Published: October 2020

In video streaming over vehicular communication, optimal selection of a video packet forwarder is a daunting issue due to the dynamic nature of Vehicular Ad-hoc NETworks (VANETs)and the high data rates of video. In most of the existing studies, extensive considerations of the essential metrics have not been considered. In order to achieve quality video streaming in vehicular network, important metrics for link connectivity and bandwidth efficiency need to be employed to minimize video packet error and losses. In order to address the aforementioned issues, a Road-based Multi-metric Forwarder Evaluation scheme for Multipath Video Streaming (RMF-MVS) has been proposed. The RMF-MVS scheme is adapted to be a Dynamic Self-Weighting score (DSW) (RMF-MVS+DSW) for forwarder vehicle selection. The scheme is based on multipath transmission. The performance of the scheme is evaluated using Peak Signal to Noise Ratio (PSNR), Structural SIMilarity index (SSIM), Packet Loss Ratio (PLR) and End-to-End Delay (E2ED) metrics. The proposed scheme is compared against two baseline schemes including Multipath Solution with Link and Node Disjoint (MSLND) and Multimedia Multi-metric Map-aware Routing Protocol (3MRP) with DSW (3MRP+DSW). The comparative performance assessment results justify the benefit of the proposed scheme based on various video streaming related metrics.

Authors: Kim Yoon-Ki , Kim Yongsung
Published: October 2020

Recently, as the amount of real-time video streaming data has increased, distributed parallel processing systems have rapidly evolved to process large-scale data. In addition, with an increase in the scale of computing resources constituting the distributed parallel processing system, the orchestration of technology has become crucial for proper management of computing resources, in terms of allocating computing resources, setting up a programming environment, and deploying user applications. In this paper, we present a new distributed parallel processing platform for real-time large-scale image processing based on deep learning model inference, called DiPLIP. It provides a scheme for large-scale real-time image inference using buffer layer and a scalable parallel processing environment according to the size of the stream image. It allows users to easily process trained deep learning models for processing real-time images in a distributed parallel processing environment at high speeds, through the distribution of the virtual machine container.
Lateral-Acceleration-Based Vehicle-Models-Blending for Automated Driving Controllers

Published: October 2020

Model-based trajectory tracking has become a widely used technique for automated driving system applications. A critical design decision is the proper selection of a vehicle model that achieves the best trade-off between real-time capability and robustness. Blending different types of vehicle models is a recent practice to increase the operating range of model-based trajectory tracking control applications. However, current approaches focus on the use of longitudinal speed as the blending parameter, with a formal procedure to tune and select its parameters still lacking. This work presents a novel approach based on lateral accelerations, along with a formal procedure and criteria to tune and select blending parameters, for its use on model-based predictive controllers for autonomous driving. An electric passenger bus traveling at different speeds over urban routes is proposed as a case study. Results demonstrate that the lateral acceleration, which is proportional to the lateral forces that differentiate kinematic and dynamic models, is a more appropriate model-switching enabler than the currently used longitudinal velocity. Moreover, the advanced procedure to define blending parameters is shown to be effective. Finally, a smooth blending method offers better tracking results versus sudden model switching ones and non-blending techniques.
Modeling of Forest Communities’ Spatial Structure at the Regional Level through Remote Sensing and Field Sampling: Constraints and Solutions
Authors: Kotlov Ivan , Chernenkova Tatiana
Published: October 2020

This study tests modern approaches to spatial modeling of forest communities at the regional level based on a supervised classification. The study is conducted by the example of mapping the composition of forest communities in a large urbanized region (the Moscow Region, area 4.69 million hectares). A database of 1684 field descriptions is used as sample plots. As environmental variables, Landsat spectral reflectances, vegetation indices (5 images), digital elevation model and morphometric parameters of the relief, 54 layers in total, are used. Additionally, the Palsar-2 radar dataset is included. The main mapped units are formations and groups of associations identified on the basis of the ecological-phytocoenotic classification. Formations and groups of associations are similar in semantics and principles of allocation to units of forest typology. It is shown that the maximum entropy method has a wide range of applications, in particular, for mapping the typological diversity of forest cover. The method is used in combination with geographically structured spatial jack-knifing, spatial rarefication of occurrence data and independent testing of model feature classes and regularization parameters. Spatial rarefication is a critical technique when points are not evenly distributed in space. The resulting model of the spatial structure of forest cover is based on the integration of the best models of each thematic class of different types of forest cover into a single cartographic layer. It is shown that under conditions of uneven and sparse distribution of points, it is possible to provide an average point matching level of 0.45 for formations and 0.29 for association groups. Herewith, the spatial structure and the ratio of the formation’s composition correspond to the official data of the forest inventory. An attempt is made to identify and evaluate the distribution of more detailed syntaxonomic units: association groups. The necessary requirements for improving the quality of the forest cover model of the study area for 2 hierarchical typological units of forest cover are formulated. These include the additional sampling in order to equalize their spatial density, as well as to achieve equality of samples based on stratification according to the resulting map.
A Generic Shear Wave Velocity Profiling Model for Use in Ground Motion Simulation
Authors: Tang Yuxiang , Xiang Xinmei , Sun Jing , Zhang Yongshan
Published: October 2020

