Allyltestosterone | Allyltestosterone, or 17α-allyltestosterone, also known as 17α-allylandrost-4-en-17β-ol-3-one, is a steroid derived from testosterone that was first synthesized in 1936 and was never marketed. Along with propyltestosterone (topterone), it has been patented as a topical antiandrogen and hair growth inhibitor. Allyltestosterone is the parent structure of two marketed 19-nortestosterone progestins, allylestrenol and altrenogest. These progestins are unique among testosterone derivatives in that they appear to be associated with few or no androgenic effects. |
Mars Multispectral Imager for Subsurface Studies | Mars Multispectral Imager for Subsurface Studies (MA-MISS) is a miniaturized imaging spectrometer designed to provide imaging and spectra by reflectance in the near-infrared (NIR) wavelength region and determine the mineral composition and stratigraphy. The instrument is part of the science payload on board the European Rosalind Franklin rover, tasked to search for biosignatures, and scheduled to land on Mars in spring 2023. MA-MISS is essentially inside a drill on the Rover, and will take measurements of the sub-surface directly. |
Interpolation space | In the field of mathematical analysis, an interpolation space is a space which lies "in between" two other Banach spaces. The main applications are in Sobolev spaces, where spaces of functions that have a noninteger number of derivatives are interpolated from the spaces of functions with integer number of derivatives. |
Mobile VoIP | Mobile VoIP or simply mVoIP is an extension of mobility to a voice over IP network. Two types of communication are generally supported: cordless telephones using DECT or PCS protocols for short range or campus communications where all base stations are linked into the same LAN, and wider area communications using 3G or 4G protocols. |
Veronica bucket | The Veronica bucket is a mechanism for hand washing originating in Ghana which consists of a bucket of water with a tap fixed at the bottom, mounted at hand height, and a bowl at the bottom to collect waste water. The Veronica bucket was developed by Veronica Bekoe. The Veronica bucket serves as a simple way to encourage proper hand washing using flowing water. Bekoe in an interview stated that the bucket was originally made to help her and her colleagues wash their hands under running water after each lab session. She said, "We are used to washing hands in a bowl with others washing in the same water, which will do more harm than good." These colleagues were contaminating their hands rather than decontaminating them. In addition to the COVID benefit of hand washing, the Veronica bucket is also essential for areas where potable water is not readily available. |
Physical health in schizophrenia | People with schizophrenia are at a higher than average risk of physical ill health, and earlier death than the general population. The fatal conditions include cardiovascular, respiratory and metabolic disorders.Although death by suicide in schizophrenia has received much needed attention, and is the leading cause of death among males, death from cardiovascular disease is more common in females, accounting for up to 75 percent of deaths. The causes of physical health problems include factors associated with mental illness and its treatment, poverty, poor housing, higher rates of smoking, poor diet and lack of exercise. |
Retail marketing | Once the strategic plan is in place, retail managers turn to the more managerial aspects of planning. A retail mix is devised for the purpose of coordinating day-to-day tactical decisions. The retail marketing mix typically consists of six broad decision layers including product decisions, place decisions, promotion, price, personnel and presentation (also known as physical evidence). The retail mix is loosely based on the marketing mix, but has been expanded and modified in line with the unique needs of the retail context. A number of scholars have argued for an expanded marketing, mix with the inclusion of two new Ps, namely, Personnel and Presentation since these contribute to the customer's unique retail experience and are the principal basis for retail differentiation. Yet other scholars argue that the Retail Format (i.e. retail formula) should be included. The modified retail marketing mix that is most commonly cited in textbooks is often called the 6 Ps of retailing (see diagram at right). |
Cognos ReportNet | Cognos ReportNet (CRN) was a web-based software product for creating and managing ad hoc and custom-made reports. ReportNet was developed by the Ottawa-based company Cognos (formerly Cognos Incorporated), an IBM company. The web-based reporting tool was launched in September 2003. Since IBM's acquisition of Cognos, ReportNet has been renamed IBM Cognos ReportNet like all other Cognos products. |
Tris(8-hydroxyquinolinato)aluminium | Tris(8-hydroxyquinolinato)aluminium is the chemical compound with the formula Al(C9H6NO)3. Widely abbreviated Alq3, it is a coordination complex wherein aluminium is bonded in a bidentate manner to the conjugate base of three 8-hydroxyquinoline ligands. |
Smart Battery System | Smart Battery System (SBS) is a specification for managing a smart battery, usually for a portable computer. It allows operating systems to perform power management operations via a smart battery charger based on remaining estimated run times by determining accurate state of charge readings. Through this communication, the system also controls the battery charge rate. Communication is carried over an SMBus two-wire communication bus. The specification originated with the Duracell and Intel companies in 1994, but was later adopted by several battery and semiconductor makers.The Smart Battery System defines the SMBus connection, the data that can be sent over the connection (Smart Battery Data or SBD), the Smart Battery Charger, and a computer BIOS interface for control. In principle, any battery operated product can use SBS. |
Strat-O-Matic Computer Baseball | Strat-O-Matic Computer Baseball is a 1986 video game published by Strat-O-Matic. |
Turbofan | The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the fan, a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. |
Oil body | An oil body is a lipid-containing structure found in plant cells. The term can refer to at least two distinct kinds of structures in different kinds of plants. |
Lindenbaum–Tarski algebra | In mathematical logic, the Lindenbaum–Tarski algebra (or Lindenbaum algebra) of a logical theory T consists of the equivalence classes of sentences of the theory (i.e., the quotient, under the equivalence relation ~ defined such that p ~ q exactly when p and q are provably equivalent in T). That is, two sentences are equivalent if the theory T proves that each implies the other. The Lindenbaum–Tarski algebra is thus the quotient algebra obtained by factoring the algebra of formulas by this congruence relation. |

AGN-2979 | AGN-2979 is a glutarimide tryptophan hydroxylase activation inhibitor. It shows antidepressant properties in rodent models of depression. |
Stratus nebulosus | Stratus nebulosus is a species of low-level stratus cloud.
