1The impacts of conservation agriculture on crop yield in China depend on specific practices, crops and cropping regions显示文摘For smooth and wide application of conservation agriculture(CA), remaining uncertainties about its impacts on crop yield need to be reduced. Based on previous field experiments in China, a meta-analysis was performed to quantify the actual impacts of CA practices(NT: no/reduced-tillage only, CTSR: conventional tillage with straw retention, NTSR: NT with straw retention) on crop yields as compared to conventional tillage without straw retention(CT).Although CA practices increased crop yield by 4.6% on average, there were large variations in their impacts. For each CA practice, CTSR and NTSR significantly increased crop yield by 4.9%and 6.3%, respectively, compared to CT. However, no significant effect was found for NT. Among ecological areas, significant positive effects of CA practices were found in areas with an annual precipitation below 600 mm. Similar effects were found in areas with annual mean air temperature above 5 °C. For cropping regions, CA increased crop yield by 6.4% and 5.5%compared to CT in Northwest and South China, respectively, whereas no significant effects were found in the North China and Northeast China regions. Among crops, the positive effects of CA practices were significantly higher in maize(7.5%) and rice(4.1%) than in wheat(2.9%). NT likely decreased wheat yield. Our results indicate that there are great differences in the impacts of CA practices on crop yield, owing to regional variation in climate and crop types. CA will most likely increase maize yield but reduce wheat yield. It is strongly recommended to apply CA with crop straw retention in maize cropping areas and seasons with a warm and dry climate pattern.Chengyan Zheng Yu Jiang Changqing Chen Yanni Sun Jinfei Feng Aixing Deng Zhenwei Song Weijian Zhang 2014The Crop Journal2014,2,5:15
2A novel four-way combining catalysts for simultaneous removal of exhaust pollutants from diesel engine显示文摘A novel four-way combining catalysts containing double layers was applied to simultaneously remove four kinds of exhaust pollutants(NOx,CO,HC and PM) emitted from diesel engine.The four-way catalysts were characterized using scanning electron microscope(SEM) and Ultraviolet visible diffuse reflectance spectroscopy(UV-Vis DRS).Their catalytic performances were evaluated by temperature-programmed reaction technology.The double layer catalysts could effectively remove the four main pollutants.The highest catalytic activity was given by the two-layered catalysts of La0.6K0.4CoO3/Al2O3 and W/HZSM-5.Under the simulated exhaust gases conditions,the peak temperature of the soot combustion was 421°C,the maximal conversion of NO to N2 was 74%,the temperature of the HC total conversion was 357°C,and the maximum conversion ratio of CO was 99%.Jian Liu,Jie Xu,Zhen Zhao,Aijun Duan,Guiyuan Jiang,Yanni Jing State Key Laboratory of Heavy Oil Processing,China University of Petroleum,Beijing 102249,China. 2010Journal of Environmental Sciences2010,22,7:11
3A novel xeno-free and feeder-cell-free system for human pluripotent stem cell culture显示文摘While human induced pluripotent stem cells(hiPSCs)have promising applications in regenerative medicine,most of the hiPSC lines available today are not suitable for clinical applications due to contamination with nonhuman materials,such as sialic acid,and potential pathogens from animal-product-containing cell culture systems.Although several xeno-free cell culture systems have been established recently,their use of human fibroblasts as feeders reduces the clinical potential of hiPSCs due to batch-to-batch variation in the feeders and time-consuming preparation processes.In this study,we have developed a xeno-free and feeder-cell-free human embryonic stem cell(hESC)/hiPSC culture system using human plasma and human placenta extracts.The system maintains the self-renewing capacity and pluripotency of hESCs for more than 40 passages.Human iPSCs were also derived from human dermal fibroblasts using this culture system by overexpressing three transcription factors—Oct4,Sox2 and Nanog.The culture system developed here is inexpensive and suitable for large scale production.Qihui Wang Xiaoning Mou Henghua Cao Qingzhang Meng Yanni Ma Pengcheng Han Junjie Jiang Hao Zhang Yue Ma 2012Protein & Cell2012,3,1:6
