In July 2024, a shooting incident involving President Trump drew widespread public attention, highlighting the need for a deeper understanding of political rhetoric among U.S. Congressional members. This study analyzes discourse patterns on Twitter using large language models (LLMs), specifically ChatGPT and bidirectional encoder representations from transformers (BERT), to explore underlying factors that may contribute to polarizing political language. By collecting and preprocessing Twitter data, we initially labeled 20, 000 tweets using ChatGPT and then utilized the BERT-large model to classify the remaining 980, 000 tweets. The analysis identified party affiliation and geographic region as significant factors influencing political rhetoric. Republican lawmakers exhibited a higher prevalence of polarizing language, while New Jersey recorded the highest rate among the states. Newly elected Congressional members also tended to adopt more provocative language, potentially as a strategy to engage with their voter base or distinguish themselves in a competitive political environment. Temporal analysis revealed spikes in polarizing rhetoric corresponding to events such as discussions on the new fiscal year budget. This study offers insights into the dynamics of political discourse, providing a foundation for promoting constructive dialogue and fostering institutional resilience.

Drug-protein interaction (DPI) prediction in drug discovery and new drug design plays a key role, but the traditional in vitro experiments would incur significant temporal and financial costs, cannot smoothly advance drug-protein interaction research, so many computer prediction models have emerged, and the current commonly used is based on deep learning method. In this paper, a deep learning model Computer-based Drug-Protein Interaction CBSG_DPI is proposed to predict drug-protein interactions. This model uses the protein features extracted by the Computed Tomography CT and Bert method and the drug features extracted by the SMILES2Vec method and input into the graph convolutional neural network (GCN) to complete the prediction of drug-protein interactions. The obtained results show that the proposed model can not only predict drug-protein interactions more accurately but also train hundreds of times faster than the traditional deep learning model by abandoning the traditional grid search algorithm to find the best parameters.

Artificial intelligence has transformed marketing and consumer lives. However, despite its multiple beneficial effects, unprecedented artificial intelligence uses pose enormous challenges to consumer privacy protection. This research aims to provide a comprehensive picture of privacy research and enhance privacy protection. We first give more specific definitions of consumer privacy according to data analytic processes. Second, we investigate how AI-related factors, privacy risk, privacy protection, and other factors influence consumer privacy decision-making, and draw a conceptual model based on the extended Antecedents-Privacy Concerns-Outcomes (APCO) model. Third, we examine the potential risks of each data analytic step and the causes of privacy risks from consumer, company, and technology perspectives, and propose privacy protection schemes correspondingly. Lastly, we also provide agenda for future research.

Data pricing is a key link to promote the efficient circulation of data in the market. However, the existing methods are still insufficient in terms of pertinence, dynamism and comprehensiveness. Therefore, we proposed a data pricing prediction model based on sparrow search optimization XGBoost, aiming to provide a reference for pricing decisions in data market. First, we crawled the data transaction information of Youedata.com and performed preprocessing operations such as outlier processing, one hot encoding and logarithmic transformation on the dataset; Secondly, we conducted exploratory data analysis to understand the distribution of data and their correlation. Then, we used the LASSO algorithm to select features for the dataset and constructed a data pricing prediction model based on SSA-XGBoost. Finally, we compared and analyzed it with six machine learning models including LightGBM, GBDT, MLP, KNN, LR and XGBoost. The experimental results show that in terms of the R-squared, the prediction results of the proposed SSA-XGBoost model exceed the above six models by 4.9%, 7.4%, 7.1%, 23.8%, 12.8%, and 2.3% respectively, and are superior to the state-of-the-art work. Furthermore, the evaluation results of the five indicators of MSE, RMSE, MAE, MAPE, and RMSPE are better than other models, showing higher stability.

Given the rise of artificial intelligence, big data analytics has emerged as an important tool for processing and assimilating the enormous volume of data available on social media. It is of great theoretical and practical significance to explore the public opinion diffusion process and characteristics, and users' emotions of mega sports events based on big data statistics in the social media environment. This paper takes the Jakarta Asian Games, Russian World Cup and PyeongChang Winter Olympics held in 2018 as cases, uses text mining and social network analysis methods to analyze the dissemination process of social media users' data, presents the semantic words disseminated in sports events through high-frequency word cloud diagrams, and summarizes the general rules of public opinion dissemination. The results show that the more users' participation, the greater diffusion volume, and the diffusion process shows fast increasing, short duration, scattered topics, diversified contents, and strong guidance and weak continuity of attention. The high-frequency words, except for the names of the events, such as "cheer", "win the game" and "must win", have obvious concentration of emotional words.

