John Casimir Zichy Woinarski is an Australian ornithologist, mammalogist, and herpetologist. He was awarded the 2001 Eureka Prize for Biodiversity Research. In the same year he was the recipient of the D. L. Serventy Medal, awarded by the Royal Australasian Ornithologists Union for outstanding published work on birds in the Australasian region.
Dr. Woinarski is currently Professor in the Research Institute for the Environment and Livelihoods, a part-time position at Charles Darwin University, in Darwin, Northern Territory. Much of his work has been focused on the conservation of threatened species and he has extensively published work on the responses of biodiversity to fire. He is a co-author of The Action Plan for Australian Mammals 2012.
In February 2019, speaking about the confirmed extinction of the Bramble Cay melomys, considered the only mammal endemic to the Great Barrier Reef and the first documented extinction of a mammal species due to climate change, he said that its loss was foreseeable and preventable. It had been known for years that its position was precarious, and he believed that its loss is at least partly due to under-funding for conservation programs and the fact that it was not an animal charismatic enough to garner much public attention.
After the 2019–20 Australian bushfire season Dr. Woinarski became a member of the Australian Commonwealth’s Wildlife and threatened species bushfire recovery Expert Panel.

https://en.wikipedia.org/wiki/Sean%20Hankin
|
Sean Hankin (born 28 February 1981) is an English former professional footballer who played as a defender in the Football League for Crystal Palace and Torquay United.
Life and career
Hankin was born in 1981 in Camberley, Surrey. He began his career as an apprentice at Crystal Palace, turning professional in June 1999. He made his league debut on 7 March 2000, coming on as a substitute for the injured Simon Rodger in the goalless draw with Bolton Wanderers at Selhurst Park, and agreed a new contract with Crystal Palace in June 2001.
Having made no more first-team appearances, Hankin joined Torquay United on loan in October 2001, as a replacement for fellow Palace player David Woozley who was returning to Selhurst Park at the end of his loan spell. He made his Torquay debut in the Football League Trophy against Bristol City and was sent off on his league debut in the 2–0 defeat away to Mansfield Town on 23 October. In December, he joined Torquay on a permanent deal for a £20,000 fee. Initially a regular in the Torquay side, Hankin lost his place in the team due to injury, was given only a short-term contract, and left in September 2003.
After brief spells with Hornchurch of the Isthmian League and Conference clubs Margate and Northwich Victoria, as well as training with Woking, Hankin settled at Crawley Town, helping them win the 2003–04 Southern League title and playing regularly in their first season in the Conference. He was released at the end of that season, and spent

|
The following tables list the computational complexity of various algorithms for common mathematical operations.
Here, complexity refers to the time complexity of performing computations on a multitape Turing machine. See big O notation for an explanation of the notation used.
Note: Due to the variety of multiplication algorithms, below stands in for the complexity of the chosen multiplication algorithm.
Arithmetic functions
This table lists the complexity of mathematical operations on integers.
On stronger computational models, specifically a pointer machine and consequently also a unit-cost random-access machine it is possible to multiply two -bit numbers in time O(n).
Algebraic functions
Here we consider operations over polynomials and denotes their degree; for the coefficients we use a unit-cost model, ignoring the number of bits in a number. In practice this means that we assume them to be machine integers.
Special functions
Many of the methods in this section are given in Borwein & Borwein.
Elementary functions
The elementary functions are constructed by composing arithmetic operations, the exponential function (), the natural logarithm (), trigonometric functions (), and their inverses. The complexity of an elementary function is equivalent to that of its inverse, since all elementary functions are analytic and hence invertible by means of Newton's method. In particular, if either or in the complex domain can be computed with some complexity, then that c

https://en.wikipedia.org/wiki/Hydroxytyrosol
|
Hydroxytyrosol is an organic compound with the formula . Classified as a phenylethanoid, i.e. a relative of phenethyl alcohol. Its derivatives are found in a variety of natural sources, notably olive oils and wines. Hydroxytyrosol is a colorless solid, although samples often turn beige during storage. It is a derivative, formally speaking, of catechol.
It or its derivatives occurs in olives and in wines
Occurrence
Olives
The olives, leaves, and olive pulp contain large amounts of hydroxytyrosol derivative Oleuropein, more so than olive oil). Unprocessed, green (unripe) olives, contain between 4.3 and 116 mg of hydroxytyrosol per 100g of olives, while unprocessed, black (ripe) olives contain up to 413.3 mg per 100g. The ripening of an olive substantially increases the amount of hydroxytyrosol. Processed olives, such as the common canned variety containing iron(II) gluconate, contained little hydroxytyrosol, as iron salts are catalysts for its oxidation.
Food safety
Hydroxytyrosol is considered safe as a novel food for human consumption, with a no-observed-adverse-effect level of 50 mg/kg body weight per day, as evaluated by the European Food Safety Authority (EFSA).
In the United States, hydroxytyrosol is considered to be a safe ingredient (GRAS) in processed foods at levels of 5 mg per serving.
Function and production
In nature, hydroxytyrosol is generated by the hydrolysis of oleuropein that occurs during olive ripening. Oleuropein accumulates in olive leaves and f

https://en.wikipedia.org/wiki/Phthalimide
|
Phthalimide is the organic compound with the formula C6H4(CO)2NH. It is the imide derivative of phthalic anhydride. It is a sublimable white solid that is slightly soluble in water but more so upon addition of base. It is used as a precursor to other organic compounds as a masked source of ammonia.
Preparation
Phthalimide can be prepared by heating phthalic anhydride with alcoholic ammonia giving 95–97% yield. Alternatively, it may be prepared by treating the anhydride with ammonium carbonate or urea. It can also be produced by ammoxidation of o-xylene.
Uses
Phthalimide is used as a precursor to anthranilic acid, a precursor to azo dyes and saccharin.
Alkyl phthalimides are useful precursors to amines in chemical synthesis, especially in peptide synthesis where they are used "to block both hydrogens and avoid racemization of the substrates". Alkyl halides can be converted to the N-alkylphthalimide:
C6H4(CO)2NH + RX + NaOH → C6H4(CO)2NR + NaX + H2O
The amine is commonly liberated using hydrazine:
C6H4(CO)2NR + N2H4 → C6H4(CO)2N2H2 + RNH2
Dimethylamine can also be used.
Some examples of phthalimide drugs include thalidomide, amphotalide, taltrimide, talmetoprim, and apremilast. With a trichloromethylthio substituent, a phthalimide-derived fungicide is Folpet.
Reactivity
It forms salts upon treatment with bases such as sodium hydroxide. The high acidity of the imido N-H is the result of the pair of flanking electrophilic carbonyl groups. Potassiu

https://en.wikipedia.org/wiki/Nv%20network
|
A Nv network is a term used in BEAM robotics referring to the small electrical Neural Networks that make up the bulk of BEAM-based robot control mechanisms.
Building blocks
The most basic component included in Nv Networks is the Nv neuron. The purpose of a Nv neuron is simply to take an input, do something with it, and give an output. The most common action of Nv neurons is to give a delay.
BEAM Nv Neurons
The standard for BEAM-based neurons is a capacitor that has one lead as an input, and the other going into the input line of an inverter. That inverter's output is the output of the neuron. The capacitor lead that is inputting into the inverter is pulled to ground with a resistor. The neuron functions because when an input is received (positive power on the input line), it charges the capacitor. Once the input is lost (negative power on the input line), the capacitor discharges into the inverter, causing the inverter to produce an output that is passed to the next neuron. The rate that the capacitor discharges is tied to the resistor that is pulling the input to the inverter to the negative. The larger the resistor, the longer it will take for the capacitor to fully discharge, and the longer it will take for that neuron to completely fire.
Types
There are many common network topologies used in BEAM robots, the most common of which are listed here.

