1Modeling and simulation of non-linear dynamic process of the induction motor system with fluctuating potential loads显示文摘The induction motor system with fluctuating potential loads is a non-linear complex electro-mechanical system.With beam pumping motors as an example,this paper proposes a multiple factor non-linear mathematical model to study the operating performance of the induction motor system.This model consists of non-linear time varying electromagnetic field equations,mechanical wave equations of sucker rods and non-linear coupling equation of reducer and four-bar linkage.The equations are numerically solved by combining time-step finite element method(TS-FEM),finite difference method(FDM),a linear dimension reduction method and the Newton-Raphson method.Simulation results,which are validated by experiments,reveal the influence of the fluctuating potential load on magnetic field distributions,stator and rotor currents,the input power and the power factor.The model and simulation results provide theoretical and technical supports for subsequent researches on model simplification and energy saving technologies.LUO Wei WANG Bo ZHAO HaiSen LUO YingLi 2014Science China(Technological Sciences)2014,57,9:13
2Using borehole core analysis to reveal Late Quaternary paleoearthquakes along the Nankou-Sunhe Fault,Beijing显示文摘The Nankou-Sunhe Fault is a buried active normal fault that traverses the urban area of Beijing.Its seismic risks have caused considerable concerns.This paper studies paleoearthquakes along this fault by analyzing and correlating bore-hole cores obtained from triple-tube coring,incorporating experience acquired from trenching.As a result,a model for identifying earthquake-derived colluvium by sediment-core analysis is proposed.Triple-tube coring technique is useful to collect continuous undis-turbed soil core near the Nankou-Sunhe Fault.By identifying fault-scarp colluviums,determining cumulative displacement,and analysing stratum thickening on the hanging wall,we are able to establish a preliminary paleoearthquake sequence consisting of 13 surface-rupturing events since 60 ka.The seismic history can be divided into three periods based on different recurrence intervals.Between 60 and 40 ka,three earthquakes occurred with recurrence interval of ~10 ka.From 40 to 25 ka,there were six earthquakes with the recurrence interval of about 2.5 ka.In the last 25 ka,four earthquakes have taken place with the recurrence interval varying considerably.The recurrence interval between the last three events is ~5 ka.Smaller recurrence intervals correspond to stages of faster fault slip.The coseismic displacement of a single event is 0.8 to 2.2 m,average 1.4 m,largely equivalent to moment magnitudes 6.7-7.1.This study demonstrates the feasibility of bore-hole drilling in investigating paleoearthquakes along normal faults.It also suggests that closely spaced boreholes with continuous undisturbed cores are essential for reconstructing the complete paleoearthquake sequence.ZHANG ShiMin WANG DanDan LIU XuDong ZHANG GuoHong ZHAO JunXiang LUO MingHui REN JunJie WANG Rui ZHANG YingLi 2008Science China Earth Sciences2008,51,8:11
3Crosstalk-free achromatic full Stokes imaging polarimetry metasurface enabled by polarization-dependent phase optimization显示文摘Imaging polarimetry is one of the most widely used analytical technologies for object detection and analysis.To date,most metasurface-based polarimetry techniques are severely limited by narrow operating bandwidths and inevitable crosstalk,leading to detrimental effects on imaging quality and measurement accuracy.Here,we propose a crosstalkfree broadband achromatic full Stokes imaging polarimeter consisting of polarization-sensitive dielectric metalenses,implemented by the principle of polarization-dependent phase optimization.Compared with the single-polarization optimization method,the average crosstalk has been reduced over three times under incident light with arbitrary polarization ranging from 9μm to 12μm,which guarantees the measurement of the polarization state more precisely.The experimental results indicate that the designed polarization-sensitive metalenses can effectively eliminate the chromatic aberration with polarization selectivity and negligible crosstalk.The measured average relative errors are 7.08%,8.62%,7.15%,and 7.59%at 9.3,9.6,10.3,and 10.6μm,respectively.Simultaneously,the broadband full polarization imaging capability of the device is also verified.This work is expected to have potential applications in wavefront detection,remote sensing,light-field imaging,and so forth.Yaxin Zhang Mingbo Pu Jinjin Jin Xinjian Lu Yinghui Guo Jixiang Cai Fei Zhang Yingli Ha Qiong He Mingfeng Xu Xiong Li Xiaoliang Ma Xiangang Luo 2022Opto-Electronic Advances2022,5,11:6
