| 1 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020,3,1: | 22 |
| 2 | Chronic intermittent hypoxia induces cardiac inflammation and dysfunction in a rat obstructive sleep apnea model显示文摘Chronic intermittent hypoxia is considered to play an important role in cardiovascular pathogenesis during the development of obstructive sleep apnea(OSA).We used a well-described OSA rat model induced with simultaneous intermittent hypoxia.Male Sprague Dawley rats were individually placed into plexiglass chambers with air pressure and components were electronically controlled.The rats were exposed to intermittent hypoxia 8 hours daily for 5weeks.The changes of cardiac structure and function were examined by ultrasound.The cardiac pathology,apoptosis,and fibrosis were analyzed by H&E staining,TUNNEL assay,and picosirius staining,respectively.The expression of inflammation and fibrosis marker genes was analyzed by quantitative real-time PCR and Western blot.Chronic intermittent hypoxia/low pressure resulted in significant increase of left ventricular internal diameters(LVIDs),endsystolic volume(ESV),end-diastolic volume(EDV),and blood lactate level and marked reduction in ejection fraction and fractional shortening.Chronic intermittent hypoxia increased TUNNEL-positive myocytes,disrupted normal arrangement of cardiac fibers,and increased Sirius stained collagen fibers.The expression levels of hypoxia induced factor(HIF)-l α,NF-κB,IL-6,and matrix metallopeptidase 2(MMP-2) were significantly increased in the heart of rats exposed to chronic intermittent hypoxia.In conclusion,the left ventricular function was adversely affected by chronic intermittent hypoxia,which is associated with increased expression of HIF-lα and NF-κB signaling molecules and development of cardiac inflammation,apoptosis and fibrosis. | Qin Wei Yeping Bian Fuchao Yu Qiang Zhang Guanghao Zhang Yang Li Songsong Song Xiaomei Ren Jiayi Tong | 2016 | The Journal of Biomedical Research2016,30,6: | 15 |
| 3 | The Assessment of Global Surface Temperature Change from 1850s:The C-LSAT2.0 Ensemble and the CMST-Interim Datasets显示文摘Based on C-LSAT2.0,using high-and low-frequency components reconstruction methods,combined with observation constraint masking,a reconstructed C-LSAT2.0 with 756 ensemble members from the 1850s to 2018 has been developed.These ensemble versions have been merged with the ERSSTv5 ensemble dataset,and an upgraded version of the CMSTInterim dataset with 5°×5°resolution has been developed.The CMST-Interim dataset has significantly improved the coverage rate of global surface temperature data.After reconstruction,the data coverage before 1950 increased from 78%−81%of the original CMST to 81%−89%.The total coverage after 1955 reached about 93%,including more than 98%in the Northern Hemisphere and 81%−89%in the Southern Hemisphere.Through the reconstruction ensemble experiments with different parameters,a good basis is provided for more systematic uncertainty assessment of C-LSAT2.0 and CMSTInterim.In comparison with the original CMST,the global mean surface temperatures are estimated to be cooler in the second half of 19th century and warmer during the 21st century,which shows that the global warming trend is further amplified.The global warming trends are updated from 0.085±0.004℃(10 yr)^(–1)and 0.128±0.006℃(10 yr)^(–1)to 0.089±0.004℃(10 yr)^(–1)and 0.137±0.007℃(10 yr)^(–1),respectively,since the start and the second half of 20th century. | Wenbin SUN Qingxiang LI Boyin HUANG Jiayi CHENG Zhaoyang SONG Haiyan LI Wenjie DONG Panmao ZHAI Phil JONES | 2021 | Advances in Atmospheric Sciences2021,38,5: | 8 |
| 4 | Deep neural network for remote-sensing image interpretation: status and perspectives显示文摘Deep neural networks(D N N s)refer to end-to-end mappings(i.e.from data to information)by stacking a large num ber of filters learned from massive samples.By courtesy of the comprehensive Earth observation platforms and convenient data access,remote-sensing practitioners are dealing with very large and ever-growing data volumes,which call for fast and transferrable machine-learning technologies for the large-scale geospatial information mining[l].While some progress has been made,research in deep-learning-based remote-sensing image interpretation is still in its infancy,mainly subject to insufficient annotation samples,high complexity of the model,and lack of in-depth integration between deep learning and remote sensing.Construction of diverse and representative remote-sensing benchmark datasets,further investigation on task-driven deep learning(i.e.the integration of deep learning and remotesensing physical mechanisms)and the efforts towards promoting the practicality of the networks should be considered in the agenda.In this context. | Jiayi Li Xin Huang Jianya Gong | 2019 | National Science Review2019,6,6: | 7 |
