Microvascular anatomy of the lateral spinal artery: Origins, collateral channels, and other anatomical variations
Authors: Park Wonhyoung , Xu Yuan , Abramov Irakliy , Preul Mark C.
Published: February 2025

Background:

The lateral spinal artery (LSA) corresponds to the posterolateral arterial axis of the craniocervical junction. Although implicated in various pathologies and injury risks during treatments, the existence and anatomical characteristics of the LSA are debated. We aim to demonstrate the characteristics of the LSA, including its origins, collateral channels, and anatomical variations.

Methods:

Neurosurgeons performed far-lateral craniotomies and cervical laminectomies on 18 cadaver heads (36 sides). Neurovascular structures associated with the LSA were examined in epidural, subdural, and subarachnoid spaces.

Results:

The main origins of the LSA were the V3 segment of the vertebral artery (VA) (n = 18), the V4 segment of the VA (n = 12), and the posterior inferior cerebellar artery (PICA) (n = 6). The PICA originated from V3 in 6 cases; in 5, the main LSA origin was the intradural PICA. In the 30 cases where the PICA originated from V4, only one main LSA originated from the PICA. In addition to the main origin, we identified supplementary origins, averaging 1.7 per case. In 4 cases, the LSA and posterior meningeal artery (PMA) shared an origin at V3. Twenty-seven cases had anastomosis between the LSA and PICA on the pial surface. Collateral channels at the C2 level through posterior radicular arteries were observed in 13 cases.

Conclusion:

The main origins of the LSA are around the dural ring of the VA and are associated with the PICA’s origin. Other potential channels supplying the LSA were also identified. The LSA and PMA may share an origin from the VA.

В статье рассматривается проблема применения механизма риск-ориентированного управления транспортными процессами на железнодорожном транспорте для выявления и предотвращения угроз транспортной безопасности террористического характера. На основе рассмотрения методов оценки вероятности реализации ситуации рисков предложено использование метода построения матрицы рисков, позволяющего осуществлять идентификацию объектов транспортной сферы, являющихся потенциальными источниками террористических рисков. В результате анализа возможности применения данного метода с целью минимизации транспортных рисков предложен механизм управления нетипичными рисками.

The article deals with the problem of applying the mechanism of risk-based management of transport processes in railway transport to identify and prevent threats to transport security of a terrorist nature. Based on the consideration of methods for assessing the likelihood of a risk situation, it is proposed to use a method for constructing a risk matrix that allows the identification of transport facilities that are potential sources of terrorist risks. As a result of the analysis of the possibility of using this method in order to minimize transport risks, a mechanism for managing atypical risks is proposed.

Introduction. Models of nonlinear systems with a chaotic dynamics describe the electronic circuits of signal generators with a complex structure. Dynamic systems such as Chua, DmitrievKislov, Van der Pol, Duffing and AnischenkoAstakhov have been thoroughly studied by scientists. In the paper, it is proposed to use methods of nonharmonic spectral analysis of multiscroll systems based on their decomposition over monotonic intervals in the basis of nonharmonic fractionalpower functions of time. The aim of the research. The aim of the research is to carry out diagnostics of nonlinear multimode multiscroll (multilobe) systems with regular and chaotic dynamics by means of the generalized method of nonharmonic spectral analysis. Solution methods. A generalized model of signals of nonlinear multiscroll systems with chaotic dynamics is represented as a sequence of consecutive pulses. Nonharmonic spectral analysis of the signals of nonlinear radioelectronic systems was carried out by decomposing the signals, presented in the form of pulsed random processes, according to the basis of fraction power functions of time that is adequate for systems with chaotic dynamics. Math modeling. The spectra, presented in the paper, can be considered as distributed and localized. These spectra exhibit fuzzy spectral lines, in contrast to localized spectra. Peak amplitude values of signals are relatively rare. Analysis of simulation results. Analysis of the multiscroll system signals with the use of the proposed approach showed that their fraction power spectra are fairly well localized by decomposition parameters, that indicates the adequacy of the applied basis to this system. Conclusions. Nonharmonic spectral analysis based on representations of nonlinear systems signals in the form of pulsed random processes with fraction power approximation of the pulses envelope can be an additionally applied to support harmonic spectral analysis. Paper presents the relation of local formations in the obtained fraction power spectra of nonlinear dynamic systems of the multiscroll type with the values of the system parameters and the type of regular or chaotic mode that dominates in the system. Fraction power spectra of multiscroll systems with dynamic chaos are classified as distributed and localized. The relation of the parameters of fraction power expansions of signals with the dynamics of systems serve the basis for diagnosing nonlinear devices and systems with dynamic chaos with a stepwise piecewise linear characteristic of a nonlinear element according to the signals they generate.

