Sentence examples for star trees from inspiring English sources

As mentioned earlier, star trees are bona fide common ancestry models that lack hierarchical structure.

Star trees model varying degrees of similarity among a set of proteins, as each branch in the star tree can be a different length, but star trees cannot account for hierarchical genealogical patterns.

For each size, trees were generated in four different ways: general trees, binary trees, star trees and trees with one node of degree surrounded by degree 3 nodes.

Second, certain models, like star trees and K&W's profile model (corresponding to their simulation), readily explain sequence similarity yet lack phylogenetic structure.

The key observation is that star trees are worse than independent origin models for the real proteins (as gauged by the model selection scores).

Unlike star trees and K&W's profile model, which can only explain sequence similarity, the common ancestry models can also explain nested hierarchical sequence correlations.

A 3D print test I ran (below) passed with flying colors and a Mario star tree topper I printed looked like it could come out of the Nintendo Store.

Distinct network topologies like star, tree, and chain architectures comprising one coordinator and some stationary nodes are considered in the simulation.

To make sure that Santa is satisfied, and you come out glowing brighter than the star tree-topper, check out which cookies you leave for Santa say about you! -Lauren Gordon, The Daily Meal.

We simulated sequences using a simple model of nucleotide evolution along a four-taxon star tree with two long and two short terminal branch lengths (Fig. 1a).

A recent theoretical study showed that under the limiting distribution for a star tree with two long branches under the Jukes-Cantor model, the posterior probability of the LBA tree is higher than that of any other tree, including the star tree itself, irrespective of the specific prior distribution used for branch lengths [41].
