https://en.wikipedia.org/wiki/Avalanche%20transistor
|
An avalanche transistor is a bipolar junction transistor designed for operation in the region of its collector-current/collector-to-emitter voltage characteristics beyond the collector-to-emitter breakdown voltage, called avalanche breakdown region. This region is characterized by avalanche breakdown, which is a phenomenon similar to Townsend discharge for gases, and negative differential resistance. Operation in the avalanche breakdown region is called avalanche-mode operation: it gives avalanche transistors the ability to switch very high currents with less than a nanosecond rise and fall times (transition times). Transistors not specifically designed for the purpose can have reasonably consistent avalanche properties; for example 82% of samples of the 15V high-speed switch 2N2369, manufactured over a 12-year period, were capable of generating avalanche breakdown pulses with rise time of 350 ps or less, using a 90V power supply as Jim Williams writes.
History
The first paper dealing with avalanche transistors was . The paper describes how to use alloy-junction transistors in the avalanche breakdown region in order to overcome speed and breakdown voltage limitations which affected the first models of such kind of transistor when used in earlier computer digital circuits. Therefore, the very first applications of avalanche transistors were in switching circuits and multivibrators. The introduction of the avalanche transistor served also as an application of Miller's empiric

https://en.wikipedia.org/wiki/Paramutation
|
In epigenetics, a paramutation is an interaction between two alleles at a single locus, whereby one allele induces a heritable change in the other allele. The change may be in the pattern of DNA methylation or histone modifications. The allele inducing the change is said to be paramutagenic, while the allele that has been epigenetically altered is termed paramutable. A paramutable allele may have altered levels of gene expression, which may continue in offspring which inherit that allele, even though the paramutagenic allele may no longer be present. Through proper breeding, paramutation can result in siblings that have the same genetic sequence, but with drastically different phenotypes.
Though studied primarily in maize, paramutation has been described in a number of other systems, including animal systems like Drosophila melanogaster and mice. Despite its broad distribution, examples of this phenomenon are scarce and its mechanism is not fully understood.
History
The first description of what would come to be called paramutation was given by William Bateson and Caroline Pellew in 1915, when they described "rogue" peas that always passed their "rogue" phenotype onto their progeny. However, the first formal description of paramutation was given by R.A. Brink at the University of Wisconsin–Madison in the 1950s, who did his work in maize (Zea mays). Brink noticed that specific weakly expressed alleles of the red1 (r1) locus in maize, which encodes a transcription factor tha

|
The National Institute of Statistics and Censuses (; INDEC) is an Argentine decentralized public body that operates within the Ministry of Economy, which exercises the direction of all official statistical activities carried out in the country.
In February 2013, the International Monetary Fund censured Argentina for failing to report accurate inflation data. Political intervention in the INDEC figures ended, and the IMF declared in November 2016 that Argentine statistics were again in accordance with international standards.
Definition
The National Institute of Statistics and Census (, INDEC) is a public
deconcentrated body, of a technical nature, within the scope of Argentina's National Ministry of Economy, and which runs all the official statistical activities carried out throughout the country.
Its creation and operation are regulated by Law 176221, executive orders 3110/702 and 1831/933, and INDEC Provision 176/99.4 It is a deconcentrated entity within the scope of the Ministry of Treasury of Argentina.
INDEC produces statistical information on Argentina, which can be used by governments for public policy planning. It can also be used for research and projections in the academic and private fields.
Citizen and stakeholder cooperation and contribution of primary data are fundamental in statistical production. Individual data are confidential and are protected by statistical confidentiality established in Law 17622, and results are always published as statistics. Rel

https://en.wikipedia.org/wiki/Protein%20misfolding%20cyclic%20amplification
|
Protein misfolding cyclic amplification (PMCA) is an amplification technique (conceptually like PCR but not involving nucleotides) to multiply misfolded prions originally developed by Soto and colleagues. It is a test for spongiform encephalopathies like CWD or BSE.
Technique
The technique initially incubates a small amount of abnormal prion with an excess of normal protein, so that some conversion takes place. The growing chain of misfolded protein is then blasted with ultrasound, breaking it down into smaller chains and so rapidly increasing the amount of abnormal protein available to cause conversions. By repeating the cycle, the mass of normal protein is rapidly changed into the prion being tested for.
Development
PMCA was originally developed to, in vitro, mimic prion replication with a similar efficiency to the in vivo process, but with accelerated kinetics. PMCA is conceptually analogous to the polymerase chain reaction - in both systems a template grows at the expense of a substrate in a cyclic reaction, combining growing and multiplication of the template units.
Replication
PMCA has been applied to replicate the misfolded protein from diverse species. The newly generated protein exhibits the same biochemical, biological, and structural properties as brain-derived PrPSc and strikingly it is infectious to wild type animals, producing a disease with similar characteristics as the illness produced by brain-isolated prions.

https://en.wikipedia.org/wiki/Retromer
|
Retromer is a complex of proteins that has been shown to be important in recycling transmembrane receptors from endosomes to the trans-Golgi network (TGN) and directly back to the plasma membrane. Mutations in retromer and its associated proteins have been linked to Alzheimer's and Parkinson's diseases.
Background
Retromer is a heteropentameric complex, which in humans is composed of a less defined membrane-associated sorting nexin dimer (SNX1, SNX2, SNX5, SNX6), and a vacuolar protein sorting (Vps) heterotrimer containing Vps26, Vps29, and Vps35. Although the SNX dimer is required for the recruitment of retromer to the endosomal membrane, the cargo binding function of this complex is contributed by the core heterotrimer through the binding of Vps26 and Vps35 subunits to various cargo molecules including M6PR, wntless, SORL1 (which is also a receptor for other cargo proteins such as APP), and sortilin. Early study on sorting of acid hydrolases such as carboxypeptidase Y (CPY) in S. cerevisiae mutants has led to the identification of retromer in mediating the retrograde trafficking of the pro-CPY receptor (Vps10) from the endosomes to the TGN.
Structure
The retromer complex is highly conserved: homologs have been found in C. elegans, mouse and human. The retromer complex consists of 5 proteins in yeast: Vps35p, Vps26p, Vps29p, Vps17p, Vps5p. The mammalian retromer consists of Vps26, Vps29, Vps35, SNX1 and SNX2, and possibly SNX5 and SNX6. It is proposed to act in tw

https://en.wikipedia.org/wiki/Adult%20stem%20cell
|
Adult stem cells are undifferentiated cells, found throughout the body after development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells (from Greek σωματικóς, meaning of the body), they can be found in juvenile, adult animals, and humans, unlike embryonic stem cells.
Scientific interest in adult stem cells is centered around two main characteristics. The first of which is their ability to divide or self-renew indefinitely, and the second their ability to generate all the cell types of the organ from which they originate, potentially regenerating the entire organ from a few cells. Unlike embryonic stem cells, the use of human adult stem cells in research and therapy is not considered to be controversial, as they are derived from adult tissue samples rather than human embryos designated for scientific research. The main functions of adult stem cells are to replace cells that are at risk of possibly dying as a result of disease or injury and to maintain a state of homeostasis within the cell. There are three main methods to determine if the adult stem cell is capable of becoming a specialized cell. The adult stem cell can be labeled in vivo and tracked, it can be isolated and then transplanted back into the organism, and it can be isolated in vivo and manipulated with growth hormones. They have mainly been studied in humans and model organisms such as mice and rats.

In mathematics, mathematical physics, and theoretical physics, the spin tensor is a quantity used to describe the rotational motion of particles in spacetime. The spin tensor has application in
general relativity and special relativity, as well as quantum mechanics, relativistic quantum mechanics, and quantum field theory.
The special Euclidean group SE(d) of direct isometries is generated by translations and rotations. Its Lie algebra is written .
This article uses Cartesian coordinates and tensor index notation.
Background on Noether currents
The Noether current for translations in space is momentum, while the current for increments in time is energy. These two statements combine into one in spacetime: translations in spacetime, i.e. a displacement between two events, is generated by the four-momentum P. Conservation of four-momentum is given by the continuity equation:
where is the stress–energy tensor, and ∂ are partial derivatives that make up the four-gradient (in non-Cartesian coordinates this must be replaced by the covariant derivative). Integrating over space:
gives the four-momentum vector at time t.
The Noether current for a rotation about the point y is given by a tensor of 3rd order, denoted . Because of the Lie algebra relations
where the 0 subscript indicates the origin (unlike momentum, angular momentum depends on the origin), the integral:
gives the angular momentum tensor at time t.

