Artificial humic acid(AHA)is a new exogenous organic material with enormous carbon(C)sequestration potential.However,the effects of applying AHA under different irrigation regimes on C sequestration in the rice-soil system and the underlying mechanisms still need to be clarified.This study employed C isotope labeling technology to analyze the photosynthetic C sequestration capacity,C transport capacity of rice roots,and greenhouse gas emission flux in the rice-soil system under different irrigation regimes and AHA application conditions.The results showed that as the amount of AHA application increased,the leaf area and chlorophyll concentration gradually increased,and the ribulose-1,5-bisphosphate carboxylase/oxygenase(Rubisco)activity first increased and then decreased under two irrigation regimes(conventional flooding and alternate wetting and drying irrigation).In the alternate wetting and drying irrigation with 300 mg kg-1AHA application treatment(DWI3),the photosynthetic C fixation was the highest,with the net photosynthetic rate increasing by 65.35% compared to the alternate wetting and drying irrigation without applying AHA treatment(DWI0).Meanwhile,the organic acid concentration in root exudates,biomass,length,surface area,and length density were also the highest in the DWI3 treatment.Besides,the content of~(13)C in soil was the highest in the DWI3 treatment,closely related to the strongest photosynthetic C fixation and root transport capacity,as well as the lowest greenhouse gas emission flux.Therefore,it is recommended to apply 300 mg kg-1AHA with alternate wetting and drying irrigation for C sequestration,water conservation,and sustainable agricultural development. 展开更多

Ln@MOFs by anchoring rare metal ions(Ln) into metal-organic frameworks(MOFs) are proved to have great potential in the field of luminescent molecular thermometer.Nevertheless,the current research indicated that the poor structural stability and low sensitivity hindered their application scope.In this work,a new MOF Zn-450 luminescent thermometer with multiple emission fluorescence characteristics was synthesized by the combination of 3,3,5,5-biphenyl tetracarboxylic acid(H4L) and Zn2+ ion under solvothermal conditions.Interestingly,a high relative sensitivity of 1.43 % K-1 was found within 80-300 K based on Zn-450.Subsequently,two high-sensitivity luminescent Ln@MOFs(Ln = Eu and Tb) were further fabricated by doping rare earth ions into Zn-450 based on the post-synthesis strategy.Among them,the Eu@Zn-450 demonstrates various luminous behaviors while achieving an increased relative sensitivity of 1.63 % K-1.In addition,the continuously visible red,pink,and purple luminescent emissions at the same temperature range were observed,suggesting that the Eu@Zn-450 could be utilized as a luminescent colorimetric molecular thermometer.Importantly,this work can present new possibilities for the development of rare earth-doped luminescence and its temperature sensing properties. 展开更多

Efficient surface passivation is critical for achieving high-performance perovskite solar cells(PSCs),yet the discovery of optimal passivators remains a time-consuming,trial-and-error process.Here,we report a synergistic machine learning(ML)and density functional theory(DFT)approach that enables predictive and rapid identification of effective passivation materials.By training an XGBoost model(91.3%accuracy)with DFT-derived molecular descriptors and activity calculations,we identify 2-(4-aminophenyl)-3H-benzimidazol-5-amine(APBIA)as a promising passivator.Experimental validation demonstrates that APBIA effectively removes surface impurities and passivates defects within perovskite films,leading to a significant increase in power conversion efficiency(PCE)from 22.48%to 25.55%(certified as 25.02%).This ML-DFT framework provides a generalizable pathway for accelerating the development of advanced functional materials for photovoltaic applications. 展开更多

A 2D/3D switchable display based on the polarization-multiplexed metasurface is proposed.The designed metasurface is governed by the Pancharatnam-Berry(PB)phase,which performs the functionality of either a lens for 2D display or a 4×4 lens array for 3D integral imaging(3D-II)display under different circularly polarized light illumination.As a proof of concept,a metallic metasurface on a SiO2 substrate is fabricated,and its lens and lens array operations are experimentally validated by focusing characterization.Using a commercial OLED panel as the light source in the experimental setup,we demonstrate a polarization-controlled display prototype capable of switching between high-resolution 2D images and full-parallax 3D scenes.The simulated and experimental results confirm the 2D/3D switching functionality of the proposed approach,offering promising potential for applications in floating,virtual reality/augmented reality,portable,and wearable display devices. 展开更多