As the era of large-scale highway maintenance arrives, the maintenance strategies have transitioned to a holistic approach that prioritizes safety, economic feasibility, and environmental sustainability. This research introduces a multi-objective optimization model for highway maintenance that incorporates the interplay of decision-maker preferences across three key objectives: Highway safety performance, maintenance engineering cost, and carbon emissions. This study employs a large-sample data analysis on a subset of the Lianhuo Highway network, which includes 2,842 pavement sections. This approach mitigates the impact of outliers, ensuring a substantial data buffer that fortifies the model's capacity for generalization and bolsters its robustness. The findings reveal a Pareto-optimal relationship among the three scrutinized variables. A particularly noteworthy observation is the M-shaped trajectory of carbon emissions, which initially rise, then decline, and ultimately rebound, contingent upon the selected maintenance strategy. Furthermore, an examination of the relationship between maintenance costs and safety performance discloses a trend of diminishing marginal returns, illustrating that the incremental gains in safety performance attenuate as maintenance investment escalates.

In the domain of data governance, crimes involving virtual currencies have emerged as an integral concern that cannot be overlooked. To address challenges such as the difficulty of evidence collection and the low probability of recovering stolen funds in virtual currency crimes, this paper proposes a new mechanism for the electronic storage and retrieval of evidence using blockchain technology, elaborating on its core steps and underlying technology. Moreover, from the perspective of virtual currency transaction intermediaries, this study employs game theory to analyze the issue, constructing replicator dynamics equations, solving for the Jacobian matrix, and exploring the direction of game evolution and the factors influencing the decision-making of the participants. This analysis demonstrates that the decision-making of virtual currency criminals is impacted by this electronic evidence mechanism, which can deter illicit intermediaries from assisting in money laundering activities, thereby reducing the feasibility of committing crimes with virtual currencies. Lastly, the paper offers policy recommendations to enhance the implement ability of the evidence storage and retrieval mechanism in regulating virtual currency crimes.

Since the COVID-19 pandemic began in late 2019, economic uncertainty and supply chain disruptions have significantly affected China's real economy. This has reduced consumer reliance on physical stores, increasing market and operational risks for brick-and-mortar retailers. This study analyzes the impact of the pandemic on shopping center performance using operational data from 7, 010 stores in China alongside COVID-19-related data. The analysis focuses on two indicators: Rent levels and lease termination rates, considering both rental and tenant perspectives. Findings reveal that COVID-19 negatively impacts retail rents and lease termination rates, with regions experiencing severe outbreaks facing greater declines. During lockdowns, the negative effects on rents and termination rates were more pronounced than during the broader pandemic period. Additionally, stores with sales-based rent experience a greater adverse impact compared to those without. The study concludes that the pandemic significantly reduces store rent while the likelihood of early lease terminations remains relatively low. These empirical results offer valuable insights for shopping center operational management and crisis response strategies.

With the rapid advancement of information technology, the sharing of educational resources has become an integral component of the modern educational system. However, traditional data elements in educational resources face challenges such as data security, copyright protection, and trust mechanisms. Blockchain technology, as a distributed ledger technology, offers innovative solutions for the sharing of educational resources data elements with its characteristics of immutability, decentralization, and transparency. This paper designs an educational resource sharing platform based on blockchain technology, and experiments have demonstrated that by optimizing the blockchain threshold elimination model, the overall performance of the platform can be enhanced, improving the security of data processing and achieving satisfactory results.

To address the issue of revenue distribution between government departments and enterprises in the operation of public data authorization, an evolutionary game model was constructed for both government and enterprise parties. The impacts of different incentive levels and revenue distribution ratios on the strategic choices and evolutionary trends of both government and enterprise were analyzed. It was found that when the government chose a strategy of weak authorization and strong regulation, enterprises showed a higher tendency to actively participate in public data sharing. In addition, when the revenue distribution ratio between government and enterprise was 3:7, the game evolution of both parties tended to be stable, reaching a balanced state that is beneficial and sustainable for both parties.

Connected and autonomous vehicles (CAVs) are expected to coexist alongside human-driven vehicles on roads for the foreseeable future. This study explores the stability and safety of mixed traffic streams, including traditional trucks and cars alongside CAVs. The study utilizes the intelligent driver model and cooperative adaptive cruise control model to characterize human-driven vehicles (including cars and trucks) and CAVs, respectively. It investigates how different ratios of trucks and penetration rates of CAVs impact the linear stability of mixed traffic flows and delineate their stability domains. Additionally, a simulation experiment is conducted using SUMO software to assess the safety implications of traffic congestion at on-ramp bottlenecks, specifically analyzing the safety dynamics of mixed traffic streams. The findings indicate that CAVs enhance both the stability and safety of mixed traffic flows. The presence of trucks is associated with reduced stability values at similar CAVs penetration rates. In scenarios without trucks, CAVs can elevate traffic safety by 58.28%-71.28%, whereas in the presence of trucks, although the enhancement diminishes, safety levels can still improve by 48.67%-65.11%.

