Cardiovascular disease is the leading cause of death worldwide. Currently, the main goals of clinical treatment are to alleviate symptoms and slow down disease progression. However, there is currently no effective clinical treatment for hereditary cardiovascular diseases caused by genetic mutations. The emergence and application of human pluripotent stem cells (hPSCs) and gene editing have provided immense hope for research and treatment of these diseases. Our team has successfully developed an efficient inducible spCas9 gene editing system in hPSCs, achieving a knockout efficiency of over 90% for the target genes. Additionally, we have also created an efficient inducible base editing system, with an introduction efficiency of over 80% for point mutations. Using this advanced editing system, we have successfully generated a Barth Syndrome hPSCs-CMs model by knocking out the Tafazzin gene. This in vitro cell model accurately recapitulates the severe Ca²⁺ handling abnormalities and impaired contraction force observed in Barth Syndrome patients with arrhythmia and dilated cardiomyopathy in clinical settings. Through our research, we have discovered that the ROS-CaMKII-RYR2 pathway is over-activated in Barth Syndrome hPSCs-CMs. Furthermore, we have successfully restored the disease phenotypes by blocking this pathway. Lastly, we have conducted in vivo gene therapy research using the base editor on transgenic mice with hypertrophic cardiomyopathy and hereditary arrhythmias respectively. This research has allowed us to systematically evaluate the therapeutic efficacy and identify the correlation between efficacy and editing rate. These findings provide crucial theoretical basis and data support for the future clinical translation of gene therapy.

Purpose: The purpose of this study was to extract nano-exosomes from Aloe vera bark callus and validate their effects on collagen synthesis and skin corneous improvement. Methods: Human dermal fibroblast (HDF) was used to validate collagen synthesis, while HaCaT cells, a human keratin cell line, were used to verify absorption capability. The Folin–Denis’s technique was used to determine the polyphenol content. In addition, lotion formulations and skin application experiments were also carried out. Results: Nano-exosomes with size ranging 50–150 nm were successfully isolated from Aloe vera bark callus (alosomes). Alosomes produced 22.11% more collagen in HDF than Aloe vera bark extract at 1.0% concentration. In the cytotoxicity test, 80% of cells were survived at concentrations of 1% or less. After one hour, a considerable quantity was transported into the cytoplasm of HaCaT cells. The polyphenol concentration was four times that of Aloe vera bark extract. Skin tests using alosome-containing lotion demonstrated that skin surface, hydration, and elasticity were improved after 4 weeks. Moisture contents of the stratum corneum and dermis layer were improved, whereas moisture content of corneous was reduced after 4 weeks. Conclusion: The skin-improving effect of nano-exosomes derived from Aloe vera bark callus is shown in this study, indicating its potential as a functional cosmetic raw material.

Polyolefin plastics, such as polyethylene (PE) and polystyrene (PS), are the most widely used synthetic plastics in our daily life. However, the chemical structure of polyolefin plastics is composed of carbon-carbon (C-C) bonds, which is extremely stable and makes polyolefin plastics recalcitrant to degradation. The growing accumulation of plastic waste has caused serious environmental pollution and has become a global environmental concern. In this study, we isolated a unique Raoultella sp. DY₂₄₁₅ strain from petroleum-contaminated soil that can degrade PE and PS film via the high-throughput screening (HTS). Nevertheless, the cooperative interaction of the chemo and bioprocess could achieve the value-addition of these artificial polymers.

Supersonic separation is a clean technology applied in gas processing and treatment. At present, it is mainly used for natural gas liquefaction and dehumidification, and has achieved good results in many natural gas fields. In this technology, the characteristics of cyclone separation, shock wave pressurization, phase transition are concentrated in a separation equipment with compact structure and small volume, called supersonic separator, which is the core equipment of supersonic separation technology. Excitingly, previous investigations have found that Laval nozzles are able to condense CO₂ from power plants into liquids, thereby separating CO₂, which means that these investigations have discovered a potential CO₂ capture approach. Supersonic separation does not require complex membrane materials, nor does it require adsorbents and absorbents. It can spontaneously separate CO₂ from flue gas under the drive of pressure. In addition to the above advantages, supersonic separators also have the advantages of stable operation, small size, low maintenance and operation cost and is a new technology in the field of carbon capture.

