Zhonghai Jiang, Qian Wang, Liangbing Zhou

To accurately predict the temperature field in high-temperature asphalt pavement, this paper analyzed the daily variations in the temperature field within high-temperature asphalt pavement. Both the variation law of air temperature and solar radiation intensity were fitted with a double sine function and quasi-normal distribution function. Furthermore, an empirical prediction model was constructed to determine the pavement’s surface temperature. To carry out theoretical predictions and as the boundary conditions of the temperature field, the asphalt pavement was simplified into a single-layer or a double-layer flat plate structure. Based on the obtained results, the predictions of the model with an exact solution for the temperature field was analyzed. The maximum daily average absolute deviation between the predicted and measured data amounted to 1.24 ℃. These results indicate a high prediction accuracy.

Emotional Transfer Framework of Short Texts in Chinese

Ningjing Gong, Zhiyuan Gong

The emotion analysis technology based on deep learning is widely studied and applied. However, its dependence on large data set makes this technology unable to play a role in small domains with only light data sets. To break the application barrier of this technology, we combine the knowledge in deep learning and cross-domain transfer and put forward the emotional transfer framework of short texts in Chinese. The framework takes the task domain as the target domain and selects the one that has sufficient text data and semantic feature intersection as the source domain. It extracts semantic features from the source domain and transfers them to the target domain to make up for the lack of sufficient data in the target domain. It helps the text emotion analysis task work effectively when there are less data in the target domain. This paper introduces the principle of the framework from four modules: the data preprocessing module, the semantic feature transfer module, the training module for the words order model, and the monitoring module for model innovation. Finally, the experimental results show that The framework is feasible, the model effect is good, and the accuracy of emotion classification is 89.0%. It is better than other methods in recent years.

LPSST: Improved Transformer Based Drainage Pipeline Defect Recognition Algorithm

Pengtao Jia, Muyuan Guo

The health status of underground drainage pipelines affects the normal operation of urban drainage systems, but the current mainstream drainage pipeline defect recognition methods have the problems of poor recognition for small samples and fine-grained target defects, as well as low model generalization. Therefore, this paper proposes an improved semi-supervised transformer network based on local region proposal for drainage pipeline defect recognition (LPSST). The algorithm uses the hierarchical Swin Transformer as the backbone network, and adds a local region proposal module to the shallow network to fully pay attention to local features. Finally, a semi-supervised learning framework is used for intensive training to enhance model generalization. We studied the recognition performance of the algorithm in self-made drainage pipeline defect dataset. Compared with other mainstream algorithms such as Resnet and Efficentnet, LPSST has a recognition accuracy of 92.65% for 4 similar defects such as mismatch and deformation, exceeding 17.25% of the original backbone network. The algorithm verifies the applicability of Transformer architecture for the task of drainage pipeline defect recognition, and investigates the positive impact of semi-supervised learning on deep model training.

Impact of Climate Change on the Density Altitude of Nine Chinese Airports

Ting Xu

The development of civil aviation has an impact on global climate change, and climate change will also affect the operation of civil aviation. In civil aviation, density altitude is a physical quantity used to measure aircraft performance. The higher the density altitude, the worse the aircraft performance and control efficiency. In the present work, ERA-Interim data and the output of 18 global climate models in CMIP6 were used to investigate the impact of climate change on the density altitude of nine airports in China. Historical data show that during the period 1979–2014 the density altitude of these nine airports exhibited an increasing trend, and most increased faster in spring and summer. Kace-1.0-G is the best model to simulate the historical trend of 18 global climate models, and is better than the multi-model ensemble. Using the output results of the Kace-1.0-G model under three different scenarios (SSP2-4.5, SSP3-7.0, and SSP4-8.5), the future projection of the density altitude of the nine Chinese airports in question was studied. Results show that the density altitudes of all nine airports exhibit an increasing trend from 2015 to 2100, and the higher the emission scenario, the greater the increase. Nonetheless, the model predicts that density altitude at most airports will increase faster in the winter, unlike under historical conditions.

