Abstract	This study considers the implementation of the "Broadband China" strategy as an exogenous policy shock and examines the impact of network infrastructure construction (NIC) on the low-carbon innovation (LCI) of enterprises and its underlying mechanisms by using a progressive difference-in-difference model based on the data of Chinese listed enterprises from 2009 to 2020. This study finds that NIC can improve the LCI of enterprises. After the elimination of the sample selection bias and selection of the urban slope as the exogenous instrumental variable, the conclusions remained robust. The results of the mechanism test show that upgrading the human capital level, reducing transaction costs, and alleviating financing constraints are the three important paths through which NIC can help enterprises improve their LCI level. The heterogeneity analysis determines that NIC has considerable comparative advantages for enterprises with executives who have a financial background and enterprises with high knowledge stock. In addition, LCI improvement can further enhance enterprise value. The research conclusions can broaden the microscopic research perspective of enterprise transformation and upgrading theory and provide reliable empirical evidence for China's low-carbon economic transformation.

Abstract	The green financial policy is one of the important policy tools for China to achieve the national carbon peak goal and carbon neutrality through financial means. How financial development affects the growth of international trade has been an important research topic. This paper uses the Pilot Zones for Green Finance Reform and Innovations (PZGFRI) implemented in 2017 as a natural experiment drawing on the relevant data of Chinese provinces' panel data from 2010 to 2019. It adopts a difference in difference (DID) model to assess the impact of green finance on export green-sophistication (EGS). The results report that the PZGFRI significantly improves EGS, and the result remains robust after robustness checks such as parallel trend and placebo. The PZGFRI improves EGS by boosting total factor productivity, industrial structure upgrading, and green technology innovation. Moreover, the role of PZGFRI in promoting EGS is significantly reflected in the central and western regions and the regions with low-marketization levels. This study confirms that green finance is an important factor influencing the quality improvement of China's exports, which provides effective evidence from the reality level for China to vigorously promote the construction of a green financial system in recent years.

Abstract	Green credit is a major policy innovation to guide enterprises to participate in environmental governance actively. This study uses the data of Chinese A-share listed companies from 2007 to 2016, takes the green credit guideline (GCG) issued in 2012 as a quasi-natural experiment, and uses a difference in difference (DID) model to test the effect of GCG on the enterprises' export green-sophistication (EGS) and its internal and external mechanisms. The study finds that GCG improves enterprises' EGS and research and development (R&D) investment is the intermediation channel for GCG to affect EGS. Results of heterogeneity analysis show that the role of GCG in promoting EGS is significantly reflected in enterprises that the government does not subsidize, enterprises in areas with a low degree of financial marketization development, state-owned enterprises, and enterprises with a high degree of equity incentive.

Abstract	This work focused on the effects of the hydrothermal environment on the aging of all-steel radial tire (ASRT) composites. Composite specimens were conditioned by immersion in deionized water at 30, 60 and 90 °C. Its water absorption, thermal and mechanical properties (tensile strength, elasticity modulus, elongation at break and interfacial shear strength), morphological structure, as well as molecular cross-linking reaction were investigated before and after aging. Results indicated that there was no dynamic equilibrium of water absorption of ASRT composites after deviating from the Fickian model. The molecular cross-linking density of the rubber matrix showed an increase in the early stage of aging. Then, the mechanical properties suffered of a drop due to the degradation of the rubber matrix and the poor interface between the steel fiber and rubber matrix. Additionally, a systematic hygrothermal aging mechanism was proposed.

