Constructing a multi-dimensional prior on the times of divergence (the node ages) of species in a phylogeny is not a trivial task, in particular, if the prior density is the result of combining different sources of information such as a speciation process with fossil calibration densities. Yang & Rannala (2006 Mol. Biol. Evol 23, 212-226. (doi:10.1093/molbev/msj024)) laid out the general approa...

Background: The present study evaluated purified protein derivative (PPD) changes based on mediastinal lymph node density. Methods: This cross-sectional observational was performed 130 patients who were referred to Valiasr and Amir Al-Momenin Hospitals in Arak, Iran for a CT scan non-infectious non-tumor reasons. gender of the recorded, they then underwent non-contrast CT, their density measure...

In this paper we propose a distributed, mobility transparent broadcast (DMTB) protocol to achieve ef£cient and effective broadcast in mobile ad-hoc networks. The protocol is fully distributed and highly adaptive to node mobility. It does not demand any neighborhood information and incurs little overhead. On one hand, the cross-layer design approach helps achieve effective broadcast with higher ...
