Objectives: It is difficult for the traditional traffic information acquisition method to obtain the real-time dynamic traffic flow information of large scope and full coverage. With urbanization, the increasing number of supertall buildings makes the city skyline a favorable platform for earth observation. This paper studies the urban remote sensing video production and traffic information extraction method using the urban skyline as the observation platform. Methods: First, the earth observation data shooting is carried out in the super-tall buildings. Then, the original oblique observation data is corrected by orthography, which is further fused with the satellite image to generate a large range of remote sensing video data of the city. Finally, we train a deep learning model and use it for vehicle classification and identification. The number and density of vehicles in the area are calculated based on the identification results. Results: This paper carries out data collection and processing analysis on the sightseeing floor of Ping, an Building in Shenzhen. Results show that the proposed method can produce low-cost, long-time, large-scale and high-quality urban remote sensing video. The vehicle detection based on the remote sensing video have high accuracy. Conclusions: The proposed framework can be used to effectively monitor the regional traffic flow and sever for the smart city management. Furthermore, based on its capability of long-time, high-resolution, full-coverage and real-time remote sensing, this method can also be applied to many other urban management fields, such as urban disaster emergency response, crowd monitoring, and construction site monitoring.

Under the strategic background of implementing the new development concept, there is an important question to be answered about whether the' responsibility to people' water pollution control policy can promote corporate green innovation while improving the environment. Based on the panel data of Shanghai and Shenzhen A-share listed companies from 2009 to 2019, this paper empirically tested the impact of the implementation of the river chief system on corporate green innovation using the multi-period DID method. This research concluded that the river chief system could significantly improve corporate green innovation. After a series of necessary tests, such as the parallel trend test and placebo test, the conclusion remained robust. The mechanism analysis showed that the policy effect of the river chief system was mainly realized through two channels, namely, internal incentive and external pressure, and that the effect of external pressure was stronger than that of internal incentive. Further research showed that the governance power of local river chiefs had a lax effect at the boundaries of prefecture-level cities, and the promotion incentives of officials also affected the policy effect to a certain extent. More importantly, under the policy background of the river chief system, local officials were more active in water pollution control and could also monitor enterprises far away from the rivers. In addition, the results of the heterogeneity analysis showed that: ① Compared with small enterprises, large enterprises received more attention from policymakers, and the river chief system had a stronger regulatory impact on large enterprises, whose green innovation level had a more significant improvement. ② Compared with private enterprises, state-owned enterprises responded more positively to the river chief system policy, and the green innovation output stimulated by the policy was higher. ③ Compared with other industries, enterprises in the water pollution industry were less affected by the river chief system policy. This paper found that these enterprises mainly dealt with environmental governance pressure by reducing production rather than focusing on green innovation. This study provides a policy basis for implementing the environmental regulation policy of' responsibility to people' and for realizing the dual goals of environmental protection and economic development. It also provides theoretical support and practical inspiration for the refined implementation of environmental regulation policies from multiple perspectives, such as internal incentives, external media supervision, and enterprise heterogeneity.

The digital twin city seeks to restore virtually the geographic scene that is close to reality and provide the audience an immersive experience. Three dimensional (3D) real urban scene is one of the key technologies to achieve the goal. Nowadays, the combination of geographic information system and game engine becomes an industrial trend and provides new opportunities for 3D real urban scene. Oblique photogrammetric data, as being a fundamental data source for 3D urban modeling, is able to represent large-scale and high-precision scene. The game engine plays an excellent role in offering realistic effects and post-production systems that are greatly useful for geospatial data visualization. However, the diversity of specifications and formats of oblique photogrammetric data has caused many different data loading and transformation methods, resulting in a problem to be solved in 3D real urban scene. Methods: This paper aims to propose a data transformation approach from oblique photogrammetric data to rendering resources in game engine. To stress, the proposed approach can allow us to load instantly massive amount of oblique photogrammetric data in Unreal Engine, which is one of the most popular game engines. We further compared oblique photogrammetric data with rendering resources in game engine and discussed the significance of such a data transformation. The approach reorganizes the original structure of the data by parsing data into a tree structure that better suits transformation purposes. Also, the proposed approach transforms respectively the geometry and texture data when iterating tree nodes, as well as considers the essential physical properties of rendering assets. All these features are combined into a package data format. Results: In the case study of Futian district, Shenzhen, the results show that the proposed approach successfully converts oblique photogrammetric data to rendering resources in Unreal Engine 4. In the transformation process, the geometrical structure and collision properties of triangular mesh are guaranteed, and color, bump and other visual elements of original data are kept in materials. The rendering resources are loaded to simulate the real urban scenarios at different time periods of a day in Unreal Engine 4. Conclusions: This paper devises a novel approach which can convert the oblique photogrammetric data into rendering resource for a game engine to load and render, and meantime maintain the consistency of data's geometry and texture. For its scalability, it also supports parallel processing of large-scale data transformation when data is organized in the same directory. The proposed approach may be of great theoretical and practical value for other related 3D model data transformation problems. [ABSTRACT FROM AUTHOR]