It is one of only two species that is associated with stratus clouds, other being fractus.
Translated from Latin meaning nebulous, their cloud abbreviations can be respectively written as ‘St neb’. For a cloud to be classified as nebulosus, there has to be zero sign of detail in the cloud.
Low-level fog is an example of stratus nebulosus. |
Technological utopianism | Technological utopianism (often called techno-utopianism or technoutopianism) is any ideology based on the premise that advances in science and technology could and should bring about a utopia, or at least help to fulfill one or another utopian ideal. |
Liquid color | The term liquid color or liquid color concentrate describes to a system consisting of a liquid binder (carrier), dyes or pigments and other additives such as process additives, stabilisers or similar. The liquid colors are mixed into the plastic (raw polymer or recyclat) for coloring or changing the properties.In general, there are three groups of liquid colors.
Liquid colors, which are used to color plastic products.Liquid additive concentrates that provide specific properties in the end products, such as UV stabilization, flame retardancy, antistatic or anti-blocking.Combination liquid colors that contain both colorants and additives. |
Electronic trading platform | In finance, an electronic trading platform also known as an online trading platform, is a computer software program that can be used to place orders for financial products over a network with a financial intermediary. Various financial products can be traded by the trading platform, over a communication network with a financial intermediary or directly between the participants or members of the trading platform. This includes products such as stocks, bonds, currencies, commodities, derivatives and others, with a financial intermediary, such as brokers, market makers, Investment banks or stock exchanges. Such platforms allow electronic trading to be carried out by users from any location and are in contrast to traditional floor trading using open outcry and telephone based trading. Sometimes the term trading platform is also used in reference to the trading software alone. Electronic trading platforms typically stream live market prices on which users can trade and may provide additional trading tools, such as charting packages, news feeds and account management functions. Some platforms have been specifically designed to allow individuals to gain access to financial markets that could formerly only be accessed by specialist trading firms using direct market access. They may also be designed to automatically trade specific strategies based on technical analysis or to do high-frequency trading. |
Coolhunting | Coolhunting is a neologism coined in the early 1990s referring to a new kind of marketing professionals who make observations and predictions in changes of new or existing "cool" cultural fads and trends. Coolhunting is also referred to as "trend spotting," and is a subset of trend analysis.
Coolhunters resemble the intuitive fashion magazine editors of the 1960s such as Nancy White (Harper's Bazaar 1958–1971). Coolhunters operate mostly in the world of street fashion and design, but their work also blurs into that of futurists such as Faith Popcorn. |
Dynamic data | In data management, dynamic data or transactional data is information that is periodically updated, meaning it changes asynchronously over time as new information becomes available. The concept is important in data management, since the time scale of the data determines how it is processed and stored.
Data that is not dynamic is considered either static (unchanging) or persistent, which is data that is infrequently accessed and not likely to be modified. Dynamic data is also different from streaming data, which is a constant flow of information. Dynamic data may be updated at any time, with periods of inactivity in between. |
Radionuclide angiography | Radionuclide angiography is an area of nuclear medicine which specialises in imaging to show the functionality of the right and left ventricles of the heart, thus allowing informed diagnostic intervention in heart failure. It involves use of a radiopharmaceutical, injected into a patient, and a gamma camera for acquisition. A MUGA scan (multigated acquisition) involves an acquisition triggered (gated) at different points of the cardiac cycle. MUGA scanning is also called equilibrium radionuclide angiocardiography, radionuclide ventriculography (RNVG), or gated blood pool imaging, as well as SYMA scanning (synchronized multigated acquisition scanning). |
Esketamine | Esketamine, also known as (S)-ketamine or S(+)-ketamine, is the S(+) enantiomer of ketamine, is a dissociative hallucinogen drug used as a general anesthetic and as an antidepressant for treatment of depression. It is sold under the brand names Spravato (for depression), Ketanest (for anesthesia), among others. Esketamine is the active enantiomer of ketamine in terms of NMDA receptor antagonism and is more potent than racemic ketamine.It is specifically used as a therapy for treatment-resistant depression (TRD) and for major depressive disorder (MDD) with co-occurring suicidal ideation or behavior. Its effectiveness for depression is modest and similar to that of other antidepressants. Esketamine is not used by infusion into a vein for anesthesia as it is only FDA approved for depression in the form of an intranasal spray (the parent compound Ketamine is most often administered intravenously) and under direct medical supervision as a nasal spray.Adverse effects of esketamine include dissociation, dizziness, sedation, nausea, vomiting, vertigo, numbness, anxiety, lethargy, increased blood pressure, and feelings of drunkenness. Less often, esketamine can cause bladder problems. Esketamine acts primarily as a N-methyl-D-aspartate (NMDA) receptor antagonist but also has other actions.In the form of racemic ketamine, esketamine was first synthesized in 1962 and introduced for medical use as an anesthetic in 1970. Enantiopure esketamine was introduced for medical use as an anesthetic in 1997 and as an antidepressant in 2019. It is used as an anesthetic in the European Union and as an antidepressant in the United States and Canada. Due to misuse liability as a dissociative hallucinogen, esketamine is a controlled substance. |
