Therefore, the two patterns, IntraR and InterR extracted from the tree, use the idea of long-branch retraction and short-branch contraction for polytomy identification.
The PolyPhy method takes into account different tree topological properties between dichotomy and polytomy, such as long-branch retraction and short-branch contraction, and quantifies these properties as comparable rates among different sub-branches.
Other than considering genome-scale distances between all pairs of species, PolyPhy also takes into account different properties of tree topology between dichotomy and polytomy, such as long-branch retraction and short-branch contraction, and quantifies these properties into comparable rates among different sub-branches.
In total, expansions outnumber contractions on the human, chimp, mouse, rodent, and ingroup branches (Table 2).
Importantly, PDF has been shown to regulate tracheal branching in the hindgut, which could also affect muscle contractions (Linneweber et al Cell 2014).
The filopodia are hyaline, slender, and often branching structures in which contraction of microfilaments moves the organism's body along the substrate, even if it is bearing a relatively heavy test or shell.
Branching leads to a contraction of the polymer chain in terms of the hydrodynamic volume.
Numerical simulations unified the roles of actin filament branching and crosslinking during actomyosin contraction.
Ten types of ECG arrhythmias (normal beat, sinus bradycardia, ventricular tachycardia, sinus arrhythmia, atrial premature contraction, paced beat, right bundle branch block, left bundle branch block, atrial fibrillation and atrial flutter) obtained from MIT-BIH database were analyzed.
Viterbi P-values were computed for each significant tribe to assess significant expansion or contraction along a specific branch.
