KiDS+VIKING-450: An internal-consistency test for cosmic shear tomography with a colour-based split of source galaxies
Authors: Li Shun-Sheng , Kuijken Konrad , Hoekstra Henk , Hildebrandt Hendrik , Joachimi Benjamin , Kannawadi Arun
Published: December 2020

We performed an internal-consistency test of the KiDS+VIKING-450 (KV450) cosmic shear analysis with a colour-based split of source galaxies. Utilising the same measurements and calibrations for both sub-samples, we inspected the characteristics of the shear measurements and the performance of the calibration pipelines. On the modelling side, we examined the observational nuisance parameters, specifically those for the redshift calibration and intrinsic alignments, using a Bayesian analysis with dedicated test parameters. We verified that the current nuisance parameters are sufficient for the KV450 data to capture residual systematics, with slight deviations seen in the second and the third redshift tomographic bins. Our test also showcases the degeneracy between the inferred amplitude of intrinsic alignments and the redshift uncertainties in low redshift tomographic bins. The test is rather insensitive to the background cosmology and, therefore, can be implemented before any cosmological inference is made.
Method for the fuzzy control system synthesis for the analytical approximation characteristics of the typical nonlinear elements characteristics
Authors: Lubentsov V , Shakhrai E , Lubentsova E
Published: December 2020

The solution of the problem concerning the control system synthesis with a fuzzy controller on the basis of typical nonlinear analytical approximation characteristics with continuous differentiable functions like sigmoid type has been considered. A method of synthesis which is based on the fact that the rulebase and membership function are formed by the way of comparing the control or corrective impacts of the fuzzy controller (prototype) or a controller with approximating control (CAC) has been suggested for problem solving. For the CAC construction the closest coincidence of graphically installed controllers’ impacts are taken. This makes it possible to exclude subjective errors connecting with a possible non-representative ruleset for the rulebase forming. The result of the work is to obtain a new class of controllers based on the approximating continuous functions, which are simpler for constructing multi-mode control systems. The practical significance lies in the fact, that the tuning of the fuzzy controller based on the analytical continuous approximation of the typical nonlinear elements’ characteristics comes down to two basic parameters: the coefficient that determines the curvature (slope) of the characteristic in the transit mode and the parameter that determines the control impact value in the static mode. The advantage of this smooth characteristic in relation to the piecewise linear approximation is that there is no need to determine the moments (points) of switching nonlinear characteristics during the system operation.
Model of the synchronization network functioning process in the context of intellectualization of network control functions
Authors: Kanaev A.K. , Oparin E.V. , Oparina E.V.
Published: December 2020

This paper provides a simulation model of the synchronization network (SN) functioning process, which is distinguished by the completeness of accounting for the functioning states. The key indicator of the synchronization network functioning process is the duration of the SN control cycle, which is understood as the time from the moment a failure occurs on the synchronization network until the moment the synchronization signal transmission mode is restored. On the basis of the developed simulation model of the synchronization network functioning process, the duration of the SN control cycle is estimated depending on the time spent in individual states of the SN functioning process and on the characteristics of individual subsystems of the synchronization system. The results obtained can serve as a basis for developing sound strategies and plans for controlling the synchronization network.

Published: December 2020

An airborne technical vision system of a modern aircraft is, on the one hand, a complex of multispectral sensors and, on the other, airborne computer equipment. The onboard computer solves a wide range of complex digital image processing tasks. The strict requirements are imposed on the computer mathematical software on the image processing time and on the quality of the result displayed on the pilot screen. The software development for such a complex system involves mathematical modelling and use modern information technologies in process of computational algorithms development for task solving. The proposed work discusses ways of solving subtasks of one of the most important subsystems of the airborne complex - the image fusion subsystem and solving the inverse navigation problem. The subsystem is represented by two blocks of tasks: tasks of primary image processing and high-level tasks. The primary processing unit solves the problems of image noise suppression, image enhancement, image fusion and edge detection. In the high-level block of tasks, the tasks of key points detection on real and virtual images, the tasks of a geometric transformation estimation of one image to the plane of another, and the task of a 3D model construction of the underlying surface are solved. The paper presents the results of mathematical modelling in the process of algorithms development for above problems solving. The new results of mathematical modelling of the noise estimation problem are presented in detail. The description of methods and results of other problems solving is less detailed due to article limit but provided with links to the corresponding publications of the authors.