https://en.wikipedia.org/wiki/Quarter-pixel%20motion
|
Quarter-pixel motion (also known as Q-pel motion or Qpel motion) refers to using a quarter of the distance between pixels (or luma sample positions) as the motion vector precision for motion estimation and motion compensation in video compression schemes. It is used in many modern video coding formats such as MPEG-4 ASP, H.264/AVC, and HEVC. Though higher precision motion vectors take more bits to encode, they can sometimes result in more efficient compression overall, by increasing the quality of the prediction signal.
Operation
Video encoding software products such as Xvid, 3ivx, and DivX Pro Codec, which are based upon the MPEG-4 specification, use motion estimation algorithms to significantly improve video compression. The default level of resolution for motion estimation for most MPEG-4 ASP implementations is half a pixel, although quarter pixel is specified under the standard. H.264 decoders always support quarter-pixel motion. Quarter-pixel resolution can improve the quality of the video prediction signal as compared to half-pixel resolution, although the improvement may not always be enough to offset the increased bit cost of the quarter-pixel-precision motion vector; additional techniques such as rate-distortion optimization, which takes both quality and bit cost into account, are used to significantly improve the effectiveness of quarter-pel motion estimation.
Interpolation methods
Quarter-pixel motion compensation, much like half-pixel, is achieved through int

https://en.wikipedia.org/wiki/Reticular%20fiber
|
Reticular fibers, reticular fibres or reticulin is a type of fiber in connective tissue composed of type III collagen secreted by reticular cells. They are mainly composed reticulin protein and form a network or mesh. Reticular fibers crosslink to form a fine meshwork (reticulin). This network acts as a supporting mesh in soft tissues such as liver, bone marrow, and the tissues and organs of the lymphatic system.
History
The term reticulin was coined in 1892 by M. Siegfried.
Today, the term reticulin or reticular fiber is restricted to referring to fibers composed of type III collagen. However, during the pre-molecular era, there was confusion in the use of the term reticulin, which was used to describe two structures:
the argyrophilic (silver staining) fibrous structures present in basement membranes
histologically similar fibers present in developing connective tissue.
The history of the reticulin silver stain is reviewed by Puchtler et al. (1978). The abstract of this paper says:
Maresch (1905) introduced Bielschowsky's silver impregnation technic for neurofibrils as a stain for reticulum fibers, but emphasized the nonspecificity of such procedures. This lack of specificity has been some confirmed repeatedly. Yet, since the 1920s the definition of "reticulin" and studies of its distribution were based solely on silver impregnation technics. The chemical mechanism and specificity of this group of stains is obscure. Application of Gömöri's and Wilder's methods to human t

https://en.wikipedia.org/wiki/Natural%20bobtail
|
A natural bobtail is an animal's tail which due to a mutated gene grows unusually short or is missing completely. The genes for the shortened tail may be dominant or recessive.
Because of legislation restricting or preventing docking, natural bobtails are growing in popularity among the dog fancy for some traditionally docked breeds. For example, one Boxer breeder and geneticist in England has successfully petitioned the Kennel Club for permission to cross Corgis into his lines and then backcross to Boxers, introducing the gene into his lines. This would have been unheard of in decades past. A number of these bobtail Boxers have been exported to various countries around the world.
However in some breeds, such as the Rottweiler, natural bobtails are not universally accepted in the Country of Origin Breed Standard.

Victor John Emery (16 May 1934 – 18 July 2002) was a British specialist on superconductors and superfluidity. His model for the electronic structure of the copper-oxide planes is the starting point for many analyses of high-temperature superconductors and is commonly known as the Emery model.
Biography
Early life
Emery was born in Boston, Lincolnshire, England, where he was educated at Staniland School and Boston Grammar School. He won the Parry Gold Medal for the best scholar in 1951 before going on to study physics at the University of Hull, the University of London and the University of Manchester, where he gained a PhD in Theoretical Physics.
At school Emery was a keen swimmer and the star goal-scorer of the Boston water polo team. He also won the town's one mile swimming race on the River Witham on more than one occasion
Career in Theoretical Physics
After completing his studies at Manchester he spent two years as a research associate at Cavendish Laboratory in Cambridge. He was a Fellow at the University of California, Berkeley until 1960. While at Berkeley in 1960, together with Andrew Sessler, he made the prediction that liquid helium-3 would experience superfluidity, flowing without friction, at temperatures very close to absolute zero. The theory was later confirmed experimentally. At this stage he returned to the United Kingdom where he spent some time as a lecturer at the University of Birmingham.
As a result of his work at Berkeley, Emery was invited to join

Parnassiaceae Gray were a family of flowering plants in the eudicot order Celastrales. The family is not recognized in the APG III system of plant classification. When that system was published in 2009, Parnassiaceae were treated as subfamily Parnassioideae of an expanded family Celastraceae.
Parnassiaceae have only two genera, Lepuropetalon and Parnassia. Lepuropetalon has only one species, Lepuropetalon spathulatum, a winter annual that usually prefers sandy soil. It is one of the smallest of flowering plants, up to 2 cm tall. Lepuropetalon has a disjunct distribution, being known from the southeastern United States and central Chile, but is probably far more common than has been reported.
Parnassia is a genus of perennial herbs, up to 60 cm tall, that grow in bogs, marshes, and other wet areas, mostly in cool to cold climates of the north temperate zone. There are at least 70 species. Sixty-three species occur in China and 49 of these occur nowhere else. A second area of diversity for Parnassia is North America and about 9 species occur there. Parnassia palustris is the most well known and widely distributed species. It ranges through most of northern Eurasia, Canada, and the western United States. Parnassia palustris is widely cultivated. About 10 species are known in cultivation, all as ornamentals.

Telugu Brahmins are Telugu-speaking Brahmin communities native to the Indian states of Andhra Pradesh and Telangana. They fall under the Pancha Dravida Brahmin classification of the Brahmin community in India. Telugu Brahmins are further divided into sections like Vaidiki, Niyogi, Deshastha, Dravida and Golkonda Vyapari.
History
According to the Aitareya Brahmana of the Rigveda, the Andhras left north India from the banks of the River Yamuna around 800 BCE and migrated to peninsular India.
The Apastamba Dharmasutra is posited to have been composed in the region of modern-day Andhra Pradesh between the Godavari and Krishna rivers, but this is not certain. It is dated to approximately 600-300 BCE, and more narrowly to between 450 and 350 BCE.
Sub-divisions
Telugu Brahmins fall under the Pancha Dravida Brahmin classification of the Brahmin community in India. They are further divided into various sections based on their occupation, denomination, region etc.
Sub-groups
Vaidiki (Velanati, Telaganya, Mulukanadu), Niyogi (Aruvela, Pakanati, Prathamasaki etc.), Golkonda Vyapari, Deshastha and Dravida.
Denominational divisions
Smartha, Madhva, Vaikhanasa, Sri Vaishnava, Shaiva and Shakta.
Even though in Andhra Pradesh and Telangana regions majority of Vaidikis and Niyogis are Smartas, who follow Advaita Vedanta of Adi Shankara, there are some sections among them who migrated and settled in Karnataka and Tamil Nadu region that follow Dvaita Vedanta of Madhvacharya.

Dotfuscator is a tool performing a combination of code obfuscation, optimization, shrinking, and hardening on .NET, Xamarin and Universal Windows Platform apps. Ordinarily, .NET executables can easily be reverse engineered by free tools (such as ILSpy, dotPeek and JustDecompile), potentially exposing algorithms and intellectual property (trade secrets), licensing and security mechanisms. Also, code can be run through a debugger and its data inspected. Dotfuscator can make all of these things more difficult.
Dotfuscator was developed by PreEmptive Solutions. A free version of the .NET Obfuscator, called the Dotfuscator Community Edition, is distributed as part of Microsoft's Visual Studio. However, the current version is free for personal, non-commercial use only.

In mathematics, Mostow's rigidity theorem, or strong rigidity theorem, or Mostow–Prasad rigidity theorem, essentially states that the geometry of a complete, finite-volume hyperbolic manifold of dimension greater than two is determined by the fundamental group and hence unique. The theorem was proven for closed manifolds by and extended to finite volume manifolds by in 3 dimensions, and by in all dimensions at least 3. gave an alternate proof using the Gromov norm. gave the simplest available proof.
While the theorem shows that the deformation space of (complete) hyperbolic structures on a finite volume hyperbolic -manifold (for ) is a point, for a hyperbolic surface of genus there is a moduli space of dimension that parameterizes all metrics of constant curvature (up to diffeomorphism), a fact essential for Teichmüller theory. There is also a rich theory of deformation spaces of hyperbolic structures on infinite volume manifolds in three dimensions.
The theorem
The theorem can be given in a geometric formulation (pertaining to finite-volume, complete manifolds), and in an algebraic formulation (pertaining to lattices in Lie groups).
Geometric form
Let be the -dimensional hyperbolic space. A complete hyperbolic manifold can be defined as a quotient of by a group of isometries acting freely and properly discontinuously (it is equivalent to define it as a Riemannian manifold with sectional curvature -1 which is complete).

The South East London Green Chain, also known as the Green Chain Walk, is a linked system of open spaces between the River Thames and Crystal Palace Park in London, England. In 1977 four London boroughs and the Greater London Council created this Green Chain of 300 open spaces to protect them from building activity. The four London boroughs are Bexley, Bromley, Lewisham and Greenwich. More recently it has been extended to include sections in Southwark. Many parts of the system are also part of the Capital Ring route.
The system begins at three places on the River Thames: Thames Barrier, Thamesmead, and the riverside at Erith. There are various circular walks along the route, and there is an offshoot from the main route to Chislehurst; and the next section reaches Crystal Palace via Bromley.
From there it goes north with branches to Dulwich and Nunhead.
The major open spaces in the Chain are:
Lesnes Abbey
Bostall Heath and Woods
Parks in Charlton including Maryon Park, Maryon Wilson Park and Charlton Park

|
In mathematics, the Poincaré–Bendixson theorem is a statement about the long-term behaviour of orbits of continuous dynamical systems on the plane, cylinder, or two-sphere.
Theorem
Given a differentiable real dynamical system defined on an open subset of the plane, every non-empty compact ω-limit set of an orbit, which contains only finitely many fixed points, is either
a fixed point,
a periodic orbit, or
a connected set composed of a finite number of fixed points together with homoclinic and heteroclinic orbits connecting these.
Moreover, there is at most one orbit connecting different fixed points in the same direction. However, there could be countably many homoclinic orbits connecting one fixed point.
A weaker version of the theorem was originally conceived by , although he lacked a complete proof which was later given by .
Discussion
The condition that the dynamical system be on the plane is necessary to the theorem. On a torus, for example, it is possible to have a recurrent non-periodic orbit.
In particular, chaotic behaviour can only arise in continuous dynamical systems whose phase space has three or more dimensions. However the theorem does not apply to discrete dynamical systems, where chaotic behaviour can arise in two- or even one-dimensional systems.
Applications
One important implication is that a two-dimensional continuous dynamical system cannot give rise to a strange attractor. If a strange attractor C did exist in such a system, then it could be e

