    Abstract Lexical features are influenced by different languages and genres. The study of lexical features in different genres of texts on the same topic is helpful to understand the universalities and peculiarities of languages. This study constructs a research on the lexical feature and word collocations of two self-build corpora (China's economic Legal Policy Corpus and English News Corpus during the COVID-19 pandemic), the methods of Quantitative Linguistics and context interpretation are adopted. It was found that: (1) the word length, word frequency, word cluster and high frequency word distribution in English economic news and Chinese economic legal policies are influenced by language and genre to some extent, and they conform to different functional image distribution; (2) during the COVID-19 pandemic, “development” has been the focus of China's economic legal policies and English news, the two have attached importance to economic recovery and taken a positive attitude toward it in different ways. These findings suggest that: (1) There are some universalities and peculiarities between English economic news and Chinese economic legal policies in the distribution of lexical feature; (2) there is a certain synchronization between laws and news, and both of them maintain a positive and objective attitude toward the economic development during the pandemic. This study carries out a macroscopic investigation on internal structure and external interpretation, which enriches the study on lexical features and cultural features of language and provides some references for relevant studies.

    Abstract Online reviews contain comparative opinions that reveal the competitive relationships of related products, help identify the competitiveness of products in the marketplace, and influence consumers’ purchasing choices. The Class Sequence Rule (CSR) method, which is previously commonly used to identify the comparative relations of reviews, suffers from low recognition efficiency and inaccurate generation of rules. In this paper, we improve on the CSR method by proposing a hybrid CSR method, which utilises dependency relations and the part-of-speech to identify frequent sequence patterns in customer reviews, which can reduce manual intervention and reinforce sequence rules in the relation mining process. Such a method outperforms CSR and other CSR-based models with an F-value of 84.67%. In different experiments, we find that the method is characterised by less time-consuming and efficient in generating sequence patterns, as the dependency direction helps to reduce the sequence length. In addition, this method also performs well in implicit relation mining for extracting comparative information that lacks obvious rules. In this study, the optimal CSR method is applied to automatically capture the deeper features of comparative relations, thus improving the process of recognising explicit and implicit comparative relations.

    Abstract ABSTRACT: Rural areas are multifunctional and often have production, living, and ecological functions. The high-quality and balanced development of these three functions is key to sustainable rural development (SRD). Thus, the evaluation of SRD based on rural multifunctionality is of immense significance. This study clarifies the relationship between multifunctionality and sustainable rural development. An evaluation index system with six sub-components was established for calculating the SRD. In addition, we included 129 counties from the Sichuan Province in our case study, and used this index system to analyze the characteristics of rural multifunctionality for evaluating the SRD. The results showed indisputable evidence of multifunctional development. At the county level, rural multifunctionality faces the challenge of insufficient and uneven development, particularly in production functions. Significant spatial differences existed in rural multifunctional development, and the suburban counties generally performed better. Moreover, a mutually reinforcing relationship between production, living, and ecological functions was established; however, there was still a significant gap in realizing SRD. Our results emphasize the necessity of a differentiated SRD strategy that should be formulated and implemented based on rural multifunctionality differentiation rules. Our study offers useful guidance for realizing rural multifunctional and sustainable development.

    Abstract Water shortage has become a widespread problem worldwide. Preparation of water resource balance sheet forms the basis of regional environmental governance in China and is of great importance for achieving the sustainable development. This study is an attempt of developing a water resource accounting system on an accrual basis by preparing balance sheet and other essential supporting statements for Wuhan within the framework of a parallel reporting system, which is oriented to different objectives. The results show that during 2014–2020 the physical volume of Wuhan’s water resources fluctuated with net precipitation to a large extent. Since 2017, the value of Wuhan’s water has kept increasing even though the water volume of 2017–2019 still declined due to the earlier drought. This demonstrates a relatively better water management performance during the current terms of office, which indicates a positive role of the leadership accountability system based on natural resource balance sheeting that is being implemented in China. This study contributes to the literature on regional water resources accounting and environmental management. The water resource statements prepared for Wuhan, Hubei, China have a good level of generality. They provide a reliable basis for the local government’s performance assessment of water resources management and facilitate the implementation of water resource related policies.

    Abstract Entropy is an important indicator to measure network heterogeneity. We propose a new network structure entropy, SP (series-parallel) structure entropy, based on the global network topology while adding a medial measure that considers the series-parallel structure. First, the results of special networks show that SP structure entropy can overcome other structure’s entropy deficiencies to some extent. Then, through simulation analysis of typical networks, the validity and applicability of SP structure entropy in describing general networks are verified. Finally, we analyze an enterprise consulting network to demonstrate the superiority of the SP structure entropy for real network analysis.

