This paper models extravascular MRI signal decay (R2/R2*) as a function of blood oxygenation, vessel geometry, and magnetic field strength up to 9.4 T using Monte Carlo diffusion simulations. It reports different vessel-size dependencies for Hahn-spin-echo versus gradient-recalled-echo relaxation across field…

This physics study reports ultranarrow optical absorption and two-phonon excitation spectroscopy of Cu2O paraexcitons in a high magnetic field at 1.2 K. A magnetic field enabled observation of an otherwise forbidden paraexciton absorption line and allowed measurement of field-dependent oscillator strength and energy…

This exposure assessment measured 20 kHz magnetic field leakage from induction cooking heaters across four models and compared results with ICNIRP general public limits. The maximum reported magnetic flux density was 16 µT at a specified measurement point using two S-type pans. Field leakage depended on pan size and…
