21NIP (model theory) — In model theory, a branch of mathematical logic, a complete theory T is said to satisfy NIP (or not the independence property ) if none of its formulae satisfy the independence property, that is if none of its formulae can pick out any given… …
22Davson-Danielli model — In 1935, Hugh Davson and James Danielli proposed a model to explain the cell membrane consisting of a phospholipid bilayer between two layers of globular protein. Hydrophilic heads of phospholipids are towards proteins, forming a hydrophilic zone …
23Sliding filament model — Ratchet mechanism redirects here (it is the name given in some textbooks to the sliding filament mechanism). For the mechanical device, see Ratchet (device) The sliding filament theory describes a process used by muscles to contract. It was… …
24Osipkov–Merritt model — Osipkov Merritt distribution functions, derived from galaxy models obeying Jaffe s law in the density. The isotropic model, f = f(E), is plotted with the heavy line. Osipkov–Merritt models (named for Leonid Osipkov and David Merritt) are… …

26compound-nucleus model — ▪ nuclear physics description of atomic nuclei proposed (1936) by the Danish physicist Niels Bohr (Bohr, Niels) to explain nuclear reactions as a two stage process comprising the formation of a relatively long lived intermediate nucleus and …
27Antioxidant — Model of the antioxidant metabolite glutathione. The yellow sphere is the redox active sulfur atom that provides antioxidant activity, while the red, blue, white, and dark grey spheres represent oxygen, nitrogen, hydrogen, and carbon atoms,… …
28Bicycle and motorcycle dynamics — A computer generated, simplified model of bike and rider demonstrating an uncontrolled right turn. An …
29Stable theory — For differential equations see Stability theory. In model theory, a complete theory is called stable if it does not have too many types. One goal of classification theory is to divide all complete theories into those whose models can be… …
