This research delves into the intricate relationship between cellular and molecular adaptations and their implications in educational advancements among adolescents engaged in sports dance routines within the framework of physical education settings. Utilizing a randomized controlled trial involving 120 participants (with 60 in the experimental group and 60 in the control group), the study spanned a 16-week intervention period. The assessment protocols were comprehensive, covering cellular and molecular indicators (biomechanical properties of muscle fibers, cardiac health markers), as well as educational outcomes (deliberate skill acquisition, academic engagement, and innovation in movement expression). Notably, the experimental group showed marked advancements across various parameters: an increase in cardiac health indicators (peak oxygen consumption, VO2max improvement: 21.3%, p < 0.001), enhanced biomechanical properties (muscle elasticity improved by 50%, muscle strength increased by 45%, p < 0.001), and an improvement in motor skills (technical proficiency rose by 41.5%, coordination by 48.3%, p < 0.001). There was a striking link between these cellular and molecular adaptations and the educational outcomes (r = 0.721–0.845, p < 0.01), which was further confirmed by regression analysis indicating cardiac metabolic fitness as a pivotal predictor of technical dexterity (β = 0.384, p < 0.001). The adolescents in the experimental group also exhibited considerable gains in mastering complex movement sequences (56.7% improvement, integration of performance: 55.3%, p < 0.001) and in academic engagement (motivation increased by 46.2%, collaborative interaction: 47.7%, p < 0.001). A pivotal “adaptive window” identified between the 8th and 12th week of training, suggested the most fruitful times for intervention to yield optimal outcomes. These results provide solid evidence that structured sports dance training is beneficial for both biomechanical development and educational success in adolescents, providing valuable guidance for physical education curriculum design and implementation.

Sun Yu — 2025-02-13

In 2019, a sudden outbreak of novel coronavirus disease swept the world, seriously affecting education and teaching. Most universities around the world have adopted a “learning without classes” model, which is dominated by online teaching. Up to now, this teaching model under the normalization of the epidemic has been popularized all over the world. However, the evaluation of online teaching quality and the weight of influencing factors have become difficult points in measuring teaching quality, that is, the factors and weights affecting online teaching are problems that need to be studied and solved urgently. This study takes online physical education (PE) teaching in Chinese universities as the research object. While traditional research often centers on teaching evaluation methods, this research innovatively integrates biomechanics into the study. By analyzing the relevant research literature, it proposes a weight evaluation method for online PE teaching index in universities based on analytic hierarchy process (AHP)-entropy method-fuzzy comprehensive evaluation method. This method is actually a new teaching evaluation model that combines the subjective and objective weighting method with the fuzzy evaluation method. Integrating biomechanics offers a novel perspective on online PE. It aids in assessing students' exercise effectiveness and optimizing online educational resources. Advanced video analysis and motion capture can precisely measure students' joint angles, limb movement trajectories, and muscle activation patterns during exercises. This enables accurate evaluation of movement standardization. By comparing with optimal biomechanical models, teachers can provide targeted guidance, enhancing exercise effectiveness and reducing injury risks. In teaching video creation, incorporating biomechanical principles helps students understand the scientific basis of movements. For instance, in a basketball shooting tutorial, explaining the arm, wrist, and finger biomechanics can improve students' understanding and performance. Moreover, biomechanical simulation technology can create virtual sports scenes, enriching the online learning experience by allowing students to explore environmental impacts on body mechanics. We applied the method to the weight analysis of online PE teaching index in Chinese universities, and demonstrated that the method has good applicability. More importantly, we have condensed the conclusions of this research into practical countermeasures, and put forward strategies to improve the quality of online PE teaching from the macro level and the subjective research level. This research achieves innovation at the application level, improvement at the theoretical level and focus at the practical level. The research results can help Chinese universities to improve the quality of current online PE teaching, and even provide experience and reference for formulating relevant measures for international online teaching.

Cognitive linguistic analysis of spatial verbs in “Zuo Zhuan” and exploration of the spatiotemporal relationship bioinformatically

Jia Xu — 2025-02-13

In recent years, the digitalization of ancient books has revitalized traditional works and highlighted the “humanistic” dimension of digitalization. This article employs the SikuBERT pre-training model, which is tailored for natural language processing in classical Chinese texts, and forges an innovative connection with the realm of biomechanics, to conduct a comprehensive analysis of spatial verbs in the pre-Qin dynasty text Zuo Zhuan. The analysis encompasses detailed annotation, quantitative analysis, automatic recognition, and evaluation of spatial verbs, culminating in the creation of a digital knowledge base for spatial verbs in Zuo Zhuan. The study identifies four main types of high-frequency spatial verbs in Zuo Zhuan: Motion, state, existence, and direction. To enhance theoretical depth, this classification is grounded in cognitive linguistic theory, which explains the semantic connotations and cognitive basis of each verb type. Motion verbs, are closely linked to the representation of dynamic spatiotemporal contexts, particularly in describing human movement patterns and behaviors, invoking principles from biomechanics such as kinematics and dynamics. These verbs can be integrated with biomechanical concepts like trajectory analysis and mechanical models to understand how ancient humans engaged in dynamic activities within specific spaces. State and existence verbs emphasize static relationships, while directional verbs highlight the guiding nature of movement trajectories, which can be further explored through concepts of displacement and velocity in biomechanics. These verb types interact to construct the spatiotemporal framework of the text, demonstrating how language encodes complex spatial and temporal relationships. Moreover, the study investigates the interactive mechanisms of the four verb types in language use, analyzing how they collectively construct the spatiotemporal context of ancient texts, thereby enhancing our understanding of narrative techniques in pre-Qin literature. For instance, motion verbs often act as the primary drivers of narrative progression, while state verbs provide contextual stability, existence verbs denote presence, and directional verbs guide interpretative focus. Quantitatively, the study examines the characteristics of these verbs from three dimensions: temporal-quantitative relations, behavioral-quantitative relations, and scene-component relations. The findings reveal distinct quantitative features among the four types, with motion verbs exhibiting the highest diversity and quantity. This nuanced exploration not only contributes to the re-interpretation of pre-Qin dynasty texts but also strengthens the ability to deconstruct and analyze digitalized texts from this period, thereby advancing the field of classical Chinese digital humanities. By integrating a biomechanical perspective, this study further explores the application of spatial verbs in describing human movement behaviors, utilizing biomechanical models to analyze the efficiency and postural changes of ancient humans in specific environments, revealing the deep connections between language expression and human activity. This interdisciplinary perspective enriches our understanding of ancient culture and provides a new methodological framework for research in modern humanities.

Research on cellular and molecular biomechanics-inspired enhancement of visual communication in medical product design via graphic processing algorithm optimization

Junlin Li — 2025-02-13

The computational complexity of graphic processing algorithms is increasing under the continuous development of information technology. At the same time, the medical product design field puts forward higher and higher requirements on the visual communication effect of related images. In this study, the up-sampling optimization algorithm and the threshold filtering algorithm are proposed to optimize the Laplacian graphics processing algorithm. Notably, in the threshold filtering algorithm, the Triangle algorithm is employed to address the grayscale of images pertinent to medical product design. The perception of the grayscale and binarized images by the human visual system triggers neural signals that propagate and can influence intracellular processes. When observing medical product images, neurons fire, leading to the release of neurotransmitters like glutamate. These neurotransmitters bind to receptors on cells, initiating signaling cascades such as the MAPK pathway. This pathway can affect gene expression and protein synthesis, potentially modulating cellular functions related to perception and response to the medical product design. The results show that the optimized graphical processing algorithms in this paper outperform the comparison algorithms in the CLBLAS library, and the floating-point computational values of the Laplacian algorithm are much higher than the comparison algorithms in the face of the large-scale input parameters. The Laplacian algorithm is able to accurately stitch and process the captured 2D images of cellular microtubules related to the design of the medical products in a guaranteed high efficiency (31 min), and The Laplacian algorithm was able to achieve an average subjective score of 0.856 for the visual communication of medical product design images. This graphic processing algorithm can generate images of superior perceptual quality, which holds substantial significance for augmenting the visual communication effect of medical product design images and considering the underlying cellular molecular biomechanical responses.

