Chromatin structure remodeling (RSC) complex | RSC (Remodeling the Structure of Chromatin) is a member of the ATP-dependent chromatin remodeler family. The activity of the RSC complex allows for chromatin to be remodeled by altering the structure of the nucleosome.There are four subfamilies of chromatin remodelers: SWI/SNF, INO80, ISW1, and CHD. The RSC complex is a 15-subunit chromatin remodeling complex initially found in Saccharomyces cerevisiae, and is homologous to the SWI/SNF complex found in humans. The RSC complex has ATPase activity in the presence of DNA. |
Encoignure | Encoignure is a type of furniture located in a corner of a room. In French, it literally means the angle, or return, formed by the junction of two walls. Since the 20th century, the word has been chiefly used to designate a small armoire, oakley, commode, cabinet, or cupboard made to fit a corner. A chair placed in a corner is referred to as a chaise encoignure.Originally the design came from France, hence the name: pieces in the Louis Quinze or Louis Seize style in lacquer or in mahogany, elaborately mounted in gilded bronze, are among the more alluring pieces from the period of grand French furniture. They were made in a vast variety of forms so far as the front was concerned; but are otherwise strictly limited by their destination. As a rule these delicate and dainty pieces were in pairs and placed in opposite angles; frequently the tops were finished in expensive colored marble. |
Trandolapril | Trandolapril is an ACE inhibitor used to treat high blood pressure. It may also be used to treat other conditions. It is similar in structure to another ACE Inhibitor, Ramipril but has a cyclohexane group. It also is a pro-drug and must get metabolized. It has a longer half-life when compared to other agents in this class.
It was patented in 1981, and approved for medical use in 1993. It is marketed by Abbott Laboratories under the brand name Mavik. |
Geodesic | In geometry, a geodesic () is a curve representing in some sense the shortest path (arc) between two points in a surface, or more generally in a Riemannian manifold. The term also has meaning in any differentiable manifold with a connection. It is a generalization of the notion of a "straight line". |
The Fresh Vegetable Mystery | The Fresh Vegetable Mystery is a 1939 Color Classics cartoon. It was released on September 29, 1939. |
Straw hat | A straw hat is a wide-brimmed hat woven out of straw or straw-like synthetic materials. Straw hats are a type of sun hat designed to shade the head and face from direct sunlight, but are also used in fashion as a decorative element or a uniform. |
Transpiration stream | In plants, the transpiration stream is the uninterrupted stream of water and solutes which is taken up by the roots and transported via the xylem to the leaves where it evaporates into the air/apoplast-interface of the substomatal cavity. It is driven by capillary action and in some plants by root pressure. The main driving factor is the difference in water potential between the soil and the substomatal cavity caused by transpiration. |
PelicanHPC | PelicanHPC is an operating system based on Debian Live, which provides a rapid means of setting up a high performance computer cluster.PelicanHPC was formerly known as ParallelKNOPPIX. |
Hazardous energy | Hazardous energy in occupational safety and health is any source of energy (including electrical, mechanical, thermal, chemical, hydraulic, and pneumatic sources of energy) that "can be hazardous to workers", such as from discharge of stored energy. Failure to control the unexpected release of energy can lead to machine-related injuries or fatalities. The risk from these sources of energy can be controlled in a number of ways, including access control procedures such as lockout-tagout. |

Snaith's theorem | In algebraic topology, a branch of mathematics, Snaith's theorem, introduced by Victor Snaith, identifies the complex K-theory spectrum with the localization of the suspension spectrum of CP∞ away from the Bott element. |
HD 107148 b | HD 107148 b is a jovian exoplanet with minimum mass of only 70% that of Saturn. Unlike Saturn, it orbits much closer to the star. The planetary orbit was significantly refined in the 2021. |
Shark cage diving | Shark cage diving is underwater diving or snorkeling where the observer remains inside a protective cage designed to prevent sharks from making contact with the divers. Shark cage diving is used for scientific observation, underwater cinematography, and as a tourist activity. Sharks may be attracted to the vicinity of the cage by the use of bait, in a procedure known as chumming, which has attracted some controversy as it is claimed to potentially alter the natural behaviour of sharks in the vicinity of swimmers. |
AMD FireMV | AMD FireMV, formerly ATI FireMV, is brand name for graphics cards marketed as a Multi-Display 2D video card, with 3D capabilities same as the low-end Radeon graphics products. It competes directly with Matrox professional video cards. FireMV cards aims at the corporate environment who require several displays attached to a single computer. FireMV cards has options of dual GPU, a total of four display output via a VHDCI connector, or single GPU, a total of two display output via a DMS-59 connector. |