This study presents a generic model for constructing shear-wave velocity (VS) profiles for various conditions that can be used for modeling the upper-crustal modification effects in ground motion simulations for seismic hazard analysis. The piecewise P-wave velocity (VP) profiling model is adopted in the first place, and the VS profile model is obtained by combining the VP profiling model and VS/VP model. The used VS/VP model is constructed from various field measurements, experimental data, or CRUST1.0 data collected worldwide. By making the best use of the regionally/locally geological information, including the thickness of sedimentary and crystalline layers and reference VS values at specific depths, the VS profile can be constructed, and thus the amplification behavior of VS for a given earthquake scenario can be predicted. The generic model has been validated by four case studies of different target regions world around. The constructed profiles are found to be in fair agreement with field recordings. The frequency-dependent upper-crustal amplification factors are provided for use in stochastic ground motion simulations for each respective region. The proposed VS profiling model is proposed for region-specific use and can thus make the ground motion predictions to be partially non-ergodic.

Visiones abarcadores del pasado en la Mesopotamia antigua: el problemático equilibrio entre lo mítico y lo histórico
Authors: Seri Andrea
Published: October 2020

Documentos provenientes de tradiciones diversas muestran que en la Mesopotamia antigua el pasado se representaba de varias maneras. Entre esos textos se encuentran listas reales, narrativas con fuertes componentes míticos, composiciones con rasgos literarios evidentes, presagios que vinculan resultados positivos o nefastos con reyes icónicos, inscripciones reales que cuentan las hazañas de los gobernantes y, más tarde, aparecen los anales asirios que registran campañas reales. Surgen, también, las crónicas de contenido ecléctico. Los agentes de cambio son dioses que premian o castigan, soberanos implacables o el simple devenir. La veracidad de hechos y personajes del pasado, sean mitológicos, fantásticos o reales, no parece haber despertado demasiadas suspicacias. En este trabajo se analiza la manera en la que la Lista Real Sumeria y la Babiloniaca de Beroso entrelazan hechos y personajes ficticios y reales para ofrecer visiones abarcadoras del pasado en un juego de equilibro entre lo mítico y lo histórico.

Henoteísmo, politeísmo, monoteísmo. “Diálogo” de historia de las religiones antiguas
Authors: Lemardelé Christophe
Published: October 2020

Los estudios de historia de las religiones del Mediterráneo antiguo son tributarios de la vieja oposición teológica entre las nociones de politeísmo y de monoteísmo. O mejor, el monoteísmo es ante todo un hecho histórico próximo-oriental antes que una noción universal. En cuanto al politeísmo romano, evoluciona para el caso de los emperadores en un henoteísmo solar durante los primeros tiempos del Imperio. El exclusivismo histórico y antropológico del monoteísmo próximo-oriental, presente en el cristianismo, no podía sino coexistir con esta novedosa concepción filosófico-religiosa.

The main requirements for hydraulic equipment of forest transport machines of manipulator type are revealed. It is established that the main drawback of the used hydraulic drives of manipulators is their increased power and high energy consumption. The main ways of increasing the technical level of hydraulic manipulators of forest transport vehicles are considered. The constructive optimization and improvement of the hydraulic drive mechanism for lifting the boom and turning the column of the manipulator is justified. New designs with the use of hydro-mechanical dampers and energy-saving devices are proposed. As energy-saving devices, it is proposed to use a hydraulic accumulator. The main advantages of the design, which are to increase the reliability and expand the technological capabilities of hydraulic manipulators forest transport machines. The principles of influence on the hydraulic system that reduce the pressure in the piston group and reduce energy consumption are substantiated. The proposed energy-saving hydraulic drive reduces the maximum pressure during braking to 3 MPa. The recovery energy when the column is rotated is 25 % of the energy consumed. The diameter of the dampener's lockable cavities should be 48 mm with the internal diameter of the dampener 65 mm. Minimal changes in the design are achieved to increase the technical level of the hydraulic drive of manipulators of forest transport machines and its competitiveness among existing analogues.