TIGNN-RL: Enabling time-sensitive and context-aware intelligent decision-making with dynamic graphs in recommender systems and biomechanics knowledge

Hui Yang — 2025-02-13

Intelligent decision-making in dynamic recommender systems is crucial for capturing temporal user preferences and optimizing long-term user satisfaction. Traditional recommender systems often rely on static modeling, neglecting the temporal dynamics of user-item interactions. To address this limitation, we propose a novel framework, Temporal Interpretability Graph Neural Network with Reinforcement Learning (TIGNN-RL), which integrates dynamic graph neural networks (DGNNs) and Proximal Policy Optimization (PPO) to optimize personalized recommendations. Specifically, our method models user-item interactions as dynamic graphs and utilizes temporal interpretability modules to encode both temporal features and node-specific static features. The temporal interpretability module assigns time-aware and interactions weights to user-item, enabling more time-sensitive and explainable dynamic embeddings. This TIGNN dynamic graph sequential embedding is processed by some LSTM modules to be used as the state of the deep reinforcement learning agent and states. We take a joint approach to training, earn graph embeddings that enable better PPO policy. To evaluate the proposed framework, we conduct experiments on three benchmark datasets: Last.fm 1K, MovieLens 1M, and Amazon Product Review. Results show that TIGNN-RL outperforms state-of-the-art baselines, which use GNNs for augmenting DRL-based RS, in terms of accuracy (NDCG@K) and diversity (ILD@K@K), demonstrating its effectiveness in dynamic and interpretable recommendation scenarios. In this research, some biomechanics knowledge is integrated to further enhance the understanding and application of the proposed framework in scenarios where user behavior is influenced by physical factors.

Jun Yan — 2025-02-13

Gut microorganisms have become a hot spot of scientific research at home and abroad in recent years, in which the study of correlation between microbial community structure and intestinal diseases can provide theoretical basis for biopharmaceuticals for intestinal diseases. In this paper, we constructed in vitro simulated gastric and small intestinal digestion models, as well as large intestinal microbial fermentation models, to study the relative molecular weight and spatial structure changes of β-glucan in simulated gastric and small intestinal regions, and investigated the degradation of β-glucan in simulated large intestinal regions as well as its effects on intestinal microorganisms. In addition to the biochemical and metabolic aspects, integrating biomechanical principles into this research can enhance our understanding of how gut microbes interact with the host’s physiological environment. For instance, the biomechanical properties of the gut—such as motility, peristalsis, and the mechanical forces exerted on microbial populations—can influence the distribution and activity of gut microorganisms. Understanding these biomechanical factors may reveal how they affect the degradation of β-glucan and the overall microbial community structure. Secondly, fecal microorganisms from different batches of mice and different individuals of human volunteers were collected as inoculum for fermentation of β-glucan, to analyze the main microorganisms that stably responded to β-glucan in different batches of fermentation experiments as well as in gut microorganisms from different individuals and to further investigate the metabolic changes, metabolic pathways as well as the biomarkers of β-glucan in the simulated large intestine. L. murinus Mic06, L. murinus Mic07, L. murinus Mic08, and L. murinus Mic094 were validated to be able to utilize β-glucan and produce a small amount of reducing sugars in all four species of Lactobacillus intestinalis in mice, and there was no significant difference in the ability to utilize them; All nine species of human enterobacteriophages were able to utilize β-glucan and produce reducing sugars, with B. xylanisolvens Bac02 and B. koreensis Bac08 having a significantly greater ability to utilize β-glucan. This study contributes to a deeper understanding of gut disease-associated flora and provides strong support for the use of the gut microbiome for multidisease classification. Additionally, considering biomechanical aspects may lead to novel insights into the interactions between gut microbes and host physiology, enhancing the development of targeted biopharmaceuticals.

To maintain and enhance students’ learning motivation and interest, more effective individualized teaching is needed. This study focuses on students’ individualized knowledge structure, tracking the differences in sports skills among different types of students, and designing a sports game model based on sports games. A Bayesian network model was used to model learners’ knowledge and establish an adaptive badminton competition mode. Then, a new feature intersection method is studied, and a method for deep knowledge tracking is established using feature embedding and attention mechanisms. Finally, on this basis, this method is combined with adaptive learning methods to establish a badminton game model based on adaptive learning and improved deep knowledge tracking. Additionally, this study explores the biological principles underlying sports skill learning. When students learn badminton skills.

Motion capture technology can capture the kinematic data of students’ badminton movements, such as joint angles and limb velocities. By integrating this data with the biological feedback, we can optimize learning outcomes by enabling more precise identification of skill deficiencies and more effective remediation. The experiment shows that the acceleration Z is the maximum, approximately 100. The acceleration of X is the smallest, approximately between −200 and 200. The most unstable is the acceleration Y. After positive compensation, the value of the adaptive quantization parameter cascade algorithm increases. And the quantized adaptive quantization parameter cascade algorithm value does not have a significant impact on the evaluation of the reconstructed image. The average values of each scale and sub dimension are above 0.70, and the constituent reliability values are above 0.90, indicating that the internal quality of each scale is good. And the internal consistency between questions is also good, all of which have passed the validity test.

This work explores the biomechanical characteristics of key actions in fencing techniques using motion capture and biomechanical analysis technology, aiming to provide scientific evidence for athlete training and performance. The work combines eight infrared high-speed cameras with the Delsys surface Electromyography system for synchronized analysis, making an innovative contribution to the biomechanical research of fencing techniques. This technological combination allows for more precise tracking of an athlete’s three-dimensional movement trajectories and muscle activation, and offers new perspectives and more accurate guidance for training. The results are as follows. (1) During the forward lunge step, the integrated electromyographic activity of the deltoid muscle significantly increases (152.55 µV·s, p = 0.045), indicating a higher demand for arm stability in this movement. There are no significant differences in the activation levels of the biceps brachii and triceps brachii. The activation of the forearm muscles, specifically the extensor carpi radialis longus and extensor carpi radialis brevis, is significantly enhanced, at 81.61 µV·s (p = 0.047) and 98.72 µV·s (p = 0.049), respectively. For the lower limbs, the activation of the tibialis anterior muscle significantly increases (110.34 µV·s, p = 0.000). The activation of the gastrocnemius medialis and gastrocnemius lateralis also significantly enhances, with values of 53.22 µV·s (p = 0.001) and 35.75 µV·s (p = 0.000), respectively. The contribution of the deltoid muscle significantly increases to 31.2%, while the tibialis anterior muscle contribution increases to 26.5%. (2) The work also compares muscle activity, movement characteristics, and biomechanical parameters across athletes of different skill levels (beginner, intermediate, and advanced). The results show that the beginner group has the highest electromyography activity intensity (45.2 ± 5.1 µV), while the advanced group has the lowest (32.5 ± 3.8 µV). The movement trajectory stability is 12.3 ± 2.1 mm/s for the beginner group and 6.5 ± 1.2 mm/s for the advanced group. These results suggest that advanced athletes exhibit higher training effects in muscle activation efficiency and energy economy. These findings provide important theoretical support for optimizing fencing training methods and improving athletic performance.

