Three‐dimensional reconstruction of loose defects in semi‐rigid base layers using enhanced deep learning and point cloud from GPR images

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 31, Page 6475-6492, 29 December 2025.
Abstract Loose defects in semi‐rigid base layers can critically compromise the structural performance and long‐term serviceability of asphalt pavements. However, accurate identification and quantitative assessment of such defects remain challenging due to the lack of reliable ground‐penetrating radar (GPR) data sets and the limitations of existing ...

A hierarchical framework for three‐dimensional pavement crack detection on point clouds with multi‐scale abnormal region filtering and multimodal interaction fusion

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 31, Page 6577-6596, 29 December 2025.
Abstract Early crack detection enables timely maintenance actions, which in turn help extend pavement life and reduce maintenance costs. Traditional 2D detection lacks detail, while 3D detection faces accuracy and efficiency challenges. This paper proposes a hierarchical crack detection framework—F2CrackDet‐PCD (crack detection based on point cloud ...

Strengthening Dispersive Soils Using Waste Calcium‐Based Composite for Erosion Reduction and Enhanced Lifecycle Performance for Green Subgrade

open access: yesEngineering Reports, Volume 7, Issue 11, November 2025.
A sustainable stabilization approach using 2% Calcium Lignosulphonate (CLS) and 3% Calcium Sulphate (CS) remarkably improves dispersive soil strength, erosion resistance, and durability. UCS increased from 86 to 198 kPa, CBR from 2.3% to 8.4%, with 61%–67% soil loss reduction.

Reversible Cardio‐Renal‐Cerebral Syndrome in a Dog: A Case Report

open access: yesJournal of Veterinary Internal Medicine, Volume 39, Issue 6, November/December 2025.
ABSTRACT A 14‐year‐old miniature Pinscher was presented with azotemia, severe hyperkalemia, and oliguria caused by decompensation of chronic renal disease, along with bradycardia resulting from third‐degree atrioventricular (AV) block. Supportive medical treatment was instituted for the oliguria, azotemia, and hyperkalemia.