Re-recording mixer | A re-recording mixer in North America, also known as a dubbing mixer in Europe, is a post-production audio engineer who mixes recorded dialogue, sound effects and music to create the final version of a soundtrack for a feature film, television program, or television advertisement. The final mix must achieve a desired sonic balance between its various elements, and must match the director's or sound designer's original vision for the project. For material intended for broadcast, the final mix must also comply with all applicable laws governing sound mixing (e.g., the CALM Act in the United States and the EBU R 128 loudness protocol in Europe). |
Pre-established harmony | The mind–body problem is a philosophical problem concerning the relationship between thought and consciousness in the human mind, and the body.The issue is this. Though it is obvious that mental events and physical events are somehow related, it is not obvious what the nature of this relation is. For example, it is obvious that feelings of sadness (which are mental events) will cause people to cry (which is a physical state of the body), or that finding a joke funny (a mental event) will cause one to laugh (another bodily state), or that feelings of pain (in the mind) will cause avoidance behaviours (in the body), and so on. Similarly, it is well known that changing the chemistry of the body (and the brain especially) via drugs (such as antipsychotics, SSRIs, or alcohol) can change one's state of mind in nontrivial ways. Or, in the other direction, it is known that therapeutic interventions like cognitive behavioural therapy will change cognition in ways that have downstream effects on the bodily health. These are only a few examples of the numerous ways in which the state of the mind and body seem to be intimately tied; many more examples can be found simply by reflecting on one's day-to-day experiences. |
Non-broadcast multiple-access network | A non-broadcast multiple access network (NBMA) is a computer network to which multiple hosts are attached, but data is transmitted only directly from one computer to another single host over a virtual circuit or across a switched fabric. |
(RS)-MCPG | (RS)-MCPG is a phenylglycine derivative and a non-selective antagonist of group I and II metabotropic glutamate receptors (mGluRs). It has been used in long-term potentiation (LTP) as well as long-term depression (LTD) research and proved that certain LTP and LTD pathways depend on mGluRs. Its full chemical name is (RS)-α-methyl-4-carboxyphenylglycine. It appears as a white solid and its molecular weight is 209.2 Da. Its molecular formula is C10H11NO4. |
Joint Institute for Nuclear Astrophysics | The Joint Institute for Nuclear Astrophysics Center for the Evolution of the Elements (JINA-CEE) is a multi-institutional Physics Frontiers Center funded by the US National Science Foundation since 2014. From 2003 to 2014, JINA was a collaboration between Michigan State University, the University of Notre Dame, the University of Chicago, and directed by Michael Wiescher from the University of Notre Dame. Principal investigators were Hendrik Schatz, Timothy Beers and Jim Truran.JINA-CEE is a collaboration between Michigan State University, the University of Notre Dame, University of Washington and Arizona State University and a number of associated institutions, centers, and national laboratories in the US and across the world, with the goal to bring together nuclear experimenters, nuclear theorists, astrophysical modelers, astrophysics theorists, and observational astronomers to address the open scientific questions at the intersection of nuclear physics and astrophysics. JINA-CEE serves as an intellectual center and focal point for the field of nuclear astrophysics, and is intended to enable scientific work and exchange of data and information across field boundaries within its collaboration, and for the field as a whole though workshops, schools, and web-based tools and data bases. It is led by director Hendrik Schatz with Michael Wiescher, Timothy Beers, Sanjay Reddy and Frank Timmes as principal investigators. |
Unique sink orientation | In mathematics, a unique sink orientation is an orientation of the edges of a polytope such that, in every face of the polytope (including the whole polytope as one of the faces), there is exactly one vertex for which all adjoining edges are oriented inward (i.e. towards that vertex). If a polytope is given together with a linear objective function, and edges are oriented from vertices with smaller objective function values to vertices with larger objective values, the result is a unique sink orientation. Thus, unique sink orientations can be used to model linear programs as well as certain nonlinear programs such as the smallest circle problem. |
