The rapid evolution of large language models(LLMs)towards autonomous Agentic artificial intelligence(AI)necessitates a systemic overhaul across algorithms,infrastructure,and architectures.This paper presents a unified view of the“Agentic AI Infrastructure,”connecting research threads often studied in isolation.First,post-training algorithms are reviewed,contrasting traditional reinforcement learning(RL)with emerging reasoning-centric methods and test-time scaling strategies.Next,the transition of RL training frameworks is analyzed from monolithic,colocated designs to disaggregated,asynchronous architectures tailored for the extreme variance of agentic rollouts.Furthermore,progress in agent construction is synthesized,covering reflection,planning,tool use,and multi-agent collaboration.By integrating these layers,the paper elucidates how agentic AI systems impose unique demands on underlying training systems.Finally,open challenges are outlined by covering capability scaling,efficiency,safety,privacy,and governance for reliable realworld agentic AI deployment. 展开更多

Polymer hydrogels with variable stiffness demonstrate immense practical application value,particularly when utilizing water as a trigger medium,which significantly expands their prospects in soft robotics,bioelectronics,and artificial muscles.However,existing water-induced stiffening hydrogel rely on ionic liquids and inorganic salts,posing leakage risks during prolonged use.Here,we proposed a strategy for mechanically strengthening hydrogel through water-induced phase separation.By designing a polymer matrix featuring hydrophilic oligomeric ethylene glycol methacrylate(OEGMA)and hydrophobic methyl methacrylate(MMA)moieties,this poly[methyl methacrylate-co-poly(ethylene glycol)methacrylate][P(MMAx-co-OEGMAy)]hydrogel exhibited reversible stiffness switching across four orders of magnitude(from 1.88×10-2MPa to201.63 MPa)upon water stimulation.This abrupt stiffness enhancement stemmed from strong hydrogen bonding between water molecules and hydrophilic OEGMA segments,facilitating spontaneous aggregation and phase separation of hydrophobic MMA segments.The resulting hydrophobic MMA domains formed dynamic physical crosslinking points,thereby enhancing the hydrogel's stiffness.Furthermore,the hydrogel exhibited a time-dependent,multi-stage stiffness enhancement during water swelling.As proof of concept,it was employed as a shape-memory component to explore its application in the controllable programming of multi-stage complex shapes,offering novel design insights for developing environmentally friendly,high-mechanical-performance smart hydrogel materials. 展开更多

BACKGROUND Patients with gallbladder carcinoma(GBC)often report abdominal pain,which is particularly severe,difficult to treat,and insufficiently relieved.Interleukin-33(IL-33)/suppression of tumorigenicity 2(ST2)signaling plays a role in cancer and pain,but its role in GBC-induced chronic pain is still unknown.AIM To investigate the potential effects of IL-33/ST2 signaling on GBC-induced cancer pain.METHODS To establish a GBC-induced chronic pain model,the GBC cell line GBC-SD was implanted into the gallbladder of nude mice.Pain-related behavior was determined by evaluating withdrawal behavior in response to mechanical stimuation.Serum samples from patients were analyzed via enzyme-linked immunolsorbent assay.Spinal cord samples from the rodents were subjected to enzyme-linked immunosorbent assay,western blotting and quantitative real-time polymerase chain reaction.RESULTS Nude mice with GBC-induced chronic pain presented significant spontaneous visceral pain-related behavior and abdominal hypersensitivity to mechanical stimuli.We demonstrated a significant increase in IL-33 levels in patient serum and in the spinal cords of GBC-induced chronic pain model mice.IL-33/ST2 signaling activation in the spinal cord may promote GBC-induced chronic pain.Remarkable activation of astrocytes and microglia as well as increased levels of proinflammatory cytokines was observed in the spinal cords of the mice.A significant decrease in the activation of astrocytes and microglia and the levels proinflammatory cytokines was observed following the blockade of IL-33/ST2 signaling.CONCLUSION Blockade of spinal IL-33/ST2 signaling results in a significant reduction in GBC-induced pain-related behaviors.This study suggested that targeting IL-33/ST2 signaling may relieve chronic cancer pain due to GBC. 展开更多

