The metastability of silica glass, for example, is characterised by lifetimes on the order of 10 98 years [4] (as compared with the lifetime of the universe, which is thought to be around 1.3787 × 10 10 years). [5] Sandpiles are one system which can exhibit metastability if a steep slope or tunnel is present. Sand grains form a pile due to ...
Metastability is basically a theory of how global integrative and local segregative tendencies coexist in the brain. [ 17 ] [ 18 ] The Operational Architectonics is centered on the fact that in the metastable regime of brain functioning, the individual parts of the brain exhibit tendencies to function autonomously at the same time as they ...
A scalar field φ (which represents physical position) in a false vacuum. The energy E is higher in the false vacuum than that in the true vacuum or ground state, but there is a barrier preventing the field from classically rolling down to the true vacuum.
A nuclear isomer is a metastable state of an atomic nucleus, in which one or more nucleons (protons or neutrons) occupy excited state levels (higher energy levels). ). "Metastable" describes nuclei whose excited states have half-lives 100 to 1000 times longer than the half-lives of the excited nuclear states that decay with a "prompt" half life (ordinarily on the order of 10
Such architectures can form a circuit guaranteed free of metastability (below a certain maximum clock frequency, above which first metastability, then outright failure occur), assuming a low-skew common clock. However, even then, if the system has a dependence on any continuous inputs then these are likely to be vulnerable to metastable states.
In biology, optimality models are a tool used to evaluate the costs and benefits of different organismal features, traits, and characteristics, including behavior, in the natural world. This evaluation allows researchers to make predictions about an organism's optimal behavior or other aspects of its phenotype .
Static equilibrium (economics), the intersection of supply and demand in any market; Sunspot equilibrium, an economic equilibrium in which non-fundamental factors affect prices or quantities; Underemployment equilibrium, a situation in Keynesian economics with a persistent shortfall relative to full employment and potential output
Biobased economy, bioeconomy or biotechonomy is an economic activity involving the use of biotechnology and biomass in the production of goods, services, or energy. The terms are widely used by regional development agencies, national and international organizations, and biotechnology companies.
