The integration of High-Altitude Platform Stations(HAPS)with Reconfigurable Intelligent Surfaces(RIS)represents a critical advancement for next-generation wireless networks,offering unprecedented opportunities for ubiquitous connectivity.However,existing research reveals significant gaps in dynamic resource allocation,joint optimization,and equitable service provisioning under varying channel conditions,limiting practical deployment of these technologies.This paper addresses these challenges by proposing a novel Fairness-Aware Deep Q-Learning(FAIRDQL)framework for joint resource management and phase configuration in HAPS-RIS systems.Our methodology employs a comprehensive three-tier algorithmic architecture integrating adaptive power control,priority-based user scheduling,and dynamic learning mechanisms.The FAIR-DQL approach utilizes advanced reinforcement learning with experience replay and fairness-aware reward functions to balance competing objectives while adapting to dynamic environments.Key findings demonstrate substantial improvements:9.15 dB SINR gain,12.5 bps/Hz capacity,78%power efficiency,and 0.82 fairness index.The framework achieves rapid 40-episode convergence with consistent delay performance.These contributions establish new benchmarks for fairness-aware resource allocation in aerial communications,enabling practical HAPS-RIS deployments in rural connectivity,emergency communications,and urban networks. 展开更多

The sensitivity and quantification capability of surface-enhanced Raman scattering(SERS)substrates are mutually exclusive,because the ultrasensitive SERS sites(hottest spots)necessary for the sensitivity will significantly magnify the SERS signals of the analyte molecules and thus each of these molecules will be miscounted to be hundreds during the quantification process.We demonstrate a concept to circumvent the above contradiction by engineering a timeshare SERS platform capable of working at the quantitative or the sensitive mode on demand.The timeshare SERS platform was constructed by transferring a monolayer gold nanosphere film onto elastic substrates(e.g.,hydrogel).The volume change of the hydrogel could adjust the inter-nanosphere distance,dynamically controlling the formation or extinction of the SERS hottest spots on the same SERS substrate without influencing the spatial distribution of the analyte molecules.The timeshare SERS platform without the SERS hottest spots showed strong quantification capability,while when equipped with a substantial number of the SERS hottest spots exhibited ultrahigh sensitivity.We demonstrated quantitative and ultrasensitive detection of various analyte molecules using the quantitative and the sensitive mode of the timeshare SERS platform,respectively.We opened an avenue towards designing SERS substrates with both high sensitivity and strong quantification capability. 展开更多

In the context of global warming,the increasing frequency of extreme weather events,meteorological disasters,and regional pollution events highlights the urgent need for targeted atmospheric observations in ecologically sensitive regions.The atmospheric boundary layer top remains a critical yet under-observed interface in climate and environmental research.To respond to this need,the Atmospheric Boundary Layer Eco-Environment Shanghuang Observatory(ABLES)was established in 2023 by the Institute of Atmospheric Physics,Chinese Academy of Sciences in Jinhua,southeastern China.As a high-altitude,state-of-the-art research platform,ABLES addresses the critical need for comprehensive atmospheric and environmental observations in East Asia.The observatory facilitates interdisciplinary research focusing on three core areas:(1)cross-sphere transport of pollutants between atmospheric layers and its environmental and climatic impacts;(2)physical and chemical interactions between clouds and aerosols under extreme weather conditions;and(3)multiscale feedback mechanisms between climate change and ecosystems.ABLES is also aimed at revealing long-term patterns in greenhouse gases,ozone depleting substances,and cloud properties,and to elaborate the formation mechanisms of severe weather events such as thunderstorms and freezing rain.The findings at ABLES will support advances in weather forecasting,air quality modeling,and adaptive strategies for climate resilience.As part of China's growing environmental monitoring network,ABLES has been collaborating with various research organizations,serving as a cooperative research platform for technological development and evidence-based environmental policymaking. 展开更多

