RCS REDUCTION OF QUASI-YAGI ANTENNA [PDF]
Progress In Electromagnetics Research C, 2014 A novel Quasi-Yagi antenna with low radar cross section (RCS) is proposed in this paper. By using arrow-shaped Koch dipoles as the driver and director and cutting the ground of the antenna, the RCS can be reduced in the operating band of 5 GHz-8 GHz when the incident wave is perpendicular to the antenna plane.

Randomized preclinical study of machine perfusion in vascularized composite allografts
BJS (British Journal of Surgery), EarlyView., 2020 This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.
