Optimized motion‐insensitive PDFF mapping of the liver
Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 249-267, January 2026.Abstract Purpose To implement, optimize, and validate parallel imaging (PI)‐accelerated, 2D, flip angle modulated (FAM) chemical shift‐encoded quantification of liver proton‐density fat fraction (PDFF), with motion insensitivity. Methods The optimization cost function that determines flip angles in FAM was generalized for PI.

Research on Peak‐to‐Average Power Ratio Control Method for Switched Reluctance Pulse Generator
IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.Addressing the different requirements for peak output power when SRPG supplies power to pulse loads and DC loads, the peak‐to‐average power ratio (PAPR) is taken as the generation performance optimisation parameter. By investigating the power characteristics of the SRPG, the influence of control parameters on the PAPR is studied.