Point Cloud Simplification Algorithm Based on Hausdorff Distance and Local Entropy of Average Projection Distance

Shigang Wang, Jiawen He, Hongli Guan

The high precision digital dental model obtained by intraoral optical scanner poses great challenges to processing speed and storage space of computers when performing tasks such as data storage, transmission and management. A simplification algorithm based on Hausdorff distance and local entropy of average projection distance is proposed to meet the practical application requirements of digital impression technology. After the edge points are extracted and the interdental points are sampled, the proposed algorithm used octree structure to segment the remaining points. According to the average Hausdorff distance of all points in each subcube and the average Hausdorff distance of the remaining points, the corresponding obtained evaluation ratio is compared with different thresholds of the multi-level simplification criterion, so as to determine the feature degree of the subcube. The point cloud simplification factor and the local entropy of average projection distance are used to preserve the corresponding number of feature points in the feature subcube. According to the local point cloud distribution, all points in the non-feature subcube can be replaced by a certain number of points closest to the center of all points. The experimental results show that the proposed algorithm can well preserve many detail features of the dental model and effectively avoid the appearance of holes in non-feature regions. The proposed algorithm is superior to other comparison algorithm in terms of simplification effect and simplification error.

Output Performance of Flexible Ecoflex Film Based Triboelectric Nanogeneration during Friction Process

The output performances of triboelectric nanogenerator (TENG) are influenced by several parameters such as contact area, material properties, and surface topography etal. However, the influence of friction process on its output performance is not clear. In this work, a TENG worked in slide mode was prepared by flexible Ecoflex00-30 film and aluminum foil electrode. A test apparatus was designed to study the tribological properties and the corresponding output performance of the Ecoflex00-30 film-aluminum foil friction pair with different load and speed. It was found that the working process can be divided into four stages, namely, running-in, initial wear, stable wear, and severe wear stages. In the running-in stage, the electrical output performance of TENG significantly improved with the extension of the test time due to the accumulation of polymer surface charges and the elastic deformation caused by the electrostatic interaction force. In the initial wear stage, an abrasion microstructure was produced on the polymer surface, resulting in an increase in the contact area and slow growth of the electrical output performance. In the stable wear stage, the contact area further increased during the wearing process, and in the meantime, amount of transfer film formed on the electrode surface, which resulting in a stable electrical output when a dynamic balance is achieved. In the severe wear stage, fatigue wears results in pitting formation on the film surface due to the continuous stress cycle, and the electrical output is significantly reduced with the rapidly reduction of contact area.

Zijuan Wang, Chusheng Wang, Xinrong Liu

The problem of geological disasters caused by rock damage and metamorphism under dry wet cycle is very serious. Studying damage and deterioration effect of rock under periodic dry wet cycle is necessary, the "desiccation-saturatation-drying" process in laboratory is used to simulate the repeated fluctuation of reservoir water level, which is used to study the influence of dry-wet cycle on the mechanical properties and energy mechanism of sandstone, and carries out conventional uniaxial and triaxial compression tests and variable amplitude cyclic loading and unloading compression tests on sandstone under different dry wet cycles. The test results show that the maximum total strain energy decreases logarithmically with the increase of n in the test of sandstone under different dry wet cycle, and the rock sample has irreparable damage under the repeated and alternating action of "water saturation and water loss"; Under the condition of uniaxial cyclic loading and unloading, the cumulative energy consumption ratio increases in the form of quadratic parabola with r. the closer it is to the peak strength, the faster the growth rate is. The energy consumption ratio near the peak strength is about 0.6, which is significantly higher than that of monotonic compression test (0.1 ~ 0.3); At lower confining pressures, the initial dissipated energy and hysteretic energy of the rock sample increase slowly. With the increase in the number of dry wet cycle, the difference between dissipated energy and hysteretic energy increases gradually, the shear strength of rock sample decreases gradually at the post peak stage, the lateral strain develops rapidly, and the confining pressure does negative work, so that total strain energy after peak loading and unloading is lower than the total strain energy at the peak point; The dissipated energy, hysteretic energy and released elastic strain energy develop unsteadily after the peak, and the slope of the curve is much greater than that before the peak.

Research on the Innovation of English Educational Models in Chinese Universities in the Context of Artificial Intelligence

Mengting Yuyi, Ying He

The application of artificial intelligence technology plays an important role in innovating universities’ English educational models. However, given the incomplete understanding of the application mode and concept of artificial intelligence technology by teachers and learners and the imperfect construction of their own artificial intelligence teaching platform, some colleges and universities in China have not fully embraced artificial intelligence educational models. To fully adopt artificial intelligence technology in college English educational innovation, colleges and universities should not only enhance English teachers’ and learners’ understanding and application of artificial intelligence technology, but also should consider adding artificial intelligence factors to the educational evaluation system, and to improve the the development of artificial intelligence platform in English curriculum development.

