| 1 | Coning motion stability of wrap around fin rockets显示文摘Both the asymptotical stability criterion and the bounded stability criterion of the coning motion for wrap around fin(WAF) rockets are proposed through the analy-sis of coning motion equations,which can be easily used to determine the exis-tence of the coning motion during the rocket design. The correctness of the crite-rions is verified by mathematical simulation examples of a WAF rocket with differ-ent setting angles. It is also found that the setting angle of WAF has great effects on the rolling moment and side moment of the rocket. | MAO XueRui YANG ShuXing XU Yong | 2007 | Science China(Technological Sciences)2007,50,3: | 7 |
| 2 | Construction of a high-density mutant population of Chinese cabbage facilitates the genetic dissection of agronomic traits显示文摘Chinese cabbage(Brassica rapa ssp.pekinensis)is an economically important vegetable crop throughout the world,especially in Asia.High-quality genome sequences are available for Chinese cabbage,but gene functional studies remain challenging.To promote functional genomic studies of Chinese cabbage,we generated an ethyl methane sulfonate(EMS)mutant population of~8000 M_(2) plants using the double haploid inbred line A03 as the parent.The genome of A03 was sequenced and used as a reference for high-throughput functional characterization of gene mutations at the whole-genome level.A total of 300 M_(2) to M_(5) EMS mutants were phenotypically screened and then sequenced,revealing 750629 SNPs and 46272 InDel mutations that cover 98.27%of all predicted genes in the A03 genome.A forward-genetics approach was successfully used to identify two genes with chloroplast-related functions that are responsible for the yellow leaf mutant trait.A reverse-genetics approach was also used to identify associations between mutations in five genes of the glucosinolate biosynthetic pathway and variations in glucosinolate content of the mutant plants.In addition,we built the Chinese cabbage EMS mutation database(CCEMD,www.bioinformaticslab.cn/EMSmutation/home)to increase the usability of this mutant population resource.In summary,we performed large-scale screening of a heading Chinese cabbage EMS mutant collection at the phenotypic and genotypic levels,which will facilitate gene mining of Chinese cabbage and might also be useful for the study of other Brassica crops. | Xiaoxue Sun Xing Li Yin Lu Shan Wang Xiaomeng Zhang Kang Zhang Xiangjie Su Mengyang Liu Daling Feng Shuangxia Luo Aixia Gu Yu Fu Xueping Chen Shuxin Xuan Yanhua Wang Donghui Xu Shumin Chen Wei Ma Shuxing Shen Feng Cheng Jianjun Zhao | 2022 | Molecular Plant2022,15,5: | 1 |

The Phosphorus-like 112Sn35+ ions were injected into the CSRm at an energy of 3.7 MeV/u with a typical current of 50 eA, and the momentum spread of the ion beam is 210?4 after several seconds of cooling. | Xu Xin Wang Shuxing Zhu Linfan Huang Zhongkui Ma Xinwen Wen Weiqiang Wang Hanbing Chuai Xiaoya Dou Lijun Zhu Xiaolong Zhao Dongmei Yuan Youjin Mao Lijun Li Jie Ma Xiaoming Yan Tailai Yang Jiancheng Xia Jiawen | 2015 | IMP & HIRFL Annual Report2015,,1: | 0 |
| 5 | Hormones and carbohydrates synergistically regulate the formation of swollen roots in a Chinese cabbage translocation line显示文摘The genus Brassica contains a rich diversity of species and morphological types,including leaf,root,and oil crops,all of which show substantial phenotypic variation.Both Chinese cabbage and cabbage are typical leaf-type crops with normal roots.We created translocation lines based on interspecific crosses between Chinese cabbage and cabbage and identified qdh225,which exhibited a swollen-root phenotype.The swollen root of qdh225 contained a large number of granular substances,and the formation of its irregular morphological tissue was caused by a thickening of the phloem.Transcriptomic and metabolomic data suggested that differential expression of genes encoding nine types of enzymes involved in starch and sucrose metabolism caused changes in starch synthesis and degradation in the swollen root.These genes jointly regulated sucrose and starch levels,leading to significant enrichment of starch and soluble proteins in the swollen root and a reduction in the content of soluble sugars such as d-glucose and trehalose 6-phosphate.A significant increase in auxin(IAA)and abscisic acid(ABA)contents and a decrease in gibberellin(GA)content in the swollen root likely promoted the differential expression of genes associated with hormone signal transduction,thereby regulating the development of the swollen root.Taken together,our data suggest that accumulation of IAA and ABA and reduction in GA promote swollen root formation by regulating hormone-mediated signaling,leading to a thickening of phloem,root enlargement,and substantial accumulation of starch and soluble proteins.The latter provide materials,energy,and nutrient sources for the development of swollen roots. | Xiaojing Ren Wei Ma Shuxin Xuan Dandan Li Yanhua Wang Yuanchao Xu Daling Feng Jianjun Zhao Xueping Chen Shuangxia Luo Shuxing Shen Aixia Gu | 2023 | Horticulture Research2023,10,8: | 0 |
