1Effect of Dark Septate Endophytic Fungus Gaeumannomyces cylindrosporus on Plant Growth, Photosynthesis and Pb Tolerance of Maize (Zea mays L.)显示文摘Dark septate endophytic(DSE) fungi are ubiquitous and cosmopolitan, and occur widely in association with plants in heavy metal stress environment. However, little is known about the effect of inoculation with DSE fungi on the host plant under heavy metal stress.In this study, Gaeumannomyces cylindrosporus, which was isolated from Pb-Zn mine tailings in China and had been proven to have high Pb tolerance, was inoculated onto the roots of maize(Zea mays L.) seedlings to study the effect of DSE on plant growth, photosynthesis,and the translocation and accumulation of Pb in plant under stress of different Pb concentrations. The growth indicators(height, basal diameter, root length, and biomass) of maize were detected. Chlorophyll content, photosynthetic characteristics(net photosynthetic rate, transpiration rate, stomatal conductance, and intercellular CO_2 concentration), and chlorophyll fluorescence parameters in leaves of the inoculated and non-inoculated maize were also determined. Inoculation with G. cylindrosporus significantly increased height,basal diameter, root length, and biomass of maize seedlings under Pb stress. Colonization of G. cylindrosporus improved the efficiency of photosynthesis and altered the translocation and accumulation of Pb in the plants. Although inoculation with G. cylindrosporus increased Pb accumulation in host plants in comparison to non-inoculated plants, the translocation factor of Pb in plant body was significantly decreased. The results indicated that Pb was accumulated mainly in the root system of maize and the phytotoxicity of Pb to the aerial part of the plant was alleviated. The improvement of efficiency of photosynthesis and the decrease of translocation factor of Pb, caused by DSE fungal colonization, were efficient strategies to improve Pb tolerance of host plants.BAN Yihui XU Zhouying YANG Yurong ZHANG Haihan CHEN Hui TANG Ming 2017Pedosphere2017,27,2:16
2Finite-Time Neural Funnel Control for Motor Servo Systems with Unknown Input Constraint显示文摘In this paper, a finite-time neural funnel control(FTNFC) scheme is proposed for motor servo systems with unknown input constraint. To deal with the non-smooth input saturation constraint problem, a smooth non-affine function of the control input signal is employed to approximate the saturation constraint, which is further transformed into an affine form according to the mean-value theorem. A fast terminal sliding mode manifold is constructed by using a novel funnel error variable to force the tracking error falling into a prescribe boundary within a finite time. Then, a simple sigmoid neural network is utilized to approximate the unknown system nonlinearity including the saturation.Different from the prescribed performance control(PPC), the proposed finite-time neural funnel control avoids using the inverse transformed function in the controller design, and could guarantee the prescribed tracking performance without knowing the saturation bounds in prior. The effectiveness and superior performance of the proposed method are verified by comparative simulation results.CHEN Qiang TANG Xiaoqing NAN Yurong REN Xuemei 2017Journal of Systems Science & Complexity2017,30,3:9
3The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability.Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding 2022Molecular Plant2022,15,5:6
4Mechanical properties and finite element analysis of walnut under different cracking parts显示文摘In order to reduce mechanical damage and improve extraction quality of walnut kernel during walnut cracking,the Wen-185 walnut cultivar was selected as the research object,and the mechanical properties of walnut under different cracking parts were assessed by combining compression tests and finite element analysis(FEA)method.The compression test results showed that the relationships between rupture force and deformation of walnut were nonlinear,and the cracking process of shell mainly consisted of three stages(elastic stage,plastic stage and composite elastic-plastic stage).The best method to crack walnut was the spherical compression,and the peak value of rupture force and corresponding deformation were 211.83 N and 1.68 mm,respectively.In condition of spherical compression,the shell-breaking rate,first-grade kernel rate and whole kernel rate were(91.67±2.89)%,(88.33±2.89)%,(80.00±5.00)%,respectively.The FEA results indicated that spherical compression was also the suitable way to rupture walnut,which resulted in the obvious propagation trends of shell cracks and further a better integrity of extracting walnut kernel.Therefore,the spherical contact form between walnut and cracking parts may be considered to design the structural shape of key components of walnut cracking machines,which was consistent with the analysis of compression test results.The comparison between experiment results and FEA results showed that the established FEA model can be used to analyze the mechanical properties of walnut.The research results can provide references for the structural design and optimization of key components of cracking machines for walnut or other nut crops.Hong Zhang Liuyang Shen Haipeng Lan Yong Li Yang Liu Yurong Tang Wen Li 2018International Journal of Agricultural and Biological Engineering2018,11,6:2