Multi-objective Optimization of Heterogeneous Liner Fleet Deployment with Shipping Downturn Considerations

Shihao Gong, Zhangchi Sun, Jiabao Zhao — 2022-05-15

This paper considers the optimization problem of fleet deployment during the shipping downturn for liner shipping companies. In the operation of the liner shipping companies, there is a rising trend to deploy a heterogenous fleet on certain route. Especially when the shipping market is depressed, the combination of ships with different carrying capacities (i.e., heterogeneous fleets) can reduce the waste of carrying capacity. The excessive transportation capacity will increase the capital cost and the maintenance cost. Consequently, the reduction of the capacity loss and the minimization of the operation cost of the liner ships are both vital for the liner shipping companies. The problem is formulated into a multi-objective optimization problem. And then an improved non-dominated sorting genetic algorithm-II (NSGA-II) is used to solve the problem. A case study is provided to illustrate the application of the model.

Wentsao Pan, Wenbin Qian, Yating Xia, Zijuan Liu, Ying Liu

Commercial banks are both financial institutions and independent economic entities. Therefore, commercial banks need to pay attention to their own operating efficiency while serving the real economy. On the one hand, it is responsible to all shareholders to ensure their investment interests; On the other hand, it is necessary to safeguard the survival and development of the enterprise. Objective evaluation of commercial banks' economic benefits is of great practical significance in promoting China's commercial banks to improve their capital operation efficiency, improve corporate governance, enhance the level of financial system services to the real economy, and promote their own healthy development. Based on super-efficient DEA and DEA-Malmquist method, this paper establishes a new network DEA model. By measuring some indicators of 10 commercial banks in China from 2017 to 2020, it is found that the network DEA model can better measure the economic benefits of commercial banks in China than the single-stage DEA model. The study found that China's commercial banks have been groping for development in the process of reform, but have not yet reached the optimal scale of operation. The overall scale efficiency is low and the operating efficiency needs to be improved.

Weed Suppression and Plant Interaction in Foxtail Millet and Mung Bean Intercropping System

Binghua Li, Xiaomin Liu, Xian Xu, Bochui Zhao, Zhuolin Li

The intercropping of cereal crops and legumes might increase yield and improve farmland ecological environment, so it is adopted in many regions, especially in organic management fields. However, the knowledge on the interaction among foxtail millet (Setaria italica L.) and mung bean (Vigna radiata L.) intercropping and weeds is relatively limited. The field study was conducted in 2021 and included four planting patterns: (1) treatment F1M1, one row of foxtail millet and one row of mung bean; (2) treatment F2M1, two rows of foxtail millet and one row of mung bean; (3) foxtail millet monoculture and (4) mung bean monoculture. In order to clarify the interaction between weed and crop, their emergence, plant height, biomass and yield were investigated. The results showed that the two intercropping patterns both reduced weed emergence amount, significantly suppressed weed density and biomass compared with its monoculture. In intercropping treatment, the plant height, biomass per plant and yield of foxtail millet were higher than that of monoculture, and the biomass and yield of mung bean was lower than that of monoculture. The total yield of treatment F1M1 and F2M1 was 56.0% and 101.6% higher than that of monocultures. The land equivalent ratio of treatment F1M1 and F2M1 were 3.85 and 5.39, respectively. The aggressivity and competitive ratio of foxtail millet in the intercropping system was higher than that of mung bean and the indices of foxtail millet in treatment F2M1 was higher than F1M1. It meant foxtail millet was the dominant species in the intercropping system and foxtail millet in treatment F2M1 had more advantageous than F1M1. To sum up, the foxtail millet and mung bean intercropping patterns could enhance the weed suppression effects by the crops, and increasing the seedling density of the dominant crop foxtail millet could improve the integrative yield, but this could not substantially alter the weed suppression outcomes of the intercropping system. The data and results of this study are helpful to understand the competitive relationship among crops and weeds in foxtail millet and mung bean intercropping system.

Structural Monetary Policy and Heterogeneous Enterprise Leverage Ratio—Based on the Perspective of Soft Budget Constraints

Zhiwei Liu, Yi Qu

By constructing a dynamic stochastic general equilibrium model that includes soft budget constraints and financial accelerators, it explores the impact of "hardened" soft budget constraints on the economy and the differences in the response effects of different monetary policies. The study found that: First, weakening the soft budget constraint can alleviate the structural high leverage problem and reduce the distortion of the economy, but at the cost of a decline in total output. When the economy encounters a risk shock, the existence of soft budget constraints can calm economic fluctuations, but hinder the normal clearing of the market, causing a series of problems such as overcapacity and rising inventories. Second, the “one size fits all” tight monetary policy will not only fail to reduce the leverage ratio, but will also further increase the leverage ratio and exacerbate the degree of distortion of the economic structure. In contrast, structural monetary policies such as targeted adjustment of the reserve ratio are a better choice to deal with structurally high leverage in an economy. Third, monetary policy responds to the leverage ratio of non-financial enterprises (especially the leverage ratio of state-owned enterprises) to help reduce welfare losses.

