| 1 | Histopathological changes of free buccal mucosa and colonic mucosa grafts after translation to dog bladder显示文摘Over the past years, more cases using buccal mucosa for urethral reconstruction have been reported. 1-4 The excellent early results with this tissue led some authors to extend their indications for its use. However, patients with complex, long-segment urethral strictures and significant scar tissue formation after the failure of previous urethroplasty, still present an operative challenge. The buccal mucosa may not be useful for the treatment of the complicated lengthy urethral strictures because of limited material. | XUYue-min SAYing-long QIAOYong ZHANGHui-zhen ZHANGXin-ru ZHANGJiong CHENZhong XIEHong SIJie-min LITai | 2005 | Chinese Medical Journal2005，，4： | 12 |
| 2 | Associative affinity network learning for multi-ob ject tracking显示文摘We propose a joint feature and metric learning deep neural network architecture,called the associative affinity network(AAN),as an affinity model for multi-object tracking(MOT)in videos.The AAN learns the associative affinity between tracks and detections across frames in an end-to-end manner.Considering flawed detections,the AAN jointly learns bounding box regression,classification,and affinity regression via the proposed multi-task loss.Contrary to networks that are trained with ranking loss,we directly train a binary classifier to learn the associative affinity of each track-detection pair and use a matching cardinality loss to capture information among candidate pairs.The AAN learns a discriminative affinity model for data association to tackle MOT,and can also perform single-object tracking.Based on the AAN,we propose a simple multi-object tracker that achieves competitive performance on the public MOT16 and MOT17 test datasets. | Liang MA Qiaoyong ZHONG Yingying ZHANG Di XIE Shiliang PU | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，9： | 0 |