Dr. Zhu Huang is associate professor in Xi’an Jiaotong University, he got his doctoral degree from Xi’an Jiaotong University, before he started the postdoctoral research at DAMTP in Cambridge University and CTR in Stanford University.

Community parks play a crucial role in mitigating pollution, carbon emissions and promoting sustainable development in urban areas, since they are a regulatory component of urban ecology. By screening the data of a large number of community parks in Xi'an, Shaanxi Province, China, the study extracted six typical indicators of spatial planform, three-dimensional form, and landscape pattern of green space. It then conducted studies on PM_2.5 reduction (∆_PM2.5) and CO₂ reduction (∆_CO2) in the spring. We explored the effects of the spatial pattern of green spaces on PM_2.5 and CO₂ reduction using Pearson's correlation analysis and linear regression methods, optimizing the extraction of significant correlation indicators and running simulations to analyze the formation and maintenance mechanisms of the microclimate environment in community parks. The results demonstrate that: (1) The area of green space patches, the perimeter of patches, and the area-weighted shape index are significantly and positively connected with ∆_PM2.5& ∆_CO2 among the indicators of green space in various spatial patterns. When the size of green space patches in community parks is between 2 and 3 hm2, the reduction impact is noticeable. (2) In various sized community park green spaces, there is a boundary impact for PM_2.5 and CO₂ reduction, and the boundary distance is positively connected with the patch area. According to the outcomes of the optimization simulation, there is a shared maximum reduction boundary of 264m for PM_2.5 and CO₂ at the most significant reduction effect of 2-3hm2 scale. (3) An overall pattern of enclosed plantings > distributed plantings > row plantings can be seen in the effects of various green space plannings on PM_2.5 and CO₂. (4) There is a positive synergy between the reduction of PM_2.5 and CO₂, particularly as the area grows. The synergistic impact is more pronounced, and the reductions of PM_2.5 and CO₂ both peak at the same distance. The study's conclusions support the sustainable growth of urban green space planning from an urban design perspective and further the concept of green space landscape pattern in urban multi-scale space.

2023第八届教育与创新国际会议

2023年12月8-10日

In order to secure our nation's future, it is essential that our students are equipped with Higher Order Thinking Skills (HOTS) to thrive in the 21st century, excel in the workforce, and compete globally. Science education at the school level plays a critical role in achieving this goal. However, the introduction of HOTS in science education has posed challenges for students. Learning and assessment tasks have become more demanding, leaving many ordinary secondary school students struggling to achieve good grades, let alone excelling in the subject. Consequently, they often feel demotivated and hesitant to pursue higher-level science classes. Despite the implementation of various HOTS teaching and learning strategies over the years, the objective of fostering HOTS in students appears to have fallen short. Unsatisfactory science assessment results, particularly among ordinary secondary school students, indicate an inherent flaw in the current approach. This suggests that while teaching methods have focused on developing HOTS, there has been a neglect of students' acceptance and understanding of these skills. Questions arise regarding the suitability of HOTS techniques for all students, especially those in ordinary schools, who make up the majority. How do students with varying abilities handle HOTS tasks, particularly in the context of science learning and assessment? Dealing with HOTS tasks extends beyond mere thinking; it also encompasses cognitive, autonomic, and EEG activities that influence students' acceptance or rejection of these tasks. As a result, research has been conducted to investigate how ordinary secondary school students respond to science Higher Order Thinking Skills (HOTS) tasks, examining their cognitive, autonomic, and Electroencephalography (EEG) reactions. This research seeks to shed light on the challenges students face in embracing and engaging with HOTS, particularly in the field of science education.

