    Table 5_Research on the dynamic evolution and differential analysis of the development efficiency of China’s marine economic circles.xlsx by Lin Zhang (8926)

    Published 2025
    “…<p>This study focuses on the economic development efficiency of China’s three major marine economic zones, aiming to explore their dynamic evolution rules and regional disparity characteristics, thereby providing theoretical foundations and practical guidance for promoting sustainable marine economic development. Based on panel data from 11 coastal provinces in China (2012-2021), the research employs a three-stage super-efficient slack-based measure (SBM) model with undesirable outputs to measure marine economic development efficiency Additionally, it uses Dagum Gini coefficient decomposition method to systematically investigate regional disparities and their sources, and applies the kernel density estimation to analyze dynamic evolutionary characteristics. …”

    Oxidative Nickel-Catalyzed <i>ortho</i>-C–H Amination of (Iso)quinolines with Alicyclic Amines Directed by a Sacrificial <i>N</i>‑Oxide Group by Weiqi Zhu (17845973)

    Published 2024
    “…Transition metal (TM)-catalyzed direct amination of C–H bonds on free or fused pyridine (Py) rings with free amines still remains scarce because amines and the Py ring tend to adopt a nonproductive N-bound coordination with many TMs, leading to a significant decrease of catalytic reactivity. …”

    Table_1_Thinning can increase shrub diversity and decrease herb diversity by regulating light and soil environments.docx by Jiatong Yu (13202610)

    Published 2022
    “…The responses of species diversity to changes in understory vegetation were conducted by a structural equation model (SEM). The results showed that compared with CK, thinning significantly increased the photosynthetically active radiation (PAR) and the light quality (R/FR) (p < 0.05), while decreased the contents of soil total nitrogen (TN), total phosphorous (TP), organic matter (OM), nitrate nitrogen (NN), ammonia nitrogen (AN) and pH. …”
