Effective fault diagnosis is crucial for the reliable running of Electromechanical coupling Systems(EMS),yet hampered by insufficient entity fault data.Digital Twin(DT)technology offers the potential for virtual fault data augmentation and fault diagnosis improvement.However,there is still a lack of an effective and systematic methodology,to decouple complicated EMS entities and construct their full-system DT.To address this,a hierarchical collaborative DT construction framework is proposed for fault data augmentation of EMS.Specially,we decouple EMS entity into the triplet representations of element,data,and relationship,which establish the profound understanding of coupling characteristics from multiple modalities.Furthermore,we develop a hierarchical DT modeling method to mirror these complicated couplings as four-level sub-DTs of space,behavior,process,and status.Each level of sub-DT utilizes the data-mechanism combined technique to balance modeling adaptability and precision.Finally,these heterogeneous sub-DTs are integrated as full-system DT driven by collaborative orchestration algorithm,which achieves the global consistency mirror with the real fault manifestation under diverse fault modes.Experiments on a multi-coupled electromechanical fault test bench validate our framework.Results exhibit the average improvements of 17.29%and 9.97%in accuracy of data augmentation fault classification,confirming its superiority and effectiveness. 展开更多

This manuscript mainly proposed an effective method to well disperse the composite conductive agent which is composed of carbon nanotubes(CNTs)and graphene(Gr)in lithium-ion battery(LIB)slurry.Electrochemical Impedance Spectroscopy(EIS),Scanning Electron Microscopy(SEM)and gravitational sedimentation(GS)are employed to characterize the electrochemical,morphological and stability characterizations of LIB slurry,respectively.Specifically,electrochemical characterizations of LIB electrode slurries are performed by fitting Nyquist plots with a 10-parameter EEC,and quantitative morphological analysis of SEM images is conducted using a Mask R-CNN instance segmentation algorithm,both of which were proposed in our prior published research works.Consequently,the dispersion characterizations of LIB slurry are able to be summarized as follows:LiCoO2 particles are well dispersed in LIB slurry atφcom2=0.5%,by contrast,the composite conductive agent achieves superior coating and networking of LiCoO2 particles under the conditions of bothφcom2=0.5%and mcNTs∶mGr=4∶1,due to the maximized CNTs-Gr synergistic effect.Meanwhile,the formed three-dimensional"long-range"conductive network maintains the stability of its internal skeleton structure during the sedimen-tation of LIB slurry.This finding holds significant potential to advance the application of CNTs/Gr composite conductive agents in LIB slurry. 展开更多

Carotenoid isomerase(CRTISO)is an important enzyme in carotenoid biosynthesis,and it catalyzes the conversion of lycopene precursors to lycopene in several plant species.However,the role of CRTISO in other biochemical processes during plant growth and development remains unclear.Here,we showed that Chinese kale boacrtiso mutants have distinctive characteristics,including a yellowgreen hue and glossy appearance,and this contrasts with the dark green and glaucous traits observed in wild-type(WT)plants.Analysis of pigments in mutants revealed that the reduction in the content of carotenoids and chlorophylls contributed to the yellow-green coloration observed in mutants.An examination of cuticular waxes in Chinese kale indicated that there was a decrease in both the total wax content and the content of individual waxes in boacrtiso mutants(bearing a mutation of BoaCRTISO),which may be caused by the decrease of abscisic acid(ABA)content.The expression of carotenoid,chlorophyll,ABA,and wax biosynthesis genes was downregulated in boacrtiso mutants.This finding confirms that BoaCRTISO regulates the biosynthesis of pigments,ABA,and cuticular waxes in Chinese kale.Our results provide new insights into the interplay between plant pigment and cuticular wax metabolic pathways in Brassica vegetables. 展开更多