4E17110 promotes reverse cholesterol transport with liver X receptor β agonist activity in vitro显示文摘Liver X receptor(LXR) plays an important role in reverse cholesterol transport(RCT), and activation of LXR could reduce atherosclerosis. In the present study we used a cell-based screening method to identify new potential LXRβ agonists. A novel benzofuran-2-carboxylate derivative was identified with LXRβ agonist activity: E17110 showed a significant activation effect on LXRβ with an EC50 value of 0.72 μmol/L. E17110 also increased the expression of ATP-binding cassette transporter A1(ABCA1) and G1(ABCG1) in RAW264.7 macrophages. Moreover, E17110 significantly reduced cellular lipid accumulation and promoted cholesterol efflux in RAW264.7 macrophages. Interestingly, we found that the key amino acids in the LXRβ ligand-binding domain had distinct interactions with E17110 as compared to TO901317. These results suggest that E17110 was identified as a novel compound with LXRβ agonist activity in vitro via screening, and could be developed as a potential anti-atherosclerotic lead compound.Ni Li Xiao Wang Peng Liu Duo Lu Wei Jiang Yanni Xu Shuyi Si 2016Acta Pharmaceutica Sinica B2016,6,3:3
5Hydrogel-based flexible materials for diabetes diagnosis,treatment,and management显示文摘Diabetes is a chronic metabolic disease characterized by high glucose concentration in blood.Conventional management of diabetes requires skin pricking and subcutaneous injection,causing physical pain and physiological issues to diabetic individuals.Hydrogels possess unique advantages such as lightweight,stretchability,biocompatibility,and biodegradability,offering the opportunities to be integrated as flexible devices for diabetes management.This review highlights the development of hydrogels as flexible materials for diabetes applications in glucose monitoring,insulin delivery,wound care,and cell transplantation in recent years.Challenges and prospects in the development of hydrogel-based flexible devices for personalized management of diabetes are discussed as well.Jiang Song Yanni Zhang Siew Yin Chan Zhaoyi Du Yinjia Yan Tengjiao Wang Peng Li Wei Huang 2021npj Flexible Electronics2021,5,1:2

7Effective E.coli inactivation of core-shell ZnO@ZIF-8 photocatalysis under visible light synergize with peroxymonosulfate:Efficiency and mechanism显示文摘How to utilize inexhaustible solar light as a means of disinfection technology for its cheap and green remains a challenge.In this work,core-shell ZnO@ZIF-8 was synthesized and used for bacterial inactivation synergizing with peroxymonosulfate(PMS)under visible light irradiation.It took 50 min to achieve thorough sterilization for 7.5-log Escherichia coli(E.coli)cells in vis/PMS/ZnO@ZIF-8 system,compared with that 4.5-log reduction completed in vis/PMS/ZnO system under the same conditions.The enhanced photocatalytic disinfection mechanisms of fabricated ZnO@ZIF-8 were investigated by UV-vis diffuse reflectance spectra,electrochemical impedance spectra and Mott-Schottky plots.The promoted bactericidal efficiency was attributed to higher charge-separation efficiency and stronger oxidation ability of photo-generated holes.Moreover,it was found that^(1)O_(2)and·OH induced bacterial cell lesion process,and the former was the main active species.The external reactive oxygen species(ROS)caused a series of cell wall damage,intercellular ROS up-regulation and genome DNA unwinding,finally resulted in irreversible bacterial death.A two-route mechanism in vis/PMS/ZnO@ZIF-8 system was proposed,in which the generation of^(1)O_(2)was supposed as the product of the oxygen oxidation of photo-generated holes and PMS dissociation.Our work is expected to provide advanced information about a low-cost water disinfection technology of visible light photocatalysis.Yanni Jiang Zhaokun Xiong Jianbo Huang Feng Yan Gang Yao Bo Lai 2022Chinese Chemical Letters2022,33,1:2
