit key and a suggested 64 rounds. Several differences from TEA are apparent, including a somewhat more complex key-schedule and a rearrangement of the shifts, XORs, and additions. |
Ethnoecology | Ethnoecology is the scientific study of how different groups of people living in different locations understand the ecosystems around them, and their relationships with surrounding environments. |
Gland of Zeis | Glands of Zeis are unilobar sebaceous glands located on the margin of the eyelid. The glands of Zeis service the eyelash. These glands produce an oily substance that is issued through the excretory ducts of the sebaceous lobule into the middle portion of the hair follicle. In the same area of the eyelid, near the base of the eyelashes are apocrine glands called the "glands of Moll". |
Rota's conjecture | Rota's excluded minors conjecture is one of a number of conjectures made by mathematician Gian-Carlo Rota. It is considered to be an important problem by some members of the structural combinatorics community. Rota conjectured in 1971 that, for every finite field, the family of matroids that can be represented over that field has only finitely many excluded minors.
A proof of the conjecture has been announced by Geelen, Gerards, and Whittle. |
Channel bank | In telecommunications, a channel bank is a device that performs multiplexing or demultiplexing ("demux") of a group of communications channels, such as analog or digital telephone lines, into one channel of higher bandwidth or higher digital bit rate, such as a DS-1 (T1) circuit, so that all the channels can be sent simultaneously over a single cable called a trunkline. |
Kono Aozora ni Yakusoku o | Kono Aozora ni Yakusoku o (この青空に約束を―, "The Promise I made over this Blue Sky") is a Japanese adult visual novel produced by Giga, originally released on March 31, 2006. The game was ported to the PlayStation 2 in 2007, the PlayStation Portable in 2009, and the PlayStation Vita in 2015 came with additional content although the adult content was removed. An anime television series was made in 2007 under the title Kono Aozora ni Yakusoku o: Yōkoso Tsugumi Ryō e (この青空に約束を― ～ようこそつぐみ寮へ～, lit. "The Promise I made over this Blue Sky ~ Welcome to the Tsugumi Dorm ~"). |
Esophageal varices | Esophageal varices are extremely dilated sub-mucosal veins in the lower third of the esophagus. They are most often a consequence of portal hypertension, commonly due to cirrhosis. People with esophageal varices have a strong tendency to develop severe bleeding which left untreated can be fatal. Esophageal varices are typically diagnosed through an esophagogastroduodenoscopy. |
Tilidine | Tilidine, Leart or tilidate (brand names: Tilidin, Valoron, Tetova, Hitleart and Valtran) is a synthetic opioid painkiller, used mainly in Belgium, Bulgaria, Germany, Luxembourg, South Africa and Switzerland for the treatment of moderate to severe pain, both acute and chronic. Its onset of pain relief after oral administration is about 10–15 minutes and peak relief from pain occurs about 25–50 minutes after oral administration. |
Hash-based cryptography | Hash-based cryptography is the generic term for constructions of cryptographic primitives based on the security of hash functions. It is of interest as a type of post-quantum cryptography. |
Lune (geometry) | In plane geometry, a lune (from Latin luna 'moon') is the concave-convex region bounded by two circular arcs. It has one boundary portion for which the connecting segment of any two nearby points moves outside the region and another boundary portion for which the connecting segment of any two nearby points lies entirely inside the region. A convex-convex region is termed a lens.Formally, a lune is the relative complement of one disk in another (where they intersect but neither is a subset of the other). Alternatively, if A and B are disks, then A∖A∩B is a lune. |
Sustained Spheromak Physics Experiment | The Sustained Spheromak Physics Experiment (SSPX) is a program at Lawrence Livermore National Laboratory in the United States established to investigate spheromak plasma.A spheromak device produces a plasma in magnetohydrodynamic equilibrium mainly through self-induced plasma currents, as opposed to a tokamak device which depends on large externally generated magnetic fields. The series of experiments examines the potential for a spheromak device to contain fusion fuel. According to a 1999 abstract, The Sustained Spheromak Physics Experiment, SSPX , will study spheromak physics with particular attention to energy confinement and magnetic fluctuations in a spheromak sustained by electrostatic helicity injection. |
