| 1 | Nuclear Aurora kinase A switches m^(6)A reader YTHDC1 to enhance an oncogenic RNA splicing of tumor suppressor RBM4显示文摘Aberrant RNA splicing produces alternative isoforms of genes to facilitate tumor progression,yet how this process is regulated by oncogenic signal remains largely unknown.Here,we unveil that non-canonical activation of nuclear AURKA promotes an oncogenic RNA splicing of tumor suppressor RBM4 directed by m^(6)A reader YTHDC1 in lung cancer.Nuclear translocation of AURKA is a prerequisite for RNA aberrant splicing,specifically triggering RBM4 splicing from the full isoform(RBM4-FL)to the short isoform(RBM4-S)in a kinase-independent manner. | SiSi Li YangFan Qi JiaChuan Yu YuChao Hao Bin He MengJuan Zhang ZhenWei Dai TongHui Jiang SuYi Li Fang Huang Ning Chen Jing Wang MengYing Yang DaPeng Liang Fan An JinYao Zhao WenJun Fan YuJia Pan ZiQian Deng YuanYuan Luo Tao Guo Fei Peng ZhiJie Hou ChunLi Wang FeiMeng Zheng LingZhi Xu Jie Xu QingPing Wen BiLian Jin Yang Wang Quentin Liu | 2022 | Signal Transduction and Targeted Therapy2022，7，5： | 4 |
| 2 | NON-LOCAL MODELING ON MACROSCOPIC DOMAIN PATTERNS IN PHASE TRANSFORMATION OF NiTi TUBES显示文摘Recent experiments[ 1]revealed many new phenomena of the macroscopic domain patterns in the stress-induced phase transformation of a superelastic polycrystalline NiTi tube during tensile loading.The new phenomena include deformation instability with the formation of a helical domain,domain topology transition from helix to cylinder,domain-front branching and loading-path dependence of domain patterns.In this paper,we model the polycrystal as an elastic continuum with nonconvex strain energy[ 2]and adopt the non-local strain gradient energy to account for the energy of the diffiusive domain front.We simulate the equilibrium domain patterns and their evolution in the tubes under tensile loading by a non-local Finite Element Method (FEM).It is revealed that the observed loading-path dependence and topology transition of domain patterns are due to the thermodynamic metastability of the tube system.The computation also shows that the tube-wall thickness has a significant effect on the domain patterns:with fixed material properties and interfacial energy density,a large tube-wall thickness leads to a long and slim helical domain and a severe branching of the cylindrical-domain front. | Yongjun He Qingping Sun | 2009 | Acta Mechanica Solida Sinica2009，22，5： | 3 |

| 6 | Enrichment characteristics and sources of the critical metal yttrium in Zhijin rare earth-containing phosphorites, Guizhou Province, China显示文摘Yttrium(Y)is a critical metallic element that is used widely in modern scientific,technological,and industrial applications.Phosphorites in the Zhijin area of Guizhou Province,China,are famous for Y enrichment,but the enrichment characteristics and sources remain unclear.Previous studies suggested that the sources of rare earth elements(REEs,La-Lu)and Y(REYs,La-Lu+Y)were related to hydrothermal deposition.However,this study presents evidence refuting that hypothesis,with major and trace elemental data collected with quadrupoleinductively coupled plasma-mass spectrometry(Q-ICPMS)analysis.These data show that Y in Zhijin REYscontaining phosphorites has a normal distribution and is particularly enriched relative to other REYs.The Y enrichment degree is different at different∑REY intervals.Specifically,the Y enrichment degree is higher at lower∑REY values and lower at higher∑REY values.The REYs-containing phosphorites show features of primary phosphorites.Both REEs and Y have good correlations with P2 O5 in the phosphorites with low REYs contents(total REYs<535 ppm),whereas at high REYs contents(total REYs>535 ppm),REEs have a good correlation with P2 O5 but Y does not.Inconsistent enrichment processes of REYs are suggestive of complex sources of Y.Thus,seafloor hydrothermal fluids were not the direct source of Y.Normal seawater mixed with terrestrial sources might have contributed to the origin of Y here.This study could lead to improvements in Y mineral resource explorations and the situation involving the global REYs supply crisis. | Xingxiang Gong Shengwei Wu Yong Xia Zhengwei Zhang Shan He Zhuojun Xie Jiafei Xiao Haiying Yang Qingping Tan Yi Huang Yuhong Yang | 2021 | Acta Geochimica2021，40，3： | 1 |

