Dyadic derivative
In mathematical analysis, the dyadic derivative is a concept that extends the notion of classical differentiation to functions defined on the dyadic group or the dyadic field. Unlike classical differentiation, which is based on the limit of difference quotients, dyadic differentiation is defined using dyadic (binary) addition and reflects the discontinuous nature of Walsh functions.

Mathematical analysis
Analysis is the branch of mathematics dealing with continuous functions, limits, and related theories, such as differentiation, integration, measure, infinite sequences, series, and analytic functions.

These theories are usually studied in the context of real and complex numbers and functions. Analysis evolved from calculus, which involves the elementary concepts and techniques of analysis.
Analysis may be distinguished from geometry; however, it can be applied to any space of mathematical objects that has a definition of nearness (a topological space) or specific distances between objects  (a metric space).
Killer World Tour
The Killer World Tour was a concert tour by the English heavy metal band Iron Maiden from 17 February 1981 to 15 November 1981. This was the band's first world tour, including their debut shows in North America (where they supported Judas Priest on their World Wide Blitz Tour, and UFO on select dates) and Japan where they recorded the live release, Maiden Japan. On top of this, the band moved into larger venues in the United Kingdom, including the Hammersmith Odeon, in London.

This would be Iron Maiden's last tour with singer Paul Di'Anno, who was dismissed due to his unreliability. He was replaced by Samson vocalist Bruce Dickinson, with whom the band undertook a short series of concerts in Italy and the UK from 26 October to 23 December, before they set about writing and recording their next album, The Number of the Beast.

Lakeba
Lakeba (pronounced [laˈkemba]) is an island in Fiji’s Southern Lau Archipelago; the provincial capital of Lau is located here. The island is the tenth largest in Fiji, with a land area of nearly 60 square kilometers. It is fertile and well watered, and encircled by a 29-kilometer road. Its closest neighbors are Aiwa and Nayau. Separated by deep sea from the latter but only by shallow waters from the former, when sea levels were lower during glacial episodes Lakeba and Aiwa formed one large island.

It has a population of around 2,100 in eight villages, the most important of which is the capital Tubou which lies in the island's south. Near Tubou is the village of Levuka; not to be confused with its namesake – Fiji's old capital – Levuka on Lakeba is home to a fishing tribe whose ancestors came from Bau Island. Another significant village is Nasaqalau, located in the northern part of Lakeba.

Bau (island)
Bau (pronounced [ᵐbɔu̯]) is a small island in Fiji, off the east coast of the main island of Viti Levu. Bau rose to prominence in the mid-1800s and became Fiji's dominant power; until its cession to Britain, it has maintained its influence in politics and leadership right through to modern Fiji. Due to its sacred nature, foreigners have to apply for a permit to visit.

Huprine X
Huprine X is a synthetic cholinergic compound developed as a hybrid between the natural product Huperzine A and the synthetic drug tacrine. It is one of the most potent reversible inhibitors of acetylcholinesterase known, with a binding affinity of 0.026nM, as well as showing direct agonist activity at both nicotinic and muscarinic acetylcholine receptors. In animal studies it has nootropic and neuroprotective effects, and is used in research into Alzheimer's disease, and although huprine X itself has not been researched for medical use in humans, a large family of related derivatives have been developed.

Tacrine
Tacrine is a centrally acting acetylcholinesterase inhibitor and indirect cholinergic agonist (parasympathomimetic). It was the first centrally acting cholinesterase inhibitor approved for the treatment of Alzheimer's disease, and was marketed under the trade name Cognex. Tacrine was first synthesised by Adrien Albert at the University of Sydney in 1949. It also acts as a histamine N-methyltransferase inhibitor.
HD 86226
HD 86226 is a star with a pair of orbiting exoplanet companions, found in the constellation of Hydra. With an apparent visual magnitude of 7.93, it is too dim to be visible with the naked eye. The distance to this system has been determined by the parallax method, yielding a range of 149 light years. It is receding with a heliocentric radial velocity of +19.6 km/s. A survey in 2015 has ruled out the existence of any stellar companions at projected distances above 12 astronomical units.