https://en.wikipedia.org/wiki/Microfibril
|
A microfibril is a very fine fibril, or fiber-like strand, consisting of glycoproteins and cellulose. It is usually, but not always, used as a general term in describing the structure of protein fiber, e.g. hair and sperm tail. Its most frequently observed structural pattern is the 9+2 pattern in which two central protofibrils are surrounded by nine other pairs. Cellulose inside plants is one of the examples of non-protein compounds that are using this term with the same purpose. Cellulose microfibrils are laid down in the inner surface of the primary cell wall. As the cell absorbs water, its volume increases and the existing microfibrils separate and new ones are formed to help increase cell strength.
Synthesis and function
Cellulose is synthesized by cellulose synthase or Rosette terminal complexes which reside on a cells membrane. As cellulose fibrils are synthesized and grow extracellularly they push up against neighboring cells. Since the neighboring cell can not move easily the Rosette complex is instead pushed around the cell through the fluid phospholipid membrane. Eventually this results in the cell becoming wrapped in a microfibril layer. This layer becomes the cell wall. The organization of microfibrils forming the primary cell wall is rather disorganized. However, another mechanism is used in secondary cell walls leading to its organization. Essentially, lanes on the secondary cell wall are built with microtubules. These lanes force microfibrils to remain in a

In mathematics, a mixed boundary condition for a partial differential equation defines a boundary value problem in which the solution of the given equation is required to satisfy different boundary conditions on disjoint parts of the boundary of the domain where the condition is stated. Precisely, in a mixed boundary value problem, the solution is required to satisfy a Dirichlet or a Neumann boundary condition in a mutually exclusive way on disjoint parts of the boundary.
For example, given a solution to a partial differential equation on a domain with boundary , it is said to satisfy a mixed boundary condition if, consisting of two disjoint parts, and , such that , verifies the following equations:

The mixed boundary condition differs from the Robin boundary condition in that the latter requires a linear combination, possibly with pointwise variable coefficients, of the Dirichlet and the Neumann boundary value conditions to be satisfied on the whole boundary of a given domain.
Historical note
The first boundary value problem satisfying a mixed boundary condition was solved by Stanisław Zaremba for the Laplace equation: according to himself, it was Wilhelm Wirtinger who suggested him to study this problem.

https://en.wikipedia.org/wiki/Imbibition
|
Imbibition is a special type of diffusion that takes place when liquid is absorbed by solids-colloids causing an increase in volume. Water surface potential movement takes place along a concentration gradient; some dry materials absorb water. A gradient between the absorbent and the liquid is essential for imbibition. For a substance to imbibe a liquid, there must first be some attraction between them. Imbibition occurs when a wetting fluid displaces a non-wetting fluid, the opposite of drainage in which a non-wetting phase displaces the wetting fluid. The two processes are governed by different mechanisms. Imbibition is also a type of diffusion since water movement is along the concentration gradient. Seeds and other such materials have almost no water hence they absorb water easily. Water potential gradient between the absorbent and liquid imbibed is essential for imbibition.
Examples
One example of imbibition in nature is the absorption of water by hydrophilic colloids. Matrix potential contributes significantly to water in such substances. Dry seeds germinate in part by imbibition. Imbibition can also control circadian rhythms in Arabidopsis thaliana and (probably) other plants. The Amott test employs imbibition.
Proteins have high imbibition capacities, so proteinaceous pea seeds swell more than starchy wheat seeds.
Imbibition of water increases imbibant volume, which results in imbibitional pressure (IP). The magnitude of such pressure can be demonstrated by the s

|
In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage. It consists of all the components in the receiver that process the signal at the original incoming radio frequency (RF), before it is converted to a lower intermediate frequency (IF). In microwave and satellite receivers it is often called the low-noise block downconverter (LNB) and is often located at the antenna, so that the signal from the antenna can be transferred to the rest of the receiver at the more easily handled intermediate frequency.
Superheterodyne receiver
For most superheterodyne architectures, the RF front end consists of:
A band-pass filter (BPF) to reduce image response. This removes any signals at the image frequency, which would otherwise interfere with the desired signal. It also prevents strong out-of-band signals from saturating the input stages.
An RF amplifier, often called the low-noise amplifier (LNA). Its primary responsibility is to increase the sensitivity of the receiver by amplifying weak signals without contaminating them with noise, so that they can stay above the noise level in succeeding stages. It must have a very low noise figure (NF). The RF amplifier may not be needed and is often omitted (or switched off) for frequencies below 30 MHz, where the signal-to-noise ratio is defined by atmospheric and human-made noise.

https://en.wikipedia.org/wiki/Numerical%20resistivity
|
Numerical resistivity is a problem in computer simulations of ideal magnetohydrodynamics (MHD). It is a form of numerical diffusion. In near-ideal MHD systems, the magnetic field can diffuse only very slowly through the plasma or fluid of the system; it is rate-limited by the inverse of the resistivity of the fluid. In Eulerian simulations where the field is arbitrarily aligned compared to the simulation grid, the numerical diffusion rate takes the form similar to an additional resistivity, causing non-physical and sometimes bursty magnetic reconnection in the simulation. Numerical resistivity is a function of resolution, alignment of the magnetic field with the grid, and numerical method. In general, numerical resistivity will not behave isotropically, and there can be different effective numerical resistivities in different parts of the computational domain. For current (2005) simulations of the solar corona and inner heliosphere, this numerical effect can be several orders of magnitude larger than the physical resistivity of the plasma.

https://en.wikipedia.org/wiki/Numerical%20diffusion
|
Numerical diffusion is a difficulty with computer simulations of continua (such as fluids) wherein the simulated medium exhibits a higher diffusivity than the true medium. This phenomenon can be particularly egregious when the system should not be diffusive at all, for example an ideal fluid acquiring some spurious viscosity in a numerical model.
Explanation
In Eulerian simulations, time and space are divided into a discrete grid and the continuous differential equations of motion (such as the Navier–Stokes equation) are discretized into finite-difference equations. The discrete equations are in general more diffusive than the original differential equations, so that the simulated system behaves differently than the intended physical system. The amount and character of the difference depends on the system being simulated and the type of discretization that is used. Most fluid dynamics or magnetohydrodynamic simulations seek to reduce numerical diffusion to the minimum possible, to achieve high fidelity — but under certain circumstances diffusion is added deliberately into the system to avoid singularities. For example, shock waves in fluids and current sheets in plasmas are in some approximations infinitely thin; this can cause difficulty for numerical codes. A simple way to avoid the difficulty is to add diffusion that smooths out the shock or current sheet. Higher order numerical methods (including spectral methods) tend to have less numerical diffusion than low or

https://en.wikipedia.org/wiki/Derivative%20suit
|
A shareholder derivative suit is a lawsuit brought by a shareholder on behalf of a corporation against a third party. Often, the third party is an insider of the corporation, such as an executive officer or director. Shareholder derivative suits are unique because under traditional corporate law, management is responsible for bringing and defending the corporation against suit. Shareholder derivative suits permit a shareholder to initiate a suit when management has failed to do so. To enable a diversity of management approaches to risks and reinforce the most common forms of corporate rules with a high degree of permissible management power, many jurisdictions have implemented minimum thresholds and grounds (procedural and substantive) to such suits.
Purpose and difficulties
Under traditional corporate business law, shareholders are the owners of a corporation. However, they are not empowered to control the day-to-day operations of the corporation. Instead, shareholders appoint directors, and the directors in turn appoint officers and/or relatively less powerful executives to manage day-to-day operations.
Derivative suits refer to one or more shareholders bringing an action (lawsuit) in the name of the corporation against a party or parties allegedly causing harm to the latter. If the directors, officers, or employees of the corporation are not willing to file an action, a shareholder may first petition them to proceed. If such petition fails, they may take it upon themself

|
Acute intermittent porphyria (AIP) is a rare metabolic disorder affecting the production of heme resulting from a deficiency of the enzyme porphobilinogen deaminase. It is the most common of the acute porphyrias.
Signs and symptoms
The clinical presentation of AIP is highly variable and non-specific. The patients are typically asymptomatic, with most gene carriers having no family history because the condition had remained latent for several generations. The syndrome marked by acute attacks affects only 10% of gene carriers. The mean age at diagnosis is 33 years old. Like other porphyrias, AIP is more likely to present in women. A distinguishing feature of AIP that separates it from other porphyrias is the absence of photosensitive cutaneous symptoms that occur in addition to acute attacks.
Acute attacks
AIP is one of the four porphyrias that presents as an acute attack. 90% of affected individuals never experience an acute attack and are asymptomatic, while an estimated 5% of affected individuals experience repeat attacks. Attacks are most common in young adult women and are rare before puberty or after menopause. Severe acute attacks may require hospitalization. Patients usually experience symptoms in attacks that last from several hours to a few days. Between attacks, patients are asymptomatic.
The most frequent presenting symptoms are abdominal pain and tachycardia. The abdominal pain is typically severe, colicky, poorly localized, and often associated with pain in ba

