https://en.wikipedia.org/wiki/Minerva%20Cordero | Minerva Cordero Braña is a Puerto Rican mathematician and a professor of mathematics at the University of Texas at Arlington. She is also the university's Senior Associate Dean for the College of Science, where she is responsible for the advancement of the research mission of the college. President Biden awarded her the Presidential Award for Excellence in Science, Mathematics, and Engineering Mentoring (PAESMEM) on February 8, 2022.
Early life and education
Cordero was born in Bayamón, Puerto Rico. Her mother, whose schooling stopped after the fifth grade, made education a top priority in the family home. She told her children "the best thing I can give you is an education." Cordero and her siblings would do their homework together and discussed what they learned in school each day. Cordero said, "We learned each other's subjects." Wanting to go to college, Cordero bought herself a college exam preparation book in high school and studied for the college-entrance exam. She states that her exam scores were the highest scores for her high school, Miguel Melendez Munoz High School.
Cordero attended the Universidad de Puerto Rico in Rio Piedras and received her B.S. in Mathematics in 1981. She was granted a National Science Foundation Minority Graduate Fellowship which she used to attend the University of California at Berkeley to obtain her masters in mathematics in 1983. She continued her studies at the University of Iowa, and obtained her Ph.D. in mathematics in 1989 under Norman Johnson.
Career and research
Cordero's research is in the area of finite semifields (non-associative algebras) and their associated planes (viewed affinely or projectively) in the general area of finite geometry.
After earning her Ph.D., Cordero worked as an associate and an assistant professor at Texas Tech University until 2001, when she joined the faculty at the University of Texas at Arlington. Cordero served as the Mathematical Association of America's Governor-at-Large for Minority Interests from 2008 to 2011.
Cordero's most-cited work is A survey of finite semifields. She was the Principal Investigator for a National Science Foundation grant of $2.85 million awarded to the University of Texas at Arlington in 2009 for a project that placed mathematics graduate students in Arlington public schools to enhance teaching and learning in the classrooms and to inspire students to pursue careers in STEM (Science, Technology, Engineering, and Mathematics).

https://en.wikipedia.org/wiki/Erica%20N.%20Walker | Erica Nicole Walker (born 1971) is an American mathematician and the Clifford Brewster Upton Professor of Mathematics Education at Teachers College, Columbia University, where she also serves as the Chairperson of the Department of Mathematics, Science, and Technology and as the Director of the Institute for Urban and Minority Education. Walker’s research focuses on the "social and cultural factors as well as educational policies and practices that facilitate mathematics engagement, learning and performance, especially for underserved students".
Education
Walker is originally from Atlanta, Georgia, and began learning mathematics as a preschooler from a mathematics teacher who lived next door.
As a high school student, Walker showed an aptitude for math. Encouraged by a teacher to take AP Calculus during her senior year, Walker found that "the calculus teacher was terrible....so we students all taught each other after class." She realized that she enjoyed teaching math to her friends. That experience led Walker to major in mathematics in college and begin her career teaching mathematics in public school.
Walker earned a B.S. (cum laude) in mathematics at Birmingham–Southern College. She obtained a Master of Education in Mathematics Education at Wake Forest University. After obtaining her graduate degree, Walker taught high school mathematics in Atlanta, Georgia. Her teaching experience and earlier observation of few African-American students in upper level math courses during college led to an interest in and intent to encourage more African-American students to take advanced math classes, as well as to the conference of several teaching awards.
Walker received her Doctor of Education from Harvard University's Graduate School of Education in 2001. At Harvard, she furthered her studies and research in the "experience of students of color in math classes." Her dissertation, "On Time and Off Track: Advanced Mathematics Course-Taking Among High School Students," examined the experience of high school students taking math classes. Specifically, who continues to upper level math, who stops, and why.
Academic career
Walker was a postdoctoral fellow at Teachers College, Columbia University from 2001 to 2002.
She has been a faculty member at Teachers College since 2002. Her primary research interests are racial and gender equity in mathematics education, student persistence in advanced mathematics, and mathematics educational policy. She is the author of two books and has contributed to a number of scholarly journals.
In 2017, she became director of the Institute for Urban and Minority Education at Teachers College.
Recognized by the National Association of Mathematicians and the Association for Women in Mathematics for her scholarship and practice, Walker collaborates with teachers, schools, districts, organizations, and media outlets to promote mathematics excellence and equity for young people.

https://en.wikipedia.org/wiki/Average%20variance%20extracted | In statistics (classical test theory), average variance extracted (AVE) is a measure of the amount of variance that is captured by a construct in relation to the amount of variance due to measurement error.
History
The average variance extracted was first proposed by Fornell & Larcker (1981).
Calculation
The average variance extracted can be calculated as follows:
Here, is the number of items, the factor loading of item and the variance of the error of item .
Role for assessing discriminant validity
The average variance extracted has often been used to assess discriminant validity based on the following "rule of thumb": the positive square root of the AVE for each of the latent variables should be higher than the highest correlation with any other latent variable. If that is the case, discriminant validity is established at the construct level. This rule is known as Fornell–Larcker criterion. However, in simulation models this criterion did not prove reliable for composite-based structural equation models (e.g., PLS-PM), but indeed proved to be reliable for factor-based structural equation models (e.g., Amos, PLSF-SEM).
Related coefficients
Related coefficients are tau-equivalent reliability (; traditionally known as "Cronbach's ") and congeneric reliability (; also known as composite reliability) which can be used to evaluate the reliability of tau-equivalent and congeneric measurement models, respectively.