Jie LI, Zhaopeng LIU, Zufeng ZHANG, Shilong FEI

Uncertainty theory is widely used in the financial field. As a path dependent option, Look back option is favored in the financial market because of its own characteristics and is often used by investors to avoid risks. Based on this, this paper proposes to use the Ornstein Uhlenbeck stock model to study the look back option price, and takes the uncertain mean reversion model as the assumption of interest rate treatment. In the traditional lognormal distribution, the one-way change of stock price with time. When using the Ornstein Uhlenbeck stock model, the stock price follows the index O-U process, this situation is avoided, and the characteristic of interest rate, the average value of interest rate fluctuation, and the interest rate follows the mean reversion model can be well reflected. Therefore, the actual situation of the financial market can be more appropriately reflected by the new stock model. Further, the pricing formula of look back option is further deduced and discussed. At the same time, it is explained through relevant special cases.

Limin Wang, Xuexin Wang, Shuoshuo Li, Quancai Deng, Yachao Si, Yongqiang Wu

An important step in controlling the leakage of reclaimed water supply systems is finding the main cause of reclaimed water leakage through data analysis in the water supply system. This can not only save water resources, but also provide a theoretical basis for the treatment of water leakage. Three parts of the work have been done in this paper. Firstly, the reclaimed water supply data at a university was collected and averaged by hours. Then, principal component analysis was used to reduce the dimension of the 24-hour reclaimed water supply data. Finally, the dimension-reduced datasets were clustered, which classified them into four categories. By analyzing the graphs of the four types of data, it was found that the period when water supply differences were relatively large was mainly concentrated at 0–5 o'clock in the evening. The main cause of water leakage was found after an investigation with logistics managers, which was the breakdown of the toilet in the student dormitory at night. This study revealed the main cause of reclaimed water leakage in a university. With the joint efforts of reclaimed water management personnel and logistics managers, the leakage of the reclaimed water pipe network has been greatly improved. This study has a certain reference significance for revealing the actual situation of water supply by data analysis, looking for reclaimed water reuse, and finding the cause of water leakage in urban water supply pipe network systems.

A New Paradigm of the Study of Women's History and the View of History of the May 4th Movement: Comment on Unswerving Ambition: The Virgin Phenomenon in the Ming and Qing Dynasties

Zhaoyang Sun

The book True to the Word: The Faithful Maiden Cult in Late Imperial China, written by Professor Lu Weijing, an American scholar, is a highly representative achievement in the study of women's issues. This achievement attempts to construct the discourse system of describing the life of virginity and the history of Ming and Qing dynasties, reveals many disputes and contradictions behind the phenomenon of virginity, and puts forward some questions and criticisms on the traditional historical view that ancient Chinese women are passive and negative. However, it is also worth criticizing and questioning the writing purpose of opposing and overthrowing the view of the May 4th Movement, and the excessive emphasis on self and ethnicism exposed in the research, and disregarding social justice and social progress. Although the May 4th historical view has its obvious drawbacks, it attaches great importance to the value of human life and the meaning of existence, and always exudes rational brilliance in its adherence to the basic idea of anti-oppression and liberation.

Study on the Current Situation and Countermeasures of Undertaking Industrial Transfer in Western China

Hongyu Zhi, Cao Bing

Industrial transfer has become a major trend of contemporary world economic development. China's industrial transfer is gradually developed from the eastern coastal agglomeration to the central and western regions. The cost of factors in the east keeps rising, while the western region is in the early stage of development, rich in natural resources, low cost of factors of production and large market potential, which will inevitably become an important bargaining chip for the western region to attract the industrial transfer of developed regions. Under such background, this paper analyzes the current situation of undertaking industrial transfer in western China from the aspects of scale, source of industry, level of industry, mode of industry transfer and construction of demonstration area of industry transfer. Through literature analysis and data analysis, it is found that in the process of undertaking industrial transfer in western China, the ecological environment has been destroyed, the state of "high growth, low development", the acceleration of disorderly competition, and the passive economic growth. Based on this, this paper also puts forward a series of corresponding countermeasures to these problems, in order to promote the western regions to undertake high-quality industrial transfer for reference.

