Field-assisted diamond cutting technology is a significant machining method that utilizes external energy fields to enhance the manufacturing performance.However,aimed the emergence of advanced high-performance materials,traditional single-field-assisted machining struggles to meet stringent precision requirements.Therefore,this study introduces an innovative and unique multi-energy field-assisted ultra-precision machining technology,in-situ laser-magnetic dual-field assisted diamond cutting(LMDFDC),to transcend the limitations of conventional single-field-assisted cutting methods and advance the machinability of challenging materials,notably the multi-principal-element high-entropy alloy(HEA).To elucidate the fundamental science questions of“what occurs,what changes,and what improves”in this work,the phenomenological behaviors of the dual-field coupling interaction are systematically investigated through advanced characterization techniques,spanning macroscopic surface integrity to microscopic atomic arrangement.This comprehensive study encompasses integrated analyses of four machining techniques for HEA workpiece,namely dual-energy field,two single-energy fields,and no-energy field.The research results indicate that the dual-field coupling effect demonstrates a leap in manufacturing performance through thermo-magneto-mechanical multi-physical synergistic interactions,primarily manifested in improved surface quality,reduced subsurface damage,suppressed diamond tool wear,and enhanced material removal stability.The significance of in-situ LMDFDC technology resides in propelling frontier academic developments in multi-physics coupled manufacturing theories while uncovering innovative machining approaches for next-generation high-performance materials. 展开更多

Since the introduction of advanced footwear technology(AFT),distance running performances have improved significantly,as evidenced by a series of world records and general improvements in both elite and recreational running performances.1 In their recent systematic review and meta-analysis,Stephen et al.2 synthesize evidence on how AFT as a whole,as well as longitudinal bending stiffness(LBS)and midsole energy return as key constructional features,affect running economy(RE)and ankle mechanics during running.2 Their systematic review demonstrates that AFT improves RE by∼2.7%at an average running speed of 14.5 km/h.In contrast,their synthesis of the currently available literature suggests that neither LBS nor energy return alone significantly improves oxygen consumption or alters ankle mechanics.The authors conclude that,instead,it is the interaction of these constructional features that drives relevant changes. 展开更多

Granular agricultural products constitute a staple food source for over 70%global population,are recognized as a core component within the food processing chain,and are accorded significant economic importance in international trade.Inadequate desiccation during harvest seasons is associated with the facilitation of mold proliferation,induction of germination processes,and acceleration of product deterioration.These outcomes are manifested through compromised food security and incurred economic losses.Nevertheless,the porous structural characteristics inherent to granular crops,combined with the stress fission challenges encountered during dehydration processes,render alternative methods such as solarization and hot air drying frequently inadequate for meeting crop-specific drying requirements.In this study,the implementation and relative merits of microwave and infrared drying technologies for granular crops have been systematically examined.Subsequently,the enhanced drying efficiency and quality parameters achieved through microwave-hot air,infrared-hot air,and infrared-microwave hybrid drying systems are quantitatively demonstrated in comparison with conventional single-mode drying approaches.A comprehensive synthesis is presented regarding experimental findings and research priorities associated with microwave-vacuum,far-infrared vacuum,and fluidized bed drying applications.The developmental potential of emerging desiccation technologies-including radio frequency,ohmic,and heat pump-based systems-was critically evaluated through the comparative analysis of dehydration kinetics,energy efficiency metrics,and product quality indices.A theoretical framework was established for optimizing the novel drying equipment and operational parameters.This systematic investigation contributes substantively to the realization of energy-efficient,low-carbon,and quality-preserving drying objectives,thereby providing crucial technical support for global food security initiatives and sustainable agricultural practices. 展开更多

Lung cancer takes the lead in terms of global cancer incidence and mortality rates.5′-adenosine monophosphate(AMP)-activated protein kinase(AMPK)serves as a universally conserved energy sensor throughout evolution checkpoint that orchestrates energy balance and metabolic homeostasis.However,AMPK activation has a complex,dual function in both the onset and advancement of lung cancer.Despite its protumorigenic effects,targeting AMPK with inhibitors to suppress cancer progression remains a critical area of research.An innovative high-content screening platform integrating small-molecule microarrays(SMMs)with oblique-incidence reflectivity difference(OI-RD)optical detection was established for AMPK inhibitor discovery.Alterations in the interfacial refractive index revealed that Ribavirin,an antiviral drug,has a high affinity for AMPK.Ribavirin binds directly to AMPK,suppressing its activation in mouse and human cells.By inhibiting AMPK phosphorylation,Ribavirin affects the downstream phosphorylation of mechanistic target of rapamycin complex 1(mTORC1)and eukaryotic translation initiation factor 4E(eIF4E)-binding protein 1(4EBP1),thereby regulating tumor cell proliferation and apoptosis.These results identify Ribavirin as a new AMPK inhibitor with potential utility in lung cancer therapy. 展开更多

Ensuring the income stability of relocated households is essential for advancing rural revitalization and achieving common prosperity.While existing research has explored the impact of digital technology on income,few studies have addressed how digital technology use affects income stability.To fill this gap,based on survey data from relocated households in 16 counties across 8 provincial-level regions in China,this study examines the impact of digital technology use on the income stability of relocated households using Ordinary Least Squares(OLS)and Propensity Score Matching(PSM).The results show that digital technology use improves both income and income stability,with stronger effects at higher levels of use.This impact is driven by better access to information acquisition and enhanced human capital.Additionally,digital technology helps stabilize the income of households facing downward volatility.The income stabilizing effect is particularly significant among relocated households in central regions,rural resettlement areas,and those with higher education levels.Furthermore,digital literacy amplifies the positive impact of digital technology on income stability.These findings offer valuable insights for policymakers aiming to promote digital technology use to ensure the income stability of relocated households and foster common prosperity. 展开更多