https://en.wikipedia.org/wiki/Leinster%20group | In mathematics, a Leinster group is a finite group whose order equals the sum of the orders of its proper normal subgroups.
The Leinster groups are named after Tom Leinster, a mathematician at the University of Edinburgh, who wrote about them in a paper written in 1996 but not published until 2001. He called them "perfect groups" and later "immaculate groups",
but they were renamed as the Leinster groups by because "perfect group" already had a different meaning (a group that equals its commutator subgroup).
Leinster groups give a group-theoretic way of analyzing the perfect numbers and of approaching the still-unsolved problem of the existence of odd perfect numbers.
For a cyclic group, the orders of the subgroups are just the divisors of the order of the group,
so a cyclic group is a Leinster group if and only if its order is a perfect number. More strongly, as Leinster proved, an abelian group is a Leinster group if and only if it is a cyclic group whose order is a perfect number. Moreover Leinster showed that dihedral Leinster groups are in one-to-one correspondence with odd perfect numbers, so the existence of odd perfect numbers is equivalent to the existence of dihedral Leinster groups.
Examples
The cyclic groups whose order is a perfect number are Leinster groups.
It is possible for a non-abelian Leinster group to have odd order; an example of order 355433039577 was constructed by François Brunault.
Other examples of non-abelian Leinster groups include certain groups of the form , where is an alternating group and is a cyclic group. For instance, the groups , , and are Leinster groups. The same examples can also be constructed with symmetric groups, i.e., groups of the form , such as .
The possible orders of Leinster groups form the integer sequence
6, 12, 28, 30, 56, 360, 364, 380, 496, 760, 792, 900, 992, 1224, ...
It is unknown whether there are infinitely many Leinster groups.
Properties
There are no Leinster groups that are symmetric or alternating.
There is no Leinster group of order p2q2 where p, q are primes.
No finite semi-simple group is Leinster.
No p-group can be a Leinster group.
All abelian Leinster groups are cyclic with order equal to a perfect number.

During World War II he was part of a group of five mathematicians, which was recruited by the military cryptanalyst Wilhelm Fenner, and which included Ernst Witt, Georg Aumann, Oswald Teichmueller and Johann Friedrich Schultze, to form the backbone of the new mathematical research department in the late 1930s, which would eventually be called Section IVc of Cipher Department of the High Command of the Wehrmacht. (abbr. OKW/Chi). The group was led by the German professor of mathematics Wolfgang Franz.
Life
Alexander Aigner was the son of noted medical doctor Oktavia Aigner-Rollett and anatomist Walter Aigner (1878–1950). He was the grandson of noted physiologist and histologist of Alexander Rollett. He studied mathematics and physics in at the University of Graz. In 1936, he was put forward by Dr. Karl Brauner for promotion to Dr. Phil, with Dr. Tonio Rella advising, with a thesis titled: Mathematical treatment of the hermit game in the plane and in space. About the possibility of in square bodies (German: Mathematische Behandlung des Einsiedlerspieles in der Ebene und im Raume. Über die Möglichkeit von in quadratischen Körpern). He was offered a position as assistant at the 2nd Chair (Lehrkanzel) for Mathematics at Karl Franzens University. Aigner published articles in the journal Deutsche Mathematik. During World War II, he was recruited along with a number of other mathematicians to make up the backbone of a new cipher bureau for the German Army. He would eventually work at the mathematical research department IV/Section IVc of OKW/Chi under Erich Hüttenhain in the deciphering of complex foreign encryption systems.
In 1947 he qualified as a professor at the Karl Franzens University in Graz, where he received an assistant position from Georg Kantz. In 1957, he became an extraordinary professor (Academic ranks in Germany) and finally a full professor. Even after becoming professor emeritus in 1979 he continued to give lectures about number theory, his primary focus. In addition to his professional activities, he also developed a literary interest. He was a member of the Styrian Writers' Union and the confederation of Styrian home poets. After two volumes of poetry, in 1978 he published a collection of cheerful mathematical poems titled Tangents to the Frohsinn (Tangenten an den Frohsinn), a special edition of the reports of the Mathematical-Statistical Section at the Research Center Graz.