Authors: Bogachev V.A. , Kravets A.S. , Bogachev T.V.
Published: December 2020

A multi-agent approach has been developed to find the optimal distribution of freight traffic on the considered railway loop for multimodal transportation carried out within the framework of an oligopolistic market. At the first stage of research, the method of economic-geographical delimitation of the «influence areas» of loading stations, developed earlier by the authors, is applied. The obtained territorial picture of the rational distribution of traffic flows is used further when introducing restrictions in a multi-criteria optimization problem, which is solved as an integer programming problem in the environment of the system of analytical calculations. As a result, on the basis of an assessment of the transport and technological infrastructure of the loop and the cost of transport services, a mathematical model is built that allows to optimize the process of freight transportation.
Modelling the generation of dusty marine aerosol by expeditionary data and remote sensing methods over the Black Sea region
Authors: Papkova A , Papkov S , Shukalo D
Published: December 2020

During a long-range transport, Sahara dust is naturally mixed with other aerosols, including maritime. At present, the mixing of these types of marine and dust aerosols is of particular interest, since it is important to correctly estimate the ionic and mass balance of aerosol particles. This problem is caused by the need for a reliable determination of the aerosol source and for correct atmospheric correction of satellite data. An analysis was made of the correlation between the change in the AOT parameter and the dates of dust transport from the Sahara to the Black Sea region. The analysis results confirmed the fact that the presence of dust aerosol over the Black Sea water area has a strong effect on the AOT indicator at all wavelengths, increasing the parameter almost by 2 times. This fact is correspondent to the generation of a secondary type of aerosol, namely, dusty marine aerosol. Analysis of CALIPSO aerosol subtype maps also revealed the presence of dusty marine aerosol with corresponding depolarization coefficients.

Published: December 2020

At the present stage, in the context of global economic and political problems, the educational space in countries with a small open economy is of particular importance, since it is recognized as one of the key elements of ensuring public welfare. In addition to the costs directly allocated to education in Georgia, the government finances various retraining courses, the need for which is due to the higher education programs which seem to be incompatible with the labour market. The purpose of this article is to determine the cost efficiency of retraining incurred by the state, and the reasons for these additional costs as well as the aspects of retraining (profession / qualification) provided to higher education diploma holders. This last group is of particular interest to us to determine what causes the need for services provided by the employment agency in the case of people with higher education which, possibly, leads us to gaps in study programs, which, in turn, can be caused by a) higher education programs, which cannot give graduates the proper skills; or/and b) the institution of higher education has not studied the required number of graduates/skills needed in the market (and determines the number of students according to its academic staff) and/or graduates with low academic performance (which are supported by the institution of higher education so as not to lose a voucher) need retraining.

Authors: Vorobyeva I V
Published: December 2020

The leading place in the structure of blindness and low vision is occupied by two diseases: primary open-angle glaucoma and diabetic retinopathy. The combination of two diseases in one eye gives an even more severe prognosis for vision. Modern diagnostic equipment helps in accurate and early diagnosis of the disease by analyzing digital data of the optic nerve head and macular area of the retina according to the results of an optical coherence tomograph. A mathematical model for predicting the development of diabetic retinopathy and primary open-angle glaucoma according to the proposed mathematical criteria has been developed. The criteria represent the ratio of the integral area of the neuroretinal rim to the integral volume of the neuroretinal rim; the retinal thickness criterion and criterion of the primary open-angle glaucoma and diabetic retinopathy are calculated. A computer program has been developed. The algorithm of the program, which includes windows for entering digital data of the macular zone and parameters of the optic nerve head, is presented. The result of the program is the statement of the risk of developing combined pathology of the fundus in a particular patient.

