https://en.wikipedia.org/wiki/T-function | In cryptography, a T-function is a bijective mapping that updates every bit of the state in a way that can be described as , or in simple words an update function in which each bit of the state is updated by a linear combination of the same bit and a function of a subset of its less significant bits. If every single less significant bit is included in the update of every bit in the state, such a T-function is called triangular. Thanks to their bijectivity (no collisions, therefore no entropy loss) regardless of the used Boolean functions and regardless of the selection of inputs (as long as they all come from one side of the output bit), T-functions are now widely used in cryptography to construct block ciphers, stream ciphers, PRNGs and hash functions. T-functions were first proposed in 2002 by A. Klimov and A. Shamir in their paper "A New Class of Invertible Mappings". Ciphers such as TSC-1, TSC-3, TSC-4, ABC, Mir-1 and VEST are built with different types of T-functions.
Because arithmetic operations such as addition, subtraction and multiplication are also T-functions (triangular T-functions), software-efficient word-based T-functions can be constructed by combining bitwise logic with arithmetic operations. Another important property of T-functions based on arithmetic operations is predictability of their period, which is highly attractive to cryptographers. Although triangular T-functions are naturally vulnerable to guess-and-determine attacks, well chosen bitwise transp |

https://en.wikipedia.org/wiki/Key%20wrap | In cryptography, key wrap constructions are a class of symmetric encryption algorithms designed to encapsulate (encrypt) cryptographic key material. The Key Wrap algorithms are intended for applications such as protecting keys while in untrusted storage or transmitting keys over untrusted communications networks. The constructions are typically built from standard primitives such as block ciphers and cryptographic hash functions.
Key Wrap may be considered as a form of key encapsulation algorithm, although it should not be confused with the more commonly known asymmetric (public-key) key encapsulation algorithms (e.g., PSEC-KEM). Key Wrap algorithms can be used in a similar application: to securely transport a session key by encrypting it under a long-term encryption key.
Background
In the late 1990s, the National Institute of Standards and Technology (NIST) posed the "Key Wrap" problem: to develop secure and efficient cipher-based key encryption algorithms. The resulting algorithms would be formally evaluated by NIST, and eventually approved for use in NIST-certified cryptographic modules. NIST did not precisely define the security goals of the resulting algorithm, and left further refinement to the algorithm developers. Based on the resulting algorithms, the design requirements appear to be (1) confidentiality, (2) integrity protection (authentication), (3) efficiency, (4) use of standard (approved) underlying primitives such as the Advanced Encryption Standard (AE |

https://en.wikipedia.org/wiki/Gravitational%20biology | Gravitational biology is the study of the effects gravity has on living organisms. Throughout the history of the Earth life has evolved to survive changing conditions, such as changes in the climate and habitat. However, one constant factor in evolution since life first began on Earth is the force of gravity. As a consequence, all biological processes are accustomed to the ever-present force of gravity and even small variations in this force can have significant impact on the health and function and the system of organisms.
Gravity and life on Earth
The force of gravity on the surface of the Earth, normally denoted g, has remained constant in both direction and magnitude since the formation of the planet. As a result, both plant and animal life have evolved to rely upon and cope with it in various ways. For example, humans employ internal models in motor planning that account for the effects of gravity on gross and fine motor skills.
Plant use of gravity
Plant tropisms are directional movements of a plant with respect to a directional stimulus. One such tropism is gravitropism, or the growth or movement of a plant with respect to gravity. Plant roots grow towards the pull of gravity and away from sunlight, and shoots and stems grow against the pull of gravity and towards sunlight.
Animal struggles with gravity
Gravity has had an effect on the development of animal life since the first single-celled organism.

https://en.wikipedia.org/wiki/Entropic%20security | Entropic security is a security definition used in the field of cryptography. Modern encryption schemes are generally required to protect communications even when the attacker has substantial information about the messages being encrypted. For example, even if an attacker knows that an intercepted ciphertext encrypts either the message "Attack" or the message "Retreat", a semantically secure encryption scheme will prevent the attacker from learning which of the two messages is encrypted. However, definitions such as semantic security are too strong to achieve with certain specialized encryption schemes. Entropic security is a weaker definition that can be used in the special case where an attacker has very little information about the messages being encrypted.
It is well known that certain types of encryption algorithm cannot satisfy definitions such as semantic security: for example, deterministic encryption algorithms can never be semantically secure. Entropic security definitions relax these definitions to cases where the message space has substantial entropy (from an adversary's point of view). Under this definition it is possible to prove security of deterministic encryption.
Note that in practice entropically-secure encryption algorithms are only "secure" provided that the message distribution possesses high entropy from any reasonable adversary's perspective. This is an unrealistic assumption for a general encryption scheme, since one cannot assume that all li |

