The Impact of E-commerce on the Upgrading of County-level Industrial Structure—From the Perspective of Export and Enterprise Expansion

This paper takes the "Comprehensive Demonstration Counties for E-commerce in Rural Areas" project as a quasi-natural experiment and empirically analyzes the impact and action mechanism of e-commerce on the transformation and upgrading of the county-level industrial structure through a multi-period DID model. The results show that during the pilot period of the project, e-commerce has significantly promoted the upgrading of the county-level industrial structure. This effect is more pronounced in county-level regions in the western part of China and is influenced by local network resources and agricultural development. Further mechanism analysis shows that e-commerce mainly affects the transformation and upgrading of industrial structure through channels such as expanding product exports and stimulating entrepreneurial vitality

Research on Color Matching Model for Color QR Code

Objective To provide a faster and more effective way for consumers to obtain the additional information of product, the color quick response (QR) code is printed on product packaging. To improve decoding accuracy of color QR codes. This paper constructs a color matching model with good performance, which restrains aliasing between two color encoding modules of color QR code. Methods By comparing and analyzing the character of several typical color spaces, the HSV color space was chosen for its favorable attributes. Based on the enlarging capacity principle of color QR code and the maximum rule of relative Euclidean distance, 2n-1 base-color points are set in the HSV space, and 2n-1 pair-color points are calculated by using color distance equation, resulting in a formula capable of encoding 2n colors. Results Results show that the color gamut of QR code pictures generated using our proposed model is wider than that generated using another color matching model. Color aliasing between two encoding modules was greatly restrained. Conclusion The proposed color matching model offers good performance, based upon wider color gamut and reduced aliasing, for generating color QR codes in the HSV color space. Consumers can scan the printed color QR code on product packaging with their electronic devices to obtain more exhaustive information of product effectively

Bibliometric analysis of research trends on the combination of radiotherapy and PARP inhibitors in solid tumors

IntroductionRadiotherapy has served as a cornerstone in cancer treatment for over a century. However, the efficacy of radiotherapy is often compromised by the intrinsic and acquired radioresistance of tumors, which can lead to treatment failure and disease recurrence. Recent advancements in preclinical and clinical research have highlighted the potential synergistic efficacy of combining radiotherapy with poly-ADP-ribose polymerase inhibitors (PARPi), offering promising therapeutic avenues for solid tumors. This study employs bibliometric analysis to systematically evaluate the evolution, trends, and intellectual landscape of research on the combination of radiotherapy and PARPi in solid tumors.MethodsPublications addressing the combination of radiotherapy and PARPi for solid tumors between 2005 and 2024 were retrieved from the Web of Science Core Collection (WOSCC) database. Bibliometric assessments were conducted using VOSviewer and CiteSpace to analyze publication trends, collaborative networks, and research foci.ResultsA total of 901 articles were included. The United States dominated research output, with the University of Texas MD Anderson Cancer Center identified as the most productive institution. Hannah Farmer emerged as the most frequently cited author. Keywords co-occurrence analysis revealed a thematic shift from foundational studies on molecular mechanisms, such as DNA damage response and mechanism of action of PARPi, toward clinical investigations evaluating combination therapy efficacy and safety in trials.ConclusionThis bibliometric analysis underscores the rapid growth of research on radiotherapy and PARPi combination therapy, with the United States maintaining a leading role due to its extensive scientific infrastructure and collaborative networks. The field has transitioned from mechanistic explorations to translational and clinical applications, reflecting progress toward therapeutic optimization. These findings provide a comprehensive overview of the knowledge structure within this domain and serve as a strategic reference for guiding future research priorities and clinical implementations

Prompting Whole Slide Image Based Genetic Biomarker Prediction

Prediction of genetic biomarkers, e.g., microsatellite instability and BRAF in colorectal cancer is crucial for clinical decision making. In this paper, we propose a whole slide image (WSI) based genetic biomarker prediction method via prompting techniques. Our work aims at addressing the following challenges: (1) extracting foreground instances related to genetic biomarkers from gigapixel WSIs, and (2) the interaction among the fine-grained pathological components in WSIs.Specifically, we leverage large language models to generate medical prompts that serve as prior knowledge in extracting instances associated with genetic biomarkers. We adopt a coarse-to-fine approach to mine biomarker information within the tumor microenvironment. This involves extracting instances related to genetic biomarkers using coarse medical prior knowledge, grouping pathology instances into fine-grained pathological components and mining their interactions. Experimental results on two colorectal cancer datasets show the superiority of our method, achieving 91.49% in AUC for MSI classification. The analysis further shows the clinical interpretability of our method. Code is publicly available at https://github.com/DeepMed-Lab-ECNU/PromptBio.Comment: 11 pages, 3 figures, MICCAI202