KCNC2 | Potassium voltage-gated channel subfamily C member 2 is a protein that in humans is encoded by the KCNC2 gene. The protein encoded by this gene is a voltage-gated potassium channel subunit (Kv3.2). |
OpenBinder | OpenBinder is a system for inter-process communication. It was developed at Be Inc. and then Palm, Inc. and was the basis for the Binder framework now used in the Android operating system developed by Google.OpenBinder allows processes to present interfaces which may be called by other threads. Each process maintains a thread pool which may be used to service such requests. OpenBinder takes care of reference counting, recursion back into the original thread, and the inter-process communication itself. On the Linux version of OpenBinder, the communication is achieved using ioctls on a given file descriptor, communicating with a kernel driver. |
Büchner–Curtius–Schlotterbeck reaction | The Buchner–Curtius–Schlotterbeck reaction is the reaction of aldehydes or ketones with aliphatic diazoalkanes to form homologated ketones. It was first described by Eduard Buchner and Theodor Curtius in 1885 and later by Fritz Schlotterbeck in 1907. Two German chemists also preceded Schlotterbeck in discovery of the reaction, Hans von Pechmann in 1895 and Viktor Meyer in 1905. The reaction has since been extended to the synthesis of β-keto esters from the condensation between aldehydes and diazo esters. The general reaction scheme is as follows: The reaction yields two possible carbonyl compounds (I and II) along with an epoxide (III). The ratio of the products is determined by the reactant used and the reaction conditions. |
P2PRIV | Peer-to-peer direct and anonymous distribution overlay (P2PRIV) was a conceptual anonymous peer-to-peer overlay network introduced at Warsaw University of Technology in 2007. P2PRIV hides an initiator of communications by a parallelization of network nodes receiving or sending user data independently. This concept is contrary to other anonymity networks topologies. The anonymity networks employ a serial communication as a common basis and hide the initiator in a cascade of network nodes forwarding user data consecutively. The main advantage of P2PRIV is viewed as a possibility of providing high-speed anonymous data transfer while anonymous data can be sent directly and independently in the distributed network. |
Ventral tegmental area | The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain. The VTA is the origin of the dopaminergic cell bodies of the mesocorticolimbic dopamine system and other dopamine pathways; it is widely implicated in the drug and natural reward circuitry of the brain. The VTA plays an important role in a number of processes, including reward cognition (motivational salience, associative learning, and positively-valenced emotions) and orgasm, among others, as well as several psychiatric disorders. Neurons in the VTA project to numerous areas of the brain, ranging from the prefrontal cortex to the caudal brainstem and several regions in between. |
DCTP diphosphatase | In enzymology, a dCTP diphosphatase (EC 3.6.1.12) is an enzyme that catalyzes the chemical reaction dCTP + H2O ⇌ dCMP + diphosphateThus, the two substrates of this enzyme are dCTP and H2O, whereas its two products are dCMP and diphosphate.
This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides in phosphorus-containing anhydrides. The systematic name of this enzyme class is dCTP nucleotidohydrolase. Other names in common use include deoxycytidine-triphosphatase, dCTPase, dCTP pyrophosphatase, deoxycytidine triphosphatase, deoxy-CTPase, and dCTPase. This enzyme participates in pyrimidine metabolism. |
Dress boot | Dress boots are short leather boots typically worn by men. Built like dress shoes, but with uppers covering the ankle, versions of the boots are used as an alternative to these in bad weather or rough outdoor situation, and as a traditional option for day time formalwear. |
DDoS mitigation | DDoS mitigation is a set of network management techniques and/or tools, for resisting or mitigating the impact of distributed denial-of-service (DDoS) attacks on networks attached to the Internet, by protecting the target, and relay networks. DDoS attacks are a constant threat to businesses and organizations, by delaying service performance, or by shutting down a website entirely.DDoS mitigation works by identifying baseline conditions for network traffic by analyzing "traffic patterns", to allow threat detection and alerting. DDoS mitigation also requires identifying incoming traffic, to separate human traffic from human-like bots and hijacked web browsers. This process involves comparing signatures and examining different attributes of the traffic, including IP addresses, cookie variations, HTTP headers, and JavaScript fingerprints. |
Dept. of Computer Science, University of Delhi | The Department of Computer Science, University of Delhi is a department in the University of Delhi under the Faculty of Mathematical Science, set up in 1981. |