Federated identity | A federated identity in information technology is the means of linking a person's electronic identity and attributes, stored across multiple distinct identity management systems.Federated identity is related to single sign-on (SSO), in which a user's single authentication ticket, or token, is trusted across multiple IT systems or even organizations. SSO is a subset of federated identity management, as it relates only to authentication and is understood on the level of technical interoperability and it would not be possible without some sort of federation. |
Alternant code | In coding theory, alternant codes form a class of parameterised error-correcting codes which generalise the BCH codes. |
Sky Ape | Sky Ape is the title character of a black-and-white comic book series. He is an ape who wears a jetpack and fights crime. |
Deterministic rendezvous problem | The deterministic rendezvous problem is a problem in computer science and robotics that involves two or more robots or players that must find each other by following a predetermined set of instructions. The goal is for the robots to meet at a specific location, or rendezvous point, without knowing the location of the other robot or robots.In the deterministic rendezvous problem, each robot follows the same set of instructions, but each robot is assigned a unique label or identifier to differentiate them from each other [2]. This unique label is used to break the symmetry of the problem, as it allows the robots to distinguish themselves from each other and to follow the instructions in a specific order [3]. |
Magmatic lull | A magmatic lull is a period of declined magmatic activity in volcanically active regions. They may occur as a result of underthrusting of hinterland lithosphere beneath a volcanic arc, changes in subduction parameters such as relative velocity, direction and slab dip (e.g. flat slab subduction), arc-arc collisions and subduction hinge advance. Individual magmatic lulls may last tens of millions of years between periods of volcanicity.A volcanic gap is a magmatic lull that separates two distinct volcanic zones. For example, the Andean Volcanic Belt of South America has three major volcanic gaps: the Peruvian flat-slab segment (3 °S–15 °S), the Pampean flat-slab segment (27 °S–33 °S) and the Patagonian Volcanic Gap (46 °S–49 °S). |
Beta-2 adrenergic receptor | The beta-2 adrenergic receptor (β2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that binds epinephrine (adrenaline), a hormone and neurotransmitter whose signaling, via adenylate cyclase stimulation through trimeric Gs proteins, increased cAMP, and downstream L-type calcium channel interaction, mediates physiologic responses such as smooth muscle relaxation and bronchodilation.Robert J.Lefkowitz and Brian Kobilka studied beta 2 adrenergic receptor as a model system which rewarded them the 2012 Nobel Prize in Chemistry “for groundbreaking discoveries that reveal the inner workings of an important family of such receptors: G-protein-coupled-receptors”. |
What Is Metaphysics? | "What Is Metaphysics?" (German: Was ist Metaphysik?) is a lecture by the philosopher Martin Heidegger, first presented to the faculties of the University of Freiburg on July 24, 1929, as inaugural address. |
Stadiametric rangefinding | Stadiametric rangefinding, or the stadia method, is a technique of measuring distances with a telescopic instrument. The term stadia comes from a Greek unit of length Stadion (equal to 600 Greek feet, pous) which was the typical length of a sports stadium of the time. Stadiametric rangefinding is used for surveying and in the telescopic sights of firearms, artillery pieces, or tank guns, as well as some binoculars and other optics. It is still widely used in long-range military sniping, but in many professional applications it is being replaced with microwave, infrared, or laser rangefinding methods. Although much easier to use, electronic rangefinders can give away the shooter's position to a well-equipped adversary, and the need for accurate range estimation existed for much longer than electronic rangefinders small and rugged enough to be suitable for military use. |
Discrete spectrum | In the physical sciences, the term spectrum was introduced first into optics by Isaac Newton in the 17th century, referring to the range of colors observed when white light was dispersed through a prism. Soon the term referred to a plot of light intensity or power as a function of frequency or wavelength, also known as a spectral density plot. |
Naphthionic acid | Naphthionic acid is an organic compound with the formula C10H6(SO3H)(NH2). It is one of several aminonaphthalenesulfonic acids, derivatives of naphthalene containing both amine and sulfonic acid functional groups. It is a white solid, although commercial samples can appear gray. It is used in the synthesis of azo dyes such as Rocceline (a. k. a. Solid Red A), during which the amino group of the acid (in the form of a salt) is diazotated and then coupled with, in the case mentioned, β-naphthol. It is prepared by treating 1-aminonaphthalene with sulfuric acid. |
Stoplogs | Stoplogs are hydraulic engineering control elements that are used in floodgates to adjust the water level or discharge in a river, canal, or reservoir. Stoplogs are sometimes confused with flashboards, as both elements are used in bulkhead or crest gates. Stoplogs are typically long rectangular timber beams or boards that are placed on top of each other and dropped into premade slots inside a weir, gate, or channel. Present day, the process of adding and removing stoplogs is not manual, but done with hydraulic stoplog lifters and hoists. Since the height of the barrier can only be adjusted through the addition and removal of stoplogs, finding a lighter and stronger material other than wood or concrete became a more desirable choice. Other materials, including steel and composites, can be used as stoplogs as well. Stoplogs are designed to cut off or stop flow through a conduit. |