https://en.wikipedia.org/wiki/NOX2
|
NADPH oxidase 2 (Nox2), also known as cytochrome b(558) subunit beta or Cytochrome b-245 heavy chain, is a protein that in humans is encoded by the NOX2 gene (also called CYBB gene). The protein is a superoxide generating enzyme which forms reactive oxygen species (ROS).
Function
The CYBB gene encode cytochrome b-245, beta chain. This protein is subunit of a group of proteins that forms an enzyme complex called NADPH oxidase, which plays an essential role in the immune system. Within this complex, the cytochrome b-245, beta chain has an alpha chain partner (produced from the CYBA gene). Both alpha and beta chains are required for either to function and the NADPH oxidase complex requires both chains in order to be functional. It has been proposed as a primary component of the microbicidal oxidase system of phagocytes.
Nox2 is the catalytic, membrane-bound subunit of NADPH oxidase. It is inactive until it binds to the membrane-anchored p22phox, forming the heterodimer known as flavocytochrome b558. After activation, the regulatory subunits p67phox, p47phox, p40phox and a GTPase, typically Rac, are recruited to the complex to form NADPH oxidase on the plasma membrane or phagosomal membrane. Nox2 itself is composed of an N-terminal transmembrane domain that binds two heme groups, and a C-terminal domain that is able to bind to FAD and NADPH.
Evidence has shown that it plays an important role in atherosclerotic lesion development in the aortic arch, thoracic, and abdominal ao

https://en.wikipedia.org/wiki/Topple%20rate
|
Topple rate is measure of how often the leading companies in a particular industry changes. It is defined as the probability that a firm in the industry, already in the top 20% in revenue, will drop out of this revenue leadership position within the next five years. The topple rate is one method of measuring overall competition in a particular industry; higher topple rates are often viewed as indicating a strong market with healthy economic activity. The term's invention is credited to McKinsey consultant Patrick Viguerie.
Modern industries have increasingly taken advantage of advances in technology and globalization to drive significant increases in productivity, but these changes also more easily enable new competitors and new innovations. These competitors often have lower costs, lower return requirements, or cheaper or imitation products. Topple rates across all industries doubled between 1972 and 2002, even when controlling for acquisitions of previous industry leaders; including them in the data showed that the overall rate actually tripled. At the peak of the Great Depression in 1937, companies listed on the S&P 500 had an average lifespan of 75 years. By 2011, that figure had fallen to 18 years, a reduction in lifespan of 76%.
In 2011, a study by Deloitte of 20,000 firms from 1965 to 2010 showed an overall doubling of the topple rate, though the effect occurred at different speeds across various industries. Those least affected by the increase in topple rate tended

Robert Harding Whittaker (December 27, 1920 – October 20, 1980) was an American plant ecologist, active in the 1950s to the 1970s. He was the first to propose the five kingdom taxonomic classification of the world's biota into the Animalia, Plantae, Fungi, Protista, and Monera in 1969. He also proposed the Whittaker Biome Classification, which categorized biome-types upon two abiotic factors: temperature and precipitation.
Whittaker was elected to the National Academy of Sciences in 1974, received the Ecological Society of America's Eminent Ecologist Award in 1981, and was otherwise widely recognized and honored. He collaborated with many other ecologists including George Woodwell (Dartmouth), W. A. Niering, F. H. Bormann (Yale) and G. E. Likens (Cornell), and was particularly active in cultivating international collaborations.
Early life
Born in Wichita, Kansas, he obtained a B.A. at Washburn Municipal College (now Washburn University) in Topeka, Kansas, and, following military service, his Ph.D. in Biology at the University of Illinois in 1948.
Career
Whittaker held teaching and research positions at Washington State College in Pullman, Washington from 1948 to 1951, and then moved Hanford Laboratories Aquatic Biology
Unit near Richland, Washington. In 1954, he was hired as an instructor in the Department of Biology of Brooklyn College, the City University of New York. In the 1960s, he worked at the University of California, Irvine and Cornell University.

|
Herbert Rees Wilson FRSE (20 March 1929 – 22 May 2008) was a physicist, who was one of the team who worked on the structure of DNA at King's College London, under the direction of Sir John Randall.
Biography
Early life
He was born the son of a sea captain at Nefyn on the Llŷn Peninsula and educated at Nefyn school and Pwllheli Grammar School. He entered Bangor University, where he gained a first class honours degree in physics in 1949 and a PhD in 1952 under the supervision of professor Edwin Owen.
College education
Having received a University of Wales fellowship, Wilson joined Maurice Wilkins at King's College London in September 1952. The work involved X-ray diffraction studies of DNA, nucleoproteins and cell nuclei. Prior to the double helix model, their studies showed that DNAs from different sources (including biologically active transforming principle) had essentially the same structure, and confirmed that the phosphate groups were on the outside of the molecule.
Scientific discoveries and achievements
Three papers were published in Nature, April 1953, to announce a structure for DNA. Maurice Wilkins, Alex Stokes and Wilson published their paper in the same issue as the paper from Rosalind Franklin and Raymond Gosling, and the paper by Francis Crick and James Watson. The 1962 Nobel Prize for Physiology or Medicine was subsequently jointly awarded to Francis Crick, James Watson, and Maurice Wilkins.

George Alfred Barnard (23 September 1915 – 9 August 2002) was a British statistician known particularly for his work on the foundations of statistics and on quality control.
Early life and education
George Barnard was born in Walthamstow, London. His father was a cabinet maker and his mother had been a domestic servant. His sister Dorothy Wedderburn became a sociologist and eventually Principal of Royal Holloway, University of London. Barnard attended the local grammar school, the Monoux School, and from there he won a scholarship to St John's College, Cambridge, to read mathematics. In 1937 he went on to Princeton University to do graduate work on mathematical logic with Alonzo Church.
Career
Barnard was on holiday in Britain when the Second World War started and he never went back to Princeton to finish his PhD. The war made Barnard into a statistician as it did for many mathematicians of his generation. In 1940 he joined an engineering firm, Plessey, as a mathematical consultant. In 1942 he moved to the Ministry of Supply to apply quality control and sampling methods to the products for which they were responsible. It was there that Barnard began doing statistics. The group he was put in charge of included Peter Armitage, Dennis Lindley and Robin Plackett. Lindley recalls that they were like students working for a doctorate with Barnard as supervisor. Abraham Wald was in a similar group in the United States. Both groups developed sequential methods of sampling.

The Tronado Machine was a device which employed ultra high frequency or microwave radiation as a hyperthermia therapy for cancer; however, tests have failed to back its treatment claims. A man named Tronado designed the machine in the 1970s.
The treatment was improved and a new type of machine built by Dr John Holt who was formerly Head of Oncology at Sir Charles Gairdner Hospital, Perth, Western Australia. He later established an independent clinic in West Perth. After Holt's retirement the clinic moved to Claremont where a research institute was established alongside the clinic. A further treating facility was established by Dr Hugh Tinsley in Dublin, Ireland. This clinic and the treatment were assessed by the Irish government and the clinic received government grants to assist with the ongoing costs of establishment.
Lack of scientific validation
Tests conducted on behalf of the National Health and Medical Research Council of Australia have concluded that UHF Radiowave therapy produces no therapeutic benefit when used in conjunction with conventional cancer treatment. The report Review of the Use of Microwave Therapy for the Treatment of Patients with Cancer conducted a review of the literature as well as an audit of Dr. Holt's patient records between 1973 and 2003. Regarding the literature review, the report stated "There is currently no published scientific evidence that shows benefit of UHF cancer therapy alone or when combined with ‘glucose-blocking agents’ (GBA) as

The Land of the Mountain and the Flood is a concert overture for orchestra, composed by Hamish MacCunn in 1887 and first performed at the Crystal Palace on 5 November of that year. The title is taken from Scott's The Lay of the Last Minstrel, canto vi, stanza 2:
O Caledonia! stern and wild,
Meet nurse for a poetic child!
Land of the heath and shaggy wood,
Land of the mountain and the flood,
Land of my sires! what mortal hand
Can e'er untie the filial band
That knits me to thy rugged strand!
After the premiere The Musical Times commented, "The work – which is spirited and bold in conception and brilliantly scored – was finely played and enthusiastically received". After an 1890 performance at the Crystal Palace, Bernard Shaw wrote of the piece:
In 1968, the overture came to renewed attention when EMI included it on an LP "Music of the Four Countries" (ASD 2400), played by the Scottish National Orchestra conducted by Alexander Gibson. It gained wider familiarity by being used from 1973 to 1976 as the theme for the BBC television series Sutherland's Law.

https://en.wikipedia.org/wiki/Subtelomere
|
Subtelomeres are segments of DNA between telomeric caps and chromatin.
Structure
Telomeres are specialized protein–DNA constructs present at the ends of eukaryotic chromosomes, which prevent them from degradation and end-to-end chromosomal fusion. Most vertebrate telomeric DNA consists of long (TTAGGG)n repeats of variable length, often around 3-20kb. Subtelomeres are segments of DNA between telomeric caps and chromatin. In vertebrates, each chromosome has two subtelomeres immediately adjacent to the long (TTAGGG)n repeats. Subtelomeres are considered to be the most distal (farthest from the centromere) region of unique DNA on a chromosome, and they are unusually dynamic and variable mosaics of multichromosomal blocks of sequence. The subtelomeres of such diverse species as humans, Plasmodium falciparum, Drosophila melanogaster, and Saccharomyces cerevisiae are structurally similar in that they are composed of various repeated elements, but the extent of the subtelomeres and the sequence of the elements vary greatly among organisms. In yeast (S. cerevisiae), subtelomeres are composed of two domains: the proximal and distal (telomeric) domains. The two domains differ in sequence content and extent of homology to other chromosome ends, and they are often separated by a stretch of degenerate telomere repeats (TTAGGG) and an element called 'core X', which is found at all chromosome ends and contains an autonomously replicating sequence (ARS) and an ABF1 binding site.