Torque tube | A torque tube system is a power transmission and braking technology that involves a stationary housing around the drive shaft, often used in automobiles with a front engine and rear drive. The torque tube consists of a large diameter stationary housing between the transmission and rear end that fully encloses a rotating tubular steel or small-diameter solid drive shaft (known colloquially in the U.S. as a "rope drive") that transmits the power of the engine to a regular or limited-slip differential. The purpose of a torque tube is to hold the rear end in place during acceleration and braking. Otherwise, the axle housing would suffer axle wrap, such that the front of the differential would lift up excessively during acceleration and sink down during braking. Its use is not as widespread in modern automobiles as is the Hotchkiss drive, which holds the rear end in place and prevents it from flipping up or down, during acceleration and braking, by anchoring the axle housings to the leaf springs using spring perches. |
Connective tissue nevus | A connective tissue nevus is a skin lesion which may be present at birth or appear within the first few years of life. It is elevated, soft to firm in consistency, varying in size from 0.5 to several centimeters in diameter, and may manifest as grouped, linear, or irregularly-distributed lesions.: 993 |

1,1'-Dilithioferrocene | 1,1'-Dilithioferrocene is the organoiron compound with the formula Fe(C5H4Li)2. It is exclusively generated and isolated as a solvate, using either ether or tertiary amine ligands bound to the lithium centers. Regardless of the solvate, dilithioferrocene is used commonly to prepare derivatives of ferrocene. |
DK'Tronics | DK'Tronics Ltd (stylised as dk'tronics) was a British software and hardware company active during the 1980s. It primarily made peripherals for the ZX Spectrum and Amstrad CPC but also released video games for the ZX81, ZX Spectrum, Commodore 64, VIC-20, BBC Micro, Memotech MTX, MSX and Amstrad platforms. |
Research balloon | Research balloons are balloons that are used for scientific research. They are usually unmanned, filled with a lighter-than-air gas like helium, and fly at high altitudes.
Meteorology, atmospheric research, astronomy, and military research may be conducted from a research balloon.
Weather balloons are a type of research balloon. Research balloons usually study a single aspect of science, such as air pollution, air temperature, or wind currents, although sometimes several experiments or equipment are flown together. |
Dewcell | Dewcells, dewcels or dew cell are instruments used for determining the dew point. They consist of a small heating element surrounded by a solution of lithium chloride. As the LiCl absorbs moisture from the air, conduction across the heating element increases, current in it increases, and heat increases, evaporating moisture from the salt solution. At a certain temperature the amount of moisture absorbed by the salt solution equals the amount evaporated (equilibrium). |
Tracing (software) | In software engineering, tracing involves a specialized use of logging to record information about a program's execution. This information is typically used by programmers for debugging purposes, and additionally, depending on the type and detail of information contained in a trace log, by experienced system administrators or technical-support personnel and by software monitoring tools to diagnose common problems with software. Tracing is a cross-cutting concern. |
Fundamentals of Physics | Fundamentals of Physics is a calculus-based physics textbook by David Halliday, Robert Resnick, and Jearl Walker. The textbook is currently in its 12th edition (published October, 2021). The current version is a revised version of the original 1960 textbook Physics for Students of Science and Engineering by Halliday and Resnick, which was published in two parts (Part I containing Chapters 1-25 and covering mechanics and thermodynamics; Part II containing Chapters 26-48 and covering electromagnetism, optics, and introducing quantum physics). A 1966 revision of the first edition of Part I changed the title of the textbook to Physics.It is widely used in colleges as part of the undergraduate physics courses, and has been well known to science and engineering students for decades as "the gold standard" of freshman-level physics texts. In 2002, the American Physical Society named the work the most outstanding introductory physics text of the 20th century. |
Hand acupuncture | Koryo hand acupuncture is a modern system of acupuncture, created by Yu Tae-u in the 1970s, in which the hand represents the entire body and is needled or stimulated during treatment. Koryo hand acupuncture is popular among the general population as a form of self-medication in Korea, and has adherents in Japan and North America; it is also popular among overseas Koreans. Korean hand acupuncture is different from American hand reflexology, another form of alternative medicine. One of the main differences between the two forms of alternative therapies is that they each use a different hand microsystem, which is the idea that specific areas of the hand correspond to specific areas of the body. Korean hand acupuncturists believe the entire body can be mapped on each hand, whereas their Western counterparts believe each hand represents only one side of the body. |
LayerWalker | LayerWalker Technology, Inc. is a fabless integrated circuit design company that announced a network storage system on a chip (SoC). Their products targeted digital home, small business and consumer electronics markets.
