| 1 | The signal selection and processing method for polarization measurement radar显示文摘Based on the ambiguity function, a novel signal processing method for the polarization measurement radar is developed. One advantage of this method is that the two orthogonal polarized signals do not have to be perpendicular to each other, which is required by traditional methods. The error due to the correlation of the two transmitting signals in the traditional method, can be reduced by this new approach. A concept called ambiguity function matrix (AFM) is introduced based on this method. AFM is a promising tool for the signal selection and design in the polarization scattering matrix measurement. The waveforms of the polarimetric radar are categorized and analyzed based on AFM in this paper. The signal processing flow of this method is explained. And the polarization scattering matrix measurement performance is testified by simulation. Furthermore, this signal processing method can be used in the inter-pulse interval measurement technique as well as in the instantaneous measurement technique. | CHANG YuLiang WANG XueSong LI YongZhen XIAO ShunPing | 2009 | Science in China(Series F)2009,52,10: | 8 |
| 2 | Calibration method of phase distortions for cross polarization channel of instantaneous polarization radar system显示文摘A novel polarimetric calibration method for new target property measurement radar system is presented.Its application in the real radar system is also discussed.The analysis indicates that instantaneous polarization radar(IPR) has inherent cross-polarization measurement error.The proposed method can effectively eliminate this error,and thus enhance the polarization scattering matrix(PSM) measurement precision.The phase error caused by digital receiver's direct IF sampling and mixing of two orthogonal polarization channels can be removed.Consequently,the inherent error of target polarization scattering measurement of the instantaneous polarization radar system is well revised.It has good reference value for further ploarimetric calibration and high practical application prospect. | Huanyao Dai Yuliang Chang Dahai Dai Yongzhen Li XuesongWang | 2010 | Journal of Systems Engineering and Electronics2010,21,2: | 7 |
| 3 | Research on instantaneous polarization radar system and external experiment显示文摘Instantaneous polarization radar can obtain radar target polarization scattering matrix (PSM) by using single pulse echo.The system overcomes the defects of inter-pulse interval polarization measurement radar and accurately measures the PSM of the moving target.Thus the capabilities of detection,anti-jamming and target identification can be improved.The present paper reports the first international self-developed instantaneous polarization radar experimental system and,by using this system,the measurement experiments of target polarization characteristics are conducted.The results show that the performance of target instantaneous polarization measurement by different waveforms is good.The basic and common problems in polarization scattering feature extraction and recognition domain are solved. | WANG XueSong LI YongZhen DAI HuanYao CHANG YuLiang DAI DaHai MA Liang LIU Yong | 2010 | Chinese Science Bulletin2010,55,15: | 5 |
| 4 | In situ observation of C_(60)(C(COOH)_(2))_(2) interacting with living cells using fluorescence microscopy显示文摘The interactions between nanoparticles and living cells were investigated by an imaging technique of fluorescence microscopy. For this pur- pose, the C60 derivative C60(C(COOH)2)2, a thera- peutic agent for degeneration diseases of central nervous system, was synthesized, purified and characterized. Its interaction with the living cell and penetration of the cellular membrane were in situ studied using the real time imaging technique, and its potential cytotoxicity was also examined by flow cy- tometry. The results indicate that C60(C(COOH)2)2 can easily enter cells, and is mainly located in cytoplasm by fluorescein labeling. Furthermore, C60(C(COOH)2)2 can carry the molecule that cannot cross cellular membranes into cells, because fluo- rescein compound itself cannot enter the cell or ad- here to membrane. At concentrations ranging from 1×10?2 to 1×102 mg/L, C60(C(COOH)2)2 does not show any detectable cytotoxicity. | YE Chang CHEN Chunying CHEN Zhen MENG Huan XING Li JIANG Yaxin YUAN Hui XING Gengmei ZHAO Feng ZHAO Yuliang CHAI Zhifang FANG Xiaohong HAN Dong CHEN Long WANG Chen WEI Taotao | 2006 | Chinese Science Bulletin2006,51,9: | 4 |
| 5 | Anti-fatigue activity of Brassica rapa L.extract and correlation among biochemical changes in forced swimming mice显示文摘Brassica rapa L.is an edible and medical plant in China used for treating various diseases,especially in the Tibet region.In this study,the chemical constituents of Brassica rapa L.extract(BE)was clarified by UHPLC-MS and anti-fatigue ability of BE was assessed through the behavior test and weight-loaded forced swimming test in mice.Then we determined several biochemical parameters related to fatigue to explore possible reasons.Results indicate that BE could significantly enhance exercise performance in mice,and there was a significant improvement in both grip-strength and the time on rota-rods.Meanwhile,BE showed significant anti-fatigue effects by decreasing the blood lactic acid(BLA),blood urea nitrogen(BUN),and creatine kinase(CK)levels and increasing the lactate dehydrogenase(LDH)and malondialdehyde(MDA)levels.Increases in superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)were observed and reactive oxygen species(ROS)levels was regulated.Liver and muscle glycogen levels and adenosine triphosphate(ATP)levels were also significantly increased.Pearson correlation analysis indicates that fatigue-related indexes including metabolites and energy-related indexes were significantly correlated with antioxidant levels.In conclusion,BE possesses remarkable anti-fatigue activity,thereby shows great potential for improving exercise performance and alleviating physical fatigue and can be considered as a functional food supplement for further development. | Zilin Li Hongkang Zhu Hanyi Hua Chang Liu Yuliang Cheng Yahui Guo Peng Du He Qian | 2022 | Food Bioscience2022,47,3: | 2 |