This paper describes the design and performance of the tender energy spectroscopy beamline(BL16U1),a phase Ⅱ beamline,at the Shanghai Synchrotron Radiation Facility.The beamline,based on an in-vacuum undulator source with 26 mm period,provides an operable energy range between 2.1 keV and 16 keV,covering the K-edges of P to Rb and L3-edges of Zr to Bi.The principal optical elements of the beamline are a toroidal mirror,a liquid nitrogen-cooled double-crystal monochromator,a high-harmonic-rejection mirror,and two pairs of Kirkpatrick–Baez(KB)mirrors.Three end-stations,including non-focusing,microprobe,and sub-microprobe types,are installed on the beamline.X-ray fluorescence(XRF)and X-ray absorption spectroscopy(XAS),including X-ray absorption near-edge structure(XANES)and extended X-ray absorption fine structure(EXAFS),are performed under vacuum or He atmosphere at the non-focusing end-station(with a beam spot size of∼670μm×710μm).Using two KB mirrors systems,micro-XRF(μXRF)mapping and micro-XANES(μXANES)studies can be performed with a spot size of approximately∼3.3μm×1.3μm at the microprobe end-station and with a smaller spot size of∼0.5μm×0.25μm at the sub-microprobe end-station.The non-focusing end-station was officially opened to users in January 2024.The microprobe and sub-microprobe end-stations will be opened to users in the near future.This paper presents the characteristics,short-term technical developments,and early experimental results of this new beamline. 展开更多

Soil compaction often imposes stress on root development and plant survival.However,root anatomical responses that enable persistent root growth and functioning under soil compaction remain unclear.We grew 10 herbaceous species differing substantially in lateral root diameter,in soils with low(1.0 g cm-3)and high(1.4 g cm-3)bulk density,and assessed root traits including root biomass,anatomical structures,and respiration rates.Greater root thickening upon soil compaction was found in species with thicker first-order lateral roots,mainly due to larger cortical cell size.Both xylem vessel diameter and wall thickness increased more in compacted soils in these species.Despite these anatomical shifts,root respiration rate responded little to soil compaction across most species,likely due to the opposite investment in cortical cells and xylem vessels.Notably,root biomass,independent of root respiration rate and anatomical structures,determined whole-plant growth under soil compaction.Our study reveals two independent strategies of root response to soil compaction:anatomical remodeling for mechanical and metabolic maintenance,and root biomass investment for resource acquisition.These findings offer new insights for breeding and selecting species tolerant to soil compaction and highlight multidimensional strategies of plant adaptation to physical stress. 展开更多

Breeding resistant wheat(Triticum aestivum)cultivars is the most efficient way to manage wheat stripe rust,a highly destructive disease caused by the fungal pathogen Puccinia striiformis f.sp.tritici(Pst).Therefore,the exploration of new resistance genes is ongoing.The resistance gene Yr85 confers protection against predominant Pst races in China at all stages of plant development.Here,we fine-mapped Yr85 to a 0.12 cM interval between allele-specific quantitative PCR markers XK1B-61 and XK1B-65,corresponding to a 1.76 Mb region on chromosome 1BS in the IWGSC RefSeq v2.1 reference genome(wheat cultivar Chinese Spring),using 5507 F5 plants derived from heterozygous F4 plants,themselves descendants of an AvS×AvSYr85NIL cross.Haplotype analysis and whole-genome resequencing suggested that Yr85may be from a distant source.Moreover,agronomic trait evaluation indicated that Yr85 is located in a chromosomal region lacking linkage drag.Genotyping of 309 Chinese wheat cultivars and lines with a marker that cosegregated with Yr85 during fine mapping identified one cultivar possibly carrying the resistance gene.Our findings indicate that Yr85 has potential for use in wheat-breeding programs in China.This study lays the foundation for map-based cloning and marker-assisted selection of Yr85. 展开更多