Research on the integration of biomechanical expression of microscopic biological forms and modern painting techniques

Fengmin Wang — 2025-02-14

This study explores the integration of artistic expression of microbial forms with modern painting techniques, focusing on the application of digital art tools in the reproduction of microscopic structures. Through the use of computer-aided design, 3D modeling, and virtual reality technology, we accurately present the details, dynamics, and textures of microscopic organisms. Incorporating insights from biomechanics, the study explores how the physical characteristics and movement patterns of microorganisms can inform and enhance artistic representation. Biomechanics, the study of the mechanical aspects of living organisms, provides a unique lens through which artists can understand the fluidity and complexity of microbial life. By observing the locomotion and interaction of these organisms within their environments, artists can create more dynamic and realistic portrayals that capture the essence of microbial behavior. Drawing on knowledge of how microbes move, interact, and adapt in their minuscule habitats, as gleaned from biomechanics, we are able to animate our digital models in a more biologically plausible manner. For example, mimicking the undulating motion of cilia or the elastic deformation of cell membranes under stress imparts a new level of authenticity to our artistic reconstructions. Experimental results show that an increase in drawing resolution significantly enhances the fidelity of details and artistic effects. When texture details reach 100 ppi, the artwork’s expressiveness scores 9 points. Additionally, as the style fusion coefficient increases to 0.7, both the accuracy of the artistic style and the visual impact are notably improved. These findings suggest that the application of digital tools not only provides innovative expressive possibilities for the artistic creation of microbial forms but also allows for the exploration of their biomechanical characteristics, such as elasticity, motility, and response to external forces. By incorporating biomechanical principles into the artistic representation of microorganisms, this research opens new avenues for understanding how these organisms function and interact within their ecosystems. The fusion of art and biomechanics can lead to a deeper appreciation of the complexity of life at the microscopic level and inspire future studies in both scientific and artistic domains.

Dynamic identification model of psychological state in Ideological and Political Education based on biosensing

Lina Wang — 2025-02-14

Individuals’ psychological states greatly influence how they participate and react to educational processes, especially when it comes to ideological and political education. Ideological and political education (IPE) is an essential component of educational systems that aims to develop a sense of national identity, social duty, and confidence in students. This research explores the application of biosensor technologies to analyze students’ psychological states within the context of ideological and political education. Students’ lifestyles and stress levels often lead to psychological issues, but conventional IPE techniques lack real-time, individualized data for effective mental health treatment. This research introduces a model, Efficient Osprey Optimized Dynamic Long Short-Term Memory (EOO-DLSTM), to identify the psychological state for Ideological and Political Education utilizing biosensing technologies to assess students’ stress and emotional states in real-time. The model uses biosensors to collect real-time physiological data that reflects the psychological state of students. The data was preprocessed using a Gaussian filter to remove noise from biosensor data. Power spectral density (PSD) is used to extract the features from preprocessed data. EOO is used to optimize and select the feature from the biosensor, and DLSTM can be employed to identify the psychological state. Based on experimental findings, the model can accurately identify the psychological states of students, including information about their stress levels and emotional involvement. The proposed EOO-DLSTM outperforms the existing systems such as Accuracy (95.32%), Precision (93.97%), Recall (96.18%), and F1 score (97.62%). The EOO-DLSTM model surpasses traditional models through the utilization of advanced optimization techniques for enhanced accuracy in recognizing psychological states from biosensor data. It is effective in handling overlapping features and complex temporal dependencies, thus being very suitable for real-time monitoring of mental health. The approach emphasizes how biosensing technologies can be used in educational frameworks to support students’ overall development.

This study explores the biomechanical mechanisms and long-term effects of sports intervention on improving the intrinsic capacity of elderly people. Through experiments and model simulations, the effects of sports intervention on muscle strength, gait stability, joint mobility, fall risk, physical function, and mental health of elderly people are evaluated. The experimental results showed that the experimental group showed significant improvement in various indicators after intervention, especially in muscle strength (38.4 ± 5.2 Nm increased to 45.6 ± 4.8 Nm, p < 0.05), gait stability (decreased from 45.3 mm to 35.1 mm, p < 0.05), joint range of motion (increased from 102.1 ± 8.3° to 114.3 ± 7.5°, p < 0.05), and fall risk (decreased from 27.3% to 12.3%, p < 0.05). In contrast, the control group did not show significant changes. The SF-36 physical function score also significantly improved (from 47.2 ± 6.3 points to 63.5 ± 5.6 points, p < 0.05), and the mental health score increased from 56.4 ± 7.1 points to 70.1 ± 6.3 points (p < 0.05). The simulation analysis results are highly consistent with the experimental data, and the model simulation has small errors in predicting muscle strength, gait stability, and other aspects compared to the actual experimental data, further verifying the effectiveness of the exercise intervention. In summary, this study indicates that sports intervention can effectively improve the physical function and mental health of elderly people by improving biomechanical indicators such as muscle strength, gait stability, and joint mobility, thereby reducing the risk of falls and enhancing their quality of life. The high consistency between model simulation and experimental data provides scientific basis and technical support for future health interventions for the elderly.

Mesenchymal stem cells applications in spinal cord injury

Wanli He — 2025-02-14

Spinal cord injury (SCI) is a severe functional impairment of the limbs caused by direct or indirect external factors. The consequences of SCI can be extensive, encompassing the partial loss of sensation, movement, and sphincter function. This is attributable to the loss of neurons, an inflammatory response, and immune cell infiltration. SCI can result in long-term physical and psychological harm to patients, as well as imposing a significant economic burden on the entire society. Mesenchymal stem cells (MSCs) are a type of pluripotent stem cell that exhibits both self-renewal and multipotent differentiation abilities. They possess the anti-inflammatory properties, immunoregulatory abilities, and the capacity for neural and vascular regeneration ability, collectively rendering them a promising candidate for the treatment of SCI. In this review, we provide a comprehensive overview of the preclinical and clinical applications of MSCs in SCI and the underlying mechanisms, discuss the limitations of MSC application in SCI and the possible solutions, hope to provide some useful insights for the scientists.

Biosensing measurement and psychological mechanism exploration of emotional responses in English learners

Caiping Li — 2025-02-14

Emotions have an important role in English language learners (ELL), impacting motivation, engagement, and performance. Understanding how emotions influence ELL performance is critical for creating effective instructional programs. Previous research has explored emotional reactions utilizing self-reports or behavioral observations, but only a small amount of research has used biosensing technology to offer objective, real-time data on emotional states. The purpose of this research is to examine English learners’ emotional responses using biosensing measurements to investigate the psychological mechanisms supporting these responses and offer knowledge about how emotions influence language learning. The investigation involved 150 English language learners. Biosensing devices were used to evaluate physiological indicators such as heart rate variability, skin conductivity, and facial expressions while students completed English language tasks. Furthermore, psychological mechanisms were investigated using questionnaires and interviews, yielding qualitative insights into how learners experience and handle their emotions during the learning process. Statistical analysis, such as regression, descriptive, correlation analysis, ANOVA, and chi-square statistics, was used to investigate the association between emotional responses and language learning efficacy. The findings show a strong association between good emotional reactions and better language learning outcomes, whereas negative emotions, such as anxiety, are associated with lower engagement and performance. Finally, this approach emphasizes the relevance of understanding emotional dynamics in language learning and the necessity of developing methods to enhance positive emotional involvement.