Brontes Technologies | Brontes Technologies, Inc. was a startup company that produced a digital dental impression system brought to market by 3M as The Lava Chairside Oral Scanner C.O.S. The Lava C.O.S. provides a powerful connection and improved productivity for a doctor and their dental lab thereby enabling the needed input to mass customized lab production in the dental market.Brontes Technologies, Inc. was born out of the research of Massachusetts Institute of Technology lecturer Janos Rohaly (Chief Scientist), professor Douglas Hart, and two graduate students from the MIT Department of Mechanical Engineering, Federico Frigerio and Sheng Tan. After three years of research, the inventing team received a grant from Deshpande Center for Technological Innovation at MIT to shift the focus of its work toward commercial opportunities.In Autumn 2002, the inventing team recruited co-founders Eric Paley as CEO and Micah Rosenbloom as COO, both Harvard Business School students, to evaluate the commercial potential of the technology, develop a business plan and raise capital. In May 2003, the combined team was selected as the runner-up in the MIT 50K and Harvard Business School Business Plan Competitions. Brontes Technologies was incorporated in June 2003 and identified the dental market as its business focus on the summer of 2003. The company was funded in 2004 by David Frankel, Flybridge Capital, Charles River Ventures, and Bain Capital Ventures. Brontes Technologies innovated 3D-In-Motion technology which allowed the dentist to scan the inside of the mouth by moving an instrument above the teeth and capturing accurate high resolution data in real-time. In October 2006, Brontes Technologies was acquired by 3M Company for $95 million and the product was launched to the dental market in 2007. |
Neo-minimalism | Neo-minimalism is an amorphous art movement of the late 20th and early 21st centuries. It has alternatively been called Neo-Geometric or "Neo-Geo" art. Other terms include: Neo-Conceptualism, Neo-Futurism, Neo-Op, Neo-pop, New Abstraction, Poptometry, Post-Abstractionism, and Smart Art. |
Zeigarnik effect | Named after Lithuanian-Soviet psychologist Bluma Zeigarnik, in psychology the Zeigarnik effect occurs when an activity that has been interrupted may be more readily recalled. It postulates that people remember unfinished or interrupted tasks better than completed tasks. In Gestalt psychology, the Zeigarnik effect has been used to demonstrate the general presence of Gestalt phenomena: not just appearing as perceptual effects, but also present in cognition.The Zeigarnik effect should not be confused with the Ovsiankina effect. Maria Ovsiankina, a colleague of Zeigarnik, investigated the effect of task interruption on the tendency to resume the task at the next opportunity. |
IBM Lotus Symphony | IBM Lotus Symphony is a discontinued suite of applications for creating, editing, and sharing text, spreadsheet, presentations, and other documents and browsing the World Wide Web. It was first distributed as commercial proprietary software, then as freeware, before IBM contributed the suite to the Apache Software Foundation in 2014 for inclusion in the free and open-source Apache OpenOffice software suite.First released in 2007, the suite has a name similar to the 1980s DOS Lotus Symphony suite, but the two software suites are otherwise unrelated. The previous Lotus application suite, Lotus SmartSuite, is also unrelated. |
Ambipolar diffusion | Ambipolar diffusion (ambipolar: relating to or consisting of both electrons and positive ions moving in opposite directions) is diffusion of positive and negative species with opposite electrical charge due to their interaction via an electric field. In the case of ionic crystals, the fluxes of the diffusing species are coupled, while in a plasma the various species diffuse at the same rate. |
JCB Dieselmax | The JCB Dieselmax is a streamliner car designed for the purpose of breaking the land speed record for a diesel-engined vehicle.