BACKGROUND There are few drugs available for the third-line treatment of metastatic colorectal cancer(mCRC),and efficacy is generally poor.Fruquintinib,an anti-vascular endothelial growth factor receptor tyrosine kinase inhibitor,has been approved for mCRC;however,its efficacy as a single agent is not satisfactory.Most patients with mCRC are microsatellite stable(MSS),and not sensitive to immunotherapy.The combination of fruquintinib and immunotherapy may improve the survival of patients with mCRC.AIM To report the real-world experience using this combination therapy for MSS mCRC in routine clinical practice.METHODS The medical records of six patients with MSS mCRC who received third-line treatment with fruquintinib plus sintilimab between January 2022 and June 2024 were retrospectively reviewed.Survival analysis was performed using the Kaplan-Meier method.RESULTS One patient achieved a complete response,one had stable disease,and four experienced progressive disease.Median progression-free survival was 3.8 months,and median overall survival was 5.7 months.Common adverse reactions included bone marrow suppression,liver function impairment,and hypothyroidism,predominantly grades 1-2,with no grade 4 adverse reactions reported.CONCLUSION Our single-center experience in a small cohort implies fruquintinib combined with sintilimab may be efficacious and safe for select patients in the third-line treatment of mCRC.This combination therapy warrants further exploration. 展开更多

Brittleness is a bottleneck hindering the applications of fruitful functional properties of Ni–Mn-based multiferroic alloys.Recently,experimental studies on B alloying shed new light on this issue.However,the knowledge related to B alloying is limited until now.More importantly,the mechanism of the improved ductility,which is intrinsically related to the chemical bond that is difficult to reveal by routine experiments,is still unclear.In this context,by first-principles calculations,the impact and the correlated mechanism of B alloying were systemically studied by investigating four alloying systems,i.e.,(Ni2-xBx)MnGa,Ni2(Mn1-xBx)Ga,Ni2Mn(Ga1-xBx)and(Ni2MnGa)1-xBx.Results show that B prefers the direct occupation manner when it replaces Ni,Mn and Ga.For interstitial doping,B tends to locate at octahedral rather than tetrahedral interstice.Calculations show that the replacement of B for Ga can effectively improve(reduce)the inherent ductility(inherent strength)due to the weaker covalent strength of Ni(Mn)–B compared with Ni(Mn)–Ga.In contrast,B staying at octahedral interstice will lead to the formation of new chemical bonds between Ni(Mn)and B,bringing about a significantly improved strength and a greatly reduced ductility.Upon the substitutions for Ni and Mn,they affect both the inherent ductility and strength insignificantly.For phase transition,the replacement of B for Ga tends to destabilize the austenite,which can be understood in the picture of the band Jahn–Teller effect.Besides,the substitution for Ga would not lead to an obvious reduction of magnetization. 展开更多

Significant progress has been recently made in studying artemisinin and its derivatives for treating cardiovascular diseases,making this area a prominent research focus.Artemisinin,discovered with great acclaim,was initially and widely adopted in antimalarial treatments.As scientific research steadily progressed,its latent potential role in the cardiovascular system gradually captured the attention of the global scientific community.Artemisinin and its derivatives can reportedly play a protective role in the cardiovascular system through various mechanisms,including anti-inflammatory,anti-angiogenic,antioxidant,and anti-fibrotic effects,as well as the regulation of blood lipids and blood pressure.In particular,they have shown promising therapeutic effects in models of cardiovascular diseases such as atherosclerosis,myocardial ischaemia,and cardiac hypertrophy.In addition,artemisinin and its derivatives can improve cardiovascular function and prevent cardiovascular injury by regulating signalling pathways closely related to cardiovascular disease,such as AMPK and NF-kB.Although numerous ex vivo and in vivo experiments have verified the potential role of artemisinin in treating cardiovascular diseases,systematic studies to comprehensively elucidate its specific mechanism of action remain scarce.Further exploration of the precise roles of artemisinin and its derivatives in cardiovascular disease therapy,along with their potential clinical applications,could offer valuable insights for future research and treatment strategies. 展开更多

Inorganic perovskite solar cells(IPSCs),due to their suitable bandgap and superior thermal stability,are ideal candidates for tandem solar cells combined with silicon.However,the development of inorganic perovskite solar cells has been hindered by suboptimal crystallization dynamics that generate detrimental defects in the perovskite lattice.Here,we propose 4-Methoxyphenylphosphonic Acid(4MPA)as a multifunctional additive to address this challenge.P=O in 4MPA establish strong coordination with undercoordinated Pb2+,while-OH engage in O...H-O hydrogen bonding interactions with DMSO,effectively weakening the solvent-[PbX6]4-octahedron interaction.This dual functionality facilitates complete and rapid DMA+-to-Cs+cation exchange while regulating crystallization kinetics,thereby optimizing crystal growth.Furthermore,π-π interactions between benzene rings significantly enhance the moisture resistance of the perovskite layer.The optimized device demonstrates a power conversion efficiency(PCE)of 21.35%,with unencapsulated devices retaining 93,63%of their initial efficiency after 200-hour continuous operation under ambient conditions(35%relative humidity). 展开更多