https://en.wikipedia.org/wiki/Pairing-based%20cryptography | Pairing-based cryptography is the use of a pairing between elements of two cryptographic groups to a third group with a mapping to construct or analyze cryptographic systems.
Definition
The following definition is commonly used in most academic papers.
Let be a Finite field over prime , two additive cyclic groups of prime order and another cyclic group of order written multiplicatively. A pairing is a map: , which satisfies the following properties:
Bilinearity
Non-degeneracy
Computability There exists an efficient algorithm to compute .
Classification
If the same group is used for the first two groups (i.e. ), the pairing is called symmetric and is a mapping from two elements of one group to an element from a second group.
Some researchers classify pairing instantiations into three (or more) basic types:
;
but there is an efficiently computable homomorphism ;
and there are no efficiently computable homomorphisms between and .
Usage in cryptography
If symmetric, pairings can be used to reduce a hard problem in one group to a different, usually easier problem in another group.
For example, in groups equipped with a bilinear mapping such as the Weil pairing or Tate pairing, generalizations of the computational Diffie–Hellman problem are believed to be infeasible while the simpler decisional Diffie–Hellman problem can be easily solved using the pairing function. The first group is sometimes referred to as a Gap Group because of the assumed difference in |
https://en.wikipedia.org/wiki/Giovanni%20Frattini | Giovanni Frattini (8 January 1852 – 21 July 1925) was an Italian mathematician, noted for his contributions to group theory.
Biography
Frattini entered the University of Rome in 1869, where he studied mathematics with Giuseppe Battaglini, Eugenio Beltrami, and Luigi Cremona, obtaining his Laurea in 1875.
In 1885 he published a paper where he defined a certain subgroup of a finite group. This subgroup, now known as the Frattini subgroup, is the subgroup generated by all the non-generators of the group . He showed that is nilpotent and, in so doing, developed a method of proof known today as Frattini's argument.
Besides group theory, he also studied
differential geometry and the analysis of second degree indeterminates.

It is affiliated with the Romanian Academy, and it is named after Simion Stoilow, one of its founders.
History
On December 29, 1945, a group of twenty Romanian mathematicians from various institutions in Bucharest led by Dimitrie Pompeiu held a meeting at the University of Bucharest to establish the Institute of Mathematical Sciences with the aim of "promoting scientific research in mathematical sciences, through communications, talks, publications, congresses, and other means proper to this aim". This group also included Dan Barbilian, Alexandru Froda, Alexandru Ghica, Gheorghe Mihoc, Grigore Moisil, Miron Nicolescu, Octav Onicescu, Stoilow, Gabriel Sudan, Victor Vâlcovici, and Gheorghe Vrănceanu. In January 1946 they registered the Institute as a legal person, specifically an NGO, with the Ilfov County Court.
On June 9, 1948 the new Communist regime revamped the Romanian Academy to an institution modeled on the Academy of Sciences of the USSR, increasing by 1966 the number of its member research centers and institutes from 7 to 56. Among the newly created institutes was the Institute of Mathematics of the Romanian Academy, established in 1949 on the basis of the previous NGO with the contribution of Simion Stoilow, one of the twenty founding members from 1945.

https://en.wikipedia.org/wiki/Charlotte%20Scott | Charlotte Angas Scott (8 June 1858 – 10 November 1931) was a British mathematician who made her career in the United States and was influential in the development of American mathematics, including the mathematical education of women. Scott played an important role in Cambridge changing the rules for its famous Mathematical Tripos exam.
Early life
She was the second of seven children to Caleb Scott, a minister of the Congregational Church, and Eliza Exley Scott. Educated at Girton College, Cambridge from 1876 to 1880 on a scholarship, she was then a Resident Lecturer in Mathematics there until 1884. In 1885 she became one of the first British women to receive a doctorate, and the first British woman to receive a doctorate in mathematics, which she received from the University of London. She did her graduate research under Arthur Cayley at Cambridge University, but since Cambridge did not begin issuing degrees to women until 1948, Scott received her BSc (1882) and D.Sc. (1885) from the University of London through external examinations.
Passing the Tripos
In 1880, Scott obtained special permission to take the Cambridge Mathematical Tripos Exam, as women were not normally allowed to sit for the exam. She came eighth on the Tripos of all students taking them, but due to her sex, the title of "eighth wrangler," a high honour, went officially to a male student.
At the ceremony, however, after the seventh wrangler had been announced, all the students in the audience shouted her |
https://en.wikipedia.org/wiki/Relative%20interior | In mathematics, the relative interior of a set is a refinement of the concept of the interior, which is often more useful when dealing with low-dimensional sets placed in higher-dimensional spaces.
Formally, the relative interior of a set (denoted ) is defined as its interior within the affine hull of In other words,

