https://en.wikipedia.org/wiki/Alex%20Bavelas | Alexander Bavelas (December 26, 1913 – August 16, 1993) was an American psychosociologist credited as the first to define closeness centrality. His work was influential in using mathematics in developing the concept of
centralization and in formalizing fundamental concepts of network structure.
University of Iowa
As one of Kurt Lewin's first graduate students, Bavelas went to University of Iowa from Springfield College trained on group work. He suggested to Lewin a method of training people to be democratic, which would become the germ of extending autocracy-democracy studies to the field of industrial relations. At Lewin's suggestion, Bavelas sought to directly apply small group dynamics theory to labor-management relations by conducting small-group experiments at the Harwood Manufacturing Company in Virginia, known as Harwood research. In implementing a program of collaborative research in Harwood, he created and developed the `Echo approach' in the early 1940s. From 1940 to 1947, Bavelas and his successor John French were able to have many of Harwood's 600 workers and almost all of the managers in experiments. These proved to be successful in increasing worker productivity while maintaining good morale, and thus small-group research in industrial settings became Bavelas's forte.
Move to Massachusetts Institute of Technology
Bavelas moved with Lewin from Iowa to MIT. He also used the Echo approach in studying Mennonite children.
Working in MIT the 1940s and 1950s, Bavelas used mathematics to formalize his theories on social networks. After Lewin's death in 1947, Bavelas stayed in MIT while many of Lewin's students transferred to the University of Michigan to create a new Center for Group Dynamics. In 1948, Bavelas obtained his PhD from MIT with Some Mathematical Properties of Psychological Space as his doctoral thesis with Dorwin Cartwright as his adviser. Years later, Frank Harary told Cartwright that Bavelas' PhD thesis showed an independent rediscovery of graph theory. In the late 1940s, Bavelas worked in the Industrial Relations section of MIT's Department of Economics & Social Science, then headed by Douglas McGregor. He founded the Group Networks Laboratory at MIT in 1948, which included mathematician R. Duncan Luce and social psychologist Leon Festinger.
Bavelas experiments
Bavelas designed studies focused on information diffusion within a small group and on network structures that affect the speed and efficiency of this information diffusion. Bavelas and his students—particularly Harold Leavitt—conducted experiments on the effect of organizational structure on productivity and morale. In these experiments, small groups were given a task to complete, and then the communication structure was altered to determine if performance would be affected by a modification in the group structure.
These experiments would be known as the 'Bavelas experiments' and would be described as social psychology experiments using five-person groups with |

https://en.wikipedia.org/wiki/Intel%208231/8232 | The Intel 8231 and 8232 were early designs of floating-point maths coprocessors (FPUs), marketed for use with their i8080 line of primary CPUs. They were licensed versions of AMD's Am9511 and Am9512 FPUs, from 1977 and 1979, themselves claimed by AMD as the world's first single-chip FPU solutions.
Adoption
Whilst the i8231/i8232 (and their AMD-branded cousins) were primarily intended to partner the i8080 (or the AMD clone Am9080), the multiple interface options in their design, from simple wait state insertion and status polling routines to interrupt and DMA controller driven methods suitable for a peripheral processor or add-in board, meant that – with a small amount of glue logic – it was usable in almost any microprocessor system that had a DMA subsystem or a spare interrupt input/interrupt vector available, and AMD's original documentation provided several different examples. This was a valuable feature for one of the first commercially available single-chip FPUs, greatly broadening its potential market, and was in stark contrast to Intel's succeeding, in-house designed 8087 (and other x87 family) FPUs which were tightly bound to the x86 CPU line. For example, the i8231A was used in the Applied Analytics MicroSPEED II and II+ accelerator cards for the 6502-based Apple II line, but examples were also given for the Z80, MC6800, i8085, and even the 16-bit Z8000. Additionally, prior to the introduction of the 8087, Intel's own preliminary datasheets suggested the chips as suitable companions for the then-new 8086.
Capacity
The Intel 8231 (and revised 8231A) is the Arithmetic Processing Unit (APU). It offered 32-bit "double" precision (a term later and more commonly used to describe 64-bit floating-point numbers, whilst 32-bit is considered "single" precision) floating-point, and 16-bit or 32-bit ("single" or "double" precision) fixed-point calculation of 14 different arithmetic and trigonometric functions to a proprietary standard. The APU used the Chebyshev polynomials using the algorithms provided here. The available APU version of 4-MHz was for USD $235.00 and 2-MHz was for USD $149.00 in quantities of 100 or more. The later Intel 8232 is the Floating Point Processor Unit (FPU). It performed 32-bit or 64-bit (true single- and double-precision) floating point calculations compliant with the (draft) IEEE-754 standard (as used by the i80387 and other later FPUs), but only on the four primary arithmetic functions (addition, subtraction, multiplication and division). The available FPU version of 4-MHz was for USD $235.00 and 2-MHz was for USD $149.00 in quantities of 100 or more.
All three chips used an 8-bit data bus design, in line with the i8080 and most other contemporary microprocessors. The 8231 could run at up to 3 MHz, and the 8231A and 8232 up to 4 MHz (a slight improvement on the Am9512 which was limited to 3 MHz), either in sync with the CPU or (in the 8231A and 8232) asynchronously depending on the degree of bus separation in t |

