Three examples of Turing patterns Six stable states from Turing equations, the last one forms Turing patterns. The Turing pattern is a concept introduced by English mathematician Alan Turing in a 1952 paper titled "The Chemical Basis of Morphogenesis" which describes how patterns in nature, such as stripes and spots, can arise naturally and autonomously from a homogeneous, uniform state.
(a) patterns of self-organisation that lead to self-organisation through morphogenesis and complexity; (b) patterns for long term evolution towards autonomy; (c) patterns that lead to the functioning of viable systems. This theory was intended to embrace the dynamics of dissipative systems using three planes. Plane of energy. Plane of information.
Cytological markers of BFB-cycle-mediated chromosomal instability: "budding" nuclei (A, C, D) and partly fragmented nucleus with double nucleoplasmic bridge (B). [ 1 ] Breakage-fusion-bridge (BFB) cycle (also breakage-rejoining-bridge cycle ) is a mechanism of chromosomal instability , discovered by Barbara McClintock in the late 1930s.
The science of pattern formation deals with the visible, (statistically) orderly outcomes of self-organization and the common principles behind similar patterns in nature. In developmental biology , pattern formation refers to the generation of complex organizations of cell fates in space and time.
In evolutionary biology, punctuated equilibrium (also called punctuated equilibria) is a theory that proposes that once a species appears in the fossil record, the population will become stable, showing little evolutionary change for most of its geological history. [1]
The first is a historical study of classical evolutionary thought, drawing extensively upon primary documents; the second is a constructive critique of the modern synthesis, and presents a case for an interpretation of biological evolution based largely on hierarchical selection, and the theory of punctuated equilibrium (developed by Niles ...
Technically, anything over 20 years old can be coined “vintage.”But when you truly think of items worth this title, your brain doesn’t go to Beanie Babies.
In the fields of nonlinear optics and fluid dynamics, modulational instability or sideband instability is a phenomenon whereby deviations from a periodic waveform are reinforced by nonlinearity, leading to the generation of spectral-sidebands and the eventual breakup of the waveform into a train of pulses.