Authors: Belchinskaya Larisa , Dmitrenkov A. , Zhuzhukin Konstantin
Published: October 2020

The article is devoted to the study of technologies for the use of used motor and vegetable oils for hydrophobizing treatment of birch wood. In this work, synthetic and semi-synthetic engine oil is used to impregnate wood; spent corn oil, sunflower oil, organosilicon liquid GKZh-11, industrial impregnating composition of ZhTK. The effectiveness of the impregnating compositions is estimated by the indicators of water absorption and swelling in two mutually perpendicular directions (radial, tangential). Spent motor and vegetable oils saturate wood quite well and give it hydrophobic properties. At the same time, impregnation of birch wood with used engine oil (OMM) allows to improve water absorption of birch wood by 52.1% compared to natural wood and by 21% compared to water absorption. Thus, the processing of birch wood with used motor and vegetable oils makes it possible to utilize production waste and improve the properties of low-value wood species with a significant increase in its resistance to external influences.

BASIC DIRECTIONS OF INNOVATIVE DEVELOPMENT OF THE FOREST PRODUCTS
Authors: Titova E. , Shevchenko A.
Published: October 2020

Currently, in accordance with the processes of globalization and global economic and environmental trends, the Russian government is focusing economic entities on the innovative development of the Russian economy. For the timber industry of the Russian Federation, which ranks first in the world in terms of timber reserves, a transition to innovative development is inevitable. This transition is due to the resource potential of the industry, global environmental trends of the "green economy", the prevailing market relations between the economic entities of the industry, the presence of a bank of scientific and technical and experimental development in the field of timber industry. The analysis of Russia's share in the global forestry market is carried out: the Russian Federation is the world leader in timber reserves, it has 1/5 of the world's forest reserves and, therefore, takes first place; Brazil ranks second in timber reserves, Canada is third and the United States is fourth. The structure of Russia's exports by product groups is examined: the country's most profitable budget item is the export of fuel and energy products, accounting for 64% of the total export structure, and only 3% of the export structure is the export of timber and paper products. Given the development trends of world oil markets and the geopolitical tensions of countries, it can be assumed that in the next 5 years, the total revenue of the Russian Federation from the export of fuel and energy products will significantly decrease and will cease to be the most profitable budget item in the country. Due to the fact that the Russian Federation is a world leader in timber reserves, we believe that the innovative development of the timber industry should be one of the leading areas in the industry development strategy of the Russian Federation, and accordingly in the export strategy of the Russian Federation. The main directions of the innovative development of the timber industry of the Russian Federation in the following sectors are identified: forestry, woodworking industry, pulp and paper industry, chemical production, logging, wooden housing construction.

DIGITAL TECHNOLOGIES AT ANALYSIS OF THE WOOD PLANTS STATE
Authors: Kamalova Nina , Matveev Nikolay , Ivannikov S.
Published: October 2020

The state of woody plants determines the viability of forests and environmental safety in urban environments largely. Therefore, scientific studies of the tree response as a complex biosystem on environmental factors changes are especially relevant due to the growing threat of environmental disasters (environmental pollution, active felling, etc.). Many modern methods for assessing the state of such complex macromolecular systems are verbal in nature due to the lack of non-destructive testing methods with controlled accuracy. The shortage of experimental measurements retards the development of modeling the state of trees and, consequently, the development of methods for predicting their response on the influence of external factors. The development of digital technology can change the current state of affairs in this sphere. In the report, within the framework of a systematic approach, the possibility of using digital technologies at analyzing the response of the state of woody plants on environmental factors changes has analyzed. The results of studying the flow of salt solutions in the xylem of tree trunks are presented to solve the problem. Based on experimental data, models are proposed that can become the basis of calculation systems for analyzing the state parameters of woody plants and predicting the occurrence of environmental disasters.