This study conducted karyotype analysis on 56 Chinese kale varieties from Guangdong and Fujian provinces using conventional chromosome analysis methods.The varieties were categorized into four groups based on their origin and flower color:white-flower Chinese kale originating from Guangdong(GW),yellow-flower Chinese kale originating from Guangdong(GY),white-flower Chinese kale originating from Fujian(FW),and yellow-flower Chinese kale originating from Fujian(FY).Karyotype differences among the four groups of Chinese kale were analyzed,and the evolutionary relationship between yellow-flower and white-flower Chinese kale from the two regions was inferred based on karyotype parameters.The results indicated that all Chinese kale varieties were diploid with 2n=2x=18,including a pair of satellites.The chromosome types included median-centromere(m)and sub-median-centromere(sm),and the karyotypes were 1A and 2A,a sper karyotype asymmetry index.The karyotype 1A of Chinese kale was identified for the first time.Partial least squares discriminant analysis(PLS-DA)identified nine karyotypic indicators that differentiated the four groups,and these differences were further visualized using heatmaps and box plots.Based on the evolution trends in the four groups and PLS-DA analysis,it was speculated that white-flower Chinese kale originated from Guangdong,yellow-flower Chinese kale originated from Fujian,and GY and FW were derived from the cross of GW and FY.This study provides a reference for understanding the genetic relationships between Chinese kale in Guangdong and Fujian,and offers a cytological basis for the evolution,hybridization,and phylogenetic relationships of Chinese kale. 展开更多

Based on ERA5 reanalysis and CN05.1 gridded observational datasets,this study investigates key meteorological drivers and cross-seasonal mechanisms influencing summer(June–July–August)run-of-river(ROR)hydropower generation in the middle reaches of the Yangtze River Basin(MYRB).Results reveal synergistic regulation by the meridional displacement of the subtropical westerly jet(SWJ)and Pakistan convective activity through East Asian atmospheric circulation.Southward(northward)SWJ shifts coupled with weakened(intensified)Pakistan convection enhance(reduce)MYRB precipitation while lowering(elevating)temperatures,thereby increasing(decreasing)ROR hydropower generation.Precursor analysis identifies spring negative(positive)sea surface temperature anomalies in the northwestern Indian Ocean may strengthen(weaken)meridional thermal gradients,forcing corresponding SWJ displacements.Concurrently,Central Asian cooling(warming)in spring modifies the Arabian Sea–Central Asia pressure gradient,suppressing(enhancing)South Asian monsoon moisture transport to Pakistan.These oceanic–terrestrial thermal coupling mechanisms demonstrate significant predictability for MYRB hydropower variability. 展开更多

Single-atom catalysts(SACs)have demonstrated excellent performance in heterogeneous catalytic reactions owing to their maximized atomic efficiency,distinctive geometric,and electronic configurations.However,the efficacy of SACs remains limited for certain reactions requiring simultaneous activation of multiple reactants over metallic active sites.Herein,we report an atomically dispersed Pt1Ru1 dual-atom pair site anchored on nanodiamond@graphene(ND@G)for CO oxidation.The Pt1Ru1 dual-atom catalyst shows an exceptional turnover frequency(TOF)of 17.6.10-2s-1at significantly lower temperature(30℃),achieving a tenfold increase in TOF compared to singleatom Pt1/ND@G catalyst(1.5.10-2s-1)and surpassing to previously reported Pt-based catalysts under similar conditions.Moreover,the catalyst demonstrates excellent stability,maintaining its activity for 40 h at 80℃without significant deactivation.The superior catalytic performance of Pt-Ru dual-atom catalysts is attributed to the synergistic effect between Pt and Ru atoms with enhanced metallicity for improving simultaneous adsorption and activation of CO and O2,and the tuning of conventional competitive reactant adsorption into a non-competitive pathway over dual-atom pair sites.The present work manifests the advantages of dual-atom pair sites in heterogeneous catalysis and paves the way for precise design of catalysts at the atomic scale. 展开更多