| 5 | Battery Separators Functionalized with Edge-Rich MoS2/C Hollow Microspheres for the Uniform Deposition of Li2S in High-Performance Lithium-Sulfur Batteries显示文摘As promising energy storage systems,lithium-sulfur(Li-S)batteries have attracted significant attention because of their ultra-high energy densities.However,Li-S battery suffers problems related to the complex phase conversion that occurs during the charge-discharge process,particularly the deposition of solid Li2S from the liquid-phase polysulfides,which greatly limits its practical application.In this paper,edge-rich MoS2/C hollow microspheres(Edg-MoS2/C HMs)were designed and used to functionalize separator for Li-S battery,resulting in the uniform deposition of Li2S.The microspheres were fabricated through the facile hydrothermal treatment of MoO3-aniline nanowires and a subsequent carbonization process.The obtained Edg-MoS2/C HMs have a strong chemical absorption capability and high density of Li2S binding sites,and exhibit excellent electrocatalytic performance and can effectively hinder the polysulfide shuttle effect and guide the uniform nucleation and growth of Li2S.Furthermore,we demonstrate that the Edg-MoS2/C HMs can effectively regulate the deposition of Li2S and significantly improve the reversibility of the phase conversion of the active sulfur species,especially at high sulfur loadings and high C-rates.As a result,a cell containing a separator functionalized with Edg-MoS2/C HMs exhibited an initial discharge capacity of 935 mAh g-1 at 1.0 C and maintained a capacity of 494 mAh g-1 after 1000 cycles with a sulfur loading of 1.7 mg cm-2.Impressively,at a high sulfur loading of 6.1 mg cm-2 and high rate of 0.5 C,the cell still delivered a high reversible discharge capacity of 478 mAh g-1 after 300 cycles.This work provides fresh insights into energy storage systems related to complex phase conversions. | Nan Zheng Guangyu Jiang Xiao Chen Jiayi Mao Nan Jiang Yongsheng Li | 2019 | Nano-Micro Letters2019,11,3: | 7 |
| 6 | Recent progress and perspective of electrochemical CO_(2) reduction towards C_(2)-C_(5) products over non-precious metal heterogeneous electrocatalysts显示文摘Electroreduction of carbon dioxide(CO_(2)ER)into value-added chemical compounds has presented as a promising route for renewable carbon cycle,which alleviates global warming concern.Compared with traditional C1 products,high-value multicarbon products converted from atmospheric CO_(2) via CO_(2)ER have attracted dramatic interest due to their significant economic efficiency,however desired catalytic selectivity of multicarbon products is difficult to achieve because of the high thermodynamic barriers and complex reaction pathways.To replace currently used precious-metal based catalysts,developing highly efficient and precious-metal-free CO_(2)ER catalysts based on earth abundant elements is the top priority to meet the requirements of industrialization.Although certain progress has been made,there are still few systematic reports on the non-precious metal heterogeneous(NPMH)CO_(2)ER electrocatalysts for efficient conversion of CO_(2) to multicarbon products.Herein,we summarize the latest research advances in recent developments of NPMH electrocatalysts,including nanostructured Cu,Cu-based bimetallic catalysts,Cu-based complexes,and carbon-based Cu-free catalysts for electroreduction of CO_(2) into high-value multicarbon products.The corresponding CO_(2)ER performances are discussed in the order of the types of multicarbon products,specifically for ethanol(C2H5OH),ethylene(C2H4),ethane(C2H6),acetic acid(CH3COOH),propanol(C3H7OH),and other O^(2+)products with a special attention paid to understand the structure-activity relationship.Moreover,key strategies and characterization techniques for catalytic mechanism insights,and unsolved issues and future trends for enhancing the CO_(2)ER performance of NPMH electrocatalysts are highlighted,which provides a constructive guidance on the development of CO_(2)ER electrocatalysts with high activity and selectivity for multicarbon products. | Jiayi Chen Tingting Wang Zhongjian Li Bin Yang Qinghua Zhang Lecheng Lei Pingyun Feng Yang Hou | 2021 | Nano Research2021,14,9: | 7 |
