TL;DR: An overview of the IDX file format and how it is generated using PIDX is provided, and a data model description and a novel aggregation strategy to enhance the scalability of the PIDX library are presented.

TL;DR: A progressive Poisson solver is introduced that processes images in a purely coarse-to-fine manner, providing near instantaneous global approximations for interactive display and providing a robust and scalable out-of-core solver that consistently offers high-quality solutions while maintaining strict control over system resources.

TL;DR: The first 3-dimensional images of lung autopsy tissues taken from a COVID-19 patient are presented, including 3D “virtual histology” of cubic-millimeter volumes of the diseased lung, providing unique insights into disease processes contributing to mortality that could inform frontline treatment decisions.

TL;DR: A new approach for the visualization and analysis of the spatial variability of features of interest represented by critical points in ensemble data, based on the new notion of Persistence Map, a measure of the geometrical density in critical points which leverages the robustness to noise of topological persistence to better emphasize salient features.