Biophysical and mechanistic insights of declining birth rates on preschool education resource allocation in China: A data-driven perspective

Shibin Ye — 2025-02-14

The continuous decline in China's birth rate has profound implications that intersect with biophysical and mechanistic aspects relevant to biomechanics. This article commences by scrutinizing the alterations in China's birth rate over the past decade. The diminishing birth rate, underpinned by biological factors, has a direct bearing on the quantity of children enrolling in kindergartens. This, in turn, instigates modifications in the requisition for preschool education institutions and educators. From a biomechanical vantage point, the reduction in the number of children alters the physical and mechanical environment within preschool settings. For instance, the collective body mass and force distributions during play and physical activities change. With fewer children, the forces exerted on play equipment and the floor surfaces vary, potentially affecting the wear and tear patterns and the biomechanical feedback that the environment provides to the children. The diversity in body sizes and physical capabilities among a smaller cohort of children also demands a reconsideration of the biomechanical suitability of furniture and teaching aids. Based on the biological metamorphoses in the birth population, data analysis prognoses an impending oversupply of preschool education resources in China in the forthcoming years, especially in the eastern region. Conversely, the central and western regions, along with the urban-rural divide, are anticipated to face a dearth of resources. These disparities not only pertain to the quantity but also to the biomechanical adequacy of the resources. Different regions may have children with varying genetic predispositions and environmental exposures that influence their biomechanical development, thereby necessitating region-specific resource optimization. The biological shifts in birth rates thus levy more exacting requisites on education policies, resource optimization, and the equilibration of regional education. To surmount this obstacle, this article proffers bespoke policy recommendations factoring in biophysical and biomechanical considerations. This includes calibrating resource allocation to harmonize with the biomechanical idiosyncrasies of children in diverse regions, augmenting the biomechanical relevance and quality of education in rural areas, and fortifying policy guidance to actualize the judicious utilization and sustainable progression of education resources that are conducive to the healthy biomechanical development of children.

Xueqin Wang — 2025-02-14

Standardized English language and efficient translation techniques are required to guarantee global usability and cultural relevance because of the growing dependence on biosensors in communication technologies. In particular, the research aims to understand the role of biosensors, particularly wearable sensors, in enabling communication in other cultures, like using a sign language (SL) translator system. The information would be recorded through motion sensors designed to determine hand movements and gestures based on any recorded movement. Raw data would need bandpass filtering of both extraneous artifacts and the surrounding noise. Visual Geometry Group 16 (VGG16) is applied for feature extraction from biosensor data. A novel Adjustable Moth Flame-Tuned Efficient Recurrent Neural Network (AMF-ERNN) transformer model that is used to achieve translations from sensor signals to text sentences is introduced. AMF is used to select and optimize the features of an ERNN model to enhance its efficiency and performance while translating sensor signals to text. Results show that the suggested model outperformed traditional algorithms by achieving accuracy (98.5%), recall (98.3%), precision (98.2%), F1-score (98.4%), and WER (35.5%). These results demonstrate the way biosensors can promote accurate and culturally aware translations. The study concludes by emphasizing the importance of English terminology standardization to enhance the accessibility and effectiveness of biosensor-based translation systems across diverse cultural contexts.

Equipment-assisted training to improve the explosiveness and agility of football players

Fangfang Wen — 2025-02-17

Main: Football players need to release power in a short time when they dribble or shoot quickly, so they need explosive power. Explosive power comes from muscle strength, and muscle strength comes from muscle mass. Result: Football players can increase leg muscle mass to increase the upper limit of muscle strength, the upper limit of explosive power, and the upper limit of jumping ability. Discussion: Agility ladder training (rope ladder) is mainly used to practice coordination, balance and agility. It can enhance the speed of lateral displacement, and also enable the feet to move faster and increase the frequency of steps. Football players need to do this training. During training, the toes should be stepped on the right rhythm, and the hips can be swung while stepping, allowing the body to twist to any angle. Combined with cross steps and single-foot in and out, it can greatly increase the flexibility of both offense and defense. Rope ladder training. It provides a great multi-plane dynamic warm-up, which can develop the connection between the brain and muscles, and is also good for eccentric contraction and stability. In addition, it can also enhance the reaction time to the ball and exercise the muscles of the feet. Methods: Short-distance sprinting can increase the activity of fast-twitch muscle fibers, which contribute most to explosive power. At the same time, dynamic weight training such as squats and box jumps can significantly increase the strength of lower limb muscles for football players. The increase in weight and number of repetitions in strength training should be gradual according to individual ability to avoid muscle damage. Focusing on strengthening the stability of the core muscles can effectively support the development of explosive power in the leg muscles. Conclusion: Football explosive power training can train the ability of muscle cycle lengthening and shortening, effectively utilize the elastic potential energy stored in the soft tissue during the lengthening process, reduce the energy consumption of direct muscle contraction, and improve explosive power energy.

Yuhong Cui — 2025-02-18

To enhance the effectiveness of physical education and improve students’ learning experiences, this work explores the design of a physical education teaching platform system based on Virtual Reality (VR) technology. First, a VR-supported physical education system is constructed and project-based learning and Science, Technology, Engineering, Arts, and Mathematics (STEAM) educational concepts are innovatively integrated into the design of the system’s objectives and teaching content. The system’s functionality and performance are tested across various VR devices. The results indicate that the devices consistently and effectively support the operation of the VR system, providing reliable technical support for physical education activities. Additionally, taking tennis teaching as an example, a comparative experiment was conducted on college students in the experimental group and the control group to assess the impact of the VR system on students' tennis skills and learning attitudes and to explore how VR affects biomechanical performance in physical activities such as tennis. The visual cues of the ball's trajectory and speed can influence a player's anticipatory muscle activation and movement initiation. Through repeated exposure to different ball flight patterns in VR, players can develop more accurate muscle recruitment strategies. The kinematic chain of movements in tennis, from the feet to the torso, arm, and racquet, can be analyzed and optimized with the help of VR. It allows players to visualize and correct any inefficiencies or incorrect biomechanical sequencing. The results show that after the intervention, the experimental group achieves an average score of 91.8 in tennis skills, compared to 83.8 in the control group, with a p-value of < 0.001. In terms of overall learning attitude, the experimental group has a mean score of 4.04, while the control group scores 3.22, with a p-value < 0.001. These findings demonstrate that, compared to traditional teaching methods, VR-based teaching more effectively improves students’ tennis skills and learning attitudes. The results of this work provide theoretical support and practical guidance for the application of VR technology in physical education, contributing to the improvement of teaching quality and effectiveness.

