https://en.wikipedia.org/wiki/Chessboard%20complex
|
A chessboard complex is a particular kind of abstract simplicial complex, which has various applications in topological graph theory and algebraic topology. Informally, the (m, n)-chessboard complex contains all sets of positions on an m-by-n chessboard, where rooks can be placed without attacking each other. Equivalently, it is the matching complex of the (m, n)-complete bipartite graph, or the independence complex of the m-by-n rook's graph.
Definitions
For any two positive integers m and n, the (m, n)-chessboard complex is the abstract simplicial complex with vertex set that contains all subsets S such that, if and are two distinct elements of S, then both and . The vertex set can be viewed as a two-dimensional grid (a "chessboard"), and the complex contains all subsets S that do not contain two cells in the same row or in the same column. In other words, all subset S such that rooks can be placed on them without taking each other.
The chessboard complex can also be defined succinctly using deleted join. Let Dm be a set of m discrete points. Then the chessboard complex is the n-fold 2-wise deleted join of Dm, denoted by .
Another definition is the set of all matchings in the complete bipartite graph .
Examples
In any (m,n)-chessboard complex, the neighborhood of each vertex has the structure of a (m − 1,n − 1)-chessboard complex. In terms of chess rooks, placing one rook on the board eliminates the remaining squares in the same row and column, leaving a smaller set of rows and columns where additional rooks can be placed. This allows the topological structure of a chessboard to be studied hierarchically, based on its lower-dimensional structures. An example of this occurs with the (4,5)-chessboard complex, and the (3,4)- and (2,3)-chessboard complexes within it:
The (2,3)-chessboard complex is a hexagon, consisting of six vertices (the six squares of the chessboard) connected by six edges (pairs of non-attacking squares).
The (3,4)-chessboard complex is a triangulation of a torus, with 24 triangles (triples of non-attacking squares), 36 edges, and 12 vertices. Six triangles meet at each vertex, in the same hexagonal pattern as the (2,3)-chessboard complex.
The (4,5)-chessboard complex forms a three-dimensional pseudomanifold: in the neighborhood of each vertex, 24 tetrahedra meet, in the pattern of a torus, instead of the spherical pattern that would be required of a manifold. If the vertices are removed from this space, the result can be given a geometric structure as a cusped hyperbolic 3-manifold, topologically equivalent to the link complement of a 20-component link.
Properties
Every facet of contains elements. Therefore, the dimension of is .
The homotopical connectivity of the chessboard complex is at least (so ).
The Betti numbers of chessboard complexes are zero if and only if . The eigenvalues of the combinatorial Laplacians of the chessboard complex are integers.

Västra Älvsala is a locality situated in Värmdö Municipality, Stockholm County, Sweden.
Statistics Sweden demarcated the settlement into a small town between 1995 and 2015 called Fagerdala. In the delimitation of urban areas in 2015, Fagerdala was included in the new urban area of Älvsala. At the clearing in 2020, the settlement was separated from Älvsala and reclassified as a separate locality named Västra Älvsdala.
History
Fagerdala was included in Ulffzala quarter in 1538. The farm was granted in 1638 to Axel Oxenstierna. Hemmanet was burned in 1719 by the Imperial Russian Fleet. During the latter part of the 18th century, the farm was owned by the Psilanderhjelm family in nearby Brevik.
Society
Near the jetty there are some older wooden houses. Some buildings are used as holiday homes, but with an increasing proportion of permanent residences.
Nature
West of Västra Älvsala is the Morträsket wetland with bird and plant life worthy of protection.

Albert George Orr is an Australian entomologist.
Biography
Albert Orr was born in 1953 in Maleny, Queensland. He studied mathematics and entomology at Queensland University and graduated in 1974. He received a PhD from Griffith University in 1988 for work on mating in butterflies. From 1990 worked for 10 years at Universiti Brunei Darussalam, and from 2000, he has been an honorary research fellow at Griffith University.
Publications and awards
In 2003, he published A Guide to the Dragonflies of Borneo, for which he received the Worldwide Dragonfly Association’s 2005 award for outstanding achievements and contributions to the science of odonatology. This book was the first comprehensive guide to the dragonflies of the region.
He and co-author Vincent J. Kalkman were awarded the 2013 Whitley Medal by the Royal Zoological Society of New South Wales for Field Guide to the damselflies of New Guinea. In 2011 he was awarded a Whitley Certificate of Commendation for The Butterflies of Australia. The Butterflies of Australia
received a favourable review i Austral Ecology for being accessible to a less specialist audience, but still providing a large amount of quality scientific insights, and thereby being an excellent complement to Michael Braby's encyclopaedic and definitive Butterflies of Australia. Complete Field Guide to Dragonflies of Australia (second edition), illustrated by Orr, was called an ”invaluable resource” in the Royal Entomological Society’s Review.
He has published four more guides to dragonflies and damselflies of Asia, as the sole author in collaboration with other entomologists. He has been the editor of The Australian Entomologist.

https://en.wikipedia.org/wiki/Mathematics%2C%20science%2C%20technology%20and%20engineering%20of%20the%20Victorian%20era
|
Mathematics, science, technology and engineering of the Victorian era refers to the development of mathematics, science, technology and engineering during the reign of Queen Victoria.
Professionalisation of science
Founded in 1799 with the stated purpose of "diffusing the Knowledge, and facilitating the general Introduction, of Useful Mechanical Inventions and Improvements; and for teaching, by Courses of Philosophical Lectures and Experiments, the application of Science to the common Purposes of Life," the Royal Institution was a proper scientific institution with laboratories, a lecture hall, libraries, and offices. In its first years, the Institution was dedicated to the improvement of agriculture using chemistry, prompted by trade restrictions with Europe. Such practical concerns continued through the next two centuries. However, it soon became apparent that additional funding was required in order for the Institution to continue. Some well-known experts were hired as lecturers and researchers. The most successful of them all was Sir Humphry Davy, whose lectures concerned a myriad of topics and were so popular that the original practical purpose of the Institution faded away. It became increasingly dominated by research in basic science.
The professionalisation of science began in the aftermath of the French Revolution and soon spread to other parts of the Continent, including the German lands. It was slow to reach Britain, however. Master of Trinity College William Whewell coined the term scientist in 1833 to describe the new professional breed of specialists and experts studying what was still commonly known as natural philosophy. In 1840, Whewell wrote, "We need very much a name to describe a cultivator of science in general. I should incline to call him a Scientist." The new term signalled the recognition of the importance of empiricism and inductive reasoning. But this term was slow to catch on. As biologist Thomas Huxley indicated in 1852, the prospect of earning a decent living as a scientist remained remote despite the prestige of the occupation. It was possible for a scientist to "earn praise but not pudding," he wrote. Since its birth, the Royal Society of London had been a club of gentlemanly amateurs, though some of whom were the very best in their fields, people like Charles Darwin and James Prescott Joule. But the Society reformed itself in the 1830s and 1840s. By 1847, it only admitted the new breed of professionals.
The Victorians were impressed by science and progress and felt that they could improve society in the same way as they were improving technology. Britain was the leading world centre for advanced engineering and technology. Its engineering firms were in worldwide demand for designing and constructing railways.
Ease of discovery and rate of progress
A necessary part of understanding scientific progress is the ease of scientific discovery. In many cases, from planetary science to mammalian biology, the ease of

The Department of Statistics Malaysia (DOSM; Malay: Jabatan Perangkaan Malaysia) is a government agency in Malaysia that operates under the Prime Minister's Department. It is responsible for the collection and interpretation of reliable statistics related to the economy, population, society and environment of Malaysia which the government primarily uses to assess, review and implement national public policies.
DOSM data are publicly accessible on the OpenDOSM website.
Responsibilities and activities
MyCensus
The department conducts the Population and housing census of Malaysia (MyCensus) every 10 years. As of the most recent census in 2020, DOSM had implemented 5 censuses since the establishment of Malaysia.
Economic statistics
The department supplies a wide variety of financial information. Through its various divisions, the department is responsible for the production and compilation of national accounts such as quarterly and annual gross domestic product (GDP), national income, consumption, savings, balance of payments (BOP). Other economic statistics such as services statistics, the balance of payments, economic indicators, international trade statistics, industrial production and construction statistics as also frequently compiled by the department.
History
Establishment
The DOSM was established in 1949 under the Statistics Ordinance 1949. It was then known as the Bureau of Statistics and mainly produced statistics related to external trade and estate agriculture
In 1965, the Bureau of Statistics was renamed to its current name as provisioned by the Statistics Act 1965. The department's function and role had also been expanded to include data on the economy and society. Under the act, the Sabah and Sarawak statistics office became a branch of the DOSM. The establishment of state offices in Peninsular Malaysia was done in stages from 1971 to 1982.

