Research of dynamics of nonlinear corrosion processes of non-nickel titanium shape memory alloy Ti-20Nb-10Ta is performed. Samples were placed in mediums imitating physiological liquids, with ðÍ from 1.68 to 9.18. 3 types of samples were used: in an initial state, after thermal (annealing) and surface mechanical treatment. After annealing, there is a slight narrowing of the X-ray peaks, which indicates stress relief. New phases are not allocated. The alloy is a substitution solution with a b-Ti lattice. The greatest release of titanium ions was observed in solution with the sourest environment and samples after annealing. Release of niobium and tantalum ions in solution with any acidity was not observed.

This set of notes is intended for a short course aiming to provide an (almost) self-contained and (almost) elementary introduction to the topic of Information Geometry (IG) of the probability simplex. Such a course can be considered an introduction to the original monograph by Amari and Nagaoka [1], and to the recent monographs by Amari [2] and by Ay, Jost, Lê, and Schwachhöfer [3]. The focus is on a non-parametric approach, that is, I consider the geometry of the full probability simplex and compare the IG formalism with what is classically done in Statistical Physics.

Mathematical problem of encoding of the universe quantum state in the cosmological singularity is considered using a free and massless scalar .eld as a prototype of matter. Two di.erent but coherent approaches to this issue are presented. The expression for the scalar particles' spectral energy density, which is initially encoded at the singularity, is deduced. An informational aspect of the problem is discussed.
