Abstract This study aimed to determine and analyze the design loads required for the electrification of a 55‑kW agricultural tractor through field experiments. A measurement system was installed to record data from the engine, driving axles, power take‑off (PTO), and hydraulic pump during plow tillage, rotary tillage, and driving operation in a silt loam paddy field. The study specifically focuse…

Abstract The effectiveness of public health policies has a major impact on society. Throughout the COVID-19 pandemic, policy-makers worldwide introduced various public health measures, such as social distancing and mask-wearing, to address the severe threat posed by the disease. Despite the importance of these issues, there has been no direct, visual evidence that mask-related policies led to the…

Abstract Farmland shelterbelts serve as a crucial ecological barrier for agricultural production operations in ecologically fragile rural areas. Farmers’ participation in the management and protection of these shelterbelts is a key prerequisite for ensuring the sustained and effective realization of their ecological benefits. Based on the social-ecological system framework and interactive determi…

Abstract Using a combination of computational and experimental methods, the corrosion protection effectiveness provided by cyclobenzaprine (CBA) for carbon steel (CS) in a 1.0 M hydrochloric acid solution was systematically examined. The corrosion protection efficiency and electrochemical behavior of CS with and without different concentrations of CBA were assessed using gravimetric measurements,…

Abstract Serpentine and buried air intake configurations are widely employed in modern fighter aircraft, which induces significant swirl distortion at the inlet and adversely affects compressor operational stability. This study investigates the instability mechanism and stability enhancement technology for high-speed axial compressors under paired swirl, employing combined numerical simulation an…

Abstract Colistin is a last-resort antimicrobial in human and veterinary medicine, yet it remains unclear whether prolonged exposure can drive collateral resistance beyond polymyxins. Here, we used a spatial experimental-evolution platform, the Microbial Evolution and Growth Arena (MEGA)-plate, to examine adaptation of Escherichia coli ATCC 25922 to stepwise colistin selection in three independen…

Abstract Providing fresh and clean water to all is the objective of Sustainable Development Goal 6. Consuming clean water improves health for all living beings worldwide. Therefore, accurately estimating the water quality and classifying the type of water (i.e. whether it is used for potable purposes or not) based on physicochemical parameters is considered a challenging issue due to the dynamic …

Abstract Parkinson’s disease (PD) affects physical activity, and physical activity reduces the burden of PD. Although shown in studies using inertial measurement units (IMU), it remains unclear at which position physical activity change can best be detected in this population. Within the FAIRPARK-II trial, a subgroup of 25 newly diagnosed persons with PD (pwPD) not taking disease-specific medicat…

Abstract Aimed at addressing the constraints of farmland soil acidification on soil health and crop productivity in southern Henan Province, this study investigated the comprehensive ameliorative effects of different soil conditioners and identified the optimal amendment strategy. Based on a continuous fixed-point field experiment conducted from 2023 to 2025, treatments including NB (nitrogen fer…
