https://en.wikipedia.org/wiki/Kendall%27s%20notation
|
In queueing theory, a discipline within the mathematical theory of probability, Kendall's notation (or sometimes Kendall notation) is the standard system used to describe and classify a queueing node. D. G. Kendall proposed describing queueing models using three factors written A/S/c in 1953 where A denotes the time between arrivals to the queue, S the service time distribution and c the number of service channels open at the node. It has since been extended to A/S/c/K/N/D where K is the capacity of the queue, N is the size of the population of jobs to be served, and D is the queueing discipline.
When the final three parameters are not specified (e.g. M/M/1 queue), it is assumed K = ∞, N = ∞ and D = FIFO.
First example: M/M/1 queue
A M/M/1 queue means that the time between arrivals is Markovian (M), i.e. the inter-arrival time follows an exponential distribution of parameter λ. The second M means that the service time is Markovian: it follows an exponential distribution of parameter μ. The last parameter is the number of service channel which one (1).
Description of the parameters
In this section, we describe the parameters A/S/c/K/N/D from left to right.
A: The arrival process
A code describing the arrival process. The codes used are:
S: The service time distribution
This gives the distribution of time of the service of a customer. Some common notations are:
c: The number of servers
The number of service channels (or servers). The M/M/1 queue has a single server a

https://en.wikipedia.org/wiki/Paul%20Hinshelwood
|
Paul Alexander Hinshelwood (14 August 1956 – 15 January 2022) was an English footballer who played as a right-back in the Football League for Crystal Palace, Oxford United, Millwall and Colchester United. He gained representative honours with the England under-21 team and also played and managed in non-league football. His sons Adam and Paul jr. were also professional footballers.
Early life
Hinshelwood was born in Bristol on 14 August 1956, and grew up in Croydon. In 1969, along with his brother Martin, he played in the final of the London FA Schools Cup, watched by former Crystal Palace manager Arthur Rowe. Rowe was impressed, and the brothers were invited for trials with the club. Both performed well, and were taken on as apprentices.
Career
"Doris", as he was known by the fans, although his dressing room nickname was "Fish", originally began as a striker, but did not play that well in the role. In November 1976, Hinshelwood switched to playing at right-back. Along with future England left-back Kenny Sansom, he shored up the Palace defence, and the club were promoted twice in three seasons, to reach the First Division in 1979. In that season, Hinshelwood only missed one game, as Palace went up as champions.
Palace spent two years in the top flight, and Hinshelwood was voted as the fans' "Player of the Year" for both. As well as this, he gained two caps for the England under-21 side.
Hinshelwood left Palace in 1983, transferring to Oxford United. There, he won the Thir

https://en.wikipedia.org/wiki/Electroneutral%20cation-Cl
|
In molecular biology, the electroneutral cation-Cl (electroneutral potassium chloride cotransporter) family of proteins are a family of solute carrier proteins. This family includes the products of the Human genes: SLC12A1, SLC12A1, SLC12A2, SLC12A3, SLC12A4, SLC12A5, SLC12A6, SLC12A7, SLC12A8 and SLC12A9.
The K-Cl co-transporter (KCC) mediates the coupled movement of K+ and Cl− ions across the plasma membrane of many animal cells. This transport is involved in the regulatory volume decrease in response to cell swelling in red blood cells, and has been proposed to play a role in the vectorial movement of Cl− across kidney epithelia. The transport process involves one for one electroneutral movement of K+ together with Cl−, and, in all known mammalian cells, the net movement is outward.
The neuronal KCC subtype KCC2 is cell-volume insensitive and plays a unique role in maintaining low intracellular Cl−concentration, which is required in neurones for the functioning of Cl− dependent fast synaptic inhibition, mediated by certain neurotransmitters, such as gamma-aminobutyric acid (GABA) and glycine.
Three isoforms of the K-Cl co-transporter have been described, termed KCC1 (SLC12A4), KCC2 (SLC12A5), and KCC3 (SLC12A6), containing 1085, 1116 and 1150 amino acids, respectively. They are predicted to have 12 transmembrane (TM) regions in a central hydrophobic domain, together with hydrophilic N- and C-termini that are likely cytoplasmic.

https://en.wikipedia.org/wiki/Diphenyl%20disulfide
|
Diphenyl disulfide is the chemical compound with the formula (C6H5S)2. This colorless crystalline material is often abbreviated Ph2S2. It is one of the more commonly encountered organic disulfides in organic synthesis. Minor contamination by thiophenol is responsible for the disagreeable odour associated with this compound.
Preparation and structure
Diphenyl disulfide is usually prepared by the oxidation of thiophenol:
2 PhSH + I2 → Ph2S2 + 2 HI
Hydrogen peroxide can also be used as the oxidant. Ph2S2 is rarely prepared in the laboratory because it is inexpensive, and the precursor has a disagreeable odour.
Like most organic disulfides, the C–S–S–C core of Ph2S2 is non-planar with a dihedral angle approaching 85°.
Reactions
Ph2S2 is mainly used in organic synthesis as a source of the PhS substituent.<ref>{{cite book|author=Byers, J. H.|chapter=Diphenyl Disulfide|title=Encyclopedia of Reagents for Organic Synthesis (Ed: L. Paquette)|year=2004|editor=J.

A family of musical instruments is a grouping of several different but related sizes or types of instruments. Some schemes of musical instrument classification, such as the Hornbostel-Sachs system, are based on a hierarchy of instrument families and families of families.
Some commonly recognized families are:
Strings family
Woodwind family
Brass family
Percussion family
Electronic family
Some less common families are:
Idiophone family
Plasmaphone family
Hydraulophone family
Free Reed subfamily (woodwind)
Aeolian Instrument family
The keyboard family can also be referenced, though it is not an authentic instrument family. Rather, it is a common design format for instrument interfaces. There are many types of instruments in the keyboard family, such as string, brass (and other metals), woodwind, percussion, electronic, digital, idiophone, and more.
Instruments can also be classified by audio generation method. There are chordophones (generate sound with vibrating strings), membranophones (generate sound with vibrating membranes), idiophones (generate sound by vibrating the instrument body), aerophones (generate sound by vibrating air directly), electrophones (generate sound by modifying circuits or calculating sounds and outputting to a speaker, or potentially arcing electricity or vibrating metal with an electromagnet), plasmaphones (generate sound by exciting air with plasma), and hydraulophones (generate sound by vibrating air with hydraulics).

https://en.wikipedia.org/wiki/Naringinase
|
Naringinase is a debittering enzyme that is used in the commercial production of citrus juices. It breaks down the compound naringin that gives citrus juices its bitter taste. It is a multienzyme complex which possesses alpha-L-rhamnosidase and beta glucosidase active centers. The E.C. No.() of the naringinase and rhamnosidase are the same. First rhamnosidase breaks naringin into prunin and rhamnose. Lastly glucosidase breaks prunin into glucose and naringenin, a flavorless flavanone also found in various citrus.
Ram gene is a rare gene; it is found in very few microorganisms, like some Bacillus species. It is mainly present in the genus Aspergillus, but production of naringinase from fungus is a difficult task as the growth rate of fungi is much slower than that of bacteria.

https://en.wikipedia.org/wiki/Calponin
|
Calponin is a calcium binding protein. Calponin tonically inhibits the ATPase activity of myosin in smooth muscle. Phosphorylation of calponin by a protein kinase, which is dependent upon calcium binding to calmodulin, releases the calponin's inhibition of the smooth muscle ATPase.
Structure and function
Calponin is mainly made up of α-helices with hydrogen bond turns. It is a binding protein and is made up of three domains. These domains in order of appearance are Calponin Homology (CH), regulatory domain (RD), and Click-23, domain that contains the calponin repeats. At the CH domain calponin binds to α-actin and filamin and binds to actin within the RD domain. Calmodulin, when activated by calcium may bind weakly to the CH domain and inhibit calponin binding with α-actin. Calponin is responsible for binding many actin binding proteins, phospholipids, and regulates the actin/myosin interaction. Calponin is also thought to negatively affect the bone making process due to being expressed in high amounts in osteoblasts.

https://en.wikipedia.org/wiki/Caldesmon
|
Caldesmon is a protein that in humans is encoded by the CALD1 gene.
Caldesmon is a calmodulin binding protein. Like calponin, caldesmon tonically inhibits the ATPase activity of myosin in smooth muscle.
This gene encodes a calmodulin- and actin-binding protein that plays an essential role in the regulation of smooth muscle and nonmuscle contraction. The conserved domain of this protein possesses the binding activities to -calmodulin, actin, tropomyosin, myosin, and phospholipids. This protein is a potent inhibitor of the actin-tropomyosin activated myosin MgATPase, and serves as a mediating factor for -dependent inhibition of smooth muscle contraction. Alternative splicing of this gene results in multiple transcript variants encoding distinct isoforms.
Immunochemistry
In diagnostic immunochemistry, caldesmon is a marker for smooth muscle differentiation.

