L.S. Vygotsky: Reading Anew. Part 1.
No full textThe article dwells on the earlier period of Vygotsky’s works before the time when the principles of the Cultural Historic Theory were formulated. His report on the 2nd Psycho-Neurologic Congress in 1924 as well as some adjacent works including “The historical sense of psychological crisis” are considered by the author as key moments. If to compare Vygotsky’s approach with I.P. Pavlov’s theory of conditioned reflex, V.M. Bechterev’s reflexology and K.N. Kornilov’s reactology,from one side, and psychology, from the other, it reveals Vygotsky’s determination to restructure psychology on the objective basis. In his opinion this implies the turn of psychology to higher forms of human’s behavior, actually, to human activity. In these methodological changes of Vygotsky’s views one can trace certain relations of Vygotsky’s early works with P.Ya. Galperin’s theoretical survey on subject and method of psychology.</p
On the Psychological Mechanism of Ontogenetic Development in the Context of Developmental and Educational Psychology
No full textAbstractThe article offers the author's view of the psychological mechanism for the development of a child. It is regarded as the process of ripening and resolving of fundamental contradictions between the child's system of relations and modes of activity acquired by him. Underlined by the author is the objective nature of ontogenetic development as well as the role of child's motivation as a driver of necessary transformations of the child's activity leading to his psychological growth. The similarities and differences between the author's approach and that of D. B. Elkonin are precisely traced. The author’ arguments are supported by a lot of evidence from the theory and practice of developmental and educational psychology with special focus on the role of social institutions
STATISTICS OF NODES AND RANDOM WALKS WITH TOPOLOGICAL LIMITATIONS
No full textThe probabilistic-topological properties of the random nodes have been studied. The basic attention has been paid to the problems on the determination of the node entropy and their connections with problems of the non-ordered system theory. The properties of the limit distributions for random walks on some non-commutative groups have been investigated. The physical properties of the polymer systems with topological limitations have been considered.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
SERGEY NECHAEV AND DOSTOEVSKY’S DEVILS: THE LITERARY ANSWER TO TERRORISM IN NINETEENTH-CENTURY RUSSIA
No full textNon-autoregressive real-time Accent Conversion model with voice cloning
No full textCurrently, the development of Foreign Accent Conversion (FAC) models utilizes
deep neural network architectures, as well as ensembles of neural networks for
speech recognition and speech generation. The use of these models is limited by
architectural features, which does not allow flexible changes in the timbre of
the generated speech and requires the accumulation of context, leading to
increased delays in generation and makes these systems unsuitable for use in
real-time multi-user communication scenarios. We have developed the
non-autoregressive model for real-time accent conversion with voice cloning.
The model generates native-sounding L1 speech with minimal latency based on
input L2 accented speech. The model consists of interconnected modules for
extracting accent, gender, and speaker embeddings, converting speech,
generating spectrograms, and decoding the resulting spectrogram into an audio
signal. The model has the ability to save, clone and change the timbre, gender
and accent of the speaker's voice in real time. The results of the objective
assessment show that the model improves speech quality, leading to enhanced
recognition performance in existing ASR systems. The results of subjective
tests show that the proposed accent and gender encoder improves the generation
quality. The developed model demonstrates high-quality low-latency accent
conversion, voice cloning, and speech enhancement capabilities, making it
suitable for real-time multi-user communication scenarios.Comment: 8 pages, 6 figures, 3 table
Role of the A.I. Urusov in the development of Russian jurisprudence
No full textRussian jurisprudence has a long history of development, in which individuals played an important role: lawyers, human rights defenders, counsels. One of the prominent Russian human rights defenders was Alexander Ivanovich Urusov. The authors study his personality and professional activities in trials as a sworn attorney. His difficult career path and the participation in the "Nechaev" case were considered. © 2020 Rossiiskaya Akademiya Nauk, Institut Istorii (Russian Academy of Sciences, Institute of General Hist.

No full textNonlinear electrodynamics at cylindrical “cumulation” fronts
No full textConverging cylindrical electromagnetic fields in vacuum have been shown (Zababakhin and Nechaev Sov Phys JETP 6:345, 1958) to exhibit amplitude “cumulation”. It was found that the amplitude of self-similar waves increases without bounds at finite distances from the axis on the front of the fields reflected from the cylindrical axis. In the present paper, we propose to exploit this cylindrical cumulation process as a possible new path towards the generation of ultra-strong electromagnetic fields where nonlinear quantum electrodynamics (QED) effects come into play. We show that these effects, as described in the long wave-length limit within the framework of the Euler Heisenberg Lagrangian, induce a radius-dependent reduction of the propagation speed of the cumulation front. Furthermore, we compute the e+−e− pair production rate at the cumulation front and show that the total number of pairs that are generated scales as the sixth power of the field amplitude.journal articl
