    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 Previously, we developed a highly efficient transverse mode instability model by integrating stimulated thermal Rayleigh scattering and quasi-3D fiber amplifier models, enabling the consideration of the 3D gain saturation effect, with its accuracy verified by reasonable fit to experimental data. Bend loss was however ignored. Higher-order-mode bend loss can be very high especially for fibers with core diameters below 25µm and is sensitive to the local heat load. By using a FEM mode solver to account for bend loss and local heat-load-induced bend loss reduction, the transverse mode instability threshold is studied in detail, resulting in some interesting new insights.

    Abstract Background: Prominent ears were the most common auricular deformity. Different surgical techniques, such as cartilage-cutting techniques and suturing techniques, are available for treatment. The horizontal mattress suture technique, represented by the Mustard technique, is widely accepted, while the vertical mattress suture technique is rarely discussed in otoplasty.
    Method: A total of 104 cases of prominent ear deformities were treated from January 2017 to December 2020. Several hypothetical "tension bands" perpendicular to the natural curvature of the antihelix were introduced for the surgical design and determination of the position of the antihelix fixation, and vertical mattress sutures were placed accordingly for the auricular cartilage fixation.
    Result: Follow-up ranged from 3 months to 2 years. No complications, such as hematoma, infection, or poor wound healing, were observed. Three patients had recurrence within two months post operation, and one complained about the overfolded antihelix. Three cases had suture exposure, but the shape of the auricle was not affected after suture removal. The surgical result was evaluated according to the overall shape of the auricle, including the shape of the antihelix, the improvement of the prominent, the surgical marks, and the bilateral symmetry. A total of 98 patients (94.23%) rated the results as "very satisfactory" or "satisfactory".
    Conclusion: The vertical mattress suture applied as "tension band fixation" could provide stable cartilage fixation with the natural appearance of the antihelix formation. In addition, the technique could fit a wide range of indications with a low risk of complication and reoccurrence.

    Abstract Music and dance videos have been popular among researchers in recent years. Music is one of the most important forms of human communication; it carries a wealth of emotional information, and it is studied using computer tools. In the feature engineering process, most present machine learning approaches suffer from information loss or insufficient extracted features despite the relevance of computer interface and multimedia technologies in sound and music matching tasks. Multifeature fusion is widely utilized in education, aerospace, intelligent transportation, biomedicine, and other fields, and it plays a critical part in how humans get information. In this research, we offer an effective simulation method for matching dance technique movements with music based on multifeature fusion. The initial step is to use music beat extraction theory to segment the synchronized dance movements and music data, then locate mutation points in the music, and dynamically update the pheromones based on the merits of the dance motions. The audio feature sequence is obtained by extracting audio features from the dancing video's accompanying music. Then, we combine the two sequences to create an entropy value sequence based on audio variations. By comparing the consistency of several approaches for optimizing dance movement simulation trials, the optimized simulation method described in this research has an average consistency of 87%, indicating a high consistency. As a result, even though the background and the subject are readily confused, the algorithm in this research can keep a consistent recognition rate for more complicated dance background music, and the approach in this study can still guarantee a certain accuracy rate.

    Abstract Quantifying the spatial organization of human settlements is fundamental to understanding the complexity of urban systems. However, the quantitative patterns of the distribution of villages, towns, and cities that lie between random and regular, are still largely unknown. Here, by analyzing the geographic location of settlements in diverse regions, we show that the apparently complex urban systems can be characterized by disordered hyperuniformity (with small density fluctuations), an intriguing pattern that has been identified in many physical and biological systems, but has rarely been documented in socio-economic systems. By introducing the mechanisms of spatial matching and competition, we develop a growth model that shows how settlements evolve towards hyperuniformity. Our model also predicts the heavy-tail population distribution across settlements, in agreement with empirical observations. These results provide insights into the self-organization of cities, and reveal the universality of spatial organization shared by social, physical, and biological systems.

    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.