2023第七届建筑与城市规划国际会议

2023年7月22-24日

Modular building is a form of highly integrated prefabricated building. It has been a development direction of industrial buildings owing to its high prefabrication rates, efficient construction, energy saving and environmental protection. Traditional modular reinforced concrete buildings adopt wet connections and bring about several problems, such as long construction period, difficult inspection of connection quality, difficult to remove and reuse, and poor seismic resistance. Therefore, the wet connection has significantly restricted the development of modular buildings. This thesis studies the modular units and its connection forms for modular shear wall structures. A connection joints ease of installation and removal for frame modules is designed, and a modular shear wall system with prefabricated energy dissipation and vibration damping components is proposed. The mechanical properties of frame modules and the seismic performance of the modular shear wall system are also studied. The main work and findings include: Determine the module types and connection methods of modular frame shear wall structure systems. Analyze the mechanical properties and optimize the structural design of the connection joints as well as composite columns of the frame module. Study the seismic performance of modular frame shear wall structure systems. The results show that the modular structure with prefabricated energy dissipation and damping component module can reduce the damage of concrete frame module and shear wall, as well as improve the overall seismic performance and rapid recovery ability, thus ensuring the normal use function of the structure.

2023年7月22-24日

Precisely tailoring the electronic structure and surface chemistry of metal-free covalent triazine frameworks (CTFs) for efficient photoactivation of oxyanions is environmentally desirable but still challenging. Of interest to us in this work was to construct artificial defective accumulation sites into a CTF network (CTF-SDx) to synchronously modulate both thermodynamic (e.g., band structure) and kinetic (e.g., charge separation/transfer/utilization and surface adsorption) behaviors and probe how the transformation affected the subsequent activation mechanism of peroxymonosulfate (PMS). With incorporation of terminal cyano (-CN) groups and boron (B) dopants, the delocalized CTF-SD underwent a narrowed electronic energy gap for increased optical absorption as well as a downshifted valence band position for enhanced oxidation capacity. Moreover, the localized charge accumulation regions induced by the electron-withdrawing -CN groups facilitated the exciton dissociation process, while the adjacent electron-deficient areas enabled strong affinity toward PMS molecules. All these merits impelled the photoactivation reaction with PMS, and a 15-fold enhancement of bisphenol-A (BPA) removal was found in the CTF-SD2/PMS/vis/system compared with the corresponding pristine CTF system. Mechanistic investigations demonstrated that this system decomposed organics primarily through a singlet oxygen-mediated nonradical process, which originated from PMS oxidative activation over photoinduced holes initiated by an electron transfer process, thereby opening a new avenue for designing an efficient PMS activation strategy for the selective oxidation of organic pollutants.

The increase in activity of the two-pore potassium-leak channel Kcnk5b maintains allometric juvenile growth of adult zebrafish appendages. However, it remains unknown how this channel maintains allometric growth and how its bioelectric activity is regulated to scale these anatomical structures. We show the activation of Kcnk5b is sufficient to activate several genes that are part of important development programs. We provide in vivo transplantation evidence that the activation of gene transcription is cell autonomous. We also show that Kcnk5b will induce the expression of different subsets of the tested developmental genes in different cultured mammalian cell lines, which may explain how one electrophysiological stimulus can coordinately regulate the allometric growth of diverse populations of cells in the fin that use different developmental signals. We also provide evidence that the post-translational modification of serine 345 in Kcnk5b by calcineurin regulates channel activity to scale the fin. Thus, we show how an endogenous bioelectric mechanism can be regulated to promote coordinated developmental signaling to generate and scale a vertebrate appendage.

