Undesirable Effects of Biogenic Emissions From Urban Green Spaces on Air Quality Are Counteracted by Their Transpiration and Dry Deposition

Earth's Future, Volume 13, Issue 12, December 2025.
Abstract Urban green spaces (UGSs) are recognized beneficial for thermal comfort, yet its potential effects on air quality due to biogenic volatile organic compounds (BVOCs) emissions have received concerns. UGSs affect air quality through multiple pathways, some of which were generally missing in existing literature. Here we assess the impacts of UGSs

Progressive development of cracks in biochar–cement composites through multiscale analysis

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 30, Page 5952-5971, 19 December 2025.
Abstract The intrinsic brittleness of the cement matrix limits its synergy with steel reinforcement bars, constraining energy dissipation and crack control capacity of concrete. Enhancing the ductility of cementitious materials is, therefore, essential for improving structural resilience.

From pixels to rating—A semiautomated system linking multi‐damage segmentation and condition rating in concrete bridge inspections

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 30, Page 5842-5866, 19 December 2025.
Abstract While machine learning (ML) has advanced image‐based damage detection, a critical gap remains: the automated translation of detected damage into standardized condition ratings used in structural assessments. Most existing approaches stop at semantic segmentation, overlooking the damage rating step essential for practical inspections.
