TraitLab: a Matlab package for fitting and simulating binary tree-like data
Luke J. Kelly, Geoff K. Nicholls, Robin J. Ryder +1
TraitLab is a software package for simulating, fitting and analysing tree-like binary data under a stochastic Dollo model of evolution. The model also allows for rate heterogeneity…
Bayesian inference of sampled ancestor trees for epidemiology and fossil calibration
Alexandra Gavryushkina, David Welch, Tanja Stadler +1
Phylogenetic analyses which include fossils or molecular sequences that are sampled through time require models that allow one sample to be a direct ancestor of another sample. As…
Bayesian total evidence dating reveals the recent crown radiation of penguins
Alexandra Gavryushkina, Tracy A. Heath, Daniel T. Ksepka +3
The total-evidence approach to divergence-time dating uses molecular and morphological data from extant and fossil species to infer phylogenetic relationships, species divergence t…
The Imaging X-Ray Polarimetry Explorer (IXPE): Pre-Launch
Martin C. Weisskopf, Paolo Soffitta, Luca Baldini +155
Scheduled to launch in late 2021, the Imaging X-ray Polarimetry Explorer (IXPE) is a NASA Small Explorer Mission in collaboration with the Italian Space Agency (ASI). The mission w…
PEACH Tree: A Multiple Sequence Alignment and Tree Display Tool for Epidemiologists
Jordan Douglas, David Welch
PEACH Tree is an easy-to-use, online tool for displaying multiple sequence alignments and phylogenetic trees side-by-side. PEACH Tree is powerful for rapidly tracing evolutionary a…
Solid friction between soft filaments
Andrew Ward, Feodor Hilitski, Walter Schwenger +5
Any macroscopic deformation of a filamentous bundle is necessarily accompanied by local sliding and/or stretching of the constituent filaments. Yet the nature of the sliding fricti…
