Lazy caterer's sequence
The lazy caterer's sequence, more formally known as the central polygonal numbers, describes the maximum number of pieces of a disk (a pancake or pizza is usually used to describe the situation) that can be made with a given number of straight cuts. For example, three cuts across a pancake will produce six pieces if the cuts all meet at a common point inside the circle, but up to seven if they do not. This problem can be formalized mathematically as one of counting the cells in an arrangement of lines; for generalizations to higher dimensions, see arrangement of hyperplanes.

The analogue of this sequence in three dimensions is the cake numbers.

Integer sequence
In mathematics, an integer sequence is a sequence (i.e., an ordered list) of integers.

An integer sequence may be specified explicitly by giving a formula for its nth term, or implicitly by giving a relationship between its terms. For example, the sequence 0, 1, 1, 2, 3, 5, 8, 13, ... (the Fibonacci sequence) is formed by starting with 0 and 1 and then adding any two consecutive terms to obtain the next one: an implicit description (sequence A000045 in the OEIS). The sequence 0, 3, 8, 15, ... is formed according to the formula  for the nth term: an explicit definition.

Alternatively, an integer sequence may be defined by a property which members of the sequence possess and other integers do not possess. For example, we can determine whether a given integer is a perfect number, (sequence A000396 in the OEIS), even though we do not have a formula for the nth perfect number.
Guanidine
Guanidine is the compound with the formula HNC(NH2)2. It is a colourless solid that dissolves in polar solvents. It is a strong base that is used in the production of plastics and explosives. It is found in urine predominantly in patients experiencing renal failure. A guanidine moiety also appears in larger organic molecules, including on the side chain of arginine.

Resonance (chemistry)
In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory. It has particular value for analyzing delocalized electrons where the bonding cannot be expressed by one single Lewis structure. The resonance hybrid is the accurate structure for a molecule or ion; it is an average of the theoretical (or hypothetical) contributing structures.

Presidency of Javier Milei
Javier Milei's tenure as the 59th president of Argentina began with his inauguration on 10 December 2023. Milei, a member of La Libertad Avanza, took office after defeating then-economy minister Sergio Massa in the 2023 general election. His administration began during deep economic turmoil as part of the ongoing Argentine monetary crisis, with annual inflation surpassing 100% in the months prior to his inauguration.

Described along right-wing populist and right-wing libertarian lines, Milei pursued deregulation policies to alleviate the national economic crisis. He eliminated several government ministries within his first months in office, achieving a budget surplus for the first time since 2011. On foreign affairs, the Milei administration distanced itself from governments such as those of Venezuela and Cuba, which it calls communist, favouring closer ties with Israel amid the Gaza war and Ukraine during the Russo–Ukrainian War.

2-Methylnaphthalene-1,4-diamine
2-Methylnaphthalene-1,4-diamine is a synthetic menadione analog with vitamin K activity.

2-Methylnaphthalene-1,4-diamine was first synthesized in 1925. In 1942 two different research groups noted the vitamin K activity of the compound. It forms a dihydrochloride salt (C11H14Cl2N2) with hydrochloric acid and one of the aforementioned research groups suggested the name vitamin K6 for the salt.

2-Methylnaphthalene-1,4-diamine and its dihydrochloride can be made from 2-methylnaphthalene or its close analogs. Dihydrochloride blackens without melting at about 300 °C.

4-Amino-3-methyl-1-naphthol or its dihydrochloride have not been used as commercial medicinal forms of vitamin K unlike phylloquinone and menadione for example.

Oral toxicity of dihydrochloride for rats is approximately the same as for 4-amino-2-methyl-1-naphthol hydrochloride.

Menadione
Menadione is a natural organic compound with the formula C6H4(CO)2C2H(CH3). It is an analog of 1,4-naphthoquinone with a methyl group in the 2-position. It is sometimes called vitamin K3. Use is allowed as a nutritional supplement in animal feed because of its vitamin K activity.

Mesopotamian barbel
The Mesopotamian barbel or leopard barbel (Luciobarbus subquincunciatus) is a species of cyprinid fish found in the Tigris-Euphrates river system and is an inhabitant of large rivers. It has been (and most likely is still) declining very rapidly for at least the last 30 years. This species has disappeared for 12 years until it was rediscovered in January 2024 after a local fisherman caught an individual, and soon after another individual was captured. While there are not enough data to identify the actual rate of population decline, it was once locally abundant but now almost absent.

Cyprinidae
Cyprinidae is a family of cyprinoid freshwater fishes commonly referred to as the carp family, which includes the carps, barbs, and barbels, among others. These cyprinids also share sister taxa with the danionins and minnows under the suborder Cyprinoidei. Cyprinidae is the largest and most diverse fish family, and the largest family of vertebrates overall, with roughly 1,780 species split into 166 valid genera.

Cyprinids range from the 12 mm (0.5 in)-long glassfishes, to the 3 m (9.8 ft) giant barb (Catlocarpio siamensis). The family name is derived from the Greek word kyprînos (κυπρῖνος 'carp').

Biloxi people
The Biloxi tribe (endonym: Tanêks(a)) are Native Americans of the Siouan language family. When first encountered by Europeans in 1699, the Biloxi inhabited an area near the coast of the Gulf of Mexico near what is now the city of Biloxi, Mississippi. They were eventually forced west into Louisiana and eastern Texas. The Biloxi language (Tanêksąyaa ade) has been extinct since the 1930s, when the last known semi-speaker, Emma Jackson, died.

Today, remaining Biloxi descendants have merged with the Tunica and other remnant peoples. Together they were federally recognized in 1981; today they are called the Tunica-Biloxi Indian Tribe and share a small reservation in Avoyelles Parish, Louisiana. Descendants of several other small tribes are enrolled with them. The two main tribes were from different language groups: the Biloxi were Siouan-speaking and the Tunica had an isolate language. Today the tribe members speak English or French.

James Owen Dorsey
James Owen Dorsey  (October 31, 1848 – February 4, 1895) was an American ethnologist, linguist, and Episcopalian missionary in the Dakota Territory, who contributed to the description of the Ponca, Omaha, and other southern Siouan languages. He worked for the Bureau of American Ethnology of the Smithsonian Institution from 1880 to 1895, when he died young of typhoid fever. He became known as the expert on languages and culture of southern Siouan peoples, although he also studied tribes of the Southwest and Northwest.

Dorsey also collected much material on beliefs and institutions, although most of his manuscripts have not been published. Some of the many stories he collected from the Ponca and Osage have been published, and are being used in an Omaha-language curriculum project at the University of Nebraska–Lincoln.
