| 1 | Progresses on microwave remote sensing of land surface parameters显示文摘Highly accurate observations at various scales on the land surface are urgently needed for the studies of many areas,such as hydrology,meteorology,and agriculture.With the rapid development of remote sensing techniques,remote sensing has had the capacity of monitoring many factors of the Earth's land surface.Especially,the space-borne microwave remote sensing systems have been widely used in the quantitative monitoring of global snow,soil moisture,and vegetation parameters with their all-weather,all-time observation capabilities and their sensitivities to the characteristics of land surface factors.Based on the electromagnetic theories and microwave radiative transfer equations,researchers have achieved great successes in the microwave remote sensing studies for different sensors in recent years.This article has systematically reviewed the progresses on five research areas including microwave theoretical modeling,microwave inversion on soil moisture,snow,vegetation and land surface temperatures.Through the further enrichment of remote sensing datasets and the development of remote sensing theories and inversion techniques,remote sensing including microwave remote sensing will play a more important role in the studies and applications of the Earth systems. | SHI JianCheng DU Yang DU JinYang JIANG LingMei CHAI LinNa MAO KeBiao XU Peng NI WenJian XIONG Chuan LIU Qiang LIU ChenZhou GUO Peng CUI Qian LI YunQing CHEN Jing WANG AnQi LUO HeJia WANG YinHui | 2012 | Science China Earth Sciences2012，55，7： | 24 |

| 3 | Experimental Study on Wear and Spalling Behaviors of Railway Wheel显示文摘The current researches of the wear and spalling behaviors of wheel/rail materials focus on the field investigation rather than the mechanism.However,it is necessary and significant for clarifying the mechanism and relationship between the wear and spalling damage of railway wheel to test and reproduce the wheel damages in laboratory.The objective of this paper is to investigate the wear and spalling damage behaviors of railway wheel using a JD-1 wheel/rail simulation facility,which consists of a small wheel serving as rolling stock wheel,and a larger wheel serving as rail.The damage process of wheel roller is explored in terms of the creep ratio,axle load,and carbon content by means of various microscopic examinations.The experimental results show that the wear volume growth of wheel roller is proved to be proportional to the increase of the creep ratio and normal load between simulating wheel and rail.The increase of carbon content of wheel material causes a linear reduction in the wear volume.The microscopic examinations indicate that the rolling wear mechanism transfers from abrasive wear to adhesive and fatigue wear with an increase of tangential friction force,which results in the initiation of fatigue crack,and then aggravates spalling damage on the wheel roller surface.The surface hardness of material depends strongly upon its carbon content.The decrease of the carbon content of wheel material may alleviate spalling damage,but can cause a significant growth in the wear volume of wheel roller.Therefore,there is a competitive relationship between the wear and spalling damage of wheel material.This research proposes an important measure for alleviating or preventing the wear and spalling damage of railway wheel material. | WANG Wenjian GUO Jun LIU Qiyue | 2013 | Chinese Journal of Mechanical Engineering2013，26，6： | 7 |
| 4 | Sodium cantharidinate,a novel anti-pancreatic cancer agent that activates functional p53显示文摘Despite the use of many types of chemotherapies for pancreatic cancer, optimal efficacy has not been obtained so far. Pancreatic cancer shows a high incidence of TP53 mutations, inactivating its tumor suppressor activity. In this study, we identified sodium cantharidinate as a novel, potential anti-pancreatic cancer agent that activates p53 function. Sodium cantharidinate reduced the viability of pancreatic cancer cells, including the human primary pancreatic cancer cells, PANC-1, As PC-1, SW1990 and BXPC-3, in a dose-dependent manner. Sodium cantharidinate induced apoptosis and DNA damage of pancreatic cancer cells. Furthermore, proteome-wide sequencing analysis detected a marked perturbation in p53 signaling pathway on PANC-1 cells upon sodium cantharidinate. Consistent with the previous results, sodium cantharidinate treatment decreased Bcl-2 and