Sentence examples for constrain age from inspiring English sources

Since we would expect that age would be exponentially related to cancer, and for breast and uterine cancer the slope of the exponential line would change after menopause, the use of age categories did not constrain age to be linearly related to the outcome.

To better delimit the search space and constrain ages based on several known fossils, we bounded the holometabolan root age to fall between 360 Ma (maximum age) or the approximate age of the Neoptera (a group that includes the majority of winged insects), and 280 Ma, a hypothetical minimum age for Holometabola [ 1].

These astroseismologi-cal studies are further keys to obtain a well constrained age (goal: 10% accuracy; Kjeldsen et al., 2009) of stars, and therefore planetary systems.

We then compare this predicted level of the dependent variable under the constrained age trend to the actual level observed in the first year that the restriction is eased.

In Canada, older doctors were slightly more satisfied in their job (B = 0.04, p < 0.01), whereas in the U.S. younger doctors were more satisfied (B = -0.09, p < 0.01) and in Norway there was no age difference (probably due to the constrained age distribution of the sample).

This finding reflects growing concerns that constraining ages based on present day distributions that reflect putative ancient vicariant events may bias our understanding of the evolutionary pathways that underlie the generation of modern biodiversity [ 135].

To further constrain the age model, we compared the ages of event layers with historical flood events.

137Cs is a fallout product of nuclear testing, which enables us to constrain the age of the 137Cs peak to the peak age of nuclear testing 1963 A.D. on the basis of the record of nuclear testing [Delaune et al. 1978].

The regional tephra layers also constrain the age of sediment in this section.

Paleomagnetic polarity and marine microfossil data, including biostratigraphic data for planktonic foraminifera, radiolaria, and diatoms, constrain the age of the shallow marine sediments within the Mizunami Group (Kawamura et al. 2011, and references therein).

We have conducted a paleomagnetic study of drill cores and gravity cores newly taken from the northern part of the PHS Plate in order to better constrain the age and amount of the northward shift.