Biomechanical effects of different intensity combinations of aerobic exercise on the enhancement of physiological fitness of college students

Congsheng Ji — 2025-02-18

Aerobic exercise is an effective way to improve cardiorespiratory function and enhance physical fitness, which has a positive impact on the physiological health level of college students, and this study aims to investigate the impact of aerobic exercise with different combinations of intensity on the enhancement of physiological health level of college students. Twenty college students, aged 18–24, in robust health and devoid of long-term exercise backgrounds, were recruited. They engaged in three 30-minute aerobic exercise regimens: low-to-moderate, low-to-high, and moderate-to-high intensity. Biomechanically, each intensity level triggered distinct muscular activation patterns and energy demands. The physiological health indexes of the subjects were measured before and after the exercise, including the heart rate, the degree of self-consciousness of fatigue, the oxygen saturation, the perfusion index, and the emotional state. All indicators can be measured by professional equipment, and different intensity groups are determined according to the intensity of aerobic respiration. The results of the study showed that before the exercise intervention, there was no difference between the physiological health indicators of all subjects, which was homogeneous. In contrast, after the exercise intervention, physiological health indicators showed changes due to different intensities of aerobic exercise. In the two indicators of heart rate and conscious fatigue, there was a significant difference in the enhancement of the two indicators by aerobic exercise (P < 0.05), and the greater the intensity of aerobic exercise, the greater the effect on heart rate and conscious fatigue. Higher intensity aerobic exercise spurred the heart to work harder, pumping blood more vigorously to fuel active muscles, as dictated by biomechanical principles. In the two indicators of oxygen saturation and perfusion index, the effect of aerobic exercise did not have a significant difference (P > 0.05), and did not show a specific pattern of change. In terms of emotional state indexes, the effects of aerobic exercise of different intensities on the subjects were reflected in different emotional indexes, but in terms of the overall emotional disturbance index, aerobic exercise of different intensities did not have a significant effect on the emotional disturbance index. In sum, aerobic exercise’s biomechanical benefits for students’ health are clear. Colleges should boost its promotion, offer varied programs, and guide participation to harness these advantages for enhanced physical and mental health.

With a student satisfaction rate of 95.6%, the experimental results confirm the efficiency of the evaluation model developed in this article. The study’s results show that the suggested model (PE-DMOA) is 98.5% accurate. This means that it helps to look into the effects of machine learning and biomechanics on physical education teaching and gives good recall, accuracy, and precision results. Educators and learners can utilize the PE-DMOA evaluation model to enhance the quality and efficiency of instruction, streamline administrative tasks, and advance the scientific, standardized, and specialized delivery of physical education in classrooms.

Comprehensive assessment of lower limb coordination during the heel strike phase in Parkinson’s disease

Roberta Minino — 2025-02-18

Parkinson’s disease (PD) is character rised by numerous motor symptoms, including impaired coordination of the lower limbs, which reduces stability. The heel strike phase is crucial in gait, as it follows the single step phase and precedes the transfer of weight between limbs, requiring precise control to maintain balance. Impaired coordination during this phase can therefore compromise gait and stability. Therefore, this study aimed to investigate physiological coordination patterns of the lower limbs during the heel strike phase and identify potential alterations in patients with PD. Twenty-three patients with PD and 23 healthy controls participated in this study. Gait of each participant was recorded with a stereophotogrammetric system with 55 reflective markers and data were trimmed to ±15 milliseconds and analysed to assess joint coordination of ankles, knees and hips. Lower limb joint coordination was assessed through pairwise correlations of their acceleration time series. The results showed that PD patients exhibited reduced coordination during the left heel strike, involving all three joints of the left lower limb and ankle and hip of the right lower limb. However, increased coordination between knees was observed, possibly indicating compensatory mechanisms. Furthermore, the difference in coordination between each PD patient and the average coordination of the healthy control group significantly correlated with both disease duration and UPDRS-III scores, highlighting the association between coordination impairments, PD severity, and disease progression. In conclusion, individuals with PD show significant alterations in lower limb coordination during the heel strike phase. These alterations are associated with disease severity and progression, emphasising the need for targeted interventions to address gait dysfunction in PD.

CALF-GAN: Multi-scale convolutional attention for latent feature-guided cross-modality MR image synthesis

Xinmiao Zhu — 2025-02-18

Multimodal medical image synthesis plays a crucial supportive role in research within the field of biomechanics, providing high-precision data and analytical methods for studies on anatomical structures, tissue characteristics, and mechanical modeling. However, due to practical constraints, certain modalities of medical images may be difficult to obtain, posing challenges for model training and high-accuracy biomechanical research. Existing methods employ convolutional neural network (CNN)-based generative adversarial models to synthesize missing modality information across modalities. However, CNNs are limited in their ability to model long-range dependencies. Transformers offer a new paradigm to address these limitations, yet their high computational and memory demands remain a significant drawback. To tackle these challenges, we propose a novel generative adversarial model, termed the Convolutional Attention Latent Feature GAN (CALF-GAN), which leverages multi-scale convolutional attention for cross-modal medical image synthesis. A dedicated latent attribute separation module is employed to disentangle modality-specific features between source and target modality images, enhancing the synthesis of medical semantics, such as pixel intensity values. Furthermore, to improve the model’s capacity for long-range dependency modeling while reducing computational overhead, we design a generation module based on multi-scale convolutional attention, capturing long-range dependencies using only convolutional operations. Extensive experiments conducted on various medical image datasets demonstrate that CALF-GAN achieves remarkable generalizability and outstanding overall performance under low memory requirements, making it well-suited for application in high-precision biomechanics research.

Wei Luo — 2025-02-18

With the rapid advancement of biomechanical research and educational big data, there is a growing need to integrate sophisticated analytical tools to enhance the understanding of human movement, learning behaviors, and their interactions. Traditional machine learning models often fall short in capturing the complex, multi-dimensional relationships inherent in biomechanical and educational datasets, leading to limited precision, inadequate personalization, and poor generalization capabilities, which restrict their applicability in dynamic teaching environments. To address these challenges, this paper proposes a machine learning model based on Factor Space Mathematical Theory integrated with the extreme gradient boosting (XGBoost) algorithm. By leveraging Factor Space Mathematical Theory, the model effectively captures the multi-dimensional characteristics of biomechanical and educational data, addressing the oversimplification and unidimensional nature of traditional models. Moreover, with the robust classification and prediction performance of XGBoost, the proposed model enhances the ability to generalize and process complex educational data. Experimental results demonstrate that the proposed model achieves an accuracy of 0.92 and an F1 score of 0.90 in predicting students’ biomechanical performance metrics, such as gait analysis and posture stability, which are critical for understanding learning behaviors in physical education and vocational training. The model outperforms the standalone XGBoost model by a significant margin of 0.05 in accuracy. Additionally, MSE analysis across diverse datasets reveals no evidence of overfitting, further validating the model’s strong generalization capabilities. This study highlights the effectiveness of combining Factor Space Theory with XGBoost, offering improved accuracy, operational efficiency, and adaptability in biomechanical data analysis and educational behavior prediction. The findings provide a novel perspective and practical approach to advancing biomechanical research and its application in educational reform, particularly in higher vocational education.

Research on the antistatic performance of peanut shells @ glucose biochar/epoxy composites

Mengxiao Guo — 2025-02-18

In this work, the glucose nanocarbon spheres (GC) were in situ decorated on the surface of lamellar peanut shell biochar (PSAC) to construct the self-modified conductive function unit of biomass (PSAC@GC). The effects of PSAC@GC at different carbonization temperatures on the conductivity, the antistatic properties, and the thermal stability of epoxy composites were investigated. This unique structure not only improves the dispersion of GC nanospheres in the epoxy resin, but the larger carbon framework of PSAC also contributed to forming a continuous conductive network. Moreover, the well-dispersed GC nanospheres on PSAC facilitate the transfer of surface free electrons, effectively improving the electrical conductivity and ultimately strengthening the antistatic properties of the composites. The results show that when the carbonization temperature was 900 ℃, the conductivity of PSAC@GC with a mass ratio of 1:1 was 41.19 S/m, which represents an increase of 135% and 43% compared to PSAC and GC, respectively. When 5 wt.% PSAC@GC was added, it showed good dispersion in the epoxy resin, and the surface resistivity of the composites was reduced to 1.89 × 108 Ω. The work provides a new approach for the development of environmentally friendly and cost-effective novel antistatic carbon material.

