Pram or PRAM may refer to:
Anaxonic neuron
An anaxonic neuron is a type of neuron where there is no axon or it cannot be differentiated from the dendrites. Being loyal to the etymology of anaxonic there are two types of anaxonic neurons in the human nervous system, the undifferentiated anaxonic neuron where the axon cannot be differentiated from the dendrites, and the unipolar brush cell (UBC), that has no axon and only a dendritic arbour.
APOA5
Apolipoprotein A-V is a protein that in humans is encoded by the APOA5 gene on chromosome 11. It is significantly expressed in liver. The protein encoded by this gene is an apolipoprotein and an important determinant of plasma triglyceride levels, a major risk factor for coronary artery disease. It is a component of several lipoprotein fractions including VLDL, HDL, chylomicrons. It is believed that apoA-V affects lipoprotein metabolism by interacting with LDL-R gene family receptors. Considering its association with lipoprotein levels, APOA5 is implicated in metabolic syndrome. The APOA5 gene also contains one of 27 SNPs associated with increased risk of coronary artery disease.
Arbitration inter-frame spacing
Arbitration inter-frame spacing (AIFS), in wireless LAN communications, is a method of prioritizing one Access Category (AC) over the other, such as giving voice or video priority over email. AIFS functions by shortening or expanding the period a wireless node has to wait before it is allowed to transmit its next frame. A shorter AIFS period means a message has a higher probability of being transmitted with low latency, which is particularly important for delay-critical data such as voice or streaming video.
Dousing
Dousing is the practice of making something or someone wet by throwing liquid over them, e.g., by pouring water, generally cold, over oneself. A related practice is ice swimming. Some consider cold water dousing to be a form of asceticism.
Constraint graph (layout)
In some tasks of integrated circuit layout design a necessity arises to optimize placement of non-overlapping objects in the plane. In general this problem is extremely hard, and to tackle it with computer algorithms, certain assumptions are made about admissible placements and about operations allowed in placement modifications. Constraint graphs capture the restrictions of relative movements of the objects placed in the plane. These graphs, while sharing common idea, have different definition, depending on a particular design task or its model.
CAT RNA-binding domain
In molecular biology, the CAT RNA-binding domain (Co-AntiTerminator RNA-binding domain) is a protein domain found at the amino terminus of a family of transcriptional antiterminator proteins. This domain forms a dimer in the crystal structure. Transcriptional antiterminators of the BglG/SacY family are regulatory proteins that mediate the induction of sugar metabolizing operons in Gram-positive and Gram-negative bacteria. Upon activation, these proteins bind to specific targets in nascent mRNAs, thereby preventing abortive dissociation of the RNA polymerase from the DNA template.
The Science of Survival
The Science Museum is a major museum on Exhibition Road in South Kensington, London. It was founded in 1857 and is one of the city's major tourist attractions, attracting 3.3 million visitors annually in 2019.Like other publicly funded national museums in the United Kingdom, the Science Museum does not charge visitors for admission, although visitors are requested to make a donation if they are able. Temporary exhibitions may incur an admission fee.
Biochemistry of body odor
The biochemistry of body odor pertains to the chemical compounds in the body responsible for body odor and their kinetics.
Neber rearrangement
The Neber rearrangement is an organic reaction in which a ketoxime is converted into an alpha-aminoketone via a rearrangement reaction. The oxime is first converted to an O-sulfonate, for example a tosylate by reaction with tosyl chloride. Added base forms a carbanion which displaces the tosylate group in a nucleophilic displacement to an azirine and added water subsequently hydrolyses it to the aminoketone. The Beckmann rearrangement is a side reaction.
Bistability
In a dynamical system, bistability means the system has two stable equilibrium states. A bistable structure can be resting in either of two states. An example of a mechanical device which is bistable is a light switch. The switch lever is designed to rest in the "on" or "off" position, but not between the two. Bistable behavior can occur in mechanical linkages, electronic circuits, nonlinear optical systems, chemical reactions, and physiological and biological systems.
Spatial-numerical association of response codes
The spatial-numerical association of response codes (SNARC) is an example of the spatial organisation of magnitude information. Put simply, when presented with smaller numbers (0 to 4), people tend to respond faster if those stimuli are associated with the left extrapersonal hemiside of their perceived surroundings; when presented with larger numbers (6 to 9), people respond faster if those stimuli are instead associated with the right extrapersonal hemiside of their perceived surroundings. The SNARC effect is this automatic association that occurs between the location of the response hand and the semantic magnitude of a modality-independent number.Even for tasks in which magnitude is irrelevant, like parity judgement or phoneme detection, larger numbers are faster responded to with the right response key while smaller numbers are faster responded to with the left. This also occurs when the hands are crossed, with the right hand activating the left response key and vice versa. The explanation given by Dehaene and colleagues is that the magnitude of a number on an oriented mental number line is automatically activated. The mental number line is assumed to be oriented from left to right in populations with a left-to-right writing system (e.g. English), and oriented from right to left in populations with a right-to-left writing system (e.g. Iranian)
MIR1271
MicroRNA 1271 is a microRNA that in humans is encoded by the MIR1271 gene.