https://en.wikipedia.org/wiki/Markov%20chain%20central%20limit%20theorem | In the mathematical theory of random processes, the Markov chain central limit theorem has a conclusion somewhat similar in form to that of the classic central limit theorem (CLT) of probability theory, but the quantity in the role taken by the variance in the classic CLT has a more complicated definition. See also the general form of Bienaymé's identity.
Statement
Suppose that:
the sequence of random elements of some set is a Markov chain that has a stationary probability distribution; and
the initial distribution of the process, i.e. the distribution of , is the stationary distribution, so that are identically distributed. In the classic central limit theorem these random variables would be assumed to be independent, but here we have only the weaker assumption that the process has the Markov property; and
is some (measurable) real-valued function for which
Now let
Then as we have
where the decorated arrow indicates convergence in distribution.
Monte Carlo Setting
The Markov chain central limit theorem can be guaranteed for functionals of general state space Markov chains under certain conditions. In particular, this can be done with a focus on Monte Carlo settings. An example of the application in a MCMC (Markov Chain Monte Carlo) setting is the following:
Consider a simple hard spheres model on a grid. Suppose . A proper configuration on consists of coloring each point either black or white in such a way that no two adjacent points are white. Let denote the set of all proper configurations on , be the total number of proper configurations and π be the uniform distribution on so that each proper configuration is equally likely. Suppose our goal is to calculate the typical number of white points in a proper configuration; that is, if is the number of white points in then we want the value of
If and are even moderately large then we will have to resort to an approximation to . Consider the following Markov chain on . Fix and set where is an arbitrary proper configuration. Randomly choose a point and independently draw . If and all of the adjacent points are black then color white leaving all other points alone. Otherwise, color black and leave all other points alone. Call the resulting configuration . Continuing in this fashion yields a Harris ergodic Markov chain having as its invariant distribution. It is now a simple matter to estimate with . Also, since is finite (albeit potentially large) it is well known that will converge exponentially fast to which implies that a CLT holds for .
Implications
Not taking into account the additional terms in the variance which stem from correlations (e.g. serial correlations in markov chain monte carlo simulations) can result in the problem of pseudoreplication when computing e.g. the confidence intervals for the sample mean.

https://en.wikipedia.org/wiki/Ordered%20exponential%20field | In mathematics, an ordered exponential field is an ordered field together with a function which generalises the idea of exponential functions on the ordered field of real numbers.
Definition
An exponential on an ordered field is a strictly increasing isomorphism of the additive group of onto the multiplicative group of positive elements of . The ordered field together with the additional function is called an ordered exponential field.
Examples
The canonical example for an ordered exponential field is the ordered field of real numbers R with any function of the form where is a real number greater than 1. One such function is the usual exponential function, that is . The ordered field R equipped with this function gives the ordered real exponential field, denoted by . It was proved in the 1990s that Rexp is model complete, a result known as Wilkie's theorem. This result, when combined with Khovanskiĭ's theorem on pfaffian functions, proves that Rexp is also o-minimal. Alfred Tarski posed the question of the decidability of Rexp and hence it is now known as Tarski's exponential function problem. It is known that if the real version of Schanuel's conjecture is true then Rexp is decidable.
The ordered field of surreal numbers admits an exponential which extends the exponential function exp on R. Since does not have the Archimedean property, this is an example of a non-Archimedean ordered exponential field.
The ordered field of logarithmic-exponential transseries is constructed specifically in a way such that it admits a canonical exponential.
Formally exponential fields
A formally exponential field, also called an exponentially closed field, is an ordered field that can be equipped with an exponential . For any formally exponential field , one can choose an exponential on such that
for some natural number .
Properties
Every ordered exponential field is root-closed, i.e., every positive element of has an -th root for all positive integer (or in other words the multiplicative group of positive elements of is divisible). This is so because for all .
Consequently, every ordered exponential field is a Euclidean field.
Consequently, every ordered exponential field is an ordered Pythagorean field.
Not every real-closed field is a formally exponential field, e.g., the field of real algebraic numbers does not admit an exponential. This is so because an exponential has to be of the form for some in every formally exponential subfield of the real numbers; however, is not algebraic if is algebraic by the Gelfond–Schneider theorem.
Consequently, the class of formally exponential fields is not an elementary class since the field of real numbers and the field of real algebraic numbers are elementarily equivalent structures.
The class of formally exponential fields is a pseudoelementary class. This is so since a field is exponentially closed if and only if there is a surjective function such that and ; and these properties |

https://en.wikipedia.org/wiki/Michael%20Roberts%20%28mathematician%29 | Michael Roberts (18 April 1817 – 4 October 1882), was an Irish mathematician and academic of Trinity College, Dublin (TCD), who served as Erasmus Smith's Professor of Mathematics there 1862-1879.
Life
Roberts was born into a well-established landed gentry family in County Cork, whose ancestors had settled there from Kent about 1630. His mother was of Scottish origins, descended from the Colonel Stewart who was governor of Edinburgh Castle and took part in the Jacobite rising of 1715.
Roberts had a twin brother, William, and they were educated together at Midleton School, Cork. A portrait is reported of Roberts and his twin brother at the age of sixteen. He entered TCD in 1833. He was awarded a classical scholarship in 1836, but studied mostly under the notable mathematician and natural philosopher James MacCullagh. On graduating BA in 1838, he was elected a fellow of Trinity, and in 1862 became Erasmus Smith's Professor of Mathematics, a position he held until 1879, when he was elected as Senior Fellow. In 1848 he had been appointed the first Professor of Mathematics at Queen's College, Galway, but he resigned from the position before the college opened to students in 1849.
Research
Among Roberts's earlier lectures were a series on the Theory of Invariants and Covariants, on which he published papers. Next he took an interest in hyperelliptic integrals, a subject developed by Jacobi, Riemann, and Weierstrass. In 1871 he published a "Tract on the Addition of Elliptic and Hyperelliptic Integrals", constructing a trigonometry of hyperelliptic functions on the analogy of that of elliptic functions.
Roberts discovered many properties of geodesic lines and lines of curvature on the ellipsoid, especially in relation to umbilics, and from 1845 published papers in the Journal de Mathématiques, the Proceedings of the Royal Irish Academy, Cambridge and Dublin Mathematical Journal, Nouvelles Annales de Mathématiques. In 1850 he wrote in the Journal de Mathématiques of the lines of curvature and asymptotic lines on a surface, at any point of which the sum of the principal curvatures is zero. The International Exhibition of 1851 at Hyde Park displayed a small model ellipsoid, on which the lines of curvature had been traced according to a method Roberts invented. Roberts published several papers on the properties and functions of the roots of algebraic equations, and on covariants and invariants. From 1868 to 1873 he published work in Annali di Matematica, including in 1869 and 1871 two papers on Abelian function.
Personal life
In 1851, Roberts married Kate Atkin, a daughter of John Drew Atkin, of Merrion Square, Dublin, and they had seven children, three sons and four daughters.
In the 1870s, his health began to fail, and he died in Dublin in October 1882.

