Abstract	Dynamic visual experience is the most common way for people to perceive a cityscape. Previous research reviews on cityscapes have mainly focused on spatial planning, social culture, economic development, ecological protection, etc., with little consideration of the impact of dynamic visual perception on the formation of cityscapes, which hinders the provision of references for the practice of people-centered urban design concepts. Therefore, this article selected 94 works in the relevant literature from 1940 to 2022 to conduct a critical review. First, we conceptualized the cityscape in light of earlier substantial discussions on the intimate relationship between dynamic visual perception and the cityscape. Then, we divided the relevant research from the past century and a half into three periods and summarized theoretical and practical research on the cityscape in these different periods from the perspective of dynamic visual perception. Among these, the refined research on interdisciplinary methods, including Visual Quality Assessment based on dynamic visual perception and visibility analysis algorithms based on digital technology, is emphatically described and discussed. Based on a comprehensive review, this article concludes that the main application scenarios for the existing research on dynamic visual perception are cityscape assessment and decision making. Finally, three avenues for future research are proposed.

Abstract	To generate a new ornamental image, add an image’s oil painting style information to any image while preserving the image’s semantic content. With the rapid advancement of deep learning (DL), image style transfer has become one of the most active areas of computer vision research (CV). This paper proposes an oil painting style transfer technique based on parallel convolutional neural networks to address the ineffective style transfer of locally similar regions in content images and the slow processing speed of existing methods. By incorporating Gaussian sampling and a parallelization algorithm, this method effectively transfers the style of an oil painting. The algorithm can combine the content of any image with a variety of well-known oil painting styles to create high-quality works of art. The experimental results indicate that, compared to existing methods, the proposed method can effectively reduce the style loss of the generated image, make the generated image’s overall style more uniform, and produce a more pleasing visual effect.

Abstract	With the vigorous development of new media, aesthetic education plays a pivotal role as a vital and necessary link for the development of quality-oriented education in colleges and universities. However, colleges and universities nowadays value knowledge education more than aesthetic education, aesthetic education curriculum remains to be diversified and enriched, and aesthetic education practice activities tend to be in a superficial form, all of which have turned aesthetic education into an obstacle affecting the overall development of college students. We should practically grasp the development status and problems of college aesthetic education, and systematically analyze the reasons of such problems, which is of great practical significance for the establishment and development of contemporary aesthetic education curriculum system.

Abstract	With the deepening of the concept of sustainable development, the academic community has paid more and more attention to how enterprises can achieve value co-creation for multiple stakeholders from the perspective of corporate innovation. ESG is a new concept concerned with how to achieve sustainable development in enterprises in terms of environment, society, and corporate governance. However, there is still a lack of research on how to reshape the innovation processes of enterprises based on the new concept of sustainability and bring competitive value to corporate value. Based on this, we took the listed companies on the main board of the Shanghai and Shenzhen A-shares from 2010 to 2020 as the research object and empirically tested the impact effect of corporate ESG on corporate value, as well as the mediating effect of corporate innovation between corporate ESG and corporate value. At the same time, the institutional environment was incorporated as a moderating variable to further explore its influence mechanism. Finally, the heterogeneity of corporate ESG on corporate value was analyzed at both an enterprise level and a regional level. The results show that corporate ESG and its three sub-dimensions can significantly improve corporate value and innovation level; the internal mechanism shows that corporate innovation plays a mediating role between corporate ESG and its three sub-dimensions, while institutional environment play a moderating effect; non-state-owned enterprises’ ESG has a higher impact on corporate value than state-owned enterprises, especially in eastern China, where the value enhancement effect of ESG is more significant.

Abstract	Abstract Nowadays, exoskeleton is broadly used in the rehabilitation training of many postoperative patients. However, the uncertainty and disturbances caused by different patients and system itself may lead to incompletely rehabilitation training as planned, or even unsafety. This paper addresses the control problem of a lower limb exoskeleton, in the spirit of the recent progress on model predictive control (MPC) and extended state observer (ESO). More precisely, our approach is based on the strategy that designing an ESO to estimate the total disturbance of the dynamics model and compensating it in the design of the MPC process. To accomplish this, we introduce the virtual control quantity to decouple the dynamics model of the system and summarize the human disturbances, unmeasured states and system non-linearity as the total disturbance of the model. By doing so, the uncertainty can be estimated by our designed ESO. Based on the moving horizontal optimization and feedback mechanism of MPC, the output prediction of the system can be more accurate since the uncertainty are effectively compensated. The virtual experiment results demonstrate that proposed controller significantly improves the control accuracy on lower limb rehabilitation exoskeleton with disturbances (improved by over 34 $$\%$$ % ), comparing with conventional MPC and fuzzy PID. As a result, our achievements will make contributions to better rehabilitation training for patients using rehabilitation exoskeletons.