| 7 | Regulation of the inflammatory cycle by a controllable release hydrogel for eliminating postoperative inflammation after discectomy显示文摘Surgery is the final choice for most patients with intervertebral disc degeneration(IDD).Operation-caused trauma will cause inflammation in the intervertebral disc.Serious inflammation will cause tissue defects and induce tissue degeneration,IDD recurrence and the occurrence of other diseases.Therefore,we proposed a scheme to treat recurrence after discectomy by inhibiting inflammation with an aspirin(ASP)-loaded hydrogel to restore the mechanical stability of the spine and relieve local inflammation.ASP-liposomes(ASP-Lips)were incorporated into a photocrosslinkable gelatin-methacryloyl(GelMA)via mixing.This material can effectively alleviate inflammation by inhibiting the release of high mobility group box 1(HMGB1)from the nucleus to the cytoplasm.We further assessed the expression of inflammatory cytokines,such as interleukin 6(IL-6)and tumor necrosis factor-α(TNF-α),and degeneration-related factors,such as type II collagen(COL-2),Aggrecan,matrix metallopeptidases-3(MMP-3),MMP-13,a disintegrin and metalloproteinase with thrombospondin motifs-4(ADAMTS-4)and ADAMTS-5 in rat nucleus pulpous cells.The level of IDD was analyzed through H&E,safranin-O staining and immunohistochemistry in rabbit samples.In vitro,we found that ASP-Lip@GelMA treatment significantly decreased inflammatory cytokines,MMP-3 and-13,and ADAMTS-4 and-5 and up-regulated COL-2 and Aggrecan via the inhibited release of HMGB-1 from the nucleus.In vivo,ASP-Lip@GelMA can effectively inhibit inflammation of local tissue after disc surgery and fill local tissue defects.This composite hydrogel system is a promising way to treat the recurrence of IDD after surgery without persistent complications. | Yu Liu Jiacheng Du Peng Peng Ruoyu Cheng Jiayi Lin Congxin Xu Huilin Yang Wenguo Cui Haiqing Mao Yuling Li Dechun Geng | 2021 | Bioactive Materials2021,6,1: | 6 |
| 8 | Response regimes of nonlinear energy harvesters with a resistorinductor resonant circuit by complexification-averaging method显示文摘In this paper, the steady-state response regimes of nonlinear energy harvesters with a resistor-inductor resonant circuit are theoretically investigated. The complexification averaging(CA) method is used to theoretically analyze the energy harvesting performance and reduce the motion equations into a set of first-order differential equations. The amplitudes and phases of both the response displacement and the output voltage are derived, and the corresponding stability conditions are determined. The response regimes are studied with the variation of nonlinear stiffness coefficients and coupling parameters, which are verified by the time domain analysis. The frequency island phenomenon is found and analyzed. Additionally, the backbone curve for deducing the extreme vibration frequency and amplitude is derived. Simultaneously, the analytical expressions of the switching points(critical amplitude and frequency) to identify the hardening and softening properties are established. Accordingly, a criterion is given to determine the occurrence of the jump phenomenon, and its effectiveness is verified. Overall, this paper presents an in-depth theoretical analysis of nonlinear energy harvesters with a resistor-inductor resonant circuit. It presents the theoretical framework and guidance for more extensive evaluations and understanding the theoretical analysis of nonlinear energy harvesters with external circuits. | HUANG DongMei CHEN JiaYi ZHOU ShengXi FANG XueLai LI Wei | 2021 | Science China(Technological Sciences)2021,64,6: | 6 |
| 9 | A new distinct geminivirus causes soybean stay-green disease显示文摘Dear Editor,Plant viruses make up almost half of the plant disease-causing pathogens,affecting crop yields and the global economy(Savary et al.,2019).Soybean(Glycine max)is one of the most valuable legume crops in the world,supplying 25%of the global edible oil and two-thirds of the global concentrated protein for livestock feeding.Recently,the outbreak of soybean stay-green syndrome with delayed leaf senescence(stay-green),flat pods,and increased number of abnormal seeds has swept the soybean production in the Huang-Huai-Hai region of China,resulting in huge yield losses(Xu et al.,2019).This disease has become an epidemic and prominent problem in soybean production and is still expanding its geography,including North America,posing a serious threat to soybean production(Harbach et al.,2016;Zhang et al.,2016;Li et al.,2019).However,the cause of soybean stay-green syndrome remains obscure. | Ruixiang Cheng Ruoxin Mei Rong Yan Hongyu Chen Dan Miao Lina Cai Jiayi Fan Gairu Li Ran Xu Weiguo Lu Yu Gao Wenwu Ye Shuo Su Tianfu Han Junyi Gai Yuanchao Wang Xiaorong Tao Yi Xu | 2022 | Molecular Plant2022,15,6: | 6 |

