Summary: This paper studies a dynamic vaccination game model embedded with vaccine cost-effectiveness and dyadic game during an epidemic, assuming the appearance of cooperation among individuals from an evolutionary perspective. The study finds that vaccine factors, such as efficiency, cost, and benefit, are crucial in changing human vaccine decisions and cooperative behavior.

Summary: In this study, a novel donation game model was proposed to investigate the impact of reputation on the evolution of tag-mediated altruistic behaviors. The results indicate that the combination of reputation and tag greatly promotes the evolution of altruistic behaviors within a structured population, and the reputation threshold has a decisive effect on the dominant strategy within the population.

Summary: This study explores the relationship between claustrophobic tendencies and spatial needs in digital interfaces. Results show that individuals with stronger claustrophobic tendencies are more likely to have a stronger need for digital space, especially in designs with a complex grid layout. Interestingly, claustrophobic tendencies are more closely associated with spatial needs for cognitive tasks, rather than device-related preferences.

Summary: This study proposes a novel utility model of the vaccination game, considering the influence of strategy conformity on individual decision-making. The findings reveal that moderate strategy conformity and a high herd immunity threshold have a significant positive effect on promoting vaccination behavior when the initial vaccination fraction is low. For a high initial vaccination fraction, strong strategy conformity and high herd immunity threshold are more conducive to encouraging vaccination behavior.

Summary: This study investigates the relationship between the number of COVID-19 vaccination injections and fear of COVID-19 among Vietnamese adults. The results suggest that young adults aged 18-20 are more fearful of COVID-19 compared to other age groups. Individuals who received their first vaccine dose exhibit greater fear of COVID-19 compared to those who received the second dose or were not inoculated. Additionally, beliefs about the benefits of COVID-19 vaccination play a role in the relationship between the number of vaccination injections and fear of COVID-19.

Summary: This study proposes a model of vaccination on a hypergraph to explore the influence of individual and group factors on vaccination behavior. The experimental results show that vaccine cost determines vaccination in low adoption strength, while group-payoff is prioritized to promote vaccination in high adoption strength.

Summary: Explaining the coexistence of individual choice and government policy in real society is a challenging scientific problem. By combining evolutionary game theory and optimal control theory, the optimal allocation of resources for vaccination and self-defense measures can be determined, maximizing control of infectious diseases while minimizing costs.

Summary: Informers play a significant role in cooperation behavior by labeling defectors and promoting cooperation. With an increasing proportion of informers, cooperation can be further enhanced, and there is an obvious threshold in the change of informers' proportion.

Summary: This paper proposes a new spatial public goods game model that takes into account the influence of current and historical reputation on strategy learning. Simulation results show that individuals are sensitive to their own reputation, the reputation of their neighbors, and changes in neighbors' historical reputations, which all contribute to cooperative behavior in the system. However, paying attention to more historical reputation changes in neighbors does not further promote cooperative behavior.

Summary: Trust in institutions and democracy plays a significant role in COVID-19 vaccine acceptance. The study found that factors such as trust in institutions, trust in non-pharmaceutical interventions, and various demographic factors were associated with intent to vaccinate. History of influenza vaccination and satisfaction with democratic institutions were highly predictive of COVID-19 vaccine acceptance. Results also showed that social determinants of health and receiving the flu vaccine were predictors of COVID-19 vaccine acceptance.

Summary: This study examines the impact of punishment methods on the evolution of cooperation in a group. By introducing conditional punishment and considering individual reputation, the choice between traditional punishment and exclusion is determined. The results show that higher reputation thresholds are more favorable for the evolution of cooperation. Even a very small enhancement factor can encourage cooperation when the reputation is relatively high.

Summary: Research has shown that the presence of non-competitive individuals contributes to promoting cooperation in the system, while emotional cumulative length plays a key role in overall cooperation, with the cooperation rate of competitive individuals peaking at an intermediate value of emotional cumulative length.

Summary: Due to the conflict between limited resources and infinite demand, the impact of limited resources on human behavior cannot be ignored. In this study, a resource-based conditional interaction model is proposed to investigate the evolution of cooperation. The model is validated using the prisoner's dilemma game and asynchronous strategy update. The results demonstrate that promoting cooperation can be achieved through an optimal tolerance interval.

Summary: A new SEIRS-based ODE model is developed, considering asymptomatic and symptomatic infections, hospitalized and immune states, as well as a time-variable vaccination rate defined by a behavior model. Social Efficiency Deficit (SED) is employed to quantify the occurrence of social dilemma behind the model dynamics. Numerical results suggest that the presence of social dilemma depends on the fraction of asymptomatic infected individuals, the discount ratio of infected force, vaccination cost, and immunity waning rate. The behavior model may cause a slight social dilemma even in disease-free region (R0 < 1), while a relatively strong social dilemma is indicated when the behavior model results in fewer vaccinated individuals than the social optimal state requires for disease remission.

Summary: This paper proposes an approximate optimal strategy based on a piecewise parameterization and optimization (PPAO) method for solving optimization problems in stochastic control systems. The method obtains a piecewise parameter control by solving first-order differential equations, which simplifies the control form and ensures a small model error.

Summary: This investigation studies the impact behavior of a contact body in a fluidic environment. A dissipated coefficient is introduced to describe the energy dissipation caused by hydrodynamic forces. A new fluid damping factor is derived to depict the coupling between liquid and solid, as well as the coupling between solid and solid. A new coefficient of restitution (CoR) is proposed to determine the actual physical impact. A new contact force model with a fluid damping factor tailored for immersed collision events is proposed.
