| 1 | End-to-End Joint Multi-Object Detection and Tracking for Intelligent Transportation Systems显示文摘Environment perception is one of the most critical technology of intelligent transportation systems(ITS).Motion interaction between multiple vehicles in ITS makes it important to perform multi-object tracking(MOT).However,most existing MOT algorithms follow the tracking-by-detection framework,which separates detection and tracking into two independent segments and limit the global efciency.Recently,a few algorithms have combined feature extraction into one network;however,the tracking portion continues to rely on data association,and requires com‑plex post-processing for life cycle management.Those methods do not combine detection and tracking efciently.This paper presents a novel network to realize joint multi-object detection and tracking in an end-to-end manner for ITS,named as global correlation network(GCNet).Unlike most object detection methods,GCNet introduces a global correlation layer for regression of absolute size and coordinates of bounding boxes,instead of ofsetting predictions.The pipeline of detection and tracking in GCNet is conceptually simple,and does not require compli‑cated tracking strategies such as non-maximum suppression and data association.GCNet was evaluated on a multivehicle tracking dataset,UA-DETRAC,demonstrating promising performance compared to state-of-the-art detectors and trackers. | Qing Xu Xuewu Lin Mengchi Cai Yu‑ang Guo Chuang Zhang Kai Li Keqiang Li Jianqiang Wang Dongpu Cao | 2023 | Chinese Journal of Mechanical Engineering2023，36，5： | 0 |
| 2 | Highly efficient artificial blood coagulation shortcut confined on Ca-zeolite surface显示文摘It is challenging to develop an in w'fro catalytic system to conduct natural surface-confined enzymatic reactions in a stable,efficient,and spatially defined manner.Here,we report that an artificial catalyst,which composes of trypsin and a calcium ion exchanged zeolite Y(trypsin/CaY),is capable of conducting surface-confined thrombin generation,and then constructs an artificial shortcut for classic,natural and complex blood coagulation cascade.The Ca2+within the microporous cages play a key role in trypsin/CaY hybrid through tuning the bio-inorganic interaction and spatial orientation of the protease,which allows trypsin/CaY to display greatly enhanced catalytic performance in coagulation process.The in vivo efficiency of the artificial coagulation shortcut is further confirmed in massive bleeding and hemophilia animal models.Rapid hemostasis is achieved by trypsin/CaY hybrid in a hemophilia A mice tail bleeding model,where natural clotting system fails in response to bleeding event due to factor VIII deficiency.In a rabbit lethal femoral artery injury model,the blood loss of the artificial catalyst is decreased by 4-7 fold when compared to state-of-art clay-or zeolite-based topical agents. | Lisha Yu Bin Yu Hao Chen Xiaoqiang Shang Min He Mengchi Lin Dan Li Wenzhao Zhang Zhengzhong Kang Jiachen Li Fangjun Wang Liping Xiao Qi Wang Jie Fan | 2021 | Nano Research2021，14，9： | 0 |
