Nanofiber carbon aerogels with 3D interconnected microfibrillar networks exhibit fascinating physical properties and present great application potential.However,it is still a challenge to fabricate superelastic nanofiber carbon aerogels owing to their extremely dilute brittle interconnections and poor fiber toughness after carbonization.Herein,aramid nanofibers(ANF)anocellulose(CNF)dual-fibrous carbon aerogels are prepared,which exhibited supercompressibility and superelasticity due to the"skeleton-binder"synergistic effect of ANF and CNF and the design of in-plane micro-wrinkle honeycomb structure.The"skeleton-binder"synergistic effect improves interfacial interactions of nanofibers and optimizes the stress distribution of carbon aerogel.The highly ordered honeycomb structure with in-plane microwrinkles,formed by the bidirectional freezing and the difference in volume shrinkage during the carbonization between CNFs and ANFs,endows the CNF/ANF carbon aerogel with negative Poisson's ratio and high energy absorption capacity.These strategies significantly improve the overall mechanical properties of ANF/CNF carbon aerogel including the elasticity and fatigue resistance.As a result,the ultralight carbon aerogel(3.46 mg/cm3)exhibits excellent supercompression(undergoing an extreme strain of 95%)and elasticity(a stress retention up to 81.38% at 90% strain with 500 cycles and 96.15% at 50%strain with 10,000 cycles).The nanofiber carbon aerogel shows excellent multifunctional properties in flexible piezoresistive sensor and anisotropic thermal insulation materials,including a desirable sensitivity(as high as 48.74 kPa-1)and an instant response time(~40 ms),an anisotropy factor of 3.69 and an ultralow radial thermal conductivity(0.012 W m-1 K-1).These properties make dual-fibrous carbon aerogels highly attractive in pressure sensors and thermal management applications. 展开更多

To advance the theoretical understanding,technological development,and field application of electric charge induction for monitoring rock deformation and failure,this study investigates the induced electric charge generated during the deformation and failure of igneous rocks.The charge originates mainly from a combination of electrical polarization and triboelectric effects.Through laboratory experiments,we analyzed the time-frequency evolution of induced electric charge signals and identified relevant monitoring parameters.An online downhole electric charge induction monitoring system was developed and validated in the field.Experimental results show that the dominant frequency range of induced electric charge signals generated during igneous rock deformation and failure lies between 0 and 23 Hz,and a low-pass finite impulse response(FIR)filter effectively suppresses noise.Optimal sensor distances for monitoring cubic and cylindrical specimens were determined to be 17 mm and 13 mm,respectively.We proposed early warning indicators,including the maximum absolute value of the induced electric charge,the arithmetic mean value,the distribution dispersion coefficient,and the cumulative sum value.In field application,time-domain curves and spatial distribution charts of these warning indicators correspond well with changes in abutment stress ahead of the mining face,offering indirect insights into local stress evolution.This research provides technical and equipment support for the application of electric charge induction technology to monitoring and early warning of coal bursts. 展开更多

Monkeypox,a zoonotic illness caused by monkeypox virus(MPXV),has been declared a public health emergency of international concern by the World Health Organization(WHO)on two separate occasions.The rapid spread and widespread transmission are closely associated with various proteins involved in the MPXV lifecycle,particularly surface antigen proteins found in mature virion(MV)and enveloped virion(EV),such as A29L,M1R,B6R,and A35R.These antigens are highly conserved in MPXV and vaccinia virus(VACV),possessing cross-protective capabilities that can trigger broad immune protection against multiple orthopoxviruses,including MPXV.Vaccines based on DNA,mRNA,and recombinant proteins,targeting these antigens effectively address the current lack of specific monkeypox vaccines by triggering strong immune responses and ensuring the prevention of monkeypox.Compared to traditional vaccines,multi-epitope vaccines designed using computational tools such as reverse vaccinology and immunoinformatics offer lower development costs and faster validation processes.These multi-epitope vaccines also provide adaptability to mutations in MPXV strains.Additionally,these antigens and corresponding antibodies are useful for diagnosis and therapeutic monitoring,supporting early detection and offering novel treatments for cases resistant to existing antiviral drugs.This review provides a brief summary of recent progress and emerging trends in monkeypox detection,vaccine development,and antibody-based therapy targeting these antigens,offering new insights for monkeypox prevention and control. 展开更多

