| 1 | Clustering by Fast Search and Find of Density Peaks with Data Field显示文摘A clustering algorithm named 'Clustering by fast search and find of density peaks' is for finding the centers of clusters quickly. Its accuracy excessively depended on the threshold, and no efficient way was given to select its suitable value, i.e., the value was suggested be estimated on the basis of empirical experience. A new way is proposed to automatically extract the optimal value of threshold by using the potential entropy of data field from the original dataset. For any dataset to be clustered, the threshold can be calculated from the dataset objectively instead of empirical estimation. The results of comparative experiments have shown the algorithm with the threshold from data field can get better clustering results than with the threshold from empirical experience. | WANG Shuliang WANG Dakui LI Caoyuan LI Yan DING Gangyi | 2016 | Chinese Journal of Electronics2016，25，3： | 60 |

| 3 | Seed Selection for Data Offloading Based on Social and Interest Graphs显示文摘The explosive growth of mobile data demand is becoming an increasing burden on current cellular network.To address this issue,we propose a solution of opportunistic data offloading for alleviating overloaded cellular traffic.The principle behind it is to select a few important users as seeds for data sharing.The three critical steps are detailed as follows.We first explore individual interests of users by the construction of user profiles,on which an interest graph is built by Gaussian graphical modeling.We then apply the extreme value theory to threshold the encounter duration of user pairs.So,a contact graph is generated to indicate the social relationships of users.Moreover,a contact-interest graph is developed on the basis of the social ties and individual interests of users.Corresponding on different graphs,three strategies are finally proposed for seed selection in an aim to maximize overloaded cellular data.We evaluate the performance of our algorithms by the trace data of real-word mobility.It demonstrates the effectiveness of the strategy of taking social relationships and individual interests into account. | Ying Li Jianbo Li Jianwei Chen Minchao Lu Caoyuan Li | 2018 | Computers, Materials & Continua2018，，12： | 1 |
| 4 | Primary Hodgkin disease of the spine could mimic eosinophilic granuloma initially显示文摘Primary Hodgkin disease (HD) of bone is rare.The recognition on it is relatively confined.Both cases arising in male adults were suspected to be Potts disease (spinal tuberculosis) on imaging,and pathologic misdiagnosed initially.The clinical situations rapidly aggravated.The pathomorphology was remarkable malignant changed.They shared similar process in clinical,radiological and diagnostic process and could be representative.We retrospectively analyzed correlative results of them and review points of distinction from other disease entities that might be confused with it. | GENG Yan-hua WANG Chang-xing TAN Yan-bin XU Xiao-ming CAOYuan LIU Zi-yu LI Yan-qing | 2013 | Chinese Medical Journal2013，，18： | 1 |
| 5 | An acid-base responsive linear-cyclic polymer rotaxane molecular shuttle with fluorescence signal output显示文摘The preparation of intelligent-responsive materials with controllable topology structure has long been a significant objective for chemists in the field of materials science. In this paper, we designed and prepared a linear-cyclic reversible topological structure polymer based on the bistable [1]rotaxane molecular shuttle. A ferrocene-functionalized [1]rotaxane and naphthalimide fluorophore group are introduced into the both ends of the polymer, which exhibit distance-induced photo-electron transfer effect. The structural transformation between linear and cyclic state of polymer is demonstrated by simple acid-base stimuli, accompanying visual fluorescence changes. The transformation process was characterized by 1H NMR spectra and fluorescence spectra. This work provides a novel strategy to construct functionalized polymers with topological structure. | Zhanqi Cao Dongpu Wu Mengzhen Li Fan Yang Zhikai Li Wankai An Song Jiang Xin Zheng Caoyuan Niu Dahui Qu | 2022 | Chinese Chemical Letters2022，33，3： | 0 |