LayerWalker introduced in 2007 the miniSAN product that provided ATA over Ethernet (AoE) server functions and management capabilities. Client software and drivers for Windows and Linux operating systems were offered.LayerWalker had offices in Taipei. It was founded in 2005 and had a web site through 2012. |
Feces | Feces (or faeces; SG: faex) are the solid or semi-solid remains of food that was not digested in the small intestine, and has been broken down by bacteria in the large intestine. Feces contain a relatively small amount of metabolic waste products such as bacterially altered bilirubin, and dead epithelial cells from the lining of the gut.Feces are discharged through the anus or cloaca during defecation. |
Latent Dirichlet allocation | In natural language processing, Latent Dirichlet Allocation (LDA) is a Bayesian network (and, therefore, a generative statistical model) that explains a set of observations through unobserved groups, and each group explains why some parts of the data are similar. The LDA is an example of a Bayesian topic model. In this, observations (e.g., words) are collected into documents, and each word's presence is attributable to one of the document's topics. Each document will contain a small number of topics. |
Rotational correlation time | Rotational correlation time ( τc ) is the average time it takes for a molecule to rotate one radian. In solution, rotational correlation times are in the order of picoseconds. For example, the τc= 1.7 ps for water, and 100 ps for a pyrroline nitroxyl radical in a DMSO-water mixture. Rotational correlation times are employed in the measurement of microviscosity (viscosity at the molecular level) and in protein characterization. |
CIMOSA | CIMOSA, standing for "Computer Integrated Manufacturing Open System Architecture", is an enterprise modeling framework, which aims to support the enterprise integration of machines, computers and people. The framework is based on the system life cycle concept, and offers a modelling language, methodology and supporting technology to support these goals.It was developed in the 1990s by the AMICE Consortium, in an EU project. A non-profit organization CIMOSA Association was later established to keep ownership of the CIMOSA specification, to promote it and to support its further evolution. |
Orders of magnitude (illuminance) | As visual perception varies logarithmically, it is helpful to have an appreciation of both illuminance and luminance by orders of magnitude. |
12-O-Tetradecanoylphorbol-13-acetate | 12-O-Tetradecanoylphorbol-13-acetate (TPA), also commonly known as tetradecanoylphorbol acetate, tetradecanoyl phorbol acetate, and phorbol 12-myristate 13-acetate (PMA) is a diester of phorbol. It is a potent tumor promoter often employed in biomedical research to activate the signal transduction enzyme protein kinase C (PKC). The effects of TPA on PKC result from its similarity to one of the natural activators of classic PKC isoforms, diacylglycerol. TPA is a small molecule drug. |
RAL colour standard | RAL is a colour management system used in Europe that is created and administrated by the German RAL gGmbH (RAL non-profit LLC), which is a subsidiary of the German RAL Institute. In colloquial speech, RAL refers to the RAL Classic system, mainly used for varnish and powder coating, but now plastics as well. Approved RAL products are provided with a hologram to make unauthorised versions difficult to produce. Imitations may show different hue and colour when observed under various light sources. |
Look Nevada | Look's Nevada, released in 1950, was the first recognizably modern alpine ski binding. The Nevada was only the toe portion of the binding, and was used with a conventional cable binding for the heel. An updated version was introduced in 1962 with a new step-in heel binding, the Grand Prix. These basic mechanisms formed the basis for LOOK bindings for over 40 years, changing mainly in name and construction materials. The Nevada toe pattern is almost universal among bindings today. |
Herbig Ae/Be star | A Herbig Ae/Be star (HAeBe) is a pre-main-sequence star – a young (<10 Myr) star of spectral types A or B. These stars are still embedded in gas-dust envelopes and are sometimes accompanied by circumstellar disks. Hydrogen and calcium emission lines are observed in their spectra. They are 2-8 Solar mass (M☉) objects, still existing in the star formation (gravitational contraction) stage and approaching the main sequence (i.e. they are not burning hydrogen in their center). |
Lithuanian Braille | Lithuanian Braille is the braille alphabet of the Lithuanian language. |
Telly (home entertainment server) | The Telly home entertainment server is range of computer systems designed to store, manage, and access all forms of digital media in the home. Based on Interact-TV's Linux Media Center software, it provides user managed libraries for music, photos, and all forms of video from recorded television programming to DVDs. |
Private library | Private libraries are libraries that are privately owned and are usually intended for the use of a small number of people, or even a single person. As with public libraries, some people use bookplates – stamps, stickers or embossing – to show ownership of the items. Some people sell their private libraries to established institutions such as the Library of Congress, or, as is often the case, bequeath them after death. Much less often, a private library is maintained intact long after the death of the owner. |