The construction of tunnels inevitably leads to ground subsidence,while surface collapses caused by caverns during excavation can result in significant financial losses.However,previous research on tunnel excavation behavior in karst areas has predominantly assumed uniform soil strength,neglecting the geological uncertainty arising from soil spatial variability and rarely discussing the combined effects of soil variability and geological construction conditions.Therefore,this study conducted a series of random finite element analyses to investigate ground subsidence during tunnel excavation in karst cave areas,considering the combined effects of different karst cave distances and sizes as well as soil spatial variability.It was found that shorter distances between the cavern and the tunnel resulted in greater shifts in subsided trench toward the sides of the cavern.Furthermore,larger cavern diameters amplified the effect of geological variability on soils,leading to increased dispersion of maximum ground subsidence.Ground subsistence also showed sensitivity to changes in soil modulus with the coefficient of variation(COV).Neglecting cave influences could potentially underestimate failure probabilities.Additionally,three patterns for surface subsidence were presented based on different geological conditions.Finally,this study proposed a modified Peck formula to predict ground subsidence during tunnel excavation considering the combined effects of karst cave and soil spatial variability,which may enhance current design methods for tunnel engineering. 展开更多

The accumulation of soil organic carbon(SOC)and total nitrogen(TN)is easily accomplished by returning crop straw,which strongly affects the formation and pore structure of aggregates,especially in black soil.We returned maize straw at different rates(6,000,9,000,12,000 and 15,000 kg ha-1)for nine years to investigate its influence on the SOC and TN contents in the SOC fractions of aggregates by combining size and density fractionation.Their subsequent influences on pore morphology and size distribution characteristics were examined using X-ray microcomputed tomography scanning(μCT).The results showed that returning straw significantly increased the contents of C and N in the SOC fractions of aggregates,especially at the return rates of 12,000 and 15,000 kg ha-1,which in turn promoted aggregate formation and stability,and ultimately amended pore structure.The pore size>100μm,porosity(>2μm),and morphological characteristics(anisotropy,circularity,connectivity and fractal dimension)significantly increased,but the total number of pores significantly decreased(P<0.05).Our results indicated that the amendment of the pore morphology and size distribution of soil aggregates was primarily controlled by the higher contents of C and N in the density fractions of aggregates,rather than in the aggregate sizes.Furthermore,this pore network reconfiguration favored the storage of C and N simultaneously.The findings of this study offer valuable new insights into the relationships between C and N storage and the pore characteristics in soil aggregates under straw return. 展开更多

The self-assembly and photothermal application studies of interlocked compounds has been attracting increasing attention during the last decades.Nevertheless,the synthesis of a series of interlocked topologies possessing similar structural characteristic and clarifying their photothermal performance law remains a challenge.Herein,we introduce a new dipyridinyl ligand L1 featuring two methoxy groups,which act as electron-donating species and provide electrons to the central benzene ring,resulting in an enhanced electron rich effect.Previous research indicates that this feature significantly contributes to forming π-stacking interactions.Furthermore,four half-sandwich rhodium-based building blocks exhibiting different metal-to-metal distances and conjugated effect were selected and used to combine with L1 for the synthesis of[2]catenanes and metallamacrocycles for studying the influence of half-sandwich building blocks on photothermal conversion performance under the same accumulation effect.Three new metalla[2]catenanes and one metallamacrocycle have been obtained in high yields and their structure has been unambiguously confirmed by single crystal X-ray diffraction analysis,NMR spectroscopy,and ESI-TOF-MS.In addition,dynamic structural transformation between[2]catenanes and the corresponding metallamacrocycles has been observed through concentration changes and polar solvent induced effect.Photothermal conversion abilities of the isolated complexes were studied and we observed that[2]catenane 3a displayed significant temperature changes(from 25.8℃ to 50.3℃)under laser irradiation of 1.5 W/cm2,thereby reaching a photothermal conversion efficiency of 40.42%.Recorded EPR data indicates that the synergistic cooperation of the free radical effect at the building unit and the stacking effect of[2]catenanes most likely generated photothermal conversion. 展开更多

