    Abstract Combining computer vision technology with process design, a new design and production method is obtained, which breaks through the limitations of traditional jewelry creation and provides new possibilities for the realization of complex jewelry structures. When technology no longer becomes the bottleneck of artistic expression, the space of art will be greatly expanded. Science and technology leading design method has become a new way to assist jewelry artists in subjective creation. According to various thoughts and ideas in design, establishing the corresponding algorithm rules and parameters can generate the scheme through calculation. The design result obtained in this way not only has a scientifically logical basis but also obtains the result beyond the normal imagination space due to the intelligent design process. This paper tries to apply computer vision technology to modern jewelry design, analyzes several aspects of computer vision application in process design, and combines the latest technical means to put forward algorithms for verification. The results prove that computer vision can improve the efficiency of crafts design significantly.

    Abstract Population projections rely on one-sex renewal models. Consequently, changing the projection of male mortality does not affect the projection of birth, contradicting commonsense. A two-sex renewal model is presented in this paper to provide a better description of reproduction and more reasonable population projections. This model is nonlinear and includes the one-sex renewal models as special cases. In this model, age-specific birth rates are defined for two sexes jointly; total fertility, net reproduction rate, and intrinsic growth rate are also derived for two sexes jointly; and age-specific populations approach or converge to stable status. Applying the two-sex renewal model to Australia, it indicates that one-sex models underestimated the intrinsic growth rate by 14 percent. Compared to the results of one-sex models, the two-sex model would provide higher growth rate for low-fertility countries, and lower growth rate for high-fertility countries. In other words, the one-sex models are commonly biased. If the two-sex model is applied to all the countries, it would project smaller populations for the world in the future.

    Abstract What is known and objective: Since WHO declared the pandemic of COVID-19, vaccines have been developed to fight against this infectious disease. Coordination and participation of investigational drug services to facilitate a phase III COVID-19 vaccination clinical trial are described and discussed, with novel interventions coordinating the dispensing processes in the trailer settings.
    Comment: Once the study has reached phase III, the large number of participants and fast enrolment would contribute to the vaccine development.
    What is new and conclusion: The investigational drug service (IDS) performed responsibilities in clinical and trailer units, and minimized workflow disturbances to maximize validity during the dispensing process. The advantages of mobile units and trailers increase flexibility of participants, broaden service area and improve feasibility, especially in minority and underserved communities. The UCM IDS team performs responsibilities in both clinical and mobile unit settings, the IDS team is able to facilitate and expand the enrolment to the minority population in underserved communities.

    Abstract Objectives: The rapid growth of health expenditure has always been the focus of health policy. This study aims to project health expenditure in Shanghai and to carry out policy simulations on the impact of chronic disease prevention programs on health costs in the Healthy Shanghai Initiative.
    Methods: Based on the Shanghai health accounts, component-based model was used to project Shanghai total health expenditure of 2020-2035, and the policy stimulation was implemented.
    Results: In 2020-2035, Shanghai's health expenditure is expected to grow continually, the proportion of total health expenditure in GDP will exceed 8.00% in 2023, reach 9.00% in 2025, and 10.03% in 2035. The proportion of current health expenditure in GDP will exceed 8.00% in 2024 and reach 9.55% in 2035. The chronic disease prevention plan help saving the medical expenditure of respiratory diseases,endocrine system diseases, and circulatory system diseases, accounting 3.28% to 10.58% of total health expenditure.
    Conclusions: The sustainability of health financing in Shanghai is facing challenges under the new normal of economy. It is necessary to promote the prevention and control of chronic diseases and strengthen cost control from both the supply and demand sides.

    Abstract Several penalization approaches have been developed to identify homogeneous subgroups based on a regression model with subject-specific intercepts in subgroup analysis. These methods often apply concave penalty functions to pairwise comparisons of the intercepts, such that the subjects with similar intercept values are assigned to the same group, which is very similar to the procedure of the penalization approaches for variable selection. Since the Bayesian methods are commonly used in variable selection, it is worth considering the corresponding approaches to subgroup analysis in the Bayesian framework. In this paper, a Bayesian hierarchical model with appropriate prior structures is developed for the pairwise differences of intercepts based on a regression model with subject-specific intercepts, which can automatically detect and identify homogeneous subgroups. A Gibbs sampling algorithm is also provided to select the hyperparameter and estimate the intercepts and coefficients of the covariates simultaneously, which is computationally efficient for pairwise comparisons compared to the time-consuming procedures for parameter estimation of the penalization methods (e.g., alternating direction method of multiplier) in the case of large sample sizes. The effectiveness and usefulness of the proposed Bayesian method are evaluated through simulation studies and analysis of a Cleveland Heart Disease Dataset.

    Abstract The U.S. public's trust in scientists reached a new high in 2019 despite the collision of science and politics witnessed by the country. This study examines the cross-decade shift in public trust in scientists by analyzing General Social Survey data (1978-2018) using interpretable machine learning algorithms. The results suggest a polarization of public trust as political ideology made an increasingly important contribution to predicting trust over time. Compared with previous decades, many conservatives started to lose trust in scientists completely between 2008 and 2018. Although the marginal importance of political ideology in contributing to trust was greater than that of party identification, it was secondary to that of education and race in 2018. We discuss the practical implications and lessons learned from using machine learning algorithms to examine public opinion trends.

    Abstract Oncolytic virus immunotherapy as a new tumor therapy has made remarkable achievements in clinical practice. And metabolic reprogramming mediated by oncolytic virus has a significant impact on the immune microenvironment. This review summarized the reprogramming of host cell glucose metabolism, lipid metabolism, oxidative phosphorylation, and glutamine metabolism by oncolytic virus and illustrated the effects of metabolic reprogramming on the immune microenvironment. It was found that oncolytic virus-induced reprogramming of glucose metabolism in tumor cells has both beneficial and detrimental effects on the immune microenvironment. In addition, oncolytic virus can promote fatty acid synthesis in tumor cells, inhibit oxidative phosphorylation, and promote glutamine catabolism, which facilitates the anti-tumor immune function of immune cells. Therefore, targeted metabolic reprogramming is a new direction to improve the efficacy of oncolytic virus immunotherapy.
