Summary: This work investigates the negative corona discharge generated from wire particles in air insulation. It examines the effect of particle geometries on discharge characteristics and finds that particle length and diameter both influence the discharge current, pulse magnitude, frequency, and fluctuation. A simulation model based on the Finite Element Method (FEM) explains these behaviors and identifies the relationship between pulse repetition rate and electric field distribution, and between pulse magnitude and ionization rate and positive ions velocity.

Summary: Many studies have focused on online shopping adoption in developed countries, but the influence of spatial attributes in emerging economies like China remains unclear. China, as the largest e-commerce market, shows a distinctive geographical pattern of e-shopping usage. The digital divide of e-shopping in China is evident, with urbanized areas having higher online shopping levels. Key drivers of e-shopping adoption in China include urbanization rate, local delivery systems, and internet connection, highlighting the importance of geographical attributes in improving online shopping adoption.

Summary: This study reveals a complex metabolic network involving six redox enzymes that leads to AVM formation, characterized using in vivo gene deletions, in vitro biochemical assays, and one-pot enzymatic total synthesis. Key findings include an FAD-dependent monooxygenase catalyzing oxygen insertion into an amide bond to form the TDO ring in AVM, and the essential role of the TDO ring in AVM's antimicrobial activity.

Summary: Tighter integration of modeling frameworks for climate and air quality is urgently needed to evaluate the impacts of clean air policies on future Arctic and global climate. A study combined a new model emulator and comprehensive emissions scenarios to assess the co-benefits of emissions reductions on climate and human health. The findings suggest that reductions in sulfur emissions, while beneficial for human health, could offset the climate benefits of greenhouse gas reductions by enhancing Arctic warming.

Summary: This study discusses the interactions between impurities and a surrounding ultra-cold Bose gas, and explores the conditions for the formation of bipolaron pairs. It also points out the limitations of the standard methods based on linearizing the condensate field under certain conditions, and proposes a method to remedy these limitations by using the Born-Oppenheimer approximation.

Summary: In this study, a PDMS-based TENG with ZnSnO3 (ZTO) nanostructure on surface-modified carbon nanotubes (SMCs) was prepared, showing high power density suitable for practical applications in energy harvesting and self-power systems. The TENG with 0.3 wt% ZTO-SMC exhibited significantly improved output voltage and current density compared to a pristine PDMS-based TENG. The enhanced performance was attributed to the synergetic effect of enhanced dielectric constant, press-induced polarization, and effective frictional area. This work provides scientific and technical understanding for the development of polymer-based TENGs with enhanced triboelectric performance for energy harvesting and self-powered systems.

Summary: The formation of gas hydrates in gas transmission pipelines is a critical issue in the petroleum industry, and inhibitors have been proven to be an effective method to intercept hydrate formation. By experimentally measuring the CIR, SGR, and RFR, it was found that PVCap has a stronger inhibition impact compared to PVP.

Summary: The double-stranded multifunctional RNA-binding protein Staufen was initially discovered in insects and later found in mammals with two human orthologues. STAU1, one of the human orthologues, plays a key role in RNA metabolism, cell functions, and has implications in cancer development. Studies have shown its potential as a biomarker and therapeutic target for cancer diagnosis and treatment.

Summary: Iron is essential for all organisms and contributes to the virulence of plant pathogenic fungi. Two genes, ClFTR1 and ClNPS6, were identified in the maize pathogen Curvularia lunata, with significant roles in siderophore biosynthesis, oxidative stress mediation, and various stages of fungal development and infection. ClFTR1 regulates conidial germination and appressoria formation in the biotrophic phase, while ClNPS6 regulates toxin biosynthesis and enzyme activity in the necrotrophic phase, indicating their importance as key virulence factors in the pathogen.

Summary: This study investigates the aging characteristics of chromium in soil and its quantitative relationship with soil properties. The results show that with the extension of aging time, the toxicity of chromium decreases and can be well explained by soil organic carbon, clay, and cation exchange capacity.

Summary: This paper investigates the origin and hydrocarbon generation and expulsion histories of the Shaximiao Formation in the Western Sichuan Basin using geochemical parameters and basin modeling technology. The findings reveal that the natural gas within the Shaximiao Formation is a thermogenic coal-type gas primarily sourced from the coal-measure source rock of the Xujiahe 5 Formation. The gas reservoir exhibits high maturity and has the potential to form large-medium and extralarge gas fields. The research findings provide a scientific foundation for the exploration and deployment of natural gas resources in the area.

Summary: Ecological restoration of wetland plants has become a sustainable method for treating effluent wastewater. Root iron plaque in constructed wetlands plays an important role in pollutant migration and transformation. However, the dynamic formation of root iron plaque and its function have not been fully studied, especially in substrate-enhanced wetlands.

Summary: Colored cotton, also known as eco-cotton, has natural color fibers but inferior yield and quality compared to white cotton. The regulatory genes involved in fiber quality and pigment synthesis in colored cotton are not well understood. This study investigated transcriptomic and proteomic changes during fiber development in brown and white cotton cultivars. The study identified differentially expressed proteins and genes, enrichment of specific metabolic pathways, and key genes that can be targeted for improving fiber quality and pigment deposition balance in brown cotton fibers.
