Axiomatic opportunities and obstacles for inferring a species tree from gene trees [PDF]

open access: yes, 2014
The reconstruction of a central tendency `species tree' from a large number of conflicting gene trees is a central problem in systematic biology. Moreover, it becomes particularly problematic when taxon coverage is patchy, so that not all taxa are ...

High Strain Rate Properties of High Strength Steel Sheets

open access: yesInternational Journal of Automotive Engineering, 2011
High strain rate properties of sheet steel largely depend on its strength level and strengthening mechanisms. The strain rate sensitivity of flow stress has a close relation with the hardness of a softer phase, which indicates superior strain rate ...

Which phylogenetic networks are merely trees with additional arcs? [PDF]

open access: yes, 2015
A binary phylogenetic network may or may not be obtainable from a tree by the addition of directed edges (arcs) between tree arcs. Here, we establish a precise and easily tested criterion (based on `2-SAT') that efficiently determines whether or not any ...

On choosing mixture components via non-local priors [PDF]

open access: yes, 2019
Choosing the number of mixture components remains an elusive challenge. Model selection criteria can be either overly liberal or conservative and return poorly-separated components of limited practical use.

Robust bayesian inference in empirical regression models [PDF]

open access: yes, 1991
Broadening the stochastic assumptions on the error terms of regression models was prompted by the analysis of linear multivariate t models in Zellner (1976).

Phylogenetic mixtures on a single tree can mimic a tree of another topology [PDF]

open access: yes, 2007
Phylogenetic mixtures model the inhomogeneous molecular evolution commonly observed in data. The performance of phylogenetic reconstruction methods where the underlying data is generated by a mixture model has stimulated considerable recent debate.

Hydrogen Embrittlement Evaluation Methods for Ultra-high Strength Steel Sheets for Automobiles

open access: yesInternational Journal of Automotive Engineering, 2010
In order to apply ultra-high strength steel sheets with tensile strength of 980MPa or higher to automobiles, it is necessary to ensure the safety of steel parts against hydrogen embrittlement (HE).

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.
