Abstract： The accelerator vacuum monitoring system is an important subsystem in the accelerator control system, which plays an important role in maintaining the normal operation of the accelerator. The design, development and development process of traditional large-scale control systems are highly dependent on physical entities, and the functional testing and performance verification of the whole system are all concentrated in the late stage of the project, resulting in a long development cycle of the control system, higher risks, and a tight time for late field debugging. To this end, industrial virtual debugging and virtual machine technologies were introduced to build a full-level virtual simulation debugging platform for the accelerator vacuum monitoring system. In the early stage of development, parallel collaborative development, full-level virtual debugging and logic rehearsal of the accelerator air monitoring system began to be carried out. Finally, the debugging results were applied to the site through on-site configuration, significantly shortening the time of on-site debugging. Reduce equipment loss and commissioning risk, improve project implementation efficiency and engineering design reliability.

Abstract： In light of the current international energy scarcity, nuclear power has emerged as a crucial source of clean energy. Proton accelerators have therefore become a pivotal technology in nuclear waste management. During beamline orbit correction processes, precise calculations of beamline orbit parameters are required. Given the demonstrated effectiveness of neural networks in a wide variety of industry domains, they offer promising potential for high-accuracy data fitting and prediction. Hence, this study proposes a novel direct linear accelerator beamline orbit parameter prediction technique based on edge intelligence computing nodes. This technique leverages BPNN to learn from historical data and generate a powerful model that can be seamlessly deployed to edge computing nodes, thereby accelerating the prediction of BPM location parameters. Furthermore, the proposed approach may be complemented by an adaptive compensation system in the future, which, in combination with edge computing nodes, could enable automatic beamline position correction, thereby achieving beamline orbit correction. Our experimental results demonstrate that FPGA, as an edge acceleration node, can achieve an inference speed of 2.5us, which represents a remarkable performance enhancement of approximately 165.6 times compared to CPU and approximately 7.9 times compared to GPU. The predicted results exhibit an average error of only 0.5%, and they exhibit the desired latency and accuracy characteristics.

Abstract： Human eating behavior is affected by many factors, including physiological, psychological, social, and cultural factors. Most attention from researchers regarding eating behaviors has focused on the effect that emotion has on eating behaviors. Eating behaviors generally manifest in the amount of intake and in the choice of food. By studying individuals’ clinical and non-clinical food intake while experiencing different emotions, researchers have concluded that negative emotions are more likely to cause individuals to overeat. However, the results of similar research on eating behaviors while individuals experience positive emotions vary. Physiologically, positive emotions can promote the individual's hedonic mechanism, which leads to increased eating behavior. Contrarily, self-control theory believes that positive emotions increase a person’s ability to resist temptation. The neurophysiological mechanism of eating behavior under the influence of emotions was further discussed in this study. In the future, in diet-related clinical research and treatment, it is necessary to have more in-depth exploration of the neural mechanisms of individuals’ eating behaviors when they are under the influence of various emotions.

Abstract： To achieve organizational goals, Internet companies often stimulate continuous innovation of employees by cultivating a happy and joyful work environment. However, the link between playful climate and employees’ innovative behaviors is still underdeveloped, primarily focusing on theoretical analyses and lacking empirical support. Building on the prior findings of playfulness in the field of organizational management, the present study explores three important issues. Based on the theory of organizational climate and the characteristics of playfulness, study 1 develops a scale to measure team playful climate in Chinese Internet firms. Standing on the team level study 2 discusses the cross-level mechanisms underlying the relationship between playful work environment and employees’ innovation from the perspective of Conservation of Resources Theory. Based on the Componential Theory of Individual Creativity, study 3 introduces individual thinking styles and multiple identities to explore the boundary conditions that stimulate employees’ innovative behaviors. Our findings have developed the concept of team playful climate in Chinese Internet companies, enhanced playful climate theory. And the implications for practice in the context of Internet companies are discussed.

Abstract： Today, drug abuse is closely being watched by most of society. It has been found that risky decision-making deficit is one of the main characteristics of drug abuse. Drug abusers are facing increasingly negative consequences in their personal, emotional, professional, and social lives. However, they still prefer to choose immediate reward, and it is difficult for them to make adaptive decisions. Several studies have shown that risky decision-making abilities of heroin addicts are impaired, but few studies have focused on the impact of different levels of monetary reward on risky decision-making for heroin addicts during abstinence and whether such effects are regulated by type of monetary reward. Therefore, this study used the balloon analogue risk task to examine the effects of different levels of hypothetical and real money rewards on risky decision-making in the abstinent heroin user. Two experiments were included in the study. In Experiment 1, a hypothetical reward was used. however, the participants were asked to imagine the money prizes obtained in the experiment as real money rewards and to obtain as much profit as possible. The results showed that the main effect of the reward magnitude was significant. Post-hoc testing showed the average adjusted pumps (the mean number of pumps for balloons that did not pop) and the total number of popped balloons were significantly less under the 1-cent reward condition compared with the 25-cent reward condition. The main effects of the group were significant, and post-hoc testing showed that the average adjusted pumps and the total number of popped balloons were significantly higher for the abstinent heroin users compared with the non-heroin users. The interaction between the reward magnitude and the group was not significant. Experiment 2 used real rewards. The final rewards of the participants were converted according to their performance in the experimental task. The results showed that the main effect of reward magnitude was marginal significant for the average adjusted pumps and the main effect of the reward magnitude was significant for the total number of popped balloons. Post-hoc testing showed the average adjusted pumps and the total number of popped balloons were significantly higher under the 1-cent reward condition compared with the 25-cent reward condition. The main effects of the group were significant, and post-hoc testing showed that the average adjusted pumps and the total number of popped balloons for the abstinent heroin users were significantly smaller compared with non-heroin users.The interaction between the reward magnitude and the group was not significant. The results of the study indicate that monetary reward magnitude has the same effect on risky decision-making of the abstinent heroin user as it does on the non-heroin user. The impact of money magnitude on risky decision-making is regulated by type of money reward.