4Time-stepping finite element analysis on the influence of skewed rotors and different skew angles on the losses of squirrel cage asynchronous motors显示文摘To study the influence of skewed rotors and different skew angles on the losses of squirrel cage asynchronous motors,a 5.5-kW motor was taken as an example and the multi-sliced field-circuit coupled time stepping finite element method(T-S FEM)was used to analyze the axially non-uniform fundamental and harmonic field distribution characteristics at typical locations in the stator and rotor cores.The major conclusions are:firstly the skewed rotor exhibits a decrease in the harmonic copper losses caused by slot harmonic currents in the stator winding and rotor bars.Secondly,the skewed rotor shifts the non-uniform distribution of field in the axial direction,which leads to more severe saturation and an increase in iron losses.The heavier the load,the more pronounced the increase in iron losses.Furthermore,the influences of different skew angles on motor losses are studied systematically,with skew angles from 0.5 to 1.5 stator tooth pitch.It is found that the lowest total loss occurs at 0.8 stator tooth pitch,and the slot harmonics can be decreased effectively.ZHAO HaiSen LIU XiaoFang LUO YingLi CHEN WeiHua Peter BALDASSARI 2011Science China(Technological Sciences)2011,54,9:4
5Effects of exogenous ABA application on post-anthesis dry matter redistribution and grain starch accumulation of winter wheat with different staygreen characteristics显示文摘The objective of this study was to investigate whether and how exogenous abscisic acid(ABA)is involved in mediating starch accumulation in the grain and redistribution of carbohydrates during grain filling of two wheat cultivars with different staygreen characteristics.At blooming stage,plants of Wennong 6(a staygreen cultivar)and Jimai 20(control)were sprayed with10 mg L-1abscisic acid(ABA)for 3 days.The application of ABA significantly(P<0.05)increased grain filling rate,starch accumulation rate and content,remobilization of dry matters to kernels,and 1000-grain weight of the two cultivars.Exogenous ABA markedly(P<0.05)increased grain yield at maturity,and Wennong 6 and Jiami 20 showed 14.14%and 4.86%higher compared yield than the control.Dry matter accumulation after anthesis of Wennong 6 was also significantly(P<0.05)influenced by exogenous ABA,whereas that of Jimai 20 was unchanged.Application of ABA increased endogenous zeatin riboside(ZR)content 7 days after anthesis(DAA),and spraying ABA significantly increased endogenous indole-3-acetic acid(IAA)and ABA contents from 7 to 21 DAA and decreased gibberellin(GA3)content at 14 DAA,but increased GA3content from 21 to 35 DAA.The results suggested that increased yield of staygreen was due to greater starch assimilation owing to a higher filling rate and longer grain-filling duration.Dongqing Yang Yongli Luo Yingli Ni Yanping Yin Weibing Yang Dianliang Peng Zhengyong Cui Zhenlin Wang 2014The Crop Journal2014,2,Z1:3

13Performance calculation and improved model research of direct-drive permanent magnet generator based on FEM显示文摘In some control strategies of the direct-rive permanent magnet generator(DDPMG),the mathematics model is excessively simplified and some complex nonlinear characteristics,such as core saturation and cross-saturation,are generally neglected.To solve this problem,this paper utilizes the frozen element permeability method to compute the armature self-and mutual-inductance,permanent magnet d-and q-axis flux varying with d-axis and q-axis current,then an improved model is presented in which the core saturation and cross-saturation between d-axis and q-axis are considered effectively.Based on this model,the method for computing the performance of the generators is also proposed.Taking a 1.5-MW DDPMG as an example,the time-stepping finite element method(T-S FEM) is adopted to analyze the performance with no-load and loaded conditions,the results show a good agreement with the ones obtained by the improved model.Compared with the simplified model,it is demonstrated that the presented model has the high efficiency and reliability and can provide a good reference for optimization design of DDPMG and other PM motors.ZHANG Jian LI HeMing LUO YingLi DOU Na CUI XueShen 2012Science China(Technological Sciences)2012,55,8:1
