Artificial intelligence,especially large language models(LLMs),is reshaping how we learn,communicate,and create.These systems provide students and professionals immediate access to fluent,context-aware language that can support learning,increase productivity,and spark creativity.But what happens when their use becomes excessive?This paper explores the potential long-term consequences of over-relying on LLMs-particularly memory,critical thinking,creativity,and motivation.Drawing on research in cognitive psychology,education,neuroscience,and media studies,it argues that LLMs are best understood as cognitive prostheses:incredibly valuable when used wisely,but risky when they replace rather than support human imagination. 展开更多

BACKGROUND Enhancing work engagement among physical education(PE)teachers is crucial for building a strong sports nation and fostering educational advancement.However,PE teachers frequently experience conflicts between work and family roles,significantly impacting their professional involvement.The concept of work-family facilitation,highlighting mutual facilitation between work and family domains,has considerable theoretical and practical significance but remains underexplored in this context.This study integrates ecosystem theory,spillover theory,social exchange theory,and two-factor theory to systematically explore the mechanism through which work-family facilitation influences work engagement.Specifically,it investigates the roles of psychological resilience and job satisfaction in this relationship,providing a novel theoretical perspective and empirical evidence.AIM To systematically explore the mechanism through which work-family facilitation influences work engagement among PE teachers.METHODS A cross-sectional questionnaire survey was conducted among 436 PE teachers.Structural equation modeling was used to examine relationships among variables and assess mediating effects.RESULTS Work-family facilitation positively correlated with psychological resilience,job satisfaction,and work engagement(r=0.323-0.705,P<0.001).Psychological resilience and job satisfaction fully mediated the relationship between work-family facilitation and work engagement,demonstrating a significant chain mediation effect.CONCLUSION This study confirms that promoting work-family facilitation enhances psychological resilience and job satisfaction,thereby significantly boosting work engagement among PE teachers.These findings underline the importance of targeted interventions to enhance work-family resources,psychological resilience,and job satisfaction,contributing to theoretical advancements and practical implications for educational management. 展开更多

Background:The Teaching Personal and Social Responsibility(TPSR)model in physical education(PE)has been shown to promote Social and emotional competence(SEC).However,the underlying mechanisms through which TPSR enhances SEC,particularly in university students within the Chinese context,remain unclear.This study aims to explore the effects of TPSR and the mediating roles of self-efficacy and grit in improving SEC.Methods:71 Chinese university students were in the TPSR group,and 39 in the Traditional Teaching Model(TTM)control group,assessed before and after a 14-week intervention.The Adapted Social and Emotional Competence Scale(ASECS),General Self-Efficacy Scale(GSES),and Short Grit Scale(SGS)were used for measurement.A mixed-design ANOVA assessed TPSR’s effects,with post-hoc t-tests for pre-post differences and mediation analysis for underlying mechanisms.Results:The mixed-design ANOVA revealed a significant interaction between time and intervention on SEC.The TPSR group showed significant improvement from pre-test to post-test(t(70)=−2.63,p=0.011,Cohen’s d=−0.31),whereas the TTM control group did not(t(38)=1.40,p=0.170,Cohen’s d=0.22).The TPSR group also showed a significant increase in self-efficacy(t(70)=−3.67,p<0.001,Cohen’s d=−0.44),while no change was observed in the TTM group(t(38)=0.62,p=0.540,Cohen’s d=0.10).No significant effects were found for grit(F=0.342,p=0.560).Mediation analysis confirmed that self-efficacy significantly mediated the effects of the TPSR intervention on SEC(95%CI:0.0277 to 0.2897).Conclusion:The TPSR intervention led to significant improvements in university students’SEC and self-efficacy,with no significant changes observed in grit.Self-efficacy served as a mediator in the relationship between the intervention and SEC. 展开更多

In the realm of Chinese narrative medicine, narrative thinking holds equal significance to evidence-based thinking within clinical practice, making substantial contributions to patient safety and medical quality. Ancient Chinese medical theories advocate forging a narrative bond with patients, urging healthcare practitioners to utilize Dao Shu Jie He(道术结合 integration of Dao and techniques) and Yi Dao Yu Shu(以道驭术 guiding techniques with Dao) during diagnosis, treatment, and rehabilitation. In this context, Dao(道) in traditional Chinese medicine(TCM) corresponds to narrative thinking(叙事思维) while Shu(术) aligns with scientific thinking(科学思维) in evidence-based medicine. This study adopts “narrative Chinese medicine” within the “discourse system of Chinese narrative medicine” as its framework, centering on medical stories that exemplify the application of narrative thinking in ancient Chinese diagnosis and treatment. It delves into the narrative thinking encapsulated in Chinese medicine, such as Guan Wu Qu Xiang(观物取象 observing things and extracting information), Can He Er Xing(参合而行 final examination and decision by integrating the four diagnoses), Xing Shen Bing Zhi(形神并治 body-spirit treatment), Xin Shen Jian Li(心身兼理 mind-body balance) and Bian Zheng Lun Zhi(辨证论治 treatment based on pattern differentiation). The study endeavors to inspire contemporary medical educators and clinicians to acknowledge the value of narrative thinking in TCM and fully incorporate it into daily medical practice. 展开更多