Probably the most utilized Nv Net topology in BEAM, the Bicore consists of two neurons placed in a loop that alter

https://en.wikipedia.org/wiki/Biological%20value
|
Biological value (BV) is a measure of the proportion of absorbed protein from a food which becomes incorporated into the proteins of the organism's body. It captures how readily the digested protein can be used in protein synthesis in the cells of the organism. Proteins are the major source of nitrogen in food. BV assumes protein is the only source of nitrogen and measures the amount of nitrogen ingested in relation to the amount which is subsequently excreted. The remainder must have been incorporated into the proteins of the organisms body. A ratio of nitrogen incorporated into the body over nitrogen absorbed gives a measure of protein "usability" – the BV.
Unlike some measures of protein usability, biological value does not take into account how readily the protein can be digested and absorbed (largely by the small intestine). This is reflected in the experimental methods used to determine BV.
BV uses two similar scales:
The true percentage utilization (usually shown with a percent symbol).
The percentage utilization relative to a readily utilizable protein source, often egg (usually shown as unitless).
The two values will be similar but not identical.
The BV of a food varies greatly, and depends on a wide variety of factors. In particular the BV value of a food varies depending on its preparation and the recent diet of the organism. This makes reliable determination of BV difficult and of limited use — fasting prior to testing is universally required in order to ascert

https://en.wikipedia.org/wiki/Neuropoiesis
|
Neuropoiesis is the process by which neural stem cells differentiate to form mature neurons, astrocytes, and oligodendrocytes in the adult mammal. This process is also referred to as adult neurogenesis.
History
While rapid neurogenesis was known to occur in the early stages of life, the production and differentiation of neural stem cells was believed to cease upon maturity. This belief was overturned in the 1960s by the work of Joseph Altman. Using injections of thymidine-H3 to label the nuclei of dividing cells, Altman was able to use autoradiography to determine a neuronal birthdate for each cell in a rat's brain. This research revealed some degree of adult neurogenesis in the hippocampus and olfactory bulb of rats, and paved the way for the possibility of neuropoiesis in the adult mammalian brain.
Following Altman's work, thymidine-H3 injections were used to examine the brains of a variety of other species. In the late 1970s Steven Goldman used this technique to examine the vocal control centers of songbirds, and he found widespread evidence of adult neurogenesis in this area of a canary's brain. Subsequent studies by Goldman and others revealed the precise mechanisms for neuronal cell differentiation and migration in adult songbirds, and, along with studies done in fish and other species, laid the groundwork for the study of neuropoiesis in humans.

The most recognized initial sites of neuropoiesis ending with neurons in adults are

Daniel Cronström (29 September 1655 in Avesta Dalarna County – 30 August 1719 in Paris) was a Swedish architect working in the Late Baroque style, influenced by the French style of Louis XIV.
He entered the foreign service and served in France as a Commission Secretary in 1679. He was sent to Paris in the 1690s as a cultural ambassador whose duty it was to seek out, record in drawings and buy as much as he possibly could of first-rate material related to the decorative arts. The Tessin-Cronström correspondence is an archive of information on French style in architecture and the arts. An exhibition of such drawings from Swedish state collections devoted to Cronström and Nicodemus Tessin the Younger, "Versailles: The View From Sweden" was mounted at the Cooper-Hewitt Museum in New York City during 1988.

https://en.wikipedia.org/wiki/Pake%20doublet
|
A Pake Doublet (or "Pake Pattern") is a characteristic line shape seen in solid-state nuclear magnetic resonance and electron paramagnetic resonance spectroscopy. It was first described by George Pake.
It arises from dipolar coupling between isolated two spin-1/2 nuclei, or from transitions in quadrupolar nuclei such as deuterium. It is the general shape obtained from an orientationally dependent doublet. The "horns" of the Pake doublet correspond to the situation when the principal axis of the coupling interaction (the internuclear vector in the case dipolar coupling and the principal component of the electric field gradient tensor for quadrupolar nuclei) is perpendicular to the magnetic field. This situation is the most probable and the intensity is much higher. The "feet" of the lineshape correspond to the situation when the principal axis of the coupling interaction is parallel to the magnetic field which is much less statistically relevant.
Pake was the first to describe this lineshape and used it to extract the proton-proton distance from his experiments on a single crystal and powdered hydrates of gypsum (CaSO4.2H2O). This made it possible to experimentally determine the internuclear distance between the hydrogen atoms in water.
In solids with vacant positions, dipole coupling is averaged partially due to water diffusion which proceeds according to the symmetry of the solids and the probability distribution of molecules between the vacancies. In the case the av

https://en.wikipedia.org/wiki/Self-organising%20heuristic
|
In computing, a Self-organising heuristic is an algorithm that modifies a data structure such as a linked list in response to use of the data structure.
Examples might be:
Move-to-front (or 'Move to top')
Self-learning Frequency list (or 'Order by access frequency')
Re-insert at random position
Move to back
Example Applications
Move to front, or Order by access frequency, might be used to organize a cache of information, so that frequently used, or recently used information is at the top (and so can be found quickly, without having to traverse the whole list).
Order by frequency might be used to re-arrange a list of options in a GUI menu, so that the top ones are the ones most commonly selected by the user.
Re-insert at random or Move to back might be used to organise a list of mirror servers, so that once a server has been used for downloading, it goes to the back of the queue, to discourage the user from selecting it again.

https://en.wikipedia.org/wiki/Tree%20sort
|
A tree sort is a sort algorithm that builds a binary search tree from the elements to be sorted, and then traverses the tree (in-order) so that the elements come out in sorted order. Its typical use is sorting elements online: after each insertion, the set of elements seen so far is available in sorted order.
Tree sort can be used as a one-time sort, but it is equivalent to quicksort as both recursively partition the elements based on a pivot, and since quicksort is in-place and has lower overhead, tree sort has few advantages over quicksort. It has better worst case complexity when a self-balancing tree is used, but even more overhead.
Efficiency
Adding one item to a binary search tree is on average an process (in big O notation). Adding n items is an process, making tree sorting a 'fast sort' process. Adding an item to an unbalanced binary tree requires time in the worst-case: When the tree resembles a linked list (degenerate tree). This results in a worst case of time for this sorting algorithm.
This worst case occurs when the algorithm operates on an already sorted set, or one that is nearly sorted, reversed or nearly reversed. Expected time can however be achieved by shuffling the array, but this does not help for equal items.
The worst-case behaviour can be improved by using a self-balancing binary search tree. Using such a tree, the algorithm has an worst-case performance, thus being degree-optimal for a comparison sort. However, tree sort algorithms require

Cumberland High School is a public school located in Cumberland, Rhode Island. In its current location since 1962, the school serves approximately 1,500 students.
Statistics
History
The current building was built in 1961 and renovated in 1973. The town's mayor presented a capital improvement plan for the school in 2002, but funding was limited and residents questioned the project's first phase plans for a wellness center (athletic complex). A few months later, the New England Association of Schools and Colleges gave the school until October 2005 to improve the school's facilities and technology or have its accreditation status placed on probation.
A town referendum was held in September 2005 asking voters to approve the town borrowing $30 million to renovate Cumberland High School. The referendum's success is credited in part to a student group called Save Our Schools, which had been organized as part of the school's requirement of 15 hours of teacher-supervised service learning.
NASSP (the National Association of Secondary School Principals) designated Alan Tenreiro of Cumberland High School as 2016 National Principal of the Year.