A set is relatively open iff it is equal to its relative interior. Note that when is a closed subspace of the full vector space (always the case when the full vector space is finite dimensional) then being relatively closed is equivalent to being closed.
For any convex set the relative interior is equivalently defined as
where means that there exists some such that .
Comparison to interior
The interior of a point in an at least one-dimensional ambient space is empty, but its relative interior is the point itself.
The interior of a line segment in an at least two-dimensional ambient space is empty, but its relative interior is the line segment without its endpoints.
The interior of a disc in an at least three-dimensional ambient space is empty, but its relative interior is the same disc without its circular edge.

https://en.wikipedia.org/wiki/James%20Kaiser | James Frederick Kaiser (Dec. 10, 1929 – Feb. 13, 2020) was an American electrical engineer noted for his contributions in signal processing. He was an IEEE Fellow and received many honors and awards, including the IEEE Centennial Medal, the IEEE W.R.G. Baker Award, the Bell Laboratories Distinguished Technical Staff Award, and the IEEE Jack S. Kilby Signal Processing Medal.
Biography
Kaiser was born in Piqua, Ohio, and earned his electrical engineering degree from the University of Cincinnati in 1952. He then moved to the Massachusetts Institute of Technology and received his masters and doctorate degrees in 1954 and 1959, respectively.
Following his doctorate, he received a three-year appointment as an assistant professor at MIT but decided to take a leave of absence to work at Bell Labs. Although the arrangement was due to only last for a year, he enjoyed the work so much that he elected to stay. While at Bell Labs, he worked on a variety of projects in signal processing for human speech and hearing, later focusing his attention on filter design for digital signals.
During the Bell System breakup in 1984, Kaiser moved to Bellcore. After he retired from Bellcore, he served as a visiting professor at Duke University and Rutgers University.

https://en.wikipedia.org/wiki/Link%20time | In computer science, link time refers to the period of time, during the creation of a computer program, in which a linker is being applied to that program. Link time occurs after compile time and before runtime (when a program is executed).
It is common to speak of link time operations (the operations performed by a linker) or link time requirements (programming language requirements that must be met by compiled source code for it to be successfully linked).
Link time operations
The operations performed at link time usually include fixing up the addresses of externally referenced objects and functions, various kinds of cross module checks (e.g. type checks on externally visible identifiers and in some languages instantiation of templates). Some optimizing compilers delay code generation until link time because it is here that information about a complete program is available to them. Resolving external variables in a program is also done at link time.
The link-time optimization (LTO), when enabled, occurs at link time.
Link time requirements
The definition of a programming language may specify link time requirements that source code must meet to be successfully compiled (e.g. the maximum number of characters in an externally visible identifier that must be considered significant).
Exceptions
In some programming languages it may be necessary for some compilation and linking to occur at runtime.

https://en.wikipedia.org/wiki/Low%20voltage | In electrical engineering, low voltage is a relative term, the definition varying by context. Different definitions are used in electric power transmission and distribution, compared with electronics design. Electrical safety codes define "low voltage" circuits that are exempt from the protection required at higher voltages. These definitions vary by country and specific codes or regulations.
IEC Definition
May depend on the applicable standard used.
The International Electrotechnical Commission (IEC) Standard IEC 61140:2016 defines Low voltage as 0 to 1000 V AC RMS or 0 to 1500 V DC Other standards such as IEC 60038 defines supply system low voltage as voltage in the range 50 to 1000 V AC or 120 to 1500 V DC in IEC Standard Voltages which defines power distribution system voltages around the world.
In electrical power systems low voltage most commonly refers to the mains voltages as used by domestic and light industrial and commercial consumers. "Low voltage" in this context still presents a risk of electric shock, but only a minor risk of electric arcs through the air.
United Kingdom
British Standard BS 7671, Requirements for Electrical Installations. IET Wiring Regulations, defines supply system low voltage as:
exceeding 50 V ac or 120 V ripple-free dc.
but not exceeding 1000 V ac or 1500 V dc between conductors, or 600 V ac or 900 V dc between conductors and earth.
The ripple-free direct current requirement only applies to 120 V dc, not to any dc voltage above th |

Life
Born in Fayence, France, Dulac graduated from École Polytechnique (Paris, class of 1892) and obtained a Doctorate in Mathematics. He started to teach a class of mathematic analysis at University, in Grenoble (France), Algiers (today Algeria) and Poitiers (France). Holder of a pulpit in pure mathematics in the Sciences University of Lyon (France) in 1911, his teaching was suspended during the first world war (1914 – 1918) and he had to serve as officer in the French army. After the war, he became holder of a pulpit of differential and integral calculus and also taught in École Centrale Lyon. He became examiner at École Polytechnique (Paris) and President of the admission jury. Awarded Officer of Legion d'honneur, the French order established by Napoleon and associate member of the French Academy of Sciences, he published part of Euler's works and contributed to the research through many publications in France and abroad.
Father of 3 children, Anie (1901 – 1935), bachelor in mathematics, Jean (1903 – 2005), graduate of École Polytechnique, 1921 and Robert (1904 - 1996), graduate of polytechnique, 1922; he died in Fayence, France, in 1955.

