While CC is widely used for drainage and slope protection, its behavior under railway-specific dynamic forces remains insufficiently studied. Addressing this gap, full-scale laboratory tests, including advanced GOM ATOS 3D scanning and four-point bending evaluations, were conducted to assess deformation, settlement, and shear resistance. Results showed that CC integration reduced settlement by 44.9% compared to unreinforced tracks after one million load cycles, while inner shear resistance can be improved by up to 52-57%. CC's quasi-rigid nature allowed it to withstand over 2.3 million dynamic load cycles – equivalent to 25.875 million tons of mixed traffic – without significant cracking or material failure. The material maintained structural cohesion, with microfractures contributing to its enhanced durability and resistance to deformation. Bending tests revealed that fiber reinforcement in the case of longitudinal weaving direction increased flexural strength by 55.1% after 7 days and 81.7% after 28 days of curing, further emphasizing CC's robustness. These results highlight CC's ability to address issues such as weak subgrades and poor drainage, making it a promising solution for localized track repairs and challenging operational environments. Future research should explore long-term field performance, extreme environmental conditions, and advanced modeling techniques to optimize CC applications in railway infrastructure.

The case study examines the historical Csíky Gergely Theater in Kaposvár, Hungary, built in 1911. At that time, the design methodology and construction process were carried out using a relatively rudimentary standard framework. This study demonstrates that a multi‐phase assessment procedure integrating numerical analysis and primarily non‐destructive testing techniques can significantly reduce structural analysis uncertainty. This approach allows for an optimal selection of the reliability index ( β target ), even when deviating from design standards. Based on this modified reliability index and considering the diagnostic and material test results, the partial factors used for the assessment can be optimally adjusted, and in most cases reduced, compared to those in design codes for new structures. Consequently, the extent of structural interventions needed to increase the load‐bearing capacity can be minimized.

The fuzzy signature model was constructed to describe a masonry based on different measurements of. The aggregations of the signature were given as weighted geometric means. Weights of the input values of the aggregations were determined by two different optimization methods: (i) an iteration procedure was chosen, which showed significant differences in the result; (ii) a genetic algorithm was used, which produced similar but more accurate approximations to the results of the destructive tests. The comparison of the two optimization results gave new conclusions that are valuable information for the further development.

Implementing precise and scientifically rigorous acoustic modifications is crucial for these classrooms. Calculations and simulations based on Sabine's equation or acoustic modeling software require precise absorption coefficients of the finishing materials, making it challenging to determine the required sound absorption increment. This paper proposes a method of equivalent substitution measurement: A non-destructive control group is established for acoustic experimentation, allowing for the precise calculation of the sound absorption increment required to achieve the target reverberation time. This approach provides scientific, rigorous, and customized reverberation time recommendations particularly for complexly shaped spaces from small to medium size to optimize the acoustic environment.

During this phase, urban renewal must adapt to the new objectives and demands of urban development in the new era. The concept of “Inside Flow”, with its environmental and social friendly characteristics, provides a universally applicable and effective means for the sustainable renewal of old communities. Drawing on the practical case study of the renewal of the eastern section of Yaojiayuan Road in Beijing, a “small-scale, gradual, and recyclable” strategy based on the concept of “Inside Flow”, is operated for the renewal of public space in old communities that aligns with spatial form development and urban operational logic. This paper aims to offer insights for the sustainable renewal of public space in old communities in the future.

This study focuses on commercially available copper‐ and bronze‐filled polylactic‐acid (PLA) composites printed with FFF technology and on providing guidance for future practical applications, particularly in the biomedical field and 4D printing. In this research, static and dynamic mechanical tests, scanning electron microscopic imaging, and electric resistance measurements were conducted, and the thermal properties were determined by thermal conductivity measurements and differential scanning calorimetry, and thermogravimetric analysis (DSC‐TGA). Cytotoxicity was assessed using an A549 cell viability assay. The results show that the material's brittleness increases in proportion to the volume percentage of metal particles; among the copper composites FormFutura MetalFil – Classic copper (29.14 vol.%) had the lower tensile strength (15.4 MPa ± 0.17 MPa), while for bronze composites, the tensile strength was lower for ColorFabb BronzeFill (33.64 vol.%, 17.7 MPa ± 0.54 MPa). Furthermore, these composites have no cytotoxic effect in short‐term contact, and their enhanced thermal conductivity over traditional prosthetic materials makes them promising candidates for the development of prostheses intended to mitigate thermal discomfort.

However, post-transformation assessments of the built environment often receive less attention. This study examines the Jingzhou Yang Pier area in China, now a cultural and creative industrial park formerly a waterfront industrial heritage site. Through questionnaires and field survey, an innovative evaluation index system is developed for these spaces, analyzing user satisfaction via the Analytic Hierarchy Process. Findings highlight insufficient industrial historical and cultural characteristics and a lack of cultural identity post-transformation in the Yang Pier area, offering a reference for ongoing quality improvement and sustainable development of similar urban waterfront heritage projects.

The tests were performed by conventional electrochemical methods. Open circuit potential, time measurements were used to measure the corrosion potential values and its change in time during exposition to corroding media. Cyclic potentio-dynamic polarization curves were used to investigate the susceptibility to pitting corrosion. Significant differences could be detected between the corrosion behavior of the alloy of same composition prepared with conventional technology and with cold metal transfer one. The investigations clearly indicate different stages of sensitization and susceptibility to pitting corrosion.

Windows serve not only for ventilation and lighting but also as design elements, reflecting cultural significance through various shapes and forms. In gardens, windows frame and borrow external views, blending nature with the interior space. This concept enhances the harmony of traditional Chinese garden design. This paper examines the integration of traditional window design with modern approaches, as seen in the renovation of the Beihai Garden Expo Park's “Ancient and Modern, Chinese and Foreign” campus.
