Neumann series | A Neumann series is a mathematical series of the form ∑k=0∞Tk where T is an operator and := Tk−1∘T its k times repeated application. This generalizes the geometric series.
The series is named after the mathematician Carl Neumann, who used it in 1877 in the context of potential theory. The Neumann series is used in functional analysis. It forms the basis of the Liouville-Neumann series, which is used to solve Fredholm integral equations. It is also important when studying the spectrum of bounded operators. |
Inshes Formation | The Inshes Formation is a geologic formation in Scotland. It preserves fossils dating back to the Devonian period. |
Comparison of lightweight web browsers | A lightweight web browser is a web browser that sacrifices some of the features of a mainstream web browser in order to reduce the consumption of system resources, and especially to minimize the memory footprint.The tables below compare notable lightweight web browsers. Several of them use a common layout engine, but each has a unique combination of features and a potential niche. The minimal user interface in surf, for example, does not have tabs, whereas xombrero can be driven with vi-like keyboard commands.Four of the browsers compared—Lynx, w3m, Links, and ELinks—are designed for text mode, and can function in a terminal emulator. Eww is limited to working within Emacs. Links 2 has both a text-based user interface and a graphical user interface. w3m is, in addition to being a web browser, also a terminal pager. |
Metabolic myopathy | Metabolic myopathies are myopathies that result from defects in biochemical metabolism that primarily affect muscle. They are generally genetic defects that interfere with muscle's ability to create energy, causing a low ATP reservoir within the muscle cell. |

Acronis Secure Zone | Acronis Secure Zone is a hard disk partition type created and used by Acronis True Image as a backup storage target. |
Metalloprotease inhibitor | Metalloprotease inhibitors are cellular inhibitors of the Matrix metalloproteinases (MMPs). MMPs belong to a family of zinc-dependent neutral endopeptidases. These enzymes have the ability to break down connective tissue. The expression of MMPs is increased in various pathological conditions like inflammatory conditions, metabolic bone disease, to cancer invasion, metastasis and angiogenesis. |
Retro screening | Retro (or reverse) screening (RS) is a relatively new approach to determine the specificity and selectivity of a therapeutic drug molecule against a target protein or another macromolecule. It proceeds in the opposite direction to the so-called virtual screening (VS). In VS, the goal is to use a protein target to identify a high-affinity ligand from a search library typically containing hundreds of thousands of small molecules. In contrast, RS employs a known drug molecule to screen a protein library containing hundreds of thousands of individual structures (obtained from both experimental and modeling techniques). Accordingly, the extent to which this drug cross-reacts with the human proteome provides a measure of its efficacy and the potential long-term side-effects. RS is expected to play a key role in providing an additional layer of quality control in drug discovery. |
Public interface | In computer science, a public interface is the logical point at which independent software entities interact. The entities may interact with each other within a single computer, across a network, or across a variety of other topologies.
It is important that public interfaces will be stable and designed to support future changes, enhancements, and deprecation in order for the interaction to continue. |
10-Deacetylbaccatin | 10-Deacetylbaccatins are a series of closely related natural organic compounds isolated from the yew tree (Genera Taxus). 10-Deacetylbaccatin III is a precursor to the anti-cancer drug docetaxel (Taxotere). 10-deacetylbaccatin III 10-O-acetyltransferase converts 10-deacetylbaccatin to baccatin III: acetyl-CoA + 10-deacetylbaccatin III ⇌ CoA + baccatin III |

Jaguar (software) | Jaguar is a computer software package used for ab initio quantum chemistry calculations for both gas and solution phases. It is commercial software marketed by the company Schrödinger. The program was originated in research groups of Richard Friesner and William Goddard and was initially called PS-GVB (referring to the so-called pseudospectral generalized valence bond method that the program featured).
