Discussions about the future of energy sources and environmental sustainability are becoming critical on a global scale.The energy sector plays a central role in the economy,as the availability and cost of energy influence the competitiveness of economies,while the level of energy consumption impacts the standard of living for individuals.This paper aims to examine environmental challenges and steps for a sustainable transition towards a hydrogen economy,focusing on its potential as an alternative to fossil fuels and the importance of developing the hydrogen paradigm.The research methodology is based on a combination of qualitative and quantitative methods,including an analysis of global and regional trends in the energy transition,the impact of various forms of hydrogen production(green,blue,gray hydrogen)on greenhouse gas emissions,and a comparison of existing policies and strategies in different countries transitioning to a sustainable hydrogen economy.Research results show that green hydrogen,produced via electrolysis using renewable energy sources,holds the greatest potential for reducing greenhouse gas emissions,while gray and blue hydrogen can serve as transitional options.The development of the hydrogen paradigm,rooted in innovative technologies,renewable energy sources,and international cooperation,is crucial for decarbonization and the creation of a sustainable global economy,despite challenges such as high costs and the need for global coordination.The hydrogen paradigm is becoming a cornerstone of these efforts,laying the foundation for a long-term,sustainable global economy.Currently,over 180 hydrogen transport projects,60 distribution projects,80 storage projects,30 terminal and port projects,and more than 220 hydrogen production projects are under development worldwide.The global momentum of the hydrogen transition helps mitigate climate change and build a sustainable future. 展开更多

Research on tourism climate comfort is undergoing a paradigm shift from classic static assessment to intelligent dynamic sensing.Early models(such as temperature-humidity index and tourism climate index)established based on data of meteorological stations laid the foundation for the discipline but were unable to meet the dynamic demands of climate change,spatial heterogeneity,and individual experience.Global climate change is reshaping the landscape of tourism comfort and driving the assessment to shift towards future risk prediction.Downscaling technology becomes the key to connecting global scenarios and local assessments.Remote sensing and Internet of Things technologies have constructed a"sky-ground"collaborative sensing network,achieving a revolution in data acquisition.Artificial intelligence and big data analysis serve as the intelligent core to drive research from description to prediction.The new paradigm has significant potential in improving assessment accuracy and timeliness,but also faces challenges such as data integration,model interpretability,interdisciplinary integration,and ethical privacy.In the future,it is needed to develop interpretable AI,construct climate digital twins,and promote full-chain coupling research.This transformation is not merely an upgrade of methods,but a fundamental shift in the study of philosophy from an"environment-centered"perspective to an"experience-centered"one,providing key scientific support for sustainable tourism. 展开更多

BACKGROUND Research has consistently demonstrated that patients with major depressive disorder(MDD)exhibit attentional switching dysfunction,and the dual-task paradigm has emerged as a valuable tool for probing cognitive deficits.However,the neuroelectrophysiological mechanism underlying this deficit has not been clarified.AIM To investigate the event-related potential(ERP)characteristics of attentional switching dysfunction and further explore the neuroelectrophysiological mechanism of the cognitive processing deficits underlying attentional switching dysfunction in MDD.METHODS The participants included 29 MDD patients and 29 healthy controls(HCs).The ERPs of the participants were measured while they performed the dual-task para digm.The behavioral and ERP N100,P200,P300,and late positive potential(LPP)data were analyzed.RESULTS This study revealed greater accuracy in HCs and slower reaction times(RTs)in MDD patients.Angry facial pictures led to lower accuracy.The results also revealed shorter RTs for happy facial pictures and the longest RTs for the 500-ms stimulus onset asynchrony.With respect to ERP characteristics,happy facial pictures and neutral facial pictures evoked higher amplitudes.The N100,P200,P300,and LPP amplitudes at Pz were the highest.MDD patients had lower P200 mean amplitudes and LPP amplitudes than HCs did.CONCLUSION In conclusion,MDD patients exhibited abnormal ERP characteristics evoked by the dual-task paradigm,which could be the neural correlates of the known abnormalities in attentional switching in patients with MDD.These results provide valuable insights into the understanding of the neural mechanisms of attentional switching function and may guide targeted interventions in patients with MDD. 展开更多

Head and neck cutaneous squamous cell carcinoma(HNCSCC)remains underexplored compared to oropharyngeal squamous cell carcinoma,particularly in relation to human papillomavirus(HPV)and molecular markers such as p16 and p53.While p16 is a well-established surrogate for HPV in oropharyngeal cancer,our review highlights its unreliable role in HNCSCC,where positivity is instead associated with recurrence and metastasis.Similarly,p53 illustrates a dual role-wild-type as a genomic safeguard,mutated as an oncogenic driver-complicating prognostication.Methodological considerations,including the limitations of immunohistochemistry for HPV detection,underscore the need for multi-method and molecular validation in future studies.Ultraviolet radiation is posited as a key modifier of p16 function,decoupling expression from tumor suppression.To contextualize these findings,we draw parallels to glioblastoma(GBM),where subclonal evolution,p53 dysfunction,and intratumoral heterogeneity drive relapse despite aggressive multimodal therapies.GBM exemplifies how bulk-level biomarker generalizations often obscure dynamic cellular ecosystems,reinforcing the necessity of single-cell and spatial approaches.Multi-omics integration-encompassing genome,transcriptome,proteome,and tumor microenvironment mapping-coupled with single-cell RNA sequencing and spatial transcriptomics,offers a path forward for resolving subclonal dynamics in both HNCSCC and GBM.These technologies provide the resolution needed to track tumor-immunestromal co-evolution,identify therapy-resistant clones,and anticipate recurrence.We argue for a N-of-1,patient-and cell-centric paradigm that reframes biomarkers not as static surrogates but as dynamic readouts of cancer evolution across time and tissue contexts.Conceptually,we propose kinetic and microenvironmental frameworks(e.g.,“load-and-lock”barriers;dormancy and immunesynapse stabilization)as hypothesis-generating avenues to stall clonal handoffs and improve outcome prediction.Together,these perspectives argue for revised biomarker frameworks in HNCSCC and ethically inclusive,mechanism-anchored studies that bridge discovery with individualized care.By bridging insights from HNCSCC with the lessons of GBM,this review underscores the need for ethically inclusive,mechanistically informed frameworks that integrate subclonal evolution,biomarker re-interpretation,and precision-personalized hybrid models.Such an approach will be essential for advancing from one-size-fits-all strategies to individualized lifetime cancer care. 展开更多
