Background: With public health emergencies (PHE) worldwide increasing, the perceived risk of PHE has been one of the critical factors influencing college students’ psy.hological distress. However, the mechanisms by.which the perceived risk of PHE affects college students’ psy.hological distress are not clear. The study.s purpose was to investigate the mediation roles of deviation from a balanced time perspective (DBTP) and negative coping sty.es between the perceived risk of PHE and psy.hological distress. Methods: A convenience sampling method was used to survey.1054 Chinese college students with self-reporting. Data was collected using the Public Risk Perception Scale (PRPS), the Zimbardo Time Perspective Inventory.(ZTPI), the Simplified Coping Sty.e Questionnaire (SCSQ), the PHE Anxiety.Scale, and the Chinese version of the Patient Health Questionnaire (PHQ). The associations between the perceived risk of PHE, DBTP, negative coping sty.es, and psy.hological distress were clarified using the correlation analy.is. Additionally. the mediating roles of DBTP and negative coping sty.es between the perceived risk of PHE and psy.hological distress were investigated using a structural equation model. Results: The findings revealed low to moderate correlations between the variables studied. Students’ perceived risk of PHE was a positive predictor of their psy.hological distress (b = 0.219, p y.es play.d chain mediation roles between them with the effect being 0.009 and a 95% Boot CI of [0.003, 0.023]. This chain mediation model had an excellent fit index (χ2/df = 4.732, CFI = 0.973, TLI = 0.930, RMSEA = 0.048, SRMR = 0.047). Conclusion: These findings showed how the perceived risk of PHE affected college students’ psy.hological distress. Specifically. these results suggested that improving students’ mental ability.to switch effectively.among different time perspectives depending on task features and situational considerations and reducin

Light detection and ranging (LiDAR), as a hot imaging technology.in both industry.and academia, has undergone rapid innovation and evolution. The current mainstream direction is towards sy.tem miniaturization and integration. There are many.metrics that can be used to evaluate the performance of a LiDAR sy.tem, such as lateral resolution, ranging accuracy. stability. size, and price. Until recently. with the continuous enrichment of LiDAR application scenarios, the pursuit of imaging speed has attracted tremendous research interest. Particularly. for autonomous vehicles running on motorway. or industrial automation applications, the imaging speed of LiDAR sy.tems is a critical bottleneck. In this review, we will focus on discussing the upper speed limit of the LiDAR sy.tem. Based on the working mechanism, the limitation of optical parts on the maximum imaging speed is analy.ed. The beam scanner has the greatest impact on imaging speed. We provide the working principle of current popular beam scanners used in LiDAR sy.tems and summarize the main constraints on the scanning speed. Especially. we highlight the spectral scanning LiDAR as a new paradigm of ultrafast ***, to further improve the imaging speed, we then review the parallel detection methods, which include multiple-detector schemes and multiplexing technologies. Furthermore, we summarize the LiDAR sy.tems with the fastest point acquisition rate reported nowaday.. In the outlook, we address the current technical challenges for ultrafast LiDAR sy.tems from different aspects and give a brief analy.is of the feasibility.of different approaches.