The role of entropy and enthalpy plays an essential key for the formation of an alloy. This paper illustrates how an alloy is to form and what and why the properties of the alloy are going to have by the entropy and enthalpy effects via a designed enthalpy-entropy plane (EE-plane) based on the Gibbs free energy equation and the introducing a charactering pseudo-unitary lattice (PUL) for entropy alloys. Based on the PUL scheme, the so-called four effects in high entropy alloys are simply nothing but the entropy effect with the other three accompanying effects: the distortion, slow diffusion and cocktail effects. 展开更多

BACKGROUND Physical activity(PA)is a key contributor to the neurocognitive and psychological development of children and adolescents.With the rapid integration of digital technologies in educational and recreational contexts,technology-enhanced PA(TEPA)interventions have emerged as promising tools for promoting mental and cognitive health.However,the effectiveness of various TEPA modalities—such as virtual reality(VR),mobile applications,and biofeedback systems—remains unclear.Prior findings are fragmented across systematic reviews with inconsistent methodologies.This umbrella review was conducted to synthesize current evidence and evaluate whether specific TEPA modalities yield differential benefits.We hypothesized that TEPA interventions with immersive and selfregulatory features provide greater enhancements in executive function(EF),cognitive function(CF),and mental health(MH)than passive or minimally interactive formats.AIM To determine the effects of TEPA interventions and modality-specific characteristics on EF,CF,and MH outcomes in children and adolescents.METHODS An umbrella review of systematic reviews and meta-analyses was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines.Five databases(PubMed,Web of Science,EMBASE,EBSCOhost,and Cochrane Library)were searched up to March 2025.Eligible reviews included participants aged≤18 years,assessed TEPA interventions,and reported EF,CF,or MH outcomes.Methodological quality was assessed using A Measurement Tool to Assess Systematic Reviews 2.Data synthesis was stratified by intervention modality,and heterogeneity was evaluated using the I^(2)statistic.RESULTS A total of 11 systematic reviews and meta-analyses were included.Interventions using VR(2/2),game-based formats(2/2),biofeedback(2/2),and multicomponent programs(1/1)showed consistent evidence of improvements in EF and MH(e.g.,EF:6.92±3.86 vs 3.61±1.67,P<0.001).App-based interventions(3/3)demonstrated mixed or modest effects,while augmented reality-based formats showed limited efficacy.MH outcomes were most frequently improved(9/11 reviews),followed by EF(6/11 reviews)and CF(5/11 reviews).Heterogeneity ranged from moderate to high(I^(2)=42%-78%)across modalities.CONCLUSION TEPA significantly improves MH and selectively enhances executive and CF in youth.Immersive,interactive,and biofeedback-driven modalities are particularly effective. 展开更多

The boundary knot method(BKM)is a simple boundary-type meshless method.Due to the use of non-singular general solutions rather than singular fundamental solutions,BKM does not need to consider the artificial boundary.Therefore,this method has the merits of purely meshless,easy to program,high solution accuracy and so on.In this paper,we investigate the effectiveness of the BKM for solving Helmholtz-type problems under various conditions through a series of novel numerical experiments.The results demonstrate that the BKM is efficient and achieves high computational accuracy for problems with smooth or continuous boundary conditions.However,when applied to discontinuous boundary problems,the method exhibits significant numerical instability,potentially leading to substantial deviations in the computed results.Finally,three potential improvement strategies are proposed to mitigate this limitation. 展开更多

Interpreting is a fast-paced activity where interpreters must make quick choices when faced with uncertainty. This study looks at how professional interpreters handle linguistic uncertainty in English-Chinese sight translation, with a focus on the strategies they use. By analyzing transcription data alongside instructor evaluations, we found that interpreters relied most on creative interpretation and omission, while strategies like paraphrasing, simplification, transformation, addition, and generalization appeared less often. The results show a clear preference for strategies that keep communication flowing without adding unnecessary cognitive load. These findings support the Processing Economy Hypothesis, which suggests interpreters naturally seek efficient ways to process language while maintaining meaning. The study also highlights practical implications for interpreter training, emphasizing the value of flexible, economy-oriented strategies to help interpreters stay fluent under pressure. 展开更多

The paper aims to examine the application of multimedia technology in expanding vocabulary in second language acquisition.Incorporating innovative technology such as mobile applications,gaming applications,websites,and other related online tools has increased learners’vocabulary mastery,engagement,and motivation levels.Interactional processes like media-embedded objects,teach-learning capacity algorithms,and feedback help learners receive the course in a personalized way that considers individual learning patterns or abilities.However,there are the following challenges:accessibility issues,total reliance on technology,and issues related to privacy.The following challenges affecting learning that arise from using gadgets:the digital divide,limited device access,and environmental issues that may distract a learner in a technology-enabled environment.Moreover,the security issue for data and the ethical question of users’information remain important too.Hence,the paper provides arguments that although these technologies contribute significantly to vocabulary acquisition,the challenge that emerges should be addressed by integrating technology in teaching and learning alongside conventional methods for vocabulary acquisition,which is a practical language acquisition tool that should not be monopolized. 展开更多

