What is the origin of the high brain complexity that explains the deep intricacies and refined levels of cognitive integration in the brain to form, for example, memory and consciousness?

We consider a periodic parabolic singularly perturbed boundary value problem for the Tikhonov system: a singularly perturbed system with fast and slow equations. An asymptotic approximation of the solution to the problem is constructed, conditions for the existence of a solution and its asymptotic stability according to Lyapunov are obtained for these solutions as solutions to the corresponding initial-boundary value problems for this system, both in the case of various types of quasi-monotonicity and in the case of its violation.

In the modern rethinking of neo-Kantian history and ideas, the Russian version of neo-Kantianism has a special, but still unclearly defined place and not realized in all its significance. Previous, traditional techniques and classifications of Russian neo-Kantianism can no longer be adequately used when analyzing this phenomenon on Russian soil: the data accumulated in the course of historical and philosophical research require special study and the creation of new explanatory models. This unique phenomenon - Russian neo-Kantianism, once nurtured and cherished by neo-Kantian scholars - will, over time, make it possible to rethink the ideological role in the modern world of both neo-Kantianism in general and, first of all, its Marburg school as an institutionally and theoretically more “strict” branch neo-Kantian movement.

This research compares two middle years of a four-year undergraduate degree over two consecutive years, focusing on English as a Foreign Language. Year 1 saw 73% of online teaching and learning, while Year 2 saw 25%. The authors compared the relative effects of more vs. less online on examination results. Participants were 105 Methodologists (future teachers) and 272 Translators (n=377), predominantly female (83%).

A finite additive measure will be constructed on a separable Hilbert space, invariant with respect to a shift to any vector. Invariance will allow us to construct smoothed functions differentiable along any coordinate direction, embedded in quadratically integrable functions, as well as tightly defined Laplace operator and Hamiltonian of an infinite-dimensional quantum oscillator. By analogy with the finite-dimensional case (Yu.N.Orlov, V.Zh.Sakbaev, D.V.Zavadsky), an approximation of the evolution of a quantum oscillator will be proved by averaging random shifts in the coordinate and pulse representations.

The uncontrollable proliferation of human papillomavirus (HPV) can cause severe cervical cancer. The objective of this work is to study the optimal control of HPV viral replication and its consequence in reducing cervical cancer cells. For this purpose, the dynamics involving healthy cells, HPV and cervical cancer cells will be modelled by a system of five differential equations.

This presentation is dedicated to the modification of the Biginelli reaction for the synthesis of trisubstituted imidazoles from readily available acyclic N, N-bis-nucleophiles, 2-oxoaldehydes and 1,3-dicarbonyl compounds. Most of the synthesized products were successfully used in the subsequent photocyclization reaction to form structurally interesting polycyclic molecules. The replacement of N, N-bis-nucleophiles to ketenaminals allowed to carry out a similar process in a chemoselective manner to obtain a diverse library of fused polyheterocycles including pyrrolo[2,1-b]thiazoles, pyrrolo[1,2-a]imidazoles and imidazo[1,2-a] quinolines.

For the case of scalar conservation laws with strictly convex flux (like the Hopf equation), an almost optimal result on subdomain control is established.

Protecting modern network infrastructure against cyberattacks is becoming increasingly difficult due to its complex and ever-changing nature. Developing a comprehensive approach known as defensible network architecture is essential to address this challenge. This approach is based on several fundamental principles, including defense in depth, zero trust, segmentation, micro-segmentation, and automation.

The talk is devoted to the theory of matrix quasi-elliptic operators. For some classes of quasi-elliptic operators, isomorphism theorems in special weighted Sobolev spaces are formulated. The results obtained are applied to the study of solvability of equations and systems of Sobolev type.

Scientific purpose: to discuss and compare the approaches of Martin Heidegger and Jose Ortega-y-Gasset towards consciousness and being.

Acyl(imidoyl)ketenes are highly reactive heterocumulenes that enable diversity-oriented synthesis of various drug-like heterocycles. Such ketenes, bearing heterocyclic substituents, afford angularly fused pyridin-2(1H)-ones in their [4+2]-cyclodimerization reactions. We have utilized this property for the development of a new synthetic approach to pharmaceutically interesting pyrido[2,1-b][1,3]benzothiazol-1-ones via the [4+2]-cyclodimerization of acyl(1,3-benzothiazol-2-yl)ketenes generated in situ. The thermal behaviors of 3-aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones and 3-benzoylpyrrolo[2,1-b][1,3]benzothiazole-1,2-dione (two new types of [e]-fused 1H-pyrrole-2,3-diones) have been studied by thermal analysis and HPLC to elucidate their capability to be a source of acyl(1,3-benzothiazol-2-yl)ketenes. As a result, we have found that only 3-aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones are suitable for this. The experimental results are supplemented with computational DFT studies of the possible reaction mechanisms that demonstrate that thermolysis of 3-aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones proceeds through an unprecedented cascade of two thermal decarbonylations.

The isocyanide is an interesting and unique functional group in organic chemistry. The carbon atom in isocyanide can act as a nucleophile, as an electrophile, as a carbine involved in formal [1 + 4] cycloaddition, and as a radical acceptor to form imidoyl radical reaction intermediates. Its nature of the isocyanide makes it capable reacting with different strategies with various reactants under reaction conditions. As a result, the reaction of isocyanide were usually carried out via unpredictable way and obtained unexpected products. In this presentation, numerous unexpected isocyanide-based multicomponent reactions from our research group will be presented.

Recently, the preparation of neoteric functional materials with multicomponent reactions strategy has interestingly enhanced the union of materials chemistry.