International Networks (country code) | International Networks is the name given by the International Telecommunication Union (ITU) to country calling codes +882 and +883, and serves as a catch-all for telephone services not dedicated to a single country. Satellite telephone carriers, especially those with worldwide service, are allocated within the Global Mobile Satellite System (GMSS), country code +881, with the exception of non-terrestrial Inmarsat, country code 870. |
Hypoplasia | Hypoplasia (from Ancient Greek ὑπo- hypo- 'under' + πλάσις plasis 'formation'; adjective form hypoplastic) is underdevelopment or incomplete development of a tissue or organ. Although the term is not always used precisely, it properly refers to an inadequate or below-normal number of cells. Hypoplasia is similar to aplasia, but less severe. It is technically not the opposite of hyperplasia (too many cells). Hypoplasia is a congenital condition, while hyperplasia generally refers to excessive cell growth later in life. (Atrophy, the wasting away of already existing cells, is technically the direct opposite of both hyperplasia and hypertrophy.) Hypoplasia can be present in any tissue or organ. It is descriptive of many medical conditions, including underdevelopment of organs such as: Breasts during puberty Testes in Klinefelter's syndrome Ovaries in Fanconi anemia, gonadal dysgenesis, trisomy X Thymus in DiGeorge syndrome Labia majora in popliteal pterygium syndrome Corpus callosum, connecting the two sides of the brain, in agenesis of the corpus callosum Cerebellum caused by mutation in the reelin gene Tooth caused by oral pathology, such as Turner's hypoplasia Chambers of the heart in hypoplastic left heart syndrome and hypoplastic right heart syndrome Optic nerve in optic nerve hypoplasia Sacrum in sacral agenesis Facial muscle in asymmetric crying facies Thumb from birth Lungs, often as a result of oligohydramnios during gestation or the existence of congenital diaphragmatic hernia Small bowel in coeliac disease Fingers and ears in harlequin-type ichthyosis Mandible in congenital hypothyroidism |
Stratus VOS | Stratus VOS (Virtual Operating System) is a proprietary operating system running on Stratus Technologies fault-tolerant computer systems. VOS is available on Stratus's ftServer and Continuum platforms. VOS customers use it to support high-volume transaction processing applications which require continuous availability. VOS is notable for being one of the few operating systems which run on fully lockstepped hardware.
During the 1980s, an IBM version of Stratus VOS existed and was called the System/88 Operating System. |
Transepithelial potential difference | Transepithelial potential difference (TEPD) is the voltage across an epithelium, and is the sum of the membrane potentials for the outer and inner cell membranes. |
Koek-en-zopie | Koek-en-zopie (roughly translated as "cake-and-drinks" or "cake-and-eggnog") is a Dutch term that is used to denote the food and drink sold on the ice during periods of ice skating. |
Chewing tobacco | Chewing tobacco is a type of smokeless tobacco product that is placed between the cheek and lower gum to draw out its flavor. It consists of coarsely chopped aged tobacco that is flavored and often sweetened; it is not ground fine like dipping tobacco. Unwanted juices are then spat. |
Brownian surface | A Brownian surface is a fractal surface generated via a fractal elevation function.The Brownian surface is named after Brownian motion. |
Singing Valentines | Singing Valentines is the name for a fundraising program that is popular with barbershop choruses in the U.S., Canada and Australia.
The delivery of Singing Valentines is usually done by a barbershop quartet from a chapter affiliated with the three major International barbershop societies: Barbershop Harmony Society Sweet Adelines International Harmony, IncorporatedNote that this is not really a variation on the singing telegram, since the message detail is not dictated by the sender.
Rather, quartets usually deliver a canned package of one or two barbershop songs with a personalized card and either roses or chocolates. |
Digital topology | Digital topology deals with properties and features of two-dimensional (2D) or three-dimensional (3D) digital images that correspond to topological properties (e.g., connectedness) or topological features (e.g., boundaries) of objects.
Concepts and results of digital topology are used to specify and justify important (low-level) image analysis algorithms, including algorithms for thinning, border or surface tracing, counting of components or tunnels, or region-filling. |
Guy (sailing) | A guy (probably from Dutch gei, "brail") is a line (rope) attached to and intended to control the end of a spar on a sailboat. On a modern sloop-rigged sailboat with a symmetric spinnaker, the spinnaker pole is the spar most commonly controlled by one or more guys. |
CCDC184 | Coiled-coil domain-containing 184 (CCDC184) is a protein which, in humans, is encoded by the CCDC184 gene |
Scarab Research | Scarab Research is a research and development company specialized in recommender systems and machine learning. |
Archaeology, Anthropology, and Interstellar Communication | Archaeology, Anthropology, and Interstellar Communication is a 2014 collection of essays edited by Douglas Vakoch and published by NASA. The book is focused on the role that the humanities and social sciences, in particular anthropology and archaeology, play in the search for extraterrestrial intelligence (SETI). The seventeen essays are gathered into four sections, which respectively explore the history of SETI as a field; archaeological comparisons for human-alien communication, such as the difficulties of translating ancient languages; the inferential gap between humans and aliens, and the consequences this would have for communication and trade; and the potential nature of alien intelligences. |
