There is increasing evidence in support of genetics being a key factor in the development of OIH through its influence on both pain sensitivity and analgesic control. Current evidence indicates that the genetic influence stems from polymorphisms of the gene coding for the enzyme, Catechol-O-Methyltransferase (COMT). It...

In single-variable calculus, the fundamental theorem of calculus establishes a link between the derivative and the integral. The link between the derivative and the integral in multivariable calculus is embodied by the integral theorems of vector calculus:: 543ff Gradient theorem Stokes' theorem Divergence theorem Gree...

Valuation algebras Dropping the idempotency axiom leads to valuation algebras. These axioms have been introduced by (Shenoy & Shafer 1990) to generalize local computation schemes (Lauritzen & Spiegelhalter 1988) from Bayesian networks to more general formalisms, including belief function, possibility potentials, etc. (...

According to Richard Feynman, it was his former graduate student and collaborator Albert Hibbs who originally suggested to him (c. 1959) the idea of a medical use for Feynman's theoretical micromachines (see nanotechnology). Hibbs suggested that certain repair machines might one day be reduced in size to the point that...

These detect volatile compounds given off from explosives using gas chromatography.Computed tomography and walk-through body scanning (Thz radiation) may also be done. Artificial intelligence systems are also being used, for example for translation service on information stations around the airport and for reducing the...

While much of computational creativity research focuses on independent and automatic machine-based creativity generation, many researchers are inclined towards a collaboration approach. This human-computer interaction is sometimes categorized under the creativity support tools development. These systems aim to provide ...

More generally, the Bethe lattice or infinite Cayley tree is the Cayley graph of the free group on n {\displaystyle n} generators. A presentation of a group G {\displaystyle G} by n {\displaystyle n} generators corresponds to a surjective map from the free group on n {\displaystyle n} generators to the group G , {\disp...

Structured analysis and design technique (SADT) is a systems engineering and software engineering methodology for describing systems as a hierarchy of functions. SADT is a structured analysis modelling language, which uses two types of diagrams: activity models and data models. It was developed in the late 1960s by Dou...

René Descartes defined extension as the property of existing in more than one dimension, a property that was later followed up in Grassmann's n-dimensional algebra. For Descartes, the primary characteristic of matter is extension (res extensa), just as the primary characteristic of mind is thought (res cogitans).

This led to the field of statistical mechanics and the realization that gases undergo irreversible processes. In deterministic physics, all processes are time-reversible, meaning that they can proceed backward as well as forward through time. As Prigogine explains, determinism is fundamentally a denial of the arrow of ...

Projective linear transforms are collineations (planes in a vector space correspond to lines in the associated projective space, and linear transforms map planes to planes, so projective linear transforms map lines to lines), but in general not all collineations are projective linear transforms – PGL is in general a pr...
