Response of Water Quality to Land Use and Landscape Pattern in the Ganjiang River Watershed.

Analysing the impact of landscape composition and structure on water quality at different scales is of great significance to water quality protection. The aim of this study was to determine scale-dependent impacts of land use/landscape patterns on water quality. The Ganjiang River, the largest water system in the Poyang Lake watershed, the largest freshwater lake in China. The response of water quality to land use and landscape patterns in the Ganjiang River watershed was explored based on land use and water quality data using redundancy and Spearman correlation analyses. Considering upstream monitoring of the entire Ganjiang River watershed; watersheds at the county level administrative region; and 1, 2, 5, 10, 15, 20, and 30 km-radius circular buffer zones, a total of nine scales of land use/landscape patterns that influence water quality in the Ganjiang River watershed were analysed. Results indicated that the county-level scale and the land use type of the 20 km-radius buffer zone upstream of the monitoring site were closely linked to water quality (96.28% and 93.23%, respectively). Among the land use types, construction land and cultivated land were the main output sources of pollutants. Regarding landscape pattern index, the greater the fragmentation of the landscape, the heavier was the water pollution load; the more the patches per unit area, the more stable was the ecosystem and the lower was the pollutant concentration. In addition, the eco-hydrological system of the Ganjiang River watershed was revealed to some extent through multi-angle analysis. These conclusions can serve as a reference for government departments to formulate land management and water quality protection measures.

Multi-angle analysis of Mo on martensite–austenite component and toughness in SCGHAZ of X80 pipeline automatic ring welding

In order to solve the embrittlement problem of welded joint of pipeline steel, this paper proposes to study the influence of Mo on M-A component of the subcritically reheated coarse-grained HAZ (SCGHAZ), and Mo on bainite transformation. Through the welding thermal simulation experiment, two kinds of X80 pipeline steel with different Mo content were set different secondary thermal cycle peak temperatures to simulate the heat affected zone (HAZ). Samples in the SCGHAZ were selected to observe the microstructure, M-A component, microalloy-element distribution and fracture crack trend, and comprehensively analyze the reasons for the deterioration of impact toughness caused by the changes of Mo content. The results show that the increase of Mo content leads to the formation of twinning martensite, which is one of the reasons for the deterioration of toughness. Mo is enriched at the interface of ferrite and M-A component, reducing the binding energy at the interface, resulting in the desorption of M-A component from the matrix, the formation of pores and becoming the nucleation site of cracks, resulting in the generation of micro-cracks and the decrease of toughness.

Measuring the Multiple Functions and Tradeoffs among Streets: A New Framework Using the Deep Learning Method

With the sustainable and coordinated development of cities, the formulation of urban street policies requires multiangle analysis. In regard to the existing street research, a large number of studies have focused on specific landscapes or accessibility of streets, and there is a lack of research on the multiple functions of streets. Recent advances in sensor technology and digitization have produced a wealth of data and methods. Thus, we may comprehensively understand streets in a less labor-intensive way, not just single street functions. This paper defines an index system of the multiple functions of urban streets and proposes a framework for multifunctional street measurement. Via the application of deep learning to Baidu Street View (BSV) imagery, we generate three functions, namely, landscape, traffic, and economic functions. The results indicate that street facilities and features are suitably identified. According to the multifunctional perspective, this paper further classifies urban streets into multifunctional categories and provides targeted policy recommendations for urban street planning. There exist correlations among the various street functions, and the correlation between the street landscape and economic functions is highly significant. This framework can be widely applied in other countries and cities to better understand street differences in various cities.

Research on the Commercial Value and Artistic Value of Video Games

Video games, as a relatively new but increasingly mature art form, gradually have a different value than other art forms as they develop. Video games can only be treated properly if the players are fully aware of their multifaceted nature. So the topic of this paper is the value of video games. This paper will try to solve the problem through multi-angle analysis and the experiential summary method. It can be concluded that the game's value is primarily comprised of its commodity and artistic value. As a commodity, games do make a lot of money for game companies. As art, games are indeed artistic and even have a higher dimension than other art forms.