| 10 | Photo-induced fusion of monodisperse polymer microspheres:A novel strategy for constructing topological microsphere clusters with improved stability显示文摘The preparation of monodisperse azobenzene(Azo)polymer microspheres by dispersion polymerization was reported.The photo-induced fusion of Azo polymer microspheres was successfully achieved during the process of reversible trans-cistrans photoisomerization of Azo units,and induced various unique“microsphere molecular”clusters or“microsphere polymers”.Encouraged by this interesting phenomenon,microsphere clusters of different topological structures were stabilized by the in situ acetal cross-linking chemistry.The photo-induced fusion polymerization of monodisperse polymer microspheres provides a new strategy for designing photo-responsive clusters and allows for control over the mechanical properties of microspheres with high spatiotemporal resolution. | Zixiang He Su Shen Gong Zhang Tengfei Miao Xiaoxiao Cheng Zhao Wang Qingping Song Wei Zhang | 2023 | Aggregate2023，4，5： | 0 |
| 11 | Experimental study on sand particles accumulation,migration and separation efficiency in slug catcher显示文摘Sand production often leads to the failure of production equipment on offshore platform.Therefore,a new idea has been put forward,which is installing cyclone or baffle in the internal of the slug catcher for better sand control.In this paper,an experimental study is presented,which mainly includes sand particles accumulation shape,migration law and separation performance.The results suggest that the accumulation area is mainly divided into two zones:the crowded settlement zone and the free settlement zone.The crowded settlement zone has a special shape,which can be characterized by two parameters:accumulation length and accumulation angle.Axial sampling analysis shows obvious particle classification.Median particle size decreases with the increase of the axial distance,and the range of particle size distribution narrows gradually.The separation experiment shows that the gas velocity has the greatest influence on the separation efficiency.When the gas velocity is 14 m·s^ 1,the separation efficiency drops sharply,which can be abated by installing cyclone separator.In addition,the separation efficiency tends to be a constant under different gas velocities by installing baffle with appropriate height.Then the effectiveness and rationality of installing internal components can be strongly proved.All these provide important guidance for maximizing the sand control function of the slug catcher. | Xianchao Liang Limin He Xiaoming Luo Qingping Li Yuanpeng You Yiqiu Xu | 2021 | Chinese Journal of Chemical Engineering2021，34，4： | 0 |

| 13 | Pulse Signal Recovery Method Based on Sparse Representation显示文摘Pulse signal recovery is to extract useful amplitude and time information from the pulse signal contaminated by noise. It is a great challenge to precisely recover the pulse signal in loud background noise. The conventional approaches,which are mostly based on the distribution of the pulse energy spectrum,do not well determine the locations and shapes of the pulses. In this paper,we propose a time domain method to reconstruct pulse signals. In the proposed approach,a sparse representation model is established to deal with the issue of the pulse signal recovery under noise conditions. The corresponding problem based on the sparse optimization model is solved by a matching pursuit algorithm. Simulations and experiments validate the effectiveness of the proposed approach on pulse signal recovery. | Jiangmei Zhang Haibo Ji Qingping Zhu Hongsen He Kunpeng Wang | 2018 | Journal of Beijing Institute of Technology2018，27，2： | 0 |
| 14 | Simulation of bacterial flagellar phase transition by non-convex and non-local continuum modeling显示文摘Bacterial flagellar filament can undergo a stress-induced polymorphic phase transition in both vitro and vivo environments.The filament has 12 different helical forms(phases) characterized by different pitch lengths and helix radii.When subjected to the frictional force of flowing fluid,the filament changes between a left-handed normal phase and a right-handed semi-coiled phase via phase nucleation and growth.This paper develops non-local finite element method(FEM) to simulate the phase transition under a displacement-controlled loading condition(controlled helix-twist).The FEM formulation is based on the Ginzburg-Landau theory using a one-dimensional non-convex and non-local continuum model.To describe the processes of the phase nucleation and growth,viscosity-type kinetics is also used.The non-local FEM simulation captures the main features of the phase transition:two-phase coexistence with an interface of finite thickness,phase nucleation and phase growth with interface propagation.The non-local FEM model provides a tool to study the effects of the interfacial energy/thickness and loading conditions on the phase transition. | Xiaoling Wang,1,a) Yongjun He,2,b) and Qingping Sun 3,c) 1) School of Mechanical Engineering,University of Science and Technology Beijing,Beijing 100083,China 2) UME-MS,ENSTA-ParisTech,Chemin de la Huni`ere,91761 Palaiseau Cedex,France 3) Department of Mechanical Engineering,The Hong Kong University of Science and Technology,Clear Water Bay,Kowloon,Hong Kong,China | 2011 | Theoretical & Applied Mechanics Letters2011，1，4： | 0 |
| 15 | Fiber-dominated Soft Actuators Inspired by Plant Cell Walls and Skeletal Muscles显示文摘Morphing botanical tissues and animal muscles are all fiber-mediated composites, in which fibers play a passive and active role, respectively. Herein, inspired by the mechanism of fibers functioning in morphing botanical tissues and animal muscles, we propose two sorts of fiber-dominated composite actuators. First, inspired by the deformation of awned seeds in response to humidity change, we fabricate passive fiber-dominated actuators using non-active aligned carbon fibers via 4D printing method. The effects of process parameters, structural parameters, and fiber angles on the deformation of the printed actuators are examined. The experimental results show that the orientation degree is enhanced, resulting in a better swelling effect as the printing speed increases. Then, motivated by the actuation mechanism of skeletal muscle, we prepare active fiber-dominated actuators using active polyurethane fibers via 4D printing and pre-stretching method. The effect of fiber angle and loading on the actuation mode is experimentally analyzed. The experimental results show that the rotation angle of the actuator gradually decreases with the angle from 45° to 60°. When the fiber angle is 0° and 90°, the driver basically stops rotating while shrinking along the loading direction. Based on the above actuation mechanisms, identical contraction behaviors are realized both in passive and active fiber-dominated soft actuators. This work provides a validation method for biologically actuation mechanisms via 4D printing technique and smart materials and adds further insights to the design of bioinspired soft actuators. | Luquan Ren Qian Wu Qingping Liu Lei Ren Kunyang Wang Xueli Zhou Zhenguo Wang Yulin He Che Zhao Bingqian Li | 2023 | Journal of Bionic Engineering2023，20，3： | 0 |