The 1-DNJ contents of silkworm larvae change significantly with their developmental stages. The male larvae showed higher accumulation efficiency of 1-DNJ than the females and also a significant variation was observed among the silkworm strains. The present results show that tissue distribution of 1-DNJ was significantly higher in blood,digestive juice,and alimentary canal,but no 1-DNJ was observed in the silkgland. Moreover,1-DNJ was not found in silkworms fed with artificial diet that does not contain mulberry leaf powder. This proves that silkworms obtain 1-DNJ from mulberry leaves; they could not synthesize 1-DNJ by themselves. The accumulation and excretion of 1-DNJ change periodically during the larval stage. There was no 1-DNJ in the newly-hatched larvae and 1-DNJ was mainly accumulated during the early and middle stages of every instar,while excreted at later stages of larval development. Further,it is possible to extract 1-DNJ from the larval feces and it is optimal to develop the 1-DNJ related products for diabetic auxiliary therapy. 展开更多

Metal halide perovskite solar cells(PSCs) have attracted extensive research interest for next-generation solution-processed photovoltaic devices because of their high solar-to-electric power conversion efficiency(PCE)and low fabrication cost. Although the world's best PSC successfully achieves a considerable PCE of over 20% within a very limited timeframe after intensive efforts, the stability, high cost, and up-scaling of PSCs still remain issues. Recently, inorganic perovskite material, CsPbBr_3, is emerging as a promising photo-sensitizer with excellent durability and thermal stability, but the efficiency is still embarrassing. In this work, we intend to address these issues by exploiting CsPbBr_3 as light absorber, accompanied by using Cu-phthalocyanine(CuPc) as hole transport material(HTM) and carbon as counter electrode. The optimal device acquires a decent PCE of 6.21%, over 60% higher than those of the HTM-free devices. The systematic characterization and analysis reveal a more effective charge transfer process and a suppressed charge recombination in PSCs after introducing CuPc as hole transfer layer. More importantly, our devices exhibit an outstanding durability and a promising thermal stability, making it rather meaningful in future fabrication and application of PSCs. 展开更多

The carotenoid isomerase gene(BoaCRTISO)of Chinese kale was targeted and edited using the CRISPR/Cas9 system in the present study.The results showed a high mutation rate(81.25%),and 13 crtiso mutants were obtained.Only two types of mutations,insertions and replacements,were found.Both the total and individual carotenoid and chlorophyll concentrations of the biallelic and homozygous mutants were reduced,and the total levels declined by 11.89–36.33%.The color of the biallelic and homozygous mutants changed from green to yellow,likely reflecting a reduction in the color-masking effect of chlorophyll on carotenoids.The expression levels of most carotenoid and chlorophyll biosynthesis-related genes,including CRTISO,were notably lower in the mutants than in the WT plants.In addition,the functional differences between members of this gene family were discussed.In summary,these findings indicate that CRISPR/Cas9 is a promising technique for the quality improvement of Chinese kale and other Brassica vegetables. 展开更多

Xin’anbian Oilfield of the Ordos Basin is the large tight oilfield to be first exploration discovery in china.The production of tight oil increased significantly in recent years.It shows great exploration potential of Chang 7 tight oil.But the physical property and hydrocarbon enrichment characteristics of Chang 7 tight oil reservoirs were rarely studied,The forming conditions of tight oil reservoirs are systematically summarized and analyzed through the study of hydrocarbon generation,sedimentary reservoirs and hydrocarbon migration and accumulation based on production and core experimental data.The result shows that,The porosity of the Chang 72reservoir mainly distributed in 5.0-11.0%,average at 7.9%,The permeability mainly distributed in 0.04-0.18×10-3μm2,average at 0.12×10-3μm2,The pore diameters of the tight oil reservoir distributed in 2-8μm.The high-quality Chang 73source rocks and the micropsammite of Chang 72subaqueous distributary channel were widely distributed in the study area.The lenticular or banded sand bodies are distributed among mudstone or hydrocarbon source rocks and have the advantage of migration distance for hydrocarbon accumulation.The reservoir space is composed of micro-nanometer pores and throat,that is formed in the process of increasing pressure during hydrocarbon generation and hydrocarbon accumulation.The Chang 7 tight oil was generated in the early Cretaceous and injected into the sand of the subaqueous distributary channel driven by continuous hydrocarbon generation supercharging.The formation and accumulation of tight oil reservoirs are mainly controlled by source rocks,sedimentary microfacies and reservoirs of good quality. 展开更多