Autonomous self-hosted AI agent platforms are rapidly evolving from prompt-response assistants into persistent systems that can maintain long-lived state,invoke tools,ingest external content,and execute environment-changing actions.While this transition enables practical automation,it also introduces lifecycle security risks that cannot be fully explained by prompt-level analysis alone.In this paper,a security analysis of OpenClaw is presented,with OpenClaw serving as a representative autonomous agent operating environment and a concrete case study for broader security challenges in emerging agent ecosystems.A trust-boundary-first perspective is adopted to examine how attacks propagate across five boundary classes:ChannelAccess,Session-and-State,Tool-Execution,External-Content,and Extension Supply-Chain.The results presented in this paper show that threats such as indirect prompt injection,memory poisoning,unsafe tool invocation,data exfiltration,and malicious skill abuse are not isolated anomalies;rather,they are stage-specific manifestations of a common systems problem in which untrusted influence progressively crosses into higher-privilege contexts.Based on this analysis,the defense-in-depth implications for OpenClaw deployments are discussed,including boundary-aware isolation,capability-scoped tool mediation,memory integrity controls,extension governance,and evidence-oriented operational oversight.This study provides a practical framework for evaluating and hardening long-running,tool-capable,autonomous AI agents in realistic deployment settings. 展开更多

Biochar amendment is considered a potential strategy to improve soil fertility and mitigate climate change,yet its specific effects on the fate of fertilizer-derived and native soil nitrogen remain unclear.To elucidate the effect of biochar amendment on soil nitrogen(N)transformation and nitrous oxide(N2O)emission,a 56-d soil incubation experiment was conducted using15N isotope tracing to monitor the fate of N.Three treatments were set up:ⅰ)no addition of N or biochar control(CK),ⅱ)addition of15N-labeled ammonium sulfate((NH4)2SO4)(NS),andⅲ)combined addition of15N-labeled(NH4)2SO4and biochar(NS+BC).The15N abundances in soil ammonium(NH4+),nitrate(NO3-),microbial biomass N(MBN),particulate organic N(PON),mineral-associated total N(MTN),and N2O were measured.Compared with NS,endogenous soil N-derived NH4+-N and N2O decreased significantly by 34.4%-67.6% and 18.3%-51.2%,respectively,and exogenous N-derived NH4+-N,MTN,and N2O decreased significantly by 49.6%-81.4%,15.0%-47.0%,and 42.3%-76.5%,respectively,in NS+BC during the first 14 d.Biochar amendment significantly increased endogenous and exogenous soil N retention in MBN by 16.7%-40.1% and over 200 times,respectively,during the first 21 d.The endogenous and exogenous soil N retention in PON increased by12.5%-27.0% and 18.2%-78.5%,respectively,over the whole incubation period.For MTN,the endogenous and exogenous soil N retention increased by 3.9%-6.1% and 24.9%-30.6%,respectively,from days 21 to 56.The contribution of endogenous N to the total N2O emission was>80% across treatments.These results show that biochar amendment can mitigate soil N2O emission and promote inorganic N translocation into MBN,PON,and MTN in soil. 展开更多

Pulsed dynamic electrolysis(PDE),driven by renewable energy,has emerged as an innovative electrocatalytic conversion method,demonstrating significant potential in addressing global energy challenges and promoting sustainable development.Despite significant progress in various electrochemical systems,the regulatory mechanisms of PDE in energy and mass transfer and the lifespan extension of electrolysis systems,particularly in water electrolysis(WE)for hydrogen production,remain insufficiently explored.Therefore,there is an urgent need for a deeper understanding of the unique contributions of PDE in mass transfer enhancement,microenvironment regulation,and hydrogen production optimization,aiming to achieve low-energy consumption,high catalytic activity,and long-term stability in the generation of target products.Here,this review critically examines the microenvironmental effects of PDE on energy and mass transfer,the electrode degradation mechanisms in the lifespan extension of electrolysis systems,and the key factors in enhancing WE for hydrogen production,providing a comprehensive summary of current research progress.The review focuses on the complex regulatory mechanisms of frequency,duty cycle,amplitude,and other factors in hydrogen evolution reaction(HER)performance within PDE strategies,revealing the interrelationships among them.Finally,the potential future directions and challenges for transitioning from laboratory studies to industrial applications are proposed. 展开更多