Introduction. For 47 years of largescale implementation of breeding seed production programs in many regions of Siberia, geneticbreeding pools (GBP) of conifers have been created, but their development was stopped in the 1990s. Therefore, there is a need to summarize the accumulated experience and develop the new programs. The purpose of this research is to analyze the state of GBP of coniferous species of Novosibirsk region and to develop the new programs taking into account the latest achievements of forest genetics. Objects and research methods. The structure of the GBP was studied using the available literature data and the stock materials provided by the Ministry of Natural Resources and Ecology of the Novosibirsk Region. Assessment of the condition of objects and measurement of trees was carried out in 2018 using the generally accepted methods. When assessing the area of plantations, the preservation of trees, and the degree of closure of crowns on the plantations of the Elbashi breeding nursery, the satellite data from Pleades with a resolution of 0.5 meters were additionally used. Results and discussion. Novosibirsk region is distinguished with the use of all forestforming conifers in the breeding programs: Pinus sylvestris, Pinus sibirica, Larix sibirica, Picea obovta and Abies sibirica. Among the nature objects that perform the functions of preserving the gene pool in situ, there are 2585 ha of genetic reserves, 130.6 ha of plus stands, and 592 plus trees (PT). Among 225 ha of plantation trees, firstgeneration of forest seed orchards (FSO) and clone archives of plustrees of P. sylvestris and P. sibirica prevail. There are also about 15 ha of the most representative for the Siberian Federal District on the number and age of offspring of test plantation of plus trees and 15 ha of provenance trial plantations of P. sylvestris. The major shortcomings of the objects and the reasons that cause them are identified. The need in forest enterprises for the improved forest seeds is analyzed. The promising modifications of the methods are considered. Conclusion. In connection with the long interruption in the development of forest seed production in Siberia, it is necessary to consolidate the efforts and finances by analyzing the state of the created GBP and by developing the updated programs that take into account the accumulated domestic and world experience in this field. As an example, the fundamental provisions of these programs are formulated, arising from an analysis of the state and the methods used to establish the GBP of coniferous species in the Novosibirsk region.

From Non-Classical to Classical: Crystallization Seeds Reshape Nucleation Mechanisms

Published: February 2025

Crystalline seeds are widely employed in crystallization to accelerate nucleation and control product polymorphs, yet their impact on nucleation mechanisms remains poorly understood. While homogeneous nucleation of crystals from solution often proceeds through non-classical pathways involving amorphous intermediates, it is unclear how seeds that promote heterogeneous nucleation reshape these mechanisms and govern polymorph selection. Here, we provide the first direct evidence that crystalline seeds can bypass amorphous intermediates, converting non-classical nucleation mechanisms into classical, monomer-by-monomer crystallization pathways. Using molecular dynamics simulations of zeolite synthesis, we uncover a complex reaction network of competing nucleation processes mediated by intermediate interfacial polymorphs. The interplay between thermodynamic stability and kinetic favorability of these interfacial polymorphs dictates nucleation outcomes, creating a dynamic tension between interfacial polymorph stability and crystallization rates. Fur-thermore, we show that the synthesis environment—whether monomers or aggregates serve as reactants—profoundly impacts these pathways. At moderate supersaturation, seeds eliminate amorphous intermediates and promote classical nucleation, whereas high super-saturation or aggregate-based reactants favor non-classical pathways, even in the presence of a seed. These findings establish a general framework for understanding how seeds govern crystallization mechanisms, with broad implications for controlling nucleation kinetics, polymorph selection, and material properties. While focused on zeolites, this work reveals insights applicable to biominerals, pharmaceu-ticals, functional materials, and catalysts, providing a basis for engineering crystallization pathways in diverse applications.

