| 1 | RNA-Seq Study Reveals AP2-Domain-Containing Signalling Regulators Involved in Initial Imbibition of Seed Germination in Rice显示文摘A number of internal signals are required for seed germination.However,the precise signalling responses in the initial imbibition of seed germination are not yet fully understood in rice.In this study,the RNA sequencing(RNA-Seq)approach was conducted in 8 h imbibed seeds to understand the signalling responses in the initial imbibition of rice seed germination.A total of 563 differentially expressed genes(DEGs)with at least 4-fold change were identified in 8 h imbibed seeds compared to dry seeds.MapMan analysis revealed that the majority of signalling response-related DEGs were hormone-and transcription factor-related genes,in which the largest number of DEGs belong to the AP2-domain-containing regulators,and their expressions were significantly induced in the initial imbibition of seed germination in rice.Moreover,at least five AP2-domain-containing transcription factor OsDREBs were identified in the initial imbibition of rice seed germination,and the expressions of 251 DEGs were putatively regulated by OsDREBs through the dehydration-responsive element(DRE)cis-element assay.It suggested that the OsDREBs might play important roles in the regulation of initial seed imbibition in rice.The identified genes provide a valuable resource to study the signalling regulation of seed germination in the future. | HE Yongqi ZHAO Jia FENG Defeng HUANG Zhibo LIANG Jiaming ZHENG Yufei CHENG Jinping YING Jifeng WANG Zhoufei | 2020 | Rice science2020，27，4： | 2 |
| 2 | 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 |
| 3 | Origin, dissemination and entry of the pandemic Zika viruses显示文摘Zika 病毒(ZIKV ) 是打扫了大多数西方的半球的以前忽视,却最新新兴的 zoonotic 病原体。意外注意在新生儿在在 2015 ZIKV 散布到巴西和美国的炸药和它的稀罕关联引起了世界范围的谎言到头小畸型,提起对公共健康的严肃的挑战。我们证明起源和这些流行 ZIKA 的快传播孤立。种系发生的分析表明最新新兴的 ZIKV 孤立的所有属于亚洲美国人的系。ZIKV E 表面蛋白质的结构的分析建议它可能采用类似的入口机制到另外的 Flavi 病毒相似登革热病毒和韦斯特尼罗河病毒的。 | Huimin Zhang Swaminath Srinivas Defeng Li Youjun Feng | 2016 | Science Bulletin2016，61，10： | 1 |

| 5 | A hypothesis of 3D rainfall tomography using satellite signals显示文摘The attenuation of microwave signals due to rainfall,known as rain attenuation,can be used to measure rain.Similar to using X-ray to carry out human-body CT scans,the microwave signals of low earth and/or medium earth orbit satellites are proposed for carrying out 3D(Three Dimensional)rainfall tomography in this paper.The proposed method will not only complement the three major rain measurement methods in use today(i.e.rain gauge,weather radar,and weather satellite)but also potentially achieve 3D rainfall measurements with precision and coverage unachievable before.Along with the deployment of low earth orbit satellite constellations(e.g.the OneWeb constellation)for global broadband Internet services,small satellite receivers of the size of a pizza box may be used to achieve 3D rainfall tomography anywhere on the Earth,thereby paving the way for many practical applications and atmospheric research that are associated with rainfall. | HUANG Defeng(David) XU Lu FENG Xuxiang WANG Wanyu | 2016 | Journal of Communications and Information Networks2016，1，1： | 1 |
| 6 | Preparation and Gas Sensing Performance of Hierarchical Porous ZnO-based Materials with Sunflower Rods as a Biological Template显示文摘A graded porous structure SnO2/ZnO composite was prepared with sunflower rods as a biological template. The prepared samples were subjected to phase analysis by scanning electron microscopy(SEM), transmission electron microscopy(TEM), X-ray diffractiometry(XRD) and X-ray photoelectron spectroscopy(XPS).ZnO sample was a pure phase of hexagonal wurtzite, and the template had been completely removed. The surface of the sample presented a honeycomb-like structure of a sunflower rod template, which was formed by interconnecting the porous channels, and had a smaller average size and exhibited n-n heterojunction at tlie n-type ZnO interface. Compared with that of pure ZnO, the response of the hierarchical porous structure SnO2/ZnO composite to 100 mg/L w-butanol reached a maximiuTi of 40.61 at 240℃, about 2.7 times higher than that of pure ZnO. Its response time and recovery time are 6 and 3 s, respectively, which are also better than those of pure ZnO. SnO2/ZnO composite exhibits good gas selectivity, which is related to the improvement of the structure and the forming of n-n heterojunctions of the material. | WANG Bowei ZENG Qingrui CHEN Shu YUE Tongtong HAN Bing FENG Wei YANG Defeng | 2019 | Chemical Research in Chinese Universities2019，35，5： | 0 |