https://en.wikipedia.org/wiki/Binary%20regression | In statistics, specifically regression analysis, a binary regression estimates a relationship between one or more explanatory variables and a single output binary variable. Generally the probability of the two alternatives is modeled, instead of simply outputting a single value, as in linear regression.
Binary regression is usually analyzed as a special case of binomial regression, with a single outcome (), and one of the two alternatives considered as "success" and coded as 1: the value is the count of successes in 1 trial, either 0 or 1. The most common binary regression models are the logit model (logistic regression) and the probit model (probit regression).
Applications
Binary regression is principally applied either for prediction (binary classification), or for estimating the association between the explanatory variables and the output. In economics, binary regressions are used to model binary choice.
Interpretations
Binary regression models can be interpreted as latent variable models, together with a measurement model; or as probabilistic models, directly modeling the probability.
Latent variable model
The latent variable interpretation has traditionally been used in bioassay, yielding the probit model, where normal variance and a cutoff are assumed. The latent variable interpretation is also used in item response theory (IRT).
Formally, the latent variable interpretation posits that the outcome y is related to a vector of explanatory variables x by
where and , is a vector of parameters and G is a probability distribution.
This model can be applied in many economic contexts. For instance, the outcome can be the decision of a manager whether invest to a program, is the expected net discounted cash flow and x is a vector of variables which can affect the cash flow of this program. Then the manager will invest only when she expects the net discounted cash flow to be positive.
Often, the error term is assumed to follow a normal distribution conditional on the explanatory variables x. This generates the standard probit model.
Probabilistic model
The simplest direct probabilistic model is the logit model, which models the log-odds as a linear function of the explanatory variable or variables. The logit model is "simplest" in the sense of generalized linear models (GLIM): the log-odds are the natural parameter for the exponential family of the Bernoulli distribution, and thus it is the simplest to use for computations.
Another direct probabilistic model is the linear probability model, which models the probability itself as a linear function of the explanatory variables. A drawback of the linear probability model is that, for some values of the explanatory variables, the model will predict probabilities less than zero or greater than one.

https://en.wikipedia.org/wiki/Jeanette%20MacDonald%20discography | American actress/singer Jeanette MacDonald (1903 – 1965) recorded over 50 songs during her film career for RCA Victor and its foreign counterparts. Due to the limited statistics released to the public, it is not certain how many songs and singles she has released or their exact popularity in music charts, although she has officially recorded eight studio albums (five LPs) and released seven compilation albums. Despite soundtracks for musical films not becoming a concept until the 1940s, many of her singles were re-recordings of songs she had performed in the movies (a common practice other musical actors did at the time); her first "album" was the single "Dream Lover"/"March of the Grenadiers" (1930) on 78 rpm discs for The Love Parade. She also recorded a cover album of songs featured in Sigmund Romberg's Up in Central Park in 1945 with Robert Merrill, as well as non-English records during her 1931 European tour.
MacDonald performed in musicals alongside Maurice Chevalier, Allan Jones, and Nelson Eddy, although her films with Eddy are the most well-known today. The single "Ah! Sweet Mystery of Life"/"Indian Love Call" from Rose Marie (1936) received a gold record from RCA Red Seal. Her other popular (and/or well-remembered) singles were "Beyond the Blue Horizon", "San Francisco", and "Ave Maria". "Beyond the Blue Horizon" peaked at #9 in the charts and became MacDonald's signature song; she performed it professionally three times in her career.
MacDonald's first studio album was MacDonald in Song (1939), followed by Religious Songs (1945) and Operetta Favorites (1946). Her first LP was Romantic Moments (1950), followed by Favorites, Favorites in Hi-Fi (1959), Smilin' Through (1960) and Jeanette MacDonald Sings Songs of Faith and Inspiration (1963). Seven official compilation albums were released, such as Jeanette MacDonald 1929–1939 and A Tribute to Jeanette MacDonald volumes 1 and 2, but due to the varying copyrights on audio worldwide, unofficial albums in MacDonald's name have been released on CDs in European countries under public domain.