Robot navigation based on multi-sensor fusion

Over the past years, with the rapid development of artificial intelligence technology, mobile robots have appeared in more and more fields. Different types of robots play different roles. Due to the complex indoor environment, there are still many technical problems to be solved for robots. Aiming at the shortcomings of single sensor, low mileage accuracy, and poor security in traditional mobile robot navigation systems, we propose a mobile robot autonomous navigation system based on multi-sensor perception. This system integrates mainstream synchronous positioning and mapping algorithms, path planning algorithms, and positioning algorithms, and uses multiple sensors to compensate each other to achieve the automatic navigation function of the mobile robot. In order to verify the reliability of the method, We have carried out multi angle analysis in the simulation environment, and the experimental results show that the proposed navigation system is reliable in operation, high in mileage accuracy, and good in robustness, which broadens the application scenario of mobile robots.

Enhancing Operating Efficiency in China’s High-End Equipment Manufacturing Industry: Insights from Listed Enterprises

The high-end equipment manufacturing industry is a strategic sector for China’s manufacturing transformation and upgrading. However, this industry is facing a series of challenges, such as insufficient innovation capabilities and poor business operations. This paper uses the super-efficiency SBM model to calculate the operating efficiency of listed companies in this industry from a micro perspective and conducts in-depth multi-angle analysis of their operating efficiency. Furthermore, Tobit regression is utilized to identify the factors that affect operating efficiency. The aim is to provide a pathway for companies in this industry to achieve efficiency maximization and sustainable development. The research shows that the average operating efficiency of high-end equipment manufacturing companies was around 0.7 from 2016 to 2021, and nearly 70% of companies were in a non-DEA efficient state. The operating efficiency of the intelligent manufacturing equipment industry is far higher than other industries, and the western region has great development potential. In addition to government subsidies, factors such as company age, equity concentration, regional GDP, and regional openness all have a positive impact on the operational efficiency of high-end equipment manufacturing companies. This paper combines the characteristics of the equipment manufacturing industry and analyzes their operating efficiency from multiple dimensions, providing decision support and pathways for the high-quality and efficient development of this industry.

A multi-angle analysis of injury induced by supplementation of soybean meal in Litopenaeus vannamei diets

Soybean meal is considered as one of the major components of Litopenaeus vannamei diets. However, most previous studies have focused on evaluating the effects of soybean meal on L. vannamei from the perspective of growth, physiology, and feed utilization; information regarding the analysis of serum metabolites, antioxidant and immune response, and intestinal microbiota is limited. Five diets were prepared, comprising 20% (T20), 28% (T28), 35% (T35), 42% (T42), and 50% (T50) soybean meal. A total of 600 shrimp were randomly distributed into 20 tanks (i.e., 30 shrimp per tank), with four tanks assigned to each dietary group. Shrimp were fed to apparent satiation during the 42-day feeding trial. The results showed that levels of serum globulin, alanine aminotransferase, and aspartate aminotransferase linearly increased (p < 0.01), but levels of high-density lipoprotein cholesterol linearly decreased (p < 0.001) as the proportion of soybean meal in the diet increased. Supplementation of shrimp diets with soybean meal linearly and quadratically increased (p < 0.05) serum total antioxidant capacity, levels of malondialdehyde, and activities of catalase, nitric oxide synthase and phenoloxidase. Hepatocytes in T35, T42, and T50 were shown to have different degrees of vacuolar degeneration, hepatic corpuscle atrophy, and star-like lumen loss. Dietary inclusion of soybean meal altered the composition of intestinal bacterial microbiota at phylum level, especially increasing the abundance of on other bacterial genera, whereas it had minimal impact on other bacterial genera and had no significant influence on the bacterial diversity. This study suggests that dietary supplementation of L. vannamei diets with soybean meal at concentrations exceeding 28% induces inflammation and oxidant damage of the hepatopancreas, and increases the risk of intestinal disease.

A cascade lithium bromide absorption refrigeration/dehumidification system for efficient energy recovery: Development, 3E optimization and life cycle assessment