https://en.wikipedia.org/wiki/List%20of%20Major%20League%20Baseball%20career%20putouts%20as%20a%20right%20fielder%20leaders | In baseball statistics, a putout (denoted by PO or fly out when appropriate) is given to a defensive player who records an out by tagging a runner with the ball when he is not touching a base, catching a batted or thrown ball and tagging a base to put out a batter or runner (a force out), catching a thrown ball and tagging a base to record an out on an appeal play, catching a third strike (a strikeout), catching a batted ball on the fly (a fly out), or being positioned closest to a runner called out for interference. The right fielder (RF) is one of the three outfielders, the defensive positions in baseball farthest from the batter. The right field is the area of the outfield to the right of a person standing at home plate and facing toward the pitcher's mound. The outfielders must try to catch long fly balls before they hit the ground or to quickly catch or retrieve and return to the infield any other balls entering the outfield. The right fielder must also be adept at navigating the area of the right field where the foul line approaches the corner of the playing field and the walls of the seating areas. Being the outfielder farthest from third base, the right fielder often has to make longer throws than the other outfielders to throw out runners advancing around the bases, so they often have the strongest or most accurate throwing arm. The right fielder normally plays behind the second baseman and first baseman, who play in or near the infield; unlike catchers and most infielders (excepting first basemen), who are virtually exclusively right-handed, right fielders can be either right- or left-handed. In the scoring system used to record defensive plays, the right fielder is assigned the number 9, the highest number.
The overwhelming majority of putouts recorded by right fielders, almost to exclusivity, result from catching fly balls. However, in extraordinary circumstances, an outfielder may record a putout by receiving a throw to force out or tag out a runner while covering a base if one or more infielders are out of position to retrieve an errant throw, or by tagging a runner stranded between bases in a rundown play; however, even in such circumstances, outfielders will more typically act as a backup to infielders than cover a base themselves. Historically, putout totals for outfielders rose after 1920 with the end of the dead-ball era; the same circumstances which had kept home run totals low, such as overused baseballs and legal adulterations including the spitball, had similarly hindered the type of power hitting which lent itself to long fly balls. As strikeout totals have risen in baseball in recent decades, the frequency of other defensive outs including flyouts has declined; as a result, putout totals for outfielders have generally declined, but right fielders have largely defied this trend. Eight of the top nine players, and 17 of the top 20, were active entirely after 1950. Through the 2022 season, none of the top 251 single-season |
https://en.wikipedia.org/wiki/Elongated%20gyrobifastigium | In geometry, the elongated gyrobifastigium or gabled rhombohedron is a space-filling octahedron with 4 rectangles and 4 right-angled pentagonal faces.
Name
The first name is from the regular-faced gyrobifastigium but elongated with 4 triangles expanded into pentagons. The name of the gyrobifastigium comes from the Latin fastigium, meaning a sloping roof. In the standard naming convention of the Johnson solids, bi- means two solids connected at their bases, and gyro- means the two halves are twisted with respect to each other. The gyrobifastigium is first in a series of gyrobicupola, so this solid can also be called an elongated digonal gyrobicupola. Geometrically it can also be constructed as the dual of a digonal gyrobianticupola. This construction is space-filling.
The second name, gabled rhombohedron, is from Michael Goldberg's paper on space-filling octahedra, model 8-VI, the 6th of at least 49 space-filling octahedra. A gable is the triangular portion of a wall between the edges of intersecting roof pitches.
Geometry
The highest symmetry forms are D2d, order 8, while if the underlying rectangular cuboid is distorted into a rhombohedron, the symmetry is reduced to 2-fold rotational symmetry, C2, order 2.
It has all 3-valence vertices and its dual has all triangular faces, including the snub disphenoid as a deltahedron with all equilateral triangles. However the dual of the snub disphenoid is not space-filling because the pentagons are not right-angled.
Related figures
The elongated gyrobifastigium is the cell of the isochoric tridecachoron, a polychoron constructed from the dual of the 13-5 step prism, which has a snub disphenoid vertex figure.
Variations
A topologically distinct elongated gyrobifastigium has square and equilateral triangle faces, seen as 2 triangular prisms augmented to a central cube. This is a failed Johnson solid for not being strictly convex.
This is also a space-filling polyhedron, and matches the geometry of the gyroelongated triangular prismatic honeycomb if the elongated gyrobifastigium are dissected back into cubes and triangular prisms.
The elongated gyrobifastigium must be based on a rectangular cuboid or rhombohedron to fill-space, while the angle of the roof is free, including allowing concave forms. If the roof has zero angle, the geometry becomes a cube or rectangular cuboid.
The pentagons can also be made regular and the rectangles become trapezoids, and it will no longer be space-filling.
Honeycomb
Like the gyrobifastigium, it can self-tessellate space. Polyhedra are tessellated by translation in the plane, and are stacked with alternate orientations. The cross section of the polyhedron must be square or rhombic, while the roof angle is free, and can be negative, making a concave polyhedron. Rhombic forms require chiral (mirror image) polyhedral pairs to be space-filling.

https://en.wikipedia.org/wiki/Kaisa%20Matom%C3%A4ki | Kaisa Sofia Matomäki (born April 30, 1985) is a Finnish mathematician specializing in number theory. Since September 2015, she has been working as an Academic Research Fellow in the Department of Mathematics and Statistics, University of Turku, Turku, Finland. Her research includes results on the distribution of multiplicative functions over short intervals of numbers; for instance, she showed that the values of the Möbius function are evenly divided between +1 and −1 over short intervals. These results, in turn, were among the tools used by Terence Tao to prove the Erdős discrepancy problem.
Awards and honors
Kaisa Matomäki, along with Maksym Radziwill of McGill University, Canada, was awarded the SASTRA Ramanujan Prize for 2016. The Prize was established in 2005 and is awarded annually for outstanding contributions by young mathematicians to areas influenced by Srinivasa Ramanujan.
The citation for the 2016 SASTRA Ramanujan Prize is as follows: "Kaisa Matomäki and Maksym Radziwill are jointly awarded the 2016 SASTRA Ramanujan Prize for their deep and far reaching contributions to several important problems in diverse areas of number theory and especially for their spectacular collaboration which is revolutionizing the subject. The prize recognizes that in making significant improvements over the works of earlier stalwarts on long standing problems, they have introduced a number of innovative techniques. The prize especially recognizes their collaboration starting with their 2015 joint paper in Geometric and Functional Analysis which led to their 2016 paper in the Annals of Mathematics in which they obtain amazing results on multiplicative functions in short intervals, and in particular a stunning result on the parity of the Liouville lambda function on almost all short intervals - a paper that is expected to change the subject of multiplicative functions in a major way. The prize notes also the very recent joint paper of Matomäki, Radziwill and Tao announcing a significant advance in the case k = 3 towards a conjecture of Chowla on the values of the lambda function on sets of k consecutive integers. Finally the prize notes, that Matomäki and Radziwill, through their impressive array of deep results and the powerful new techniques they have introduced, will strongly influence the development of analytic number theory in the future."
With Radziwill, she is one of five winners of the 2019 New Horizons Prize for Early-Career Achievement in Mathematics, associated with the Breakthrough Prize in Mathematics. She is one of the 2020 winners of the EMS Prize. She was awarded the 2021 Ruth Lyttle Satter Prize by the American Mathematical Society "for her work (much of it joint with Maksym Radziwiłł) opening up the field of multiplicative functions in short intervals in a completely unexpected and very fruitful way, and in particular in their breakthrough paper, 'Multiplicative Functions in Short Intervals' (Annals of Mathematics 183 2016, 1015–1056) |

