| 1 | Data-driven optimal cooperative adaptive cruise control of heterogeneous vehicle platoons with unknown dynamics显示文摘This paper considers the cooperative adaptive cruise control(CACC)problem of heterogeneous vehicle platoons and proposes a data-driven optimal CACC approach for the heterogeneous platoon with unknown dynamics.To cope with the unknown dynamics of the vehicle CACC platoon system,the adaptive dynamic programming is used to design an online iteration policy for optimal CACC of the platoon.Using the predecessor-following topology,the CACC controllers are computed by employing the desired spacing errors,relative velocities,and accelerations of the vehicles.The stability of the closed-loop CACC system and the iteration algorithm are presented.Furthermore,the string stability of the platoon with the CACC system is established in terms of the acceleration transfer function between adjacent vehicles in frequent domain.Finally,the effectiveness of the proposed method is verified in two complex scenarios of varying speed cruise. | Xiulan SONG Feng DING Feng XIAO Defeng HE | 2020 | Science China(Information Sciences)2020，63，9： | 2 |
| 2 | Properties of mouse retinal ganglion cell dendritic growth during postnatal development显示文摘The property of dendritic growth dynamics during development is a subject of intense interest.Here,we investigated the dendritic motility of retinal ganglion cells (RGCs) during different developmental stages,using ex vivo mouse retina explant culture,Semliki Forest Virus transfection and time-lapse observations.The results illustrated that during development,the dendritic motility underwent a change from rapid growth to a relatively stable state,i.e.,at P0 (day of birth),RGC dendrites were in a highly active state,whereas at postnatal 13 (P13) they were more stable,and at P3 and P8,the RGCs were in an intermediate state.At any given developmental stage,RGCs of different types displayed the same dendritic growth rate and extent.Since the mouse is the most popular mammalian model for genetic manipulation,this study provided a methodological foundation for further exploring the regulatory mechanisms of dendritic development. | YANG XiuLan,SHI XiangMing & HE ShiGang State Key Laboratory of Brain and Cognitive Sciences,Institute of Biophysics,Chinese Academy of Sciences,Beijing 100101,China | 2010 | Science China(Life Sciences)2010，53，6： | 2 |
| 3 | Straw mulch-based no-tillage improves tillering capability of dryland wheat by reducing asymmetric competition between main stem and tillers显示文摘The moisture-conserving effect of straw mulch-based no-tillage(SMNT)is expected to increase fertile spikes and grain yield in environments with rainfall less than 200 mm.However,the mechanisms under-lying the positive effect of SMNT on wheat tillering are not fully elucidated.A split-plot experiment was designed to investigate the combined effects of SMNT and cultivars on tillering of dryland wheat grown under both dry and favorable climates.Application of SMNT to a cultivar with 1-2 tillers exploited both tillering and kernel-number plasticity,increasing the mean grain yield by 20.5%.This increase was attrib-uted primarily to an increased first-tiller emergence rate resulting from increased N uptake,leaf N con-tent,and N remobilization from tillers to their grain.The second and third tillers,as transient sinks,contributed to the tiller survival rate,which depends on tiller leaf number.The increased total N uptake by SMNT also increased the dry mass yield of tillers and the C:N ratio,reducing the asymmetric compe-tition between main stem and tillers.Owing to these beneficial effects,reduced mitogen-activated pro-tein kinase(MAPK)and abscisic acid signals were observed under SMNT,whereas indole-3-acetic acid(IAA)signals and genes involved in DNA replication and mismatch repair were increased.These signals activated three critical transcription factors(the calmodulin-binding transcription activator,GRAS domain,and cysteine-2/histidine-2 family)and further increased rapid drought response and tiller main-tenance after stem extension.Phenylpropanoid biosynthesis,sphingolipid biosynthesis,and galactose metabolism were most relevant to increased tillering under SMNT because of their critical role in drought response and lignin biosynthesis.Our results suggest that straw mulch-based no-tillage activates rapid drought response and improved wheat tillering by coordinating root N uptake,N remobilization,and asymmetric competition between main stem and tillers. | Hongkun Yang Yun Xiao Peng He Dailong Ai Qiaosheng Zou Jian Hu Qiong Liu Xiulan Huang Ting Zheng Gaoqiong Fan | 2022 | The Crop Journal2022，10，3： | 2 |
| 4 | Generation of transgenic wheat resistant to wheat yellow mosaic virus and identification of gene silence induced by virus infection显示文摘The plasmid containing the promoter Actl, the coat protein (cp) gene of wheat yellow mosaic virus (WYMV) and the selectable bar gene, was delivered via particle bombardment, directly into immature embryos of a wheat culti-vars. PCR and PCR-RFLP were employed to screen the existence of the cp gene in T0 and T1 generations. Seeds from the positive T1 plants were sowed in fields heavily contaminated with WYMV to detect their resistance. In field trial of virus infection, one of the transgenic wheat lines, P8-T2, exhibited highly disease-resistance. Western blot and RT-PCR analysis showed that the expression level of cp gene in the resistant transgenic line was reduced greatly compared to those susceptible to WYMV infection. This provided evidence to presume that the resistance obtained by the transgenic wheat line was stimulated by the mechanism of the virus induced gene silencing. | DONG Jin HE Zhentian HAN Chenggui CHEN Xiulan ZHANG Lingdi LIU Weihua HAN Yuepeng WANG Jinrong ZHAI Yafeng YU Jialin LIU Yi XIAO Yueyan | 2002 | Chinese Science Bulletin2002，47，17： | 2 |

| 14 | Gene cloning and sequence analysis of the cold-adapted chaperones DnaK and DnaJ from deep-sea psychrotrophic bacterium Pseudoalteromonas sp. SM9913显示文摘Pseudoalteromonas sp.SM9913 is a phychrotrophic bacterium isolated from the deep-sea sediment.The genes encoding chaperones DnaJ and DnaK of P.sp.SM9913 were cloned by normal PCR and TAIL-PCR(GenBank accession Nos DQ640312,DQ504163).The chaperones DnaJ and DnaK from the strain SM9913 contain such conserved domains as those of many other bacteria,and show some cold-adapted characteristics in their structures when compared with those from psychro-,meso-and themophilic bacteria.It is indicated that chaperones DnaJ and DnaK of P.sp.SM9913 may be adapted to low temperature in deep-sea and function well in assisting folding,assembling and translocation of proteins at low temperature.This research lays a foundation for the further study on the cold-adapted mechanism of chaperones DnaJ and DnaK of cold-adapted microorganisms. | ZHAO Dianli CHEN Xiulan HE Hailun SHI Mei ZHANG Yuzhong | 2007 | Acta Oceanologica Sinica2007，26，6： | 1 |
