For the limited number of patients in our follow-up survey, our correlation date between the status of detectable MAGE transcripts in blood and the prognosis of the patients is preliminary.
Even though the idea of learning through correlations dates further back in the past (James 1890), correlation-based learning is now generally called Hebbian learning.
Ancient sample ages for tip-dating were inferred through stratigraphic correlation (layer dating); any samples without dates, or with approximate or infinite ages were not included in the BEAST analysis (see additional file 2).
The results of such research have important ramifications in stratigraphic correlation, age dating, and reconstructing past movements of the Earth's crust.
This correlation and dating provided the "capping" minimum age for the Herto hominids, which are therefore firmly placed within the 154,000 to 160,000 year window of time.
Regional correlation of dated weathered land surfaces provides the necessary constraints to test long-term continental landscape evolution models, but major challenges remain in properly dating these surfaces.
Additional themes that could be investigated under the umbrella of their relevance to the study of macroevolution include: stratigraphic correlation and dating, phylogentics and systematics, biogeography, data gaps or biases (temporal or spatial), ecological roles or niches, environmental reconstruction, or climate reconstruction and cyclicity.
ESS, effective sample size; R, Pearson correlation between date of isolation and maximum likelihood tree branch length.
Through new geological correlations and dating within the Bed II sequence and a new stratigraphic description of the site, new chronological and contextual information is provided for this site.
And John Hoffecker, an archaeologist at the University of Colorado, Boulder, says that the data sets behind the new curve will allow a more-precise correlation between radiocarbon dates and prehistoric climate reconstructions based on Greenland ice cores and other proxy indicators of ancient weather.