The interplay of biomechanical movement patterns and aesthetic context on explicit and implicit altruistic behavior in pupils

Tingting Wang — 2025-02-18

The current study delved into how aesthetic context intertwined with cell molecular biomechanics to influence pupils’ explicit and implicit altruistic behaviour. In Experiment 1, when looking at the effects of different aesthetic contexts on pupils’ explicit altruistic behaviour, it was found that explicit aesthetic context had a notable priming effect on implicit altruistic behaviour. From a cell molecular biomechanics perspective, perhaps in an explicit aesthetic context, specific cell surface receptors respond to external stimuli related to beauty, triggering intracellular molecular signaling pathways that eventually influence implicit altruistic responses more than in implicit or non-aesthetic contexts where such coordinated signaling is less pronounced. Experiment 2 on implicit altruistic behaviour again detected the implicit association test (IAT) effect. Implicit aesthetic contexts showed a significant priming effect. Here, at the cell molecular level, the microenvironment within cells might be altered by the implicit aesthetic perception, like changes in cytoplasmic viscosity or the movement of organelles affected by aesthetic feelings, which then play a key role in shaping implicit altruistic behaviour compared to explicit and non-aesthetic contexts. Overall, it’s clear that explicit and implicit altruistic behaviours rely on distinct processing mechanisms involving both aesthetic context and cell molecular biomechanics. The two aesthetic contexts have selective impacts via different path mechanisms related to these cellular processes.

Cailing Liao — 2025-02-19

Background: Metabolomics can offer vital information into a cancer’s condition. Despite its potential, research on the metabolites linked to colorectal cancer (CRC) remains limited. From a cell molecular biomechanics perspective, understanding these metabolite associations can offer a deeper understanding of the disease’s underlying mechanisms. We performed Mendelian randomisation (MR) analyses to investigate causal associations between 486 blood metabolites and CRC. Methods: Data on blood metabolites were derived from a Genome-wide association study (GWAS) involving 7824 Europeans. Additionally, summary statistics for CRC were sourced from the FinnGen consortium database. To explore the causal relationship between CRC and blood metabolites, we primarily utilized the inverse variance weighted (IVW) analysis. Supplementary analyses incorporated MR-Egger and weighted median methods to ensure the robustness of our findings. The potential for pleiotropic effects was evaluated using the Cochran’s Q test and the MR-Egger intercept test. Furthermore, colocalization analyses were performed to ascertain whether the observed associations were influenced by specific genetic loci within the genomic region. Results: The results of this study indicated significant associations between eight metabolites: Indolelactate (OR = 2.62, 95% confidence interval (CI): 0.26–1.66, p = 0.007), 1-heptadecanoylglycerophosphocholine (OR = 1.37, 95% CI: 0.10–0.54, p = 0.005), 1-stearoylglycerophosphocholine (OR = 3.47, 95% CI: 0.65–1.84, p = 0.00005) , X-11792 (OR = 0.57, 95% CI: −0.94–−0.17, p = 0.005), X-12038 (OR = 0.44, 95% CI: −1.50–−0. 12, p = 0.021), X-12212 (OR = 1.96, 95% CI: 0.10–1.25, p = 0. 022), X-14056 (OR = 0.50, 95% CI: −1.28–−0.12, p = 0.018) , X-14745 (OR 0.41, 95% CI: −1.48–−0.31, p = 0.003) and CRC. These metabolites might play roles in altering the mechanical properties of cells in the colon. They could potentially affect the cytoskeletal structure, cell membrane fluidity, or the way cells interact with the extracellular matrix. Conclusion: The eight identified blood metabolites with causative influence on CRC provide valuable clues for understanding CRC from a cell molecular biomechanics angle, which can further aid in its screening, prevention, and treatment strategies.

Francesca Latino — 2025-02-19

The engagement of athletes in competitive Padel is becoming progressively prevalent, and this heightened participation elicits apprehensions regarding the prevalence of overtraining and sports-related injuries. In this framework, the objective of the present investigation was to examine the potential role of Heart Rate Variability (HRV) monitoring in identifying overtraining injuries among female professional Padel athletes. A cohort of 66 elite female Padel players, with ages ranging from 17 to 32 years, was recruited for the study. The duration of the investigation extended over a 13-week period, during which the participants were observed concerning HRV indices and musculoskeletal injuries while adhering to their customary Padel training protocols. The assessment of HRV indices was executed to ascertain the autonomic nervous system’s response to a state of overload injury, while the Oslo Sports Trauma Research Center (OSTRC) Overuse Injury Questionnaire was administered to assess the prevalence of musculoskeletal overuse injuries, both at baseline and upon completion of the observational period. Utilizing a Paired Samples t-test analysis, the results indicated a statistically significant difference between pre- and post-test assessments, which illustrated that the observational cohort experienced a notable decline in HRV concomitant with an escalation in the incidence of musculoskeletal overuse injuries. Consequently, the findings imply that the monitoring of HRV responses may facilitate the early detection of overuse injuries, inform rehabilitation strategies, and advance return-to-sport protocols, thereby safeguarding and promoting the recovery of injured tissues.

Zanthoxylum bungeanum-derived extracellular vesicles alleviate liver fibrosis via TGF-β1/Smad pathway

Tao Jiang — 2025-02-19

The activation of hepatic stellate cells (aHSCs) play a role for the occurrence and progression of liver fibrosis. However, effective drugs that can prevent or reverse this pathological process remain unavailable. Zanthoxylum bungeanum Maxim. (Rutaceae) is an edible and medicinal plant with diverse bioactivities, including antiparasitic, antimicrobial, and anti-inflammatory effects. This study investigates the therapeutic potential and underlying mechanisms of Zanthoxylum bungeanum-derived extracellular vesicles (ZEVs) in liver fibrosis, using the human HSCs LX-2 cells and alcohol-induced mice model of liver fibrosis. The results show that ZEVs significantly inhibit the proliferation and migration of LX-2 cells, while downregulating the fibrosis-related proteins and genes expression. Furthermore, oral administration of ZEVs significantly decreased serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in mice with liver fibrosis, reducing liver inflammation, collagen deposition, and lipid droplet accumulation. Additionally, miR-9 and miR-17 in ZEVs were found to significantly reduce the synthesis of fibrosis-related proteins in activated LX-2 cells. Mechanistic studies further revealed that ZEVs suppressed the gene levels of TGF-β1, Smad2 and Smad3 in activated LX-2 cells. In conclusion, ZEVs are a possible treatment option for liver fibrosis, potentially through modulation of the TGF-β1/Smad signaling pathway.