Scholz was among the first to combine physics and geological engineering to understand the movement of tectonic plates and earthquakes.
In 1970, Scholz proposed the dilatancy-diffusion model of earthquake prediction that allowed seismologists to study the geophysical effects in rock observed before and during an earthquake. His work also enabled researchers to create regional seismic hazard maps that derives spatial and size distributions of earthquakes from geological observations.
Scholz was elected to the National Academy of Engineering in 2023 "for pioneering experimental and theoretical studies on faulting and earthquake mechanics."
Scholz is also the author of the popular textbook The Mechanics of Earthquakes and Faulting.
Awards
Scholz was awarded the Murchison Medal from the Geological Society of London in 2005 and the Harry Fielding Reid Medal from the Seismological Society of America in 2015. He was a Sloan Research Fellow in 1975–77.

}Nsukka is a region located in Enugu State of Southeastern Nigeria that has drawn particular archaeological interest. This area has yielded several examples of iron, metal, clay, and stone production that have contributed to the country’s development over the years. In the territory referred to as Igboland, in which Nsukka resides, Alumona is recognized as a focal point for metal working, whilst Opi, Obimo, Lejja, Orba, Nrobo, Onyohor, Ekwegbe, and Umundu are related back to iron smelting.
Cultural history
Onyohor, Ekwegbe, and Obimo, are all considered part of the old Nsukka territory, which is also part of the tribal territory known as Igboland. The Onyohor and Ekwegbe smelting sites together form the southern border of the Nsukka plateau, whilst the iron smelting site at Obimo is found on the western side of the region. These areas alone provide verification that the Nsukka zone includes differing cultural traits according to these towns that make up the plateau. Similar to the other areas of Igboland, the locations mentioned each have their own histories and stories of origin. These stories fluctuate from the supposed place of Igbo nativity to migration and intermixing.
The oral history of the Onyohor people claim that the five villages that form the town were founded by the sons of Elunyi Ugwunye, the founder of Onyohor. In accordance with one Igwe Mathew Ukpabi, migration did not occur in this region. For the people of Ekwegbe, assertions have been made based on indigenousness, but also a possible trace of migration from Aku and through Umma before reaching Ekwegbe. Ekwegbe married Nome of Ideke Aruona, thus the name, Ekwegbe Odike Arumona, which contributes to the full name of the region - Nsukka Asadu Ideke Alumona. Obimo on the other hand, has versions of its history that lean towards either the Igala influence or the Eri-Nri influence. The more popular understanding was that Attah of Igala's ascendancy was felt more by the earlier settlers of Obimo. These communities were traditionally religionists and economically, were agriculturalists, making the most use of tools such as axes, hoes, and machetes. These adjacent towns evidently interacted with one another through their similar activities, which included artistic pursuits like weaving, carving, basket making, and blacksmithing.
Iron smelting
Iron working is one of the earliest innovations in the continent of Africa. The history of these processes have been poorly represented due to the Eurocentric view that "Africans remained what the Europeans made them". This evidently is not the case, as areas similar to the Nsukka plateau hold proof of iron smelting, a common form of iron working, that has been realized in the region. Proof of these techn

Nicole Michelle Joseph is an American mathematician and scholar of mathematics education whose research particularly focuses on the experiences of African-American girls and women in mathematics, on the effects of white supremacist reactions to their work in mathematics, and on the "intersectional nature of educational inequity". She is an associate professor of mathematics education, in the Department of Teaching and Learning of the Vanderbilt Peabody College of Education and Human Development.
Education and career
Joseph is African American, and is originally from Seattle. After a fall-out with a racist teacher in her elementary school, she was moved to the only open class, an advanced and self-paced classroom in which she first developed a love for mathematics.
She majored in economics, with a minor in mathematics, at Seattle University, where she earned a bachelor's degree in business administration in 1993. After "a few years in the business world", she began working in the Seattle area as a middle school and elementary school mathematics teacher, and as a mathematics coach, from 1999 to 2011. During this period she also studied at Pacific Oaks College Northwest, a former Seattle satellite campus of Pacific Oaks College, a private Quaker college in California. Through Pacific Oaks, she earned a teaching certification for Washington in 2000, and a master's degree in human development in 2003.
In 2011, Joseph completed a Ph.D. in Curriculum & Instruction at the University of Washington. Her dissertation, Black Students and Mathematics Achievement: A Mixed-Method Analysis of In-School and Out-of-School Factors Shaping Student Success, was supervised by James A. Banks. In the same year, she earned a national certification in adolescent mathematics teaching through the National Board for Professional Teaching Standards.
After completing her doctorate, Joseph joined the University of Denver in 2011 as an assistant professor, focusing on educating future mathematics teachers. She moved to Vanderbilt University in 2016, and was tenured there as an associate professor in 2021.
Books
Joseph is the author or editor of books including:
Interrogating Whiteness and Relinquishing Power: White Faculty's Commitment to Racial Consciousness in STEM Classrooms (edited with C. M. Haynes and F. Cobb, Peter Lang Publishers, 2016)Understanding the Intersections of Race, Gender, and Gifted Education: An Anthology by and About Talented Black Girls and Women in STEM (edited, Information Age Publishing, 2020)Making Black Girls Count in Math: A Black Feminist Vision of Transformative Teaching'' (Harvard Education Press, 2022)

The Women's National Basketball Association (WNBA) was founded in 1996 and began play in 1997. The WNBA has kept a record of its win–loss statistics since its inception. There are currently 12 teams that play in the WNBA, and there are also six defunct WNBA teams accounted for in the league's win–loss records.
Of the WNBA's eight inaugural teams, four remain active: the Las Vegas Aces, Los Angeles Sparks, New York Liberty, and the Phoenix Mercury. All four teams are tied for the most games played in WNBA history, with 894. The Atlanta Dream are the WNBA's newest team and began play in 2008. The Dream have the least games played with 538.
Among active teams, the Sparks hold the highest winning percentage at 522–372 (), whereas the Dallas Wings and Washington Mystics are tied for the lowest winning percentage, both holding a 383–483 () record. When considering defunct franchises, the Houston Comets have the highest winning percentage at 241–149 () and the Portland Fire have the lowest with a 37–59 () record. The Sparks also hold the record for most wins (522), while the Wings and Mystics are tied for most losses (483).
In regards to playoff win–loss records, the Minnesota Lynx have the highest winning percentage, with a 43–27 () record. The Washington Mystics hold the lowest winning percentage among active franchises, with an 18–34 () record. Meanwhile, the Sparks hold the record for most playoff games played (90) and wins (47), sharing the latter record with the Mercury. The Sparks also have the most losses (43) in WNBA playoff history. The defunct Portland Fire are the only WNBA franchise to have never qualified for the playoffs, meaning they rank as the team with the fewest playoff games played, wins, and losses (all at 0). Meanwhile, the Charlotte Sting have the lowest all-time playoff win–loss record, at 6–13 (), when considering both active and defunct franchises.

https://en.wikipedia.org/wiki/Didactic%20Contract
|
In didactics, the didactic contract is a concept introduced by Guy Brousseau, a French mathematics didactician. He defines it as "the set of teacher behaviors expected by the learner, and the set of learner behaviors expected by the teacher".
This didactic contract describes the implicit or explicit rules that frame the sharing of responsibilities between the teacher and the learner in relation to the knowledge mobilized or structured. It is therefore a representation of what both parties expect from each other.
Description
Definition
The didactic contract implies an implicit determination, which is neither written nor clearly stated, of the respective roles of the student and the teacher, in the classroom and in relation to knowledge. About the didactic contract, Brousseau states that it is "a relationship that determines, explicitly for a small part, but above all implicitly, what each partner (teacher and the student) is responsible for managing and what they will take care of in one way or another. This system of reciprocal obligation resembles a contract."
The didactic contract is linked to the pedagogical contract, which is focused on the social dimension of the teacher-student relationship.
Paradox
This concept is also linked to the concept of devolution of the problem since it confronts the teacher with a paradox: what they undertake to make the student produce the behaviors they expect, knowing that they deprive the latter of the conditions necessary for the understanding and learning of the targeted notion. This notion highlights a concept: the teacher carries out the "devolution of a problem" and not the communication of knowledge.
Principal ideas
The three principal ideas about this concept are:
The idea of shared responsibility (the teacher owes things to the student, and the student owes things to the teacher: there is a teacher's job and a student's job).
The consideration of the implicit (everything is implicit, they are unspoken).
The relationship to knowledge (Brousseau states it is a communicative situation: the teacher is the sender, the students are the receivers, and the message is knowledge).
The didactic contract is indispensable and has four main functions:
Create a space for dialogue.
Take into consideration the class's customs.
Manage rules and decisions.
Put in interaction.
Interests
The didactic contract is necessary for the students and the teacher to overcome the paradox of the didactic relationship. The teacher does not have the right to tell the child what they want and yet they must make the child produce the expected response.
The didactic contract is also of some help to the teacher because it allows them to interpret the students' responses and recognize them as a sign of learning.
Beginning of the didactic contract
The didactic contract begins at the start of kindergarten. Laurence Garcion-Vautor highlights the importance of rituals carried out every morning in kindergarten classe