The boreal spring Antarctic Oscillation(AAO)has a significant impact on the spring and summer climate in China.This study evaluates the capability of the NCEP's Climate Forecast System,version 2(CFSv2),in predicting the boreal spring AAO for the period 1983-2015.The results indicate that CFSv2 has poor skill in predicting the spring AAO,failing to predict the zonally symmetric spatial pattern of the AAO,with an insignificant correlation of 0.02 between the predicted and observed AAO Index(AAOI).Considering the interannual increment approach can amplify the prediction signals,we firstly establish a dynamical-statistical model to improve the interannual increment of the AAOI(DY AAOI),with two predictors of CFSv2-forecasted concurrent spring sea surface temperatures and observed preceding autumn sea ice.This dynamical-statistical model demonstrates good capability in predicting DY AAOI,with a significant correlation coeffcient of 0.58 between the observation and prediction during 1983-2015 in the two-year-out cross-validation.Then,we obtain an improved AAOI by adding the improved DY AAOI to the preceding observed AAOI.The improved AAOI shows a significant correlation coeffcient of 0.45 with the observed AAOI during 1983-2015.Moreover,the unrealistic atmospheric response to March-April-May sea ice in CFSv2 may be the possible cause for the failure of CFSv2 to predict the AAO.This study gives new clues regarding AAO prediction and short-term climate prediction. 展开更多

Stimuli-triggered drug delivery systems hold vast promise in local infection treatment for the site-specific targeting and shuttling of drugs.Herein,chitosan conjugates(SPCS)installed with sialic acid(SA)and phenylboronic acid(PBA)were synthesized,of which SA served as targeting ligand for coccidium and reversible-binding bridge for PBA.The enhanced drug-loading capacity of SPCS micelles was attributed to a combination assembly from hydrophobicity-driving and reversible borate bridges.The drug-loaded SPCS micelles shared superior biostability in upper gastrointestinal tract.After reaching the lesions,the borate bridges were snipped by carbohydrates under a higher pH followed by accelerated drug release,while SA exposure on micellar surface facilitated drug cellular internalization to eliminate parasites inside.The drugmicelles revealed an enhanced anti-coccidial capacity with a higher index of 185.72 compared with commercial preparation.The dual-responsive combination of physicochemical assembly could provide an efficient strategy for the exploitation of stable,safe and flexible anti-infectious drug delivery systems. 展开更多

Brassinazole resistant 1(BZR1),a brassinosteroid(BR)signaling component,plays a pivotal role in regulating numerous specific developmental processes.Our study demonstrated that exogenous treatment with 2,4-epibrassinolide(EBR)significantly enhanced the accumulation of carotenoids and chlorophylls in Chinese kale(Brassica oleracea uar.alboglabra).The underlying mechanism was deciphered through yeast one-hybrid(Y1H)and dual-luciferase(LUC)assays,whereby BoaBZR1.1 directly interacts with the promoters of BoaCRTISO and BoaPSY2,activating their expression.This effect was further validated through overexpression of BoaBZR1.1 in Chinese kale calli and plants,both of which exhibited increased carotenoid accumulation.Additionally,qPCR analysis unveiled upregulation of carotenoid and chlorophyll biosynthetic genes in the T1 generation of BoaBZR1.1-overexpressing plants.These findings underscored the significance of BoaBZR1.1-mediated BR signaling in regulating carotenoid accumulation in Chinese kale and suggested the potential for enhancing the nutritional quality of Chinese kale through genetic engineering of BoaBZR1.1. 展开更多

