Abstract	Seamounts are geographically isolated, substrate-rich and highly heterogenetic habitats, where little is known about the population shifts and assembly mechanism of the local microbial communities. In this study, microbes in the sediments across a series of seamounts along the island arc of the Yap and Mariana trenches were investigated via high-throughput sequencing. Clear distance-decay distribution was revealed in a horizontal scale among different seamounts, and in a vertical scale from the summit to the base of seamounts. This biogeography was mainly driven by the deterministic process, although the contribution of stochastic process progressively increased from the summit to the base of seamounts. In addition, higher levels of prokaryotic abundance, diversity, and niche width in the seamounts than the Challenger Deep were observed as well, further proved seamounts as deep oasis for microbes. Spatial heterogeneity of microbial community connectivity among/intra seamounts was demonstrated as well, might be shaped simultaneously by the hydrogeographic variables and the limitation of ocean current dispersal. Overall, this study contributed new insights into the mechanism controlling the microbial community assembly, provide base for future exploration of ecological functions of microbes living in this extreme biosphere.

Abstract	Enterprises with diverse life cycles possess distinct survival and operational laws. Hence, it is crucial to comprehend whether all these enterprises can proficiently engage in green innovation under the guidance of carbon emissions trading (CET). This study leverages the quasi-natural experiment of CET policy, employing panel data encompassing A-share listed companies in Shanghai and Shenzhen spanning from 2008 to 2020. Through the application of the triple difference model, the research examines the influence of CET policy on the green innovation endeavors of enterprises characterized by various life cycles. The research outcomes reveal the following: 1) CET policy significantly impacts the green innovation of mature enterprises, and contributes to the enrichment of the quality of their green innovation endeavors. 2) Due to limitations pertaining to financing constraints and business expansion, CET policy fails to foster green innovation within the growth and decline phases of enterprises. 3) Government subsidies can overturn the unfavorable position of growth-stage enterprises in carbon emissions trading and propel them towards heightened green innovation. However, government subsidies do not yield a substantial moderating effect on the green innovation endeavors of maturity-stage enterprises. Simultaneously, even if declining-phase enterprises are subjected to government subsidies, these subsidies do not reverse their innovation disadvantage in carbon emissions rights trading. In addition, we also found that in areas with heightened public awareness of environmental protection and state-owned enterprises, the positive regulatory effect of government subsidies is more significant. The findings derived from this study bestow invaluable insights for decision-makers striving to optimize the implementation of the CET policy and effectively allocate government subsidies.

Abstract	Postdocs encounter numerous hurdles in terms of their professional survival and academic development, as a result of institutional reform and the prevailing academic environment. These challenges significantly impact their job satisfaction, which in turn plays a crucial role in shaping their scientific research career trajectory. To facilitate the advancement of relevant systems and augment the job satisfaction of postdocs, this study employs the 2020 Nature Global Postdoctoral Survey data to conduct a comprehensive analysis. Utilizing descriptive statistics, correlation analysis, and regression analysis, the impact of job characteristic elements on postdoctoral job satisfaction was examined within the theoretical framework of the Job Requirements-Resources (JD-R) model, as well as the mechanisms by which job characteristic elements impact postdoctoral job satisfaction. It was found that job demands and job resources negatively and positively predicted postdoctoral job satisfaction, respectively, with job burnout and job engagement playing a partial mediating role. Job demands can drive postdocs to develop negative coping psychology and limit the motivating effect of job resources on job engagement; job resources can act as a buffer to reduce the probability of postdocs experiencing job burnout as a result of job demands. The aforementioned findings generally support the applicability of the JD-R model to postdocs, theoretically revealing the intrinsic psychological mechanisms by which job characteristics influence postdoctoral job satisfaction and providing theoretical supplements and practical references for postdoctoral training and management.

Abstract	The impeller, regarded as the central component of a centrifugal pump, plays a pivotal role in dictating overall performance. Overcoming challenges arising from the complexity of design parameters and the time-intensive nature of the design process has been a persistent obstacle to widespread adoption. In this study, we integrated ANSYS-CFX 2023 software with innovative inverse design techniques to optimize the impeller design within a centrifugal pump system. Our investigation reveals groundbreaking insights, highlighting the significant influence of both blade load and shaft surface geometry on impeller performance. Notably, through load optimization, substantial enhancements in centrifugal pump efficiency were achieved, demonstrating improvements of 1.8% and 1.7% under flow conditions of 1.0 Q and 0.8 Q, respectively. Further, the efficiency gains of 0.44% and 0.36% were achieved in their corresponding flow conditions. The optimization of blade load and shaft surface configuration notably facilitated a more homogenized internal flow pattern within the impeller. These novel findings contribute substantively to the theoretical foundations underpinning centrifugal pump impeller design, offering engineers a valuable reference to elevate their performance. Our utilization of ANSYS-CFX software in conjunction with inverse design methodologies showcases a promising avenue for advancing impeller design, ultimately culminating in superior efficiency and performance for centrifugal pumps.