https://en.wikipedia.org/wiki/Cement%20industry%20in%20Bolivia
|
The Cement Industry in Bolivia refers to the production, sale and consumption of cement in the country since according to the latest official data from the National Institute of Statistics of Bolivia, the country had a production of around 3.8 million metric tons of cement during the year 2022. In Bolivia there are five large Bolivian companies that produce cement, which are: SOBOCE, FANCESA, COBOCE, ITACAMBA, and ECEBOL.
History
The first cement factory in Bolivia was the Bolivian Cement Society S.A. (SOBOCE) located in the Department of La Paz which was founded on September 24, 1925, and after three years began producing cement in 1928, being the oldest in the country.
On January 21, 1959, the National Cement Factory (FANCESA) was founded in the city of Sucre, which would also enter the Bolivian market. In 1966, the Bolivian Cement Cooperative (COBOCE) was created with headquarters in the city of Cochabamba that would begin to produce cement from the year 1972.
In 1997 another private Bolivian company called "Itacamba Cementos" was born, which would begin to produce cement from that same year. Some time later, the Bolivian government would also intervene in the production of cement in the country, managing to create the Bolivian Cement Productive Public Company (ECEBOL) with its two cement plants, the first located in the municipality of Caracollo in the Department of Oruro and the second plant located in the city of Potosí in the
Department of Potosi.
Production
During the last 32 years, Bolivian cement production has increased considerably reaching a growth of more than 660%, from producing only 500,000 tons in 1990 to 3,888,000 tons in 2022.

The National Postsecondary Student Aid Study (NPSAS) is a study conducted every four years by the National Center for Education Statistics, a division of the Institute of Education Sciences in the U.S. Department of Education. This study captures data regarding how students pay for postsecondary education, with special attention to how families fund higher education. The NPSAS, which has been conducted periodically since 1987, has a complex design, utilizing sampling and weighting to achieve a sample that represents college students nationwide.
Survey content
The NPSAS collects data from a variety of sources:
Institutional student records are collected for each student enrolled in the study. These include student information such as major, admission test scores, grades, and financial data as well as institutional information such as the cost of tuition and institution type.
Student interviews ask about such things as language spoken in participants' childhood homes, expenses while attending college, employment, race/ethnicity.
Parents are surveyed regarding topics such as marital status, income, age, occupation, and the types of financing used to pay for their child's postsecondary education.
Financial Aid (FAFSA) records are collected from the National Student Loan Data System (NSLDS). This data contains information about financial need (in the form of expected family contributions), loans granted, total debt, and repayment status.
In addition, an element called the non-traditional student risk index is calculated using risk factors for dropping out of college. This index includes factors that have been correlated with low persistence such as working full-time, being a single parent, and being enrolled part-time.
Use of NPSAS data in research
Aggregate NPSAS data is made available to the public via the Department of Education's website. Data containing personally identifiable information is only available to researchers who apply for and obtain a restricted use license from the Department of Education.
NPSAS data is used by researchers to identify trends, for example in student loan repayments and the demographics of postsecondary students. This trend data is used in a variety of ways, for example identifying best practices in decreasing inequalities in higher education and means of increasing student persistence.
Selected examples of NPSAS data research include:
A 2019 Pew Research Center report identified a rise in student poverty, particularly at less selective institutions.
An article published in the 2019 volume of the journal Educational Researcher, which discusses the differences in student borrowing across race and ethnicity.
An Urban Institute report published in 2022 studying the impacts of inflation and financial aid borrowing limits on postsecondary students.
A 2022 article in the journal Harvard Educational Review outlines the impact of the post-9/11 GI bill on the college choices of Veterans.

https://en.wikipedia.org/wiki/Persistence%20barcode
|
In topological data analysis, a persistence barcode, sometimes shortened to barcode, is an algebraic invariant of a persistence module that characterizes the stability of topological features throughout a growing family of spaces. Formally, a persistence barcode consists of a multiset of intervals in the extended real line, where the length of each interval corresponds to the lifetime of a topological feature in a filtration, usually built on a point cloud, a graph, a function, or, more generally, a simplicial complex or a chain complex. Generally, longer intervals in a barcode correspond to more robust features, whereas shorter intervals are more likely to be noise in the data. A persistence barcode is a complete invariant that captures all the topological information in a filtration. In algebraic topology, the persistence barcodes were first introduced by Sergey Barannikov in 1994 as the "canonical forms" invariants consisting of a multiset of line segments with ends on two parallel lines, and later, in geometry processing, by Gunnar Carlsson et al. in 2004.
Definition
Let be a fixed field. Then a persistence module indexed over consists of a family of -vector spaces and linear maps for each such that for all . This construction is not specific to ; indeed, it works identically with any totally-ordered set.
A persistence module is said to be of finite type if it contains a finite number of unique finite-dimensional vector spaces. The latter condition is sometimes referred to as pointwise finite-dimensional.
Let be an interval in . Define a persistence module via , where the linear maps are the identity map inside the interval. The module is sometimes referred to as an interval module.
Then for any -indexed persistence module of finite type, there exists a multiset of intervals such that , where the direct sum of persistence modules is carried out index-wise. The multiset is called the barcode of , and it is unique up to a reordering of the intervals.
This result was extended to the case of pointwise finite-dimensional persistence modules indexed over an arbitrary totally-ordered set by William Crawley-Boevey and Magnus Botnan in 2020, building upon known results from the structure theorem for finitely generated modules over a PID, as well as the work of Cary Webb for the case of the integers.

https://en.wikipedia.org/wiki/Symbols%20of%20grouping
|
In mathematics and related subjects, understanding a mathematical expression depends on an understanding of symbols of grouping, such as parentheses (), brackets [], and braces {}. These same symbols are also used in ways where they are not symbols of grouping. For example, in the expression 3(x+y) the parentheses are symbols of grouping, but in the expression (3, 5) the parentheses may indicate an open interval.
The most common symbols of grouping are the parentheses and the brackets, and the brackets are usually used to avoid too many repeated parentheses. For example, to indicate the product of binomials, parentheses are usually used, thus: . But if one of the binomials itself contains parentheses, as in one or more pairs of parentheses may be replaced by brackets, thus: . Beyond elementary mathematics, brackets are mostly used for other purposes, e.g. to denote a closed interval, or an equivalence class, so they appear rarely for grouping.
The usage of the word "parentheses" varies from country to country. In the United States, the word parentheses (singular "parenthesis") is used for the curved symbol of grouping, but in many other countries the curved symbol of grouping is called a "bracket" and the symbol of grouping with two right angles joined is called a "square bracket".
The symbol of grouping knows as "braces" has two major uses. If two of these symbols are used, one on the left and the mirror image of it on the right, it almost always indicates a set, as in , the set containing three members, , , and . But if it is used only on the left, it groups two or more simultaneous equations.
There are other symbols of grouping. One is the bar above an expression, as in the square root sign in which the bar is a symbol of grouping. For example is the square root of the sum. The bar is also a symbol of grouping in repeated decimal digits. A decimal point followed by one or more digits with a bar over them, for example 0., represents the repeating decimal 0.123123123... .
A superscript is understood to be grouped as long as it continues in the form of a superscript. For example if an x has a superscript of the forma+b, the sum is the exponent. For example: x2+3, it is understood that the 2+3 is grouped, and that the exponent is the sum of 2 and 3.
These rules are understood by all mathematicians.
The associative law
In most mathematics, the operations of addition and multiplication are associative.
The associative law for addition, for example, states that . This means that once the associative law is stated, the parentheses are unnecessary and are usually omitted. More generally, any sum, of any number of terms, can be written without parentheses and any product, of any number of factors, can be written without parentheses.
Hierarchy of operations
The "hierarchy of operations", also called the "order of operations" is a rule that saves needing an excessive number of symbols of grouping. In its simplest form, if a number had a plus

