|
pisg, short for Perl IRC Statistics Generator is a popular open-source Internet Relay Chat (IRC) log file analysis and statistical visualization program. It is written in perl by Morten Brix Pedersen. It analyzes various formats of log files from IRC clients and bots and generates HTML pages containing statistics about the channel the logs were taken from. It is often considered a competitor to mIRCStats, a similar shareware program.
pisg supports many log formats, including: mIRC, Trillian, Eggdrop, irssi, and more, and can be customized to work with other log file formats. Because it is open-source, pisg has an active community for further developing log interpreters. pisg runs on basically any platform with perl, including Linux, BSD, Microsoft Windows and Mac OS X.

https://en.wikipedia.org/wiki/Bernard%E2%80%93Soulier%20syndrome
|
Bernard–Soulier syndrome (BSS) is a rare autosomal recessive bleeding disorder that is caused by a deficiency of the glycoprotein Ib-IX-V complex (GPIb-IX-V), the receptor for von Willebrand factor. The incidence of BSS is estimated to be less than 1 case per million persons, based on cases reported from Europe, North America, and Japan. BSS is a giant platelet disorder, meaning that it is characterized by abnormally large platelets.
Signs and symptoms
Bernard–Soulier syndrome often presents as a bleeding disorder with symptoms of:
Genetics
In regards to mechanism, there are three genes: GP1BA, GP1BB and GP9 that are involved (due to mutations). These mutations do not allow the GPIb-IX-V complex to bind to the von Willebrand factor, which in turn is what would help platelets adhere to a site of injury which eventually helps stop bleeding.
Diagnosis
In terms of diagnosis Bernard–Soulier syndrome is characterized by prolonged bleeding time, thrombocytopenia, increased megakaryocytes, and enlarged platelets, Bernard–Soulier syndrome is associated with quantitative or qualitative defects of the platelet glycoprotein complex GPIb/V/IX. The degree of thrombocytopenia may be estimated incorrectly, due to the possibility that when the platelet count is performed with automatic counters, giant platelets may reach the size of red blood cells. The large platelets and low platelet count in BSS are seemingly due to the absence of GPIbα and the filamin A binding site that links the GPI

https://en.wikipedia.org/wiki/Binomial%20proportion%20confidence%20interval
|
In statistics, a binomial proportion confidence interval is a confidence interval for the probability of success calculated from the outcome of a series of success–failure experiments (Bernoulli trials). In other words, a binomial proportion confidence interval is an interval estimate of a success probability p when only the number of experiments n and the number of successes nS are known.
There are several formulas for a binomial confidence interval, but all of them rely on the assumption of a binomial distribution. In general, a binomial distribution applies when an experiment is repeated a fixed number of times, each trial of the experiment has two possible outcomes (success and failure), the probability of success is the same for each trial, and the trials are statistically independent. Because the binomial distribution is a discrete probability distribution (i.e., not continuous) and difficult to calculate for large numbers of trials, a variety of approximations are used to calculate this confidence interval, all with their own tradeoffs in accuracy and computational intensity.
A simple example of a binomial distribution is the set of various possible outcomes, and their probabilities, for the number of heads observed when a coin is flipped ten times. The observed binomial proportion is the fraction of the flips that turn out to be heads. Given this observed proportion, the confidence interval for the true probability of the coin landing on heads is a range of possibl

https://en.wikipedia.org/wiki/SOS%20box
|
SOS box is the region in the promoter of various genes to which the LexA repressor binds to repress the transcription of SOS-induced proteins. This occurs in the absence of DNA damage. In the presence of DNA damage the binding of LexA is inactivated by the RecA activator. SOS boxes differ in DNA sequences and binding affinity towards LexA from organism to organism. Furthermore, SOS boxes may be present in a dual fashion, which indicates that more than one SOS box can be within the same promoter.

https://en.wikipedia.org/wiki/Hexagonal%20chess
|
Hexagonal chess is a group of chess variants played on boards composed of hexagon . The best known is Gliński's variant, played on a symmetric 91-cell hexagonal board.
Since each hexagonal cell not on a board edge has six neighbor cells, there is generally increased mobility for pieces compared to a standard orthogonal chessboard. For example, a rook usually has six natural directions for movement instead of four. Three colours are typically used so that no two neighboring cells are the same colour, and a colour-restricted game piece such as the orthodox chess bishop usually comes in sets of three per player in order to maintain the game's balance.
Many different shapes and sizes of hexagon-based boards are used by variants. The nature of the game is also affected by the 30° orientation of the board's cells; the board can be horizontally oriented (Wellisch's, de Vasa's, Brusky's) or vertically oriented (Gliński's, Shafran's, McCooey's). When the sides of hexagonal cells face the players, pawns typically have one straightforward move direction. If a variant's gameboard has cell vertices facing the players, pawns typically have two oblique-forward move directions. The possibility of a hexagon-based board with three-fold rotational symmetry has also resulted in a number of three-player variants.
Because the six edges and six vertices of regular hexagons are equally spaced, directions can be referenced analogously to the 12 cardinal directions of a clock face. For example, on

https://en.wikipedia.org/wiki/Spacer%20DNA
|
Spacer DNA is a region of non-coding DNA between genes. The terms intergenic spacer (IGS) or non-transcribed spacer (NTS) are used particularly for the spacer DNA between the many tandemly repeated copies of the ribosomal RNA genes.
In bacteria, spacer DNA sequences are only a few nucleotides long. In eukaryotes, they can be extensive and include repetitive DNA, comprising the majority of the DNA of the genome. In ribosomal DNA, there are spacers within and between gene clusters, called internal transcribed spacer (ITS) and external transcribed spacers (ETS), respectively. In animals, the mitochondrial DNA genes generally have very short spacers. In fungi, mitochondrial DNA spacers are common and variable in length, and they may also be mobile.
Due to the non-coding nature of spacer DNA, its nucleotide sequence changes much more rapidly over time than nucleotide sequences coding for genes that are subject to selective forces. Although spacer DNA might not have a function that depends on its nucleotide sequence, it may have sequence-independent functions.
Spacer DNA has practical applications that enable researchers and scientists to examine interactions between CRISPR proteins and bacteriophages.

https://en.wikipedia.org/wiki/Blaschko%27s%20lines
|
Blaschko's lines, also called the lines of Blaschko, are lines of normal cell development in the skin. These lines are only visible in those with a mosaic skin condition or in chimeras where different cell lines contain different genes. These lines may express different amounts of melanin, or become visible due to a differing susceptibility to disease. In such individuals, they can become apparent as whorls, patches, streaks or lines in a linear or segmental distribution over the skin. They follow a V shape over the back, S-shaped whirls over the chest and sides, and wavy shapes on the head. Not all mosaic skin conditions follow Blaschko's lines.
The lines are believed to trace the migration of embryonic cells. They do not correspond to nervous, muscular, or lymphatic systems. The lines are not unique to humans and can be observed in other non-human animals with mosaicism.
Alfred Blaschko is credited with the first demonstration of these lines in 1901.
Signs and symptoms
The skin lesions that follow Blaschko's lines are varied. They include genetic, congenital and acquired (i.e., non-genetic) conditions. Examples include:
Pigmentary disorders
Nevus achromicus (including incontinentia pigmenti achromians, also known as hypomelanosis of Ito)
Epidermal nevus
Nevus sebaceus
Inflammatory linear verrucous epidermal nevus
X-linked genetic skin disorder

Oliver Marcell (June 21, 1895 – June 12, 1949), nicknamed "Ghost", was an American third baseman in the Negro leagues for a number of teams around the league from 1918 to 1931. He also played shortstop. A Creole born in Thibodaux, Louisiana, he batted and threw right-handed.
While the Negro leagues had many statistics recorded in the 1920s, Marcell put up outstanding numbers. In 1922 with the Bacharach Giants, he posted a .379 batting average. Again in 1924, he hit well, putting up a .352 average for Bacharach and the New York Lincoln Giants.
Although "Ghost" was a top-class hitting infielder, his defensive skills took center stage by comparison. He was considered by most to be the greatest fielding third basemen in the league throughout the 1920s and possibly of all time. Baseball Hall of Famer Judy Johnson once admitted that Marcell was a better defensive player than himself. During that time, he and shortstop Dick Lundy made up one of the best left-side infields ever.
Marcell was known for a terrible temper, with umpires and opponents commonly drawn into arguments with him, and even teammates sometimes fighting him. There is a story that Marcell once hit Oscar Charleston in the head with a bat. He participated in two Negro World Series, both for the Bacharach Giants. He put up fairly good numbers during one of them (.293, six RBIs in 11 games). In the other, he posted a .235 average with 2 RBIs in 9 games. However, he did much better than that when he got his chance ag

Evans Hall is the statistics, economics, and mathematics building on the campus of the University of California, Berkeley.
Computer History importance
Evans Hall also served as the gateway for the entire west coast's ARPAnet access during the early stages of the Internet's existence; at the time, the backbone was a 56kbit/s line to Chicago.
Because of its proximity to the engineering school, and the location of both the departments of Computer Science, and Mathematics, Evans Hall was the building in which the original vi text editor was programmed, as well as the birthplace of Berkeley Unix (BSD), and Rogue, which was further developed there by Glenn C Wickman, and Michael Toy. Rogue's origins included the curses library, which Rogue was originally written to test. Additionally, both Ingres and Postgres were originally coded in Evans, under Prof. Michael Stonebraker's direction.
The office of Professor Doug Cooper, who wrote the widely used programming textbook "Oh! Pascal!", was in this building.
Architecture
Construction
Evans Hall is situated at the northeast corner of campus, just east of Memorial Glade. It was built in 1971 and is named after Griffith C. Evans, chairman of mathematics from 1934 to 1949 who combined the fields of mathematics and economics. The architect was Gardner Dailey.
In the 1990s, this building saw significant renovation including seismic retrofits and a new paint job. Today, the building sports a blue-green exterior with orange-red accents.