Jaguar is a component of two other Schrödinger products: Maestro, which provides the graphical user interface to Jaguar, and a QM/MM program QSite, which uses Jaguar as its quantum-chemical engine. The current version is Jaguar 10.4 (2020). |

A fluorine (F) anion may partially replace the hydroxyl (OH). |
Outsiders (comics) | The Outsiders are a superhero team appearing in American comic books published by DC Comics. As their name suggests, the team consists of superheroes who do not fit the norms of the "mainstream" superhero community, i.e. the Justice League.The Outsiders have had a number of different incarnations. They were founded by Batman, whose ties to the League had become strained at the time, and introduced the now-classic line-up of Batman, Black Lightning, Metamorpho, Geo-Force, Katana, Halo and Looker. A later incarnation of the Outsiders from the early 2000s comics was led by Nightwing and Arsenal following the dissolution of the Teen Titans superhero group, and depicted the team as a pro-active group hunting for supercriminals. For the team's third incarnation, Batman reforms the team as a special strike team featuring classic members Katana and Metamorpho alongside new recruits such as Catwoman and Black Lightning's daughter Thunder. After the Batman R.I.P. storyline, Alfred Pennyworth acts on Batman's instructions to reassemble the team once more, recruiting new members and more of the team's original lineup.Another version of the team with a familiar line-up briefly featured in Batman Incorporated in 2011 as the black ops section of Batman's organization. Following DC's 2011 reboot, a new version of the Outsiders is introduced in the pages of Green Arrow as a secret society represented by seven weapon-themed clans. Members in this incarnation include Katana, Onyx, and several new characters. The original Outsiders are returned to continuity in 2017, following DC Rebirth, once again as a secret team founded by Batman; Batman revives the team with a new line-up in 2018. Black Lightning leads another incarnation in 2022. |
Queuing delay | In telecommunication and computer engineering, the queuing delay or queueing delay is the time a job waits in a queue until it can be executed. It is a key component of network delay. In a switched network, queuing delay is the time between the completion of signaling by the call originator and the arrival of a ringing signal at the call receiver. Queuing delay may be caused by delays at the originating switch, intermediate switches, or the call receiver servicing switch. In a data network, queuing delay is the sum of the delays between the request for service and the establishment of a circuit to the called data terminal equipment (DTE). In a packet-switched network, queuing delay is the sum of the delays encountered by a packet between the time of insertion into the network and the time of delivery to the address. |
Substances poisonous to dogs | Some substances are poisonous to dogs through ingestion, contact, or inhalation. The poisons' effects can vary from mild illness to death. The poisonous substances most commonly consumed by pet dogs are human foods (including chocolate and grapes), medication not suitable for animals, household products, and plants. |
Simple Bus Architecture | The Simple Bus Architecture (SBA) is a form of computer architecture. It is made up software tools and intellectual property cores (IP Core) interconnected by buses using simple and clear rules, that allow the implementation of an embedded system (SoC). Basic templates are provided to accelerate design. The VHDL code that implements this architecture is portable. |
Parastatistics | In quantum mechanics and statistical mechanics, parastatistics is one of several alternatives to the better known particle statistics models (Bose–Einstein statistics, Fermi–Dirac statistics and Maxwell–Boltzmann statistics). Other alternatives include anyonic statistics and braid statistics, both of these involving lower spacetime dimensions. Herbert S. Green is credited with the creation of parastatistics in 1953. |
Bayley Scales of Infant Development | The Bayley Scales of Infant and Toddler Development (version 4 was released September 2019) is a standard series of measurements originally developed by psychologist Nancy Bayley used primarily to assess the development of infants and toddlers, ages 1–42 months. This measure consists of a series of developmental play tasks and takes between 45 – 60 minutes to administer and derives a developmental quotient (DQ) rather than an intelligence quotient (IQ). Raw scores of successfully completed items are converted to scale scores and to composite scores. These scores are used to determine the child's performance compared with norms taken from typically developing children of their age (in months). The Bayley-III has three main subtests; the Cognitive Scale, which includes items such as attention to familiar and unfamiliar objects, looking for a fallen object, and pretend play, the Language Scale, which taps understanding and expression of language, for example, recognition of objects and people, following directions, and naming objects and pictures, and the Motor Scale, which assesses gross and fine motor skills such as grasping, sitting, stacking blocks, and climbing stairs. There are two additional Bayley-II Scales depend on parental report, including the Social-Emotional scale, which asks caregivers about such behaviors as ease of calming, social responsiveness, and imitation play, and the Adaptive Behavior scale which asks about adaptions to the demands of daily life, including communication, self-control, following rules, and getting along with others. The Bayley-III Cognitive and Language scales are good predictors of preschool mental test performance. These scores are largely used for screening, helping to identify the need for further observation and intervention, as infants who score very low are at risk for future developmental problems. |
ATF4 | Activating transcription factor 4 (tax-responsive enhancer element B67), also known as ATF4, is a protein that in humans is encoded by the ATF4 gene. |
Electroviscous effects | Electroviscous effects, in chemistry of colloids and surface chemistry, according to an IUPAC definition, are the effects of the particle surface charge on viscosity of a fluid. |
Feeder link | A feeder link is – according to Article 1.115 of the International Telecommunication Union´s (ITU) ITU Radio Regulations (RR) – defined as: A radio link from an earth station at a given location to a space station, or vice versa, conveying information for a space radiocommunication service other than for the fixed-satellite service. The given location may be at a specified fixed point, or at any fixed point within specified areas. |
Honor 8x | The Honor 8x is a smartphone made by Huawei under their Honor sub-brand. It is a successor of the Huawei Honor 7x within the Huawei Honor series. |
Design load | In a general sense, the design load is the maximum amount of something a system is designed to handle or the maximum amount of something that the system can produce, which are very different meanings. For example, a crane with a design load of 20 tons is designed to be able to lift loads that weigh 20 tons or less. However, when a failure could be catastrophic, such as a crane dropping its load or collapsing entirely, a factor of safety is necessary. As a result, the crane should lift about 2 to 5 tons at the most. In structural design, a design load is greater than the load which the system is expected to support. This is because engineers incorporate a safety factor in their design, in order to ensure that the system will be able to support at least the expected loads (called specified loads, despite any problems with construction, materials, etc. that go unnoticed during construction. |
Search Party | Search party is a general term referring to a group of people organized to look for someone or something that is lost. It may also refer to: Search Party (album), by ¡Mayday!