Abdul–Aziz Yakubu (4 April 1958 – August 2022) was a mathematical biologist. Yakubu was a professor at Howard University for over 20 years and served as chair of the mathematics department from 2004 to 2014.
Early life and education
Abdul-Aziz Yakubu was born on 4 April 1958 in Accra, the capital city of Ghana. He attended Accra Academy for high school education. Yakubu became interested in math while studying at the University of Ghana - Legon, where he earned his B.S in mathematics and computer science in 1982. In 1985, Yakubu earned his master's degree in applied mathematics from the University of Toledo in Ohio. Before continuing to Howard University, he attended North Carolina State University and received his doctoral degree in applied mathematics in 1990. For his Ph.D., he wrote his dissertation, "Discrete time competitive systems" under the advisement of John Franke.
Career
Yakubu’s first research experience was at North Carolina State University, and his first faculty position was held at Howard University, a historically black research university (HBCU) in Washington, D.C. While at Howard he spent a year as a long-term visitor by participating in “Mathematics in Biology” at the University of Minnesota. The program at the University of Minnesota allowed him to make connections to further his positive contributions to the world, especially his research on infectious diseases in Africa. Two years after his long-term visit, he took a two-year leave from Howard University in 2002 to visit the Department of Statistics and Computational Biology at Cornell University, where he collaborated with Carlos Castillo-Chavez.
After his Cornell experience, he returned to Howard University to focus on mathematical biology. Yakubu had a successful collaboration in scholarly work on exploited fisheries with scientists at the Northeast Fisheries Science Center of Woods Hole, Massachusetts. He worked on projects that investigated biodiversity and infectious diseases with Avner Friedman of the Mathematical Bioscience Institute students at Ohio State University and his graduate students at Howard University. His research on mathematical biology helped him connect with students and researchers internationally. Yakubu has attended and presented his contributions at several research conferences and workshops in Europe and Asia. The National Science Foundation funded DIMACS-MBI Africa initiative, led by Avner Friedmann, Marty Golubitsky, Fred Roberts as well as the NSF-funded Masamu project of Overton Jenda. It made it possible for him to give several lectures in Cameroon, Ghana, Morocco, South Africa, Uganda, and Zambia. Yakubu left on sabbatical leave to MBI.DIMACS in Piscataway, New Jersey, MBI in Columbus, Ohio, NIMBioS in Knoxville, Tennessee, and similar mathematical biology institutes.
Yakubu published his research in several academic journals like the Bulletin of Mathematical Biology, Journal of Mathematical Biology, Mathematical Biosciences, SIA

In probability theory, integral probability metrics are types of distance functions between probability distributions, defined by how well a class of functions can distinguish the two distributions. Many important statistical distances are integral probability metrics, including the Wasserstein-1 distance and the total variation distance. In addition to theoretical importance, integral probability metrics are widely used in areas of statistics and machine learning.
The name "integral probability metric" was given by German statistician Alfred Müller; the distances had also previously been called "metrics with a -structure."
Definition
Integral probability metrics (IPMs) are distances on the space of distributions over a set , defined by a class of real-valued functions on as
here the notation refers to the expectation of under the distribution . The absolute value in the definition is unnecessary, and often omitted, for the usual case where for every its negation is also in .
The functions being optimized over are sometimes called "critic" functions; if a particular achieves the supremum, it is often termed a "witness function" (it "witnesses" the difference in the distributions). These functions try to have large values for samples from and small (likely negative) values for samples from ; this can be thought of as a weaker version of classifers, and indeed IPMs can be interpreted as the optimal risk of a particular classifier.
The choice of determines the particular distance; more than one can generate the same distance.
For any choice of , satisfies all the definitions of a metric except that we may have we may have for some ; this is variously termed a "pseudometric" or a "semimetric" depending on the community. For instance, using the class which only contains the zero function, is identically zero. is a metric if and only if separates points on the space of probability distributions, i.e. for any there is some such that ; most, but not all, common particular cases satisfy this property.
Examples
All of these examples are metrics except when noted otherwise.
The Wasserstein-1 distance (also called earth mover's distance), via its dual representation, has the set of 1-Lipschitz functions.
The related Dudley metric is generated by the set of bounded 1-Lipschitz functions.
The total variation distance can be generated by , so that is a set of indicator functions for any event, or by the larger class .
The closely related Radon metric is generated by continuous functions bounded in .
The Kolmogorov metric used in the Kolmogorov-Smirnov test has a function class of indicator functions, .
The kernel maximum mean discrepancy (MMD) has the unit ball in a reproducing kernel Hilbert space. This distance is particularly easy to estimate from samples, requiring no optimization; it is a proper metric exactly when the underlying kernel is characteristic.

In mathematics, the Sister Beiter conjecture is a conjecture about the size of coefficients of ternary cyclotomic polynomials (i.e. where the index is the product of three prime numbers). It is named after Marion Beiter, a Catholic nun who first proposed it in 1968.
Background
For the maximal coefficient (in absolute value) of the cyclotomic polynomial is denoted by .
Let be three prime numbers. In this case the cyclotomic polynomial is called ternary. In 1895, A. S. Bang proved that . This implies the existence of such that .
Statement
Sister Beiter conjectured in 1968 that . This was later disproved, but a corrected Sister Beiter conjecture was put forward as .
Status
A preprint from 2023 explains the history in detail and claims to prove this corrected conjecture. Explicitly it claims to prove

https://en.wikipedia.org/wiki/Hurwitz%20space
|
In mathematics, in particular algebraic geometry, Hurwitz spaces are moduli spaces of ramified covers of the projective line, and they are related to the moduli of curves. Their rational points are of interest for the study of the inverse Galois problem, and as such they have been extensively studied by arithmetic geometers. More precisely, Hurwitz spaces classify isomorphism classes of Galois covers with a given automorphism group and a specified number of branch points. The monodromy conjugacy classes at each branch point are also commonly fixed. These spaces have been introduced by Adolf Hurwitz which (with Alfred Clebsch and Jacob Lüroth) showed the connectedness of the Hurwitz spaces in the case of simply branched covers (i.e., the case where is a symmetric group and the monodromy classes are the conjugacy class of transpositions).
Motivation
Let be a finite group. The inverse Galois problem for asks whether there exists a finite Galois extension whose Galois group is isomorphic to . By Hilbert's irreducibility theorem, a positive answer to this question may be deduced from the existence, instead, of a finite Galois extension of Galois group . In other words, one may try to find a connected ramified cover of the projective line over whose automorphism group is . If one requires that this cover be geometrically connected, that is , then this stronger form of the inverse Galois problem is called the regular inverse Galois problem.
A motivation for constructing a moduli space of -covers (i.e., connected covers of whose automorphism group is ) is to transform the regular inverse Galois problem into a problem of Diophantine geometry: if (geometric) points of the moduli spaces correspond to -covers (or extensions of with Galois group ) then it is expected that rational points are related to regular extensions of with Galois group .
This geometric approach, pioneered by John G. Thompson, Michael D. Fried, Gunter Malle and Wolfgang Matzat, has been key to the realization of 25 of the 26 sporadic groups as Galois groups over — the only remaining sporadic group left to realize being the Mathieu group M23.
Definitions
Configuration spaces
Let be a finite group and be a fixed integer. A configuration is an unordered list of distincts points of . Configurations form a topological space: the configuration space of points. This space is the analytification (see GAGA) of an algebraic scheme , which is the open subvariety of obtained by removing the closed subset corresponding to the vanishing of the discriminant.
The fundamental group of the (topological) configuration space is the Artin braid group , generated by elementary braids subject to the braid relations ( and commute if , and ). The configuration space has the homotopy type of an Eilenberg–MacLane space .

Alma Johanna Ruubel (28 September 1899 – 21 January 1990) was an Estonian mathematician and professor engaged in the development of curvilinear representational geometry.
Life and work
Alma Johanna Ruubel was born in Õisu Parish (present-day Viljandi Parish), Viljandi County, and grew up on the Peebu farm in the Ōisu municipality of Viljandimaa. Her father, Juhan Ruubel, was a master builder and joiner and her mother Ann (née Mankin) was a housewife.
In 1909, she entered the three-grade Russian-language Peebu school in Õisu Parish and in 1912, the Viljandi Estonian Educational Society's Estonian-language girls' school from which she graduated in 1916. She continued her studies at the Russian-language Viljandi Girls' High School, which was converted into a seven-grade school during World War I and the German occupation in 1918. In order to continue her studies, Ruubel, together with other girls, formed a group of students of the eighth-grade course, which invited separate teachers. With the end of the German occupation, Viljandi City Girls' High School started working in Viljandi, and Alma's group was included in the eighth grade of the school there. Upon its completion in 1919, Ruubel was allowed to enter a university.
She entered the summer teacher preparation courses organized by the University of Tartu (TRÜ), and in August 1919 she was already selected as a mathematics teacher at the Pärnu Commercial School. From the next school year, she worked as a teacher in her old school in Viljandi. Ruubel also continued her studies in the courses held at the university and finished them in 1921.
University student
She officially entered the University of Tartu in 1926. At first, she earned money by giving tutoring lessons, but in 1929 Professor Gerhard Rägo invited her to become an assistant at the Institute of Mathematics, even though she was only a third-year student. With this, Ruubel became the first female lecturer in mathematics at the University of Tartu. In 1932, she graduated cum laude.
In 1935, she wanted to start research related to numerical and graphical methods. Professor Rägo recommended to her John Couch Adams's method of numerical integration of differential equations and Richard von Mises's recently published error estimation approach to that method. Rägo considered her finished research suitable for submission as a master's thesis. Ruubel received her master's degree in mathematics in 1936. Her thesis, "The JC Adams Method for the Numerical Integration of Ordinary Differential Equations," was recertified in 1946 and she was awarded a Ph.D. in Physics and Mathematics.
Teacher
After graduating from the university, Ruubel continued to work there, first as a senior teacher and later as an associate professor (appointed in 1949). She taught theoretical mechanics, applied mathematics, computational and graphical methods, probability theory, analytical, differential and representational geometry, and higher mathematics.