This paper investigates the rank reversal issue in the selection of new energy vehicle types, focusing on consumers aged 20 to 30. It employs both the AHP and the PCbHA methods to rank four types of the new energy vehicles — pure electric vehicles, plug-in hybrid electric vehicles, range-extended electric vehicles, and fuel cell vehicles, based on ten influential factors: purchase cost, maintenance cost, fuel and electricity cost, safety, passability, endurance, appearance, brand power, power, and space. To verify the effectiveness of the PCbHA method in addressing the rank reversal problem, one alternative option is removed, and the ranking is recalculated with subsequent analysis of the results. The study finds that rank reversals often stem from the closeness of alternative weights. Through sensitivity analysis, this research reveals the impact of endurance attribute weight on decision outcomes, indicating that when the endurance weight reaches 0.35, the ranking of pure electric vehicles and range-extended electric vehicles reverses.

This paper proposes a new discrete-time Geo/G/1 queueing model under the control of bi-level randomized (p, N₁, N₂)-policy. That is, the server is closed down immediately when the system is empty. If N₁ (≥1) customers are accumulated in the queue, the server is activated for service with probability p (0≤ p≤1) or still left off with probability (1-p). When the number of customers in the system becomes N₂ (≥ N₁), the server begins serving the waiting customers until the system becomes empty again. For the model, firstly, we obtain the transient solution of the queue size distribution and the explicit recursive formulas of the stationary queue length distribution by employing the total probability decomposition technique. Then, the expressions of its probability generating function of the steady-state queue size and the expected steady-state queue size are presented. Additionally, numerical examples are conducted to discuss the effect of the system parameters on some performance indices. Furthermore, the steady-state distribution of queue length at epochs n^-, n and outside observer's observation epoch are explored, respectively. Finally, we establish a cost function to investigate the cost optimization problem under the constraint of the average waiting time. And the presented model provides a less expected cost as compared to the traditional N-policy.

The purpose of the study is to develop an approach to optimising the investment decision-making process using the dynamic programming method and its further integration into the enterprise information system using new technologies. The following methods were used in the study: System-structural analysis, dynamic programming method, graphical, and tabular methods. As a result of the conducted study, the role of information in the investment process was determined. An approach to the formation of the structure of an enterprise information system designed to optimise the investment decision-making process was proposed. The components of the structural elements of this system are considered — information collection, processing, and interpretation. A roadmap for information support for the development and implementation of an investment project is proposed, the blocks of which correspond to a certain direction of information processing, depending on the stage of implementation of the investment project — preparation, implementation, and final stage. The existing solutions are considered, and ready-made software products designed to optimise the investment process are characterised, primarily from the standpoint of risk assessment. An approach to optimising the investment decision-making process based on the dynamic programming method is proposed. An example of using this method to select one of the proposed alternatives according to the profit maximisation criterion is given. The results of the analysis can be used by the management board of enterprises to optimise the investment decision-making process.

Accurately forecasting gasoline volatility is significant for risk management, economic analysis, and option pricing formulas for future contracts. This study proposes a novel interval-valued hierarchical decomposition and ensemble (IHDE) approach to investigate gasoline price volatility. Our interval-based IHDE method can decompose the complex price process into different components to capture the distinct features of each component, which is helpful for forecasting and analyzing complex price processes. By using interval-valued data, the dynamics of gasoline prices in terms of levels and variations can be fully utilized in this study. Fully utilizing the informational gain of interval-valued data improves forecasting performance. In forecasting weekly gasoline volatility, we document that the proposed IHDE approach outperforms the GARCH, EGARCH, CARR, and ACI models, indicating the importance of capturing features of different frequency components and utilizing the informational gain of interval-valued data for gasoline volatility forecasts.

This study investigates the role of carbon emissions trading (CET) in advancing regional high-quality and green development (QGD) from quality and efficiency perspectives. Firstly, theoretical analysis via an evolutionary game model formulates hypotheses. Secondly, a multi-period DID model, based on panel data from 30 Chinese provinces (2007-2020), evaluates the impact of CET pilot policies on provincial QGD. Robustness and heterogeneity analyses assess variations by region, industrial structure, and economic development. Additionally, the moderating effects of government regulation and market conditions on the CET-QGD relationship are examined. Key findings include: 1) CET significantly improves both the quality and efficiency of QGD, with a stronger impact on efficiency. 2) Geographical heterogeneity reveals CET impacts peak in eastern provinces, moderate in central regions, and diminish in the west, amplified by industrialization and economic development. 3) Indirect governmental regulations, such as environmental spending and resource taxes, strengthen CET's effectiveness, whereas direct interventions like pollution control investments may hinder green transformation, adversely impacting QGD. 4) Increased carbon trading volumes improve QGD quality, while elevated prices enhance quality but reduce efficiency by favoring short-term emissions cuts over long-term green transitions. Therefore, this study recommends addressing regional disparities, balancing regulation with market mechanisms, and ensuring a competitive, transparent national CET market.

