The study investigates the therapeutic effects of the AR/PCC herb pair on diabetes-related osteoporosis (DOP) in a rat model. The AR/PCC herb pair, derived from Traditional Chinese Medicine, was found to reduce fasting blood glucose levels, improve bone loss, and enhance osteogenic capacity in diabetic rats. The research highlights the herb pair's ability to inhibit osteoblast pyroptosis and promote nerve ingrowth and angiogenesis through the activation of the Nrf2/Keap1 signaling pathway. These findings suggest that AR/PCC could be a promising therapeutic agent for DOP treatment, offering a potential alternative to current therapies with fewer side effects.

The study explores the mental health of frontline Chinese healthcare workers during the COVID-19 pandemic by analyzing their dream experiences. Through semi-structured interviews, six themes were identified: warning, escape, alienation, gender inequality, archetypal-mythological dreams, and negative emotions. The research highlights the connection between healthcare workers' mental health and their dreams, offering insights for better psychological support during global health crises.

The article discusses the development of a poly(L-histidine)-based multifunctional nanoplatform designed for stimuli-responsive release and efficient siRNA delivery in non-small cell lung cancer. The research highlights the potential of this nanoplatform in enhancing the delivery and effectiveness of siRNA, which could lead to improved therapeutic outcomes for patients with this type of cancer.

A prospective cohort study on longitudinal data from Wuhan, China, utilized multimodal deep learning to predict long-term SARS-CoV-2 neutralizing antibody levels. The study included patients admitted to Tongji Hospital from February to April 2020, with follow-up visits up to 18 months post-discharge. The research found that IgG levels peaked at 3 months and remained stable until 12 months, then declined by 18 months. Critical patients showed higher IgG levels, suggesting more robust immune memory. A novel deep learning model was developed to predict long-term antibody levels using demographic characteristics, medical history, inspection reports, and CT scans. The model demonstrated high accuracy and could be used to inform vaccination strategies and save public health resources.

The study investigates the drag force exerted on cylindrical intruders with different nose shapes as they penetrate a granular medium, using both experiments and discrete element method (DEM) simulations. It finds that the drag force varies with the nose shape, penetration velocity, intruder diameter, and friction coefficient. The research identifies two piecewise functions for average drag force versus penetration velocity and scaled drag force versus friction coefficient. The study concludes that the drag force is proportional to the square of the intruder diameter and remains constant when the friction coefficient exceeds 0.9. The findings provide insights into the interaction dynamics between intruders and granular media, with implications for engineering applications.

The study evaluates the cultural tourism development potential (CTDP) in the middle and lower reaches of the Yellow River, using systems theory and sustainable development theory. It employs methods like entropy, multi-index comprehensive evaluation, spatial kernel density estimation, and centroid transferring model to analyze the temporal and spatial evolution of CTDP across 43 cities. The findings reveal significant spatial differences and regional dependencies in CTDP, with Xi'an, Zhengzhou, and Qingdao identified as high-potential areas. The study underscores the importance of technological innovation, environmental support, and regional cooperation for sustainable cultural tourism development.

The study investigates the hematite flocculation–bubble mineralization process using high-speed dynamic cameras to optimize the flotation process. It finds that larger flocculant sizes lead to shorter sliding times and more stable adhesion on bubble surfaces, with specific conditions favoring efficient mineralization. The research highlights the importance of floc and bubble sizes in improving flotation sorting efficiency, providing a scientific basis for enhancing the process.

The study investigates the spatiotemporal patterns of urban expansion in the Yangtze River Delta Urban Agglomeration (YRDUA) from 2000 to 2020 using nighttime light data and MODIS NDVI. Utilizing the support vector machine method, the research extracts urban clusters and analyzes the intensity and inequality of urban growth. The findings reveal a rapid urbanization pace during the 10th five-year plan, a slight decline in the 11th, and steady growth in the 12th and 13th plans. The study identifies GDP, total fixed asset investment, tertiary industry, gross industrial output, urban area, and urban permanent residents as primary factors influencing urban intensity. The results provide significant insights for sustainable urban development in the YRDUA region.

Dynamic vibration absorbers (DVAs) are essential in engineering for vibration control. This study focuses on optimizing a viscoelastic Maxwell-type DVA with an inerter and negative stiffness spring using a combination of traditional theory and the particle swarm optimization (PSO) algorithm. The research demonstrates that the PSO algorithm can effectively adjust system parameters to minimize maximum amplitude, achieving better control performance compared to traditional methods. The study validates the optimized parameters through numerical simulations and comparisons with typical DVAs, showing superior vibration control. The findings provide a theoretical and computational basis for future DVA optimization and design.

The study focuses on improving the computational efficiency of discrete element simulations for fine-grained iron tailings by using an enlarged particle model calibrated with the Hertz-Mindlin with JKR contact model.

The findings provide a reference for using EDEM software in simulating fine-grained iron tailings, ensuring accurate and efficient numerical simulations.

The study investigates coagulation, fibrinolysis, and endothelial biomarkers in cirrhotic patients, focusing on those with or without portal vein thrombosis (PVT). Conducted in Beijing hospitals, the research involved 175 cirrhotic patients and 50 healthy individuals. Key findings indicate that TAT, TAT/t-PAIC, FⅧ: c, and vWF: Ag can serve as potential biomarkers for predicting PVT. The study highlights the complex hemostatic disorders in cirrhotic patients, emphasizing the need for reliable biomarkers for early detection and management of PVT. The research underscores the limitations of traditional coagulation tests in assessing thrombotic risk in cirrhosis.