George A. Willis FAA (born 10 November 1954, Adelaide, South Australia) is an Australian mathematician. Willis received BSc (1976) and BSc (Hons) degrees in mathematics from the University of Adelaide (1977), and a doctorate from the University of Newcastle upon Tyne (1981) under the supervision of Professor B. E. Johnson. He is currently Laureate Professor of Mathematics at the University of Newcastle (Australia). He is best known for his works in group theory, particularly totally disconnected groups.
Career
Willis' career has been largely spent at the University of Newcastle (Australia). He was appointed full Professor as well as ARC Professorial Fellow in 2009, and ARC Laureate Fellow in 2018.
After the conferral of his doctorate degree from the University of Newcastle upon Tyne in 1981, he returned to Australia and took up a position as the Rothman's Postdoctoral Fellow at the University of New South Wales. From 1983 to 1985 he worked at the University of Halifax, Nova Scotia, as the Killam Postdoctoral Fellow, and then returned again to Australia as a Queen Elizabeth II Fellow at the University of Adelaide, before beginning a lectureship at Flinders University of South Australia in 1987. Willis then moved to the Australian National University as a research fellow in 1989, before finally moving to the University of Newcastle (Australia) to take up a lectureship where he is now Emeritus Professor.
During his career he has published widely and has advised 14 PhD students (as of April 2023).
He was Editor-in-Chief of the Journal of the Australian Mathematical Society (Cambridge University Press) from 2012-2019.
Research
Willis' first research paper was published in 1982 based on his research for his doctoral thesis. Willis' early research was centered around functional analysis and harmonic analysis, before shifting into group theory, particularly totally disconnected locally compact (TDLC) groups and the interaction between algebra and topology. Major areas and results include:
Willis' general structural results for totally disconnected locally compact groups paved the way to an understanding of these groups that had remained intractable for 60 years. Out of this body of work came what is now known as "Willis' Theory", a "whole new insight" into the structure and classification of totally disconnected locally compact groups.
In October 2014 an Arbeitsgemeinschaft was held in Oberwolfach dedicated to research on totally disconnected groups.
Willis showed that factorisation in banach and group algebra is possible in cases when the Cohen factorisation theorem does not apply, and decisively closed the argument using negative counterexamples.
Willis and Yehuda Shalom co-authored a paper that answered the conjecture of Margulis and Zimmer for a broad class of groups, and provided a unified framework for considering a number of results and conjectures in the rigidity theory of arithmetic groups. This paper won Willis the 2016 Gavin B

In 1932 he married fellow classicist and Columbia graduate Norma Loewenstein who eventually became professor in the classics department at Brooklyn College. She died in 1938 at age 31. With Morris Raphael Cohen he edited A Sourcebook in Greek Science, a compilation, with commentary, for which Drabkin did many of the translations. This work was not published until much later. From 1941 to 1943 Drabkin was a Carnegie Fellow in Greek and Roman History at the Institute of the History of Medicine at Johns Hopkins University, which, at that time, was directed by Henry E. Sigerist. It was during this period that he produced his translation and commentary on Caelius Aurelianus' On Acute and Chronic Diseases. In 1941 he married the classicist and medical historian Miriam Friedman, who went on to have a long career at City College. They had two children, Susan and William.
During the Second World War Drabkin served as a mathematics instructor in the Army Specialized Training Program. Following the closure of Townsend Harris Hall, he taught mathematics at City College. In the late 1940s, Drabkin noticed an entry in a Swiss manuscript dealer's catalog that he identified as a 13th-century copy of Caelius Aurelianus' Gynaecia, a roughly 5th century Latin translation of a 2nd-century Greek work on gynecology, obstetrics, and diseases of women by Soranus of Ephesus, which, while widely used during the Middle Ages, was long believed lost. Together with Miriam Friedman Drabkin, he edited the work for publication.
In 1953 Drabkin was appointed associate professor in the classics department at City College, and attained the rank of professor in 1957. He served as chairman of the classics department from 1957 until his death. With Stillman Drake, he produced two books on Renaissance science, On Motion and Mechanics, which contained Drabkin's translation of Galileo's De Motu, and Mechanics in 16th Century Italy.
Drabkin received a number of honors for his scholarly work. In 1945–1946 he was a Guggenheim fellow. In 1951 he was the Fielding H. Garrison Lecturer at the American Association for the History of Medicine annual meeting, where he presented the lecture "Soranus and His System of Medici

Nakla el-Anab () is a village in the Beheira Governorate of Egypt. According to the 2006 statistics, the total population of Nakla el-Anab was 22,208 people, including 11,639 men and 10,569 women.
History
Muhammad Ramzi identified it with Aykelah (), a town mentioned by John of Nikiou, which was a birthplace of a Byzantine topoteretes Abaskiron and became a scene of rebellion against the emperor Maurice. After the suppression of the rebellion the town was reportedly set to flames.
He also reports about a conflict that existed between the inhabitants of Nakla and Sais, which revolved around an island between the two towns, which is today called Gazirat Nakla.
"The grapes" () suffix was added to the village's name in the Ottoman period.

Louxin Zhang is a Canadian computational biologist. He is currently a professor in the Department of Mathematics at the National University of Singapore. He is recognized for his contributions to combinatorial semigroup theory in mathematics. In addition, he is recognized for his work on the mathematical understanding of phylogenetic trees and networks, as well as the analysis of spaced seeds for sequence comparison in bioinformatics.
Early life
Louxin Zhang grew up in Luoyang, Henan, China. He graduated from Lanzhou University with an undergraduate degree in mathematics and a master's degree in mathematics. Then he proceeded to Canada to pursue a doctorate in computer science at the University of Waterloo, where he earned his Ph.D. in Computer Science with a thesis entitled "Emulations and Embeddings of Meshes of Trees and Hypercubes of Cliques.
Career
After postdoctoral research in the laboratory of Ming Li, Zhang began his independent research career in 1996 at the Institute of Systems Sciences (currently the Institute for Infocomm Research), where he was awarded a three-year Lee Kuan Yew Postdoctoral Fellowship in 1997. He introduced the string rewriting technique to investigate the word problem and the conjugacy problem in special monoids. He discovered an elegant relationship between gene loss, gene duplication, and incomplete lineage sorting costs. Along with his colleagues, he developed the tree component decomposition method for studying phylogenetic networks. The technique yields a solution to an open problem regarding tree containment, the exact and asymptotic counting of the so-called tree-child networks, and a scalable method for inferring the minimum phylogeny. He also contributed to the theoretical knowledge of spaced seeds for sequence comparison and reconstruction of ancestral genome sequences.

|
In symplectic geometry, a branch of mathematics, Weinstein's neighbourhood theorem refers to a few distinct but related theorems, involving the neighbourhoods of submanifolds in symplectic manifolds and generalising the classical Darboux's theorem. They were proved by Alan Weinstein in 1971.
Darboux-Moser-Weinstein theorem
This statement is a direct generalisation of Darboux's theorem, which is recovered by taking a point as .Let be a smooth manifold of dimension , and and two symplectic forms on . Consider a compact submanifold such that . Then there exist
two open neighbourhoods and of in ;
a diffeomorphism ;
such that and .Its proof employs Moser's trick.
Generalisation: equivariant Darboux theorem
The statement (and the proof) of Darboux-Moser-Weinstein theorem can be generalised in presence of a symplectic action of a Lie group.Let be a smooth manifold of dimension , and and two symplectic forms on . Let also be a compact Lie group acting on and leaving both and invariant. Consider a compact and -invariant submanifold such that . Then there exist
two open -invariant neighbourhoods and of in ;
a -equivariant diffeomorphism ;
such that and .In particular, taking again as a point, one obtains an equivariant version of the classical Darboux theorem.
Weinstein's Lagrangian neighbourhood theorem
Let be a smooth manifold of dimension , and and two symplectic forms on . Consider a compact submanifold of dimension which is a Lagrangian submanifold of both and , i.e. . Then there exist
two open neighbourhoods and of in ;
a diffeomorphism ;
such that and .This statement is proved using the Darboux-Moser-Weinstein theorem, taking a Lagrangian submanifold, together with a version of the Whitney Extension Theorem for smooth manifolds.
Generalisation: Coisotropic Embedding Theorem
Weinstein's result can be generalised by weakening the assumption that is Lagrangian.Let be a smooth manifold of dimension , and and two symplectic forms on . Consider a compact submanifold of dimension which is a coisotropic submanifold of both and , and such that . Then there exist
two open neighbourhoods and of in ;
a diffeomorphism ;
such that and .
Weinstein's tubular neighbourhood theorem
While Darboux's theorem identifies locally a symplectic manifold with , Weinstein's theorem identifies locally a Lagrangian with the zero section of . More preciselyLet be a symplectic manifold and a Lagrangian submanifold. Then there exist
an open neighbourhood of in ;
an open neighbourhood of the zero section in the cotangent bundle ;
a symplectomorphism ;
such that sends to .
Proof
This statement relies on the Weinstein's Lagrangian neighbourhood theorem, as well as on the standard tubular neighbourhood theorem.