https://en.wikipedia.org/wiki/Activated%20protein%20C%20resistance
|
Activated protein C resistance (APCR) is a hypercoagulability (an increased tendency of the blood to clot) characterized by a lack of a response to activated protein C (APC), which normally helps prevent blood from clotting excessively. This results in an increased risk of venous thrombosis (blood clots in veins), which resulting in medical conditions such as deep vein thrombosis (usually in the leg) and pulmonary embolism (in the lung, which can cause death). The most common cause of hereditary APC resistance is factor V Leiden mutation.
Presentation
Associated conditions
An estimated 64 percent of patients with venous thromboembolism may have APC resistance.
Genetics
The disorder can be acquired or inherited, the hereditary form having an autosomal dominant inheritance pattern.
Pathophysiology
APC (with protein S as a cofactor) degrades Factor Va and Factor VIIIa. APC resistance is the inability of protein C to cleave Factor Va and/or Factor VIIIa, which allows for longer duration of thrombin generation and may lead to a hypercoagulable state. This may be hereditary or acquired. The best known and most common hereditary form is Factor V Leiden, which is responsible for more than 95% of cases. Other genetic causes include Factor V Cambridge (VThr306) and the factor V HR2 haplotype (A4070G mutation). Acquired forms of APC resistance occur in the presence of elevated Factor VIII concentrations. Antiphospholipid antibodies, pregnancy, and certain forms of estrogen therapy,

https://en.wikipedia.org/wiki/Warfarin%20necrosis
|
Warfarin-induced skin necrosis is a condition in which skin and subcutaneous tissue necrosis (tissue death) occurs due to acquired protein C deficiency following treatment with anti-vitamin K anticoagulants (4-hydroxycoumarins, such as warfarin).
Warfarin necrosis is a rare but severe complication of treatment with warfarin or related anticoagulants. The typical patient appears to be an obese, middle aged woman (median age 54 years, male to female ratio 1:3). This drug eruption usually occurs between the third and tenth days of therapy with warfarin derivatives. The first symptoms are pain and redness in the affected area. As they progress, lesions develop a sharp border and become petechial, then hard and purpuric. They may then resolve or progress to form large, irregular, bloody bullae with eventual necrosis and slow-healing eschar formation. Favored sites are breasts, thighs, buttocks and penis, all areas with subcutaneous fat. In rare cases, the fascia and muscle are involved.
Development of the syndrome is associated with the use of large loading doses at the start of treatment.
Mechanism
Warfarin necrosis usually occurs three to five days after drug therapy is begun, and a high initial dose increases the risk of its development. Warfarin-induced necrosis can develop both at sites of local injection and - when infused intravenously - in a widespread pattern.
In warfarin's initial stages of action, inhibition of protein C and Factor VII is stronger than inhibition

https://en.wikipedia.org/wiki/Pipe%20%28fluid%20conveyance%29
|
A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.
In common usage the words pipe and tube are usually interchangeable, but in industry and engineering, the terms are uniquely defined. Depending on the applicable standard to which it is manufactured, pipe is generally specified by a nominal diameter with a constant outside diameter (OD) and a schedule that defines the thickness. Tube is most often specified by the OD and wall thickness, but may be specified by any two of OD, inside diameter (ID), and wall thickness. Pipe is generally manufactured to one of several international and national industrial standards. While similar standards exist for specific industry application tubing, tube is often made to custom sizes and a broader range of diameters and tolerances. Many industrial and government standards exist for the production of pipe and tubing. The term "tube" is also commonly applied to non-cylindrical sections, i.e., square or rectangular tubing. In general, "pipe" is the more common term in most of the world, whereas "tube" is more widely used in the United States.
Both "pipe" and "tube" imply a level of rigidity and permanence, whereas a hose (or hosepipe) is usually portable and

https://en.wikipedia.org/wiki/Snub%2024-cell
|
In geometry, the snub 24-cell or snub disicositetrachoron is a convex uniform 4-polytope composed of 120 regular tetrahedral and 24 icosahedral cells. Five tetrahedra and three icosahedra meet at each vertex. In total it has 480 triangular faces, 432 edges, and 96 vertices. One can build it from the 600-cell by diminishing a select subset of icosahedral pyramids and leaving only their icosahedral bases, thereby removing 480 tetrahedra and replacing them with 24 icosahedra.
Topologically, under its highest symmetry, [3+,4,3], as an alternation of a truncated 24-cell, it contains 24 pyritohedra (an icosahedron with Th symmetry), 24 regular tetrahedra, and 96 triangular pyramids.
Semiregular polytope
It is one of three semiregular 4-polytopes made of two or more cells which are Platonic solids, discovered by Thorold Gosset in his 1900 paper. He called it a tetricosahedric for being made of tetrahedron and icosahedron cells. (The other two are the rectified 5-cell and rectified 600-cell.)

https://en.wikipedia.org/wiki/Bairstow%27s%20method
|
In numerical analysis, Bairstow's method is an efficient algorithm for finding the roots of a real polynomial of arbitrary degree. The algorithm first appeared in the appendix of the 1920 book Applied Aerodynamics by Leonard Bairstow. The algorithm finds the roots in complex conjugate pairs using only real arithmetic.
See root-finding algorithm for other algorithms.
Description of the method
Bairstow's approach is to use Newton's method to adjust the coefficients u and v in the quadratic until its roots are also roots of the polynomial being solved. The roots of the quadratic may then be determined, and the polynomial may be divided by the quadratic to eliminate those roots. This process is then iterated until the polynomial becomes quadratic or linear, and all the roots have been determined.
Long division of the polynomial to be solved

A second division of by is performed to yield a quotient and remainder with

|
Tuberous sclerosis complex (TSC) tumor suppressors form the TSC1-TSC2 molecular complex. Under poor growth conditions the TSC1-TSC2 complex limits cell growth. A key promoter of cell growth, mTORC1, is inhibited by the tuberous sclerosis complex. Insulin activates mTORC1 and causes dissociation of TSC from the surface of lysosomes.
Resistance to ischemia-reperfusion injury by protein restriction is mediated by activation of the tuberous sclerosis complex.

https://en.wikipedia.org/wiki/Wigner%20crystal
|
A Wigner crystal is the solid (crystalline) phase of electrons first predicted by Eugene Wigner in 1934. A gas of electrons moving in a uniform, inert, neutralizing background (i.e. Jellium Model) will crystallize and form a lattice if the electron density is less than a critical value. This is because the potential energy dominates the kinetic energy at low densities, so the detailed spatial arrangement of the electrons becomes important. To minimize the potential energy, the electrons form a bcc (body-centered cubic) lattice in 3D, a triangular lattice in 2D and an evenly spaced lattice in 1D. Most experimentally observed Wigner clusters exist due to the presence of the external confinement, i.e. external potential trap. As a consequence, deviations from the b.c.c or triangular lattice are observed. A crystalline state of the 2D electron gas can also be realized by applying a sufficiently strong magnetic field. However, it is still not clear whether it is the Wigner crystallization that has led to observation of insulating behaviour in magnetotransport measurements on 2D electron systems, since other candidates are present, such as Anderson localization.
More generally, a Wigner crystal phase can also refer to a crystal phase occurring in non-electronic systems at low density. In contrast, most crystals melt as the density is lowered. Examples seen in the laboratory are charged colloids or charged plastic spheres.

|
The Great Temple of the Aten (or the pr-Jtn, House of the Aten) was a temple located in the city of el-Amarna (ancient Akhetaten), Egypt. It served as the main place of worship of the deity Aten during the reign of the 18th Dynasty pharaoh Akhenaten (c. 1353–1336 BCE). Akhenaten ushered in a unique period of ancient Egyptian history by establishing the new religious cult dedicated to the sun-disk Aten, originally an aspect of Ra, the sun god in traditional ancient Egyptian religion. The king shut down traditional worship of other deities like Amun-Ra, and brought in a new era, though short-lived, of seeming monotheism where the Aten was worshipped as a sun god and Akhenaten and his wife, Nefertiti, represented the divinely royal couple that connected the people with the god. Although he began construction at Karnak during his rule, the association the city had with other gods drove Akhenaten to establish a new city and capital at Amarna for the Aten. Akhenaten built the city along the east bank of the Nile River, setting up workshops, palaces, suburbs and temples. The Great Temple of the Aten was located just north of the Central City and, as the largest temple dedicated to the Aten, was where Akhenaten fully established the proper cult and worship of the sun-disk.
Construction
The city of Akhetaten was built rather hastily and was constructed mostly of mud-brick. Mud-bricks were made by drying in the sun and they measured 33–37 cm x 15–16 cm x 9–10 cm, although bricks for

|
Owen Brannigan OBE (10 March 19089 May 1973) was an English bass, known in opera for buffo roles and in concert for a wide range of solo parts in music ranging from Henry Purcell to Michael Tippett. He is best remembered for his roles in Mozart and Britten operas and for his recordings of roles in Britten, Offenbach and Gilbert and Sullivan operas, as well as recordings of English folk songs.
Brannigan began as an amateur singer and attended music college part-time, while working as a joiner, until his quality was recognised and he was awarded a scholarship during World War II. Although he had an international opera career, he performed most frequently with English opera companies, particularly Sadler's Wells opera, and later at Glyndebourne and Covent Garden. Highlights of his broad repertory included creating three roles in Benjamin Britten's early operas, and two more in later Britten operas that were written specifically for him. On record and in concert at the Proms he was a popular interpreter of the bass-baritone roles in Gilbert and Sullivan operas. Brannigan's oratorio and concert repertory was extensive, covering works from many periods.
Biography
Early years
Brannigan was born in Annitsford, North Tyneside, near Newcastle, the son of the local church organist (of Irish descent), in whose choir he sang as a boy. In 1929, he moved south to look for work. He worked as a joiner in Slough, and in his spare time he appeared with the Windsor Operatic Society. In 1

A theoretical motivation for general relativity, including the motivation for the geodesic equation and the Einstein field equation, can be obtained from special relativity by examining the dynamics of particles in circular orbits about the Earth. A key advantage in examining circular orbits is that it is possible to know the solution of the Einstein Field Equation a priori. This provides a means to inform and verify the formalism.
General relativity addresses two questions:
How does the curvature of spacetime affect the motion of matter?
How does the presence of matter affect the curvature of spacetime?
The former question is answered with the geodesic equation. The second question is answered with the Einstein field equation. The geodesic equation and the field equation are related through a principle of least action. The motivation for the geodesic equation is provided in the section Geodesic equation for circular orbits. The motivation for the Einstein field equation is provided in the section Stress–energy tensor.
Geodesic equation for circular orbits
Kinetics of circular orbits
For definiteness consider a circular Earth orbit (helical world line) of a particle. The particle travels with speed v. An observer on Earth sees that length is contracted in the frame of the particle. A measuring stick traveling with the particle appears shorter to the Earth observer. Therefore, the circumference of the orbit, which is in the direction of motion appears longer than tim

https://en.wikipedia.org/wiki/Cysteine%20protease
|
Cysteine proteases, also known as thiol proteases, are hydrolase enzymes that degrade proteins. These proteases share a common catalytic mechanism that involves a nucleophilic cysteine thiol in a catalytic triad or dyad.
Discovered by Gopal Chunder Roy in 1873, the first cysteine protease to be isolated and characterized was papain, obtained from Carica papaya. Cysteine proteases are commonly encountered in fruits including the papaya, pineapple, fig and kiwifruit. The proportion of protease tends to be higher when the fruit is unripe. In fact, the latex of dozens of different plant families are known to contain cysteine proteases. Cysteine proteases are used as an ingredient in meat tenderizers.
Classification
The MEROPS protease classification system counts 14 superfamilies plus several currently unassigned families (as of 2013) each containing many families. Each superfamily uses the catalytic triad or dyad in a different protein fold and so represent convergent evolution of the catalytic mechanism.
For superfamilies, P indicates a superfamily containing a mixture of nucleophile class families, and C indicates purely cysteine proteases. superfamily. Within each superfamily, families are designated by their catalytic nucleophile (C denoting cysteine proteases).