Published: October 2020

The work is devoted to the problems of greening the streets of the city of Voronezh. Trees and shrubs are designed to aesthetically transform the monotony of streets and roads, provide shading of sidewalks, protect passers-by and surrounding areas from dust, gases and noise from the roadway. At the same time, these plantations are experiencing the maximum pressure of vehicles and other anthropogenic factors. The ability of plantings to perform the most important ecological functions directly depends on their condition, which is greatly influenced by a set of environmental factors. With a properly selected assortment and proper placement of plants, the plantings ' resistance to biotic and anthropogenic factors increases, and the perception of the city as a whole improves. The paper presents the results of studying the range of plants growing along the main streets of the city of Voronezh. A complete inventory of plants was carried out, life forms, taxational indicators of trees and shrubs, their condition and systematic position were determined. The main types of plantings used in street gardening in the city of Voronezh are identified. It is shown that the rock composition of plantings is represented by 51 species that belong to 18 families. Deciduous tree species dominate the plantings, and shrubs and lianas are less common. In this case, the participation of coniferous plants is less than 1%. The dominant species in the plantings are pyramidal poplar, squat elm and hanging birch. The indicators of the qualitative state of these breeds are determined, the complex of pests and diseases is considered, and recommendations for optimizing street gardening in the city of Voronezh are presented.
ASPECTS OF THE GROWTH OF CRIMEAN PINE INTRODUCED IN HERB-GRASS AND MIXED-GRASS STEPPE ZONE OF VOLGA-DON DISTRICT OF THE SOUTH OF THE RUSSIAN PLAIN
Authors: Levin S. , Chernodubov Aleksey
Published: October 2020

Crimean pine (Pinus nigra subsp.pallasiana Lamb.) better than other introduced tree species fits the environmental conditions of the studied region, as it is highly resistant to various pathologies and can be used to form complex (multilayered) uneven-aged multispecies stands. The significant age of the studied stands (110 and 118 years old) provides a good indication of this fact, as well as allows us to make a judgement on the features of growth and development of Crimean pine mixed with Scots pine. It should be noted that when Crimean pine is mixed with Scots pine its average trunk volume is 2.5 times higher than that of pure Crimean pine stands. Research suggests that the best plant growth pattern for the steppe conditions is when Crimean pine strips are grown between the Scots pine strips. The best plant spacing is 2x1 m and at least 2 Crimean pine rows should be spaced between Scots pine rows. Such a pattern best suits the В2 site type according to Pogrebnyak’s classification which corresponds to mesophytic mixed forests.

Authors: Budina T.V. , Margaryan E.G. , Ovsienko A.G.
Published: October 2020

Systemic diseases of the body, including obstructive sleep apnea (OSA), play an essential role in the pathogenesis of chronic generalized periodontitis. The main dental symptom of OSA is dry mouth due to oral breathing, which is a significant risk factor for periodontal disease.
Purpose. Сlinical and laboratory assessment of periodontal tissues in patients with obstructive sleep apnea.
Material and methods. The subjects of our study were patients from 35 to 65 years old. In total, 40 patients with obstructive sleep apnea syndrome and 30 patients who made up the comparison group were examined. Patients with obstructive sleep apnea syndrome were divided into three groups according to the severity of apnea. The first group included patients of women and men with mild apnea, the second group of men and women with moderate apnea, and the third with severe obstructive sleep apnea. Gum bleeding was assessed by the Mulleman-Cowell index, the degree of inflammation in the gum using the papillary-marginal-alveolar index (PMA). The hygiene index was evaluated by Quigle-Hein as modified by Tureski.
Results. The hygienic condition of the oral cavity in patients with obstructive sleep apnea was rated as “unsatisfactory”. In the structure of the distribution of periodontal diseases in patients with obstructive sleep apnea, periodontitis of moderate severity prevails, while in the comparison group - periodontitis of mild severity. We also observed a correlation between the severity of apnea and the values of periodontal indices. Index data for mild severity and the data of the comparison group practically did not differ. While in severe apnea, the indices were much higher (average Muhlemann-Cowell index — 1.59±0.3, РМА — 57.49±0.87%) than the comparison group (average Muhlemann-Cowell index — 1.25±0.1, РМА — 38.84±0.93%). When assessing the qualitative composition of the oral microflora by PCR of patients with apnea, a higher number of P. gingivalis and A. Actinomycetemcomitans was revealed compared with the comparison group (p <0.02). Conclusions. According to the results of the dental examination, the prevalence of inflammatory periodontal diseases in patients with obstructive sleep apnea is higher than in the comparison group. The data obtained indicate a more severe periodontal disease in patients with obstructive sleep apnea compared with the comparison group.