Published: December 2020

Currently, the main priorities in agricultural production are ecologization, rational use of natural resources, resource-conservation and economic practicability. Therefore, biotechnologies for growing agricultural crop develop. The article presents the results of effectiveness of pre-sowing treatment with polyfunctional microbial preparations compared to the use of mineral fertilizer Ammophos in growing Cіcer arіetіnum L. in the steppe zone of the Crimea on non-irrigated southern Chernozem in 2015-2017. Weather conditions during the growing season and treatment with microbial preparations, as well as the use of mineral fertilizers, affected seed productivity of chickpeas in the time of research. On average, for three years, bacterization with Rhizobofit, Cyano-rhizobial consortium and complex Rhizobofit + Phosfoenterin + Biopolicyd significantly increased 1000 seeds weight and seed yield by 16.67 g (6.7%) and 0.15 t/ha (10.8%); 27.27 g (9.8%) and 0.1 t/ha (7.2%); 14.14 g (5.5%) and 0.22 n/ha (15.1%), respectively, compared to the Ammophos application in dose N30P30 (Duncan’s test p < 0,000121). These preparations are recommended for biologised agrotechnology for growing chickpea in the steppe zone of the Crimea and obtaining ecologically safe production.

Authors: Turina E L , Prakhova T Ya
Published: December 2020

The purpose of the research is to assess the productivity and adaptability of Camelina sativa depending on the natural and climatic conditions of the forest-steppe zone of the Middle Volga region and the steppe Crimea. The researches were conducted in two regions (Penza and Crimea) with contrasting hydrothermal conditions in 2015–2019 years. Climate conditions in the years of researches were characterized by significant variability in both the degree of humidity and temperature regime in both regions. The hydrothermal coefficient in the Crimea varied in the range of 0.23–1.11, in the conditions of Penza - from 0.45 to 1.10. The index of environmental conditions varied from -0.58 to 1.28 units depending on the natural and climatic zone. On average, in 2015–2019, the productivity of Camelina changed from 1.45 to 1.79 t/ha in Penza and from 0.56 to 1.66 t/ha in Crimea. The highest yield of Camelina sativa was recorded in 2016 in Penza and in 2017 in the Crimea and amounted to 1.79 and 1.66 t/ha, respectively. The value of the index of environmental conditions is 1.17 and 1.28 with hydrothermal coefficient of 0.82 and 0.61, respectively. Depending on the conditions of the year and the region, the oil content varied from 33.9 to 43.9 %. At the same time, there is a tendency to decrease the amount of oil for all years of study in the direction from the Crimea to the zone of the Penza region. Camelina sativa is characterized by a high level of resistance to stressful conditions (0.49– 1.10), differs in environmental adaptability (bi=1.15–1.17), has a high fitness criterion, 41.2–41.5 g/m2, depending on the region.

Published: December 2020

The main problems of the nature and management of agricultural land under the conditions of modern soil management have been considered. Among the processes which cause soil structure decline on the Crimean peninsula, predominate: erosion, deflation, dehumification, secondary salinization and alkalinization of previously irrigated areas, overgrowing of agricultural land with shrubs and light forests, and some other processes leading to loss of soil fertility. Considerable attention has been paid to the problem of developing a system for soil resources monitoring. It has been noted that the main problems in the rational management of agricultural land in the region are: the imperfection of the regional monitoring system for the nature, conservation, management and protection of soil cover, and the lack of reliable and complete information on the nature of agricultural land.