https://en.wikipedia.org/wiki/Dom%C5%BEale%20radio%20transmitter
|
The Domžale radio transmitter is a facility for medium wave broadcasting in Domžale, in Slovenia. The transmitter is fully transistorized. It could be received easily at a medium wave frequency of 918 kHz across the whole of Europe at night-time. It was the strongest radio transmitter of the Republic of Slovenia, broadcasting the first national radio channel.
History
The first transmitter was built in 1927 and started operation in September 1928 with the transmission from a fair in Ljubljana, and later a solemn broadcast of Franc Finžgar talking about Slovene language and Oton Župančič reading verses from his poem Duma. The transmitter had the power of 2.5 kilowatts, upgraded in 1932 to 5 kW and in 1939 to over 100 kW. A t-antenna with 5 wires, it was hung on two 120-metre tall steel framework masts, which were insulated against the ground. It was destroyed by German airplanes on 11 April 1941, during the invasion of Yugoslavia in World War II.
In 1949, the reconstruction of the transmitter started under the new socialist government. The transmitter was equipped with a 60-metre tall guyed tube mast, which was insulated against the ground. It entered service on 25 March 1951. This radio mast was replaced a little later by a 136-metre high guyed steel framework mast, which was also insulated against the ground.
In 1969, the transmitting power was increased to 200 kilowatts. In the course of the roll-out of the Geneva wave plan the transmitter got the licence to work with an

Sredna Gora is 285 km long, reaching 50 km at its greatest width. Its highest peak is Golyam Bogdan at .
The mountain is divided into three parts by the rivers Topolnitsa and Stryama — a western (Ihtimanska Sredna Gora), a central (Sashtinska Sredna Gora) and an eastern part (Sarnena Gora).
Geography
Location and limits
Sredna Gora is situated in central Bulgaria, south of and parallel to the Balkan Mountains and north of the Upper Thracian Plain. It extends from the river Iskar in the west to the elbow of the river Tundzha north of the city of Yambol in the east. The main orographic ridge extends from west to east, where the mountain range reaches a total length of 285 km; its maximum width from north to south is 50 km.

https://en.wikipedia.org/wiki/Nijmegen%20breakage%20syndrome
|
Nijmegen breakage syndrome (NBS) is a rare autosomal recessive congenital disorder causing chromosomal instability, probably as a result of a defect in the double Holliday junction DNA repair mechanism and/or the synthesis dependent strand annealing mechanism for repairing double strand breaks in DNA (see Homologous recombination).
NBS1 codes for a protein (nibrin) that has two major functions: (1) to stop the cell cycle in the S phase, when there are errors in the cell DNA (2) to interact with FANCD2 that can activate the BRCA1/BRCA2 pathway of DNA repair. This explains why mutations in the NBS1 gene lead to higher levels of cancer (see Fanconi anemia, Cockayne syndrome.)
The name derives from the Dutch city Nijmegen, where the condition was first described.
Most people with NBS have West Slavic origins. The largest number of them live in Poland.
Presentation
It is characterized by microcephaly, a distinct facial appearance, short stature, immunodeficiency, radiation sensitivity and a strong predisposition to lymphoid malignancy. NBS is caused by a mutation in the NBS1 gene. Unsurprisingly, many of the features are similar to ataxia telangiectasia (AT) and this syndrome was sometimes termed AT-variant 1, as the protein mutated in AT, ATM, interacts with the MRE11/RAD50/NBS1 (MRN) complex. Other syndromes with clinical features similar to Nijmegen Breakage Syndrome include RAD50 deficiency and Cernunnos/NHEJ deficiency.
Cause
NBS is caused by a mutation in the NBS1

https://en.wikipedia.org/wiki/CJKR-FM
|
CJKR-FM is a Canadian radio station broadcasting on the assigned frequency of 97.5 MHz in Winnipeg, Manitoba. It airs an active rock format with the on-air brand name Power 97. The station is owned and operated by Corus Entertainment, which also owns sister stations CJOB and CFPG-FM. The studios and offices are located at 201 Portage Avenue in downtown Winnipeg, while its transmitter is located on Brady Road in south Winnipeg.
CJKR was formerly the most powerful FM radio station in Canada, operating with 310,000 watts. Most FM stations in Canada and the United States run 100,000 watts or less. Because CJKR-FM is one of the oldest FM stations in Canada, it was grandfathered with a much higher power. (In Winnipeg, CBW-FM also operates with an unusually high power, 160,000 watts). Following a fire to its transmitter in 2021, the station has been operating on reduced power, with plans to install a new HD Radio antenna operating at 93,900 watts. Power 97 is simulcast on Shaw Direct channel 860.
History
The station first signed on the air on May 27, 1948 as CJOB-FM, an FM simulcast of CJOB. The station applied to the Board of Broadcast Governors (BBG) to move its broadcast frequency from 103.1 MHz to the current 97.5 MHz. It began airing distinct programming in 1962, featured a country format as CHMM-FM in the late 1970s and early 1980s, and then changed its format to soft rock and its call sign to CKIS-FM in 1984. In the late 1980s, CKIS moved to a rock format, which was not in

https://en.wikipedia.org/wiki/Schoof%E2%80%93Elkies%E2%80%93Atkin%20algorithm
|
The Schoof–Elkies–Atkin algorithm (SEA) is an algorithm used for finding the order of or calculating the number of points on an elliptic curve over a finite field. Its primary application is in elliptic curve cryptography. The algorithm is an extension of Schoof's algorithm by Noam Elkies and A. O. L. Atkin to significantly improve its efficiency (under heuristic assumptions).
Details
The Elkies-Atkin extension to Schoof's algorithm works by restricting the set of primes considered to primes of a certain kind. These came to be called Elkies primes and Atkin primes respectively. A prime is called an Elkies prime if the characteristic equation: splits over , while an Atkin prime is a prime that is not an Elkies prime. Atkin showed how to combine information obtained from the Atkin primes with the information obtained from Elkies primes to produce an efficient algorithm, which came to be known as the Schoof–Elkies–Atkin algorithm. The first problem to address is to determine whether a given prime is Elkies or Atkin. In order to do so, we make use of modular polynomials that parametrize pairs of -isogenous elliptic curves in terms of their j-invariants (in practice alternative modular polynomials may also be used but for the same purpose).
If the instantiated polynomial has a root in then is an Elkies prime, and we may compute a polynomial whose roots correspond to points in the kernel of the -isogeny from to . The polynomial is a divisor of the corresponding divisi

https://en.wikipedia.org/wiki/Back%20pressure
|
Back pressure (or backpressure) is the term for a resistance to the desired flow of fluid through pipes. Obstructions or tight bends create backpressure via friction loss and pressure drop.
Explanation
A common example of backpressure is that caused by the exhaust system (consisting of the exhaust manifold, catalytic converter, muffler and connecting pipes) of an automotive four-stroke engine, which has a negative effect on engine efficiency, resulting in a decrease of power output that must be compensated by increasing fuel consumption.
In a piston-ported two-stroke engine, however, the situation is more complicated, due to the need to prevent unburned fuel/air mixture from passing right through the cylinders into the exhaust. During the exhaust phase of the cycle, backpressure is even more undesirable than in a four-stroke engine, as there is less time available for exhaust and the lack of pumping action from the piston to force the exhaust out of the cylinder. However, since the exhaust port necessarily remains open for a time after scavenging is completed, unburned mixture can follow the exhaust out of the cylinder, wasting fuel and increasing pollution. This can only be prevented if the pressure at the exhaust port is greater than that in the cylinder. Since the timing of this process is determined mainly by exhaust system geometry, which is extremely difficult to make variable, correct timing and therefore optimum engine efficiency can typically only be achieved ove

In physics, the Yang–Baxter equation (or star–triangle relation) is a consistency equation which was first introduced in the field of statistical mechanics. It depends on the idea that in some scattering situations, particles may preserve their momentum while changing their quantum internal states. It states that a matrix , acting on two out of three objects, satisfies
In one-dimensional quantum systems, is the scattering matrix and if it satisfies the Yang–Baxter equation then the system is integrable. The Yang–Baxter equation also shows up when discussing knot theory and the braid groups where corresponds to swapping two strands. Since one can swap three strands two different ways, the Yang–Baxter equation enforces that both paths are the same.
It takes its name from independent work of C. N. Yang from 1968, and R. J. Baxter from 1971.

https://en.wikipedia.org/wiki/Electrodialysis
|
Electrodialysis (ED) is used to transport salt ions from one solution through ion-exchange membranes to another solution under the influence of an applied electric potential difference. This is done in a configuration called an electrodialysis cell. The cell consists of a feed (dilute) compartment and a concentrate (brine) compartment formed by an anion exchange membrane and a cation exchange membrane placed between two electrodes. In almost all practical electrodialysis processes, multiple electrodialysis cells are arranged into a configuration called an electrodialysis stack, with alternating anion and cation-exchange membranes forming the multiple electrodialysis cells. Electrodialysis processes are different from distillation techniques and other membrane based processes (such as reverse osmosis (RO)) in that dissolved species are moved away from the feed stream, whereas other processes move away the water from the remaining substances. Because the quantity of dissolved species in the feed stream is far less than that of the fluid, electrodialysis offers the practical advantage of much higher feed recovery in many applications.
Method
In an electrodialysis stack, the dilute (D) feed stream, brine or concentrate (C) stream, and electrode (E) stream are allowed to flow through the appropriate cell compartments formed by the ion-exchange membranes. Under the influence of an electrical potential difference, the negatively charged ions (e.g., chloride) in the dilute stream m

https://en.wikipedia.org/wiki/Rotational%E2%80%93vibrational%20coupling
|
In physics, rotational–vibrational coupling occurs when the rotation frequency of a system is close to or identical to a natural internal vibration frequency. The animation on the right shows ideal motion, with the force exerted by the spring and the distance from the center of rotation increasing together linearly with no friction.
In rotational-vibrational coupling, angular velocity oscillates. By pulling the circling masses closer together, the spring transfers its stored strain energy into the kinetic energy of the circling masses, increasing their angular velocity. The spring cannot bring the circling masses together, since the spring's pull weakens as the circling masses approach. At some point, the increasing angular velocity of the circling masses overcomes the pull of the spring, causing the circling masses to increasingly distance themselves. This increasingly strains the spring, strengthening its pull and causing the circling masses to transfer their kinetic energy into the spring's strain energy, thereby decreasing the circling masses' angular velocity. At some point, the pull of the spring overcomes the angular velocity of the circling masses, restarting the cycle.
In helicopter design, helicopters must incorporate damping devices, because at specific angular velocities, the rotorblade vibrations can reinforced themselves by rotational-vibrational coupling, and build up catastrophically. Without damping, these vibrations would cause the rotorblades to break loo

https://en.wikipedia.org/wiki/Tobit%20model
|
In statistics, a tobit model is any of a class of regression models in which the observed range of the dependent variable is censored in some way. The term was coined by Arthur Goldberger in reference to James Tobin, who developed the model in 1958 to mitigate the problem of zero-inflated data for observations of household expenditure on durable goods. Because Tobin's method can be easily extended to handle truncated and other non-randomly selected samples, some authors adopt a broader definition of the tobit model that includes these cases.
Tobin's idea was to modify the likelihood function so that it reflects the unequal sampling probability for each observation depending on whether the latent dependent variable fell above or below the determined threshold. For a sample that, as in Tobin's original case, was censored from below at zero, the sampling probability for each non-limit observation is simply the height of the appropriate density function. For any limit observation, it is the cumulative distribution, i.e. the integral below zero of the appropriate density function. The tobit likelihood function is thus a mixture of densities and cumulative distribution functions.