X-ray free electron laser(XFEL)plays a critical role in diagnosing dynamic compression processes in micro-and meso-scale materials.To deepen our understanding of XFEL physics and optimize facility design,a preliminary XFEL experimental simulation platform was developed based on the highperformance computing(HPC)simulation workflow application platform(HSWAP).HSWAP provides workflow,component,and data linkage models for XFEL experiments,enabling flexible simulation of diverse processes through modular configurations.This platform was employed to investigate X-ray diffraction(XRD)of microscale materials and phase contrast imaging(PCI)of meso-scale explosive samples.Simulation results for XRD of a metallic sample under shock loading and PCI of voids in explosive materials demonstrate the platform’s ability to accurately reproduce experimental dynamics.By integrating numerical models with data analysis,the platform enhances the design of XFEL experiments and provides a foundation for interpreting diagnostic capabilities in ultrafast processes.Future work will focus on refining simulation methods for meso-scale samples using phase-field approaches and high-Z materials under shock conditions. 展开更多

During maritime navigation,the operational reliability of onboard communication and radar equipment systems is disrupted by wave-induced vessel motions.To ensure the stable performance of these critical systems,a marine dual-axis compensation platform is developed for active roll and pitch motion compensation.However,the stochastic nature of wave disturbances and the nonlinear characteristics of permanent magnet synchronous motors significantly complicate precise motion compensation.To address these limitations,a triple-loop coordinated controller architecture is proposed in this study.In this architecture,the outer position loop implements linear active disturbance rejection control(LADRC)to estimate and compensate for total position disturbance.A sliding mode control(SMC)-based velocity loop facilitates steady velocity adjustment,whereas an inner current loop leverages internal model control(IMC)to decouple cross-coupled electromotive forces and simplify parameterization.Simulation results for vessel motion reveal that the proposed LADRC-SMC-IMC hybrid system enhances compensation accuracy and stability by approximately 46.6%and 39%,respectively,compared with the triple-loop proportional-integral(PI)controller.Experimental validation of the simulation results confirms that the proposed system improves compensation accuracy by approximately 21.8%,exhibiting comparable compensation stability with that of the PI controller.Actual vessel tests confirm that the LADRC-SMC-IMC controller effectively compensates for vessel motion disturbances under Sea State II conditions.Notably,the numerical simulations and physical experiments confirm the effectiveness and viability of the architecture,underscoring its substantial application potential for marine motion compensation systems. 展开更多

Cultural eutrophication,driven primarily by anthropogenic activities,poses a severe threat to freshwater biodiversity.Aimed to evaluate how nutrient elements affect the phytoremediation potential of floating-bed plants and to assessed select optimal species for ecological restoration.We investigated the functional traits of three floating-bed plants—edible Oenanthe javanica,Ipomoea aquatica,and ornamental Myriophyllum aquaticum—in Qiandaohu Lake,an oligo-mesotrophic reservoir in China.A mesocosm experiment was conducted using different eutrophic nitrogen(N)and phosphorus(P)concentrations.Plant functional traits[shoot,root,and total biomass,relative growth rate(RGR),and maximum quantum yield of photosystemⅡ(Fv/Fm)]and plant net N and P purification efficiency(μ)were measured.The results revealed that plant species significantly influenced all the traits,with P exerting a stronger effect than N;thus,P was identified as a critical limiting factor for growth and remediation performance,underscoring its role in cultural eutrophication.Specifically,M.aquaticum exhibited optimal eutrophication purification efficiency at high N and P concentrations.However,as an introduced non-invasive plant,M.aquaticum should be used cautiously for phytoremediation.This study highlights the application of floating-bed platforms in oligo-mesotrophic reservoirs,bridging ecological restoration with socioeconomic value. 展开更多