https://en.wikipedia.org/wiki/Mavis%20Hinds | Mavis Kathleen Hinds (1929–2009) was an English meteorologist who, together with Fred Bushby, pioneered the use of computers to carry out meteorological calculations in the UK. She studied Mathematics at University College London (UCL) and on graduating joined the UK Meteorological (Met) Office in 1951, attending their Initial Forecasting Course that year. She went on to work with Bushby in using the Lyons Electronic Office (LEO), an early computer developed by J. Lyons & Co of Cadby Hall, London, becoming an expert in writing, running and correcting computer programs for weather forecasting. She was seen at that time as one of the first prominent female meteorologists and also the first to play a leading role in the development of Numerical Weather Prediction, not only in the UK but also worldwide.
Early life and education
Hinds passed her Higher School Certificate in pure mathematics, applied mathematics and physics. This was an ideal combination of subjects for the study of meteorology in which she was already developing an interest. On the strength of her examination results, Mavis was awarded a scholarship and a place to read Mathematics at University College London (UCL).
Research and career
From 1951 Hinds worked at the UK Met Office as part of their Forecast Research Division, which had been set up in 1949 in Dunstable, England. Hinds, as part of the Division, was instrumental in the development of Numerical Weather Prediction (NWP). The earliest days of NWP in the late 1940s relied on hand calculation but as electronic computing machines began to be developed in the US (ENIAC) and the UK (EDSAC and LEO I), NWP grew in reliability and prevalence. In 1954 at a meeting of the Royal Meteorological Society, Bushby and Hinds presented the first computer-based baroclinic forecast in Europe. Since 1951, they had been making use of the computing power of the first Lyons Electronic Office (LEO), the world's first business computer, developed by J. Lyons & Co caterers of Cadby Hall, London.
Because in the early 1950s the UK Met Office had no in-house computing facilities, calculating power had to be obtained from part-time use of LEO I and also the Ferranti Mark 1 Star at the University of Manchester. Use of these very early computers involved working unsociable hours when the machines were not being used by others. Throughout the 1950s and 1960s Hinds worked with Fred Bushby and others on a series of published papers that detailed the developments made.
In 1981, Hind reflected on the impact of computing on weather prediction that started for her with work done using the LEO I and in 1994 contributed a chapter about the history of UK Met Office computerisation to Peter Bird's book on the development of the LEO computers
Hinds later worked in management roles before her retirement in 1989.

History
Editori Riuniti was founded in 1953 by the merger of the Italian Communist Party's two existing publishing houses, 's Edizioni Rinascita and 's Edizioni di Cultura Sociale. Bonchio became head of the new publishing house and initiated, in its first decade, a period of expansion. Editori Riuniti began publishing its flagship magazines, which were initially edited by Bonchio and Gerratana until Bruno Munari contributed to their graphic design. The publishing house also began important partnerships with European intellectuals like Maurice Dobb, Louis Althusser, Eric Hobsbawm, and Roberto Longhi. In the 1970s, Editori Riuniti published the Opere complete di Marx e Engels and the 11-volume encyclopedia Ulisse, under the direction of Lucio Lombardo-Radice.
The publishing house entered a period of economic crisis in the 1980s that lasted until the formation of the Editori Riuniti University Press in 2007, in 2014 the company was reunified under the name of Editori Riuniti.
Publishing
Editori Riuniti published the complete works of both Karl Marx and Friedrich Engels in Italian.

https://en.wikipedia.org/wiki/IM%2067118 | IM 67118, also known as Db2-146, is an Old Babylonian clay tablet in the collection of the National Museum of Iraq that contains the solution to a problem in plane geometry concerning a rectangle with given area and diagonal. In the last part of the text, the solution is proved correct using the Pythagorean theorem. The steps of the solution are believed to represent cut-and-paste geometry operations involving a diagram from which, it has been suggested, ancient Mesopotamians might, at an earlier time, have derived the Pythagorean theorem.
Description
The tablet was excavated in 1962 at Tell edh-Dhiba'i, an Old Babylonian settlement near modern Baghdad that was once part of the kingdom of Eshnunna, and was published by Taha Baqir in the same year. It dates to approximately 1770 BCE (according to the middle chronology), during the reign of Ibal-pi-el II, who ruled Eshnunna at the same time that Hammurabi ruled Babylon. The tablet measures 11.5×6.8×3.3 cm (4½" x 2¾" x 1¼"). Its language is Akkadian, written in cuneiform script. There are 19 lines of text on the tablet's obverse and six on its reverse. The reverse also contains a diagram consisting of the rectangle of the problem and one of its diagonals. Along that diagonal is written its length in sexagesimal notation; the area of the rectangle is written in the triangular region below the diagonal.
Problem and its solution
In modern mathematical language, the problem posed on the tablet is the following: a rectangle has area A = 0.75 and diagonal c = 1.25. What are the lengths a and b of the sides of the rectangle?
The solution can be understood as proceeding in two stages: in stage 1, the quantity is computed to be 0.25. In stage 2, the well-attested Old Babylonian method of completing the square is used to solve what is effectively the system of equations b − a = 0.25, ab = 0.75. Geometrically this is the problem of computing the lengths of the sides of a rectangle whose area A and side-length difference b−a are known, which was a recurring problem in Old Babylonian mathematics. In this case it is found that b = 1 and a = 0.75. The solution method suggests that whoever devised the solution was using the property c2 − 2A = c2 − 2ab = (b − a)2. It must be emphasized, however, that the modern notation for equations and the practice of representing parameters and unknowns by letters were unheard of in ancient times. It is now widely accepted as a result of Jens Høyrup's extensive analysis of the vocabulary of Old Babylonian mathematics, that underlying the procedures in texts such as IM 67118 was a set of standard cut-and-paste geometric operations, not a symbolic algebra.
From the vocabulary of the solution Høyrup concludes that c2, the square of the diagonal, is to be understood as a geometric square, from which an area equal to 2A is to be "cut off", that is, removed, leaving a square with side b − a. Høyrup suggests that the square on the diagonal was possibly formed by making four |
https://en.wikipedia.org/wiki/Resonance%20escape%20probability | In nuclear physics, resonance escape probability is the probability that a neutron will slow down from fission energy to thermal energies without being captured by a nuclear resonance. A resonance absorption of a neutron in a nucleus does not produce nuclear fission. The probability of resonance absorption is called the resonance factor , and the sum of the two factors is .
Generally, the higher the neutron energy, the lower the probability of absorption, but for some energies, called resonance energies, the resonance factor is very high. These energies depend on the properties of heavy nuclei. Resonance escape probability is highly determined by the heterogeneous geometry of a reactor, because fast neutrons resulting from fission can leave the fuel and slow to thermal energies in a moderator, skipping over resonance energies before reentering the fuel.
Resonance escape probability appears in the four factor formula and the six factor formula. To compute it, neutron transport theory is used.
Resonant neutron absorption
The nucleus can capture a neutron only if the kinetic energy of the neutron is close to the energy of one of the energy levels of the new nucleus formed as a result of capture. The capture cross section of such a neutron by the nucleus increases sharply. The energy at which the neutron-nucleus interaction cross section reaches a maximum is called the resonance energy. The resonance energy range is divided into two parts, the region of resolved and unresolved resonances. The first region occupies the energy interval from 1 eV to Egr. In this region, the energy resolution of the instruments is sufficient enough to distinguish any resonance peak. Starting from the energy Egr, the distance between resonance peaks becomes smaller than the energy resolution. Subsequently, the resonance peaks are not separated. For heavy elements, the boundary energy Egr≈1 keV.
In thermal neutron reactors, the main resonant neutron absorber is Uranium-238. In the table for 238U, several resonance neutron energies Er, the maximum absorption cross sections σa, r in the peak, and the width G of these resonances are given.
Effective resonance integral
Let us assume that the resonant neutrons move in an infinite system consisting of a moderator and 238U. When colliding with the moderator nuclei, the neutrons are scattered, and with the 238U nuclei, they are absorbed. The former collisions favor the retention and removal of resonant neutrons from the danger zone, while the latter lead to their loss.
The probability of avoiding resonance capture (coefficient φ) is related to the density of nuclei NS and the moderating power of the medium ξΣS by the relationship below,
The JeFF value is called the effective resonance integral. It characterizes the absorption of neutrons by a single nucleus in the resonance region and is measured in barnes. The use of the effective resonance integral simplifies quantitative calculations of resonance absorption without |