Below are the likelihood and log likelihood functions for a type I tobit. This is a tobit that is censored from below at when the latent variable . In writing out the likelihood function, we first define an indicator function :

George Ebialimolisa Ndah (born 23 December 1974) is an English-born Nigerian former professional footballer who played as a striker from 1992 until 2006.
He played in the Premier League for Crystal Palace and in the Football League for AFC Bournemouth, Gillingham, Swindon Town and Wolverhampton Wanderers. In 1999, he was called up to play international football by Nigeria, but injury prevented him from making his debut and he was never selected again.
Club career
Crystal Palace
Born in Camberwell, England, Ndah began his career as an apprentice at Crystal Palace, turning professional there in August 1992. Prior to that he had played youth-team football at Dulwich Hamlet. His older brother Jamie was also a footballer.
During his time at Selhurst Park he was loaned out twice. The first time was in 1995, when he played 15 games for AFC Bournemouth, then, two years later, he had a short spell at Gillingham, one that was curtailed by illness.
Swindon Town
Ndah moved to Swindon Town for £500,000, in November 1997, and in his two years with the Wiltshire side, he was a firm favourite of the crowd there. He scored 12 minutes into his debut against Middlesbrough on 22 November 1997.
Wolverhampton Wanderers
He departed for Wolverhampton Wanderers in October 1999, brought about by financial problems at the County Ground. He signed for Wolves at a cost of £1 million. Unfortunately his Wolves career suffered an early blow when his leg was broken by Matt Carbon during only his third

https://en.wikipedia.org/wiki/-ase
|
The suffix -ase is used in biochemistry to form names of enzymes. The most common way to name enzymes is to add this suffix onto the end of the substrate, e.g. an enzyme that breaks down peroxides may be called peroxidase; the enzyme that produces telomeres is called telomerase. Sometimes enzymes are named for the function they perform, rather than substrate, e.g. the enzyme that polymerizes (assembles) DNA into strands is called polymerase; see also reverse transcriptase.
Etymology
The -ase suffix is a libfix derived from "diastase", the first recognized enzyme. Its usage in subsequently discovered enzymes was proposed by Émile Duclaux, with the intention of honoring the first scientists to isolate diastase.

https://en.wikipedia.org/wiki/North%20Para%20River
|
The North Para River is a river located in the Barossa Valley of the Australian state of South Australia.
The river's name is based directly on the Kaurna word pari which means river. The "north" descriptor distinguishes it from the South Para River with which it merges.
Course and features
The North Para River rises in the Barossa Ranges near Eden Valley and follows a meandering path through the Barossa Valley, firstly north to the east of Angaston, then arcs around to the southwest to pass through the towns of Nuriootpa and Tanunda, before merging with the South Para River in Gawler forming the Gawler River. The river descends over its course.
The North Para River catchment is one of the key watersheds in the northern Mount Lofty Ranges. It plays a very important role in the economy of South Australia, providing much of the water used by viticulture in the Barossa Valley. Its waters are also used for livestock production, cereal cropping and recreation.

This is a list of Stonehenge replicas and derivatives that seeks to collect all the non-ephemeral examples together. The fame of the prehistoric monument of Stonehenge in England has led to many efforts to recreate it, using a variety of different materials, around the world. Some have been carefully built as astronomically aligned models whilst others have been examples of artistic expression or tourist attractions.
Astronomically aligned replicas
Australia and New Zealand
The only astronomically aligned, full-scale, "exact" replica of (a pristine) Stonehenge in natural stone (granite) is Esperance Stonehenge at Esperance, Western Australia. It cost over A$250,000 to build. Some of the blocks weigh more than 50 tonnes.
Stonehenge Aotearoa, in the Wairarapa region of New Zealand, is a modern adaptation aligned with the astronomy seen from the Antipodes. It was built by the Phoenix Astronomical Society from wood and sprayed concrete.
A full-scale replica in sandstone was started in the rural township of Buckland in Tasmania in the first years of the 21st century, but was demolished by order of the municipal authorities. It did not have the necessary planning approval from the local council.

https://en.wikipedia.org/wiki/Cell%20cycle%20checkpoint
|
Cell cycle checkpoints are control mechanisms in the eukaryotic cell cycle which ensure its proper progression. Each checkpoint serves as a potential termination point along the cell cycle, during which the conditions of the cell are assessed, with progression through the various phases of the cell cycle occurring only when favorable conditions are met. There are many checkpoints in the cell cycle, but the three major ones are: the G1 checkpoint, also known as the Start or restriction checkpoint or Major Checkpoint; the G2/M checkpoint; and the metaphase-to-anaphase transition, also known as the spindle checkpoint. Progression through these checkpoints is largely determined by the activation of cyclin-dependent kinases by regulatory protein subunits called cyclins, different forms of which are produced at each stage of the cell cycle to control the specific events that occur therein.
Background
All living organisms are the products of repeated rounds of cell growth and division. During this process, known as the cell cycle, a cell duplicates its contents and then divides in two. The purpose of the cell cycle is to accurately duplicate each organism's DNA and then divide the cell and its contents evenly between the two resulting cells. In eukaryotes, the cell cycle consists of four main stages: G1, during which a cell is metabolically active and continuously grows; S phase, during which DNA replication takes place; G2, during which cell growth continues and the cell synthesiz

https://en.wikipedia.org/wiki/Exonuclease%20III
|
Exonuclease III (ExoIII) is an enzyme that belongs to the exonuclease family. ExoIII catalyzes the stepwise removal of mononucleotides from 3´-hydroxyl termini of double-stranded DNA. A limited number of nucleotides are removed during each binding event, resulting in coordinated progressive deletions within the population of DNA molecules.
Function
The preferred substrates are blunt or recessed 3´-termini, although ExoIII also acts at nicks in duplex DNA to produce single-strand gaps. The enzyme is not active on single-stranded DNA, and thus 3´-protruding termini are resistant to cleavage. The degree of resistance depends on the length of the extension, with extensions 4 bases or longer being essentially resistant to cleavage. This property is used to produce unidirectional deletions from a linear molecule with one resistant (3´-overhang) and one susceptible (blunt or 5´-overhang) terminus.
ExoIII activity depends partially on the DNA helical structure and displays sequence dependence (C>A=T>G).
ExoIII has also been reported to have RNase H, 3´-phosphatase and AP-endonuclease activities.
Current Studies
There are many different exonucleases and many are still to be discovered in bacteria, current studies are being conducted in E. coli. Many exonucleases fall into superfamilies with different domains of life proving that exonuclease III has shown to be ancient. Exonucleases evolved early in the history of life and have vital biological roles.

It was during his reign that Mewar became one of the most powerful powers in the northern India. He was the most powerful sovereign of his time.
Early life
Rana Kumbha was born at Madariya, in a Hindu Rajput family of Sisodia clan. Kumbha was a son of Rana Mokal Singh of Mewar by his wife, Sobhagya Devi, a daughter of Jaitmal Sankhla, the Paramara fief-holder of Runkot in the state of Marwar. He was the 48th Rana of Mewar and succeeded Rana Mokal Singh in the year 1433 CE as the ruler of Mewar.
Early period
Kumbha's father was assassinated of his own kins named Chacha and Maira. However with the help of King of Marwar Rao Ranmal Rathore whom Mokal had helped to become the king. He was able to defeat the murderers of his father and secure the throne of Mewar for himself, but due to the growing powers of Rathores in Mewari court and Ranmal's influence among Rajputs. Kumbha had Ranmal assassinated and with the assassination of Ranmal, Kingdom of Marwar came into the hands of Kumbha. It took Jodha son of Ranmal seven years too re conqueror Marwar from Kumbha. When he was engaged with the sultan of Malwa but at the same time seeing the stable postion of Mewar and his depleted Kingdom, who could no afford a war. He made a truce.

https://en.wikipedia.org/wiki/Mdm2
|
Mouse double minute 2 homolog (MDM2) also known as E3 ubiquitin-protein ligase Mdm2 is a protein that in humans is encoded by the MDM2 gene. Mdm2 is an important negative regulator of the p53 tumor suppressor. Mdm2 protein functions both as an E3 ubiquitin ligase that recognizes the N-terminal trans-activation domain (TAD) of the p53 tumor suppressor and as an inhibitor of p53 transcriptional activation.
Discovery and expression in tumor cells
The murine double minute (mdm2) oncogene, which codes for the Mdm2 protein, was originally cloned, along with two other genes (mdm1 and mdm3) from the transformed mouse cell line 3T3-DM. Mdm2 overexpression, in cooperation with oncogenic Ras, promotes transformation of primary rodent fibroblasts, and mdm2 expression led to tumor formation in nude mice. The human homologue of this protein was later identified and is sometimes called Hdm2. Further supporting the role of mdm2 as an oncogene, several human tumor types have been shown to have increased levels of Mdm2, including soft tissue sarcomas and osteosarcomas as well as breast tumors. The MDM2 oncoprotein ubiquitinates and antagonizes p53 but may also carry out p53-independent functions. MDM2 supports the Polycomb-mediated repression of lineage-specific genes, independent of p53. MDM2 depletion in the absence of p53 promoted the differentiation of human mesenchymal stem cells and diminished clonogenic survival of cancer cells. Most of the MDM2-controlled genes also responded to th

|
In physics, a quantum mirage is a peculiar result in quantum chaos. Every system of quantum dynamical billiards will exhibit an effect called scarring, where the quantum probability density shows traces of the paths a classical billiard ball would take. For an elliptical arena, the scarring is particularly pronounced at the foci, as this is the region where many classical trajectories converge. The scars at the foci are colloquially referred to as the "quantum mirage".
The quantum mirage was first experimentally observed by Hari Manoharan, Christopher Lutz and Donald Eigler at the IBM Almaden Research Center in San Jose, California in 2000. The effect is quite remarkable but in general agreement with prior work on the quantum mechanics of dynamical billiards in elliptical arenas.
Quantum corral
The mirage occurs at the foci of a quantum corral, a ring of atoms arranged in an arbitrary shape on a substrate. The quantum corral was demonstrated in 1993 by Lutz, Eigler, and Crommie using an elliptical ring of iron atoms on a copper surface using the tip of a low-temperature scanning tunneling microscope to manipulate individual atoms. The ferromagnetic iron atoms reflected the surface electrons of the copper inside the ring into a wave pattern, as predicted by the theory of quantum mechanics.
Quantum corrals can be viewed as artificial atoms that even show similar chemical bonding properties as real atoms.
The size and shape of the corral determine its quantum states, inc

Strength in Numbers is an album by 24-7 Spyz. It is the only album to feature Jeff Brodnax, who replaced original vocalist P. Fluid in 1991. On their third effort, the Spyz concentrate on simpler and more direct songwriting. The album has been described as a hard rock album with elements of heavy metal, funk, New York hardcore, R&B, jazz and reggae.
The Seattle grunge movement overpowered the music industry in 1992, leaving the Spyz without a record contract or media attention in the midst of their creative peak.
After the release of the album, the Spyz would take a break before reforming their classic lineup in 1995.
Like many 24-7 Spyz albums, this recording is out of print but this album is available on streaming platforms.

https://en.wikipedia.org/wiki/Xenin
|
Xenin is a peptide hormone secreted from the chromogranin A-positive enteroendocrine cells called the K-cells in the mucous membrane of the duodenum and stomach of the upper gut. The peptide has been found in humans, dogs, pigs, rats, and rabbits.
In humans, xenin circulates in the blood plasma. There is a relationship between peaks of xenin concentration in the plasma and the third phase of the Migrating Motor Complex. For example, infusion of synthetic xenin in fasting volunteers will cause phase III activity. After a meal (the 'postprandial state'), infusion of xenin increases both frequency and the percentage of aborally propagated contractions. In higher concentrations xenin stimulates exocrine pancreatic secretion and inhibits the gastrin-stimulated secretion of acid in dogs. Xenin is also produced in neuroendocrine tumors of the duodenal mucosa.
In vitro, xenin interacts with the neurotensin receptor 1.
Structure and sequence
Xenin is a 25-amino acid polypeptide. The amino acid sequence of xenin is identical to the N-terminal end of cytoplasmic coatomer subunit alpha, from which xenin can be cleaved by aspartic proteases. Xenin is structurally related to the amphibian peptide xenopsin and to the neuropeptide neurotensin.
Surpassed by insulin, xenin reflects the second highest degree of homology traced along the evolutionary tree among the regulatory peptides, indicating its prominent structural conservatism.