https://en.wikipedia.org/wiki/Igneous%20intrusion
|
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California.
Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained (phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks.
Intrusions must displace existing country rock to make room for themselves. The question of how this takes place is called the room problem, and it remains a subject of active investigation for many kinds of intrusions.
The term pluton is poorly defined, but has been used to describe an intrusion emplaced at great depth; as a synonym for all igneous intrusions; as a dustbin category for intrusions whose size or character are not well determined; or as a name for a very large intrusion or for a crystallized magma chambe

META II is a domain-specific programming language for writing compilers. It was created in 1963–1964 by Dewey Val Schorre at UCLA. META II uses what Schorre called syntax equations. Its operation is simply explained as:
Each syntax equation is translated into a recursive subroutine which tests the input string for a particular phrase structure, and deletes it if found.
Meta II programs are compiled into an interpreted byte code language. VALGOL and SMALGOL compilers illustrating its capabilities were written in the META II language, VALGOL is a simple algebraic language designed for the purpose of illustrating META II. SMALGOL was a fairly large subset of ALGOL 60.
Notation
META II was first written in META I, a hand-compiled version of META II. The history is unclear as to whether META I was a full implementation of META II or a required subset of the META II language required to compile the full META II compiler.
In its documentation, META II is described as resembling BNF, which today is explained as a production grammar. META II is an analytical grammar. In the TREE-META document these languages were described as reductive grammars.
For example, in BNF, an arithmetic expression may be defined as:
<expr> := <term> | <expr> <addop> <term>
BNF rules are today production rules describing how constituent parts may be assembled to form only valid language constructs. A parser does the opposite taking language constructs apart. META II is a stack-based functional parser p

https://en.wikipedia.org/wiki/Happy%20mapping
|
In genetics, HAPPY Mapping, first proposed by Paul H. Dear and Peter R. Cook in 1989, is a method used to study the linkage between two or more DNA sequences. According to the Single Molecule Genomics Group, it is "Mapping based on the analysis of approximately HAPloid DNA samples using the PolYmerase chain reaction". In genomics, HAPPY mapping can be applied to assess the synteny and orientation of various DNA sequences across a particular genome - the generation of a "genomic" map.
As with linkage mapping, HAPPY mapping relies on the differential probability of two or more DNA sequences being separated. In genetic mapping, the probability of a recombination event between two genetic loci on the same chromosome is directly proportional to the distance between them. HAPPY mapping replaces recombination with fragmentation - instead of relying on recombination to separate genetic loci, the entire genome is fragmented, for example, by radiation or mechanical shearing. If the DNA is broken on a random basis, the longer the distance between two DNA sequences, the higher the chances of it to break between the two, and vice versa.
HAPPY mapping retains the benefits of genetic mapping while removing some of the problems associated with recombination. I.e., the need for polymorphism, and breeding. Also, recombination can be locale specific whereas breakage of genomic DNA by radiation or mechanical shearing seems to be more random. It has been used to genetically map several organis

https://en.wikipedia.org/wiki/Human%20accelerated%20regions
|
Human accelerated regions (HARs), first described in August 2006, are a set of 49 segments of the human genome that are conserved throughout vertebrate evolution but are strikingly different in humans. They are named according to their degree of difference between humans and chimpanzees (HAR1 showing the largest degree of human-chimpanzee differences). Found by scanning through genomic databases of multiple species, some of these highly mutated areas may contribute to human-specific traits. Others may represent loss of functional mutations, possibly due to the action of biased gene conversion rather than adaptive evolution.
Several of the HARs encompass genes known to produce proteins important in neurodevelopment. HAR1 is a 106-base pair stretch found on the long arm of chromosome 20 overlapping with part of the RNA genes HAR1F and HAR1R. HAR1F is active in the developing human brain. The HAR1 sequence is found (and conserved) in chickens and chimpanzees but is not present in fish or frogs that have been studied. There are 18 base pair mutations different between humans and chimpanzees, far more than expected by its history of conservation.
HAR2 includes HACNS1 a gene enhancer "that may have contributed to the evolution of the uniquely opposable human thumb, and possibly also modifications in the ankle or foot that allow humans to walk on two legs". Evidence to date shows that of the 110,000 gene enhancer sequences identified in the human genome, HACNS1 has undergone the m

|
In molecular biology, Human Accelerated Region 1 (Highly Accelerated Region 1, HAR1) is a segment of the human genome found on the long arm of chromosome 20. It is a human accelerated region. It is located within a pair of overlapping long non-coding RNA genes, HAR1A (HAR1F) and HAR1B (HAR1R).
HAR1A
HAR1A is expressed in Cajal–Retzius cells, contemporaneously with the protein reelin.
HAR1A was identified in August 2006 when human accelerated regions (HARs) were first investigated. These 49 regions represent parts of the human genome that differ significantly from highly conserved regions of our closest ancestors in terms of evolution. Many of the HARs are associated with genes known to play a role in neurodevelopment. One particularly altered region, HAR1, was found in a stretch of genome with no known protein-coding RNA sequences. Two RNA genes, HAR1F and HAR1R, were identified partly within the region. The RNA structure of HAR1A has been shown to be stable, with a secondary structure unlike those previously described.
HAR1A is active in the developing human brain between the 7th and 18th gestational weeks. It is found in the dorsal telencephalon in fetuses. In adult humans, it is found throughout the cerebellum and forebrain; it is also found in the testes. There is evidence that HAR1 is repressed by REST in individuals with Huntington's disease, perhaps contributing to the neurodegeneration associated with the disease.

https://en.wikipedia.org/wiki/Merocrine

Merocrine (or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology. A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and then onto a bodily surface or into the lumen.
Merocrine is the most common manner of secretion. The gland releases its product and no part of the gland is lost or damaged (compare holocrine and apocrine).
The term eccrine is specifically used to designate merocrine secretions from sweat glands (eccrine sweat glands), although the term merocrine is often used interchangeably.

Erna Spoorenberg, Huberdina Aletta Spoorenberg as real name, (11 April 192518 March 2004) was a Dutch soprano.
She was born in Yogyakarta, Java, Dutch East Indies (now Indonesia). As a child, she studied the violin and singing. At the age of 14, she studied under Isa Neuhaus, a singer with the Düsseldorf Opera (who was later transported and killed by the Nazis). Spoorenberg then studied singing under Aaltje Noordewier until she was 17, whilst continuing her violin lessons under Julius Röntgen. At the conservatory, she decided to pursue singing in preference to the violin. In 1947, she made her debut on Radio Hilversum, singing Mozart's motet Exsultate, jubilate.
In 1949, she auditioned for Karl Böhm and was given a guest contract at the Vienna State Opera, soon becoming a permanent member. Her performances there included:
Donizetti: Don Pasquale (Norina)
Millöcker: Der Bettelstudent (Laura)
Mozart: The Magic Flute (Pamina / Queen of the Night), Die Entführung aus dem Serail (Konstanze), Le nozze di Figaro, Don Giovanni (Donna Elvira), Così fan tutte (Fiordiligi)

https://en.wikipedia.org/wiki/Hyperchromicity
|
Hyperchromicity is the increase of absorbance (optical density) of a material. The most famous example is the hyperchromicity of DNA that occurs when the DNA duplex is denatured. The UV absorption is increased when the two single DNA strands are being separated, either by heat or by addition of denaturant or by increasing the pH level. The opposite, a decrease of absorbance is called hypochromicity.

