  4. Boundary element method - Wikipedia

    en.wikipedia.org/wiki/Boundary_element_method

    The boundary element method (BEM) is a numerical computational method of solving linear partial differential equations which have been formulated as integral equations (i.e. in boundary integral form), including fluid mechanics, acoustics, electromagnetics (where the technique is known as method of moments or abbreviated as MoM), [1] fracture mechanics, [2] and contact mechanics.

    The exceptions are in any case not very relevant for chemistry because the energy difference between them and the expected configuration is always quite low. [ 32 ] The ( n − 1)d orbitals that are involved in the transition metals are very significant because they influence such properties as magnetic character, variable oxidation states ...

  6. Compatibility (geochemistry) - Wikipedia

    en.wikipedia.org/wiki/Compatibility_(geochemistry)

    Compatibility is a term used by geochemists to describe how elements partition themselves in the solid and melt within Earth's mantle.In geochemistry, compatibility is a measure of how readily a particular trace element substitutes for a major element within a mineral.

  7. Finite element method - Wikipedia

    en.wikipedia.org/wiki/Finite_element_method

    The finite difference method (FDM) is an alternative way of approximating solutions of PDEs. The differences between FEM and FDM are: The differences between FEM and FDM are: The most attractive feature of the FEM is its ability to handle complicated geometries (and boundaries) with relative ease.

  8. Retrotransposon - Wikipedia

    en.wikipedia.org/wiki/Retrotransposon

    LINE1s can only retrotranspose in some cases to form different chromosome structures contributing to differences in genetics between individuals. [17] There is an estimate of 80–100 active L1s in the reference genome of the Human Genome Project, and an even smaller number of L1s within those active L1s retrotranspose often.