As an important path to promote the transmission of international knowledge and technology, the impact of two-way FDI coordinated development on one country's technological innovation efficiency deserves in-depth exploration. This study uses the fixed effect panel stochastic frontier analysis model and the coupled coordination model to measure the technological innovation efficiency and the two-way FDI coordinated development level of China's 31 provincial administrative regions from 2011 to 2021, and uses the fixed effect panel least squares regression model, the fixed effect panel quantile regression model, the Moran's index model, the fixed effect spatial Durbin panel model and the fixed effect panel β convergence model to test the impact of two-way FDI coordinated development on technological innovation efficiency. The results show that two-way FDI coordinated development can directly and significantly promote the improvement of technological innovation efficiency in the province, and with the improvement of technological innovation efficiency, the promoting effect of two-way FDI coordinated development has also become stronger. In addition, two-way FDI coordinated development can also indirectly generate significant positive spatial spillover effects on the technological innovation efficiency of neighboring provinces, narrow the technological innovation efficiency gap between regions, and thereby promote the efficient and balanced development of regional technological innovation activities. The research conclusions reveal the positive impact of two-way FDI coordinated development on the efficient and balanced development of regional technological innovation activities, which has enlightening significance for building a strong country in science and technology.

Developing rural revitalization industries is crucial for consolidating and expanding the achievements of poverty alleviation and establishing a solid material foundation for comprehensive rural revitalization. The "New Community Factory" in the Qinba Mountain area of Shaanxi Province, as a typical model for industrial revitalization, contributes to the high-quality development of rural areas. This article is based on the ocean model theory and conducts a comprehensive assessment and prevention of industrial risks in the "New Community Factory" model. The results indicate that the industrial risks faced by the "New Community Factory" throughout its development process fall into the category of "medium risk". Among them, the policy risk and environmental risk were highest during the period from 2014 to 2016, the economic risk was highest during the period from 2017 to 2019, and the scale risk and development risk were highest during the period from 2020 to 2022. To address prominent risks such as environmental risk and economic risk, it is urgent for the government to implement special financial policies, strengthen talent cultivation and guidance, support independent brand innovation, and improve the internal and external environment to promote the gathering and development of rural revitalization industries. This article not only enriches and expands the research scope of the ocean model but also has theoretical and practical significance for improving the risk assessment system of rural revitalization industries.

Quantum computation and artificial intelligence for military applications bring new capabilities, leading toquantum warfare. In this paper, we present a Holistic Warfare Model, introduced as a high-dimensional entangled warfare category including asymmetric conflicts. Its underlying metaphysics is entangled states fusion: This is the macroscopic entanglement concept inspired by high-dimensional quantum computation with the entangled wave-functions. From this entangled view, wars and battles are seen essentially as a holistic phenomenon: The distinct operation behaviors within different battlefields tend to the worldwide war. The mathematical Holistic Warfare framework developed in this paper expresses this fundamental view of arbitrary many interaction conflicts, each of them defined by its own battle-manifold and evolution simultaneously on the planet; we call this entangled category mathcal{WAR}. At last, we introduce the research directions in terms of the future wars, such multilateral conflict, cognitive warfare, biological warfare and unmanned operation so on.

In this paper, an evaluation index system for the coordinated development of regional economy was constructed by considering the aspects of regional development coordination, economic development coordination, economic and social coordination, and resource and environment coordination, which is used to perform comprehensive evaluation of the coordinated development of regional economy. On this basis, the impact of the upgrading of industrial structure, scientific and technological innovation, and government intervention on the coordinated development of regional economy were also investigated. According to the findings of our study, the coordinated development of regional economy in the eastern region was obviously better than that in the central region, while the western region had the lowest coordinated development of regional economy; the upgrading of regional industrial structure promoted the coordinated development of regional economy, while the promoting effect of the scientific and technological innovation on the coordinated development of regional economy were partly achieved by its promotion of the upgrading of industrial structure; the effect of government intervention couldn't be well reflected in the coordination index of regional economy.

This paper investigates the influence of various knowledge roles on knowledge diffusion empirically. Exponential random graph models (ERGM) are constructed, which provides a novel perspective for examining the factors that influence knowledge diffusion. Our empirical findings reveal that the endogenous structural effects of the network have a significant impact on the formation of diffusion relationships in citation networks and that there is a correlation between the number of the three knowledge roles - contributors, seekers and brokers - and the likelihood of citation relationship formation in citation networks.