| 7 | Development of a haploid inducer by editing HvMTL in barley显示文摘The doubled-haploid technique mediated by parthenogenesis and androgenesis in plants can directly generate homozygous diploid lines after chromosome doubling with colchicine in one or two generations,and this method undoubtedly shortens the breeding process and improves breeding efficiency in crops.Previously,haploid plants were mainly induced by anther culture or microspore culture via androgenesis(Ohnoutkova et al.,2019).In wheat(Triticum aestivum),haploids can also be induced by maize(Zea mays)pollen and chromosome elimination via parthenogenesis(Liu et al.,2020b).However,the aforementioned induction methods are genotype-dependent,require complex manipulations,and are both time-consuming and inefficient.Therefore,it is necessary to develop new techniques or germplasm for simple and efficient haploid induction. | Huali Tang Yuliang Qiu Wanxin Wang Mei Yu Yanan Chang Zhiyang Han Lipu Du Zhishan Lin Ke Wang Xingguo Ye | 2023 | Journal of Genetics and Genomics2023,50,5: | 1 |

| 11 | Novel polarimetric detector for target detection in heterogeneous clutter显示文摘A detection of static or slowly moving targets in the inhomogeneous clutter of polarimetric radar is researched and a new detector without exploiting the training set is developed, which has a good performance against the inhomogeneous clutter. The decision rule ensures the constant false alarm rate(CFAR) with respect to the disturbance covariance matrix. Numerical results show the robustness of the proposed method against the inhomogeneous clutter. | Xu Cheng Longfei Shi Yuliang Chang Yongzhen Li Xuesong Wang | 2016 | Journal of Systems Engineering and Electronics2016,27,6: | 0 |

| 13 | Romidepsin(FK228) improves the survival of allogeneic skin grafts through downregulating the production of donor-specific antibody via suppressing the IRE1α-XBP1 pathway显示文摘Antibody-mediated rejection(AMR)is one of the major causes of graft loss after transplantation.Recently,the regulation of B cell differentiation and the prevention of donor-specific antibody(DSA)production have gained increased attention in transplant research.Herein,we established a secondary allogeneic in vivo skin transplant model to study the effects of romidepsin(FK228)on DSA.The survival of grafted skins was monitored daily.The serum levels of DSA and the number of relevant immunocytes in the recipient spleens were evaluated by flow cytometry.Then,we isolated and purified B cells from B6mouse spleens in vitro by magnetic bead sorting.The B cells were cultured with interleukin-4(IL-4)and anti-clusters of differentiation 40(CD40)antibody with or without FK228 treatment.The immunoglobulin G1(IgG1)and IgM levels in the supernatant were evaluated by enzyme-linked immunosorbent assay(ELISA).Quantitative reverse transcription-polymerase chain reaction(RT-q PCR)and western blotting were conducted to determine the corresponding levels of messenger RNA(mRNA)and protein expression in cultured cells and the recipient spleens.The results showed that FK228 significantly improved the survival of allogeneic skin grafts.Moreover,FK228 inhibited DSA production in the serum along with the suppression of histone deacetylase 1(HADC1)and HDAC2 and the upregulation of the acetylation of histones H2A and H3.It also inhibited the differentiation of B cells to plasma cells,decreased the transcription of positive regulatory domain-containing 1(Prdm1)and X-box-binding protein 1(Xbp1),and decreased the expression of phosphorylated inositol-requiring enzyme 1α(p-IRE1α),XBP1,and B lymphocyte-induced maturation protein-1(Blimp-1).In conclusion,FK228 could decrease the production of antibodies by B cells via inhibition of the IRE1α-XBP1 signaling pathway.Thus,FK228 is considered as a promising therapeutic agent for the clinical treatment of AMR. | Yuliang GUO Siyu SONG Xiaoxiao DU Li TIAN Man ZHANG Hongmin ZHOU Zhonghua Klaus CHEN Sheng CHANG | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022,23,5: | 0 |
| 14 | A fast technique for visual screening of wheat haploids generated from TaMTL-edited mutants carrying anthocyanin markers显示文摘Dear Editor,Breeding a new wheat variety using traditional methods typically takes at least 8 to 10 years,and the breeding period can be dramatically shortened via a doubled haploid strategy,which can yield homozygotes within one or two generations.In the past several decades,wheat haploids have been widely induced through anther or microspore culture and chromosome elimination via interspecific hybridization between wheat and maize.The first technique exhibits strong genotype dependency and a severe albino phenomenon,whereas the latter shows low induction efficiency(Sangam et al.,2015).In addition,haploid induction procedures using the aforementioned methods are complicated to perform and require specialized equipment and environmentally controlled conditions.Thus,the application of these technologies in wheat breeding has been limited(Sangam et al.,2015). | Huali Tang Ke Wang Shuangxi Zhang Zhiyang Han Yanan Chang Yuliang Qiu Mei Yu Lipu Du Xingguo Ye | 2023 | Plant Communications2023,4,3: | 0 |