Authors: Ambros E , Trofimova E , Novikova T
Published: December 2020

For the first time, the effect mechanocomposite based on biogenic silica and green tea flavonoids (MC) on reduction of oxidative stress in microshoots of strawberry plantlets (cv. “Solnechnaya polyanka”) during in vitro multiplication, shoot elongation and rooting stages were established. Compared with the plantlets cultured in MC-free media, the ones cultured in media supplemented with MC showed increased key antioxidant enzyme activities (superoxide dismutase – SOD, peroxidase – POD, catalase – CAT). SOD activity increased from 1.1 to 1.4 times at 2.5 and 5.0 mg L-1 MC, POD activity – from 1.8 to 3.8 times at 5.0 and 10.0 mg L-1 MC, and CAT activity – from 1.1 to 1.4 times at 5.0 mg L-1 MC depending on the stage of micropropagation. The high antioxidant enzyme activities correlated with the decrease of H2O2 content (up to 1.7 times compared with the control). The revealed changes in the physiological status of strawberry plantlets in the presence of MC contribute to the further successful acclimatization of regenerants to ex vitro conditions. Thus, these results have demonstrated the potential of “green chemistry” for the production of healthy plant material of strawberry cultivars.

The varieties were grown in the valley agrolandscape zone of Krasnodar region (Russia) in 2017–2019. The studied rice varieties are included in the State Register of Protected Breeding Achievements. The grain size by weight of 1000 absolutely dry grains (weight of 1000 a.d.g.) was determined according to GOST 10842-89, fracturing on a DSZ-3 diaphanoscope, protein content was measured using an Infralum FT-10 device. The determination of amylose was carried out colorimetrically using the amylose-iodine reaction according to Juliano. The varieties have a medium-sized caryopsis (21.5-27.0 g of 1000 grains); of them, the variety Yuzhnaya noch is characterized by the smallest grain. The variety Mars belongs to the low amylose group, varieties Mavr, Rubin and Gagat to the medium amylose group, Yuzhnaya noch to the waxy group. In terms of protein content in grain, all varieties are classified as medium protein. The maximum grain fracture was in variety Mavr in the range of 19-25% and the minimum in Mars and Gagat, respectively 2-5 and 2-6%. Variations in grain size indicators, amylose and protein content of varieties are weak in all varieties of special purpose, which testified to their high stability under growing conditions.

The study is devoted to the development of approach to comprehensive assessment of the regional agro-food industry development problems. This task was solved using the methods of expert assessment and statistical analysis of their results. We have substantiated a system of agro-food industry development indicators, which covers the level of enterprises and the level of government. Approbation of the proposed approach using the example of the Republic of Crimea revealed the key problems. At the enterprise level: low level of development of advanced technologies, low share of innovative products, ineffective organization of cause-and-effect analysis, insufficient scientific feasibility of technological processes. At the state level: insufficiently effective state regulation in the field of import substitution, insufficient stimulation of demand for domestic products of the processing industry of the agro-industrial complex (AIC), insufficient state stimulation of the production of highquality domestic products, insufficient level of scientific research support. This allows determining the priority directions for the development of recommendations and the implementation of actions to ensure the regional agro-food industry development.

Published: December 2020

The existing approaches to the interaction of business structures and government bodies have been investigated. The factors influencing the formation of the interaction process and the achievement of a balance between the interests of government and business have been determined. A matrix of interaction models is proposed based on the ratio of the strength of the state and the level of integration of business structures, as well as the degree of involvement of subjects in the interaction process. The corporatist model of interaction is defined as widespread in Russia, within the framework of which the factors that worsen the relationship between power and business structures in the Russian Federation have been identified as follows: lobbyism and corruption. It is shown that in modern Russian economic realities, the partnership model is more in line with the tasks of effective interaction between the state and business. The trends in the development of models of interaction between the state and business in Russia and the feasibility of transition to a network partnership model based on breakthrough development in a strategic perspective have been determined. The advantages of the transition to the specified model of interaction between the state and business are have been substantiated, which make it possible to achieve a breakthrough in the digitalization of the real sector and the active introduction of domestic innovative developments, the formation of a special innovative culture, which involves the activation and inclusion of an individual as a full-fledged participant in the innovation process and the growth of entrepreneurial activity of broad strata of the Russian population.
Assessing the Stakeholders’ Contribution to Business Value
Authors: Patrusheva Elena , Sapir Elena , Karachev Igor
Published: December 2020

