Contraction (operator theory)
In operator theory, a bounded operator T: X → Y between normed vector spaces X and Y is said to be a contraction if its operator norm ||T || ≤ 1. This notion is a special case of the concept of a contraction mapping, but every bounded operator becomes a contraction after suitable scaling. The analysis of contractions provides insight into the structure of operators, or a family of operators. The theory of contractions on Hilbert space is largely due to Béla Szőkefalvi-Nagy and Ciprian Foias.

Béla Szőkefalvi-Nagy
Béla Szőkefalvi-Nagy [beːlɒ søːkɛfɒlvi nɒɟ] (29 July 1913, Kolozsvár – 21 December 1998, Szeged) was a Hungarian mathematician. His father, Gyula Szőkefalvi-Nagy was also a famed mathematician. Szőkefalvi-Nagy collaborated with Alfréd Haar and Frigyes Riesz, founders of the Szegedian school of mathematics. He contributed to the theory of Fourier series and approximation theory. His most important achievements were made in functional analysis, especially, in the theory of Hilbert space operators. He was editor-in-chief of the Zentralblatt für Mathematik, the Acta Scientiarum Mathematicarum,  and the Analysis Mathematica. He was awarded the Kossuth Prize in 1953, along with his co-author F. Riesz, for his book Leçons d'analyse fonctionnelle.  He was awarded the Lomonosov Medal in 1979. The Béla Szőkefalvi-Nagy Medal honoring his memory is awarded yearly by Bolyai Institute.
Cuttlebone
Cuttlebone, also known as cuttlefish bone, is a hard, brittle internal structure (an internal shell) found in all members of the family Sepiidae, commonly known as cuttlefish, within the cephalopods. In other cephalopod families it is called a gladius.

Cuttlebone is composed primarily of aragonite. It is a chambered structure that the animal can fill with gas or liquid for buoyancy control. On the ventral (bottom) side of the cuttlebone is the highly modified siphuncle; this is the organ with which the cuttlebone is filled with gas or liquid. The microscopic structure of cuttlebone consists of narrow layers connected by numerous upright pillars.

Depending on the species, cuttlebones implode at a depth of 200 to 600 metres (660 to 1,970 ft). Because of this limitation, most species of cuttlefish live on the seafloor in shallow water, usually on a continental shelf.

Upon the death of a cuttlefish, its body decomposes, leaving only the cuttlebone, which often washes up on beaches.

Brittleness
A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a sharp snapping sound.

When used in materials science, it is generally applied to materials that fail when there is little or no plastic deformation before failure. One proof is to match the broken halves, which should fit exactly since no plastic deformation has occurred.
Tyromyces toatoa
Tyromyces toatoa is a species of poroid fungus found in New Zealand. It was described as a new species by G. H. Cunningham in 1965. The type collections were made by Joan Dingley, who found the fungus in Taupō, Mount Ruapehu, near Whakapapa Stream. She found it fruiting on the bark of dead branches and trunks of Phyllocladus alpinus, at an elevation of 1,000 metres (3,300 ft). The specific epithet toatoa  evokes the Māori name of the host plant.

Taupō
Taupō, sometimes written Taupo, is a town located in the central North Island of New Zealand. It is situated on the edge of Lake Taupō, which is the largest freshwater lake in New Zealand. Taupō was constituted as a borough in 1953. It has been the seat of Taupō District Council since the council was formed in 1989.

2-oxoglutarate/L-arginine monooxygenase/decarboxylase (succinate-forming)
2-oxoglutarate/L-arginine monooxygenase/decarboxylase (succinate-forming) (EC 1.14.11.34, ethylene-forming enzyme, EFE) is an enzyme with systematic name L-arginine,2-oxoglutarate:oxygen oxidoreductase (succinate-forming). This enzyme catalyses the following chemical reaction

(1a) 2-oxoglutarate + L-arginine + O2  succinate + CO2 + L-hydroxyarginine

(1b) L-hydroxyarginine  guanidine + (S)-1-pyrroline-5-carboxylate + H2O

2-oxoglutarate/L-arginine monooxygenase/decarboxylase catalyses two cycles of the ethylene-forming reaction.

Ethylene
Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C2H4 or H2C=CH2. It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).

Ethylene is widely used in the chemical industry, and its worldwide production (over 225 million tonnes in 2022) exceeds that of any other organic compound. Much of this production goes toward creating polyethylene, which is a widely used plastic containing polymer chains of ethylene units in various chain lengths. Production emits greenhouse gases, including methane from feedstock production and carbon dioxide from any non-sustainable energy used.

Ethylene is also an important natural plant hormone and is used in agriculture to induce ripening of fruits. The hydrate of ethylene is ethanol.

After retiring from racing he became a successful stallion, with his progeny including Prix de l'Arc de Triomphe winner Rail Link and King George VI and Queen Elizabeth Stakes winner Harbinger. He also became Champion sire in France in 2006.

Stallion
A stallion is an adult male horse that has not been gelded (castrated). Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as mares, and castrated males, called geldings.

Temperament varies widely based on genetics and training, but because of their instincts as herd animals, they may be prone to aggressive behavior, particularly toward other stallions, and thus require careful management by knowledgeable handlers. With proper training and management, stallions are effective equine athletes at the highest levels of many disciplines, including horse racing, horse shows, and international Olympic competition.

"Stallion" is also used to refer to males of other equids, including zebras and donkeys.