8L-distribution for multilook polarimetric SAR data and its application in ship detection显示文摘Statistical modeling based on the product model is an effective method to fit the sea clutter of polarimetric synthetic aperture radar(PolSAR) images in nonhomogeneous regions. The generalized Gamma distribution(GΓD) is a kind of distribution with wide coverage, including Weibull, Gamma, inverse Gamma,Fisher, and other distributions;it can be used as a textural variable in the product model because of its coverage and flexibility. The L-distribution is presented to describe the statistical distribution in this product model case. The probability distribution function(PDF) of the multilook covariance matrix is obtained in the L-distribution product model, which is presented in a closed form. Moreover, the statistics are applied to ship detection by the optimal polarimetric detector(OPD), and the analytical expressions of the probability of false alarm(PFA) and the probability of detection(PD) are both derived, which are also extended to derive the PFA of the MPWF detector. Finally, the simulated and measured data are used to verify the correctness of the theoretical derivation, and the results show that our derivations are all correct and effective.Tao LIU Tao TANG Ziyuan YANG Yanni JIANG Sheng GAO Guangquan CHENG 2021Science China(Information Sciences)2021,64,12:2
9LncRNA NKILA suppresses airway hyper reactivity via interfering the facilitation of MUC5AC and MUC5B mediated by GALNT2显示文摘Glycosylation of mucins mediated by N-acetylgalactosaminyltransferases(GALNTs)is closely related to respiratory diseases such as asthma and chronic obstructive pulmonary disease(COPD).In addition,long non-coding RNAs(LncRNAs)participate in physiological and pathological processes through various epigenetic mechanisms.In this study,we found that a novel LncRNA named NKILA combined with multiple mucins and GALNTs potentially by several bioinformatics methods,and we used quantitative real-time PCR(RT-qPCR)to detect the expressions of NKILA,MUC5AC,MUC5B,and GALNT2 mRNA in 50 cases of asthma samples and 19 cases of normal samples,whose results showed that the expression of NKILA was significantly decreased in asthmatic samples,negatively correlated with the severity of asthma and the expressions of MUC5AC and MUC5B,while GALNT2 was significantly increased in asthmatic tissues,and positively correlated with the severity of asthma and the expressions of MUC5AC and MUC5B.In vitro,we used transient transfection technology to overexpress or interfere with NKILA and GALNT2 and then detected the expressions of MUC5AC and MUC5B via RT-qPCR and Western blot,which demonstrated GALNT2 can promote the expressions of MUC5AC and MUC5B protein,while NKILA could inhibit this effect.Furthermore,co-immunoprecipitation results showed that GALNT2 could bind to MUC5AC and MUC5B protein.RNA immunoprecipitation and RNA pull-down experiments showed that NKILA could bind to GALNT2.These evidences suggested that there are correlations among the expression of NKILA,GALNT2,MUC5AC,and MUC5B proteins in asthmatic patients.Mechanically,we concluded that NKILA can suppress the O-linked glycosylation of MUC5AC and MUC5B proteins by binding to GALNT2 and inhibit the expression of MUC5AC and MUC5B proteins.Our researches provided a potential therapeutic target for AHR.YONGLI ZHANG YIZHAN CAO BO ZHU YANNI JIANG PENGCHONG LIANG 2021BIOCELL2021,45,1:1