Current research predominantly relies on single travel data sources to simulate single-modal transportation networks, making it challenging to objectively and comprehensively reflect the real travel characteristics of residents. This paper presents a modeling method of multi-modal transportation network and a multifeature fusion algorithm for analyzing resident travel characteristics, taking Shenzhen as a case study. Firstly, taking into consideration the spatio temporal variations in transportation networks, a partitioning algorithm of multiscale transportation zones is designed to simplify the complex network. Next, a multi-model transportation network is constructed by connecting station path attributes with transportation zones. Finally, mobile trajectory mining and feature fusion techniques are adopted to design a fusion algorithm of multi-modal travel features, systematically depicting resident travel characteristics in a multi-model context. Experimental results demonstrate what compared to using a single data source alone, the proposed method effectively mitigates data bases, provides a more accurate representation of traffic density among different transportation regions, and offers a more comprehensive insight into residents' travel behaviors and preferences, and can better provide scientific decision-making for urban planning and transportation management.

In this study, the fatty acid composition and content in human milk of different cities and lactational periods were analyzed. A total of 204 human milk samples were collected from Baotou (n=41), Beijing (n=40), Jinan (n=20), Kunming (n=33), Shenzhen (n =21) and Xining (n=49), including colostrum (n =28), one month postpartum (n =67), and four month postpartum (n=109). The content of fatty acids in human milk was analyzed by gas chromatography using C11: 0 as the internal standard. This study investigated the effects of lactational period and geographical location on fatty acids content of human milk in China. The results showed that the fat content in mature human milk was significantly higher than that in colostrum (P<0.05), the fat content in Jinan human milk was the highest (5 g/100 mL), and the lowest were Kunming and Shenzhen (<3.0 g/100 mL). The content of C16) 0 during lactation was relatively stable at around 192 mg/g fat. The colostrum was rich in long-chain unsaturated fatty acids, and the content of C18)2 n-6c and C18)3 n-3 in colostrum was significantly lower than that in mature human milk (P<0.05). There were certain differences in the fatty acid content of human milk in different regions, and the ratio of linoleic acid/linolenic acid varies greatly. Further comparisons were made between the data in this paper and the fatty acid content of human milk in other countries. This study provided theoretical support for the quantitative analysis of human milk fatty acids as well as the influencing factors of human milk fatty acids concentration. [ABSTRACT FROM AUTHOR]

[Objective] The present paper aimed to reveal the mechanism of action of soil bacterial community environment in woodland under different restoration patterns. [Method] Using high-throughput sequencing technology, we analyzed the relationship between soil physicochemical properties and dominant bacterial communities through the composition and diversity of soil bacterial communities in southern Aquilaria sinensis, Acacia mangium forests and natural secondary woodlands. [Result] (i) In the taxonomic study of soil bacteria in different forest stands, there were 44, 32 and 35 phyla of soil bacteria in the Aquilaria sinensis, Acacia mangium and secondary forest, respectively.The composition of soil bacteria in the three forest stands was relatively similar, and the dominant bacterial groups were Proteobacteria and Acidobacteria, and the communities with relative abundance ＞1% were all Actinobacteria, Verrucomicrobia and Planctomycetes. (ii) In the α-diversity analysis of soil bacteria in different forest stands, the highest Chao1 index of secondary forest soil indicated the highest bacterial community in this soil, and the highest Shannon index of soil sedum forest soil indicated high bacterial diversity in this soil. (iii) In the β-diversity analysis of soil bacteria in different forest stands, the soil bacterial community structure of soil sedum forest and Acacia mazanensis forest was differential, while the secondary forest had similar soil bacterial structure to the former two. (iv) In the RDA redundancy analysis of soils in different stands, Phytophthora variegata and Phytophthora floxa were significantly and positively correlated with fast-acting potassium, effective phosphorus and total phosphorus. Acidobacteria were negatively and significantly correlated with soil pH, effective phosphorus and fast-acting potassium. [Conclusion] The results reveal the structural variability and diversity of soil bacterial community composition in three different forest stands in Shenzhen, and provide a theoretical basis for further exploring whether the artificial restoration model is superior to natural forests.

