Published: July 2024

The prediction of the result of the competition is helpful for the coaches and athletes to adjust their strategy and state during the competition and to summarize and study the competition mode of the opponent after the game. For a long time, the prediction of tennis has focused on the prediction of winning and losing results, and the prediction results are often low, so our work is devoted to providing more reliable data analysis and match trend identification methods for this sport. Based on the data of The Champions Wimbledon 2023, Random forest algorithm was used to predict the mutation points obtained by Bayesian online change point detection algorithm. In this process, “momentum” was taken into account, three categories of features were constructed, and the resulting mutation points were screened. Finally, a high accuracy rate (higher than 0.8) was obtained, indicating that such mutation points contained useful information and had practical significance. Finally, we use an approximate expression of Taylor expansion and the method of undetermined coefficient to correct the weights for the features according to the extreme inversion in the schedule. This mutation point provides a new observation angle and idea for the coaches and athletes during a game of daily training, which is conducive to enlightening the athletes to achieve breakthroughs.

The Current Situation and Influencing Factors of Dietary Structure among Chinese College Students
Authors: Xu Yiran
Published: July 2024

Poor dietary structure has brought some negative impacts to Chinese college students. Although many literature has pointed out some defects and causes in the dietary structure of Chinese college students, there is still a lack of summary of these research results. The author searched multiple literature on the dietary structure problems of Chinese college students since 2021, classified them based on the causes of the mentioned dietary structure defects, and summarized several major reasons that lead to the current poor dietary structure of Chinese college students. At the same time, based on the relevant survey results of diet self-management (DSM) and some literature, the author attempts to provide suggestions that can improve the current situation. The reasons for the poor dietary structure of Chinese college students can be simply classified into four categories: excessive personal taste, poor dietary habits, lack of knowledge about healthy eating, and lack of a healthy eating environment. There is a phenomenon of mutual promotion and deterioration among these four types of reasons. A college student's DSM is a comprehensive result of multiple factors. Inducing positive factors that have a high impact on DSM can improve the DSM of college students and improve their dietary structure. In the future, the government and universities can mainly solve this problem from two aspects. On the one hand, it is to improve the personal nutritional literacy of students; On the other hand, it is to create a better dining environment.

Authors: Jiang Sijun
Published: July 2024

The purpose of this article is to talk about the fundamental functionalilties of the nervous system and its relation to the neuromorphic architecture. The neuromorphic architecture is built to imitate and perform the function of neuron and synapses in our brain. The change phases undergone by neurons and spike timing dependent plasticity performed by synapses are the main reason for the attraction gained in the field of accelerating artificial intelligence and remarkable power efficiency. A neuron is slightly negatively charged because the majority of the anions are interior to the cell membrane while the cations are exterior. Due to the permeability of the cell membrane, ions do not mix. Ions tend to move from region where its concentration is high to region where the concentration is low, causing the phenomena of resting membrane potential. Synapse is the one of the main components responsible for cognitive actions such as learning and forgetting, since it is essential for the transport and the processing of information. Memristors, the material, are used specifically since it has some distinct characteristics that differ from other component to perform the task of neurons and synapses. Different types of memristors are used for different aspects for the tasks, and this article is going to discuss a few of them.

Authors: Li Yukun
Published: July 2024

The Environmental, Social, and Governance (ESG) performance of companies has garnered widespread attention from all sectors of society in recent years. Studying its impact on the risk of stock price crashes is of great significance for maintaining the stable development of the securities market. This paper takes the listed companies on the Shanghai and Shenzhen A-share market from 2009 to 2022 as samples to explore the relationship between ESG performance, audit opinions, and the risk of stock price crashes. The study finds that: (1) Good ESG performance can significantly reduce a company's risk of stock price crashes; (2) Mechanism testing shows that companies with excellent ESG performance exhibit lower operational risks and significant misstatement risks, making them more likely to receive standard audit opinions. Companies that have received standard audit opinions will see a significant decrease in their future risk of stock price crashes; (3) Heterogeneity testing reveals that for companies in the manufacturing industry and small-scale listed companies, the negative effect of their ESG performance on the risk of stock price crashes is more pronounced. This research expands the understanding of the mechanism by which ESG performance affects the risk of stock price crashes, contributing to promoting sustainable corporate development and market stability.