Marvel Cinematic Universe tie-in comics | The Marvel Cinematic Universe tie-in comic books are limited series or one-shot comics published by Marvel Comics that tie into the films and television series of the Marvel Cinematic Universe (MCU). The comics are written and illustrated by a variety of individuals, and each one consists of 1 to 4 issues. They are intended to tell additional stories about existing characters, or to make connections between MCU projects, without necessarily expanding the universe or introducing new concepts or characters. |
Paver (vehicle) | A paver (road paver finisher, asphalt finisher, road paving machine) is a piece of construction equipment used to lay asphalt concrete or Portland cement concrete on roads, bridges, parking lots and other such places. It lays the material flat and provides minor compaction. This is typically followed by final compaction by a road roller. |
Great disdyakis dodecahedron | In geometry, the great disdyakis dodecahedron is a nonconvex isohedral polyhedron. It is the dual of the uniform great truncated cuboctahedron. It has 48 triangular faces. |
Valnemulin | Valnemulin (trade name Econor or Biotilina) is a pleuromutilin antibiotic used to treat swine dysentery, ileitis, colitis and pneumonia. It is also used for the prevention of intestinal infections of swine. Valnemulin has been observed to induce a rapid reduction of clinical symptoms of Mycoplasma bovis infection, and eliminate M. bovis from the lungs of calves. |
MicroRNA 548f-4 | MicroRNA 548f-4 is a protein that in humans is encoded by the MIR548F4 gene. |
Hidden states of matter | A hidden state of matter is a state of matter which cannot be reached under ergodic conditions, and is therefore distinct from known thermodynamic phases of the material. Examples exist in condensed matter systems, and are typically reached by the non-ergodic conditions created through laser photo excitation. Short-lived hidden states of matter have also been reported in crystals using lasers. Recently a persistent hidden state was discovered in a crystal of Tantalum(IV) sulfide (TaS2), where the state is stable at low temperatures. A hidden state of matter is not to be confused with hidden order, which exists in equilibrium, but is not immediately apparent or easily observed. |
Forward premium anomaly | The forward premium anomaly in currency markets (also referred to as the forward premium puzzle or the Fama puzzle) refers to the well documented empirical finding that the domestic currency appreciates when domestic nominal interest rates exceed foreign interest rates. This is perceived as puzzling in the context of the hypothesis that the expected future change in the exchange rate between two countries is equal to the interest-rate differential between these two countries; this hypothesis suggests that if all currencies are equally risky, investors would demand higher interest rates on currencies expected to fall in value. See: Forward exchange rate# Unbiasedness hypothesis. Thus, appreciation of the domestic currency when domestic interest rates are greater than foreign interest rates is called an anomaly. |
Dihydrodeoxycorticosterone | 5α-Dihydrodeoxycorticosterone (abbreviated as DHDOC), also known as 21-hydroxy-5α-pregnan-20-one, is an endogenous progestogen and neurosteroid. It is synthesized from the adrenal hormone deoxycorticosterone (DOC) by the enzyme 5α-reductase type I. DHDOC is an agonist of the progesterone receptor, as well as a positive allosteric modulator of the GABAA receptor, and is known to have anticonvulsant effects. |
Metatarsophalangeal joints | The metatarsophalangeal joints (MTP joints), also informally known as toe knuckles, are the joints between the metatarsal bones of the foot and the proximal bones (proximal phalanges) of the toes. They are condyloid joints, meaning that an elliptical or rounded surface (of the metatarsal bones) comes close to a shallow cavity (of the proximal phalanges).
The ligaments are the plantar and two collateral. |
Kraft process | The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibres, the main component of paper. The kraft process involves treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na2S), known as white liquor, that breaks the bonds that link lignin, hemicellulose, and cellulose. The technology entails several steps, both mechanical and chemical. It is the dominant method for producing paper. In some situations, the process has been controversial because kraft plants can release odorous products and in some situations produce substantial liquid wastes.The process name is derived from German word Kraft, meaning "strength" in this context, due to the strength of the kraft paper produced using this process. |
Enhanced Variable Rate Codec | Enhanced Variable Rate CODEC (EVRC) is a speech codec used in CDMA networks. It was developed in 1995 to replace the QCELP vocoder which used more bandwidth on the carrier's network, thus EVRC's primary goal was to offer the mobile carriers more capacity on their networks while not increasing the amount of bandwidth or wireless spectrum needed. EVRC uses RCELP technology. |
Internet industry jargon | Internet industry jargon is a unique way of speaking used by people working in the internet industry. It shows how those people talk and communicate with each other in their work setting and can vary with different language cultures in different countries. The jargon consists of familiar words found in daily life, but combined and used in the internet industry to create new concepts that describe and express specific ideas. Those jargons are intensively used in their speaking. It is often hard for people outside of this industry to understand what they are talking about although every word seems familiar. |
Baer ring | In abstract algebra and functional analysis, Baer rings, Baer *-rings, Rickart rings, Rickart *-rings, and AW*-algebras are various attempts to give an algebraic analogue of von Neumann algebras, using axioms about annihilators of various sets.
