| 1 | Far-field super-resolution imaging by nonlinearly excited evanescent waves显示文摘Abbe’s resolution limit,one of the best-known physical limitations,poses a great challenge for any wave system in imaging,wave transport,and dynamics.Originally formulated in linear optics,the Abbe limit can be broken using nonlinear optical interactions.We extend the Abbe theory into a nonlinear regime and experimentally demonstrate a far-field,label-free,and scan-free super-resolution imaging technique based on nonlinear four-wave mixing to retrieve near-field scattered evanescent waves,achieving a sub-wavelength resolution ofλ∕5.6.This method paves the way for numerous new applications in biomedical imaging,semiconductor metrology,and photolithography. | Zhihao Zhou Wei Liu Jiajing He Lei Chen Xin Luo Dongyi Shen Jianjun Cao Yaping Dan Xianfeng Chen Wenjie Wan | 2021 | Advanced Photonics2021，3，2： | 6 |
| 2 | Scale invariant features extraction for stereo vision显示文摘Stable local feature detection is a fundamental component of many stereo vision problems such as 3-D reconstruction, object localization, and object tracking. A robust method for extracting scale-invariant feature points is presented. First, the Harris corners in three-level pyramid are extracted. Then, the points detected at the highest level of the pyramid are correctly propagated to the lower level by pyramid based scale invariant (PBSI) method. The corners detected repeatedly in different levels are chosen as ffnal feature points. Finally, the characteristic scale is obtained based on maximum entropy method. The experimental results show that the algorithm has low computation cost, strong antinoise capability, and excellent performance in the presence of significant scale changes. | Liu Li Peng Fuyuan Tian Yani Wan Yaping | 2009 | Journal of Systems Engineering and Electronics2009，20，1： | 4 |

| 5 | Ribonuclease H-like gene SMALL GRAIN2 regulates grain size in rice through brassinosteroid signaling pathway显示文摘Grain size is a key agronomic trait that determines the yield in plants.Regulation of grain size by brassinosteroids(BRs)in rice has been widely reported.However,the relationship between the BR signaling pathway and grain size still requires further study.Here,we isolated a rice mutant,named small grain2(sg2),which displayed smaller grain and a semi-dwarf phenotype.The decreased grain size was caused by repressed cell expansion in spikelet hulls of the sg2 mutant.Using map-based cloning combined with a Mut Map approach,we cloned SG2,which encodes a plant-specific protein with a ribonuclease H-like domain.SG2 is a positive regulator downstream of GLYCOGEN SYNTHASE KINASE2(GSK2)in response to BR signaling,and its mutation causes insensitivity to exogenous BR treatment.Genetical and biochemical analysis showed that GSK2 interacts with and phosphorylates SG2.We further found that BRs enhance the accumulation of SG2 in the nucleus,and subcellular distribution of SG2 is regulated by GSK2 kinase activity.In addition,Oryza sativa OVATE family protein 19(OsOFP19),a negative regulator of grain shape,interacts with SG2 and plays an antagonistic role with SG2 in controlling gene expression and grain size.Our results indicated that SG2 is a new component of GSK2-related BR signaling response and regulates grain size by interacting with Os OFP19. | Yunshuai Huang Hui Dong Changling Mou Ping Wang Qixian Hao Min Zhang Hongmin Wu Fulin Zhang Tengfei Ma Rong Miao Kai Fu Yaping Chen Ziyan Zhu Cheng Chen Qikai Tong Zhuoran Wang Shirong Zhou Xi Liu Shijia Liu Yunlu Tian Ling Jiang Jianmin Wan | 2022 | Journal of Integrative Plant Biology2022，64，10： | 1 |
