文摘The Yuncheng Basin,located in the southern part of the Fenwei Rift,North China,exhibits obvious crust thinning(Moho uplift of 6-8 km)and shallow Curie point depth(less than 18 km)and hence holds great potential for geothermal resources.However,geothermal exploration within the Yuncheng Basin typically faces significant challenges due to civil and industrial noise from dense populations and industrial activities.To address these challenges,both Controlled-Source Audio-frequency Magnetotellurics(CSAMT)and radon measurements were employed in Baozigou village to investigate the geothermal structures and identify potential geothermal targets.The CSAMT method effectively delineated the structure of the subsurface hydrothermal system,identifying the reservoir as Paleogene sandstones and Ordovician and Cambrian limestones at elevations ranging from−800 m to−2500 m.In particular,two concealed normal faults(F_(a)and F_(b))were newly revealed by the combination of CSAMT and radon profiling;these previously undetected faults,which exhibit different scales and opposing dips,are likely to be responsible for controlling the convection of thermal water within the Basin’s subsurface hydrothermal system.Moreover,this study developed a preliminary conceptual geothermal model for the Fen River Depression within the Yuncheng Basin,which encompasses geothermal heat sources,cap rocks,reservoirs,and fluid pathways,providing valuable insights for future geothermal exploration.In conjunction with the 3D geological model constructed from CSAMT resistivity structures beneath Baozigou village,test drilling is recommended in the northwestern region of the Baozigou area to intersect the potentially deep fractured carbonates that may contain temperature-elevated geothermal water.This study establishes a good set of guidelines for future geothermal exploration in this region,indicating that high-permeability faults in the central segments of the Fen River Depression are promising targets.

文摘Background MicroRNAs(miRNAs)are presented in the uterine lumen of many mammals,and in vitro experiments have determined that several miRNAs are important for the regulation of endometrial and trophoblast functions.Our aim was to identify and contrast the miRNAs present in extracellular vesicles(EVs)in the uterine lumen fluid(ULF)at the onset of attachment in cattle pregnancies(gestation d 18)initiated by artificial insemination(AI)or by the trans-fer of an in vitro-produced blastocyst(IVP-ET).A third group had no conceptus after the transfer of an IVP embryo.Results The abundance of 263 annotated miRNAs was quantified in the EVs collected from ULF.There was an increase in the transcript abundance of 20 miRNAs in the ULF EVs from the AI pregnant group,while 4 miRNAs had a lower abundance relative to the group not containing a conceptus.Additionally,4 miRNAs were more abun-dant in ULF EVs in the AI pregnant group relative to IVP-ET group(bta-mir-17,bta-mir-7-3,MIR7-1,MIR18A).Specific miRNAs in the ULF EVs were co-expressed with messenger RNAs expressed in extra-embryonic tissues and endome-trium,including genes that are known to be their targets.Conclusions The results provide biological insights into the participation of miRNAs in the regulation of trophoblast proliferation and differentiation,as well as in endometrium receptivity.The knowledge that in vitro cultured embryos can contribute to the altered abundance of specific miRNAs in the uterine lumen can lead to the development of cor-rective approaches to reduce conceptus losses during the first month of pregnancy in cattle.

文摘The behaviour of nanofertilizers(NFs)in plant-soil systems can differ from that of conventional chemical fertilizers due to their peculiar chemical-physical properties.Their effectiveness is still poorly understood.In this study,we evaluated the P fertilization potential of a novel nanosized FePO4NF(FePNF)in a plant-soil microcosm in a pot experiment.The efficacies of FePNF and a conventional P fertilizer(triple superphosphate,TSP)in sustaining the growth of cucumber plants were evaluated.Plants were grown for 28 d on a P-deficient soil,and determinations were made of plant growth parameters,mineral nutrient concentrations in plant tissues,P availability in soil,activities of soil enzymes involved in C,N,P,and S mineralization,and soil microbial community structure.No significant differences were found in plant dry weight,leaf area,chlorophyll content,or root growth between the FePNF and TSP treatments.Conversely,P availability in soil and P concentration in plant tissues at the end of the plant growth period were significantly higher after TSP fertilization compared to FePNF fertilization,whereas no significant differences were observed for other nutrients.Among the measured soil enzyme activities,there were no significant differences in the activities of soil acid phosphatase,β-glucosidase,and arylsulfatase between the FePNF and TSP treatments,while soil alkaline phosphatase activity was higher in the TSP treatment than in the FePNF treatment and the protease activity was higher in the FePNF treatment than in the TSP treatment.The FePNF and TSP treatments showed significant differences in soil archaeal,bacterial,and fungal community structures,although the microbial community profiles generally clustered closer to each other in the two treatments.We concluded that FePNF can be an efficient alternative to the conventional P fertilizer TSP.