https://en.wikipedia.org/wiki/Glycogen%20synthase
|
Glycogen synthase (UDP-glucose-glycogen glucosyltransferase) is a key enzyme in glycogenesis, the conversion of glucose into glycogen. It is a glycosyltransferase () that catalyses the reaction of UDP-glucose and (1,4-α-D-glucosyl)n to yield UDP and (1,4-α-D-glucosyl)n+1.
Structure
Much research has been done on glycogen degradation through studying the structure and function of glycogen phosphorylase, the key regulatory enzyme of glycogen degradation. On the other hand, much less is known about the structure of glycogen synthase, the key regulatory enzyme of glycogen synthesis. The crystal structure of glycogen synthase from Agrobacterium tumefaciens, however, has been determined at 2.3 A resolution. In its asymmetric form, glycogen synthase is found as a dimer, whose monomers are composed of two Rossmann-fold domains. This structural property, among others, is shared with related enzymes, such as glycogen phosphorylase and other glycosyltransferases of the GT-B superfamily. Nonetheless, a more recent characterization of the Saccharomyces cerevisiae (yeast) glycogen synthase crystal structure reveals that the dimers may actually interact to form a tetramer. Specifically, The inter-subunit interactions are mediated by the α15/16 helix pairs, forming allosteric sites between subunits in one combination of dimers and active sites between subunits in the other combination of dimers. Since the structure of eukaryotic glycogen synthase is highly conserved among species, glycoge

The Kresta II class, Soviet designation Project 1134A Berkut A (golden eagle), was a class of guided missile cruiser (large anti-submarine warfare ship in Soviet classification) built by the Soviet Union for the Soviet Navy. The NATO lists the class as "cruisers" mainly due to the Metel (SS-N-14 Silex) anti-ship missile system capable to strike not only submarines but also surface vessels.
Design
The Kresta II class was an anti-submarine derivative of the , and were armed with a new anti-submarine missile (SS-N-14), new surface-to-air missiles (SA-N-3) and advanced sonar. Conway's states that the first three ships were to have been armed with the SS-N-9 anti-ship missile but Soviet naval doctrine changed with greater emphasis on anti-submarine warfare. The surface-to-air missiles comprised more advanced SA-N-3 missiles with two twin launchers. New 3D search radar and new fire control radars were also fitted. 4 30mm CIWS guns were also fitted for improved anti-missile defence. A more advanced sonar led to the bow being more sharply raked. The machinery suite comprised two TV-12 steam turbines with high-pressure boilers, identical to the Kresta I class.
General characteristics
The Kresta II-class cruisers were long with a beam of and a draught of . They displaced 6000 tons standard and 7800 full load. They had a complement of 380-400 and were equipped with a hangar aft to stow away a Kamov Ka-25 Hormone-A helicopter.

The Kara class, Soviet designation Project 1134B Berkut B (golden eagle), was a class of guided missile cruisers (large anti-submarine warfare ship in Soviet classification) built in the Soviet Union for the Soviet Navy. The NATO lists the class as "cruisers" mainly due to the Metel (SS-N-14 Silex) anti-ship missile system capable of striking not only submarines, but also surface vessels.
Design
These ships were enlarged versions of the , with gas turbine engines replacing the steam turbines. These ships were fitted as flagships with improved command, control and communications facilities. These are dedicated ASW ships with significant anti-aircraft capability including both M-11 Shtorm and 9K33 Osa surface-to-air missiles.
The specifications for the class were issued in 1964 with the design being finalised in the late 1960s. The gas turbine engine was chosen instead of steam for greater efficiency and quietness, and because the main Soviet gas turbine plant had a long association with the Nikolayev shipyards.
The cruiser Azov was constructed as a trials ship for the S-300 missile system and was also fitted with the associated Top Dome Radar. During the Cold War she was confined to the Black Sea.
Ships
All the ships were built by the 61 Communards Shipyard in Mykolaiv (Nikolayev).

Runaway is a 1984 American science fiction action film written and directed by Michael Crichton, starring Tom Selleck, Gene Simmons, Cynthia Rhodes and Kirstie Alley. Selleck portrays a police officer assigned to track down dangerous robots, while Simmons is a scientist who hopes to profit from his manipulation of robots. The film was a box office disappointment and received mixed reviews.
Plot
In the near future, robots are commonplacea part of everyday life like any other electrical applianceand are just as prone to malfunctions. When a robot malfunctions, it could pose a threat to people or property. Such robots are known as "runaways". Since they are more dangerous than the average machine, they are handled by a division of the police trained in robotics. The "runaway" squad, however, is treated as an easy and unexciting assignment, and often ridiculed.
Sgt. Jack R. Ramsay is a veteran police officer who joined the runaway squad after an incident in which his fear of heights allowed a criminal to escape, which subsequently resulted in a family's death at the hands of that escaped criminal. After years on the job, Ramsay has found himself one of the division's few real experts. His new partner Karen Thompson is enthusiastic about the job, but he assures her there is little excitement involved, saying that mostly it involves flipping a switch. This changes when they find themselves handling a new threatthe first robotic homicide. Investigating a household robot that murd

The Rock Island allocation of 98.9 MHz represents many milestones in Quad Cities' radio broadcasting. First, it was the first FM station to originate in the area, signing on as WHBF-FM on October 28, 1947. It was owned by the Rock Island Argus.
Second, WHBF-FM became the area's first radio station to broadcast in stereo, implementing the technology in 1958. Stereo multiplexing followed in 1961, with automation coming a few years later.
WHBF-FM's first home was the Harms Hotel, where it broadcast alongside sister station WHBF. As with most FM stations of the era, WHBF either duplicated the AM station's programming or used a classical music/easy listening format. WHBF-TV joined the fold in July 1950, with all three facilities housed in the Telco Building in downtown Rock Island. All three stations were owned by the Potter family of Rock Island, the same family that published the Rock Island Argus.
In the early 1970s, WHBF moved away from its classical/easy listening format, and for a short while, shared WHBF-AM's middle-of-the-road (MOR) format. When WHBF-AM began its country music format in 1974, WHBF-FM c

|
In number theory, Brun's theorem states that the sum of the reciprocals of the twin primes (pairs of prime numbers which differ by 2) converges to a finite value known as Brun's constant, usually denoted by B2 . Brun's theorem was proved by Viggo Brun in 1919, and it has historical importance in the introduction of sieve methods.
Asymptotic bounds on twin primes
The convergence of the sum of reciprocals of twin primes follows from bounds on the density of the sequence of twin primes.
Let denote the number of primes p ≤ x for which p + 2 is also prime (i.e. is the number of twin primes with the smaller at most x). Then, we have
That is, twin primes are less frequent than prime numbers by nearly a logarithmic factor.
This bound gives the intuition that the sum of the reciprocals of the twin primes converges, or stated in other words, the twin primes form a small set. In explicit terms, the sum
either has finitely many terms or has infinitely many terms but is convergent: its value is known as Brun's constant.
If it were the case that the sum diverged, then that fact would imply that there are infinitely many twin primes. Because the sum of the reciprocals of the twin primes instead converges, it is not possible to conclude from this result that there are finitely many or infinitely many twin primes. Brun's constant could be an irrational number only if there are infinitely many twin primes.
Numerical estimates
The series converges extremely slowly. Thomas Nicely remarks

Biodiversity Information Standards (TDWG), originally called the Taxonomic Databases Working Group, is a non-profit scientific and educational association that works to develop open standards for the exchange of biodiversity data, facilitating biodiversity informatics. It is affiliated with the International Union of Biological Sciences. It is best known for the Darwin Core standard for exchanging biodiversity, which has been used by the Global Biodiversity Information Facility to collect millions of biological observations from museums and other organizations from around the world.
History
TDWG was founded in 1985 as the Taxonomic Databases Working Group; the first meeting took place on September 28–30, 1985, at the Conservatory and Botanical Garden of the City of Geneva in Switzerland. The organisation was formed as an international collaboration to promote the wider and more effective dissemination of information about biological organisms. Its name was changed to Taxonomic Databases Working Group for Plant Sciences in 1986. It was accepted as a commission of the International Union of Biological Sciences in October 1988. The name changed to International Working Group on Taxonomic Databases for Plant Sciences in 1988. Initially focusing on plant taxonomic databases, in 1994 it expanded its scope to cover all taxonomic databases and changed its name to International Working Group on Taxonomic Databases.
In 2006 the group decided to change their name to emphasise their fo

Sequent was a DikuMUD derivative codebase developed by Raja Kushalnagar ("Duke of Sequent"). It was a text-based online role-playing game that was an accessible DikuMUD based MUD. It added several new playing areas with shorter text descriptions that was designed to be accessible to users with sensory disabilities. It also supported more players online at the same time by being hosted on a Sequent multi-processor machine at the University of California, Berkeley, and was first started in March 1991.
History
The Sequent DikuMUD enhanced both the codebase and database of the DikuMUD Gamma version. The codebase enhancements increased the number of spells and guilds, plus supporting multiple active zones, chat channels and guilds. It added several new playing areas with shorter text descriptions that was designed to be accessible to users with sensory disabilities.
DikuMUD had been a great leveler and allowed people from diverse regions to connect and play together. People with sensory disabilities faced barriers in both social interaction and game playing in these games. DikuMUD were not accessible to people who could not see, but hear. Conversely, they were largely accessible to people who could see but not hear. The primary challenge was that there was too much information to scan through as they played the game. For instance, the average player had to type in commands to juggle regular checks of various properties such as movement, weapons and their range, status and cost,

