Abstract: A moving object tracking approach for a quadrupedal robot based on a Siamese network comprises an RNN-based object detector for locating moving objects. The position information of moving objects is sent into a ResNet-based feature extractor. For regressing bounding boxes of a target object, a Siamese adaptive network is employed. Experimental results on several public benchmarks show that this approach achieves excellent VOT performances, e.g., it obtains EAO score by 0.452 points, Accuracy score by 0.592 points, and Robustness score by 0.155 points on public benchmark VOT2018. it is successfully used on a quadrupedal robot, which can accurately track a specific moving object in real-world complicated scenes.

Abstract: Disclosed is a stent with a drug coating for preventing and treating restenosis, comprising a stent and a drug coating covering the surface of the stent. The active ingredients in the drug coating are guaiane sesquiterpene compounds P1, P2 and P3. P1 is Zedoalactone B, P2 is a stereoisomer of P1, and P3 is Zedoarondiol. Compared with an existing sirolimus eluting stent, the present drug eluting stent can inhibit the intimal hyperplasia and the inflammatory reactions of vascular walls, and promote the endothelialization of blood vessels after the stent is implanted, and thus can prevent the long-term thrombotic complications; and has the advantages of small dosage, low cost, and no toxic side effect.