Background:The aim was to explore the effect of macrophage polarization and macrophage-to-myofibroblast transition(MMT)in silicosis.Methods:Male Wistar rats were divided into a control group and a silicosis group developed using a HOPE MED 8050 dynamic automatic dusting system.Murine mac-rophage MH-S cells were randomly divided into a control group and an SiO2 group.The pathological changes in lung tissue were observed using hematoxylin and eosin(HE)and Van Gieson(VG)staining.The distribution and location of macrophage marker(F4/80),M1 macrophage marker(iNOS),M2 macrophage marker(CD206),and myofibroblast marker(α-smooth muscle actin[α-SMA])were detected using immu-nohistochemical and immunofluorescent staining.The expression changes in iNOS,Arg,α-SMA,vimentin,and type I collagen(Col I)were measured using Western blot.Results:The results of HE and VG staining showed obvious silicon nodule formation and the distribution of thick collagen fibers in the lung tissue of the silicosis group.Macrophage marker F4/80 increased gradually from 8 to 32 weeks after exposure to silica.Immunohistochemical and immunofluorescent staining results revealed that there were more iNOS-positive cells and some CD206-positive cells in the lung tissue of the silicosis group at 8 weeks.More CD206-positive cells were found in the silicon nodules of the lung tissues in the silicosis group at 32 weeks.Western blot analysis showed that the expressions of Inducible nitric oxide synthase and Arg protein in the lung tissues of the silicosis group were upregulated compared with those of the con-trol group.The results of immunofluorescence staining showed the co-expression of F4/80,α-SMA,and Col I,and CD206 andα-SMA were co-expressed in the lung tissue of the silicosis group.The extracted rat alveolar lavage fluid revealed F4/80+α-SMA+,CD206+α-SMA+,and F4/80+α-SMA+Col I+cells using immunofluorescence staining.Similar results were also found in MH-S cells induced by SiO2.Conclusions:The development of silicosis is accompanied by macrophage polarization and MMT. 展开更多

The tensile strain in inorganic perovskite films induced by thermal annealing is one of the primary factors contributing to the inefficiency and instability of inorganic perovskite solar cells(IPSCs),which reduces the defect formation energy.Here,a flexible molecule 5-maleimidovaleric acid(5-MVA)was introduced as a strain buffer to release the residual strain of CsPbI2.85Br0.15perovskite.Maleic anhydride and carboxyl groups in 5-MVA interact strongly with the uncoordinated Pb2+through Lewis acid-base reaction,thus tightly“pull”the perovskite lattice.The in-between soft carbon chain increased the structural flexibility of CsPbI2.85Br0.15perovskite materials,which effectively relieved the intrinsic internal strain of CsPbI2.85Br0.15,resisted the corrosion of external strain,and also reduced the formation of defects such as VIand Pb0.In addition,the introduction of 5-MVA improved crystal quality,passivated residual defects,and narrowed energy level barriers.Eventually,power conversion efficiency(PCE)of NiOxbased inverted IPSCs increased from 19.25%to 20.82%with the open-circuit voltage enhanced from 1.164 V to 1.230 V.The release of strain also improved the stability of CsPbI2.85Br0.15perovskite films and devices. 展开更多

Malate dehydrogenase(MDH)is a widely expressed enzyme that plays a key role in plant growth,development,and stress responses.However,information on MDH genes in the soybean genome is limited.Seventeen members of the soybean MDH family were identified by genome-wide analysis,and the genes were analyzed for the presence of conserved protein motifs.The genes were divided into five clusters according to their phylogenetic relationships.The intracellular localizations of six GmMDHs were determined by confocal microscopy of Arabidopsis mesophyll protoplasts.Transcripts of GmMDHs were significantly increased by abiotic stress(drought,salt,and alkalinity)and hormone treatments,as shown by an analysis of cis-regulatory elements and quantitative real-time polymerase chain reaction(qRT-PCR).The GmMDHs displayed unique expression patterns in various soybean tissues.Notably,the expression levels of a chloroplast isoform(GmMDH2)were unusually high under salt stress,presumably indicating a critical role in soybean responses to salinity.Expression of GmMDH2 in Escherichia coli showed that the recombinant enzyme has nicotinamide adenine dinucleotide phosphate(NADP)-dependent MDH activity.The redox states of the NADP(reduced form)(NADPH)pool and antioxidant activities were shown to be modulated by GmMDH2 gene overexpression,which in turn reduced reactive oxygen species(ROS)formation in transgenic soybean,significantly enhancing the salt stress resistance.Gene-based association analysis showed that variations in GmMDH2 were strongly linked to seedling salt tolerance.A polymorphism potentially associated with salt tolerance was discovered in the promoter region of GmMDH2.These findings not only improve our understanding of the stress response mechanism by identifying and characterizing the MDH gene family throughout the soybean genome but they also identified a potential candidate gene for the future enhancement of salt tolerance in soybean. 展开更多

