Summary: Two different microstructures of medium Mn steel were obtained through different approaches in hot rolling mill, showing a simultaneous twinning induced plasticity and transformation induced plasticity (TWIP + TRIP) mechanism. However, twinning contributed relatively little to the strength of the alloy, mainly due to the small initial slip lengths that reduced the opportunity for grain work hardening.

Summary: In this paper, a novel box estimation network is proposed for the localization and estimation problems in tracking tasks. The network utilizes a transformer encoder and a transformer decoder to generate fine-grained prior knowledge and captures visual dependencies through local-global self-attention and channel-wise cross-attention. Experimental results demonstrate that the proposed network outperforms existing methods on multiple benchmark datasets, and trackers based on this network achieve competitive performance against state-of-the-art trackers.

Summary: The study investigated the hydrogen embrittlement sensitivity of S690QL structural steel and X80 pipeline steel under different heat treatment conditions, showing differences in hydrogen content, crack formation mechanisms, and microstructures between the two steel grades. Additionally, the results suggest that a controlled bainitic/martensitic microstructure transformation with designed precipitation hardening could enhance strength and suppress hydrogen mobility.

Summary: In the early 20th century, numerous steel structures, especially railway bridges, were built in Europe and are still in use. Fracture mechanics is used to assess the safety of these structures in terms of fatigue failure, along with the stress-life concept. This study aims to experimentally determine fracture mechanics parameters for old mild steel in relation to the stress ratio R, compare the results with literature values, and assess different models based on simulated crack growth calculations.

Summary: This study determined the content and density of adsorbed water in fine-grained soil, and found that adsorbed water plays a significant role in maintaining the compressibility of fine-grained soil and is stable and difficult to discharge. Predicting settlement of fine-grained soil embankment using the improved void ratio of soil parameter was found to be more accurate compared to conventional methods.

Summary: Intelligent thought is associated with fine-grained connectivity patterns in the brain, with predictions based on these patterns being significantly stronger than predictions based on coarse-grained patterns. Previous research overlooked fine-grained architecture due to the inability to resolve idiosyncratic topographies.

Summary: The paper introduces research on fine-grained facial expression recognition in the wild, establishes a new benchmark FG-Emotions, and extends the expression categories to thirty-three classes. The MSAU-Net and TMSAU-Net proposed for facial expression recognition outperform existing solutions on multiple datasets, serving as a strong baseline for future research.

Summary: This paper explores the use of virtual reality in infrastructure management education within civil engineering, utilizing a bridge inspection module in a Cave Automatic Virtual Environment (CAVE) system. The study showed that students demonstrated improved concentration in VR environments and found the experience to be engaging and comfortable. Further exposure to and practice with VR can enhance students' learning experience, although limitations exist for capturing real-world damages in structures.

Summary: In this study, the hydrothermal alteration of perlite into zeolites was investigated for water treatment and softening applications. Different types of zeolites were successfully synthesized from perlite powder, and their performance for metal ion removal and water softening was evaluated. The LTA-zeolite derived from perlite exhibited excellent removal capacity and can be applied effectively for water treatment and softening.

Summary: Digital Twins are predicted to be used by two-thirds of large industrial companies in the next decade, but their actual application in the Architecture, Engineering and Construction (AEC) sector is still at the prototype stage. It is crucial to establish common procedures and standards tailored to the AEC sector in order to make Digital Twins a practice in this industry.

Summary: A single-shot fine-grained object detector was proposed and applied to coal-gangue images in a coal preparation plant. By utilizing grouped convolution, feature fusion, and feature separation modules, the detector demonstrated an average increase of approximately 10% in AP (iou=0.5) compared to other classical detectors when tested on the coal-gangue dataset.

Summary: The close relationship between civil protection organizations and the scientific community is widely recognized as crucial for the effective application of research products in disaster risk management. In Italy, the civil protection has relied on the contributions of the scientific community for about 40 years, particularly in activities related to the entire disaster risk cycle. This paper describes the operation of Competence Centers in Italy, focusing on scientific activities and products related to earthquake and structural engineering science.