Oxygen toxicity
Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O2) at increased partial pressures. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes. Historically, the central nervous system condition was called the Paul Bert effect, and the pulmonary condition the Lorrain Smith effect, after the researchers who pioneered the discoveries and descriptions in the late 19th century. Oxygen toxicity is a concern for underwater divers, those on high concentrations of supplemental oxygen, and those undergoing hyperbaric oxygen therapy.
Twenty-One Card Trick
The Twenty-One Card Trick, also known as the 11th card trick or three column trick, is a simple self-working card trick that uses basic mathematics to reveal the user's selected card.
Intertrochanteric line
The intertrochanteric line is a line upon the anterior aspect of the proximal end of the femur, extending between the lesser trochanter and the greater trochanter. It is a rough, variable ridge.
ResearcherID
ResearcherID is an identifying system for scientific authors. The system was introduced in January 2008 by Thomson Reuters Corporation.
Plug (horticulture)
Plugs in horticulture are small-sized seedlings grown in seed trays filled with potting soil. This type of plug is used for commercially raising vegetables and bedding plants. Similarly plugs may also refer to small sections of lawn grass sod. After being planted, lawn grass may somewhat spread over an adjacent area.
Java concurrency
The Java programming language and the Java virtual machine (JVM) is designed to support concurrent programming. All execution takes place in the context of threads. Objects and resources can be accessed by many separate threads. Each thread has its own path of execution, but can potentially access any object in the program. The programmer must ensure read and write access to objects is properly coordinated (or "synchronized") between threads. Thread synchronization ensures that objects are modified by only one thread at a time and prevents threads from accessing partially updated objects during modification by another thread. The Java language has built-in constructs to support this coordination.
Polysaccharide–protein conjugate
Polysaccharide–protein conjugates may have better solubility and stability, reduced immunogenicity, prolonged circulation time, and enhanced targeting ability compared to native protein. They are promising alternatives to PEG–protein drugs, in which non-biodegradable high molecular weight PEG causes health concerns.
Ecology and Evolutionary Biology
Ecology and evolutionary biology is an interdisciplinary field of study concerning interactions between organisms and their ever-changing environment, including perspectives from both evolutionary biology and ecology. This field of study includes topics such as the way organisms respond and evolve, as well as the relationships among animals, plants, and micro-organisms, when their habitats change. Ecology and evolutionary biology is a broad field of study that covers various ranges of ages and scales, which can also help us to comprehend human impacts on the global ecosystem and find measures to achieve more sustainable development.
Subglacial stream
Subglacial streams are conduits of glacial meltwater that flow at the base of glaciers and ice caps. Meltwater from the glacial surface travels downward throughout the glacier, forming an englacial drainage system consisting of a network of passages that eventually reach the bedrock below, where they form subglacial streams. Subglacial streams form a system of tunnels and interlinked cavities and conduits, with water flowing under extreme pressures from the ice above; as a result, flow direction is determined by the pressure gradient from the ice and the topography of the bed rather than gravity. Subglacial streams form a dynamic system that is responsive to changing conditions, and the system can change significantly in response to seasonal variation in meltwater and temperature. Water from subglacial streams is routed towards the glacial terminus, where it exits the glacier. Discharge from subglacial streams can have a significant impact on local, and in some cases global, environmental and geological conditions. Sediments, nutrients, and organic matter contained in the meltwater can all influence downstream and marine conditions. Climate change may have a significant impact on subglacial stream systems, increasing the volume of meltwater entering subglacial drainage systems and influencing their hydrology.
Discourse grammar
Discourse Grammar (DG) is a grammatical framework that grew out of the analysis of spoken and written linguistic discourse on the one hand, and of work on parenthetical expressions, including Simon C. Dik's study of extra-clausal constituents, on the other. Initiated by Gunther Kaltenböck, Bernd Heine and Tania Kuteva, the framework is based on the distinction between two organizing principles of grammar where one concerns the structure of sentences and the other the linguistic organization beyond the sentence.
Apoplexy
Apoplexy (from Ancient Greek ἀποπληξία (apoplexia) 'a striking away') is rupture of an internal organ and the accompanying symptoms. The term formerly referred to what is now called a hemorrhagic stroke, which is the result of a ruptured blood vessel in the brain. Today health care professionals do not use the term, but instead specify the anatomic location of the bleeding, such as cerebral, ovarian or pituitary.Informally or metaphorically, the term apoplexy is associated with being furious, especially as "apoplectic".
Retained placenta
Retained placenta is a condition in which all or part of the placenta or membranes remain in the uterus during the third stage of labour. Retained placenta can be broadly divided into: failed separation of the placenta from the uterine lining placenta separated from the uterine lining but retained within the uterusA retained placenta is commonly a cause of postpartum haemorrhage, both primary and secondary.Retained placenta is generally defined as a placenta that has not undergone placental expulsion within 30 minutes of the baby’s birth where the third stage of labor has been managed actively.
Spot delivery
Spot delivery (or spot financing) is a term used in the automobile industry that means delivering a vehicle to a buyer prior to financing on the vehicle being completed. Spot delivery is used by dealerships on the weekend or after bank hours to be able to deliver a vehicle when a final approval cannot be received from a bank. This method of delivery is regulated by many states in the U.S., and is sometimes referred to as a "Yo-Yo sale" or "Yo-Yo Financing."During a spot delivery, many consumers believe that the deal is final when in fact it is not. Signed agreements allow the dealership the right to take the car back or renegotiate the agreement if it cannot obtain financing within a specific amount of time.