Hydra (constellation)
Hydra is the largest of the 88 modern constellations, measuring 1303 square degrees, and also the longest at over 100 degrees. Its southern end borders Libra and Centaurus and its northern end borders Cancer. It was included among the 48 constellations listed by the 2nd century astronomer Ptolemy. Commonly represented as a water snake, it straddles the celestial equator.
Mitchell Archaeological Site (Mitchell, Illinois)
The Mitchell Archaeological Site is a pre-Columbian archaeological site located at the western end of University Drive in Mitchell, Illinois. The site includes a platform mound and the remains of a village; while it once included several other mounds, they have been destroyed by modern activity. Mississippian peoples inhabited the site c. 1150–1200. The site is affiliated with the Cahokia settlement system and was the largest site in the system except for Cahokia itself. However, the majority of the site was destroyed by the construction of Interstate 270; known information about the site mainly comes from salvage excavations conducted before the highway was built.

The site was added to the National Register of Historic Places on February 7, 1978.

Mississippian culture
The Mississippian culture was a collection of Native American societies that flourished in what is now the Midwestern, Eastern, and Southeastern United States from approximately 800 to 1600 CE, varying regionally. It was known for building large, earthen platform mounds, and often other shaped mounds as well. It was composed of a series of urban settlements and satellite villages linked together by loose trading networks. The largest city was Cahokia, believed to be a major religious center, located in what is present-day southern Illinois.

The Mississippian way of life began to develop in the Mississippi River Valley (for which it is named). Cultures in the tributary Tennessee River Valley may have also begun to develop Mississippian characteristics at this point. Almost all dated Mississippian sites predate 1539–1540 (when Hernando de Soto explored the area), with notable exceptions being Natchez communities. These maintained Mississippian cultural practices into the 18th century.

4 Arietis
4 Arietis is a single star in the northern constellation of Aries, the ram. 4 Arietis is the Flamsteed designation. It is visible to the naked eye as a dim, blue-white hued star with an apparent visual magnitude of 5.86. The star has an annual parallax shift of 11.46±0.15 mas, which is equivalent to a distance of 285 light-years (87 parsecs) from the Sun. It is moving further from the Earth with a heliocentric radial velocity of +6 km/s.

This is a B-type main sequence star with a stellar classification of B9.5 V. It is 257 million years old and is spinning with a projected rotational velocity of 33 km/s. The star has more than double the mass of the Sun and around 2.2 times the Sun's radius. It is radiating 40 times the Sun's luminosity from its photosphere at an effective temperature of 10,913 K.

B-type main-sequence star
A B-type main-sequence star is a main-sequence (core hydrogen-burning) star of spectral type B. The spectral luminosity class is given as V. These stars have from 2 to 18 times the mass of the Sun and surface temperatures between about 10,000 and 30,000 K.

B-type stars are luminous and blue-white. Their spectra have strong neutral helium absorption lines, which are most prominent at the B2 subclass, and moderately strong hydrogen lines. Examples include Regulus, Algol A and Acrux.
Callippic cycle
The Callippic cycle (or Calippic) is a particular approximate common multiple of the tropical year, the synodic month and the day, proposed by Callippus in 330 BC. It is a period of 76 years, as an improvement of the 19-year Metonic cycle.

Attic calendar
The Attic calendar or Athenian calendar is the lunisolar calendar beginning in midsummer with the lunar month of Hekatombaion, in use in ancient Attica, the ancestral territory of the Athenian polis. It is sometimes called the Greek calendar because of Athens's cultural importance, but it is only one of many ancient Greek calendars.