Any von Neumann algebra is a Baer *-ring, and much of the theory of projections in von Neumann algebras can be extended to all Baer *-rings, For example, Baer *-rings can be divided into types I, II, and III in the same way as von Neumann algebras.
In the literature, left Rickart rings have also been termed left PP-rings. ("Principal implies projective": See definitions below.) |
Interactive planning | Interactive planning is a concept developed by Russell L. Ackoff, an American theorist, early proponent of the field of operations research and recognized as the pioneer in systems thinking. Interactive planning forwards the idea that in order to arrive at a desirable future, one has to create a desirable present and create ways and means to resemble it. One of its unique features is that development should be ideal-oriented. Interactive planning is unlike other types of planning such as reactive planning, inactive planning, and preactive planning. |
Opticin | Opticin is a protein that in humans is encoded by the OPTC gene.Opticin belongs to class III of the small leucine-rich repeat protein (SLRP) family. Members of this family are typically associated with the extracellular matrix. Opticin is present in significant quantities in the vitreous of the eye and also localizes to the cornea, iris, ciliary body, optic nerve, choroid, retina, and fetal liver. Opticin may noncovalently bind collagen fibrils and regulate fibril morphology, spacing, and organization. The opticin gene is mapped to a region of chromosome 1 that is associated with the inherited eye diseases age-related macular degeneration (AMD) and posterior column ataxia with retinosa pigmentosa (AXPC1). |
Apple Inc. v. Samsung Electronics Co. | Apple Inc. v. Samsung Electronics Co., Ltd. was the first of a series of ongoing lawsuits between Apple Inc. and Samsung Electronics regarding the design of smartphones and tablet computers; between them, the companies made more than half of smartphones sold worldwide as of July 2012. In the spring of 2011, Apple began litigating against Samsung in patent infringement suits, while Apple and Motorola Mobility were already engaged in a patent war on several fronts. Apple's multinational litigation over technology patents became known as part of the mobile device "smartphone patent wars": extensive litigation in fierce competition in the global market for consumer mobile communications. By August 2011, Apple and Samsung were litigating 19 ongoing cases in nine countries; by October, the legal disputes expanded to ten countries. By July 2012, the two companies were still embroiled in more than 50 lawsuits around the globe, with billions of dollars in damages claimed between them. While Apple won a ruling in its favor in the U.S., Samsung won rulings in South Korea, Japan, and the UK. On June 4, 2013, Samsung won a limited ban from the U.S. International Trade Commission on sales of certain Apple products after the commission found Apple had violated a Samsung patent, but this was vetoed by U.S. Trade Representative Michael Froman.On December 6, 2016, the United States Supreme Court decided 8–0 to reverse the decision from the first trial that awarded nearly $400 million to Apple and returned the case to Federal Circuit court to define the appropriate legal standard "article of manufacture" because it is not the smartphone itself but could be just the case and screen to which the design patents relate. |
Ankle replacement | Ankle replacement, or ankle arthroplasty, is a surgical procedure to replace the damaged articular surfaces of the human ankle joint with prosthetic components. This procedure is becoming the treatment of choice for patients requiring arthroplasty, replacing the conventional use of arthrodesis, i.e. fusion of the bones. The restoration of range of motion is the key feature in favor of ankle replacement with respect to arthrodesis. However, clinical evidence of the superiority of the former has only been demonstrated for particular isolated implant designs. |
Division lattice | The division lattice is an infinite complete bounded distributive lattice whose elements are the natural numbers ordered by divisibility. Its least element is 1, which divides all natural numbers, while its greatest element is 0, which is divisible by all natural numbers. The meet operation is greatest common divisor while the join operation is least common multiple.
