Most pleasing to the eye are rules generating nested patterns like those of a crystal or a snowflake, or the markings on a seashell, the branching of a leaf, the spiral of a pine cone.
The seed bank composition changed with time since fragmentation started, triggered by the deterministic loss of grassland species, generating nested subsets of the seed banks of semi-natural grasslands.
Instead, these genes have a tendency to insert into the reverse transcriptase genes encoded by other group II introns, generating nested introns.
The classical FS generates nested models, adding the next best ranked feature, one at a time, and selects the model that resulted in the maximum fitness.
The selection of α in the proposed algorithm is analogous to pruning in the traditional C&RT programs, with larger values of α generating larger trees and smaller values generating nested sub-trees.
Here it seems that none of the group II introns are inserted in archaeal open-reading frames, and have a tendency to insert into the reverse transcriptase genes encoded by other group II introns, generating nested introns.
Using data from ∼1400 nests of 23 species, we generated nest survival curves for groups of altricial species defined by nest substrate (ground, shrub, tree, or culvert).
As a basis towards this, we use the knowledge base development framework that generates Nested Ripple Down Rules knowledge bases [6, 21].
Our study also indicated that helitrons with multiple termini can be generated from nested helitrons.
The cDNA from each single B cell was generated, and nested polymerase chain reaction specific for VH genes and Rag1 and Rag2 genes was performed.