Thio-lithium superionic conductors (thio-LISICONs) are a family of promising solid electrolyte materials for potential applications in solid-state batteries. The orthorhombic polymorph of the thio-LISICON Li4SiS4 (o-Li4SiS4) has been known for decades, but its complete crystal structure has been reported only recently. Here, using single crystal X-ray diffraction we reevaluated the crystal structure of o-Li4SiS4 and show that o-Li4SiS4 crystallizes in space group Pmn21 (No. 31, a = 7.7694(15) Å, b = 13.731(3) Å, c = 6.1413(12) Å). The crystal structure of o-Li4SiS4 consists of isolated SiS4 tetrahedra arranged in a zig-zag-type manner, whereas Li atoms are coordinated both tetrahedrally and octahedrally by sulfur atoms of the SiS4 groups. Structures identified by first-principles calculations support the lower symmetry solution presented here, with the Pmn21 polymorph being more stable at room temperature than a higher symmetry phase. By knowing the accurate crystal structure of o-Li4SiS4 we investigated the solid solution behavior with another group IV thio-LISICON, Li4SnS4. Rietveld refinements of powder X-ray diffraction data revealed the solid solution Li4Si1-xSnxS4 (0 ≤ x ≤ 1, Δx = 0.1), which shows a nearly ideal Vegard-type behavior for all silicon-containing samples. 29Si and 119Sn magic-angle-spinning solid-state NMR and Raman spectroscopy showed the presence of SiS4 and SnS4 tetrahedra moieties, with the spectra showing expected behavior consistent with the silicon-tin ratio in the materials. Electrochemical impedance spectroscopy revealed the highest ionic conductivity of 8.4×10-6 S cm-1 at 25 °C for Li4Si0.5Sn0.5S4, accompanied by the lowest migration barrier of ~0.37 eV.

This study investigated the effect of fermentation on the nutrient, anti-nutrient, and functional properties of cocoyam (Colocasia esculenta) flour at different time intervals. The tubers of Colocasia esculenta were processed and fermented at varying durations (24, 48, 72, and 96 hours), while an unfermented sample was retained as a control for comparative analysis. Subsequently, the fermented tubers were oven-dried at 65°C for 8 hours and milled into flour. Proximate composition, anti-nutritional factors and functional properties of the fermented and unfermented cocoyam flours were then evaluated. Results revealed an increase in Crude protein (15.11 to 19.81%) and carbohydrate levels (71.57 to 75.9%) with corresponding increase in fermentation time. While there was a reduction in moisture content (8.56 to 3.18%), crude fat (1.20 to 0.40%), fibre (0.73 to 0.21%) and ash content (2.87 to 0.49%) with corresponding increase in fermentation time. Anti-nutritional factors of fermented samples also reduced in a time-dependent manner. The result of the functional properties showed increase in water absorption capacity (0.27 to 0.87g/g), while a decrease was observed in bulk density (0.68 to 0.56g/ml), oil absorption capacity (3.47 to 1.04g/g), gelation temperature (85.35 to 83.92°C) and foaming capacity (15.54 to 9.52%). These changes suggest that fermentation can improve the nutritional quality and functionality of cocoyam flour, making it suitable for various food applications.

Organic optoelectronic materials (OOMs) are pivotal for advancing technologies such as organic photovoltaics and light-emitting diodes. Traditional methods for discovering new OOMs are inefficient and limited by chemical space exploration. We introduce O2-GEN, a novel framework leveraging a 3D pretraining backbone trained on a diverse dataset of over ten million molecules, enabling comprehensive exploration of chemical space. O2-GEN excels in generating fused-ring systems and conjugated fragment assemblies, achieving nearly 100% validity and novelty. It significantly outperforms existing models in speed and chemical structural validity, particularly for larger molecules. The framework supports both global and local generation modes, allowing for the creation of new molecules or modifications of existing structures. Additionally, O2-GEN integrates a property selector finetuned with density functional theory data, enabling precise multi-property screening. This framework offers a powerful tool for rational design and high-throughput screening of OOMs, with potential applications to drug discovery and energy materials.
Empirical Evidence for Fermi-Dirac Classification of Minerals by Particle Size
Authors: Starrett Joshua B. , Iveson Simon M. , Galvin Kevin P.
Published: February 2025