https://en.wikipedia.org/wiki/%E2%84%93-adic%20sheaf | In algebraic geometry, an ℓ-adic sheaf on a Noetherian scheme X is an inverse system consisting of -modules in the étale topology and inducing .
Bhatt–Scholze's pro-étale topology gives an alternative approach.
Motivation
The development of étale cohomology as a whole was fueled by the desire to produce a 'topological' theory of cohomology for algebraic varieties, i.e. a Weil cohomology theory that works in any characteristic. An essential feature of such a theory is that it admits coefficients in a field of characteristic 0. However, constant étale sheaves with no torsion have no interesting cohomology. For example, if is a smooth variety over a field , then for all positive . On the other hand, the constant sheaves do produce the 'correct' cohomology, as long as is invertible in the ground field . So one takes a prime for which this is true and defines -adic cohomology as .
This definition, however, is not completely satisfactory: As in the classical case of topological spaces, one might want to consider cohomology with coefficients in a local system of -vector spaces, and there should be a category equivalence between such local systems and continuous -representations of the étale fundamental group.
Another problem with the definition above is that it behaves well only when is a separably closed. In this case, all the groups occurring in the inverse limit are finitely generated and taking the limit is exact. But if is for example a number field, the cohomology groups will often be infinite and the limit not exact, which causes issues with functoriality. For instance, there is in general no Hochschild-Serre spectral sequence relating to the Galois cohomology of .
These considerations lead one to consider the category of inverse systems of sheaves as described above. One has then the desired equivalence of categories with representations of the fundamental group (for -local systems, and when is normal for -systems as well), and the issue in the last paragraph is resolved by so-called continuous étale cohomology, where one takes the derived functor of the composite functor of taking the limit over global sections of the system.
Constructible and lisse ℓ-adic sheaves
An ℓ-adic sheaf is said to be
constructible if each is constructible.
lisse if each is constructible and locally constant.
Some authors (e.g., those of SGA 4) assume an ℓ-adic sheaf to be constructible.
Given a connected scheme X with a geometric point x, SGA 1 defines the étale fundamental group of X at x to be the group classifying finite Galois coverings of X. Then the category of lisse ℓ-adic sheaves on X is equivalent to the category of continuous representations of on finite free -modules. This is an analog of the correspondence between local systems and continuous representations of the fundament group in algebraic topology (because of this, a lisse ℓ-adic sheaf is sometimes also called a local system).

https://en.wikipedia.org/wiki/Random%20cluster%20model | In statistical mechanics, probability theory, graph theory, etc. the random cluster model is a random graph that generalizes and unifies the Ising model, Potts model, and percolation model. It is used to study random combinatorial structures, electrical networks, etc. It is also referred to as the RC model or sometimes the FK representation after its founders Cees Fortuin and Piet Kasteleyn.
Definition
Let be a graph, and be a bond configuration on the graph that maps each edge to a value of either 0 or 1. We say that a bond is closed on edge if , and open if . If we let be the set of open bonds, then an open cluster is any connected component in union the set of vertices. Note that an open cluster can be a single vertex (if that vertex is not incident to any open bonds).
Suppose an edge is open independently with probability and closed otherwise, then this is just the standard Bernoulli percolation process. The probability measure of a configuration is given as
The RC model is a generalization of percolation, where each cluster is weighted by a factor of . Given a configuration , we let be the number of open clusters, or alternatively the number of connected components formed by the open bonds. Then for any , the probability measure of a configuration is given as
Z is the partition function, or the sum over the unnormalized weights of all configurations,
The partition function of the RC model is a specialization of the Tutte polynomial, which itself is a specialization of the multivariate Tutte polynomial.
Special values of q
The parameter of the random cluster model can take arbitrary complex values. This includes the following special cases:
: linear resistance networks.
: negatively-correlated percolation.
: Bernoulli percolation, with .
: the Ising model.
: -state Potts model.
Edwards-Sokal representation
The Edwards-Sokal (ES) representation of the Potts model is named after Robert G. Edwards and Alan D. Sokal. It provides a unified representation of the Potts and random cluster models in terms of a joint distribution of spin and bond configurations.
Let be a graph, with the number of vertices being and the number of edges being . We denote a spin configuration as and a bond configuration as . The joint measure of is given as
where is the uniform measure, is the product measure with density , and is an appropriate normalizing constant. Importantly, the indicator function of the set
enforces the constraint that a bond can only be open on an edge if the adjacent spins are of the same state, also known as the SW rule.
The statistics of the Potts spins can be recovered from the cluster statistics (and vice versa), thanks to the following features of the ES representation:
The marginal measure of the spins is the Boltzmann measure of the q-state Potts model at inverse temperature .
The marginal measure of the bonds is the random-cluster measure with parameters q and p.