Photocatalysis shows promising application in efficient reduction of nitrogen oxides(NOx).However,the sluggish selectivity in nitric oxide removal with reductants,resulting in the formation of undesired N2O byproducts,presents a great challenge.In this work,complete prohibition of nitric oxide generation in photo-removal of NO with carbon particulate is successfully achieved through the rational regulation of electron-trapping centers on TiO2nanosheets(TNS)surface achieved by the surface reduction treatment with NaBH_4.The efficient suppression(100%)of N2O generation is ascribed to the more stable N2O adsorption on the active(001)crystalline plane of TNS and the electron-capturing ability around oxygen vacancies based on the density functional theory(DFT)and experimental investigations.The existence of O2and H2O effectively promote the photocatalytic activity of NO reduction but demonstrate no adverse effect on N2O suppression.The optimal photocatalytic NO reduction activity with the highest CO2formation rate of 5.54 mg g-1h-1without N2O formation is achieved over the optimized 0.135-TNS.These investigations guide the development of feasible photocatalytic treatment of air pollutants,emphasizing the significance of managing electron capture and gas adsorption for efficient byproduct control in pollutants removal. 展开更多

Background:Psoriasis is an immune-driven dermatosis marked by keratinocyte hyperproliferation.GS-9620,a TLR7 agonist,previously mitigated EV71-triggered inflammation in mice;here we probe its anti-psoriatic potential and mechanisms.Methods:IMQ-induced psoriasis-like mice were treated with GS-9620 or MTX;severity was tracked by PASI and histology.Skin/spleen cytokines(IL-1β,IL-6,IL-18,HMGB1,TNF-α)were quantified via ELISA;immune subsets were quantified by flow cytometry.Autophagy proteins(ATG5/12/16 L1)and NLRP3 were assessed by IHC/Western blot.In vitro,M5-stimulated primary keratinocytes were treated with GS-9620±autophagy modulators,followed by cytokine and protein analyses.Results:GS-9620 markedly reduced erythema,scaling and epidermal thickness,lowered skin and systemic cytokines,and decreased splenic CD3+/CD4+IL-17A+cells.It restored ATG5/12/16 L1 expression while suppressing NLRP3 both in lesions and in M5-stimulated keratinocytes,leading to diminished IL-1β,IL-6,IL-18,HMGB1 and TNF-αrelease.Conclusions:GS-9620 alleviates psoriasis by enhancing autophagy and dampening NLRP3-mediated inflammation,offering a promising therapeutic avenue. 展开更多

Genetic variations are risk factors for neonatal hyperbilirubinemia(NHB),a common cause of infant hospitalization in the first postnatal week,but their contribution and long-term impacts remain unclear.This population-based multicenter study enrolls 1780 hospitalized NHB newborns and 38,158 genetically screened newborns across 20 hospitals(2019-2022).Excluding cases with clear clinical causes,977 NHB cases are categorized into genetic variation-positive and-negative groups.Results show significantly higher NHB-related gene variants(81.63%vs.65.62%)and positive variation rates(36.29%vs.9.4%)in NHB cases than in the general newborn population(all P<0.001).Among the 977 NHB cases,325(33.3%)have positive variants,with higher rates of severe hyperbilirubinemia(16.9%vs.9.7%,P=0.001),prolonged jaundice(36.3%vs.27.6%,P=0.005),and cholestasis/hypercholanaemia(23.7%vs.14.7%,P<0.001)in the positive group.Cumulative genetic variants in bilirubin metabolism pathways exhibit dosedependent associations with increased risks of complications.Long-term follow-up reveals that UGT1A1 variants prolong jaundice up to one month,while severe SLC10A1 variants cause persistent cholestasis/hypercholanaemia beyond nine months.This large-scale evidence highlights genetic factors as key NHB determinants,with implications for neonatal care protocols to integrate genetic testing and establish longterm surveillance for variant carriers. 展开更多