He is known as the "father of sesame" in the Western Hemisphere for his basic research on the genetics of sesame. Most of the sesame lines grown in the Americas came from his breeding work. Sesame plants are a rich source of vitamins and minerals, and Langham focused on cross-breeding the plant into more fruitful versions. He also attempted to look for other uses of sesame beyond a mere food source.
Derald Langham is less known for his genetic work in corn and beans. The Rockefeller Institute in Mexico incorporated his varieties into their materials and his genes are carried on in almost every corn hybrid used in the world.
Family and education
He was born on a farm in Polk City, Iowa, where his interest in plants and animals was piqued at an early age.
Langham attended Iowa State College and studied agronomy, where he met the head of the genetics department, Dr. Ernest W. Lindstrom. Lindstrom encouraged him to pursue his interest in genetics, and he continued his studies under Professor Rollins A. Emerson at Cornell University.
Langham received his first Ph.D. in genetics in from Cornell University in Plant Genetics in 1939, and his second Ph.D. in humanities in 1969 from United States International University in San Diego.

Early life
Paco Nathan was brought up in San Luis Obispo, California. He studied mathematics and computer science at Stanford University, specializing in user interface design and artificial intelligence, with Douglas Lenat as graduate advisor.
He received a teaching fellowship during 1984–1986, under the direction of Stuart Reges, to create a course called CS1E, as a peer-teaching introduction to using the Internet, informally called "PCs for Poets". It has since grown to become the popular Residential Computing program on campus.
Career
Nathan collaborated with Robby Garner and the Italian researcher Luigi Caputo, President of Alma Research Centre, on one of the first web chatterbots, named Barry DeFacto, in 1995.
The three have worked together on several related projects, including the JFRED open source project for developing Java-based chat bots. They used JFRED in BBC Television's "Tomorrow's World MegaLab Experiment" and attained a 17% Turing percentage during what was the largest online Turing test at the time.