https://en.wikipedia.org/wiki/Visual%20information%20fidelity | Visual information fidelity (VIF) is a full reference image quality assessment index based on natural scene statistics and the notion of image information extracted by the human visual system. It was developed by Hamid R Sheikh and Alan Bovik at the Laboratory for Image and Video Engineering (LIVE) at the University of Texas at Austin in 2006. It is deployed in the core of the Netflix VMAF video quality monitoring system, which controls the picture quality of all encoded videos streamed by Netflix.
Model overview
Images and videos of the three-dimensional visual environments come from a common class: the class of natural scenes. Natural scenes from a tiny subspace in the space of all possible signals, and researchers have developed sophisticated models to characterize these statistics. Most real-world distortion processes disturb these statistics and make the image or video signals unnatural. The VIF index employs natural scene statistical (NSS) models in conjunction with a distortion (channel) model to quantify the information shared between the test and the reference images. Further, the VIF index is based on the hypothesis that this shared information is an aspect of fidelity that relates well with visual quality. In contrast to prior approaches based on human visual system (HVS) error-sensitivity and measurement of structure, this statistical approach used in an information-theoretic setting, yields a full reference (FR) quality assessment (QA) method that does not rely on any HVS or viewing geometry parameter, nor any constants requiring optimization, and yet is competitive with state of the art QA methods.
Specifically, the reference image is modeled as being the output of a stochastic `natural' source that passes through the HVS channel and is processed later by the brain. The information content of the reference image is quantified as being the mutual information between the input and output of the HVS channel. This is the information that the brain could ideally extract from the output of the HVS. The same measure is then quantified in the presence of an image distortion channel that distorts the output of the natural source before it passes through the HVS channel, thereby measuring the information that the brain could ideally extract from the test image. This is shown pictorially in Figure 1. The two information measures are then combined to form a visual information fidelity measure that relates visual quality to relative image information.

https://en.wikipedia.org/wiki/Exponential%20response%20formula | In mathematics, the exponential response formula (ERF), also known as exponential response and complex replacement, is a method used to find a particular solution of a non-homogeneous linear ordinary differential equation of any order. The exponential response formula is applicable to non-homogeneous linear ordinary differential equations with constant coefficients if the function is polynomial, sinusoidal, exponential or the combination of the three. The general solution of a non-homogeneous linear ordinary differential equation is a superposition of the general solution of the associated homogeneous ODE and a particular solution to the non-homogeneous ODE.
Alternative methods for solving ordinary differential equations of higher order are method of undetermined coefficients and method of variation of parameters.
Context and method
Applicability
The ERF method of finding a particular solution of a non-homogeneous differential equation is applicable if the non-homogeneous equation is or could be transformed to form ; where are real or complex numbers and is homogeneous linear differential equation of any order. Then, the exponential response formula can be applied to each term of the right side of such equation. Due to linearity, the exponential response formula can be applied as long as the right side has terms, which are added together by the superposition principle.
Complex replacement
Complex replacement is a method of converting a non-homogeneous term of equation into a complex exponential function, which makes a given differential equation a complex exponential.
Consider differential equation .
To make complex replacement, Euler's formula can be used;
Therefore, given differential equation changes to . The solution of the complex differential equation can be found as , from which the real part is the solution of the original equation.
Complex replacement is used for solving differential equations when the non-homogeneous term is expressed in terms of a sinusoidal function or an exponential function, which can be converted into a complex exponential function differentiation and integration. Such complex exponential function is easier to manipulate than the original function.
When the non-homogeneous term is expressed as an exponential function, the ERF method or the undetermined coefficients method can be used to find a particular solution. If non-homogeneous terms can not be transformed to complex exponential function, then the Lagrange method of variation of parameters can be used to find solutions.
Linear time-invariant operator
The differential equations are important in simulating natural phenomena. In particular, there are numerous phenomena described as high order linear differential equations, for example the spring vibration, LRC circuit, beam deflection, signal processing, control theory and LTI systems with feedback loops.
Mathematically, the system is time-invariant if whenever the input has response then for |

