Abstract The year of 2020 has been overshadowed by the COVID-19 pandemic. Medical workers throughout China have played critical roles in battling severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) and saving lives. The whole of society has now fully realized the significance of medical workers and many began to think about medical education in China: How can we further improve medical education for the next generation of clinicians, medical scientists, nurses, public-health workers and administrators related to medical care, so that they are well prepared to meet societal needs for medical care in the ever-changing world? In this panel discussion, medical-education experts from several prominent medical schools in China gathered to discuss the reform and future development of China's medical education.

Full textAbstract:
Today, the world is witnessing an enormous new economic wave, which has become an important and growing contributor to economic development. However, few studies compare the overall development of all new economic sectors in different cities or countries. Therefore, the purpose of this study is to contribute to the literature on the 21st century new economy in China, which is viewed as a crucial development direction. Accordingly, the new economic situation in 2018 in 15 major cities of China is evaluated by constructing an index system and adopting some new big-data technologies, whereby a new economy comprehensive index (NECI) for each city is obtained. This study finds that the cities ranked from high to low in the NECI are Beijing, Shanghai, Shenzhen, Guangzhou, Hangzhou, Wuhan, Chengdu, Nanjing, Chongqing, Suzhou, Zhengzhou, Wuxi, Tianjin, Qingdao, and Xi’an. Among them, Beijing, Shanghai, and Shenzhen belong to the first hierarchy. The findings provide a nuanced perspective on the intercity comparison of the new economy, and the index system presented in the study is urgently-needed for policy makers. Finally, based on the case study of Chengdu the study offers rich insights to city administrators in terms of how to promote the new economy.

Full textAbstract:
Abstract Electronic-hailing (e-hailing) has experienced explosive growth in China. The Chinese government’s e-hailing policies illustrate its central–regional policy mix. This study analyzes e-hailing policies in four Chinese cities—Xi’an, Chengdu, Beijing, and Guangzhou—and compares these policies with goals in four policy areas. We show that local Chinese governments’ attitudes toward e-hailing are varied, contradictory, and in some cases even not in accordance with central government policies. Our insights demonstrate the limited generalizability of the policymaking experiments we studied. It would be difficult to infer broad policy implications from the experience any of the four cities has had with e-hailing, because China’s regionally decentralized innovation system and policy experiment process address the unique needs and contexts of regional governments on a case-by-case basis.

China Rail Express (CRE) is the international container train line that runs between China and Europe. Since the implementation of China’s Belt and Road initiative, CRE has developed rapidly. As most CRE trains travel directly from source to destination without load consolidation, CRE faces issues such as an insufficient cargo supply, a low load factor, and a low profit margin. To address these problems, we analyzed the selection of potential consolidation centers and the optimization of consolidation routes to these centers from the perspective of complex network evolution. First, we constructed rules for generation and evolution of the complex network. Next, we generated logistics connection topology networks for CRE from 2013 to 2017 using those rules. We then optimized the consolidation routes based on the network structures formed from those rules. Chongqing, Xi’an, Chengdu, Zhengzhou, Shenyang, Lanzhou, Urumqi, and Tianjin were selected as potential consolidation centers. We conclude with a sensitivity analyses and a discussion of management implications for CRE.

By constructing an evaluation system for the high-quality development of innovation and entrepreneurship, an evaluation index system was established in this study from five aspects: the background, process, input, output, and transformation of innovation and entrepreneurship, and analytic hierarchy process (AHP) and entropy method (EM) were adopted to perform combination weighting. Then, the core of each subsystem and the comprehensive score were calculated based on the TOPSIS method, the high-quality development level of urban innovation and entrepreneurship in 19 vice-ministerial cities like Beijing, Shanghai, Tianjin, Chongqing, Guangzhou, Shenzhen, and Chengdu in China was measured, and the innovation and entrepreneurship development level and structural characteristics were analyzed from five aspects. The results show that Shenzhen, Shanghai, Beijing, Nanjing, and Guangzhou take the lead in the high-quality development of innovation and entrepreneurship, while Xi’an, Chengdu, Hangzhou, Wuhan, Qingdao, Jinan, and Ningbo are in the medium level. Chongqing, Shenyang, Dalian, Harbin, Xiamen, and Changchun perform poorly in the development of innovation and entrepreneurship with problems of interregional large gradient difference in capacity and unbalanced development, which provides an important reference for understanding the current situation, advantages, and disadvantages of innovation and entrepreneurship education development in various economic zones.

Abstract. Particulate matter (PM2.5) concentrations in China have decreased significantly in recent years, but surface ozone (O3) concentrations showed upward trends at more than 71 % of air quality monitoring stations from 2015 to 2021. To reveal the causes of O3 increases, O3 production sensitivity is accurately diagnosed by deriving regional threshold values of the satellite tropospheric formaldehyde-to-NO2 ratio (HCHO/NO2), and O3 responses to precursor changes are evaluated by tracking volatile organic compounds (VOCs) and NOx with satellite HCHO and NO2. Results showed that the HCHO/NO2 ranges of transition from VOC-limited to NOx-limited regimes apparently vary among Chinese regions. VOC-limited regimes are found widely over megacity clusters (North China Plain, Yangtze River Delta and Pearl River Delta) and concentrated in developed cities (such as Chengdu, Chongqing, Xi'an and Wuhan). NOx-limited regimes dominate most of the remaining areas. From 2013 to 2021, satellite NO2 and HCHO columns showed an annual decrease of 3.0 % and 0.3 %, respectively, indicating an effective reduction in NOx emissions but a failure to reduce VOC emissions. This finding further shows that O3 increases in major cities occur because the Clean Air Action Plan only reduces NOx emissions without effective VOC control. Based on the O3–NOx–VOC relationship by satellite NO2 and HCHO in Beijing, Chengdu and Guangzhou, the ozone concentration can be substantially reduced if the reduction ratio of VOCs/NOx is between 2:1 and 4:1.

