Based on estimated divergence ages and unresolved relationships among gibbon taxa on various levels, several radiation-like splitting events are indicated, which suggest a complex biogeographic history of gibbons.
In 1988 60 females (14+years) were found while 43 females were expected to be found (based on the estimated age distribution and sample size), and 48 males (14+years) were found compared to the 32 expected.
For each duration of ART, life tables based on estimated mortality rates by sex, age, latest CD4+ cell count and viral suppression (HIV-1 RNA <400 copies/ml), were used to estimate expected age at death for ages 20 85 years.
This new classification of kidney disease, launched by the American Kidney Foundation [ 24], is based on estimated GFR calculated from serum creatinine, age and sex.
The earliest evidence for a terrestrial connection to North America is 19 Ma, based on an estimated age of 19.12 19.83 Ma of the pectinid bivalves found 2 m below the land mammal fossils in the upper Culebra Formation (Section 3 in Figure 6).
Mangrove species generation length, defined as the median age of a reproducing individual based on the estimated age at earliest reproduction and the estimated age at oldest reproduction [35], was conservatively estimated to range between 10 and 40 years based on recent aging techniques developed for Rhizophora, Avicennia and Sonneratia spp. [46] [48].
The actual time of sample collection was corrected per sample based on the estimated age of the sample.
One female (R) was first seen as a subadult in her natal group and her birth was back-dated based on her estimated age.
For the root age of Vitaceae, Nie et al. (2010) fixed the split between Vitaceae and Leea as 85 ± 4 based on the estimated age of 78-92 Ma by Wikström et al. (2001).
The first method historically was the "quotient IQ", based on estimating a "mental age" of the test-taker (rounded to a specified number of years and months), which was then divided by the test-taker's "chronological age" (rounded to a specified number of years and months).