Most fish exhibit remarkable morphological diversity,which is often influenced by genetic variation and ecological pressures.Consequently,these are the outcomes of organisms’responses to their environment.Meanwhile,modern morphometrics can quantify shape variation within species of the same group.This study aims to determine the body shape variation of Glossogobius giuris from Lake Mainit,Agusan Del Norte,Philippines.60 adult,uniform-sized fish samples were collected and subjected to standardized laboratory procedures.Further,the samples were digitized for 16 homologous landmark points and loaded into Symmetry Asymmetry Geometric Data(SAGE)Software.Across the tested factors—individuals,sides,and individual x sides—result shows that shape variations among individuals were highly significant(F=2.1045,p<0.0001),along with among males(F=3.2711,p<0.0001).Females exhibited higher Fluctuating Asymmetry(FA)(F=18.99,p<0.0001)compared to males(F=7.0964,p<0.0001).It suggests morphological shape differences across the sexes,and the shape variation observed could be a response to environmental perturbations.Shape variations were associated with swimming,food hunting,and predator defense.Moreover,Principal Component Analysis(PCA)demonstrates higher scores of FA in females(81.96%)than in males(74.76%).It was noticed that females had a high fluctuating asymmetry.It might be due to various physiological and ecological pressures compared to males.The observed levels of directional and fluctuating asymmetry in males and females,respectively,may indicate sex-linked morphological and developmental processes,which are important to consider in ecological or evolutionary contexts.Thus,utilizing geometric morphometrics can depict subtle differences across the same populations. 展开更多

Based upon the thiophene-2,5-dicarboxylic acid(H_(2)Tdc),a novel[Sc_(3)(μ_(2)-OH)_(3)(CO_(2))_(4)O_(6)]n inorganic chain-based Sc-MOF with decorated nitrate ions,{[Sc_(3)(OH)_(2)(Tdc)_(3)(NO_(3))]⋅H_(2)O}_(∞)(AEU-1;AEU for Army Engineering University of PLA),was synthesized,which shows good water and chemical stabilities.Significantly,due to channel constriction accompanied by the polar window caused by introducing nitrate ions,AEU-1 exhibits high C_(2)H_(6)/C_(2)H_(4)adsorption selectivity comparable to many famous C_(2)H_(6)-selective MOFs,making it a promising candidate for the purification of methanol-to-olefin(MTO)products.Furthermore,theoretical investigations reveal that the introduced nitrate ions in AEU-1 as the main adsorption sites could provide strong interactions between the framework and C2H6/C3H6 in the full-contacting mode,leading to an increase in the adsorption enthalpies(Qst)of C_(2)H_(6)and C_(3)H_(6),and thus further improving the C_(2)H_(6)/C_(2)H_(4)and C_(3)H_(6)/C_(2)H_(4)adsorption selectivity.Our work could open up a new avenue for constructing MOFs with inorganic polar moieties as adsorption sites for one-step C_(2)H_(4)purification and C3H6 recovery from MTO mixtures with high selectivity. 展开更多

Based on the fundamental equations of piezoelasticity of quasicrystals (QCs), with the symmetry operations of point groups, the plane piezoelasticity theory of one- dimensional (1D) QCs with all point groups is investigated systematically. The gov- erning equations of the piezoelasticity problem for 1D QCs including monoclinic QCs, orthorhombic QCs, tetragonal QCs, and hexagonal QCs are deduced rigorously. The general solutions of the piezoelasticity problem for these QCs are derived by the opera- tor method and the complex variable function method. As an application, an antiplane crack problem is further considered by the semi-inverse method, and the closed-form so- lutions of the phonon, phason, and electric fields near the crack tip are obtained. The path-independent integral derived from the conservation integral equals the energy release rate. 展开更多

Obstructive sleep apnea-hypopnea syndrome(OSAHS)significantly impairs children's growth and cognition.This study aims to elucidate the pathophysiological mechanisms underlying OSAHS in children,with a particular focus on the alterations in cortical information interaction during respiratory events.We analyzed sleep electroencephalography before,during,and after events,utilizing Symbolic Transfer Entropy(STE)for brain network construction and information flow assessment.The results showed a significant increase in STE after events in specific frequency bands during N2 and rapid eye movement(REM)stages,along with increased STE during N3 stage events.Moreover,a noteworthy rise in the information flow imbalance within and between hemispheres was found after events,displaying unique patterns in central sleep apnea and hypopnea.Importantly,some of these alterations were correlated with symptom severity.These findings highlight significant changes in brain region coordination and communication during respiratory events,offering novel insights into OSAHS pathophysiology in children. 展开更多
