| 1 | Location and PCR analysis of catabolic genes in a novel Streptomyces sp. DUT_AHX capable of degrading nitrobenzene显示文摘A novel strain of Streptomyces sp.DUT_AHX was isolated from sludge contaminated with nitrobenzene and identified on the basis of physiological and biochemical tests and 16S ribosomal DNA (rDNA) sequence analysis.The optimal degradation conditions were as follows:temperature 30℃,pH 7.0-8.0,shaking speed 150-180 r/min,and inocula 10%(V/V).The strain,which possessed a partial reductive pathway with the release of ammonia,was also able to grow on mineral salts basal (MSB) medium plates with 2-aminophenol, ph... | Al Haixin Zhou Jiti Lv Hong Wang Jing Guo Hanb Liu Guangfei Qu Yuanyuan | 2008 | Journal of Environmental Sciences2008，20，7： | 7 |
| 2 | 4-6 Measurement of the Ratio of C3+ and O4+ Ions Produced by ECR Source to Prepare a Laser Cooling Experiment at Storage Rings显示文摘The cooling of heavy ions can provide high-quality beams that are especially important for high-precisionexperimental nuclear and atomic physics. The laser cooling of relativistic C3+ ion beams at the experimental coolerstorage ring (CSRe) is being currently prepared at Institute of Modern Physics (IMP) in Lanzhou. An electroncyclotron resonance ion source (ECRIS) will be used to produce C3+ ion beams. Meanwhile, O4+ ions could alsobe produced due to residual gas because of the same mass-to-charge ratio. Therefore, both C3+ and O4+ ion beamswill be injected and circulate in a storage ring during the laser cooling experiment at the same time. A higher ratioof C3+ ions will lead to a better result for the laser cooling experiment. | Zhu Xiaolong Wen Weiqiang Ma Xinwen Li Jinyu Feng Wentian Zhang Ruitian Yan Shuncheng Guo Dalong Hai Bang Qian Dongbin Zhang Pengju Xu Shenyue Zhao Dongmei Yang Jie Zhang Dacheng Li Bin Gao Yong Huang Zhongkui Wang Hanbing | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 3 | Ne^(8+)重离子碰撞氩二聚体碎裂中的取向效应研究显示文摘The experiment was carried out using the Reaction Microscope mounted at the 320 kV platform for multidisciplinary research with highly charged ions at the Institute of Modern Physics,CAS[1,2].For reaction channel of(Ar2)^(2+)→Ar^(+)+Ar^(+),the kinetic energy release(KER)distribution clearly shows two peaks.The left peak locates at 3.7 eV approximately,and the right one lies at about 5.3 eV.From the classical reflection approximation KER/(Z1-Z2)=R,the internuclear distance R can be deduced.We find that the corresponding internuclear distance of the left peak is 3.8˚A,which is the equilibrium internuclear distance of the Ar2 dimer.This indicates that coulomb explosion takes place immediately after the double ionization process,without the involvement of the geometry change of the cluster ion.Therefore,the left peak dominantly arises from two-site double ionization. | Zhu Xiaolong Yan Shuncheng Feng Wentian Ma Xinwen Chuai Xiaoya Guo Dalong Gao Yong Zhang Ruitian Zhang Pengju Zhang Shaofeng Zhao Dongmei Xu Shenyue Wang Hanbing Huang Zhongkui Qian Dongbin | 2018 | IMP & HIRFL Annual Report2018，，1： | 0 |
| 4 | Classification of Domestic Refuse in Medical Institutions Based on Transfer Learning and Convolutional Neural Network显示文摘The problem of domestic refuse is becoming more and more serious with the use of all kinds of equipment in medical institutions.This matter arouses people’s attention.Traditional artificial waste classification is subjective and cannot be put accurately;moreover,the working environment of sorting is poor and the efficiency is low.Therefore,automated and effective sorting is needed.In view of the current development of deep learning,it can provide a good auxiliary role for classification and realize automatic classification.In this paper,the ResNet-50 convolutional neural network based on the transfer learning method is applied to design the image classifier to obtain the domestic refuse classification with high accuracy.By comparing the method designed in this paper with back propagation neural network and convolutional neural network,it is concluded that the CNN based on transfer learning method applied in this paper with higher accuracy rate and lower false detection rate.Further,under the shortage situation of data samples,the method with transfer learning and ResNet-50 training model is effective to improve the accuracy of image classification. | Dequan Guo Qiao Yang Yu-Dong Zhang Tao Jiang Hanbing Yan | 2021 | Computer Modeling in Engineering & Sciences2021，，5： | 0 |

| 6 | Challenges and Responses of Left-Behind Elderly and Children in Rural China Amid the New Population Development Stage显示文摘The disparate economic growth in China has compelled numerous adults from rural areas to migrate to cities in search of more lucrative employment prospects(1).In the 7th National Census,it was reported that the floating population totaled 375,816,759,accounting for approximately 26.00%of the overall population.Such migratory patterns often result in leaving behind vulnerable groups,particularly children and older adults,in rural regions.Given the inadequately established care systems,these groups are particularly susceptible and have consistently been at the forefront of social security concerns in China(2). | Dianqi Yuan Peisen Yang Hanbing Yang Huameng Tang Chao Guo | 2023 | China CDC weekly2023，5，27： | 0 |
| 7 | 3-1 Probing the Geometry of Ar2N2 Cluster by Heavy Ions Impact显示文摘The molecular complexes play an important role in planet’s atmosphere and chemical reactions of astrophysics.The investigation of geometry configurations for molecular complexes is an important subject both in experimental and theoretical aspects.As a prototype molecular system,the investigation of geometry configuration of van der Waals cluster Ar2N2 attracts considerable attention recently.The different equilibrium configurations of Ar2N2 cluster were reported by experiments as linear conformation[1;2]and theoretical calculations as linear or spatial X-shaped conformations[3-6]. | Zhu Xiaolong Yan Shuncheng Feng Wentian Guo Dalong Gao Yong Zhang Ruitian Zhang Shaofeng Wang Hanbing Huang Zhongkui Zhang Min Hai Bang Zhao Dongmei Wen Weiqiang Zhang Pengjun Qian Dongbin Ma Xinwen | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
