«А благородство моё во мне унывает…»: Какой из четырех Евгениев настоящий?

The article is devoted to the analysis of four characters named Eugene (heroes of A. Kantemir’ satire, A.E. Izmailov’s novel, A. Pushkin’s Eugene Onegin and The Bronze Horseman), represents the initial stage in the evolution of the semantic halo of this name in Russian literature, through an onomastic prism. The study is based on a matrix that takes into account the interaction of components that make up the semantic core of the concept of "nobility": nobility of the family, adherence to external decorum, high moral qualities. The main point was to check in Russian literature for "true Eugene", possessing all the signs of nobility, genetic, external, internal. The answer turned out to be negative: the semantics of the loss of various components turns out to be a constitutional feature of the semantic halo of the name. Russian literature at the initial stage of the development of "Eugene's plot" was more likely to move away from the semantics of the name, fixing the absence of nobility in the "noble", differently approaching the description of this phenomenon. Four heroes were involved in a united plot of the evolution of the semantic halo of the name - processing from satire to tragedy.

Thermodynamic analysis of interaction of components in the SIO2-C system: improvement of technical silicon production technological process

In order to identify ways to improve the technological process of smelting metallic (crystalline) silicon of technical purity, a thermodynamic analysis of the interaction of components in the SiO2-C system is carried out that reveals the main factor in obtaining high-quality technical silicon is the elimination of superposition of the silicon carbonization process that is possible by carrying out a two-stage carbothermal reduction reaction, in that firstly the incomplete reduction of silica (SiO2) by solid carbon (C) is provided, accompanied by the release of new reacting gas components - SiO and CO, the subsequent interaction of which leads to the formation of the target product - technical silicon that is suitable for the production of modern solar energy converters. It is determined that main condition for highly efficient reduction reactions is the fine fractionness (<1 mm) of the used quartzite ore with keeping of a rational temperature range for its carbothermal reduction (1688-2000 K). It has been shown experimentally that the optimal technical solution for the implementation of this reduction process is to performt melting in a special plasma-chemical furnace-reactor with one liquid-metal subconducting electrode, with a reverse vertical feed of the reaction gases released at the first stage. The degree of extraction of silicon was on average 95%, and the degree of its purity was 97.2%.

Interaction of Components in the Lu-Ag-Si System at 500 ºC

Isothermal section of the Lu-Ag-Si system at 500ºC was studied by means of X-ray powder diffraction, microstructure and EDX-analyses in the whole concentration range. The existence of earlier reported binary compounds LuAg4, LuAg2, LuAg and LuSi2, LuSi, Lu5Si3, Lu5Si4 was confirmed. New binary compound Lu3Si5 (own str. type) was found. Almost none of the binary silicides dissolve more than 5 at.% of third component. The exception is the existence of the substitution type solid solutions based on LuAg2 (MoSi2-type structure), which dissolves up to 20 at.% Si, as well as on Lu5Si3 (Mn5Si3-type structure), which dissolves up to 15 at.% Ag. The crystal structure of the LuSi compound was redetermined by X-ray single crystal diffraction (TlI-type, space group Cmcm, a = 4.1493(3), b = 10.2641(7), c = 3.7518(2) Å, R = 0.0173, wR = 0.0415 for 173 independent reflections). No ternary compound is observed in the Lu-Ag-Si system.

Reassessing Personality and Narratives in the Brain and Behavioral Health Sciences

Narratives play an important role in the conceptualizations and classifications of mental disorders and cognitive dysfunctions. They recur in psychiatry, psychology, cognitive sciences, impairments' therapeutics, etc. Despite their relevance, first-person reporting and specialists' recounting of clinical cases have been understated in the literature. This is intriguing since narratives can potentially influence diagnostic statements, procedures, and prescriptions of rehabilitation treatments. They can also account for the extent to which certain disorders are normalized or pathologized within specific cultural contexts. Nonetheless, a narrative/story/description cannot be substituted for the contributions of the brain and behavioral health sciences. In Section I, we summarize three reasons that could explain the deflationary view of narratives in the clinical and neuroscientific literature: a) The brain and behavioral health sciences’ aspiration to emulate successful disciplines centered on pathogen-causal models; b) The bioinspired explanatory patterns; and c) The brain and behavioral health sciences’ neglect of the big picture, i.e., the interaction of components when a cognitive/psychiatric/psychological problem presents. A concomitant core problem is presented in Section II: Psychiatry's out-of-date conception of personality assumes that personality traits are fixed features of a subject’s identity and that identity is a static closed system. In Section III, we challenge this view and urge brain and behavioral health sciences professionals to update their notion of personality and narrative. We conclude by offering some criteria that distinguish genuine narratives from story-like accounts (i.e., genuine narratives must be consistent, explanatory, coherent, and constant).

Diagnosis of Deep Discrete-Event Systems

An abduction-based diagnosis technique for a class of discrete-event systems (DESs), called deep DESs (DDESs), is presented. A DDES has a tree structure, where each node is a network of communicating automata, called an active unit (AU). The interaction of components within an AU gives rise to emergent events. An emergent event occurs when specific components collectively perform a sequence of transitions matching a given regular language. Any event emerging in an AU triggers the transition of a component in its parent AU. We say that the DDES has a deep behavior, in the sense that the behavior of an AU is governed not only by the events exchanged by the components within the AU but also by the events emerging from child AUs. Deep behavior characterizes not only living beings, including humans, but also artifacts, such as robots that operate in contexts at varying abstraction levels. Surprisingly, experimental results indicate that the hierarchical complexity of the system translates into a decreased computational complexity of the diagnosis task. Hence, the diagnosis technique is shown to be (formally) correct as well as (empirically) efficient.

Technology for Producing Composite Materials Based on Multi-component Man-generic Raw Materials

The state and prospects of development of production of composites based on various types of multicomponent raw materials (silicon oxide, slag, etc.) and their components are considered. Modern achievements in the field of condensed matter physics of composite materials with mineral matrices and various dimensional levels of fillers are considered. The approaches of leading scientific schools to the creation of composites are analyzed; it is revealed that many issues of obtaining multicomponent composite materials remain open. It is concluded that the optimization of the process of obtaining composites based on multicomponent raw materials should be carried out by changing the target functions and parameters that take into account all types of interaction of components. A method for selecting mineral matrices for the production of composite materials has been developed, the essence of which is to compare the component compositions of raw materials and composite materials, and the search for matrices is performed by the maximum optimal value of intermolecular distances in multicomponent raw materials and composite materials.