9Solution-processed,flexible and broadband photodetector based on CsPbBr_(3)/PbSe quantum dot heterostructures显示文摘Due to their promising applications in foldable displays,optical communication equipment and environmental monitoring systems,flexible and broadband optoelectronic devices have gained extensive attention in recent years.Here,a flexible and broadband photodetector based on CsPbBr_(3)/PbSe quantum dot(QD) heterostructures is firstly presented.The integrated QD heterostructures possess consecutive detection range from ultraviolet(UV) to long-wave length infrared(LW-IR) regions with efficient light absorption and chemical stability,in comparison with the pristine PbSe QDs.Systematic material characterizations reveal the improved exciton dissociation,carrier transport and carrier lifetime of the QD heterostructures.Flexible photodetector Ag/CsPbBr_(3)/PbSe/Ag demonstrate a high responsivity of 7.17 A/W with a specific detectivity of 8.97 × 10^(12) Jones under 25 μW/cm^(2) 365 nm illumination at 5 V.Furthermore,it could maintain 91.2 %(or 94.9 %) of its initial performance even after bending for thousands of times(or exposing in ambient air for 4 weeks).More importantly,its re s ponse time is shortened more than three orders of magnitude as that of pristine PbSe QDs-based photodetectors.Therefore,it provides a feasible and promising method for the next-generation high-performance broadband photodetectors via constructing heterostructures of various QDs.Jinming Hu Shengyi Yang Zhenheng Zhang Hailong Li Chandrasekar Perumal Veeramalai Muhammad Sulaman Muhammad Imran Saleem Yi Tang Yurong Jiang Libin Tang Bingsuo Zou 2021Journal of Materials Science & Technology2021,,9:1
10CsPbI nanorods as the interfacial layer for high-performance,all-solution-processed self-powered photodetectors显示文摘Heterojunction is regarded as a crucial step toward realizing high-performance devices,particularly,forming gradient energy band between heterojunctions benefits self-powered photodetectors.Therefore,in this paper,the synthesis of CsPbI3 nanorods(NRs)and its application as the interfacial layer in high-performance,all-solution-processed self-powered photodetectors are presented.For the bilayer photodetector ITO/ZnO(100 nm)/PbS-TBAI(150 nm)/Au,a responsivity of 3.6 A/W with a specific detectivity of 9.8×10^(12)Jones was obtained under 0.1 mW/cm^(2)white light illumination at zero bias(i.e.in self-powered mode).Meanwhile,the photocurrent was enhanced to an On/Off current ratio of 105 at zero bias with an open circuit voltage of 0.53 V for trilayer photodetector ITO/ZnO(100 nm)/PbSTBAI(150 nm)/CsPbI3(250 nm)/Au,in which the CsPbI3 NRs layer works as the interfacial layer.As a result,a specific detectivity of 4.5×10^(13)Jones with a responsivity of 11.12 A/W was obtained under0.1 mW/cm^(2) white light illumination,as well as the rising/decaying time of 0.57 s/0.41 s with excellent stability and reproducibility upto four weeks in air.The enhanced-performance is ascribed to the mismatch bandgap between PbS-TBAI/CsPbI_(3)interface,which can suppress the carrier recombination and provide efficient transport passages for charge carriers.Thus,it provides a feasible and efficient method for high-performance photodetectors.Muhammad Imran Saleem Shangyi Yang Attia Batool Muhammad Sulaman Chandrasekar Perumal Veeramalai Yurong Jiang Yi Tang Yanyan Cui Libin Tang Bingsuo Zou 2021Journal of Materials Science & Technology2021,,16:1

12A review of membrane distillation enhancement via thermal management and molecular transport through nanomaterial-based membranes显示文摘Low-energy,high-efficiency desalination techniques are important because of the critical water-energy nexus.In particular,membrane distillation has great potential to harness low-grade and renewable energy sources.Composite membranes using micro-and nanomaterials have new capabilities and characteristics.This review focuses on the most recent developments and potential capabilities in membrane distillation systems from the perspective of nanomaterial enhancements,thermal management,and water transport.Self-heating nanomaterial membrane distillations using permeable composite membranes with significant photothermal or Joule-heating conversion capabilities enable macroscale thermal management and mitigate temperature polarization effects.Modifying the membrane structure and its interaction with water can accelerate water transport and evaporation,improving distillation at the microscopic level.This is expected to provide directions for the fabrication and manipulation of novel micro-and nanocomposite membranes for distillation processes at various levels,and enhance their applications.HUANG Jian HE YuRong HUI SiYu WANG MingHao TANG TianQi 2023Science China(Technological Sciences)2023,66,6:0
