The results indicate that, at the macroscopic level, with increasing duration of coupled heat and moisture exposure, the failure mode of the masonry specimens transitions from ductile to brittle behavior. The compressive strength and elastic modulus initially increase and subsequently decrease. At the mesoscopic scale, ancient bricks exhibit minimal response to the wet–hot environment, with a gradual increase in porosity, whereas medium- and large-sized pores in the mortar are significantly affected, leading to a non-linear variation in porosity—first decreasing and then increasing. At the microscopic level, limited crack propagation is observed in the ancient bricks, while pore expansion and crack interconnection occur extensively in the mortar, forming a complex pore-crack network. During the coupled heat and moisture process, variations in moisture and temperature initiate microstructural damage, which further induces mesoscopic cracking and ultimately leads to a significant deterioration in the overall mechanical performance. This study provides valuable insights into the mechanical behavior and progressive damage evolution of ancient masonry structures in hot and humid environments.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"490 ","pages":"Article 142453"},"PeriodicalIF":7.4,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144513780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to exploit the crystalline water in phosphogypsum to develop a novel warm-mix asphalt additive, thereby achieving high-value utilization and addressing the variability in the performance as a warm-mix additive. Initially, the atmospheric acidification method was employed to synthesize a phosphogypsum warm-mix additive (PWMA) with high purity and minimal impurities. Subsequently, the PWMA was characterized through X-ray diffraction (XRD), X-ray fluorescence spectroscopy (XRF), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TG). Finally, the laboratory-prepared WMA mixture containing PWMA and traditional hot-mix asphalt (HMA) mixture underwent comprehensive engineering performance tests, including moisture susceptibility test, wheel-tracking test, beam bending test, and four-point bending test. The experimental results demonstrated that the atmospheric acidification method effectively reduced the impurity content in phosphogypsum, yielding a PWMA with calcium sulfate dihydrate purity exceeding 99 %. The infrared absorption peaks at 3390 cm⁻¹ and 1620 cm⁻¹ correspond to hydroxyl (O-H) vibrations, indicating the presence of crystalline water molecules in PWMA and confirming its water-releasing capability. The PWMA exhibited its initial weight loss stage between 50–100 ℃, with a 0.29 % mass loss, attributed to the adsorption of atmospheric moisture containing free water molecules. The second weight loss stage commenced at 100 ℃, with a 20.7 % mass loss at 150 ℃, attributed to crystalline water release. PWMA-added WMA mixtures demonstrated overall superior performance compared to HMA, with slightly reduced low-temperature and water stability, yet remaining comparable and satisfactory. This study confirms the viability of phosphogypsum as an effective and sustainable WMA additive.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"490 ","pages":"Article 142326"},"PeriodicalIF":7.4,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144513783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, accurately recognizing human actions in these environments presents challenges due to complex spatial–temporal dependencies and dynamic joint relationships. Graph Convolution Networks (GCNs) are utilized widely for action recognition, but they have poor accuracy for modeling long-range node correlations. Also, current GCNs have limitations in extracting various features due to utilizing the same pattern extraction for all frames. To overcome these issues, this study presents a novel approach to skeleton-based action recognition for manufacturing tasks using a Dual-Attention Graph Convolution Network (DAGCN). The proposed model integrates a Parallel Attention-Graph Mixer (PAGM) and Temporal–Spatial Attention Integrator (TSAI), enhancing the capture of both global and local joint relations and addressing the dynamic nature of skeletal joint relationships. Extensive evaluations on benchmark datasets, including HA4M that specifically designed for assembly tasks, NTU RGB+D, Northwestern-UCLA, and NTU RGB+D120, reveal the superior performance of DAGCN over state-of-the-art methods in terms of accuracy and computational efficiency. Experimental results demonstrate that DAGCN outperforms state-of-the-art methods, achieving a Top-1 accuracy of 89.0% on the HA4M dataset. The results validate DAGCN’s effectiveness in recognizing fine-grained human actions in industrial settings, contributing to improved efficiency and safety in human–robot collaboration.

Achieving sustainability of HRC, encompassing economic, environmental, and social dimensions, remains challenging to ensure safety, efficiency, and adaptability. Human Motion Prediction (HMP) can address these challenges by enabling robots to anticipate human actions and respond proactively. However, existing HMP studies often neglect to incorporate contextual and interaction-based information. The practical applicability of HMP in industrial settings requires further demonstration. Therefore, this study aims to apply context- and interaction-aware HMP to enhance sustainability of HRC in I5.0. A motion capture system collects human motion data, while a camera tracks object position as contextual information. Human-Object Interaction (HOI) is identified for HMP. A transformer model is applied for HMP based on integrated context and interaction data. Additionally, the applicability of HMP in industrial settings is demonstrated by a power transformer assembly. Two additional cases are applied for validation. Results show that object recognition achieved 98 % accuracy. The identified interaction periods are effective in enhancing HMP performance. HMP with context and interaction data achieves an Average Displacement Error (ADE) of 0.07 m and a Final Displacement Error (FDE) of 0.10 m. The demonstration results suggest that the HMP enabled proactive robot control, contributing to safer, more efficient, and adaptive production.

Field survey data were used for model calibration, providing the foundation for the analysis. The performance of four 4-Dimensional Variational Assimilation algorithms (4DVAs)—Particle Swarm Optimization (PSO), Simulated Annealing (SA), Shuffled Complex Evolution-University of Arizona (SCE-UA), and Gray Wolf Optimization (GWO)—was compared with four sequential DA algorithms (SDAs)—Ensemble Kalman Filter (EnKF), Ensemble Variational (EnVar), Ensemble Square Root Filter (EnSRF), and Particle Filter (PF). The 4DVAs were developed by integrating constraint DA Algorithms (CDAs) into the 4D-Var framework, enhancing their capability to optimize model states over a time window. Additionally, the performance of their coupled DA algorithms was evaluated. The results indicated that the coupled of SA and PF (SA-PF) achieved the best performance in terms of model accuracy.

Although Latin America contributed relatively little to global energy-related CO₂ emissions and maintains a predominantly renewable electricity mix, it remains the largest emitter in the world from land use change and forestry sectors. The region's continued dependence on fossil fuels, particularly in high-emission sectors such as transport, as well as, its reliance on oil revenues and extractive industries presents significant structural barriers. Weak, often non-binding, climate governance frameworks further undermine progress.