Anerley () is an area of south east London, England, within the London Borough of Bromley. It is located south south-east of Charing Cross, to the south of Crystal Palace and Upper Norwood, west of Penge, north of Elmers End and South Norwood.
History
Origin and development
Anerley has never existed as an independent entity, but rather as a general area. Prior to the enclosure in 1827 and the relocation of the Crystal Palace to Penge Place at the top of Sydenham Hill, Anerley was an unoccupied part of Penge Common, and did not develop until the 19th century. The government Act of 1827 stipulated that a 50 feet (15 metres) wide, new road, was to be set out from Elmers End Road to what is now Church Road, Upper Norwood. In 1827, a Scottish silk manufacturer named William Sanderson bought land on the former Penge Common and built the first house in the area, which he named "Anerly Lodge", a Scottish and Northern English dialect word meaning "solitary" or "only", and the road subsequently became known as Anerley Road, also giving the name to the surrounding area. Sanderson's name is the first to appear in the first rate book, dated 18 June 1827, now held in the Anerley Town Hall.
Canal and railway
The Croydon Canal was opened on 22 October 1809, and passed through Anerley. The canal was a financial failure and lasted only 27 years, being sold to the London and Croydon Railway Company for £40,250. London and Croydon Railway would use much of the former canal for the new rail

NGC 3486 is an intermediate barred spiral galaxy located about 27.4 million light years away in the constellation of Leo Minor. It has a morphological classification of SAB(r)c, which indicates it is a weakly barred spiral with an inner ring and loosely wound arms. This is a borderline, low-luminosity Seyfert galaxy with an active nucleus. However, no radio or X-ray emission has been detected from the core, and it may only have a small supermassive black hole with less than a million times the mass of the Sun.

NGC 3521 is a flocculent intermediate spiral galaxy located around 26 million light-years away from Earth in the constellation Leo. It has a morphological classification of SAB(rs)bc, which indicates that it is a spiral galaxy with a trace of a bar structure (SAB), a weak inner ring (rs), and moderate to loosely wound arm structure (bc). The bar structure is difficult to discern, both because it has a low ellipticity and the galaxy is at a high inclination of 72.7° to the line of sight. The relatively bright bulge is nearly 3/4 the size of the bar, which may indicate the former is quite massive. The nucleus of this galaxy is classified as an HII LINER, as there is an H II region at the core and the nucleus forms a low-ionization nuclear emission-line region.

Jacques-Louis Lions (; 2 May 1928 – 17 May 2001) was a French mathematician who made contributions to the theory of partial differential equations and to stochastic control, among other areas. He received the SIAM's John von Neumann Lecture prize in 1986 and numerous other distinctions. Lions is listed as an ISI highly cited researcher.
Biography
After being part of the French Résistance in 1943 and 1944, Jacques-Louis Lions entered the École Normale Supérieure in 1947.
He was a professor of mathematics at the University of Nancy, the Faculty of Sciences of Paris, and the École Polytechnique.
In 1966 he sent an invitation to Gury Marchuk, the soviet mathematician to visit Paris. This was hand delivered by Général De Gaulle during his visit to Akademgorodok in June of that year.
He joined the prestigious Collège de France as well as the French Academy of Sciences in 1973.
In 1979, he was appointed director of the Institut National de la Recherche en Informatique et Automatique (INRIA), where he taught and promoted the use of numerical simulations using finite elements integration. Throughout his career, Lions insisted on the use of mathematics in industry, with a particular involvement in the French space program, as well as in domains such as energy and the environment.
This eventually led him to be appointed director of the Centre National d'Etudes Spatiales (CNES) from 1984 to 1992.

https://en.wikipedia.org/wiki/%CE%91-Galactosidase
|
α-Galactosidase ( EC 3.2.1.22, α-GAL, α-GAL A; systematic name α-D-galactoside galactohydrolase) is a glycoside hydrolase enzyme that catalyses the following reaction:
Hydrolysis of terminal, non-reducing α-D-galactose residues in α-D-galactosides, including galactose oligosaccharides, galactomannans and galactolipids
It catalyzes many catabolic processes, including cleavage of glycoproteins, glycolipids, and polysaccharides.
The enzyme is encoded by the GLA gene. Two recombinant forms of human α-galactosidase are called agalsidase α (INN) and agalsidase β (INN). A mold-derived form is the primary ingredient in gas relief supplements.
Function
This enzyme is a homodimeric glycoprotein that hydrolyses the terminal α-galactosyl moieties from glycolipids and glycoproteins. It predominantly hydrolyzes ceramide trihexoside, and it can catalyze the hydrolysis of melibiose into galactose and glucose.
Reaction mechanism
Disease relevance

Signs and Symptoms
Defects in human α-GAL result in Fabry disease, a rare lysosomal storage disorder and sphingolipidosis that results from a failure to catabolize α-D-galactosyl glycolipid moieties. Characteristic features include episodes of pain in hands and feet (acroparesthesia), dark red spots on skin (angiokeratoma), decreased sweating (hypohidrosis), decreased vision (corneal opacity), gastrointestinal problems, hearing loss, tinnitus, etc..

https://en.wikipedia.org/wiki/Homeostatic%20model%20assessment
|
The homeostatic model assessment (HOMA) is a method used to quantify insulin resistance and beta-cell function. It was first described under the name HOMA by Matthews et al. in 1985.
Derivation
The HOMA authors used data from physiological studies to develop mathematical equations describing glucose regulation as a feedback loop.
They published computer software that solves the equations, so that insulin resistance and β-cell function can be estimated from fasting glucose and insulin levels. They also published an equation (see below) that gave approximately the same answers as an early version of the computer software.
The computer model has since been improved to a HOMA2 model to better reflect human physiology and recalibrated to modern insulin assays. In this updated version it is possible to determine insulin sensitivity and β-cell function from paired fasting plasma glucose and radioimmunoassay insulin, specific insulin, or C-peptide concentrations. The authors recommend the computer software be used wherever possible.
Notes
The HOMA model was originally designed as a special case of a more general structural (HOMA-CIGMA) model that includes the continuous infusion of glucose with model assessment (CIGMA) approach; both techniques use mathematical equations to describe the functioning of the major effector organs influencing glucose/insulin interactions.
The approximating equation for insulin resistance, in the early model, used a fasting plasma sample, an

https://en.wikipedia.org/wiki/Pupillary%20distance
|
Pupillary distance (PD), more correctly known as interpupillary distance (IPD) is the distance in millimeters between the centers of each pupil.
Interpupillary Distance Classifications
Distance PD is the separation between the visual axes of the eyes in their primary position, as the subject fixates on an infinitely distant object.
Near PD is the separation between the visual axes of the eyes, at the plane of the spectacle lenses, as the subject fixates on a near object at the intended working distance.
Intermediate PD is at a specified plane in between distance and near.
Monocular PD refers to the distance between either the right or left visual axis to the bridge of the nose, which may be slightly different for each eye due to anatomical variations but always sums up to the binocular PD.
For people who need to wear prescription glasses, consideration of monocular PD measurement by an optician helps to ensure that the lenses will be located in the optimum position.
Whilst PD is an optometric term used to specify prescription eyewear, IPD is more critical for the design of binocular viewing systems, where both eye pupils need to be positioned within the exit pupils of the viewing system. These viewing systems include binocular microscopes, night vision devices or goggles (NVGs), and head-mounted displays (HMDs). IPD data are used in the design of such systems to specify the range of lateral adjustment of the exit optics or eyepieces. IPD is also used to describe the distan

https://en.wikipedia.org/wiki/Dilution%20%28equation%29
|
Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution. To dilute a solution means to add more solvent without the addition of more solute. The resulting solution is thoroughly mixed so as to ensure that all parts of the solution are identical.
The same direct relationship applies to gases and vapors diluted in air for example. Although, thorough mixing of gases and vapors may not be as easily accomplished.
For example, if there are 10 grams of salt (the solute) dissolved in 1 litre of water (the solvent), this solution has a certain salt concentration (molarity). If one adds 1 litre of water to this solution, the salt concentration is reduced. The diluted solution still contains 10 grams of salt (0.171 moles of NaCl).
Mathematically this relationship can be shown by equation:
where
c1 = initial concentration or molarity
V1 = initial volume
c2 = final concentration or molarity
V2 = final volume
....
Basic room purge equation
The basic room purge equation is used in industrial hygiene. It determines the time required to reduce a known vapor concentration existing in a closed space to a lower vapor concentration. The equation can only be applied when the purged volume of vapor or gas is replaced with "clean" air or gas. For example, the equation can be used to calculate the time required at a certain ventilation rate to reduce a high carbon monoxide concentr

https://en.wikipedia.org/wiki/Karmarkar%27s%20algorithm
|
Karmarkar's algorithm is an algorithm introduced by Narendra Karmarkar in 1984 for solving linear programming problems. It was the first reasonably efficient algorithm that solves these problems in polynomial time. The ellipsoid method is also polynomial time but proved to be inefficient in practice.
Denoting as the number of variables and as the number of bits of input to the algorithm, Karmarkar's algorithm requires operations on -digit numbers, as compared to such operations for the ellipsoid algorithm. The runtime of Karmarkar's algorithm is thus
using FFT-based multiplication (see Big O notation).
Karmarkar's algorithm falls within the class of interior-point methods: the current guess for the solution does not follow the boundary of the feasible set as in the simplex method, but moves through the interior of the feasible region, improving the approximation of the optimal solution by a definite fraction with every iteration and converging to an optimal solution with rational data.
The algorithm
Consider a linear programming problem in matrix form:
Karmarkar's algorithm determines the next feasible direction toward optimality and scales back by a factor . It is described in a number of sources. Karmarkar also has extended the method to solve problems with integer constraints and non-convex problems.
Since the actual algorithm is rather complicated, researchers looked for a more intuitive version of it, and in 1985 developed affine scaling, a version of Karmark