Duck and cover | "Duck and cover" is a method of personal protection against the effects of a nuclear explosion. Ducking and covering is useful in offering a degree of protection to personnel located outside the radius of the nuclear fireball but still within sufficient range of the nuclear explosion that standing upright and uncovered is likely to cause serious injury or death. In the most literal interpretation, the focus of the maneuver is primarily on protective actions one can take during the first few crucial seconds-to-minutes after the event, while the film of the same name and a full encompassing of the advice also cater to providing protection up to weeks after the event. |
Nickel(II) iodide | Nickel(II) iodide is an inorganic compound with the formula NiI2. This paramagnetic black solid dissolves readily in water to give bluish-green solutions, from which crystallizes the aquo complex [Ni(H2O)6]I2 (image above). This bluish-green colour is typical of hydrated nickel(II) compounds. Nickel iodides find some applications in homogeneous catalysis. |
Cadmium tetrafluoroborate | Cadmium tetrafluoroborate is an ionic, chemical compound with the formula Cd(BF4)2. It is a crystalline solid, which is colorless and odorless. Cadmium tetrafluoroborate is most frequently used in the industrial production of high-strength steels, its purpose being to prevent hydrogen absorption, a source of post-production cracking of the metal, in the treated steels. Another application of the chemistry of cadmium tetrafluoroborate is fine tuning of the size of cadmium telluride nanomaterials. |
Magnetic Joe | Magnetic Joe is a puzzle-platform game developed for mobile phones by Hungarian studio Most Wanted Entertainment and published by HD publishing in 2006. The objective is to guide a magnetic metal ball, known as Joe, to a designated exit in each level using various magnetic forces. |
Hard flaccid syndrome | Hard flaccid syndrome (HFS), also known as hard flaccid (HF), is a chronic painful condition characterized by a semi-rigid penis at the flaccid state, a soft glans at the erect state, pelvic pain, low libido, erectile dysfunction, erectile pain, pain on ejaculation, penile sensory changes (numbness or coldness), lower urinary tract symptoms, contraction of the pelvic floor muscles, and psychological distress. Other complaints include rectal and perineal discomfort, cold hands and feet, and a hollow or detached feeling inside the penile shaft. The majority of HFS patients are in their 20s–30s and symptoms significantly affect one's quality of life.Sufferers typically report the onset of symptoms after trauma due to a mishap during sexual intercourse or tough masturbation, specifically a traumatic injury at the base of the erect penis, possibly affecting the dorsal artery of the penis, the bulbourethral and the pudendal arteries, as well as the pudendal and dorsal nerve of the penis. Penile sensory and textural changes, as well as changes in appearance, are hallmarks of the condition and serve to distinguish HFS from classic chronic pelvic pain syndrome or BPH.Both biological and psychological influences contribute to the condition by altering the neurovascular supply to the muscles of the pelvic floor and penis. One theory proposes that HFS is a result of an initial stress which triggers an abnormal fight or flight response resulting in increased sympathetic stimulation to the muscles of the pelvis via the perineal branch of the pudendal nerve. In turn, a surge of adrenaline, noradrenaline and cortisol is released from the efferent nerve fibers promoting increased blood flow to the bulbospongiosus, ischiocavernous and levator ani muscles as well as sustained muscle contraction which results in obstructed venous outflow from the penis via compression of the deep dorsal vein and pelvic myoneuropathy secondary to neurogenic inflammation. |
Võ phục | Võ phục (Chữ Hán: 武服) is a Vietnamese term that refers to a martial arts uniform (which may include a ranking belt), mainly associated with Vietnamese martial arts, particularly Vovinam. |
Nonmetal | Nonmetal may refer to: Nonmetal (chemistry), a chemical element with relatively low density and high electronegativity Nonmetal (astrophysics), refers only to the elements hydrogen and helium |
Precision approach radar | Precision approach radar (PAR) is a type of radar guidance system designed to provide lateral and vertical guidance to an aircraft pilot for landing, until the landing threshold is reached. Controllers monitoring the PAR displays observe each aircraft's position and issue instructions to the pilot that keep the aircraft on course and glidepath during final approach. After the aircraft reaches the decision height (DH) or decision altitude (DA), further guidance is advisory only. The overall concept is known as ground-controlled approach (GCA), and this name was also used to refer to the radar systems in the early days of its development. |
Photometric system | In astronomy, a photometric system is a set of well-defined passbands (or optical filters), with a known sensitivity to incident radiation. The sensitivity usually depends on the optical system, detectors and filters used. For each photometric system a set of primary standard stars is provided. |