Wound healing in diabetic patients is a difficult problem to be solved at present. In addition, patients with diabetes have an increased risk of postoperative wound complications. “She-Xiang-Yu-Hong” (SXYH) ointment is a type of traditional Chinese medicine (TCM) compound used to treat wounds. Over the past few years, SXYH has been applied in the Affiliated Hospital of Chengdu University of TCM (Chengdu, China) for the treatment of diabetic foot infections and bedsores, whereas there has been rare research on the effect of SXYH ointment on wound healing. In this study, SXYH ointment was first applied to streptozotocin (STZ)-triggered diabetic ICR mice (4–6 weeks, 20 ± 2 g) to observe the accelerated wound healing and the shortened wound healing period. As indicated by the histology and biochemistry analyses of skin biopsies, the wounds treated using SXYH ointment showed an increase in the granulation tissue. Moreover, SXYH also modulated the inflammation response by regulating affinity proinflammatory cytokines release (e.g., IL-6 and TNF-α). Furthermore, SXYH ointment obviously improved collagen fiber deposition and tissue on the wound surface. On the whole, this study indicated that SXYH ointment could accelerate wound healing, promote blood vessel formation, and suppress inflammations. Thus, the clinical potential of SXYH ointment was demonstrated in the treatment of diabetes and refractory wounds.

Full textAbstract:
As an important part of the national economy, the real estate market is closely related to macro policies, investor confidence, etc., and at the same time shows regional heterogeneity. This study explores the real estate market in four typical cities in China (Beijing, Xi'an, Xiamen, and Chengdu) and analyzes the correlation between real estate prices, sales area, real estate development investment, market investor confidence, and money supply. Through analysis based on the VAR model, it is found that the real estate markets in different cities present their own specific interactive influence patterns. The various factors in Beijing are more closely related and have a continuous impact; other cities have similar characteristics, and the impact of each factor is somewhat different. Therefore, when formulating real estate macro-management policies, it is necessary to consider the market characteristics of different cities and the comprehensive impact of external factors to formulate more targeted strategies and mitigate the potential impact of market fluctuations on the economy.

Drawing from the Uses and Gratifications Theory (UGT), this study explores the influences of the gratifications derived from the use of the WeChat on Chinese consumers’ purchase intention for South Korean brands. A total of 2,276 respondents from ten cities in China—Beijing, Shanghai, Guangzhou, Shenzhen, Ji’nan, Nanjing, Zhengzhou, Wuhan, Chengdu, and Xi’an—were part of this study. Structural equation modeling (SEM) and PROCESS analysis was applied to examine the data. Gratifications that Chinese consumers receive from the WeChat, such as functional information, entertaining information, social interaction, brand interaction, and self-concept, positively influence their brand identity. In addition, the identity of South Korean brands positively correlated with consumer’s purchase intention in China. More importantly, by using a moderated mediation model, this research finds that the relationship between SNS (social networking service) content marketing and purchase intention is influenced by consumers’ regulatory focus and CSR performance of South Korean enterprises for COVID-19 in China. This study’s findings could extend the existing theoretical framework on applying the Uses and Gratifications Theory to social media. In addition, results are in line with those authors who suggest that local social media use may positively affect foreign brand promotion. Theoretical and practical implications are also discussed.

Full textAbstract:
This paper studies the relationships between network capabilities and innovation development in the context of two types of innovation networks: scientific knowledge networks (SKN) and technological knowledge networks (TKN). Focusing on two types of network capabilities, namely acquisition capability and control capability, the paper uses spatial regime models to compare the impacts of multiple factors on different spatial regimes. The main conclusions are the following. First, as regards SKN, the political-administrative hierarchy has shaped the spatial evolution of acquisition capacity, forming a pattern consisting of three dominant cities (Beijing, Shanghai, Nanjing), three subsidiary cities (Guangzhou, Hangzhou, Wuhan), and multiple lesser centers (Tianjin, Chengdu, Xi’an). Moreover, high control capability cities are mainly clustered in the coastal areas, specifically, one monocentric city (Beijing) and two polycentric metropolises (Shanghai, Wuhan). Second, for TKN, cities with high acquisition and control also are mainly found in coastal areas, with Shanghai and Beijing dominating network capabilities. The model’s analysis confirms the positive effect of network capabilities on innovation development, especially in scientific knowledge networks, and the driver for regional innovation development appears to have shifted from global pipeline (globalization) to local buzz (localized talents). This paper concludes with suggestions regarding network capabilities’ potential to reduce regional inequality and achieve sustainable development of regional economies.

Full textAbstract:
Sustainability Label (SL) have emerged as an important product attribute in recent decades, and have evolved into various types as products with social, environmental, and economic benefits have become more prevalent in the marketplace. With the information of SL in products, consumers are encouraged to embrace environmental sustainability principles and to make environmentally sustainable choices and actions. SL helps alignment between consumers and the industry by enhancing consumers’ understanding of company’s act, and serve as an effective marketing message. However, there is limited research on consumer preferences for different types of sustainable labels or benefits. This study addresses this knowledge gap by applying choice experiment method to assess consumers’ choice behavior for products associated with various SL. Choice experiment designs are separately developed for two most relevant sustainable products (i.e. soymilk and EV) in China. A stated preference method (SPM) consumer survey was conducted in 2022 across six major cities in China, namely Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu, and Xi’an, and a total of 840 valid responses were collected for assessing multinomial logit (MNL) model. Findings show that Chinese consumers prefer SL with environmental benefits, foreign COO/Brand in consuming soymilk, and prefer SL with employee friendliness, domestic COO/Brand for Electric Vehicle (EV). These findings provide insights for marketers and researchers Chinese consumers’ preference for specific SL and brand for two selected product categories.

Full textAbstract:
Archaeological museums are usually constructed at the location where historical relic sites are unearthed and are often characterized by large-space building layouts and high energy consumption for the environmental control. However, the traditional strategies for environmental control are limited in protecting the unearthed relics from desiccation cracking and salt concentration. In this study, an environmental control strategy of evaporative cooling system is proposed as a solution to develop a sustainable preservation environment to maintain the condition of the ancient relics at a state of moist saturation. Afterwards, a verification of sustainability and climate suitability analysis of the proposed system were conducted. The results indicate that (1) the evaporative cooling system can fulfil the high humidity preservation environment requirements for the unearthed historical relic sites with a low energy consumption; and (2) the potential use of the evaporative cooling systems is significant in Xi’an and Chengdu (i.e., being 62% and 75%, respectively), and not in Lanzhou and Urumqi. As a conclusion, the proposed strategy provides a sustainable protocol for the preservation of unearthed historical relic sites in archaeological museum.