https://en.wikipedia.org/wiki/Apoptosome
|
The apoptosome is a large quaternary protein structure formed in the process of apoptosis. Its formation is triggered by the release of cytochrome c from the mitochondria in response to an internal (intrinsic) or external (extrinsic) cell death stimulus. Stimuli can vary from DNA damage and viral infection to developmental cues such as those leading to the degradation of a tadpole's tail.
In mammalian cells, once cytochrome c is released, it binds to the cytosolic protein Apaf-1 to facilitate the formation of an apoptosome. An early biochemical study suggests a two-to-one ratio of cytochrome c to apaf-1 for apoptosome formation. However, recent structural studies suggest the cytochrome c to apaf-1 ratio is one-to-one. It has also been shown that the nucleotide dATP as third component binds to apaf-1, however its exact role is still debated. The mammalian apoptosome had never been crystallized, but a human APAF-1/cytochrome-c apoptosome has been imaged at lower (2 nm) resolution by cryogenic transmission electron microscopy in 2002, revealing a heptameric wheel-like particle with 7-fold symmetry. Recently, a medium resolution (9.5 Ångström) structure of human apoptosome was also solved by cryo-electron microscopy, which allows unambiguous inference for positions of all the APAF-1 domains (CARD, NBARC and WD40) and cytochrome c. There is also now a crystal structure of the monomeric, inactive Apaf-1 subunit (PDB 3SFZ).
Once formed, the apoptosome can then recruit and activat

https://en.wikipedia.org/wiki/Agent%20%28economics%29
|
In economics, an agent is an actor (more specifically, a decision maker) in a model of some aspect of the economy. Typically, every agent makes decisions by solving a well- or ill-defined optimization or choice problem.
For example, buyers (consumers) and sellers (producers) are two common types of agents in partial equilibrium models of a single market. Macroeconomic models, especially dynamic stochastic general equilibrium models that are explicitly based on microfoundations, often distinguish households, firms, and governments or central banks as the main types of agents in the economy. Each of these agents may play multiple roles in the economy; households, for example, might act as consumers, as workers, and as voters in the model. Some macroeconomic models distinguish even more types of agents, such as workers and shoppers or commercial banks.
The term agent is also used in relation to principal–agent models; in this case, it refers specifically to someone delegated to act on behalf of a principal.
In agent-based computational economics, corresponding agents are "computational objects modeled as interacting according to rules" over space and time, not real people. The rules are formulated to model behavior and social interactions based on stipulated incentives and information. The concept of an agent may be broadly interpreted to be any persistent individual, social, biological, or physical entity interacting with other such entities in the context of a dynamic multi

|
Ethanol precipitation is a method used to purify and/or concentrate RNA, DNA, and polysaccharides such as pectin and xyloglucan from aqueous solutions by adding ethanol as an antisolvent.
DNA precipitation
Theory
DNA is polar due to its highly charged phosphate backbone. Its polarity makes it water-soluble (water is polar) according to the principle "like dissolves like".
Because of the high polarity of water, illustrated by its high dielectric constant of 80.1 (at 20 °C), electrostatic forces between charged particles are considerably lower in aqueous solution than they are in a vacuum or in air.
This relation is reflected in Coulomb's law, which can be used to calculate the force acting on two charges and separated by a distance by using the dielectric constant (also called relative static permittivity) of the medium in the denominator of the equation ( is an electric constant):
At an atomic level, the reduction in the force acting on a charge results from water molecules forming a hydration shell around it. This fact makes water a very good solvent for charged compounds like salts. Electric force which normally holds salt crystals together by way of ionic bonds is weakened in the presence of water allowing ions to separate from the crystal and spread through solution.
The same mechanism operates in the case of negatively charged phosphate groups on a DNA backbone: even though positive ions are present in solution, the relatively weak net electrostatic force pre

https://en.wikipedia.org/wiki/Differential%20extraction
|
Differential extraction (also known as differential lysis) refers to the process by which the DNA from two different types of cells can be extracted without mixing their contents. The most common application of this method is the extraction of DNA from vaginal epithelial cells and sperm cells from sexual assault cases in order to determine the DNA profiles of the victim and the perpetrator. Its success is based on the fact that sperm cells pack their DNA using protamines (rather than histones) which are held together by disulfide bonds. The protamines sequester DNA from spermatozoa, making it more resilient to DNA extraction than DNA from epithelial cells.
After determining that sperm cells are present (typically through staining and light microscopy) in a vaginal/rectal sample, the subject's epithelial cells are lysed by a standard DNA extraction method, like a phenol/chloroform extraction and their DNA extracted through normal means. The epithelial DNA in solution is removed and saved, while the sperm cell's DNA precipitates with the attached protamines. Differential extraction uses a chemical called dithiothreitol (DTT) to disrupt the sulfur bonds in the protamines in order to release its DNA. Once the DNA is detached from the protamines, it is prone to standard DNA extraction methods. This creates two different DNA fractions from one sample, that of the victim and that of the perpetrator.
However, the described method is difficult to carry out because it is both very l

The Stanton number, St, is a dimensionless number that measures the ratio of heat transferred into a fluid to the thermal capacity of fluid. The Stanton number is named after Thomas Stanton (engineer) (1865–1931). It is used to characterize heat transfer in forced convection flows.
Formula
where
h = convection heat transfer coefficient
ρ = density of the fluid
cp = specific heat of the fluid
u = velocity of the fluid
It can also be represented in terms of the fluid's Nusselt, Reynolds, and Prandtl numbers:
where
Nu is the Nusselt number;
Re is the Reynolds number;
Pr is the Prandtl number.
The Stanton number arises in the consideration of the geometric similarity of the momentum boundary layer and the thermal boundary layer, where it can be used to express a relationship between the shear force at the wall (due to viscous drag) and the total heat transfer at the wall (due to thermal diffusivity).
Mass transfer
Using the heat-mass transfer analogy, a mass transfer St equivalent can be found using the Sherwood number and Schmidt number in place of the Nusselt number and Prandtl number, respectively.

Turing's proof is a proof by Alan Turing, first published in January 1937 with the title "On Computable Numbers, with an Application to the ". It was the second proof (after Church's theorem) of the negation of Hilbert's ; that is, the conjecture that some purely mathematical yes–no questions can never be answered by computation; more technically, that some decision problems are "undecidable" in the sense that there is no single algorithm that infallibly gives a correct "yes" or "no" answer to each instance of the problem. In Turing's own words:
"what I shall prove is quite different from the well-known results of Gödel ... I shall now show that there is no general method which tells whether a given formula U is provable in K [Principia Mathematica]".
Turing followed this proof with two others. The second and third both rely on the first. All rely on his development of typewriter-like "computing machines" that obey a simple set of rules and his subsequent development of a "universal computing machine".
Summary of the proofs
In his proof that the Entscheidungsproblem can have no solution, Turing proceeded from two proofs that were to lead to his final proof. His first theorem is most relevant to the halting problem, the second is more relevant to Rice's theorem.
First proof: that no "computing machine" exists that can decide whether or not an arbitrary "computing machine" (as represented by an integer 1, 2, 3, . . .) is "circle-free" (i.e. goes on printing its number in bin

The Euler number (Eu) is a dimensionless number used in fluid flow calculations. It expresses the relationship between a local pressure drop caused by a restriction and the kinetic energy per volume of the flow, and is used to characterize energy losses in the flow, where a perfect frictionless flow corresponds to an Euler number of 0. The inverse of the Euler number is referred to as the Ruark Number with the symbol Ru.
The Euler number is defined as

In the book the authors analyze the world's economic and social structures by using the first and second laws of thermodynamics. The first and second law of thermodynamics — the second of which is known as the law of entropy — both deal with energy. The authors argue that technological nations are wasting resources such as fossil fuels and minerals at an increasing rate, which if unchecked will lead to the destruction of civilization, which has happened before on a smaller scale to past societies. The authors also argue that the societies wasting resources are exploiting the "Third World", now called "developing nations". The wasting of resources is a parallel to wasting energy in the laws of thermodynamics.
The Book promotes the use of sustainable energy sources and slow resource consumption as the solution to delay or forestall death by entropy including resource wars and the collapse of society.

A direct numerical simulation (DNS) is a simulation in computational fluid dynamics (CFD) in which the Navier–Stokes equations are numerically solved without any turbulence model. This means that the whole range of spatial and temporal scales of the turbulence must be resolved. All the spatial scales of the turbulence must be resolved in the computational mesh, from the smallest dissipative scales (Kolmogorov microscales), up to the integral scale , associated with the motions containing most of the kinetic energy. The Kolmogorov scale, , is given by

To satisfy these resolution requirements, the number of points along a given mesh direction with increments , must be

Hence, the memory storage requirement in a DNS grows very fast with the Reynolds number. In addition, given the very large memory necessary, the integration of the solution in time must be done by an explicit method. This means that in order to be accurate, the integration, for most discretization

|
Heinrich Wilhelm Gottfried von Waldeyer-Hartz (6 October 1836 – 23 January 1921) was a German anatomist, known for summarizing neuron theory and for naming the chromosome. He is also remembered by anatomical structures of the human body which were named after him: Waldeyer's tonsillar ring (the lymphoid tissue ring of the naso- and oropharynx) and Waldeyer's glands (of the eyelids).
Contribution to neuron theory
Waldeyer's name is associated in neuroscience with the "neuron theory", and for coining the term "neuron" to describe the basic structural unit of the nervous system. Waldeyer synthesized the discoveries by neuroanatomists (and later Nobel Prize winners) Camillo Golgi (1843–1926) and Santiago Ramón y Cajal (1852–1934), who had used the silver nitrate method of staining nerve tissue (Golgi's method), to formulate widely cited reviews of the theory. Waldeyer learned Spanish in order to absorb Cajal's detailed studies using Golgi's method and became his friend, mentor and promoter in the German-dominated field of microscopic anatomy. The theory was published in a series of papers in the main medical journal of Germany, Deutsche Medizinische Wochenschrift, which became extremely influential. However, as Cajal points out, though Waldeyer "supported the theory with the prestige of his authority, he did not contribute a single personal observation. He limited himself to a short brilliant exposition of the objective proofs, adduced by His, Kölliker, Retzius, van Gehuchten a