Common Electrical I/O
The Common Electrical I/O (CEI) refers to a series of influential Interoperability Agreements (IAs) that have been published by the Optical Internetworking Forum (OIF). CEI defines the electrical and jitter requirements for 3.125, 6, 11, 25-28, and 56 Gbit/s electrical interfaces.
Metabolic trapping
Metabolic trapping refers to a localization mechanism of synthesized radiocompounds in the human body. It can be defined as the intracellular accumulation of a radioactive tracer based on the relative metabolic activity of the body's tissues. It is a basic principle of the design of radiopharmaceuticals as metabolic probes for functional studies or tumor location.Metabolic trapping is the mechanism underlying the (PET) scan, an effective tool for detecting tumors, as there is a greater uptake of the target molecule by tumor tissue than by normal tissue.
Response surface methodology
In statistics, response surface methodology (RSM) explores the relationships between several explanatory variables and one or more response variables. The method was introduced by George E. P. Box and K. B. Wilson in 1951. The main idea of RSM is to use a sequence of designed experiments to obtain an optimal response. Box and Wilson suggest using a second-degree polynomial model to do this. They acknowledge that this model is only an approximation, but they use it because such a model is easy to estimate and apply, even when little is known about the process.
Ross Mine Formation
The Ross Mine Formation is a geologic formation in Texas. It preserves fossils dating back to the Permian period.
V particle
In particle physics, V was a generic name for heavy, unstable subatomic particles that decay into a pair of particles, thereby producing a characteristic letter V in a bubble chamber or other particle detector. Such particles were first detected in cosmic ray interactions in the atmosphere in the late 1940s and were first produced using the Cosmotron particle accelerator at Brookhaven National Laboratory in the 1950s. Since all such particles have now been identified and given specific names, for instance Kaons or Sigma baryons, this term has fallen into disuse.
Sherwood number
The Sherwood number (Sh) (also called the mass transfer Nusselt number) is a dimensionless number used in mass-transfer operation. It represents the ratio of the convective mass transfer to the rate of diffusive mass transport, and is named in honor of Thomas Kilgore Sherwood.
Total harmonic distortion
The total harmonic distortion (THD or THDi) is a measurement of the harmonic distortion present in a signal and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. Distortion factor, a closely related term, is sometimes used as a synonym. In audio systems, lower distortion means the components in a loudspeaker, amplifier or microphone or other equipment produce a more accurate reproduction of an audio recording.
Cabot rings
Cabot rings are thin, red-violet staining, threadlike strands in the shape of a loop or figure-8 that are found on rare occasions in red blood cells (erythrocytes). They are believed to be microtubules that are remnants from a mitotic spindle, and their presence indicates an abnormality in the production of red blood cells. Cabot Rings, considerably rare findings, when present are found in the cytoplasm of red blood cells and in most cases, are caused by defects of erythrocytic production and are not commonly found in the blood circulating throughout the body.
Line–line intersection
In Euclidean geometry, the intersection of a line and a line can be the empty set, a point, or another line. Distinguishing these cases and finding the intersection have uses, for example, in computer graphics, motion planning, and collision detection.
Hill bomb
A hill bomb is a maneuver in skateboarding in which a rider rides down a big hill. The trick is noted for its particular danger and, sometimes, grace.
Automation Studio
Automation Studio is a circuit design, simulation and project documentation software for fluid power systems and electrical projects conceived by Famic Technologies Inc.. It is used for CAD, maintenance, and training purposes. Mainly used by engineers, trainers, and service and maintenance personnel. Automation Studio can be applied in the design, training and troubleshooting of hydraulics, pneumatics, HMI, and electrical control systems.Two versions of the software exist: Automation Studio Professional Automation Studio EducationalThe educational version of Automation Studio is a limited features version used by engineering and technical schools to train students who are future engineers or technicians. The software is designed for schools that teach technical subjects such as industrial technologies, mechatronics, electromechanical technologies, electrical & electronics, automation, and maintenance. Modeling and simulation are used to illustrate theoretical aspects.
Radio spectrum scope
The radio spectrum scope (also radio panoramic receiver, panoramic adapter, pan receiver, pan adapter, panadapter, panoramic radio spectroscope, panoramoscope, panalyzor and band scope) was invented by Marcel Wallace - and measures and shows the magnitude of an input signal versus frequency within one or more radio bands - e.g. shortwave bands. A spectrum scope is normally a lot cheaper than a spectrum analyzer, because the aim is not high quality frequency resolution - nor high quality signal strength measurements.
Journal of the IEST
The Journal of the IEST is a peer-reviewed scientific journal and the official publication of the Institute of Environmental Sciences and Technology (IEST). It covers research on simulation, testing, modeling, control, and the teaching of the environmental sciences and technologies. The journal was established in 1958 as the Journal of Environmental Engineering. In October 1959, it was renamed Journal of Environmental Sciences and obtained its current title in 1998.
X-Win32
In computing, X-Win32 is a proprietary implementation of the X Window System for Microsoft Windows, produced by StarNet Communications. It is based on X11R7.4. X- Win32 allows remote display of UNIX windows on Windows machines in a normal window alongside the other Windows applications
Abortion doping
Abortion doping is a rumoured practice of purposely inducing pregnancy specifically for athletic performance-enhancing benefits, and then aborting the pregnancy. Rumours and allegations began during international sporting events in the mid-twentieth century, and a number of doctors and scientists have repeated claims about it, but it remains unproven, and is often regarded as a myth.
