Dynamic Margin of Stability During Walking Differs Between End-Stage Hip, Knee, and Ankle Arthritis. [PDF]
J Orthop ResABSTRACT End‐stage arthritis of the hip, knee, or ankle leads to differential gait adaptations, but the differences in gait stability remain poorly understood. This study examined whether dynamic gait stability differed between patients with end‐stage hip arthritis (HA), knee arthritis (KA) and ankle arthritis (AA), and matched healthy controls (HC ...

Analysis of water-equivalent materials used during irradiation in the clinic with XCOM and BEAMnrc
Journal of Radiation Research and Applied Sciences, 2019 The devices used in the departments of Radiology, Nuclear Medicine, and Radiation Oncology should check for precise dose at some periods. The purpose of study is to compare the materials used for dosimetric control using Monte Carlo (MC) simulation. For MC simulation, BEAMnrc and DOSXYZnrc were used.
