Heterogeneity (disambiguation)

Heterogeneous, Heterogeneity is when several different things are mixed together and may refer to:

Physics

Chemistry

In chemical kinetics, a heterogeneous reaction is one that takes place at the interface of two or more phases, i.e. between a solid and a gas, a liquid and a gas, or a solid and a liquid.
In heterogeneous catalysis the catalyst is in a different phase from the substrate.

the state of constant fluctuation

The heterogeneity was defined by Pierre Gy [1]. See also .

Molecular biology

Heterogeneity of ion channels means diversity of different types of channels serving a specific kind of current, e.g. by channels with different constitutive subunits. ^[2]

Statistics and econometrics

See Study heterogeneity.

Taxonomy

In taxonomy, a heterogeneous taxon is a taxon that contains a great variety of individuals or sub-taxa; usually this implies that the taxon is an artificial grouping.

Genetics

In genetics, Genetic heterogeneity refers to multiple origins causing the same disorder in different individuals.

Ecology

in Landscape ecology heterogeneity is the measure of how different parts of a landscape are from one another.

Computing

Heterogeneous computing systems refer to electronic systems that utilize a variety of different types of computational units.
In the world of enterprise computing, heterogeneous data is a mix of data from two or more sources, often of two or more formats, e.g., SQL and XML.