Synapse is a component-based development environment for neural networks and adaptive systems. Created by Peltarion, Synapse allows data mining, statistical analysis, visualization, preprocessing, design and training of neural networks and adaptive systems and the deployment of them. It utilizes a plug-in based architecture making it a general platform for signal processing. The first version of the product was released in May 2006.
Platform
Due to its plug in-based design, the usage of Synapse can be very general. Synapse is based on the Microsoft .NET framework and all Synapse components are also .NET components. Although Peltarion has yet to release an official API for the Synapse platform, user made components are emerging, some of them being original, demonstrating the openness of the platform.
Features
The development cycle in Synapse is based on the canonical data mining cycle. A notable difference however is that in Synapse that cycle is not linear, but supports an iterative approach where the user can freely move between the steps. Synapse features four different operating modes that make up the development cycle.
Preprocessing
The preprocessing mode is for data mining and data preparation. In this mode the user can import, visualize, explore and transform data in a variety of ways. Data is imported through the use of format components. The standard release includes format components for reading and writing data from CSV (text) files, SQL databases, images and XM

https://en.wikipedia.org/wiki/Yeast%20display
|
Yeast display (or yeast surface display) is a protein engineering technique that uses the expression of recombinant proteins incorporated into the cell wall of yeast for isolating and engineering antibodies.
Development
The yeast display technique was first published by the laboratory of Professor K. Dane Wittrup and Eric T. Boder. The technology was sold to Abbott Laboratories in 2001.
How it works
A protein of interest is displayed as a fusion to the Aga2p protein on the surface of yeast. The Aga2p protein is naturally used by yeast to mediate cell–cell contacts during yeast cell mating. As such, display of a protein via Aga2p projects the protein away from the cell surface, minimizing potential interactions with other molecules on the yeast cell wall. The use of magnetic separation and flow cytometry in conjunction with a yeast display library is a highly effective method to isolate high affinity protein ligands against nearly any receptor through directed evolution.
Advantages and disadvantages
Advantages of yeast display over other in vitro evolution methods include eukaryotic expression and processing, quality control mechanisms of the eukaryotic secretory pathway, minimal avidity effects, and quantitative library screening through fluorescent-activated cell sorting (FACS). Yeast are eukaryotic organisms that allow for complex post-translational modifications to proteins that no other display libraries are able to provide.
Disadvantages include smaller mutant libr

In the field of data management, data classification as a part of the Information Lifecycle Management (ILM) process can be defined as a tool for categorization of data to enable/help organizations to effectively answer the following questions:
What data types are available?
Where are certain data located?
What access levels are implemented?
What protection level is implemented and does it adhere to compliance regulations?
When implemented it provides a bridge between IT professionals and process or application owners. IT staff are informed about the data value and management (usually application owners) understands better which part of the data centre needs to be invested in to keep operations running effectively. This can be of particular importance in risk management, legal discovery, and compliance with government regulations. Data classification is typically a manual process; however, there are many tools from different vendors that can help gather information about the data.
Data classification needs to take into account the following:
Regulatory requirements
Strategic or proprietary worth
Organization specific policies
Ethical and privacy considerations
Contractual agreements
How to start process of data classification?
Note that this classification structure is written from a Data Management perspective and therefore has a focus for text and text convertible binary data sources. Images, videos, and audio files are highly structured formats built for industry

Maxwell's Equations, when converted to cylindrical coordinates, and with the boundary conditions for an optical fiber while including birefringence as an effect taken into account, will yield the coupled nonlinear Schrödinger equations. After employing the Inverse scattering transform (a procedure analogous to the Fourier Transform and Laplace Transform) on the resulting equations, the Manakov system is then obtained. The most general form of the Manakov system is as follows:
It is a coupled system of linear ordinary differential equations. The functions represent the envelope of the electromagnetic field as an initial condition.
For theoretical purposes, the integral equation version is often very useful. It is as follows:
One may make further substitutions and simplifications, depending on the limits used and the assumptions about boundary or initial conditions. One important concept is that is complex; assumptions must be made about this eigenvalue parameter. If a non-zero solution is desired, the imaginary part of the eigenvalue cannot change sign; accordingly, most researchers take the imaginary part to be positive.

https://en.wikipedia.org/wiki/Frequent%20urination
|
Frequent urination, or urinary frequency (sometimes called pollakiuria), is the need to urinate more often than usual. Diuretics are medications that increase urinary frequency. Nocturia is the need of frequent urination at night. The most common cause of this condition for women and children is a urinary tract infection. The most common cause of urinary frequency in older men is an enlarged prostate.
Frequent urination is strongly associated with frequent incidents of urinary urgency, which is the sudden need to urinate. It is often, though not necessarily, associated with urinary incontinence and polyuria (large total volume of urine). However, in other cases, urinary frequency involves only normal volumes of urine overall.
Definition
The normal number of times varies according to the age of the person. Among young children, urinating 8 to 14 times each day is typical. This decreases to 6–12 times per day for older children, and to 4–6 times per day among teenagers.
Causes
The most common causes of frequent urination are:
interstitial cystitis
urinary tract infection
enlarged prostate
urethral inflammation or infection
vaginal inflammation or infection.
Less common causes of frequent urination are:
alcoholism
anxiety
bladder cancer
caffeine
diabetes
pregnancy
psychiatric medications such as clozapine
radiation therapy to the pelvis
brain or nervous system diseases
stroke
tumor in the pelvis
kidney stones.

Triple Play was the name of the 2005 season FIRST Robotics Competition game.
Basic Description
Triple Play was the FIRST Robotics Competition game released on January 8, 2005. This is the first time the game rules PDF files were made available in late December to teams prior to the official release. The files with an alpha numeric password featuring the game's name. The password was 2005tr1pl3pl4y.
This game was the first to feature three robots per alliance. The primary game pieces were called "Tetras" which are tetrahedra made from PVC pipe long. The game was played on a field set up like a tic-tac-toe board, with nine larger goals, also shaped as tetras in three rows of three. The object of the game was to place the scoring tetras on the larger goals, creating rows of three by having a tetra of your alliance’s color at the highest point on the goal. Triple Play was a strategically intensive game, requiring quick thinking on the part of the drivers and operators to optimize the field for their alliance.
Game play
Tetras scored on the top of a goal were worth 3 points, while tetras contained inside the goals were worth 1 point. A goal was "owned" by the alliance whose color tetra highest on or inside the goal. Rows of three owned goals garnered the alliance an additional 10 points per at the end of regulation play. Ten points could also be scored if all three alliance robots were behind the alliance line at their end of the field at the end of the game.

Hydna of Scione (alternately called Hydne or Cyana) (fl. 480 BC) was an Ancient Greek swimmer and diver given credit for contributing to the destruction of the Persian navy in 480 BC.
Biography
According to Pausanias (Description of Greece, 10.19.1.), prior to a critical naval battle with the Persians, Hydna and her father, Scyllias, volunteered to assist Greek forces by vandalizing the nearby Persian naval fleet (likely a made-up propaganda story). After reaching Greece, Persian king Xerxes I had moored his ships off the coast of Mount Pelion to wait out a storm prior to the Battle of Artemisium. Hydna was well known in Greece as a skilled swimmer, having been trained by her father, a professional swim instructor named Scyllias, from a young age. She was known for her ability to swim long distances and dive deep into the ocean.
On the night of the attack, father and daughter swam roughly ten miles through rough, choppy waters to reach the ships. They silently swam among the boats, using knives to cut the moorings and dragging away the submerged anchors. Without anchors and moorings to secure the ships, they crashed together in the stormy water. Most of the ships sustained considerable damage and a few sank. The resulting delay allowed the Greek navy more time to prepare in Artemisium and ultimately led to a victory for Greek forces at Salamis.
In another chronicle by Herodotus, Scyllias was actually working for the Persians as a diver, recovering a great part of the treas

The Detroit Sleeper Cell is a group of men of Middle-Eastern descent who the United States Department of Justice believed were plotting an attack on Disneyland.
Trial
While on a trip to Disneyland, the four men recorded a home video. The Justice Department believed that this recording was reconnaissance for a future terror attack. This video, combined with the testimony of self-described con-artist Youssef Hmimssa, and what the defense called doodles in a day planner, but the prosecution called terror plans, led to the conviction of two men on June 3, 2003.
The prosecution claimed the five were "Takfiris" — followers of a radical Islamic sect that allowed mujahideen to drink alcohol, use narcotics, and refrain from praying, in order to blend into Western societies, so they could mount clandestine attacks on them.
Youssef Hmimssa, who pleaded guilty to multiple charges of credit card fraud and identity theft, agreed to testify against the four men, in a deal that would allow him to consolidate his other charges, and avoid further charges, reducing his sentence to between 37 and 46 months in prison. Defense attorneys Joseph A. Niskar, James C. Thomas, James Gerometta, Richard Helfrick, William Swor, Margaret Raben, and Robert Morgan were assigned to represent each individual member of the group. However, the attorneys argued the case together.
Post-trial
Later, the conviction of the two men was overturned by information indicating that the prosecution had withheld import

https://en.wikipedia.org/wiki/Paraphilic%20infantilism
|
Paraphilic infantilism, also known as autonepiophilia and adult baby, is a sexual fetish that involves role-playing a regression to an infant-like state. Paraphilic infantilism is a form of ageplay. People who practice paraphilic infantilism are often colloquially referred to (by themselves and others) as "adult babies", or "ABs".
Behaviors may include things such as wearing childish clothes, wearing or using diapers, cuddling with stuffed animals, drinking from a bottle or sucking on a pacifier, and (when done with others) engaging in gentle and nurturing experiences, baby talk, or BDSM power dynamics involving masochism, coercion, punishment or humiliation.
Paraphilic infantilism is often associated with diaper fetishism, a separate but related kink in which people derive sexual pleasure from themselves or others wearing or using diapers, without necessarily involving any form of ageplay. People with a diaper fetish are often informally called "diaper lovers", or "DLs". In practice, these strict labels do not always reflect the true diversity of sexual expression. As such, when considered together, paraphilic infantilism and diaper fetishism form a spectrum of behaviors that are often colloquially referred to under the umbrella term "adult baby/diaper lover", or "AB/DL" (also spelled "ABDL").
Like other sexual fetishes (paraphilias), there is no single recognized cause for paraphilic infantilism and little research has been done on the subject. A variety of theories hav

https://en.wikipedia.org/wiki/Atmospheric%20dispersion%20modeling
|
Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that include algorithms to solve the mathematical equations that govern the pollutant dispersion. The dispersion models are used to estimate the downwind ambient concentration of air pollutants or toxins emitted from sources such as industrial plants, vehicular traffic or accidental chemical releases. They can also be used to predict future concentrations under specific scenarios (i.e. changes in emission sources). Therefore, they are the dominant type of model used in air quality policy making. They are most useful for pollutants that are dispersed over large distances and that may react in the atmosphere. For pollutants that have a very high spatio-temporal variability (i.e. have very steep distance to source decay such as black carbon) and for epidemiological studies statistical land-use regression models are also used.
Dispersion models are important to governmental agencies tasked with protecting and managing the ambient air quality. The models are typically employed to determine whether existing or proposed new industrial facilities are or will be in compliance with the National Ambient Air Quality Standards (NAAQS) in the United States and other nations. The models also serve to assist in the design of effective control strategies to reduce emissions of harmful air pollutants. During the late 1960s, the Air Pol

Cylindrite is a sulfosalt mineral containing tin, lead, antimony and iron with formula: Pb3Sn4FeSb2S14. It forms triclinic pinacoidal crystals which often occur as tubes or cylinders which are in fact rolled sheets. It has a black to lead grey metallic colour with a Mohs hardness of 2 to 3 and a specific gravity of 5.4.
It was first discovered in the Santa Cruz mine, Oruro Department, Bolivia in 1893. The name arises from its curious cylindrical crystal which it forms almost uniquely among minerals.

