1Physical modeling and spectrum spread analysis of surface clutter in forward scattering radar显示文摘In this paper, based on the processing results of measured clutter data in forward scattering radar, a special phenomenon that the clutter spectrum spread is insensitive to the wind speed and carrier frequency is observed. The pendulum model is first time introduced into the physical modeling and formation mechanism analysis of surface clutter, and the quantitative expression of clutter spectrum spread is analytically obtained. Under the assumption of pendulum model, the processing results of measured clutter data agree well with the results of theoretical analysis, which fully verifies the correctness of pendulum model and reveals the formation mechanism of surface clutter spectrum in forward scattering radar. Furthermore, according to the stability of clutter spectrum spread with respect to carrier frequencies and wind speed, the optimal cutofrequencies of clutter filter can be obtained, which establishes the basis for moving target detection and accurate parameters estimation.LONG Teng, HU Cheng, ZENG Tao & LI XiaoLiang Radar Research Laboratory, Department of Electronic Engineering, Beijing Institute of Technology, Beijing 100081, China 2010Science China(Information Sciences)2010,53,11:11

3Controlled fabrication of nanoscale wrinkle structure by fluorocarbon plasma for highly transparent triboelectric nanogenerator显示文摘In this paper,we report a novel nanoscale wrinkle-structure fabrication process using fluorocarbon plasma on poly(dimethylsiloxane)(PDMS)and Solaris membranes.Wrinkles with wavelengths of hundreds of nanometers were obtained on these two materials,showing that the fabrication process was universally applicable.By varying the plasma-treating time,the wavelength of the wrinkle structure could be controlled.Highly transparent membranes with wrinkle patterns were obtained when the plasmatreating time was o125 s.The transmittances of these membranes were 490%in the visible region,making it difficult to distinguish them from a flat membrane.The deposited fluorocarbon polymer also dramatically reduced the surface energy,which allowed us to replicate the wrinkle pattern with high precision onto other membranes without any surfactant coating.The combined advantages of high electron affinity and high transparency enabled the fabricated membrane to improve the performance of a triboelectric nanogenerator.This nanoscale,single-step,and universal wrinkle-pattern fabrication process,with the functionality of high transparency and ultra-low surface energy,shows an attractive potential for future applications in microand nanodevices,especially in transparent energy harvesters.Xiaoliang Cheng Liming Miao Zongming Su Haotian Chen Yu Song Xuexian Chen Haixia Zhang 2017Microsystems & Nanoengineering2017,3,1:3
4An accurate SISAR imaging method of ground moving target in forward scatter radar显示文摘In order to accurately extract the profile image of the ground moving targets(GMT) in the forward scatter radar(FSR),a forward scatter signal model of GMT is built based on the Fresnel-Kirchhoff diffraction formula,the multipath propagation model and the high order phase approximation method.The classical shadow inverse synthetic aperture radar(SISAR) imaging algorithm is modified using the proposed signal model.In the modified imaging algorithm,the impacts of ground reflection,non-linear variation of target Doppler frequency and the target motion direction on imaging accuracy are discussed.Meanwhile,non-linear and time-dependent parameters are used to compensate for the motion phase of the GMT forward scatter signal,and a novel estimation method of the height difference and median line height of the target profile is put forward under the multipath interference.Finally,both the accuracy of the proposed signal model and the effectiveness of the modified imaging algorithm are validated by the simulation results.HU Cheng LI XiaoLiang LONG Teng ZHOU Chao 2012Science China(Information Sciences)2012,55,10:3

6The advanced development of molecular targeted therapy for hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC),one of the most common malignant tumors in China,severely threatens the life and health of patients.In recent years,precision medicine,clinical diagnoses,treatments,and innovative research have led to important breakthroughs in HCC care.The discovery of new biomarkers and the promotion of liquid biopsy technologies have greatly facilitated the early diagnosis and treatment of HCC.Progress in targeted therapy and immunotherapy has provided more choices for precise HCC treatment.Multiomics technologies,such as genomics,transcriptomics,and metabolomics,have enabled deeper understanding of the occurrence and development mechanisms,heterogeneity,and genetic mutation characteristics of HCC.The continued promotion and accurate typing of HCC,accurate guidance of treatment,and accurate prognostication have provided more treatment opportunities and prolonged survival timelines for patients with HCC.Innovative HCC research providing an in-depth understanding of the biological characteristics of HCC will be translated into accurate clinical practices for the diagnosis and treatment of HCC.Tao Yan Lingxiang Yu Ning Zhang Caiyun Peng Guodong Su Yi Jing Linzhi Zhang Tong Wu Jiamin Cheng Qian Guo Xiaoliang Shi Yinying Lu 2022Cancer Biology & Medicine2022,19,6:2
