https://en.wikipedia.org/wiki/Blaze%20%28UAB%20mascot%29
|
Blaze is the mascot of the University of Alabama at Birmingham's athletics teams. He is a fire-breathing European dragon.
UAB's athletic history goes back to 1977, when Gene Bartow was named the school's first athletic director. In January 1978, a campuswide vote bestowed the nickname "Blazers" on the team, hoping that the teams would "blaze" a new trail in college athletics. Originally, there was no official mascot, but that changed in 1995, when a European dragon was chosen as the mascot.
On January 6, 1996, "Blaze" was introduced at a basketball game. "Blaze" is considered a member of the spirit squads, and appears at all football and basketball games. Blaze's head has appeared on the sides of UAB's football helmets since 1996, when the team moved up to Division I-A.

https://en.wikipedia.org/wiki/Oscillistor
|
An oscillistor is a semiconductor device, consisting of a semiconductor specimen placed in magnetic field, and a resistor after a power supply. The device produces high-frequency oscillations, which are very close to sinusoidal.
The basic principle of operation is the effect of spiral unsteadiness of electron-hole (p-n) plasmas.

The Georgia Innocence Project is a non-profit corporation based in Atlanta, Georgia, United States. Its mission "is to free the wrongly prosecuted through DNA testing, to advance practices that minimize the chances that others suffer the same fate, to educate the public that wrongful convictions are not rare or isolated events, and to help the exonerated rebuild their lives."
It was founded in August 2002 by September Guy and Jill Polster, and was headed by Executive Director Aimee Maxwell. Georgia Innocence Project is now headed by Executive Director Clare Gilbert. Cases that are accepted are assigned to a team of a volunteer lawyer and two interns. Thirteen people have been exonerated by the organization's efforts, the first two being Clarence Harrison in August 2004, and Robert Clark in December 2005.
On January 22, 2007, a third Georgia Innocence Project client, Pete Williams, was freed after spending 21 years in prison. In 1985, a jury convicted Williams for the rape of a Sandy Springs woman. Williams was exonerated based upon DNA evidence. The organization's fourth successful case is that of John White, now 48, who was released from Macon State Prison on December 10, 2007, after twenty-eight years in prison. Through the efforts of the Georgia Innocence Project, the Georgia Bureau of Investigation (GBI) performed DNA testing that proves White is innocent of the August 1979 rape, aggravated assault, burglary and robbery for an attack on an elderly woman in Meriwether Co

https://en.wikipedia.org/wiki/Prolamin
|
Prolamins are a group of plant storage proteins having a high proline amino acid content. They are found in plants, mainly in the seeds of cereal grains such as wheat (gliadin), barley (hordein), rye (secalin), corn (zein), sorghum (kafirin), and oats (avenin). They are characterised by a high glutamine and proline content, and have poor solubility in water. They solubilise best in strong alcohol [70-80%], light acid, and alkaline solutions. The prolamins of the tribe Triticeae, such as wheat gliadin, and related proteins (see Triticeae glutens) are known to trigger coeliac disease, an autoimmune condition, in genetically predisposed individuals.
Maize and sorghum prolamins are sorted by molecular weight into four classes, α, β, γ and δ. Alpha- and delta- prolamins cluster in a broad phylogenetic group (Group 1). The rest cluster into Group 2. Group 1 is widely duplicated in the two plants. A database of Triticeae prolamins (glutens) is available. There does not seem to be an analysis that tries to cluster both sources of prolamins into a grand classification.

https://en.wikipedia.org/wiki/Aspartate%20kinase
|
Aspartate kinase or aspartokinase (AK) is an enzyme that catalyzes the phosphorylation of the amino acid aspartate. This reaction is the first step in the biosynthesis of three other amino acids: methionine, lysine, and threonine, known as the "aspartate family". Aspartokinases are present only in microorganisms and plants, but not in animals, which must obtain aspartate-family amino acids from their diet. Consequently, methionine, lysine and threonine are essential amino acids in animals.
Nomenclature
The generic abbreviation for aspartokinases is AK. However, the nomenclature for aspartokinase genes and proteins varies considerable among species. The main aspatokinases are lysC (Bacillus subtilis, Escherichia coli and many other bacteria), ask (Mycobacterium bovis, Thermus thermophilus), AK1–AK3 (Arabidopsis thaliana), FUB3 (Fusarium and Gibberella) and HOM3 (Saccharomyces cerevisiae). Additionally, apk is a synonym for lysC.
Enzymatic regulation
Aspartokinases may use the morpheein model of allosteric regulation.
In Escherichia coli, aspartokinase is present as three independently regulated isozymes (thrA, metLM and lysC), each of which is specific to one of the three downstream biochemical pathways. This allows the independent regulation of the rates of methionine, lysine, and threonine production. The forms that produce threonine and lysine are subject to feedback inhibition, and all three can be repressed at the level of gene expression by high concentrations of thei

https://en.wikipedia.org/wiki/5-polytope
|
In geometry, a five-dimensional polytope (or 5-polytope) is a polytope in five-dimensional space, bounded by (4-polytope) facets, pairs of which share a polyhedral cell.
Definition
A 5-polytope is a closed five-dimensional figure with vertices, edges, faces, and cells, and 4-faces. A vertex is a point where five or more edges meet. An edge is a line segment where four or more faces meet, and a face is a polygon where three or more cells meet. A cell is a polyhedron, and a 4-face is a 4-polytope. Furthermore, the following requirements must be met:
Each cell must join exactly two 4-faces.
Adjacent 4-faces are not in the same four-dimensional hyperplane.
The figure is not a compound of other figures which meet the requirements.
Characteristics
The topology of any given 5-polytope is defined by its Betti numbers and torsion coefficients.
The value of the Euler characteristic used to characterise polyhedra does not generalize usefully to higher dimensions, whatever their underlying topology. This inadequacy of the Euler characteristic to reliably distinguish between different topologies in higher dimensions led to the discovery of the more sophisticated Betti numbers.
Similarly, the notion of orientability of a polyhedron is insufficient to characterise the surface twistings of toroidal polytopes, and this led to the use of torsion coefficients.
Classification
5-polytopes may be classified based on properties like "convexity" and "symmetry".
A 5-polytope is convex if i

https://en.wikipedia.org/wiki/Somnoplasty
|
Somnoplasty is a trademark by Somnus Medical Technologies used for its radiofrequency ablation medical devices cleared by the Food and Drug Administration (FDA) to treat habitual snoring, chronic nasal obstruction, and obstructive sleep apnea (OSA) to shrink the tissues that are causing obstruction. Somnoplasty is typically an outpatient procedure that takes 30–45 minutes.
Procedure
Prior to somnoplasty procedure, a doctor may want a patient to attempt more conservative remedies such as sleeping in a different position. Once the Somnoplasty procedure is started, the patient is given a local anesthetic and a special needle-like electrode with an insulating sleeve covering all but the tip, that delivers RF energy under the surface of the tissue. The electrode is used to administer controlled, low-power RF energy to create coagulative (clotting) lesions, where tissue is denatured, beneath the mucosa (lining) of the targeted areas:
For chronic nasal obstruction, the turbinates are targeted
For habitual snoring, the soft palate and the uvula are targeted
For obstructive sleep apnea, the base of the tongue and other airway structures are targeted
Note: the actual areas targeted depends on each individual's specific anatomy, so the above are just general associations.
After 6–8 weeks, the lesions are naturally resorbed as the necrotic tissue is swept away and the surface sinks to fill the void, which reduces the volume of the tissue while stiffening what remains. When this oc

https://en.wikipedia.org/wiki/Knee%20effusion
|
Knee effusion, informally known as water on the knee, occurs when excess synovial fluid accumulates in or around the knee joint. It has many common causes, including arthritis, injury to the ligaments or meniscus, or fluid collecting in the bursa, a condition known as prepatellar bursitis.
Signs and symptoms
Signs and symptoms of water on the knee depend on the cause of excess synovial fluid build-up in the knee joint. These may include:
Pain
Osteoarthritis knee pain usually occurs while the joint is bearing weight, so the pain typically subsides with rest; some patients experience severe pain, while others report no discomfort. Even if one knee is much larger than the other, pain is not guaranteed.
Swelling
One knee may appear larger than the other. Puffiness around the bony parts of the knee appear prominent when compared with the other knee.
Stiffness
When the knee joint contains excess fluid, it may become difficult or painful to bend or straighten. Fluid may also show under the knee when straightened. Icing may help to decrease swelling. Heat may help relax the muscles of the knee.
Bruising
If an individual has injured their knee, they may note bruising on the front, sides or rear of the knee. Bearing weight on the knee joint may be impossible and the pain unbearable. Bruising may be seen as bluish lesion.
Causes
Causes of the swelling can include arthritis, injury to the ligaments of the knee, or an accident after which the body's natural reaction is to surround t