https://en.wikipedia.org/wiki/Roger%20Hawken | Roger William Hercules Hawken (12 May 1878 – 18 October 1947), an Australian engineer, was the first lecturer in civil engineering, and then a professor, at the University of Queensland.
Personal life
Hawken was born at Darlington, New South Wales, the son of Nicholas Hawken MLC and Mary Jane (née Vance). He attended Newington College (1893–1896) and in 1895 won the Wigram Allen Scholarship, awarded by Sir George Wigram Allen, for mathematics. His tertiary education was at the University of Sydney (B.C.E., 1900; B.A., 1902). He also received a Masters of Engineering from the University of Sydney.
He died on 18 October 1947 after a week's illness and was cremated at Mt Thompson Crematorium. He was survived by his wife and five daughters.
Professional life
Hawken's academic bent was evident by 1903 in a remarkably advanced paper to the Sydney University Engineering Society on the structural analysis of bridges.
Hawken worked as an engineer in the Federated Malay States for four years and then with local government authorities in New South Wales. In 1912 Hawken was appointed as a lecturer at the University of Queensland.
He graduated M.C.E. from Sydney in 1918 after submitting a thesis on column design, a frontier topic of the period, and appears to have had slightly the better of a lively argument with the eminent English engineer, E. H. Salmon, who had written an authoritative text on the subject.
Hawken was appointed as professor at the University of Queensland in 1919. |
https://en.wikipedia.org/wiki/Lynn%20Steen | Lynn Arthur Steen (January 1, 1941 – June 21, 2015) was an American mathematician who was a professor of mathematics at St. Olaf College, Northfield, Minnesota, in the U.S. He wrote numerous books and articles on the teaching of mathematics. He was a past president of the Mathematics Association of America (MAA) and served as chairman of the Conference Board of the Mathematical Sciences.
Biography
Steen was born in Chicago, Illinois, but was raised in Staten Island, New York. His mother was a singer at the N.Y. City Center Opera and his father conducted the Wagner College Choir. In 1961, Steen graduated from Luther College with a degree in mathematics and a minor in physics. In 1965 Steen graduated from MIT with a Ph.D. in mathematics. He then joined the faculty of St. Olaf College.
At the beginning of Steen's career, he mainly focused on teaching and helping develop research experiences for undergraduates. His teaching led Steen to begin to investigate the links between mathematics and other fields. He wrote many articles aimed for a non-mathematical audience about new developments in mathematics. The majority of his work in the 1970s was regarding mathematical exposition, communicating mathematical research to students, teachers, and the public.
In the 1980s, Steen helped lead national efforts to modernize the teaching of calculus and other areas in undergraduate mathematics. He helped broaden the mathematics major at St. Olaf by focusing the students work on inquiry a |
https://en.wikipedia.org/wiki/Computational%20logic | Computational logic is the use of logic to perform or reason about computation. It bears a similar relationship to computer science and engineering as mathematical logic bears to mathematics and as philosophical logic bears to philosophy. It is synonymous with "logic in computer science".
The term “computational logic” came to prominence with the founding of the ACM Transactions on Computational Logic in 2000. However, the term was introduced much earlier, by J.A. Robinson in 1970. The expression is used in the second paragraph with a footnote claiming that "computational logic" is "surely a better phrase than 'theorem proving', for the branch of artificial intelligence which deals with how to make machines do deduction efficiently".
In 1972 the Metamathematics Unit at the University of Edinburgh was renamed “The Department of Computational Logic” in the School of Artificial Intelligence. The term was then used by Robert S. Boyer and J Strother Moore, who worked in the Department in the early 1970s, to describe their work on program verification and automated reasoning. They also founded Computational Logic Inc.
Computational logic has also come to be associated with logic programming, because much of the early work in logic programming in the early 1970s also took place in the Department of Computational Logic in Edinburgh. It was reused in the early 1990s to describe work on extensions of logic programming in the EU Basic Research Project "Compulog" and in the associate |
https://en.wikipedia.org/wiki/BassOmatic | In cryptography, BassOmatic is the symmetric-key cipher designed by Phil Zimmermann as part of his email encryption software PGP (in the first release, version 1.0). Comments in the source code indicate that he had been designing the cipher since as early as 1988, but it was not publicly released until 1991. After Eli Biham pointed out to him several serious weaknesses in the BassOmatic algorithm over lunch at the 1991 CRYPTO conference, Zimmermann replaced it with IDEA in subsequent versions of PGP.
The name is explained in this comment from the source code: "BassOmatic gets its name from an old Dan Aykroyd Saturday Night Live skit involving a blender and a whole fish. The BassOmatic algorithm does to data what the original BassOmatic did to the fish."
Algorithm
The algorithm operates on blocks of 256 bytes (or 2048 bits). The actual key size can be anywhere from 8 to 2048 bits. The 6 least-significant bits of the key are control bits, used to choose between several possible variations. The number of rounds is 1 to 8, depending on the 3 lowest control bits. Bit 4 selects between two possible key schedules: one using the key to seed a pseudorandom number generator, the other using BassOmatic itself. Making such variations key-dependent means that some keys must be weaker than others; the key space is not flat.
The chosen key schedule produces a total of 8 permutation tables, each a permutation of the numbers 0 to 255. Each round consists of 4 operations: XORing the block w |
https://en.wikipedia.org/wiki/Leray%E2%80%93Hirsch%20theorem | In mathematics, the Leray–Hirsch theorem is a basic result on the algebraic topology of fiber bundles. It is named after Jean Leray and Guy Hirsch, who independently proved it in the late 1940s. It can be thought of as a mild generalization of the Künneth formula, which computes the cohomology of a product space as a tensor product of the cohomologies of the direct factors. It is a very special case of the Leray spectral sequence.

https://en.wikipedia.org/wiki/Hajime%20Tanabe | was a Japanese philosopher of science, particularly of mathematics and physics. His work brought together elements of Buddhism, scientific thought, Western philosophy, Christianity, and Marxism. In the postwar years, Tanabe coined the concept of metanoetics, proposing that the limits of speculative philosophy and reason must be surpassed by metanoia.
Tanabe was a key member of what has become known in the West as the Kyoto School, alongside philosophers Kitaro Nishida (also Tanabe's teacher) and Keiji Nishitani. He taught at Tōhoku Imperial University beginning in 1913 and later at Kyōto Imperial University, and studied at the universities of Berlin, Leipzig, and Freiburg in the 1920s under figures such as Edmund Husserl and Martin Heidegger. In 1947 he became a member of the Japan Academy, and in 1950 he received the Order of Cultural Merit.
Biography
Tanabe was born on February 3, 1885, in Tokyo to a household devoted to education. His father, the principal of Kaisei Academy, was a scholar of Confucius, whose teachings may have influenced Tanabe's philosophical and religious thought. Tanabe enrolled at Tokyo Imperial University, first as a mathematics student before moving to literature and philosophy. After graduation, he worked as a lecturer at Tohoku University and taught English at Kaisei Academy.
In 1916, Tanabe translated Henri Poincaré’s La Valeur de la science. In 1918, he received his doctorate from Kyoto Imperial University with a dissertation entitled ‘Invest |

