Type 2 diabetes mellitus (T2DM) is a multifactorial metabolic and widespread disease. In patients' pancreas, islet amyloid polypeptide (IAPP) is found as aggregates. [...]

We present first-principles numerical calculations of the depolarization rate of spin-polarizeddeuterium and tritium nuclei in realistic tokamak plasmas, driven by resonant interactions withplasma waves. Backed up by first-of-a-kind linear and nonlinear simulations, we find that alphaparticle-driven Alfvénic modes cause only negligible depolarization, which is contrary toexpectations in prior literature.