https://en.wikipedia.org/wiki/Plateau%E2%80%93Rayleigh%20instability
|
In fluid dynamics, the Plateau–Rayleigh instability, often just called the Rayleigh instability, explains why and how a falling stream of fluid breaks up into smaller packets with the same volume but less surface area. It is related to the Rayleigh–Taylor instability and is part of a greater branch of fluid dynamics concerned with fluid thread breakup. This fluid instability is exploited in the design of a particular type of ink jet technology whereby a jet of liquid is perturbed into a steady stream of droplets.
The driving force of the Plateau–Rayleigh instability is that liquids, by virtue of their surface tensions, tend to minimize their surface area. A considerable amount of work has been done recently on the final pinching profile by attacking it with self-similar solutions.
History
The Plateau–Rayleigh instability is named for Joseph Plateau and Lord Rayleigh. In 1873, Plateau found experimentally that a vertically falling stream of water will break up into drops if its length is greater than about 3.13 to 3.18 times its diameter, which he noted is close to . Later, Rayleigh showed theoretically that a vertically falling column of non-viscous liquid with a circular cross-section should break up into drops if its length exceeded its circumference, which is indeed times its diameter.
Theory
The explanation of this instability begins with the existence of tiny perturbations in the stream. These are always present, no matter how smooth the stream is (for example,

https://en.wikipedia.org/wiki/Adaptive%20response
|
The adaptive response is a form of direct DNA repair in E. coli that protects DNA from damage by external agents or by errors during replication. It is initiated against alkylation, particularly methylation, of guanine or thymine nucleotides or phosphate groups on the sugar-phosphate backbone of DNA. Under sustained exposure to low-level treatment with alkylating mutagens, E. coli can adapt to the presence of the mutagen, rendering subsequent treatment with high doses of the same agent less effective.
This mechanism has four related genes, also known as “SOS genes”: ada, alkA, alkB, and aidB, each one working in specific residues, all regulated by ada protein.
The adaptive response is mediated by the ada protein (a part of the ada regulon), which covalently transfers alkyl groups from the damaged DNA to one of its two active methyl acceptor cysteine residues: Cys69 and Cys321. Ada protein can repair the damage by transferring methyl groups from O6-methylguanine or O4-methylthymine to Cys321 and also from methylphosphotriesters to Cys69 residue through an irreversible process. It can also convert the protein from a weak to a strong activator of transcription, increasing alkylation repair activity.

https://en.wikipedia.org/wiki/N-Myc
|
N-myc proto-oncogene protein also known as N-Myc or basic helix-loop-helix protein 37 (bHLHe37), is a protein that in humans is encoded by the MYCN gene.
Function
The MYCN gene is a member of the MYC family of transcription factors and encodes a protein with a basic helix-loop-helix (bHLH) domain. This protein is located in the cell nucleus and must dimerize with another bHLH protein in order to bind DNA. N-Myc is highly expressed in the fetal brain and is critical for normal brain development.
The MYCN gene has an antisense RNA, N-cym or MYCNOS, transcribed from the opposite strand which can be translated to form a protein product. N-Myc and MYCNOS are co-regulated both in normal development and in tumor cells, so it is possible that the two transcripts are functionally related. It has been shown that the antisense RNA encodes for a protein, named NCYM, that has originated de novo and is specific to human and chimpanzee. This NCYM protein inhibits GSK3b and thus prevents MYCN degradation. Transgenic mice that harbor human MYCN/NCYM pair often show neuroblastomas with distant metastasis, which are atypical for normal mice. Thus NCYM represents a rare example of a de novo gene that has acquired molecular function and plays a major role in oncogenesis.
Clinical significance
Amplification and overexpression of N-Myc can lead to tumorigenesis. Excess N-Myc is associated with a variety of tumors, most notably neuroblastomas where patients with amplification of the N-Myc gene

https://en.wikipedia.org/wiki/Orosomucoid
|
Orosomucoid (ORM) or alpha-1-acid glycoprotein (α1AGp, AGP or AAG) is an acute phase protein found in plasma. It is an alpha-globulin glycoprotein and is modulated by two polymorphic genes. It is synthesized primarily in hepatocytes and has a normal plasma concentration between 0.6–1.2 mg/mL (1–3% plasma protein). Plasma levels are affected by pregnancy, burns, certain drugs, and certain diseases, particularly HIV.
The only established function of ORM is to act as a carrier of basic and neutrally charged lipophilic compounds. In medicine, it is known as the primary carrier of basic (negatively charged) drugs (whereas albumin carries acidic (positively charged) and neutral drugs), steroids, and protease inhibitors. Aging causes a small decrease in plasma albumin levels; if anything, there is a small increase in alpha-1-acid glycoprotein. The effect of these changes on drug protein binding and drug delivery, however, appear to be minimal. AGP shows a complex interaction with thyroid homeostasis: AGP in low concentrations was observed to stimulate the thyrotropin (TSH) receptor and intracellular accumulation of cyclic AMP. High AGP concentrations, however, inhibited TSH signalling.
Alpha-1-acid glycoprotein has been identified as one of four potentially useful circulating biomarkers for estimating the five-year risk of all-cause mortality (the other three are albumin, very low-density lipoprotein particle size, and citrate).

https://en.wikipedia.org/wiki/Pannexin
|
Pannexins (from Greek 'παν' — all, and from Latin 'nexus' — connection) are a family of vertebrate proteins identified by their homology to the invertebrate innexins. While innexins are responsible for forming gap junctions in invertebrates, the pannexins have been shown to predominantly exist as large transmembrane channels connecting the intracellular and extracellular space, allowing the passage of ions and small molecules between these compartments (such as ATP and sulforhodamine B).
Three pannexins have been described in Chordates: Panx1, Panx2 and Panx3.
Function
Pannexins can form nonjunctional transmembrane channels for transport of molecules of less than 1000 Da. These hemichannels can be present in plasma, ER and Golgi membranes. They transport Ca2+, ATP, inositol triphosphate and other small molecules and can form hemichannels with greater ease than connexin subunits. Pannexin 1 and pannexin 2 underlie channel function in neurons and contribute to ischemic brain damage.
Pannexin 1 has been shown to be involved in early stages of innate immunity through an interaction with the P2X7 purinergic receptor. Activation of the pannexin channel through binding of ATP to P2X7 receptor leads to the release of interleukin-1β.
Hypothetical roles of pannexins in the nervous system include participating in sensory processing, synchronization between hippocampus and cortex, hippocampal plasticity, and propagation of calcium waves. Calcium waves are supported by glial cells,

https://en.wikipedia.org/wiki/Innexin
|
Innexins are transmembrane proteins that form gap junctions in invertebrates. Gap junctions are composed of membrane proteins that form a channel permeable to ions and small molecules connecting the cytoplasm of adjacent cells. Although gap junctions provide similar functions in all multicellular organisms, it was not known what proteins invertebrates used for this purpose until the late 1990s. While the connexin family of gap junction proteins was well-characterized in vertebrates, no homologues were found in non-chordates.
Innexins or related proteins are widespread among Eumetazoa, with the exception of echinoderms.
Discovery
Gap junction proteins with no sequence homology to connexins were initially identified in fruit flies. It was suggested that these proteins are specific invertebrate gap junctions, and they were thus named "innexins" (invertebrate analog of connexins). They were later identified in diverse invertebrates. Invertebrate genomes may contain more than a dozen innexin genes. Once the human genome was sequenced, innexin homologues were identified in humans and then in other vertebrates, indicating their ubiquitous distribution in the animal kingdom. These homologues were called "pannexins" (from the Greek pan - all, throughout, and Latin nexus - connection, bond). However, increasing evidence suggests that pannexins do not form gap junctions unless overexpressed in tissue and thus, differ functionally from innexins.
Structure
Innexins have four transmem

The Ukrainian T-shaped Radio telescope, second modification (official abbreviation UTR-2) is the world's largest low-frequency radio telescope at decametre wavelengths. It was completed in 1972 near the village of Hrakovo (), 15 km west-south-west from Shevchenkove, Ukraine. The telescope is operated by the Institute of Radio Astronomy of the Ukrainian Academy of Sciences.
The UTR-2 consists of an array of 2040 dipole elements in two arms each containing 6 rows of elements, oriented in a T shape: a north–south arm consisting of 1440 elements covering an area of 1800×60 meters, and an east–west arm consisting of 600 elements covering an area of 900×60 meters. The basic element is a broadband cage dipole 1.8 m in diameter and 8 m long made of galvanized steel wire, mounted 3.5 m above the ground, with a balun to connect it to the transmission line. The dipoles are all oriented along the east–west axis, with the spacing between rows of 7.5 m in east–west direction and 9 m in north–south. It has a total area of , and a resolution of about 40 arcminutes at the middle frequency 16.7 MHz. The operating frequency range is 8–33 MHz. The sensitivity is about 10 mJy.
Steering of the antenna main lobe is accomplished with phase shifters consisting of switchable delay lines.

https://en.wikipedia.org/wiki/Craniofrontonasal%20dysplasia
|
Craniofrontonasal dysplasia (craniofrontonasal syndrome, craniofrontonasal dysostosis, CFND) is a very rare X-linked malformation syndrome caused by mutations in the ephrin-B1 gene (EFNB1). Phenotypic expression varies greatly amongst affected individuals, where females are more commonly and generally more severely affected than males. Common physical malformations are: craniosynostosis of the coronal suture(s), orbital hypertelorism, bifid nasal tip, dry frizzy curled hair, longitudinal ridging and/or splitting of the nails, and facial asymmetry.
The diagnosis CFND is determined by the presence of a mutation in the EFNB1 gene. Physical characteristics may play a supportive role in establishing the diagnosis.
The treatment is always surgical and is based on each patients specific phenotypic presentation.
Presentation
Phenotypic expression varies greatly between individuals with CFND. Some of the more prominent characteristics are:
Craniosynostosis of the coronal suture(s) (fusion of the coronal sutures),
Orbital hypertelorism (increased interocular distance),
Bifid nasal tip,
Dry frizzy curled hair,
Longitudinal ridging and / or splitting of the nails,
Facial Asymmetry.
Other characteristics that are less frequently seen are: broad nasal base, low anterior hair line, low set ears, crowding of the teeth, maxillary hypoplasia, rounded and sloping shoulders, pectus excavatum, scoliosis, high arched palate, orbital dystopia, low implant of the breasts with asy

was a Japanese mathematician specializing in algebra who attended University of Tokyo in Japan. Morishima published at least thirteen papers, including his work on Fermat's Last Theorem. and a collected works volume published in 1990 after his death. He also corresponded several times with American mathematician H. S. Vandiver.
Morishima's Theorem on FLT
Let m be a prime number not exceeding 31. Let p be prime, and let x, y, z be integers such that xp + yp + zp = 0. Assume that p does not divide the product xyz. Then, p² must divide mp − 1-1.
Review
Granville wrote that Morishima's proof could not be accepted.