Stakeholder theory is the most attractive fundamental concept to ensure the necessary improvement of corporate governance in the modern world, integrated into the idea of value maximization as the main strategic goal of the enterprise. The proposed concept of total value considers this category as the sum of the organizational wealth and the values of the stakeholders, which together constitute the total contribution of the economic system to public welfare. Recognizing not only the financial implications of stakeholder relationships, the authors propose practical tools for value management, based on the agreed interaction of stakeholders – the modeling of resource flows to optimize the resulting total value and the algorithm of step-by-step management of interaction with stakeholders. The modeling of value creation reflects both the organizational benefits of interaction and explicitly identifies the value of the stakeholders’ benefits, and also discloses a list of key management factors: the economic value of the resources used by parties, the fairness of the exchange, the relationship between interacting companies, the opportunity costs, etc. Critical aspects of value creation that go beyond profitability and economic returns are highlighted. Corporate values can only be understood by reference to the multiplicity of stakeholders’ value perspectives.It is recommended that the process of managing interaction with stakeholders should be guided by an extensive interpretation of the target (value) setting of the business, taking into account the totality of material and intangible resource flows between the parties.
Searching for mechanism of correlation of interests of the transport holding’s managers and employees

Published: December 2020

Digital transformation is the current development paradigm of any modern organisation. Digitalisation, automation and robotisation actively affect the activities of both large and small enterprises and have an impact on all spheres of life. Studying the correlation of corporate interests of employees and managers of Russian Railways, JSC transport holding allowed us to identify areas of their correlation, as well as areas where we defined their inconsistency. At the same time, this area of interaction between employees and employers requires active research since it does not always fall into the research field. Based on empirical research, analysis of corporate reports on the company’s business activities, as well as content analysis of interviews with managers, the authors show that alignment of interest can be achieved by means of systematic development and meeting the needs of staff in training and development; availability of a clear program of the company’s development and provision of a wide range of social benefits and guarantees contribute to the achievement of stable position on the market of logistic services, stable work teams, high level of staff involvement in the activities of the company, higher job satisfaction, greater confidence of staff in developing and implementing changes, as well as improving technical, technological and operating processes. On the other hand, the study shows that in the opinion of managers and potential employees (based on the analysis of the generation Z’s system of values) the corporate management model of Russian Railways, JSC may create barriers to the development of the company and fulfilment of employees’ labour potential. This problem can be avoided by improving corporate management systems and increasing the independence of the staff.

Since the work on Joseph Schumpeter’s entrepreneurial theory in the process of creative destruction, many works have been devoted to innovation. However, this previous work often approached innovation from an organizational point of view with a technical orientation. But today innovation covers all sectors of economic activity or not. In addition, we can see that this research on innovation has been more active and implemented in developed countries. On the other hand, some work; have been done in developing country, which shows a low level of innovation development. Therefore, to fill the gap in African literature, the purpose of this article is timely to develop a model of innovation policy for low-income countries in general, and for West and North African countries in particular. To achieve this goal, it is necessary to make the diagnosis at the level of African countries in terms of innovation, in order to solve problems related to the challenges of innovation on this continent. Finally, relevant recommendations ranging from the meaning of an effective implementation of the proposed innovation policy through a mechanism and a verification algorithm for a positive economic and social impact.

Published: December 2020

Der Lungenultraschall bietet eine rasche und zuverlässige Diagnostik zum Ausschluss eines Pneumothorax. Im vorliegenden Artikel wird der Untersuchungsablauf einer Lungenultraschalluntersuchung in der Neonatologie beschrieben. In diesem Zusammenhang ist das Verständnis und die Deutung wichtiger Artefakte und Muster, wie dem Pleuragleiten, A- und B-Linien sowie dem Lungenpunkt essenziell. Mithilfe dieser Untersuchungsbefunde lassen sich Rule-in- und Rule-out-Kriterien in der Pneumothoraxdiagnostik beschreiben. Der Lungenultraschall kann somit einen Beitrag zur Strahlenreduktion in der Neonatologie leisten.

