Following the proposal of the“Emerging Engineering Education(EEE)”initiative,the cultivation of interdisciplinary innovative talents has gained increasing prominence.Currently,there exists a significant gap between the practical innovation capabilities of automotive majors in vocational colleges and the evolving demands of the industry.To address deficiencies in interdisciplinary innovative talent development programs,this study proposes an educational framework structured around“One Core,Two Dimensions,Three Levels.”Leveraging a project-driven teaching methodology and utilizing CATIA—the industry-standard 3D design software—as a central tool,we have developed a closed-loop teaching model integrating theory,modeling,simulation,and evaluation.This model underpins a newly designed automotive engineering practicum aimed at nurturing high-quality engineering talents equipped with three critical competencies:solving complex engineering challenges,digital design proficiency,and cross-disciplinary collaborative innovation.The proposed approach demonstrates potential to alleviate the structural disconnect between traditional engineering pedagogy and industry talent requirements. 展开更多

Under the background of information technology in education,there is insufficient integration of technological knowledge,pedagogical knowledge,and subject content knowledge in the teaching of propositions in high school mathematics.Teachers mostly equate information technology with multimedia presentations,and students often memorize formulas mechanically,which leads to difficulties in the application of complex propositions.In this study,we take“the cosine formula of the difference between two angles”as an example.Based on the TPACK framework,we use contextual teaching and geometric drawing board demonstration to integrate subject content,pedagogical knowledge,and technological knowledge in teaching design and practice.It is found that by dynamically displaying the derivation process of the formula and guiding students to explore independently,it can help them understand the logic of the formula and improve their application ability.This study provides a paradigm for teaching propositions in high school mathematics and suggests that the TPACK framework can facilitate knowledge integration and cultivate students’mathematical literacy such as problem posing and creative inquiry,which is of great significance for teaching practice. 展开更多

A“smart course”denotes a learner-centered curriculum model that deeply integrates advanced technologies,including generative artificial intelligence(AI)and big data analytics,with ongoing optimization and iterative refinement.This paper examines the pathways of smart course development in higher vocational education by using the Study Tour Course Design course as a practical case study.The analysis is conducted from four perspectives:innovation in educational concepts,innovation in teaching models,transformation in learning paradigms,and enhancement in evaluation systems.By developing a threedimensional framework encompassing“knowledge,skills,and problems”,the focus of education shifts from“knowledge imparting”to“competency development”.This approach fosters a transformation in teaching interactions,moving beyond the traditional“teacher and student interaction”to a more integrated trinity collaboration of“teachers,students,and machines”,and promotes the transformation of students’learning from“passive receptive learning”to“autonomous inquiry-based learning”.Simultaneously,it facilitates the transition of evaluation methods from“outcome-based evaluation”to“multi-dimensional evaluation”. 展开更多

Objective:The incidence and mortality of colorectal carcinoma(CRC)continue to rise globally,highlighting the need to identify modifiable risk factors for early detection and prevention.Previous studies have demonstrated significant associations between CRC risk and various serum metabolites as well as inflammatory cytokines;however,due to limitations in study design and potential confounding factors,the causal relationships remain unclear.This study aims to investigate the causal relationships between inflammatory cytokines,serum metabolites,and CRC risk,providing a theoretical basis for the development of novel early diagnostic biomarkers and therapeutic targets.Methods:A two-sample Mendelian randomization(MR)design was applied using summary statistics from genome-wide association studies(GWAS).Instrumental variables(IVs)were derived from:1)metabolomics GWAS data of 1400 serum metabolites(n=8299);2)cytokine GWAS data of 91 inflammatory factors(n=14824);and 3)CRC risk data from the FinnGen consortium(6847 cases and 314193 controls).The primary analysis was conducted using the inverse-variance weighted(IVW)method,with sensitivity analyses performed using MR Egger regression and the weighted median method.Effect estimates including odds ratios(OR),95%confidence intervals(CI),and false discovery rates(FDR)were calculated.Results:MR analysis indicated that higher levels of axin-1(AXIN1)(OR=0.84195%CI 0.714 to 0.991)and Fms-related tyrosine kinase 3 ligand(Flt3L)(OR=0.916,95%CI 0.844 to 0.994)were associated with a reduced risk of CRC.In contrast,higher levels of Delta/Notchlike epidermal growth factor-related receptor(DNER)(OR=1.119,95%CI 1.009 to 1.241)and vascular endothelial growth factor A(VEGF-A)(OR=1.078,95%CI 1.011 to 1.150)were associated with an increased risk of CRC(all P<0.05).Metabolomics association analysis further identified 144 serum metabolites significantly correlated with these four key inflammatory cytokines(FDR<0.05),suggesting that they may regulate CRC risk through inflammatory pathways.Conclusion:Specific inflammatory cytokines and serum metabolites have causal relationships with the risk of CRC.These findings provide insights for further exploration of potential risk factors and the development of effective prevention strategies for CRC. 展开更多