    Abstract Type 2 immunity in the lung protects against pathogenic infection and facilitates tissue repair, but its dysregulation may lead to severe human diseases. Notably, cannabis usage for medical or recreational purposes has increased globally. However, the potential impact of the cannabinoid signal on lung immunity is incompletely understood. Here, we report that cannabinoid receptor 2 (CB2) is highly expressed in group 2 innate lymphoid cells (ILC2s) of mouse and human lung tissues. Of importance, the CB2 signal enhances the IL-33-elicited immune response of ILC2s. In addition, the chemogenetic manipulation of inhibitory G proteins (Gi) downstream of CB2 produces a similarly promotive effect. Conversely, the genetic deletion of CB2 mitigates the IL-33-elicited type 2 immunity in the lung. Also, such ablation of the CB2 signal ameliorates papain-induced tissue inflammation. Together, these results have elucidated a critical aspect of the CB2 signal in lung immunity, implicating its potential involvement in pulmonary diseases.

    Abstract Objective. To investigate the clinical application of the three-dimensional (3D) radiomics model of the CT image in the diagnosis and identification of ureteral calculus and phlebolith. Method. Sixty-one cases of ureteral calculus and 61 cases of phlebolith were retrospectively investigated. The enrolled patients were randomly categorized into the training set (n = 86) and the testing set (n = 36) with a ratio of 7 : 3. The plain CT scan images of all samples were manually segmented by the ITK-SNAP software, followed by radiomics analysis through the Analysis Kit software. A total of 1316 texture features were extracted. Then, the maximum correlation minimum redundancy criterion and the least absolute shrinkage and selection operator algorithm were used for texture feature selection. The feature subset with the most predictability was selected to establish the 3D radiomics model. The performance of the model was evaluated by the receiver operating characteristic (ROC) curve, and the area under the ROC curve (AUC) was also calculated. Additionally, the decision curve was used to evaluate the clinical application of the model. Results. The 10 selected radiomics features were significantly related to the identification and diagnosis of ureteral calculus and phlebolith. The radiomics model showed good identification efficiency for ureteral calculus and phlebolith in the training set (AUC = 0.98; 95%CI: 0.96–1.00) and testing set (AUC = 0.98; 95%CI: 0.95–1.00). The decision curve thus demonstrated the clinical application of the radiomics model. Conclusions. The 3D radiomics model based on plain CT scan images indicated good performance in the identification and prediction of ureteral calculus and phlebolith and was expected to provide an effective detection method for clinical diagnosis.

    Abstract Gravels can protect soil from wind erosion, however, there is little known about the effects of fine-grained gravel on aerodynamic characteristics of the near-surface airflow. Drag coefficient, wind-speed gradient, and turbulent transfer coefficient over different coverages of gravel surfaces were investigated in a compact boundary-layer wind tunnel. The drag coefficient of the fine-grained gravel surface reached the maximum value at 15% coverage and then tended to stabilize at gravel coverage 20% and greater. At a height of 4 cm, near-surface airflow on gravel surfaces can be divided clearly into upper and lower sublayers, defined as the inertial and roughness sublayers, respectively. The coefficient of variation of wind speed over gravel surfaces in the roughness sublayer was 8.6 times that in the inertial sublayer, indicating a greater effect of gravel coverage on wind-speed fluctuations in the lower layer. At a height of 4 cm, wind-speed fluctuations under the observed wind speeds were independent of changes in gravel coverage. In addition, an energy-exchange region, where sand particles can absorb more energy from the surrounding airflow, was found between the roughness and inertial sublayers, enhancing the erosional state of wind-blown sand. This finding can be applied to evaluate the aerodynamic stability of the gravel surface in the Gobi Desert and provide a theoretical basis for elucidation of the vertical distributions of wind-blown sand flux.

    Abstract Understanding the distribution patterns and underlying maintenance mechanisms of insect species is a core issue in the field of insect ecology. However, research gaps remain regarding the environmental factors that determine the distribution of insect species along altitudinal gradients in Guandi Mountain, China. Here, we explored these determinants based on the distribution pattern and diversity of insect species from 1600 m to 2800 m in the Guandi Mountain, which covers all typical vegetation ecosystems in this area. Our results showed that the insect community showed certain differentiation characteristics with the altitude gradient. The results of RDA and correlation analysis also support the above speculation and indicate that soil physicochemical properties are closely related to the distribution and diversity of insect taxa orders along the altitude gradient. In addition, the soil temperature showed an obvious decreasing trend with increasing altitude, and temperature was also the most significant environmental factor affecting the insect community structure and diversity on the altitude gradient. These findings provide a reference for exploring the maintenance mechanisms affecting the structure, distribution pattern, and diversity of insect communities in mountain ecosystems, and the effects of global warming on insect communities.