https://en.wikipedia.org/wiki/National%20Programme%20on%20Technology%20Enhanced%20Learning | The National Programme on Technology Enhanced Learning (NPTEL) is an Indian e-learning platform for university-level science, technology, engineering, and mathematics (STEM) subjects. It is jointly developed by Indian Institutes of Technology (IITs) and Indian Institute of Science. The initiative is funded by the central Ministry of Education. The project's central idea is to put recorded lectures taught by its member institutes online for open access. It operates an educational YouTube channel covering engineering, basic sciences, and some humanities and social science subjects.
History
NPTEL was launched in 2003 by seven IITs: Bombay, Delhi, Kanpur, Kharagpur, Madras, Guwahati and Roorkee, in conjunction with the Indian Institute of Science (IISC). In March 2014, NPTEL began offering courses along with in-centre and proctored certification examinations. Course credits can also be transferred to other higher education institutions student or the Academic Bank of Credits under the UGC guidelines. It is the largest e-repository in the world of courses in engineering, basic sciences and selected humanities and management subjects. The initiative runs through MOOCs model so that students outside IIT system can also participate in learning quality content and get certified provided they meet the passing criteria in the exams conducted at the end of the NPTEL semesters. All courses are free to enrol and learn from. The certification exam is optional and comes at a fee of Rs 1000 per course exam.
The headquarters of NPTEL is located inside IIT Madras.

https://en.wikipedia.org/wiki/Surface%20growth | In mathematics and physics, surface growth refers to models used in the dynamical study of the growth of a surface, usually by means of a stochastic differential equation of a field.
Examples
Popular growth models include:
KPZ equation
Dimer model
Eden growth model
SOS model
Self-avoiding walk
Abelian sandpile model
Kuramoto–Sivashinsky equation (or the flame equation, for studying the surface of a flame front)
They are studied for their fractal properties, scaling behavior, critical exponents, universality classes, and relations to chaos theory, dynamical system, non-equilibrium / disordered / complex systems.
Popular tools include statistical mechanics, renormalization group, rough path theory, etc.
Kinetic Monte Carlo surface growth model
Kinetic Monte Carlo (KMC) is a form of computer simulation in which atoms and molecules are allowed to interact at given rate that could be controlled based on known physics. This simulation method is typically used in the micro-electrical industry to study crystal surface growth, and it can provide accurate models surface morphology in different growth conditions on a time scales typically ranging from micro-seconds to hours. Experimental methods such as scanning electron microscopy (SEM), X-ray diffraction, and transmission electron microscopy (TEM), and other computer simulation methods such as molecular dynamics (MD), and Monte Carlo simulation (MC) are widely used.
How KMC surface growth works
1. Absorption process
First, the model tries to predict where an atom would land on a surface and its rate at particular environmental conditions, such as temperature and vapor pressure. In order to land on a surface, atoms have to overcome the so-called activation energy barrier. The frequency of passing through the activation barrier can by calculated by the Arrhenius equation:
where A is thermal frequency of molecular vibration, k is Boltzmann constant.
2. Desorption process
When atoms land on a surface, there are two possibilities. First, they would diffuse on the surface and find other atoms to make a cluster, which will be discussed below. Second, they could come off of the surface or so-called desorption process. The desorption is described exactly as in the absorption process, with the exception of a different activation energy barrier.
For example, if all positions on the surface of the crystal are energy equivalent, the rate of growth can be calculated from Turnbull formula:
where, ∆G = Ein – Eout, Aout, Ao out are frequencies to go in or out of crystal for any given molecule on the surface, h - height of the molecule in the growth direction, Co concentration of the molecules in direct distance from the surface.
3. Diffusion process on surface
Diffusion process can also be calculated with Arrhenius equation:
where, D is diffusion coefficient, Ed is diffusion activation energy.
All three processes strongly depend on surface morphology at a certain time. For example, atoms tend to len |