Study the amplication effect of different slope subject to seismic loading
Authors: Gao Le , Huang Sizhe
Published: July 2024

The dynamic response and instability mechanisms of slopes under the influence of strong earthquakes have always been crucial areas of research in geological hazards. This study aims to delve into the stability of various types of slopes under seismic conditions. Utilizing the finite difference method, it unveils the dynamic response patterns of different slope types.And using the controlled variable method, this study meticulously analyzed the acceleration, displacement, and dynamic stress response of slopes with different angles, clarifying the impact of slope angle and varying accelerations on slope dynamic responses. The findings are as follows: The Peak Ground Acceleration (PGA) of slopes increases with elevation, reaching its maximum at the slope crest. This coefficient decreases as the slope angle increases, exhibiting a pronounced tendency for acceleration to be more pronounced near the surface. Displacement peaks, particularly sensitive to changes in seismic acceleration within the relative elevation range of 0.6 to 0.8, decrease with an increase in slope angle, especially beyond 60°, at which point the displacement response mechanism undergoes a change. Stress peaks diminish with rising elevation and become more pronounced with increased seismic load, indicating that the upper parts of slopes are more significantly affected by earthquakes. The increase in slope angle shifts stress concentration from the mid-slope towards the toe, particularly under steep slopes, where stress at the slope foot notably increases.
Analysis of the Alienation Theme in Eugene O’Neill’s the Hairy Ape: An Eco-Critical Perspective
Authors: Hou Yuchang
Published: July 2024

In the post-industrial era, with the high development of material civilization and the continuous progression of capitalism, the ecological crisis has become increasingly severe, leading to a significant imbalance in the social order. In this context, the lower-class laborers are often caught in an animal-like predicament of survival. In O’Neill’s play The Hairy Ape, the steamship symbolizes the capitalist society, and Yank’s tragic fate reveals the disorientation, confusion, loneliness, disillusionment, and disappointment towards social reality among modern Westerners. This play serves as a warning of the crisis of human alienation in the context of post-industrial civilization. Although Yank’s exploration fails, it remains a valuable attempt by humans to seek spiritual belonging in an alienated society. The pursuit of self-worth remains a permanent subject for human beings to contemplate. Therefore, this paper aims to analyze the theme of alienation reflected in The Hairy Ape from the perspective of Eco-criticism, mainly focusing on three aspects: natural ecology, social ecology, and spiritual ecology.

Published: July 2024

Taking a perspective of the upstream and downstream industry chains, this study investigates the factors influencing pork price fluctuations using monthly data from January 2010 to December 2023 in China as the research sample. A series of prices are selected from the upstream, midstream, and downstream segments of the pork industry chain. A panel VAR (Vector Autoregression) model is constructed, and robustness tests are conducted on the model. Specifically, employing methods such as impulse response analysis and variance decomposition of forecast errors, the empirical research examines the relationship between external shocks and price fluctuations at various stages of the pork industry chain. The research findings indicate: there exists long-term cointegration among live pig prices, piglet prices, wheat prices, corn prices, soybean prices, and pork prices; pork prices (downstream industry chain) exhibit both positive and negative feedback in the short term when impacted by prices in the midstream and upstream industry chains, displaying volatile fluctuations. As the time horizon extends, the magnitude of fluctuations decreases and tends towards zero; pork prices are primarily influenced by themselves, as well as live pig, piglet, wheat, and soybean prices.