Lili Qin — 2025-02-19

To increase the use of wearable biosensors in language learning environments, approaches for accurately extracting small signs of cognitive load are necessary. However, assessing subjective cognitive states, such as the load experienced during language acquisition, provides significant obstacles. This research uses data from physiological sensors worn on the wrist, such as skin conductance, skin temperature, heart rate, and R-R intervals, to organize a machine learning (ML) challenge to develop techniques for quantifying cognitive load in English learners. Participants used data from respondents who completed English language tasks of various difficulty levels. A robust evaluation of preprocessing approaches such as Z-score normalization, signal detrending, and moving average filtering, as well as feature extraction methods such as time-domain and frequency-domain analysis, demonstrated that robust models efficiently used biosensor data. Classical classifiers, such as Adaptive Random Forest (ARF), performed better when optimized with Barnacle Mating Optimization (BMO) for hyperparameter tuning. The proposed method of BMO-ARF has attained accuracy at 95.89%, F1-score in the cognitive load of low at 0.95, medium at 0.90 and high at 0.97, sensitivity in the cognitive load of low at 80.3%, medium at 88.5% and high at 93.0% and specificity in the cognitive load of low at 87.5%, medium at 91.8% and high at 95.1%. The results show that cognitive load classifications were more accurate for higher-difficulty tasks and particular learners, potentially impacted by model overfitting and the subjective nature of physiological responses. The research highlights the need for more sophisticated annotation techniques to improve cognitive load monitoring in language learning environments and handle student response variability.

This observational study investigates the stress distribution in knee joint structures, specifically focusing on the meniscus and primary ligaments of the supporting leg during the support phase of a maximal-effort soccer instep kick executed by an elite-level player. Understanding these stress patterns is crucial for injury prevention and enhancing performance in high-impact soccer actions. A three-dimensional (3D) knee model was developed utilizing CT and MRI data. Finite element (FE) analysis was conducted to evaluate stress distribution patterns across the lateral and medial menisci, medial collateral ligament (MCL), and anterior cruciate ligament (ACL). The analysis revealed peak von Mises stresses of 16.127 MPa in the lateral meniscus, 10.845 MPa in the medial meniscus, 36.613 MPa in the MCL, and 22.863 MPa in the ACL. These findings indicate significant stress concentrations in the lateral meniscus, proximal MCL, and femoral insertion of the ACL. The identified stress distribution patterns specifically related to the knee joint during the instep kicking phase provide critical insights into the internal mechanical demands placed on the joint structures. This study enhances the understanding of stress concentrations in the meniscus and ligaments during soccer kicks, emphasizing the potential for targeted analysis of these stress patterns to inform injury prevention strategies. It suggests that a deeper comprehension of the stress distribution mechanics could contribute to more effective training protocols and rehabilitation approaches for athletes, ultimately improving performance and reducing the likelihood of knee injuries during soccer activities.

Causal relationship between Alzheimer’s disease and obstructive sleep apnoea: Insights from a biomechanics-oriented bidirectional mendelian randomization study

Liumei Yuan — 2025-02-20

Background: The latest observational studies revealed a possible association between Alzheimer ‘s disease (AD) and obstructive sleep apnoea (OSA). In AD, the accumulation of amyloid-beta plaques and tau tangles disrupts the normal structure and function of neurons in the brain. These pathological changes can affect the mechanical properties of neural tissues, altering their elasticity and stiffness. Such alterations might extend to the neural circuits responsible for regulating sleep and respiration, potentially influencing the occurrence of OSA. We used bidirectional Mendelian randomization approach to analyze causalities between OSA, its typical symptoms (snoring and daytime sleepiness) and AD in European populations. Methods: Single nucleotide polymorphisms of AD and OSA, snoring, daytime dozing were selected as instrumental variables. Preliminary MR analysis was inverse-variance weighted (IVW) method. The Cochran Q test, MR-Egger analysis, ‘leave-one-out’ test were used to verify the data robustness. Results were adjusted for Bonferroni correction thresholds. Results: Results from IVW demonstrated a suggestive correlation between AD and higher risks of sleep apnoea (OR 1.0008, 95%CI 1.0000–1.0016, p = 0.044) after Bonferroni correction. However, reverse MR analysis showed no association of genetically primed sleep apnoea towards AD (p = 0.294). No causal effect was detected between genetic AD and snoring, daytime dozing. From a biomechanical perspective, the positive correlation between AD and increased risk of sleep apnoea could be due to the fact that the structural changes in the brain caused by AD might lead to changes in the biomechanical forces exerted on the brainstem regions that control breathing during sleep. Conclusions: The findings of the MR study support that AD might increase the risk of OSA. Therefore, individuals with AD should strengthen sleep monitoring, sleep hygiene and develop a regular sleep-wake pattern. Understanding these underlying biomechanical mechanisms could provide valuable insights for developing targeted interventions to mitigate the risk of OSA in AD patients and potentially improve their overall sleep quality and disease management.

Wenjun Bi — 2025-02-21

Sports injuries can significantly impact athletes’ performance and career longevity, making their early prediction and prevention a critical area of research. Traditional methods often fall short of capturing the complex, nonlinear interactions between various risk factors that contribute to injuries. The early prediction of sports injuries is vital for the well-being and performance optimization of athletes. This paper introduces Intrinsic Permutation Entropy Deep Learning (IPE-DL), a novel framework that synergizes permutation entropy with deep learning architectures to enhance the prediction of sports injuries. The IPE-DL method leverages the concept of permutation entropy to quantify the complexity and regularity of time-series data derived from athletes’ physiological and biomechanical signals. These entropy measures serve as critical features, capturing the inherent nonlinear dynamics within the data. The experiments demonstrate that the IPE-DL model outperforms traditional machine learning approaches and state-of-the-art deep learning models in predicting sports injuries. The proposed deep learning model is trained on a comprehensive dataset encompassing various risk factors, including athlete-specific metrics, training load parameters, and environmental conditions. Our dataset includes data from over 1,000 athletes, with a total of 100,000 training sessions recorded. The experiments demonstrate that the IPE-DL model outperforms traditional machine learning approaches and state-of-the-art deep learning models, achieving an accuracy of 92%, a sensitivity of 89%, and a specificity of 94% in predicting sports injuries. The results highlight the model’s capability to provide early warnings by identifying subtle changes in athletes’ physiological and biomechanical states that precede injuries.

The influencing factors of consumer purchase intention in e-commerce live marketing under the background of green consumption view: A biomechanics-inspired analysis

Xudong Hu — 2025-02-21

The live-streaming e-commerce industry has thrived with the progress of mobile Internet, becoming an integral part of consumers’ daily lives. Driven by the green consumption and low-carbon living concepts, online consumption has gained popularity, making e-commerce live marketing a significant platform for consumer spending. Resolving how to heighten consumers’ purchase intention and augment sales is a pressing concern for e-commerce live marketing teams and platforms. This research, grounded in grounded theory, dissects the determinants of consumers’ purchase intention in e-commerce live streaming. Four main aspects are identified: people, cargo, market, and consumers’ internal state. Human aspects encompass personal charm and professionalism; cargo elements comprise product features, price incentives, and transaction volume; venue-related factors involve live streaming interaction and comprehensive service; and consumers’ internal state involves a sense of value and trust. Drawing an analogy from biomechanics, the interactions among these factors can be likened to mechanical forces. The influences of people, cargo, and market on consumers’ internal state are analogous to external forces exerted on a biological structure, which then triggers a response in the form of consumers’ internal state change. This internal state, in turn, acts as a driving force for purchase intention, similar to how a biological entity responds and adapts. The mediating role of value and trust is also vital. The findings of this study furnish a solid foundation for enhancing the sophistication and quality of e-commerce live streaming marketing, strengthening consumers’ purchase intention, enriching their purchasing experience, and facilitating the stable and sustainable growth of the e-commerce live streaming sector.