Purpose Based on dual organizational theory, the purpose of this paper is to examine the relationship between transformational leadership and innovative behavior in groups. The authors proposed that group innovative behavior was influenced by transformational leadership as a group-level construct which was moderated by dual organizational change that represent organization-level resources. Furthermore, the authors identified two organizational change-related situational variables-radical change and incremental change and examined their effects on group innovative behavior. Design/methodology/approach The authors collected data from full-time employees working in groups in 43 companies, located in five cities in China including Beijing, Yantai, Chengdu, Xi’an, and Chengde. These enterprises were from a wide range of industries, including manufacturing, financing, information technology, and geological exploration. The authors chose a middle- or senior-level manager from each company to act as chief survey respondent, who were asked to contact managers and employees from a list they had provided and invite them to participate in a web-based survey (via an e-mailed link) or a paper-and-pencil survey. A total of 192 managers and 756 direct subordinates from 112 groups completed the survey. Findings Results found that transformational leadership was positively related to group innovative behavior, and this relationship was moderated by radical change, but not incremental change; radical change and incremental change were also positively related to group innovative behavior. Research limitations/implications This study adopts a cross-sectional study design, which is insufficient for deriving causal inferences. Future research may adopt a longitudinal study design to investigate causal impacts. Besides, some unmeasured variables could be related to transformational leadership and innovative behavior. Practical implications The paper includes implications for adopting appropriate leadership style to motivate innovative behavior, promoting dual organizational change to boost innovative behavior, and generating greater innovative behavior for transformational leaders in times of radical change. Originality/value This cross-level study contributes to the relationship between transformational leadership and group innovative behavior in the context of dual organizational change.

The study aims to examine the major atmospheric air pollutants such as NO2, CO, O3, PM2.5, PM10, and SO2 to assess the overall air quality using air quality zonal modeling of 15 major cities of China before and after the COVID-19 pandemic period. The spatio-temporal changes in NO2 and other atmospheric pollutants exhibited enormous reduction due to the imposition of a nationwide lockdown. The present study used a 10-day as well as 60-day tropospheric column time-average map of NO2 with spatial resolution 0.25 × 0.25° obtained from the Global Modeling and Assimilation Office, NASA. The air quality zonal model was employed to assess the total NO2 load and its change during the pandemic period for each specific region. Ground surface monitoring data for CO, NO2, O3, PM10, PM2.5, and SO2 including Air Quality Index (AQI) were collected from the Ministry of Environmental Protection of China (MEPC). The results from both datasets demonstrated that NO2 has drastically dropped in all the major cities across China. The concentration of CO, PM10, PM2.5, and SO2 demonstrated a decreasing trend whereas the concentration of O3 increased substantially in all cities after the lockdown effect as observed from real-time monitoring data. Because of the complete shutdown of all industrial activities and vehicular movements, the atmosphere experienced a lower concentration of major pollutants that improves the overall air quality. The regulation of anthropogenic activities due to the COVID-19 pandemic has not only contained the spread of the virus but also facilitated the improvement of the overall air quality. Guangzhou (43%), Harbin (42%), Jinan (33%), and Chengdu (32%) have experienced maximum air quality improving rates, whereas Anshan (7%), Lanzhou (17%), and Xian (25%) exhibited less improved AQI among 15 cities of China during the study period. The government needs to establish an environmental policy framework involving central, provincial, and local governments with stringent laws for environmental protection.

The associations between children’s pocket money and their eating behaviors and weight status have not been examined using longitudinal data in China. Examined child and parental factors associated with children’s pocket money, and longitudinal effects of pocket money on children’s eating behaviors and weight status. Data were collected in 2015, 2016, and 2017 from 3261 school-age children and their parents in mega-cities across China (Beijing, Shanghai, Nanjing, Xi’an, Chengdu). Children’s weight, height, and waist circumference were measured; pocket money and eating behaviors were self-reported. Mixed effect models were used. Older children received more pocket money than younger children (incident rate ratio (IRR) = 1.21, 95% confidence interval (CI): 1.15, 1.26). Fathers gave their children more pocket money than mothers did (IRR = 1.22, 95% CI: 1.16, 1.30). Children with fathers having ≥ college education received more pocket money than the others did (IRR = 1.20, 95% CI: 1.04, 1.40). Some nutrition-related parenting behaviors and attitude were also associated with children’s pocket money. Compared with children receiving no weekly pocket money, those having 1–10 or 10–30 or >30-yuan weekly pocket money were 12.0–136% more likely to consume unhealthy foods and were 66–132% more likely to be overweight or obese. Some child and parental factors were associated with children’s pocket money, which increased risks of having unhealthy eating behaviors and being overweight and obese.

A severe haze pollution incident caused by unfavorable weather conditions and a northern air mass occurred in eastern, northern, northwestern, and southwestern China from January 15 to January 22, 2018. To comparatively analyze variations in PM2.5 pollution, hourly monitoring data and 24 h meteorological data were collected. Air quality observations revealed large spatiotemporal variation in PM2.5 concentrations in Handan, Zhengzhou, Xi’an, Yuncheng, Chengdu, Xiangyang, and Jinan. The daily mean PM2.5 concentrations ranged from 111.35 to 227.23 μg·m−³, with concentration being highest in Zhengzhou. Hourly mean PM2.5 concentration presented multiple U-shaped curves, with higher values at night and lower values during the day. The ratios of PM2.5 to PM10 were large in target cities and the results of multiscale geographic weighted regression model (MGWR) and Pearson correlation coefficients showed that PM2.5 had a significant positive or negative correlation with PM10, CO, NO2, and SO2. The concentration of PM2.5 was closely related to the combustion of fossil fuels and other organic compounds, indicating the large contribution of secondary aerosols to PM2.5 concentrations. The analysis of meteorological conditions showed that low temperature, low wind speed, and high relative humidity could aggravate the accumulation of regional pollutants in winter. Northwestern trajectory clusters were predominant contributions except in Jinan, and the highest PM2.5 concentrations in target cities were associated with short trajectory clusters in winter. The potential sources calculated by Weight Potential Source Contribution Function (WPSCF) and Weight Concentration-Weighted Trajectory (WCWT) models were similar and the highest values of the WPSCF (>0.5) and the WCWT (>100 μg·m−³) were mainly distributed in densely populated, industrial, arid, and semiarid regions.

