Design and experiment of a bionic flapping wing mechanism with flapping–twist–swing motion based on a single rotation

In the present study, a bionic flapping mechanism of a spatial six-bar configuration was designed to transform a single rotation of a motor into a three degrees of freedom “flapping–twist–swing” cooperative motion of a flapping wing.The kinematics model of the flapping mechanism movement was constructed.The flapping trajectory of the wing b

Pulmonary Metastasis from Pseudomyxoma Peritonei

Pseudomyxoma peritonei (PMP) is a rare clinical condition, where copious mucinous ascites accumulate in the peritoneal cavity due to dissemination of mucin-producing tumor.Because of this disseminating, yet nonmetastasizing, behavior, PMP attracts much interest from surgical oncologists in that aggressive 9x11 pergola locoregional therapy can give