Herbert studied engineering physics at The Ohio State University, graduating in 1959. He received a Ph.D. in physics from Stanford University in 1967 for work on nuclear scattering experiments. After a one-year teaching job at Monmouth College in Illinois, Herbert held a number of posts in industry. The most illustrious of these was senior physicist at Memorex Corporation in Santa Clara, California, where he developed new magnetic materials, as well as magnetic, electrostatic and optical measuring devices, and carried out theoretical work on Lorentz microscopy. He was also senior physicist at Smith-Corona Marchant Corporation in Palo Alto, California where he developed a new theory of xerographic process and worked on early developments in ink jet printing.
While employed in industry, Herbert was part of the Fundamental Fysiks Group at Lawrence Berkeley National Laboratory, founded in May 1975 by Elizabeth Rauscher and George Weissmann. The group's initial interest was in the interpretation of quantum mechanics, the EPR paradox, and Bell's inequality, and members pursued also diverse interests that lay outside of mainstream physics, exploring psychedelic drugs, psi phenomena, the nature of consciousness, and speculative connections of these areas with quantum physics.

https://en.wikipedia.org/wiki/Michael%20Kudish | Michael Kudish is an author, railroad historian, forest historian, botanist, and retired emeritus professor. He received his Ph.D. in botany in 1971 from the State University of New York College of Environmental Science and Forestry at Syracuse. His dissertation, on the history of Catskill forests, was the beginning of a lifelong study. It was later expanded and published in book form as The Catskill Forest: A History. His previous degrees included a B.S. from the City College of New York, and an M.S. from Cornell University (1968).
As a professor in the Division of Forestry at Paul Smith's College, he has written three books on the flora of the Adirondacks, including Adirondack Upland Flora, as well as a vast number of articles on forest history of both the Catskills and Adirondacks. As a railroad historian, he wrote Where Did The Tracks Go?, an initial description of railroads in the Adirondacks, followed by Railroads of the Adirondacks, for a long time considered the definitive work on the subject. He has since retired from Paul Smith's College, moved to the Catskills, and has completed a four-volume set on the Mountain Railroads of New York State. It updates Railroads of the Adirondacks in the first three volumes, and adds a fourth volume covering the Catskills (with a separate Addendum volume of 55 pages).
The Michael Kudish Natural History Preserve in Stamford, New York is named for him.

https://en.wikipedia.org/wiki/Weakly%20contractible | In mathematics, a topological space is said to be weakly contractible if all of its homotopy groups are trivial.
Property
It follows from Whitehead's Theorem that if a CW-complex is weakly contractible then it is contractible.
Example
Define to be the inductive limit of the spheres . Then this space is weakly contractible. Since is moreover a CW-complex, it is also contractible. See Contractibility of unit sphere in Hilbert space for more.
The Long Line is an example of a space which is weakly contractible, but not contractible. This does not contradict Whitehead theorem since the Long Line does not have the homotopy type of a CW-complex.
Another prominent example for this phenomenon is the Warsaw circle.

https://en.wikipedia.org/wiki/Ackermann%20set%20theory | In mathematics and logic, Ackermann set theory (AST) is an axiomatic set theory proposed by Wilhelm Ackermann in 1956.
AST differs from Zermelo–Fraenkel set theory (ZF) in that it allows proper classes, that is, objects that are not sets, including a class of all sets.
It replaces several of the standard ZF axioms for constructing new sets with a principle known as Ackermann's schema. Intuitively, the schema allows a new set to be constructed if it can be defined by a formula which does not refer to the class of all sets.
In its use of classes, AST differs from other alternative set theories such as Morse–Kelley set theory and Von Neumann–Bernays–Gödel set theory in that a class may be an element of another class.
William N. Reinhardt established in 1970 that AST is effectively equivalent in strength to ZF, putting it on equal foundations. In particular, AST is consistent if and only if ZF is consistent.
Preliminaries
AST is formulated in first-order logic. The language of AST contains one binary relation denoting set membership and one constant denoting the class of all sets. Ackermann used a predicate instead of ; this is equivalent as each of and can be defined in terms of the other.
We will refer to elements of as sets, and general objects as classes. A class that is not a set is called a proper class.
Axioms
The following formulation is due to Reinhardt.
The five axioms include two axiom schemas.

