| 1 | Ce and W co-doped CaBi_(2)Nb_(2)O_(9) with enhanced piezoelectric constant and electrical resistivity at high temperature显示文摘Ce and W co-doped CaBi_(2)Nb_(2)O_(9) ceramics with chemical formula Ca_(0.96)Ce_(0.04)Bi_(2)Nb_(2-x)W_(x)O_(9)(CCBNW100x,x=0-0.07)are fabricated via conventional solid state sintering method,to investigate the effect of W addition on the structure,electrical resistivity,dielectric and piezoelectric properties.A piezoelectric constant d33 of 13.4 pC/N is obtained in CCBN-W2 ceramics,>100% higher than that of pure CaBi_(2)Nb_(2)O_(9)(d_(33)=5.8e6.4 pC/N).Of particular significance is that the electrical resistivity of CCBN-W2 ceramics(r=3.7×109 U cm at 500℃)is three orders of magnitude higher than pure CaBi_(2)Nb_(2)O_(9)(r=2.9×10^(6) U cm at same temperature).All these properties,together with its low dielectric loss(tandδ0.13%)and excellent d33 thermal stability up to 800℃,merit the CCBN-W2 ceramics for high temperature piezoelectric sensing applications. | Zong-Yang Shen Chen Qin Wen-Qin Luo Fusheng Song Zhumei Wang Yueming Li Shujun Zhang | 2020 | Journal of Materiomics2020，6，3： | 7 |
| 2 | Robust key point descriptor for multi-spectral image matching显示文摘Histogram of collinear gradient-enhanced coding(HCGEC), a robust key point descriptor for multi-spectral image matching, is proposed. The HCGEC mainly encodes rough structures within an image and suppresses detailed textural information,which is desirable in multi-spectral image matching. Experiments on two multi-spectral data sets demonstrate that the proposed descriptor can yield significantly better results than some state-ofthe-art descriptors. | Yueming Qin Zhiguo Cao Wen Zhuo Zhenghong Yu | 2014 | Journal of Systems Engineering and Electronics2014，25，4： | 3 |
| 3 | Shikonin alleviates collagen-induced arthritis mice by inhibiting M1 macrophage polarization显示文摘OBJECTIVE: To investigate the effects of shikonin(SKN) on M1 and M2 polarization of macrophages both in vitro and in vivo. METHODS: Collagen-induced arthritis(CIA) in male DBA/1 mice were treated with a dose of 4 mg/kg/day of SKN for 23 d(n = 6/group). The histopathology of inflamed joints in CIA mice was evaluated to test the antiarthritic effect of SKN. M1/M2 polarization of macrophages induced by lipopolysaccharide(LPS) and interferon(IFN)-γ or interleukin(IL)-4 and IL-13, were used to assess the effect of SKN(0.05, 0.1, and 0.2 μM). The effect of SKN on the protein expression of nitric oxide synthase, arginase, CD68, and CD206 was evaluated using western blot analysis. RESULTS: The results of this study revealed that SKN delayed the arthritis feet symptom score, reduced the incidence rate of arthritis, and relieved the inflammation of joints in CIA mice. SKN inhibited M1 macrophage polarization but did not affect M2 macrophage polarization in the joints of CIA mice. Moreover, SKN inhibited M1 polarization induced by LPS and IFN-γ, but did not affect M2 polarization induced by IL-4 and IL-13. CONCLUSION: These findings suggest that SKN alleviated CIA through inhibiting M1 macrophage polarization and has great potential as a new drug for RA treatment. | HE Lianhua LUAN Huijie QIN Qingxia HE Juan CHEN Jian HU Yiping CAI Yueming SUN Desheng SHI Yu WANG Qingwen | 2022 | Journal of Traditional Chinese Medicine2022，42，6： | 2 |

| 5 | Experience and inspirations of the Mass Drug Administration Programme with artemisinin-piperaquine in Moheli Island of the Comoros assisted by China显示文摘Malaria is one of the major diseases threatening the lives of people in Africa.Over the past decade,China has provided anti-malaria assistance to Africa.In November 2007,fast control malaria team of Guangzhou University of Chinese Medicine cooperated with the Comoros health authority.In Moheli Island of the Comoros,the anti-malaria team adopted a new strategy of Mass Drug Administration(MDA)and active intervention.They established an e ective anti-malaria system and reporting system,as well as a local anti-malaria team.Furthermore,they treated patients with malaria in Moheli Island and implemended health education in local people.In a very short time,they have achieved remarkable results.This paper summarized the experiences of the project in order to provide useful reference for China to better carry out anti-malaria action in Africa and expand foreign health assistance. | Qi Wang Yueming Yun Hongying Zhang Jiawen Guo Wanting Wu Changsheng Deng Bo Huang Zhiyong Xu Qin Xu Jianping Song | 2018 | Global Health Journal2018，2，3： | 1 |
| 6 | Extracting the phase distribution of the electron wave packet ionized by an elliptically polarized laser pulse显示文摘We use an interferometic scheme to extract the phase distribution of the electron wave packet from above-threshold ionization in elliptically polarized laser fields.In this scheme,an electron wave packet released from a circularly polarized laser pulse acts as a reference wave and interferes with the electron wave packet ionized by a time-delayed counter-rotating elliptically polarized laser field.The generated vortex-shaped interference pattern in the photoelectron momentum distribution enables us to extract the phase distribution of the electron wave packet in the elliptically polarized laser pulse with high precision.By artificially screening the ionic potential at different ranges when solving the time-dependent Schördinger equation,we find that the angle-dependent phase distribution of the electron wave packet in the elliptically polarized laser field shows an obvious angular shift as compared to the strong-field approximation,whose value is the same as the attoclock shift.We also show that the amplitude of the angle-dependent phase distribution is sensitive to the ellipticity of the laser pulse,providing an alternative way to precisely calibrate the laser ellipticity in the attoclock measurement. | Ya-Nan Qin Min Li Yudi Feng Siqiang Luo Yueming Zhou Peixiang Lu | 2021 | Frontiers of physics2021，16，3： | 0 |
