Summary: With the rapid economic growth in China, improving energy efficiency has become crucial due to the constraints of energy issues on economic development and the environment. This study focuses on the Pearl River Delta region, where high energy consumption and pollution emissions pose challenges. The analysis reveals that, except for Guangzhou and Shenzhen, all regions in the Pearl River Delta show obvious energy inefficiency. Based on the findings, this study provides relevant suggestions for energy reform in the region.

Summary: The research on eco-efficiency in Chinese forest parks over the last decade showed improvements, but significant differences in eco-efficiency among provinces and regions persist. Economically developed regions were mainly driven by pure technical efficiency, while economically underdeveloped regions were mainly driven by scale efficiency. There is a tendency for high and low-value agglomeration in eco-efficiency, with a noticeable Matthew effect.

Summary: This study utilized a standard metafrontier model to evaluate the efficiency of customs offices in Mexico. The findings revealed that border customs offices had the highest within-group variations, whereas internal customs offices maintained constant efficiency and maritime customs offices were closest to the metafrontier. Additionally, border customs offices were the most productive group during the study period, although they were distant from the metafrontier. This research contributes to the existing literature on customs efficiency measurement.

Summary: The research evaluates the eco-efficiency of the Yangtze River Delta Urban Agglomeration (YRDUA) and finds that it has not reached the effective level with variations across different regions. The study identifies severe resource redundancy and negative correlation with eco-efficiency, with environmental pollution being the primary cause for efficiency loss. Technological progress drives regional total factor productivity (TFP), but technical efficiency still needs improvement.

Summary: This paper analyzes the energy efficiency of 23 cities by evaluating Total Factor Energy Efficiency (TFEE). The results show significant differences in TFEE changes among regions, with cities like Harbin, Shanghai, and Changsha showing an upward trend while Chengdu, Chongqing, and others have minor changes. Inadequate resource allocation and lack of technological innovation are the main reasons for the decline in Total Factor Productivity (TFP).

Summary: In the context of industrialized green reform, the well-being of people and sustainable development take precedence over mere economic growth. Decision-makers in the government need to prioritize adjusting people's livelihoods according to the green economy and ecological environment. This study developed a comprehensive livelihood well-being index and incorporated it into an eco-efficiency assessment system using data from 31 Chinese provinces. The results showed significant improvements in the western region, underutilized technology in China, and inter-regional variances as the main drivers of spatial differences in eco-efficiency.

Summary: This study explored the connection between cumulative blood pressure from early adulthood to middle age and right ventricular structure and function in middle age. The findings revealed that higher cumulative systolic blood pressure was independently associated with lower right ventricular function and higher pulmonary arterial pressure. Higher cumulative diastolic blood pressure was independently associated with smaller right ventricular size. These findings suggest that cumulative exposure to increased blood pressure in early adulthood may impact right ventricular health later in life.

Summary: We have investigated the spin-polarized transport properties of a 1,3,5-triphenylverdazyl (TPV) radical-based molecular device with different linkage modes using first-principles transport calculations. It is shown that modulation of the linkage mode can be used to achieve highly spin-polarized current. Our findings are important for the development of high-performance molecular spintronic devices.

Summary: The global oceans serve as terminal sinks or secondary sources for the diffusion emission of pesticides into the atmosphere. However, information on occurrence patterns and air-seawater exchange of pesticides in remote regions like the Southern Ocean is limited. A large-scale ship-based sampling campaign was conducted to fill this information gap, and the results showed low and evenly distributed pesticide concentrations in the Southern Ocean.

Summary: This article presents a strategy to develop highly durable proton exchange membranes (PEMs) for proton exchange membrane fuel cells (PEMFCs) by intercalating double-layer expanded polytetrafluoroethylene (ePTFE) skeletons and doping CeO2 radical scavengers into perfluorosulfonic acid (PFSA) membranes. The results show that the developed membranes have significantly improved mechanical properties, lower swelling rates, and superior dimensional stability compared to conventional single-layer ePTFE reinforced membranes. They also exhibit better chemical durability behaviors and lower hydrogen crossover increase, reduced power performance attenuation, and smaller membrane impedance increase. The CeO2-doped membranes further enhance chemical durability during the open-circuit voltage durability test. Overall, the developed membranes are promising candidates for advanced PEMs with high mechanical and chemical durability for PEMFC applications.

Summary: This paper proposes an iterative photon counting nonorthogonal multiple access-multiple-input-multiple-output (NOMA-MIMO) system based on optical intelligent reflecting surface (IRS). The channel fading coefficient matrix of the NOMA-MIMO system is constructed by analyzing the geometric and misalignment losses under turbulence effect in the optical IRS-based atmospheric channel. A novel iterative parallel interference cancellation algorithm based on logarithmic likelihood ratio is developed for signal detection at the receiver. The reliability of the proposed system is proved through simulation of bit error rate (BER), with a BER performance of 2 x 10-5 at -165 dBJ per bit for the scenario of 3x5 MIMO system. Additionally, the numerical results indicate that the proposed system has a rapid convergence performance in the external information transfer process.

Summary: In this study, a light activation strategy was demonstrated to regulate the dynamic restructuring of Cu active sites in a TiO2-supported Cu catalyst during low-temperature methanol steam reforming. The thermally deactivated Cu/TiO2 underwent structural restoration from Cu2O to metallic Cu under illumination, leading to significantly enhanced activity and stability. The optimized Cu/TiO2 exhibited a high H-2 production rate under low-intensity solar irradiation, outperforming conventional photocatalytic and thermocatalytic processes. The results suggest the feasibility of real-time functionalization of catalysts through the strong light-matter-reactant interaction.
