| 1 | MULTI-TILLERING DWARF1, a new allele of BRITTLE CULM 12, affects plant height and tiller in rice显示文摘Plant height and tillering are crucial factors determining rice plant architecture and influencing rice grain production. In this study, multi-tillering dwarf1(mtd1), a stable multi-tiller and dwarf mutant, was screened from the ethylmethane sulfonate-treated japonica rice variety Wuyunging7. Compared with the wild type, mtd1 mutant exhibited pleiotropic phenotypes, including dwarfism, more tillers, brittle culms and delayed heading date.By employing map-based cloning strategy, the gene MTD1 was finally mapped to an approximately 66-kb region on the short arm of chromosome 9. Sequencing results showed that the gene LOC_Os09g02650(BC12) in mtd1 mutant had a single nucleotide substitution(G to A), which generated a premature translation stop. Over-expressing MTD1/BC12 coding sequence rescued all the phenotypes of mtd1 mutants including plant height and tillers, which confirms that BC12 is the mutated gene in mtd1 mutant.Quantitative reverse transcription-PCR analysis showed that MTD1/BC12 could negatively regulate the expression of MONOCULM 1, IDEAL PLANT ARCHITECTURE1 and Tillering and Dwarf 1, and control rice tillering. Remarkably, a-amylase activity analysis and gibberellic acid(GA)treatment showed that the dwarf phenotype of mtd1 mutant was dependent on GA biosynthesis pathway. These results facilitated to further uncover the molecular mechanism of the growth and development in rice. | Haiping Yu Deyong Ren Yangzhou Zhu Jiangmin Xu Yuexing Wang Ruifang Liu Yunxia Fang Zhenyuan Shi Jiangjie Pan Mei Lu Bojun Ma Jiang Hu Yuchun Rao | 2016 | Science Bulletin2016，61，23： | 3 |
| 2 | A Secure and Cost-Effective Training Framework Atop Serverless Computing for Object Detection in Blasting显示文摘The data analysis of blasting sites has always been the research goal of relevant researchers.The rise of mobile blasting robots has aroused many researchers’interest in machine learning methods for target detection in the field of blasting.Serverless Computing can provide a variety of computing services for people without hardware foundations and rich software development experience,which has aroused people’s interest in how to use it in the field ofmachine learning.In this paper,we design a distributedmachine learning training application based on the AWS Lambda platform.Based on data parallelism,the data aggregation and training synchronization in Function as a Service(FaaS)are effectively realized.It also encrypts the data set,effectively reducing the risk of data leakage.We rent a cloud server and a Lambda,and then we conduct experiments to evaluate our applications.Our results indicate the effectiveness,rapidity,and economy of distributed training on FaaS. | Tianming Zhang Zebin Chen Haonan Guo Bojun Ren Quanmin Xie Mengke Tian Yong Wang | 2024 | Computer Modeling in Engineering & Sciences2024，139，5： | 0 |
| 3 | Applicable scope of oxygen-reduced air flooding and the limit of oxygen content显示文摘The mechanisms of oxygen-reduced air flooding(ORAF)and the explosion limit and the corrosion control approaches were studied based on the pilots of oxygen-reduced air flooding(ORAF)in the Dagang,Changqing and Daqing oil fields in China.On the foundation of indoor investigations and pilots,the explosion limits,oxygen reduction limits and corrosion control approaches were clarified.When the temperature of reservoir is equal to and higher than 120℃,there is a violent reaction between oxygen and crude oil,that means the effect of low temperature oxidation would be fully taken use of to enhance oil recovery by air flooding directly;nitrogen dominated immiscible flooding with oxygen-reduced air should be applied in cases where reservoir temperature is below 120℃ with little oxygen consumption and little heat generated.The oxygen-reduced air flooding is suitable for 3 types of reservoirs:low permeability reservoir,water flooding development reservoir of high water-cut and high temperature and high salinity reservoir.In the process of development,in order to ensure safety,the oxygen reduction limits should be controlled fewer than 10%,while oxygen-reduced air can obviously reduce the corrosion rate of pipes;The surface pipelines and injection wells don’t need to consider about oxygen corrosion with no water,special materials and structure of pipe or corrosion inhibitor can be applied to the surface pipelines and injection wellbores with water.Air/oxygen-reduced air is a low-cost displacement medium and it could be applied in many special conditions of low permeability reservoir for energy supplement,huff and puff and displacement,that means oxygen-reduced air flooding has become the most potential strategic technology in 20 years. | LIAO Guangzhi YANG Huaijun JIANG Youwei REN Shaoran LI Dangguo WANG Liangang WANG Zhengmao WANG Bojun LIU Weidong | 2018 | Petroleum Exploration and Development2018，45，1： | 0 |
| 4 | Residue and Safety Use of Emamectin Benzoate in Ginger显示文摘[Objective]The paper was to guide scientific and rational use of emamectin benzoate in ginger.[Method]A field experiment was conducted to determine residue and degradation dynamics and final residue of emamectin benzoate in ginger.The residue of emamectin benzoate in ginger was determined by high performance liquid chromatography-mass spectrometry(HPLC-MS/MS).[Result]The half-life of emamectin benzoate in ginger was 2.2-3.4 d.As 5%emamectin benzoate WDG was sprayed on ginger at 7.5 and 11.25 g·a.i/hm^2 for consecutive 1-2 times,the residues of emamectin benzoate in ginger harvested at 7,14 and 21 d post spraying were lower than the quantitative limit of the method(0.01 mg/kg),and were lower than the stipulation in Japan as well(0.1 mg/kg).[Conclusion]It is safe to use emamectin benzoate in ginger with the harvest interval of 7 d according to the recommended dose. | Feng Yizhi Zhang Aijuan Liang Lin Lin Dongsen Ren Yupeng Ma Xingang Li Wenping Zuo Bojun | 2019 | Plant Diseases and Pests2019，10，4： | 0 |
