Yada et al. (2022) | 1.282 ± 0.231 | 204 | Spheroid model of Eq. (1) based on a correction factor of 0.928 derived from Bagheri et al. (2015) |
Nakamura et al. (2022a) | 1.528 ± 0.242 | 16 | 3D model obtained by optical profilometry |
Nakamura et al. (2022b) | 1.79 ± 0.08 | 16 | 3D model obtained by X-ray computed tomography (XCT) |
This work | 1.79 ± 0.31 | 637 | Spheroid model of Eq. (1) based on a correction factor of 0.860 ± 0.044, derived from Nakamura et al. (2022b) using XCT |
