Analysis of Injury Severity of Drivers Involved Different Types of Two-Vehicle Crashes Using Random-Parameters Logit Models with Heterogeneity in Means and Variances

This study proposes random-parameters multinomial logit models, with heterogeneity in means and variances, to explore the differences in the factors influencing injury severities of drivers involved in different types of two-vehicle crashes. The models are verified using crash data from the United Kingdom (UK) over three years (2016–2018). Three...

Integrating the flow regime and water quality effects into a niche-based metacommunity dynamics model for river ecosystems

Aquatic community dynamics are closely dominated by flow regime and water quality conditions, which are increasingly threatened by dam regulation, water diversion, and nutrition pollution. However, further understanding of the ecological impacts of flow regime and water quality conditions on aquatic multi-population dynamics has rarely been...

Effects of GBFS content and curing methods on the working performance and microstructure of ternary geopolymers based on high-content steel slag

Aimed to address the low utilization rate of steel slag (SS) and its challenge in resource utilization in China, this study developed ternary geopolymers made by high-content (50%) SS together with fly ash (FA) and granulated blast furnace slag (GBFS). The effects of GBFS content (0–40%) and curing methods (water curing, standard curing,...

Designed Multifunctional Spider Silk Enabled by Genetically Encoded Click Chemistry

Spider silk is recognized for its exceptional mechanical properties and biocompatibility, making it a versatile platform for developing functional materials. In this study, a modular functionalization strategy for recombinant spider silk is presented using SpyTag/SpyCatcher chemistry, a prototype of genetically encoded click chemistry. The...

Anisotropic proximity-induced superconductivity and edge supercurrent in Kagome metal, K_1-xV₃Sb₅

Materials with Kagome nets are of particular importance for their potential combination of strong correlation, exotic magnetism, and electronic topology. KV3Sb5 was discovered to be a layered topological metal with a Kagome net of vanadium. Here, we fabricated Josephson Junctions of K1-xV3Sb5 and induced superconductivity over long junction...

Biosynthesis of cyclic ketones by a H₂O₂ self-sufficient cascade reaction

In the present work we propose a bienzymatic cascade for the oxyfunctionalisation of cycloalkanes to cyclic alcohols/cyclic ketones. By combining a H₂O₂-dependent peroxygenase with a O₂-consuming and H₂O₂-producing alcohol oxidase an overall aerobic oxidation system was established. A...

GlobalMatch: Registration of forest terrestrial point clouds by global matching of relative stem positions

Registering point clouds of forest environments is an essential prerequisite for LiDAR applications in precision forestry. State-of-the-art methods for forest point cloud registration require the extraction of individual tree attributes, and they have an efficiency bottleneck when dealing with point clouds of real-world forests with dense...

Numerical simulation on reflective cracking behavior of asphalt pavement

Cracks are one of the main problems that plague road workers. A correct understanding of the internal crack propagation mechanism of asphalt pavement will help road workers evaluate the road’s working status more comprehensively and make more reasonable decisions in design, construction, and maintenance work. This paper established a three...

Effect of CaO content in raw material on the mineral composition of ferric-rich sulfoaluminate clinker

Ferric-rich calcium sulfoaluminate (FR-CSA) cement is an eco-friendly cement. Fe₂O₃ exists in different minerals of FR-CSA clinker, e.g., Ca₄Al₂Fe₂O₁₀ (C₄AF), Ca₂Fe₂O₅ (C₂F), and Ca₄Al_6-2_xFe...