https://en.wikipedia.org/wiki/Mers%20Kutt | Merslau "Mers" Kutt CM (born 1933) is a Canadian inventor, businessman and educator. He is a former professor of mathematics at Queen's University. Through his company, Micro Computer Machines, he is the developer of the world's first keyboard-based portable microcomputer.
Early life
Kutt was born in Winnipeg, Manitoba. He graduated in 1956 from the University of Toronto with a degree in mathematics and physics.
Career
After employment in industry at Phillips, IBM and Honeywell, Kutt worked as a professor of mathematics at Queen's University in Kingston, Ontario during the 1960s. He served as president of the Canadian Information Processing Society, and was director of the University's computing centre. In 1968, after observing the punched card-based input systems in use there at the time to program its mainframe, he partnered with Donald Pamenter to start a company, Consolidated Computer Inc., and produced "Key-Edit", a terminal with a one-line of display, which both streamlined and reduced the cost of the process. This product was the first of its kind, and was sold and used in many countries during the next few years distributed by International Computers Limited and Fujitsu.
By 1971, Kutt been forced out of Consolidated's management, and he formed two more companies, Micro Computer Machines and Kutt Systems Inc. As president of these companies he directed the design and manufacture in 1973 of the MCM/70, the world's first complete microprocessor-based, portable personal computer. The device, based on the Intel 8008 processor, was used to edit and execute programs using the APL programming language.
The MCM/70 technical specifications were overtaken by products from companies with larger development and marketing budgets, and by 1982 the product was no longer in production.
In 1976 Kutt started up another Toronto company, All Computers Inc., which developed improvements to several Intel processors. By 2004, Kutt was the company's only employee; that year he sued Intel, alleging that his patented circuitry had been included in Pentium processors. The suit was dismissed in 2005.
In 2006, Kutt was inducted into the Order of Canada.

https://en.wikipedia.org/wiki/Kuramoto%E2%80%93Sivashinsky%20equation | In mathematics, the Kuramoto–Sivashinsky equation (also called the KS equation or flame equation) is a fourth-order nonlinear partial differential equation. It is named after Yoshiki Kuramoto and Gregory Sivashinsky, who derived the equation in the late 1970s to model the diffusive–thermal instabilities in a laminar flame front. The equation was independelty derived by G. M. Homsy and A. A. Nepomnyashchii in 1974, in connection with the stability of liquid film on an inclined plane and by R. E. LaQuey et. al. in 1975 in connection with trapped-ion instability. The Kuramoto–Sivashinsky equation is known for its chaotic behavior.
Definition
The 1d version of the Kuramoto–Sivashinsky equation is
An alternate form is
obtained by differentiating with respect to and substituting . This is the form used in fluid dynamics applications.
The Kuramoto–Sivashinsky equation can also be generalized to higher dimensions. In spatially periodic domains, one possibility is
where is the Laplace operator, and is the biharmonic operator.
Properties
The Cauchy problem for the 1d Kuramoto–Sivashinsky equation is well-posed in the sense of Hadamard—that is, for given initial data , there exists a unique solution that depends continuously on the initial data.
The 1d Kuramoto–Sivashinsky equation possesses Galilean invariance—that is, if is a solution, then so is , where is an arbitrary constant. Physically, since is a velocity, this change of variable describes a transformation into a frame that is moving with constant relative velocity . On a periodic domain, the equation also has a reflection symmetry: if is a solution, then is also a solution.
Solutions
Solutions of the Kuramoto–Sivashinsky equation possess rich dynamical characteristics. Considered on a periodic domain , the dynamics undergoes a series of bifurcations as the domain size is increased, culminating in the onset of chaotic behavior. Depending on the value of , solutions may include equilibria, relative equilibria, and traveling waves—all of which typically become dynamically unstable as is increased. In particular, the transition to chaos occurs by a cascade of period-doubling bifurcations.
Applications
Applications of the Kuramoto–Sivashinsky equation extend beyond its original context of flame propagation and reaction–diffusion systems. These additional applications include flows in pipes and at interfaces, plasmas, chemical reaction dynamics, and models of ion-sputtered surfaces.

https://en.wikipedia.org/wiki/Kempe%27s%20universality%20theorem | In 1876 Alfred B. Kempe published his article On a General Method of describing Plane Curves of the nth degree by Linkwork, which showed that for an arbitrary algebraic plane curve a linkage can be constructed that draws the curve. This direct connection between linkages and algebraic curves has been named Kempe's universality theorem that any bounded subset of an algebraic curve may be traced out by the motion of one of the joints in a suitably chosen linkage. Kempe's proof was flawed and the first complete proof was provided in 2002 based on his ideas.
This theorem has been popularized by describing it as saying, "One can design a linkage which will sign your name!"
Kempe recognized that his results demonstrate the existence of a drawing linkage but it would not be practical. He states
It is hardly necessary to add, that this method would not be practically useful on account of the complexity of the linkwork employed, a necessary consequence of the perfect generality of the demonstration.
He then calls for the "mathematical artist" to find simpler ways to achieve this result:
The method has, however, an interest, as showing that there is a way of drawing any given case; and the variety of methods of expressing particular functions that have already been discovered renders it in the highest degree probable that in every case a simpler method can be found. There is still, however, a wide field open to the mathematical artist to discover the simplest linkworks that will describe particular curves.
A series of animations demonstrating the linkwork that results from Kempe's universality theorem are available for the parabola, self-intersecting cubic, smooth elliptic cubic and the trifolium curves.
Simpler drawing linkages
Several approaches have been taken to simplify the drawing linkages that result from Kempe's universality theorem. Some of the complexity arises from the linkages Kempe used to perform addition and subtraction of two angles, the multiplication of an angle by a constant, and translation of the rotation of a link in one location to a rotation of a second link at another location. Kempe called these linkages additor, reversor, multiplicator and translator linkages, respectively. The drawing linkage can be simplified by using bevel gear differentials to add and subtract angles, gear trains to multiply angles and belt or cable drives to translate rotation angles.
Another source of complexity is the generality of Kempe's application to all algebraic curves. By focusing on parameterized algebraic curves, dual quaternion algebra can be used to factor the motion polynomial and obtain a drawing linkage. This has been extended to provide movement of the end-effector, but again for parameterized curves.
Specializing the curves to those defined by trigonometric polynomials has provided another way to obtain simpler drawing linkages. Bezier curves can be written in the form of trigonometric polynomials therefore a linkage syste |