Research on the Symbolic Mechanism of Constructing National Identity in Sports Event Ceremony Communication

Chunyang Li

Based on the classical theories of communication, semiotics and cultural anthropology, using the research methods of literature study, text analysis, induction and deduction, this paper makes a theoretical exploration on the symbolic mechanism of constructing national identity in sports events under the concept of ceremony communication. The research holds that ceremony communication can provide another paradigm for us to research sports event communication. Sports event ceremony communication includes two kinds of ceremonies and two communication fields, which provides an important identity space for modern countries. Among them, symbols always run through the sports event ceremony communication, and its mechanism of constructing national identity is as follows: the symbol system function of sports event ceremony communication is not only information transmission, but also symbolic construction of symbol meaning; In the sports events ceremony communication, once a single or combined symbol is connected with the country, it has the meaning of the country, and it becomes a national symbol that can represent the country through metonymy function; National symbols can arouse people’s collective memory and emotion towards the country, and make people anchor the reference of symbols as “identity, collective, nation and country”. At the same time, people can realize the spiritual image of “national community” by means of imagination, thus completing the construction of national identity.

Vocational education has the dual attributes of education and economy, which is inseparable from the transformation of economic structure and industrial adjustment and upgrading. However, the causal relationship, equilibrium relationship and variable coefficient between industrial economic development and different levels of vocational and technical education are not clear. To solve this problem, through Granger causality test and Johansen cointegration Test, this paper combs out the specific correlation between the education in higher vocational college, secondary vocational schools and technical schools and important industrial economies such as transportation, finance and real estate. It is found that the leveraging effect of vocational education on industrial economic development is significantly greater than that of industrial development on vocational education. This leveraging strength on industrial economic development is far more than the change of vocational education itself. At the same time, higher education personnels have more obvious support for knowledge intensive and technology intensive industries, while intermediate skilled personnels have stronger support for industries with large number of employees and rich levels of employment.

Effect of Structure on Oil-Water Separation Performance of Cylindrical Hydrocyclone

As a new type of oil-water cyclone separation, cylindrical cyclone oil-water separator has many factors affecting its performance. In this paper, the influence of inlet structure is studied by numerical simulation. The results show that the diversion effect of different port structures is different, which affects the flow field distribution in the hydrocyclone. Among them, the effect of rectangular spiral inlet diversion is the best. At the same flow area, the separation efficiency of spiral hydrocyclone is the highest, and the separation efficiency of circle is slightly higher than that of rectangle. The numerical simulation shows that the upper position of the inlet is conducive to oil-water separation

The Logical Path of Socialist Modern Family Building

Xiaoyan Liang

Family is the foothold of social progress and human modernization. In China, the traditional family view is the spiritual lineage of “family is the smallest country, and the country is made up of millions families”, which needs to deal with the dialectical relationship between the interests of small family and everyone based on self-cultivation. The classic Marxist family view is “where there is a country, there is a family", which starts with the social attribute of the family and points out that purifying the family relationship through social transformation makes the family become the basic unit of real emotional union. Therefore, the construction of the social state is the prerequisite for the construction of the family. In contemporary China, family building has entered a new stage. The logic of modern family building should be based on the Marxist theory of social relations, weakening the macro research path of the relationship between the state and the family, and strengthening the dimension of daily life of individuals. Starting from the criticism of daily life, it aims to transform people’s way of life, people’s family consciousness and the relationship between family members and social environment, to grasp the rules of family life from the perspective of the relationship between family and environment, and between man and nature. Finally, a family external environment that is closely related to social development is formed, and a healthy family internal environment is constructed to cultivate modern families and modern citizens, providing internal driving force for social construction.

Jie Wu, Yong Liu, Jing Xu, Cuizhu Wu

Myoglobin, a pigment protein mainly present in the sarcoplasm, serves as a decisive factor affecting the color of meat and meat products. In order to investigate the effect of heat treatment intensity on meat color during the brine treatment process of meat products, this paper takes pork as the research object, and studies the effects of different cooking time and cooking temperature on the water retention, color and myoglobin of pork. The results showed that, the water holding capacity of pork decreased gradually with the increase of heat treatment intensity; the lightness value (L*) of pork increased first and then decreased, while a* value decreased first and then increased, and b* value fluctuated little with the increase of heat treatment intensity. With the continuous increase of cooking temperature, L* value presented a fluctuating upward trend as a whole, a* value and b* value first increased and then decreased, reaching the maximum at 80°C. Myoglobin content and the ratio of its three forms were greatly affected by the heat treatment temperature. With the increase of heat treatment intensity, the myoglobin content continuously decreased, which changed drastically when the cooking temperature was below 80°C, but tended to stabilize after 80°C. The research results provide a theoretical reference for improving and controlling the pork processing quality in the brine treatment process and improving the quality of braised pork products.