mitochondrial cytochrome-c protein expression, as well as phosphorylation of MDM2;meanwhile, it increased the levels of cleaved-caspase-3,cleaved-caspase-9, cleaved-PARP, Bax, and phosphorylated p53, thus inducing the apoptosis of pancreatic cancer cells. The p53-activating effect of sodium cantharidinate was strongly abrogated by treatment with TP53-targeting sh RNA. Moreover, sodium cantharidinate inhibited neoplasm growth via the JAK2-STAT3 pathway, which was inhibited by sh RNA-TP53 and triggered by combination with gemcitabine. Combination therapy indicated that sodium cantharidinate and gemcitabine synergistically reduced ex vivo and in vivo growth of pancreatic neoplasm. Further docking studies revealed the different binding fates of sodium cantharidinate to activate wild-type p53 function. Thus, sodium cantharidinate could be a potential agent with promising anti-pancreatic cancer efficacy. | Xiaoxiao Liu Li Zhang Pyone Myat Thu Wenjian Min Peng Yang Ji Li Ping Li Xiaojun Xu | 2021 | Science China(Life Sciences)2021，64，8： | 5 |
| 5 | Tubeimoside-1 induces TFEB-dependent lysosomal degradation of PD-L1 and promotes antitumor immunity by targeting mTOR显示文摘Programmed cell death ligand 1(PD-L1)/programmed cell death protein 1(PD-1)cascade is an effective therapeutic target for immune checkpoint blockade(ICB)therapy.Targeting PD-L1/PD-1 axis by small-molecule drug is an attractive approach to enhance antitumor immunity.Using flow cytometry-based assay,we identify tubeimoside-1(TBM-1)as a promising antitumor immune modulator that negatively regulates PD-L1 level.TBM-1 disrupts PD-1/PD-L1 interaction and enhances the cytotoxicity of T cells toward cancer cells through decreasing the abundance of PD-L1.Furthermore,TBM-1 exerts its antitumor effect in mice bearing Lewis lung carcinoma(LLC)and B16 melanoma tumor xenograft via activating tumor-infiltrating T-cell immunity.Mechanistically,TBM-1 triggers PD-L1 lysosomal degradation in a TFEB-dependent,autophagy-independent pathway.TBM-1 selectively binds to the mammalian target of rapamycin(m TOR)kinase and suppresses the activation of m TORC1,leading to the nuclear translocation of TFEB and lysosome biogenesis.Moreover,the combination of TBM-1 and anti-CTLA-4 effectively enhances antitumor T-cell immunity and reduces immunosuppressive infiltration of myeloid-derived suppressor cells(MDSCs)and regulatory T(Treg)cells.Our findings reveal a previously unrecognized antitumor mechanism of TBM-1 and represent an alternative ICB therapeutic strategy to enhance the efficacy of cancer immunotherapy. | Xiaojia Liu Mingxiao Yin Jingwen Dong Genxiang Mao Wenjian Min Zean Kuang Peng Yang Lu Liu Na Zhang Hongbin Deng | 2021 | Acta Pharmaceutica Sinica B2021，11，10： | 5 |
| 6 | Inactivation of TFEB and NF-kB by marchantin M alleviates the chemotherapy-driven pro-tumorigenic senescent secretion显示文摘It is critical to regulate the senescence-associated secretory phenotype(SASP) due to its effect on promoting malignant phenotypes and limiting the efficiency of cancer therapy. In this study, we demonstrated that marchantin M(Mar-M, a naturally occurring bisbibenzyl) suppressed proinflammatory SASP components which were elevated in chemotherapy-resistant cells. Mar-M treatment attenuated the pro-tumorigenic effects of SASP and enhanced survival in drug-resistant mouse models.No toxicity was detected on normal fibroblast cells or in animals following this treatment. Inactivation of transcription factor EB(TFEB) and nuclear factor-k B(NF-k B) by Mar-M significantly accounted for its suppression on the components of SASP. Furthermore, inhibition of SASP by Mar-M contributed to a synergistic effect during co-treatment with doxorubicin to lower toxicity and enhance antitumor efficacy. Thus, chemotherapy-driven pro-inflammatory activity, seen to contribute to drug-resistance, is an important target for Mar-M. By decreasing SASP, Mar-M may be a potential approach to overcome tumor malignancy. | Huanmin Niu Lilin Qian Bin Sun Wenjian Liu Fang Wang Qian Wang Xiaotian Ji Yanhai Luo Effat Un Nesa Hongxiang Lou Huiqing Yuan | 2019 | Acta Pharmaceutica Sinica B2019，9，5： | 4 |
