Solving the Boltzmann Equation on GPU

open access: yes, 2010
We show how to accelerate the direct solution of the Boltzmann equation using Graphics Processing Units (GPUs). In order to fully exploit the computational power of the GPU, we choose a method of solution which combines a finite difference discretization

Evolution of research on global amphibian declines

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

Global review of shorebird tracking data to identify research gaps and conservation priorities

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Tracking has enabled rapid advances in knowledge of the movement behavior and habitat use of shorebirds and is thus making a growing contribution to their conservation. However, realizing the full potential that tracking holds for conservation involves understanding what has been performed on shorebirds to date and identifying regional and ...

APOE ɛ4 carriership determines a faster plasma p‐tau217 progression in Aβ‐positive individuals

open access: yesAlzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract INTRODUCTION It is unclear whether the different Alzheimer's disease (AD) progression trajectories of apolipoprotein E (APOE) ɛ4 carriers is reflected by blood phosphorylated tau (p‐tau) analytes. METHODS We assessed longitudinal trajectories in plasma p‐tau181, 217, and 231, in amyloid beta–positive (A+) and negative (A−) APOE ɛ4 carriers (E+)