| 6 | Miniaturized retractable thin-film sensor for wearable multifunctional respiratory monitoring显示文摘As extremely important physiological indicators,respiratory signals can often reflect or predict the depth and urgency of various diseases.However,designing a wearable respiratory monitoring system with convenience,excellent durability,and high precision is still an urgent challenge.Here,we designed an easy-fabricate,lightweight,and badge reel-like retractable selfpowered sensor(RSPS)with high precision,sensitivity,and durability for continuous detection of important indicators such as respiratory rate,apnea,and respiratory ventilation.By using three groups of interdigital electrode structures with phase differences,combined with flexible printed circuit boards(FPCBs)processing technology,a miniature rotating thin-film triboelectric nanogenerator(RTF-TENG)was developed.Based on discrete sensing technology,the RSPS has a sensing resolution of 0.13 mm,sensitivity of 7 P·mm^(−1),and durability more than 1 million stretching cycles,with low hysteresis and excellent anti-environmental interference ability.Additionally,to demonstrate its wearability,real-time,and convenience of respiratory monitoring,a multifunctional wearable respiratory monitoring system(MWRMS)was designed.The MWRMS demonstrated in this study is expected to provide a new and practical strategy and technology for daily human respiratory monitoring and clinical diagnosis. | Chengyu Li Zijie Xu Shuxing Xu Tingyu Wang Siyu Zhou Zhuoran Sun Zhong Lin Wang Wei Tang | 2023 | Nano Research2023,16,9: | 0 |
| 7 | 重离子冷却储存环CSRm上的类铍^(40)Ar^(14)+离子的双电子复合和三电子复合显示文摘Electron-ion recombination of Be-like ^(40)Ar^(14)+has been measured by employing the electron-ion merged-beams method at the cooler storage ring CSRm.The measured absolute recombination rate coefficients for collision energies from 0 to 60 eV are presented in Fig.1,covering all dielectronic recombination(DR)resonances associated with 2s^(2)→2s2p core transitions.In addition,strong trielectronic recombination(TR)resonances associated with 2s^(2)→2p^(2) core transitions were observed.Both DR and TR processes lead to series of peaks in the measured recombination spectrum,which have been identified by the Rydberg formula.Theoretical calculations of recombination rate coefficients were performed using the state-of-the-art multi-configuration Breit-Pauli(MCBP)atomic structure code AUTOSTRUCTURE to compare with the experimental results.The plasma rate coefficients for DR+TR of Ar14+were deduced from the measured electron-ion recombination rate coefficients in the temperature range from 10^(3) to 10^(7) K,and compared with calculated data from the literature. | Huang Zhongkui Wen Weiqiang Wang Hanbing Xu Xin Zhu Linfan Wang shuxing Dou Lijun Zhu Xiaolong Yao ke Xu Tianheng Mao Lijun Li Jie Yang Jiancheng Yuan Youjinand Ma Xinwen | 2017 | IMP & HIRFL Annual Report2017,,1: | 0 |
| 8 | 3-2 Dielectronic Recombination of Be-like 40Ar14+at the CSRm显示文摘The total recombination rate coefficients of Be-like 40Ar14+ions have been measured by employing the electron-ion merged-beams technique at the heavy ion storage ring CSRm at IMP.Fig.1 shows the recombination spectrum for electron energy from 0 to 58 eV in the center-of-mass frame.The resonant capture,involving the core excitation of an electron and two electrons,which is termed dielectronic recombination(DR)and trielectronic recombination(TR)individually and leads to series of peaks,have been preliminarily identified by extending downward in energy from their series limits with the Rydberg formula[1]. | Huang Zhongkui Wen Weiqiang Wang Hanbing Dou Lijun Zhu Xiaolong Xu Xin Zhu Linfan Wang Shuxing Xu Weiqing Yao ke Xu Tianheng YangYang Mao Lijun Li Jie Yang Jiancheng Yuan Youjin Ma Xinwen | 2016 | IMP & HIRFL Annual Report2016,,1: | 0 |
| 9 | 3-11 Dielectronic Recombination of 56Fe^17+at the CSRm显示文摘The ionization and heating of the media surrounding accretion-powered compact sources,such as cataclysmic variables,X-ray binaries,and active galactic nuclei,are dominated by photoionization.Theoretical models of photo ionized gases show that the ionization structure is determined by photoionization balanced by radiative recombination(RR)and dielectronic recombination(DR).At low electron temperature existing in photo ionized gases with cosmic abundances,DR proceeds primarily via nlj→nl′j′excitations of core electrons(Δn=0). | Khan Nadir Huang Zhongkui Wen Weiqiang Xu Xin Wang Shuxing Wang Hanbing Dou Lijun Zhu Xiaolong Mao Lijun Li Jie Ma Xiaoming Yang Jiancheng Yuan Youjin Zhu Linfan Ma Xinwen | 2016 | IMP & HIRFL Annual Report2016,,1: | 0 |