CUTEr (Constrained and Unconstrained Testing Environment, revisited) is an open source testing environment for optimization and linear algebra solvers. CUTEr provides a collection of test problems along with a set of tools to help developers design, compare, and improve new and existing test problem solvers.
CUTEr is the successor of the original Constrained and Unconstrained Testing Environment (CUTE) of Bongartz, Conn, Gould and Toint. It provides support for a larger number of platforms and operating systems as well as a more convenient optimization toolbox.
The test problems provided in CUTEr are written in Standard Input Format (SIF). A decoder to convert from this format into well-defined subroutines and data files is available as a separate package. Once translated, these files may be manipulated to provide tools suitable for testing optimization packages. Ready-to-use interfaces to existing packages, such as IPOPT, MINOS, SNOPT, filterSQP, Knitro and more are provided. The problems in the CUTE subset are also available in the AMPL format.
More than 1000 problems are available in the collection, including problems in:
linear programming,
convex and nonconvex quadratic programming,
linear and nonlinear least squares, and
more general convex and nonconvex large-scale and sparse equality and inequality-constrained nonlinear programming.
Over time, the CUTEr test set has become the de facto standard benchmark for research and production-level optimization solvers, and

https://en.wikipedia.org/wiki/Azoospermia%20factor
|
Azoospermia factor (AZF) is one of several proteins or their genes, which are coded from the AZF region on the human male Y chromosome. Deletions in this region are associated with inability to produce sperm. Subregions within the AZF region are AZFa (sometimes AZF1), AZFb and AZFc (together referred to as AZF2). AZF microdeletions are one of the major causes of male infertility for azoospermia (complete absence of sperm in the ejaculate) and severe oligozoospermia (less than 5 million spermatozoa in the ejaculate) males. AZF is the term used by the HUGO Gene Nomenclature Committee.
Of the 15% of couples who are affected by infertility, 50% of those cases are due to the male partner. 15-30% of male factor infertility cases can be correlated with genetic abnormalities. One of the most commonly identified genetic abnormalities in male factor infertility are microdeletions on the long arm of the Y chromosome (Yq), specifically at a region known as the azoospermic factor (AZF) region.
In certain circumstances, men with AZF mutations can turn to assisted reproductive technologies (ART), such as intracytoplasmic sperm injection (ICSI), to help them overcome their suboptimal sperm quality. However, it may be more important for clinicians to screen for Yq microdeletions, due to a growing body of evidence that AZF microdeletions have the capability to be vertically transmitted to male offspring. Minor et al. demonstrated that an AZFc mutation was vertically transmitted over three ge

https://en.wikipedia.org/wiki/Wiener%E2%80%93Ikehara%20theorem
|
The Wiener–Ikehara theorem is a Tauberian theorem introduced by . It follows from Wiener's Tauberian theorem, and can be used to prove the prime number theorem (Chandrasekharan, 1969).
Statement
Let A(x) be a non-negative, monotonic nondecreasing function of x, defined for 0 ≤ x < ∞. Suppose that
converges for ℜ(s) > 1 to the function ƒ(s) and that, for some non-negative number c,
has an extension as a continuous function for ℜ(s) ≥ 1.
Then the limit as x goes to infinity of e−x A(x) is equal to c.
One Particular Application
An important number-theoretic application of the theorem is to Dirichlet series of the form
where a(n) is non-negative. If the series converges to an analytic function in
with a simple pole of residue c at s = b, then
Applying this to the logarithmic derivative of the Riemann zeta function, where the coefficients in the Dirichlet series are values of the von Mangoldt function, it is possible to deduce the Prime number theorem from the fact that the zeta function has no zeroes on the line

https://en.wikipedia.org/wiki/Familial%20hypercholesterolemia
|
Familial hypercholesterolemia (FH) is a genetic disorder characterized by high cholesterol levels, specifically very high levels of low-density lipoprotein cholesterol (LDL cholesterol), in the blood and early cardiovascular diseases. The most common mutations diminish the number of functional LDL receptors in the liver or produce abnormal LDL receptors that never go to the cell surface to function properly (abnormal trafficking). Since the underlying body biochemistry is slightly different in individuals with FH, their high cholesterol levels are less responsive to the kinds of cholesterol control methods which are usually more effective in people without FH (such as dietary modification and statin tablets). Nevertheless, treatment (including higher statin doses) is usually effective.
FH is classified as a type 2 familial dyslipidemia. There are five types of familial dyslipidemia (not including subtypes), and each are classified from both the altered lipid profile and by the genetic abnormality. For example, high LDL (often due to LDL receptor defect) is type 2. Others include defects in chylomicron metabolism, triglyceride metabolism, and metabolism of other cholesterol-containing particles, such as VLDL and IDL.
About 1 in 100 to 200 people have mutations in the LDLR gene that encodes the LDL receptor protein, which normally removes LDL from the circulation, or apolipoprotein B (ApoB), which is the part of LDL that binds with the receptor; mutations in other genes are r

Frank M. Bass (December 27, 1926 – December 1, 2006) was an American academic in the field of marketing research and marketing science. He was the creator of the Bass diffusion model that describes the adoption of new products and technologies by first-time buyers. He died on December 1, 2006.
Career
Bass grew up in the small town of Cuero, Texas. He served in the United States Navy for two years (1944–46).
He received his BBA from Southwestern University in 1949, and his MBA from the University of Texas in 1950. After completing his M.B.A. at Texas, he became interested in marketing issues. He worked as a teaching assistant and assistant professor in marketing while earning his Ph.D. at the University of Illinois in 1954. In 1957 he became an assistant professor in marketing at the University of Texas.
In 1959, Bass was made a Fellow at Harvard University's Institute of Basic Mathematics For Application to Business. This exposure to advanced analytic methods influenced his research for the next 47 years. In 1961 he became a professor of industrial administration at the Graduate School of Purdue University. In 1969 he published the paper on modeling consumer goods, which later became known as the Bass diffusion model. The model describes the process of how new products and services are adopted as the outcome of an interaction between users and potential users. The Bass Model is a well-known empirical generalization in marketing, along with the Dirichlet (Ehrenberg et al.

https://en.wikipedia.org/wiki/Bass%20diffusion%20model
|
The Bass model or Bass diffusion model was developed by Frank Bass. It consists of a simple differential equation that describes the process of how new products get adopted in a population. The model presents a rationale of how current adopters and potential adopters of a new product interact. The basic premise of the model is that adopters can be classified as innovators or as imitators, and the speed and timing of adoption depends on their degree of innovation and the degree of imitation among adopters. The Bass model has been widely used in forecasting, especially new products' sales forecasting and technology forecasting. Mathematically, the basic Bass diffusion is a Riccati equation with constant coefficients equivalent to Verhulst—Pearl Logistic growth.
In 1969, Frank Bass published his paper on a new product growth model for consumer durables. Prior to this, Everett Rogers published Diffusion of Innovations, a highly influential work that described the different stages of product adoption. Bass contributed some mathematical ideas to the concept. While the Rogers model describes all four stages of the product lifecycle (Introduction, Growth, Maturity, Decline), The Bass model focuses on the first two (Introduction and Growth). Some of the Bass-Model extensions present mathematical models for the last two (Maturity and Decline).

https://en.wikipedia.org/wiki/Orotidine%205%27-phosphate%20decarboxylase
|
Orotidine 5'-phosphate decarboxylase (OMP decarboxylase) or orotidylate decarboxylase is an enzyme involved in pyrimidine biosynthesis. It catalyzes the decarboxylation of orotidine monophosphate (OMP) to form uridine monophosphate (UMP). The function of this enzyme is essential to the de novo biosynthesis of the pyrimidine nucleotides uridine triphosphate, cytidine triphosphate, and thymidine triphosphate. OMP decarboxylase has been a frequent target for scientific investigation because of its demonstrated extreme catalytic efficiency and its usefulness as a selection marker for yeast strain engineering.
Catalysis
OMP decarboxylase is known for being an extraordinarily efficient catalyst capable of accelerating the uncatalyzed reaction rate by a factor of 1017. To put this in perspective, the uncatalysed reaction which would take 78 million years to convert half the reactants into products is accelerated to 18 milliseconds when catalyzed by OMP decarboxylase. This extreme enzymatic efficiency is especially interesting because OMP decarboxylases uses no cofactor and contains no metal sites or prosthetic groups. The catalysis relies on a handful of charged amino acid residues positioned within the active site of the enzyme.
The exact mechanism by which OMP decarboxylase catalyzes its reaction has been a subject of rigorous scientific investigation. The driving force for the loss of the carboxyl linked to the C6 of the pyrimidine ring comes from the close proximity of

In mathematics, the metric derivative is a notion of derivative appropriate to parametrized paths in metric spaces. It generalizes the notion of "speed" or "absolute velocity" to spaces which have a notion of distance (i.e. metric spaces) but not direction (such as vector spaces).
Definition
Let be a metric space. Let have a limit point at . Let be a path. Then the metric derivative of at , denoted , is defined by
if this limit exists.
Properties
Recall that ACp(I; X) is the space of curves γ : I → X such that
for some m in the Lp space Lp(I; R). For γ ∈ ACp(I; X), the metric derivative of γ exists for Lebesgue-almost all times in I, and the metric derivative is the smallest m ∈ Lp(I; R) such that the above inequality holds.
If Euclidean space is equipped with its usual Euclidean norm , and is the usual Fréchet derivative with respect to time, then

https://en.wikipedia.org/wiki/UVB-76
|
UVB-76 (; see other callsigns), also known by the nickname "The Buzzer", is a shortwave radio station that broadcasts on the frequency of 4625 kHz. It broadcasts a short, monotonous , repeating at a rate of approximately 25 tones per minute, 24 hours per day. Sometimes, the buzzer signal is interrupted and a voice transmission in Russian takes place.
Name and callsigns
The station is commonly known as "The Buzzer" in both English and Russian (). From its first voice transmission in 1997 to 2010, the station identified itself as UZB-76 (). The callsign UVB-76 was never used by the station itself, but is rather a mistranscription of UZB-76. However, the station is still often referred to by that name. In the following years of transmission, the main callsign of the station changed regularly.
In addition to these main callsigns, The Buzzer also uses other "side callsigns" which are being used less frequently than the main callsign. Whenever the main callsign changes, all previous side callsigns are also discarded.
Format
The station transmits using AM with a suppressed lower sideband (USB modulation), but it has also used full double-sideband AM (A3E). The signal consists of a buzzing sound that lasts 1.2 seconds, pausing for 1–1.3 seconds, and repeating 21–34 times per minute. Until November 2010, the buzz tones lasted approximately 0.8 seconds each. One minute before the hour, the repeating tone was previously replaced by a continuous, uninterrupted alternating tone, which

https://en.wikipedia.org/wiki/Crystal%20Heights
|
Crystal Heights (also referred to as Crystal City) was a design by American architect Frank Lloyd Wright for a hotel, apartment, and shopping complex in Washington, D.C. The project would have been built on one of the largest remaining undeveloped tracts in the city, known as the Oak Lawn estate or Temple Heights, on the edge of the Adams Morgan and Dupont Circle neighborhoods. The site was bounded by 19th Street, Columbia Road, Connecticut Avenue, and Florida Avenue, all in the northwest quadrant.
One version of the design called for 2,500 hotel rooms, small apartments, parking for 1,500 cars, shops, and a 1,000-seat theater – a diversity of uses almost never seen in structures of the time – all within a complex consisting of a broad base covering the whole site topped by 15 towers. The proposal was defeated primarily by zoning requirements that prevented a multi-purpose structure at the site and forbade towers from rising more than 110 feet. The planned central tower would have been high and the remaining buildings 14-stories tall. After his design was rejected, Wright heavily criticized local officials and the National Capital Planning Commission. Today, the site is occupied by the Washington Hilton, commercial buildings, and an apartment building.