In mineral processing, partition curves are used to describe the probability of a particle of a given size or density reporting to the overflow or the underflow stream. One simple descriptor is the Rosin-Rammler (Weibull) functional form, based on a sharpness parameter, alpha. An alternative descriptor was introduced by Scott and Napier-Munn (1992) based on the Whiten equation expressed in terms of the Ecart Probable, Ep. This paper examines the Fermi-Dirac distribution (Fermi, 1926; Dirac, 1926) used in quantum mechanics, identifying for the first time its equivalence to the simplified Whiten equation. Fermions are quantum particles that must choose between two electron spin states, exhibiting a probability that varies with a chemical potential difference. We see an analogy with the particle size classification of an efficient separator in terms of the probability of a particle reporting to either the overflow or the underflow. The particle size classification data from Starrett and Galvin (2023), produced using the REFLUX™ Classifier, provided powerful empirical evidence supporting the application of the simplified Whiten equation (Fermi-Dirac distribution) over the commonly used Rosin-Rammler function. The raw data adhered to the distribution over a range of ±5Ep.

COMMUNICATION IN ENGLISH MEDIUM INSTRUCTION (EMI) CLASSES: AN INVESTIGATION INTO THE USE OF REPETITION STRATEGY FOR MEANING CO-CONSTRUCTION
Authors: Thi Lien Ngo Huong , Ngo Phuong Le Hoang , Van Nguyen Huy
Published: February 2025

The rising popularity of English-Medium Instruction (EMI) programs around the world has brought people of different linguacultural backgrounds into the same classroom. In such diverse settings, English is employed as a lingua franca (ELF) for academic communication. However, given the disparate levels of English and the academically demanding nature of higher education, many challenges exist that might hinder comprehension and cooperation in the classroom. For this reason, this paper seeks to investigate the use of repetition as a pragmatic strategy to facilitate ELF communication in EMI classes. The data was gathered from six lectures of a Business Administration course taught by an American lecturer to a class of third-year Economics-majored students, all of whom were Vietnamese.  The resulting eighteen hours of classroom recordings data were then transcribed and analyzed qualitatively. Findings reveal that various types of repetition were employed to realize seven specific means: highlight key information, organize discourse, elaborate on problematic terms, enhance clariry, show solidarity and alignment, improve mutual intelligibility, and show encouragement. This has pedagogical implications for training programs of both pre-service and in-service EMI lecturers.

Published: February 2025

A geophysical study of the failed portion of the Ado-Ikere-Ekiti road along Km5 was conducted to investigate the causes of its failure and proffer appropriate solutions to stop the failure. Vertical Electrical Sounding (VES), 2D Electrical Resistivity Tomography (ERT), and Electromagnetic (EM) impact survey using Schlumberger, Dipole-Dipole, and Gradient arrays respectively were employed for the study. VES data were interpreted quantitatively by partial curve matching and computer-assisted forward modeling using the IPI2Win(R) software. The geo-electric parameters obtained from the VES interpretation were used to generate a geo-electric section beneath the traverse. The 2-D subsurface resistivity structures of the failed portion of the road were obtained by processing and interpreting the data obtained from the ERT quantitatively employing the inverse modeling with DIPRO for Windows software. The EM survey electromagnetic fields were transmitted into the ground at varying frequencies to generate an output of frequency effect in percentage which is interpreted as apparent resistivity. The 1D EM geo-section generated by the instrument was used to delineate different formations like clayey/weathered, partly weathered, fractured basement, and fresh basement. The VES soundings produced different geo-electric curve types including the H, K, HA, HK, and KHA types. The geo-electric section revealed four subsurface geo-electric layers including the topsoil, weathered zone, fresh basement, and fractured basement. The topsoil resistivity values ranged from 249-685 ohms-m with a thickness range of 0.6 – 12.8 m. The topsoil is made up of lateritic-sandy soil. The second layer is the weathered zone with resistivity values ranging from 52 – 230 ohms-m and thickness from 0.7- 31.2 m. The third layer is the fresh basement with resistivity values ranging from 532-2866 ohms-m. The fourth layer constitutes the fractured zone of the study area with resistivity values of 269 – 422 ohms-m. The dipole-dipole arrangement revealed a hollow structure that suggested the possibility of a buried stream channel across the study area in an East-West direction. The EM survey confirmed the findings of the electrical resistivity surveys revealing highly weathered zones and the occurrence of deep fractured bedrock even at greater depth. It further confirmed the possibility of the buried river channel in the area. This study showed the possible causes of road failure to be the presence of a thin competent lateritic layer underlain by the thick weathered zone, the presence of fractured zones beneath the weathered zone, and lack of proper drainage at the road embankment. Suggested solutions to this problem include employing stabilization methods (compaction, grouting, or chemical stabilization) for the weathered zones, rock bolting, and grouting for the fractures and putting up drainage systems at the road embankments.

