    Abstract Despite the significance of grit and motivational regulation strategies (MRS) to language learning, limited research has been conducted on their longitudinal interplay. The present study explores the relationship between these two constructs in an English as a second language (L2) learning context through a longitudinal design. This study utilizes repeated measures of L2 grit and MRS at two time points (T1 and T2) to investigate the direction of influence between them and proposes and evaluates four models: an autoregressive model, two unidirectional models, and a bidirectional model. Using questionnaire data from 205 Chinese university students to evaluate the models, results from model assessment revealed that L2 grit at T1 positively predicted L2 grit at T2 and that MRS at T1 positively predicted MRS at T2. While L2 grit showed stability, MRS developed over time. The unidirectional model with L2 grit at T1 as a predictor of MRS at T2 was identified as the model of best fit, indicating that L2 grit at an earlier time unidirectionally influenced MRS at a later time. Based on these findings, we conclude that there is a unidirectional influence between L2 grit and MRS: the former plays an influential role in shaping MRS in L2 learning over time. Implications and recommendations for future research are discussed. This study contributes to a deeper understanding of the dynamics between the two constructs, which in turn impacts language learning persistence and success, offering valuable insights for educators, policymakers, and researchers striving to optimize language learning environments and interventions.

    Abstract Equivalent sound level (Leq), sound pressure level (SPL) and fundamental frequency (F0) were analyzed in the stage speech of six Kunqu Opera roles, Young woman, Old woman, Young man, Old man, Colorful face and Clown. The roles differ in gender, age, personality and phonation types. Differences among emotions (neutral, sad, angry and happy), singers and roles were examined. For most roles, more similarities were observed between neutral and sad stage speech and between angry and happy stage speeches. In most cases, the latter group showed higher Leq, mean SPL and Mean F0 and larger standard deviation (SD) of SPL difference than the former. Some parameters, such as SD of SPL, the mean of SPL difference and the difference between Leq and mean SPL, also showed the intra-group differences.Young woman role, Young man role and Old woman role were similar in some parameters. Colorful face role and Old man role showed a lot of similarities. Clown role showed the least similarities with the other roles. With regard to gender and age, young roles showed smaller SPL difference, larger correlation coefficient between F0 and SPL and larger mean SPL differences between emotions than old roles; female roles had greater parameter consistency and larger correlation coefficient between F0 and SPL than male roles. The personality and phonation types also effected the characteristics of loudness and pitch. This study showed the importance of speakers' characteristics in emotional speech analysis.

    Abstract This paper rigorously addresses the intricate control demands of high-speed, high-pressure, wide adjustable speed range, and high energy utilization efficiency required in hydrogen fuel cell centrifugal compressor, with a focus on the speed control of 40,000 RPM permanent magnet synchronous motors (PMSMs). An improved second-order super twisting sliding mode control (STSMC) strategy is proposed to enhance system stability and robustness by integrating the beetle antennae search (BAS) algorithm and grey wolf optimization (GWO) algorithm. The global search capability of BAS is used to improve the local optima issues of GWO, and then the improved GWO algorithm is utilized to address the issues related to parameter selection and convergence speed inherent in the STSMC. Theoretical validity of the proposed strategy is asserted through Quadratic Lyapunov Function, and its practicality is affirmed by thorough simulation. Comparative analyses are conducted with PI controller, traditional Sliding Mode Controller (SMC), and standard Super-Twisting Sliding Mode Controller (ST) under several case studies to show the superiority of the propose STSMC.