Heat denaturation of DNA, also called melting, causes the double helix structure to unwind to form single stranded DNA. When DNA in solution is heated above its melting temperature (usually more than 80 °C), the double-stranded DNA unwinds to form single-stranded DNA. The bases become unstacked and can thus absorb more light. In their native state, the bases of DNA absorb light in the 260-nm wavelength region. When the bases become unstacked, the wavelength of maximum absorbance does not change, but the amount absorbed increases by 37%. A double stranded DNA strand dissociating to two single strands produces a sharp cooperative transition.
Hyperchromicity can be used to track the condition of DNA as temperature changes. The transition/melting temperature (Tm) is the temperature where the absorbance of UV light is 50% between the maximum and minimum, i.e. where 50% of the DNA is denatured. A ten fold increase of monovalent cation concentration increases the temperature by 16.6 °C.
The hyperchromic effect is the striking increase in absorbanc

|
The surname Story (and its variant spelling Storey) originates from the Old Norse personal epithet “Stóri”, a derivative of “Storr” which means “large” or “big”. Even though it has been established that the root of the name is “Storr”, R.E.K. Rigbeye, in his book The Storey’s of Old claims that the suffix “ey[e]”, in the variant of Storey, is equivalent to the Icelandic “ig” and signifies “water”. According to him, “Storr” also denotes large in the sense of vast and rough. Rigbeye's assumption therefore, is that “Storey” means "dweller by large and rough water". This may be explained by the Norse affinity to sea exploration, or the fact that the first Storys settled near the Lake District, and so the name might refer to the habitation which they chose. The earliest Norse settlement of which the first Storys would have been a part, took place in the 9th century north of Carlisle near the Solway Firth. This area then known as Strathclyde, was situated in the northwestern part of England, along the Scottish border. The earliest Storys would have settled on the English side of the border, most likely in the plains along the river Eden. The English or Anglo-Saxon population, among whom the Norse settled, spoke a similar language but pronounced many words in a different way. So, “Storr” among the Norse would have been enunciated as “Styr” in English.
History
One of the earliest mentions of the name is “Styr (Saxon for Stor) who gave the manor of Durham with other places to the Abb

https://en.wikipedia.org/wiki/Thromboxane%20receptor
|
The thromboxane receptor (TP) also known as the prostanoid TP receptor is a protein that in humans is encoded by the TBXA2R gene, The thromboxane receptor is one among the five classes of prostanoid receptors and was the first eicosanoid receptor cloned. The TP receptor derives its name from its preferred endogenous ligand thromboxane A2.
Gene
The gene responsible for directing the synthesis of the thromboxane receptor, TBXA2R, is located on human chromosome 19 at position p13.3, spans 15 kilobases, and contains 5 exons. TBXA2R codes for a member of the G protein-coupled super family of seven-transmembrane receptors.
Heterogeneity
Molecular biology findings have provided definitive evidence for two human TP receptor subtypes. The originally cloned TP subtype from human placenta is known as the α isoform and the splice variant cloned from endothelium (with 407 amino acids) is termed the β isoform. The first 328 amino acids are the same for both isoforms, but the β isoform exhibits an extended C-terminal cytoplasmic domain. Both isoforms stimulate cells in part by activating the Gq family of G proteins. In at least certain cell types, however, TPα also stimulates cells by activating the Gs family of G proteins while TPβ also stimulates cells by activating the Gi class of G proteins. This leads to the stimulation or inhibition, respectively, of adenylate cyclase activity and thereby very different cellular responses. Differences in their C-terminal tail sequence also allow

Rorà is a comune (municipality) in the Metropolitan City of Turin in the Italian region Piedmont, located about 50 km southwest of Turin
Situated 5 km from Luserna San Giovanni, the small center of Rorà lies at the foot of Mount Frioland in the upper valley of the river Luserna.
In its territory are the quarries that since antiquity were used to extract the renowned Luserna stone, and the houses of the village shows beautiful walls made with this stone.
It was the scene of several campaigns against the Waldensians and is historically linked to Joshua Janavel. Nearby Torre Pellice is the center of the Waldensian church.
Rorà borders the following municipalities: Villar Pellice, Torre Pellice, Luserna San Giovanni, and Bagnolo Piemonte.
History
Rorà is the transcription of the ancient name of the village, which means oakwood (from rou, oak), alluding to the woods that once covered the valley. The existence of a municipal organization with delimitation of borders (still substantially unchanged) is attested by a document dated 1251. Its history is similar to all the mountain villages of Piedmont: initially was a fief of a noble family (Luserna), later a free community.
The history of Rorà is also characterized (as well as several surrounding municipalities, part of the so-called Waldensian valleys) by the presence of the Waldensians, a religious movement born in the twelfth century in Lyon from the story of Valdo (hence the name), a merchant who abandoned all their own bel

Arvingarna is a Swedish dansband formed in Gothenburg in 1989. The group consists of Casper Janebrink (vocals and bass guitar), Lars Larsson (guitars, vocals and keyboards), Kim Carlsson (vocals and guitars) and Tommy Carlsson (drums and vocals). At Melodifestivalen 1993, they performed the song '"Eloise", which won, allowing Arvingarna to represent Sweden in the Eurovision Song Contest in Millstreet Co.Cork in May that year, where the song finished 7th.
History
Arvingarna was founded in 1989, following the members earlier having played heavy metal, without any major successes. The band's name ("The heirs") refers to the group member's parents, who also were active in dansbands. Arvingarna plays a form of dansband music that is it inspired by pop music and rock music, and has also being described as a boyband.
The band has competed in the Swedish Melodifestivalen in 1993, 1995, 1999, 2002, 2019 and 2021.
In 2019 they participated in Melodifestivalen 2019 with the song "I Do", where they placed 7th in the final scoring 64 points. The band returned two years later and participated in Melodifestivalen 2021 with the song "Tänker inte alls gå hem" taking part in the first heat on 6 February 2021 where they qualified directly for the finale. The finale was held on 13 March 2021 at the Annexet in Stockholm. Arvingarna finished 9th in the final with a total of 44 points.

https://en.wikipedia.org/wiki/Thomas%20Wilbrandt
|
Thomas Wilbrandt (born 1952 in Bielefeld) is a German composer and conductor.
He studied with Franco Ferrara, Hans Swarowsky and Bruno Maderna in Rome, Vienna and Salzburg and was Assistant to Herbert von Karajan and the Berlin Philharmonic for three years in Berlin and Salzburg.
In 1980 he founded the Berlin Chamber Academy (Berliner Kammer-Akademie), a forty-piece orchestra originally formed from players of the Berlin Philharmonic, with whom he recorded a Mozart Series for RCA/Victor.
Next to international conducting activities and cooperations with orchestras such as the Berlin Philharmonic and the Philharmonia Orchestra in London, Wilbrandt became more involved in his own projects and recordings, concentrating on his work as a composer, especially in the field of Avant-garde and electronic music. This led to developed experimentation regarding multimedia content and expression and to the constant exploration of new forms of music presentation.
One of his first major projects was the creation of a fusion between acoustic orchestral playing and digital and electronic instruments and sounds, entitled THE ELECTRIC V., an approach to Vivaldi's concert cycle The Four Seasons. The first edition of THE ELECTRIC V. was released in 1984 in twenty countries. Wilbrandt wrote, directed, and produced THE ELECTRIC V. film between 1987 and 1990.
Wilbrandt contributed music to the soundtrack of Oliver Stone's film Natural Born Killers.