Abstract	The basal ganglia are known to be essential for action selection. However, the functional role of basal ganglia direct and indirect pathways in action selection remains unresolved. Here, by employing cell-type-specific neuronal recording and manipulation in mice trained in a choice task, we demonstrate that multiple dynamic interactions from the direct and indirect pathways control the action selection. While the direct pathway regulates the behavioral choice in a linear manner, the indirect pathway exerts a nonlinear inverted-U-shaped control over action selection, depending on the inputs and the network state. We propose a new center (direct)-surround (indirect)-context (indirect) ‘Triple-control’ functional model of basal ganglia, which can replicate the physiological and behavioral experimental observations that cannot be simply explained by either the traditional ‘Go/No-go’ or more recent ‘Co-activation’ model. These findings have important implications on understanding the basal ganglia circuitry and action selection in health and disease.

Abstract	Abstract Coal mining machine drums are prone to damage and malfunction under extremely complex working conditions, which seriously affects the efficiency and safety of coal production. In this paper, based on the theory of coal rock cutting and virtual simulation technology, finite element models of drum cutting coal rock were established and then verified by physical experiments. Through simulation analysis, the dynamic reliability of the drum was studied from three aspects: load, stress and wear, and a mathematical model of drum load was established with respect to the traction speed and drum rotation speed; based on the orthogonal test, the optimal working parameters to improve the wear resistance of the drum were derived. The results of the study found that when the traction speed increases, the load on the drum increases, and when the drum rotation speed increases, the load on the drum decreases; when the traction speed is increased from 2 to 6 m/min, the stress on the pick body under different rotation speeds increases to different degrees, with an average increase rate of 27.394%; when the drum rotation speed is 90 r/min, the traction speed is 3 m/min, and the coal loading mode is projectile loading, the wear depth of the picks and spiral blades is relatively small. The research method and results of this paper can provide a reference for the selection of the drum working parameters.

Abstract	A considerable amount of evidence suggests that parental marital conflict is an important factor in adolescents' internet gaming disorder (IGD). However, the mechanism underlying this relationship remains unclear. Therefore, the purpose of this study is to explore the relationship between parental marital conflict and IGD among Chinese adolescents, and whether this relationship is mediated by deviant peer affiliation and teacher-student relationship. There were 698 Chinese adolescents that took part in the study (51.58% male; Mage = 13.52). They completed self-report questionnaires regarding perception of parental marital conflict, deviant peer affiliation, teacher-student relationship and IGD. Structural equation model (SEM) was used to examine the relationship between parental marital conflict and adolescents' IGD, as well as the mediating roles of deviant peer affiliation and teacher-student relationship. Correlation analysis showed a positive correlation between parental marital conflict, deviant peer affiliation, and IGD, as well as a negative correlation between them and teacher-student relationship. The results of the SEM showed that parental marital conflict not only predicts adolescent IGD directly, but also through the mediation effects of deviant peer affiliation and teacher-student relationship. Additionally, deviant peer affiliation and teacher-student relationship not only play an independent but also a sequential mediating effect in the relationship between parental marital conflict and IGD. The relationship between parental marital conflict and IGD is mediated by deviant peer affiliation and teacher-student relationship, which has potential prevention and intervention value for adolescent IGD.

Abstract	BackgroundNumerous studies have suggested that ferroptosis plays a significant role in the development of polycystic ovary syndrome (PCOS), but the mechanism remains unclear.MethodsIn this study, we explored the role of ferroptosis-related genes in the pathogenesis of PCOS using a comprehensive bioinformatics method. First, we downloaded several Gene Expression Omnibus (GEO) datasets and combined them into a meta-GEO dataset. Differential expression analysis was performed to screen for significant ferroptosis-related genes between the normal and PCOS samples. The least absolute shrinkage selection operator regression and support vector machine–recursive feature elimination were used to select the best signs to construct a PCOS diagnostic model. Receiver operating characteristic curve analysis and decision curve analysis were applied to test the performance of the model. Finally, a ceRNA network-related ferroptosis gene was constructed.ResultsFive genes, namely, NOX1, ACVR1B, PHF21A, FTL, and GALNT14, were identified from 10 differentially expressed ferroptosis-related genes to construct a PCOS diagnostic model. Finally, a ceRNA network including 117 lncRNAs, 67 miRNAs, and five ferroptosis-related genes was constructed.ConclusionOur study identified five ferroptosis-related genes that may be involved in the pathogenesis of PCOS, which may provide a novel perspective for the clinical diagnosis and treatment of PCOS.

Abstract	As an extension of traditional bullying, cyberbullying emerges with the increasing popularity of the internet, and seriously affects the health of students. However, fewer studies have explored the potential influencing mechanisms of cyberbullying victimization from a positive psychology perspective. Therefore, based on the positive youth development theory, this study will explore the potential mediator and moderator in the relationship between positive youth development (PYD) attributes and cyberbullying victimization through a longitudinal design. 719 students (Mage = 15.95 years, SD = 0.76, 45.2% boy) participated in the study and completed self-report questionnaires on relevant variables. The result found that students' level of PYD significantly and negatively predicted the level of cyberbullying victimization. Meanwhile, SEM analysis showed that PYD influenced individuals' cyberbullying victimization by affecting their internet gaming disorder (IGD), while depression levels moderated the relationship between PYD and IGD. This study examines cyberbullying victimization from a positive psychology orientation, with potential prevention and intervention value.