    Abstract The aberrant expression of Forkhead box M1 (FOXM1) has been associated with the pathological processes of Parkinson's disease (PD), but the upstream and downstream regulators remain poorly understood. This study sought to examine the underlying mechanism of FOXM1 in dopaminergic neuron injury in PD. Bioinformatics analysis was conducted to pinpoint the differential expression of FOXM1, which was verified in the nigral tissues of rotenone-lesioned mice and dopaminergic neuron MN9D cells. Interactions among SP1, FOXM1, SNAI2, and CXCL12 were analyzed. To evaluate their effects on dopaminergic neuron injury, the lentiviral vector-mediated manipulation of FOXM1, SP1, and CXCL12 was introduced in rotenone-lesioned mice and MN9D cells. SP1, FOXM1, SNAI2, and CXCL12 abundant expression occurred in rotenone-lesioned mice and MN9D cells. Silencing of FOXM1 delayed the rotenone-induced dopaminergic neuron injury in vitro. Mechanistically, SP1 was an upstream transcription factor of FOXM1 and upregulated FOXM1 expression, leading to increased SNAI2 and CXCL12 expression. In vivo, data confirmed that SP1 promoted dopaminergic neuron injury by activating the FOXM1/SNAI2/CXCL12 axis. Our data indicate that SP1 silencing has neuroprotective effects on dopaminergic neurons, which is dependent upon the inactivated FOXM1/SNAI2/CXCL12 axis.

    Abstract ObjectiveThe present study aimed to explore the value of a digital management system based on micro digital imaging technology for the medical records of patients with cerebral hemorrhage.MethodsA total of 540 patients with intracerebral hemorrhage diagnosed and treated in the hospital from November 2016 to November 2019 were selected as the subjects of this study. A digital management system based on micro digital imaging technology was used to establish how to handle the medical records of these patients.ResultsThe medical record management process of patients with cerebral hemorrhage comprises five modules: medical record editing, medical record querying, medical record borrowing management, statistical analysis, and system maintenance. The purpose of these is to manage and store digitalised medical records for patients, present the most useful information on the first page of the medical records, monitor the safety of the medical records, and enable real-time data sharing.ConclusionEstablishing a digital management system based on micro digital imaging technology for the medical records of patients with cerebral hemorrhage can effectively enable the preservation and use of these documents. It improves information management, such as data sharing, security, and the overall level of information. This is worth promoting.

    Abstract Abstract This paper uses the bibliometric method to analyze the basic characteristics and disciplinary knowledge structure of family-friendly policy research, as well as research hotspots and trends. The basic data source is the literature in the Web of Science Core Collection from 1985 to 2022. The following findings were obtained. First, the number of publications and citations in this field have increased exponentially, with scholars and research institutions from the US dominating the field of family-friendly policy research. Second, family-friendly policy research has been concentrated in the fields of management, sociology, and psychology, with a gradual trend toward cross-disciplinary integration, but a core group of authors has yet to be formed. Third, most of the family-friendly policy research has been conducted at the organizational level to explore the impact of family-friendly policies, with married women as the main research object. Finally, current family-friendly policy research focuses on policy fairness, childcare services, employee satisfaction, and work flexibility. Future research should focus on the dynamics of family-friendly policies and the empirical analysis of cross-level integration to improve the matching of policies with employee orientation. This study fills an analytical gap in the integration of family-friendly policies and scientometrics, proposes an expandable field of family-friendly policy research and research methods, and provides references and insights for future family-friendly policy research and practice.

    Abstract Abstract The Luojia 1–01 (LJ1-01) night lighting satellite's superior spatial information capture capability provides conditions for accurate assessment of regional wealth distribution inequality (RWDI) at a small scale. This paper evaluated the wealth Gini coefficient (WGC) of 2,853 counties and 31 provinces in mainland China to establish a comprehensive picture of inequalities at county-level regions in China as a whole, using data from LJ1-01 and the Suomi National Polar Orbiter Partnership Visible Infrared Imaging Radiometer Suite (NPP-VIIRS). The WGC values (LJ-Gini) calculated by the LJ1-01 data are always higher than those (NPP-Gini) based on NPP-VIIRS, and the mean of the ratio between them is 1.7. Compared with NPP-Gini, LJ-Gini showed sensitivity to low RWDI areas. The average county and provincial LJ-Gini are statistically consistent, 0.77 and 0.78; County LJ-Gini’s volatility is significantly higher than that of the provincial LJ-Gini, with standard deviations (SD) 0.13 and 0.096. The differences of RWDI in the regions within some provinces are more significant than in other provinces. For example, the SD of Tibet is 0.31, while all provinces' average SD is 0.13. In addition, this paper establishes a grading criterion based on the normal distribution abstracted from provincial LJ-Gini to reflect the corresponding relationship between the LJ-Gini value and the five inequality ranks. Totally, RWDI demonstrates heterogeneity at various spatial scales and regions, and it correlates negatively with economic development. The superior performance of LJ1-01 data in evaluating county-level RWDI demonstrates its potential to evaluate RWDI on a smaller scale, such as communities and streets.