Backgrounds:South Korea is one of the world’s fastest-aging societies,facing significant challenges in maintaining healthcare quality and accessibility for its rapidly growing elderly population.This study extends the Technology Acceptance Model(TAM)by integrating health empowerment to examine its influence on digital healthcare device adoption among Korean older adults.Specifically,this study aims to investigate how health empowerment is associated with perceived usefulness and perceived ease of use,and how these perceptions subsequently relate to attitude and intention to use digital healthcare devices.Methods:Data were collected from 342 Korean older adults.The analysis followed Anderson and Gerbing’s two-stage approach,utilizing structural equation modeling to first evaluate the measurement model and subsequently examine the hypothetical path sequences across health empowerment,perceived usefulness,perceived ease of use,attitude,and behavioral intention.Results:The measurement model demonstrated satisfactory fit.Path analysis revealed that health empowerment significantly predicted both perceived usefulness(β=0.58)and perceived ease of use(β=0.43).Both perceived usefulness(β=0.58)and perceived ease of use(β=0.14)were significantly associated with attitude,which in turn was significantly associated with behavioral intention(β=0.77).The direct path from perceived usefulness to behavioral intention was not statistically significant.Overall,the model explained 63%of the variance in intention to use,which is generally considered strong explanatory power.Conclusions:Integrating empowerment into the TAM framework highlights the significance of autonomy and self-efficacy in the adoption process.The findings suggest that empowerment plays an important role in shaping older adults’perceptions of digital health technologies and their intention to adopt such devices,providing a conceptual basis for developing empowerment-driven strategies to facilitate the integration of digital health technologies among ageing populations. 展开更多

Reasonably controlling heat input is crucial for optimizing the weld quality of Mg alloys with thermal sensitivity.But it falls to meet diverse requirements of industrial welded structures.This study synchronously adjusts welding current,voltage and speed with constant heat input to achieve further regulation on weld quality of Mg alloy thin plate welded joints.Increasing three parameters significantly expanded melting width and area,with a lower heat-affected zone under full penetration.And equiaxed grains gradually replaced columnar grains at the fusion line.More precipitate phases formed in the weld zone at the same time,inducing a greater hardness.Moreover,higher arc energy promoted recrystallization,weakening the crystallographic texture and internal stress of welded joints.Especially at a wire feed rate of 7 m/min,the subgrain boundary content and kernel average misorientation were far lower than other joints.Although these evolutions had minimal impacts on tensile strength,elongation and yield strength exhibited a fluctuating state that initially decrease then raise.A superior tensile behavior was achieved at a wire feed rate of 6 m/min.The findings highlight significant impacts of varying welding parameters on weld quality under constant heat input,offering new insights for optimizing Mg alloy welding to meet diverse structural needs. 展开更多

Wafer-scale fabrication of high-performance microelectro-mechanical systems(MEMS)bio/chemical sensing chips remains constrained by the absence of reliable methods for integrating high-performance nanomaterials into suspended MEMS architectures.Here,a wafer-level manufacturing strategy is presented that redefines the MEMS process flow as“film first,cantilever later.”Through kinetically controlled self-assembly,wet-chemically synthesized Pd/SnO2nanospheres are transferred as dense,uniform monolithic films onto 8-inch wafers.An HfO2interface passivation patterning technology resolves long-standing incompatibility between functional sensing films and silicon substrates,enabling precise patterning and reliable integration on suspended MEMS cantilevers.The resulting Pd/SnO2MEMS H2 chips are fabricated onto an 8-inch wafer,demonstrating high sensitivity and consistency.This approach overcomes long-standing wafer-level manufacturing challenges in the formation and patterning of high-performance nanomaterials film,establishing a fully integrated wafer-level process that fundamentally redefines the manufacturing route for tetramethylammonium hydroxide-resistant nanomaterial-based MEMS sensing chips. 展开更多

Starting from the first principle thinking,this study systematically reviews the development mechanisms of gas reservoirs and proposes the development concept of“full life cycle enhanced gas recovery(EGR)”.Following the principles of scientificity,practicality and comparability,a generational classification system for EGR technologies is established.The research indicates that the properties of natural gas dictate a development mechanism primarily driven by pressure depletion to release the elastic expansion energy of gas.This leads to a development model centered on primary depletion,supplemented by limited adjustments in late stages.Early development essentially lies in well pattern optimization and risk pre-control,while late development focuses on targeted local adjustments and integrated collaborative control.Primary gas recovery,relying on natural energy depletion,achieves a recovery factor of 25%–55%.Secondary gas recovery,through active regulation of the reservoir pressure field via techniques like blockage removal,and injection-production optimization,can enhance the recovery factor by 10–15 percentage points.Tertiary gas recovery,employing multiple mechanisms to alter the reservoir's physical and chemical fields synergistically,offers a potential further increase of 5–10 percentage points.Currently,primary recovery technologies are mature and well-established.Synergistic optimization of well patterns and fracture networks enables effective production from gas-drive reservoirs,while optimized development strategies facilitate orderly production from water-drive gas reservoirs.Secondary recovery technologies,in the field pilot stage currently,adopt active measures like enhanced water drainage,water shutoff,and gas injection to effectively control water influx and release trapped gas.Tertiary recovery remains largely in the laboratory or pilot test stage.Future efforts should focus on cross-generational technologies,such as“primary+secondary”and“primary+tertiary”combinations,to continuously improve recovery factors throughout the full lifecycle of gas reservoirs. 展开更多
