Summary: The rise of high-speed railway increases the probability of serious derailment accidents during earthquakes. A 2.5D finite element model was used to study the ground vibration under combined seismic and high-speed train loads. Numerical examples demonstrate the effectiveness of the proposed method in estimating ground vibration caused by high-speed train load during earthquakes. The coupling effect of seismic and high-speed train loads amplifies the low-frequency components of ground vibration, while the moving train load dominates the medium-high frequency contents. The critical train speed increases with the increase of ground stiffness and earthquake motion intensity.

Summary: Precast segmental construction of concrete bridge decks is popular due to its short construction time and low cost. However, the segment-to-segment joints may become weak parts of the superstructure during earthquakes, especially due to the lack of continuous rebar. This research investigates the effects of the vertical component of earthquakes on the joints of precast segmental bridges. The results show that the vertical component can significantly affect the behavior of the joints, leading to potential failure.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