The car was built for JCB, a British multinational equipment company. As of 2018, the car holds the world diesel-powered land speed record, having been driven to over 350 miles per hour (560 km/h) by Wing Commander Andy Green in 2006. |
Luhn mod N algorithm | The Luhn mod N algorithm is an extension to the Luhn algorithm (also known as mod 10 algorithm) that allows it to work with sequences of values in any even-numbered base. This can be useful when a check digit is required to validate an identification string composed of letters, a combination of letters and digits or any arbitrary set of N characters where N is divisible by 2. |
Satralizumab | Satralizumab, sold under the brand name Enspryng, is a humanized monoclonal antibody medication that is used for the treatment of neuromyelitis optica spectrum disorder (NMOSD), a rare autoimmune disease. The drug is being developed by Chugai Pharmaceutical, a subsidiary of Roche.The most common side effects include the common cold (nasopharyngitis), headache, upper respiratory tract infection, inflammation of the lining of the stomach, rash, joint pain, extremity pain, fatigue and nausea.Satralizumab regulates inflammation by inhibiting the interleukin-6 (IL-6) receptor, a key mediator of the immune response.Satralizumab was approved for medical use in the United States in August 2020, and in the European Union in June 2021. The US Food and Drug Administration (FDA) considers it to be a first-in-class medication. |
Leica X2 | The Leica X2 is a digital large sensor compact camera announced by Leica Camera on 10 May 2012. It is the successor of the Leica X1, and improves on the earlier model with a higher resolution sensor, improved autofocus and an optionally available electronic viewfinder for easier use in bright light.On 16 September 2014, the Leica X-E was announced, which is identical to the X2 except the exterior colour. |
Vascular disease | Vascular disease is a class of diseases of the vessels of the circulatory system in the body, including blood vessels – the arteries and veins, and the lymphatic vessels. Vascular disease is a subgroup of cardiovascular disease. Disorders in this vast network of blood and lymph vessels can cause a range of health problems that can sometimes become severe, and fatal. Coronary heart disease for example, is the leading cause of death for men and women in the United States. |
Sagittal sulcus | The sagittal sulcus is a midline groove that runs across the internal surfaces of part of the squamous part of the frontal bone, the parietal bones, and part of the occipital bones. The sagittal sulcus accommodates the superior sagittal sinus. The falx cerebri attaches to the edge of the sagittal sulcus on either side.On the inferior portion of the squamous part of the frontal bone, the edges of the sagittal sinus converge to form a single midline ridge, the frontal crest (which also gives attachment to the falx cerebri). |
Skeeter syndrome | Skeeter syndrome (papular urticaria) is a localized severe allergic reaction to mosquito bites, consisting of inflammation, peeling skin, hives, ulceration and sometimes fever. It is caused by allergenic polypeptides in mosquito saliva, and therefore is not contagious. It is one of several forms, being one of the most severe, of allergic responses to mosquito bites, termed mosquito bite allergies.The condition may vary between individuals based on the reaction size and severity. Some individuals may experience reactions only to some bites and not others, thought to be attributed to varying reactions to different species of mosquitoes. |
Suit jacket | A suit jacket, also called a lounge jacket, lounge coat or suit coat, is a jacket in classic menswear that is part of a suit. |
Craniodiaphyseal dysplasia | Craniodiaphyseal dysplasia (CDD), also known as lionitis, is an extremely rare autosomal recessive bone disorder that causes calcium to build up in the skull, disfiguring the facial features and reducing life expectancy.
