Sentence examples for heterogeneity rate from inspiring English sources

The second prior is the heterogeneity rate.

For the transition/transversion bias, the fourth prior, we chose to take a bias directly calculated on the basis of nucleotide sequences by the software MEGA4 [45] (61.432 for twelve sequences/254.911 for nine sequences/9.405 for eight sequences/15.683 for seven sequences; this value is calculated for a heterogeneity rate of 0.26).

In each model we proposed several values for each prior: a range of values for the population size, two values for the growth rate, several values for the migration rate, a range of values for the mutation rate, one value for the heterogeneity rate and four lengths of the nucleotide sequences.

Therefore, although heterotachy is accounted for, these simulations largely ignored a major kind of heterogeneity: rate variation across lineages.

For each set of aligned sequences, we implemented a mixed model of amino acid substitution, with gamma-correction for heterogeneity rate among residues and correction for invariable residues.

The heterogeneity rate was estimated by gamma distribution with 8 rate categories and the α-parameter was estimated from the dataset.

Specific process-pairs investigated include physical nonequilibrium vs. physical heterogeneity, rate-limited sorption vs. nonlinear sorption, and sorption vs. transformation reactions.

The GTR model with gamma-distributed substitution heterogeneity rates was used, with base frequencies estimated by maximum likelihood, and 1000 bootstrap pseudoreplicates to assess clade support.

Our results also suggest that heterogeneity in rate dynamics among viral lineages may exist, and can affect evolutionary inference.

Three scenarios with different degrees of heterogeneity in rates of partner change were considered.

The selected model of evolution was the General Time Reversible model with gamma distributed heterogeneity of rates (GTR gamma).