    Abstract Objective: To investigate the effect of intensity-modulated radiotherapy combined with local hyperthermia on Mortalin expression in advanced liver cancer lesions and its relationship with cell proliferation and EMT. Methods: A total of 82 patients with advanced liver cancer who were treated in this hospital between February 2016 and September 2017 were chosen as the research subjects, and the therapeutic regimens were reviewed and used to divide these patients into the control group (n=43) who received intensity-modulated radiotherapy and the combined treatment group (n=39) who received intensity-modulated radiotherapy combined with local hyperthermia. Abdominal puncture was done after treatment to obtain liver cancer tissue samples, and the differences in Mortalin gene, cell proliferation gene and EMT gene expression in tissues were compared. Results: After treatment, Mortalin mRNA expression in liver cancer tissues of combined treatment group was lower than that of control group; Fbxw7 mRNA expression in liver cancer tissues was higher than that of control group whereas NCX1, PRMT5 and XBP1S mRNA expression were lower than those of control group; Twist, ZEB-1, ZEB-2, Snail and HOXB7 mRNA expression in liver cancer tissues were lower than those of control group. Pearson test showed that the Mortalin gene expression in liver cancer tissues was directly correlated with cell proliferation genes and EMT genes. Conclusion: Intensity-modulated radiotherapy combined with local hyperthermia can effectively reduce Mortalin gene expression, and further optimize patients' condition by inhibiting hepatic cell proliferation, EMT activity and other pathways.

    Abstract Objective: To study the correlation of sST2 and Fascin contents in malignant pleural effusion with malignant proliferation and invasion of cancer cells. Methods: Lung cancer patients with malignant pleural effusion who were treated in the Fourth (Xingyuan) Hospital of Yulin between November 2014 and November 2016 were retrospectively analyzed and selected as the malignant group of the research, and patients with heart failure, hypoalbuminemia and pleural effusion during the same period were selected as the control group. The pleural effusion was collected from the two groups of patients to determine the contents of sST2 and Fascin, and the lung cancer lesions and adjacent lesions were collected from the malignant group to determine the mRNA expression of the cell proliferation genes and invasion genes. Results: sST2 and Fascin contents in pleural effusion of malignant group were significantly higher than those of control group; KI-67, BCL2, N-cadherin and MMP9 mRNA expression in lung cancer lesions were significantly higher than those in adjacent lesions whereas MTS1, LKB1, Bin-1, TMSG-1 and E-cadherin mRNA expression were significantly lower than those in adjacent lesions; KI-67 and BCL2 mRNA expression in lung cancer lesions with high sST2 content were significantly higher than those in lung cancer lesions with low sST2 content whereas MTS1 and LKB1 mRNA expression were significantly lower than those in lung cancer lesions with low sST2 content; Bin-1, TMSG-1 and E-cadherin mRNA expression in lung cancer lesions with high Fascin content were significantly lower than those in lung cancer lesions with low Fascin content whereas N-cadherin and MMP9 mRNA expression were significantly higher than those in lung cancer lesions with low Fascin content. Conclusions: The increase of sST and Fascin in malignant pleural effusion are related to the aggravation of cancer cell proliferation and invasion respectively.