To analyze the relationship between prognosis and immune cell infiltration in non-microsatellite instability high (non-MSI-H) colorectal cancer. Non-MSI-H colorectal cancer patients were enrolled from TCGA database. Clinical characteristics correlated to overall survival (OS) and disease-free survival (DFS) were analyzed by univariate and multivariate analysis. Risk models of OS and DFS were further calculated by stepwise regression analysis. Relationship of immune cell infiltration with tumor TNM stage and OS and DFS was evaluated. Immune signaling pathways of CD4 T cells and macrophages were detected by single-cell sequencing. Differential expression genes (DEGs) were calculated and its corresponding protein expressions were assessed. Non-MSI-H colorectal cancer patients could be classified into a high risk and a low risk group with significantly different OS and DFS. Between the two groups, CD4 T cell infiltration was marked higher in the low risk group, and innate immune cell infiltration (macrophages, mast cells and NK cells) was associated with OS and DFS. Single-cell sequencing indicated that CD4 T cells were suppressive but macrophages were relatively stimulated in tumor microenvironment. CDH8 was determined to be one of the DEGs and its high protein expression was proved by immunohistochemical staining. Furthermore, CDH8 expression was correlated to CD4 T cell and macrophage infiltration as well as OS and DFS in non-MSI-H colorectal cancer patients. So, our study indicated that non-MSI-H colorectal cancer could be classified into different groups according to OS and DFS. Re-stimulating CD4 T cell function and targeting CDH8 of tumor cells might provide a new idea of immunotherapy in the future.

Enterocins are ribosomally synthesized antimicrobial peptides produced by Enterococcus faecalis and they show the characteristics of salt tolerance, high temperature tolerance and easy hydrolysis by protease. Enterocins generally show a better antimicrobial effect against close relative species and they have high specificity for their target bacteria. Therefore, the inhibitory effect of Enterocin on the remnants of specific pathogenic bacteria is of great significance for food safe and regulation of intestinal diseases. In this study, a bacteriocin produced by Ent. faecalis DH9003 that can inhibit common food-borne pathogens were screened from goat milk, and their molecular and biochemical characteristics were analyzed. The molecular of the purified Enterocin Y3 was 2.0kDa by analysis of MALDI-TOF-MS. The novel bacteriocin (termed as Enterocin Y3) possessed antimicrobial abilities to dissolve cell wall membrane, and lead to leakage of content of the cells by observing the scanning electron microscopy and transmission electron microscopy.

2023年7月22-24日

Using a corporate-level dataset of Chinese listed companies, we studied the effect of the performance aspiration gap on stock price crash risk and the moderate effect of marketization and political connection. Our results show that: when the actual performance is below aspiration level, the aspiration gap will prompt managers to take risky behaviors and information manipulation behaviors, which will increase the stock price crash risk. In the two types of risky behaviors, the effect of aspiration gap on stock price crash through illegal risky behaviors is greater. The impact of aspiration loss on stock price crash risk is affected by the degree of marketization and political connection. Marketization and political connection negatively moderate the association between aspiration loss and stock price crash risk. When the actual performance is above aspiration level, managers did not have the motivation to adopt or evade the risk-taking behaviors. The aspiration surplus has no significant impact on stock price crash risk. We introduce the performance aspiration gap into the study of stock price crash risk, enriching and expanding the research on the economic consequences of performance aspiration gap and the affecting factors of stock price crash risk, providing a new explanation for our deepen understanding of the stock price crash risk in China's capital market.

2023年7月22-24日

Previous studies indicate the relationship between digitalization and regional innovation may be influenced by the interplay of innovation elements. We expand on this perspective by developing a configurational model underlying the mechanism of elements fit, in which digitalization empowers regional innovation when it supports an innovation orientation appropriate for economic development and government support. Utilizing the fuzzy-set Qualitative Comparative Analysis of a dataset of 31 provinces in China, we derive configurations for digitalization empowering regional innovation. Results reveal that digitalization can empower regional innovation in underdeveloped and weak government-supported environments by supporting basic research orientation. In developed and government-supported environments, either a high or low level of digitalization is effective for an appropriate innovation orientation. The core argument of this study is that the relationship between digitalization and regional innovation is dependent on the elements fit among innovation resources, environmental contexts, and innovation orientation, contributing to a more rigorous and configurational innovation ecosystem theory.