Full textAbstract:
As an economic pillar, major resource consumer, and polluter of cities, the chemical industry determines many cities’ transformation, prosperity, and decay. It is thus a major concern for achieving the UN Sustainable Development Goals. In China, which is at the stage of accelerated industrialization that is varied across regions, the chemical industry has gradually retreated from developed cities, such as Beijing and Shanghai, in the eastern region, and has become the inevitable choice for industrialization of less-developed cities, such as Xi’an, Chengdu, and Chongqing, in the western region. This study took the perspectives of chemical industrial sectors and their spatial differences to understand the changing patterns of the chemical industry and its dominant cities. It identified chemical industrial cities (CICs), examined their spatial-temporal patterns with respect to their industry scale and structure, and accounted for factors influencing the spatial evolution from coastal areas to inland regions. The results show that large CICs were mainly located in coastal port regions with balanced industrial sectors, while small CICs were mainly distributed in inland areas with abundant oil and coal resources and a single dominant industrial sector. The location factors of ports, markets, and technology play important roles in the eastern region, while resource conditions and foreign direct investment promote the chemical industry’s development in the central, western, and northeastern cities. These findings improve the understanding of CICs’ spatial transformation and shed light on the policy-making of chemical industrial development in China and other developing countries.

Full textAbstract:
More and more tourists tend to seek cultural enjoyment while taking trips based on their satisfied socio-economic needs. The spatiality of cultural tourism determines the feasibility and convenience of the access to cultural tourism resources. Given that spatial research on cultural tourism rarely involves the underdeveloped regions in China, especially via Baidu Index data, this study aims to explore the dynamic spatial pattern of cultural tourism Internet attention based on Baidu Index through social network analysis (i.e., network density, centrality analysis, core–periphery model, etc.) in the Western Triangle Economic Zone (WTEZ), China. Research findings are as follows. (1) Temporally, the centrality is increasingly enhanced in terms of the core cities with high cultural tourism Internet attention, as well as their radiation effect. (2) Spatially, the distribution pattern of cultural tourism Internet attention is shifting from polarization to equilibrium. However, the overall network density still presents a mode of loose connection and fails to extend from the core triangle structure in the planar dimension. (3) The cultural tourism Internet attention in WTEZ presents an obvious core–periphery pattern. Xi’an–Chengdu–Chongqing is in a dominant position, and the core area spreads from south to north. (4) The spatial-temporal pattern of cultural tourism Internet attention in WTEZ is influenced by transportation, reception facilities, consumption ability, and political environment, and the main driving factors are the number of hotels, per capita income, total highway mileage, and cultural tourism policy indicators. This study is conducive to sustainable spatial planning of cultural tourism through smart data governance.

Full textAbstract:
The current geological sketch in tunnel engineering is mainly based on sketches of workers. However, geological sketch drawn by workers always offers fundamental data purely due to its drawing mode. A novel drawing method for geological sketch has been introduced using multiview photos in this process. The images of tunnel faces are taken from multiple angles, and every two pictures have overlaps. By measuring the distance between the camera and the tunnel face using a laser range finder, the photographic scale of each photo can be confirmed. SpeededUp Robust Features (SURF) is a good practice for detecting feature points, and the sparse point cloud is reconstructed from multiview photos by structure from motion (SFM). However, the sparse point cloud is not suitable for analysis for structural planes due to its sparsity. Therefore, patch-based multiview stereo (PMVS) is used to reconstruct dense point cloud from the sparse point cloud. After 3D reconstruction, the details of the tunnel face are recorded. The proposed technique was applied to multiview photos acquired in the Xiaosanxia railway tunnel and Fengjie tunnel in Chongqing, China. In order to record the geological conditions of the tunnel face quickly and accurately, Chengdu Tianyou Tunnelkey has developed a set of software and hardware integration system called CameraPad. Besides, CameraPad was used to collect the multiview photos of the tunnel face in the No. 1 Xinan railway tunnel in Jilin, China. By comparing with traditional and existing methods, the proposed method offers a more reductive model for geological conditions of the tunnel face.

Abstract. The spatial distribution of the aerosols over 86 Chinese cities was reconstructed from air pollution index (API) records for summer 2000 to winter 2006. PM10 (particulate matter ≤10 μm) mass concentrations were calculated for days when PM10 was the principal pollutant, these accounted for 91.6% of the total 150 428 recorded days. The 83 cities in mid-eastern China (100° E to 130° E) were separated into three latitudinal zones using natural landscape features as boundaries. Areas with high PM10 level in northern China (127 to 192 μg m−3) included Urumchi, Lanzhou-Xining, Weinan-Xi'an, Taiyuan-Datong-Yangquan-Changzhi, Pingdingshan-Kaifeng, Beijing-Tianjin-Shijiazhuang, Jinan, and Shenyang-Anshan-Fushun; in the middle zone, high PM10 (119–147 μg m−3) occurred at Chongqing-Chengdu-Luzhou, Changsha-Wuhan, and Nanjing-Hangzhou; in the southern zone, only four cities (Qujing, Guiyang, Guangzhou and Shaoguan) showed PM10 concentration >80 μg m−3. The median PM10 concentration decreased from 108 μg m−3 for the northern cities to 95 μg m−3 and 55 μg m−3 for the middle and southern zones, respectively. PM10 concentration and the APIs both exhibited wintertime maxima, summertime minima, and the second highest values in spring. PM10showed evidence for a decreasing trend for the northern cities while in the other zones urban PM10 levels fluctuated, but showed no obvious change over time. The spatial distribution of PM10 was compared with the emissions, and the relationship between the surface PM10 concentration and the aerosol optical depth (AOD) was also discussed.

Abstract. A multi-lidar system, mounted in a vehicle to monitor the profiles of temperature, wind, and particle optical properties, was utilized to investigate the winter fine particulate matter (PM2.5) pollution from a vertical perspective in four cities in China in winter 2018. We observed the enhancement of surface nocturnal PM2.5 in two typical plains cities (Changzhou and Wangdu), which was attributed to the subsidence of PM2.5 transported from upstream polluted areas, with the wind turning north and downdrafts dominating. Combining the observed surface PM2.5, the reanalysis meteorological data, and the GEOS-Chem model simulation, we revealed the transport nocturnal PM2.5 enhancement by subsidence (T-NPES) events that occurred frequently in the two cities, with percentages of 12.2 % and 18.0 %, respectively, during December 2018–February 2019. Furthermore, the GEOS-Chem model simulation further confirmed the ubiquity of winter T-NPES events on a large scale, including North China Plain and the Yangtze River Delta. Process analysis revealed that the subsidence was closely correlated with the southeasterly movement of the high-pressure system and the passage of the cold front, resulting in the increase of temperature aloft, a stronger inversion layer, and further PM2.5 accumulation in the atmospheric boundary layer. Thus, a conceptual model of the T-NPES events was proposed to highlight this surface PM2.5 enhancement mechanism in these plains regions. However, it did not apply to the two cities in the basin region (Xi'an and Chengdu) due to the obstruction of the weather system movement by the mountains surrounding the basin.

