Douglas Reye
Ralph Douglas Kenneth Reye ( "rye"; 5 April 1912 – 16 July 1977) was an Australian pathologist. In 1958, he discovered a muscular disease that was later named nemaline myopathy. A brain disease he and his colleagues described in 1963 is eponymously known as Reye's syndrome. Life and career Reye attended Townsville Grammar School and the University of Sydney, where he completed undergraduate studies in medicine and was awarded a MBBS in 1937. He was later awarded an MD from the University of Sydney in 1945. Reye joined the staff of the Royal Alexandra Hospital for Children (RAHC) in 1939 as a pathologist, and remained there for all his working life. In 1965 Reye was elected as a Fellow of the Royal Australasian College of Physicians. On 16 July 1977, Reye died at the age of 65, of a ruptured abdominal aortic aneurysm at Royal North Shore Hospital, 24 hours after he had retired from the RAHC. Contributions Nemaline myopathy In 1958, Reye identified a disease that involv ...

Reye Syndrome
Reye syndrome is a rapidly worsening brain disease. Symptoms of Reye syndrome may include vomiting, personality changes, confusion, seizures, and loss of consciousness. While liver toxicity typically occurs in the syndrome, jaundice usually does not. Death occurs in 20–40% of those affected with Reye syndrome, and about a third of those who survive are left with a significant degree of brain damage. The cause of Reye syndrome is unknown. It usually begins shortly after recovery from a viral infection, such as influenza or chickenpox. About 90% of cases in children are associated with aspirin (salicylate) use. Inborn errors of metabolism are also a risk factor. The syndrome is associated with changes on blood tests such as a high blood ammonia level, low blood sugar level, and prolonged prothrombin time. Often, the liver is enlarged in the syndrome. Prevention is typically by avoiding the use of aspirin in children. When aspirin was withdrawn for use in children in the ...

Theodor Reye
Karl Theodor Reye (born 20 June 1838 in Ritzebüttel, Germany and died 2 July 1919 in Würzburg, Germany) was a German mathematician. He contributed to geometry, particularly projective geometry and synthetic geometry. He is best known for his introduction of configurations in the second edition of his book, ''Geometrie der Lage'' (Geometry of Position, 1876). The Reye configuration of 12 points, 12 planes, and 16 lines is named after him. Reye also developed a novel solution to the following three-dimensional extension of the problem of Apollonius: Construct all possible spheres that are simultaneously tangent to four given spheres. Life Reye obtained his Ph.D. from the University of Göttingen in 1861. His dissertation was entitled "Die mechanische Wärme-Theorie und das Spannungsgesetz der Gase" (The mechanical theory of heat and the potential law of gases). Mathematical work Reye worked on conic sections, quadrics and projective geometry. Reye's work on linear mani ...

Reye Configuration
In geometry, the Reye configuration, introduced by , is a configuration of 12 points and 16 lines. Each point of the configuration belongs to four lines, and each line contains three points. Therefore, in the notation of configurations, the Reye configuration is written as . Realization The Reye configuration can be realized in three-dimensional projective space by taking the lines to be the 12 edges and four long diagonals of a cube, and the points as the eight vertices of the cube, its center, and the three points where groups of four parallel cube edges meet the plane at infinity. Two regular tetrahedra may be inscribed within a cube, forming a stella octangula; these two tetrahedra are perspective figures to each other in four different ways, and the other four points of the configuration are their centers of perspectivity. These two tetrahedra together with the tetrahedron of the remaining 4 points form a desmic system of three tetrahedra. Any two disjoint spheres in thre ...

Reye's Hypothesis
The Archard wear equation is a simple model used to describe sliding wear and is based on the theory of asperity contact. The Archard equation was developed much later than (sometimes also known as energy dissipative hypothesis), though both came to the same physical conclusions, that the volume of the removed debris due to wear is proportional to the work done by friction forces. Theodor Reye's model became popular in Europe and it is still taught in university courses of applied mechanics. Until recently, Reye's theory of 1860 has, however, been totally ignored in English and American literature where subsequent works by Ragnar Holm and John Frederick Archard are usually cited. In 1960, and Mikhail Alekseevich Babichev published a similar model as well. In modern literature, the relation is therefore also known as Reye–Archard–Khrushchov wear law. In 2022, the steady-state Archard wear equation was extended into the running-in regime using the bearing ratio curve repres ...