|
Dryad is a rural unincorporated community in Lewis County, Washington. The town of Doty is 1.3-miles to the west, with Adna and Ceres to the east, on Washington State Route 6. The Chehalis River bisects the area.
Etymology
The community was formerly known as Salal. The name Dryad was supplied by Northern Pacific Railway officials around 1890 at the suggestion of Willam C. Albee, who was superintendent of the Pacific Division of the NP. In mythology, a dryad was a wood nymph. Albee figured that a dryad might find itself right at home living in the local fir and cedar trees.
History
Dryad is one of many former lumber towns that sprang up on the Willapa Harbor Line (Chehalis, Washington to South Bend, Washington) of the Northern Pacific Railway. The town was originally located two miles south of the present location. The community moved when the Leudinghaus brothers of Chehalis built a sawmill at the present site in 1902.
The Dryad Community Baptist Church was built in 1903 and has remained open since its construction. Renovations in 2006 were done to the bell tower and roof, with stained glass windows installed in 2018.
Climate
This region experiences warm (but not hot) and dry summers, with no average monthly temperatures above 71.6 °F. According to the Köppen Climate Classification system, Dryad has a warm-summer Mediterranean climate, abbreviated "Csb" on climate maps.
Parks and Recreation
The annual Pe Ell River Run passes through Dryad. Held since 1978, the event co

https://en.wikipedia.org/wiki/Kynurenic%20acid
|
Kynurenic acid (KYNA or KYN) is a product of the normal metabolism of amino acid -tryptophan. It has been shown that kynurenic acid possesses neuroactive activity. It acts as an antiexcitotoxic and anticonvulsant, most likely through acting as an antagonist at excitatory amino acid receptors. Because of this activity, it may influence important neurophysiological and neuropathological processes. As a result, kynurenic acid has been considered for use in therapy in certain neurobiological disorders. Conversely, increased levels of kynurenic acid have also been linked to certain pathological conditions.
Kynurenic acid was discovered in 1853 by the German chemist Justus von Liebig in dog urine, which it was apparently named after.
It is formed from -kynurenine in a reaction catalyzed by the enzyme kynurenine—oxoglutarate transaminase.
Mechanism of action
KYNA has been proposed to act on five targets:
As an antagonist at ionotropic AMPA, NMDA and Kainate glutamate receptors in the concentration range of 0.1-2.5 mM.
As a noncompetitive antagonist at the glycine site of the NMDA receptor.
As an antagonist of the α7 nicotinic acetylcholine receptor. However, recently (2011) direct recording of α7 nicotinic acetylcholine receptor currents in adult (noncultured) hippocampal interneurons by the Cooper laboratory validated a 2009 study that failed to find any blocking effect of kynurenic acid across a wide range of concentrations, thus suggesting that in noncultured, intact pre

Turtle Mound is a prehistoric archaeological site located south of New Smyrna Beach, Florida, on State Road A1A. On September 29, 1970, it was added to the U.S. National Register of Historic Places. It is the largest shell midden on the mainland United States, with an approximate height of . The mound extends for over along the Indian River shoreline and contains over of shells. Turtle Mound was estimated to be high before it was reduced by shellrock mining in the 19th and 20th centuries. Because it is visible seven miles out at sea, early Spanish explorers and subsequent mariners used the large mound as a landmark for coastal navigation. Today, the site is owned and managed by the National Park Service as part of Canaveral National Seashore.
The turtle-shaped mound contains oysters and refuse from the prehistoric Timucuan people, who caught a variety of small mammals and reptiles here. Archaeologists believe that these people may have used this site as a high-ground refuge during hurricanes. It has been estimated to have been constructed between 800 and 1400 CE; recent radio-carbon dating has dated it toaround 1000 BCE.
The Timucuan experienced greater competitive forces for finite resources such as arable land resulting in increased open conflict. This is apparent in some of the material found in the Turtle Mound location where it occupied an important location along the coast. Archaeologists have recently found 1,200-year-old pottery on the site.

The conditional distribution of given is thus a normal distribution with mean and variance . A normal variance-mean mixture can be thought of as the distribution of a certain quantity in an inhomogeneous population consisting of many different normal distributed subpopulations. It is the distribution of the position of a Wiener process (Brownian motion) with drift and infinitesimal variance observed at a random time point independent of the Wiener process and with probability density function . An important example of normal variance-mean mixtures is the generalised hyperbolic distribution in which the mixing distribution is the generalized inverse Gaussian distribution.

|
Microsoft Point-to-Point Compression (MPPC; described in RFC 2118) is a streaming data compression algorithm based on an implementation of Lempel–Ziv using a sliding window buffer. According to Hifn's IP statement, MPPC was patent-encumbered (last US patent granted on 1996-07-02).
Whereas V.44 or V.42bis operate at layer 1 on the OSI model, MPPC operates on layer 2, giving it a significant advantage in terms of computing resources available to it. The dialup modem's in-built compression (V.44 or V.42bis) can only occur after the data has been serially transmitted to the modem, typically at a maximum rate of 115,200 bit/s. MPPC, as it is controlled by the operating system, can receive as much data as it wishes to compress, before forwarding it on to the modem.
The modem's hardware must not delay data too much, while waiting for more to compress in one packet, otherwise an unacceptable latency level will result. It also cannot afford to, as this would require both sizable computing resources (on the scale of a modem) as well as significant buffer RAM. Software compression such as MPPC is free to use the host computer's resources, exceeding the modem's by several orders of magnitude. This allows it to keep a much larger buffer to work on at any one time, and it processes through a given amount of data much faster.
The end result is that where V.44 may achieve a maximum of 4:1 compression (230 kbit/s) but is usually limited to 115.2 kbit/s, MPPC is capable of a maximum of 8:1

https://en.wikipedia.org/wiki/Bovine%20papillomavirus
|
Bovine papillomaviruses (BPV) are a paraphyletic group of DNA viruses of the subfamily Firstpapillomavirinae of Papillomaviridae that are common in cattle. All BPVs have a circular double-stranded DNA genome. Infection causes warts (papillomas and fibropapillomas) of the skin and alimentary tract, and more rarely cancers of the alimentary tract and urinary bladder. They are also thought to cause the skin tumour equine sarcoid in horses and donkeys.
BPVs have been used as a model for studying papillomavirus molecular biology and for dissecting the mechanisms by which this group of viruses cause cancer.
Structure and genetic organisation
Like other papillomaviruses, BPVs are small non-enveloped viruses with an icosahedral capsid around 50–60 nm in diameter. The capsid is formed of the L1 and L2 structural proteins, with the L1 C-terminus exposed.
All BPVs have a circular double-stranded DNA genome of 7.3–8.0 kb. The genetic organisation of those BPVs which have been sequenced is broadly similar to other papillomaviruses. The open reading frames (ORFs) are all located on one strand, and are divided into early and late regions. The early region encodes nonstructural proteins E1 to E7. There are three viral oncoproteins, E5, E6 and E7; BPVs of the Xipapillomavirus group lack E6. The late region encodes structural proteins L1 and L2. There is also a non-coding long control region (LCR).
Types
Six types of BPV have been characterised, BPV-1 to BPV-6, which are divided into three

Apolipoprotein B deficiency is an autosomal dominant disorder resulting from a missense mutation which reduces the affinity of apoB-100 for the low-density lipoprotein receptor (LDL Receptor). This causes impairments in LDL catabolism, resulting in increased levels of low-density lipoprotein in the blood. The clinical manifestations are similar to diseases produced by mutations of the LDL receptor, such as familial hypercholesterolemia. Treatment may include, niacin or statin or ezetimibe.
It is also known as "normotriglyceridemic hypobetalipoproteinemia".

