The purpose of the work is to follow the dynamics of changes in fluorescent signals in the near-surface layers of tissue of injured areas of the back of laboratory animals, which will allow, by indirect evidence, to evaluate the information content of fluorescence diagnosis for subsequent possible diagnostic monitoring of photodynamic therapy of the spinal cord. The model animals were Wistar rats. Two types of contusions were modeled: pneumo-contusion and contusion by a falling load. Methylene blue and indocyanine green were used as photosensitizers. Fluorescence measurements were carried out by imaging and spectrometric methods. A stroboscopic fluorescence imager with an excitation wavelength of 630 nm was used to acquire fluorescence images. The LESA-01-BIOSPEC spectrometer with a He-Ne laser excitation allowed to obtain spectra. It was shown that both methods make it possible to estimate the fluorescence value of methylene blue and indocyanine green in the tissues under study. Moreover, the photographic method also allows to obtain the spatial distribution of fluorescence. The general trend found in the data is a more intense and uniform fluorescence of the dorsal region of rats with methylene blue and a less intense, but more contrasting distribution of indocyanine green. The presented methods are non-invasive, which makes them attractive for diagnostic use. However, due to the shallow depth of signal reception, the condition of the spine can be determined only indirectly, by the condition of the near-surface layers of tissue that accumulate the photosensitizer.

Published: October 2023

Purpose. In the history of the development of Russian fortification architecture in Siberia in the era of Peter I, the most unique situation and bright page should be considered the construction in a short time of a line of 930 miles fortresses along the right bank of the Middle and Upper Irtysh from the Omsk fortress to the Ust-Kamennaya. For Siberia, this was a unique situation, since previously fortified lines had not been created here. Therefore, it is important to study and characterize the natural and geographical conditions of the Russian development of the region.Results. This study is devoted to resolving a complex of problems related to the history and archaeology of the fortification of the Petrine time along the Middle Irtysh (within the modern Cherlak district of the Omsk region). Here we have passed the water and foot routes. In the course of the work, natural conditions for the placement of defensive objects and their search at the present time, the state and types of communication routs, the presence of scaffolding in the immediate vicinity, stone and ore resources, etc. were consideredConclusion. In general, the passed route provided significant scientific results, which made it possible to objectively characterize the conditions of the territory development in the Middle Irtysh by Russians in the time of Peter the Great. As a result of the study, we were able to significantly clarify the history of the emergence and reconstruction of the fortification objects: the Solianoi Povorot and Krutoyarka villages. Prospects for further study of these sites are associated with archaeological excavations.

Published: October 2023

Purpose. Russian rural archeology of the Verkhneobskoi Region is a potentially promising area of scientific research, so any materials related to it must be introduced into scientific circulation in a timely manner. However, the number of publications on this topic in the region is still very small. This article presents archaeological finds from the cultural layer of the village of Povalikha, founded in 1719 in the department of the Beloyarskaya fortress (the Altai Region).Results. Four archaeologically intact vessels were found. Three vessels are unique in their shape and have a recess from the rim to the bottom, the question of their purpose remains controversial. A copper coin of 1739 was found in one of them. A summary of the numismatic complex discovered in the village is given. Individual fragments of ceramic vessels, a birch bark back from shoes and a fishing hook have been studied. The authors discuss a need for a broader study of Russian settlements of the 18th century located in the Altai Region.Conclusion. The authors conclude that the accidental discovery of representative artifacts indicates the clear prospect of thorough reconnaissance studies in the territory of the village of Povalikha. At the same time, it should be noted that the archaeological study of life support systems and the culture of everyday life of the Russian pioneers in the Verkhneobskoy Region is largely at the stage of initial accumulation of materials.

Purpose. The paper presents a description of the stratigraphic and planigraphic situation at the excavation 3 of the Lakhuti IV site (Khovaling loess plateau, Tajikistan) recorded during field work in 2022.Results. The cross-section has 18 layers grouped into three strata: L6 glacial period sediments (MIS 14), 6a and 6b soil complexes (MIS 15). The identified technocomplexes belong to the late Karatau culture of the Lower Paleolithic of Tajikistan. The level 5.2 planigraphy indicates that the investigated area could be a fragment of a workshop site where primary processing of stone raw materials was carried out. The layer L6 artefacts indicates that the region was continuously developed by humans, and glacial conditions in the Middle Pleistocene affected the intensity of these processes only.Conclusions. The closest analogues to the late Karatau complexes can be traced in the Soan pebble-flake industries of the Northern Hindustan. They have a similar age to Tajik materials (second half of the Middle Pleistocene), geomorphological position (deposits of high terraces in the upper reaches of the Indus, Soan, and other rivers in the Himalayas foothill zone), a similar raw material base (river alluvium). Also they have a number of technical and typological characteristics, which include: citron and radial knapping; a higher percentage of large flakes and “citrons”; choppers, simple side-scrapers and unifaces in tool-kits; lack of bifacial technique. As a result of a new stage in the study of the Lower Paleolithic complexes in the region, authors proposed a new model, according to which the region was continuously developed by hominins, and glacial conditions mainly influenced the intensity of these processes.
Non-Ceramic Site of Shamanka 8 on the Southern Coast of Baikal Lake
Authors: Kuznetsov A. M. , Molchanov D. N. , Bazalysky V. I. , Abrashina M. E. 
Published: October 2023

