Unlike extant indexes, the CDC (Codon Deviation Coefficient) index effectively considers background nucleotide compositions and does not require any prior knowledge of reference gene sets [ 22].
There is considerable evidence in extant studies that index membership is beneficial, both for shareholders and managers.
This allows reconstruction of the NO power time series back nearly 70 years with extant databases of these indices.
Extant ungulates with hypsodonty indices close to 1.0 are Okapia johnstoni (1.18), classified as browser in closed habitat, as well as Giraffa camelopardalis (1.2) and Odocoileus virginianus (1.23) mixed-habitat browsers [ 1].
This is particularly evident in gelada baboons, which display enhanced manual feeding capabilities [29] thanks to displaying the highest opposability index among extant primates, including humans [28].
This allows extension of the fit back in time with the extant databases of the three standard indices.
This has enabled reconstruction of the NO power time series back to 1947 using extant databases of the F10.7 solar radio flux, the Ap index, and the Dst index.
However, we included these indices primarily for exploratory purposes and, based on the extant literature, we did not expect strong and consistent relationships between HF-HRVsleep and either subjective or objective sleep quality.
In a seminal 1915 paper, Bailey and Sinnott proposed "a botanical index of Cretaceous and Tertiary climates" [1]: in extant mesic floras, the proportion of woody "dicot" species that have untoothed leaf margins (NT) is positively related to mean annual temperature (MAT), and thus quantifying untoothed taxa in fossil floras is informative about past temperatures.
A current and future challenge will be how the combination of biomonitoring, in-home measurements, and extant environmental data [as assembled and integrated in a exposure index (EI)] can be linked effectively to define exposures in the NCS (Lioy et al. 2009).