This study looked at the behaviour of Equatorial Total Electron Content (TEC) in connection to geomagnetic storms that occurred between January and March of 2020. The data used in the study came from the Global Positioning System (GPS). Vertical Total Electron Content (VTEC) data was collected at three different ground stations to conduct the investigation: NKLG (GMAGLat. -8.04°S, GMAGLong. 81.05°E), ADIS (GMAGLat. 1.13°N, GMAGLong. 110.47°E), and DJIG (GMAGLat. 3.36°N, GMAGLong. 11457°E). The locations were carefully chosen in order to offer a comprehensive picture of the equatorial ionosphere’s response to magnetic storms. The study’s findings show that the equatorial region undergoes both amplification and depletion effects in the reaction of TEC to geomagnetic storms. The paper also proposed possible approaches to clarify these findings. The three stations’ different latitudinal positions were recognised as the principal source of the considerable variations in GPS-TEC responses during storm periods. Furthermore, during the storm periods, the peak positive percentage deviation of TEC displayed an ascending trend with rising altitude for each monitoring station. This finding suggests the existence of complex height-related interactions between the equatorial ionosphere and geomagnetic storms. The current study examines the complicated factors that influence the behaviour of TEC in equatorial regions during geomagnetic storms. It highlights the need of adding latitudinal and altitude factors in such studies.

Authors: Subedi Sandesh
Published: February 2025

Algae are a diverse group of unicellular autotropic microorganisms. It is a free-floating and filament-shaped organism, in which the blade is the main site for photosynthesis. Hence, called a photosynthetic organism. Different types of algae are found in different types of climatic conditions. Algae are found in almost all adverse climates. Due to its vast chemical composition and content of bioactive substances attention of different industries like food, cosmetic pharmaceuticals, nutraceuticals, etc. are caught by it. Algae food products contain a high amount of nutrients, and cosmetic products protect from UV radiation and prevention of rough texture wrinkles of the skin, as they carry out both photosynthesis as well as nitrogen fixation, add organic matter (20 -30kg/ha/year)and maintain texture porosity, the structure of soil and can play an important role for reducing the problem of petrol, diesel. This review has been prepared to shed light on the wide uses of algae as food, fuel, cosmetic product biofertilizer and also to provide knowledge about different types of algae found in different geographical zones of Nepal.

Published: February 2025

The development of local self-government is essential for fostering citizen participation in ad-dressing regional issues, enhancing civic engagement, deepening democracy within the political sys-tem, and increasing citizens’ understanding of the decision-making process at the state level. In Ka-zakhstan, several significant decisions have been made in recent years, including the introduction of a fourth level of the budget and the direct election of aul akims (mayors of villages, towns, and cities that are subordinate to districts) by residents. These initiatives aim to strengthen local self-government. The reforms implemented have stimulated scientific research to assess the effectiveness of public policy in this area. This study evaluates recent publications on local self-government in Kazakhstan through literature reviews. Consequently, the authors present several conclusions and recommendations for broader discussion. These recommendations are beneficial not only for evaluating recent government reforms but also for outlining future directions for policymakers and potential research avenues for academics.

The Limitations of Social Reproduction Theory in Explaining Social Unpaid Work in the Global South
Authors: Liu Yuqian
Published: February 2025

This paper defines and explores the concept of social reproduction work, highlighting its significance and the fact that women are its primary contributors. It identifies key social issues faced by social reproduction workers, including marginalization, neglect, and unequal access to resources. Additionally, the study examines the primary challenges encountered by these workers: the lack of direct economic benefits, difficulty in balancing work and family responsibilities, and the significant physical and mental strain associated with unpaid labor. Using the theoretical framework of the capitalist economic system, the paper delves into the root causes of the caregiving crisis. Furthermore, it critiques the applicability of reproduction work theories in explaining unpaid care work in the Global South. Three key limitations are outlined: the neglect of informal economic systems in the Global South, persistent gender inequality, and the dynamic nature of global economic migration.
THE EFFECT OF ADDING ELECTROLYTES (NACL) IN TUNJUNG MORDAN ON ECOPRINT RESULTS USING JATROPA CURCAS LINN LEAVES WITH POUNDING TECHNIQUE ON CHIFFON MATERIAL
Authors: Ramadhani Mitra , Adriani Adriani
Published: February 2025