Soy whey(SW)is generated as process waste while preparing soy protein isolates(SPI),and causing severe environmental pollution.Therefore,its value-added utilization is of prime importance for transforming and upgrading traditional industry.This study aims to utilize SW as a substrate for the growth of probiotics and produce a SW based synbiotics.By a series of trials,the effect of the dietary supplementation with this fermented SW(FSW)was analyzed on ICR mice's body weight,metabolites,and intestinal microbiota in 4 weeks.The results showed that,when SW was concentrated 15 times,the count of viable Lactobacillus casei reached 3.4×109 CFU/mL by liquid fermentation method,which was the highest viable cell count among all test strains.In this FSW,the protein,amino acid,total dietary fibre,soluble dietary fibre,and oligosaccharide were 2.10%,1.63%,0.52%,0.51% and 0.79%,respectively.Compared to two control group,the total yields of the short chain fatty acids(SCFAs)were significantly improved(75%-125% at average),while the SCFAs structure was also significantly changed(especially acetic acid and butyrate)in the faeces of mice fed FSW.Meanwhile,FSW dietary addition was associated with the diversity and richness of the intestinal microbiota.Obviously,with mice's body weight loss,Firmicutes/Bacteroides ratio reduced accordingly(<1.21),and the abundance of Akkermansia muciniphila was significantly increased(the maximum amount was about 0.013%).In summary,our results indicated that the dietary supplementation of FSW affected mice's intestinal microbiota and metabolism and improved their health profile. 展开更多

Titanium-boron(Ti-B)compounds exhibit great promise as superhard materials due to titanium's low atomic mass and abundant valence electrons.In this work,we systematically investigated the crystal structures of TiB6under pressures ranging from 0-100 GPa using the CALYPSO algorithm combined with first-principles calculations.Phonon dispersion analysis and elastic-constant evaluations confirm the dynamic and mechanical stability of five predicted TiB6structures.Notably,theα-Amm2-TiB6structure was predicted to have a remarkable Vickers hardness of 56 GPa,as estimated by Chen's empirical model.All five structures are thermodynamically stable under ambient conditions,suggesting viable synthetic pathways.Their outstanding bulk moduli and ultrahigh hardness further classify them as potential incompressible and superhard materials.These theoretical insights lay a robust foundation for future experimental synthesis efforts. 展开更多

Permanganate(Mn(VII))is a commonly used oxidant for water treatment.However,manganese dioxide(MnO2)produced in situ during permanganate oxidation reactions significantly interferes with the spectrophotometric measurement of Mn(VII)when using the previously reported spectrophotometry.In this study,a convenient,low-cost,and reliable spectrophotometry method was firstly established for measuring trace Mn(VII)(μmol/L−level)during the permanganate oxidation reactions without the need to filter out MnO2.The method was based on the oxidation of 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonate)(ABTS)by Mn(VII)to produce a stable green radical(ABTS•+)under mildly alkaline conditions(pH≥8),with detection at long wavelengths(i.e.,732 nm and 820 nm).The strong resistance to interference from MnO2 of the modified ABTS method was attributed to the inertness of MnO2 toward ABTS under mildly alkaline conditions and the relatively low molar absorptivity of MnO2 at long wavelengths compared to ABTS•+.Using the characteristic peak at 732 nm as the detection wavelength,the sensitivity of the modified ABTS method for the Mn(VII)measurement was determined to be 4.84×104 L/(mol·cm).Additionally,the modified ABTS method exhibited high tolerance towards common environmental background matrices and was reliable in measuring the Mn(VII)concentration in natural water samples.The accuracy of the modified ABTS method for the measurement of Mn(VII)in the presence of MnO2 was also validated by comparing different detection methods.Furthermore,the modified ABTS method was successfully applied to detect the variation of Mn(VII)concentration during diclofenac removal with the humic acid-enhanced Mn(VII)process. 展开更多

