    Abstract The technological development in the new economic era has brought challenges to enterprises. Enterprises need to use massive and effective consumption information to provide customers with high-quality customized services. Big data technology has strong mining ability. The relevant theories of computer data mining technology are summarized to optimize the marketing strategy of enterprises. The application of data mining in precision marketing services is analyzed. Extreme Gradient Boosting (XGBoost) has shown strong advantages in machine learning algorithms. In order to help enterprises to analyze customer data quickly and accurately, the characteristics of XGBoost feedback are used to reverse the main factors that can affect customer activation cards, and effective analysis is carried out for these factors. The data obtained from the analysis points out the direction of effective marketing for potential customers to be activated. Finally, the performance of XGBoost is compared with the other three methods. The characteristics that affect the top 7 prediction results are tested for differences. The results show that: (1) the accuracy and recall rate of the proposed model are higher than other algorithms, and the performance is the best. (2) The significance p values of the features included in the test are all less than 0.001. The data shows that there is a very significant difference between the proposed features and the results of activation or not. The contributions of this paper are mainly reflected in two aspects. 1. Four precision marketing strategies based on big data mining are designed to provide scientific support for enterprise decision-making. 2. The improvement of the connection rate and stickiness between enterprises and customers has played a huge driving role in overall customer marketing.

    Abstract The multi-agent system is used to study the negotiation problem of virtual enterprises in the context of the Internet of Things (IoT) to strengthen the decision-making ability of enterprises and improve the negotiation efficiency between different enterprises. Firstly, virtual enterprises and high-tech virtual enterprises are introduced. Secondly, the virtual enterprise negotiation model is implemented using the agent technology in the IoT, including constructing the operation mode of the alliance enterprise agent and the member enterprise agent. Finally, a negotiation algorithm based on improved Bayesian theory is proposed. It is applied to virtual enterprise negotiation, and the effect of the negotiation algorithm is verified by setting an example. The results show that: (1) When one side of the enterprise adopts a risk-taking strategy, the number of negotiation rounds between the two sides increases. (2) High joint utility can be achieved when both parties to the negotiation adopt a conservative strategy. (3) The improved Bayesian algorithm can improve the negotiation efficiency of enterprises by reducing the number of negotiation rounds. This study aims to achieve efficient negotiation between the alliance and the member enterprises to improve the decision-making ability of the alliance owner enterprise.

    Abstract Background: The epidemic of acute coronary syndromes (ACS) poses a great challenge to depression. However, the prevalence of depression among ACS patients has not been fully determined. This meta-analysis aimed to provide an estimation of the global prevalence of depression among ACS patients (ACS depression).
    Methods: Online databases including PubMed, Cochrane Library, Web of Science, and Scopus were searched for all relevant studies that reported the prevalence of ACS depression through March 2023. Pooled prevalence of ACS depression with 95% confidence interval (CI) was estimated by the random-effect model. All statistical analyses were performed using comprehensive meta-analysis software. This review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) (identifier CRD42023409338).
    Results: A total of 28 studies (17 cohort studies, 9 cross-sectional studies, and 2 case-control studies) were included. The overall pooled prevalence of depression in ACS, derived from 28 studies, was 28.5% (95% CI: 0.28-0.29, P = .000, I2 = 99%). 21 included studies showed a prevalence of 20.3% (95% CI: 0.20-0.21, P = .000, I2 = 96%) in men, and the prevalence in women was 13.6% (95% CI: 0.13-0.14, P = .000, I2 = 95%). Subgroup analysis showed the lowest prevalence in Europe (20.7%, 95% CI: 0.20-0.22, P = .000, I2 = 98%); On different diagnostic criteria, the diagnostic and statistical manual of mental disorders (DSM-IV) (36.8%, 95% CI: 0.35-0.38, P = .000, I2 = 96%) has the highest prevalence. In terms of end year of data collection, the prevalence of ACS depression was lower for studies that ended data collection after 2012 (25.7%, 95% CI: 0.25-0.27, P = .000, I2 = 99%) than in studies before 2012 (30%, 95% CI: 0.29-0.31, P = .000, I2 = 98%).
    Conclusion subsections: This systematic review and meta-analysis suggest high global prevalence of depression among ACS patients, underlining the necessity of more preventive interventions among ACS patients especially in Asian and North American regions.

    Abstract Objectives: The study aimed to explore the depression profile of empty nesters and to identify heterogeneous subgroups in the elderly population. It explored the influencing factors of depression in elderly people with different depression profiles, with a view to provide a reference basis for improving the depression situation of empty-nesting elderly people.
    Methods: This study used the Chinese Longitudinal Healthy Lifespan Survey (CLHLS) survey data, with empty nesters over 60 as the research subjects. Latent profile analysis (LPA) was used to fit potential classes of depression in empty nesters; chi-square tests, Kruskal-Wallis, and multinomial logistic regression were used to explore the factors influencing different depression profiles in older adults.
    Results: A total of 4481 subjects were included in this study and were classified as low-level (11.6 %), moderate-level (51.6 %), and high-level (36.8 %). Compared to the low-level, the influencing factors for the high-level were IADL, anxiety, self-rated health, exercise, and education; and the influencing factors for the medium level group were anxiety, self-rated health, drink, and education. Factors influencing high-level relative to the mid-level group were IADL, anxiety, residence, self-rated health, exercise, and limited in activities.
    Limitations: The CESD-10, as a screening tool, could not completely determine the presence of depression in high levels of empty nesters.
    Conclusions: Psychological problems arising from depression among empty nesters seriously affected their overall health, and targeted intervention strategies should be developed for different categories of older adults to improve depression and enhance health-related quality of life.
