Background: Exosomes are cell-derived vesicles and bear a specific set of nucleic acids including DNA (exoDNA).Thus, this study is to explore whether exoDNA in malignant pleural effusions (MPEs) could be a novel DNA source for mutation detection of epidermal growth factor receptor (EGFR).Methods: In this study, 52 lung adenocarcinoma patients were
The human brain is composed of two broadly symmetric cerebral hemispheres, with an abundance of reciprocal anatomical connections between homotopic locations.However, to date, studies of hemispheric symmetries have not identified correspondency precisely due to variable cortical folding patterns.Here Perfume we present a method to establish accurat
In high dynamic scenes, fringe projection profilometry (FPP) may encounter fringe saturation, and the phase calculated will also be affected to produce errors.This paper proposes a saturated fringe restoration method to solve this problem, taking the four-step phase shift as Pipe Cutting Machine an example.Firstly, according to the saturation of th