Big data, a vital driving force of high-quality economic development in China, improves both the speed and efficiency of information exchange and knowledge dissemination. Existing studies have conducted a series of discussions on the dividend effect of big data development, but few have analyzed it from the perspective of corporate green development. Based on the theoretical analysis of the impact of big data development on the internal mechanisms of corporate green technology innovation and on the regulatory role of intellectual property protection, in light of the exogenous policy shock from the ‘National Big Data Comprehensive Pilot Zones,’ this paper studied the A-share listed companies in Shanghai and Shenzhen by adopting the difference-in-differences model (DID) to evaluate the impact of big data development on corporate green technology innovation and the moderating effect of intellectual property protection between them. The research results showed that the development of big data significantly promoted corporate green technology innovation, and that the conclusion still held after a series of robustness tests. Heterogeneity tests showed that the promoting effect of big data development on corporate green technology innovation was more observable in large-scale enterprises, state-owned businesses, and companies with high-level access to data from local governments. The mechanism test indicated that the development of big data could promote corporate green technology innovation by improving the intensity of regional environmental regulation, easing the financing constraints of enterprises, and improving their human capital level. The moderating effect test showed that intellectual property protection played a significant positive moderating role between big data development and corporate green technology innovation. Accordingly, the government should improve the big data development policies to promote deep integration of big data and the real economy in a consistent manner, reinforce the system design concerning corporate green technology innovation guided by policies of big data development, and combine big data development with green development goals such as achieving peak carbon emissions and carbon neutrality. Meanwhile, policies should be refined based on different types of enterprises in different regions so that a long-term mechanism can be established to support corporate green innovation development. It is also necessary to strengthen the construction of an intellectual property protection system so as to accelerate corporate green technology innovation and green development more effectively.

A large-section rectangular pipe-jacking tunnel in Shenzhen passed through the bridge pile foundation of an interchange ramp with only a distance of 0.8 m, and down-traversed multi-purpose networks for underground pipelines with only a distance of 3 m. Relying on the tunnel project, the design of the segment of the rectangular pipe-jacking tunnels with large sections and the complex condition was studied in detail. A design flow of the design of the segment of the rectangular pipe-jacking tunnels with large sections and a complex condition was proposed. The design elements of the segment configuration of the rectangular pipe-jacking tunnels with large sections were analyzed. The configuration of the segment was designed. Then three working conditions, including the lifting of the segments, the construction pushing condition, and normal service conditions, were assessed using numerical analysis to determine the dimension of the structures. The joints of the segments, longitudinal connections, reserved holes and so on were specially designed considering the properties of the project with large sections, deep-covered soils and high water pressure. Based on the case investigation, contrastive analysis and practical verification, the paper drew the conclusion that the proposed design flow and the design elements were much helpful for the design of the rectangular pipe-jacking tunnels with large sections in complex condition.

In Paul Willis’s “Learning to Labour”, the lads articulate ‘anti-school culture’ as their reaction after penetrating/seeing through the schooling mechanism. This paper will demonstrate some other reactions to seeing through the school system, through the case of migrant workers in Shenzhen China. These reactions are: bypass, repair, and “mobile learning”. By analyzing the learning strategies displayed by a group of young migrant workers in an electronics factory, who left school out of choice but were keen to learn, this paper argues that “mobile learning” allows social actors to imagine and realize new possibilities without challenging the existing structure. Migrant workers use this method to bypass and repair the school system which is falling apart. This paper points out that migrant workers who drop out from school are not “bad students.” This label is not helpful for understanding their situation or for solving their problems. Their problems cannot be solved by exhausting various resources to help them become “good students.” These young migrant workers are not backward, unteachable, unmotivated, or unwilling to learn. Rather, they saw through the middleclass nature of schooling and its urban bias, and realized it cannot possibly help them improve their livelihoods. They become wage labourers in factories in Shenzhen as the result of finding alternatives. Migrant workers who engage in “mobile learning” move to different places and social contexts. On the one hand, through “legitimate peripheral participation,” they gain knowledge and skills in that social context, and they collate and assemble such learning resources for their own use. On the other hand, they mobilize cultural taste, social experiences, and symbols between urban and rural settings, and thus create social, cultural, and symbolic capital which enables them to transform their subjectivities in response to the failure of the schooling system. However, “mobile learning” has its limitations. All the resources, opportunities, and every transition of this learning process is not institutionalized. “Mobile learning” relies largely on waiting, coincidences, the appreciation of supervisors and workers’ own extra labor (such as showing loyalty, hard work, diligence, etc.). In short, the path of migrant workers’ “mobile learning” is thin and easily ruptured. [ABSTRACT FROM AUTHOR]