Geigerite is a mineral, a complex hydrous manganese arsenate with formula: Mn5(AsO3OH)2(AsO4)2·10H2O. It forms triclinic pinacoidal, vitreous, colorless to red to brown crystals. It has a Mohs hardness of 3 and a specific gravity of 3.05.
It was discovered in Grischun, Switzerland in 1989. It was named
in honor of Thomas Geiger (1886–1976), Wiesendangen, Switzerland, who studied the Falotta manganese ores.
Composition
The chemical composition of geigerite is hydrous manganese arsenate (Mn5(AsO3OH)2(AsO4)2·10H2O). The chemical composition was found by using an electron microprobe in the Falotta mines in Switzerland.
Geologic occurrence
Geigerite can be found in the abandoned manganese mine in Oberhalbstein, Switzerland. It is mainly found in cavities in adiolarites, which are a form of igneous rock that have either a
radial or fanlike texture of crystals. Geigerite is then formed by metamorphism of manganese
oxide ores. Recently, geigerite has been found in Fukushima Prefecture, Japan. Geigerite has also been found in Mt. Nero Mine, Borghetto Di Vara, La Spieza, Italy.
Structure
Geigerite’s crystal system is triclinic with perfect cleavage on the {010}. The Herman Mauguin symbol for geigerite is and its space group is P. Geigerite contains two arsenate ions which are independent of one another. The first is the AsO3OH group, and the second is the AsO4. In the acidic AsO3OH group, the As-O bonds are much shorter than the As-OH bonds. Similarly, in the AsO4 group, As-O

https://en.wikipedia.org/wiki/GLI1
|
Zinc finger protein GLI1 also known as glioma-associated oncogene is a protein that in humans is encoded by the GLI1 gene. It was originally isolated from human glioblastoma cells.
Function
The Gli proteins are the effectors of Hedgehog (Hh) signaling and have been shown to be involved in cell fate determination, proliferation and patterning in many cell types and most organs during embryo development. In the developing spinal cord the target genes of Gli proteins, that are themselves transcription factors, are arranged into a complex gene regulatory network that translates the extracellular concentration gradient of Sonic hedgehog into different cell fates along the dorsoventral axis.
The Gli transcription factors activate/inhibit transcription by binding to Gli responsive genes and by interacting with the transcription complex. The Gli transcription factors have DNA binding zinc finger domains which bind to consensus sequences on their target genes to initiate or suppress transcription. Yoon showed that mutating the Gli zinc finger domain inhibited the proteins effect proving its role as a transcription factor. Gli proteins have an 18-amino acid region highly similar to the α-helical herpes simplex viral protein 16 activation domain. This domain contains a consensus recognition element for the human TFIID TATA box-binding protein associated factor TAFII31. Other proteins such as Missing in Metastasis (MIM/BEG4) have been shown to potentiate the effects of the Gli tr

https://en.wikipedia.org/wiki/GLI2
|
Zinc finger protein GLI2 also known as GLI family zinc finger 2 is a protein that in humans is encoded by the GLI2 gene. The protein encoded by this gene is a transcription factor.
GLI2 belongs to the C2H2-type zinc finger protein subclass of the Gli family. Members of this subclass are characterized as transcription factors which bind DNA through zinc finger motifs. These motifs contain conserved H-C links. Gli family zinc finger proteins are mediators of Sonic hedgehog (Shh) signaling and they are implicated as potent oncogenes in the embryonal carcinoma cell. The protein encoded by this gene localizes to the cytoplasm and activates patched Drosophila homolog (PTCH) gene expression. It is also thought to play a role during embryogenesis.
Isoforms
There are four isoforms: Gli2 alpha, beta, gamma and delta.
Structure
C-terminal activator and N-terminal repressor regions have been identified in both Gli2 and Gli3. However, the N-terminal part of human Gli2 is much smaller than its mouse or frog homologs, suggesting that it may lack repressor function.
Function
Gli2 affects ventroposterior mesodermal development by regulating at least three different genes; Wnt genes involved in morphogenesis, Brachyury genes involved in tissue specification and Xhox3 genes involved in positional information. The anti-apoptotic protein BCL-2 is up regulated by Gli2 and, to a lesser extent, Gli1 – but not Gli3, which may lead to carcinogenesis. Additionally, in the amphibian model organis

|
Zinc finger protein GLI3 is a protein that in humans is encoded by the GLI3 gene.
This gene encodes a protein that belongs to the C2H2-type zinc finger proteins subclass of the Gli family. They are characterized as DNA-binding transcription factors and are mediators of Sonic hedgehog (Shh) signaling. The protein encoded by this gene localizes in the cytoplasm and activates patched Drosophila homolog (PTCH1) gene expression. It is also thought to play a role during embryogenesis.
Role in development
Gli3 is a known transcriptional repressor but may also have a positive transcriptional function. Gli3 represses dHand and Gremlin, which are involved in developing digits. There is evidence that Shh-controlled processing (e.g., cleavage) regulates transcriptional activity of Gli3 similarly to that of Ci. Gli3 mutant mice have many abnormalities including CNS and lung defects and limb polydactyly. In the developing mouse limb bud, Gli3 derepression predominantly regulates Shh target genes.
Disease association
Mutations in this gene have been associated with several diseases, including Greig cephalopolysyndactyly syndrome, Pallister–Hall syndrome, preaxial polydactyly type IV, and postaxial polydactyly types A1 and B. DNA copy-number alterations that contribute to increased conversion of the oncogenes Gli1–3 into transcriptional activators by the Hedgehog signaling pathway are included in a genome-wide pattern, which was found to be correlated with an astrocytoma patient's ou

https://en.wikipedia.org/wiki/Ocular%20dominance%20column
|
Ocular dominance columns are stripes of neurons in the visual cortex of certain mammals (including humans) that respond preferentially to input from one eye or the other. The columns span multiple cortical layers, and are laid out in a striped pattern across the surface of the striate cortex (V1). The stripes lie perpendicular to the orientation columns.
Ocular dominance columns were important in early studies of cortical plasticity, as it was found that monocular deprivation causes the columns to degrade, with the non-deprived eye assuming control of more of the cortical cells.
It is believed that ocular dominance columns must be important in binocular vision. Surprisingly, however, many squirrel monkeys either lack or partially lack ocular dominance columns, which would not be expected if they are useful. This has led some to question whether they serve a purpose, or are just a byproduct of development.
History
Discovery
Ocular dominance columns were discovered in the 1960s by Hubel and Wiesel as part of their Nobel prize winning work on the structure of the visual cortex in cats. Ocular dominance columns have since been found in many animals, such as ferrets, macaques, and humans. Notably, they are also absent in many animals with binocular vision, such as rats.

Ocular dominance columns are stripe shaped regions of the primary visual cortex that lie perpendicular to the orientation columns, as can be seen in the accompanying figure. Different species have

https://en.wikipedia.org/wiki/Additive%20increase/multiplicative%20decrease
|
The additive-increase/multiplicative-decrease (AIMD) algorithm is a feedback control algorithm best known for its use in TCP congestion control. AIMD combines linear growth of the congestion window when there is no congestion with an exponential reduction when congestion is detected. Multiple flows using AIMD congestion control will eventually converge to an equal usage of a shared link. The related schemes of multiplicative-increase/multiplicative-decrease (MIMD) and additive-increase/additive-decrease (AIAD) do not reach stability.
Algorithm
The approach taken is to increase the transmission rate (window size), probing for usable bandwidth, until loss occurs. The policy of additive increase may, for instance, increase the congestion window by a fixed amount every round-trip time. When congestion is detected, the transmitter decreases the transmission rate by a multiplicative factor; for example, cut the congestion window in half after loss. The result is a saw-tooth behavior that represents the process of bandwidth probing.
AIMD requires a binary congestion signal. Most frequently, packet loss serves as the signal; the multiplicative decrease is triggered when a timeout or an acknowledgement message indicates a packet lost. It is also possible for in-network switches/routers to mark congestion (without discarding packets) as in Explicit Congestion Notification (ECN).

|
The chief electrical characteristic of a dynamic loudspeaker's driver is its electrical impedance as a function of frequency. It can be visualized by plotting it as a graph, called the impedance curve.
Explanation
The most common driver type is an electro-mechanical transducer using a voice coil rigidly connected to a diaphragm (generally a cone). Other types have similar connections, though differing in detail, between their acoustical environment and their electrical properties.
The voice coil in moving coil drivers is suspended in a magnetic field provided by the loudspeaker magnet structure. As electric current flows through the voice coil (from an electronic amplifier), the magnetic field created by the coil reacts against the magnet's fixed field and moves the voice coil (and so the cone). Alternating current will move the cone back and forth.
Resonance
The moving system of the loudspeaker—consisting of the cone, cone suspension, spider, and voice coil—can be modeled as an effective mass (spring–mass system), a mass suspended by a spring. This system has a characteristic mass and stiffness, and a resonant frequency at which the system will vibrate freely.
This frequency is known as the "free-space resonance" of the loudspeaker and is designated by Fs. At this frequency, the voice coil is vibrating in the speaker's magnetic field with maximum peak-to-peak amplitude and velocity. The back EMF generated by this movement is also at its maximum.

Torricelli's law, also known as Torricelli's theorem, is a theorem in fluid dynamics relating the speed of fluid flowing from an orifice to the height of fluid above the opening. The law states that the speed of efflux of a fluid through a sharp-edged hole at the bottom of the tank filled to a depth is the same as the speed that a body (in this case a drop of water) would acquire in falling freely from a height , i.e. , where is the acceleration due to gravity. This expression comes from equating the kinetic energy gained, , with the potential energy lost, , and solving for . The law was discovered (though not in this form) by the Italian scientist Evangelista Torricelli, in 1643. It was later shown to be a particular case of Bernoulli's principle.
Derivation
Under the assumptions of an incompressible fluid with negligible viscosity, Bernoulli's principle states that the hydraulic energy is constant
at any two points in the flowing liquid. Here is fluid speed, is the acceleration due to gravity, is the height above some reference point, is the pressure, and is the density.
In order to derive Torricelli's formula the first point with no index is taken at the liquid's surface, and the second just outside the opening. Since the liquid is assumed to be incompressible, is equal to and ; both can be represented by one symbol . The pressure and are typically both atmospheric pressure, so . Furthermore
is equal to the height of the liquid's surface over the openin

Linear Technology Corporation was an American semiconductor company that designed, manufactured and marketed high performance analog integrated circuits. Applications for the company's products included telecommunications, cellular telephones, networking products, notebook and desktop computers, video/multimedia, industrial instrumentation, automotive electronics, factory automation, process control, military and space systems. The company was founded in 1981 by Robert H. Swanson, Jr. and Robert C. Dobkin.
In July 2016, Analog Devices agreed to buy Linear Technology for 14.8 billion dollars. This acquisition was finalized on March 10, 2017. The Linear name survives as the "Power by Linear" brand that is used to market the combined power management portfolios of Linear Technology and Analog Devices.
Products
As of August 2010, the company made over 7500 products, which they organized into seven product categories: data conversion (analog to digital converters, digital to analog converters), signal conditioning (operational amplifiers, comparators, voltage references), power management (switching regulators, linear regulators, battery management, LED drivers), interface (RS232, RS485), radio frequency (mixers, quadrature modulators), oscillators, and space and military ICs.
The company maintained LTspice, a freely downloadable version of SPICE that includes schematic capture.
Locations
Corporate headquarters were in Milpitas, California. In the United States, the company