Target trial emulation, using observational data to emulate a target trial, applies the study design principles of randomized trials to observational studies that aim to estimate the causal inference of intervention studies. The advantage of target trial emulation is that observational data is used to emulate a target trial when it is not appropriate to conduct randomized controlled trials. Target trial emulation can control bias caused by the design of observational studies, and improve the effectiveness of causal inference from observational data. This speech introduces the methodological framework and key methodological points for implementing target trial emulation, and analyzes the feasibility and advantages of the application of target trial emulation in the field of traditional Chinese medicine.

The Corona Virus Disease 2019 (COVID-19) global pandemic is characterized by a large number of people infected and multiple mutations of the virus; the sequelae of COVID-19 with more symptoms and longer duration affect multiple tissues and organs of the human body, with higher rates of anxiety, depression and other neurological problems happened 12 months after discharge from hospital, and with unknown mechanisms of fatigue and muscle weakness. These characteristics make it impossible for the pharmaceutical industry to develop drugs against targets, so it is necessary to seek effective therapies from traditional medicine. Chinese herbal medicine has long been a way for people to eat. Plant food with the same origin of medicine and food, regulates human balance and improves human self-healing ability. Plant food has high nutrition and improves human immunity. Adequate and balanced nutrition is essential for managing infections. The COVID-19 pandemic can lead to greater malnutrition, and studies have found that a plant-based diet for COVID-19 patients aged 65 or older during the pandemic reduces disease severity. Therefore, under the influence of COVID-19 for several years, the value of plant food nutrition in the prevention and control of diseases, especially large-scale infectious diseases, may be widely recognized, and the systemic change from the pharmaceutical industry to plant food nutrition may take place in the future.

Depression is prevalent, costly and a major cause of disability and death worldwide. The onset of depression often occurs early in life, during teen or young adult years. The onset of depression during adolescence is associated with increased risk for Major depression during adulthood, substance dependence, educational underachievement, unemployment, and early parenthood. The most severe consequence of untreated depression is suicide. Suicide is the 2nd leading cause of death among adolescents and has increased by 20% in the past decade. A school-based depression education program developed in 2010 by a team of psychiatrists and psychiatric nurses from The First Affiliated Hospital of Chongqing Medical University, has been implemented in 53 schools throughout the China of Chongqing with over 200,000 high school and university students. Screening for mental health problems in university and middle schools in China, and establishing a basic database of adolescent emotion and suicide information. The study found that depression and anxiety were the most common psychological problems reported by adolescents, and family satisfaction also had a direct impact on the emotional state of adolescents. Among adolescents who had committed suicide or self-harm, the scores of impulsivity and aggression were higher, which were important risk factors for suicide. The suicidality risk assessment model was established based on the mental health questionnaire information and other related information reported by the assessor. The model had a strong discrimination ability and good sensitivity and specificity. The model can provide hierarchical early warning for individuals and populations, and provide important reference for timely intervention. We further fitted the approximate relationship between the risk score of suicidality, and visually presented the approximate relationship as the risk level color scale in the way of gradual color scale for further individual and group warning. Based on the analysis of the mental health status of college students screened and the risk factors of college students with suicide attempts, a "medical-school-family joint mental illness and suicide prevention and intervention model" was established. Campus psychological services and family resources were integrated with local mental health institutions to ensure that students in need can receive timely, professional, targeted and personalized intervention. The rate of reported suicide attempts before intervention was 1.36% in the first year and 0.98% in the second year. Rates of reported suicide attempts have decreased.

Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related deaths across the world. Due to the lack of reliable markers for early HCC detection, most HCC patients are diagnosed in middle/late stages. Liver cancer stem cells (CSCs), which are drivers of liver tumorigenesis, usually emerge in the early HCC stage and are also termed as liver tumor initiation cells (TIC). Liver CSCs contribute to initiation, propagation, and metastasis of HCC and also play a key role in tumor therapy. Taking advantage of online-available data sets, bioinformatic analyses, and experimental confirmation, here we have screened out PRC1 and RACGAP1 as reliable markers for early HCC detection. PRC1 or RACGAP1 knockdown dramatically inhibited the proliferation, migration, and invasion capacities of HCC cells, conferring PRC1 and RACGAP1 as predominant modulators for HCC propagation and metastasis. Moreover, the sphere formation capacity of HCC cells was impaired after PRC1 knockdown, revealing the function of PRC1 as a modulator for liver CSC self-renewal. Furthermore, the inhibitor of PRC1 had same phenotypes as PRC1 knockdown in HCC cells. Altogether, PRC1 and RACGAP1 are identified both as prognosis markers for early HCC detection and therapeutic targets for liver cancer and liver CSCs, adding additional layers for the early prognosis and therapy of HCC.

2023年5月27日

At present, the total number of various types of bridges in China has exceeded 1.2 million, and the problem of bridge collisions is becoming increasingly prominent. The busy riverside and coastal waterways are busy, the bridges are susceptible to ship collisions; the geological conditions of bridges in mountainous areas are more complex, and they are susceptible to the impact of landslides, mudslides, and falling rocks; vehicle collisions on urban bridges are frequent. These have had a negative impact on the safety of the bridge itself and the driving safety on the bridges. This study uses explicit dynamic analysis software LS-DYNA to study the impact effect and protective measures of bridges, and further considers the impact effect on driving safety through BANSYS software. Specifically, in response to the impact of falling rocks on bridges, the impact effects of falling rocks at different impact speeds and locations on the bridge, the dynamic response of the vehicle bridge system, and the protective performance of flexible steel sheds were considered; to address the issue of ship collision with bridges, calculations and analyses are conducted on the interaction between piers and water, the process of ship collision with bridges, and the interaction between vehicles and bridges. As a result, some useful conclusions were drawn and further considerations for future research on bridge impact disaster prevention and control were proposed.

演讲主题：Modeling Weathering Processes of Spilled Oil on the Sea Surface Based on Dynamic Bayesian Network

2023第七届能源，环境与资源国际会议

2023年5月27日

Oil spills pose a serious threat to the ecological environment and human health. When the spilled oil enters seawater, weathering processes such as evaporation, emulsification, sedimentation, biodegradation, photooxidation and dissolution will occur. Weathering processes have high uncertainty and directly affect the spatial distribution and fate of oil spills. Up to now, no stochastic models of weathering process have been developed. This paper presents a stochastic modeling method for weathering process of spilled oil on the sea surface based on dynamic Bayesian network (DBN). The physical equations of evaporation, emulsification, biodegradation, photooxidation and dissolution are converted into DBN, and then all the individual DBNs are integrated to obtain the entire DBN of the weathering process. The developed DBN could intuitively and graphically express the logical relations and conditional probabilities among physical variables. This method is helpful to find out the synergistic influencing mechanism of multi-random variables on the weathering process. Based on the developed DBN model, sensitivity analysis is performed to determine the key parameters affecting each weathering process. Uncertainty analysis is carried out to reveal the possible upper and lower limit values of some physical quantities caused by the weathering process.

演讲主题：A Monthly Distributed Water and Salt Balance Model in Irrigated and Non-irrigated Lands of Arid Irrigation District with Shallow Groundwater Table