In recent years, the problems of energy shortage and environmental pollution are becoming increasingly prominent, research on the optimization of energy systems and environmental pollution is imperative. Exergy, economic, and environmental (3E) analysis of a cascade LiBr-H2O absorption refrigeration/dehumidification system driven by low-grade waste heat is developed in this paper. Ecological Indicator 16 (EI16), total exergy destruction (EDtotal), and total annual cost (TAC) are considered as the objective functions of the 3E optimization model, and then, the optimal solution is obtained by TOPSIS and Shannon entropy method. Finally, life cycle assessment (LCA) of the cascade system is performed using EI16 and the environmental benefits of the cascade system are assessed in four stages, further enriching the evaluation criteria of this coupled system. The results shows that with the refrigeration temperature elevated from 2 °C to 10 °C, the EDtotal of cascade system increases from 336.90 kW to 339.14 kW, an increase of 0.66%, and the exergy efficiency decreased from 10.34% to 10.06%. At the same time, the cascade system TAC was reduced from 5.97 × 105$ to 5.77 × 105$, a 3.35% reduction. Economic analysis indicates that the investment cost increases with the increase of the refrigeration temperature, and the operating cost decreases with the increase of the refrigeration temperature. The optimal solution of the cascade system is obtained, and the EI16, EDtotal, TAC, and exergy efficiency are 2.6, 336.90 kW, 112.32 × 104 $ and 10.34%, respectively. The LCA illustrates that the construction process has serious impact on the environment, accounting for 95%, followed by the recovery phase. And improvements during the use phase determine the environmental benefits of the cascade system. In this work, multi-objective optimization and LCA are combined to provide a viable solution for the multi-angle analysis and evaluation of the cascade energy systems, and further refines the evaluation criteria for the cascade energy systems.

A Study of Choreography Courses for Musical Theater Majors

Musical theater education in Chinese universities is generally focused on training musical performance talents, and the dance courses involved are also set up to enhance dance performance. The dance styles learned are mainly ballet, modern dance, jazz dance and tap dance, which are common in European and American musicals. However, in the actual musical rehearsal process, the use of dance to create dramatic characters, develop dramatic events, and show dramatic emotions and conflicts requires the skilled creative ability of the musical choreographer. The educational process of musical choreography is a multi-faceted process, which requires the choreographer to have a solid theoretical basis and flexible creative skills. By comparing with universities in Europe, America and South Korea that have musical theater major, this paper studies the advantages and disadvantages of musical theater major courses in Chinese universities in terms of choreography training. Based on the actual situation of China, this study finds the curriculum that conforms to musical choreography through multi-angle analysis of practice, creation, and theory.

Precise Dissemination of E-Commerce Information and Behavior of Social Media Users

In order to solve the problem that the e-commerce system provides users with more and more choice information, it makes it difficult for users to find the desired products in a large amount of product information, and a research method for accurate dissemination of e-commerce information and behavior of social media users has been proposed. In order to improve the individual sales method of merchants, a method of multiangle analysis of data is proposed by clustering algorithm and classification algorithm. Research shows that there is a big difference between men and women in the use of WeChat, with women accounting for 70%. It can be seen that the respondents were mainly women. People aged 26-40 account for 62.4%, which matches the main consumer group (26-40 years old) in the industry research report. In terms of monthly disposable income, the median and mode are both between 1,000 and 2,000 yuan, which is related to the age distribution of the respondents. The frequency of online shopping 1-6 times/month accounted for 81.5% of the overall sample, and the online shopping experience for more than 1 year accounted for 98.8%, indicating that the respondents generally have the habit of online shopping. Through experimental analysis, the effectiveness of the improved algorithm is verified. In terms of online shopping consumption accounted for the total consumption, the number of people accounted for one-fifth and one-third. It can be seen that online shopping is an indispensable part of people’s daily consumption.

A theoretical study of atmospheric pollutant NO2 on as-doped monolayer WS2 based on DFT method

For the relevant properties of pristine and doped (Si, P, Se, Te, As) monolayer WS 2 before and after the adsorption of CO, CO 2 , N 2 , NO, NO 2 and O 2 , density functional theory (DFT) calculations are made. Calculation results reveal that the monolayer WS 2 doped with P and As atoms can be substrate materials for NO and NO 2 gas sensors. However, after the subsequent CDD and ELF calculations, it is found that P-doped monolayer WS 2 adsorbs NO and NO 2 in a chemical way, while As-doped monolayer WS 2 adsorbs NO and NO 2 in a physical way. Also, the charge transfer between As-doped monolayer WS 2 and NO is relatively small and not easily detected. Besides, As-doped monolayer WS 2 system exhibits greater differences in optical properties (the imaginary part of reflectivity and dielectric function) before and after the adsorption of NO 2 gas than before and after adsorption of NO gas. These differences in optical properties assist sensor devices in making gas adsorption-related judgments. Through the analysis of the recovery time, DOS and PDOS, As-doped monolayer WS 2 is also verified to be a promising NO 2 sensing material, whose recovery time is calculated to be as short as 0.169 ms at 300 K. • The interactions between five doped two-dimensional WS 2 substrates and six gases including NO 2 are analyzed and compared in detail. • The multi-angle analysis of various adsorption parameters and optical properties allows us to see that As-doped monolayer WS 2 has sufficiently strong selectivity and sensitivity towards NO 2 gas. • As-doped monolayer WS 2 adsorbs NO 2 in a physical way.