If R is a ring, then R is an associative algebra over its center. Conversely, if R is an associative algebra over a commutative subring S, then S is a subring of the center of R, and if S happens to be the center of R, then the algebra R is called a central algebra.
Examples
The center of a commutative ring R is R itself.
The center of a skew-field is a field.
The center of the (full) matrix ring with entries in a commutative ring R consists of R-scalar multiples of the identity matrix.
Let F be a field extension of a field k, and R an algebra over k. Then .
The center of the universal enveloping algebra of a Lie algebra plays an important role in the representation theory of Lie algebras. For example, a Casimir element is an element of such a center that is used to analyze Lie algebra representations. See also: Harish-Chandra isomorphism.

https://en.wikipedia.org/wiki/K-synchronized%20sequence | In mathematics and theoretical computer science, a k-synchronized sequence is an infinite sequence of terms s(n) characterized by a finite automaton taking as input two strings m and n, each expressed in some fixed base k, and accepting if m = s(n). The class of k-synchronized sequences lies between the classes of k-automatic sequences and k-regular sequences.
Definitions
As relations
Let Σ be an alphabet of k symbols where k ≥ 2, and let [n]k denote the base-k representation of some number n. Given r ≥ 2, a subset R of is k-synchronized if the relation {([n1]k, ..., [nr]k)} is a right-synchronized rational relation over Σ∗ × ... × Σ∗, where (n1, ..., nr) R.
Language-theoretic
Let n ≥ 0 be a natural number and let f: be a map, where both n and f(n) are expressed in base k. The sequence f(n) is k-synchronized if the language of pairs is regular.
History
The class of k-synchronized sequences was introduced by Carpi and Maggi.
Example
Subword complexity
Given a k-automatic sequence s(n) and an infinite string S = s(1)s(2)..., let ρS(n) denote the subword complexity of S; that is, the number of distinct subwords of length n in S. Goč, Schaeffer, and Shallit demonstrated that there exists a finite automaton accepting the language
This automaton guesses the endpoints of every contiguous block of symbols in S and verifies that each subword of length n starting within a given block is novel while all other subwords are not. It then verifies that m is the sum of the sizes of the blocks. Since the pair (n, m)k is accepted by this automaton, the subword complexity function of the k-automatic sequence s(n) is k-synchronized.
Properties
k-synchronized sequences exhibit a number of interesting properties. A non-exhaustive list of these properties is presented below.
Every k-synchronized sequence is k-regular.
Every k-automatic sequence is k-synchronized. To be precise, a sequence s(n) is k-automatic if and only if s(n) is k-synchronized and s(n) takes on finitely many terms. This is an immediate consequence of both the above property and the fact that every k-regular sequence taking on finitely many terms is k-automatic.
The class of k-synchronized sequences is closed under termwise sum and termwise composition.
The terms of any k-synchronized sequence have a linear growth rate.
If s(n) is a k-synchronized sequence, then both the subword complexity of s(n) and the palindromic complexity of s(n) (similar to subword complexity, but for distinct palindromes) are k-regular sequences.

https://en.wikipedia.org/wiki/PR1ME%20Mathematics%20Teaching%20Programme | PR1ME Mathematics teaching programme (PR1ME) is created for the primary or elementary grades and was first introduced in 2014 by Scholastic. It is adopted by schools in multiple countries such as Philippines, Australia, New Zealand and Mexico. PR1ME is a programme based on the Mathematics teaching and learning practices of Singapore, Hong Kong and Republic of Korea, which have consistently performed strongly in international mathematics studies such as the Trends in International Mathematics and Science Study (TIMSS) and Organisation for Economic Co-operation and Development's Programme for International Student Assessment (PISA). This programme was developed in collaboration with the Ministry of Education (MOE), Singapore and is adapted from the Primary Mathematics Project developed by MOE.
Aim of programme
The main aim of PR1ME is to nurture young learners and help them build strong mathematical foundation skills. It is based on the five practices listed in the pentagon, which is the framework for mathematics instruction developed by the MOE with problem solving at its core.
Problem solving is central: Developing problem solving skills should address both the process and the method of solving problems.
Development of metacognition and mathematical thinking skills: Thinking mathematically is a conscious habit and should be developed through consistent use in many contexts.
Concrete-Pictorial-Abstract Approach: Develops deep conceptual understanding through making meaningful connections between principles and symbols through concrete activities and visual representation, ensuring deep and long-lasting conceptual understanding.
Process of learning mathematics: Learning to mastery involves a focus on concept development and understanding mathematical relationships, and learning to inquire, communicate, reason, conceptualize, formulate and solve mathematical problems, appreciate the beauty of mathematics and apply mathematics in different contexts.
Consistent formative assessment: Assessment is a routine part of the on-going classroom activity.
Approach
PR1ME's pedagogical approach and instructional design revolve around problem solving, and the development of metacognition and mathematical thinking skills.
Problem solving is central with an emphasis on both the process and strategies, including the Bar Model method. Process helps to build good habits for approaching mathematical problems of all levels of difficulty (UPAC – Understand, Plan, Answer, Check, Mind Stretchers) while strategies equip students to tackle different types of word problems (Heuristics, Mind Stretchers).
The Bar Model method allows students to solve complex word problems using visual representation. Mathematical reasoning and problem posing allows students to be aware of their thought process, enabling them to become proficient problem solvers. Deep conceptual understanding is achieved through systematic teaching of mathematical concepts with a topic taught in-depth and ov |