Bobby Martin (November 3, 1987 – April 28, 2020) nicknamed "Bobby No Legs”, was born with Caudal regression syndrome. As he had no legs or hips, he used his arms to run. A graduate of Colonel White High School in Dayton, Ohio, he played defensive lineman for his high school varsity team. He later attended Central State University.
Biography
Martin was tall and weighed as he was born with a significant form of Caudal regression syndrome which resulted in being born without hips or legs. During his 2005 high school senior season, he was removed from play at half-time in a game against Mount Healthy High School by officials claiming he was in breach of league rules requiring players to wear thigh pads, knee pads and shoes. Colonel White High School was later told by the Ohio High School Athletic Association that this decision was incorrect and Martin was allowed to continue to finish the season. He finished the season with 48 tackles. At halftime of one game, he was named the Homecoming King. On July 12, 2006, Martin won the ESPY award for Best Male Athlete with a Disability.
After graduation, Martin studied marketing at Central State University and did not play football. In 2007, then Cleveland Browns head coach Romeo Crennel invited Martin to a practice. After seeing wide receiver Dennis Northcutt evade player after player, Martin approached Northcutt and claimed that he could tackle him. At the insistence of teammate Braylon Edwards, Northcutt allowed Martin to challenge

https://en.wikipedia.org/wiki/Asterids
|
In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade (a monophyletic group). Asterids is the largest group of flowering plants, with more than 80,000 species, about a third of the total flowering plant species. Well-known plants in this clade include the common daisy, forget-me-nots, nightshades (including potatoes, eggplants, tomatoes, chili peppers and tobacco), the common sunflower, petunias, yacon, morning glory, lettuce, sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, table herbs such as mint, basil, and rosemary, and rainforest trees such as Brazil nut.
Most of the taxa belonging to this clade had been referred to as Asteridae in the Cronquist system (1981) and as Sympetalae in earlier systems. The name asterids (not necessarily capitalised) resembles the earlier botanical name but is intended to be the name of a clade rather than a formal ranked name, in the sense of the ICBN.
History
Genetic analysis carried out after APG II maintains that the sister to all other asterids are the Cornales. A second order that split from the base of the asterids are the Ericales. The remaining orders cluster into two clades, the lamiids and the campanulids. The structure of both of these clades has changed in APG III.
In the APG III system, the following clades were renamed:
euasterids I → lamiids

Rowan and the Keeper of the Crystal is a 1996 children's fantasy novel by Australian author Emily Rodda. It is the third book in the Rowan of Rin series.
Plot summary
The Keeper of the Crystal – leader of the Maris people – is dying and a messenger brings this news to Rin Rowan of Rin learns that his mother, Jiller, is to choose the new leader from one of the three warring Maris clans. Doss of Pandellis, Asha of Umbray and Seaborn of Fisk are their names. When she falls victim to a strong poison, however, Rowan finds himself in the Chooser's position as well as trying to create the antidote to wake his mother from Death Sleep. Rowan then receives a riddle of how to make an antidote by bonding with the crystal and finding the recipe against the Keeper's will.
They then exit the cavern of the keeper to go to the island where Orin the first keeper went to make the antidote. They think that the water will be the answer to the second line, however Doss says that it is too obvious and that it would not be the sea water. Rowan then sights a slight glint in the trees and runs toward it. They discover that it is a pool of clear water. Seaborn is then asked to retrieve the water but once his hand touches the water, clear tubular leeches then get attached to his hand. He screams in pain and gives Rowan the water. Then a bird swoops down towards them, but is actually diving toward to the pool to grab some leeches. The pool then turns silver as the leeches bury themselves under the sil

https://en.wikipedia.org/wiki/Carboxymethyl%20cellulose
|
Carboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose. It used to be marketed under the name Tylose, a registered trademark of SE Tylose.
Preparation
Carboxymethyl cellulose is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. Fabrics made of cellulose—e.g. cotton or viscose rayon—may also be converted into CMC.
Following the initial reaction, the resultant mixture produces approximately 60% CMC and 40% salts (sodium chloride and sodium glycolate); this product is the so-called technical CMC, which is used in detergents. An additional purification process is used to remove salts to produce pure CMC, which is used for alimentary and pharmaceutical applications. An intermediate "semi-purified" grade is also produced, typically used in paper applications such as the restoration of archival documents.
Structure and properties
The functional properties of CMC depend on the degree of substitution of the cellulose structure [i.e., how many of the hydroxyl groups have been converted to carboxymethylene(oxy) groups in the substitution reaction], as well as the chain length of the cellulose backbone structure and the degree of cl

https://en.wikipedia.org/wiki/Blowout%20%28geomorphology%29
|
Blowouts are sandy depressions in a sand dune ecosystem (psammosere) caused by the removal of sediments by wind.
Commonly found in coastal settings and margins of arid areas, blowouts tend to form when wind erodes patches of bare sand on stabilized vegetated dunes. Generally, blowouts do not form on actively flowing dunes due to the fact that the dunes need to be bound to some extent, for instance by plant roots. These depressions usually start on the higher parts of stabilized dunes on account of the more considerable desiccation and disturbances occurring there, which allows for greater surface drag and sediment entrainment when the sand is bare. Most of the time, exposed areas become quickly re-vegetated before they can become blowouts and expand; however, when circumstances are favourable, wind erosion can gouge the exposed surface and create a tunneling effect which increases local wind speed. A depression may then develop until it hits a non-erodible substrate, or morphology limits it. The eroded substances climb the steep slopes of the depression and become deposited on the downwind side of the blowout which can form a dune that covers vegetation and lead to a larger depression; a process that helps create parabolic dunes.
Vegetation
Although there is a wide variety of vegetation that live in dune environments around the world, most plant species play a key role in determining whether blowouts will form or not by the result of how strong their protective skins can s

Jamestown is a town in the Mid North region of South Australia north of Adelaide. It lies on the banks of the Belalie Creek and on the Crystal Brook-Broken Hill railway line between Gladstone and Peterborough, and ultimately on the main line linking Adelaide and Perth to Sydney. Jamestown is the council seat of its local municipality, Northern Areas Council. Jamestown is in the South Australian Legislative Assembly electoral district of Stuart and the federal Division of Grey.
Description
Jamestown (originally James Town) was named after Sir James Fergusson, the Governor of South Australia when the town was surveyed in 1871. Its streets are all named for towns in his native Scotland.
Major products of the area are grain, legumes, wool and timber. The world's first plantation forest was the Bundaleer Forest first planted in the area in 1876. The local area had first been granted self-government as the District Council of Belalie in 1875, but the township of Jamestown itself had separated as the Corporate Town of Jamestown in 1878. The Belalie council, comprising the surrounding areas, merged into the new District Council of Jamestown in 1935. Jamestown continued with two municipalities, one for the town and one for the surrounding area, until their amalgamation in 1991; the amalgamated municipality then merged into the new Northern Areas Council in 1997.

Felix Platter (also Plater ; ; Latinized: Platerus; 28 October 1536 – 28 July 1614) was a Swiss physician, well known for his classification of psychiatric diseases, and was also the first to describe an intracranial tumour (a meningioma).
Biography
Felix Platter was the son of Lutheran humanist, schoolmaster and printer, Thomas Platter, and the half-brother of Thomas Platter the Younger. In 1552, and only fifteen years old, Platter travelled by pony from Basel to the University of Montpellier to start a course of study under Guillaume Rondelet. He earned his medical doctorate from Montpellier in 1557. Once arrived, he lodged in the house of Laurent Catalan, the town pharmacist and a Maran or Christian Jew. Platter occasionally sent packages of fruits and seeds to his father. His studies took place in an atmosphere of terror and religious persecution. Rondelet taught his students the technique of pressing, drying and mounting botanical specimens on paper, a process practised by his former mentor, Luca Ghini.
Returning to Basel in 1557, Platter soon established himself as a successful physician and became professor of practical medicine at the University of Basel, amassing a famous collection of curiosities at his house as well as an enormous library of pressed plant specimens.
Platter's description of Dupuytren's disease in 1614 is explained with regard to his understanding of the anatomy. The current view that Platter believed the disease to be caused by dislocation and s

In general relativity, a black brane is a solution of the equations that generalizes a black hole solution but it is also extended—and translationally symmetric—in p additional spatial dimensions. That type of solution would be called a black p-brane.
In string theory, the term black brane describes a group of D1-branes that are surrounded by a horizon. With the notion of a horizon in mind as well as identifying points as zero-branes, a generalization of a black hole is a black p-brane. However, many physicists tend to define a black brane separate from a black hole, making the distinction that the singularity of a black brane is not a point like a black hole, but instead a higher dimensional object.
A BPS black brane is similar to a BPS black hole. They both have electric charges. Some BPS black branes have magnetic charges.
The metric for a black p-brane in a n-dimensional spacetime is:
where:
η is the (p + 1)-Minkowski metric with signature (−, +, +, +, ...),
σ are the coordinates for the worldsheet of the black p-brane,
u is its four-velocity,
r is the radial coordinate and,
Ω is the metric for a (n − p − 2)-sphere, surrounding the brane.

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

Biuret is a chemical compound with the chemical formula . It is a white solid that is soluble in hot water. A variety of organic derivatives are known. The term "biuret" also describes a family of organic compounds with the chemical formula , where are hydrogen, organyl or other groups. Also known as carbamylurea, it results from the condensation of two equivalents of urea. It is a common undesirable impurity in urea-based fertilizers, as biuret is toxic to plants.
Preparation and structure
The parent compound can be prepared by heating urea at 150 °C for ~6 hours until it gets slightly cloudy, then recrystallizing from water. After that, it can be recrystallized repeatedly from 2% sodium hydroxide solution and water to finally get base-free crystalline needles of the monohydrate which are free of cyanuric acid. While heating, a lot of ammonia is expelled:
Under related conditions, pyrolysis of urea affords triuret .
In general, organic biurets (those with alkyl or aryl groups in place of one or more H atoms) are prepared by trimerization of isocyanates. For example, the trimer of 1,6-hexamethylene diisocyanate is also known as HDI-biuret.
In the anhydrous form, the molecule is planar and unsymmetrical in the solid state owing to intramolecular hydrogen bonding. The terminal C–N distances of 1.327 and 1.334 Å are shorter than the internal C–N distances of 1.379 and 1.391 Å. The C=O bond distances 1.247 and 1.237 Å. It crystallizes from water as the monohydrate.