Full textAbstract:
Under the impact of financial technology and digital currency, “central bank digital currency” has become an international hotspot in recent years and is also one of the current research and development priorities of China’s central bank. Preparations for China’s digital RMB began as early as 2014, and in 2017 China’s central bank clearly announced that it would fully issue the digital currency. The launch of the digital RMB is a major reform and innovation in the historical development of China’s currency. China’s issuance of a central bankdigital currency will help enhance the status of the People’s Bank, strengthen the effectiveness of monetary policy, improve macro-prudential management capabilities, and promote cross-border RMB payments, etc. Up to now, China has started pilot tests in some cities, such as Shenzhen, Xian, Chengdu Suzhou. Currently, China’s digital RMB has been tested for the public, with features such as unlimited legal compensation, moderate anonymity, national statutory, dual offline payment, no cost of transaction and centralized management. With the rapid development of scientific information technology and the intensification of international competition, the digitalization of currency has become an irreversible trend. The purpose of this study is to identify the practice of digital Yuan and its role in Chinese digital economy development. The discussion tasks of this paper can be summarized as follows. Clarify the definition of digital Yuan; assess the operational model of digital Yuan; evaluate the operating framework of digital Yuan; identify the features and merits of digital Yuan application. This research adopts case study of China CBDC and literature analysis methods to analyzed the concept, characteristics and design principles of digital RMB. Then it investigates the role of digital RMB for the development of China’s digital economy, which will provide an important basis for understanding and advancing the domestic research on the central bank’s digital currency. For example, digital Yuan plays a key role in facilitating data productivity, driving digitalization of public payment scenarios and opening a healthy digital economy system.

Full textAbstract:
Accurately mapping urban built-up areas is critical for monitoring urbanization and development. Previous studies have shown that Night light (NTL) data is effective in characterizing the extent of human activity. But its inherently low spatial resolution and saturation effect limit its application in the construction of urban built-up extraction. In this study, we developed a new index called VNRT (Vegetation, Nighttime Light, Road, and Temperature) to address these challenges and improve the accuracy of built-up area extraction. The VNRT index is the first to fuse the Normalized Difference Vegetation Index (NDVI), NPP-VIIRS Nighttime NTL data, road density data, and land surface temperature (LST) through factor multiplication. To verify the good performance of VNRT in extracting built-up areas, the built-up area ranges of four national central cities in China (Chengdu, Wuhan, Xi’an, and Zhengzhou) in 2019 are extracted by the local optimum thresholding method and compared with the actual validation points. The results show that the spatial distribution of VNRT is highly consistent with the actual built-up area. THE VNRT increases the variability between urban built-up areas and non-built-up areas, and can effectively distinguish some types of land cover that are easily ignored in previous urban indices, such as urban parks and water bodies. The VNRT index had the highest Accuracy (0.97), F1-score (0.94), Kappa coefficient (0.80), and overall accuracy (92%) compared to the two proposed urban indices. Therefore, the VNRT index could improve the identification of urban built-up areas and be an effective tool for long-term monitoring of regional-scale urbanization.

ObjectivesThis study explored the relationship between self-management and blood pressure (BP) control in China.DesignA cross-sectional study.SettingEight community health centres from four cities in the Northeast (Shenyang), Northwest (Xi’an), Southwest (Chengdu) and South (Changsha) of China.ParticipantsA total of 873 adults with hypertension, including 360 men and 513 women. Hypertension was defined as systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg.Outcome measurementsBP control was the primary outcome variable. This was categorised as good control if individuals with hypertension reduced their BP to <140/90 mm Hg, otherwise, it was categorised as poor control. Secondary outcomes included self-management, defined as: (1) context or condition-specific factors or physical/social environments (eg, age, sex, marital status, education, personal income and health insurance) and (2) process or knowledge/beliefs, self-regulation skills/abilities and social facilitation (eg, treatment, diet, exercise and risk factor management). Data were analysed using logistic regression models using SPSS V.20.ResultsA total of 67.1% (n=586) participants had poor BP control. Limited outpatient care benefits in mainly rural residents (OR 2.26, 95% CI 1.06 to 4.81) and longer disease duration (OR 1.03, 95% CI 1.01 to 1.04) were associated with poor BP control. Self-management practices reduced the odds of having poor BP control (OR 0.98, 95% CI 0.97 to 0.99).ConclusionsThe individual and family self-management theory can serve as an effective theory for understanding the key contexts, processes and outcomes essential for BP control in China. Future research should evaluate the effect of a self-management intervention (eg, self-monitoring, medication adherence, regular and routine doctor visits, and social supports) for BP control in China using a multisite cluster randomised controlled trial. Sex and gender difference, cost and patient-reported outcomes should also be examined.

Purpose – The aim of this study is to explore the mediating role of executive competency in entrepreneurial-orientated corporations between entrepreneurial orientation and corporate performance. Design/methodology/approach – The authors conducted a survey of entrepreneurial-oriented enterprises mainly located in Beijing, Shanghai, Hangzhou, Shenyang, Dalian, Anshan, Chengdu, Guiyang, Wuhan, Taiyuan, Xi’an, Guangzhou, Shenzhen and so on, areas which cover North China, northeast of China, Yangtze River Delta and Pearl River Delta, and are largely representative of the population as a whole. A total of 300 questionnaires were issued with 276 returns, a response rate of 92 per cent; 248 of these were valid. Findings – First, executive competency in entrepreneurial-oriented corporations has four dimensions. These are profession features, concept features, interpersonal features and individual internal drive features; 15 competency elements are included in the above dimensions. Second, entrepreneurial orientation does improve corporate performance, and the positive influence is mainly through two dimensions, which are innovation and antecedence. Third, executive competency has a positive influence on corporate performance, thus confirming the effectiveness of executive competency as a dependent variable. Finally, executive competency has a partial mediating influence on the relationship between entrepreneurial orientation and corporate performance, with a full mediating influence on innovation and corporate performance, and a partial mediating influence on antecedence and corporate performance. Originality/value – The conclusions have important implications. Theoretically, the executive competency model, which fits entrepreneurial orientation, is constructed, and the relationship between entrepreneurial orientation and corporate performance is enriched and extended to include executive competency, which provides a theoretical foundation and empirical support for understanding and explaining entrepreneurial strategy in Chinese corporations. In terms of practical implications, this study helps entrepreneurial-orientated corporations to develop a proper human resources management system to recruit, evaluate, train and develop executives, resulting in continuous performance improvement.

