Automatic Extraction of Grasses and Individual Trees in Urban Areas Based on Airborne Hyperspectral and LiDAR Data
This article proposes a three-dimensional (3D) vegetation extraction workflow to extract urban grasses and trees at individual tree level in urban areas using airborne LiDAR and hyperspectral data. Results suggest that two- and three-dimensional urban vegetation extraction could play a significant role in spatial layout optimization and scientific management of urban vegetation.

Effect of pressure quenching on the structures and properties of borosilicate glasses: Insights from molecular dynamics simulations
Article describes how processes including hot compression, cold compression and subsequent annealing on the structures and properties are investigated and compared. They found that applying pressure up to 10 GPa at the glass transition temperature led to permanent densifications and a dramatic increase of elastic moduli by 90%, while thermal annealing reversed the increase and applying pressure at ambient temperature did not increase the modulus.

Documenting Times of Difficulty and Crisis: Case Study of Leveraging an App to Gather University Community Memories
Presentation examining the deployment of The Keeper App, developed at the University of North Texas (UNT) Libraries, to help students document their daily lives as members of the UNT campus community. Deployed one year before the COVID-19 pandemic hit the world, the Keeper App soon became a means for students and other members of the UNT community to share their experiences from isolation during the time of crisis.