https://en.wikipedia.org/wiki/Galahad%20library
|
The Galahad library is a thread-safe library of packages for the solution of mathematical optimization problems. The areas covered by the library are unconstrained and bound-constrained optimization, quadratic programming, nonlinear programming, systems of nonlinear equations and inequalities, and non-linear least squares problems. The library is mostly written in the Fortran 90 programming language.
The name of the library originates from its major package for general nonlinear programming, LANCELOT-B, the successor of the original augmented Lagrangian package LANCELOT of Conn, Gould and Toint.
Other packages in the library include:
a filter-based method for systems of linear and nonlinear equations and inequalities,
an active-set method for nonconvex quadratic programming,
a primal-dual interior-point method for nonconvex quadratic programming,
a presolver for quadratic programs,
a Lanczos method for trust-region subproblems,
an interior-point method to solve linear programs or separable convex programs or alternatively, to compute the analytic center of a set defined by such constraints, if it exists.
Packages in the GALAHAD library accept problems modeled in either the Standard Input Format (SIF), or the AMPL modeling language. For problems modeled in the SIF, the GALAHAD library naturally relies upon the CUTEr package, an optimization toolbox providing all low-level functionalities required by solvers.
The library is available on several popular computing platf

In statistics and information theory, the expected formation matrix of a likelihood function is the matrix inverse of the Fisher information matrix of , while the observed formation matrix of is the inverse of the observed information matrix of .
Currently, no notation for dealing with formation matrices is widely used, but in books and articles by Ole E. Barndorff-Nielsen and Peter McCullagh, the symbol is used to denote the element of the i-th line and j-th column of the observed formation matrix. The geometric interpretation of the Fisher information matrix (metric) leads to a notation of following the notation of the (contravariant) metric tensor in differential geometry. The Fisher information metric is denoted by so that using Einstein notation we have .
These matrices appear naturally in the asymptotic expansion of the distribution of many statistics related to the likelihood ratio.

https://en.wikipedia.org/wiki/Showoffs
|
Showoffs is an American television game show which ran on ABC from June 30 to December 26, 1975. Bobby Van was host, with Gene Wood as announcer. The Mark Goodson-Bill Todman production involved two teams competing in a game of charades.
Gameplay
Two teams of three players competed. The teams were composed of two celebrity guests and one civilian contestant. One team wore red sweaters and the other blue over their street clothes.
Because the team colors were indistinguishable on monochrome-only television sets (which were still somewhat common in 1975), the words "REDS" and "BLUES" were later printed on the front of each team member's sweater for the benefit of home viewers.
Format #1
One team was isolated while two members of the other team acted out a series of words to their partner for sixty seconds. The actors could alternate in acting, and the guessing partner could pass on a word if he or she got stuck, but he or she could do that only once per turn. When time ran out, the isolated team returned to the stage, and acted out the same words as the first team. The team that guessed the most words in their own minute won the round, and the first team to win two rounds won the game.
If a round ended in a tie, a tiebreaker round was played in which both teams had 30 seconds to act out three words. The team doing that in the fastest time won.
Format #2
Towards the end of the show's run, the method to win the game had changed. In this format, a team had to correctly convey

https://en.wikipedia.org/wiki/Convection%20heater
|
A convection heater (otherwise known as a convector heater) is a heater that uses convection currents to heat and circulate air. These currents circulate throughout the body of the appliance and across its heating element. This process, following the principle of thermal conduction, heats up the air, reducing its density relative to colder air and causing it to rise.
As heated air molecules rise, they displace cooler air molecules down towards the heating appliance. The displaced cool air is heated as a result, decreases in density, rises, and repeats the cycle.
History
Ancient heating systems, including hearths, furnaces, and stoves, operated primarily through convection. Fixed central hearths, which were first excavated and retrieved in Greece, date back to 2500BC, while crude fireplaces were used as early as the 800sAD and in the 13th century, when castles in Europe were built with fireplaces with a crude form of chimney.
Developments in convection heating technology included the publication of the very first manual on fireplace design called Mechanique du Feu in 1713, the creation of stoves with thermostatic control in 1849, and the rise of numerous cast iron stove manufacturers during the American Civil War.
The Model "S", illustrated by the Sala Heater & Mantel Co. in Dallas, Texas in 1924, is an example of an early model of a convection space heater. This model consisted of three stoves and was considered to be a highly efficient radiant type of gas heater at th

https://en.wikipedia.org/wiki/Pallas%27s%20long-tongued%20bat
|
Pallas's long-tongued bat (Glossophaga soricina) is a South and Central American bat with a fast metabolism that feeds on nectar.
Metabolism
It has the fastest metabolism ever recorded in a mammal, similar to those of hummingbirds. Although it uses 50% of its stored fat over the course of a day, over 80% of its energy comes directly from the simple sugars that compose its diet of nectar, without being stored in any form. It will also feed on pollen, flower parts, fruit and insects.
Tongue
A 2013 study determined that their tongues have a mopping ability that is powered by blood, a phenomenon unique in nature. Elongated hairs at the tongue's tip, which normally lie flat, become engorged with blood when the tongue is protruded. As a result, the hairs stand in erect rows, perpendicular to the tongue. The tongue tip increases by over 50 percent in length, contracting its width to squeeze enlarged vascular sinuses along the tongue's length, that are directly connected to the hairs. During this process tissue capillaries turn from pink (little blood) to dark red. The blood vessel networks that enter the tip of the tongue are fringed by muscle fibers, which contract to compress the blood vessels and displace blood towards the tip. The efficiency of this feeding mechanism is believed to enable the bats' survival on limited food sources.

https://en.wikipedia.org/wiki/Disintegration%20theorem
|
In mathematics, the disintegration theorem is a result in measure theory and probability theory. It rigorously defines the idea of a non-trivial "restriction" of a measure to a measure zero subset of the measure space in question. It is related to the existence of conditional probability measures. In a sense, "disintegration" is the opposite process to the construction of a product measure.
Motivation
Consider the unit square in the Euclidean plane , . Consider the probability measure defined on by the restriction of two-dimensional Lebesgue measure to . That is, the probability of an event is simply the area of . We assume is a measurable subset of .
Consider a one-dimensional subset of such as the line segment . has -measure zero; every subset of is a -null set; since the Lebesgue measure space is a complete measure space,
While true, this is somewhat unsatisfying. It would be nice to say that "restricted to" is the one-dimensional Lebesgue measure , rather than the zero measure. The probability of a "two-dimensional" event could then be obtained as an integral of the one-dimensional probabilities of the vertical "slices" : more formally, if denotes one-dimensional Lebesgue measure on , then
for any "nice" . The disintegration theorem makes this argument rigorous in the context of measures on metric spaces.
Statement of the theorem

https://en.wikipedia.org/wiki/Protein%20kinase%20R
|
Protein kinase RNA-activated also known as protein kinase R (PKR), interferon-induced, double-stranded RNA-activated protein kinase, or eukaryotic translation initiation factor 2-alpha kinase 2 (EIF2AK2) is an enzyme that in humans is encoded by the EIF2AK2 gene on chromosome 2. PKR is a serine/tyrosine kinase that is 551 amino acids long.
PKR is inducible by various mechanisms of stress and protects against viral infections. It also has a role in several signaling pathways.
Mechanism of action
Protein kinase-R is activated by double-stranded RNA (dsRNA), introduced to the cells by a viral infection. In situations of viral infection, the dsRNA created by viral replication and gene expression binds to the N-terminal domain, activating the protein. PKR activation via dsRNA is length dependent, requiring the dsRNA to be 30 bp in length to bind to PKR molecules. However, excess dsRNA can diminish activation of PKR. Binding to dsRNA is believed to activate PKR by inducing dimerization of the kinase domains and subsequent auto-phosphorylation reactions. PKR can also be activated by the protein PACT via phosphorylation of S287 on its M3 domain. The promoter region of PKR has interferon-stimulated response elements to which Type I interferons (IFN) bind to induce the transcription of PKR genes. Some research suggests that PKR can be stimulated by heat shock proteins, heparin, growth factors, bacterial infection, pro-inflammatory cytokines, reactive oxygen species, DNA damage, mech

WPLO ("La Bonita 610 AM") is an Atlanta area AM broadcasting station, licensed to Grayson, Georgia, that broadcasts Spanish language music programming. It transmits at a frequency of 610 kHz with 1,500 Watts of power during the daytime and 225 Watts during nighttime using a non-directional antenna. WPLO is a Class-D AM broadcasting station according to the Federal Communications Commission. The station has applied to the Federal Communications Commission to change its licensed city to Lawrenceville, Georgia, the location of its current transmitting facility and tower.
History
The radio station is not to be confused with the other AM broadcasting station in the Atlanta radio market which carried the WPLO call signs from 1959 until 1987. The 610 kHz station adopted the WPLO call signs in 1990 when it switched from its previous WGNN call signs. WLAW were the original call signs of this station before switching to WGNN in 1987.
The station was branded as "RadioMex 610 Atlanta" until 2009. Late in 2009, the station changed to the "La Bonita 610 AM" branding.

https://en.wikipedia.org/wiki/Ternary%20complex
|
A ternary complex is a protein complex containing three different molecules that are bound together. In structural biology, ternary complex can also be used to describe a crystal containing a protein with two small molecules bound, for example cofactor and substrate; or a complex formed between two proteins and a single substrate. In Immunology, ternary complex can refer to the MHC–peptide–T-cell-receptor complex formed when T cells recognize epitopes of an antigen.
Some other example can be taken like ternary complex while eukaryotic translation, in which ternary complex is composed of eIF-3 & eIF-2 + Ribosome 40s subunit+ tRNAi.
A ternary complex can be a complex formed between two substrate molecules and an enzyme. This is seen in multi-substrate enzyme-catalyzed reactions where two substrates and two products can be formed. The ternary complex is an intermediate between the product formation in this type of enzyme-catalyzed reactions. An example for a ternary complex is seen in random-order mechanism or a compulsory-order mechanism of enzyme catalysis for multi substrates.
The term ternary complex can also refer to a polymer formed by electrostatic interactions.