13FGD5 as a novel prognostic biomarker and its association with immune infiltrates in lung adenocarcinoma显示文摘Background:Non-small cell lung cancer(NSCLC)has a poor prognosis with a low 5-year survival rate.Lung adenocarcinoma(LUAD)accounts for 50%.Facio-genital dysplasia-5(FGD5),a member of a subfamily of Rho GTPGDP exchange factors,may be a good molecular biomarker for diagnosis and prognosis.Objective:To explore the clinical application of FGD5,the study was designed to investigate the prognosis value of FGD5 expression and its correlation with immune infiltrates in LUAD patients.Methods:Through the Wilcoxon signed-rank test and logistic regression,the correlation between clinical characteristics and FGD5 expression was analyzed.Kaplan-Meier plotter analysis,Cox regression,and a receiver operating characteristic(ROC)curve were constructed to evaluate the influence of FGD5 on prognosis.The function of FGD5 in lung cancer was analyzed using Gene set enrichment analysis(GSEA)and Single Sample Gene Set Enrichment Analysis(ssGSEA).Results:Compared to normal tissues,FGD5 was downregulated in LUAD.FGD5 may be a potential diagnostic and prognostic biomarker of lung cancer for its association with improved overall survival(OS),progression-free interval(PFI),and disease-specific survival(DSS)in LUAD.Results of functional analysis suggested that FGD5 was involved in the immune response for its association with immune infiltration.Conclusion:FGD5 may be a significant molecular biomarker for diagnosis and prognosis,presenting as an independent prognostic risk factor for LUAD.ZHONGXIANG TANG LILI WANG GUOJUN WU LING QIN YURONG TAN 2023BIOCELL2023,47,11:0
14Recent advances in the translation of drug metabolism and pharmacokinetics science for drug discovery and development显示文摘Drug metabolism and pharmacokinetics(DMPK) is an important branch of pharmaceutical sciences.The nature of ADME(absorption,distribution,metabolism,excretion) and PK(pharmacokinetics) inquiries during drug discovery and development has evolved in recent years from being largely descriptive to seeking a more quantitative and mechanistic understanding of the fate of drug candidates in biological systems.Tremendous progress has been made in the past decade,not only in the characterization of physiochemical properties of drugs that influence their ADME,target organ exposure,and toxicity,but also in the identification of design principles that can minimize drug-drug interaction(DDI) potentials and reduce the attritions.The importance of membrane transporters in drug disposition,efficacy,and safety,as well as the interplay with metabolic processes,has been increasingly recognized.Dramatic increases in investments on new modalities beyond traditional small and large molecule drugs,such as peptides,oligonucleotides,and antibody-drug conjugates,necessitated further innovations in bioanalytical and experimental tools for the characterization of their ADME properties.In this review,we highlight some of the most notable advances in the last decade,and provide future perspectives on potential major breakthroughs and innovations in the translation of DMPK science in various stages of drug discovery and development.Yurong Lai Xiaoyan Chu Li Di Wei Gao Yingying Guo Xingrong Liu Chuang Lu Jialin Mao Hong Shen Huaping Tang Cindy Q.Xia Lei Zhang Xinxin Ding 2022Acta Pharmaceutica Sinica B2022,12,6:0

16Model for estimating the weight-loss ratio of damaged Korla fragrant pears显示文摘To predict the weight-loss ratio of Korla fragrant pears effectively,improve commodity value and study the variation laws of the weight-loss ratio of damaged fragrant pears during storage,this study predicted the weight-loss ratio of fragrant pears by utilizing the generalized regression neural network(GRNN),support vector regression(SVR),partial least squares regression(PLSR)and error back propagation neural network(BPNN).The prediction performances of GRNN,SVR,PLSR and BPNN models were compared comprehensively,and the optimal model was determined.In addition,the optimal prediction model was verified.The results show that weight-loss ratio of fragrant pears increases gradually with the extension of storage time.During storage,the weight-loss ratio of fragrant pears is positively related to the degree of damage.The trained GRNN,SVR,PLSR and BPNN models can be used to predict the weight-loss ratio of fragrant pears.The BPNN model is the most accurate in predicting the weight-loss ratio of damaged fragrant pears(R^(2)=0.9929;RMSE=0.2138).It has also been proved to have good predictive effect in production practice(R^(2)=0.9377,RMSE=0.7138).The research findings can provide references to predict the delivery quality and time of delivery of Korla fragrant pears.Yang Liu Yurong Tang Hong Zhang Hao Niu Haipeng Lan 2024International Journal of Agricultural and Biological Engineering2024,17,1:0