|
Robotman (Clifford "Cliff" Steele, called Automaton in first two appearances) is a superhero appearing in American comic books published by DC Comics. He is best known as a member of the Doom Patrol, being the only character to appear in every version of the team since its introduction in June 1963.
Robotman has appeared in numerous cartoon television shows and films. Robotman made his first live adaptation as a guest star on the Titans television series for DC Universe played by Jake Michaels. Riley Shanahan took over from Michaels in the role. He is part of the main cast of its spin-off Doom Patrol which is also on Max. Brendan Fraser provides the voice of Robotman and portrays Cliff Steele in flashbacks in the series.
Publication history
Robotman first appeared in My Greatest Adventure #80 (June 1963) and was created by Arnold Drake and Bruno Premiani. According to Drake, the issue's co-writer Bob Haney was not brought on to the project until after Robotman was created. He commented on the character's original name, Automaton:
That name was pretty stupid. I've been responsible for a lot of stupid things, but that was one of the stupidest, so, within two issues, I figured that out and changed his name to Robotman.
At the time, Drake didn't realize that there had been a previous character named Robotman, published in 1942-1953 during the Golden Age of Comic Books. DC's previous Robotman also had a human brain.
Robotman was the only original member of the Doom Patrol to a

|
In bioinformatics, the general feature format (gene-finding format, generic feature format, GFF) is a file format used for describing genes and other features of DNA, RNA and protein sequences.
GFF Versions
The following versions of GFF exist:
General Feature Format Version 2, generally deprecated
Gene Transfer Format 2.2, a derivative used by Ensembl
Generic Feature Format Version 3
Genome Variation Format, with additional pragmas and attributes for sequence_alteration features
GFF2/GTF had a number of deficiencies, notably that it can only represent two-level feature hierarchies and thus cannot handle the three-level hierarchy of gene → transcript → exon. GFF3 addresses this and other deficiencies. For example, it supports arbitrarily many hierarchical levels, and gives specific meanings to certain tags in the attributes field.
The GTF is identical to GFF, version 2.
GFF general structure
All GFF formats (GFF2, GFF3 and GTF) are tab delimited with 9 fields per line. They all share the same structure for the first 7 fields, while differing in the content and format of the ninth field. Some field names have been changed in GFF3 to avoid confusion. For example, the "seqid" field was formerly referred to as "sequence", which may be confused with a nucleotide or amino acid chain. The general structure is as follows:
The 8th field: phase of CDS features
Simply put, CDS means "CoDing Sequence". The exact meaning of the term is defined by Sequence Ontology (SO). Accordi

https://en.wikipedia.org/wiki/Obstacle%20avoidance
|
In robotics, obstacle avoidance is the task of satisfying some control objective subject to non-intersection or non-collision position constraints. What is critical about obstacle avoidance concept in this area is the growing need of usage of unmanned aerial vehicles in urban areas for especially military applications where it can be very useful in city wars. Normally obstacle avoidance is considered to be distinct from path planning in that one is usually implemented as a reactive control law while the other involves the pre-computation of an obstacle-free path which a controller will then guide a robot along. With recent advanced in the autonomous vehicles sector, a good and dependable obstacle avoidance feature of a driverless platform is also required to have a robust obstacle detection module.
Reactive obstacle avoidance is a behavior based control strategy in a robot. It is a task similar to the navigation problem and produces a collision free motion.

https://en.wikipedia.org/wiki/Synaptotropic%20hypothesis
|
The synaptotropic hypothesis, also called the synaptotrophic hypothesis, is a neurobiological hypothesis of neuronal growth and synapse formation. The hypothesis was first formulated by J.E. Vaughn in 1988, and remains a focus of current research efforts. The synaptotropic hypothesis proposes that input from a presynaptic to a postsynaptic cell (and maturation of excitatory synaptic inputs) eventually can change the course of synapse formation at dendritic and axonal arbors. This synapse formation is required for the development of neuronal structure in the functioning brain.
Dendritic Arbor Development
Growth
Dendrites of central nervous system neurons grow by addition and retraction of thin branches. This process is highly dynamic. Only a small fraction of newly added branches are actually maintained to become long-lasting components of the arbor. This process suggests that the branches sample the environment to detect the appropriate cells with which to form synapses. As a result, the hypothesis predicts that growth will be directed into regions containing more presynaptic elements. This morphology can be stabilized by creating microtubule nucleation at the microtubules.
Synaptogenesis
The formation of new synapses begins with initial contact between cells via cell-cell adhesion. This contact often occurs between either axonal or dendritic filopodia, which are highly dynamic and rarely stabilize. Next, the adhesive contact is converted to a nascent synapse, which conta

https://en.wikipedia.org/wiki/Transponder%20%28aeronautics%29
|
A transponder (short for transmitter-responder and sometimes abbreviated to XPDR, XPNDR, TPDR or TP) is an electronic device that produces a response when it receives a radio-frequency interrogation. Aircraft have transponders to assist in identifying them on air traffic control radar. Collision avoidance systems have been developed to use transponder transmissions as a means of detecting aircraft at risk of colliding with each other.
Air traffic control units use the term "squawk" when they are assigning an aircraft a transponder code, e.g., "Squawk 7421". Squawk thus can be said to mean "select transponder code" or "squawking xxxx" to mean "I have selected transponder code xxxx".
The transponder receives interrogation from the Secondary Surveillance Radar on 1030 MHz and replies on 1090 MHz.
Secondary surveillance radar
Secondary surveillance radar (SSR) is referred to as "secondary", to distinguish it from the "primary radar" that works by passively reflecting a radio signal off the skin of the aircraft. Primary radar determines range and bearing to a target with reasonably high fidelity, but it cannot determine target elevation (altitude) reliably except at close range. SSR uses an active transponder (beacon) to transmit a response to an interrogation by a secondary radar. This response most often includes the aircraft's pressure altitude and a 4-digit octal identifier.
Operation
A pilot may be requested to squawk a given code by an air traffic controller, via the

https://en.wikipedia.org/wiki/Beta-binomial%20distribution
|
In probability theory and statistics, the beta-binomial distribution is a family of discrete probability distributions on a finite support of non-negative integers arising when the probability of success in each of a fixed or known number of Bernoulli trials is either unknown or random. The beta-binomial distribution is the binomial distribution in which the probability of success at each of n trials is not fixed but randomly drawn from a beta distribution. It is frequently used in Bayesian statistics, empirical Bayes methods and classical statistics to capture overdispersion in binomial type distributed data.
The beta-binomial is a one-dimensional version of the Dirichlet-multinomial distribution as the binomial and beta distributions are univariate versions of the multinomial and Dirichlet distributions respectively. The special case where α and β are integers is also known as the negative hypergeometric distribution.
Motivation and derivation
As a compound distribution
The Beta distribution is a conjugate distribution of the binomial distribution. This fact leads to an analytically tractable compound distribution where one can think of the parameter in the binomial distribution as being randomly drawn from a beta distribution.
Suppose we were interested in predicting the number of heads, in future trials. This is given by
Using the properties of the beta function, this can alternatively be written

|
The Aberth method, or Aberth–Ehrlich method or Ehrlich–Aberth method, named after Oliver Aberth and Louis W. Ehrlich, is a root-finding algorithm developed in 1967 for simultaneous approximation of all the roots of a univariate polynomial.
This method converges cubically, an improvement over the Durand–Kerner method, another algorithm for approximating all roots at once, which converges quadratically. (However, both algorithms converge linearly at multiple zeros.)
This method is used in MPSolve, which is the reference software for approximating all roots of a polynomial to an arbitrary precision.
Description
Let be a univariate polynomial of degree with real or complex coefficients. Then there exist complex numbers , the roots of , that give the factorization:
Although those numbers are unknown, upper and lower bounds for their absolute values are computable from the coefficients of the polynomial. Now one can pick distinct numbers in the complex plane—randomly or evenly distributed—such that their absolute values are within the same bounds. (Also, if the zeros are symmetrical, the starting points must not be exactly symmetrical along the same axis, as this can prevent convergence.) A set of such numbers is called an initial approximation of the set of roots of . This approximation can be iteratively improved using the following procedure.
Let be the current approximations of the zeros of . Then offset numbers are computed as

Henry Bollmann Condy (8 July 1826 — 24 September 1907) was an English chemist and industrialist best noted for giving his name to the popular 19th and 20th century disinfectants Condy's Crystals and Condy's Fluid.
Condy was born in London. His mother inherited a chemical factory in Battersea from a Hungarian chemist named Dr Bollmann. A company was eventually set up in London that was known variously as Bollmann Condy and Co., Condy and Co., Condy Brothers and Co., Condy's Fluid Co., and Condy and Mitchell Ltd. The company began as a firm of vinegar manufacturers and drysalters. It later moved into essential oil, vitriol and disinfectant production. Condy became a partner in the company in 1854.
Condy had an interest in disinfectants and marketed products such as "ozonised water". He developed and patented "Condy's fluid" in 1857. Condy’s fluid was a disinfectant solution of alkaline manganates and permanganates that could be taken internally or used externally. It had various indications including the treatment and prevention of scarlet fever. A more stable crystalline version of Condy's fluid was subsequently developed and marketed as Condy's Crystals or Cond's powder. The fluid and crystals were both manufactured at the company’s works in Battersea between 1867 and 1897. The factory was taken over by Morgan Crucible.
He died in Folkestone, Kent.