14Physics-data-driven intelligent optimization for large-aperture metalenses显示文摘Metalenses have gained significant attention and have been widely utilized in optical systems for focusing and imaging,owing to their lightweight,high-integration,and exceptional-flexibility capabilities.Traditional design methods neglect the coupling effect between adjacent meta-atoms,thus harming the practical performance of meta-devices.The existing physical/data-driven optimization algorithms can solve the above problems,but bring significant time costs or require a large number of data-sets.Here,we propose a physics-data-driven method employing an“intelligent optimizer”that enables us to adaptively modify the sizes of the meta-atom according to the sizes of its surrounding ones.The implementation of such a scheme effectively mitigates the undesired impact of local lattice coupling,and the proposed network model works well on thousands of data-sets with a validation loss of 3×10^(−3).Based on the“intelligent optimizer”,a 1-cm-diameter metalens is designed within 3 hours,and the experimental results show that the 1-mm-diameter metalens has a relative focusing efficiency of 93.4%(compared to the ideal focusing efficiency)and a Strehl ratio of 0.94.Compared to previous inverse design method,our method significantly boosts designing efficiency with five orders of magnitude reduction in time.More generally,it may set a new paradigm for devising large-aperture meta-devices.Yingli Ha Yu Luo Mingbo Pu Fei Zhang Qiong He Jinjin Jin Mingfeng Xu Yinghui Guo Xiaogang Li Xiong Li Xiaoliang Ma Xiangang Luo 2023Opto-Electronic Advances2023,6,11:1

16Sequence Stratigraphy Study of the Late Quaternary Activity of the Nankou-Sunhe Fault in Its Northern Segment,Beijing显示文摘A test drilling exploration was implemented across the northern segment of the Nankou-Sunhe fault in the Beijing plain,and a combined borehole section was built by sequence stratigraphy,lithologic facies analysis,magnetic susceptibilityand absolute chronology to investigate the episodic activities of the fault since 60 ka BP. The results show that the active stages of the fault are 60 ka to 47 ka BP,36 ka to 28 ka BP,and 16 ka BP to present. Other intervals are relatively stable. The average vertical slip rate is 0.35 mm/a from 60 ka to 37 ka BP,0 mm/a from 37 ka to 32 ka BP,0.78 mm/a from 32 ka to 12 ka BP,and 0.35 mm/a since 12 ka BP. Compared with the conventional analyses on lithology and sedimentary facies,the sequence stratigraphy method has certain advantages in the studies of borehole strata comparison and episodic activity of buried faults.Zhang Shimin Wang Dandan Liu Xudong Ren Junjie Luo Minghui Zhang Guohong Zhao Guocun Wang Rui Zhang Yingli 2008Earthquake Research in China2008,22,3:0
17Nanomedicine-mediated ubiquitination inhibition boosts antitumor immune response via activation of dendritic cells显示文摘Tumor immunotherapy as a promising method for tumor treatment received tremendous attention. However, the problem of low clinical response rate still needs to be solved, especially in the poorly immunogenic tumors. The enhancement of tumor antigens presentation can effectively activate dendritic cells (DCs) and improve the tumor immunotherapy. In this work, TAK-243 as an inhibitor of the ubiquitin activating enzyme (UAE), was fabricated into cationic lipid-assisted nanoparticle (CLANTAK-243). The obtained CLANTAK-243 could act as an effective tumor immunotherapy enhancer to promote the maturation of DCs as well as antigen presentation, which obviously stimulated the T cells activation and proliferation. Such CLANTAK-243 injected intravenously could well trigger immune response to tumor cells in vivo. Importantly, mice treated with CLANTAK-243 could obtain a long immune memory effect to protect themselves from re-challenged tumor cells. Therefore, this work presented an effective immunotherapy strategy for poorly immunogenic tumor.Jilong Wang Mengwen Huang Senbiao Chen Yingli Luo Song Shen Xiaojiao Du 2021Nano Research2021,14,11:0