Water clock | A water clock or clepsydra (from Ancient Greek κλεψύδρα (klepsúdra) 'pipette, water clock'; from κλέπτω (kléptō) 'to steal', and ὕδωρ (hydor) 'water'; lit. 'water thief') is a timepiece by which time is measured by the regulated flow of liquid into (inflow type) or out from (outflow type) a vessel, and where the amount is then measured. |
Standard Reference Method | The Standard Reference Method or SRM is one of several systems modern brewers use to specify beer color. Determination of the SRM value involves measuring the attenuation of light of a particular wavelength (430 nm) in passing through 1 cm of the beer, expressing the attenuation as an absorption and scaling the absorption by a constant (12.7 for SRM; 25 for EBC). The SRM (or EBC) number represents a single point in the absorption spectrum of beer. As such it cannot convey full color information which would require 81 points, but it does remarkably well in this regard (it conveys 92% of spectral information) even when fruit beers are considered. Auxiliary "deviation coefficients" (see Augmented SRM below) can pick up the remainder and are necessary for fruit beers and when subtle color differences in malt beers are to be characterized. |
LifeSaver bottle | The LifeSaver bottle is a portable water purification device. The bottle filters out objects larger than 15 nanometres. |
XY problem | The XY problem is a communication problem encountered in help desk, technical support, software engineering, or customer service situations where the question is about an end user's attempted solution (Y) rather than the root problem itself (X).The XY problem obscures the real issues and may even introduce secondary problems that lead to miscommunication, resource mismanagement, and sub-par solutions. The solution for the support personnel is to ask probing questions as to why the information is needed in order to identify the root problem X and redirect the end user away from an unproductive path of inquiry. |
In-memory database | An in-memory database (IMDB, or main memory database system (MMDB) or memory resident database) is a database management system that primarily relies on main memory for computer data storage. It is contrasted with database management systems that employ a disk storage mechanism. In-memory databases are faster than disk-optimized databases because disk access is slower than memory access and the internal optimization algorithms are simpler and execute fewer CPU instructions. Accessing data in memory eliminates seek time when querying the data, which provides faster and more predictable performance than disk.Applications where response time is critical, such as those running telecommunications network equipment and mobile advertising networks, often use main-memory databases. IMDBs have gained much traction, especially in the data analytics space, starting in the mid-2000s – mainly due to multi-core processors that can address large memory and due to less expensive RAM.A potential technical hurdle with in-memory data storage is the volatility of RAM. Specifically in the event of a power loss, intentional or otherwise, data stored in volatile RAM is lost. With the introduction of non-volatile random-access memory technology, in-memory databases will be able to run at full speed and maintain data in the event of power failure. |
Osteoid | In histology, osteoid is the unmineralized, organic portion of the bone matrix that forms prior to the maturation of bone tissue. Osteoblasts begin the process of forming bone tissue by secreting the osteoid as several specific proteins. When the osteoid becomes mineralized, it and the adjacent bone cells have developed into new bone tissue.
Osteoid makes up about fifty percent of bone volume and forty percent of bone weight. It is composed of fibers and ground substance. The predominant type of fiber is type I collagen and comprises ninety percent of the osteoid. The ground substance is mostly made up of chondroitin sulfate and osteocalcin. |
Thermodynamic relations across normal shocks | "Normal shocks" are a fundamental type of shock wave. The waves, which are perpendicular to the flow, are called "normal" shocks. Normal shocks only happen when the flow is supersonic. At those speeds, no obstacle is identified before the speed of sound which makes the molecule return after sensing the obstacle. While returning, the molecule becomes coalescent at certain point. This thin film of molecules act as normal shocks. |
Light gap | In ecology, a light gap is a break in forest canopy or similar barrier that allows young plants to grow where they would be otherwise inhibited by the lack of light reaching the seedbed. Light gaps form predominantly when a tree falls, and thus produces an opening in the forest canopy. Light gaps are important for maintaining diversity in species-rich ecosystems. |
Phonetic environment | In phonetics and linguistics, the phonetic environment of a given instance of a speech sound (or "phone") consists of the other phones adjacent to and surrounding it. The phonetic environment of a phone can sometimes determine the allophonic or phonemic qualities of a sound in a given language. |
Billet | A billet is a living-quarters to which a soldier is assigned to sleep. Historically, a billet was a private dwelling that was required to accept the soldier.