https://en.wikipedia.org/wiki/Avrami%20equation
|
The Avrami equation describes how solids transform from one phase to another at constant temperature. It can specifically describe the kinetics of crystallisation, can be applied generally to other changes of phase in materials, like chemical reaction rates, and can even be meaningful in analyses of ecological systems.
The equation is also known as the Johnson–Mehl–Avrami–Kolmogorov (JMAK) equation. The equation was first derived by Johnson, Mehl, Avrami and Kolmogorov (in Russian) in a series of articles published in the Journal of Chemical Physics between 1939 and 1941. Moreover, Kolmogorov treated statistically the crystallization of a solid in 1937 (in Russian, Kolmogorov, A. N., Izv. Akad. Nauk. SSSR., 1937, 3, 355).
Transformation kinetics
Transformations are often seen to follow a characteristic s-shaped, or sigmoidal, profile where the transformation rates are low at the beginning and the end of the transformation but rapid in between.
The initial slow rate can be attributed to the time required for a significant number of nuclei of the new phase to form and begin growing. During the intermediate period the transformation is rapid as the nuclei grow into particles and consume the old phase while nuclei continue to form in the remaining parent phase.
Once the transformation approaches completion, there remains little untransformed material for further nucleation, and the production of new particles begins to slow. Additionally, the previously formed particles be

https://en.wikipedia.org/wiki/Permissiveness%20%28biology%29
|
In endocrinology, permissiveness is a biochemical phenomenon in which the presence of one hormone is required in order for another hormone to exert its full effects on a target cell. Hormones can interact in permissive, synergistic, or antagonistic ways. The chemical classes of hormones include amines, polypeptides, glycoproteins and steroids. Permissive hormones act as precursors to active hormones and may be classified as either prohormones or prehormones. It stimulate the formation of receptors of that hormone.
Examples
Thyroid hormone increases the number of beta adrenergic receptors available for epinephrine at the latter's target cell, thereby increasing epinephrine's effect on that cell. Specially in cardiac cell. Without the thyroid hormone, epinephrine would have only a weak effect.
Cortisol exerts a permissive effect on growth hormone.
The effects of a hormone in the body depend on its concentration. Permissive actions of glucocorticoids like cortisol generally occur at low concentrations. Abnormally high amounts of a hormone can result in atypical effects. Glucocorticoids function by attaching to cytoplasmic receptors to either enhance or suppress changes in the transcription of DNA and thus the synthesis of proteins. Glucocorticoids also inhibit the secretion of cytokines via post-translational modification effects.

The R600A Metox, named after its manufacturer, was a pioneering high-frequency radar warning receiver (RWR) used by the German forces on U-boats from 1942-45. It was initially installed to receive signals used by British radars.
Manufacture and purpose
The Metox was manufactured by a small French company in occupied Paris. It was tuned to receive the signals used by many British radars of the early and mid-World War II era, notably the ASV Mk. II radar used by RAF Coastal Command to attack U-boats. It is not clear whether the design was German or French or both. It was installed on German U-boats starting in 1942 and used until the end of the war. The system given the official title of FuMB 1 (for , Radio measuring device).
British radar
From July 1940, the British fitted the RAF Mk II AI (Airborne Interception) radar into Coastal Command aircraft for use as the Mk II "-metre ASV". The radar's known AI weaknesses — problems due to land clutter and inability to determine height, which caused its failure in night fighters — were no handicap in this new role. With two range scales, and , it could detect surfaced U-boats at up to and land at up to away, though a typical U-boat detection range was . The radar had a fairly crude display but was able to give the range and an approximate direction within an arc either side of the aircraft heading. Returns were lost in sea clutter once the aircraft was within about of the U-boat but usually by then, the aircraft was within vi

https://en.wikipedia.org/wiki/RAG1
|
Recombination activating gene 1 also known as RAG-1 is a protein that in humans is encoded by the RAG1 gene.
The RAG1 and RAG2 genes are largely conserved in humans. 55.99% and 55.98% of the encoded amino acids contain no reported variants, respectively.
Function
The protein encoded by this gene is involved in antibody and T-cell receptor V(D)J recombination. RAG-1 is involved in recognition of the DNA substrate, but stable binding and cleavage activity also requires RAG-2. The RAG-1/2 complex recognizes recombination signal sequences (RSSs) that flank the V, D and J regions in the genes that encode the heavy and light chains of antibodies and components of T-cell receptors. The complex binds to the RSSs and nicks the DNA. This leads to the removal of the intervening DNA and the eventual ligation of the V, D and J sequences. Defects in this gene can cause several different diseases.
Clinical significance
Because of these effects, Rag1 deletion is used in mouse models of disease to impair T cell and B cell development, and functionally deletes mature T and B cells from the immune system.
In humans, RAG deficiency was first recognised as a form of immune dysregulation known as Omenn syndrome. RAG deficiency is considered an autosomal recessive disease. The disorder is generally identified in infants. Complete loss-of-function in RAG1/2, the main components responsible for V(D)J recombination activity, produces severe immunodeficiency in humans.

MTD (Swedish abbreviation for Mobiltelefonisystem D, or Mobile telephony system D) was a manual mobile phone system for the 450 MHz frequency band. It was introduced in 1971 in Sweden, and lasted until 1987, when it was made obsolete by the NMT automatic service. The MTD network had 20,000 users at its peak, with 700 people employed as phone operators.
MTD was also implemented in Denmark and in Norway (from 1976), which allowed roaming within the Scandinavian countries.
MTA
In Sweden, the first mobile phone system was MTA (for Mobiltelefonisystem A), which was introduced in 1956, and lasted until 1967. It was a 160 MHz system available in Stockholm and Gothenburg, with 125 total subscribers. The second system, MTB (for Mobiltelefonisystem B), had transistorized mobile sets, was introduced in 1962, and lasted until 1983. It operated in the 76–77.5 and 81–82.5 MHz bands, was also available in Malmö, and had around 600 subscribers.
OLT
In Norway, the first mobile phone system was OLT, introduced in 1966. In 1976, the OLT system was extended to include UHF bands, incorporating MTD, and allowing international roaming within Sweden.

https://en.wikipedia.org/wiki/RAG2
|
Recombination activating gene 2 protein (also known as RAG-2) is a lymphocyte-specific protein encoded by RAG2 gene on human chromosome 11. Together with RAG1 protein, RAG2 forms a V(D)J recombinase, a protein complex required for the process of V(D)J recombination during which the variable regions of immunoglobulin and T cell receptor genes are assembled in developing B and T lymphocytes. Therefore, RAG2 is essential for generation of mature B and T lymphocytes.
Structure
RAG2 is a 527-amino acid long protein. Its N-terminal part is thought to form a six-bladed propeller in the active core. RAG2 is conserved among all species that carry out V(D)J recombination and its expression pattern correlates precisely with V(D)J recombinase activity. RAG2 is expressed in immature lymphoid cells. While amount of RAG1 is constant during the cell cycle, RAG2 accumulates mainly in G0 and G1 phase of cell cycle and it undergoes rapid degradation when the cell enters S phase. This serves as an important regulatory mechanism of V(D)J recombination and a prevention of genomic instability.
Function
RAG2 is one of the two core components of the RAG complex. RAG complex is a multiprotein complex that mediates the DNA cleavage phase during V(D)J recombination. This complex can make double-strand breaks by cleaving DNA at conserved recombination signal sequences (RSS).
The other core component of this complex is RAG1. This protein is thought to possess most of the catalytic activity of the RA

|
β-Hydroxy β-methylglutaryl-CoA (HMG-CoA), also known as 3-hydroxy-3-methylglutaryl coenzyme A, is an intermediate in the mevalonate and ketogenesis pathways. It is formed from acetyl CoA and acetoacetyl CoA by HMG-CoA synthase. The research of Minor J. Coon and Bimal Kumar Bachhawat in the 1950s at University of Illinois led to its discovery.
HMG-CoA is a metabolic intermediate in the metabolism of the branched-chain amino acids, which include leucine, isoleucine, and valine. Its immediate precursors are β-methylglutaconyl-CoA (MG-CoA) and β-hydroxy β-methylbutyryl-CoA (HMB-CoA).
HMG-CoA reductase catalyzes the conversion of HMG-CoA to mevalonic acid, a necessary step in the biosynthesis of cholesterol.
Biosynthesis
Mevalonate pathway
Mevalonate synthesis begins with the beta-ketothiolase-catalyzed Claisen condensation of two molecules of acetyl-CoA to produce acetoacetyl CoA. The following reaction involves the joining of acetyl-CoA and acetoacetyl-CoA to form HMG-CoA, a process catalyzed by HMG-CoA synthase.
In the final step of mevalonate biosynthesis, HMG-CoA reductase, an NADPH-dependent oxidoreductase, catalyzes the conversion of HMG-CoA into mevalonate, which is the primary regulatory point in this pathway. Mevalonate serves as the precursor to isoprenoid groups that are incorporated into a wide variety of end-products, including cholesterol in humans.
Ketogenesis pathway
HMG-CoA lyase breaks it into acetyl CoA and acetoacetate.

