Branch transition rate: a new metric for improved branch classification analysis

M. Haungs, P. Sallee, M. Farrens
Proceedings Sixth International Symposium on High-Performance Computer Architecture. HPCA-6 (Cat. No.PR00550)  
We propose a new metric for branch classification: branch transition rate, which is defined as the number of times a branch changes direction between taken and not taken during execution.  ...  We show that transition rate is a more appropriate indicator of branch behavior than taken rate for determining predictor performance.  ...  In this paper, we introduce a new metric for branch behavior, branch transition rate.  ...

over taken rate and 15.0% over transition rate for the workloads in this study.  ...  Unlike the existing taken rate or transition rate, DPI directly measures the regularity of the patterns in per-address branch history, and hence is more accurate in branch classification.  ...  Comparison with Conventional Metrics Now that we have demonstrated that DPI is a useful metric for branch classification, we compare this metric with the conventional taken rate and transition rate metrics  ...

Applications of Codon and Rate Variation Models in Molecular Phylogeny

Eric E. Schadt, Janet S. Sinsheimer, Kenneth Lange

HIGH RATES OF EVOLUTION PRECEDED THE ORIGIN OF BIRDS

Mark N. Puttick, Gavin H. Thomas, Michael J. Benton
2014 Evolution  
The high evolutionary rates arose primarily from a reduction in body size, as there were no increased rates of forelimb evolution.  ...  The origin of birds (Aves) is one of the great evolutionary transitions.  ...  We also thank Chris Venditti for advice and Frances Dunn for data compilation in the Bristol Palaeontology Laboratory. All silhouettes in Figure 1 were downloaded from http://phylopic.org.  ...

Estimation of Rearrangement Break Rates Across the Genome [article]

Christopher Hann-Soden, Ian Holmes, John W. Taylor
2018 bioRxiv   pre-print
We phrase this problem in graph theoretic terms and find that it is a special case of the minimum cover problem for an interval graph.  ...  We implement this method as a Python program, named BRAG, and use it to estimate the break rates in the genome of the model Ascomycete mold, Neurospora crassa.  ...  Improving the sensitivity of the break rate estimate is best achieved by adding genomes to the analysis that are distantly related to all other individuals, as deeper branches added to the tree add more  ...