Full textAbstract:
Green plants provide food, energy and oxygen sources for human beings and animals on Earth through photosynthesis, which is essential to maintain regional ecological balance. However, few studies have focused on the natural oxygen supply capacity of urban green spaces. As a companion to photosynthesis in leaves, solar-induced chlorophyll fluorescence (SIF) contains abundant photosynthetic information. Currently, satellite-based SIF observations are considered to be a rapid and nondestructive ‘indicator’ of plant photosynthesis, which provides an alternative way to quantitatively assess the spatio-temporal dynamics of oxygen supply capacity in urban green spaces. This study examined the spatial patterns, long-term trends, and environmental control factors of SIF in the nine central cities in China from 2001 to 2020 based on the time-series of the global reconstructed GOSIF-v2 SIF dataset. The results were as follows: (1) There was a contrasting spatial difference between southern and northern cities in China, and multi-year mean SIF values of the southern cities were generally higher than those of the northern cities; (2) The interannual dynamics of SIF in each city generally showed an upward trend, with fluctuations, and the intraannual seasonal differences were more significant in northern cities than those in the southern cities; (3) The spatial trend analysis showed that Beijing, Guangzhou, and Chongqing have had the most significant improvements, followed by Xi’an, Wuhan, Chengdu, and Zhengzhou, while Tianjin and Shanghai have had the least improvements; and (4) The expansion of construction land has exerted significant impacts on the dynamics of the SIF trend in several cities, but it is not the only factor. All analyses indicated that the improvement of vegetation structure and function in the area can offset its negative effect.

Abstract. Brown carbon (BrC) constitutes a large fraction of organic carbon and exhibits strong light absorption properties, thus affecting the global radiation budget. In this study, we investigated the light absorption properties, chemical functional bonds, and sources of BrC in six megacities in China, namely Beijing, Harbin, Xi'an, Chengdu, Guangzhou, and Wuhan. The average values of the BrC light absorption coefficient and the mass absorption efficiency at 365 nm in northern cities were higher than those in southern cities by 2.5 and 1.8 times, respectively, demonstrating the abundance of BrC present in northern China's megacities. Fourier transform infrared (FT-IR) spectra revealed sharp and intense peaks at 1640, 1458–1385, and 1090–1030 cm−1, which were ascribed to aromatic phenols, confirming the contribution of primary emission sources (e.g., biomass burning and coal combustion) to BrC. In addition, we noted peaks at 860, 1280–1260, and 1640 cm−1, which were attributed to organonitrate and oxygenated phenolic groups, indicating that secondary BrC also existed in the six megacities. Positive matrix factorization (PMF) coupled with multilayer perceptron (MLP) neural network analysis was used to apportion the sources of BrC light absorption. The results showed that primary emissions (e.g., biomass burning, tailpipe emissions, and coal combustion) made a major contribution to BrC in the six megacities. However, secondary formation processes made a greater contribution to light absorption in the southern cities (17.9 %–21.2 %) than in the northern cities (2.1 %–10.2 %). These results can provide a basis for the more effective control of BrC to reduce its impacts on regional climates and human health.

Abstract. The spatial distribution of the aerosols over 86 major Chinese cities was constructed from 137 845 daily averaged PM10 (particles with diameter ≤10 μm) concentrations calculated from air pollution index (API) records spanning from summer 2000 to winter 2006. This dataset was based on days when PM10 was categorized as the principal pollutant, accounting for 91.6% of the total recorded days. The 83 cities in mid-eastern China (longitude 100° E to 130° E) were separated into three latitudinal zones with the Qinlin Mountain – the Huaihe River and the Yunnan-Guizhou Plateau – the Jiangnan Hill – the Wuyi Mountain as the boundaries. The spatial distribution of PM10 was complicated; the high-value spots in northern China (concentration ranged from 127.1 to 192.1 μg m−3) included Urumchi, Lanzhou-Xining, Weinan-Xi'an, Taiyuan-Datong-Yangquan-Changzhi, Pingdingshan-Kaifeng, Beijing-Tianjin-Shijiazhuang, Jinan, and Shenyang-Anshan-Fushun; in the middle zone, the high PM10 spots (concentration within 119.1–146.6 μg m−3) were Chongqing-Chengdu-Luzhou, Changsha-Wuhan, and Nanjing-Hangzhou; while in the southern zone, four cities (Qujing, Guiyang, Guangzhou and Shaoguan) showed higher PM10 concentration (>80 μg m−3). An overall latitudinal gradient was distinct; the median PM10 concentrations decreased from 108 μg m−3 for the 38 northern cities to 95 μg m−3 and 55 μg m−3 for the middle (26 cities) and southern (19 cities) zones, respectively. Linear regression between PM10 concentration and latitude of the cities also confirmed this gradient. PM10 concentration and the APIs exhibited similar seasonality with wintertime maxima and summertime minima, and the second highest values in spring. PM10 level showed a decreasing trend (−23.2 μg m−3) for the northern cities during 2000 to 2006. For the other two zones, the PM10 levels fluctuated, but showed unobvious change (−1.7 μg m−3) for the middle zone and increased slightly (+6.2 μg m−3) for the southern zone during the course.

AbstractUnderstanding heat‐related impacts is crucial to improving public awareness of addressing urban heat challenges and enabling decision makers to mainstream heat action plans. This study explores heat‐related physiological and psychological impacts, symptoms, and demographic determinants based on 4210 questionnaires across nine large Chinese cities, including Chengdu, Chongqing, Guangzhou, Hangzhou, Nanchang, Nanjing, Shanghai, Shenyang, and Xi'an in August 2020. The results indicate that heat‐related psychological impacts are equally severe as physiological impacts. Chongqing is under the most severe heat‐related health impact on both the physiological and psychological aspects. Skin heat damage (SKI), digestive system illnesses (DIG), respiratory illnesses (RES), and cardiovascular illnesses (CAR) are prominent physiological illnesses in all cities, while emotional irritability (EMO), easy to lose control temper (EAS), low mood (LOW), and insomnia (INS) are prominent psychological symptoms. Chongqing and Guangzhou are the most vulnerable cities in terms of physiological and psychological symptoms. Chengdu, Hangzhou, Nanjing, and Shanghai are more resilient in terms of physiological symptoms, whereas Chengdu, Hangzhou, and Shanghai are more resistant to psychological symptoms. Heat‐related health impacts, symptoms, and demographic determinants are spatially heterogeneous. The elderly and patients are more vulnerable, while such a conclusion is not always true. The spatial heterogeneity of heat‐related physiological and psychological impacts, symptoms, and drivers highlights the significance of developing city‐specific heat health action plans.

