Abstract	Financial early warning mechanism is of great significance to the long-term healthy development and stable operation of listed enterprises. This paper adopts the logistic regression early warning model and BP neural network early warning model. Based on the BP neural network t early warning model optimized by the simulated annealing algorithm, the prediction effects of the model are compared from the perspectives of model accuracy and variable importance. Through the comparative analysis of the empirical results of the three methods, it can be seen that the simulated annealing algorithm has many advantages. The combination of the simulated annealing algorithm with multithreading, data compression, and segmentation greatly improves the efficiency of the algorithm and shortens the running time. Using the logistic regression early warning model and BP neural network early warning model and based on the BP neural network t early warning model optimized by the simulated annealing algorithm, the prediction effects of the model are compared from the perspective of model accuracy and variable importance. The results show that the three index dimensions of the BP neural network optimized by the simulated annealing algorithm have good discrimination ability to financial status. The BP neural network early warning model optimized based on the simulated annealing algorithm has good prediction accuracy and good practical significance.

Abstract	This study aimed to examine the impact of services development and technological innovation on the embedded location of the agricultural global value chain (GVC), and the interaction between the two in fifty-seven countries (regions) around the world. This study constructed an econometric model for empirical testing based on theoretical analysis. The results showed that services development and technological innovation contributed to the embedded location of the agricultural GVC, and there was a significant substitution effect between them. A sub-group test for different income levels showed that the influence of services development and technological innovation on the embedded location of the agricultural GVC was positive in high-income and upper-middle-income countries (regions), while their influence on the embedded location of the agricultural GVC was negative in lower-middle-income countries (regions). A significant substitution effect between services development and technological innovation is always present. Quantile regression results showed that the influence of services development on the embedded location of the agricultural GVC was significantly positive at all quantile points, but the significant influence of technological innovation and the interaction between the two on the embedded location of the agricultural GVC was mainly concentrated in the low and middle quantile points. From the perspective of services development and technological innovation, this study applied the analysis framework and research methods of the global value chain to the analysis of the global agricultural value chain, expanded the research scope of the global value chain, and provided a theoretical basis for countries (regions) to further deepen their agricultural global production network and agricultural GVC.

Abstract	Although the discrete element method (DEM) has been used to simulate soil-subsoiler interactions, the degree of soil heterogeneity along the depth profile has not been well documented. Models of a layered soil structure were developed using the DEM, and they were a heterogeneous soil model (HeS Model) with seven layers, a semi-heterogeneous soil model (SHeS Model) with three layers, and a homogeneous soil model (HoS Model) with one layer. The models simulated the soil dynamic behavior resulting from a subsoiler travelling at speeds from 2 to 6 km h−1. Simulations were compared with field measurements. Results showed that soil particles flow in front of the subsoiler formed three distinguished zones: “pushing”, “rising”, and “passive” zones, with the “pushing” zone having the highest particle velocities. Compared with the measurements, the overall relative errors of the simulated soil disturbance widths (W) within the range of working speed from 2 to 6 km h−1 were below 20 % for all three models. Whereas the overall relative errors of the simulated soil surface flatness (F) were larger than 20 % for all three models. These suggest that all three models are suitable for predicting W, but not for predicting F, if a 20 % relative error was used as the judging criterion. The overall relative errors of the simulated elevated soil area (A) were 11.1 %, 18.8 %, and 25.7 % for the HeS, SHeS, and HoS Models, respectively, which suggest that HeS Model had the highest accuracy in predicting A. This study provides critical information for determining the degree of soil heterogeneity in simulations of the dynamics of soil-subsoiler interaction.

Abstract	Background: This study investigates the link between SARS-CoV-2-associated long non-coding RNAs (lncRNAs) and lung adenocarcinoma (LUAD). LUAD is a prevalent and aggressive lung cancer type. The study aims to identify prognostic lncRNAs and construct a predictive model while shedding light on potential therapeutic targets during the COVID-19 era. Results: Eight SARS-CoV-2-associated lncRNAs with significant prognostic value in LUAD were identified, forming a robust prognostic risk model. The model exhibited strong predictive performance, with high area under the ROC curve (AUC) values at one, three, and five years. Furthermore, the risk score was an independent prognostic factor, correlating with the cancer stage. Notably, differences in immune function, drug sensitivity, and immune checkpoint expression were observed between high- and low-risk groups. Conclusions: This study unveils eight SARS-CoV-2-associated lncRNAs as valuable prognostic markers in LUAD, yielding a reliable prognostic risk model. Additionally, the model's ability to predict patient outcomes and its correlation with cancer stage underscores its clinical utility. The observed variances in immune function, drug sensitivity, and immune checkpoint expression suggest potential avenues for personalized LUAD treatment strategies. Clinicians can utilize the prognostic risk model to predict LUAD patient outcomes, informing treatment decisions. The insights into immune function, drug sensitivity, and immune checkpoints offer opportunities for tailored therapies, potentially enhancing patient outcomes. This study underscores the importance of considering the interplay between SARS-CoV-2-associated factors and cancer biology, especially in the context of the COVID-19 pandemic.How to cite: Zhou Q, Yuan T, Xie Z, et al.