https://en.wikipedia.org/wiki/Carbamoyl%20phosphate%20synthetase%20I%20deficiency
|
Carbamoyl phosphate synthetase I deficiency (CPS I deficiency) is an autosomal recessive metabolic disorder that causes ammonia to accumulate in the blood due to a lack of the enzyme carbamoyl phosphate synthetase I. Ammonia, which is formed when proteins are broken down in the body, is toxic if the levels become too high. The nervous system is especially sensitive to the effects of excess ammonia.
Signs and symptoms
Carbamoyl phosphate synthetase I deficiency often becomes evident in the first few days of life. An infant with this condition may be lacking in energy (lethargic) or unwilling to eat, and have a poorly controlled breathing rate or body temperature. Some babies with this disorder may experience seizures or unusual body movements, or go into a coma. Complications of carbamoyl phosphate synthetase I deficiency may include developmental delay and mental retardation.
In some affected individuals, signs and symptoms of carbamoyl phosphate synthetase I deficiency may be less severe, and may not appear until later in life.
Genetics
CPS I deficiency is inherited in an autosomal recessive manner. This means the defective gene responsible for the disorder is located on an autosome, and two copies of the defective gene (one inherited from each parent) are required in order to be born with the disorder. The parents of an individual with an autosomal recessive disorder both carry one copy of the defective gene, but usually do not experience any signs or symptoms of the

|
Ethylmalonic encephalopathy (EE) is a rare autosomal recessive inborn error of metabolism. Patients affected with EE are typically identified shortly after birth, with symptoms including diarrhea, petechiae and seizures. The genetic defect in EE is thought to involve an impairment in the degradation of sulfide intermediates in the body. Hydrogen sulfide then builds up to toxic levels. EE was initially described in 1994. Most cases of EE have been described in individuals of Mediterranean or Arabic origin.
Signs and symptoms
Neurologic signs and symptoms include progressively delayed development, weak muscle tone (hypotonia), seizures, and abnormal movements. The body's network of blood vessels is also affected. Children with this disorder may experience rashes of tiny red spots (petechiae) caused by bleeding under the skin and blue discoloration in the hands and feet due to reduced oxygen in the blood (acrocyanosis). Chronic diarrhea is another common feature of ethylmalonic encephalopathy. EE is often identified by urine organic acid analysis, the excretion of ethylmalonic acid, methylsuccinic acid, isobutyrylglycine and isovalerylglucine. Patients will also often have elevated thiosulphate concentration in their urine.
The signs and symptoms of ethylmalonic encephalopathy are apparent at birth or begin in the first few months of life. Problems with the nervous system typically worsen over time, and most affected individuals survive only into early childhood. A few

Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue and can also serve as a fuel source. As a fuel, proteins provide as much energy density as carbohydrates: 4 kcal (17 kJ) per gram; in contrast, lipids provide 9 kcal (37 kJ) per gram. The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition.
Proteins are polymer chains made of amino acids linked together by peptide bonds. During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions. This is crucial for the absorption of the essential amino acids that cannot be biosynthesized by the body.
There are nine essential amino acids which humans must obtain from their diet in order to prevent protein-energy malnutrition and resulting death. They are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine. There has been debate as to whether there are 8 or 9 essential amino acids. The consensus seems to lean towards 9 since histidine is not synthesized in adults. There are five amino acids which humans are able to synthesize in the body. These five are alanine, aspartic acid, asparagine, glutamic acid and serine. There are six conditionally essential amino acids whose synthesis can be limited under special pathophysiological conditions, such as prematurity in the infant or individuals in severe

|
Roy John Britten (1 October 1919 – 21 January 2012) was an American molecular biologist known for his discovery of repeated DNA sequences in the genomes of eukaryotic organisms, and later on the evolution of the genome.
Early life and education
Roy Britten was born in Washington, D.C. He attended Upper Canada College in Toronto, Ontario, and then went to the University of Virginia to study physics. He enrolled at Johns Hopkins University as a graduate student in physics in 1940. At the beginning of World War II, he was recruited to work on the Manhattan Project. In 1951, he received his Ph.D. from Princeton University. His Ph.D. thesis was entitled The Scattering of 32 MeV Protons from Several Elements.
Scientific career
From 1951 to 1971, he was a staff member at the Carnegie Institution of Washington, Department of Terrestrial Magnetism. While there he attended the phage course at the Cold Spring Harbor Laboratory and started working on the processes by which genetic information becomes expressed as proteins. This work was conducted with colleagues Bill H. Hoyer, Brian J. McCarthy, Ellis T. Bolton, Richard B. Roberts, David Kohne, and others. This work led him to want to understand the structure of the chromosome, which was little understood at the time. He developed a new method to explore the sequence structure of DNA using the idea of DNA hybridization. Through this work, he showed that eukaryotic genomes have many repetitive, non-coding DNA sequences, known as re

https://en.wikipedia.org/wiki/White%20British
|
White British is an ethnicity classification used for the native white population identifying as English, Scottish, Welsh, Cornish, Northern Irish, or British in the United Kingdom Census. In the 2011 census, the White British population was 49,997,686, 81.5% of Great Britain's total population. For the United Kingdom entirely, due to different reporting measures within Northern Ireland which includes all those who identified as British with those who identified as Irish, an amalgamated total of 52,320,080 including those who identified as White Irish in Great Britain is given making up 82.8% of the population.
Census classifications
For the 2011 census, in England and Wales, the White self-classification option included a subcategory of "English/Welsh/Scottish/Northern Irish/British". In Scotland, the White category included "Scottish" and "Other British" options. In Northern Ireland, the White British classification did not appear, the only choice being 'White'.
The 2011 census for England, Wales and Scotland also included additional White ethnic classifications of White Irish, White Gypsy/Irish Traveller and White Other. There were calls for the 2011 national census in England and Wales to include an extra subcategory so people could identify their ethnic group as Cornish.

https://en.wikipedia.org/wiki/Bush%20bread
|
Bush bread, or seedcakes, refers to the bread made by Aboriginal Australians by crushing seeds into a dough that is then baked. The bread is high in protein and carbohydrate, and forms part of a balanced traditional diet. It is also sometimes referred to as damper, although damper
is more commonly used to describe the bread made by non-Indigenous people.
With the arrival of Europeans and pre-milled white flour, this bread-making process has almost disappeared (although women were still recorded to be making seedcakes in Central Australia in the 1970s). The tradition of cooking bread in hot coals continues today.
Bread-making was a woman's task. It was generally carried out by several women at once, due to its labour-intensive nature. It involved collecting seasonal grains, legumes, roots or nuts, and preparing these into flour and then dough, or directly into a dough. One of the traditional ingredients was the seeds of kangaroo grass.
Bread-making from seeds
Collecting the seed
Seeds varied depending on the time of year and the area in Australia that the people lived. In Central Australia, native millet (Panicum decompositum; Panicum australianse) and spinifex (Triodia) were commonly used. Wattleseed could also be used in the flour mix.
Women harvested the fully ripe, dry seeds of the plant by beating the grass (or pod-laden trees in the case of wattleseed) with sticks to dislodge the seeds. Some species were eaten at the green stage and, when ground, would produce a ju

https://en.wikipedia.org/wiki/Normal-inverse%20Gaussian%20distribution
|
The normal-inverse Gaussian distribution (NIG, also known as the normal-Wald distribution) is a continuous probability distribution that is defined as the normal variance-mean mixture where the mixing density is the inverse Gaussian distribution. The NIG distribution was noted by Blaesild in 1977 as a subclass of the generalised hyperbolic distribution discovered by Ole Barndorff-Nielsen. In the next year Barndorff-Nielsen published the NIG in another paper. It was introduced in the mathematical finance literature in 1997.
The parameters of the normal-inverse Gaussian distribution are often used to construct a heaviness and skewness plot called the NIG-triangle.