In molybdenum chemistry,the oxidative addition of o-quinone or 1,2-dicarbonyl compounds to molybdenum has been widely used in Mo-catalyzed C—C bond construction.The carbonyl oxidative addition to Mo(0)or Mo(Ⅱ)is the critical elementary reaction of molybdenum catalysis.However,the relevant density functional theory(DFT)studies are relatively scarce,especially regarding the rational selection of functionals.In this work,14 functionals were employed to investigate the Mo-catalyzed carbonyl oxidative addition step.A benchmark study was carried out to evaluate their performance in structure optimization and energy calculation.Analyses of mean absolute error(MAE)and mean squared error(MSE)indicated that the B3LYP-D3(BJ),TPSSh,and ωB97X-D functionals exhibited superior performance in structure optimization.Using the DLPNO-CCSD(T)functional as the reference,the M06,M06-L,and MN15-L functionals exhibited good performance for energy calculation based on the structures optimized using the B3LYP-D3(BJ)functional.In particular,MN15-L provided the best performance with the smallest MAE and MSE. 展开更多

Objective Frailty is becoming increasingly common among aging adults.Frailty transitionis shaped by biological,social,psychological,and environmental factors.This study investigated combined effects of protective factors on frailty transition by constructing a Protection Index(PI)to guide targeted interventions.Methods Data were extracted from the 4th Sample Survey of the Aged Population in Urban and Rural China,including baseline(2017)and follow-up(2019)surveys.Frailty was assessed using the Frailty Index(FI),whereas the PI measured protective factors.Frailty transitions over 2 years were analyzed prospectively.Pearson’s correlation examined the relationship between FI and PI,and logistic regression assessed the effects of PI on frailty transitions.Results This study included 9,093 older adults.FI values increased with age and were higher in women,whereas PI values decreased with age and were higher in men.Over 2 years,56.2%of the participants showed a stable frailty status,14.2%improved,and 29.6%worsened.Negative transitions were more common than positive transitions,with transitions occurring most frequently between adjacent states.The PI was moderately negatively correlated with the FI(r=−0.349,P<0.001).A higher PI was associated with a lower risk of negative transitions among robust and prefrail individuals(OR=0.989,0.981,both P<0.05),but showed no significant effect among those with existing frailty.Conclusion Negative frailty transitions were more common with advancing age.Enhancing PI may help prevent negative frailty transitions among robust and pre-frail older adults,underscoring the value of early interventions. 展开更多

The development of wheat cultivars with improved nitrogen(N),phosphorus(P),and potassium(K)use efficiency is essential for sustainable agriculture.Genetic dissection and identification of causative genes underlying nutrient use efficiency represent a key strategy toward this goal.We conducted an extensive genome-wide association study(GWAS)using a panel of 431 wheat cultivars,identifying 1,659 significant single-nucleotide polymorphisms(SNPs)(LOD>5)through genotyping-by-sequencing.This analysis revealed 534 quantitative trait loci(QTLs)associated with 12 nutrient use efficiency traits across five distinct environments,among which 14 QTLs were consistently detected in at least three environments.Notably,meta-QTL analysis,showed that QTL80(72.12–74.24 Mb,chr2A),QTL387(32.88–33.56 Mb,chr6A),and QTL500(535.53–540.80 Mb,chr7B)exhibit clear co-localization with MQTL-2A-2,MQTL-6A-1,and MQTL-7B-2,respectively.This overlap highlights their robustness across diverse environmental conditions.Within these regions,critical candidate genes-including members of the bZIP transcription factor family and a potassium transporter gene-were identified in relation to nutrient use efficiency.Furthermore,a novel locus,QTL234,was discovered,harboring key candidate genes such as dof zinc finger protein,Ankyrin repeat family protein,and cytochrome P450.To validate the SNP within QTL234 associated with nitrogen harvest index(NHI),we developed a dCAPS marker for AX-109095537.These findings demonstrate the effectiveness of high-resolution SNP-based GWAS in rapidly pinpointing promising candidate genes.They also establish a foundation for large-scale QTL fine mapping,candidate gene validation,and the development of functional markers essential for enhancing nutrient use efficiency in wheat breeding programs. 展开更多