|
The RCA Type 77-DX microphone is a poly-directional ribbon microphone, or pressure-gradient microphone, introduced by the RCA Corporation in 1954. It was preceded by the Type 77-D introduced in 1948. Its popularity and classic design has resulted in the 77-DX becoming an iconic microphone, used by broadcasters and media personalities such as Edward R. Murrow, David Letterman and Larry King.
Controls
The directionality of the 77-DX is variable. A rotating backshutter on the acoustic labyrinth, controlled by a screwdriver-operated slot at the rear of the microphone, allows the user to vary the microphone's pattern from omnidirectional in the fully closed position, to cardioid, to figure-8 (bidirectional) in the fully open position. A 3-position switch at the bottom end of the microphone allows the user to control the amount of low-frequency rolloff.
Response and output characteristics
At 1 kHz, the 77-DX has an output of -50 to -56dbm, depending on the pattern selection. The output impedance is user-selectable; factory preset at 250 ohms, and changeable to 30 or 150 ohms. The microphone has a fairly flat response. In the cardioid (unidirectional) pattern, it is level from approximately 150 Hz to 2 kHz, with a slight rise peaking at just under 5 kHz, then dropping approximately 3 dB/octave to 20 kHz.
User techniques
The 77-DX has been used on countless vocal recordings by Bing Crosby, Kate Smith, Frank Sinatra, Elvis Presley, Johnny Cash, Al Green, and many others. It is stil

|
The RM class was the classification used by the New Zealand Railways Department (NZR) and its successors gave to most railcars and railbuses that have operated on New Zealand's national rail network. "RM" stands for Rail Motor which was the common name at the turn of the 20th century for what became known in New Zealand as railcars. As many types of railcars are operated, class names have been given to each railcar type to differentiate them from others.
Experimental and early railcars
In the early 20th century, NZR began investigating railcar technology to provide profitable and efficient passenger services on regional routes and rural branch lines where carriage trains were not economic and "mixed" trains (passenger carriage(s) attached to freight trains) were undesirably slow.
A number of experimental railcars and railbuses were developed:
1912: RM1 MacEwan-Pratt petrol railcar - the first railcar to operate in New Zealand
1914: RM1 (number re-used) Westinghouse petrol-electric railcar
1916: RM2 Thomas Transmission petrol-electric railcar
1924: A88 Buckhurst petrol carriage railcar (not officially a member of the RM class)
1925: Leyland petrol railcar
1925: RM4 and RM5 Model T Ford railbus
1925: Sentinel-Cammell steam railcar
1926: Clayton steam railcar

Detective Jimmy "Popeye" Doyle is a fictional character portrayed by actor Gene Hackman in the films The French Connection (1971) and its sequel, French Connection II (1975), and by Ed O'Neill in the 1986 television film Popeye Doyle. Hackman won the Academy Award for Best Actor for his performance in The French Connection. The character is based on a real-life New York City police detective, Eddie Egan, who also appeared in the film as Walt Simonson, Doyle's supervisor. Doyle, as played by Hackman in The French Connection, is ranked number 44 as a hero on the AFI's 100 Years...100 Heroes and Villains list.
The French Connection
In the 1971 movie The French Connection, Popeye is a rough police detective who routinely breaks the rules in an effort to catch criminals, in this case a group of French drug smugglers. On an individual basis, Popeye has many negative qualities; he is a racist, womanizing alcoholic who is often disrespectful to his superiors. Nevertheless, he is a dedicated officer leading the New York City Police Department's narcotics squad in drug arrests and is willing to do whatever it takes to lock up known drug dealers, even if it involves civilians. Near the end of the movie, Popeye accidentally kills Bill Mulderig (Bill Hickman), a federal agent with whom he previously had an argument. Undeterred by Mulderig's death, Popeye continues in pursuit of his foe.
French Connection II
The 1975 sequel French Connection II follows Popeye as he pursues drug smu

The Steel Helmet is a 1951 American war film directed, written, and produced by Samuel Fuller during the Korean War. The cast stars Gene Evans, Robert Hutton, Steve Brodie, James Edwards, and Richard Loo. It was the first American film about the war and the first of several war films by Fuller.
Plot
The opening credits roll on a U.S. Army steel helmet. There is a bullet hole on the left side. At last, it moves. The wearer peers out, then starts to inch his way up the steep grassy hill, past the bodies of other soldiers, holes in all their helmets. He moves on his side because his hands are tied behind him. He freezes at the approach of a barefoot boy with a gun, who listens to his heart, flips him over, cuts his bonds and pulls him to a sitting position. The sergeant rapidly takes salt and water and uses sulfa on the wound to his left knee. The boy gets more sulfa from one of the dead men.
The boy compliments him on his hard head, Removing the helmet and revealing a gouge on his scalp, Zack explains that the bullet went around the inside of his helmet and came out.
He is the only survivor of his unit, which was massacred in cold blood after surrendering to the enemy. Zack repays the South Korean youth by calling him a gook. An orphan, the child insists on following him, explaining: Buddha says that he who saves a man's life holds his heart in his hands. Zack tells him to get lost, but soon relents, dubbing him "Short Round", and telling him to get a helmet, a gun and

https://en.wikipedia.org/wiki/Fauna%20of%20Indonesia
|
The fauna of Indonesia is characterised by high levels of biodiversity and endemicity due to its distribution over a vast tropical archipelago. Indonesia divides into two ecological regions; western Indonesia which is more influenced by Asian fauna, and the east which is more influenced by Australasian species.
The Wallace Line, around which lies the Wallacea transitional region, notionally divides the two regions. There is diverse range of ecosystems, including beaches, sand dunes, estuaries, mangroves, coral reefs, sea grass beds, coastal mudflats, tidal flats, algal beds, and small island ecosystems.
Environmental issues due to Indonesia's rapid industrialisation process and high population growth, have seen lower priority given to preserving ecosystems. Issues include illegal logging, with resulting deforestation, and a high level of urbanisation, air pollution, garbage management and waste water services also contributing to the forest deterioration. The widespread deforestation and other environmental destruction in Indonesia has often been described by academics as an ecocide.
Origin of Indonesian fauna
The origin of fauna in Indonesia was determined by geographical and geological events on the Asian continental landmass and the Australasian continental landmass (now Australia). The island of New Guinea is connected with the present Australian continent, formerly as part of the southern supercontinent Gondwana.
This supercontinent began to break up 140 million yea

https://en.wikipedia.org/wiki/Sorting%20%28sediment%29
|
Sorting describes the distribution of grain size of sediments, either in unconsolidated deposits or in sedimentary rocks. This should not be confused with crystallite size, which refers to the individual size of a crystal in a solid. Crystallite is the building block of a grain. Very poorly sorted indicates that the sediment sizes are mixed (large variance); whereas well sorted indicates that the sediment sizes are similar (low variance).
The terms describing sorting in sediments – very poorly sorted, poorly sorted, moderately sorted, well sorted, very well sorted – have technical definitions and semi-quantitatively describe the amount of variance seen in particle sizes. See for details. In the field, sedimentologists use graphical charts to accurately describe the sorting of a sediment using one of these terms.
The degree of sorting may also indicate the energy, rate, and/or duration of deposition, as well as the transport process (river, debris flow, wind, glacier, etc.) responsible for laying down the sediment. Sorting of sediments can also be affected by reworking of the material after deposition, for instance, by winnowing.
Rocks derived from well sorted sediments are commonly both porous and permeable, while poorly sorted rocks have low porosity and low permeability, particularly when fine grained.

|
Subsurface lithoautotrophic microbial ecosystems, or "SLIMEs" (also abbreviated "SLMEs" or "SLiMEs"), are a type of endolithic ecosystems. They are defined by Edward O. Wilson as "unique assemblages of bacteria and fungi that occupy pores in the interlocking mineral grains of igneous rock beneath Earth's surface."
Endolithic systems are still at an early stage of exploration. In some cases its biota can support simple invertebrates, most organisms are unicellular. Near-surface layers of rock may contain blue-green algae but most energy comes from chemical synthesis of minerals. The limited supply of energy limits the rates of growth and reproduction. In deeper rock layers microbes are exposed to high pressures and temperatures.

|
The Wizard Knight is a series of epistolary novels written by fantasy and science fiction author Gene Wolfe. It chronicles the journey of Able of the High Heart, an American boy transported to a magical world and supernaturally aged to adulthood. Able (which is not his real name, but rather the name given to him) becomes a knight, and because of his connection with the magical and spiritual elements of the world around him is soon also dubbed a wizard.
Like many of Wolfe's writings, The Wizard Knight is characterized by a first person narrator – in this case, someone who tells events in fragmentary ways, out of order, and with omissions and connections that must be puzzled out later – though he is not an unreliable narrator.
The two volumes in the series are:
The Knight
The Wizard
Cosmology
The setting of the novel features elements from Norse, as well as Christian mythology and a smattering of European sources, such as Arthurian myth, and involves a seven-tiered world that is separate, but not completely detached, from ours.
The kingdom that Able is taken to is called Celidon, and lies in the middle world, Mythgarthr. The world above it, Skai, is the domain of the Overcyns, who are roughly analogous to the Æsir of Norse mythology, and to whom the inhabitants of Mythgarthr properly owe fealty. Terrible giants called "The Giants of Winter and Old Night", also dwell there, and are their foes. Above Skai is Kleos, which, being far from Mythgarthr, is not much explaine

https://en.wikipedia.org/wiki/Single-carrier%20FDMA
|
Single-carrier FDMA (SC-FDMA) is a frequency-division multiple access scheme. Originally known as Carrier Interferometry, it is also called linearly precoded OFDMA (LP-OFDMA). Like other multiple access schemes (TDMA, FDMA, CDMA, OFDMA), it deals with the assignment of multiple users to a shared communication resource. SC-FDMA can be interpreted as a linearly precoded OFDMA scheme, in the sense that it has an additional DFT processing step preceding the conventional OFDMA processing.
SC-FDMA has drawn great attention as an attractive alternative to OFDMA, especially in the uplink communications where lower peak-to-average power ratio (PAPR) greatly benefits the mobile terminal in terms of transmit power efficiency and reduced cost of the power amplifier. It has been adopted as the uplink multiple access scheme in 3GPP Long Term Evolution (LTE), or Evolved UTRA (E-UTRA).
The performance of SC-FDMA in relation to OFDMA has been the subject of various studies. Although the performance gap is small, SC-FDMA's advantage of low PAPR makes it desirable for uplink wireless transmission in mobile communication systems, where transmitter power efficiency is of paramount importance.
Transmitter and receiver structure
The transmission processing of SC-FDMA is very similar to that of OFDMA. For each user, the sequence of bits transmitted is mapped to a complex constellation of symbols (BPSK, QPSK, or M-QAM). Then different transmitters (users) are assigned different Fourier coefficie