Abstract	Purpose: cervical cancer is the leading cause of cancer deaths in women in the developing world, with high-risk HPV16 and HPV18 accounting for approximately 70% of all cervical cancers. Early detection of HPV, especially high-risk HPV types, is essential to prevent disease progression. Methods: in this study, we established a highly sensitive and specific nucleic acid assay based on a CRISPR-Cas13a/Cas12a dual-channel system combined with multiplex RAA for rapid detection and typing of HPV16/18, which provides a new idea for cervical cancer screening. To meet the application of field testing, we designed a portable fluorescence imaging assay that can judge the test results directly with the naked eye or through cell phone imaging. Results: the lower limit of detection for both HPV16 and HPV18 based on the CRISPR-Cas12a/Cas13a dual-channel assay was 10 Conclusions: this developed portable dual gene assay platform may provide new technical support for cervical cancer screening in resource-limited settings.

Abstract	Background: The morphological structure phenotype of maize tassel plays an important role in plant growth, reproduction, and yield formation. It is an important step in the distinctness, uniformity, and stability (DUS) testing to obtain maize tassel phenotype traits. Plant organ segmentation can be achieved with high-precision and automated acquisition of maize tassel phenotype traits because of the advances in the point cloud deep learning method. However, this method requires a large number of data sets and is not robust to automatic segmentation of highly adherent organ components; thus, it should be combined with point cloud processing technology. Results: An innovative method of incomplete annotation of point cloud data was proposed for easy development of the dataset of maize tassels,and an automatic maize tassel phenotype analysis system: MaizeTasselSeg was developed. The tip feature of point cloud is trained and learned based on PointNet + + network, and the tip point cloud of tassel branch was automatically segmented. Complete branch segmentation was realized based on the shortest path algorithm. The Intersection over Union (IoU), precision, and recall of the segmentation results were 96.29, 96.36, and 93.01, respectively. Six phenotypic traits related to morphological structure (branch count, branch length, branch angle, branch curvature, tassel volume, and dispersion) were automatically extracted from the segmentation point cloud. The squared correlation coefficients (R Conclusion: The proposed method provides an efficient scheme for high-throughput organ segmentation of maize tassels and can be used for the automatic extraction of phenotypic traits of maize tassel. In addition, the incomplete annotation approach provides a new idea for morphology-based plant segmentation.

Abstract	Objective: This study aims to discuss the differential diagnosis value of endometrial volume and flow parameters in combination with serum carbohydrate antigen 125 (CA125) in endometrial benign and malignant lesions. Materials and methods: The data of 250 patients with endometrial lesions were retrospectively analyzed. Carbohydrate antigen 125 (CA125) was determined before the operation. The morphology, hemodynamics, volume and flow parameters of the endometrium were measured by transvaginal three-dimensional-power Doppler angiography (3D-PDA). The endometrial volume (EV), 3D-PDA vascular index (VI), flow index (FI) and vascularization flow index (VFI) were calculated using the virtual organ computer-aided analysis software (VOCAL). Results: According to the pathological results, 202 patients (80.8%) had benign endometrial lesions and 48 patients (19.2%) had endometrial cancer (EC). The endometrium of EC patients was thicker (15.64 ± 7.26 mm vs. 9.24 ± 5.06 mm, P < 0.001), the endometrial volume was larger (9.23 ± 4.08 ml vs. 2.26 ± 3.42 ml, P < 0.001), and the flow parameters VI, FI and VFI were higher, when compared to those of benign lesions (P < 0.001). The area under the receiver operating characteristic curve (AUROCC) of VI receptors was 0.86, while the AUC of endometrial thickness (ET) was only 0.66. Therefore, the best variable for distinguishing benign and malignant endometrial lesions was VI. The level of CA125 in the EC group significantly increased (40.57 ± 17.45 vs. 17.87 ± 7.64, P < 0.001), and the level of CA125 increased (P < 0.05) with the increase in clinical grade, degree of tumor differentiation, and pelvic lymph node metastasis (P < 0.05). However, the difference in myometrial invasion was not statistically significant (P > 0.05). Conclusion: Transvaginal 3D-PDA can clearly show the morphological and hemodynamic characteristics of endometrial lesions, and assist in the detection of EC in combination with serum CA125. This may have important clinical application value.
