P. 113–116.
Ulyanov S., Gourary M. M., Rusakov S. G., Zharov M. M., Rassadin A. E.
The paper presents SPICE models of nonlinear capacitors for analysis of ferroelectric circuits. The capacitors can be defined by either charge-voltage or voltage-charge closed form expressions. Additionally the model for series connection of any number of nonlinear capacitors is proposed. The model takes into account trapped charges of internal connections. Numerical experiments for ferroelectric circuits confirmed the correctness of the proposed approach.

Gemcitabine monophosphate (dFdCMP), one of the intracellular forms of phosphorylated gemcitabine, determines its antitumor activity. A pharmaco-molecular model for determining relative gemcitabine monophosphate level based on the assessment of the activity of ENT1 and ENT2 channels as well as dCK and CDA enzymes in tumor tissue was developed. Relative gemcitabine monophosphate level is a more ...