|
Below is a list of the head coaches of Croatia national football team, their statistics and achievements in the national team. The Croatian Football Federation considers the date of its foundation to be 1912, when the country itself was still part of Austria-Hungary. In 1919, all sports federations in Croatia came under the jurisdiction of the Kingdom of Serbs, Croats and Slovenes. On 6 August 1939, the HNS regained its independence. On 17 July 1941, FIFA recognized the HNS as the national association of the Independent State of Croatia and considered it a member until the formation of the Socialist Federal Republic of Yugoslavia in 1945. Croatian football players from 1945 to 1990 played for Yugoslavia national team.
The first head coach of the Croatian team was Hugo Kienert, who only formally held this position in 1918–1919, since in those days it was not possible to convene the national team. On the eve and during the World War II, the Croats held a number of friendly meetings, in which it was headed by local experts: Jozo Jakopić, Rudolf Hitrec, Bogdan Cuvaj and Bernard Hügl. During the period of existence of socialist Yugoslavia (from 1945 to 1991), Croatia played only one friendly match in 1956. In this match with the Indonesian national team, it was led by a triumvirate of coaches (Bruno Knežević, Leo Lemešić and Franjo Wölfl). During the period of independence in the early 1990s, the Croatian national team played friendly matches in which Dražan Jerković, Stanko Poklepović and Vlatko Marković were its head coaches.
In 1994, the national team was headed by Miroslav Blažević. It was under his leadership that the Croatian national team achieved its first and impressive success. First, he managed to qualify for the 1996 European Championship, unexpectedly ahead of the Italians, and to leave the group at the championship itself. Under the leadership of Blažević, the Croats created the loudest sensation at the 1998 FIFA World Cup in France, where they win bronze medal.
In the 2000s and the first half of the 2010s, Croats, led by such specialists as Mirko Jozić, Otto Barić, Zlatko Kranjčar, Slaven Bilić, Igor Štimac, Niko Kovač and Ante Čačić, regularly made their way to the final stages of world and continental championships, where occupied either third places in their groups, or stopped at the first stages of the playoffs.
The current head coach of the national team since 7 October 2017 is Zlatko Dalić. He temporarily led the team, which had decisive matches in the selection for the 2018 FIFA World Cup. Having brought his national team to the final part of the tournament, Dalić signed a permanent contract with the HNS. At the World Cup itself, the Croats made a loud sensation, reaching the final match, where they lost against France team with a score of 2–4. Four years later, under the leadership of the same coach, they took the bronze medals of the 2022 FIFA World Cup, in the quarterfinals of which they sensationally defeated Brazil.

In algebra, a Landau-Mignotte bound (sometimes only referred to as Mignotte's bound) is one of a family of inequalities concerning a univariate integer polynomial f(x) and one of its factors h(x). A basic version states that the coefficients of h(x) are bounded independently of h(x) by an exponential expression involving only the degree and coefficients of f(x), i.e. only depending on f(x).
It has applications in computer algebra where these bounds can give a priori estimates on the run time and complexity of algorithms.

Landau's inequality and other basic properties
Landau proved in 1905 a key inequality linking the Mahler measure of a polynomial to its Euclidean norm.
In general norms obey the following inequalities

The Mahler measure is multiplicative, i.e. if then
Mignotte's bound

In set theory, a mathematical discipline, a fundamental sequence is a cofinal sequence of ordinals all below a given limit ordinal. Depending on author, fundamental sequences may be restricted to ω-sequences only or permit fundamental sequences of length . The nth element of the fundamental sequence of is commonly denoted , although it may be denoted or . Additionally, some authors may allow fundamental sequences to be defined on successor ordinals. The term dates back to (at the latest) Veblen's construction of normal functions , while the concept dates back to Hardy's 1904 attempt to construct a set of cardinality .
Definition
Given an ordinal , a fundamental sequence for is a sequence such that and . An additional restriction may be that the sequence of ordinals must be strictly increasing.
Examples
The following is a common assignment of fundamental sequences to all limit ordinals .
for limit ordinals
This is very similar to the system used in the Wainer hierarchy.
Usage
Fundamental sequences arise in some settings of definitions of large countable ordinals, definitions of hierarchies of fast-growing functions, and proof theory. Bachmann defined a hierarchy of functions in 1950, providing a system of names for ordinals up to what is now known as the Bachmann-Howard ordinal, by defining fundamental sequences for namable ordinals below . This system was subsequently simplified by Feferman and Aczel to reduce the reliance on fundamental sequences.
The fast-growing hierarchy, Hardy hierarchy, and slow-growing hierarchy of functions are all defined via a chosen system of fundamental sequences up to a given ordinal. The fast-growing hierarchy is closely related to the Hardy hierarchy, which is used in proof theory along with the slow-growing hierarchy to majorize the provably recursive functions of a given theory.
Additional conditions
A system of fundamental sequences up to is said to have the Bachmann property if for all ordinals in the domain of the system and for all , . If a system of fundamental sequences has the Bachmann property, all the functions in its associated fast-growing hierarchy are monotone, and eventually dominates when .

https://en.wikipedia.org/wiki/Power%20system%20reliability
|
The power system reliability (sometimes grid reliability) is the probability of a normal operation of the electrical grid at a given time. Reliability indices characterize the ability of the electrical system to supply customers with electricity as needed by measuring the frequency, duration, and scale of supply interruptions. Traditionally two interdependent components of the power system reliability are considered:
power system adequacy, a presence in the system of sufficient amounts of generation and transmission capacity;
power system security (also called operational reliability), an ability of the system to withstand real-time contingencies (adverse events, e.g., an unexpected loss of generation capacity).
Ability of the system to limit the scale and duration of an power interruptions is called resiliency. The same term is also used to describe the reaction of the system to the truly catastrophic events.
Economics
Electric grid is an extremely important piece of infrastructure; a single daylong nationwide power outage can shave off 0.5% of the country's GDP. The cost of improvements is also high, so in practice a balance is sought to reach an "adequate level of reliability" at an acceptable cost.
Adequacy
Resource adequacy (RA, also supply adequacy) is the ability of the electric grid to satisfy the end-user power demand at any time (typically this is an issue at the peak demand). For example, a sufficient unused dispatchable generation capacity and demand response resources shall be available to the electrical grid at any time so that equipment failures and fluctuations of power from variable renewable energy sources (e.g., due to wind dying down) can be accommodated.
A typical reliability index for the adequacy is the loss of load expectation (LOLE) of one event in 10 years (one-day-in-ten-years criterion). Due to the possible need for the actual addition of physical capacity, adequacy planning is long term (for example, PJM Interconnection requires capacity purchases to be 4 years in advance of delivery).
Security
Security is the ability of the system to keep the real-time balance of the supply and demand, in particular immediately after a contingency by automatically ramping up generation and shedding the interruptible loads. Security relies on the operating reserve. Historically, the ancillary services (e.g., the inertial response) were provided by the spinning machinery of the synchronous generators, provisioning of these services got more complicated with proliferation of the inverter-based resources (e.g., solar photovoltaics and grid batteries).

|
PAST (PAleontological STatistics) is a free software package for statistical data analysis with a focus on palaeontological data.
Development
PAST's predecessor was PALSTAT, developed by palaeontologists David Harper (University of Copenhagen) and Paul Ryan (National University of Ireland), first for BBC Microcomputer and later for MS-DOS.
The development of PAST started in 1999, the development team consisted of Harper, Ryan as well as Øyvind Hammer (University of Oslo), who is still the maintainer today.
Functions and Operation
PAST includes functions for data management, data visualisation through graphics, univariate and multivariate analysis procedures as well as linear and non-linear modelling. There are also functions for diversity calculation, time series analysis, geostatistical and stratigraphic analysis.
The operation is basically mouse-controlled. In addition, control via syntax scripts is provided, using a Pascal-like script language.
Usage
PAST was used for studies in paleontology, forensics, archaeology or microbiology.
The software was recommended because it is "... designed specifically for paleontologists" and "... incorporates a vast majority of analytical methods suitable for paleontological and current ecological work".