https://en.wikipedia.org/wiki/Simon%20Bruce-Lockhart | Simon C. Bruce-Lockhart (born 1949), is a Scottish-Canadian schoolmaster who taught at several schools in Canada between 1972 and 2015.
He was first an English and Mathematics teacher, and then also a housemaster, at his old school, Ridley College, and later a housemaster at Lakefield College School, then was successively Head of School at Albert College, Belleville, Shawnigan Lake School, Mulgrave School, and Glenlyon Norfolk School, the last three of which are in British Columbia.
Early life
Bruce-Lockhart is one of the sons of Patrick Bruce Lockhart (1918–2009), an obstetrician, by his marriage in 1942 to Mary Campbell Seddall. His parents emigrated from Britain to Canada in 1953, and after his mother's death in 1960 his father remarried and had more children, two more sons and a daughter.
He is the brother of Michael Bruce-Lockhart (born 1947), now retired as Professor of Computer Engineering at Memorial University of Newfoundland, and they also have a younger full sister, Ferelyth.
The Bruce Lockhart family has a long tradition of teaching. Bruce-Lockhart's grandfather, John Bruce Lockhart, was headmaster of Sedbergh School, in the north of England, and two of his uncles, Rab and Logie Bruce Lockhart, were headmasters who had played rugby union for Scotland. His great-grandfather, Robert Bruce Lockhart (1858–1950), was a Scottish headmaster born at Montreal, in Canada, and he lived long enough for them to meet.
Bruce-Lockhart was educated at Ridley College, Ontario, from 1962 to 1967, where he was a school prefect in his final year,
and Yale, where he graduated BA.
Career
Following in the family tradition, after Yale, Bruce-Lockhart trained for a teaching career. In 1972 he returned to Ridley College, his old school, as a master, to teach English and Mathematics, but took time out from 1975 to 1976 to spend a year at Dalhousie University studying law. He then returned to Ridley as housemaster of Gooderham House, before moving on in 1979 to Lakefield College School, in Selwyn, Ontario, again as a housemaster, and became also the school's director for admissions. In 1986 he was appointed as head of school at Albert College, Belleville, where he remained until 1990. After that, he was head of school at Shawnigan Lake School, on Vancouver Island, from 1990 to 2000, Mulgrave School, West Vancouver, in 2003–2004, and Glenlyon Norfolk School, also in British Columbia, from 2004 to 2015.
In 1990, shortly after his arrival at Shawnigan Lake School, Bruce-Lockhart persuaded Jason Dorland to come to the school as a rowing coach, and Dorland has described him as "a big man", a rugby, football, and hockey player with "gentleness and kindness about him".

https://en.wikipedia.org/wiki/Legion%20of%20Super-Heroes%20Volume%20I | Legion of Super-Heroes Volume I is a 1986 role-playing game supplement for DC Heroes published by Mayfair Games.
Plot summary
Legion of Super-Heroes Volume I features game statistics and background information for all the major characters of the Legion of Super-Heroes.
Reception
Pete Tamlyn reviewed Legion of Super-Heroes for White Dwarf #88, and stated that "it's another monster manual: page upon page of characters out of DC Comics reduced to game statistics and a brief biography. It's fascinating for comics experts, a must for fans of the characters featured, and a big yawn for the reviewer".
Michael R. Jarrell reviewed Legion of Super-Heroes Volume I in Space Gamer/Fantasy Gamer No. 78. Jarrell commented that "I have to urge you to run out to your local game store and take a look at this fine Mayfair supplement. if you like it then buy it. Bugs and all. I don't think you'll regret it".

Luna Parc is the semi-private museum, atelier, and private home of 21st century American multimedia artist Richard "Ricky" Boscarino located in Sandyston Township, New Jersey, United States. Twice a year, the museum and atelier are opened to the public for a three-weekday Open House.
Description
Luna Parc comprises multiple buildings and outdoor art pieces set in an 8.5-acre densely-wooded landscape. These structures are built from metal, clay, glass, wood, rock, ceramic, cement, and ferro-cement. They are designed in a whimsical architectural style, featuring vivid colors, curving surfaces, detailed mosaic tiling, and incorporating unusual objects such as bowling balls and license plates.
The fantastical outdoor appearance of Luna Parc resembles Gaudí's Park Güell in Barcelona, Spain, and the Hundertwasser House in Vienna, Austria, because Boscarino drew inspiration from both these European sites.
The main building is a 5,000 square foot residential house. The interior of this house is a cabinet of curiosities exhibiting thousands of artifacts ranging from the exotic (e.g., Tibetan yak leather pouch) to the absurd (human fallopian tubes floating in a glass vessel). Also on display inside are Boscarino's individual works of art such as his oil paintings and articulated metallic insect jewelry.
Related organization
Boscarino is also an officer in The Luna Parc Atelier Foundation Inc. The Foundation is a not-for-profit entity registered under US IRC as a 501(c)(3) organization that serves as an art colony and is chartered to teach and provide hands-on training to aspiring artists and apprentice workers. One mission of the Foundation is to ensure the continued existence of Luna Parc as a creative museum. Much of the Foundation's training, events, and fundraising takes place on the grounds of Luna Parc.
Critical reception
Mark Sceurman, co-creator and publisher of History Channel's reality television series Weird U.S., described Luna Parc in 2014 as "Of all the places we've seen, I think this is the strangest".

}The Congo Children Trust is a registered charity in Wales and England. They support street children in the D.R.Congo through projects and partner organisations. The vision of the Congo Children Trust is to "improve the quality of life for children living on the streets in the Democratic Republic of Congo".
History
The Congo Children Trust was formed in 2007 by Ian Harvey. Ian set up the trust after working in Kinshasa, which is the capital of D.R.Congo, during the first democratic elections in 2006. During this time, Ian observed a sharp rise in the numbers of street children since previously working in the D.R.Congo in the 1990s. The increased number of street children in the D.R.Congo had been a result of the wars during 1996-1997 and 1998-2003.
Street children in the D.R.Congo
It is estimated that there are 250,000 children living on the streets in the D.R.Congo. Children find themselves homeless through a number of factors, accusations of witchcraft, poverty, a death of one/both parents due to HIV/AIDS or malaria, extended family being unable to support the child and parental separation. Whilst living on the street the children are exposed to daily violence, sexual, physical and emotional abuse. The street children lack secure access to their basic needs such as food and shelter.
Projects
The Congo Children Trust's main project is Kimbilio, which receives 98% of the funding raised by the trust. The Kimbilio project, set up in 2009, is based in Lubumbashi, D.R.Congo. Kimbilio runs a day centre and four homes for street children in Lubumbashi and seeks to reunite children with their families.
In 2021, Kimbilio opened a primary school for former street children and children whose families are on zero or low income.
Trustees and staff
The Congo Children Trust has no paid members of staff in the UK, all staff are volunteers.
Ian Harvey
Ian Harvey is the founder of the Children Congo Trust and set up the Kimbilio project. Harvey attended the University of London, where he studied Social Anthropology. After being qualified as a Social Worker, Ian worked in child protection. Harvey managed Manchester's social work team, where he supported and assessed unaccompanied asylum seeking young people and children. In 2009 Harvey moved to D.R.Congo and set up project Kimbilio. In 2013 Harvey returned to the UK to oversee the development and running of Kimbilio.
Mark Gant
Mark Gant is the treasurer of the Congo Children Trust. Gant is the Head of Modern Languages at the University of Chester. Gant was involved in the establishment and initial planning of the Kimbilio project.