Appropriate resource scheduling is the key to achieving the best performance of Low Earth-Orbit(LEO)Multi-Target Tracking(MTT)for the Space-based Radar Networks(SBRN)system.The high-velocity nature of satellites imposes high demands on the convergence rate of filtering and tracking accuracy while escalating the complexity of dynamic scheduling.To address these challenges,this paper utilizes Two-Line Elements(TLE)information to fully exploit the limited power-aperture resource of space-based Colocated Multiple-Input Multiple-Output(C-MIMO)radar and constructs a Walker constellation SBRN system.On this basis,a cognitive distributed cooperative tracking framework with fusion feedback mechanism is proposed.Each node can serve as the fusion center,achieving optimal fusion through the Fast Covariance Intersection(FCI)criterion while reducing the communication requirements.The global outcomes are fed back to all local nodes which can hasten the convergence rate of target state estimation.To maximize the global MTT performance,a closed-loop Joint Multi-Dimensional Resource Scheduling(JMDRS)strategy that considers multi-coverage conditions and visible windows is established.Moreover,the Posterior Cramer-Rao Lower Bound under Global Fusion Feedback(GF-PCRLB)is derived to provide a quantifiable metric for the overall performance.Finally,a fast suboptimal solution to the nonconvex model is proposed based on cross-iterative dimension reduction and variable decoupling.It introduces the tracking Efficiency-to-Cost Ratio(ECR)to jointly decide the beam pointing as well as the transmit power and fusion weight of each beam.Numerical results demonstrate that the proposed method significantly outperforms the existing approaches in enhancing the MTT performance of the SBRN system. 展开更多

OBJECTIVE:To identify candidate biomarkers of blood stasis syndrome(BSS)associated with coronary artery disease(CAD)and explore the underlying inflammatory mechanisms.Methods:Using the Olink Target 96 Inflammation panel,we identified plasma proteins in a group of 88 patients comprised of healthy controls(HCs),those with CAD and BSS(CAD-BSS),those with CAD without BSS(CADnon-BSS),and those with BSS without CAD(non-CADBSS)(n=22 in each group).Protein molecules that were specifically expressed in CAD or BSS were identified by differential expression analyses.Subsequently,potential protein biomarkers were identified using least absolute shrinkage and selection operator regression to enable CAD and BSS differentiation.The potential functional mechanisms of identified proteins were then determined by Gene Ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses.RESULTS:Patients with CAD had 31/92 upregulated and 4/92 downregulated proteins compared with those without.Chemokine(C-C motif)ligand 11(CCL11),CUB domain-containing protein 1,hepatocyte growth factor,sirtuin 2(SIRT2),eukaryotic translation initiation factor 4E-binding protein 1(4E-BP1),CCL25,and tumor necrosis factor(TNF)showed the strongest upregulation(all P<0.0001).Patients with BSS had 8/92 downregulated proteins,specifically CCL28,CCL11,cystatin D,STAM-binding protein,4E-BP1,matrix metalloproteinase-10,SIRT2,and monocyte chemotactic protein 4,compared with those without(all P<0.05).The CAD-BSS group had one interleukin-17(IL-17)upregulated and 10/92 downregulated proteins compared with the CAD-non-BSS group.When compared with the non-CAD-BSS group,the CAD-BSS group had 8 upregulated proteins but only 2 downregulated proteins,namely interleukin-10 receptor subunit alpha(IL-10RA)and TNF-related activation-induced cytokine(both P<0.05).Totally 10 proteins were identified as potential candidate biomarkers of BSS in CAD patients.After least absolute shrinkage and selection operator regression analysis,two proteins that distinguished between BSS and non-BSS individuals among CAD patients were identified(SIRT2 and 4E-BP1).These proteins are primarily associated with the mechanistic target of rapamycin signaling pathway,which regulates inflammation and oxidative stress.CONCLUSIONS:Results suggest that the inflammatory response and mechanistic target of rapamycin signaling pathway participate in CAD and BSS development,and that SIRT2 and 4E-BP1 are prospective protein biomarkers for patients with CAD and BSS. 展开更多

