For test problems the experimental value of the approximation order of ...
Hybrid attack on Learning with Errors (LWE) with sparse secret
... meet-in-the-middle (MiTM). In this article, we apply hybrid attack to the Learning with Errors Problem (LWE) with sparse secret. The LWE problem is considered to be one of the most important in lattice-based cryptography. Large number of cryprographic schemes ranging from basic signature and encryption schemes to advanced schemes like group signatures and fully homomorphic encryption, base their security on the hardness assumption of LWE. In this paper, we review the hybrid attack and the algorithms ...
Institutional approach to assessing the transition to a circular economy: the case of the Kaliningrad region
... to a circular economy in the Kaliningrad region. Methodologically, the study uses instruments of new institutional economics: by comparing discrete institutional alternatives for municipal solid waste (MSW) management, the authors propose incentive schemes that will likely stimulate the transition to a circular economy in the region. It is shown that, in Russia, the identification of the holder of the property right to waste is complicated. This can be a hindrance to effective MSW management. Moreover,...

A review of the existing generalizations of the Deuring Reduction Theorem
... generalizations of the Deuring Reduction Theorem. Our research proves that the most appropriate theorem for further elaboration is the one that relates the decomposition of pK into prime ideals with the decomposition of A[p] into indecomposable BT1-group schemes up to isomorphism. The article investigates basic problems of the theorem's further generalization and some ways of solving them as well as formulates tasks for further work in this direction.

We also describe the processes of encryption and decryption of messages using this. As a result,...
The Praed model sentences: meaning and speech functions.

Having considered the classical and modern research papers, the author examines the grammatical status of uninflected words, which are the main members of the sentences of the Praed structural scheme. The author considers that such words should be classified as predicative adverbs rather than a special grammatical category. The article proposes a semantic typology of such adverbs functioning in modern colloquial speech. The author concludes ...

This means that the preservation of direction variables is a distinctive feature representing a scheme of thinking and, therefore, a system of philosophy. Schemes of thinking are not determined by synthesis or removal, but rather by preservation. In conclusion, it is possible to state that, in Cohen’s critical idealism, this belongs to the basic ...

This principle of iconography is clearly seen in Russian icon painting....