Improving yield and water use efficiency of apple trees through intercrop-mulch of crown vetch (Coronilla varia L.) combined with different fertilizer treatments in the Loess Plateau

Improving water use efficiency (WUE) and soil fertility is relevant for apple production in drylands. The effects of intercrop-mulch (IM) of crown vetch (Coronilla varia L.) combined with different fertilizer treatments on WUE of apple trees and soil fertility of apple orchards were assessed over three years (2011, 2013 and 2014). A split-plot design was adopted, in which the main treatments were IM and no intercrop-mulch (NIM). Five sub-treatments were established: no fertilization (CK); nitrogen and phosphorus fertilizer (NP); manure (M); N, P and potassium fertilizer (NPK); and NPK fertilizer combined with manure (NPKM). Due to mowing and mulching each month during July–September, the evapotranspiration for IM was 17.3% lower than that of NIM in the dry year of 2013. Additionally, the soil water storage of NPKM treatment was higher than that of CK during the experimental period. Thus, single fruit weight and fruit number per tree increased with IM and NPKM application. Moreover, applying NPKM with IM resulted in the highest yield (on average of three years), which was 73.25% and 130.51% greater than that of CK in IM and NIM, respectively. The WUE of NPKM combined with IM was also the highest in 2013 and 2014 (47.69 and 56.95% greater than applying IM alone). In addition, due to application of IM combined with NPKM, soil organic matter was increased by 25.8% compared with that of CK (in NIM). Additionally, application of IM combined with NPKM obtained more economic net return, compared to other combinations. Therefore, applying NPKM with IM is recommended for improving apple production in this rain-fed agricultural area

Research progress of coal seam gas content determination technology and equipment

Gas content is an important parameter for the prediction of coal and gas outburst risk, the estimation of coal seam gas resource, and the design of mine gas control engineering. Focusing on how to accurately and quickly determine the gas content of coal seams in large area, and relying on the National Science and Technology Major Project, the National Natural Science Foundation of China, the Joint Fund of Coal Enterprises and other projects to develop scientific and technological research, some progress had been made in sampling and testing, and the main manifestations were as follows. ① The development of sampling for gas content determination in coal seam has gone through four stages, namely, orifice sampling, core tube spot sampling, pressure injection spot sampling, and sealed sampling. The pressure holding capacity of the sealed sampling equipment reached 11.5 MPa, and the diameter of coal core reached 38 mm. ② According to different geological conditions of coal seams, three types of sampling techniques had been developed, including directional long borehole sealed sampling along coal seam, floor cross-layer borehole sealed sampling, and comb-shaped directional long borehole sealed sampling in roof or floor. ③ In the hard coal seams of Jiaozuo mining area in Henan Province and Jincheng mining area in Shanxi Province, the sampling depth of the directional long borehole along the seam reached 516 m, and the gas content of the coal seam measured by the sealed sampling method was increased by an average of 0.44 and 1.04 times compared with the conventional sampling method, respectively. In the broken soft coal seam of the Huainan mining area in Anhui Province, the sealed sampling depth of the cross-layer borehole reached 209 m, and the measured gas content of the coal seam was increased by 0.26 times on average compared with the conventional sampling method. In the broken soft coal seam of the Huaibei mining area in Anhui Province, the comb drilling sealed sampling depth reached 484 m in roof or floor, and the measured coal seam gas content was 0.19 times higher than that of the conventional sampling method. The sealed sampling method was superior than the conventional sampling method in terms of determination accuracy and detection range of coal seam gas content. ④ In terms of gas content testing, in addition to the traditional natural desorption test, a series of coal mine gas content rapid test equipment had been developed, which can measure the gas content of coal seam within 30 min at the earliest, and was generally used for gas content testing in 100-meter hole. It is proposed that the sealed sampling equipment for coal seam gas content determination needs to be developed in the direction of miniaturization and lightweight, and it can realize sealed sampling with the drilling. In the test, a reasonable desorption termination limit should be determined according to the actual situation, and the testing equipment and sealed sampling equipment should be further combined to achieve the rapid and accurate determination of gas content in deep hole. Sealed sampling technology has become the main means of accurate exploration and prediction of coal seam gas content in large areas, and it is an important technical guarantee for the safe and efficient coal mining