Early life
Langs became interested in baseball as a child growing up in New York City and watching the New York Mets. She gained an affection for the San Francisco Giants from her mother. Conversations about sports and statistics were common in her household.
Langs studied comparative human development at the University of Chicago and wrote about sports for The Chicago Maroon. She interned at the New York Post, Newsweek and The Daily Beast before an internship with Sportsnet New York gave her the opportunity to pitch and write research-based sports stories about the Mets.
Langs' mother is Liise-anne Pirofski, chief of infectious diseases at Albert Einstein College of Medicine and Montefiore Medical Center. Her father, Charles Langs, is a nephrologist at NYU Langone Health.
Career
After graduating in 2015, Langs remained in Chicago, writing research pieces about the Chicago Cubs and Chicago White Sox for NBC Sports Chicago. ESPN soon hired her as a researcher. She supported the hosts of Baseball Tonight with statistics and other historical information.
In 2017, Buster Olney urged Langs to appear on the Baseball Tonight podcast, which led to regular appearances on the podcast and on air. MLB.com hired Langs in 2019, though she continues to work behind the scenes on ESPN broadcasts and appear on Olney's podcast.
In 2021, she served as an on-air analyst as part of Major League Baseball's first all-female broadcast crew, alongside Heidi Watney, Lauren Gardner, Melanie Newman and Alanna Rizzo, calling a YouTube Game of the Week featuring the Baltimore Orioles and Tampa Bay Rays at Tropicana Field. Langs, Watney, Gardner, Newman and Rizzo signed a baseball that was sent to the National Baseball Hall of Fame.
In January 2023, the Baseball Writers' Association of America honored Langs with the Casey Stengel "You Could Look It Up" Award, which is typically presented to someone the group has not otherwise recognized.
Personal life
Langs is in a relationship with Matt Williams, an NBA researcher for ESPN.
Illness
Langs, an avid runner, first noticed an unexplained limp in 2019. In early 2020, she saw an orthopedist, believing that it was an ankle injury. In 2021, Langs was diagnosed with amyotrophic lateral sclerosis, a progressive and terminal illness affecting motor function. She revealed her diagnosis just before the 2022 Major League Baseball postseason. She has continued to work for MLB.com and record podcasts, doing so mostly from home. She has credited her work and the baseball community with helping her to cope with her diagnosis.
Langs ran three half-marathons while experiencing symptoms of what doctors later determined to be ALS.

Girolamo Ghilini (19 May 158912 December 1668) was an Italian writer and scholar of the Seicento. Ghilini was the first who used the term statistics in his unpublished treatise Ristretto della civile, politica, statistica e militare scienza (Alessandria, Bibl. civica, ms. n. 7).
Biography
Girolamo Ghilini was born in Monza, in the Duchy of Milan, in 1589. He studied literature and philosophy at Brera, Milan's Jesuit College. He went afterwards to Parma, where he applied himself to the study of civil and canon law; but was obliged to desist on account of ill health. He returned home, and upon the death of his father he married Giacinta Bagliani. After the death of his wife he embraced the ecclesiastical life and resumed his studies, receiving a degree in canon law and theology. Later he became protonotary apostolic and titular of Saint James Abbey in the village of Cantalupo nel Sannio in southern Italy, but he probably never went there. In 1637 he was made canon of the Collegiate of the Basilica of Sant'Ambrogio, in Milan. Ghilini was a member of the Accademia degli Incogniti of Venice. He died in Alessandria in December 1668. He was buried in the church of San Bernardino.
Works
Ghilini's most important work is his Teatro d'huomini letterati (Theatre of Men of Letters), a biographical dictionary illustrious men. The first part of this work was printed at Milan in 1633. A second enlarged edition was published in Venice, in 1647, in two volumes. Ghilini used sources available to him in Latin, including John Pitts' Relationum historicarum de rebus anglicis, published in paris in 1619. Ghilini's work was praised by Adrien Baillet for its accuracy but harshly criticized by Bernard de la Monnoye for its lack of critical judgement. The Theatro is an important source of knowledge on Italian XVII century writers, and is still quoted to this day. Ghilini was the first to give a literary profile of many English writers unknown in Italy in his day, including Geoffrey Chaucer.

Jarosław Duda (Polish pronunciation: ), also known as Jarek Duda, is a Polish computer scientist and an assistant professor at the Institute of Computer Science and Computational Mathematics of the Jagiellonian University in Kraków. He is known as the inventor of asymmetric numeral systems (ANS), a family of entropy encoding methods widely used in data compression.
Life and career
He was born in Dębica, Subcarpathian Voivodeship, Poland. In 1999, he graduated from King Władysław Jagiełło High School No. 1 in Dębica. In 2004, he obtained an MSc degree in computer science, in 2005 in pure mathematics, in 2006 in physics, all from the Jagiellonian University in Kraków. In 2010, he obtained a Doctor of Philosophy degree in theoretical computer science, then in 2012 doctorate in theoretical physics from the same university. In 2013, he received a one-year postdoctoral fellowship at the NSF Center for Science of Information of the Purdue University at the invitation from Wojciech Szpankowski. In 2015, he was appointed an assistant professor at the Institute of Computer Science and Computational Mathematics of the Jagiellonian University.
Invention of ANS
Between 2006 and 2014 he developed a family of entropy coding methods called asymmetric numeral systems, mainly used in data compression, which has become widely used in electronic devices due to improved performance compared to previous methods. ANS combines the compression ratio of arithmetic coding (which uses a nearly accurate probability distribution), with a processing cost similar to that of Huffman coding. In the tabled ANS (tANS) variant, this is achieved by constructing a finite-state machine to operate on a large alphabet without using multiplication. ANS is used in many products of leading technology companies such as Apple, Facebook, Google, and Linux, for example to encode information in Facebook Zstandard, Apple LZFSE, CRAM or JPEG XL popular data compressors.
Duda's intention has been to keep ANS patent-free and available for public use. In 2018, his lobbying helped convince Google to abandon its ANS-related patent claim in the US and Europe. However, in 2022, Microsoft received a US patent covering modifications to a data-encoding technique called rANS, one of several variants in the Asymmetric Numeral System, introduced by Duda in 2013. In an interview with The Register, Duda raised his concerns about the potential diminished utility of ANS as software developers might try to avoid a potential infringement claim.
Awards
In 2021, he became the recipient of the annual City of Kraków Award for his exceptional achievements in computer science.

https://en.wikipedia.org/wiki/Brunner%20Munzel%20Test
|
In statistics, the Brunner Munzel test (also called the generalized Wilcoxon test) is a nonparametric test of the null hypothesis that, for randomly selected values X and Y from two populations, the probability of X being greater than Y is equal to the probability of Y being greater than X.
It is thus highly similar to the well-known Mann–Whitney U test. The core difference is that the Mann-Whitney U test assumes equal variances and a location shift model, while the Brunner Munzel test does not require these assumptions, making it more robust and applicable to a wider range of conditions. As a result, multiple authors recommend using the Brunner Munzel instead of the Mann-Whitney U test by default.
Assumptions and formal statement of hypotheses
All the observations from both groups are independent of each other,
The responses are at least ordinal (i.e., one can at least say, of any two observations, which is the greater),
Under the null hypothesis H0, is that the probability of an observation from population X exceeding an observation from population Y is the same than the probability of an observation from Y exceeding an observation from X; i.e., or .
The alternative hypothesis H1 is that or
Under these assumptions, the test is consistent and approximately exact test. The crucial difference compared to the Mann–Whitney U test is that the latter is not approximately exact under these assumptions. Both tests are exact when additionally assuming equal distributions under the null hypothesis.
Software implementations
The Brunner Munzel test is available in the following packages

Ernst Lebrecht Henneberg (27 September 1850 – 29 April 1933) was a German professor of mechanics and mathematics.
Life
Ernst Lebrecht Henneberg was born in Wolfenbüttel in 1850 to Heinrich Henneberg and Sophie Rimpau. From 1870 until 1876 he studied mathematics in Zürich, Heidelberg, and Berlin, receiving his doctorate in 1875 from Hermann Schwarz while in Zürich. After living in Zürich from 1876 until 1878, he became an associate professor for descriptive and synthetic geometry and graphic statics at TU Darmstat. Not soon after in 1879, he became a professor of mechanics at the university.
From 1887 to 1890 Henneberg was the dean of the Electrical Engineering school at TU Darmstat. In 1888, Henneburg was elected as a member of the Leopoldina. By 1890, he was one of the founders of the German Association of Mathematicians. From 1890 to 1891 Henneberg had become the dean of the Mathematics and Sciences school, while also acting as the rector from 1891 to 1893.
In 1903 he went on to write an article on graph theory in the Encyclopedia of Mathematical Sciences. The Henneberg's method of bar conversion and the Henneberg minimum surface that he found in his dissertation are named after him.
During both 1902-1905 and 1911-14 he was Dean of the General Department, and on September 30, 1920, he retired from this position. In 1933, Ernst died a professor in the department of Mechanics at TU Darmstat.

|
In mathematics, zero-sum Ramsey theory or zero-sum theory is a branch of combinatorics. It deals with problems of the following kind: given a combinatorial structure whose elements are assigned different weights (usually elements from an Abelian group ), one seeks for conditions that guarantee the existence of certain substructure whose weights of its elements sum up to zero (in ). It combines tools from number theory, algebra, linear algebra, graph theory, discrete analysis, and other branches of mathematics.
The classic result in this area is the 1961 theorem of Paul Erdős, Abraham Ginzburg, and Abraham Ziv: for any elements of , there is a subset of size that sums to zero. (This bound is tight, as a sequence of zeroes and ones cannot have any subset of size summing to zero.) There are known proofs of this result using the Cauchy-Davenport theorem, Fermat's little theorem, or the Chevalley–Warning theorem.
Generalizing this result, one can define for any abelian group G the minimum quantity of elements of G such that there must be a subsequence of elements (where is the order of the group) which adds to zero. It is known that , and that this bound is strict if and only if .