Swine enteric coronaviruses(SECoVs)cause severe watery diarrhea and high mortality in piglets,resulting in significant economic losses to the global pig industry.However,frequent mutations in SECoVs significantly compromise vaccine-induced immunity and limit cross-protection against emerging variants.Therefore,there is an urgent need to develop new broad-spectrum antiviral drugs to be the last line of defense to supplement vaccine immunity.In this study,we utilized molecular docking and molecular dynamics simulations to identify phloretin as a broad-spectrum SECoV inhibitor.Phloretin has demonstrated prophylactic and therapeutic efficacy in vitro and in vivo,improving the survival of SECoV-infected piglets.It was further found that phloretin exerts a broad-spectrum antiviral effect by acting on the conserved 3CLpro Cys144 site of three SECoVs.It is worth noting that derivative A12,designed on the basis of the structure-activity relationship(SAR)between phloretin and 3CLpro,showed a 15.7,2.6,and 8.4-fold increase in antiviral effect against porcine epidemic diarrhea virus(PEDV),transmissible gastroenteritis virus(TGEV),and porcine delta coronavirus(PDCoV),respectively.This study reveals a 3CLpro Cys144 targeting broad-spectrum strategy for use against SECoVs,providing a candidate drug to bridge the vaccine immunity gap. 展开更多

Objective:Intratumoral heterogeneity refers to the presence of distinct subpopulations of cancer cells within a single tumor,which exhibits variations in phenotypic traits,such as proliferation rate,drug sensitivity,and metastatic potential.Dynamic interactions among heterogeneous cell populations have a critical role in tumor progression.Increasing evidence underscores the importance of intercellular communication among heterogeneous cancer cell subpopulations in driving malignancy.However,the molecular mechanisms governing such cancer cell-to-cancer cell interactions are poorly understood.Methods:Exosomes were isolated from highly metastatic breast cancer cells(HM-BCCs)and low metastatic breast cancer cells(LM-BCCs).The role of exosome-mediated intercellular communication on metastatic behavior was assessed using wound healing and Transwell assays.Gene knockdown and overexpression strategies,small-molecule inhibitors,and xenograft mouse models were used to elucidate the role of exosomal EPHA2.Results:Exosomes derived from HM-BCCs considerably enhanced the migratory and invasive capabilities of LM-BCCs in vitro and increased the metastatic potential in vivo.Mechanistically,EPHA2 was identified as a key protein enriched in exosomes from HM-BCCs and was shown to be transferred to LM-BCCs by these vesicles.Exosomal EPHA2 promoted epithelial-to-mesenchymal transition in LM-BCCs when internalized by stabilizing TGF-βRI and activating the transforming growth factor-β/mothers against decapentaplegic homolog 3(TGF-β/SMAD3)signaling pathway,thereby facilitating the acquisition of a metastatic phenotype.Conclusions:The results underscore the pivotal function of exosomal EPHA2 in mediating the transfer of metastatic potential among heterogeneous breast cancer cell populations.Targeting the EPHA2-TGF-βRI signaling axis may provide a novel therapeutic approach for preventing or limiting breast cancer metastasis. 展开更多

For Li metal battery,Li metal anodes severely suffer from dendritic growth due to heterogeneous electrodeposition,which inhibits their development and application.While extensive studies for Li dendrite suppression empirically utilize 3D hosts to homogenize the micro-scaled electric field within the host,the inherent correlation between host structure and electric field distribution and underlying principles remains elusive,and the corresponding design of hosts to enhance the electric effects remains challenging.Here,the host microstructure-electric field correlations are established via COMSOL simulations and demonstrate the enhanced redistribution of the electric field through structural redesign of hosts.Based on a structure model,an enhanced gradient electric field host(EGHx)with a supercontinuous gradient pore architecture is fabricated with the assistance of the porogen dissolution method,which achieves a self-leveling-like Li deposition through spatially programmed charge redistribution.Through further structural optimization,the EGH2(with 2 wt%porogen)exhibits an~98%Coulombic efficiency(CE)over 350 cycles(1 mA cm-2,1 mAh cm-2).Further multidimensional testing with argon protection reveals the role of the host in modulating solid-electrolyte interphase(SEI)composition.Accordingly,the EGH2 enables stable dendrite-free Li plating/stripping behaviors for 2100 h.The assembled full cell and pouch cell also display stable cycling performance with an LFP cathode. 展开更多