Riboflavin carrier proteins (RFCPs) together with human serum albumin transport flavin mononucleotide (FMN) in the blood circuit. RFCPs are important in pregnancy.
Studies from India have identified a riboflavin carrier protein (RCP) present in bird (e.g., chicken) eggs, which is considered to be specific for riboflavin, and is essential for normal embryological development. If this protein is rendered ineffective (e.g., by immuno-neutralization) by treatment of the bird with a specific antibody, then embryonic development ceases and the embryo dies. A genetic mutant lacking RCP is likewise infertile. A homologous protein, which can be rendered ineffective by the antibody to pure chicken riboflavin carrier protein, has been shown to occur in several mammalian species, including two species of monkeys, and also in humans. Very recent studies have suggested that circulating RCP levels and the immunohistochemical staining of RCP in biopsy specimens may provide new markers for breast cancer diagnosis and prognosis. Termination of pregnancy has been demonstrated by immuno-neutralization of RCP in monkeys. There remains some controversy over the roles of RCP, however, the other, less specific riboflavin binders in blood, including gamma-gobulins, also seem to play an important role. These studies have provided an intriguing example of the role of specific vitamin-transporting mechanisms, designed to ensure that the vitamin needs of the developing embryo will be efficiency met.

https://en.wikipedia.org/wiki/A-normal%20form
|
In computer science, A-normal form (abbreviated ANF, sometimes expanded as administrative normal form) is an intermediate representation of programs in functional programming language compilers.
In ANF, all arguments to a function must be trivial (constants or variables). That is, evaluation of each argument must halt immediately.
ANF was introduced by Sabry and Felleisen in 1992 as a simpler alternative to continuation-passing style (CPS). Some of the advantages of using CPS as an intermediate representation are that optimizations are easier to perform on programs in CPS than in the source language, and that it is also easier for compilers to generate machine code for programs in CPS. Flanagan et al. showed how compilers could use ANF to achieve those same benefits with one source-level transformation; in contrast, for realistic compilers the CPS transformation typically involves additional phases, for example, to simplify CPS terms.
Grammar
Consider the pure λ-calculus with weak reduction and let-expressions. The ANF restriction is enforced by
allowing only constants, λ-terms, and variables, to serve as arguments of function applications, and
requiring that the result of a non-trivial expression be captured by a let-bound variable or returned from a function.
The following BNF grammar describes the syntax of λ-expressions modified to support the constraints of ANF:
EXP ::= VAL
| let VAR = VAL in EXP
| let VAR = VAL VAL in EXP

CFLAGS and CXXFLAGS are either the name of environment variables or of Makefile variables that can be set to specify additional switches to be passed to a compiler in the process of building computer software. FFLAGS fulfills a similar role.
These variables are usually set inside a Makefile and are then appended to the command line when the compiler is invoked. If they are not specified in the Makefile, then they will be read from the environment, if present. Tools like autoconf's ./configure script will usually pick them up from the environment and write them into the generated Makefiles. Some package install scripts, like SDL, allow CFLAGS settings to override their normal settings (instead of append to them), so setting CFLAGS can cause harm in this case.
CFLAGS enables the addition of switches for the C compiler, while CXXFLAGS is meant to be used when invoking a C++ compiler. Similarly, a variable CPPFLAGS exists with switches to be passed to the C or C++ preprocessor. Similarly, FFLAGS enables the addition of switches for a Fortran compiler.
These variables are most commonly used to specify optimization or debugging switches to a compiler, as for example -g, -O2 or (GCC-specific) -march=athlon.

https://en.wikipedia.org/wiki/Ceramic%20membrane
|
Ceramic membranes are a type of artificial membranes made from inorganic materials (such as alumina, titania, zirconia oxides, silicon carbide or some glassy materials). They are used in membrane operations for liquid filtration.
By contrast with polymeric membranes, they can be used in separations where aggressive media (acids, strong solvents) are present. They also have excellent thermal stability which makes them usable in high-temperature membrane operations.
Like polymeric membranes, they are either dense or porous.
Researchers have studied ceramic membranes for potential applications in wastewater treatment, gas separation, and membrane reactors. Ceramic membranes typically last longer than polymeric membranes which are more commonly used for these applications. Currently ceramic membranes have not seen widespread usage mainly due to their high cost of production.
Configurations include tubular cross flow and dead-end membranes as well as flat sheet membranes.
Dense membranes
Dense ceramic membranes are used for the purpose of gas separation. Examples are the separation of oxygen from air, or the separation of hydrogen gas from a mixture. Dense ceramic membranes have been studied for process intensification applications to reduce the energy consumption of many technologies used in the petroleum industry. One such application is membrane reactors, through the use of dense oxygen permeable membranes.

https://en.wikipedia.org/wiki/Fisher%20kernel
|
In statistical classification, the Fisher kernel, named after Ronald Fisher, is a function that measures the similarity of two objects on the basis of sets of measurements for each object and a statistical model. In a classification procedure, the class for a new object (whose real class is unknown) can be estimated by minimising, across classes, an average of the Fisher kernel distance from the new object to each known member of the given class.
The Fisher kernel was introduced in 1998. It combines the advantages of generative statistical models (like the hidden Markov model) and those of discriminative methods (like support vector machines):
generative models can process data of variable length (adding or removing data is well-supported)
discriminative methods can have flexible criteria and yield better results.
Derivation
Fisher score
The Fisher kernel makes use of the Fisher score, defined as
with θ being a set (vector) of parameters. The function taking θ to log P(X|θ) is the log-likelihood of the probabilistic model.
Fisher kernel
The Fisher kernel is defined as
with being the Fisher information matrix.
Applications
Information retrieval
The Fisher kernel is the kernel for a generative probabilistic model. As such, it constitutes a bridge between generative and probabilistic models of documents. Fisher kernels exist for numerous models, notably tf–idf, Naive Bayes and probabilistic latent semantic analysis.

The Cray SV1 is a vector processor supercomputer from the Cray Research division of Silicon Graphics introduced in 1998. The SV1 has since been succeeded by the Cray X1 and X1E vector supercomputers. Like its predecessor, the Cray J90, the SV1 used CMOS processors, which lowered the cost of the system, and allowed the computer to be air-cooled. The SV1 was backwards compatible with J90 and Y-MP software, and ran the same UNIX-derived UNICOS operating system. The SV1 used Cray floating point representation, not the IEEE 754 floating point format used on the Cray T3E and some Cray T90 systems.
Unlike earlier Cray designs, the SV1 included a vector cache. It also introduced a feature called multi-streaming, in which one processor from each of four processor boards work together to form a virtual processor with four times the performance. The SV1 processor was clocked at 300 MHz. Later variants of the SV1, the SV1e and SV1ex, ran at 500 MHz, the latter also having faster memory and support for the SSD-I Solid-State Storage Device. Systems could include up to 32 processors with up to 512 shared memory buses.
Multiple SV1 cabinets could be clustered together using the GigaRing I/O channel, which also provided connection to HIPPI, FDDI, ATM, Ethernet and SCSI devices for network, disk, and tape services. In theory, up to 32 nodes could be clustered together, offering up to one teraflops in theoretical peak performance.

https://en.wikipedia.org/wiki/Triphenylphosphine%20oxide
|
Triphenylphosphine oxide (often abbreviated TPPO) is the organophosphorus compound with the formula OP(C6H5)3, also written as Ph3PO or PPh3O (Ph = C6H5). This colourless crystalline compound is a common but potentially useful waste product in reactions involving triphenylphosphine. It is a popular reagent to induce the crystallizing of chemical compounds.
Structure and properties
Ph3PO is a tetrahedral molecule related to POCl3. The oxygen center is relatively basic. The rigidity of the backbone and the basicity of the oxygen center make this species a popular agent to crystallize otherwise difficult to crystallize molecules. This trick is applicable to molecules that have acidic hydrogen atoms, e.g. phenols.
Up to now, several modifications of Ph3PO have been found: For example, a monoclinic form crystalizes in the space group P21/c with Z = 4 and a = 15.066(1) Å, b = 9.037(2) Å, c = 11.296(3) Å, and β = 98.47(1)°. The orthorhombic modification crystallizes in the space group Pbca with Z = 4 and 29.089(3) Å, b = 9.1347(9), c = 11.261(1) Å.
TPPO's unique application as a heat-diffuser in many electronic devices is used by law enforcement to train electronics-sniffing dogs.
As a byproduct of organic synthesis
Ph3PO is a byproduct of many useful reactions in organic synthesis including the Wittig, Staudinger, and Mitsunobu reactions. It is also formed when PPh3Cl2 is employed to convert alcohols into alkyl chlorides:
Ph3PCl2 + ROH → Ph3PO + HCl + RCl

Collagen alpha-1 (XXVII) chain (COL27A1) is a protein that in humans is encoded by the COL27A1 gene.
COL27A1 is a type XXVII collagen. It was discovered by James Pace. This gene appears to be turned on in cartilage, the eye, and in the ear. Type XXVII collagen is related to the "fibrillar" class of collagens and may play a role in development of the skeleton.
Fibrillar collagens, such as COL27A1, compose one of the most ancient families of extracellular matrix molecules. They form major structural elements in extracellular matrices of cartilage, skin, and tendon.
Location
COL27A1 is located on chromosome 9 in homo sapiens specifically on spot number 32.

|
Contactless payment systems are credit cards and debit cards, key fobs, smart cards, or other devices, including smartphones and other mobile devices, that use radio-frequency identification (RFID) or near-field communication (NFC, e.g. Samsung Pay, Apple Pay, Google Pay, Fitbit Pay, or any bank mobile application that supports contactless payment) for making secure payments. The embedded integrated circuit chip and antenna enable consumers to wave their card, fob, or handheld device over a reader at the Point-of-sale terminal. Contactless payments are made in close physical proximity, unlike other types of mobile payments which use broad-area cellular or WiFi networks and do not involve close physical proximity.
EMV is a common standard used by major credit card and smartphone companies for use in general commerce. Contactless smart cards that function as stored-value cards are becoming popular for use as transit system farecards, such as the Oyster card or RioCard. These can often store non-currency value (such as monthly passes), in additional to fare value purchased with cash or electronic payment.
Tokenisation is a newer concept of encapsulating a card issuers details within a hardware device application such as via Apple Pay app on iPhones.
Some suppliers claim that transactions can be almost twice as fast as a conventional cash, credit, or debit card purchase. Because no signature or PIN verification is typically required, contactless purchases are usually limite

Phenotype mixing is a form of interaction between two viruses each of which holds its own unique genetic material. The two particles "share" coat proteins, therefore each has a similar assortment of identifying surface proteins, while having different genetic material.
In other words; non-genetic interaction in which virus particles released from a cell that is infected with two different viruses have components from both the infecting agents, but with a genome from one of them.