https://en.wikipedia.org/wiki/Wine/water%20paradox | The wine/water paradox is an apparent paradox in probability theory. It is stated by Michael Deakin as follows:
The core of the paradox is in finding consistent and justifiable simultaneous prior distributions for and .
Calculation
This calculation is the demonstration of the paradoxical conclusion when making use of the principle of indifference.
To recapitulate, We do not know , the wine to water ratio.
When considering the numbers above, it is only known that it lies in an interval between the minimum of one quarter wine over three quarters water on one end (i.e. 25% wine), to the maximum of three quarters wine over one quarter water on the other (i.e. 75% wine). In term of ratios, resp. .
Now, making use of the principle of indifference, we may assume that is uniformly distributed. Then the chance of finding the ratio below any given fixed threshold , with , should linearly depend on the value . So the probability value is the number
As a function of the threshold value , this is the linearly growing function that is resp. at the end points resp. the larger .
Consider the threshold , as in the example of the original formulation above. This is two parts wine vs. one part water, i.e. 66% wine. With this we conclude that
.
Now consider , the inverted ratio of water to wine but the equivalent wine/water mixture threshold. It lies between the inverted bounds.
Again using the principle of indifference, we get
.
This is the function which is resp. at the end points resp. the smaller .
Now taking the corresponding threshold (also half as much water as wine). We conclude that
.
The second probability always exceeds the first by a factor of . For our example the numbers is .
Paradoxical conclusion
Since , we get
,
a contradiction.

https://en.wikipedia.org/wiki/3-4-3-12%20tiling | In geometry of the Euclidean plane, the 3-4-3-12 tiling is one of 20 2-uniform tilings of the Euclidean plane by regular polygons, containing regular triangles, squares, and dodecagons, arranged in two vertex configuration: 3.4.3.12 and 3.12.12.
The 3.12.12 vertex figure alone generates a truncated hexagonal tiling, while the 3.4.3.12 only exists in this 2-uniform tiling. There are 2 3-uniform tilings that contain both of these vertex figures among one more.
It has square symmetry, p4m, [4,4], (*442). It is also called a demiregular tiling by some authors.
Circle Packing
This 2-uniform tiling can be used as a circle packing. Cyan circles are in contact with 3 other circles (1 cyan, 2 pink), corresponding to the V3.122 planigon, and pink circles are in contact with 4 other circles (2 cyan, 2 pink), corresponding to the V3.4.3.12 planigon. It is homeomorphic to the ambo operation on the tiling, with the cyan and pink gap polygons corresponding to the cyan and pink circles (one dimensional duals to the respective planigons). Both images coincide.
Dual tiling
The dual tiling has kite ('ties') and isosceles triangle faces, defined by face configurations: V3.4.3.12 and V3.12.12. The kites meet in sets of 4 around a center vertex, and the triangles are in pairs making planigon rhombi. Every four kites and four isosceles triangles make a square of side length .
This is one of the only dual uniform tilings which only uses planigons (and semiplanigons) containing a 30° angle. Conversely, 3.4.3.12; 3.122 is one of the only uniform tilings in which every vertex is contained on a dodecagon.
Related tilings
It has 2 related 3-uniform tilings that include both 3.4.3.12 and 3.12.12 vertex figures:
This tiling can be seen in a series as a lattice of 4n-gons starting from the square tiling. For 16-gons (n=4), the gaps can be filled with isogonal octagons and isosceles triangles.

https://en.wikipedia.org/wiki/Lumini%C8%9Ba%20Vese | Luminița Aura Vese is a Romanian professor of mathematics at the University of California, Los Angeles, known for her research in image processing, including work on active contour models, level-set methods, image segmentation, and inpainting.
Contributions
The Chan–Vese method of image segmentation using active contours is named after her and Tony F. Chan; Chan and Vese published the method in 2001.
The Vese–Osher and Osher–Solé–Vese models are optimization problems used for noise reduction of images, by decomposing an image into a sum of signal and noise in a way that optimizes a combination of measures of the smoothness of the image and the total amount of noise. They are again named after Vese, and her co-authors Stanley Osher and Andrés Solé on two papers published in 2003.
With Carole Le Guyader, Vese is the author of the book Variational Methods in Image Processing (CRC Press, 2016).
Education and career
Vese earned bachelor's and master's degrees in 1992 at the West University of Timișoara in Romania. She then moved to the University of Nice Sophia Antipolis in France, earning a second master's degree in 1992 and completing her doctorate in 1997. Her dissertation, Problèmes variationnels et EDP pour l’analyse d’image et l’évolution des courbes, was jointly supervised by Gilles Aubert and Michel Rascle. After taking a temporary position at Paris Dauphine University, she joined the University of California, Los Angeles faculty in 2000. She received a Sloan Research Fellowship in 2003.