KBOB is a radio station licensed to Davenport, Iowa, and airs a sports format. The station's frequency is 1170 kHz, and broadcasts at a power of 1 kW. Its transmitter is in Knoxville Road just outside of Milan, Illinois.
KBOB is owned by Townsquare Media, with studios located at 1229 Brady Street in Davenport, Iowa (along with the co-located KJOC, WXLP, KBEA-FM and KIIK-FM).
History
The station signed on July 7, 1946 as KSTT, broadcasting from the Hotel Davenport in downtown Davenport. Format was typical of the era, with big band and vocal pop, along with news, sports and farm markets.
It wasn't until the mid-1950s—when it began playing the then-new Top 40/Contemporary Hit Radio genre—that the station really took off in popularity. Disc jockeys made liberal use of listener requests and call-in contests. If there was a live broadcast or news happening in the Quad Cities, listeners were sure to spot the "Big Red" mobile news cruiser. KSTT also polled listeners on their favorite current songs, which disc jockeys then presented in a weekly countdown program. Quad Cities area servicemen in Vietnam had tapes of KSTT programming sent to them.
The station, which moved in 1963 to 1111 East River Drive in downtown Davenport, had a large window in its studio, where motorists could see their favorite on-air disc jockeys broadcasting. Listeners today remember such radio personalities as Jay Gregory, Mike Kenneally, Michelle Coleman, Tom Clay, Bill Young, Greg Garron, Bryan Bradford,

https://en.wikipedia.org/wiki/Arachnoid%20mater
|
The arachnoid mater (or simply arachnoid) is one of the three meninges, the protective membranes that cover the brain and spinal cord. It is so named because of its resemblance to a spider web. The arachnoid mater is a derivative of the neural crest mesoectoderm in the embryo.
Structure
The arachnoid mater is interposed between the two other meninges, the more superficial (closer to the surface) and much thicker dura mater and the deeper pia mater, from which it is separated by the subarachnoid space. The delicate arachnoid layer is not attached to the inside of the dura but against it and surrounds the brain and spinal cord. It does not line the brain down into its sulci (folds), as does the pia mater, with the exception of the longitudinal fissure, which divides the left and right cerebral hemispheres. Cerebrospinal fluid (CSF) flows under the arachnoid in the subarachnoid space, within a meshwork of trabeculae which span between the arachnoid and the pia. The arachnoid mater makes arachnoid villi, small protrusions through the dura mater into the venous sinuses of the brain, which allow CSF to exit the subarachnoid space and enter the blood stream.
Unlike the dura mater, which receives a rich vascular supply from numerous arteries, the arachnoid mater is avascular (lacking blood vessels).
The arachnoid mater and dura mater are very close together throughout the cranium and spinal canal all the way to S2, where the two layers fuse into one and end in the filum terminale

The phi X 174 (or ΦX174) bacteriophage is a single-stranded DNA (ssDNA) virus that infects Escherichia coli, and the first DNA-based genome to be sequenced. This work was completed by Fred Sanger and his team in 1977. In 1962, Walter Fiers and Robert Sinsheimer had already demonstrated the physical, covalently closed circularity of ΦX174 DNA. Nobel prize winner Arthur Kornberg used ΦX174 as a model to first prove that DNA synthesized in a test tube by purified enzymes could produce all the features of a natural virus, ushering in the age of synthetic biology. In 1972–1974, Jerard Hurwitz, Sue Wickner, and Reed Wickner with collaborators identified the genes required to produce the enzymes to catalyze conversion of the single stranded form of the virus to the double stranded replicative form. In 2003, it was reported by Craig Venter's group that the genome of ΦX174 was the first to be completely assembled in vitro from synthesized oligonucleotides. The ΦX174 virus particle has also been successfully assembled in vitro. In 2012, it was shown how its highly overlapping genome can be fully decompressed and still remain functional.
Genome
This bacteriophage has a [+] sense circular single-stranded DNA genome of 5,386 nucleotides. The genome GC-content is 44% and 95% of nucleotides belong to coding genes. Because of the balance base pattern of the genome, it is used as the control DNA for Illumina sequencers.

Blood meal can be used as a livestock dietary supplement and is mainly added to supply dietary lysine for cattle, fish and poultry. Prior to use, it is sometimes mixed with molasses.
Organic fertilizers
Blood meal, bone meal, and other animal by-products are permitted in certified organic production as soil amendments, though they cannot be fed to organic livestock. Blood meal is different from bone meal in that blood meal contains a higher amount of nitrogen, while bone meal contains phosphorus. Alternatives to Blood Meal include feather meal and alfalfa meal. Blood meal is sometimes used as a composting activator.
Pest control
Blood meal can be spread on gardens to deter pest animals such as rabbits. The theory is that the animals smell the blood and are repelled by the odor.
Classifications
It is a proteinaceous concentrate according to classifications of feed.
It is a protein-yielding feedstuff according to classifications of feedstuffs.
Processing
Blood needs to be dried before being used as blood meal. Several drying methods are available: solar drying, oven drying, drum drying, flash drying or spray drying.

https://en.wikipedia.org/wiki/Seemingly%20unrelated%20regressions
|
In econometrics, the seemingly unrelated regressions (SUR) or seemingly unrelated regression equations (SURE) model, proposed by Arnold Zellner in (1962), is a generalization of a linear regression model that consists of several regression equations, each having its own dependent variable and potentially different sets of exogenous explanatory variables. Each equation is a valid linear regression on its own and can be estimated separately, which is why the system is called seemingly unrelated, although some authors suggest that the term seemingly related would be more appropriate, since the error terms are assumed to be correlated across the equations.
The model can be estimated equation-by-equation using standard ordinary least squares (OLS). Such estimates are consistent, however generally not as efficient as the SUR method, which amounts to feasible generalized least squares with a specific form of the variance-covariance matrix. Two important cases when SUR is in fact equivalent to OLS are when the error terms are in fact uncorrelated between the equations (so that they are truly unrelated) and when each equation contains exactly the same set of regressors on the right-hand-side.
The SUR model can be viewed as either the simplification of the general linear model where certain coefficients in matrix are restricted to be equal to zero, or as the generalization of the general linear model where the regressors on the right-hand-side are allowed to be different in each e

|
The Motorola RAZR V3, popularly called simply the Razr (pronounced like "razor"), is a clamshell style cell phone developed by Motorola and initially released in November 2004, the first device using the RAZR moniker. With its unique and then-thin aluminium body, coupled with a high price, the RAZR V3 was initially positioned as a desirable premium phone; following price reductions, it then became extremely successful. In the United States the V3 (and its variants) was the most popular cell phone in 2005, 2006 and 2007 and remained best-selling until November 2008.
The Razr's design would strongly influence Motorola's later mobile phone products, and the V3 itself received several updates to form the RAZR line: the V3i, V3x, V3xx and MAXX. The Razr series was succeeded in July 2007 by the Motorola Razr2 series.
Development and design
Codenamed Siliqua, the original RAZR series of flip phones was part of the 4LTR line. Development of the V3 started in July 2003 with Motorola aiming to create a very skinny phone. It was announced on July 27, 2004 and released in the market in late 2004.
The team of the V3 put together a number of design choices that set the device apart from the competition. The phone had the thinnest profile at the time on a clamshell set, sported an electroluminescent keypad made out of a single metal wafer and used an industry-standard mini-USB port for data, battery charger and headphones, housed in an aluminum body with an external glass screen.

https://en.wikipedia.org/wiki/Classification%20of%20inhabited%20localities%20in%20Russia
|
The classification system of inhabited localities in Russia and some other post-Soviet states has certain peculiarities compared with those in other countries.
Classes
During the Soviet time, each of the republics of the Soviet Union, including the Russian SFSR, had its own legislative documents dealing with classification of inhabited localities. After the dissolution of the Soviet Union, the task of developing and maintaining such classification in Russia was delegated to the federal subjects. While currently there are certain peculiarities to classifications used in many federal subjects, they are all still largely based on the system used in the RSFSR. In all federal subjects, the inhabited localities are classified into two major categories: urban and rural. Further divisions of these categories vary slightly from one federal subject to another, but they all follow common trends described below.
Urban
Cities and towns (, gorod; pl. , goroda). Cities and towns are classified by their level of jurisdiction (district/federal subject/federal). The Russian language has no separate words for "town" and "city" ("" is used for both). Some translators prefer the word "city" for urban populated places with population of at least 100,000 persons.
Urban-type settlements (, posyolok gorodskogo tipa; pl. ) is a type of smaller urban locality. This type of urban locality was first introduced in the Soviet Union in 1924, with the following subcategories:

https://en.wikipedia.org/wiki/Mid-range
|
In statistics, the mid-range or mid-extreme is a measure of central tendency of a sample defined as the arithmetic mean of the maximum and minimum values of the data set:
The mid-range is closely related to the range, a measure of statistical dispersion defined as the difference between maximum and minimum values.
The two measures are complementary in sense that if one knows the mid-range and the range, one can find the sample maximum and minimum values.
The mid-range is rarely used in practical statistical analysis, as it lacks efficiency as an estimator for most distributions of interest, because it ignores all intermediate points, and lacks robustness, as outliers change it significantly. Indeed, for many distributions it is one of the least efficient and least robust statistics. However, it finds some use in special cases: it is the maximally efficient estimator for the center of a uniform distribution, trimmed mid-ranges address robustness, and as an L-estimator, it is simple to understand and compute.
Robustness
The midrange is highly sensitive to outliers and ignores all but two data points. It is therefore a very non-robust statistic, having a breakdown point of 0, meaning that a single observation can change it arbitrarily. Further, it is highly influenced by outliers: increasing the sample maximum or decreasing the sample minimum by x changes the mid-range by while it changes the sample mean, which also has breakdown point of 0, by only It is thus of little

https://en.wikipedia.org/wiki/Computational%20model
|
A computational model uses computer programs to simulate and study complex systems using an algorithmic or mechanistic approach and is widely used in a diverse range of fields spanning from physics, engineering, chemistry and biology to economics, psychology, cognitive science and computer science.
The system under study is often a complex nonlinear system for which simple, intuitive analytical solutions are not readily available. Rather than deriving a mathematical analytical solution to the problem, experimentation with the model is done by adjusting the parameters of the system in the computer, and studying the differences in the outcome of the experiments. Operation theories of the model can be derived/deduced from these computational experiments.
Examples of common computational models are weather forecasting models, earth simulator models, flight simulator models, molecular protein folding models, Computational Engineering Models (CEM), and neural network models.

