    The influence of digital village construction on agricultural green development-based on the mediate role of industrial structure upgrading by Zhaoguang Li, Kai Hu, Qinying Shi

    Published 2025-01-01
    “…The role and mechanism of China's digital rural construction in promoting the green development of the whole process of agricultural production needs further analysis.MethodsBased on the panel data of prefecture-level cities in Henan Province from 2013 to 2022, we used the entropy topsis model, the fixed effect model, the Tobit regression model, the intermediate effect model, and the threshold effect model, aiming to explore the effects of digital village construction on agricultural green development and their regional differences, impacts paths and non-linear effects.ResultsThe study found the following: (1) The level of agricultural green development and the digital village construction have increased in Henan province, with the latter exhibiting a spatial clustering phenomena. (2) Digital village construction has a significant positive effect on green agricultural development, but this effect does not exist in mountainous areas. (3) The digital village construction can impact green agricultural development through the updating of agricultural structures. (4) The positive influence of digital village construction on green agricultural development is non-linear, with a single-threshold and increasing marginal effects.DiscussionThese findings provide references for other countries to use digital elements to promote green and sustainable development of agriculture. …”

    Road to green urbanization: how does urbanization process affect the green land use efficiency by Ruoxi Yang, Jiayao Wang, Minghao Xu, Ke Xu

    Published 2025-04-01
    “…This conclusion remains valid after conducting endogeneity and robustness tests. (2) The mediating effect test shows that the urbanization process can increase synergistic industrial agglomeration and promote the optimization of the industrial structure, thus indirectly promoting the improvement of green land use efficiency. (3) The threshold effect test shows that a threshold effect exists in the relationship between the level of economic development and green land use efficiency, based on the urbanization process. …”

    High-Precision Chip Detection Using YOLO-Based Methods by Ruofei Liu, Junjiang Zhu

    Published 2025-07-01
    “…GM-YOLOv11-DNMS has two main improvements: (1) it replaces the CNN layers with a ghost module in YOLOv11n, significantly reducing the computational cost while maintaining the detection performance, and (2) it uses a new dynamic non-maximum suppression (DNMS) method, which dynamically adjusts the thresholds to improve the detection accuracy. …”

    Fast detection method for radionuclides based on Sequential Bayesian approach by WAN Linjian, ZHANG Xuan, ZHANG Chunlei, HUANG Jianwei, LIU Jiacheng, ZHANG Xiaole, LI Dehong, YANG Zhijun

    Published 2025-01-01
    “…Based on the principle that the time interval between adjacent two rays was exponential distributed, the decision was caculated by collecting a series of ray time samples in chronological sequence, and decisions were made by comparing the decision function with the preset upper and lower thresholds. Finally, experimental verifications were conducted on the feasibility, detection performance, and universality of the method by placing a set of standard point sources at different distances from the front of a LaBr3(Ce) detection system in both low and natural radiation background environments. …”
