TL;DR: This paper studies the vision-based object detection and target tracking control method for quad-rotor UAV with unknown camera parameter, utilizing the YOLO v4 algorithm to achieve the onboard object detection of UAV and an optimized tracking controller based on LQR method designed with camera parameters being unknown.
Early ligation of the pulmonary vein can reduce the dissemination of shed tumor cells during thoracoscopic lobectomy.
TL;DR: In this article , the authors explored whether the timing of pulmonary vein (PV) ligation determined according to the early and late ligation technique is associated with CTC dissemination.
Pathological complete response to neoadjuvant chemoimmunotherapy correlates with peripheral blood immune cell subsets and metastatic status of mediastinal lymph nodes (N2 lymph nodes) in non-small cell lung cancer.
Tian-cheng Ma,Tao Wen,Xunquan Cheng,Yuxuan Wang,Pan-dan Wei,Bin Yang,Ling Yi,Xiaojue Wang,Zhuohong Yan,Jinghui Wang,Zhihong Liu +10 more
TL;DR: The peripheral blood immune cell subsets and lymph node status were closely related to pathological response in patients with neoadjuvant chemo-immunotherapy, and no significant correlation was found between pathologic response and PD-L1 expression.
