Imbalanced turbulence throttles its cascade via the helicity barrier, yielding flat spectra (η<2) that invert minor-ion heating to Q_i ∝ Q_p A_i (A_i/Z_i)^{η-2}, with simulations across β_p0 confirming the (A_i/Z_i)^a trend and strong perpendicular heating at low β.
Radiative cooling in MADs above a transition accretion rate creates thinner denser filaments with increased efficiency, rendering conventional scale height measures misleading and motivating a new definition based on the polar position of the density maximum.