Baby mustard is rich in nutrients;however,it is prone to postharvest yellowing and wilting,which leads to the loss of nutritional components.Folic acid,an important water-soluble vitamin,exhibits substantial physiological antioxidant activity.This study explored the impact of folic acid immersion treatments on the visual quality and health-promoting compounds of baby mustard stored at 20◦C.The results showed that,compared with other concentrations,5 mg L−1 folic acid treatment(F5)was the most effective in improving baby mustard storability.In terms of appearance and sensory acceptability,the F5 treatment was more effective than 0 mg L−1 folic acid treatment(CK),while the a*value was significantly lower than that of the control.In terms of pigments,chlorophyll and carotenoid contents were higher in the F5-treated samples than in the control,contributing to improved color retention during storage.In addition,the F5 treatment maintained glucosinolate content,especially by preserving aliphatic glucosinolates.This treatment also increased the ascorbic acid content of baby mustard,increased total phenolic content,and improved antioxidant activity.Overall,these findings indicate that the application of 5 mg L−1 folic acid is a promising strategy for improving the postharvest quality and commercial value of baby mustard,providing a theoretical basis and technical support for its preservation during room-temperature storage. 展开更多

As emerging two-dimensional(2D)materials,carbides and nitrides(MXenes)could be solid solutions or organized structures made up of multi-atomic layers.With remarkable and adjustable electrical,optical,mechanical,and electrochemical characteristics,MXenes have shown great potential in brain-inspired neuromorphic computing electronics,including neuromorphic gas sensors,pressure sensors and photodetectors.This paper provides a forward-looking review of the research progress regarding MXenes in the neuromorphic sensing domain and discussed the critical challenges that need to be resolved.Key bottlenecks such as insufficient long-term stability under environmental exposure,high costs,scalability limitations in large-scale production,and mechanical mismatch in wearable integration hinder their practical deployment.Furthermore,unresolved issues like interfacial compatibility in heterostructures and energy inefficiency in neu-romorphic signal conversion demand urgent attention.The review offers insights into future research directions enhance the fundamental understanding of MXene properties and promote further integration into neuromorphic computing applications through the convergence with various emerging technologies. 展开更多

A Laue microdiffraction beamline(BL03HB) was constructed at the Shanghai Synchrotron Radiation Facility(SSRF).This beamline features two consecutive focusing points in two different sectors within its end station, the first dedicated to protein crystallography and the other tailored to materials science applications. Based on a superbend dipole magnet with a magnetic field of 2.29 T, a two-stage focusing design was implemented with two sets of Kirkpatrick-Baez mirrors to achieve a micro white beam as small as 4.2 μ m ×4.3 μ m at the first sector and 0.9 μ m ×1.3 μ m at the second sector in the standard beamline operation mode at SSRF. The X-ray microbeam in the two sectors can be easily switched between monochromatic and white beams by moving a four-bounce monochromator in or out of the light path, respectively. In the protein crystallography sector, white-beam Laue microdiffraction was demonstrated to successfully determine the structure of protein crystals from only a few images of diffraction data collected by a Pilatus 2 M area detector. In the materials science sector,the white-beam Laue diffraction was collected in a reflection geometry using another Pilatus 2 M area detector, which could map the microstructural distribution on the sample surface by scanning the samples. In general, the BL03HB beamline promotes the application of Laue microdiffraction in both protein crystallography and materials science. This paper presents a comprehensive overview of the BL03HB beamline, end station, and the first commission results. 展开更多

With the deep integration of energy and information networks,the low-carbon,efficient,and economical oper-ation and management of integrated energy systems are increasingly driven by digital twins and large artificial intelligence models,which rely heavily on the robust support of the Internet of Things and big data.However,the data interaction process within energy systems faces issues such as varying privacy protection demands and conflicts of interest among participating entities,leading to development bottlenecks like prominent data silos,a lack of secure sharing mechanisms,and low collaborative efficiency.As a novel infrastructure for data resource circulation,the energy data space integrates various software and hardware encryption methods to construct a trusted execution environment,providing solutions for the secure sharing and value realization of energy data re-sources.Based on a decentralized yet adjustable underlying architecture,the energy data space can be adaptively designed according to the coupling characteristics of energy and information flows,meeting the real-time,effi-ciency,and scalability requirements of cross-entity systems and large-scale businesses.This paper investigates,analyzes,and summarizes technical routes through which the energy data space can facilitate the digital and intelligent transformation of integrated energy systems.It also elaborates on the supporting role of the energy data space in the conceptual architecture,technical support,application scenarios,and value creation of energy industry upgrading. 展开更多