The fact that there is a simple expression for the moment generating function implies that simple expressions for all moments are available.

https://en.wikipedia.org/wiki/DCL%20Technology%20Demonstrator%20programme
|
The US DCL (Detection Classification and Localisation) demonstrator program is aimed at proving that an active torpedo detection system is able to resolve a salvo of torpedoes with sufficient time and accuracy that an anti-torpedo torpedo may be fired back to hit and destroy the threat.
Overview
The DCL systems consist of an active source emitter which sends high-frequency pings into the water. Reflections from in-water objects are received by a towed array tuned to those frequencies. By processing the reflections it is possible to determine whether objects are torpedoes, or non-threat objects.
The system is also combined with a passive acoustic towed array specifically designed for torpedo detection. The passive acoustic array is able to analyse the structured sound emanating from a torpedo and thereby classify the weapon type and mode of operation.
Two teams are currently building alternative DCL demonstration systems, the first to test was Ultra Electronics who in 2006 successfully resolved a salvo of torpedoes. The second company APC has yet to undergo tests.
The aim of the programme is to resolve threats sufficiently well that an anti-torpedo torpedo may be fired at the threat to neutralise it (a hard-kill solution). This differs from the UK S2170 Surface Ship Torpedo Defence solution which utilises soft-kill.

https://en.wikipedia.org/wiki/Variance-gamma%20distribution
|
The variance-gamma distribution, generalized Laplace distribution or Bessel function distribution is a continuous probability distribution that is defined as the normal variance-mean mixture where the mixing density is the gamma distribution. The tails of the distribution decrease more slowly than the normal distribution. It is therefore suitable to model phenomena where numerically large values are more probable than is the case for the normal distribution. Examples are returns from financial assets and turbulent wind speeds. The distribution was introduced in the financial literature by Madan and Seneta. The variance-gamma distributions form a subclass of the generalised hyperbolic distributions.
The fact that there is a simple expression for the moment generating function implies that simple expressions for all moments are available. The class of variance-gamma distributions is closed under convolution in the following sense. If and are independent random variables that are variance-gamma distributed with the same values of the parameters and , but possibly different values of the other parameters, , and , respectively, then is variance-gamma distributed with parameters , , and .
The variance-gamma distribution can also be expressed in terms of three inputs parameters (C,G,M) denoted after the initials of its founders. If the "C", here, parameter is integer then the distribution has a closed form 2-EPT distribution. See 2-EPT Probability Density Function. Under

Gaius Claudius Pulcher was a Roman Republic consul in 92 BC, together with Marcus Perperna. His great-grandfather was Gaius Claudius Pulcher in 177 BC.
In 100 BC, he was one of those took up arms against Saturninus. In 99 BC, he was curule aedile, and in the games celebrated by him elephants were for the first time exhibited in the circus, and painting employed in the scenic decorations. In 95 BC, he was praetor in Sicily, and, by direction of the senate, gave laws to the Halesini respecting the appointment of their senate. The Mamertines made him their patronus. He was consul in 92 BC. Cicero speaks of him as a man possessed of great power and some ability as an orator.

https://en.wikipedia.org/wiki/Pentraxins
|
Pentraxins (PTX), also known as pentaxins, are an evolutionary conserved family of proteins characterised by containing a pentraxin protein domain. Proteins of the pentraxin family are involved in acute immunological responses. They are a class of pattern recognition receptors (PRRs). They are a superfamily of multifunctional conserved proteins, some of which are components of the humoral arm of innate immunity and behave as functional ancestors of antibodies (Abs). They are known as classical acute phase proteins (APP), known for over a century.
Structure
Pentraxins are characterised by calcium dependent ligand binding and a distinctive flattened β-jellyroll structure similar to that of the legume lectins. The name "pentraxin" is derived from the Greek word for five (, pente) and axle (axis) relating to the radial symmetry of five monomers forming a ring approximately 95Å across and 35Å deep observed in the first members of this family to be identified. The "short" pentraxins include Serum Amyloid P component (SAP) and C reactive protein (CRP). The "long" pentraxins include PTX3 (a cytokine modulated molecule) and several neuronal pentraxins.
Family members
Three of the principal members of the pentraxin family are serum proteins: namely, CRP, SAP, and hamster female protein (FP). PTX3 (or TSG-14) protein is a cytokine-induced protein that is homologous to CRPs and SAPs.

https://en.wikipedia.org/wiki/LORAX
|
The Life On ice: Robotic Antarctic eXplorer or LORAX is an experimental robotics project being developed by the Robotics Institute of Carnegie Mellon University, supported by NASA. The intent of the project is to create an autonomous rover to survey the distribution of microbes on Antarctica's ice sheets. It is unknown whether it intentionally shares a name with The Lorax, the environmentalist Dr. Seuss character.
The goal is to create a robotic platform with full navigational autonomy and clean, sustainable power systems. This complete isolation will allow the robot to operate unattended and avoid any possible contamination of its results. The project aims for the robot to be able to operate for one month without human intervention. The rover's power systems incorporate a combination of solar power and wind power. Several solar panels are mounted on the shell of the rover. It also has a deployable wind turbine for generating further power.
A working model of the LORAX rover called Nomad was tested in 2005 on the frozen Mascoma Lake in New Hampshire. The rover completed a ten kilometer test run, traversed ice obstacles and conducted a successful test of its wind turbine. The rover, independent of any human guidance, traveled over fourteen kilometers in all on the frozen lake and returned to its starting point. The test also yielded further calibrations to many of the rover's systems.

https://en.wikipedia.org/wiki/Restriction%20map
|
A restriction map is a map of known restriction sites within a sequence of DNA. Restriction mapping requires the use of restriction enzymes. In molecular biology, restriction maps are used as a reference to engineer plasmids or other relatively short pieces of DNA, and sometimes for longer genomic DNA. There are other ways of mapping features on DNA for longer length DNA molecules, such as mapping by transduction.
One approach in constructing a restriction map of a DNA molecule is to sequence the whole molecule and to run the sequence through a computer program that will find the recognition sites that are present for every restriction enzyme known.
Before sequencing was automated, it would have been prohibitively expensive to sequence an entire DNA strand. To find the relative positions of restriction sites on a plasmid, a technique involving single and double restriction digests is used. Based on the sizes of the resultant DNA fragments the positions of the sites can be inferred. Restriction mapping is a very useful technique when used for determining the orientation of an insert in a cloning vector, by mapping the position of an off-center restriction site in the insert.
Method
The experimental procedure first requires an aliquot of purified plasmid DNA (see appendix) for each digest to be run. Digestion is then performed with each enzyme(s) chosen. The resulting samples are subsequently run on an electrophoresis gel, typically on agarose gel.

https://en.wikipedia.org/wiki/Diagnostic%20peritoneal%20lavage
|
Diagnostic peritoneal lavage (DPL) or diagnostic peritoneal aspiration (DPA) is a surgical diagnostic procedure to determine if there is free floating fluid (most often blood) in the abdominal cavity.
Indications
This procedure is performed when intra-abdominal bleeding (hemoperitoneum), usually secondary to trauma, is suspected. In a hemodynamically unstable patient with high-risk mechanism of injury, peritoneal lavage is a means of rapidly diagnosing intra-abdominal injury requiring laparotomy, but has largely been replaced in trauma care by the use of a focused assessment with sonography for trauma (FAST scan) due to its repeatability, non-invasiveness and non-interference with subsequent computed tomography (CT scan). Abdominal CT and contrast duodenography may complement lavage in stable patients, but in an unstable or uncooperative persons, these studies are too time-consuming or require ill-advised sedation. Magnetic resonance imaging is extremely accurate for the anatomic definition of structural injury, but logistics limit its practical application in acute abdominal trauma.
The procedure was first described in 1965 by Hauser Root.
Procedure
After the application of local anesthesia, a vertical skin incision is made one third of the distance from the umbilicus to the pubic symphysis. The linea alba is divided and the peritoneum entered after it has been picked up to prevent bowel perforation. A catheter is inserted towards the pelvis and aspiration of material at