| 11 | RING finger protein RGLG1 and RGLG2 negatively modulate MAPKKK18 mediated drought stress tolerance in Arabidopsis显示文摘Mitogen activated protein kinase kinase kinase 18(MAPKKK18)mediated signaling cascade plays important roles in Arabidopsis drought stress tolerance.However,the post-translational modulation patterns of MAPKKK18 are not characterized.In this study,we found that the protein level of MAPKKK18 was tightly controlled by the 26 S proteasome.Ubiquitin ligases RGLG1 and RGLG2 ubiquitinated MAPKKK18 at lysine residue K32 and K154,and promoted its degradation.Deletion of RGLG1 and RGLG2 stabilized MAPKKK18 and further enhanced the drought stress tolerance of MAPKKK18-overexpression plants.Our data demonstrate that RGLG1 and RGLG2 negatively regulate MAPKKK18-mediated drought stress tolerance in Arabidopsis. | Jiayi Yu Lu Kang Yuanyuan Li Changai Wu Chengchao Zheng Pei Liu Jinguang Huang | 2021 | Journal of Integrative Plant Biology2021,63,3: | 4 |

| 13 | Bispecific prodrug nanoparticles circumventing multiple immune resistance mechanisms for promoting cancer immunotherapy显示文摘Cancer immunotherapy is impaired by the intrinsic and adaptive immune resistance.Herein,a bispecific prodrug nanoparticle was engineered for circumventing immune evasion of the tumor cells by targeting multiple immune resistance mechanisms.A disulfide bond-linked bispecific prodrug of NLG919 and JQ1(namely NJ) was synthesized and self-assembled into a prodrug nanoparticle,which was subsequently coated with a photosensitizer-modified and tumor acidity-activatable diblock copolymer PHP for tumor-specific delivery of NJ.Upon tumor accumulation via passive tumor targeting,the polymeric shell was detached for facilitating intracellular uptake of the bispecific prodrug.NJ was then activated inside the tumor cells for releasing JQ1 and NLG919 via glutathione-mediated cleavage of the disulfide bond.JQ1 is a bromodomain-containing protein 4 inhibitor for abolishing interferon gamma-triggered expression of programmed death ligand 1.In contrast,NLG919 suppresses indoleamine-2,3-dioxygenase 1-mediated tryptophan consumption in the tumor microenvironment,which thus restores robust antitumor immune responses.Photodynamic therapy(PDT) was performed to elicit antitumor immunogenicity by triggering immunogenic cell death of the tumor cells.The combination of PDT and the bispecific prodrug nanoparticle might represent a novel strategy for blockading multiple immune evasion pathways and improving cancer immunotherapy. | Jiayi Ye Bo Hou Fangmin Chen Shunan Zhang Muya Xiong Tianliang Li Yechun Xu Zhiai Xu Haijun Yu | 2022 | Acta Pharmaceutica Sinica B2022,12,6: | 4 |
| 14 | TCMSTD 1.0: a systematic analysis of the traditional Chinese medicine system toxicology database显示文摘Dear Editor,The safety and modernization of traditional Chinese medicine (TCM) are significant concerns for users’ lives and health. Recently, the adverse effects caused by TCM and traditional nontoxic TCM have been frequently reported (Joo et al., 2020;Liu et al., 2021). As the safety of TCM continues to attract widespread attention, many researchers have been investigating the toxicity of TCM in regard to the toxic ingredients, effects, mechanisms, and detoxification strategies in TCM (Figure S1 in Supporting Information). Although some TCMs cause toxic reactions, they also play key roles in treating certain unignorable diseases (Fang et al., 2022).Therefore, toxicity research is crucial and urgently needed to develop and safely use TCM. | Lili Song Wenxiu Qian Hongqing Yin Yu Sun Xiuyan Sun Guohui Li Junjie He Yanxue Zheng Yue Zhang Jiayi Wang Yubo Li | 2023 | Science China(Life Sciences)2023,66,9: | 3 |