17Construction method of quantitative evaluation model for the maturity of Korla fragrant pear显示文摘The maturity variation laws of Korla fragrant pears were explored for a quantitative evaluation of harvest maturity to solve the reasonable matching between harvest maturity of Korla fragrant pears and market quality demands.Korla fragrant pears from different harvesting periods were chosen as the research objects.Some quality indexes were chosen as the evaluation indexes per industry standards,including hardness,soluble solid content(SSC),single-fruit weight,fruit longitudinal diameter,fruit equatorial diameter,pericarp color parameters(L*,a*,and b*),and titratable acid.Variation data of these quality indexes with accumulated temperature were collected.Scores of several quality indexes were gained through principal component analysis.A mathematical model of scores and accumulated temperatures was constructed.On this basis,a quantitative maturity model of Korla fragrant pears was constructed.Results demonstrate that SSC,single-fruit weight,fruit longitudinal diameter,fruit equatorial diameter,L*,a*,and b*are significantly and positively correlated with the accumulated temperature.Meanwhile,hardness and titratable acid showed significant negative correlations with the accumulated temperature.Relations between scores of principal components and accumulated temperature conform to the Sigmoidal model.The constructed quantitative maturity model of Korla fragrant pears can quantify the maturity of pears.Research conclusions can provide insight into the harvest periods,evaluate Korla fragrant pears’maturity,and lay a theoretical foundation for quantitative research on fruit maturity.Shihui Yu Yurong Tang Haipeng Lan Xiaolong Li Hong Zhang Yong Zeng Hao Niu Xiaozhen Jin Yang Liu 2022International Journal of Agricultural and Biological Engineering2022,15,4:0
18Interstitial nitrogen-induced efficiency alcohol oxidation over heterogeneous N–CoMn_(2)O_(4) catalyst under visible-light显示文摘Developing highly efficient and recyclable photocatalysts through harvesting solar light as energy is crucial to oxidation for industrial implementation,especially for simple transition metal oxidic catalysts without precious/heavy/rare metal dopants.Herein,we like to report the use of nitrogen-doped CoMn_(2)O_(4) oxide(N–CoMn_(2)O_(4))as a heterogeneous catalyst for efficient oxidation of various alcohols such as p/m/o-methyl-substituted aromatic alcohols,p-substituted aromatic alcohols including electron-donating and electron-withdrawing substituents,heterocycle-based alcohols and secondary aromatic alcohols to the corresponding aldehydes/ketones,under visible light(>420 nm)illumination and mild condition of oxygen as oxidant and room temperature.The relation of various Co-based oxides to their catalytic performance was studied.It is shown that the Co^(2+)species in N–CoMn_(2)O_(4),obviously increased by the doping of nitrogen,are acted as catalytic active species coupled with the synergistic effect between Co and Mn species for the enhanced visible-light selective oxidation of alcohols to aldehydes.A plausible catalytic mechanism is proposed basis of control experiments and published studies,which suggests that this oxidation process probably occurs on Co^(2+)þsites via an ionic reactive oxygen species pathway and ^(1)O2 and O2⋅^(-)species are the reactive oxygen species.This simple transition metal oxide-catalyzed aerobic oxidation provides a green alternative for the manufacture of aldehydes/ketones from alcohols.Hongwei Li Yurong Zhang Jun Tang Guozheng Huang Ping Cui Qingping Ke 2023Green Synthesis and Catalysis2023,4,4:0

20Comprehensive evaluation of Korla fragrant pears and optimization of plucking time during the harvest period显示文摘To optimize the harvest of Korla fragrant pears and to provide a theoretical basis for post-harvest processing,a total of 26 basic indices of Korla fragrant pears,including their morphology,quality,and softening age,were investigated.The harvest period ranged from August 22nd to October 6th,samples were collected every 5 d(totally 10 plucking days,indicated as H1-H10).The results indicated that changes in pectin content were the main causes of softening in fragrant pears.The scavenging of free radicals mainly occurred because of the collaborative effects of superoxide dismutase(SOD)and catalase(CAT).In the harvest periods H1-H3,the hardness,titratable acid(TA),chlorophyll content,density,and diameter of the stone cells,as well as the cellulose and hemicellulose content of the Korla fragrant pears were at their highest.During the periods H7-H10,the single-fruit weight,fruit horizontal and vertical diameter,color coordinates L,a*,b*,soluble-solids content(SSC),SOD activity,CAT activity,and water-soluble pectin were higher than in the other plucking periods.The highest vitamin C(VC)content and moderate values for a variety of indicators were observed during H3-H7.Variations in the Korla fragrant pears during H1-H3 mainly manifested through changes in softening-related parameters.During H3-H10,changes in the softening-related,aging-related,color-related,and quality indices had a dominant role.On this basis,some suggestions for the post-harvest processing of fragrant pears have been proposed.Fruit,during H1-H3,are suitable for transportation and storage;during H7-H10 are suitable for fresh-eating and further processing;and during H3-H7,exhibited moderate values for a variety of indicators and had the highest commercial value.This research provides a systematic evaluation of the characteristics of mature Korla fragrant pears during the harvest period and can form the basis for fruit quality control and processing of Korla fragrant pears.Zhentao Wang Yurong Tang Xiaozhen Jin Yang Liu Hong Zhang Hao Niu Haipeng Lan 2022International Journal of Agricultural and Biological Engineering2022,15,3:0
