Symmetric and antisymmetric forms of the Pauli master equation (for interaction of matter and antimatter quantum states)

, 2016
When applied to matter and antimatter states, the Pauli master equation (PME) may have two forms: time-symmetric, which is conventional, and time-antisymmetric, which is suggested in the present work.

Integrated Assessment of Lipid Oxidation and Off‐Flavor Formation in Plant Protein Powders

Journal of the American Oil Chemists' Society, EarlyView.
Impact of residual lipids on oxylipin and off‐flavor formation in commercial plant proteins: A detailed analysis of precursor‐product relationships by GC‐FID, LC‐MS/MS, and GC‐MS. ABSTRACT The widespread adoption of plant proteins is hindered by their inherent off‐flavors, often linked to lipid oxidation products.