Item-total correlation | The item-total correlation test arises in psychometrics in contexts where a number of tests or questions are given to an individual and where the problem is to construct a useful single quantity for each individual that can be used to compare that individual with others in a given population. The test is used to see if any of the tests or questions ("items") do not have responses that vary in line with those for other tests across the population. The summary measure would be an average of some form, weighted where necessary, and the item-correlation test is used to decide whether or not responses to a given test should be included in the set being averaged. In some fields of application such a summary measure is called a scale. |
Boccia classification | Boccia classification is the classification system governing boccia, a sport designed specifically for people with disabilities. Classification is handled by Cerebral Palsy International Sports and Recreation Association. There are four classifications for this sport. All four classes are eligible to compete at the Paralympic Games. |
FKM | FKM is a family of fluorocarbon-based fluoroelastomer materials defined by ASTM International standard D1418, and ISO standard 1629. It is commonly called fluorine rubber or fluoro-rubber. FKM is an abbreviation of Fluorine Kautschuk Material. All FKMs contain vinylidene fluoride as a monomer. Originally developed by DuPont (under the brand name Viton, now owned by Chemours), FKMs are today also produced by many companies, including: Daikin (Dai-El), 3M (Dyneon), Solvay S.A. (Tecnoflon), HaloPolymer (Elaftor), Gujarat Fluorochemicals (Fluonox), and several Chinese manufacturers. Fluoroelastomers are more expensive than neoprene or nitrile rubber elastomers. They provide additional heat and chemical resistance. FKMs can be divided into different classes on the basis of either their chemical composition, their fluorine content, or their cross-linking mechanism. |
Analogy | Analogy is a comparison or correspondence between two things (or two groups of things) because of a third element that they are considered to share.In logic, it is an inference or an argument from one particular to another particular, as opposed to deduction, induction, and abduction. It is also used of where at least one of the premises, or the conclusion, is general rather than particular in nature. It has the general form A is to B as C is to D. |
N-player game | In game theory, an n-player game is a game which is well defined for any number of players. This is usually used in contrast to standard 2-player games that are only specified for two players. In defining n-player games, game theorists usually provide a definition that allow for any (finite) number of players. The limiting case of n→∞ is the subject of mean field game theory.Changing games from 2-player games to n-player games entails some concerns. For instance, the Prisoner's dilemma is a 2-player game. One might define an n-player Prisoner's Dilemma where a single defection results everyone else getting the sucker's payoff. Alternatively, it might take certain amount of defection before the cooperators receive the sucker's payoff. (One example of an n-player Prisoner's Dilemma is the Diner's dilemma.) |
Small cubicuboctahedron | In geometry, the small cubicuboctahedron is a uniform star polyhedron, indexed as U13. It has 20 faces (8 triangles, 6 squares, and 6 octagons), 48 edges, and 24 vertices. Its vertex figure is a crossed quadrilateral.
The small cubicuboctahedron is a faceting of the rhombicuboctahedron. Its square faces and its octagonal faces are parallel to those of a cube, while its triangular faces are parallel to those of an octahedron: hence the name cubicuboctahedron. The small suffix serves to distinguish it from the great cubicuboctahedron, which also has faces in the aforementioned directions. |
Integrability conditions for differential systems | In mathematics, certain systems of partial differential equations are usefully formulated, from the point of view of their underlying geometric and algebraic structure, in terms of a system of differential forms. The idea is to take advantage of the way a differential form restricts to a submanifold, and the fact that this restriction is compatible with the exterior derivative. This is one possible approach to certain over-determined systems, for example, including Lax pairs of integrable systems. A Pfaffian system is specified by 1-forms alone, but the theory includes other types of example of differential system. To elaborate, a Pfaffian system is a set of 1-forms on a smooth manifold (which one sets equal to 0 to find solutions to the system). |
Poll (Unix) | poll is a POSIX system call to wait for one or more file descriptors to become ready for use.On *BSD and macOS, it has been largely superseded by kqueue in high performance applications. On Linux, it has been superseded by ppoll and epoll. |
ISO 31-13 | ISO 31 (Quantities and units, International Organization for Standardization, 1992) is a superseded international standard concerning physical quantities, units of measurement, their interrelationships and their presentation. It was revised and replaced by ISO/IEC 80000. |
Tetra-tert-butylethylene | Tetra-tert-butylethylene is a hypothetical organic compound, a hydrocarbon with formula C18H36, or ((H3C−)3C−)2C=C(−C(−CH3)3)2. As the name indicates, its molecular structure can be viewed as an ethylene molecule H2C=CH2 with the four hydrogens replaced by tert-butyl −C(−CH3)3 groups.