https://en.wikipedia.org/wiki/Cryptophyceae
|
The cryptophyceae are a class of algae, most of which have plastids. About 220 species are known, and they are common in freshwater, and also occur in marine and brackish habitats. Each cell is around 10–50 μm in size and flattened in shape, with an anterior groove or pocket. At the edge of the pocket there are typically two slightly unequal flagella.
Some exhibit mixotrophy.
Characteristics
Cryptophytes are distinguished by the presence of characteristic extrusomes called ejectosomes or ejectisomes, which consist of two connected spiral ribbons held under tension. If the cells are irritated either by mechanical, chemical or light stress, they discharge, propelling the cell in a zig-zag course away from the disturbance. Large ejectosomes, visible under the light microscope, are associated with the pocket; smaller ones occur underneath the periplast, the cryptophyte-specific cell surrounding.
Except for Chilomonas, which has leucoplasts, cryptophytes have one or two chloroplasts. These contain chlorophylls a and c, together with phycobiliproteins and other pigments, and vary in color (brown, red to blueish-green). Each is surrounded by four membranes, and there is a reduced cell nucleus called a nucleomorph between the middle two. This indicates that the plastid was derived from a eukaryotic symbiont, shown by genetic studies to have been a red alga. However, the plastids are very different from red algal plastids: phycobiliproteins are present but only in the thylakoid lu

https://en.wikipedia.org/wiki/Chinese%20Water%20Torture%20Cell
|
The Chinese Water Torture Cell is a predicament escape made famous by Hungarian-American magician Harry Houdini. The illusion consists of three parts: first, the magician's feet are locked in stocks; next, he is suspended in mid-air from his ankles with a restraint brace; finally, he is lowered into a glass tank overflowing with water and the restraint is locked to the top of the cell.
History
The original Chinese Water Torture Cell was built in England in 1911. Houdini first performed the escape for an audience of one person as part of a one-act play he called Houdini Upside Down!. This was so he could copyright the new escape (having learned with his Milk Can escape that patents failed to stop imitators). The first public performance was at the Circus Busch in Berlin, Germany, on September 21, 1912. In letters Houdini referred to the effect as "the Upside Down" or "USD". Houdini continued to perform the escape until his death in 1926. Despite two Hollywood movies depicting Houdini dying in the Torture Cell, the escape had nothing to do with his demise.
After Houdini's death, the cell was willed to his brother Theodore Hardeen. Hardeen never performed the cell himself, and despite Houdini's instructions for it to be "burned and destroyed" upon Hardeen's death, his brother gave the cell to Houdini collector Sidney Hollis Radner in the 1940s. The cell remained in Radner's basement until 1971 when it was put on display at The Houdini Magical Hall of Fame in Niagara Falls, Can

Jeffrey Howard Dinitz (born 1952) is an American mathematician who taught combinatorics at the University of Vermont. He is best known for proposing the Dinitz conjecture, which became a major theorem.
Early life and education
Dinitz was born in 1952 in Brooklyn, New York City, New York.
XFL scheduling
Dinitz is also well known for scheduling the first season of the now-defunct XFL football league. He and a colleague from the Czech Republic, Dalibor Froncek, offered the then-brand-new XFL league their expertise to draft complicated schedules.
The XFL administration quickly agreed, which "surprised" Dinitz greatly. After some time on the computer, Dinitz and Froncek sent the XFL a draft schedule, and the new league gratefully accepted. Although the XFL folded after only one season, Dinitz was happy that "(he and Froncek) got to go to the championship game in Los Angeles".
Personal life
Dinitz is married to Susan Dinitz and has three children, Mike, Amy, and Tom.

https://en.wikipedia.org/wiki/Analbuminaemia
|
Analbuminaemia or analbuminemia is a rare genetically inherited metabolic defect characterised by an impaired synthesis of serum albumin. Although albumin is the most common serum protein, analbuminaemia is a benign condition.
Signs and symptoms
Analbuminaemia often presents in adulthood, with benign clinical features, such as mild oedema, low blood pressure and fatigue. Some patients may develop more serious symptoms such as lower body lipodystrophy. Severe hypercholesterolemia with increased serum low-density lipoprotein-cholesterol concentration and increased esterified cholesterol are often observed. Free fatty acids and raised apolipoprotein B may occur as well as increased serum high-density lipoprotein-3 and apolipoprotein A-I and A-II levels.

Phalanger is a compiler front end for compiling PHP source code into CIL byte-code, which can be further processed by the .NET Framework's just-in-time compiler. The project was started at Charles University and is supported by Microsoft. Phalanger was discontinued in favor of the more modern PeachPie compiler, which utilizes the Roslyn API.
Compatibility
Phalanger can run real-world PHP applications, many with minor to no modifications. Examples include WordPress, phpMyAdmin and phpBB.
Performance
One of the main goals of the project is to improve performance of PHP applications. The project web page claims considerable performance benefits over a 32-bit Windows version of PHP.
There was a project at Charles University to re-implement the Phalanger core using the Microsoft Dynamic Language Runtime (DLR), and to develop a Visual Studio integration tool to provide IntelliSense for the PHP language.
Though some features from DLR would slow down the performance of Phalanger, they do claim performance gains by a factor of 6. These features are being integrated into current Phalanger core.

https://en.wikipedia.org/wiki/TIM/TOM%20complex
|
The TIM/TOM complex is a protein complex in cellular biochemistry which translocates proteins produced from nuclear DNA through the mitochondrial membrane for use in oxidative phosphorylation. In enzymology, the complex is described as an mitochondrial protein-transporting ATPase (), or more systematically ATP phosphohydrolase (mitochondrial protein-importing), as the TIM part requires ATP hydrolysis to work.
Only 13 proteins necessary for a mitochondrion are actually coded in mitochondrial DNA. The vast majority of proteins destined for the mitochondria are encoded in the nucleus and synthesised in the cytoplasm. These are tagged by an N-terminal or/and a C-terminal signal sequence. Following transport through the cytosol from the nucleus, the signal sequence is recognized by a receptor protein in the translocase of the outer membrane (TOM) complex. The signal sequence and adjacent portions of the polypeptide chain are inserted in the TOM complex, then begin interaction with a translocase of the inner membrane (TIM) complex, which are hypothesized to be transiently linked at sites of close contact between the two membranes. The signal sequence is then translocated into the matrix in a process that requires an electrochemical hydrogen ion gradient across the inner membrane. Mitochondrial Hsp70 binds to regions of the polypeptide chain and maintains it in an unfolded state as it moves into the matrix.
The ATPase domain is essential during the interactions of the protein

https://en.wikipedia.org/wiki/Cytohet
|
In genetics, a cytohet (or heteroplasmon) is a eukaryotic cell whose non-nuclear genome is heterozygous.
The non-nucleic genome of eukaryotic cells exists in cytoplasmic organelles, namely the chloroplasts (only in plant cells) and the mitochondria (in all eukaryotic cells).
Most of the genes in the mitochondria code for respiration-related proteins, and most of the genes in the chloroplasts code for photosynthesis-related proteins. The cytoplasmic genome, in contrast with the nucleic genome, exists in many copies in each cell: each cell contains numerous mitochondria and/or chloroplasts, and each such organelle contains multiple copies of its chromosome.
Mutations in the cytoplasmic genome occur spontaneously and at a much higher rate than in the nucleus, since the mitochondria and chloroplasts are exposed to high concentrations of reactive oxygen species (ROS, by-products of respiration and photosynthesis). Mitochondria and chloroplasts with mutant genes have the ability to cause wildtype alleles in other mitochondria and chloroplasts to become mutant as well; the way in which this is done is still not clear. A certain cell in which a mutant gene exists only in some of the organelles, whereas the wildtype allele exists in the rest, is a cytohet (or heteroplasmon).

Haplogroup C-M217, also known as C2 (and previously as C3), is a Y-chromosome DNA haplogroup. It is the most frequently occurring branch of the wider Haplogroup C (M130). It is found mostly in Central Asia, Eastern Siberia and significant frequencies in parts of East Asia and Southeast Asia including some populations in the Caucasus, Middle East, South Asia, East Europe. It is found in a much more widespread areas with a low frequency of less than 2%.
The haplogroup C-M217 is now found at high frequencies among Central Asian peoples, indigenous Siberians, and some Native peoples of North America. In particular, males belonging to peoples such as the Buryats, Evens, Evenks, Itelmens, Kalmyks, Kazakhs, Koryaks, Mongolians, Negidals, Nivkhs, Udege, and Ulchi have high levels of M217.
One particular haplotype within Haplogroup C2-M217 has received a great deal of attention, because of the possibility that it may represent direct patrilineal descent from Genghis Khan, though that hypothesis is controversial. According to the recent result, C2's subgroups are divided into C2b and C2e, and in Mongolia, most belong to C2b(Genghis Khan modal), while very few are C2e. On the other hand, C2b takes minority and most are C2e in Japan and Korea and Southern East Asia.

https://en.wikipedia.org/wiki/Sesamol
|
Sesamol is a natural organic compound which is a component of sesame seeds and sesame oil, with anti-inflammatory, antioxidant, antidepressant and neuroprotective properties. It is a white crystalline solid that is a derivative of phenol. It is sparingly soluble in water, but miscible with most oils. It can be produced by organic synthesis from heliotropine.
Sesamol has been found to be an antioxidant that may prevent the spoilage of oils. It also may prevent the spoilage of oils by acting as an antifungal. It can be used in the synthesis of paroxetine.
Sesamol's molecular targets and mechanism of action, at least for its antidepressant-like effects, is found to be through the brain nerve growth factor (NGF) and endocannabinoid signalling under the regulatory drive of the CB1 receptors.
Alexander Shulgin used sesamol in his book PiHKAL to make MMDA-2.

