Sentence examples for improved divergence from inspiring English sources
Although the present study has yielded improved divergence time estimates, it is possible that the estimates of the time of origin for some genera such as Ottelia, Vallisneria, Najas and Blyxa may have been affected by under-representation in sampling.
Brandley et al. [34] demonstrated that accommodating different rates of evolution among subsets of DNA data may improve divergence time estimation, especially when different subsets of the data evolve at different rates.
Finally, extensive analyses of this data set have demonstrated that the use of models that account for rate heterogeneity among subsets of the DNA dramatically improve divergence date estimates and help mitigate potential problems inherent in using distantly related age calibrations [34].
This means that for a given set of calibration information, simply augmenting the number of sequences would not be sufficient to improve divergence time estimates.
MtDNA may have further utility in making progress on the problem, as our analysis of posterior credibility interval widths indicates that longer sequences would likely improve divergence time estimates.
As it moved towards the west and subsequently southwards, improving upper air divergence allowed the system to intensify, reaching tropical cyclone intensity on the evening of 11 December and thus attaining the name John.
Allowing for a higher sequence divergence improved the mapping (i.e.: fewer broken pairs).
In this experiment, divergence features improved the performance only slightly when combined with other standard features (Table 7).
My results demonstrate that using alternative priors on parameters and divergence models improved the behavior of the msBayes model.
By reparameterizing the model, introducing more flexible priors on demographic and divergence-time parameters, and implementing a non-parametric Dirichlet-process prior over divergence models, I improved the robustness, accuracy, and power of the method for estimating shared evolutionary history across taxa.
An alternative solution for improving accuracy on divergence time estimates of basal arioid nodes could come from assigning additional ariid fossils to particular subclades.