| 15 | The next detectors for gravitational wave astronomy显示文摘This paper focuses on the next detectors for gravitational wave astronomy which will be required after the current ground based detectors have completed their initial observations, and probably achieved the first direct detection of gravitational waves. The next detectors will need to have greater sensitivity, while also enabling the world array of detectors to have improved angular resolution to allow localisation of signal sources. Sect. 1 of this paper begins by reviewing proposals for the next ground based detectors,and presents an analysis of the sensitivity of an 8 km armlength detector, which is proposed as a safe and cost-effective means to attain a 4-fold improvement in sensitivity. The scientific benefits of creating a pair of such detectors in China and Australia is emphasised. Sect. 2 of this paper discusses the high performance suspension systems for test masses that will be an essential component for future detectors, while sect. 3 discusses solutions to the problem of Newtonian noise which arise from fluctuations in gravity gradient forces acting on test masses. Such gravitational perturbations cannot be shielded, and set limits to low frequency sensitivity unless measured and suppressed. Sects. 4 and 5 address critical operational technologies that will be ongoing issues in future detectors. Sect. 4 addresses the design of thermal compensation systems needed in all high optical power interferometers operating at room temperature. Parametric instability control is addressed in sect. 5. Only recently proven to occur in Advanced LIGO, parametric instability phenomenon brings both risks and opportunities for future detectors. The path to future enhancements of detectors will come from quantum measurement technologies. Sect. 6 focuses on the use of optomechanical devices for obtaining enhanced sensitivity, while sect. 7 reviews a range of quantum measurement options. | BLAIR David JU Li ZHAO ChunNong WEN LinQing MIAO HaiXing CAI RongGen GAO JiangRui LIN XueChun LIU Dong WU Ling-An ZHU ZongHong HAMMOND Giles PAIK Ho Jung FAFONE Viviana ROCCHI Alessio BLAIR Carl MA YiQiu QIN JiaYi PAGE Michael | 2015 | Science China(Physics,Mechanics & Astronomy)2015,58,12: | 3 |
| 16 | STAT3-Decoy ODN Inhibits Cytokine Autocrine of Murine Tumor Cells显示文摘Tumor cells usually secrete soluble factors to improve their proliferation via autocrine network or to escape from immune surveillance by inhibiting antitumor immunity,among these factors IL-10 and IL-6 play more important roles. Since both cytokines' signal transductions are mediated through the STAT3 pathway,STAT3 becomes an attractive target for tumor therapy. In present study,STAT3 of murine tumor cell lines B16 and MCA-38 was constitutively activated. After treatment with STAT3-decoy ODN,the proliferation of these tumor cells was inhibited and the transcription of IL-10 or IL-6 in tumor cells was down-regulated. These results suggested that STAT3 is a good target candidate,and STAT3-decoy ODN may possibly be used as a strategy for breaking both tumor autocrine network and tumor immunotolerance. | Xi Liu Jiayi Li Jian Zhang | 2007 | Cellular & Molecular Immunology2007,4,4: | 3 |
| 17 | Fusobacterium nucleatum enhances the efficacy of PD-L1 blockade in colorectal cancer显示文摘Given that only a subset of patients with colorectal cancer(CRC)benefit from immune checkpoint therapy,efforts are ongoing to identify markers that predict immunotherapeutic response.Increasing evidence suggests that microbes influence the efficacy of cancer therapies.Fusobacterium nucleatum induces different immune responses in CRC with different microsatellite-instability(MSI)statuses.Here,we investigated the effect of F.nucleatum on anti-PD-L1 therapy in CRC.We found that high F.nucleatum levels correlate with improved therapeutic responses to PD-1 blockade in patients with CRC.Additionally,F.nucleatum enhanced the antitumor effects of PD-L1 blockade on CRC in mice and prolonged survival.Combining F.nucleatum supplementation with immunotherapy rescued the therapeutic effects of PD-L1 blockade.Furthermore,F.nucleatum induced PD-L1 expression by activating STING signaling and increased the accumulation of interferon-gamma(IFN-γ)^(+)CD8^(+)tumor-infiltrating lymphocytes(TILs)during treatment with PD-L1 blockade,thereby augmenting tumor sensitivity to PD-L1 blockade.Finally,patient-derived organoid models demonstrated that increased F.nucleatum levels correlated with an improved therapeutic response to PD-L1 blockade.These findings suggest that F.nucleatum may modulate immune checkpoint therapy for CRC. | Yaohui Gao Dexi Bi Ruting Xie Man Li Jing Guo Hu Liu Xianling Guo Juemin Fang Tingting Ding Huiyuan Zhu Yuan Cao Meichun Xing Jiayi Zheng Qing Xu Qian Xu Qing Wei Huanlong Qin | 2021 | Signal Transduction and Targeted Therapy2021,6,12: | 3 |