BACKGROUND Primary gastrointestinal diffuse large B-cell lymphoma(PGI-DLBCL),the most prevalent extranodal non-Hodgkin lymphoma,poses significant diagnostic and therapeutic challenges due to its non-specific symptoms and poor prognosis.AIM To develop and validate a risk model for the early identification of PGI-DLBCL using Least Absolute Shrinkage and Selection-Cox regression,with the aim of guiding clinical decision-making.METHODS The clinical data of patients diagnosed with PGI-DLBCL at the Tumor Hospital Affiliated to Xinjiang Medical University were analyzed retrospectively from January 2010 to April 2022.RESULTS A total of 319 patients with PGI-DLBCL were included and divided into training(n=223)and validation(n=96)cohorts.The median age was 55 years,with 48.9%male and 51.1%female patients.Key clinical features included Eastern Cooperative Oncology Group performance status≥2(40.8%),advanced-stage disease(stage IV:27.6%),extranodal involvement≥2 sites(47%),tumor>5 cm(46.1%),elevated beta-2 microglobulin(50.5%),elevated lactate dehydrogenase(27%),high International Prognostic Index(3-5:69.9%),non-germinal center B-cell-like subtype(59.9%),and B symptoms(55.8%).Immunohistochemical analysis showed frequent expression of CD10(51.1%),B-cell lymphoma 6(53.3%),multiple myeloma oncogene 1(40.1%),Bcell lymphoma 2(49.2%),myelocytomatosis viral oncogene homolog(48.3%),Ki-67(67.1%),and CD5(42.6%);Epstein-Barr virus-encoded RNA was positive in 3.1%.Based on Least Absolute Shrinkage and Selection regression and subsequent univariate and multivariate Cox regression analyses,extranodal sites≥2,B symptoms,mixed lesion type,and negative multiple myeloma oncogene 1 expression were identified as independent risk factors for PGI-DLBCL.The risk model stratified patients into high-and low-risk groups with significantly different overall survival(P<0.05).Area under the curve values for 1-,3-,and 5-year overall survival were 0.625,0.663,and 0.723 in the training cohort,with consistent performance in the validation cohort.Decision curve analysis indicated favorable clinical utility.CONCLUSION PGI-DLBCL in our cohort showed distinctive clinical features and a predominance of the non-germinal center Bcell-like subtype.Decision curve analysis confirmed the clinical applicability of our prognostic model.Although molecular biomarkers will be needed to improve predictive precision,our model offers a practical tool for early risk identification and individualized management in clinical practice. 展开更多

Web-based libraries,such as D3.js,ECharts.js,and G6.js,are widely used to generate node-link graph visualizations.These libraries allow users to call application programming interfaces(APIs)without identifying the details of the encapsulated techniques such as graph layout algorithms and graph rendering methods.Efficiency requirements,such as visualizing a graph with 3k nodes and 4k edges within 1 min at a frame rate of 30 fps,are crucial for selecting a proper library because libraries generally present different characteristics owing to the diversity of encapsulated techniques.However,existing studies have mainly focused on verifying the advantages of a new layout algorithm or rendering method from a theoretical viewpoint independent of specific web-based libraries.Their conclusions are difficult for end users to understand and utilize.Therefore,a trial-and-error selection process is required.This study addresses this gap by conducting an empirical experiment to evaluate the performance of web-based libraries.The experiment involves popular libraries and hundreds of graph datasets covering node scales from 100 to 200k and edge-to-node ratios from 1 to 10(including complete graphs).The experimental results are the time costs and frame rates recorded using the libraries to visualize the datasets.The authors analyze the performance characteristics of each library in depth based on the results and organize the results and findings into application-oriented guidelines.Additionally,they present three usage cases to illustrate how the guidelines can be applied in practice.These guidelines offer user-friendly and reliable recommendations,aiding users in quickly selecting the desired web-based libraries based on their specific efficiency requirements for node-link graph visualizations. 展开更多