The prime numbers are precisely the atoms of the division lattice, namely those natural numbers divisible only by themselves and 1. |
OR10AG1 | Olfactory receptor 10AG1 is a protein that in humans is encoded by the OR10AG1 gene.Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. The nomenclature assigned to the olfactory receptor genes and proteins for this organism is independent of other organisms. |
Opacity (optics) | Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and scattering of radiation in a medium, such as a plasma, dielectric, shielding material, glass, etc. An opaque object is neither transparent (allowing all light to pass through) nor translucent (allowing some light to pass through). When light strikes an interface between two substances, in general some may be reflected, some absorbed, some scattered, and the rest transmitted (also see refraction). Reflection can be diffuse, for example light reflecting off a white wall, or specular, for example light reflecting off a mirror. An opaque substance transmits no light, and therefore reflects, scatters, or absorbs all of it. Other categories of visual appearance, related to the perception of regular or diffuse reflection and transmission of light, have been organized under the concept of cesia in an order system with three variables, including opacity, transparency and translucency among the involved aspects. Both mirrors and carbon black are opaque. Opacity depends on the frequency of the light being considered. For instance, some kinds of glass, while transparent in the visual range, are largely opaque to ultraviolet light. More extreme frequency-dependence is visible in the absorption lines of cold gases. Opacity can be quantified in many ways; for example, see the article mathematical descriptions of opacity. |
Classical Nahuatl grammar | The grammar of Classical Nahuatl is agglutinative, head-marking, and makes extensive use of compounding, noun incorporation and derivation. That is, it can add many different prefixes and suffixes to a root until very long words are formed. Very long verbal forms or nouns created by incorporation, and accumulation of prefixes are common in literary works. New words can thus be easily created. |
Aluminide | An aluminide is a compound that has aluminium with more electropositive elements. Since aluminium is near the nonmetals on the periodic table, it can bond with metals differently from other metals. The properties of an aluminide are between those of a metal alloy and those of an ionic compound. |
Code page 950 | Code page 950 is the code page used on Microsoft Windows for Traditional Chinese. It is Microsoft's implementation of the de facto standard Big5 character encoding. The code page is not registered with IANA, and hence, it is not a standard to communicate information over the internet, although it is usually labelled simply as big5, including by Microsoft library functions. |
Dimorphic root system | A dimorphic root system is a plant root system with two distinct root forms, which are adapted to perform different functions. One of the most common manifestations is in plants with both a taproot, which grows straight down to the water table, from which it obtains water for the plant; and a system of lateral roots, which obtain nutrients from superficial soil layers near the surface. Many plants with dimorphic root systems adapt the levels of rainfall in the surrounding area, growing many surface roots when there is heavy rainfall, and relying on a taproot when rain is scarce. Because of their adaptability to water levels in the surrounding area, most plants with dimorphic root systems live in arid climates with common wet and dry periods. |
Ingleton's inequality | In mathematics, Ingleton's inequality is an inequality that is satisfied by the rank function of any representable matroid. In this sense it is a necessary condition for representability of a matroid over a finite field. Let M be a matroid and let ρ be its rank function, Ingleton's inequality states that for any subsets X1, X2, X3 and X4 in the support of M, the inequality ρ(X1)+ρ(X2)+ρ(X1∪X2∪X3)+ρ(X1∪X2∪X4)+ρ(X3∪X4) ≤ ρ(X1∪X2)+ρ(X1∪X3)+ρ(X1∪X4)+ρ(X2∪X3)+ρ(X2∪X4) is satisfied.Aubrey William Ingleton, an English mathematician, wrote an important paper in 1969 in which he surveyed the representability problem in matroids. Although the article is mainly expository, in this paper Ingleton stated and proved Ingleton's inequality, which has found interesting applications in information theory, matroid theory, and network coding. |
SnackWell effect | The SnackWell effect is a phenomenon whereby dieters will eat more low-calorie cookies, such as SnackWells, than they otherwise would for normal cookies. Also known as moral license, it is also described as a term for the way people go overboard once they are given a free pass or the tendency of people to overconsume when eating more of low-fat food due to the belief that it is not fattening.The term, which emerged as a reaction to dietary trends in the 1980s and 1990s, is also used for similar effects in other settings, such as energy consumption, where it is termed the "rebound effect". For example, according to a 2008 study, people with energy-efficient washing machines wash more clothes. People with energy-efficient lights leave them on longer, and lose 5–12% of the expected energy savings of 80%. |
JSON streaming | JSON streaming comprises communications protocols to delimit JSON objects built upon lower-level stream-oriented protocols (such as TCP), that ensures individual JSON objects are recognized, when the server and clients use the same one (e.g. implicitly coded in). This is necessary as JSON is a non-concatenative protocol (the concatenation of two JSON objects does not produce a valid JSON object). |
Time-lapse microscopy | Time-lapse microscopy is time-lapse photography applied to microscopy.
Microscope image sequences are recorded and then viewed at a greater speed to give an accelerated view of the microscopic process.
Before the introduction of the video tape recorder in the 1960s, time-lapse microscopy recordings were made on photographic film.
During this period, time-lapse microscopy was referred to as microcinematography.
With the increasing use of video recorders, the term time-lapse video microscopy was gradually adopted.