The large-scale utilization of renewable energy challenges the stability and safety of the grid;thus,the flexibility of coal-fired power plants should be increased to balance unstable renewable energies.To achieve this,a heat storage system(HSS)is integrated into a power plant.This is the first study utilizing furnace flue gas to drive a molten-salt-heat-exchanger(MSHE).Compared to steam-vapor-driven MSHE,flue gas-driven technology avoids the pinch temperature limitation(PTL)and simplifies the system configuration.In this study,we demonstrate the concept,design,fabrication,and experiments of the MSHE.The novelties include:①finned tubes to balance the thermal resistances between the flue gas side and the molten salt side;②a weak angle design to ensure gravity-driven recession of the molten salt;and③a modular design to ensure even temperature distribution at the outlet of the tube bundles.A heat transfer correlation is developed for molten salt,covering a wide range of Reynolds numbers.An experimental setup is constructed to collect data and verify the effectiveness of the MSHE.The measured overall heat transfer coefficients matched the predictions well,with deviations of less than 10%.The measured heat power reached 320 kW,exceeding the 300 kW design target.We demonstrate the heat transfer between the flue gas and molten salt to compensate for the heat release from the HSS to the environment,reducing electricity consumption in the standby stage of the system.The modular design of the MSHE ensures minimal temperature deviations of<4 K among different tubes,avoiding local overheating-induced decomposition of the molten salt.Based on the 300 kW MSHE results,a 10 MW MSHE is designed,fabricated,and integrated into a 350 megawatt electric(MWe)coal-fired plant to achieve a higher load variation rate of 6%Pe·min-1 for a coal-fired power plant. 展开更多

In the development of coalbed methane(CBM)reservoirs using multistage fractured horizontal wells,there often exist areas that are either repeatedly stimulated or completely unstimulated between fracturing stages,leading to suboptimal reservoir performance.Currently,there is no well-established method for accurately evaluating the effectiveness of such stimulation.This study introduces,for the first time,the concept of the Fracture Network Bridging Coefficient(FNBC)as a novel metric to assess stimulation performance.By quantitatively coupling the proportions of unstimulated and overstimulated volumes,the FNBC effectively characterizes the connectivity and efficiency of the fracture network.A background grid calibration method is developed to quantify the stage-controlled volume,effectively stimulated volume,unstimulated volume,and repeatedly stimulated volume among different stages of horizontal wells.Furthermore,an optimization model is constructed by taking the FNBC as the objective function and the fracturing injection rate and fluid volume as optimization variables.The Simultaneous Perturbation Stochastic Approximation(SPSA)algorithm is employed to iteratively perturb and optimize these variables,progressively improving the FNBC until the optimal displacement rate and fluid volume corresponding to the maximum FNBC are obtained.Field application in a typical CBM multistage fractured horizontal well in China demonstrates that the FNBC increased from 0.358 to 0.539(a 50.6% improvement),with the injection rate rising from 16 m3/min to 24 m3/min and the average fluid volume per stage increasing from 2490 m3 to 3192 m3,significantly enhancing the stimulation effectiveness.This research provides theoretical support for designing high-efficiency stimulation strategies in unconventional reservoirs under dynamic limits. 展开更多

Nonhuman primates are increasingly being used as animal models in neuroscience research.However,efficient neuronal tracing techniques for labeling motor neurons and primary sensory afferents in the monkey spinal cord are lacking.Here,by injecting the cholera toxin B subunit into the sciatic nerve of a rhesus monkey,we successfully labeled the motor neurons and primary sensory afferents in the lumbar and sacralspinal cord.Labeled alpha motor neurons were located in lamina IX of the L6–S1 segments,which innervate both flexors and extensors.The labeled primary sensory afferents were mainly myelinated Aβfibers that terminated mostly in laminae I and II of the L4–L7 segments.Together with the labeled proprioceptive afferents,the primary sensory afferents formed excitatory synapses with multiple types of spinal neurons.In summary,our methods successfully traced neuronal connections in the monkey spinal cord and can be used in spinal cord studies when nonhuman primates are used. 展开更多