The 68HC16 (also abbreviated as HC16) is a highly modular microcontroller family based on the CPU16 16-bit core made by Freescale Semiconductor (formerly known as Motorola Semiconductor). The CPU16 core is a true 16-bit design, with an architecture that is very familiar to 68HC11 (HC11) users. The resemblances to the HC11 core design are a deliberate move to provide
an upgrade path for those 8-bit 68HC11 designs that require the increased power of a 16-bit CPU. Many features of the HC16 and the CPU16 core are new to HC11 users.
The HC16 provides a software upgrade path for HC11 users while giving full hardware compatibility with the asynchronous address and data bus found on the 32-bit microprocessors.

The Rabbit 2000 is a high-performance 8-bit microcontroller designed by Rabbit Semiconductor for embedded system applications. Rabbit Semiconductor has been bought by Digi International, which is since selling the Rabbit microcontrollers and hardware based on them. The instruction set is based on the original Z80 microprocessor, but with some additions of new instructions as well as deletions of some instructions. Among the Z80 instructions missing in the Rabbit, cpir is particularly notable, since it allows for much more efficient implementations of some often-used standard C functions such as strlen(), strnlen() and memchr(). According to the Rabbit documentation, it executes its instructions 5 times faster than the original Z80 microprocessor, that is, similarly to the Zilog eZ80.
The Rabbit 3000 is a variant of the Rabbit 2000 with the same core, but more powerful integrated peripherals. The Rabbit 3000A variant adds a small number of additional instructions for I/O and large integer arithmetic. The Rabbit 4000 again adds more integrated peripherals. The further derivatives, starting with the Rabbit 5000 have a substantially different architecture.
Most of the Rabbit microcontrollers come with built-in flash memory and SRAM. They also have ADC and timers built-in.

The Rabbit 2000 is supported by the free (GPL) Small Device C Compiler and Z88DK.

https://en.wikipedia.org/wiki/Vertex%20%28curve%29
|
In the geometry of plane curves, a vertex is a point of where the first derivative of curvature is zero. This is typically a local maximum or minimum of curvature, and some authors define a vertex to be more specifically a local extremum of curvature. However, other special cases may occur, for instance when the second derivative is also zero, or when the curvature is constant. For space curves, on the other hand, a vertex is a point where the torsion vanishes.
Examples
A hyperbola has two vertices, one on each branch; they are the closest of any two points lying on opposite branches of the hyperbola, and they lie on the principal axis. On a parabola, the sole vertex lies on the axis of symmetry and in a quadratic of the form:
it can be found by completing the square or by differentiation. On an ellipse, two of the four vertices lie on the major axis and two lie on the minor axis.
For a circle, which has constant curvature, every point is a vertex.
Cusps and osculation
Vertices are points where the curve has 4-point contact with the osculating circle at that point. In contrast, generic points on a curve typically only have 3-point contact with their osculating circle. The evolute of a curve will generically have a cusp when the curve has a vertex; other, more degenerate and non-stable singularities may occur at higher-order vertices, at which the osculating circle has contact of higher order than four. Although a single generic curve will not have any higher-order verti

Derek Ashworth Denton (27 May 1924 – 18 November 2022) was an Australian scientist who elucidated the regulation of electrolytes in extracellular fluid, the hormones controlling this regulation, particularly aldosterone, and the instinctive behaviours controlling intake of water and salts. He was cited in 1995 at election to the U.S. National Academy of Sciences as the world’s leading authority on the regulation of salt and water metabolism and relevant endocrine control mechanisms. He was one of Australia’s most eminent scientists.
Career
Denton was the founding Director and Emeritus Director of the Howard Florey Institute, Honorary Professor at the University of Melbourne and a consultant at the Baker Research Institute. Denton's last book is The Primordial Emotions: The Dawning of Consciousness.
Research
Three months after medical graduation in 1947, he made a basic discovery on kidney function at the Royal Melbourne Hospital. In the face of profuse alkaline drainage (Na+ in excess of Cl- relative to extracellular proportions) from a pancreatic fistula (2-3 litres/day) the patient’s kidneys primarily regulated the ionic pattern of the extra cellular fluid – not plasma concentration or the load of ions to the kidney tubules. As the fistula drained, blood pressure declined, respiration increased, and Cl- excretion in urine increased despite decline in plasma Cl- level below the so called “renal threshold “.

The Cray J90 series (code-named Jedi during development) was an air-cooled vector processor supercomputer first sold by Cray Research in 1994. The J90 evolved from the Cray Y-MP EL minisupercomputer, and is compatible with Y-MP software, running the same UNICOS operating system. The J90 supported up to 32 CMOS processors with a 10 ns (100 MHz) clock. It supported up to 4 GB of main memory and up to 48 GB/s of memory bandwidth, giving it considerably less performance than the contemporary Cray T90, but making it a strong competitor to other technical computers in its price range. All input/output in a J90 system was handled by an IOS (Input/Output Subsystem) called IOS Model V. The IOS-V was based on the VME64 bus and SPARC I/O processors (IOPs) running the VxWorks RTOS. The IOS was programmed to emulate the IOS Model E, used in the larger Cray Y-MP systems, in order to minimize changes in the UNICOS operating system. By using standard VME boards, a wide variety of commodity peripherals could be used.
The J90 was available in three basic configurations, the J98 with up to eight processors, the J916 with up to 16 processors, and the J932 with up to 32 processors.
Each J90 processor was composed of two chips - one for the scalar portion of the processor, and the other for the vector portion. The scalar chip was also notable for including a small (128 word) data cache to enhance scalar performance. (Cray machines have always had instruction caching.)

The Cray X1 is a non-uniform memory access, vector processor supercomputer manufactured and sold by Cray Inc. since 2003. The X1 is often described as the unification of the Cray T90, Cray SV1, and Cray T3E architectures into a single machine. The X1 shares the multistreaming processors, vector caches, and CMOS design of the SV1, the highly scalable distributed memory design of the T3E, and the high memory bandwidth and liquid cooling of the T90.
The X1 uses a 1.2 ns (800 MHz) clock cycle, and 8-wide vector pipes in MSP mode, offering a peak speed of 12.8 gigaflops per processor. Air-cooled models are available with up to 64 processors. Liquid-cooled systems scale to a theoretical maximum of 4096 processors, comprising 1024 shared-memory nodes connected in a two-dimensional torus network, in 32 frames. Such a system would supply a peak speed of 50 teraflops. The largest unclassified X1 system was the 512 processor system at Oak Ridge National Laboratory, though this has since been upgraded to an X1E system.
The X1 can be programmed either with widely used message passing software like MPI and PVM, or with shared-memory languages like Unified Parallel C programming language or Co-array Fortran. The X1 runs an operating system called UNICOS/mp which shares more with the SGI IRIX operating system than it does with the UNICOS found on prior generation Cray machines.
In 2005, Cray released the X1E upgrade, which uses dual-core processors, allowing two quad-processor nodes to fi

https://en.wikipedia.org/wiki/Luhn%20mod%20N%20algorithm
|
The Luhn mod N algorithm is an extension to the Luhn algorithm (also known as mod 10 algorithm) that allows it to work with sequences of values in any even-numbered base. This can be useful when a check digit is required to validate an identification string composed of letters, a combination of letters and digits or any arbitrary set of characters where is divisible by 2.
Informal explanation
The Luhn mod N algorithm generates a check digit (more precisely, a check character) within the same range of valid characters as the input string. For example, if the algorithm is applied to a string of lower-case letters (a to z), the check character will also be a lower-case letter. Apart from this distinction, it resembles very closely the original algorithm.
The main idea behind the extension is that the full set of valid input characters is mapped to a list of code-points (i.e., sequential integers beginning with zero). The algorithm processes the input string by converting each character to its associated code-point and then performing the computations in mod N (where is the number of valid input characters). Finally, the resulting check code-point is mapped back to obtain its corresponding check character.
Limitation
The Luhn mod N algorithm only works where is divisible by 2. This is because there is an operation to correct the value of a position after doubling its value which does not work where is not divisible by 2. For applications using the English alphabet thi

The Hitachi HD44780 LCD controller is an alphanumeric dot matrix liquid crystal display (LCD) controller developed by Hitachi in the 1980s. The character set of the controller includes ASCII characters, Japanese Kana characters, and some symbols in two 40 character lines. Using an extension driver, the device can display up to 80 characters. Numerous third-party displays are compatible with its 16-pin interface and instruction set, making it a popular and cheap LCD driver.
Architecture
The Hitachi HD44780 LCD controller is limited to monochrome text displays and is often used in copiers, fax machines, laser printers, industrial test equipment, and networking equipment, such as routers and storage devices.
Compatible LCD screens are manufactured in several standard configurations. Common sizes are one row of eight characters (8×1), and 16×2, 20×2 and 20×4 formats. Larger custom sizes are made with 32, 40 and 80 characters and with 1, 2, 4 or 8 lines. The most commonly manufactured larger configuration is 40×4 characters, which requires two individually addressable HD44780 controllers with expansion chips as a single HD44780 chip can only address up to 80 characters.
Character LCDs may have a backlight, which may be LED, fluorescent, or electroluminescent. The nominal operating voltage for LED backlights is 5V at full brightness, with dimming at lower voltages dependent on the details such as LED color. Non-LED backlights often require higher voltages.

