Different polytopal realizations of the G-associahedron were constructed [CD06, Dev09, Pos09, FS05, Zel06], but all with the same normal fan: its rays are the characteristic vectors of the tubes of G and its cones are the cones over the nested sets of G.
Such constructions would yield in particular geometrically distinct normal fans and different poset structures on maximal nested sets, exactly as C.
Example 11 (Unsigned trees) When T has only negative vertices, the spines are just the inclusion posets of the nested sets of N(T).
Only the second-round amplicon of the 3 nested sets of nested primer pairs (2, 3, and 9) was considered because the second round increased the total number of positive specimens over the first round.
The kitchen pieces such as creamers, sugar bowls and nested sets of three mixing bowls get snapped up quickly, says Lazzarra, "especially sets of bowls, as they're pretty rare.
As we move through this ambient array, invariant ratios of illumination intensity presented in temporal sequence constitute a structure or texture in the form of deeply nested sets of invariant relations of illumination; these nested sets of invariant ratios of illumination are what are registered or picked up by the perceptual system.
In a collection of nested sets either any two are disjoint or one is a subset of the other.
He represents it not as a graph nor as nested sets but by a structuralist formula a:b::[b.

dispar, nested sets of primers (designated E-1/E-2, Eh-1/Eh-2, and Ed-1/Ed-2) were used, as described (11), to detect E.