10Neural basis for successful encoding and retrieval of prospective memory显示文摘Prospective memory (PM) refers to memory for future intentions.Difference due to memory (Dm effect) is the difference in neural activity related to stimuli that were subsequently remembered or forgotten.Using event-related potentials (ERPs),the present study investigated the Dm effect for PM using a subsequent task-switching paradigm.The results showed that a Dm effect of ERP P150 was more positive-going for later PM hit trials than for later PM forgotten trials during 100–200 ms.This Dm effect may reflect the process for the production of future intention or the process for attention.Consistent with previously reported Dm effects of other types of memory,we found that the fbN2 (250–280 ms) and late positivity component (400–700 ms) were stronger in later PM hit trials than in forgotten trials.The fbN2 was evoked by Chinese characters.The late positivity component was related to the precise encoding process.In conclusion,because of the early P150,PM encoding appears to be somewhat different from previously identified Dm effects.However,further research is needed.Our findings reveal that Dm effects of PM share similar characteristics with known Dm effects of other types of episodic memory after the very early stage of neural processing.CHEN YanNi GUO ChunYan JIANG Yang 2011Science China(Life Sciences)2011,54,6:1

12Remote control of the recruitment and capture of endogenous stem cells by ultrasound for in situ repair of bone defects显示文摘Stem cell-based tissue engineering has provided a promising platform for repairing of bone defects.However,the use of exogenous bone marrow mesenchymal stem cells(BMSCs)still faces many challenges such as limited sources and potential risks.It is important to develop new approach to effectively recruit endogenous BMSCs and capture them for in situ bone regeneration.Here,we designed an acoustically responsive scaffold(ARS)and embedded it into SDF-1/BMP-2 loaded hydrogel to obtain biomimetic hydrogel scaffold complexes(BSC).The SDF-1/BMP-2 cytokines can be released on demand from the BSC implanted into the defected bone via pulsed ultrasound(p-US)irradiation at optimized acoustic parameters,recruiting the endogenous BMSCs to the bone defected or BSC site.Accompanied by the daily p-US irradiation for 14 days,the alginate hydrogel was degraded,resulting in the exposure of ARS to these recruited host stem cells.Then another set of sinusoidal continuous wave ultrasound(s-US)irradiation was applied to excite the ARS intrinsic resonance,forming highly localized acoustic field around its surface and generating enhanced acoustic trapping force,by which these recruited endogenous stem cells would be captured on the scaffold,greatly promoting them to adhesively grow for in situ bone tissue regeneration.Our study provides a novel and effective strategy for in situ bone defect repairing through acoustically manipulating endogenous BMSCs.Yanni He Fei Li Peng Jiang Feiyan Cai Qin Lin Meijun Zhou Hongmei Liu Fei Yan 2023Bioactive Materials2023,,3:1
13Hybridoma-derived neutralizing monoclonal antibodies against Beta and Delta variants of SARS-CoV-2 in vivo显示文摘Neutralizing monoclonal antibodies(mAb)are a major therapeutic strategy for the treatment of severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)infection.The continuous emergence of new SARS-CoV-2 variants worldwide has increased the urgency for the development of new mAbs.In this study,we immunized mice with the receptor-binding domain(RBD)of the SARS-CoV-2 prototypic strain(WIV04)and screened 35 RBDspecific mAbs using hybridoma technology.Results of the plaque reduction neutralization test showed that 25 of the mAbs neutralized authentic WIV04 strain infection.The 25 mAbs were divided into three categories based on the competitive enzyme-linked immunosorbent assay results.A representative mAb was selected from each category(RD4,RD10,and RD14)to determine the binding kinetics and median inhibitory concentration(IC_(50))of WIV04 and two variants of concern(VOC):B.1.351(Beta)and B.1.617.2(Delta).RD4 neutralized the B.1.617.2 variant with an IC50 of 2.67 ng/mL;however,it completely lost neutralizing activity against the B.1.351 variant.RD10 neutralized both variants with an IC50 exceeding 100 ng/mL;whereas RD14 neutralized two variants with a higher IC50(>1 mg/mL).Animal experiments were performed to evaluate the protective effects of RD4 and RD10 against various VOC infections.RD4 could protect Adv-hACE2 transduced mice from B.1.617.2 infection at an antibody concentration of 25 mg/kg,while RD10 could protect mice from B.1.351 infection at an antibody concentration of 75 mg/kg.These results highlight the potential for future modifications of the mAbs for practical use.Qianran Wang Lu Peng Yanqiu Nie Yanni Shu Huajun Zhang Zidan Song Yufeng Li Hengrui Hu Liushuai Li Xi Wang Jia Liu Jiang Li Zhengli Shi Fei Deng Yu Guo Yiwu Zhou Bing Yan Zhihong Hu Manli Wang 2023Virologica Sinica2023,38,2:0
