On the Method of Harmonic Balance for Lumped‐Element Transformer Models

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

Quantitative Investigation of Nitrosamine Drug Substance‐Related Impurities (NDSRIs) Under Artificial Gastric Conditions by Liquid Chromatography–Tandem Mass Spectrometry and Structure–Activity Relationship Analysis

open access: yesDrug Testing and Analysis, EarlyView.
The study provides information about the impact of physiological gastric conditions on the unbeneficial occurrence of nitrosamine drug substance–related impurities (NDSRIs). Both main factors for nitrosation in the form of acidic conditions and the presence of nitrite were adequately chosen for triggering the conversion of drug compounds into NDSRIs ...