Anterior cruciate ligament
The anterior cruciate ligament (ACL) is one of a pair of cruciate ligaments (the other being the posterior cruciate ligament) in the human knee. The two ligaments are also called "cruciform" ligaments, as they are arranged in a crossed formation. In the quadruped stifle joint (analogous to the knee), based on its anatomical position, it is also referred to as the cranial cruciate ligament. The term cruciate translates to cross. This name is fitting because the ACL crosses the posterior cruciate ligament to form an “X”. It is composed of strong, fibrous material and assists in controlling excessive motion. This is done by limiting mobility of the joint. The anterior cruciate ligament is one of the four main ligaments of the knee, providing 85% of the restraining force to anterior tibial displacement at 30 and 90° of knee flexion. The ACL is the most injured ligament of the four located in the knee.
ERCC1
DNA excision repair protein ERCC-1 is a protein that in humans is encoded by the ERCC1 gene. Together with ERCC4, ERCC1 forms the ERCC1-XPF enzyme complex that participates in DNA repair and DNA recombination.Many aspects of these two gene products are described together here because they are partners during DNA repair. The ERCC1-XPF nuclease is an essential activity in the pathway of DNA nucleotide excision repair (NER). The ERCC1-XPF nuclease also functions in pathways to repair double-strand breaks in DNA, and in the repair of “crosslink” damage that harmfully links the two DNA strands.
Nihon Kohden
Nihon Kohden Corporation (日本光電工業株式会社, Nihon Kōdenkōgyō Kabushiki-gaisha) is a Tokyo-based leading manufacturer, developer and distributor of medical electronic equipment, which include EEGs, EMG measuring systems, ECGs, patient monitors, Invasive and Non-Invasive Ventilators, Defibrillators, AEDs and clinical information systems, with subsidiaries in the U.S., Europe and Asia. The company's products are now used in more than 120 countries, and it is the largest supplier of EEG products worldwide.In 1972, Takuo Aoyagi, a researcher at the company, invented and patented the basic principles of pulse oximetry. Two years later he developed the world's first pulse oximeter, the OLV-5100, which has helped improve patient safety during anaesthesia.
Bromochlorofluoromethane
Bromochlorofluoromethane or fluorochlorobromomethane, is a chemical compound and trihalomethane derivative with the chemical formula CHBrClF. As one of the simplest possible stable chiral compounds, it is useful for fundamental research into this area of chemistry. However, its relative instability to hydrolysis, and lack of suitable functional groups, made separation of the enantiomers of bromochlorofluoromethane especially challenging, and this was not accomplished until almost a century after it was first synthesised, in March 2005, though it has now been done by a variety of methods. More recent research using bromochlorofluoromethane has focused on its potential use for experimental measurement of parity violation, a major unsolved problem in quantum physics.
Botanical prospecting for uranium
Botanical prospecting for uranium is a method of finding uranium deposits either by observation of plant life growing on the surface, or by geochemical analysis of plant material.
Obstetrical forceps
Obstetrical forceps are a medical instrument used in childbirth. Their use can serve as an alternative to the ventouse (vacuum extraction) method.
Bioorganic & Medicinal Chemistry Letters
Bioorganic & Medicinal Chemistry Letters is a scientific journal focusing on the results of research on the molecular structure of biological organisms and the interaction of biological targets with chemical agents. It is published by Elsevier, which also publishes Bioorganic & Medicinal Chemistry for longer works.
Encyclopedia of Life Support Systems
The Encyclopedia of Life Support Systems (EOLSS) is an integrated compendium of twenty one encyclopedias. The first Earth Summit of 1992, held in Rio de Janeiro, issued a document that is now famous as Agenda 21. This document refers to the Earth's life support systems, considering the whole of our planet as a grand intensive care unit that supports all forms of life (both natural and human-engineered systems).
Trailer light converter
A trailer light converter is an electrical component used for connecting the wiring of a trailer onto a towing vehicle.
Trinity Universe (setting)
The Trinity Universe (also called the Æon Continuum or the Æonverse) is the shared science fiction setting created by White Wolf Publishing. Its component game lines include: Adventure!, a pulp-action game set in 1924. Aberrant, a superpowers game set in the near-future (from 2008 to 2015). Trinity, a science fiction game where players take on the role of psions in the far future (from 2120 to 2122).
Square Pegs (Hong Kong TV series)
Square Pegs (Traditional Chinese: 戇夫成龍) was a Hong Kong television series 2003. The program's title is an abbreviated reference to the English idiomatic phrase "square peg in a round hole." The series was the runaway success of 2003, commanding a peak viewership of 46 points, approximately 3.5 million or roughly half of Hong Kong's population during the last week of its broadcast, and breaking TVB's ten-year ratings record. It also went on to win four awards for its two lead actors in the TVB 36th Anniversary Awards, and made both Roger Kwok and Jessica Hsuan household names in the territory.