7Lipidomic and transcriptomic analysis reveals reallocation of carbon flux from cuticular wax into plastid membrane lipids in a glossy“Newhall”navel orange mutant显示文摘Both cuticle and membrane lipids play essential roles in quality maintenance and disease resistance in fresh fruits.Many reports have indicated the modification of alternative branch pathways in epicuticular wax mutants;however,the specific alterations concerning lipids have not been clarified thus far.Here,we conducted a comprehensive,timeresolved lipidomic,and transcriptomic analysis on the“Newhall”navel orange(WT)and its glossy mutant(MT)“Gannan No.1”.The results revealed severely suppressed wax formation accompanied by significantly elevated production of 36-carbon plastid lipids with increasing fruit maturation in MT.Transcriptomics analysis further identified a series of key functional enzymes and transcription factors putatively involved in the biosynthesis pathways of wax and membrane lipids.Moreover,the high accumulation of jasmonic acid(JA)in MT was possibly due to the need to maintain plastid lipid homeostasis,as the expression levels of two significantly upregulated lipases(CsDAD1 and CsDALL2)were positively correlated with plastid lipids and characterized to hydrolyze plastid lipids to increase the JA content.Our results will provide new insights into the molecular mechanisms underlying the natural variation of plant lipids to lay a foundation for the quality improvement of citrus fruit.Haoliang Wan Hongbo Liu Jingyu Zhang Yi Lyu Zhuoran Li Yizhong He Xiaoliang Zhang Xiuxin Deng Yariv Brotman Alisdair RFernie Yunjiang Cheng Weiwei Wen 2020Horticulture Research2020,7,1:2
8A cubic triboelectric generator as a self-powered orientation sensor显示文摘Recently, triboelectric generator(TEG) has attracted a lot of attention due to its high output voltage and low-cost fabrication process. Here, a novel cubic TEG box is designed, which has separated electrodes on different surfaces. Thanks to the specially designed structure, it can scavenge vibration energy from all directions. Firstly the device is investigated through finite element method(FEM) simulation. Then the device is evaluated by experiments. The measuremental results show that this device can generate an amount of 25 n C charge during once shake by charging a 10 n F capacitor. Besides, an output voltage about 100 V is obtained, which is able to directly light up several light-emitting diodes(LEDs) simultaneously. At last, the device is utilized as a self-powered orientation sensor, which shows explicit directivity. This work extends the applications of TEG for ambient vibration energy harvesting techniques and the self-powered orientation sensor.QIU GuoLin LIU Wen HAN MengDi CHENG XiaoLiang MENG Bo SMITHA Ankanahalli Shankaregowda ZHAO JiangMing ZHANG HaiXia 2015Science China(Technological Sciences)2015,58,5:2
9A simulator with an elastic guidewire and vascular system for minimally invasive vascular surgery显示文摘Simulators play an important role in minimally invasive vascular surgery training. A challenging task for the simulator is to model an elastic guidewire and an elastic vascular system, both of which are important aspects for vascular surgery.However, many simulators treat the virtual vascular system as a rigid object, which reduces the immersion of operators. In this study, a virtual guidewire is first modeled based on CosseratXiaoran CHENG Xiaoliang XIE Guibin BIAN Zengguang HOU Shiqi LIU Zhanjie GAO 2018Science China(Information Sciences)2018,61,10:2
10Integrated multi-omics analysis of developing‘Newhall’orange and its glossy mutant provide insights into citrus fragrance formation显示文摘Sesquiterpene valencene is dominant in flavedo tissues of sweet oranges and imparts a unique woody aroma.However,the interaction between the biosynthetic pathways of valencene and other nutritional compounds is less studied.Sesquiterpenoids were significantly accumulated in a previously reported glossy mutant of orange(MT)than the wild type(WT),especially valencene and caryophyllene.In addition,we identified several other pathways with variations at both the transcriptional and metabolic levels in MT.It’s interesting to found those upregulated metabolites in MT,such as eukaryotic lipids,kaempferol and proline also showed strong positive correlation with valencene along with fruit maturation while those down-regulated metabolites,such as phenylpropanoid coumarins and most of the modified flavonoids exhibited negative correlation.We then categorized these shifted pathways into the‘sesquitepenoid-identical shunt’and the sesquitepenoid-opposite shunt’and confirmed the classification result at transcriptional level.Our results provide important insights into the connections between various fruit quality-related properties.Haoliang Wan Xiaoliang Zhang Ping Wang Haiji Qiu Yafei Guo Yunjiang Cheng Weiwei Wen 2022Horticultural Plant Journal2022,8,4:2
11A Variational Binary Level Set Method for Structural Topology Optimization显示文摘This paper proposes a variational binary level set method for shape and topology optimization of structural.First,a topology optimization problem is presented based on the level set method and an algorithm based on binary level set method is proposed to solve such problem.Considering the difficulties of coordination between the various parameters and efficient implementation of the proposed method,we present a fast algorithm by reducing several parameters to only one parameter,which would substantially reduce the complexity of computation and make it easily and quickly to get the optimal solution.The algorithm we constructed does not need to re-initialize and can produce many new holes automatically.Furthermore,the fast algorithm allows us to avoid the update of Lagrange multiplier and easily deal with constraints,such as piecewise constant,volume and length of the interfaces.Finally,we show several optimum design examples to confirm the validity and efficiency of our method.Xiaoxia Dai Peipei Tang Xiaoliang Cheng Minghui Wu 2013Communications in Computational Physics2013,13,5:1