WPXZ-FM is a commercial FM radio station licensed to Punxsutawney, Pennsylvania, known as the "Weather Capital of the World". The station operates at a federally assigned frequency of 104.1 MHz and an effective radiated power of 3,000 watts. WPXZ, and its co-located sister stations, WECZ and WKQL, are all owned by Pittsburgh-based Renda Broadcasting Corporation.
WPME-FM Punxsutawney, a "shadow" of its AM sister
Signing on at 105.5 MHz, WPXZ originated in December 1973 as WPME-FM, simulcasting with its then same-named daytime-only AM sister station, known today as WECZ. The stations were owned by the Punxsutawney Broadcasting Company, headed by Clearfield County native and Punxsutawney resident Charles M. "Charlie" Erhard Jr. (April 30, 1928 - July 12, 2004), who sold the stations to its present owner in 1981.
That year, the station pair would both be rebranded as WPXZ-AM-FM, continuing with simulcasting until 1989, when management finally began separate broadcasts. Seeing the FM station as the driving force of the two, the AM station would be rebranded under the WECZ call sign.
While WECZ would adopt a format featuring big band, swing, and other types of nostalgia music aimed at an older demographic and branded as "Easy 1540," WPXZ-FM continued operating under an adult contemporary format, albeit with a full-service mindset. In addition to its music, the station's programming featured hourly national news from ABC News Radio, high school sports, Pittsburgh Pirates baseba

The Chevrolet Sequel is a purpose-built hydrogen fuel cell-powered concept car and sport utility vehicle from Chevrolet, employing the then latest generation of General Motors' fuel cell technology.
The Sequel's powertrain includes an electronic control unit and a fourth-generation version of GM's fuel-cell stack. The Sequel became the basis for the design of the gas-powered Chevrolet Traverse, which was the replacement for the Uplander minivan.
Characteristics
The Sequel's fuel-cell stack has a rated power output of , supplemented by a lithium-ion battery pack rated at . One electric motor drives the front wheels, and individual wheel-motors (outboard of the rear brakes) drive each rear wheel, providing total tractive power of .
The Sequel stores of gaseous hydrogen in three cylindrical, carbon-composite fuel tanks, pressurized to and mounted longitudinally beneath the cabin floor. As a result, the range of the vehicle is more than .
The Sequel is just short of five metres long (4,994 mm, 196.1 in.), on a similarly long (3,040 mm, 119.7 in.) wheelbase in order to accommodate the extremely long fuel tanks.
Possible production
GM made no commitment to building the Sequel. However, GM vice-chairman Bob Lutz has said he would push the company's strategy board to approve full production of a fuel-cell vehicle by 2011 model year. Due to the extremely high cost of fuel cells, GM opted to instead build several hydrogen-powered Chevrolet Equinox-based vehicles as testbeds. I

https://en.wikipedia.org/wiki/Dynamic%20frequency%20selection
|
Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LAN, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar, satellite communication, and weather radar, and also to provide on aggregate a near-uniform loading of the spectrum (uniform spreading). It was standardized in 2003 as part of IEEE 802.11h.
Radar Detection Mechanism
When starting operation, an access point automatically selects channels with low interference levels in a phase known as Channel Availability Check (CAC). During this phase, the access point is in a passive state scanning for radar signals. This commonly takes one to two minutes, but could take up to ten minutes. Thereafter, the access point performs In-Service Monitoring (ISM) to detect active radar signals; if radar is detected, and the access point is configured to automatically select a channel, it broadcasts a switch-channel event to its clients and follows by switching the channel. If channels were configured manually, the DFS mechanism causes the access point to go offline.
The actual mechanism, durations, radar pulse pattern, power levels, and frequency bands on which DFS is enforced vary by jurisdiction. DFS is mandated for the 5470–5725 MHz U-NII band in United States by the FCC. DFS is mandatory for the 5250–5350 and 5470–5725 MHz bands in India.

https://en.wikipedia.org/wiki/Microsatellite%20instability
|
Microsatellite instability (MSI) is the condition of genetic hypermutability (predisposition to mutation) that results from impaired DNA mismatch repair (MMR). The presence of MSI represents phenotypic evidence that MMR is not functioning normally.
MMR corrects errors that spontaneously occur during DNA replication, such as single base mismatches or short insertions and deletions. The proteins involved in MMR correct polymerase errors by forming a complex that binds to the mismatched section of DNA, excises the error, and inserts the correct sequence in its place. Cells with abnormally functioning MMR are unable to correct errors that occur during DNA replication and consequently accumulate errors. This causes the creation of novel microsatellite fragments. Polymerase chain reaction-based assays can reveal these novel microsatellites and provide evidence for the presence of MSI.
Microsatellites are repeated sequences of DNA. These sequences can be made of units of 1 to 6 base pairs in length that are repeated and reside adjacent to each other in the genome. Although the length of microsatellites can vary from person to person and contributes to the individual DNA "fingerprint", each individual has microsatellites of a set length. The most common microsatellite in humans is a dinucleotide repeat of the nucleotides C and A, which occurs tens of thousands of times across the genome. Microsatellites are also known as simple sequence repeats (SSRs).

Sir Frederick Charles Frank, OBE, FRS (6 March 1911 – 5 April 1998) was a British theoretical physicist. He is best known for his work on crystal dislocations, including (with Thornton Read) the idea of the Frank–Read source of dislocations. He also proposed the cyclol reaction in the mid-1930s, and made many other contributions to solid-state physics, geophysics, and the theory of liquid crystals.
Early life and education
He was born in Durban, South Africa, although his parents returned to England soon afterwards. He was educated at Thetford Grammar School and Ipswich School and went on to study chemistry at Lincoln College, Oxford, gaining a doctorate at the university's Engineering Laboratory.
Career
Prior to World War II, he worked as a physicist in Berlin and as a colloid chemist in Cambridge. During World War II he joined the Chemical Defence Experimental Station at Porton Down, Wiltshire, but in 1940 was transferred to the Air Ministry's Assistant Directorate of Intelligence (Science) and spent the rest of the war with the Air Ministry. Due to his work he was made Officer of the Most Excellent Order of the British Empire in 1946.
After the war he moved to the University of Bristol Physics Department to do research in solid state physics, but switched to research on crystal dislocation. His work with William Keith Burton and Nicolás Cabrera was to demonstrate the role dislocations played in the growth of crystals.

https://en.wikipedia.org/wiki/Sequential%20quadratic%20programming
|
Sequential quadratic programming (SQP) is an iterative method for constrained nonlinear optimization which may be considered a quasi-Newton method. SQP methods are used on mathematical problems for which the objective function and the constraints are twice continuously differentiable.
SQP methods solve a sequence of optimization subproblems, each of which optimizes a quadratic model of the objective subject to a linearization of the constraints. If the problem is unconstrained, then the method reduces to Newton's method for finding a point where the gradient of the objective vanishes. If the problem has only equality constraints, then the method is equivalent to applying Newton's method to the first-order optimality conditions, or Karush–Kuhn–Tucker conditions, of the problem.
Algorithm basics
Consider a nonlinear programming problem of the form:
The Lagrangian for this problem is
where and are Lagrange multipliers.
The standard Newton's Method searches for the solution by iterating the following equation, where denotes the Hessian matrix:
.
However, because the matrix is generally singular (and therefore non-invertible), the Newton step cannot be calculated directly. Instead the basic sequential quadratic programming algorithm defines an appropriate search direction at an iterate , as a solution to the quadratic programming subproblem

{{DISPLAYTITLE:conio.h}}
conio.h is a C header file used mostly by MS-DOS compilers to provide console input/output. It is not part of the C standard library or ISO C, nor is it defined by POSIX.
This header declares several useful library functions for performing "istream input and output" from a program. Most C compilers that target DOS, Windows 3.x, Phar Lap, DOSX, OS/2, or Win32 have this header and supply the associated library functions in the default C library. Most C compilers that target UNIX and Linux do not have this header and do not supply the library functions. Some embedded systems or cc65 use a conio-compatible library.
The library functions declared by vary somewhat from compiler to compiler. As originally implemented in Lattice C, the various functions mapped directly to the first few DOS INT 21H functions. The library supplied with Borland's Turbo C did not use the DOS API but instead accessed video RAM directly for output and used BIOS interrupt calls. This library also has additional functions inspired from the successful Turbo Pascal one.
Compilers that target non-DOS operating systems, such as Linux or OS/2, provide similar solutions; the unix-related curses library is very common here. Another example is SyncTERM's ciolib. The version of done by DJ Delorie for the GO32 extender is particularly extensive.