As of 2006, this compound had not yet been synthesized, in spite of many efforts. It is of interest in chemical research as an alkene whose double bond is strained but protected by steric hindrance. Theoretical studies indicate that the molecule should be stable, with a strain energy of about 93 kcal/mol (390 kJ/mol). |
Vertical circle | In astronomy, a vertical circle is a great circle on the celestial sphere that is perpendicular to the horizon. Therefore, it contains the vertical direction, passing through the zenith and the nadir. There is a vertical circle for any given azimuth, where azimuth is the angle measured east from the north on the celestial horizon. The vertical circle which is on the east–west direction is called the prime vertical. The vertical circle which is on the north–south direction is called the local celestial meridian (LCM), or principal vertical. Vertical circles are part of the horizontal coordinate system.Instruments like this were more common in 19th century observatories and were important for locating and recording coordinates in the cosmos, and observatories often had various other instruments for certain functions as well as advanced clocks of the period. The popularly known example in the observatories, were the Great refractors which became larger and larger and came to have dominating effect to the point that observatories were moved simply to have better conditions for their biggest telescope, in the modern style where observatories often have one instrument only in a remote location on the Earth or even in outer space. However, in the 19th century it was more basic with observatorys often making recording of coordinates of different items and to determine the shape of the Earth and times. |
Feelix Growing | Feelix Growing is a research project, started on December 1, 2006, that is working to design robots that can detect and respond to human emotional cues. The project involves six countries and 25 roboticists, developmental psychologists and neuroscientists.The aim of the project was to build robots that "learn from humans and respond in a socially and emotionally appropriate manner". The robots are designed to respond to emotional cues from humans and use them to adapt their own behavior. The project designers wanted to facilitate integration of robots into human society so that they could more easily provide services. The project aims to create robots that can "recognize" a given emotion, such as anger or fear, in a human, and adapt its behavior to the most appropriate response after repeated interactions. Thus the project emphasizes development over time. |
SOL3 | SOL3 is an American footwear company that designs and produces shoe accessories, which range from manufacturing insoles such as shoe lifts and crease protectors to various basic foot care items including laces, deodorizer, socks and sneaker cleaner. Based in Philadelphia and founded as of late-2016, SOL3 launched the original ternary adjustable height insoles that can be modified to increase elevation in footwear from 1 to 2.36 inches. The company first began distributing and shipping product globally in October 2016. As of December 2017, SOL3 sold an estimated 50,000 units of the 3-Level Insole after its first year of operation. In 2018, SOL3 was named “Footwear Accessory of the Year” by Sneakscore. |

Journal of Computer Graphics Techniques | The Journal of Computer Graphics Techniques is a diamond open-access peer-reviewed scientific journal covering computer graphics. It was established in May 2012 when a large part of the editorial board resigned from the now-defunct Journal of Graphics Tools. The editor-in-chief is Marc Olano (University of Maryland, Baltimore County). |
Importin subunit alpha-4 | Importin subunit alpha-4 also known as karyopherin subunit alpha-3 is a protein that in humans is encoded by the KPNA3 gene.The transport of molecules between the nucleus and the cytoplasm in eukaryotic cells is mediated by the nuclear pore complex (NPC) which consists of 60–100 proteins and is probably 120 million daltons in molecular size. Small molecules (up to 70 kD) can pass through the nuclear pore by nonselective diffusion; larger molecules are transported by an active process. Most nuclear proteins contain short basic amino acid sequences known as nuclear localization signals (NLSs). KPNA3, encodes a protein similar to certain nuclear transport proteins of Xenopus and human. The predicted amino acid sequence shows similarity to Xenopus importin, yeast SRP1, and human RCH1 (KPNA2), respectively. The similarities among these proteins suggests that karyopherin alpha-3 may be involved in the nuclear transport system. |
Free-space optical communication | Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or something similar. This contrasts with using solids such as optical fiber cable.
The technology is useful where the physical connections are impractical due to high costs or other considerations. |
Constant curvature | In mathematics, constant curvature is a concept from differential geometry. Here, curvature refers to the sectional curvature of a space (more precisely a manifold) and is a single number determining its local geometry. The sectional curvature is said to be constant if it has the same value at every point and for every two-dimensional tangent plane at that point. For example, a sphere is a surface of constant positive curvature. |
Azane | Azanes are acyclic, saturated hydronitrogens, which means that they consist only of hydrogen and nitrogen atoms and all bonds are single bonds. They are therefore pnictogen hydrides. Because cyclic hydronitrogens are excluded by definition, the azanes comprise a homologous series of inorganic compounds with the general chemical formula NnHn+2. Each nitrogen atom has three bonds (either N-H or N-N bonds), and each hydrogen atom is joined to a nitrogen atom (H-N bonds). A series of linked nitrogen atoms is known as the nitrogen skeleton or nitrogen backbone. The number of nitrogen atoms is used to define the size of the azane (e.g. N2-azane). |
Relative Gain Array | The Relative Gain Array (RGA) is a classical widely-used method for determining the best input-output pairings for multivariable process control systems. It has many practical open-loop and closed-loop control applications and is relevant to analyzing many fundamental steady-state closed-loop system properties such as stability and robustness. |
Polytomous choice | In economics, polytomous choice is a setting (model) with more than two choices; contrast to dichotomous choice. The use of the term polychotomous is also in common usage in the prior research literature; however, polytomous is the more technically correct spelling. |
Truncated order-4 hexagonal tiling | In geometry, the truncated order-4 hexagonal tiling is a uniform tiling of the hyperbolic plane. It has Schläfli symbol of t{6,4}. A secondary construction tr{6,6} is called a truncated hexahexagonal tiling with two colors of dodecagons. |
FOXL2 | Forkhead box protein L2 is a protein that in humans is encoded by the FOXL2 gene. |
Brown HT | Brown HT, also called Chocolate Brown HT, Food Brown 3, and C.I. 20285, is a brown synthetic coal tar diazo dye. |
Linux namespaces | Namespaces are a feature of the Linux kernel that partitions kernel resources such that one set of processes sees one set of resources while another set of processes sees a different set of resources. The feature works by having the same namespace for a set of resources and processes, but those namespaces refer to distinct resources. Resources may exist in multiple spaces. Examples of such resources are process IDs, host-names, user IDs, file names, some names associated with network access, and Inter-process communication. |
Urodynamic testing | Urodynamic testing or urodynamics is a study that assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests can help explain symptoms such as: incontinence frequent urination sudden, strong urges to urinate but nothing comes out problems starting a urine stream painful urination problems emptying the bladder completely (Vesical tenesmus, detrusor failure) recurrent urinary tract infectionsUrodynamic tests are usually performed in Urology, Gynecology, OB/GYN, Internal medicine, and Primary care offices. Urodynamics will provide the physician with the information necessary to diagnose the cause and nature of a patient's incontinence, thus giving the best treatment options available. Urodynamics is typically conducted by urologists or urogynecologists. |
Shuf | shuf is a command-line utility included in the textutils package of GNU Core Utilities for creating a standard output consisting of random permutations of the input.