Understanding the molecular responses of tea leaves to mechanical stress is crucial for elucidating the mechanisms of post-harvest quality formation during oolong tea processing.This study employed an integrated multi-omics strategy to characterize the changes and interactions among metabolomic(MB),transcriptomic(TX),and proteomic(PT)profiles in mechanically stressed tea leaves.Mechanical stress initially activated damage-associated molecular patterns(DAMPs),including Ca2+signaling,jasmonic acid signaling,and glutathione metabolism pathways.These processes subsequently induced quality-related metabolic pathways(QRMPs),particularly α-linolenic acid and phenylalanine metabolism.Upregulated expression of LOX,ADH1,and PAR genes,together with the increased abundance of their encoded proteins,respectively promoted the accumulation of jasmine lactone,benzyl alcohol,and 2-phenylethanol.These findings indicate that mechanical stress influences the metabolite biosynthesis in tea leaves through coordinated molecular responses.This study provides new insights into the molecular mechanisms underlying tea leaf responses to mechanical stress and a foundation for future investigations into how early molecular events may contribute to post-harvest metabolic changes during oolong tea processing. 展开更多

Osteoporosis,the most prevalent skeletal disorder,is primarily driven by aberrantly increased osteoclast formation and/or activity.Targeting hyperactive osteoclasts remains the cornerstone of current therapeutic strategies.Crebanine(Cre),a natural isoquinoline-derived alkaloid with diverse pharmacological activities,has not yet been explored for osteoporosis treatment.This study aimed to evaluate the therapeutic potential of Cre against ovariectomy(OVX)-induced osteoporosis and elucidate its underlying mechanisms.Cre dose-dependently inhibited in vitro osteoclast differentiation,actin ring formation,and bone resorption by downregulating nuclear factor of activated T cells 1(NFATc1)and key osteoclast-related genes.Simultaneously,Cre enhanced osteoblast differentiation and mineralization,upregulated osteoblast marker genes,and restored hydrogen peroxide-impaired alkaline phosphatase(ALP)activity impaired by hydrogen peroxide,indicating dual regulation of bone remodeling.Mechanistically,Cre activated sirtuin 1(Sirt1),promoting p65 deacetylation,inactivated IκB kinase(IKK),and stabilized IκBα,thus inhibiting nuclear factor-kappaB(NF-κB)signaling.Additionally,Cre reduced reactive oxygen species(ROS)by upregulating antioxidant enzymes(heme oxygenase-1(HO-1),catalase)and suppressing nicotinamide adenine dinucleotide(NAD)phosphate(NADPH)oxidases(NOX1/4).Furthermore,Cre specifically bound to the predicted site of receptor activator of NF-κB(RANK),blocking RANK ligand(RANKL)-RANK interaction and disrupting downstream protein kinase B(Akt)and mitogen-activated protein kinase(MAPK)signaling pathways.In the OVX mouse model,Cre significantly attenuated bone loss and osteoclastogenesis.Crucially,Cre showed no toxicity in liver or kidney function tests.Collectively,these findings demonstrate that Cre exerts dual therapeutic effects,inhibiting osteoclastogenesis via Sirt1-mediated NF-κB/ROS suppression and promoting osteoblast activity,providing a promising therapeutic strategy for osteoporosis. 展开更多