| 7 | Intrinsically Stretchable Organic-Tribotronic-Transistor for Tactile Sensing显示文摘Stretchable electronics are of great significance for the development of the next-generation smart interactive systems.Here,we propose an intrinsically stretchable organic tribotronic transistor(SOTT)without a top gate electrode,which is composed of a stretchable substrate,silver nanowire electrodes,semiconductor blends,and a nonpolar elastomer dielectric.The drain-source current of the SOTT can be modulated by external contact electrification with the dielectric layer.Under 0-50%stretching both parallel and perpendicular to the channel directions,the SOTT retains great output performance.After being stretched to 50%for thousands of cycles,the SOTT can survive with excellent stability.Moreover,the SOTT can be conformably attached to the human hand,which can be used for tactile signal perception in human-machine interaction and for controlling smart home devices and robots.This work has realized a stretchable tribotronic transistor as the tactile sensor for smart interaction,which has extended the application of tribotronics in the human-machine interface,wearable electronics,and robotics. | Junqing Zhao Tianzhao Bu Xiaohan Zhang Yaokun Pang Wenjian Li Zhi Zhang Guoxu Liu Zhong Lin Wang Chi Zhang | 2020 | Research2020，，1： | 4 |
| 8 | Platelet-mediated adhesion facilitates leukocyte sequestration in hypoxia-reoxygenated microvessels显示文摘Leukocyte transendothelial migration and sequestration are two distinct outcomes following leukocyte adhesion to endothelium during ischemia-reperfusion injury, in which platelets may play a pivotal role. In the present study, we established an in vitro hypoxia-reoxygenation model to mimic ischemia-reperfusion injury and found platelet pre-incubation significantly increased leukocyte adhesion to endothelial cells after hyoxia-reoxygenation(over 67%). Blockade of endothelial-cell-expressed adhesion molecules inhibited leukocyte direct adhesion to endothelial cells, while platelet-mediated leukocyte adhesion was suppressed by blockade of platelet-expressed adhesion molecules. Further experiments revealed platelets acted as a bridge to mediate leukocyte adhesion, and platelet-mediated adhesion was the predominant pattern in the presence of platelets. However, platelet pre-incubation significantly suppressed leukocyte transendothelial migration after hypoxia-reoxygenation(over 31%), which could be aggravated by blockade of endothelial-cell-expressed adhesion molecules, but alleviated by blockade of platelet-expressed adhesion molecules. This would indicate that platelet-mediated adhesion disrupted leukocyte transendothelial migration. An in vivo mesenteric ischemia-reperfusion model demonstrated leukocyte transfusion alone caused mild leukocyte adhesion to reperfused vessels and subsequent leukocyte infiltration, while simultaneous leukocyte and platelet transfusion led to massive leukocyte adhesion and sequestration within reperfused microvessels. Our studies revealed platelets enhanced leukocyte adhesion to endothelial cells, but suppressed leukocyte transendothelial migration. Overall, this leads to leukocyte sequestration in hypoxia-reoxygenated microvessels. | Senfeng Zheng Yanting Cao Wenjian Zhang Honglin Liu Jia You Yiqing Yin Jinning Lou Chenghui Li | 2016 | Science China(Life Sciences)2016，59，3： | 3 |

| 10 | Design of biomimetic camouflage materials based on angiosperm leaf organs显示文摘The micro structures and reflectance spectra of angiosperm leaves were compared with those of angiosperm petals. The study indicated that angiosperm leaf organs had identical micro structures and reflectance characteristics in the wave band of near infrared. Micro structures and compositions of leaf organs were the crucial factors influencing their reflectance spectra. The model of biomimetic materials based on angiosperm leaf organs was introduced and verified. From 300 to 2600 nm, the similarity coefficients of reflectance spectra of the foam containing water and Platanus Orientalis Linn. leaves were all above 0.969. The biomimetic camou- flage material exhibited almost the same reflectance spectra with those of green leaves in ultraviolet, visible and near infrared wave bands. And its 'concolor and conspectrum' effect might take on reconnaissance of hyperspectral and ultra hy- perspectral imaging. | LIU ZhiMing WU WenJian HU BiRu | 2008 | Science China(Technological Sciences)2008，51，11： | 3 |