Abstract	Bio-based materials have garnered considerable attention in the flame retardant field due to their inherent safety and environmental benefits. This study introduces a novel and eco-friendly flame retardant prepared through the Maillard reaction between glucose and poly(glutamic acid) for treating silk fabric. The study elucidates the synthesis of Maillard reaction products (MRPs) and verifies their deposition onto the silk fabric surface by observing changes in surface morphology, functional groups, and charged characteristics. The flammability tests demonstrate that MRPs treated silk fabrics had a high limiting oxygen index of over 27 % and a charred length of less than 12 cm, indicating effective flame retardancy. Moreover, the introduction of MRPs led to a significant decrease in smoke release when silk fabric underwent combustion. This observation can be attributed to the enhanced char formation and increased thermal degradation temperature of MRPs treated silk fabric. The electrostatic interaction between silk fiber and MRPs contributed to the fabric's resistance to repeated washing. Moreover, MRPs treated silk fabric retained their tensile properties and showed enhanced wrinkle-resistant performance. Generally, this research opens up a new path for the green preparation of halogen-free and phosphorus-free flame retardant protein fibers.

Abstract	Objective: To investigate the changes of immune response and side effects before and after nutritional intervention in cervical cancer patients with concurrent chemoradiotherapy. Methods: A total of 160 patients with primary cervical cancer who received concurrent chemoradiotherapy in this hospital between May 2016 and September 2017 were selected as the research subjects. Their nutritional intervention plans were reviewed and used to divide the patients into the control group (n=83) who accepted conventional nutritional support and the nutritional intervention group (n=77) who accepted targeted nutritional intervention. The differences in the contents of Th1/Th2 immunity indexes and humoral immunity indexes as well as the levels of bone marrow suppression-related indexes were compared between the two groups before and after intervention. Results: Before intervention, the differences in the contents of Th1/Th2 immunity indexes and humoral immunity indexes as well as the levels of bone marrow suppression-related indexes were not statistically significant between the two groups. After intervention, serum IL-2, IFN-γ, IL-4 and IL-6 contents of nutritional intervention group were lower than those of control group; serum IgA, IgM, IgG, C3 and C4 contents were higher than those of control group; peripheral blood WBC, RBC, Hb and PLT levels were higher than those of control group. Conclusion: Nutritional intervention can effectively optimize the immune status and reduce the bone marrow suppression reaction in cervical cancer patients with concurrent chemoradiotherapy.

Abstract	Agricultural fields are usually subjected to high amounts of traffic from field operations. The influence of traffic on sandy loam soil in three tillage systems were investigated in a field experiment. The field was located in a Canadian prairie region. In the experiment, the treatments were three tillage systems: no-tillage, disc tillage, and spring-tine tillage. Following tillage operations, field plots were trafficked with one pass of a sub-compact tractor. Soil properties were measured before and after the traffic to examine the effects of tillage systems and wheel traffic. For the effects of the tillage systems on the soil bulk density, soil shear strength, soil surface resistance, and soil cone index, the no-tillage system had higher values for all the soil properties when compared with the disc and spring-tine tillage systems. The plant (canola) population density ranged from 18.2 plants/m 2 to 34.9 plants/m 2 , with the no-tillage having the lowest plant densities. For the effects of wheel traffic, one pass of the tractor in the disc and spring-tine tillage plots resulted in a 2.7% and 17.4% reduction in soil moisture content, respectively. After wheel traffic, the average soil shear strength for the disc and spring-tine systems were still significantly lower than the no-tilled system. Sinkages of 40 and 50 mm were observed for the spring-tine and disc tillage systems, respectively. The results of this study highlight the importance of preventing the demerits of soil compaction induced by wheel traffic after tillage operations.

Abstract	Informatization teaching mode emerged under the tide of informatization development. The way of information dissemination and the process of human cognition have undergone tremendous changes in the era of informatization. Based on the vision sensor digital image and the fusion association rule mining algorithm, this paper studies the informatization teaching mode, aiming to analyze the influence of the vision sensor digital image and the fusion association rule mining algorithm on the foreign language teaching and enhance development decisions. The structure of digital image is analyzed by using image acquisition and processing technology and data transmission, and the digital image correlation method is explored. The use of data mining algorithms to conduct statistics on data integration related teaching documents in the past five years provides a strong basis for the data of the research process. In addition, in order to conduct a more detailed and comprehensive research on the informatization teaching model, the research scope was narrowed and the survey method was adopted to understand and collect data from relevant personnel and finally put forward constructive opinions for the purpose of the existing problems. The findings of the study demonstrated that the application of digital images can greatly expand the teaching content and greatly improve the creativity, experience, inclusiveness, and interactivity of teaching applications. The most obvious one is the sense of experience. The measured index has increased by 5.4 points.
