Tunnel face extraction method for drill-and-blast tunnels considering occlusion and blur degradation

Reliable extraction of tunnel-face regions is essential for image-based rock-mass interpretation and intelligent construction control in drill-and-blast tunnels. However, field images are often degraded by machinery and worker occlusions, invalid backgrounds, uneven illumination,...

Fibroblast growth factor 21 is linked to ambient temperature-dependent regulation of pathological cardiac hypertrophy in UCP1 knockout mice

Adipocytes play an important role in the regulation of cardiovascular health and disease. However, the molecular mechanisms underlying the endocrine role of brown adipose tissue (BAT) in pathological cardiac remodeling remain unclear. Herein, we show that uncoupling protein 1 (UC...

Prediction of ground vibration induced by high-speed trains over elevated tracks based on machine learning

To address the issue of the complexity and high computational cost of ground vibration prediction models induced by high-speed trains crossing bridges, this study proposes a prediction method based on machine learning. Initially, this research derives a dataset of ground vibratio...

Mechanical Performance of Corrugated Steel−Concrete Composite Structures: An Experimental Study on Arch Bridges

Abstract Corrugated steel arch bridges have been extensively employed in transportation infrastructure owing to their favorable mechanical performance and construction effi Corrugated steel arch bridges are widely used in transportation infrastructure but suffer from stress conce...

Flocculation Characteristics and Dewatering Performance of Bored Pile Waste Slurry with Different Flocculants

Bored pile waste slurry generated during bridge substructure construction exhibits high water content and stable colloidal properties, resulting in difficult solid–liquid separation and severe environmental risks. To improve solid–liquid separation and facilitate efficient dispos...