Background Fatty liver syndrome is a prevalent metabolic disorder in transition dairy cows,characterized by excessive hepatic lipid accumulation that impairs liver function and leads to systemic metabolic disturbances.Docosahexaenoic acid(DHA),a prominent n-3 polyunsaturated fatty acid(PUFA),not only exhibits anti-inflammatory and anti-oxidative properties,but also holds potential in ameliorating lipid metabolism.This study integrated in vitro bovine primary hepatocyte models and in vivo dairy cow trials to investigate the regulatory effects of DHA on hepatic lipid deposition.Results In vitro,40μmol/L DHA significantly reduced triglyceride(TAG)accumulation in steatotic hepatocytes by downregulating genes involved in fatty acid transport(FABP-1,CD36)and lipogenesis(DGAT2,FAS,SREBP-1C),while upregulating markers of lipolysis(CGI-58,ATGL)and fatty acid oxidation(ACADL,CPT1A,CPT2).Transmission electron microscopy(TEM)confirmed DHA-mediated restoration of mitochondrial ultrastructure and enhanced lipid droplet(LD)-mitochondria interactions.In vivo,dietary rumen-protected DHA(180 g/d)supplementation reduced hepatic lipid deposition,improved liver function(evidenced by decreased total bilirubin and alanine aminotransferase),reduced oxidative stress and inflammation(suppressed malondialdehyde,glutathione peroxidase,and lipopolysaccharide),coincided with relieving insulin resistance(reduced insulin and glucose,as well increased adiponectin)in dairy cows with fatty liver.These improvements may be attributed to increased expression of TOMM20 and MtCo-1,promoting mitochondrial biogenesis andβ-oxidation,along with an elevated plasma n-3-6 ratio.Conclusions Collectively,these findings suggest that DHA supplementation represents a promising nutritional strategy for preventing spontaneous fatty liver in transition dairy cows by enhancing hepatic lipid clearance and restoring metabolic homeostasis. 展开更多

As an emerging biomarker,tumor mutational burden(TMB)has attracted increasing attention from clinicians in predicting the efficacy of tumor immunotherapy.Currently,TMB is detected primarily by whole-exome sequencing or targeted panel sequencing on high-throughput sequencing platforms.However,the lack of uniformity in detection methods,threshold settings,and reporting formats,as well as the significant differences in TMB values among different cancer types,have hindered the standardized application of this biomarker in clinical practice.This consensus focuses on the definition,standardization of detection,clinical significance,and limitations of TMB,and provides consensus recommendations for the clinical application of TMB in real-world practice in China.This consensus is aimed at helping clinicians and laboratory personnel understand the clinical significance and testing standards of TMB,promoting more accurate interpretation of test results,and improving patient care. 展开更多

The Late Paleozoic tectonic evolution of the Junggar Basin played a critical role in the formation of its oil and gas resources;however,as most of the basin is covered by desert,the evolutionary process remains controversial.In this study,we present a comprehensive analysis of the rock associations,petrography,ages,and systematic elemental and isotopic compositions of Carboniferous volcanic rocks obtained from drilling holes along the western margin of the basin,aiming to better constrain the late Paleozoic tectonic evolution of this region.Two zircon samples,from tuff and andesite layers,yielded concordant ages of 316.8±1.7 and 321.7±1.8 Ma,respectively,indicating intense volcanic eruptions during the Late Carboniferous.The analyzed volcanic rocks exhibited sodic calc-alkaline affinities,with SiO2content ranging from 53.46 to 61.57 wt%,TiO2content from 0.75 to 1.20 wt%,and a significantly higher Na2O content than that of K2O.In terms of trace elements,they showed variable enrichment in light rare earth elements((La/Yb)N=2.72 to 7.89)and large ion lithophile elements such as Ba,Th,U,and Sr.Low Cr(0.67-65.72)and Ni(0.86-34.90)contents,together with significant negative Eu anomalies(δEu=0.17 to 0.35),suggest variable fractionation of the primitive magma prior to eruption.All these features,combined with prominent Nb-Ta depletions in PM-normalized incompatible element spider diagrams,unambiguously indicate their genetic relationship with a subduction environment.However,the volcanic rocks showed low initial(87Sr/86Sr)i values(0.7039-0.7057)and positiveεNd(t)values(7.5-8.0).Moreover,the combined(208Pb/204Pb)i ranged from 37.7295 to 37.7851,(207Pb/204Pb)i ranged from15.4935 to 15.5037,and(206Pb/204Pb)i ranged from 17.8910 to 17.9254,indicating that their primitive magma originated from an extremely depleted mantle source with crustal contamination.Integrating this study with regional geology,we propose that the volcanic rocks in the Kebai Fault Zone were most likely formed in a back-arc basin setting induced by ridge subduction. 展开更多