Soldiers are generally billeted in barracks or garrisons when not on combat duty, although in some armies soldiers with families are permitted to maintain a home off-post. Used for a building, the term billet is more commonly used in British English; United States standard terms are quarters, barracks, Single (Soldier) Housing or Family Housing. |
ATV Offroad Fury 4 | ATV Offroad Fury 4 is a racing video game developed by Climax Racing and published by Sony Computer Entertainment for PlayStation 2. It was released on October 31, 2006 in North America, on March 27, 2008 in Australia, and one day later in Europe. |
Event tree | An event tree is an inductive analytical diagram in which an event is analyzed using Boolean logic to examine a chronological series of subsequent events or consequences. For example, event tree analysis is a major component of nuclear reactor safety engineering.An event tree displays sequence progression, sequence end states and sequence-specific dependencies across time. |
Spectral invariants | In symplectic geometry, the spectral invariants are invariants defined for the group of Hamiltonian diffeomorphisms of a symplectic manifold, which is closed related to Floer theory and Hofer geometry. |
Panoramic photography | Panoramic photography is a technique of photography, using specialized equipment or software, that captures images with horizontally elongated fields of view. It is sometimes known as wide format photography. The term has also been applied to a photograph that is cropped to a relatively wide aspect ratio, like the familiar letterbox format in wide-screen video. |
Coprostane | Coprostane, also known as 5β-cholestane, is a steroid and a parent compound of a variety of steroid derivatives, such as ecdysone and coprostanol. |
Dick (slang) | Dick is a common English slang word for the human penis. It is also used by extension for a variety of slang purposes, generally considered vulgar, including: as a verb to describe sexual activity; and as a pejorative term for individuals who are considered to be rude, abrasive, inconsiderate, or otherwise contemptible. In this context, it can be used interchangeably with jerk, and can also be used as a verb to describe rude or deceitful actions. Variants include dickhead, which literally refers to the glans. The offensiveness of the word dick is complicated by the continued use of the word in inoffensive contexts, including as both a given name (often a nickname for Richard) and a surname, the popular British dessert spotted dick, the classic novel Moby-Dick, the Dick and Jane series of children's books, and the American retailer Dick's Sporting Goods. Uses such as these have provided a basis for comedy writers to exploit this juxtaposition through double entendre. |
Measurement tower | A measurement tower or measurement mast, also known as meteorological tower or meteorological mast (met tower or met mast), is a free standing tower or a removed mast, which carries measuring instruments with meteorological instruments, such as thermometers and instruments to measure wind speed. Measurement towers are an essential component of rocket launching sites, since one must know exact wind conditions for an execution of a rocket launch. Met masts are crucial in the development of wind farms, as precise knowledge of the wind speed is necessary to know how much energy will be produced, and whether the turbines will survive on the site. Measurement towers are also used in other contexts, for instance near nuclear power stations, and by ASOS stations. |
BACH2 | Transcription regulator protein BACH2 (broad complex-tramtrack-bric a brac and Cap'n'collar homology 2) is a protein that in humans is encoded by the BACH2 gene. It contains a BTB/POZ domain at its N-terminus which forms a disulphide-linked dimer and a bZip_Maf domain at the C-terminus. |

Palatini identity | In general relativity and tensor calculus, the Palatini identity is δRσν=∇ρδΓνσρ−∇νδΓρσρ, where δΓνσρ denotes the variation of Christoffel symbols and ∇ρ indicates covariant differentiation.The "same" identity holds for the Lie derivative LξRσν . In fact, one has LξRσν=∇ρ(LξΓνσρ)−∇ν(LξΓρσρ), where ξ=ξρ∂ρ denotes any vector field on the spacetime manifold M |
Affection (linguistics) | Affection (also known as vowel affection, infection or vowel mutation), in the linguistics of the Celtic languages, is the change in the quality of a vowel under the influence of the vowel of the following final syllable.
It is a type of anticipatory (or regressive) assimilation at a distance. The vowel that triggers the change was later normally lost. Some grammatical suffixes cause i-affection. In Welsh, gair "word" and -iadur "device suffix" yield geiriadur "dictionary", with -ai- in gair becoming -ei-. |
Lattice of subgroups | In mathematics, the lattice of subgroups of a group G is the lattice whose elements are the subgroups of G , with the partial order relation being set inclusion.
In this lattice, the join of two subgroups is the subgroup generated by their union, and the meet of two subgroups is their intersection. |
Parable | A parable is a succinct, didactic story, in prose or verse, that illustrates one or more instructive lessons or principles. It differs from a fable in that fables employ animals, plants, inanimate objects, or forces of nature as characters, whereas parables have human characters. A parable is a type of metaphorical analogy.Some scholars of the canonical gospels and the New Testament apply the term "parable" only to the parables of Jesus, although that is not a common restriction of the term. Parables such as the parable of the Prodigal Son are important to Jesus's teaching method. |
Hoeffding's inequality | In probability theory, Hoeffding's inequality provides an upper bound on the probability that the sum of bounded independent random variables deviates from its expected value by more than a certain amount. Hoeffding's inequality was proven by Wassily Hoeffding in 1963.Hoeffding's inequality is a special case of the Azuma–Hoeffding inequality and McDiarmid's inequality. It is similar to the Chernoff bound, but tends to be less sharp, in particular when the variance of the random variables is small. It is similar to, but incomparable with, one of Bernstein's inequalities. |
Amnesty bin | An amnesty bin or amnesty box is a receptacle into which items can be placed without incurring consequences related to those items. Amnesty bins have been used for various items, including drugs, weapons, fruit, invasive species, and animals. A version of an amnesty bin is also used at Amazon warehouses for damaged items. |
