Sentence examples for an expansion model from inspiring English sources

Here we show that phylogenetically corrected diversity curves for "fish" (actinopterygians and elasmobranchs) during the last 200 million years fit an equilibrium model in the marine realm and an expansion model in the freshwater realm.

Significant SSD or Raggedness Index values indicate that an expansion model is rejected by the data.

Additional efforts could focus on fully transitioning this type of education-support program to the public sector and developing an expansion model to reach pasantes throughout Mexico and Latin America.

In East Asia we see strong evidence for selection at the C allele of rs1800414 using the REHH test in both the constant population size model (Fig.  10a, b) and the bottleneck with an expansion model (supplemental Fig. 5).

Additionally, using the least-squares approach, there was no significant difference between observed and simulated data under an expansion model for either form (blunts: SSd, P = 0.108; Harpending's raggedness index, P = 0.116; sharps: SSd, P = 0.1680; Harpending's raggedness index, P = 0.1000).

When an expansion model could not be rejected, we estimated the time of expansion (t) from τ =  2ut, where τ is calculated as the time to expansion in mutational units, and u is the mutation rate per generation for the whole sequence.

We confirmed these results using a bottleneck followed by an exponential expansion model and saw the same results (supplemental Fig. 3).

Four models were tested: (i) a standard neutral model (SNM), (ii) a population expansion model (PEM), (iii) an instant population size change model (ICM), and (iv) a bottleneck model (BNM).

Under a doubly selective propagation condition, a basis expansion model (BEM) is deployed as a fitting parametric model for capturing the time-variation of the MU downlink channels and for reducing the number of the channel parameters.

We examined mismatch distributions based on a population expansion model in a maximum likelihood framework using ARLEQUIN [53] with 1000 bootstrap iterations.

The unimodal mismatch distribution fitting a population expansion model with a high bootstrap support (0.88 and 0.83 for pure demographic expansion and spatial expansion respectively, Figure 3A) and the negative values of Tajima's D and Fu's F s statistics (D = −1.20, p = 0.100; F s  = −4.65, p = 0.003) further support a scenario of population expansion.