https://en.wikipedia.org/wiki/John%20Wood%20%28mathematician%29 | John Wood (c. 1775–1822) was a professor of mathematics at the College of William & Mary, political writer, and cartographer, who tutored the grandchildren of Thomas Jefferson.
Life
A native of Scotland, Wood spent much of his early years in France and Switzerland before immigrating to New York City in 1800. Upon arriving in the United States, he soon met Aaron Burr and wrote a number of pamphlets supporting Burr's political stance. One of Wood’s efforts, The History of the Administration of John Adams was deemed so controversial that Burr unsuccessfully attempted to suppress it. Wood briefly lived in Kentucky in 1806 and resided thereafter in Richmond, Virginia. He received his education from the College of William & Mary, where he graduated in 1807. A close acquaintance of Thomas Jefferson, Wood taught his grandson, Thomas Jefferson Randolph, at the Louis H. Girardin Academy from 1809 to 1810. He continued to pursue his own mathematical and scientific interests, and subsequently obtained a professorial appointment at the College of William & Mary in 1812. In 1817 he tutored another of Thomas Jefferson's grandsons, Francis Eppes, and began to map the rivers of the Tidewater region. Wood unsuccessfully sought a professorship position at the newly established University of Virginia, but received a contract with the Commonwealth of Virginia in 1819 to produce maps of all the counties and a general state map, completing ninety-six of the county maps before his death in 1822.
During his time as a cartographer, Wood obtained a vocabulary of the Nottoway language from Edith Turner, styled as the "queen" of the Nottoway (Cheroenhaka) people and the last known speaker of the language, on March 4, 1820. Wood subsequently sent a copy of the vocabulary to Thomas Jefferson, who forwarded the lexicon to Peter S. Du Ponceau. Wood initially, and incorrectly, assumed a relationship between Nottoway and Powhatan, after which Du Ponceau correctly identified Nottoway as an Iroquoian language. The vocabulary collected by Wood accounts for the majority of lexical data we currently have of Nottoway.

https://en.wikipedia.org/wiki/Starlike%20tree | In the area of mathematics known as graph theory, a tree is said to be starlike if it has exactly one vertex of degree greater than 2. This high-degree vertex is the root and a starlike tree is obtained by attaching at least three linear graphs to this central vertex.
Properties
Two finite starlike trees are isospectral, i.e. their graph Laplacians have the same spectra, if and only if they are isomorphic. The graph Laplacian has always only one eigenvalue equal or greater than 4.

https://en.wikipedia.org/wiki/Yakov%20Pesin | Yakov Borisovich Pesin () was born in Moscow, Russia (former USSR) on December 12, 1946. Pesin is currently a Distinguished Professor in the Department of Mathematics and the Director of the Anatole Katok Center for Dynamical Systems and Geometry at the Pennsylvania State University (PSU). His primary areas of research are the theory of dynamical systems with an emphasis on smooth ergodic theory, dimension theory in dynamical systems, and Riemannian geometry, as well as mathematical and statistical physics.
Professional life and education
Pesin became interested in mathematics in school but his real involvement began when he entered the boarding school with emphasis on teaching physics and mathematics that was organized by Andrei Kolmogorov. Following his graduation of the school (with honors) in 1965, he successfully passed entry exams to the Department of Mechanics and Mathematics (or "Mech-Mat") of Moscow State University. Pesin graduated from Moscow State University (also with honors) in 1970, receiving a master's degree in mathematics. His master thesis advisor was Yakov Sinai.
Pesin naturally wanted to pursue a PhD in mathematics but faced significant challenges due to the oppressive nature and anti-Semitic policies of the Soviet regime. Thus, he was not permitted to continue his study at the university graduate school and was subsequently assigned to work at a research institute in Moscow (for a more complete historical account of the anti-Semitic sentiment in the Soviet mathematics establishment during this period see the article).
Since Pesin always dreamed to be a "pure" mathematician, under the circumstances, he chose to combine his work at the institute with his after-hours research in mathematics and within a few years after graduation, he made a number of outstanding breakthroughs in the theory of smooth dynamical systems. His research at this time was conducted under the supervision of his PhD advisor, Dmitry Anosov, and also Anatole Katok.
In 1989 Pesin immigrated to the United States with his family. He first worked as a visiting Professor in the Department of Mathematics at the University of Chicago before getting the position of Full Professor at Penn State University. In 2003 Pesin received the title of Distinguished Professor of mathematics.
Yakov Pesin is married to Natasha Pesin who while in Russia worked for several years as a senior editor in the division of mathematics at the "Prosvechenie" ("Education") Publishing House in Moscow. After moving to the US she started a new career as a ceramicist (see her artworks at www.natashapesin.com).
Yakov Pesin also has two daughters, Elena and Irina who reside in the US.
Research accomplishments
Yakov Pesin is famous for several fundamental discoveries in the theory of dynamical systems (relevant references can be found on Pesin's website).