The version of shuf bundled in GNU coreutils was written by Paul Eggert. It is not a part of POSIX. |
Cortisol awakening response | The cortisol awakening response (CAR) is an increase between 38% and 75% in cortisol levels peaking 30–45 minutes after awakening in the morning in some people. This rise is superimposed upon the late-night rise in cortisol which occurs before awakening. While its purpose is uncertain, it may be linked to the hippocampus' preparation of the hypothalamic-pituitary-adrenal axis (HPA) in order to face anticipated stress. |
Unimodality | In mathematics, unimodality means possessing a unique mode. More generally, unimodality means there is only a single highest value, somehow defined, of some mathematical object. |
HaloTag | HaloTag is a self-labeling protein tag. It is a 297 residue protein (33 kDa) derived from a bacterial enzyme, designed to covalently bind to a synthetic ligand. The bacterial enzyme can be fused to various proteins of interest. The synthetic ligand is chosen from a number of available ligands in accordance with the type of experiments to be performed. This bacterial enzyme is a haloalkane dehalogenase, which acts as a hydrolase and is designed to facilitate visualization of the subcellular localization of a protein of interest, immobilization of a protein of interest, or capture of the binding partners of a protein of interest within its biochemical environment. The HaloTag is composed of two covalently bound segments including a haloalkane dehalogenase and a synthetic ligand of choice. These synthetic ligands consist of a reactive chloroalkane linker bound to a functional group. Functional groups can either be biotin (can be used as an affinity tag) or can be chosen from five available fluorescent dyes including Coumarin, Oregon Green, Alexa Fluor 488, diAcFAM, and TMR. These fluorescent dyes can be used in the visualization of either living or chemically fixed cells. |
Curse of knowledge | The curse of knowledge is a cognitive bias that occurs when an individual, who is communicating with other individuals, assumes that other individuals have similar background and depth of knowledge to understand. This bias is also called by some authors the curse of expertise.For example, in a classroom setting, teachers may have difficulty if they cannot put themselves in the position of the student. A knowledgeable professor might no longer remember the difficulties that a young student encounters when learning a new subject for the first time. This curse of knowledge also explains the danger behind thinking about student learning based on what appears best to faculty members, as opposed to what has been verified with students. |
Deposit slip | A deposit slip is a form supplied by a bank for a depositor to fill out, designed to document in categories the items included in the deposit transaction. The categories include type of item, and if it is a cheque, where it is from such as a local bank or a state if the bank is not local. The teller keeps the deposit slip along with the deposit (cash and cheques), and provides the depositor with a receipt. They are filled in a store and not a bank, so it is very convenient in paying. They also are a means of transport of money. Pay-in slips encourage the sorting of cash and coins, are filled in and signed by the person who deposited the money, and some tear off from a record that is also filled in by the depositor. Deposit slips are also called deposit tickets and come in a variety of designs. They are signed by the depositor if the depositor is cashing some of the accompanying check and depositing the rest. |
GPD1L | GPD1L is a human gene. The protein encoded by this gene contains a glycerol-3-phosphate dehydrogenase (NAD+) motif and shares 72% sequence identity with GPD1. |
Packet Design | Packet Design is an Austin, Texas-based network performance management software company credited with pioneering route analytics technology. This network monitoring technology analyzes routing protocols and structures in meshed IP networks by participating as a peer in the network to passively “listen” to Layer 3 routing protocol exchanges between routers for the purpose of network discovery, mapping, real-time monitoring and routing diagnostics.The company maintains offices in San Jose, CA, Austin, TX, Dubai, UAE, and Pune, India. In June 2018, Ciena announced it would acquire Packet Design LLC and the transaction closed July 2, 2018. |
Dive start | A dive start is the action begun at the start of a swimming race. In most strokes, the swimmer jumps off the diving blocks after hearing the starting signal. However, if it is a backstroke event, the swimmers will be starting in the water. All dives are followed by a streamline just like turning. |
PANTHER | In bioinformatics, the PANTHER (protein analysis through evolutionary relationships) classification system is a large curated biological database of gene/protein families and their functionally related subfamilies that can be used to classify and identify the function of gene products. PANTHER is part of the Gene Ontology Reference Genome Project designed to classify proteins and their genes for high-throughput analysis. |
Homocapsaicin | Homocapsaicin is a capsaicinoid and analog and congener of capsaicin in chili peppers (Capsicum). Like capsaicin it is an irritant. Homocapsaicin accounts for about 1% of the total capsaicinoids mixture and has about half the pungency of capsaicin. Pure homocapsaicin is a lipophilic colorless odorless crystalline to waxy compound. On the Scoville scale it has 8,600,000 SHU (Scoville heat units). Homocapsaicin isolated from chili pepper has been found in two isomeric forms, both with a carbon-carbon double bond at the 6 position (numbered from the amide carbon) on the 10-carbon acyl chain. One isomer has an additional carbon, a methyl group, at the 8 position and the other has a methyl group at the 9 position. Homocapsaicin (6-ene-8-methyl) is the more abundant isomer. Homocapsaicin with the double bond at the 7 position has never been found in nature, though its structure is widely reported on the Internet and in the scientific literature. Details of this misidentification have been published. |
