Ryan Tapping – ProQuest LLC, 2021
In this dissertation I will present my work in both the fields of spintronics and physics education research. In the first section, I present a method to account for spin pumping in spin torque ferromagnetic resonance (ST-FMR) measurements. A spin current can be generated via the spin Hall effect (SHE), which is typically transverse to the charge…

Sun, Bo; Liu, Yu; Li, Jing Xian; Li, Haipeng; Chen, Peijie – Research Quarterly for Exercise and Sport, 2013
Purpose: This study set out to examine the relationship between step frequency and velocity to develop a step frequency-based equation to predict Chinese youth's energy expenditure (EE) during walking and running. Method: A total of 173 boys and girls aged 11 to 18 years old participated in this study. The participants walked and ran on a…