Biography
J. P. Den Hartog was born in 1901 in Ambarova, the Dutch East Indies. In 1916 his family moved to Holland. After attending high school in Amsterdam, he enrolled at Delft University of Technology in 1919 and received his MSc degree in electrical engineering in 1924. Unable to find suitable work in the Netherlands, he emigrated to the United States in 1924.
From 1924 to 1930 he worked as an electrical engineer in the research laboratory of Westinghouse Electric (1886) in Pittsburgh. There under the influence of Stephen P. Timoshenko, who took him as his assistant, he began to study electrical and mechanical vibrations. At the same time, he attended night classes in Mathematics at the University of Pittsburgh, where he became an authority in problems on mechanics and vibration and received a doctorate in 1939.
In 1930-1931 he studied at the University of Göttingen where he collaborated in the laboratory of Ludwig Prandtl (whose fellow Oscar Carl Gustav Titens previously worked for Westinghouse). From 1932 to 1945 he taught at Harvard University and took part in the organization of the International Congress of Applied Mechanics in Cambridge (Massachusetts) 1938.
During the Second World War, he volunteered to serve in the US Navy, was engaged in the problems of vibration in shipbuilding.

https://en.wikipedia.org/wiki/SOBER | In cryptography, SOBER is a family of stream ciphers initially designed by Greg Rose of QUALCOMM Australia starting in 1997. The name is a contrived acronym for Seventeen Octet Byte Enabled Register. Initially the cipher was intended as a replacement for broken ciphers in cellular telephony. The ciphers evolved, and other developers (primarily Phillip Hawkes) joined the project.
SOBER was the first cipher, with a 17-byte linear-feedback shift register (LFSR), a form of decimation called stuttering, and a nonlinear output filter function. The particular configuration of the shift register turned out to be vulnerable to "guess and determine" attacks.
SOBER-2 changed the position of the feedback and output taps to resist the above attacks.
S16 was an expansion to 16-bit words rather than bytes, with an expected increase of security.
Adaptions for and since NESSIE
For the NESSIE call for new cryptographic primitives, three new versions called the t-class were developed; SOBER-t8 was virtually identical to SOBER-2 but did not have sufficient design strength for NESSIE submission; SOBER-t16 and SOBER-t32 were submitted. t32 was a further expansion to 32-bit words, while both ciphers had a more efficient method of computing the linear feedback.
Subsequent to NESSIE, SOBER-128 was designed to take into account what had been learned. The stuttering was dropped because it added too little strength for the overhead, and the nonlinear output function was strengthened. As a stream c |

https://en.wikipedia.org/wiki/Convex%20body | In mathematics, a convex body in -dimensional Euclidean space is a compact convex set with non-empty interior.
A convex body is called symmetric if it is centrally symmetric with respect to the origin; that is to say, a point lies in if and only if its antipode, also lies in Symmetric convex bodies are in a one-to-one correspondence with the unit balls of norms on
Important examples of convex bodies are the Euclidean ball, the hypercube and the cross-polytope.
Kinds of convex bodies
A convex body may be defined as:
A Convex set of points.
The Convex Hull of a set of points.
The intersection of Hyperplanes.
The interior of any Convex polygon or Convex polytope.
Polar body
If is a bounded convex body containing the origin in its interior, the polar body is . The polar body has several nice properties including , is bounded, and if then . The polar body is a type of duality relation.

https://en.wikipedia.org/wiki/Reciprocity%20%28evolution%29 | Reciprocity in evolutionary biology refers to mechanisms whereby the evolution of cooperative or altruistic behaviour may be favoured by the probability of future mutual interactions. A corollary is how a desire for revenge can harm the collective and therefore be naturally deselected.
Main types
Three types of reciprocity have been studied extensively:
Direct reciprocity
Indirect
Network reciprocity
Direct reciprocity
Direct reciprocity was proposed by Robert Trivers as a mechanism for the evolution of cooperation. If there are repeated encounters between the same two players in an evolutionary game in which each of them can choose either to "cooperate" or "defect", then a strategy of mutual cooperation may be favoured even if it pays each player, in the short term, to defect when the other cooperates. Direct reciprocity can lead to the
evolution of cooperation only if the probability, w, of another encounter between the same two individuals exceeds the cost-to-benefit ratio of the altruistic act: w > c / b
Indirect reciprocity
"In the standard framework of indirect reciprocity, there are randomly chosen pairwise encounters between members of a population; the same two individuals need not meet again. One individual acts as donor, the other as recipient. The donor can decide whether or not to cooperate. The interaction is observed by a subset of the population who might inform others. Reputation allows evolution of cooperation by indirect reciprocity. Natural selecti |