https://en.wikipedia.org/wiki/Glia%20limitans
|
The glia limitans, or the glial limiting membrane, is a thin barrier of astrocyte foot processes associated with the parenchymal basal lamina surrounding the brain and spinal cord. It is the outermost layer of neural tissue, and among its responsibilities is the prevention of the over-migration of neurons and neuroglia, the supporting cells of the nervous system, into the meninges. The glia limitans also plays an important role in regulating the movement of small molecules and cells into the brain tissue by working in concert with other components of the central nervous system (CNS) such as the blood–brain barrier (BBB).
Location and structure
The perivascular feet of astrocytes form a close association with the basal lamina of the brain parenchyma to create the glia limitans. This membrane lies deep to the pia mater and the subpial space and surrounds the perivascular spaces (Virchow-Robin spaces). Any substance entering the central nervous system from the blood or cerebrospinal fluid (CSF) must cross the glia limitans.
The two different classifications of glial limiting membrane, the glia limitans perivascularis and the glia limitans superficialis, have nearly identical structures, however, they can be distinguished from each other by their location within the brain. The glia limitans perivascularis abuts the perivascular space surrounding the parenchymal blood vessels and functions as a supportive constituent of the blood–brain barrier. In contrast, the non-parenchymal

https://en.wikipedia.org/wiki/Syrinx%20%28medicine%29
|
A syrinx is a rare, fluid-filled neuroglial cavity within the spinal cord (syringomyelia), in the brain stem (syringobulbia), or in the nerves of the elbow, usually in a young age.
Presentation
Symptoms usually begin insidiously between adolescence and age 45. Syringomyelia develops in the center of the spinal cord, causing a central cord syndrome. Pain and temperature sensory deficits occur early but may not be recognized for years. The first abnormality recognized may be a painless burn or cut. Syringomyelia typically causes weakness, atrophy, and often fasciculations and hyperreflexia of the hands and arms; a deficit in pain and temperature sensation in a capelike distribution over the shoulders, arms and back is characteristic. Light touch and position and vibration sensation are not affected. Later, spastic leg weakness develops. Deficits may be asymmetric.
Syringobulbia may cause vertigo, nystagmus, unilateral or bilateral loss of facial sensation, lingual atrophy and weakness, dysarthria, dysphagia, hoarseness, and sometimes peripheral sensory or motor deficits due to medullary compression.
Cause
A syrinx results when a watery, protective substance known as cerebrospinal fluid, that normally flows around the spinal cord and brain, transporting nutrients and waste products, collects in a small area of the spinal cord and forms a pseudocyst.
A number of medical conditions can cause an obstruction in the normal flow of cerebrospinal fluid, redirecting it into the spi
|
https://en.wikipedia.org/wiki/Syringobulbia
|
Syringobulbia is a medical condition in which syrinxes, or fluid-filled cavities, affect the brainstem (usually the lower brainstem). The exact cause is often unknown, but may be linked to a widening of the central canal of the spinal cord. This may affect one or more cranial nerves, resulting in various kinds of facial palsies. Sensory and motor nerve pathways may be affected by interruption or compression of nerves. This disorder is associated with syringomyelia, a syrinx limited to the spinal cord. It can be diagnosed using magnetic resonance imaging. Symptoms may be treated with tricyclic antidepressants.
Signs and symptoms
Syringobulbia usually causes pain. It may also cause a loss of sense of temperature. Alveolar hypoventilation (insufficient breathing, a type of central hypoventilation syndrome) may occur, with hypercapnia (excess blood CO2), stridor (an unusual breathing sound), and irregular breathing.
Cause
Syringobulbia may be caused by a birth defect, trauma or tumor growth. The exact trigger is unknown, but may be linked to a widening of the central canal of the spinal cord.
Mechanism
Syringobulbia affects the lower part of the brainstem. The central canal of the spinal cord may be widened. A fluid-filled lesion forms, known as a syrinx. This can vary in size significantly between patients. Nerve fibres may be compressed where they cross the midline, or in other parts of the spinal cord. Cranial nerves may be affected.
Syringobulbia may be associated with

https://en.wikipedia.org/wiki/Antigen%20presentation
|
Antigen presentation is a vital immune process that is essential for T cell immune response triggering. Because T cells recognize only fragmented antigens displayed on cell surfaces, antigen processing must occur before the antigen fragment can be recognized by a T-cell receptor. Specifically, the fragment, bound to the major histocompatibility complex (MHC), is transported to the surface of the cell, a process known as presentation. If there has been an infection with viruses or bacteria, the cell will present an endogenous or exogenous peptide fragment derived from the antigen by MHC molecules. There are two types of MHC molecules which differ in the behaviour of the antigens: MHC class I molecules (MHC-I) bind peptides from the cell cytosol, while peptides generated in the endocytic vesicles after internalisation are bound to MHC class II (MHC-II). Cellular membranes separate these two cellular environments - intracellular and extracellular. Each T cell can only recognize tens to hundreds of copies of a unique sequence of a single peptide among thousands of other peptides presented on the same cell, because an MHC molecule in one cell can bind to quite a large range of peptides. Predicting which (fragments of) antigens will be presented to the immune system by a certain MHC/HLA type is difficult, but the technology involved is improving.

https://en.wikipedia.org/wiki/Cyclic%20pump
|
A Cyclic pump is an apparatus which moves a fluid in a periodic uni-directional direction from one containment system to another while overcoming static conditions that would, without intervention, not move. The intervention predicated by the pump alters pressures, volumes and sometimes temperatures of fluids (gaseous, liquid, colloidal, plasmic, etc.) in such a way that the fluids are transported to other chambers or enclosures (including pipes), thus "flowing" in a consistent direction, usually having characteristics of pulsation (as is the case with the Human heart) or of uniform motion (as is the case with an Automobile motor oil pump). Cyclic pumps are generally incorporated into machines to deal with all sorts of fluids associated with that machine's functionality.

https://en.wikipedia.org/wiki/Duodenal%20cytochrome%20B
|
Duodenal cytochrome B (Dcytb) also known as cytochrome b reductase 1 is an enzyme that in humans is encoded by the gene.
Dcytb CYBRD1 was first identified as a ferric reductase enzyme which catalyzes the reduction of Fe3+ to Fe2+ required for dietary iron absorption in the duodenum of mammals. Dcytb mRNA and protein levels in the gut are increased by iron deficiency and hypoxia which acts to promote dietary iron absorption. The effect of iron deficiency and hypoxia on Dcytb levels are medicated via the HIF2 (Hypoxia inducible factor 2) transcription factor which binds to hypoxia response elements within the Dcytb promoter and increases transcription of the gene. DCYTB protein has also been found in other tissues, such as lung epithelial cells and in the plasma membrane of mature red blood cells of scorbutic species (unable to make ascorbate) such as human and guinea pig but not in other species which have retained the ability to synthesise ascorbate like mice and rat. This has led to the notion that Dcytb may have an additional role in ascorbate metabolism in scorbutic species. DCYTB protein has also been found in breast tissue (epithelial and myoepithelial cells) and high DCYTB levels are associated with a favourable prognosis in patients with breast cancer. A single nucleotide polymorphism (SNP) within the DCYTB promoter (SNP rs884409) which reduced functional DCYTB promoter activity was also associated with reduced serum ferritin levels in a patient cohort with C28

https://en.wikipedia.org/wiki/Scoulerine
|
Scoulerine, also known as discretamine and aequaline, is a benzylisoquinoline alkaloid (BIA) that is derived directly from (S)-reticuline through the action of berberine bridge enzyme. It is a precursor of other BIAs, notably berberine, noscapine, (S)-tetrahydropalmatine, and (S)-stylopine, as well as the alkaloids protopine, and sanguinarine. It is found in many plants, including opium poppy, Croton flavens, and certain plants in the genus Erythrina.
Studies show that scoulerine is an antagonist in vitro at the α2-adrenoceptor, α1D-adrenoceptor and 5-HT receptor. It has also been found to be a GABAA receptor agonist in vitro.
