The Kimura 3-parameter model is one of the most fundamental phylogenetic models in algebraic statistics. We prove that all varieties associated to this are projectively normal, confirming a conjecture Michałek.

The paper introduces a straightforward procedure for estimating the electrical parameters of simple, but reasonably accurate, two-branches model supercapacitor (SC). equivalent circuit includes voltage and frequency dependence on SC’s capacitance, neglecting self-discharge phenomenon, so it is mainly devoted to short mid-term simulations suitable most industrial applications. estimation starts ...
