Flexural behavior and bearing capacity calculation of prestressed composite box girders with corrugated high-strength webs and UHPC slabs

To enhance the spanning capacity and crack resistance of composite box girders with corrugated webs, a novel composite box girder featuring corrugated high-strength steel webs and UHPC slabs was proposed prestressed with both internal and external tendons. To investigate the flex...

Analysis of construction response for mechanized construction of metro connecting passages

To investigate the influence of mechanized pipe jacking construction for connecting passages in weathered granite strata on the settlement and deformation of left and right shield sections of metro tunnels and ground surface, this paper takes the pipe jacking project of No.1 conn...

An improved MADDPG-based framework for bidirectional safety management of construction robot interaction

Purpose Safety risks are particularly pronounced when multiple construction robots collaborate in complex construction environments. To enhance collaborative efficiency while ensuring operational safety, this study develops and evaluates, in a scaled simulation, a bidirectional s...

Three-Dimensional gelatinous Network-Tailored magnetic Fe3O4@Ag6Si2O7 heterostructures for efficient Visible-Light-Driven water remediation

Severe agglomeration of spherical magnetic photocatalysts can restrict accessible surface area and catalyst recovery. Here, a tailored sol–gel protocol followed by interfacial thiolation was used to construct a three-dimensional gelatinous Fe 3 O 4 @Ag 6 Si 2 O 7 heterostructure...

Facial dermal exposure-related parameters and skincare behaviors among adult women from six cities in China

The face is a primary site of exposure to skincare products, cosmetics, and sunlight. However, population-specific data on facial dimensions and product use among adult women in China remain limited. Current dermal exposure assessments often rely on default parameters derived fro...

Characterizing the Interaction Mechanism between Asphalt and Mineral Filler in Asphalt Mastics of Mastic Asphalt Concrete Using Rheological Analysis, Hirsch Model, and 3D DEM

Abstract Asphalt binder and mineral filler are key components that significantly affect the properties of mastic asphalt (MA) mixtures. Asphalt mastic, formed by mixing mineral filler and asphalt binder, offers an effective way to study their roles within the MA system. This stud...

A surrogate modeling approach for rapid moving-load prediction of steel box girder bridges within a unified COMSOL framework

Different software platforms may influence the surrogate model’s comparison and evaluation results. To overcome this challenge, this paper develops a unified surrogate modeling framework to predict the structural responses of a steel box girder bridge under moving-load analysis,...

Quantifying the Flexibility of Centralized Hot Water Systems at a University Campus by Considering Demand Response Participation Uncertainty

Centralized hot water systems in university dormitories can provide significant energy flexibility through demand response (DR). Thus far, however, existing studies have mainly focused on system-level optimization and have failed to provide a quantitative framework that accounts...

In-Plane Shear Behavior of Masonry Walls Strengthened with High-Ductility Concrete and Steel Connectors

This study investigates the influence of high-ductility concrete (HDC) strengthening configurations and steel connector positions on the in-plane shear performance of masonry walls in a retrofit scenario where the external masonry facade is retained while the original masonry wal...

How has Shanghai built a sustainable municipal solid waste management system through 30 years of socio-ecological practice?

Municipal waste management, widely recognized as a complex problem involving environmental, social, economic, and governance issues, has long received extensive attention from governments, academia, and the public. Since the late twentieth century, Shanghai has undergone a three-...

The landscape and plasticity of transposable element expression in an adult stem cell of high physiological and clinical significance

Abstract Transposable elements (TEs) contribute to diverse aspects of stem cell biology, particularly in germline and pluripotent stem cells, which typically exhibit more open chromatin. In human adult stem cells (ASCs), however, a comprehensive framework describing the landscape...