Authors: Pryanichnikova NI , Mazhaeva TV
Published: October 2020

Introduction: Physical development is one of the important health criteria of children and adolescents. The
objective of our study was to evaluate anthropometric status indicators of school-aged children and their parents using
the results of a questionnaire-based survey conducted in the Sverdlovsk Region. Materials and methods: The survey was
carried out in accordance with method recommendations and practical guidelines developed by the Federal Research
Center for Nutrition and Biotechnology and involved 3,369 schoolchildren and 5,303 parents. When parents specified
body height and weight of their children in questionnaires, we also made use of the results of regular medical checkups provided by medical workers. Results: We established that the majority children had normal height and weight,
a third of them were overweight, which was more typical for children living in rural areas, and every fifth child was
underweight. Overweight was more prevalent among primary and secondary school boys whereas underweight was
more common among high school girls. The average body mass index of parents was slightly above the healthy weight
range and equaled 25.6 kg/m2
, overweight being more frequent in men. We noticed that most overweight parents of
both genders lived in rural areas. The odds of overweight in children of mothers and fathers with a body mass excess
were 1.9 and 1.4 times higher, respectively. Relative risk values indicate an immediate relationship between overweight in parents, especially mothers, and their children. Conclusions: The risk of childhood overweight and obesity is
higher in children of overweight parents.

The participants were students of International Business of Padjadjaran University taking English for Business Purposes and Speaking for Business Purposes courses. The result of the analysis shows that 100% of students participated in e-learning, and 96.4% have accessibility in online learning. However, only 56% expressed satisfaction with the implementation of e-learning.As a result, the students’ perceptions of e-learning are somewhat fruitful; further, it can promote flexibility, offer personalisation where learners can choose their learning path and pace. Fair assessment of students’ perception in e-learning may grant a good precedent in the implementation of full online learning due to physical isolation caused by the COVID-19 pandemic, which alternatively can be done with the method of blended learning in the New Normal.

Archiwa martwego bliźniego. Żydzi, muzułmanie i dwa ciała wroga
Authors: Biddick Kathleen
Published: October 2020

The article analyses recent works by Giorgio Agamben and Eric Santner, who have interpreted Carl Schmitt’s ideas in the context of left-wing political theology. The article traces how the figure of the undead Muslim recurs in the various philosophers and theologians referred to by these two authors. In this way, it shows how contemporary messianic thinkers unknowingly mourned their ‘dead neighbours’, traumatic irritants from which a messianic pearl was born. In order for this pearl to glow with a miraculous light (as Agamben and Santner would wish it to), modern thinking must engage in an act of neighbour-love, whereby it embraces the untimely, undead excarnations (disembodiments) of a history of typological damage. Otherwise, these traumatised and traumatising neighbours remain undead, driven by critical theories of sovereignty.
Polish Sociology in the Face of Social and Political Changes of the 20th Century
Authors: Kwiatkowski Piotr T. , Weber Jonathan
Published: October 2020

The author of this essay deals with the specif‌icity of sociology in Poland, reaching for the book of Antoni Sułek A Mirror on the High Road. Chapters from the History of Social Research in Poland (2019). Chapters of this book taken as a set constitute a review of the key issues that Polish sociologists strived to tackle in the 20th century. For approximately half of the book (6 chapters) Sułek focuses on issues of Polish sociology from the mid-1950s to the turn of the 1990s: the f‌irst is the change of theoretical and methodological paradigms in Polish sociology in the second half of the 20th century; the second is the successes of Polish sociology, but also its weaknesses — the author devoted much space to the theoretical limitations that prevented sociologists from predicting the formation of Solidarity in 1980. The third topic is the historical analysis of surveys conducted in the last decade of communism — their reliability as well as social and political functions. Finally, Sułek’s vision of socially-involved sociology appears. The strength of such sociology lies in its methodology, with which specific phenomena can be correctly def‌ined, impartially analysed, and systematically investigated. And this in turn enables evidence-based debate and policy.

Published: October 2020

We used a fluorescence lifetime imaging microscopy combined with a microfluidic mixer to study the kinetics of doxorubicin hydrochloride (Dox) diffusion into DNA. The mixing process in the microchannel model was simulated using COMSOL. According to the change of fluorescence lifetime before and after the binding of Dox to DNA, the fluorescence quenching effect of DNA on Dox was obtained both temporally and spatially, and the kinetic information was analyzed from imaging experiments. The experimental results show good agreement with the computational fluid dynamics simulation, and this method could be used to analyze the diffusion process of drug molecules.