Evaluation of key microbial community succession and enzyme activities of nitrogen transformation in pig manure composting process through multi angle analysis

This experiment aimed to investigate changes in enzyme activity, microbial succession, and nitrogen conversion caused by different initial carbon-to-nitrogen ratios of 25:1, 35:1 and 20:1 (namely CK, T1 and T2) during pig manure composting. The results showed that the lower carbon-to-nitrogen ratio (T2) after composting retained 19.64 g/kg of TN which was more than 16.74 and 17.32 g/kg in treatments of CK and T1, respectively, but excessive conversion of ammonium nitrogen to ammonia gas resulted in nitrogen loss. Additional straw in T1 could play the role as a bulking agent. After composting, TN in T1 retained the most, and TN contents were 63.51 %, 67.34 % and 56.24 % in CK, T1 and T2, respectively. Network analysis indicated that many types of microorganisms functioned as a whole community at various stages of nitrogen cycle. This study suggests that microbial community structure modification might be a good strategy to reduce ammonium nitrogen loss.

Metabolic pathway-based molecular subtyping of colon cancer reveals clinical immunotherapy potential and prognosis.

Colon cancer presents challenges to clinical diagnosis and management due to its high heterogeneity. For more efficient and convenient diagnosis and treatment of colon cancer, we are committed to characterizing the molecular features of colon cancer by pioneering a classification system based on metabolic pathways. Based on the 113 metabolic pathways and genes collected in the previous stage, we scored and filtered the metabolic pathways of each sample in the training set by ssGSEA, and obtained 16 metabolic pathways related to colon cancer recurrence. In consistent clustering of training set samples with recurrence-related metabolic pathway scores, we identified two robust molecular subtypes of colon cancer (MC1 and MC2). Furthermore, we performed multi-angle analysis on the survival differences of subtypes, metabolic characteristics, clinical characteristics, functional enrichment, immune infiltration, differences with other subtypes, stemness indices, TIDE prediction, and drug sensitivity, and finally constructed colon cancer prognostic model. The results showed that the MC1 subtype had a poor prognosis based on higher immune activity and immune checkpoint gene expression. The MC2 subtype is associated with high metabolic activity and low expression of immune checkpoint genes and a better prognosis. The MC2 subtype was more responsive to PD-L1 immunotherapy than the MC1 subclass. However, we did not observe significant differences in tumor mutational burden between the two. Two molecular subtypes of colon cancer based on metabolic pathways have distinct immune signatures. Constructing prognostic models based on subtype differential genes provides valuable reference for personalized therapy targeting unique tumor metabolic signatures.

Multi-angle Analysis of Electric Vehicles Battery Recycling and Utilization

Under the dual pressure of resource and environment, electric vehicles (EVs) will gradually replace fuel vehicles as a new trend. Among them, the recycling and utilization of EV batteries have attracted much attention. This article indicates the classification of EV batteries and the importance of battery recycling, and proposes some measures to recycle batteries. The research in this paper shows that the current EV batteries mainly include lead-acid batteries, nickel-hydrogen batteries, lithium-ion batteries, lithium iron phosphate batteries, and ternary lithium batteries. It was emphasized that heavy metals leaked from waste batteries cannot be normally degraded by microorganisms in water bodies and soil, and heavy metals can endanger human health through the food chain through water bodies, plants, animals, etc. At the same time, the recycling of precious metals and valuable metals in the battery can realize resource recycling. Faced with the problems in the EV battery recycling and utilization industry, the customers should strengthen their awareness of battery recycling. The enterprises should work closely with other related enterprises to form a more complete battery recycling industry chain. The government should issue policies and regulations for supervision and management. And the recycling system for battery recycling, cascade utilization, and resource reuse should be improved. This article provides a way to maximize the utilization of EV battery resources, reduce the adverse impact on the environment, and achieve the goal of carbon neutrality as soon as possible.