Abstract Objectives This study examined Chinese children's self-perceived and measured weight status, the main and interaction effects of children's self-perceived weight status and lifestyle behaviors on changes in their body mass index (BMI) over 3 years. Methods Children's weight, height, self-perceived weight status, and lifestyle behaviors (food intake, sedentary behavior, off-campus physical activity) were measured for 3298 children aged 6–18 years in Beijing, Shanghai, Xian, Nanjing, and Chengdu across China in 2015, 2016 and 2017. This analysis included the 1691 children who had >= two repeated BMI measurements during 2015–2017. Results The self-perceived weight status of half (49.9% of boys’ and 51.3% of girls’) was consistent with that based on measured weight and height; 45.2% of boys and 29.8% of girls underestimated their weight status. Boys were more likely to self-perceive as having a normal weight even when being obese. In longitudinal analysis, self-perceived weight status was positively associated with BMI among children (β = 4.99, P < 0.01), however, neither the lifestyle behaviors were significantly associated with BMI. Significant interactions between self-perceived weight status and lifestyle behaviors were only found among girls, not in boys. Additive interaction between self-perceived weight status and off-campus physical activity was statistically significant in girls (attributable proportion (95%CI) = 0.404 (0.143,0.666)). Conclusions In China, it is common children underestimated their own weight status. This leads to subsequent increased BMI. Off-campus physical activity could moderate the association. Future interventions are needed to empower children to have accurate assessment of their weight status and to promote physical activity.

Abstract Objectives This study examined: 1) prevalence of overweight and obesity (ov/ob) in children and maternal perception of children's ideal body image in China, 2) associations between maternal perception of children's ideal body image and changes in children's body mass index (BMI) over 3 years. Methods The Children Obesity Study in China Mega-cities is a NIH-funded cohort study and includes Beijing, Shanghai, Xian, Nanjing and Chengdu across China. Data have been collected from school children, their parents and school in 2015 to 2017 (3298 children). Maternal perception of ideal body image of children, child lifestyle behaviors were assessed using questionnaires; child weight and height were measured in schools. The longitudinal analysis included 1691 children (had >= two BMI measurements) aged 6–18 years. Results More boys than girls were overweight or obese (40.6% vs 25.1%). Parents reported very different preferred body shape for boys vs girls (based on sex-specific 8-silhouette body shapes: we grouped 1–4 as thin, 4–5 as normal, 6–8 as overweight). Parents were about 3 times more likely to select ‘overweight’ ones as ideal for boys than for girls (4.3% vs 1.5%). In longitudinal analysis, compared with boys whose parents selected ‘normal weight’ as ideal at baseline, boys whose parents selected ‘overweight’ as ideal were 4 times more likely to develop obesity: OR(95%CI) = 4.06 (2.18,9.03), and they increased their BMI (kg/m2) β (95%CI) = 2.48(1.60–3.36). Girls whose parents selected ‘thin’ as ideal their BMI decreased during the follow-up than girls whose parents selected ‘normal weight’ as ideal: β (95%CI) = −0.46(−0.80, −0.11). Conclusions Chinese parents preferred heavier body shape for boys and thinness for girls. This has contributed to the much higher overweight/obesity rates in boys than girls in China. Parents’ ideal body image regarding their children affects their children's weight change. Funding Sources The US National Institutes of Health (NIH U54HD070725).

"Reflexive Han-Ness, Narratives of Moral Decline, Manchurian Subjects and “Mass” Societal Others: A Study of the Hanfu Movement in the Cities of Beijing, Chengdu, Shanghai, Wuhan, and Xi’an." Journal of Current Chinese Affairs, November 17, 2022, 186810262211350. http://dx.doi.org/10.1177/18681026221135082.
Full textAbstract:
In recent years, a small but growing body of scholarly work has emerged on the Hanfu movement in China. Researchers have drawn attention to globalisation, westernisation, national lifestyles, and development, the renaissance of Chinese culture, Han racism, Han ethnocentrism and xenophobia as drivers for the movement. In this article, we suggest that of all the extant literature that currently exists on the movement, the ethnography conducted by Kevin Carrico is the most accurate portrayal of the movement as it stands. However, and drawing upon visual and interview-based fieldwork with members of the movement in 2013 and 2015, our main argument is that existing scholarship has not attended to several nuances in the movement that problematise ideas of race, the way the movement views the recent past and the othering of Manchurian subjects. Unpacking these problematics, this study advances upon existing scholarship: 1) by drawing attention to the way Hanfu enthusiasts demonstrate a great deal of reflexivity around the notion of race; 2) by focusing on the approaches by which Hanfuists interpret the Chinese past beyond narratives of Han ethnic decline; 3) by investigating the mode by which Hanfuists indirectly “other” Manchurian subjects; and 4) by exploring the manner in which Hanfuists hold a broad or “mass” societal “other” as responsible for a new era of moral decline in contemporary China.