https://en.wikipedia.org/wiki/Candidatus%20Carsonella%20ruddii
|
"Candidatus Carsonella ruddii" is an obligate endosymbiotic Gammaproteobacterium with one of the smallest genomes of any characterised bacteria.
This is the first, and as of February 2022 the only species described from the genus Candidatus Carsonella, named after Rachel Carson.
Endosymbiosis
The species is an endosymbiont that is present in all species of phloem sap-feeding insects known as psyllids. The endosymbionts occurs in a specialised structure known as the bacteriome.
C. ruddii is not completely parasitic in its relationship with its host insect; it supplies the host with some essential amino acids. It is therefore probably in the evolutionary process of becoming an organelle, similar to the mitochondria of eukaryotic cells that also evolved from an endosymbiont.
Genome
In 2006 the genome of Ca. C. ruddii strain Pv (Carsonella-Pv) of the hackberry petiole gall psyllid, Pachypsylla venusta, was sequenced at RIKEN in Japan and the University of Arizona. It was shown that the genome consists of a circular chromosome of 159,662 base pairs and that it has a high coding density (97%) with many overlapping genes and reduced gene length. The number of predicted genes was 182, also the lowest on record (NCBI-Genome). In comparison, Mycoplasma genitalium, which has the smallest genome of any free-living organism, has a genome of 521 genes. Numerous genes considered essential for life seem to be missing, suggesting that the species may have achieved organelle-like status.

https://en.wikipedia.org/wiki/Constraint%20%28mathematics%29
|
In mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. There are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. The set of candidate solutions that satisfy all constraints is called the feasible set.
Example
The following is a simple optimization problem:
subject to
and
where denotes the vector (x1, x2).
In this example, the first line defines the function to be minimized (called the objective function, loss function, or cost function). The second and third lines define two constraints, the first of which is an inequality constraint and the second of which is an equality constraint. These two constraints are hard constraints, meaning that it is required that they be satisfied; they define the feasible set of candidate solutions.
Without the constraints, the solution would be (0,0), where has the lowest value. But this solution does not satisfy the constraints. The solution of the constrained optimization problem stated above is , which is the point with the smallest value of that satisfies the two constraints.
Terminology
If an inequality constraint holds with equality at the optimal point, the constraint is said to be , as the point cannot be varied in the direction of the constraint even though doing so would improve the value of the objective function.
If an inequality constraint holds as a strict inequality at the optimal point (that is, does not hol

https://en.wikipedia.org/wiki/Bucladesine
|
Bucladesine is a cyclic nucleotide derivative which mimics the action of endogenous cAMP and is a phosphodiesterase inhibitor.
Bucladesine is a cell permeable cAMP analog. The compound is used in a wide variety of research applications because it mimics cAMP and can induce normal physiological responses when added to cells in experimental conditions. cAMP is only able to elicit minimal responses in these situations.
The neurite outgrowth instigated by bucladesine in cell cultures has been shown to be enhanced by nardosinone.
Bucladesine and seizure
The effect of bucladesine as a cAMP analog has been studied on the pentylenetetrazol-induced seizure in the wild-type mice. The data showed that bucladesine (300nM/mouse) reduced the seizure latency and threshold. In addition they found that combination of bucladesine and pentoxyfillin has additive effect on seizure latency and threshold.
Bucladesine and morphine withdrawal syndrome
Bucladesine (50-100nM/mouse) showed significant attenuation in the morphine withdrawal syndrome in the wild-type mice. In addition, its high dose (200nM/mouse) combination with H-89, as a protein kinase inhibitor, had additive attenuating effect on withdrawal syndromes.

Red River Valley, later retitled Man of the Frontier for American television screening, is a 1936 American Western film directed by B. Reeves Eason and starring Gene Autry, Smiley Burnette, and Frances Grant. Written by Dorrell and Stuart E. McGowan, the film is about a "ditch rider" and his sidekick who set out to find out who has been causing the accidents at a dam construction site.
Plot
In Red River Valley, Banker Hartley Moore (Frank LaRue) schemes to sabotage the efforts of citizens to secure water rights in order to win water profits for himself. Following the murder of five men who were overseeing the completion of an irrigation system, Gene Autry (Gene Autry) is hired for the dangerous job of "ditch rider", in charge of patrolling the ditches to prevent malfunction or sabotage.
At the Red River Land and Irrigation Company, Steve Conway (Boothe Howard) works for Mary Baxter (Frances Grant) and her father, George Baxter (Sam Flint). Jealous of Mary's attention towards Gene, Conway joins Moore in his scheming actions and hires Bull Dural and his gang to dynamite the water gates and kill the ditch riders.
On his first night on the job, Gene and his friend Frog Millhouse (Smiley Burnette) are almost killed. They apprehend Bull's henchmen and turn them over to the sheriff. Conway and Bull then rob the payroll, accuse Gene of the crime, and encourage Baxter's workmen to revolt by destroying the dam. Gene and Frog go after Bull, while Baxter and the railroad conductor ho

Perceptual Audio Coder (PAC) is a lossy audio compression algorithm. It is used by Sirius Satellite Radio for their digital audio radio service.
Development
The original version of PAC developed by James Johnston and Anibal Ferreira at AT&T's Bell Labs has a flexible format and bitrate. It provides efficient compression of high-quality audio over a variety of formats from 16 kbit/s for a monophonic channel to 1024 kbit/s for a 5.1 format with four or six auxiliary audio channels, and provisions for an ancillary (fixed rate) and auxiliary (variable rate) side data channel. For stereo audio signals, it is claimed that it provides near-CD quality at about 56-64 kbit/s, with transparent coding at bit rates approaching 128 kbit/s.
Over the years PAC has evolved considerably. A known software implementation of this codec is CelestialTech's AudioLib. Later, it was considerably improved and renamed to ePAC (enhanced Perceptual Audio Coder) by Lucent, available in the AudioVeda music library manager.
iBiquity initially tested PAC for the HD-Radio IBOC digital radio upgrade for FM and AM, but chose an MPEG4-derived codec, HE-AAC, instead. MPEG-2 AAC is substantially similar to the original AT&T PAC algorithm written by Johnston and Ferreira, including the specifics of stereo pair coding, bitstream sectioning, handling of 1 or 2 channels at a time, multiple codebooks responding to the same largest absolute value, and block switching triggers.

https://en.wikipedia.org/wiki/Origin%20recognition%20complex
|
In molecular biology, origin recognition complex (ORC) is a multi-subunit DNA binding complex (6 subunits) that binds in all eukaryotes and archaea in an ATP-dependent manner to origins of replication. The subunits of this complex are encoded by the ORC1, ORC2, ORC3, ORC4, ORC5 and ORC6 genes. ORC is a central component for eukaryotic DNA replication, and remains bound to chromatin at replication origins throughout the cell cycle.
ORC directs DNA replication throughout the genome and is required for its initiation. ORC and Noc3p bound at replication origins serve as the foundation for assembly of the pre-replication complex (pre-RC), which includes Cdc6, Tah11 (a.k.a. Cdt1), and the Mcm2-Mcm7 complex. Pre-RC assembly during G1 is required for replication licensing of chromosomes prior to DNA synthesis during S phase. Cell cycle-regulated phosphorylation of Orc2, Orc6, Cdc6, and MCM by the cyclin-dependent protein kinase Cdc28 regulates initiation of DNA replication, including blocking reinitiation in G2/M phase.
The ORC is present throughout the cell cycle bound to replication origins, but is only active in late mitosis and early G1.
In yeast, ORC also plays a role in the establishment of silencing at the mating-type loci Hidden MAT Left (HML) and Hidden MAT Right (HMR). ORC participates in the assembly of transcriptionally silent chromatin at HML and HMR by recruiting the Sir1 silencing protein to the HML and HMR silencers.

Hinduism in Azerbaijan has been tied to cultural diffusion on the Silk Road. One of the remnants of once-dominant Hindu and Buddhist culture in the Caucasus is Surakhani, the site of the Ateshgah of Baku. As of 2020, there were about 500 Hindus in Azerbaijan.
History
In the Middle Ages, Hindu traders visited present-day Azerbaijan for Silk Road trade. The area was traversed by Hindu traders coming mostly from Multan and Sindh (in present-day Pakistan). The Atasghah in Surakhani was used by those traders to worship while in the area. Most of the traders left around the advent of the British Raj. The ceremonies were officiated by a Punjabi pandit. Historical sources indicate that locals worshipped at Surakhani even before the construction of the Atashgah, drawn by the "seven holes with burning flame" from which Surakhani takes its name. In the 1880s, the Czar Alexander III of Russia went to Azerbaijan to witness one of the last Hindu ceremonies performed there. After the 1890s, nearly all of the original Hindu merchants in Azerbaijan had died or left for The Indian Subcontinent.

The National Marrow Donor Program (NMDP) is a nonprofit organization founded in 1986 and based in Minneapolis, Minnesota, that operates the Be The Match Registry of volunteer hematopoietic cell donors and umbilical cord blood units in the United States.
The Be The Match Registry is the world's largest hematopoietic cell registry, listing more than 22 million individuals and more than 300,000 cord blood units. Hematopoietic cells from NMDP donors or cord blood units are used to transplant patients with a variety of blood, bone marrow or immune system disorders. As of December 2020, the NMDP had facilitated more than 100,000 transplants worldwide.
Activities
The NMDP coordinates the collection of hematopoietic ("blood-forming") cells that are used to perform what used to be called bone marrow transplants, but are now more properly called hematopoietic cell transplants. Patients needing a hematopoietic cell transplant but who lack a suitably matched donor in their family can search the Be The Match Registry for a matched unrelated donor or cord blood unit.
Hematopoietic cells are used to transplant patients with life-threatening disorders such as leukemia, lymphoma, aplastic anemia, as well as certain immune system and metabolic disorders. Hematopoietic cells can come from bone marrow, umbilical cord blood, or the circulating blood (peripheral blood stem cells (PBSCs)). Hematopoietic cells are a type of adult (i.e., non-embryonic) stem cell that can multiply and differentiat