To address the critical gaps in modeling the failure of gas-bearing coal under realistic multi-source disturbances,this study developed,for the first time,a systematically integrated dual-disturbance damage mechanics model.The model uniquely synthesizes a modified Nishihara-NVPB creep framework with partitioned damage evolution laws to concurrently account for gas adsorption,long-term axial static stress,and the synergistic effects of superimposed cyclic and impact dynamic loads.The core innovation is this strategic damage-partitioning integration,where damage from gas and static load is embedded into the elastic element,and damage from dynamic disturbances is embedded into the viscous and plastic elements,enabling a unified representation of complex multi-factor coupling.This integrated constitutive model was successfully embedded into the GDEM continuum-discontinuum software.A full engineering-scale numerical simulation of a coal and gas outburst was conducted.The results,including the excavation outburst initiation distance,in-situ stress evolution at monitoring points,and outburst coal volume,showed high consistency with benchmark results from a large-scale physical simulation test.This work verifies the model's reliability and applicability at the engineering scale and provides a novel analytical framework and computational tool for investigating the disaster mechanisms of coal and rock dynamic disasters under dual disturbances. 展开更多

Dolichopetalum is a monotypic liana genus of Apocynaceae and is restricted to subtropical montane forests in Asian subtropical karst areas.In this study,we used plastome data to examine the tribal position of Dolichopetalum within the family,and four plastid and three nuclear loci to further clarify its relationship and taxonomic status.We also estimated the time of origin of Dolichopetalum and modeled its range change by estimating the potential historic and current distributions.Our family-wide phylogenetic analysis confirms that Dolichopetalum belongs to the tribe Marsdenieae.Our subsequent analyses of Marsdenieae further suggest that Dolichopetalum is a distinct genus and has a distant relationship with Marsdenia s.str.,challenging the traditional viewpoint.Dolichopetalum is probably allied to Campestigma,Cionura,Harmandiella,and Gongronema-Dischidanthus-Sarcolobus,and originated at about 11 Ma and rapidly diverged with its four allies over a period of less than three million years,which might be associated with the intensified East Asian monsoon in the early Late Miocene.The distributional range of Dolichopetalum may have undergone a dramatic contraction since the Last Glacial Maximum and will likely further shrink and undergo fragmentation in the future,possibly driven by global warming and desertification in Asian subtropical karst areas.This study provides new insights into the evolutionary history of Dolichopetalum and will have important conservation implications for the unique biodiversity of Asian subtropical karst areas under climate change scenarios. 展开更多

Ammonia-oxidizing bacteria(AOB)are slow-growing autotrophs prone to washout.Biofilm carriers improve retention;however,conventional types suffer from low roughness,poor hydrophilicity,and unfavorable surface charge,limiting biofilm formation.In this study,a composite carrier was fabricated by loading chitosan(CS)and layered double hydroxide(LDH)onto a polyurethane(PU)sponge,which introduced hydroxyl(-OH)and amino(-NH2)functional groups as well as Mg2+and Al3+ions onto the surface,increased surface roughness,and enhanced the carrier hydrophilicity by 29.2%.During a 55-d nitritation biofilm cultivation experiment,the carrier modified with 0.8 wt%LDH and 0.8 wt%chitosan exhibited significantly enhanced performance.Compared to the unmodified carrier,the sludge adsorption capacity increased by 80.3%,the biofilm biomass increased by 46.8%,and the biofilm growth rate increased by 198.3%,reaching 333.4±9.5 mg/carrier,2023.2±31.5 mg/carrier,and 103.2 mg/(carrier·d)respectively.In addition,the biofilm stability on the carrier was significantly enhanced,with a 54.1%reduction in sludge detachment under ultrasound treatment compared with the unmodified carrier.The nitritation reactor with the CS/LDH-PU carrier maintained stable nitritation performance under high ammonia loading(1.0 g/(L·d))and a higher sludge concentration(5.5 g/L),while the reactor without the carrier collapsed at a lower sludge concentration(4.6 g/L).These findings suggest that the CS/LDH-PU carrier provides an effective strategy for optimizing conventional nitritation carriers and enhancing the resilience of nitritation systems under high ammonia load conditions. 展开更多