Today, the term video is increasingly dropped, reflecting that a digital still camera is used to record the individual image frames, instead of a video recorder. |
Style sheet (desktop publishing) | A style sheet is a feature in desktop publishing programs that store and apply formatting to text. Style sheets are a form of separation of presentation and content: it creates a separate abstraction to keep the presentation isolated from the text data.
Style sheets are a common feature in most popular desktop publishing and word processing programs, including Corel Ventura, Adobe InDesign, Scribus, PageMaker, QuarkXPress, WordPerfect, and Microsoft Word, though they may be referred to using slightly different terminology. |
Federer–Morse theorem | In mathematics, the Federer–Morse theorem, introduced by Federer and Morse (1943), states that if f is a surjective continuous map from a compact metric space X to a compact metric space Y, then there is a Borel subset Z of X such that f restricted to Z is a bijection from Z to Y.
Moreover, the inverse of that restriction is a Borel section of f—it is a Borel isomorphism. |
Dublin Core | The Dublin Core, also known as the Dublin Core Metadata Element Set (DCMES), is a set of fifteen main metadata items for describing digital or physical resources. The Dublin Core Metadata Initiative (DCMI) is responsible for formulating the Dublin Core; DCMI is a project of the Association for Information Science and Technology (ASIS&T), a non-profit organization. Dublin Core has been formally standardized internationally as ISO 15836 by the International Organization for Standardization (ISO) and as IETF RFC 5013 by the Internet Engineering Task Force (IETF), as well as in the U.S. as ANSI/NISO Z39.85 by the National Information Standards Organization (NISO).The core properties are part of a larger set of DCMI Metadata Terms. "Dublin Core" is also used as an adjective for Dublin Core metadata, a style of metadata that draws on multiple Resource Description Framework (RDF) vocabularies, packaged and constrained in Dublin Core application profiles.The resources described using the Dublin Core may be digital resources (video, images, web pages, etc.) as well as physical resources such as books or works of art. |
Interlock protocol | In cryptography, the interlock protocol, as described by Ron Rivest and Adi Shamir, is a protocol designed to frustrate eavesdropper attack against two parties that use an anonymous key exchange protocol to secure their conversation. A further paper proposed using it as an authentication protocol, which was subsequently broken. |
Dual systems model | The dual systems model, also known as the maturational imbalance model, is a theory arising from developmental cognitive neuroscience which posits that increased risk-taking during adolescence is a result of a combination of heightened reward sensitivity and immature impulse control. In other words, the appreciation for the benefits arising from the success of an endeavor is heightened, but the appreciation of the risks of failure lags behind. |
Anytime algorithm | In computer science, an anytime algorithm is an algorithm that can return a valid solution to a problem even if it is interrupted before it ends. The algorithm is expected to find better and better solutions the longer it keeps running. |

Glycoside hydrolase family 101 | In molecular biology, glycoside hydrolase family 101 is a family of glycoside hydrolases. |
Reperfusion injury | Reperfusion injury, sometimes called ischemia-reperfusion injury (IRI) or reoxygenation injury, is the tissue damage caused when blood supply returns to tissue (re- + perfusion) after a period of ischemia or lack of oxygen (anoxia or hypoxia). The absence of oxygen and nutrients from blood during the ischemic period creates a condition in which the restoration of circulation results in inflammation and oxidative damage through the induction of oxidative stress rather than (or along with) restoration of normal function. |
SWIM Protocol | The Scalable Weakly Consistent Infection-style Process Group Membership (SWIM) Protocol is a group membership protocol based on "outsourced heartbeats" used in distributed systems, first introduced by Indranil Gupta in 2001. It is a hybrid algorithm which combines failure detection with group membership dissemination. |
Esthesiometer | An esthesiometer (British spelling aesthesiometer) is a device for measuring the tactile sensitivity of the skin (or mouth, or eye, etc.). The measure of the degree of tactile sensitivity is called aesthesiometry. The device was invented by Edward Henry Sieveking. There are different types of aesthesiometers depending on their particular function. |
Magnetic seizure therapy | Magnetic seizure therapy (MST) is a proposed form of electrotherapy and electrical brain stimulation. It is currently being investigated for the treatment of major depressive disorder, treatment-resistant depression (TRD), bipolar depression, schizophrenia and obsessive-compulsive disorder. MST is stated to work by inducing seizures via magnetic fields, in contrast to ECT which does so using alternating electric currents. Additionally, MST works in a more concentrated fashion than ECT, thus able to create a seizure with less of a total electric charge. In contrast to (r)TMS, the stimulation rates are higher (e.g. 100 Hz at 2 T) resulting in more energy transfer. Currently it is thought that MST works in patients with major depressive disorder by activating the connection between the subgenual anterior cingulate cortex and the parietal cortex. |