People (Windows)
People is a contact management app and address book included in Microsoft's Windows 8 and 10. It allows a user to organize and link contacts from different email accounts. People has a unique graphical interface, unlike Windows Contacts' File Explorer-based interface, based on the Metro design language that had already been used for Outlook.com and the integrated online People service. In addition to being an address book, it provides a list of recent mail conversations with a selected contact. It used to also be a social media hub, in which users could integrate their social networking accounts (e.g. Twitter), but API changes in both Windows and social media services caused this functionality to break.People works with other Metro-style apps, but it has its own front-end interface and can be opened by end users. Unlike Windows Contacts, it does not currently allow users to import or export .pst files, vCard files, Windows Address Book files, or other files directly. Instead, it gathers contact information from email accounts the user has set up on other services in Windows, such as Mail and Calendar, Skype Preview, or the Xbox app. Changes, additions, and deletions made in the People app will be exported to the corresponding email accounts. Users can select which accounts should display contact info in People.
Maximum entropy thermodynamics
In physics, maximum entropy thermodynamics (colloquially, MaxEnt thermodynamics) views equilibrium thermodynamics and statistical mechanics as inference processes. More specifically, MaxEnt applies inference techniques rooted in Shannon information theory, Bayesian probability, and the principle of maximum entropy. These techniques are relevant to any situation requiring prediction from incomplete or insufficient data (e.g., image reconstruction, signal processing, spectral analysis, and inverse problems). MaxEnt thermodynamics began with two papers by Edwin T. Jaynes published in the 1957 Physical Review.
Saltzer and Schroeder's design principles
Saltzer and Schroeder's design principles are design principles enumerated by Jerome Saltzer and Michael Schroeder in their 1975 article The Protection of Information in Computer Systems, that from their experience are important for the design of secure software systems.
RExcel
RExcel is an add-in for Microsoft Excel. It allows access to the statistics package R from within Excel.
Exchange spring magnet
An exchange spring magnet is a magnetic material with high coercivity and high saturation properties derived from the exchange interaction between a hard magnetic material and a soft magnetic material, respectively. Coehoorn et al. were the first able to observe an actual exchange spring magnet. Exchange spring magnets are cheaper than many magnets containing rare earth/transition metals (RE-TM Magnets), as the hard phase of the magnet (which commonly comprises RE-TM material) can be less than 15% of the overall magnet by volume.
European Sleep Apnea Database
The European Sleep Apnea Database (ESADA) (also referred to with spelling European Sleep Apnoea Database and European Sleep Apnoea Cohort) is a collaboration between European sleep centres as part of the European Cooperation in Science and Technology (COST) Action B 26. The main contractor of the project is the Sahlgrenska Academy at Gothenburg University, Institute of Medicine, Department of Internal Medicine, and the co-ordinator is Jan Hedner, MD, PhD, Professor of Sleep Medicine.The book Clinical Genomics: Practical Applications for Adult Patient Care said ESADA was an example initiatives which afford an "excellent opportunity" for future collaborative research into genetic aspects of obstructive sleep apnea syndrome (OSAS). Both the European Respiratory Society and the European Sleep Research Society have noted the impact for research cooperative efforts of the database resource.
LTR retrotransposon
LTR retrotransposons are class I transposable element characterized by the presence of long terminal repeats (LTRs) directly flanking an internal coding region. As retrotransposons, they mobilize through reverse transcription of their mRNA and integration of the newly created cDNA into another location. Their mechanism of retrotransposition is shared with retroviruses, with the difference that most LTR-retrotransposons do not form infectious particles that leave the cells and therefore only replicate inside their genome of origin. Those that do (occasionally) form virus-like particles are classified under Ortervirales.
Errorless learning
Errorless learning was an instructional design introduced by psychologist Charles Ferster in the 1950s as part of his studies on what would make the most effective learning environment. B. F. Skinner was also influential in developing the technique, noting that, ...errors are not necessary for learning to occur. Errors are not a function of learning or vice versa nor are they blamed on the learner. Errors are a function of poor analysis of behavior, a poorly designed shaping program, moving too fast from step to step in the program, and the lack of the prerequisite behavior necessary for success in the program. Errorless learning can also be understood at a synaptic level, using the principle of Hebbian learning ("Neurons that fire together wire together").
Structural complexity theory
In computational complexity theory of computer science, the structural complexity theory or simply structural complexity is the study of complexity classes, rather than computational complexity of individual problems and algorithms. It involves the research of both internal structures of various complexity classes and the relations between different complexity classes.
Reproductive surgery
Reproductive surgery is surgery in the field of reproductive medicine. It can be used for contraception, e.g. in vasectomy, wherein the vasa deferentia of a male are severed, but is also used plentifully in assisted reproductive technology. Reproductive surgery is generally divided into three categories: surgery for infertility, in vitro fertilization, and fertility preservation.A reproductive surgeon is an obstetrician-gynecologist or urologist who specializes in reproductive surgery.Reproductive surgeries will be referred to based on biological sex, and terms such male and female will be used to denote to men and women respectively.
Head pressing
Head pressing is a veterinary condition characterized by pressing the head against a wall or pushing the face into a corner for no apparent reason. This condition is seen in dogs, cats, cows, horses, and goats. Head pressing is usually a sign of a neurological disorder, especially of the forebrain (e.g., prosencephalon disease), or of toxicity due to liver damage, such as portosystemic shunt and hepatic encephalopathy.It should be distinguished from bunting, which is a normal behavior found in healthy animals.