文摘This paper explores how metaphors function as both cognitive blueprints and narrative building blocks,examining their role in shaping meaning through Antoine de Saint-Exupéry’s The Little Prince.Drawing on Lakoff and Johnson’s Conceptual Metaphor Theory(CMT)and Kövecses’Extended Conceptual Metaphor Theory(ECMT),the study analyzes two central metaphors:the rose as“LOVE IS A LIVING ORGANISM”and the desert as“LONELINESS IS EMPTINESS.”The rose metaphor,instantiated through care-oriented language(e.g.,“waters,”“protects”),activates nurturance schemas rooted in embodied experiences,framing love as a fragile organism requiring cultivation.Cross-linguistic variations in translations further reveal how cultural values filter universal cognitive structures.The desert metaphor evolves from a symbol of existential void(“no houses,no people”)to an epistemological threshold,with its transformation marked by sensory richness(e.g.,“hidden water”),exemplifying Bakhtinian chronotopic metamorphosis.Neurocognitive evidence(e.g.,fMRI studies)confirms that metaphor processing engages both language and sensorimotor brain regions,bridging cognitive science and literary analysis.These findings highlight metaphor as a dynamic nexus of language,thought,and culture,with implications for education,where metaphor serves as a cognitive scaffold for abstract reasoning.
文摘Jovani et al’s study contributes important evidence linking childhood trauma(CT)and parental socialization with at-risk mental state(ARMS)in non-clinical adolescents,demonstrating the mediating role of low levels of parental affection and communication in this relationship.This letter commends the study’s strengths while also identifying key issues that warrant further attention,including the limitations of cross-sectional design,potential perceptual biases,conceptual overlap between CT and parenting,and limited cultural generalizability.We advocate for longitudinal,culturally sensitive,and multi-informant approaches to further refine ARMS risk models,strengthen theoretical distinctions between CT and parenting,and inform targeted prevention strategies across diverse populations.We also extend the discussion by highlighting promising directions for future research.
文摘Chinese political discourse is the embodiment of the will of the people,the will of the CPC and the will of China.Conceptual metaphor is closely related to political discourse.Taking the 2022 government work report as an example,this paper discusses the metaphor problems in political discourse,and analyzes the metaphorical expressions and their functions in political discourse.Based on this,eco-translatology is used to analyze the translation strategies of metaphors in political discourse to help Chinese political discourse get better publicity.

文摘In the context of Industry 5.0,more emphasis is placed on human-centric smart manufacturing patterns.Product design is a vital phase of smart manufacturing,involving user engagement is an essential factor in enhancing design quality and fostering innovation.With user involvement in-depth,dynamically changing user requirements and feedback bring new problems to the design process,and the traditional linear solving process cannot perceive such variations timely,which causes hysteresis in the solution.The design solution's hysteresis affects the consensus achievement process between the designer and user,further prolonging the iteration cycle.To address this issue,a human-centric product conceptual design model is proposed for the timely translation of such variations into design solutions.In this model,design problems are formed by centering on user requirements,designer and user collaboratively solve the problems to form design solutions.Through a cycle of problem-driven,knowledgesupported,and solution evaluation,new problems are solved promptly to achieve progressive solution convergence,which clarifies the iterative evolution process and improves iterative efficiency.To verify the effectiveness of the model,a natural gas well foaming agent automatic filling device design is presented.
文摘The phenomenon of verbal-to-nominal shift(hereafter referred to as“V-N shift”)exists in both English and Chinese.It reflects both the universal conceptual metonymic thinking and the principle of linguistic economy.Focusing on conceptual metonymy theory and combined with the Event Idealized Cognitive Model(ICM),this paper systematically compares the V-N shift phenomenon in English and Chinese.The study shows that English and Chinese V-N shifts share the core cognitive mechanism of“conceptual proximity within the Event ICM”,while significant differences exist in type distribution and usage frequency.This analysis not only helps deepen the understanding of the cognitive logic behind English and Chinese V-N shifts but also provides a new perspective for the study of word-class conversion and the relationship between language and thinking.
