    en.wikipedia.org/wiki/Supplemental_jurisdiction

    Ancillary jurisdiction is a form of supplemental jurisdiction that allows a United States federal court to hear non-federal claims sufficiently logically dependent on a federal "anchor claim" (i.e., a federal claim serving as the basis for supplemental jurisdiction), despite that such courts would otherwise lack jurisdiction over such claims.

  4. Ancillary statistic - Wikipedia

    en.wikipedia.org/wiki/Ancillary_statistic

    Conversely, given i.i.d. normal variables with known mean 1 and unknown variance σ 2, the sample mean ¯ is not an ancillary statistic of the variance, as the sampling distribution of the sample mean is N(1, σ 2 /n), which does depend on σ 2 – this measure of location (specifically, its standard error) depends on dispersion.

    Auxiliaries in the Roman army were recruited from provincial tribal groups who did not have Roman citizenship.As the Roman army of the Republican and early Empire periods was essentially based on the heavy infantry who made up the legions, it favored the recruitment of auxiliaries that excelled in supplementary roles.

The term is also used in a civilian management context describing comparable hierarchical structures of authority. Such structures are included in ...

    Ancillary packets located in the horizontal blanking region (after EAV but before SAV), regardless of line, are known as horizontal ancillary data, or HANC. HANC is commonly used for higher-bandwidth data, and/or for things that need to be synchronized to a particular line; the most common type of HANC is embedded audio .

  8. Equivalent definitions of mathematical structures - Wikipedia

    en.wikipedia.org/wiki/Equivalent_definitions_of...

    It means that the two structures on N are equivalent by means of the two procedures. The two isomorphic implementations of natural numbers mentioned in the previous section are isomorphic as triples ( N ,0, S ), that is, structures of the same signature (0, S ) consisting of a constant symbol 0 and a unary function S .

  9. Glossary of structural engineering - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_structural...

    Bent (structural) – Bents are the building blocks that define the overall shape and character of a structure. They do not have any sort of pre-defined configuration in the way that a Pratt truss does. Rather, bents are simply cross-sectional templates of structural members, i.e., rafters, joists, posts, pilings, etc., that repeat on parallel ...