14Predicting the pathological status of mammographic microcalcifications through a radiomics approach显示文摘Objective The study aimed to develop a machine learning(ML)-coupled interpretable radiomics signature to predict the pathological status of non-palpable suspicious breast microcalcifications(MCs).Methods We enrolled 463 digital mammographical view images from 260 consecutive patients detected with non-palpable MCs and BI-RADS scored at 4(training cohort,n=428;independent testing cohort,n=35)in the First Affiliated Hospital of Nanjing Medical University between September 2010 and January 2019.Subsequently,837 textures and 9 shape features were subsequently extracted from each view and finally selected by an XGBoostembedded recursive feature elimination technique(RFE),followed by four machine learning-based classifiers to build the radiomics signature.Results Ten radiomic features constituted a malignancy-related signature for breast MCs as logistic regression(LR)and support vector machine(SVM)yielded better positive predictive value(PPV)/sensitivity(SE),0.904(95%CI,0.865–0.949)/0.946(95%CI,0.929–0.977)and 0.891(95%CI,0.822–0.939)/0.939(95%CI,0.907–0.973)respectively,outperforming their negative predictive value(NPV)/specificity(SP)from 10-fold crossvalidation(10FCV)of the training cohort.The optimal prognostic model was obtained by SVM with an area under the curve(AUC)of 0.906(95%CI,0.834–0.969)and accuracy(ACC)0.787(95%CI,0.680–0.855)from 10FCV against AUC 0.810(95%CI,0.760–0.960)and ACC 0.800 from the testing cohort.Conclusion The proposed radiomics signature dependens on a set of ML-based advanced computational algorithms and is expected to identify pathologically cancerous cases from mammographically undecipherable MCs and thus offer prospective clinical diagnostic guidance.Min Li Liyu Zhu Guangquan Zhou Jianan He Yanni Jiang Yang Chen 2021Intelligent Medicine2021,1,3:0
15Exploring the attenuation mechanisms of Dalbergia odorifera leaves extract on cerebral ischemia-reperfusion based on weighted gene co-expression network analysis显示文摘The attenuation function of Dalbergia odorifera leaves on cerebral ischemia-reperfusion(I/R)is little known.The candidate targets for the Chinese herb were extracted from brain tissues through the high-affinity chromatography.The molecular mechanism of D.odorifera leaves on cerebral I/R was investigated.Methods:Serial affinity chromatography based on D.odorifera leaves extract(DLE)affinity matrices were applied to find specific binding proteins in the brain tissues implemented on C57BL/6 mice by intraluminal middle cerebral artery occlusion for 1 h and reperfusion for 24 h.Specific binding proteins were subjected to mass-spectrometry to search for the differentially expressed proteins between control and DLE-affinity matrices.The hub genes were screened based on weighted gene co-expression network analysis(WGCNA).Then,predictive biology and potential experimental verification were performed for the candidate genes.The protective role of DLE in blood-brain barrier damage in cerebral I/R mice was evaluated by the leakage of Evans blue,western blotting,immunohistochemistry,and immunofluorescent staining.Results:952 differentially expressed proteins were classified into seven modules based on WGCNA under soft threshold 6.Based on WGCNA,AKT1,PIK3CA,NOS3,SMAD3,SMAD1,IL6,MAPK1,TGFBR2,TGFBR1,MAPK3,IGF1R,LRG1,mTOR,ROCK1,TGFB1,IL1B,SMAD2,and SMAD518 candidate hub proteins were involved in turquoise module.TGF-β,MAPK,focal adhesion,and adherens junction signaling pathway were associated with candidate hub proteins.Gene