#### Closed lattice of Toda equations

The method of closed chains of discrete symmetries is used to multiply Toda lattices in one and two spatial dimensions. Using the modified Toda equations m0TCand m1TC as an example, it is shown that the combination of the Darboux and Schlesinger **transformations** leads to closed dressing chains.

#### The application of the method of average sections with coordinate **transformation** in three-dimensional modeling of dragline waste rehandling

... that information and analytical technology for modeling dragline waste rehandling in three-dimensional space through two-dimensional numerical algorithms. Using the methods of analytical geometry and mathematical statistics, a number of problems of **transforming** basic data to net models, creating average sections and local systems of coordinates, modeling routes of excavators in local systems of coor-dinates, and return **transformation** of modeling results to the initial system of coordinates have ...

#### The modern natural-anthropogenic prerequisites for the **transformation** of eolian coastal-marine natural complexes

This article offers the results of an analysis of natural and anthropogenic impacts on eolian coastal marine natural complexes of the Curonian and Vistula spits. The authors identify the contribution of natural and anthropogenic factors to the **transformation** of the spits’ natural complexes.

#### Algebra method of the construction of the Maxwell equations in a 2D inhomogeneous dielectric

We study discrete isospectral symmetries for the linear problem in spatial dimensions two, by developing a Darboux (Moutard) **transformation** formalism for this problem. As an application, we construct some singular and nonsingular integrable potentials (dielectric permitivity) for the Maxwell equations in a 2D inhomogeneous medium.

#### Mathematical Model of Intramolecular Tautomeric **Transformation** and the Processes of a Relaxation of the Proton

A quantum statistical model of intramolecular tautomeric **transformation** is offered, accounts for the vibration of a proton as a result of its interaction with the surrounding medium simulated by the quantized field of radiation. Effective adiabatic potentials of the proton are approximated by the parabolas ...

#### The formation of the political elite in Lithuania at the turn of the 1980s—1990s: the role of “moral politicians”

... disintegration and further development of the country's policy. The role of the political elite, which is understood according to R. Putnam and J. Higley's definition, is considered in the conditions of political instability and uncertainty typical of **transformation** processes. In this context, the role of key actors is interpreted on the basis of the methodological structure of the so-called Stanford model developed by G. Almond and P. Bourdieu's theory of capital. This article reconstructs the course ...

#### Semantic **transformations** in the secondary text (on A. Döblin’s fairy tale “Der Ritter Blaubart”)

The article examines the scope and significance of semantic **transformations** of the secondary text — the fairy tale Der Ritter Blaubart” by Alfred Döblin. The article reveals that the **transformation** of the tale, which emerged in the stream of post-modernism, is a complex formation which reveals both the features ...

#### Psychological health of senile men and women during the COVID-19 pandemic

... anxiety, general neuropsychic tension, level of life satisfaction, general emotional background. The developed program will be in demand for reducing negative manifestations in the mental state of the elderly in the conditions of active modern social **transformations**, since mental reactions to dangerous situations are largely similar and universal.

#### Organized crime in the Soviet Russia: the paradox of institutionalization. Part One.

The aim of the study is to define the role of organized crime in Russia over a major period in the 20th century, and analyze **transformation** that this criminal activity underwent. The article opens with the analysis of the development processes of the organized crime typical for the Soviet society. It is shown that in the Soviet period of history, organized crime, inheriting ...

#### Valuating the appropriation of digital technologies across Russian regions

... from February 2019 to January 2021. The findings suggest that Russian regions may be divided into digitally advanced areas, runner-ups, average performers, and the digital periphery. Recommendations are given on how to increase readiness for digital **transformation** in territories of different types without running the risks of forced digitalisation.

#### Film dialogue as an auto-adaptation of a literary text (on the «Room» shooting script, 2015)

... as a complete and organized formation in the structure of a film work that has clearly defined functions. Contrastive approach allows to consider the adapted film dialogue in comparison with its original literary dialogue and to identify a number of **transformations** that take place in the process of its adaptation for a film. Undertaken linguistic analysis can serve as the basis for further study of the actual language material in the context of film adaptation as a linguistic problem.

#### On the problem of acausal semantic coincidences: the cognitive background of omens

The authors study the issue of acausal semantic coincidences (synchronicity) for the first time as omens of war in the Russian linguocultural tradition. The semiotic structure of omens is shown, and models of **transformations** of situational semantics in their signifier and signified are revealed. In particular, symbolic substitutions are possible in the signifier, and a sequence of metonymic shifts in the causal field of war in the signified. In general, ...