His research has resulted in five startups, of which four are healthcare-related.
Hyoscyamine/hexamethylenetetramine/phenyl salicylate/methylene blue/benzoic acid
Hyoscyamine/­hexamethylenetetramine/­phenyl salicylate/­methylene blue/­benzoic acid (trade names Methylphen, Prosed DS) is a drug combination. It is not safe or effective for any medical purpose.
Parallel I/O
Parallel I/O, in the context of a computer, means the performance of multiple input/output operations at the same time, for instance simultaneously outputs to storage devices and display devices. It is a fundamental feature of operating systems.One particular instance is parallel writing of data to disk; when file data is spread across multiple disks, for example in a RAID array, one can store multiple parts of the data at the same time, thereby achieving higher write speeds than with a single device.Other ways of parallel access to data include: Parallel Virtual File System, Lustre, GFS etc.
Corn whiskey
Corn whiskey is an American liquor made principally from corn. Distinct from the stereotypical American moonshine, in which sugar is normally added to the mash, corn whiskey uses a traditional mash process, and is subject to the tax and identity laws for alcohol under federal law.
Process calculus
In computer science, the process calculi (or process algebras) are a diverse family of related approaches for formally modelling concurrent systems. Process calculi provide a tool for the high-level description of interactions, communications, and synchronizations between a collection of independent agents or processes. They also provide algebraic laws that allow process descriptions to be manipulated and analyzed, and permit formal reasoning about equivalences between processes (e.g., using bisimulation). Leading examples of process calculi include CSP, CCS, ACP, and LOTOS. More recent additions to the family include the π-calculus, the ambient calculus, PEPA, the fusion calculus and the join-calculus.
Novikov ring
In mathematics, given an additive subgroup Γ⊂R , the Novikov ring Nov ⁡(Γ) of Γ is the subring of Z[[Γ]] consisting of formal sums ∑nγitγi such that γ1>γ2>⋯ and γi→−∞ . The notion was introduced by Sergei Novikov in the papers that initiated the generalization of Morse theory using a closed one-form instead of a function. The notion is used in quantum cohomology, among the others.
Lexical entrainment
Lexical entrainment is the phenomenon in conversational linguistics of the process of the subject adopting the reference terms of their interlocutor. In practice, it acts as a mechanism of the cooperative principle in which both parties to the conversation employ lexical entrainment as a progressive system to develop "conceptual pacts" (a working temporary conversational terminology) to ensure maximum clarity of reference in the communication between the parties; this process is necessary to overcome the ambiguity inherent in the multitude of synonyms that exist in language. Lexical entrainment arises by two cooperative mechanisms: Embedded corrections – a reference to the object implied by the context of the sentence, but with no explicit reference to the change in terminology Exposed corrections – an explicit reference to the change in terminology, possibly including a request to assign the referent a common term (e.g., "by 'girl', do you mean 'Jane'?")
Ceftaroline fosamil
Ceftaroline fosamil (INN) , brand name Teflaro in the US and Zinforo in Europe, is a cephalosporin antibiotic with anti-MRSA activity. Ceftaroline fosamil is a prodrug of ceftaroline. It is active against methicillin-resistant Staphylococcus aureus (MRSA) and other Gram-positive bacteria. It retains some activity of later-generation cephalosporins having broad-spectrum activity against Gram-negative bacteria, but its effectiveness is relatively much weaker. It is currently being investigated for community-acquired pneumonia and complicated skin and skin structure infection.Ceftaroline is being developed by Forest Laboratories, under a license from Takeda.
Facility information model
A facility information model is an information model of an individual facility that is integrated with data and documents about the facility. The facility can be any large facility that is designed, fabricated, constructed and installed, operated, maintained and modified; for example, a complete infrastructural network, a process plant, a building, a highway, a ship or an airplane.
Agricultural microbiology
Agricultural microbiology is a branch of microbiology dealing with plant-associated microbes and plant and animal diseases. It also deals with the microbiology of soil fertility, such as microbial degradation of organic matter and soil nutrient transformations.
Magnetization reversal by circularly polarized light
Discovered only as recently as 2006 by C.D. Stanciu and F. Hansteen and published in Physical Review Letters, this effect is generally called all-optical magnetization reversal. This magnetization reversal technique refers to a method of reversing magnetization in a magnet simply by circularly polarized light and where the magnetization direction is controlled by the light helicity. In particular, the direction of the angular momentum of the photons would set the magnetization direction without the need of an external magnetic field. In fact, this process could be seen as similar to magnetization reversal by spin injection (see also spintronics). The only difference is that now, the angular momentum is supplied by the circularly polarized photons instead of the polarized electrons.
Wolf hunting with dogs
Wolf hunting with dogs is a method of wolf hunting which relies on the use of hunting dogs. While any dog, especially a hound used for hunting wolves may be loosely termed a "wolfhound", several dog breeds have been specifically bred for the purpose, some of which, such as the Irish Wolfhound, have the word in their breed name.
Nuclear receptor
In the field of molecular biology, nuclear receptors are a class of proteins responsible for sensing steroids, thyroid hormones, vitamins, and certain other molecules. These intracellular receptors work with other proteins to regulate the expression of specific genes thereby controlling the development, homeostasis, and metabolism of the organism.