18The H3K9me2-binding protein AGDP3 limits DNA methylation and transcriptional gene silencing in Arabidopsis显示文摘DNA methylation,a conserved epigenetic mark,is critical for tuning temporal and spatial gene expression.The Arabidopsis thaliana DNA glycosylase/lyase REPRESSOR OF SILENCING 1(ROS1)initiates active DNA demethylation and is required to prevent DNA hypermethylation at thousands of genomic loci.However,how ROS1 is recruited to specific loci is not well understood.Here,we report the discovery of Arabidopsis AGENET Domain Containing Protein 3(AGDP3)as a cellular factor that is required to prevent gene silencing and DNA hypermethylation.AGDP3 binds to H3K9me2 marks in its target DNA via its AGD12 cassette.Analysis of the crystal structure of the AGD12 cassette of AGDP3 in complex with an H3K9me2 peptide revealed that dimethylated H3 K9 and unmodified H3 K4 are specifically anchored into two different surface pockets.A histidine residue located in the methyllysine binding aromatic cage provides AGDP3 with pH-dependent H3K9me2 binding capacity.Our results uncover a molecular mechanism for the regulation of DNA demethylation by the gene silencing mark H3K9me2.Xuelin Zhou Mengwei Wei Wenfeng Nie Yue Xi Li Peng Qijie Zheng Kai Tang Viswanathan Satheesh Yuhua Wang Jinyan Luo Xuan Du Rui Liu Zhenlin Yang Honggui La Yingli Zhong Yu Yang Jian-Kang Zhu Jiamu Du Mingguang Lei 2022Journal of Integrative Plant Biology2022,64,12:0
19Food-Borne Poisoning Accident from Amanitin Toxin in Wild Mushrooms—Xingtai City,Hebei Province,China,2023显示文摘Summary What is already known about this topic?Fatal poisonings caused by wild mushrooms containing amanita toxins pose a significant threat in the southern regions of China.These toxins primarily induce gastrointestinal symptoms initially,which are then followed by potentially life-threatening acute liver damage.What is added by this report?This report contributes to the existing knowledge on these cases of poisoning by documenting the second occurrences in Hebei Province and the first occurrences in Xingtai City.Five individuals reported consuming wild mushrooms from the same origin,and laboratory tests confirmed the presence ofα-amanitin in their blood samples.What are the implications for public health practice?This underscores the risk associated with the collection and consumption of amanita toxin-containing mushrooms in Hebei.It is important to note that the identification of toxic and non-toxic mushrooms should not solely rely on personal experience or appearance.Baopu Lv Liang Liu Hao Xiao Qingbing Meng Rui Zhang Yaqing An Yingli Jin Yu Ma Hengbo Gao Yongkai Li Qian He Yutao Zhang Changqing Liu Xiaoyan Luo Xiaomin Xu Fenshuang Zheng Yingping Tian Hongshun Zhang Dongqi Yao 2024China CDC weekly2024,6,3:0
20Research Article Ferric iron coordinated cisplatin prodrug reprograms the immunecold tumor microenvironment through tumor hypoxia relief for enhanced cancer photodynamic-immunotherapy显示文摘The microenvironment of hypoxia and immune-cold limits the therapeutic outcomes of immune checkpoint blockade(ICB)therapy in solid tumors.It is important and imperative to search new strategies to relieve tumor hypoxia and reverse immunosuppression of cold tumors.In this study,the oxygen(O_(2))self-replenishing nano-enabled coordination platform can be used to induce potent antitumor immune response in cold tumors.The nanoplatform can produce O_(2)by catalyzing hydrogen peroxide(H_(2)O_(2))in tumor site effectively,showing excellent photodynamic therapy(PDT)performance.Meanwhile,it can further trigger immunogenic cell death(ICD),enhance T cell infiltration,reverse immunosuppression,and reprogram the immune-cold tumor microenvironment.In vitro and in vivo results demonstrate that the nanoplatform has potential for eradicating tumors and long-term immunological memory effect.The nanoplatform opens up a strategy for reprograming the immunosuppressive microenvironment in cold tumors.Yinchu Ma Yingli Luo Xinfeng Tang Wei Jiang Hongjun Li Jilong Wang 2023Nano Research2023,16,7:0