ontology analysis demonstrated that candidate hub proteins were related to the TGF-βreceptor signaling pathway,common-partner SMAD protein phosphorylation,etc.DLE could significantly reduce the leakage of Evans blue in mice with cerebral I/R,while attenuating the expression of occludin,claudin-5,and zonula occludens-1.Western blotting demonstrated that regulation of TGF-β/SMAD signaling pathway played an essential role in the protective effect of DLE.Conclusion:Thus,a number of candidate hub proteins were identified based on DLE affinity chromatography through WGCNA.DLE could attenuate the dysfunction of bloodbrain barrier in the TGF-β/SMAD signaling pathway induced by cerebral I/R.JINFANG HU JIANGEN AO LONGSHENG FU YAOQI WU FENG SHAO TIANTIAN XU MINGJIN JIANG SHAOFENG XIONG YANNI LV 2023BIOCELL2023,47,7:0
16Hierarchical structures,surface morphology and mechanical elasticity of lamellar crystals dominated by halogen effects显示文摘To understand the deformation mechanism of molecular crystals under mechanical forces will accelerate the molecular design and preparation of deformable crystals.Herein,the relationship between structural halogenation and molecular-level stacking,micro/nanoscale surface morphology,and macroscopic mechanical properties are investigated.Elastic crystals of halo-pyrimidinyl carbazoles(CzM-Cl,CzM-Br and CzM-I)with lamellar structure and brittle crystal(CzM-F)were quantitatively analyzed by crystal energy framework(CEF)providing the inter/intralayer interaction energy(Inter/Intra-IE).It is revealed that the elastic crystals bend under external force as a result from stronger Intra-IE to prevent cleavage and weaker Inter-IE for the short-range movement of molecules on the slip plane.This research will provide an insight for the molecular design of flexible crystals and facilitate the development of next-generation smart crystal materials.Chuanxin Wei Jianfeng Wang Yanni Zhang Xuehua Ding Yanze Jiang Qiang Zhao Jinyi Lin Jianfeng Zhao Linghai Xie Wei Huang 2023Chinese Chemical Letters2023,34,8:0
17Biochanin A,as the Lrg1/TGF-β/Smad2 pathway blockade,attenuates blood-brain barrier damage after cerebral ischemiareperfusion by modulating leukocyte migration patterns显示文摘Background:Biochanin A is an excellent dietary isoflavone that has the concomitant function of both medicine and foodstuff.The attenuation function of biochanin A on blood-brain barrier(BBB)damage induced by cerebral ischemia-reperfusion remains unclear.Methods:C57BL/6 mice were subjected to 1 h middle cerebral artery occlusion(MCAO)followed by 24 h reperfusion.The infarct volume of the brain was stained by TTC,while leakage of the brain was quantitatively stained by Evans blue,and the neurologic deficit score was measured.Microglial-induced morphologic changes were observed via immunofluorescence staining,and rolling and adhering leukocytes in venules were observed via two-photon imaging,while the inner fluorescein isothiocyanate-albumin of venules were compared with those of surrounding interstitial area through venular albumin leakage.Results:The attenuation effect of biochanin A on tight junction injury was compared in ischemia-reperfusion mice or conventional knockdown of leucine-richα2-glycoprotein 1(Lrg1)mice.Biochanin A could ameliorate BBB injury in mice with cerebral ischemiareperfusion in a dose-dependent manner by strengthening the immunostaining volume of occludin,claudin-5,and zonula occludens-1.The amoeba morphologic changes of microglial combined with the elevated expression of Lrg1 could be relieved under the treatment of biochanin A.Biochanin A played a countervailing role on the rolling leukocytes in the vessel,while the leakage of blood vessels was reduced.Biochanin A diminished its functions to further improved attenuation for tight junction injury on conventional Lrg1-knockout mice,as well as the inhibition effects on TGF-β1,and the phosphorylation of suppressor of mothers against decapentaplegic 2(Smad2)/Smad2 via western blot assay.Conclusion:Biochanin A could alleviate tight junction injury induced by cerebral ischemiareperfusion and blocked the Lrg1/TGF-β/Smad2 pathway to modulate leukocyte migration patterns.LONGSHENG FU JINFANG HU FENG SHAO YAOQI WU WEI BAI MINGJIN JIANG HAO CHEN LIHUA CHEN YANNI LV 2023BIOCELL2023,47,8:0