Video capture
Video capture is the process of converting an analog video signal—such as that produced by a video camera, DVD player, or television tuner—to digital video and sending it to local storage or to external circuitry. The resulting digital data are referred to as a digital video stream, or more often, simply video stream. Depending on the application, a video stream may be recorded as computer files, or sent to a video display, or both.
Erect image
In optics, an erect image is one that appears right-side up. An image is formed when rays from a point on the original object meet again after passing through an optical system. In an erect image, directions are the same as those in the object, in contrast to an inverted image. It is one of the properties of images formed in a plane mirror.
Kids Click
Helen Tam Yuk Ying (traditional Chinese: 譚玉瑛; simplified Chinese: 谭玉瑛; pinyin: Tán Yùyīng, born 27 November 1963) is a host of children's programmes in Hong Kong.She joined Television Broadcasts Limited (TVB) in 1980 and has hosted for children's shows since the 1980s, including 430 Space Shuttle (1982–1989), Flash Fax (1989–1999), Kids Click (2000–2004) and After School ICU (2005 - 2014). Therefore, she is often called "Sister Tam Yuk Ying" (譚玉瑛姐姐) as if she is an elder sister.
Web Services for Remote Portlets
Web Services for Remote Portlets (WSRP) is an OASIS-approved network protocol standard designed for communications with remote portlets.
Explosive belt
An explosive belt (also called suicide belt or a suicide vest) is an improvised explosive device, a belt or a vest packed with explosives and armed with a detonator, worn by suicide bombers. Explosive belts are usually packed with ball bearings, nails, screws, bolts, and other objects that serve as shrapnel to maximize the number of casualties in the explosion.
Facial colliculus
The facial colliculus is an elevated area located in the pontine tegmentum (dorsal pons), within the floor of the fourth ventricle (i.e. the rhomboid fossa). It is formed by fibres from the facial motor nucleus looping over the abducens nucleus. The facial colliculus is an essential landmark of the rhomboid fossa.
Effeminacy
Effeminacy is the embodiment of traits and/or expressions in those who are not of the female sex (e.g. boys and men) that are often associated with what is generally perceived to be feminine behaviours, mannerisms, styles, or gender roles, rather than with traditionally masculine behaviours, mannerisms, styles or roles. Effeminacy and other gender expressions are independent of a person's sexuality or sexual identity and are displayed by people of all sexualities and none. Effeminacy is seen in some societies as something embodied by some in the homosexual male community. The embodiment of effeminacy by people in some societies has resulted in prejudice, discrimination, antagonism and insults towards those who display it.
Computing with words and perceptions
In computing with words and perceptions (CWP), the objects of computation are words, perceptions, and propositions drawn from a natural language. The central theme of CWP is the concept of a generalised constraint. The meaning of a proposition is expressed as a generalised constraint. CWP is a necessary tool when the available information is perception-based or not precise enough to use numbers.
Sound reinforcement system
A sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers in enclosures all controlled by a mixing console that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience. In many situations, a sound reinforcement system is also used to enhance or alter the sound of the sources on the stage, typically by using electronic effects, such as reverb, as opposed to simply amplifying the sources unaltered.
Software Tools Users Group
The Software Tools Users Group (STUG) was a technical organization started in 1976, in parallel with Usenix. The STUG goal was to develop a powerful and portable Unix-like system that could be implemented on top of virtually any operating system, providing the capabilities and features of Unix in a non-proprietary system. With its focus on building clean, portable, reusable code shared amongst multiple applications and runnable on any operating system, the Software Tools movement reestablished the tradition of open source and the concepts of empowering users to define, develop, control, and freely distribute their computing environment.
Embedded C++
Embedded C++ (EC++) is a dialect of the C++ programming language for embedded systems. It was defined by an industry group led by major Japanese central processing unit (CPU) manufacturers, including NEC, Hitachi, Fujitsu, and Toshiba, to address the shortcomings of C++ for embedded applications. The goal of the effort is to preserve the most useful object-oriented features of the C++ language yet minimize code size while maximizing execution efficiency and making compiler construction simpler. The official website states the goal as "to provide embedded systems programmers with a subset of C++ that is easy for the average C programmer to understand and use".
Zerumbone synthase
Zerumbone synthase (EC 1.1.1.326, ZSD1) is an enzyme with systematic name 10-hydroxy-alpha-humulene:NAD+ oxidoreductase. This enzyme catalyses the following chemical reaction 10-hydroxy-alpha-humulene + NAD+ ⇌ zerumbone + NADH + H+The enzyme was cloned from shampoo ginger, Zingiber zerumbet.
Journal of NeuroInterventional Surgery
The Journal of NeuroInterventional Surgery is a peer-reviewed medical journal covering the field of neurointerventional surgery. It is published by the BMJ Group on behalf of the Society of NeuroInterventional Surgery. It is also the official journal of the Interventional Chapter of the Australian and New Zealand Society of Neuroradiology.It is abstracted and indexed by Current Contents, CINAHL and Index Medicus.
Faroese Braille
Faroese Braille is the braille alphabet of the Faroese language. It has the same basic letter assignments as the Scandinavian Braille and is quite similar to the Icelandic Braille.