This research is motivated by the use of jatropha leaves to make motifs with the ecoprint technique. The purpose of this study is to describe the color name, color fastness and the effect of adding electrolyte to the tunjung mordan on the results of ecoprint by pounding technique on chiffon material. The type of research is experimental research with primary data types sourced from filling out a questionnaire of 18 panelists. Ecoprint of jatropha leaves without mordan produces the names of canary yellow on leaf sheets, pale golden on leaf bones, and reef green leaf bone branches. With mordan tunjung produces dark olive green on the leaf sheet, canary yellow on the leaf bone mother, and reef green on the leaf bone branch. The addition of electrolytes to the tunjung mordan produced the name of camouflage green on the leaf leaf, green smoke on the leaf bone, and reef green on the leaf bone branch. The color fading resistance to washing in chiffon material without mordan, in mordan tunjung, and the addition of electrolyte to mordan tunjung 1time and 2times Ho washing was declared accepted, meaning that there was no significant difference in the results of the K-Related Sample test on color fastness to washing. While 3times of washing Ho was rejected, it means that there is a significant difference in the results of the K-Related Sample test on color fastness to washing.
THE POETICS OF THE ENUMERATION IN AN EPIC AND LYRIC TEXT (“QUEUE” BY G. SAPGIR AND “QUEUE” BY V. SOROKIN)
Authors:   Tver State University, Artemova Svetlana Yu. , Krasotkin Dmitry M. ,   Tver State University
Published: February 2025

The article is concerned with the issue of the enumeration of
grammatically homogeneous elements and the function of that enumeration in
epic and lyrics. Repetition, including repetition with variations, is recognized
as one of the fundamental elements of a literary text. We will be interested in
repetition grammatically and partly syntactically, as a syntactic reproduction
of grammatically similar structures (an example is the so-called “infinitive writing” by Zholkovsky or the principle of “verblessness” by M. Gasparov). It will
also not be possible to describe their diversity in one article, so we will focus on
the very principle of repeating grammatically homogeneous elements and we
will show how this principle works in epic (using the example of Sorokin’s novel
“Queue”) and in lyrics (using the example of Sapgir’s poem of the same name).
The sequence of the queue’s replicas in Sorokin generates narrativity, building
the whole from parts, philosophical generalization, and “accumulation”. Overcoming heterogeneity and diversity is carried out through narrative and plot
schemes. In Sapgir’s poetry, the list of grammatically homogeneous structures
(words and sentences) shows the impossibility, absurdity of the whole, irony
in relation to philosophical generalization. The repetition of words, the same or
grammatically similar, but different, reveals the complexity and versatility of
the world, it’s irreducibility to a single pattern.
CHRONOTOPIC PATTERNS IN RUSSIAN ROCK POETRY
Authors:   Russian State Hydrometeorological University, Grigorieva Anastasia V.
Published: February 2025

The article considers patterns that can be identified when analyzing the Russian rock poetry in the prism of a chronotope, called “chronotopic
patterns”. The spatio-temporal-semantic connection underlying the concept
of “chronotope” can be identified in many works by Russian rock poets. In
the course of the present study, we attempted to classify stable chronotopic
images in accordance with deterministic nominations based on the ultimately
generated meanings in the text of rock poets. Of interest is the range of forms
that the chronotope can acquire in a rock text due to the verbalization and
concretization of time and space. The plot-forming function of the chronotope
is due to the importance of the coordinates of space and time in the coordinate
plane of the work of art, along with images, but the key role is played by the
perception of time and space by both the lyrical characters and the recipient,
which underlies the principle of the author’s influence and forms the holistic
unique concept of the rock work. Chronotopic patterns as repeating stable patterns of thinking have different ways of manifestation, concretized by certain
nominations at the lexical level, either of which contains a deep meaning and
a key to understanding the work as a whole, becoming a springboard for the
development of the plot.

Published: February 2025

The article summarizes the results of analyzing the systemic relations of the category “observer” with the levels of artistic work: focal, glossal,
plot, compositional, rhythmo- and mythotectonic, – which are considered
through the prism of the methodology of functional pragmatism. The levels are
typologized in accordance with three dimensions: concreteness – abstraction;
isolation – fusion of aesthetic subject, object and addressee; meaning – text.