Superionic conductors with an exceptionally high ionic conductivity are placed central in the development of next-generation energy conversion and storage technologies,yet their designing approach and materials remain a persistent challenge.Here,we report an alternative cation-ordered Ce-Al(1:1)fluorite oxide(ACO)that stabilizes a periodic oxygen vacancy(Ov)network to build the required architecture.The resulting lattice-engineered configuration creates a uniform and flattened potential energy landscape with significantly reduced activation energy,capable of a superionic conductivity of 0.216 S cm⁻¹ and a fuel cell power density of 1086 mW cm⁻² at 500℃.Unlike conventional random ion hopping in doped oxides,the vacancy-ordered framework supports coherent,phonon-assisted and wave-like ion motion enabling dielectric-enhanced superionic conduction.These findings introduce a new family of superionic conductors,where lattice-level ordering of both cations and Ovs offers a scalable design strategy for high-performance efficient electrochemical systems. 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

Solid oxide cells(SOCs)have emerged as one of the key technologies for low-carbon energy transition due to their fuel flexibility and high system efficiency.However,their long-term deployment remains hindered by material degradation and interfacial instability under high-temperature and multi-atmospheric operating conditions.In particular,achieving a balance between catalytic activity and structural stability presents a major bottleneck in material design.High-entropy materials(HEMs),with their unique configurational entropy effect,multi-principal element synergy,and tunable local defect chemistry,offer a promising pathway to overcome these limitations.This perspective reviews recent advances in the application of HEMs in SOCs,including element selection and structure tuning,machine-learning-assisted design,in situ leaching and self-assembly engineering,and high-entropy coating strategies.Special attention is paid to how HEMs leverage their multi-elemental composition and defect regulation to enhance electrode performance,stabilize interfaces,and improve tolerance to poisoning species.We further highlight the potential of data-driven approaches for accelerating HEM screening and performance optimization,and discuss the integration of high-throughput experimentation with computational modeling to enable efficient exploration of the vast compositional space.Despite the remarkable progress,key challenges remain in achieving long-term stability and reliability across diverse operating scenarios.Future research should focus on precise control of non-equimolar compositions,development of cross-scale dynamic characterization techniques,and establishment of closed-loop frameworks that couple data-driven models with experimental feedback.These efforts will pave the way toward the rational design of high-performance,durable SOC systems. 展开更多

Petroleum leakage is a major groundwater contamination source,with chemical composition of water soluble fractions(WSFs)from diverse oil sources significantly impacting groundwater quality and source identification.The aim of this study was to assess impact of 15 diverse oils on groundwater quality and environmental forensics based on oil-water equilibrium experiments.Our results indicate that contamination of groundwater by gasoline and naphtha is primarily attributed to volatile hydrocarbons,while pollution from diesel,kerosene,and crude oil is predominantly from non-hydrocarbons.Rapid determination of the extent of non-hydrocarbon pollution in WSFs was achieved through a new quantitative index.Gasoline and naphtha exhibited the highest groundwater contamination potential while kerosene and light crude oils were also likely to cause groundwater contamina-tion.Although volatile hydrocarbons in the WSFs of diesel and jet fuel do not easily exceed current regulatory standards,unregulated non-hydrocarbons may pose a more severe contamination risk to groundwater.Notably,the presence of significant benzene and toluene,hydrogenation and alkylation products(e.g.,C4-C5 alkylben-zenes,alkylindenes,alkyltetralins,and dihydro-indenes),cycloalkanes in WSFs can effectively be utilized for preliminary source identification of light distillates,middle distillates,and crude oils,respectively. 展开更多