2023第七届能源，环境与资源国际会议

2023年5月27日

Water scarcity and soil salinization are two major problems threatening the sustainability of irrigation districts in arid regions with shallow groundwater table. To study water and salt balances in arid irrigation districts, we developed a monthly distributed water and salt balance model for arid irrigation district (DAHMID-S) with shallow groundwater table by integrating models of major hydrological processes and the associated salt transport processes, including irrigation, evapotranspiration, soil water and groundwater and salt balances, drainage of water and salt through ditches, and interior drainage of water and associated dry drainage of salt between irrigated and non-irrigated lands. The model was successfully applied to the Hetao Irrigation District (HID), the largest irrigation district in arid region of China. Results indicate that evapotranspiration is the dominant water consumption component in the HID and accounts for about 95% of the total irrigation and precipitation, while drainage through ditches accounts for 10.5% of the total irrigation. Only 49.4% of the introduced salt is discharged from HID through drainage ditches. Consequently, most parts of the HID are in the state of salt accumulation except the northern Wulate sub-irrigation district, and the problem of salt accumulation is more serious in the western and southern HID with more favorable water use conditions. Dry drainage plays a crucial role in salt balance of both irrigated and non-irrigated lands, which results in desalinization in most irrigated lands while salt accumulation in non-irrigated lands. Appropriate measures should be taken to solve water and salt-related problems to improve the sustainability of the HID. In the western HID, irrigation water diversion should be decreased, and the drainage system should be further improved to decrease the salt accumulation to a lower level. Meanwhile, the irrigation water diversion can be increased in the southeastern HID by planting more corn and wheat. Besides, Irrigation management should be improved to reduce the surface water return flow to increase the groundwater drainage capacity, especially in the southwestern HID.

Nanoscale biomaterials have aroused great interest owing to their high biocompatibility, easy availability, small size and large specific surface area. Starch as an edible, biosafe, and functional biopolymer, has been tailored at nanoscale to be used as functional additives in wastewater treatment, emulsion stabilizer, packaging component, and the delivery of bioactive guests. Nanostarches fabricated in various morphologies including nanosphere, nanorod, nanoworm, nanovesicle, nanopolyhedron, nanoflake, nanonetwork, etc., enable them to have a high reactive action due to structural particularity and green modification. It improves the bioavailability of bioactive guests by different assembly approaches of carrier/guest surface combination, guest@carrier embedment and nanostarch-mediated encapsulation. Nanostarch-based carriers improve the functionality of bioactives both in-vitro and in-vivo. We focus on the merits of starch empowered by nanoscale for delivery system, based on the assembly strategies and corresponding properties of nanostarch-based carrier. Nanostarch effectively captures bioactives on the surface and/or inside core to form tight complexes, which maintains their stability in the human microenvironment. Targeted release of delivery systems is stimulated by the environment conditions based on the complex structure of nanostarch loaded with bioactives.

Polymers with intrinsic microporosity (PIMs) have recently received increasing interest in the fields of gas separation, sensors, catalysts, and so on due to their high microporosity and good solution processibility. However, PIMs with chiral backbones are quite limited, which undoubtedly hindered their applications in many areas such as chiral separation and optoelectronic. Herein, the catalytic enantioselective synthesis of a novel cyclohexyl-fused spirobiindane-based chiral PIM is described. This novel polymer exhibits high intrinsical microporosity (SBET = 796 m² g^-1), solubility, and good film formability. Its macroscopic chirality of twist-bend structure was confirmed by circular dichroism. More interestingly, circularly polarized luminescence (CPL) was observed for the first time in PIMs, also to our best knowledge the first non-conjugated porous CPL polymer, opening the door to explore new research fields of PIM materials, as well as providing new guidance for CPL polymer design.

We have designed a cuttage and film covering multi-functional machine for low tunnels. It is composed of automatic rod feeding device, double inserting device, film covering device and marching device. The working parameters such as insertion spacing and number of insertion frames are set. Through the walking mechanism to complete the fixed distance walking and auxiliary walking straight function. Automatic rod feeding device is used to achieve automatic feeding of the shed rod. Using double inserting device to complete the work of bending and inserting poles. Automatic mulching operation is realized by the mulching device. The field test shows that the machine operates at a maximum speed of 1.2 km/h. The average accuracy rate of navigation line extraction is 96.2%. The success rate of entering the pole was 94.1%. The success rate of inserting frames was 89.3%. The arch mulching rate was 100%, and the film breakage rate was 1.1%. It effectively improves the working efficiency of the cuttage and film covering multi-functional machine for low tunnels and the stability of arches construction.