Abstract	In the realm of existing intelligent drip irrigation control systems, traditional PID control encounters challenges in delivering satisfactory control outcomes, primarily owing to issues related to non-linearity, time-varying behavior, and hysteresis. In order to solve the problem of the unstable operation of the drip irrigation system in an intelligent irrigation system, this paper proposes chaotic beetle swarm optimization (CBSO) based on the BAS (beetle antennae search) longicorn search algorithm, with inertial weights, variable learning factors, and logistic chaos initialization improving global search capabilities. This was accomplished by formulating the optimization objective, which involved integrating the control input’s time integral term, the square term, and the absolute value of the error. Subsequently, PID parameter tuning was performed. In order to verify the actual effect of the CBSO algorithm on the PID drip irrigation control system, MATLAB was used to simulate and compare PID control optimized by the GA algorithm, PSO algorithm, and BSO (beetle search optimization) algorithm. The results show that PID control based on CBSO optimization has a short response time, small overshoot, and no oscillation in the steady state process. The performance of the controller is improved, which provides a basis for PID parameter setting for a drip irrigation control system.

Abstract	Rhamnosyl Icariside II is a rare secondary flavonoid glycoside isolated from Epimedium L. plants. It has better stability and physiological activity than the primary flavonoid glycosides of Epimedium L., therefore, conversion of the primary flavonoid glycoside into Rhamnosyl Icariside II would be desirable. In this study, a method for the enzymatic production of Rhamnosyl Icariside II from the total flavonoids of Epimedium wushanense was established, and the conditions were optimized. Six commercial enzymes were screened, and the reaction conditions for the best enzyme were optimized. Snailase was the most effective hydrolase, and the highest yield was obtained under the optimized conditions. To facilitate industrial production of Rhamnosyl Icariside II, a scaled-up pilot test was performed. The reaction solution was extracted with n-butanol to obtain the Rhamnosyl Icariside II crude product, which was then subjected to silica gel column chromatography and preparative chromatography. Finally, a product of Rhamnosyl Icariside II with purity of 99.1 % was achieved, in a total yield of 46.8 %. Compared to direct extraction and acid hydrolysis, this method improves the product yield and purity, which is of great significance for the large-scale production of Rhamnosyl Icariside II. This study provides a basis for the physiological activity study of Rhamnosyl Icariside II, and offers possibilities for future applications in the healthcare sector.

Abstract	Rapid business expansion of various companies has placed growing demand on office desktops recent decades. However, improper evaluation of system performance and inexplicit awareness of practical use conditions often hamper the efforts to make a consummate selection among multiple alternatives. From the perspective of end users, to optimize the evaluation process of desktop performance in centralized procurement, we present CpsMark+, a coherent benchmark system that evaluates office desktop performance based on simulated user experience. Specifically, CpsMark+ includes scenario-oriented workloads portraying representative user behaviors modeled from the cooperative workflow in modern office routines, and flexibly adapted metrics properly reflecting end-user experience according to different task types. The contrast experiment between state-of-the-art benchmarks demonstrates high sensitivity of CpsMark+ to various hardware components, e.g., CPU, and high repeatability with a Coefficient of Variation less than 3%. In a practical case study, we also demonstrate the effectiveness of CpsMark+ in simulating user experience of tested computer systems under modern office-oriented scenarios for improving the quality of office desktop performance evaluation in centralized procurement.

Abstract	Using data from the China Education Panel Survey (CEPS), this study empirically examines the association between internal migration and child health through an investigation of health disparities between migrant children and left-behind children in China. The results show that, in comparison with being left behind, migrating with parents significantly improves children’s self-reported health, height-for-age z-score (HAZ) and BMI-for-age z-score (BAZ), and reduces their frequency of sickness. These findings remain robust to a suite of robustness checks. Furthermore, the health effects of internal migration are more prominent for children with a rural hukou compared with urban ones. Although migrant children are more likely to experience teacher discrimination, they have higher levels of parental care, family relationships, and peer relationships relative to their left-behind counterparts, which indicates possible mechanisms behind the association between children’s migration and health. Our findings underline the importance of policy improvement and evidence-based interventions aiming at reducing involuntary parent-child separation and facilitating the development in health of disadvantaged children in developing countries like China.