18Acupuncture on intrauterine growth restriction associated brain injury:case study including use of magnetic resonance imaging显示文摘Brain injury due to intrauterine growth restriction(IUGR) is a thorny clinical problem that often leads to permanent neurological deficits such as cerebral palsy.Few practical therapies can treat an IUGR-associated brain injury.We employed acupuncture to treat a 6-month-old male patient with severe hypoxic-ischemic encephalopathy(HIE) due to IUGR,as confirmed by magnetic resonance imaging(MRI).Three courses of acupuncture treatment significantly improved some of the patient’s clinical characteristics,such as his insensitive responsiveness and motor deficits,with remarkably reversed HIE features on MRI at 1-year of age.This case suggests that acupuncture is a potential treatment option for an IUGRassociated brain injury and warrants further investigation.XIN Zhixiong LI Jiyuan XU Yanni LING Jing JIANG Min YU Yutian 2023Journal of Traditional Chinese Medicine2023,43,3:0
19Optimal design of 6-DOF vibration isolation platform based on transfer matrix method for multibody systems显示文摘The structure parameters of 6-degree of freedom(DOF)vibration isolation platform have a significant effect on its performance.To make the designed vibration isolation platform perform well,non-dominanted sorting genetic algorithm version II(NSGA-II)was applied to optimize its structure based on the transfer matrix method for multibody systems.Firstly,the Jacobian matrix of 6-DOF vibration isolation platform was solved based on kinematics.Secondly,the transfer equation of 6-DOF vibration isolation system was established by the linear transfer matrix method for multibody systems.And the formula of its natural frequency was derived according to the boundary conditions of the system.Thirdly,the manipulability index was constructed based on a dimensionless Jacobian matrix.And a new performance index function was established considering the influence of dynamic isotropic and legs mass.Fourthly,genetic algorithm(GA)and NSGA-II were used to optimize the structure of the 6-DOF vibration isolation platform under the same conditions,respectively.It showed that NSGA-II had higher optimization efficiency,better calculation accuracy and shorter optimization time than that of GA.Finally,NSGA-II was adopted for multi-objective optimization design of 6-DOF vibration isolation platform based on the constraint conditions.Optimal Pareto solutions were obtained,which provides structural parameters for subsequent design work.Therefore,the proposed optimization method and the performance index in this paper provide a theoretical basis for the optimal design of relevant vibration isolation mechanism.Min Jiang Xiaoting Rui Wei Zhu Fufeng Yang Yanni Zhang 2021Acta Mechanica Sinica2021,37,1:0
20A cost-effective ts CUT&Tag method for profiling transcription factor binding landscape显示文摘Knowledge of the transcription factor binding landscape(TFBL)is necessary to analyze gene regulatory networks for important agronomic traits.However,a low-cost and high-throughput in vivo chromatin profiling method is still lacking in plants.Here,we developed a transient and simplified cleavage under targets and tagmentation(tsCUT&Tag)that combines transient expression of transcription factor proteins in protoplasts with a simplified CUT&Tag without nucleus extraction.Our tsCUT&Tag method provided higher data quality and signal resolution with lower sequencing depth compared with traditional ChIP-seq.Furthermore,we developed a strategy combining tsCUT&Tag with machine learning,which has great potential for profiling the TFBL across plant development.Leiming Wu Zi Luo Yanni Shi Yizhe Jiang Ruonan Li Xinxin Miao Fang Yang Qing Li Han Zhao Jiquan Xue Shutu Xu Tifu Zhang Lin Li 2022Journal of Integrative Plant Biology2022,64,11:0