Education
He received the B.S.(magna cum laude) and M.S. degrees (major in mathematics) from North Carolina Central University (NCCU), Durham, NC in 1956 and 1958 respectively. He received the Ph.D. degree in mathematics from the University of Idaho in 1966.
Early career
In 1957 Dr. Fletcher accepted his first teaching position in the department of mathematics at LeMoyne-Owen College, Memphis, Tennessee, where he served as chairman until 1972. For the ten-year period 1962–72 Fletcher pursued summer employment as a mathematical applications computer programmer in industry, business, and government at IBM Mohansic Laboratory (Yorktown Heights, NY), Western Electric (Hopewell, NJ), the Lawrence Livermore Laboratory (Livermore, CA), and the US Departments of Commerce (Washington, DC), Agriculture (St. Paul, Minn), and Energy (Livermore, CA).
NCCU
In 1972 Fletcher returned to NCCU as professor and chairman of the mathematics department where he joined his former teacher and mentor, Marjorie Lee Browne, the second African-American woman to earn a Ph.D. in Mathematics. During his 25-year tenure at NCCU, Fletcher instituted a BS degree in computer science; wrote petition to obtain a chapter of Pi Mu Epsilon, honorary national mathematics society promoting scholarly activity in mathematics, organized the Marjorie Lee Browne Distinguished Alumni Lectures Series; developed, with two other alumni the Marjorie Lee Browne Memorial S |
https://en.wikipedia.org/wiki/American%20Association%20of%20Physics%20Teachers | The American Association of Physics Teachers (AAPT) was founded in 1930 for the purpose of "dissemination of knowledge of physics, particularly by way of teaching." There are more than 10,000 members in over 30 countries. AAPT publications include two peer-reviewed journals, the American Journal of Physics and The Physics Teacher. The association has two annual National Meetings (winter and summer) and has regional sections with their own meetings and organization. The association also offers grants and awards for physics educators, including the Richtmyer Memorial Award and programs and contests for physics educators and students. It is headquartered at the American Center for Physics in College Park, Maryland.
History
The American Association of Physics Teachers was founded on December 31, 1930, when forty-five physicists held a meeting during the joint APS-AAAS meeting in Cleveland specifically for that purpose.
The AAPT became a founding member of the American Institute of Physics after the other founding members were convinced of the stability of the AAPT itself after a new constitution for the AAPT was agreed upon.
Contests
The AAPT sponsors a number of competitions. The Physics Bowl, Six Flags' roller coaster contest, and the US Physics Team are just a few. The US physics team is determined by two preliminary exams and a week and a half long "boot camp." Each year, five members are selected to compete against dozens of countries in the International Physics Olympiad |

https://en.wikipedia.org/wiki/Big%20Dig%20%28Liverpool%29 | The Big Dig was a collection of various civil engineering projects in Liverpool to regenerate the city.
The scheme was a ten-year plan for the city's 2008 European Capital of Culture status. The city gained a new shopping centre Liverpool One. It cost around £3bn and created 14,000 jobs and included a rationalisation of the city centre traffic network.
Criticism
Implementation of the scheme was protracted and severely hampered the ability of the city to perform as a commercial centre. The cancellation of the 2007 Mathew Street Festival was directly attributed to the 'big dig'.

Dahlquist began to study mathematics at Stockholm University in 1942 at the age of 17, where he cites the Danish mathematician Harald Bohr (who was living in exile after the occupation of Denmark during World War II) as a profound influence.
He received the degree of licentiat from Stockholm University in 1949, before taking a break from his studies to work at the Swedish Board of Computer Machinery (Matematikmaskinnämnden), working on (among other things) the early computer BESK, Sweden's first. During this time, he also worked with Carl-Gustaf Rossby on early numerical weather forecasts.
Dahlquist returned to Stockholm University to complete his Ph.D., Stability and Error Bounds in the Numerical Solution of Ordinary Differential Equations, which he defended in 1958, with Fritz Carlson and Lars Hörmander as his advisors. As part of this work he introduced the logarithmic norm (also introduced by Russian mathematician Sergei Lozinskii the same year).
In 1959 he moved to the Royal Institute of Technology (KTH), where he would later establish what became the Department of Numerical Analysis and Computer Science (NADA) in 1962 (now part of the School of Computer Science and Communication), and become Sweden's first Professor of Numerical Analysis in 1963.

https://en.wikipedia.org/wiki/Cardkey | Cardkey was a producer of electronic access control products and was based in Simi Valley, California. They were the first company to develop and widely distribute "Electronic Access Control Systems".
The company's original readers used cards which were made from barium ferrite and worked by magnetically attracting and repelling locking/unlocking cores within the reader module mechanism. These cards were primarily used by fraternal organizations and clubs, such as BPOE (Elks) and others.
From there they were the first to develop Wiegand cards and readers which were again magnetically based but were more reliable and did not require calibration as used in the barium ferrite readers. These cards and readers were highly programmable, and used in applications ranging from ADT (American District Telegraph) to government installations worldwide.
In the UK they had offices in Manchester and Reading and sold their systems to companies such as British Telecom, Shell and BP. The main facility for Cardkey was located on Nordhoff and Mason in Chatsworth with an additional location on Cozycroft in Chatsworth which housed Customer Engineering and a singular Engineering project (PASS system) in approximately 1978.
They were once a division of Greer Hydraulics, Inc., and in January 1999 they were bought out by Johnson Controls, a company whose founder invented the electric room thermostat in the late 1800s.