Purpose. The southern coast of lake Baikal is a territory known in Siberian archaeology for its Kitoi cemeteries. Besides burials of the Shaman capes there are some Neolithic and Bronze age complexes at Circum–Baikal railway. In 2012 it the first non-ceramic site was discovered in South Baikal, which was named Shamanka 8. This paper presents the assemblage of this complex and discusses its chronological and cultural features.Results. The Shamanka 8 site is located on the top of the third hill of the Shaman cape. The cultural layer lies under the Holocene Optimum sediments. The site stratigraphic structure is characterized by compression. There is no bone fragments and ceramic. For lithic knapping, mainly local raw material (quartz) were used. The quartz assemblage has such features as poor formal standardization, high degree of flake fragmentation, cores with the orientation of fracture plane relative to the longitudinal axis, bipolar reduction. All of these specifics are explained by uneven fracture characteristics and bad workability of quartz, as well as its breakage patterns. Some artifacts, including single non-quartz tool, suggest that there may be a connection between the Shamanka 8 site and the industries of the Final Paleolithic sites in the Northern Baikal region and the Irkutsk region. Quartz small knife (?), carinated end-scraper and tubular core have analogies in the 2nd cultural layer of the Kurla II site, dated by 13.5 uncal kya. Similarly dated quartz components of Nirikan I and flint tool-kit of Verkholenskaya Gora I include other cultural link types.Conclusion. The similarity in the morphology of some tools with Final Paleolithic counterparts and stratigraphic position of finds allow us to assume the Final Sartan age of the Shamanka 8 site and dates it to the Bølling – Allerød warming. However, in the absence of direct radiocarbon dating, an Early Holocene/Early Neolithic attribution of the site is also possible. Further studies may help resolve this issue.
Functional and Technological Analysis of Artifacts from the “Foundryman’s Burial” of the Sopka-2 Burial Ground
Authors: Molodin V. I. , Volkov P. V. , Durakov I. A. 
Published: October 2023

Purpose. The article is devoted to the use-ware study of the accompanying inventory from the unique “foundryman’s burial” burial no. 282 of the Sopka-2 burial ground. A significant tools collection was found in the burial, including crucibles and molds intended for the manufacturing Seima-Turbino celts, as well as bronze Seima-Turbino celt. Three types of artefacts were distinguished: made of stone, organic materials (bone and horn) and ceramic.As a result of the use-ware analysis, the nature of the use of tools and their purpose have been determined. Most of the collection items had already been used as tools (molds, chisels, abrasives, spatulas, bow linings) before they were put in the “foundryman’s grave”. However, some of the artifacts were unfinished or not used (casting funnel, blanks for them, arrowheads). It should also be noted that there are broken and unusable artefacts in the collection.

