A study of the impact of urban business credit environment on environmental pollution.

Environmental pollution has become a global concern, so it is critical to find out the elements that influence it. Is the urban business credit environment influencing urban environmental conditions? The study takes the entropy method for calculating the environmental pollution index of 276 prefecture-level cities across China from 2010 to 2021, the CE1 index to describe the urban business credit environment, and a spatial Durbin model to empirically analyze the mechanism and transmission path of the urban business credit environment on environmental pollution. The findings demonstrate that: (1) there is an important positive spatial association between China's urban pollution index and urban business credit index, and that the level of spatial clustering of the two is increasing over time.

Neural network-based aeroelastic system identification for predicting flutter of high flexibility wings.

Flutter is an extremely significant academic topic in both aerodynamics and aircraft design. Since flutter can cause multiple types of phenomena including bifurcation, period doubling, and chaos, it becomes one of the most unpredictable instability phenomena. The complexity of modeling aeroelasticity of high flexibility wings will be substantially simplified by investigating the prospect of system identification techniques to forecast flutter velocity.

Emulsifying properties of quinoa protein fibrillar aggregates and their influence on quinoa protein emulsion gel formation.

Fibrillization is a potential approach to improving functionality of seed storage proteins. Herein, the solubility, morphology, wettability, interfacial adsorption and emulsifying properties of quinoa protein fibrillar aggregates were compared with those of quinoa protein isolate (QPI). Effect of fibrillar aggregates on the formation of heat-induced QPI emulsion gels was investigated in the presence 0 or 100 mM NaCl.

Nanoscale Identification of Local Strain Effect on TMD Catalysis.

Strain engineering plays a crucial role in activating the basal plane of the TMD catalysts. However, experimental evidence linking strain strength to activity and distinguishing effects of compressive and tensile strain remains elusive due to the absence of high-resolution correlation techniques. Here, we utilize nanobubble imaging by on-chip total-internal reflection microscopy to visualize active sites on the basal plane of strained MoS during hydrogen evolution reaction and atomic force microscopy to correlatively capture the nanoscale morphology and strain maps.

Methods: Patients unresponsive to traditional medicines for at least 12 months prescribed sacubitril/valsartan from January 2020 to March 2023 were reviewed.

Promoting Charge-Carriers Dynamics by Relaxed Lattice Strain in A-site-Doped Halide Perovskite for Photocatalytic H Evolution.

Because of the unique and superior optoelectronic properties, metal halide perovskites (MHPs) have attracted great interest in photocatalysis. Element doping strategy is adopted to modify perovskite materials to improve their photocatalytic performance. However, the contribution of bare doping-site onto photocatalytic efficiency, and the correlation between doping locations and activity have not yet to be demonstrated.

An electronic patient-reported outcome symptom monitor: the Chinese experience with rapid development of a ready-to-go symptom monitor.

Background: Monitoring symptoms is crucial for the early detection of disease progression and timely intervention, which is essential for reducing severe cases and mortality rates in rapidly spreading pandemics, such as COVID-19. Therefore, during infectious disease pandemics, the rapid development of real-time symptom monitoring platforms is essential. This study aimed to explore the urgent development process of an electronic system for patient-reported outcome monitoring in emergency situations.

Improvement and effectiveness analysis of dynamic/static imbibition experiments.

In low-permeability fractured reservoirs, there is a generalized fluid displacement between the replacement fluid in the fracture and the matrix crude oil. This imbibition behavior plays a crucial role in the development of this type of reservoir. The experimental devices for studying static imbibition behavior are generally susceptible to air pollution on the surface of the test core and a long testing period; the experimental devices for studying dynamic imbibition behavior are generally unable to eliminate the driving action.