Zhaoqiang Gao, Heng Zhang , Chao Ma

Hull deformation is an important factor affecting the consistency of ship attitude. Hull deformation measurement methods, such as optical measurement method, inertial matching measurement method, etc., can accurately measure the hull deformation. However, these measurement methods require the installation of deformation measurement equipment at the location where the deformation is measured, which limits the deformation measurement method to be used on large ships with numerous onboard equipment. In this paper, a ship deformation estimation technology based on neural network is proposed, analyzes the ship deformation transfer law, builds the ship deformation estimation neural network model, and estimates the deformation information of adjacent positions through the deformation information of the known position, so as to obtain the whole ship deformation information, and the attitude of the whole ship can be achieved. Finally, the experiment is carried out on a ship model, the relative deformation data of different positions and multiple directions are collected, the neural network model is trained, and the model is verified with the test data. The results prove the feasibility of estimating ship deformation transfer based on neural network.

Bin Ren

With the increasing transaction scale of the power market and the corresponding increase in transaction data, it is urgent to analyze power companies' collusive bidding behavior based on big data. Therefore, this paper combines an indexing system and unsupervised deep-autoencoder Gaussian mixture model to detect collusive bidding. First, this paper introduces an indexing system that includes structure, behavior, and influence indexes. Second, the Gaussian mixture model of the deep autoencoder is proposed according to the characteristics of high-dimensional index data. Then, using the compression network of the deep autoencoder, the hidden representation and reconstruction errors of the unit index data are obtained, and the loss function is constructed based on this data. The estimation network is then used to estimate the density, and the abnormal energy function of the unit is constructed to determine whether collusive bidding behavior occurs. Finally, a numerical example shows that compared with other traditional unsupervised study models, the deep-autoencoder Gaussian mixture model is more efficient and accurate in discriminating the bidding behavior of power producers.

Xiaoxi Kou, Yan Cao, Hu Qiao

With the rapid development of intelligent manufacturing, the data demand of assembly planning for product model tends to be diversified, standardized and accurate. Assembly model is the key to the expression of assembly semantics. The assembly hybrid G-diagram (AHGD), a model containing the semantics of assembly linkage and assembly priority relationship and capable of data transformation, is constructed based on the assembly structure of the product. From the perspective of part attributes, the functional parts are regarded as the main nodes of the assembly semantic model combined with the star topology to construct the assembly hybrid G-diagram based on functional parts (AHGD-F), which provides a visual model and data basis for subsequent intelligent planning under the premise of ensuring product functions. The assembly compatibility of AHGD-F model is analyzed by multicolor principle, so as to meet the requirements of assembly feasibility and ensure the functionality of assembly semantic model. The assembly semantic expression of AHGD-F model is verified by milling fixture, and the multi-color assembly compatibility analysis is carried out to provide effective assembly semantic verification for subsequent assembly sequences. The construction of visual assembly semantic model can clearly reflect the assembly relationship of product parts. The mapping and conversion of model and data provide reference and data information for later intelligent assembly, which can effectively reduce the error probability of assembly relationship data input.

Feng Ding

With the rise of deep neural networks, face recognition technology has developed rapidly. However, the low-quality video S2V face recognition under the conditions of poor lighting conditions and low resolution still does not achieve the expected effect due to the heterogeneous matching problem between the low-quality test video and the high-definition image of the sample library. Aiming at this problem, a low-quality video face recognition method based on super-resolution reconstruction is proposed. First, multi-dimensional features can be extracted by training video data with convolutional neural network; secondly, video features are input into the attention model, and local face features, face positions and temporal memory units are obtained according to the temporal continuity information of video data; finally, Q-learning is adopted. Iteratively calculates the output of the attention model, finds the optimal frame sequence containing the face, and uses this to calculate the video matching accuracy.The experimental results show that the method can effectively improve the accuracy of video face recognition in complex backgrounds.