Purpose. The Sargat culture fish remains are still given very little attention. The purpose of this work is to present materials that testify to the use of fish in the burial practice of the Sargat population of Baraba.Finds (artefacts). In the field season of 2022, the Toguchin team of the IAET SB RAS explored the mound no. 51 of the Ust-Tartas burial ground of the Sargat culture. Among the various artifacts found on the mound territory there were objects containing animal bones, and objects containing fish remains, as well as objects containing both animal bones and fish remains.Methods. Preparation of the osteological collection of fish remains was carried out in 2022–2023 using a cameral processing method. The collection contains mainly scales, bones of the visceral part of the skeleton of the head, bones of the skull. Fragments of the axial skeleton (vertebrae, Weberian apparatus, urostyle) and pharyngeal teeth appear in a smaller number. In the pocess of the collection formation, it was found that the best preservation of samples is ensured by materials that have not been preliminary washed and cleaned: the bone structures are less brittle. Therefore, fragments of the fish skeleton were separated from the soil in the laboratory.Results. For the most part, accumulations of fish remains are represented by large specimens of older age groups (from 7+ years, mostly 10+ and more). The identified species composition of fish in samples of the Early Iron Age includes representatives of the family Cyprinidae (ide Leuciscus idus, goldfish Carassius gibelio) and family Percidae (perch Perca fluviatilis). In addition to the listed species, remains of the family Acipenseridae (sterlet Acipenser ruthenus) and the family Cyprinidae (golden crucian carp C. Carassius) were noted in the earlier objects. Object 10 stands out: it is a butt containing not only tools and animal bones, but also fish remains. For the first time, the fact of fish use in the funeral rite of the Sargatians was revealed. The fish remains in the mound testify that the population of the Sargat culture who created this site practiced fishing along with their main occupation – cattle breeding.Conclusion. Materials of the mound no. 51 of the Ust-Tartas burial ground, containing fish remains, are an example of the local population adaptation to the natural environment. The Tai tract was a natural oasis, which not only provided a forage base for livestock but also ensured an easy catch of fish. Human adaptation to the natural conditions in the Baraba region was quite successful, as evidenced by the fact that fish was a part of the funeral rite along with products of animal origin. It was often included in butts in some objects, which correlates with sacred actions.

Métaverse, cette « vérité » communément admise devient encore plus évidente face à l’émergence des structures et mondes parallèles au sein de ces univers virtuels. Cependant, cet avenir très proche marqué par ces métaverses nous préoccupe, et rien ne semble pouvoir les empêcher de devenir une réalité. En effet, ces nouveaux territoires intangibles pourraient changer fondamentalement notre façon d’être et d’exister nous menant à questionner particulièrement leur impact sur nos processus cognitifs et affectifs ainsi que le rapport que nous entretenons les uns avec les autres. Cela nous mène en tant que chercheure designer de passer d’une posture théorique et spéculative à une posture plus active et participative afin d’explorer et de comprendre empiriquement cet impact dans le cadre d’une première étude exploratoire se basant sur un croisement entre le design et les neurosciences. Dans le cadre d’une expérimentation de l’expérimentation et afin d’explorer l’activité cérébrale des utilisateurs, ce travail présente une méthode de mesure neurophysiologique en utilisant le casque emotiv.
On one data structure for grid-based clustering of multispectral images
Authors: Рылов С.А. 
Published: October 2023

Рассмотрена проблема применения сеточных алгоритмов кластеризации к данным высокой размерности, возникающая из-за экспоненциальной зависимости объема сеточной структуры от размерности пространства признаков. Представлен обзор сеточных алгоритмов кластеризации. Предложена новая структура данных для хранения многомерной сеточной структуры, позволяющая сократить требуемый объем памяти с помощью перехода к хранению только непустых ячеек. Для сравнения были реализованы еще два подхода на основе использования хештаблиц. Выполнены экспериментальные исследования по сеточной кластеризации мультиспектральных спутниковых изображений с использованием реализованных структур. Проведено сравнение времени вычислений и объемов занимаемой оперативной памяти. Установлено, что рассматриваемые сеточные структуры позволя ют проводить обработку данных высокой размерности (от 5 до 10) с адекватными затратами памяти. Предложенная структура данных показала себя лучше других.
Grid-based clustering algorithms allow processing large data arrays and distinguish clusters of complex, a priori unknown shape. However, grid-based algorithms remain computationally efficient only while the feature space dimensionality is small. This paper considers the problem of applying grid-based clustering to high-dimensional data, which arises due to the exponential growth for the size of grid structure with the feature space dimensionality. The common “greedy” approach, which stores information about each cell of the grid structure, requires unacceptably large memory costs in high dimensional cases. In this paper a new data structure for storing multidimensional grid structure that considers only non-empty cells is proposed, which allows reducing the dependence of memory costs on the data dimension. The proposed data structure stores only a subspace of a grid structure in the expanded form. Besides, two multidimensional grid structures were implemented based on the use of hash tables. All developed structures were adjusted according to the HCA clustering algorithm and also may be used in other grid-based algorithms. Experimental studies were carried out in terms of memory costs and computation time on WorldView-2 and Sentinel-2 multispectral satellite images. The obtained results have showed that all three implemented data structures allow grid-based algorithms for processing high-dimensional data with reasonable memory costs. At the same time, the proposed data structure have showed better results than other implemented approaches. Thus, the conducted study allows expanding limits of the grid-based clustering algorithms in processing high-dimensional data (5–10 dimensions).