https://en.wikipedia.org/wiki/Information%20Processing%20in%20Medical%20Imaging | Information Processing in Medical Imaging, or IPMI, is a conference held every two years focused on the fields of applied mathematics, computer science, image processing and image analysis (particularly of medical images); applied results in neuroscience, cardiology, and microscopy are also frequently considered. IPMI is the longest standing conference focused on medical images having first met, organized by Dr. Francois Erbsmann, in Brussels in 1969. IPMI 2021 is scheduled to be held in Bornholm, Denmark in June 2021.
History
The Information Processing in Medical Imaging conference – IPMI - was first organized by Francois Erbsmann and collaborators in Brussels in 1969. That first conference was held under the title, “Information Processing in Scintigraphy” as at the time the meeting was focused on restoration of those images derived by nuclear medicine. Since that first instance, the conference has successfully met every two years. The third instance of the meeting, organized by Stephen Pizer and Charles Metz, was its first appearance in the United States and since that occasion IPMI has alternated its venue between the U.S. and Europe. It was the 1977 meeting organized by Randy Brill in Nashville that first used the name IPMI to reflect the broadening community of physicists, mathematicians, computer scientists, and biologists interested in medical image computing in its many manifestations and applications who now contributed to the meeting. Commemorating his contribution as the conference founder, beginning with IPMI 1987 the Francois Erbsmann prize is awarded by the IPMI board each conference to one young investigator for outstanding contribution to the field. This investigator must have given their first oral presentation at the current IPMI.
Standing with tradition, IPMI includes a single track of presentations on novel methodology wherein speakers are allotted sufficient time to describe their contributions in thorough detail. Discussions following each presentation have no time-limit permitting stimulating debate and resolution of any questions or comments regarding the work, alternatives to it, additional possible applications, etc. Further, the paper associated with each presentation is assigned a study-group of attendees in advance rendering a portion of the community prepared to provide real time peer discussion in high technical detail. Study groups often pair younger researchers with field experts encouraging an exchange of experience and new ideas. Often, discussions and debates are continued through meals and social activities uniting the community through vigorous evaluation of avant-garde developments in medical imaging. To permit such depth the conference is limited to a maximum of 120 participants.
Reflecting its focus on depth and community, IPMI is often held in a relatively small and sometimes remote location. Attendees are accommodated together in collective housing in campus or university dorms, meals are typically |

https://en.wikipedia.org/wiki/Ten-of-diamonds%20decahedron | In geometry, the ten-of-diamonds decahedron is a space-filling polyhedron with 10 faces, 2 opposite rhombi with orthogonal major axes, connected by 8 identical isosceles triangle faces. Although it is convex, it is not a Johnson solid because its faces are not composed entirely of regular polygons. Michael Goldberg named it after a playing card, as a 10-faced polyhedron with two opposite rhombic (diamond-shaped) faces. He catalogued it in a 1982 paper as 10-II, the second in a list of 26 known space-filling decahedra.
Coordinates
If the space-filling polyhedron is placed in a 3-D coordinate grid, the coordinates for the 8 vertices can be given as: (0, ±2, −1), (±2, 0, 1), (±1, 0, −1), (0, ±1, 1).
Symmetry
The ten-of-diamonds has D2d symmetry, which projects as order-4 dihedral (square) symmetry in two dimensions. It can be seen as a triakis tetrahedron, with two pairs of coplanar triangles merged into rhombic faces. The dual is similar to a truncated tetrahedron, except two edges from the original tetrahedron are reduced to zero length making pentagonal faces. The dual polyhedra can be called a skew-truncated tetragonal disphenoid, where 2 edges along the symmetry axis completely truncated down to the edge midpoint.
Honeycomb
The ten-of-diamonds is used in the honeycomb with Coxeter diagram , being the dual of an alternated bitruncated cubic honeycomb, . Since the alternated bitruncated cubic honeycomb fills space by pyritohedral icosahedra, , and tetragonal disphenoidal tetrahedra, vertex figures of this honeycomb are their duals – pyritohedra, and tetragonal disphenoids.
Cells can be seen as the cells of the tetragonal disphenoid honeycomb, , with alternate cells removed and augmented into neighboring cells by a center vertex. The rhombic faces in the honeycomb are aligned along 3 orthogonal planes.
Related space-filling polyhedra
The ten-of-diamonds can be dissected in an octagonal cross-section between the two rhombic faces. It is a decahedron with 12 vertices, 20 edges, and 10 faces (4 triangles, 4 trapezoids, 1 rhombus, and 1 isotoxal octagon). Michael Goldberg labels this polyhedron 10-XXV, the 25th in a list of space-filling decahedra.
The ten-of-diamonds can be dissected as a half-model on a symmetry plane into a space-filling heptahedron with 6 vertices, 11 edges, and 7 faces (6 triangles and 1 trapezoid). Michael Goldberg identifies this polyhedron as a triply truncated quadrilateral prism, type 7-XXIV, the 24th in a list of heptagonal space-fillers.
It can be further dissected as a quarter-model by another symmetry plane into a space-filling hexahedron with 6 vertices, 10 edges, and 6 faces (4 triangles, 2 right trapezoids). Michael Goldberg identifies this polyhedron as an ungulated quadrilateral pyramid, type 6-X, the 10th in a list of space-filling hexahedron.
Rhombic bowtie
Pairs of ten-of-diamonds can be attached as a nonconvex bow-tie space-filler, called a rhombic bowtie for its cross-sectional appearance. The two |

https://en.wikipedia.org/wiki/Total%20algebra | In abstract algebra, the total algebra of a monoid is a generalization of the monoid ring that allows for infinite sums of elements of a ring. Suppose that S is a monoid with the property that, for all , there exist only finitely many ordered pairs for which .
Let R be a ring. Then the total algebra of S over R is the set of all functions with the addition law given by the (pointwise) operation:
and with the multiplication law given by:
The sum on the right-hand side has finite support, and so is well-defined in R.
These operations turn into a ring. There is an embedding of R into , given by the constant functions, which turns into an R-algebra.
An example is the ring of formal power series, where the monoid S is the natural numbers. The product is then the Cauchy product.