Research On Underwater Search Strategy for Wrecked Submarine Based on Monte Carlo Simulation Algorithm
Authors: Lin Kangzhe , Guo Yunhao
Published: July 2024

In recent years, visiting undersea relics by submarine as a new type of tourism program has a high risk. In order to improve the safety of the submarine, an effective simulation is carried out for the submarine that loses power, and a reasonable method to optimize the search mode is proposed. In this paper, this paper consider a submarine that has lost power, which is subject to its own gravity by the buoyancy of the water and the resistance generated by the relative motion of the ocean current and the submarine, so this paper establishes and solves the differential equations of motion of the wrecked submarine in three-dimensional space according to Newton's second law. Also considering that the state of the submarine at the time of failure is unknown, Monte Carlo simulation is used to randomly sample 1000 sets of initial velocities and positions around a number of famous undersea sites and simulate their trajectories, so as to obtain the probability density distribution of the submarine's position at any given moment, and to plot the 3D and 2D images of the probability density distribution of the submarine's position at the end of each day. In the process of searching for submarines against multiple warships, this paper adopts a greedy search algorithm, which integrates the traveling speed of the searching ships, the search speed and the success rate of searching unit area. At the beginning of each day, the warships select the most probable submarine location based on Monte Carlo simulation and travel to that location for search. The search program has a high probability of finding the lost submarine within 10 days.

Authors: Huang Chenghao
Published: July 2024

This article investigated the efficacy and safety of antiretroviral medication (ART), namely protease inhibitors (PI) and non-nucleoside reverse transcriptase inhibitors (NNRTI), used by HIV/AIDS pregnant women. It emphasizes the relevance of ART management throughout pregnancy for maternal and child health, aiming to teach doctors and improve outcomes at the maternal and child levels. Objective. To study how HIV-infected pregnant women’s PI and NNRTI efficacy and clarity affect mother’s and baby’s health. Method. A systematic review was undertaken between 2002 and 2021 to assess the similarity groups of HIV-positive pregnant women and their fetuses. The analysis compared the effects of PI-containing and NNRTI-based ART. Over 45,000 pregnant women from 27 nations were analyzed in studies, with each receiving a distinct technique rating. Results. The systematic review included 10 studies in total, with 45,427 women participating. The findings revealed that there was no significant connection between PIs and NNRTIs for various fetal/neonatal outcomes. Therapeutic drug monitoring should be performed on PIs and NNRTI regimens with a small therapeutic window, respectively. The study of antiretroviral medicines with pregnant women indicated that both drug classes were safe throughout pregnancy, with PI-based regimens showing greater efficiency in achieving viral suppression. Hearing early ART initiation resulted in better neonatal outcomes. Conclusion. ART therapy for HIV-positive pregnant women must prevent toxicity and inadequate medication distribution. PIs reduce perinatal risk and inhibit viruses. Understanding patient-drug interactions is crucial because starting ARTs late is dangerous. Go-ahead tracking enhances mother and infant health, HIV-related pregnancy outcomes, and HIV management.

Published: July 2024

Hematological tumors are a significant disease that poses a serious threat to human health, with morbidity and mortality rates ranking among the highest for all types of tumors. Targeted and immunotherapy for hematological tumors have made significant progress in various aspects, and the utilization of new drugs has enhanced the overall effectiveness of treating hematological tumors. As medicine enters a new era of personalized treatment, monoclonal antibody drugs, with their unique mechanism of action and high efficiency, play an immeasurably important role in the treatment of malignant tumors. Monoclonal antibodies are also utilized as targeting agents for delivering nanomedicines containing cytotoxic payloads or directly linked to cytotoxic drugs. The use of monoclonal antibodies has become a popular treatment for hematologic tumors, as evidenced by significant commercial success. The main features of monoclonal antibody drugs compared to traditional chemical drugs are that monoclonal antibodies are biological drugs with higher biotransformation efficiency, i.e., a higher success rate, and fewer side effects. However, targeted drug monotherapy often yields poor remission rates, and the efficacy and safety of immunotherapy need further enhancement. This article will begin by discussing hematological oncology and provide an overview of the principles, advantages, and disadvantages of several common monoclonal antibody drugs currently available on the market. It will also explore the potential for combined use of monoclonal antibodies, offering direction and assistance for future research in this field.
