| 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 |
| 2 | Augmented reality registration algorithm based on nature feature recognition显示文摘This paper presents an improved key frame based augmented reality registration algorithm for real-time motion tracking in outdoor environment. In such applications, wide-baseline feature matching is a critical problem. In this paper, we apply randomized tree method to match key points extracted from the input image to those key frames as a classification problem. Extended Kalman filter is also utilized for jitter correction. A video see-through mobile augmented reality system is built for the on-site digital reconstruction of Yuanmingyuan Garden. Experimental results demonstrate that this algorithm is real-time, robust and effective for outdoor tracking. | CHEN Jing WANG YongTian GUO JunWei LIU Wei LIN JingDun XUE Kang LIU Yue DING GangYi | 2010 | Science China(Information Sciences)2010，53，8： | 11 |

| 7 | Autophagic dysfunction of β cell dysfunction in type 2 diabetes,a double-edged sword显示文摘Diabetes is an age-related disease,most of which is type 2 diabetes,and islet β cell dysfunction and insulin resistance are the main mechanisms of type 2 diabetes.Recent studies have revealed that autophagy plays an important role in maintaining the structure and func-tion of islet beta cells and inhibiting insulin resistance and apoptosis induced by oxidative stress.In this review,we discussed the positive and negative effects of autophagy and its dysfunction on type 2 diabetes mellitus,which is the so-called double-edged sword,analysed its possible mechanism,and identifed possible research hot spots. | Ding Yao Yang GangYi Wu QiNan | 2021 | Genes & Diseases2021，8，4： | 1 |