Digital technology transforms and represents intangible cultural heritage(ICH)into shareable and reproducible digital forms,exerting a profound impact through digital platforms on its inheritance and development,which traditionally rely on immediacy and physical presence.Against the backdrop of the internet and accelerated social mobility,in which the fluidity of time and space has become a hallmark of modern society,the platform logic of digital ICH serves as a critical lens to examine the phenomena of“disembedding”and“re-embedding”in the digital era.From the perspective of“disembedding,”digital platforms facilitate the spatiotemporal displacement of ICH’s living spaces,the multidimensional expansion of ICH discourse narratives,and the popularization of regional group cultures.From the perspective of“re-embedding,”influenced by factors such as national strategic guidance,the prevalence of digital platforms,the rise of cultural consumption,and the awakening of local cultural consciousness,digital ICH undergoes value reconstruction in its contemporary inheritance and development.It transforms from remnants of lived experience into capital,culture,and emotion that resonate with contemporary individuals,thereby“re-embedding”into the daily lives of the public and achieving dynamic inheritance and development in the context of the new era. 展开更多

Portable ratiometric fluorescent platforms have emerged as promising tools for multifarious detection,yet remain unexplored for point-of-care monitoring doxorubicin(DOX),one of clinically antineoplastic drugs.To this end,we herein develop a portable self-calibrating platform namely carbon dots(C-dots)-embedded hydrogel sensors with a smartphone-assisted high-throughput imaging device,for DOX sensing.The prepared green-emitting(λem=508 nm)and negatively-charged C-dots(−11.40±1.21 mV),which have sufficient spectral overlap with the absorption band of DOX(∼500 nm),can strongly bind with positively-charged DOX molecules by electrostatic attraction effects.As a result,DOX molecules are selectively and rapid(20 s)determined with a detection limit of 10.26 nmol/L via Förster resonance energy transfer processes,demonstrating a remarkably chromatic shift from green to red.Further integrated with a 3D-printed smartphone-assisted device,the platform enabled high-throughput quantification,achieving recoveries of 96.40%-101.85%in human urine/serum(RSDs<2.94%,n=3).Notably,the dual linear detection ranges of the platform align with the reported clinical DOX concentrations in urine and plasma(0-4 h post-administration),validating their capability for direct quantification of DOX in clinical samples without special pre-treatment processes.By virtue of attractive analytical performances and robust feasibility,this platform bridges laboratory precision and point-of-care testing needs,offering promising potential for personalized chemotherapy and multiplexed analyte screening. 展开更多

Jacket offshore platforms are commonly subjected to wave loading,which induces undesirable structural vibrations and can lead to integrity issues,including failure or collapse.This study investigates the mitigation of wave-induced vibrations in jacket offshore platforms using inerter-based tuned mass damper(ITMD)systems.A theoretical model of the platform equipped with ITMDs,subjected to realistic wave loading,is developed,and its dynamic responses across various sea states are analytically determined.To ensure practical applicability,a performance-oriented optimization is conducted to identify the optimal ITMD parameters,with deck displacement minimization as the primary objective.A parametric analysis examines the influence of ITMD parameters on the platform’s dynamic behavior.The effectiveness of the ITMD system in suppressing vibrations is assessed and compared directly with that of a conventional tuned mass damper(TMD).Results indicate that the optimized ITMD system outperforms the traditional TMD in reducing both deck displacements and inter-story drifts,achieving superior performance with a lower system mass.The ITMD is therefore concluded to be a promising solution for vibration control in jacket offshore platforms. 展开更多

Paired electrochemical valorization reactions(EVRs)offer a sustainable route for co-producing value-added chemicals,yet their efficiency is hindered by overlapping potential windows with water electrolysis reactions(WER).Here,an asymmetric CuOx@Ag electrocatalyst platform is proposed that decouples both anodic and cathodic EVRs from WER via Ag-mediated oxophilicity modulation.Atomic-level Ag incorporation suppresses*OH/H2O adsorption and widens the potential windows to 422 mV(anode)and 502 mV(cathode)in a glycerol oxidation|4-nitrophenol reduction pair.The system achieves>90%Faradaic efficiency and>70 mmol h-1cm-2productivity.In situ and DFT analyses reveal that Ag-induced weakening of Cu-O interactions underlies the WER suppression mechanism.Techno-economic and life-cycle evaluations indicate 31.6%cost reduction and 57.4%lower CO2emissions versus thermochemical routes.The CuOx@Ag platform thus provides a scalable and general strategy for low-carbon electrosynthesis across diverse redox systems. 展开更多