Using a corporate-level dataset of Chinese listed companies, we studied the effect of the performance aspiration gap on stock price crash risk and the moderate effect of marketization and political connection. Our results show that: when the actual performance is below aspiration level, the aspiration gap will prompt managers to take risky behaviors and information manipulation behaviors, which will increase the stock price crash risk. In the two types of risky behaviors, the effect of aspiration gap on stock price crash through illegal risky behaviors is greater. The impact of aspiration loss on stock price crash risk is affected by the degree of marketization and political connection. Marketization and political connection negatively moderate the association between aspiration loss and stock price crash risk. When the actual performance is above aspiration level, managers did not have the motivation to adopt or evade the risk-taking behaviors. The aspiration surplus has no significant impact on stock price crash risk. We introduce the performance aspiration gap into the study of stock price crash risk, enriching and expanding the research on the economic consequences of performance aspiration gap and the affecting factors of stock price crash risk, providing a new explanation for our deepen understanding of the stock price crash risk in China's capital market.

The banking system is an important part of the modern financial system and an indispensable financial intermediary for the healthy and stable operation of the entire economic system. This paper extends the dynamic stochastic general equilibrium (DSGE) model by machine learning, and constructs monetary policy friction index based on financial news. Then, theoretically analyze how the news-driven monetary policy friction affects the non-performance loans of commercial banks. Further, the monetary policy friction volatility spillover network is constructed by GARCH-BEKK model and complex network. Finally, spatial econometric methods are employed to empirically examine the volatility spillover effect of news-driven monetary policy friction on the non-performance loans. The results show that monetary policy friction has a significant positive spatial effect on the non-performing loan of Chinese commercial banks. This means that the government is supposed to increase information transparency in the transmission of monetary policy to reduce information asymmetry.

Historical and cultural district is one of the important carriers of urban cultural heritage, which carries the cultural memory of a region's traditional history, and is an important area of the city with great historical connotation and cultural value. Find the problem through the evaluation of the public's perception of the space of historical and cultural district containing the characteristics of the Grand Canal. Analyze the process experience and emotional reaction of people in the districts, and find that the main impression of historical and cultural districts is the sense of history, canal culture, traditional buildings and so on, and the format and cultural characteristics of districts are important factors affecting users' evaluation. Explore the different spatial identity tendencies of space users due to the differences in spatial perception, and put forward the corresponding protection and renewal strategies. It is suggested that the power logic should be taken as the leading factor, the sustainable development of districts should be strengthened, and the composite industrial system should be formed to enhance people's spatial identity of historical and cultural districts.

演讲主题：International Law and Ideology

查看更多信息

2023第七届社会科学与人文国际会议

2023年5月25日

At present, the Western scholars put forward a theory of international law based on a division of “democracy” and “authoritarian”. We must pay attention to it. An American law professor, Tom Ginsburg’s recent publications on democracy and international law could be taken as an example. Historical Materialism created by Marx and Engles is primarily applied for a domestic society, and also likely for an international society. The international law was originated from Europe as the capitalism rose with a non-theological ideology. The ideology of “civilized nations” was developed in international law as it expanded globally with the West’s capitalism and colonies. It is the contemporary international law under the Charter of United Nations that all sovereign states are equal. It requires removing any discriminative ideology with a character of exclusiveness dividing the states into two blocks. However, the West’s democratic theory of international law tells us that the Cold War relics still remain. It must be criticized by clarifying the principles and rules of contemporary international law under the Charter of United Nations. Meanwhile, we must introduce a new ideology from the Chinese triple perspectives, i.e., the inclusiveness in accordance with the Charter of United Nations, the universality of rule of law at national and international levels under the United Nations’ relevant documents, and the compatibleness of China’s idea to build a Human Community with a Shared Future, and the two initiatives of global security and development.