MUSIC (MUltiple SIgnal Classification) is an algorithm used for frequency estimation and radio direction finding.
History
In many practical signal processing problems, the objective is to estimate from measurements a set of constant parameters upon which the received signals depend. There have been several approaches to such problems including the so-called maximum likelihood (ML) method of Capon (1969) and Burg's maximum entropy (ME) method. Although often successful and widely used, these methods have certain fundamental limitations (especially bias and sensitivity in parameter estimates), largely because they use an incorrect model (e.g., AR rather than special ARMA) of the measurements.
Pisarenko (1973) was one of the first to exploit the structure of the data model, doing so in the context of estimation of parameters of complex sinusoids in additive noise using a covariance approach. Schmidt (1977), while working at Northrop Grumman and independently Bienvenu and Kopp (1979) were the first to correctly exploit the measurement model in the case of sensor arrays of arbitrary form. Schmidt, in particular, accomplished this by first deriving a complete geometric solution in the absence of noise, then cleverly extending the geometric concepts to obtain a reasonable approximate solution in the presence of noise. The resulting algorithm was called MUSIC (MUltiple SIgnal Classification) and has been widely studied.

Pisarenko harmonic decomposition, also referred to as Pisarenko's method, is a method of frequency estimation. This method assumes that a signal, , consists of complex exponentials in the presence of white noise. Because the number of complex exponentials must be known a priori, it is somewhat limited in its usefulness.
Pisarenko's method also assumes that values of the autocorrelation matrix are either known or estimated. Hence, given the autocorrelation matrix, the dimension of the noise subspace is equal to one and is spanned by the eigenvector corresponding to the minimum eigenvalue. This eigenvector is orthogonal to each of the signal vectors.
The frequency estimates may be determined by setting the frequencies equal to the angles of the roots of the polynomial
or the location of the peaks in the frequency estimation function (or the pseudo-spectrum)

History
The method was first discovered in 1911 by Constantin Carathéodory, then rediscovered by Vladilen Fedorovich Pisarenko in 1973 while examining the problem of estimating the frequencies of complex signals in white noise. He found that the frequencies could be derived from the eigenvector corresponding to the minimum eigenvalue of the autocorrelation matrix.

https://en.wikipedia.org/wiki/Interleukin%2011
|
Interleukin 11 (IL-11 or adipogenesis inhibitory factor) is a protein that in humans is encoded by the IL11 gene.
IL-11 is a cytokine that was first isolated in 1990 from bone marrow-derived fibrocyte-like stromal cells. It was initially thought to be important for hematopoiesis, notably for megakaryocyte maturation, but subsequently shown to be redundant for platelets, and for other blood cell types, in both mice and humans. It was developed as a recombinant protein (rhIL-11) as the drug substance oprelvekin.
The human IL-11 gene, consisting of 5 exons and 4 introns, is located on chromosome 19, and encodes a 23 kDa protein. IL-11 is a member of the IL-6-type cytokine family, distinguished based on their use of the common co-receptor gp130. Signal specificity is provided by the IL-11Rα subunit which is expressed at high levels in fibroblasts and other stromal cells but not immune cells, unlike IL6 receptors that are expressed at highest levels in immune cells and lowly expressed in stromal cells.
Downstream signalling
Signal transduction is initiated upon binding of IL-11 to IL-11Ralpha and gp130, facilitating the formation of higher order structures involving dimers of gp130:Il-11:Il11RA complexes. In some instances, in epithelial-derived cells and cancer cell lines, this permits gp130-associated Janus kinases (JAK) activation and downstream STAT-mediated transcriptional activities. In other instances, in stromal cells, IL-11 activates non-canonical MAPK/ERK-dependent

https://en.wikipedia.org/wiki/Equating%20coefficients
|
In mathematics, the method of equating the coefficients is a way of solving a functional equation of two expressions such as polynomials for a number of unknown parameters. It relies on the fact that two expressions are identical precisely when corresponding coefficients are equal for each different type of term. The method is used to bring formulas into a desired form.
Example in real fractions
Suppose we want to apply partial fraction decomposition to the expression:
that is, we want to bring it into the form:
in which the unknown parameters are A, B and C.
Multiplying these formulas by x(x − 1)(x − 2) turns both into polynomials, which we equate:
or, after expansion and collecting terms with equal powers of x:
At this point it is essential to realize that the polynomial 1 is in fact equal to the polynomial 0x2 + 0x + 1, having zero coefficients for the positive powers of x. Equating the corresponding coefficients now results in this system of linear equations:
Solving it results in:
Example in nested radicals
A similar problem, involving equating like terms rather than coefficients of like terms, arises if we wish to de-nest the nested radicals to obtain an equivalent expression not involving a square root of an expression itself involving a square root, we can postulate the existence of rational parameters d, e such that
Squaring both sides of this equation yields:
To find d and e we equate the terms not involving square roots, so and equate the parts involv

Helaman Rolfe Pratt Ferguson (born 1940 in Salt Lake City, Utah) is an American sculptor and a digital artist, specifically an algorist. He is also well known for his development of the PSLQ algorithm, an integer relation detection algorithm.
Early life and education
Ferguson's mother died when he was about three and his father went off to serve in the Second World War. He was adopted by an Irish immigrant and raised in New York. He learned to work with his hands in an old-world style with earthen materials from his adoptive father who was a carpenter and stonemason by trade. An art-inclined math teacher in high school helped him develop his dual interests in math and art.
Ferguson is a graduate of Hamilton College, a liberal arts school in New York. In 1971, he received a Ph.D. in mathematics from the University of Washington.
Work
In 1977, Ferguson and another mathematician, Rodney Forcade, developed an algorithm for integer relation detection. It was the first viable generalization of the Euclidean algorithm for three or more variables. He later developed a more notable integer relation detection algorithm - the PSLQ algorithm - which was selected as one of the "Top Ten Algorithms of the Century" by Jack Dongarra and Francis Sullivan.
In January 2014, Ferguson and his wife Claire Ferguson delivered an MAA Invited Address, titled "Mathematics in Stone and Bronze," at the Joint Math Meetings in Baltimore Maryland. He is an active artist, often representing mathematical

https://en.wikipedia.org/wiki/Geomembrane
|
A geomembrane is very low permeability synthetic membrane liner or barrier used with any geotechnical engineering related material so as to control fluid (liquid or gas) migration in a human-made project, structure, or system. Geomembranes are made from relatively thin continuous polymeric sheets, but they can also be made from the impregnation of geotextiles with asphalt, elastomer or polymer sprays, or as multilayered bitumen geocomposites. Continuous polymer sheet geomembranes are, by far, the most common.
Manufacturing
The manufacturing of geomembranes begins with the production of the raw materials, which include the polymer resin, and various additives such as antioxidants, plasticizers, fillers, carbon black, and lubricants (as a processing aid). These raw materials (i.e., the "formulation") are then processed into sheets of various widths and thickness by extrusion, calendering, and/or spread coating.
Geomembranes dominate the sales of geosynthetic products, at US$1.8 billion per year worldwide, which is 35% of the market. The US market is currently divided between HDPE, LLDPE, fPP, PVC, CSPE-R, EPDM-R and others (such as EIA-R), and can be summarized as follows: (Note that M m2 refers to millions of square meters.)
high-density polyethylene (HDPE) ~ 35% or 105 M m2
linear low-density polyethylene (LLDPE) ~ 25% or 75 M m2
polyvinyl chloride (PVC) ~ 25% or 75 M m2

Patrick Alfred Pierce Moran FRS (14 July 1917 – 19 September 1988) was an Australian statistician who made significant contributions to probability theory and its application to population and evolutionary genetics.
Early years
Patrick Moran was born in Sydney and was the only child of Herbert Michael Moran (b. 1885 in Sydney, d. 1945 in Cambridge UK), a prominent surgeon and captain of the first Wallabies, and Eva Mann (b. 1887 in Sydney, d. 1977 in Sydney). Patrick did have five other siblings, but they all died at or shortly after birth. He completed his high school studies in Bathurst, in three and a half years instead of the normal five-year course. At age 16, in 1934, he commenced study at the University of Sydney where he studied chemistry, math and physics, graduating with first class honours in mathematics in 1937. Following graduation he went to study at Cambridge University from 1937 to 1939, his supervisors noted that he was not a good mathematician and the outbreak of World War II interrupted his studies. He graduated with an MA (by proxy) from St John's College, Cambridge, on 22 January 1943 and continued his studies there from 1945 to 1946. He was admitted to Balliol College, Oxford University, on 3 December 1946. He was awarded an MA, from Oxford University, by incorporation in 1947.

https://en.wikipedia.org/wiki/Paratransgenesis
|
Paratransgenesis is a technique that attempts to eliminate a pathogen from vector populations through transgenesis of a symbiont of the vector. The goal of this technique is to control vector-borne diseases. The first step is to identify proteins that prevent the vector species from transmitting the pathogen. The genes coding for these proteins are then introduced into the symbiont, so that they can be expressed in the vector. The final step in the strategy is to introduce these transgenic symbionts into vector populations in the wild. One use of this technique is to prevent mortality for humans from insect-borne diseases. Preventive methods and current controls against vector-borne diseases depend on insecticides, even though some mosquito breeds may be resistant to them. There are other ways to fully eliminate them. “Paratransgenesis focuses on utilizing genetically modified insect symbionts to express molecules within the vector that are deleterious to pathogens they transmit.” The acidic bacteria Asaia symbionts are beneficial in the normal development of mosquito larvae; however, it is unknown what Asais symbionts do to adult mosquitoes.
The first example of this technique used Rhodnius prolixus which is associated with the symbiont Rhodococcus rhodnii. R. prolixus is an important insect vector of Chagas disease that is caused by Trypanosoma cruzi. The strategy was to engineer R. rhodnii to express proteins such as Cecropin A that are toxic to T. cruzi or that block the

Celacade was a non-drug, device-based treatment also known as Immune Modulation Therapy (IMT), developed by the Canadian-based biotherapeutics company Vasogen, Inc. for chronic heart failure and peripheral artery disease. Blood was piped through the device, where it was exposed to heat, ultraviolet light, and ozone, in the hope that this oxidative stress would trigger an anti-inflammatory immunomodulation response.
Despite some promising early results and one positive result in subgroup analysis, the technique usually did not produce the hoped-for clinically significant results.
Research history
At the World Congress of Cardiology in September 2006 the Advanced Chronic Heart Failure Clinical Assessment of Immune Modulation Therapy (ACCLAIM) a phase III randomized, double-blind, placebo-controlled clinical trial involving some 2408 patients in 7 countries with left ventricular ejection fraction of 30% or less, reported that only one subgroup – patients with a previous cardiovascular event – benefited from the treatment. These people were 39% less likely to die or be hospitalized due to a heart attack or stroke and tended to have improved quality of life.
Marketing approval
Vasogen in collaboration with Grupo Ferrer Internacional has regulatory approval to market Celacade as a medical device for the treatment of chronic heart failure in the European Union and Latin America.