Full textAbstract:
Global climate change has intensified the water cycle, leading to frequent extreme precipitation events, posing a significant threat to railway infrastructure and safety operations. Based on the analysis of past and future precipitation changes in China, this study investigates the impact of climate change on railway safety operations. The study reveals the following findings: (1) Under the influence of the intensified East Asian summer monsoon and the northward shift of the subtropical high during the 2017–2021 compared to the 2012–2016, precipitation has significantly decreased (120 mm) in the regions south of the Yangtze River and South China, while it has increased (60 mm) in the regions from the eastern of Northwest China to the middle and lower reaches of Yangtze River; The operational precipitation risk has decreased for Urumqi, Lanzhou, Qinghai-Tibet Group, Xi’an, and Wuhan railway bureaus (abbreviated as Bureau), while it has increased for Nanchang, Chengdu, Zhengzhou, Shanghai, and Shenyang Bureaus. Particularly noteworthy is that despite a decrease in total annual precipitation for Nanchang bureau (15.3 mm/a), the frequency of intense precipitation events has increased, leading to an increased operational precipitation risk. (2) During the 21st century, under high (SSP5-8.5), medium (SSP2-4.5), and low (SSP1-2.6) forcing scenarios, all projections indicate that most of the China will experience an increasing trend in precipitation, with significant increases in precipitation observed in the regions south of the Yangtze Rive, South and Southwest China. The higher the greenhouse gas emissions, the more pronounced the increasing trend in precipitation. (3) Compared to the 20th century, under high (SSP5-8.5), medium (SSP2-4.5), and low (SSP1-2.6) forcing scenarios, all projections indicate that the total annual precipitation hours, railway inspection, speed limit, and closure risk hours have all increased on a national scale during the 21st century. The operational precipitation risk for railways has also increased. The higher the alert level for railway precipitation (precipitation < inspection < speed limit < closure), the higher the proportion of risk hours compared to the 20th century. By the late 21st century, the railway inspection, speed limit, and closure risk hours have increased by 175%, 463%, and 647%, respectively, compared to the 20th century.

Received: 17 January 2024; Revised: 25 January 2024; Accepted: 19 February 2024; Published: 5 March 2024 Abstract: Electrochemical conversion of oxygen-to-hydrogen peroxide (H2O2) through oxygen reduction (ORR) is becoming a green and effective solution to replacing conventional anthraquinone industry. Advanced carbon is currently one of the most promising catalysts for H2O2 electrosynthesis by a selective two-electron ORR (2e-ORR), owing to its chemical and catalytic merits. To realize better performance of 2e-ORR over advanced carbons, extensive efforts is devoted to constructing highly efficient carbon-based active sites, which requests in-depth understanding of their underlying catalytic roles. Here, an informative and critical review of recent investigations on active sites on advanced carbons for 2e-ORR is provided. Together with our recent findings, the review first highlights the promoting progress on heteroatom-doped carbons, and their direct/indirect contributions for 2e-ORR has been emphasized. Simultaneously, defect engineering of carbon scaffold is briefly demonstrated as a practical strategy for achieving outstanding H2O2 production. Meanwhile, the review also offers analysis on striking influence of surface modification for carbon active site. Finally, challenges and perspectives of the advanced carbon catalysts for 2e-ORR are outlined. Such reviewed fundamentals of active sites in this emerging field would shed light to future impactful progress in ORR and broader research of energy and catalysis.

Full textAbstract:
AbstractThe ancient Qin-Shu roads corridor is one of the important cultural main corridors in China. Throughout China’s long historical and cultural evolution, today’s ancestors created a rich intangible cultural heritage along this route. Studying its intangible cultural heritage has important theoretical and practical significance for the protection and innovation of cultural heritage in this region. The purpose of this study is to analyze the spatial and temporal distribution characteristics of intangible cultural heritage along the ancient Qin-Shu roads and explore the main factors affecting its distribution. The nearest neighbor index, kernel density estimation, standard deviation ellipse, location entropy, buffer analysis and other methods were used. The results show that (1) The types of intangible cultural heritage of the ancient Qin-Shu roads are expressed in three echelons. Traditional handicrafts are the most numerous, folk custom and traditional music are the second most numerous, the other categories of ICH are third in quantity overall, among which traditional medicine and sports recreation competition are the scarcest. (2) The overall spatial distribution of intangible cultural heritage along the ancient Qin-Shu roads shows an agglomeration distribution. Its distribution pattern places the central cities (Xi'an, Chengdu and Chongqing) at the core, gradually spreading out and decreasing in density as it reaches peripheral districts and counties. There are significantly differ in the core areas of different types of intangible cultural heritage. (3) In the process of historical development, the intangible cultural heritage of the ancient Qin-Shu roads demonstrated an overall change pattern of “three rising and three falling”. That is, during Qin and Han Dynasties, Sui, Tang and Five Dynasties, and Ming and Qing Dynasties, culture flourished, while in Wei, Jin, Southern and Northern Dynasties, Song and Yuan Dynasties, modern times culture developed slowly. The overall trajectory of the center of gravity of intangible cultural heritage shifted from the northeast to the southwest. (4) Natural and human factors, such as topography, climate, transportation, traditional villages and population evolution, have an important impact on the spatial pattern of the intangible cultural heritage of the ancient Qin-Shu roads. The results of this study provide a useful reference for the theoretical research and practical management of intangible cultural heritage.

The 13th Asia Conference on Mechanical and Aerospace Engineering (ACMAE 2022) was held in Chengdu, Sichuan, China during December 22-24, 2022, following the successful conferences in Nanjing the year before; online in 2020, Bangkok; Thailand in 2019; Singapore in 2018 and Yokohama, Japan in 2017. ACMAE 2022 is sponsored by Sichuan Institute of Electronics, Science and Engineering Institute, co-sponsored by Nanjing University of Science and Technology, Moscow Bauman State Technical University, technically supported by Capitol Technology University, Washington University in St. Louis. This is truly a supported conference on a global scale that few match. However, Since the outbreak of the global covid-19 pandemic, it has been a challenge for the academic community to organize international conferences due to travel restrictions. Considering the safety of the participants, this time we have decided to take the conference online. This international conference was over three-days and provided a forum for discussion of mechanical and aerospace engineering. Submitted papers were received and sent for preliminary and peer review conducted by the technical committees. Professional comments are given according to the aspects of originality, innovation, applicability, technical merit, organizing and writing, relevance to conference. After several rounds of review procedure, some excellent papers have been received to get published in the conference proceedings. The proceedings contains a collection of research papers, organized with 9 chapters: material design and performance simulation, engine modeling and performance optimization, aircraft structure design and control model, control model and reliability analysis in mechanical and electronic systems, space propulsion system and reliability analysis, attitude control and trajectory tracking of UAV and helicopter, aerospace engineering and safety management, power mechanical design and performance measurement, mechanical vibration and mechanical analysis and so on. The conference invited five internationally recognised experts in their fields of mechanical and aerospace engineering to deliver keynote and invite speeches, including Professor Junhui Hu, Nanjing University of Aeronautics and Astronautics, China (Chang-Jiang Distinguished, IAAM Fellow); Professor Naira Hovakimyan, University of llinois, USA (IEEE Fellow); Professor Anbang Sun, Xi’an Jiaotong University, China; Professor Qing Guo, University of Electronic Science and Technology of China, China.