| 12 | Forest height mapping using inventory and multi-source satellite data over Hunan Province in southern China显示文摘Background:Accurate mapping of forest canopy heights at a fine spatial resolution over large geographical areas is challenging.It is essential for the estimation of forest aboveground biomass and the evaluation of forest ecosystems.Yet current regional to national scale forest height maps were mainly produced at coarse-scale.Such maps lack spatial details for decision-making at local scales.Recent advances in remote sensing provide great opportunities to fill this gap.Method:In this study,we evaluated the utility of multi-source satellite data for mapping forest heights over Hunan Province in China.A total of 523 plot data collected from 2017 to 2018 were utilized for calibration and validation of forest height models.Specifically,the relationships between three types of in-situ measured tree heights(maximum-,averaged-,and basal area-weighted-tree heights)and plot-level remote sensing metrics(multispectral,radar,and topo variables from Landsat,Sentinel-1/PALSAR-2,and SRTM)were analyzed.Three types of models(multilinear regression,random forest,and support vector regression)were evaluated.Feature variables were selected by two types of variable selection approaches(stepwise regression and random forest).Model parameters and model performances for different models were tuned and evaluated via a 10-fold cross-validation approach.Then,tuned models were applied to generate wall-to-wall forest height maps for Hunan Province.Results:The best estimation of plot-level tree heights(R2 ranged from 0.47 to 0.52,RMSE ranged from 3.8 to 5.3 m,and rRMSE ranged from 28%to 31%)was achieved using the random forest model.A comparison with existing forest height maps showed similar estimates of mean height,however,the ranges varied under different definitions of forest and types of tree height.Conclusions:Primary results indicate that there are small biases in estimated heights at the province scale.This study provides a framework toward establishing regional to national scale maps of vertical forest structure. | Wenli Huang Wankun Min Jiaqi Ding Yingchun Liu Yang Hu Wenjian Ni Huanfeng Shen | 2022 | Forest Ecosystems2022，9，1： | 2 |

| 15 | Theoretical study of the low-lying electronic excited states for molecular aggregates显示文摘We present here a brief summary of a National Natural Science Foundation Major Project entitled 'Theoretical study of the low-lying electronic excited state for molecular aggregates'. The project focuses on theoretical investigation of the electronic structures and dynamic processes upon photo-and electric-excitation for molecules and aggregates. We aim to develop reliable methodology to predict the optoelectronic properties of molecular materials related to the electronic excitations and to apply in the experiments. We identify two essential scientific challenges: (i) nature of intramolecular and intermolecular electronic excited states; (ii) theoretical description of the dynamic processes of the coupled motion of electronic excitations and nucleus. We propose the following four subjects of research: (i) linear scaling time-dependent density-functional theory and its application to open shell system; (ii) computational method development of electronic excited state for molecular aggregates; (iii) theoretical investigation of the time evolution of the excited state dynamics; (iv) methods to predict the optoelectronic properties starting from electronic excited state investigation for organic materials and experimental verifications. | SHUAI ZhiGang LIU WenJian LIANG WanZhen SHI Qiang CHEN Hui | 2013 | Science China Chemistry2013，56，9： | 2 |
| 16 | Theoretical study of low-lying excited states of molecular aggregates. I. Development of linear-scaling TD-DFT显示文摘The project aims to develop an integrated linear-scaling time-dependent density functional theory (TD-DFT) for studying low-lying excited states of luminescent molecular materials, especially those fluorescence and phosphorescence co-emitting systems. The central idea will be 'from fragments to molecule' (FF2M). That is, the fragmental information will be employed to synthesize the molecular wave function, such that the locality (transferability) of the fragments (functional groups) is directly built into the algorithms. Both relativistic and spin-adapted open-shell TD-DFT will be considered. Use of the renormalized exciton method will also be made to further enhance the efficiency and accuracy of TD-DFT. Solvent effects are to be targeted with the fragment-based solvent model. It is expected that the integrated TD-DFT and program will be of great value in rational design of luminescent molecular materials. | LIU WenJian MA Jing | 2013 | Science China Chemistry2013，56，9： | 2 |