https://en.wikipedia.org/wiki/Neuromorphology
|
Neuromorphology (from Greek νεῦρον, neuron, "nerve"; μορφή, morphé, "form"; -λογία, -logia, “study of”) is the study of nervous system form, shape, and structure. The study involves looking at a particular part of the nervous system from a molecular and cellular level and connecting it to a physiological and anatomical point of view. The field also explores the communications and interactions within and between each specialized section of the nervous system.
Morphology is distinct from morphogenesis. Morphology is the study of the shape and structure of biological organisms, while morphogenesis is the study of the biological development of the shape and structure of organisms. Therefore, neuromorphology focuses on the specifics of the structure of the nervous system and not the process by which the structure was developed. Neuromorphology and morphogenesis, while two different entities, are nonetheless closely linked.
History
Progress in defining the morphology of nerve cells has been slow in its development. It took nearly a century after the acceptance of the cell as the basic unit of life before researchers could agree upon the shape of a neuron. It was originally thought to be an independent globular corpuscle suspended along nerve fibers that looped and coiled. It was not until the first successful microdissection of a whole nerve cell by Otto Deiters in 1865 that the separate dendrites and axon could be distinguished. At the end of the 19th century, new techniques,

|
John Wood (1745 – July 1816 at Seal, Kent) was an English cricketer who played for Kent. His career began in the 1760s before first-class statistics began to be recorded and his known first-class career spans the 1772 to 1783 seasons.
He has often been confused with his namesake who played for Surrey at the same time. Although Wood is credited with 12 first-class appearances by CricketArchive, there are only 10 which can definitely be attributed to him. Using the data in Scores and Biographies, there were 12 matches in which a player known only as "Wood" took part, with Wood of Surrey specifically recorded in 13.
According to John Nyren, Wood of Kent was a "change bowler who was tall, stout, bony and a very good general player". According to H T Waghorn, he suffered a serious knee injury in 1773 and there were fears of amputation being necessary. However, he was playing again in 1774 so things cannot have been as bad as they first seemed.
The first time a John Wood is mentioned in the sources is when one plays for Caterham against Hambledon in 1769. This was probably the Surrey-based player. In the same season, a player called Wood played for the Duke of Dorset's XI against Wrotham in the minor match that featured John Minshull's century. Given Dorset's strong Kent connection, this was probably John Wood of Kent.

https://en.wikipedia.org/wiki/Gene%20cluster
|
A gene family is a set of homologous genes within one organism. A gene cluster is a group of two or more genes found within an organism's DNA that encode similar polypeptides, or proteins, which collectively share a generalized function and are often located within a few thousand base pairs of each other. The size of gene clusters can vary significantly, from a few genes to several hundred genes. Portions of the DNA sequence of each gene within a gene cluster are found to be identical; however, the resulting protein of each gene is distinctive from the resulting protein of another gene within the cluster. Genes found in a gene cluster may be observed near one another on the same chromosome or on different, but homologous chromosomes. An example of a gene cluster is the Hox gene, which is made up of eight genes and is part of the Homeobox gene family.
Formation
Historically, four models have been proposed for the formation and persistence of gene clusters.
Gene duplication and divergence
This model has been generally accepted since the mid-1970s. It postulates that gene clusters were formed as a result of gene duplication and divergence. These gene clusters include the Hox gene cluster, the human β-globin gene cluster, and four clustered human growth hormone (hGH)/chorionic somatomammotropin genes.
Conserved gene clusters, such as Hox and the human β-globin gene cluster, may be formed as a result of the process of gene duplication and divergence. A gene is duplicated durin

https://en.wikipedia.org/wiki/Prior%20knowledge%20for%20pattern%20recognition
|
Pattern recognition is a very active field of research intimately bound to machine learning. Also known as classification or statistical classification, pattern recognition aims at building a classifier that can determine the class of an input pattern. This procedure, known as training, corresponds to learning an unknown decision function based only on a set of input-output pairs that form the training data (or training set). Nonetheless, in real world applications such as character recognition, a certain amount of information on the problem is usually known beforehand. The incorporation of this prior knowledge into the training is the key element that will allow an increase of performance in many applications.
Prior Knowledge
Prior knowledge refers to all information about the problem available in addition to the training data. However, in this most general form, determining a model from a finite set of samples without prior knowledge is an ill-posed problem, in the sense that a unique model may not exist. Many classifiers incorporate the general smoothness assumption that a test pattern similar to one of the training samples tends to be assigned to the same class.
The importance of prior knowledge in machine learning is suggested by its role in search and optimization. Loosely, the no free lunch theorem states that all search algorithms have the same average performance over all problems, and thus implies that to gain in performance on a certain application one must us

https://en.wikipedia.org/wiki/Ap180
|
AP180 is a protein that plays an important role in clathrin-mediated endocytosis of synaptic vesicles. It is capable of simultaneously binding both membrane lipids (via an ANTH domain) and clathrin and is therefore thought to recruit clathrin to the membrane of newly invaginating vesicles. In Drosophila melanogaster (fruit flies), deletion of the AP180 homologue, leads to enlarged but much fewer vesicles and an overall decrease in transmitter release. In D. melanogaster it was also shown that AP180 is also required for either recycling vesicle proteins and/or maintaining the distribution of both vesicle and synaptic proteins in the nerve terminal. A ubiquitous form of the protein in mammals, CALM, (Clathrin-assembly lymphoid myeloid leukaemia protein) is named after its association with myeloid and lymphoid leukemias where some translocations map to this gene. The C-terminus of AP180 is a powerful and specific inhibitor of clathrin-mediated endocytosis.

|
The Goldman–Hodgkin–Katz flux equation (or GHK flux equation or GHK current density equation) describes the ionic flux across a cell membrane as a function of the transmembrane potential and the concentrations of the ion inside and outside of the cell. Since both the voltage and the concentration gradients influence the movement of ions, this process is a simplified version of electrodiffusion. Electrodiffusion is most accurately defined by the Nernst–Planck equation and the GHK flux equation is a solution to the Nernst–Planck equation with the assumptions listed below.
Origin
The American David E. Goldman of Columbia University, and the English Nobel laureates Alan Lloyd Hodgkin and Bernard Katz derived this equation.
Assumptions
Several assumptions are made in deriving the GHK flux equation (Hille 2001, p. 445) :
The membrane is a homogeneous substance
The electrical field is constant so that the transmembrane potential varies linearly across the membrane
The ions access the membrane instantaneously from the intra- and extracellular solutions
The permeant ions do not interact
The movement of ions is affected by both concentration and voltage differences

|
The Crystal Palace and South London Junction Railway (CPSLJR) was built by the London, Chatham and Dover Railway (LCDR) from to Crystal Palace High Level to serve the Crystal Palace after the building was moved to the area that became known as Crystal Palace (otherwise "Upper Norwood") from its original site in Hyde Park.
History
Origins
The Great Exhibition closed in 1851, leaving the Crystal Palace building in Hyde Park redundant. Rather than simply being demolished, between 1852 and 1854 it was rebuilt in a pleasure park at Sydenham Hill as an "events" venue, creating a potential demand for lucrative leisure travel.
The London Brighton and South Coast Railway (LBSCR) was the first to exploit this by running a spur up from Sydenham to a new station next to the park, opening in 1854. In 1856 the West End of London and Crystal Palace Railway (WELCPR) arrived with a line through its own platforms next to the LBSCR station, and on to . In 1858 this was extended east via to "Bromley" () on the LCDR mainline, and in 1860 west to Victoria.
The WELCPR thus became the LCDR's principal route to central London, and provided good access to the new Crystal Palace site. But it was operated by, and later leased to, the LBSCR, which inevitably led to operational friction. The LCDR needed an independent mainline to the West End and City, and its own Crystal Palace station. In 1863 it opened the new mainline from Beckenham Junction to Victoria via Brixton, with a branch to the Ci

Darren Shan
Darren Shan is the main character of his diary, which is expressed from his point of view. As explained in the last book, "Sons of Destiny", the diary was supposedly transferred from Mr. Tall to the author.
In the first book, Cirque Du Freak/Cirque Du Freak: A Living Nightmare, "Darren" says he used no real names in the books. These are just the names used by him in substitution of the real names of the key players in his life (he does this for their protection and in fear of being discovered for his true self).
Darren became enamored with Larten Crepsley's spider Madam Octa when he went to the Cirque du Freak, where he also learned vampires were real, Mr. Crepsley was one, and his best friend Steve Leonard wanted to become one. However, when Steve was bitten by Madam Octa, Darren was forced to seek the help of Mr. Crepsley, who agreed on the condition that Darren become his vampire assistant instead.