| 6 | Using Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry to analyze differentially expressed brain polypeptides in scrapie strain 22L-infected BALB/c mice显示文摘Differentially expressed polypeptides in the brain of a BALB/c mouse model infected with scrapie strain 22L were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.The results showed that 21 peptides were down-regulated,with peptides of mass-to-charge ratio 758.772 5 and mass-to-charge ratio 5 432.206 9,demonstrating the most significant decreases.These finding suggest that these peptides are candidate biomarkers and may play an important role in the pathogenesis of prion disease. | Xiangyu Liao Jiayu Wan Wensen Liu Xin Tang Wufei Zhu Na XU Jing Xu Nan Li Yaping Chang Chuanjing Ju | 2011 | Neural Regeneration Research2011，6，23： | 1 |
| 7 | Secure Underwater Distributed Antenna Systems: A Multi-Agent Reinforcement Learning Approach显示文摘Dear Editor,Underwater distributed antenna systems(DAS) are stationary infrastructures consisting of multiple geographically distributed antenna elements(DAEs) which are interconnected through high-rate backbone networks [1]. Compared to centralized systems, the DAS could provide a larger coverage area and higher throughput for underwater acoustic(UWA) transmissions. In this work, exploiting the low sound speed in water, a multi-agent reinforcement learning(MARL)-based approach is proposed to secure underwater DAS against eavesdropping at the physical layer. | Chaofeng Wang Zhicheng Bi Yaping Wan | 2023 | IEEE/CAA Journal of Automatica Sinica2023，10，7： | 0 |
| 8 | A bifunctional vinyl-sulfonium tethered peptide induced by thio-Michael-type addition reaction显示文摘The modification and functionalization of peptides is of great significance in modern biotechnology and drug development. Here we report a highly reactive Michael-type warhead for the covalently modification of cysteine on peptide and protein. By installing a vinyl group onto a methionine residue of peptide,the produced vinyl sulfonium can be efficiently nucleophilic added by appropriate cysteine residue of this peptide, and thus yield a cyclized peptide. This peptide cyclization strategy was proven to exhibit improved cell penetration and good stability. Moreover, a peptide ligand bearing vinyl sulfonium could covalently bind to the cysteine in the target protein, indicating the potential of vinyl sulfonium as a novel warhead for developing covalent peptide inhibitor. | Hongkun Xu Xuan Qin Yaping Zhang Chuan Wan Rui Wang Zhanfeng Hou Xiaofeng Ding Hailing Chen Ziyuan Zhou Yang Li Chenshan Lian Feng Yin Zigang Li | 2022 | Chinese Chemical Letters2022，33，4： | 0 |
| 9 | Young Leaf White Stripe encodes a P-type PPR protein required for chloroplast development显示文摘Pentatricopeptide repeat(PPR) proteins function in post-transcriptional regulation of organellar gene expression. Although several PPR proteins are known to function in chloroplast development in rice(Oryza sativa), the detailed molecular functions of many PPR proteins remain unclear.Here, we characterized a rice young leaf white stripe(ylws) mutant, which has defective chloroplast development during early seedling growth.Map-based cloning revealed that YLWS encodes a novel P-type chloroplast-targeted PPR protein with 11 PPR motifs. Further expression analyses showed that many nuclear-and plastid-encoded genes in the ylws mutant were significantly changed at the RNA and protein levels. The ylws mutant was impaired in chloroplast ribosome biogenesis and chloroplast development under low-temperature conditions. The ylws mutation causes defects in the splicing of atpF, ndhA, rpl2,and rps12, and editing of ndhA, ndhB, and rps14transcripts. YLWS directly binds to specific sites in the atpF, ndhA, and rpl2 pre-mRNAs. Our results suggest that YLWS participates in chloroplast RNA group II intron splicing and plays an important role in chloroplast development during early leaf development. | Jie Lan Qibing Lin Chunlei Zhou Xi Liu Rong Miao Tengfei Ma Yaping Chen Changling Mou Ruonan Jing Miao Feng Thanhliem Nguyen Yulong Ren Zhijun Cheng Xin Zhang Shijia Liu Ling Jiang Jianmin Wan | 2023 | Journal of Integrative Plant Biology2023，65，7： | 0 |