Associative magic square | An associative magic square is a magic square for which each pair of numbers symmetrically opposite to the center sum up to the same value. For an n × n square, filled with the numbers from 1 to n2, this common sum must equal n2 + 1. These squares are also called associated magic squares, regular magic squares, regmagic squares, or symmetric magic squares. |
Holoscenes | Holoscenes is a multi-format work of installation art by Los Angeles artist Lars Jan. |
Nandrolone | Nandrolone, also known as 19-nortestosterone, is an endogenous androgen which exists in the male body at a ratio of 1:50 compared to testosterone. It is also an anabolic steroid (AAS) which is medically used in the form of esters such as nandrolone decanoate (brand name Deca-Durabolin) and nandrolone phenylpropionate (brand name Durabolin). Nandrolone esters are used in the treatment of anemias, cachexia (muscle wasting syndrome), osteoporosis, breast cancer, and for other indications. They are not used by mouth and instead are given by injection into muscle or fat.Side effects of nandrolone esters include symptoms of masculinization like acne, increased hair growth, and voice changes; and decreased sexual desire in men due to its ability to suppress endogenous testosterone synthesis while not being a sufficient androgen itself. They are synthetic androgens and anabolic steroids and hence are agonists of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). Nandrolone has strong anabolic effects and weak androgenic effects, which give them a mild side effect profile and make them especially suitable for use in women and children. There are metabolites of Nandrolone that act as long-lasting prodrugs in the body, such as 5α-Dihydronandrolone. |
Diurnal motion | Diurnal motion (from Latin diurnus 'daily', from Latin diēs 'day') is an astronomical term referring to the apparent motion of celestial objects (e.g. the Sun and stars) around Earth, or more precisely around the two celestial poles, over the course of one day. It is caused by Earth's rotation around its axis, so almost every star appears to follow a circular arc path, called the diurnal circle, often depicted in star trail photography. |
Facial prosthetic | A facial prosthetic or facial prosthesis is an artificial device used to change or adapt the outward appearance of a person's face or head. |
Genetic erosion | Genetic erosion (also known as genetic depletion) is a process where the limited gene pool of an endangered species diminishes even more when reproductive individuals die off before reproducing with others in their endangered low population. The term is sometimes used in a narrow sense, such as when describing the loss of particular alleles or genes, as well as being used more broadly, as when referring to the loss of a phenotype or whole species. |
Activity-driven model | In network science, the activity-driven model is a temporal network model in which each node has a randomly-assigned "activity potential", which governs how it links to other nodes over time. Each node j (out of N total) has its activity potential xi drawn from a given distribution F(x) . A sequence of timesteps unfolds, and in each timestep each node j forms ties to m random other nodes at rate ai=ηxi (more precisely, it does so with probability aiΔt per timestep). All links are then deleted after each timestep. |
Dorrite | Dorrite is a silicate mineral that is isostructural to the aenigmatite group. Although it is most chemically similar to the mineral rhönite [Ca2Mg5Ti(Al2Si4)O20], the lack of titanium (Ti) and presence of Fe3+ influenced dorrite's independence. Dorrite is named for Dr. John (Jack) A. Dorr, a late professor at the University of Michigan that researched in outcrops where dorrite was found in 1982. This mineral is sub-metallic resembling colors of brownish-black, dark brown, to reddish brown. |
Master of Information Management | A Master of Information Management (MIM) is an interdisciplinary degree program designed to provide studies in strategic information management, knowledge management, usability, business administration, information systems, information architecture, information design, computer sciences, policy, ethics, and project management. The degree is relatively new and has typically been developed alongside other, more established programs in university Schools of Information. The MIM degree has emerged to address the growing and unique need for information professionals who understand the conflux of multiple organizational issues across several disciplines. |
Versatile Service Engine | Versatile Service Engine is a second generation IP Multimedia Subsystem developed by Nortel Networks that is compliant with Advanced Telecommunications Computing Architecture specifications. Nortel's versatile service engine provides capability to telecommunication service provider to offer global System for mobile communications and code-division multiple access services in both wireline and wireless mode. |
Material flow | Material flow is the description of the transportation of raw materials, pre-fabricates, parts, components, integrated objects and final products as a flow of entities. The term applies mainly to advanced modeling of supply chain management.