Although relatively abundant, the evidence for the Attic calendar is still patchy and often contested. As it was well known in Athens and of little use outside Attica, no contemporary source set out to describe the system as a whole. Further, even during the well-sourced 5th and 4th centuries BC, the calendar underwent changes, not all perfectly understood. As such, any account given of it must be a tentative reconstruction.
Kweneng' Ruins
Kweneng’ ruins are the remains of a pre-colonial Tswana capital occupied from the 14th to the 19th century AD in South Africa. The site is located 30km south of the modern-day city of Johannesburg. Settlement at the site likely began around the 1300s and saw its peak in the 14th century. The Kweneng' ruins are similar to those built by other early civilizations found in the southern Africa region during this period, including the Luba–Lunda kingdom, Kingdom of Mutapa, Bokoni, and many others, as these groups share ancestry. Kweneng' was the largest of several sizable settlements inhabited by Tswana speakers prior to European arrival. Several circular stone walled family compounds are spread out over an area 10km long and 2km wide. It is likely that Kweneng' was abandoned in the 1820s during the period of colonial expansion-related civil wars known as the Mfecane or Difaqane, leading to the dispersal of its inhabitants.

Bokoni
Bokoni (meaning 'land of the people from the north') was a pre-colonial, agro-pastoral society found in northwestern and southern parts of present-day Mpumalanga province, South Africa. Iconic to this area are stone-walled sites, found in a variety of shapes and forms. Bokoni sites also exhibit specialized farming and long-distance trading with other groups in surrounding regions. Bokoni saw occupation in varying forms between approximately 1500 and 1820 A.D.
African theology
African theology is Christian theology from the perspective of the African cultural context. It should be distinguished from black theology, which originated from the American and South African context and is more closely aligned with liberation theology. Although there are ancient Christian traditions on the African continent, during the modern period Christianity in Africa was significantly influenced by western forms of Christianity brought about by European colonization.

African traditional religions
The beliefs and practices of African people are highly diverse, and include various ethnic religions. Generally, these traditions are oral rather than scriptural and are passed down from one generation to another through narratives, songs, myths, and festivals. They include beliefs in spirits and higher and lower gods, sometimes including a supreme being, as well as the veneration of the dead, use of magic, and traditional African medicine. Most religions can be described as animistic with various polytheistic and pantheistic aspects. The role of humanity is generally seen as one of harmonizing nature with the supernatural.
Hooray for Captain Spaulding
"Hooray for Captain Spaulding" is a song composed by Bert Kalmar and Harry Ruby, originally from the 1928 Marx Brothers Broadway musical Animal Crackers and the 1930 film version. It later became well known as the theme song for the Groucho Marx television show You Bet Your Life (1950–1961), and became Groucho's signature tune and was usually played when he was introduced on various talk shows and the like.

The modern version of the situation comedy radio show Flywheel, Shyster, and Flywheel uses this song for its opening theme.

The line "I think I'll try to make her" from the musical, included in the initial release, was cut from rereleases, being considered too risqué.

In 1951, Groucho Marx recorded the song for release by Decca Records.

Animal Crackers (musical)
Animal Crackers is a musical play with music and lyrics by Bert Kalmar and Harry Ruby and a book by George S. Kaufman and Morrie Ryskind.

1970 1000 km of Monza
The 1970 1000 km of Monza was an endurance race held at the Autodromo Nazionale Monza in Monza, Italy, on April 25, 1970. It was the fourth round of the 1970 International Championship for Makes. This was the first official 1000 km race at Monza that used only the road course; in 1956 and 1965-1969 the organizers utilized the combined road and banking courses; but the banking was abandoned because of safety issues; the 1969 1000 km race was the last race ever held on the concrete-surfaced banking. Mexican driver Pedro Rodríguez won this race in John Wyer's Gulf-sponsored Porsche 917K, he was able to hold off 3 hard-charging works Ferrari 512's after his co-driver Leo Kinnunen lost most of the lead Rodríguez had built up. Ex-Ferrari driver John Surtees returned to Ferrari after 4 years to drive a works 512.