Vaxön is an island in the Stockholm archipelago in Sweden. It is situated in Vaxholm Municipality and Stockholm County. Until 2020, the urban area of Vaxholm, as defined by Statistics Sweden, was entirely contained within the island of Vaxön. However in that year, the adjacent island of Kullö was redefined as part of the urban area.
Vaxön is linked to the Swedish mainland by a series of road bridges, and the car ferry connects Vaxön to the island of Rindö across the Kodjupet strait. A bus service connects the island to Stockholm city, whilst the Waxholmsbolaget and other ferry lines also provide boat services to central Stockholm and many of the other islands of the Stockholm archipelago, using a mixture of classic steamers and modern fast passenger ferries.

In 2001, Honsell was elected Rector of the University of Udine, an office he held until 2008, when he ran as Mayor of Udine.
Political career
Mayor of Udine
In the local elections of 2008, Honsell was elected Mayor of Udine for the centre-left coalition, endorsed by the Democratic Party, The Left – The Rainbow and the Italy of Values. He ran again in the local elections of 2013, endorsed by the Democratic Party, Left Ecology Freedom and the Federation of the Left. He was re-elected mayor.
Regional councillor
On 18 January 2018, Honsell resigned as mayor in order to stand as a candidate in the regional elections in Friuli-Venezia Giulia the following spring with Open - Sinistra FVG, a list supported by Article One, in support of the centre-left presidential candidate Sergio Bolzonello. Honsell is elected to the regional council and later re-elected in the following regional election.
He is a candidate in the 2019 European elections with the Democratic Party list as an independent close to Article One in the North-East Italy constituency; with 28,535 preferences, he comes twelfth as he is not elected.
In the general elections of 2022 he runs for a seat at the Senate in the single-member constituency of Friuli-Venezia Giulia by the centre-left coalition, obtaining 25.98% and losing the challenge against the centre-right candidate Luca Ciriani.

A History of Greek Mathematics is a book by English historian of mathematics Thomas Heath about history of Greek mathematics. It was published in Oxford in 1921, in two volumes titled Volume I, From Thales to Euclid and Volume II, From Aristarchus to Diophantus. It got positive reviews and is still used today. Ten years later, in 1931, Heath published A Manual of Greek Mathematics, a concise version of the two-volume History.
Background
Thomas Heath was a British civil servant, whose hobby was Greek mathematics (he called it a "hobby" himself). He published a number of translations of major works of Euclid, Archimedes, Apollonius of Perga and others; most are still used today.
Heath wrote in the preface to the book:
The work was begun in 1913, but the bulk of it was written, as a distraction, during the first three years of the war, the hideous course of which seemed day by day to enforce the profound truth conveyed in the answer of Plato to the Delians. When they consulted him on the problem set them by the Oracle, namely, that of duplicating the cube, he replied, 'It must be supposed, not that the god specially wished this problem solved, but that he would have the Greeks desist from war and wickedness and cultivate the Muses, so that, their passion being assuaged by philosophy and mathematics, they might live in innocent and mutually helpful intercourse with one another.'
Ten years later, in 1931, Heath published A Manual of Greek Mathematics, a concise version of the two-volume History. In a preface Heath wrote that the Manual is for "the general reader who has not lost interest in the studies of his youth", while History was written for scholars. The Manual contains some discoveries made in ten years after the publication of History, for example the new edition of Rhind Papyrus (published in 1923), some parts of then unpublished Moscow Papyrus, and decipherment of Babylonian tablets and "the newest studies" of Babylonian astronomy.

The LOTAR Unit, (), is a counter-terrorism special forces (sayeret) unit within the Israeli Defense Forces (IDF) (also known as Unit 707 or The Counter-Terror School). The name is an abbreviation of the .
It is tasked primarily with training other IDF units in the areas of counter-terrorism, the use of sniper rifles, and various small-scale and short-range warfare scenarios. The unit has also taken on several other responsibilities including the theories of camouflage, the training of special soldiers called "monkeys" (trained in climbing and rappelling), and several other training scenarios.
The LOTAR School is housed inside of Mitkan Adam (), alongside the Oketz Unit and the Oz Brigade, southeast of Tel Aviv within the Hevel Modi'in Regional Council.
History
The unit was founded by its first Commander, Amos Kotzer, in 1974. It was created, along with Yamam, a unit in the Israel Border Police, primarily in response to the Ma'alot massacre, where a failed rescue operation by Sayeret Matkal resulted in the deaths of 25 hostages, including 21 children, before the hostage takers were killed.

198 (one hundred [and] ninety-eight) is the natural number following 197 and preceding 199.
In mathematics
198 is the number of nonzero palindromes less than 104.
198 is the sum of products of terms in all partitions of the number 9.
198 is the smallest number that can be written as a sum of four positive squares in ten different ways: 198 = 12 + 22 + 72 + 122 = 12 + 42 + 92 + 102 = 22 + 32 + 42 + 132 = 22 + 32 + 82 + 112 = 22 + 52 + 52 + 122 = 22 + 72 + 82 + 92 = 32 + 32 + 62 + 122 = 32 + 52 + 82 + 102 = 42 + 52 + 62 + 112 = 62 + 72 + 72 + 82.
198 is a companion Pell number. Its corresponding Pell number is 70.
198 is the 4th term of the sequence a(n) = 10*a(n-1) - a(n-2) with a(0) = 0, a(1) = 2. This sequence has the property that for each n, if A = a(n), B = 2*a(n+1), C = 3*a(n+1) then A*B+1, A*C+1, B*C+1 are perfect squares.
198 is the first number between a twin prime pair such that product of itself by its reversal (198 x 891 = 176418) is also between a twin prime pair.
198 is a Harshad number, which means it is divisible by the sum of its digits.
198 is both the average of a twin prime pair (197, 199), and the sum of 2 successive primes (97, 101).
198 is a coordination number for hexagonal lattices, which means it is the difference between two consecutive centered hexagonal numbers. In this case, 198 is the difference between 3367 and 3169 (34th and 33rd centered hexagonal numbers), so the hexagonal spatial arrangement of 3367 has 198 dots in the border.
198 is also the 8th coordination number for cubic lattices, making it the 6th number to be part of the coordination sequences for both cubic and hexagonal lattices.
In other fields
198 is also:
The State Highway Police emergency telephone number in Brazil.
The number of ridges on a U.S. dollar coin.

Wrexham Association Football Club is a professional association football club based in Wrexham, Wales. The club competes in EFL League Two, the fourth tier of the English football league system since 2023–24, following promotion from the National League.
The club was founded in 1864, making it the oldest club in Wales and the third-oldest professional team in the world. In 1890, it joined The Combination league, before spells in the Welsh Senior League and Birmingham & District League. They remained in this division before being elected to the Football League in 1921. Wrexham would spend the next 37 years in the Third Division North until they were placed in the Third Division as part of the League re-structuring in 1958. Wrexham would subsequently fluctuate between the Third and Fourth Divisions before earning promotion to the Second Division as champions in 1978. By 1983, Wrexham had experienced two consecutive relegations to leave them back in the Fourth Division once again. In the early 21st century, Wrexham would experience severe financial issues and despite a triumph in the Football League Trophy in 2004–05, they would be relegated from the Football League for the first time in 2008. After five unsuccessful play-off attempts, Wrexham would finally win the National League in 2023 after a 15-year exile in non-League.
Wrexham have won the Welsh Cup a record 23 times, the Football League Trophy in 2005, and the FA Trophy in 2013. They have gained one promotion from the third tier, six promotions from the fourth tier, and one promotion from the fifth tier. Wrexham's record league appearance maker is Arfon Griffiths with 592 appearances, whilst their top goalscorer is Tommy Bamford with 175 league goals. Their highest recorded attendance is 34,445 for an FA Cup tie with Manchester United in 1957.