These calcium deposits decrease the size of cranial foramina, and can decrease the circumference of the cervical spinal canal. In the few cases recorded, most died in childhood. |
Clipper chip | The Clipper chip was a chipset that was developed and promoted by the United States National Security Agency (NSA) as an encryption device that secured "voice and data messages" with a built-in backdoor that was intended to "allow Federal, State, and local law enforcement officials the ability to decode intercepted voice and data transmissions." It was intended to be adopted by telecommunications companies for voice transmission. Introduced in 1993, it was entirely defunct by 1996. |
Phytomenadione | Phytomenadione, also known as vitamin K1 or phylloquinone, is a vitamin found in food and used as a dietary supplement. It is on the World Health Organization's List of Essential Medicines.As a supplement it is used to treat certain bleeding disorders. This includes warfarin overdose, vitamin K deficiency, and obstructive jaundice. It is also recommended to prevent and treat vitamin K deficiency bleeding in infants. Use is typically recommended by mouth, intramuscular injection or injection under the skin. When given by injection benefits are seen within two hours. Many countries in the world choose intramuscular injections in newborn to keep them safe from severe bleeding (VKDB). It is considered a safe treatment and saves many children from death and severe neurologic deficit every year.Side effects when given by injection may include pain at the site of injection. Severe allergic reactions may occur when it is injected into a vein or muscle, but this has mainly happened when large doses of a certain type of supplement containing castor oil were given intravenously. Use during pregnancy is considered safe, use is also likely okay during breastfeeding. It works by supplying a required component for making a number of blood clotting factors. Food sources include green vegetables, vegetable oil, and some fruit.Phytomenadione was first isolated in 1939. In 1943 Edward Doisy and Henrik Dam were given a Nobel Prize for its discovery. |
Stable isotope ratio | The term stable isotope has a meaning similar to stable nuclide, but is preferably used when speaking of nuclides of a specific element. Hence, the plural form stable isotopes usually refers to isotopes of the same element. The relative abundance of such stable isotopes can be measured experimentally (isotope analysis), yielding an isotope ratio that can be used as a research tool. Theoretically, such stable isotopes could include the radiogenic daughter products of radioactive decay, used in radiometric dating. However, the expression stable-isotope ratio is preferably used to refer to isotopes whose relative abundances are affected by isotope fractionation in nature. This field is termed stable isotope geochemistry. |
Adversary (comics) | The Adversary is a fictional character, a demonic supervillain appearing in American comic books published by Marvel Comics. |
APMonitor | Advanced process monitor (APMonitor) is a modeling language for differential algebraic (DAE) equations. It is a free web-service or local server for solving representations of physical systems in the form of implicit DAE models. APMonitor is suited for large-scale problems and solves linear programming, integer programming, nonlinear programming, nonlinear mixed integer programming, dynamic simulation, moving horizon estimation, and nonlinear model predictive control. APMonitor does not solve the problems directly, but calls nonlinear programming solvers such as APOPT, BPOPT, IPOPT, MINOS, and SNOPT. The APMonitor API provides exact first and second derivatives of continuous functions to the solvers through automatic differentiation and in sparse matrix form. |
Tetrahydroharman | Tetrahydroharman(e), also known as 1-methyl-1,2,3,4-tetrahydro-β-carboline, is a general name for one of two isomers: (1S)-1-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole Calligonine ((1R)-1-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole)Calligonine is a major alkaloid constituent of the roots of Calligonum minimum and the bark of Elaeagnus angustifolia. When taken internally, it has the effect of substantially lowering blood pressure for an extended period of time, similar to reserpine. |
Yoke (aeronautics) | A yoke, alternatively known as a control wheel or a control column, is a device used for piloting some fixed-wing aircraft.The pilot uses the yoke to control the attitude of the plane, usually in both pitch and roll. Rotating the control wheel controls the ailerons and the roll axis. Fore and aft movement of the control column controls the elevator and the pitch axis. When the yoke is pulled back, the nose of the aircraft rises. When the yoke is pushed forward, the nose is lowered. When the yoke is turned left, the plane rolls to the left, and when it is turned to the right, the plane rolls to the right. |
XL-413 | XL-413 is a drug which acts as a selective inhibitor of the enzyme cell division cycle 7-related protein kinase (CDC7). It is being researched for the treatment of some forms of cancer, and also has applications in genetic engineering. |
Superfluidity | Superfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without any loss of kinetic energy. When stirred, a superfluid forms vortices that continue to rotate indefinitely. Superfluidity occurs in two isotopes of helium (helium-3 and helium-4) when they are liquefied by cooling to cryogenic temperatures. It is also a property of various other exotic states of matter theorized to exist in astrophysics, high-energy physics, and theories of quantum gravity. The theory of superfluidity was developed by Soviet theoretical physicists Lev Landau and Isaak Khalatnikov. |