As a living embodiment of the character, performer fluidly transforms himself from one character to another. The transformation is symbolized with costumes and properties. This performance is initially known in Siulak Kerinci in the 50s. In its original place, Minangkabau, the story developed from kaba or myth, created unconsciously to keep man and squirrel in harmony.Furthermore, this research aims to analyze elements which build Tupai Jenjang performance in Siulak Kerinci. Dramaturgy is used as an approach to analyze the structure and texture of the performance. As an aesthetic presentation, Tupai Jenjang reflects the modest reality of its audience life. Its modesty can be found everywhere, from setting decoration, properties and costumes to the lighting of the stage.

Akmal Rizki Gunawan Hsb, Acep Mulyadi, Albert Efendi Pohan — 2022-05-15

The Qur'an has given rise the discourse of thought and has experienced developments which Qur'an does not only have interpersonal relations with its society, but also has intercognitive relations. The discursive discourse of the Qur'an developed from the descriptive-narrative analysis pattern of Qur'anic study to the critical analysis. This article focused on discussing the thought development in the study of the Qur'an in academic studies conducted by the academic community. To achieve the goals of the study, writerapplied two analytical frameworks, namely the Qur'anic studies framework and the history of ideas. The first framework was used to map the genre of the work of the study of the Qur'an and the second framework was used to analyze the shift in thinking in the study of the Qur'an. This article shown the findings: (1) the development of thought in the study of the Qur'an has given birth to a thought model for the study of the Qur'an in the Traditionalist-Critical Frame. The traditionalist frame characterized by a theological-transmission dimension has two phases. First, the phase of the study of the Qur'an on the idraki-ta'rifi plain which consist of knowledge and introduction to the Qur'an. The second phase is the study which discussed the changing of the study of the Qur'an from idrak-ta'rif to a study which is tadris-naqdi or also called the rasah naqdiyyah li Qur'an (the critical studies to the Qur'an). The development of the study of the Qur'an has also given rise to models of thought in the Framework of Qur'anic studies, including; Al-Qira'ah Qur'an, part of the Qur'anic study framework that discusses reading and reciting the Qur'an. Tafhim Qur'an isthe part of the Qur'anic study framework which discussed the linguistic study of the Qur'an in the realm of interpretation which developed through semantic studies. Ta'riful Qur'an isthe part of the Qur'anic study framework which discussed scientific construction efforts to introduce new perspectives in studying the science of the Qur'an. Ta'limatul Qur'an is the part of the Qur'anic study framework which discusses the study of the Qur'an in the social-societal realm, a study which is emphasized in the analysis of the teaching of the Qur'an.

Zina Basim Muhammed, Tariq N. Musa — 2022-06-09

The aluminum cooking wares that were using in many countries, especially the developing countries be a source of free aluminum. Aluminum is recognized as a public health concern because of its potential toxic effects on human health. The present study was undertaken to determine the effectiveness of curcumin (CUR) in reducing the toxicity of leached aluminum through formation stable complexes. The available rhizomes in local markets contain 8.5% of curcumin as crude pigment. The maximum absorbance of curcumin at different pH values was determined. The curcumin-Al⁺³ complex was prepared by using tartaric acid as catalyst, at different pH values which in turn reflect the elimination percentages of Al⁺³ from the solution. The highly complexation was observed at pH 2.5, 3.0, 3.5 and 4.0. The Al⁺³ elimination at these pH values were 61.30,61.95,58.71 and 56.40% respectively. The stability of cur-Al⁺³ complexes at 25, 50, 75 and 100^oC for 60 min at pH 2.5 represent 96.94, 96.29, 95.55 and 95.52 % of the initial concentration respectively. The identification of curcumin and its complex with Al⁺³ by using Fourier-transform infrared spectroscopy (FT-IR) was achieved. The leached aluminum from three regions of aluminum cooking wares (local, Syrian and Iranian) were determined at different pH values, 1.5, 2.5, 3.5, 4.5, 5.5 and 6.5 at boiling point. In general, Iranian cooking ware leached more aluminum comparing with Syrian and local cooking wares. The elimination percentages of leached aluminum by using the most leaching cooking ware (Iranian) were 61.30 and 58.71% at 2.5 and 3.5 pH respectively, which is high comparing with other pH values.