Trivet
A trivet is an object placed between a serving dish or bowl, and a dining table, usually to protect the table from heat damage. Whilst tri- means three, and -vet comes from -ped, meaning 'foot' / 'feet', trivets often have four 'feet', and some trivets, including many wooden trivets, have no 'feet' at all.
Subjective visual vertical
Subjective Visual Vertical (SVV) is a diagnostic test of the inner ear to assess a patient's perception of verticality and detect if there are signs of an abnormal tilt that can cause dizziness or vertigo. It investigates the function of the utricle, one of two otolith organs located in the vertebrate inner ear, to evaluate the perception of verticality. As its name suggests, the test is subjective and cannot directly diagnose Acute Vestibular Syndrome (AVS), Ménière’s disease, vestibular migraine, vestibular neuritis or other central nervous system pathologies.
Canon EF 28-200mm lens
The EF28-200mm f/3.5-5.6 USM lens was a superzoom lens made by Canon Inc.
Conformal field theory
A conformal field theory (CFT) is a quantum field theory that is invariant under conformal transformations. In two dimensions, there is an infinite-dimensional algebra of local conformal transformations, and conformal field theories can sometimes be exactly solved or classified. Conformal field theory has important applications to condensed matter physics, statistical mechanics, quantum statistical mechanics, and string theory. Statistical and condensed matter systems are indeed often conformally invariant at their thermodynamic or quantum critical points.
2,4 Dienoyl-CoA reductase
2,4 Dienoyl-CoA reductase also known as DECR1 is an enzyme which in humans is encoded by the DECR1 gene which resides on chromosome 8. This enzyme catalyzes the following reactions DECR1 participates in the beta oxidation and metabolism of polyunsaturated fatty enoyl-CoA esters. Specifically, it catalyzes the reduction of 2,4 dienoyl-CoA thioesters of varying length by NADPH cofactor to 3-trans-enoyl-CoA of equivalent length. Unlike the breakdown of saturated fat, cis and trans polyunsaturated fatty acid degradation requires three additional enzymes to generate a product compatible with the standard beta oxidation pathway. DECR is the second such enzyme (the others being enoyl CoA isomerase and dienoyl CoA isomerase) and is the rate limiting step in this auxiliary flow. DECR is capable of reducing both 2-trans,4-cis-dienoyl-CoA and 2-trans,4-trans-dienoyl-CoA thioesters with equal efficiency. This is unusual, since most enzymes are highly stereoselective or stereospecific. There is no clear explanation for DECR's of lack of stereospecificity.
Nurturant parent model
The nurturant parent model also known as the "Nurturing Parent" is a metaphor used for a belief system, (built upon an underlying value system) that goes in contrast with the Stern Father (Strict Father) parenting belief system. Each system is reflects a contrasting value system in parenthood, i.e. conservative parenting and liberal parenting. The "Nurturant Parent" is one of the various parenting styles in practice in the world. A Nurturing Parent gives his/her children both "roots in the ground" and "wings to fly". The parent accomplishes this by conveying, role-modeling and enforcing boundaries which encourage the child to explore their personal freedom (trying their new wings) while practicing self-discipline as well. The Nurturant Parent model has a healthy respect for children's inherent intelligence. Thus children are allowed to explore their environment under a careful watch by their parents, who are responsible for protecting the child from serious mistakes, by offering guidance. A child will be picked up if the child cries because the parent wants the child to feel safe and supported. If a child grows up believing their needs are likely to be met, (s)he will grow out confident, ready to face challenges. Meanwhile the Nurturant Parent also encourages their children to have their roots deeply implanted in stable grounds. This is done by making the child practice appropriate amount of self-discipline and self-connection. They may be asked to do age-appropriate house chores, limit money they spend, take part in discussions of "feelings" and "thoughts" and practice setting healthy boundaries with strangers, friends and adults in general.
Dock4-Ex49
Dock4-Ex49 is a splice variant of the signalling protein Dock4 (Dedicator of cytokinesis 4). It has been found in the brain, inner ear and eye. It is able to bind and activate the small G protein Rac and may regulate the organisation of the actin cytoskeleton in the Stereocilia of the inner ear.
Lagrangian (field theory)
Lagrangian field theory is a formalism in classical field theory. It is the field-theoretic analogue of Lagrangian mechanics. Lagrangian mechanics is used to analyze the motion of a system of discrete particles each with a finite number of degrees of freedom. Lagrangian field theory applies to continua and fields, which have an infinite number of degrees of freedom.
Arabinogalactan
Arabinogalactan, also known as galactoarabinan, larch arabinogalactan, and larch gum, is a biopolymer consisting of arabinose and galactose monosaccharides. Two classes of arabinogalactans are found in nature: plant arabinogalactan and microbial arabinogalactan. In plants, it is a major component of many gums, including gum arabic and gum ghatti. It is often found attached to proteins, and the resulting arabinogalactan protein (AGP) functions as both an intercellular signaling molecule and a glue to seal plant wounds.The microbial arabinogalactan is a major structural component of the mycobacterial cell wall. Both the arabinose and galactose exist solely in the furanose configuration. The galactan portion of microbial arabinogalactan is linear, consisting of approximately 30 units with alternating β-(1-5) and β-(1-6) glycosidic linkages. The arabinan chain, which consists of about 30 residues, is attached at three branch points within the galactan chain, believed to be at residues 8, 10 and 12.