This study investigated the effects of marine phytoplankton supplementation on 1) perceived recovery and ground reaction forces in humans following a non-functional overreaching resistance-training program and 2) myogenic molecular markers associated with muscle cell recovery in a rat model. In the human trial, a 5-week resistance-training program with intentional overreaching on weeks 2 and 5 was implemented. Results indicate that marine phytoplankton prompted positive changes in perceived recovery at post-testing and, while both marine phytoplankton and placebo conditions demonstrated decreased peak and mean rate of force development following the overreaching weeks, placebo remained decreased at post-testing while marine phytoplankton returned to baseline levels. In the rat model, rats were divided into four conditions: (i) control, (ii) exercise, (iii) exercise + marine phytoplankton 2.55 mg·d-1, or (iv) exercise+marine phytoplankton 5.1 mg·d-1. Rats in exercising conditions performed treadmill exercise 5 d·wk-1 for 6 weeks. Marine phytoplankton in exercising rats increased positive and decrease negative myogenic factors regulating satellite cell proliferation. Taken together, marine phytoplankton improved perceptual and functional indices of exercise recovery in an overreaching human model and, mechanistically, this could be driven through cell cycle regulation and a potential to improve protein turnover.

The new concept of thrombosis associated with an inflammatory process is called thromboinflammation. Indeed, both thrombosis and inflammation interplay one with the other in a feed forward manner amplifying the whole process. This pathological reaction in response to a wide variety of sterile or non-sterile stimuli eventually causes acute organ damage. In this context, neutrophils, mainly involved in eliminating pathogens as an early barrier to infection, form neutrophil extracellular traps (NETs) that are antimicrobial structures responsible of deleterious side effects such as thrombotic complications. Although NETosis mechanisms are being unraveled, there are still many regulatory elements that have to be discovered. Micro-ribonucleic acids (miRNAs) are important modulators of gene expression implicated in human pathophysiology almost two decades ago. Among the different miRNAs implicated in inflammation, miR-146a is of special interest because: (1) it regulates among others, Toll-like receptors/nuclear factor-κB axis which is of paramount importance in inflammatory processes, (2) it regulates the formation of NETs by modifying their aging phenotype, and (3) it has expression levels that may decrease among individuals up to 50%, controlled in part by the presence of several polymorphisms. In this article, we will review the main characteristics of miR-146a biology. In addition, we will detail how miR-146a is implicated in the development of two paradigmatic diseases in which thrombosis and inflammation interact, cardiovascular diseases and sepsis, and their association with the presence of miR-146a polymorphisms and the use of miR-146a as a marker of cardiovascular diseases and sepsis.

Published: December 2020

Endovascular graft infection is a rare but challenging complication that requires a tailored approach to remove the infected graft and restore the arterial circulation combined with long-term antibiotic therapy. We present a case surgically treated with explant of the graft and reconstruction of the thoracoabdominal aorta. Microbiological investigation revealed growth of Neisseria meningitidis, which is extremely rare in this location, and to our knowledge, has not been previously published in the literature.

Pur-α protein (PURA) syndrome manifests in early childhood with core features such as neurodevelopmental and speech delay, feeding difficulties, epilepsy, and hypotonia at birth. We identified three cases with PURA syndrome in a cohort of patients with unexplained muscular weakness, presenting with a predominantly neuromuscular and ataxic phenotype. We further characterize the clinical presentation of PURA syndrome including myopathic facies and muscular weakness as the main clinical symptoms in combination with elevated serum creatine kinase levels. Furthermore, we report two novel variants located in the conservative domains PUR-I and PUR-II. For the first time, we present the muscle biopsies of PURA syndrome patients, showing myopathic changes, fiber size variability, and fast fiber atrophy as the key features. PURA syndrome should be taken into consideration as a differential diagnosis in pediatric patients with unexplained muscle weakness.