https://en.wikipedia.org/wiki/Gap%20theorem
|
See also Gap theorem (disambiguation) for other gap theorems in mathematics.
In computational complexity theory, the Gap Theorem, also known as the Borodin–Trakhtenbrot Gap Theorem, is a major theorem about the complexity of computable functions.
It essentially states that there are arbitrarily large computable gaps in the hierarchy of complexity classes. For any computable function that represents an increase in computational resources, one can find a resource bound such that the set of functions computable within the expanded resource bound is the same as the set computable within the original bound.
The theorem was proved independently by Boris Trakhtenbrot and Allan Borodin.
Although Trakhtenbrot's derivation preceded Borodin's by several years, it was not known nor recognized in the West until after Borodin's work was published.
Gap theorem
The general form of the theorem is as follows.
Suppose is an abstract (Blum) complexity measure. For any total computable function for which for every , there is a total computable function such that with respect to , the complexity classes with boundary functions and are identical.
The theorem can be proved by using the Blum axioms without any reference to a concrete computational model, so it applies to time, space, or any other reasonable complexity measure.
For the special case of time complexity, this can be stated more simply as:
for any total computable function such that for all , there exists a time bound su

Boris (Boaz) Abramovich Trakhtenbrot (, ; 19 February 1921 – 19 September 2016) was a Russian-Israeli mathematician in logic, algorithms, theory of computation, and cybernetics.
Biography
Trakhtenbrot was born into a Jewish family in Brichevo, northern Bessarabia (now Tîrnova, Moldova). He studied at the Moldovan State Pedagogical Institute in Kishinev, Chernivtsi University, and the Ukrainian Academy of Science's Mathematical Institute, completing a Ph.D. at the latter institution in 1950.
He worked at Akademgorodok, Novosibirsk during the 1960s and 1970s. In 1964 Trakhtenbrot discovered and proved a fundamental result in theoretical computer science called the gap theorem. He also discovered and proved the theorem in logic, model theory, and computability theory now known as Trakhtenbrot's theorem.
After immigrating to Israel in 1981, he became a professor in the Faculty of Exact Sciences at Tel Aviv University, and continued as professor emeritus until his death. He died on 19 September 2016, at the age of 95.

https://en.wikipedia.org/wiki/Image%20tracing
|
In computer graphics, image tracing, raster-to-vector conversion or raster vectorization is the conversion of raster graphics into vector graphics.
Background
An image does not have any structure: it is just a collection of marks on paper, grains in film, or pixels in a bitmap. While such an image is useful, it has some limits. If the image is magnified enough, its artifacts appear. The halftone dots, film grains, and pixels become apparent. Images of sharp edges become fuzzy or jagged. See, for example, pixelation. Ideally, a vector image does not have the same problem. Edges and filled areas are represented as mathematical curves or gradients, and they can be magnified arbitrarily (though of course the final image must also be rasterized in to be rendered, and its quality depends on the quality of the rasterization algorithm for the given inputs).
The task in vectorization is to convert a two-dimensional image into a two-dimensional vector representation of the image. It is not examining the image and attempting to recognize or extract a three-dimensional model which may be depicted; i.e. it is not a vision system. For most applications, vectorization also does not involve optical character recognition; characters are treated as lines, curves, or filled objects without attaching any significance to them. In vectorization, the shape of the character is preserved, so artistic embellishments remain.
Vectorization is the inverse operation corresponding to rasterization, as

https://en.wikipedia.org/wiki/Agrophysics
|
Agrophysics is a branch of science bordering on agronomy and physics,
whose objects of study are the agroecosystem - the biological objects, biotope and biocoenosis affected by human activity, studied and described using the methods of physical sciences. Using the achievements of the exact sciences to solve major problems in agriculture, agrophysics involves the study of materials and processes occurring in the production and processing of agricultural crops, with particular emphasis on the condition of the environment and the quality of farming materials and food production.
Agrophysics is closely related to biophysics, but is restricted to the physics of the plants, animals, soil and an atmosphere involved in agricultural activities and biodiversity. It is different from biophysics in having the necessity of taking into account the specific features of biotope and biocoenosis, which involves the knowledge of nutritional science and agroecology, agricultural technology, biotechnology, genetics etc.
The needs of agriculture, concerning the past experience study of the local complex soil and next plant-atmosphere systems, lay at the root of the emergence of a new branch – agrophysics – dealing this with experimental physics.
The scope of the branch starting from soil science (physics) and originally limited to the study of relations within the soil environment, expanded over time onto influencing the properties of agricultural crops and produce as foods and raw postharvest

https://en.wikipedia.org/wiki/Lazarus%20Fuchs

Lazarus Immanuel Fuchs (5 May 1833 – 26 April 1902) was a Jewish-German mathematician who contributed important research in the field of linear differential equations. He was born in Moschin (Mosina) (located in Grand Duchy of Posen) and died in Berlin, Germany. He was buried in Schöneberg in the St. Matthew's Cemetery. His grave in section H is preserved and listed as a grave of honour of the State of Berlin.
He is the eponym of Fuchsian groups and functions, and the Picard–Fuchs equation.
A singular point a of a linear differential equation
is called Fuchsian if p and q are meromorphic around the point a,
and have poles of orders at most 1 and 2, respectively.
According to a theorem of Fuchs, this condition is necessary and sufficient
for the regularity of the singular point, that is, to ensure the existence
of two linearly independent solutions of the form
where the exponents can be determined from the equation. In the case when
is an integer this formula has to be modified.
Another well-known result of Fuchs is the Fuchs's conditions, the necessary and sufficient conditions
for the non-linear differential equation of the form
to be free of movable singularities.
An interest remark about him as a teacher during the period of his work at the Heidelberg University pertains to his manner of lecturing: his knowledge of the mathematics he was assigned to teach was so deep that he was wont not to prepare before giving a lecture — he would simply improvise on the spot,

https://en.wikipedia.org/wiki/Glucose%20transporter
|
Glucose transporters are a wide group of membrane proteins that facilitate the transport of glucose across the plasma membrane, a process known as facilitated diffusion. Because glucose is a vital source of energy for all life, these transporters are present in all phyla. The GLUT or SLC2A family are a protein family that is found in most mammalian cells. 14 GLUTS are encoded by the human genome. GLUT is a type of uniporter transporter protein.
Synthesis of free glucose
Most non-autotrophic cells are unable to produce free glucose because they lack expression of glucose-6-phosphatase and, thus, are involved only in glucose uptake and catabolism. Usually produced only in hepatocytes, in fasting conditions, other tissues such as the intestines, muscles, brain, and kidneys are able to produce glucose following activation of gluconeogenesis.
Glucose transport in yeast
In Saccharomyces cerevisiae glucose transport takes place through facilitated diffusion. The transport proteins are mainly from the Hxt family, but many other transporters have been identified.
Glucose transport in mammals
GLUTs are integral membrane proteins that contain 12 membrane-spanning helices with both the amino and carboxyl termini exposed on the cytoplasmic side of the plasma membrane. GLUT proteins transport glucose and related hexoses according to a model of alternate conformation, which predicts that the transporter exposes a single substrate binding site toward either the outside or the inside of t

https://en.wikipedia.org/wiki/Destination-Sequenced%20Distance%20Vector%20routing
|
Destination-Sequenced Distance-Vector Routing (DSDV) is a table-driven routing scheme for ad hoc mobile networks based on the Bellman–Ford algorithm. It was developed by C. Perkins and P. Bhagwat in 1994. The main contribution of the algorithm was to solve the routing loop problem. Each entry in the routing table contains a sequence number, the sequence numbers are generally even if a link is present; else, an odd number is used. The number is generated by the destination, and the emitter needs to send out the next update with this number. Routing information is distributed between nodes by sending full dumps infrequently and smaller incremental updates more frequently.
For example, the routing table of Node A in this network is
Naturally the table contains description of all possible paths reachable by node A, along with the next hop, number of hops and sequence number.
Selection of Route
If a router receives new information, then it uses the latest sequence number. If the sequence number is the same as the one already in the table, the route with the better metric is used. Stale entries are those entries that have not been updated for a while. Such entries as well as the routes using those nodes as next hops are deleted.
Advantages
The availability of paths to all destinations in network always shows that less delay is required in the path set up process.
The method of incremental update with sequence number labels, marks the existing wired network protocols adapta