Entheogen | Entheogens are psychoactive substances that induce alterations in perception, mood, consciousness, cognition, or behavior for the purposes of engendering spiritual development or otherwise in sacred contexts. The anthropological study has established that entheogens are used for religious, magical, shamanic, or spiritual purposes in many parts of the world. Entheogens have traditionally been used to supplement many diverse practices geared towards achieving transcendence, including divination, meditation, yoga, sensory deprivation, healings, asceticism, prayer, trance, rituals, chanting, imitation of sounds, hymns like peyote songs, drumming, and ecstatic dance. The psychedelic experience is often compared to non-ordinary forms of consciousness such as those experienced in meditation, near-death experiences, and mystical experiences. Ego dissolution is often described as a key feature of the psychedelic experience. |
BeIA | BeIA, or BeOS for Internet Appliances, was a minimized version of Be Inc.'s BeOS operating system for embedded systems. |
Pleaching | Pleaching or plashing is a technique of interweaving living and dead branches through a hedge creating a fence, hedge or lattices. Trees are planted in lines, and the branches are woven together to strengthen and fill any weak spots until the hedge thickens. Branches in close contact may grow together, due to a natural phenomenon called inosculation, a natural graft. Pleach also means weaving of thin, whippy stems of trees to form a basketry effect. |
Colpocleisis | Colpocleisis is a procedure involving closure of the vagina. |
Vinyl composition tile | Vinyl composition tile (VCT) is a finished flooring material used primarily in commercial and institutional applications. Modern vinyl floor tiles and sheet flooring and versions of those products sold since the early 1980s are composed of colored polyvinyl chloride (PVC) chips formed into solid sheets of varying thicknesses (1⁄8 in or 3.2 mm is most common) by heat and pressure. Floor tiles are cut into modular shapes such 12-by-12-inch (300 mm × 300 mm) squares or 12-by-24-inch (300 mm × 610 mm) rectangles. In installation the floor tiles or sheet flooring are applied to a smooth, leveled sub-floor using a specially formulated vinyl adhesive or tile mastic that remains pliable. In commercial applications some tiles are typically waxed and buffed using special materials and equipment. |
End system | In networking jargon, a computer, phone, or internet of things device connected to a computer network is sometimes referred to as an end system or end station, because it sits at the edge of the network. The end user directly interacts with an end system that provides information or services.End systems that are connected to the Internet are also referred to as internet hosts; this is because they host (run) internet applications such as a web browser or an email retrieval program. The Internet's end systems include some computers with which the end user does not directly interact. These include mail servers, web servers, or database servers. With the emergence of the internet of things, household items (such as toasters and refrigerators) as well as portable, handheld computers and digital cameras are all being connected to the internet as end systems. |
ONIOM | The ONIOM (short for 'Our own N-layered Integrated molecular Orbital and Molecular mechanics') method is a computational approach developed by Morokuma and co-workers. ONIOM is a hybrid method that enables different ab initio, semi-empirical, or molecular mechanics methods to be applied to different parts of a molecule/system in combination to produce reliable geometry and energy at reduced computational cost.The ONIOM computational approach has been found to be particularly useful for modeling biomolecular systems as well as for transition metal complexes and catalysts. |
Liljequist parhelion | A Liljequist parhelion is a rare halo, an optical phenomenon in the form of a brightened spot on the parhelic circle approximately 150–160° from the sun; i.e., between the position of the 120° parhelion and the anthelion. |
Screen scroll centrifuge | Screen/Scroll centrifuge is a filtering or screen centrifuge which is also known as worm screen or conveyor discharge centrifuge. This centrifuge was first introduced in the midst of 19th century. After developing new technologies over the decades, it is now one of the widely used processes in many industries for the separation of crystalline, granular or fibrous materials from a solid-liquid mixture. Also, this process is considered to dry the solid material. This process has been some of the most frequently seen within, especially, coal preparation industry. Moreover, it can be found in other industries such as chemical, environmental, food and other mining fields. |
DelNS1-2019-nCoV-RBD-OPT | DelNS1-2019-nCoV-RBD-OPT is a COVID-19 vaccine candidate developed by Beijing Wantai Biological, Xiamen University and the University of Hong Kong.On 14 December 2022, the vaccine was listed by the National Health Commission of China as a secondary booster dose option for people who have completed their third doses of inactivated COVID-19 vaccines for 6 months or longer. |

Oil purification | Oil purification (transformer, turbine, industrial, etc.) removes oil contaminants in order to prolong oil service life. |
Baseball metaphors for sex | In American slang, baseball metaphors for sex are often used as euphemisms for the degree of physical intimacy achieved in sexual encounters or relationships. In the metaphor, first prevalent in the aftermath of World War II, sexual activities are described as if they are actions in a game of baseball. Baseball has also served as the context for metaphors about sexual roles and identity. |
Classical XY model | The classical XY model (sometimes also called classical rotor (rotator) model or O(2) model) is a lattice model of statistical mechanics. In general, the XY model can be seen as a specialization of Stanley's n-vector model for n = 2. |
Core ontology | In philosophy, a core ontology is a basic and minimal ontology consisting only of the minimal concepts required to understand the other concepts. It must be based on a core glossary in some human language so humans can comprehend the concepts and distinctions made. Each natural language tends to rely on its own conceptual metaphor structure, and so tends to have its own core ontology (according to W. V. Quine). It could be said also to represent the moral core of a human linguistic culture, and to self-correct so as to better represent core cultural ideas. |
PsbNH RNA motif | The psbNH RNA motif describes a class of RNA molecules that have a conserved secondary structure. psbNH RNAs are always found between psbH and psbH genes, both of which are involved in the cyanobacterial photosystem II are transcribed in opposite orientations. It is unknown whether the biological psbNH RNA is as depicted in the diagram, or whether its reverse complement is the transcribed molecule. In either case, the RNA would be in the 5' untranslated region of a gene, either psbN or psbH, and likely a cis-regulatory element. |