https://en.wikipedia.org/wiki/Cyclol
|
The cyclol hypothesis is the now discredited first structural model of a folded, globular protein, formulated in the 1930s. It was based on the cyclol reaction of peptide bonds proposed by physicist Frederick Frank in 1936, in which two peptide groups are chemically crosslinked. These crosslinks are covalent analogs of the non-covalent hydrogen bonds between peptide groups and have been observed in rare cases, such as the ergopeptides.
Based on this reaction, mathematician Dorothy Wrinch hypothesized in a series of five papers in the late 1930s a structural model of globular proteins. She postulated that, under some conditions, amino acids will spontaneously make the maximum possible number of cyclol crosslinks, resulting in cyclol molecules and cyclol fabrics. She further proposed that globular proteins have a tertiary structure corresponding to Platonic solids and semiregular polyhedra formed of cyclol fabrics with no free edges. In contrast to the cyclol reaction itself, these hypothetical molecules, fabrics and polyhedra have not been observed experimentally. The model has several consequences that render it energetically implausible, such as steric clashes between the protein sidechains. In response to such criticisms J. D. Bernal proposed that hydrophobic interactions are chiefly responsible for protein folding, which was indeed borne out.
Historical context
By the mid-1930s, analytical ultracentrifugation studies by Theodor Svedberg had shown that proteins

https://en.wikipedia.org/wiki/EF-Tu
|
EF-Tu (elongation factor thermo unstable) is a prokaryotic elongation factor responsible for catalyzing the binding of an aminoacyl-tRNA (aa-tRNA) to the ribosome. It is a G-protein, and facilitates the selection and binding of an aa-tRNA to the A-site of the ribosome. As a reflection of its crucial role in translation, EF-Tu is one of the most abundant and highly conserved proteins in prokaryotes. It is found in eukaryotic mitochondria as TUFM.
As a family of elongation factors, EF-Tu also includes its eukaryotic and archaeal homolog, the alpha subunit of eEF-1 (EF-1A).
Background
Elongation factors are part of the mechanism that synthesizes new proteins through translation in the ribosome. Transfer RNAs (tRNAs) carry the individual amino acids that become integrated into a protein sequence, and have an anticodon for the specific amino acid that they are charged with. Messenger RNA (mRNA) carries the genetic information that encodes the primary structure of a protein, and contains codons that code for each amino acid. The ribosome creates the protein chain by following the mRNA code and integrating the amino acid of an aminoacyl-tRNA (also known as a charged tRNA) to the growing polypeptide chain.
There are three sites on the ribosome for tRNA binding. These are the aminoacyl/acceptor site (abbreviated A), the peptidyl site (abbreviated P), and the exit site (abbreviated E). The P-site holds the tRNA connected to the polypeptide chain being synthesized, and the A

https://en.wikipedia.org/wiki/Bootstrapping%20%28statistics%29
|
Bootstrapping is any test or metric that uses random sampling with replacement (e.g. mimicking the sampling process), and falls under the broader class of resampling methods. Bootstrapping assigns measures of accuracy (bias, variance, confidence intervals, prediction error, etc.) to sample estimates. This technique allows estimation of the sampling distribution of almost any statistic using random sampling methods.
Bootstrapping estimates the properties of an estimand (such as its variance) by measuring those properties when sampling from an approximating distribution. One standard choice for an approximating distribution is the empirical distribution function of the observed data. In the case where a set of observations can be assumed to be from an independent and identically distributed population, this can be implemented by constructing a number of resamples with replacement, of the observed data set (and of equal size to the observed data set).
It may also be used for constructing hypothesis tests. It is often used as an alternative to statistical inference based on the assumption of a parametric model when that assumption is in doubt, or where parametric inference is impossible or requires complicated formulas for the calculation of standard errors.
History
The bootstrap was published by Bradley Efron in "Bootstrap methods: another look at the jackknife" (1979), inspired by earlier work on the jackknife. Improved estimates of the variance were developed later. A Ba

https://en.wikipedia.org/wiki/Separable%20partial%20differential%20equation
|
A separable partial differential equation is one that can be broken into a set of separate equations of lower dimensionality (fewer independent variables) by a method of separation of variables. This generally relies upon the problem having some special form or symmetry. In this way, the partial differential equation (PDE) can be solved by solving a set of simpler PDEs, or even ordinary differential equations (ODEs) if the problem can be broken down into one-dimensional equations.
The most common form of separation of variables is simple separation of variables in which a solution is obtained by assuming a solution of the form given by a product of functions of each individual coordinate. There is a special form of separation of variables called -separation of variables which is accomplished by writing the solution as a particular fixed function of the coordinates multiplied by a product of functions of each individual coordinate. Laplace's equation on is an example of a partial differential equation which admits solutions through -separation of variables; in the three-dimensional case this uses 6-sphere coordinates.
(This should not be confused with the case of a separable ODE, which refers to a somewhat different class of problems that can be broken into a pair of integrals; see separation of variables.)

|
Bruton's tyrosine kinase (abbreviated Btk or BTK), also known as tyrosine-protein kinase BTK, is a tyrosine kinase that is encoded by the BTK gene in humans. BTK plays a crucial role in B cell development.
Structure
BTK contains five different protein interaction domains. These domains include an amino terminal pleckstrin homology (PH) domain, a proline-rich TEC homology (TH) domain, SRC homology (SH) domains SH2 and SH3, as well as a kinase domain with enzymatic activity.
Function
BTK plays a crucial role in B cell development as it is required for transmitting signals from the pre-B cell receptor that forms after successful immunoglobulin heavy chain rearrangement. It also has a role in mast cell activation through the high-affinity IgE receptor.
Btk contains a PH domain that binds phosphatidylinositol (3,4,5)-trisphosphate (PIP3). PIP3 binding induces Btk to phosphorylate phospholipase C, which in turn hydrolyzes PIP2, a phosphatidylinositol, into two second messengers, inositol triphosphate (IP3) and diacylglycerol (DAG), which then go on to modulate the activity of downstream proteins during B-cell signalling.
Clinical significance
Mutations in the BTK gene are implicated in the primary immunodeficiency disease X-linked agammaglobulinemia (Bruton's agammaglobulinemia); sometimes abbreviated to XLA and selective IgM deficiency. Patients with XLA have normal pre-B cell populations in their bone marrow but these cells fail to mature and enter the circulation. The

https://en.wikipedia.org/wiki/Dilution%20cloning
|
Dilution cloning or cloning by limiting dilution describes a procedure to obtain a monoclonal cell population starting from a polyclonal mass of cells.
This is achieved by setting up a series of increasing dilutions of the parent (polyclonal) cell culture. A suspension of the parent cells is made. Appropriate dilutions are then made, depending on cell number in the starting population, as well as the viability and characteristics of the cells being cloned.
After the final dilutions are produced, aliquots of the suspension are plated or placed in wells and incubated. If all works correctly, a monoclonal cell colony will be produced. Applications for the procedure include cloning of parasites, T cells, transgenic cells, and macrophages.

https://en.wikipedia.org/wiki/Hyper-IgM%20syndrome%20type%205
|
The fifth type of hyper-IgM syndrome has been characterized in three patients from France and Japan. The symptoms are similar to hyper IgM syndrome type 2, but the AICDA gene is intact.
These three patients instead had mutations in the catalytic domain of uracil-DNA glycosylase, an enzyme that removes uracil from DNA. In hyper-IgM syndromes, patients are deficient in the immunoglobulins, IgG, IgE and IgA types since the antibody producing B cells can not carry out the gene recombination steps necessary to class switch from immunoglobulin M (IgM) to the other three immunoglobulins types.
Hyper IgM syndromes
Hyper IgM syndromes is a group of primary immune deficiency disorders characterized by defective CD40 signaling; via B cells affecting class switch recombination (CSR) and somatic hypermutation. Immunoglobulin (Ig) class switch recombination deficiencies are characterized by elevated serum IgM levels and a considerable deficiency in Immunoglobulins G (IgG), A (IgA) and E (IgE). As a consequence, people with HIGM have an increased susceptibility to infections.
Signs and symptoms
Hyper IgM syndrome can have the following syndromes:
Infection/Pneumocystis pneumonia (PCP), which is common in infants with hyper IgM syndrome, is a serious illness. PCP is one of the most frequent and severe opportunistic infections in people with weakened immune systems.

https://en.wikipedia.org/wiki/Vertex%20normal
|
In the geometry of computer graphics, a vertex normal at a vertex of a polyhedron is a directional vector associated with a vertex, intended as a replacement to the true geometric normal of the surface. Commonly, it is computed as the normalized average of the surface normals of the faces that contain that vertex. The average can be weighted for example by the area of the face or it can be unweighted. Vertex normals can also be computed for polygonal approximations to surfaces such as NURBS, or specified explicitly for artistic purposes. Vertex normals are used in Gouraud shading, Phong shading and other lighting models. Using vertex normals, much smoother shading than flat shading can be achieved; however, without some modifications to topology such a support loops, it cannot produce a sharper edge.

https://en.wikipedia.org/wiki/Hymenophyllaceae
|
The Hymenophyllaceae, the filmy ferns and bristle ferns, are a family of two to nine genera (depending on classification system) and about 650 known species of ferns, with a subcosmopolitan distribution, but generally restricted to very damp places or to locations where they are wetted by spray from waterfalls or springs. A recent fossil find shows that ferns of Hymenophyllaceae have existed since at least the Upper Triassic.
Description
They often appear as very dark green or even black clumps and may be mistaken for a robust moss or liverwort. The rhizome is usually thin and wiry and the fronds variously pinnate with a single strand ("nerve") of vascular tissue. As in most ferns, young fronds have circinate vernation. In most species, the frond, apart from the vascular tissue, is only a single cell thick, and they do not have any stomata. The cuticle is also greatly reduced or absent, leaving filmy ferns very susceptible to desiccation where a reliable water supply is not present. The leaves occasionally bear hairs, but scales are generally not present. The sori are borne at the leaf margins at the end of the nerve. They are protected by conical, bivalvate, or tubular indusia. Within the sori, sporangia mature starting at the apex of the sorus and progressing to the base. They have a continuous, oblique annulus and release round, green trilete spores. The spores grow into thread- or ribbon-like gametophytes; in many species, the gametophyte has an extended, independent lif

https://en.wikipedia.org/wiki/Diosgenin
|
Diosgenin, a phytosteroid sapogenin, is the product of hydrolysis by acids, strong bases, or enzymes of saponins, extracted from the tubers of Dioscorea wild yam species, such as the Kokoro. The sugar-free (aglycone) product of such hydrolysis, diosgenin is used for the commercial synthesis of cortisone, pregnenolone, progesterone, and other steroid products.
Sources
It is present in detectable amounts in Costus speciosus, Smilax menispermoidea, Helicteres isora, species of Paris, Aletris, Trigonella, and Trillium, and in extractable amounts from many species of Dioscorea – D. althaeoides, D. colletti, D. composita, D. floribunda, D. futschauensis, D. gracillima, D. hispida, D. hypoglauca, D. mexicana, D. nipponica, D. panthaica, D. parviflora, D. septemloba, and D. zingiberensis.
Industrial uses
Diosgenin is a chemical precursor for several hormones, starting with the Marker degradation process, which includes synthesis of progesterone. The process was used in the early manufacturing of combined oral contraceptive pills. Diosgenin in dietary supplements is not a physiological precursor to estradiol or progesterone, and the use of such products as wild yam has no hormonal activity in the human body.
