The theta-criterion (also named θ-criterion) is a constraint on x-bar theory that was first proposed by Noam Chomsky as a rule within the system of principles of the government and binding theory, called theta-theory (θ-theory). As theta-theory is concerned with the distribution and assignment of theta-roles (a.k.a. thematic roles), the theta ...
The binding of a ligand to a macromolecule is often enhanced if there are already other ligands present on the same macromolecule (this is known as cooperative binding). The Hill equation is useful for determining the degree of cooperativity of the ligand(s) binding to the enzyme or receptor.
The repeated independent evolution of nylonase in two different strains of Flavobacterium and one strain of Pseudomonas. The myoglobin from the abalone Sulculus diversicolor has a different structure from normal myoglobin but serves a similar function — binding oxygen reversibly. "The molecular weight of Sulculus myoglobin is 41kD, 2.5 times ...
In government and binding theory this is known as proper government. Proper government occurs either if the empty position is governed by a lexical category (especially if it is not a subject) (theta-government) or if it is coindexed with a maximal projection which governs it (antecedent-government). The ECP has been revised many times and is ...
Neutral theory – Theory of evolution by changes at the molecular level; Shifting balance theory – One version of the theory of evolution; Price equation – Description of how a trait or gene changes in frequency over time; Coefficient of relationship – Measure of biological relationship between individuals
Government and binding (GB, GBT) is a theory of syntax and a phrase structure grammar in the tradition of transformational grammar developed principally by Noam Chomsky in the 1980s. [ 1 ] [ 2 ] [ 3 ] This theory is a radical revision of his earlier theories [ 4 ] [ 5 ] [ 6 ] and was later revised in The Minimalist Program (1995) [ 7 ] and ...
The term refers to the relation between an indexed constituent and its trace t, e.g., the relation of whom and t in the example (1) Whom i do you think you are kidding t i? In (1), the constituent (whom) and its trace (t) are said to form a "chain". In syntax, Move α is the most general formulation of possible movement permitted by a rule.
In mathematics, the theta correspondence or Howe correspondence is a mathematical relation between representations of two groups of a reductive dual pair. The local theta correspondence relates irreducible admissible representations over a local field , while the global theta correspondence relates irreducible automorphic representations over a ...
