Accreted versus In Situ Milky Way Globular Clusters [PDF]

, 2010
Here we examine the Milky Way's GC system to estimate the fraction of accreted versus in situ formed GCs. We first assemble a high quality database of ages and metallicities for 93 Milky Way GCs from literature deep colour-magnitude data.

Density‐dependent habitat selection in plains bison

The Journal of Wildlife Management, EarlyView.
Using GPS collar data, we tested whether habitat selection of plains bison in Grasslands National Park, Canada, was density dependent. Bison selected for areas of high vegetation productivity far from human activity when population density was low and increased use of lower productivity habitat closer to disturbance as density increased.

Angular Insertion Depth for Cochlear Implantation: A Comparative Analysis on Precision of CT, MRI, and x‐Ray

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Personalized medicine in cochlear implantation has advanced significantly with the advent of software tools that allow for detailed analysis of cochlear anatomy. This facilitates the selection of electrode arrays tailored to the individual cochlear duct length (CDL) and supports anatomy‐based fitting strategies. Concurrently, various
