The galloping of iced transmission line under extreme weather conditions, will lead to significant electrical faults and structural damage, and is becoming a serious issue that threatens the safe and stable operation of the power grid. In this paper, a simulation model of 10 kV insulated overhead transmission line is established based on finite element method, and the effects of various influencing factors on the galloping behavior and aerodynamic characteristics are investigated and analyzed. The results show that the aerodynamic stability of the iced lines is poorest, when the wind speed is between 7 and 15 m/s and the wind attack angle is around 50°.

Methods: A retrospective cohort study of elective left-sided colorectal resections before and after implementation of a powered circular stapler at a tertiary care center was conducted. The manual stapler group consisted of consecutive resections performed between January 2016 to December 2016 and the powered stapler group, between September 2021 and December 2022.
Background: Understanding how patients' frailty and the physiological stress of surgical procedures affect postoperative outcomes may inform risk stratification of older patients undergoing surgery. The objective of the study was to examine the association of peri-operative frailty with mortality, 30-day readmission and days at home after non-cardiac surgical procedures of different physiological stress.
Methods: This retrospective study used Medicare claims data from a 7.