Zihui Zhang, Minghao Li, Bao Shuang, Chenzhe Gao, Mizhou Hui — 2022-05-15

In order to study the main signaling pathways and the expression rules of key genes differentially expressed by different molecular weight hyaluronic acid on human colon cancer cells, Chinese hamster ovary cells (CHO) and pMH3 were used in this study to express the chimeric hyaluronidase PH20, and obtain stable expression and expression. Hyaluronic acid fragment HA35 was prepared by enzymatic digestion with high-purity PH20. Human peripheral blood leukocytes and human colon cancer cell line (HT-29) were used to establish inflammation-related colon cancer cell models, and they were randomly divided into control group and experimental group. The control group was cultured with complete medium for 24 h, in the experimental group, 20 μg/mL of high-molecular-weight hyaluronic acid (HA) and complete medium of HA35 were added for 24 h, and the effect of hyaluronic acid on the expression of TNF-α in inflammation-related colon cancer cells was detected by enzyme-linked immunosorbent assay (ELISA). Human colon cancer cells were collected and total RNA was extracted, reverse-transcribed to establish a cDNA library, and high-throughput sequencing was performed using an Illumina Hiseq X Ten sequencer to establish a transcriptome analysis platform at the mRNA level of HT-29 cells.Transcriptome analysis showed that there were 1372 differentially expressed genes in the HA treatment group compared with the control group, and 966 differentially expressed genes in the HA35 treatment group compared with the control group. These differential genes were mainly related to Rap1, Ras, PI3K-Akt, TGF-β and other inflammatory signaling pathways are related, and differential expression analysis found that HA may inhibit the further development of colon cancer cells by reducing the expression of inflammatory factors such as TNF, IL-17, and IL-22. This study can provide a reference for in-depth exploration of the molecular response mechanism of hyaluronic acid to inflammatory changes in colon cancer cells.

Luan Yunqi, Trifonova Tatiana, Goncharov Vladimir, Guo Peng — 2022-05-15

Severely cold climates have a significant impact on cardiovascular health. Studies have shown that green space, as an important health resource, can play a positive role in promoting cardiovascular health through the air environment and exercise. There are few studies on the correlation between urban green spaces and cardiovascular health in winter. In this study, Harbin was used as an empirical case and representative community samples were selected to explore the correlation between community green spaces and cardiovascular health. The results showed that the characteristics of green spaces in residential areas were related to cardiovascular disease and its risk factors. In communities with a green space ratio of less than 28%, residents are at higher risk of lack of exercise, overweight or obesity, high blood pressure and stroke. In communities with a green view index of less than 15%, residents have a higher risk of insufficient physical activity, overweight/obesity, high blood pressure, dyslipidemia, and stroke. There are also significant differences in the cardiovascular health scores of residents in communities with different green space characteristics. Emphasizing the importance of effectively increasing the ratio of community green spaces and the green landscape index to reduce the risk of cardiovascular disease may be of benefit to intervention efforts.

Review on Heavy Metal Contamination in Vegetables Due to Wastewater

2022-09-07

Because of the potential health effects of swallowing tainted food items, heavy metal contamination of soil and vegetative sections of plants as a result of wastewater irrigation is a severe issue. The impacts of trace elements (heavy metals) such as arsenic, cadmium, lead, chromium, nickel, and mercury, which are important environmental pollutants, are assessed in this article particularly in areas with high anthropogenic activities. In addition to these metals, copper, manganese, iron, and zinc are also important trace micronutrients. The presence of trace heavy metals in atmosphere, soil, and water can cause serious problems to living organisms, and the ever-present bioavailability of these heavy metal can result in bioaccumulation in the food chain which especially can be murderous to human health. This study reviews the heavy metal contamination in several areas of Pakistan over the past few years, especially to access heavy metal contamination in water (ground water, surface water, and waste water), soil, sediments, particulate matter, and vegetables. The contaminations affect the drinking water quality, ecological environment, and food chain. Furthermore, the toxicity caused by contaminated water, soil, and vegetables endangers human health. Increased population and high food demand result in the release of many contaminants into the environment, which eventually contaminate the food chain. Edible plants are the primary source of food for humans, and their contamination with toxic metals can have disastrous health consequences. Heavy metals affect the human health directly and/or indirectly; one of the indirect effects is the change in plant nutritional values. Previously, a

Number of review papers have been published on different aspects of heavy metal contamination. However, no related information is available about the effects of heavy metals on the nutritional status of food plants. This review study focuses on heavy metal sources, accumulation, transmission, health risks, and the impact of heavy metals on protein, amino acids, carbohydrates, lipids, and vitamins in plants. According to the research on heavy metals in food plants, both leafy and no leafy vegetables are good heavy metal accumulators. The bioaccumulation pattern in no leafy plants was leaf > root > stem > tuber. Because heavy metals have a considerable impact on nutritional values, plants produced on metal-contaminated soil were nutrient poor, and eating of such vegetables may lead to nutritional insufficiency in the population, particularly in poorer nations where malnutrition is already a problem.
