We propose a new parametrization of dark energy motivated by thermodynamics. To this aim, we consider Padé polynomials to reconstruct the form deceleration parameter adequate describe different epochs cosmic history and divergence-free in far future. The proposed scenario also fulfils demand structure formation contains ?CDM model as limiting case. Thus, numerical analysis at both background pe...

We introduce the simple parametrization for the space of codons (triples of nucleotides) by 8 × 8 table. This table (which we call the dyadic plane) possesses the natural 2–adic ultrametric. We show that after this parametrization the genetic code will be a locally constant map of the simple form. The local constancy of this map will describe degeneracy of the genetic code. The map of the genet...

In this paper, we consider the identification problem arising in the ageperiod-cohort models, as well as in the extended chain ladder model. We propose a canonical parametrization based on the accelerations of the trends in the three factors. This parametrization is exactly identified. It eases interpretation, estimation and forecasting. The canonical parametrization is shown to apply for a cla...