To assess and forecast the mental health conditions of university students utilizing machine learning methodologies, focusing particularly on the influence of the nine psychological symptom dimensions encompassed by the Symptom Checklist-90 (SCL-90). The prevalence of mental health issues among college students is a significant concern. Traditional methods for assessing mental health may lack the precision required for early detection and intervention. Machine learning offers advanced tools to analyze complex data and predict outcomes based on multiple variables. The primary objective is to construct and evaluate predictive models for the mental health status of college students using various machine learning algorithms, optimize their performance, and identify the most impactful psychological symptom dimensions. Psychological health data from 11,943 college students were gathered via an online questionnaire platform. Multiple machine learning algorithms were utilized to develop predictive models. Hyperparameter optimization was achieved through K-fold cross-validation and the northern goshawk optimization algorithm. To tackle class imbalance, the synthetic minority over-sampling technique was employed to create synthetic samples for underrepresented classes. Model performance was assessed using metrics such as accuracy, recall, and f1 score. The light gradient boosting algorithm demonstrated superior performance, with only 6 misclassifications out of 2,388 test samples. Tree-based ensemble methods like random forest and extreme gradient boosting consistently outperformed non-ensemble methods such as k-nearest neighbors, multi-layer perceptron, and kernel discriminant analysis. A detailed analysis using Shapley additive explanations values indicated that features such as obsessive-compulsive symptoms and anxiety were the most influential in the model’s predictions. This study underscores the efficacy and potential of machine learning in mental health assessment. The results provide a robust scientific foundation for the development of early warning systems and targeted intervention strategies to enhance the mental well-being of college students.

Potential biological targets of phytochemicals in regulating inflammatory responses in lung injury

Mengyi Chi — 2025-02-21

Acute lung injury (ALI) is a pulmonary condition caused by various factors, characterized by high mortality rates and significant clinical challenges. The onset of lung injury is closely associated with excessive inflammatory responses, making the modulation of these responses a critical target for ALI therapy. Despite the growing interest in phytochemicals, the mechanisms through which they modulate inflammatory pathways in lung injury remain poorly understood. This knowledge gap underscores the need for further investigation into the biological targets of phytochemicals in regulating lung injury-induced inflammation. The purpose of this study is to identify specific phytochemical compounds that can mitigate inflammation by targeting key signaling pathways, particularly by inhibiting Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-κB); p38 Mitogen-Activated Protein Kinase (p38 MAPK); and c-Jun N-terminal Kinase (JNK) pathways, thereby reducing pro-inflammatory cytokines such as TNF-α, IL-6, and IL-1β. A mouse model of acute lung injury was established, and different concentrations of phytochemicals were administered. Combined with biochemical analyses, immunohistochemical staining, and Western blot experiments, the inhibitory effects of phytochemicals on lung injury and related inflammatory cytokines were evaluated. The results indicate that phytochemicals can significantly suppress the inflammatory response caused by lung injury, reducing the levels of inflammatory cytokines such as TNF-α, IL-6, and IL-1β (p < 0.01). Pathological analyses revealed substantial improvement in lung tissue, particularly in the high-concentration intervention group. Western blot results demonstrated that phytochemicals exert anti-inflammatory effects by inhibiting the activation of NF-κB, p38 MAPK, and JNK signaling pathways. This study provides novel insights into the potential molecular mechanisms underlying the anti-inflammatory effects of phytochemicals in ALI, and identifies specific biological targets for their clinical application, highlighting their promising therapeutic potential.

Exploration and practice of teaching college English writing webcast classes based on B5G and sensing device support under the threshold of intelligent courses: analyzing the physical and physiological impacts on learners

Shali Zhou — 2025-02-21

The post-fifth-generation communication (B5G) and Internet of Things (IoT) environments have not only revolutionized the technological aspects of live English instruction in educational technology but also hold potential implications for the physical and physiological experiences of students during learning. In this research, a mathematical modeling approach based on B5G-IoT is employed to assess the impact on teaching efficacy. Through a set of constructed mathematical formulas, the influence of live broadcasting is statistically examined in a number of areas, including network flexibility, interactive delay, audio and visual clarity, and transmission quality, by building a set of mathematical formulas. The experimental design compares live English teaching effects under 4G, 5G, and B5G network conditions, collecting key indicators such as video clarity, audio signal-to-noise ratio, interactive delay, content delivery completeness, and learning concentration. Results demonstrate that in the B5G environment, video quality achieves 4 K resolution using H.266/VVC codecs, the audio signal-to-noise ratio improves to 30 dB through real-time noise cancellation algorithms, and interaction delay is reduced to less than 30 ms by leveraging ultra-reliable low-latency communication (URLLC) not only foster efficient teacher-student exchanges and a seamless teaching process but also have consequences for students’ physical states. For instance, the improved visual and auditory quality may reduce the strain on students’ eyes and ears, which in turn could affect their overall physical comfort and ability to maintain focus. Additionally, the reduction in interaction delay might lead to more natural and less fatiguing postural adjustments and muscle movements as students interact with the teaching materials. The enhanced reliability and scalability of the B5G network, ensuring 98% knowledge point delivery completeness, can potentially minimize the physical and mental stress associated with disrupted or incomplete learning experiences. This, in turn, may have a positive impact on students’ concentration and active participation in the classroom. By comprehensively considering these aspects, this detailed exploration of B5G and IoT technology applications and implementations offers a more profound understanding of their role in enhancing live English teaching and the associated physical and physiological aspects of student learning.

Energy metabolism during physical exercise: Towards a current conceptualization in physical activity and sport sciences

Jorge L. Petro — 2025-02-19

Energy metabolism is a central topic in physical activity and sports sciences. However, some concepts still require biological contextualization and more precise terminology in scientific literature. In this regard, the purpose of this review was to highlight certain concepts that deserve to be reconsidered and possibly excluded from the vocabulary of exercise and sports sciences. It is argued that the terms “anaerobic” and “aerobic”, used to classify exercises or sports activities, are incorrect and imprecise. Similarly, the persistent use of the term “lactic acid” (i.e., the interchangeable use of lactate and lactic acid, often incorrectly considered the same) consequently leads to the misrepresentation of the phenomenon of “lactic acidosis”, which lacks rigorous biochemical support. Therefore, a conceptual reframing is needed to align with recent findings in exercise biochemistry and molecular biology. The following issues are addressed: i) The estimation of energy system contributions during physical exercise, with emphasis on the most commonly used methods in humans; ii) the classification of energy metabolism—and by extension, exercises—into “anaerobic” and “aerobic”, challenging this dichotomy and proposing a more precise classification into oxygen-independent energy systems (phosphagen and glycolytic) and oxygen-dependent energy systems (mitochondrial oxidative system); iii) the concepts of lactic acid production and lactic acidosis, refuting the idea that lactate accumulation results from oxygen deprivation and highlighting its role as an important metabolic intermediate; and iv) the interaction and contribution of energy systems during physical exertion, stating that energy systems are not activated sequentially but simultaneously, with their predominance depending on metabolic demands. By aligning terminology with contemporary findings in biochemistry and molecular biology, this perspective enhances the understanding and critical analysis of metabolic concepts in sports science education and professional practice, encouraging their adoption based on scientific evidence.