As industrial material flow can easily become very complex, several different specialized simulation tools have been developed for complex systems. Typical tools are: AnyLogic AutoMod for logistics systems Plant Simulation for production system |
Dithiane | A dithiane is a heterocyclic compound composed of a cyclohexane core structure wherein two methylene bridges (-CH2- units) are replaced by sulfur centres. The three isomeric parent heterocycles are 1,2-dithiane, 1,3-dithiane and 1,4-dithiane. |
Erythropoietin receptor | The erythropoietin receptor (EpoR) is a protein that in humans is encoded by the EPOR gene. EpoR is a 52kDa peptide with a single carbohydrate chain resulting in an approximately 56-57 kDa protein found on the surface of EPO responding cells. It is a member of the cytokine receptor family. EpoR pre-exists as dimers. These dimers were originally thought to be formed by extracellular domain interactions, however, it is now assumed that it is formed by interactions of the transmembrane domain and that the original structure of the extracellular interaction site was due to crystallisation conditions and does not depict the native conformation. Binding of a 30 kDa ligand erythropoietin (Epo), changes the receptor's conformational change, resulting in the autophosphorylation of Jak2 kinases that are pre-associated with the receptor (i.e., EpoR does not possess intrinsic kinase activity and depends on Jak2 activity). At present, the most well-established function of EpoR is to promote proliferation and rescue of erythroid (red blood cell) progenitors from apoptosis. |
PSTPIP1 | Proline-serine-threonine phosphatase-interacting protein 1 is an enzyme that in humans is encoded by the PSTPIP1 gene. |
Ilinx | Ilinx is a kind of play, described by sociologist Roger Caillois, a major figure in game studies. Ilinx creates a temporary disruption of perception, as with vertigo, dizziness, or disorienting changes in direction of movement. |
Aluminium toxicity in people on dialysis | Aluminium toxicity in people on dialysis is a problem for people on haemodialysis. The dialysis process does not efficiently remove excess aluminium from the body, so it may build up over time. Aluminium is a potentially toxic metal, and aluminium poisoning may lead to mainly three disorders: aluminium-induced bone disease, microcytic anemia and neurological dysfunction (encephalopathy). Such conditions are more prominently observed in people with chronic kidney failure and especially in people on haemodialysis. |
Electric chair | The electric chair is a specialized device employed for carrying out capital punishment through the process of electrocution. During its use, the individual sentenced to death is securely strapped to a specifically designed wooden chair and subjected to electrocution via strategically positioned electrodes affixed to the head and leg. This method of execution was conceptualized by Alfred P. Southwick, a dentist based in Buffalo, New York, in 1881. Over the following decade, this execution technique was developed further, aiming to provide a more humane alternative to the conventional form of execution, particularly hanging. The electric chair was first utilized in 1890 and subsequently became known as a symbol of this method of execution. |
Joint compatibility branch and bound | Joint compatibility branch and bound (JCBB) is an algorithm in computer vision and robotics commonly used for data association in simultaneous localization and mapping. JCBB measures the joint compatibility of a set of pairings that successfully rejects spurious matchings and is hence known to be robust in complex environments. |
Process psychology | Process psychology is a branch of psychotherapeutic psychology which was derived from process philosophy as developed by Alfred North Whitehead. Process psychology got its start at a conference sponsored by the Center for Process Studies in 1998. In 2000, Michel Weber created the Whitehead Psychology Nexus: an open forum dedicated to the cross-examination of Alfred North Whitehead's process philosophy and the various facets of the contemporary psychological field.David Ray Griffin, a retired professor, has also been instrumental in encouraging the development of Process Psychology. Process Psychology is closely aligned with process theology and its practitioners frequently refer to spiritual concerns. |
Divine light | In theology, divine light (also called divine radiance or divine refulgence) is an aspect of divine presence perceived as light during a theophany or vision, or represented as such in allegory or metaphor.
The term "light" has been widely used in spirituality and religion, such as: An Nūr – Islamic term and concept, referenced in Surah an-Nur and Ayat an-Nur of the Quran.
Inner light – Christian concept and Quaker doctrine.
Jyoti or Jyot – a holy flame that is lit with cotton wicks and ghee or mustard oil. It is the prayer ritual of devotional worship performed by Hindus offer to the deities. Jyoti is also a representation of the divine light and a form of the Hindu goddess Durga shakti.
Ohr Ein Sof – in Rabbinic Judaism and Kabbalah.
Prakāśa – Kashmiri Shaiva concept of the light of Divine Consciousness of Shiva.
Tabor Light – the uncreated light revealed to the apostles present during the Transfiguration of Jesus; also experienced as illumination on the path to theosis in Eastern Orthodox theology during theoria, a form of Christian contemplation. |
Master-checker | A master-checker is a hardware-supported fault tolerance method for multiprocessor systems, in which two processors, referred to as the master and checker, calculate the same functions in parallel in order to increase the probability that the result is exact. The checker-CPU is synchronised at clock level with the master-CPU and processes the same programs as the master. Whenever the master-CPU generates an output, the checker-CPU compares this output to its own calculation and in the event of a difference raises a warning. |
Oppo Joy Plus | The Oppo Joy Plus launched at the end of April, 2015. The phone had the slogan "Leap Up, Reach Joy." One of the phone's key selling points was an improved touchscreen which utilized an "all-new touch IC chip" which would allow users to user the device while wearing gloves or wet. |
60S ribosomal protein L32 | 60S ribosomal protein L32 is a protein that in humans is encoded by the RPL32 gene.Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 60S subunit. The protein belongs to the L32E family of ribosomal proteins. It is located in the cytoplasm. Although some studies have mapped this gene to 3q13.3-q21, it is believed to map to 3p25-p24. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. Alternatively spliced transcript variants encoding the same protein have been observed for this gene. |