| 18 | A Feed-Forward Wavelet Neural Network Adaptive Observer-Based Fault Detection Technique for Spacecraft Attitude Control Systems显示文摘This paper presents a novel neural network-based fault detection technique applicable to a class of nonlinear systems. The adaptive observer was designed for fault detection based on a single hidden layer feed-forward wavelet neural network. In order to guarantee network convergence, the network weights are updated according to a modified back-propagation algorithm, and the Lyapunov function is introduced to ensure stability.The proposed fault detection scheme was tested on the actuators of a typical spacecraft attitude control system, and the results demonstrated the effectiveness and feasibility of the proposed observer in detecting nonlinear system failure. | WEN Xin WANG Jiayi LI Xin | 2018 | Chinese Journal of Electronics2018,27,1: | 3 |
| 19 | Exogenous SA Initiated Defense Response and Multi-signaling Pathway in Tetraploid Potato SD20显示文摘Salicylic acid(SA) is an important signaling substance that plays an important role in plant growth, development and disease resistance.In order to further understand the role of the SA pathway in potato disease resistance and identify SA signaling key genes, gene expression profiling of the late blight resistance genotype SD20 was performed under exogenous SA application. A total of 28 572 unigenes were assembled,of which 4 564 were differentially expressed. Analysis of differentially expressed genes(DEGs) showed that multiple signaling pathways such as SA, jasmonic acid, ethylene, abscisic acid, auxin, and brassinolide were involved in response to exogenous SA. Many plant defense signalrelated genes involved in protein serine/threonine kinase activity and plant-pathogen interaction, were significantly enriched. These were consistent with the interaction results of SD20 and Phytophthora infestans in our previous study, indicating that exogenous SA stimulated the resistance response and initiated a similar defense pathway compared to pathogen infection in SD20, which confirmed crosstalk of the SA signaling pathway with a pathogen-induced disease resistance signal pathway in plant. Moreover, transcriptome analysis revealed that ROS1 was positively regulated by SA in potato for the first time. SA-induced gene expression profiling provides insight into SA signaling and its mechanisms in disease defense systems. | Jiayi Zheng Yu Yang Xiao Guo Liping Jin Xingyao Xiong Xiaohui Yang Guangcun Li | 2020 | Horticultural Plant Journal2020,6,2: | 3 |
| 20 | Mapping and analyzing the local climate zones in China’s 32 major cities using Landsat imagery based on a novel convolutional neural network显示文摘The Local Climate Zone(LCZ)scheme provides researchers with a standard method to monitor the Urban Heat Island(UHI)effect and conduct temperature studies.How to generate reliable LCZ maps has therefore become a research focus.In recent years,researchers have attempted to use Landsat imagery to delineate LCZs and generate maps worldwide based on the World Urban Database and Access Portal Tools(WUDAPT).However,the mapping results obtained by the WUDAPT method are not satisfactory.In this paper,to generate more accurate LCZ maps,we propose a novel Convolutional Neural Network(CNN)model(namely,LCZ-CNN),which is designed to cope with the issues of LCZ classification using Landsat imagery.Furthermore,in this study,we applied the LCZ-CNN model to generate LCZ mapping results for China’s 32 major cities distributed in various climatic zones,achieving a significantly better accuracy than the traditional classification strategies and a satisfactory computational efficiency.The pro-posed LCZ-CNN model achieved satisfactory classification accuracies in all 32 cities,and the Overall Accuracies(OAs)of more than half of the cities were higher than 80%.We also designed a series of experiments to comprehensively analyze the proposed LCZ-CNN model,with regard to the transferability of the network and the effectiveness of multiseasonal information.It was found that the first convolutional stage,corresponding to low-level features,shows better transferability than the second and third convolutional stages,which extract high-level and more image-or task-oriented features.It was also confirmed that the multi-seasonal information can improve the accuracy of LCZ classifica-tion.The thermal characteristics of the different LCZ classes were also analyzed based on the mapping results for China’s 32 major cities,and the experimental results confirmed the close relationship between the LCZ classes and the magnitude of the Land Surface Temperature(LST). | Xin Huang Anling Liu Jiayi Li | 2021 | Geo-Spatial Information Science2021,24,4: | 2 |
