This engineering simulation study models colloidal particle transport and deposition in a membrane filtration channel at a particle volume fraction of 10%. The model couples a dynamically updating crossflow velocity field with particle-particle and particle-membrane interaction potentials (electrostatic double layer…

This study compared two non-invasive acupoint stimulation methods—TEAS and PEMF—as alternatives to manual acupuncture for recovery from exercise-induced muscle fatigue. Using 2 Hz stimulation (PEMF magnetic flux 30.92 mT), the authors report faster recovery of EMG median frequency and improved peak torque recovery in…

This animal PET study examined whether a weak 60-Hz magnetic field alters brain glucose utilization in rats. The abstract reports increased FDG uptake in hindbrain voxels when a 2.5-G field was oriented orthogonally to the sagittal plane, but not when field direction varied randomly. Distinct activation effects were…

This methods paper addresses how B0 (main field) and B1 (transmit field) inhomogeneities can bias SPGR and bSSFP steady-state MRI signals used for multicomponent T1/T2 relaxometry and myelin water analysis. It describes using DESPOT1-HIFI to calibrate flip angles and adding a B0-related parameter with multiple…

This paper models biological proton pumping in cytochrome c oxidase under an applied oscillating electric field. The authors report that proton pumping efficiency and steady-state electronic currents vary significantly with the field’s frequency and amplitude. A spectral analysis is described as supporting dominant…
