  2. Raising and lowering indices - Wikipedia

    en.wikipedia.org/wiki/Raising_and_lowering_indices

    Concretely, in the case where the vector space has an inner product, in matrix notation these can be thought of as row vectors, which give a number when applied to column vectors. We denote this by V ∗ := Hom ( V , K ) {\displaystyle V^{*}:={\text{Hom}}(V,K)} , so that α ∈ V ∗ {\displaystyle \alpha \in V^{*}} is a linear map α : V → K ...

  3. Disposition index - Wikipedia

    en.wikipedia.org/wiki/Disposition_index

    Disposition index, but not insulin resistance, can predict type 2 diabetes in persons with normal blood glucose levels, but who do not have a family history (genetic predisposition) to type 2 diabetes. [14] Disposition index can be increased by aerobic exercise, but only to the extent that insulin sensitivity is improved. [15]

  4. Droop quota - Wikipedia

    en.wikipedia.org/wiki/Droop_quota

    In proportional quota-based systems such as STV or expanding approvals, these excess votes can be transferred to other candidates to preventing them from being wasted. [ 4 ] The Droop quota was first suggested by the English lawyer and mathematician Henry Richmond Droop (1831–1884) as an alternative to the Hare quota .

    en.wikipedia.org/wiki/JMP_(statistical_software)

    The Herzenberg Laboratory at Stanford has integrated JMP with the Fluorescence Activated Cell Sorter (FACS). The FACS system is used to study HIV, cancer, stem-cells and oceanography. [71] JMP Pro is also used by research consortium Target Malaria in Europe and Africa through a license with its lead institution, Imperial College London.

  7. Symmetric level-index arithmetic - Wikipedia

    en.wikipedia.org/wiki/Symmetric_level-index...

    The level-index (LI) representation of numbers, and its algorithms for arithmetic operations, were introduced by Charles Clenshaw and Frank Olver in 1984. [ 1 ] The symmetric form of the LI system and its arithmetic operations were presented by Clenshaw and Peter Turner in 1987.

  8. Fixation index - Wikipedia

    en.wikipedia.org/wiki/Fixation_index

    The fixation index (F ST) is a measure of population differentiation due to genetic structure. It is frequently estimated from genetic polymorphism data, such as single-nucleotide polymorphisms (SNP) or microsatellites. Developed as a special case of Wright's F-statistics, it is one of the most commonly used statistics in population genetics ...
