Up-regulated microRNA-33b inhibits epithelial–mesenchymal transition in gallbladder cancer through down-regulating CROCC
Authors: Xu Guohui , Wei Xiaoyong , Tu Qiang , Zhou Cuncai
Published: December 2019

Gallbladder cancer (GBC) is a relatively rare but fatal gastrointestinal tumor. The microRNA-33b (miR-33b), a member of miR-33 family, is reported to function as a tumor suppressor in various cancers. Notably, miR-33 was predicted to target CROCC based on microarray-based analysis. Hereby, we aimed to characterize the effect of miR-33b on epithelial–mesenchymal transition (EMT) in GBC and the potential mechanism involved with the regulation of CROCC. In GBC cell lines, miR-33b expressed at low levels, and CROCC expressed at high levels, with enhanced EMT process. To further examine the specific mechanism of miR-33b and CROCC in GBC, the GBC cells were treated with the miR-33b mimic/inhibitor or siRNA-CROCC to assess the expression alteration of EMT-related genes and cell proliferation, migration, and invasion. MiR-33b was verified to target and down-regulate the expression of CROCC. The miR-33b up-regulation or CROCC silencing was observed to increase the level of E-cadherin but decrease the levels of N-cadherin and Vimentin, corresponding to impeded cell proliferation, migration, invasion, EMT, and tumor growth. The findings suggest that miR-33b up-regulation hinders GBC development through down-regulating CROCC, which was achieved by inhibition of EMT. The present study may provide an insight on a novel target for GBC treatment.
Relationship between the renin–angiotensin–aldosterone system and renal Kir5.1 channels
Authors: Manis Anna D. , Palygin Oleg , Khedr Sherif , Levchenko Vladislav , Hodges Matthew R. , Staruschenko Alexander
Published: December 2019

Kir5.1 (encoded by the Kcnj16 gene) is an inwardly rectifying K+ (Kir) channel highly expressed in the aldosterone-sensitive distal nephron of the kidney, where it forms a functional channel with Kir4.1. Kir4.1/Kir5.1 channels are responsible for setting the transepithelial voltage in the distal nephron and collecting ducts and are thereby major determinants of fluid and electrolyte distribution. These channels contribute to renal blood pressure control and have been implicated in salt-sensitive hypertension. However, mechanisms pertaining to the impact of K ir4.1/Kir5.1-mediated K+ transport on the renin–angiotensin–aldosterone system (RAAS) remain unclear. Herein, we utilized a knockout of Kcnj16 in the Dahl salt-sensitive rat (SSKcnj16-/-) to investigate the relationship between Kir5.1 and RAAS balance and function in the sensitivity of blood pressure to the dietary Na+/K+ ratio. The knockout of Kcnj16 caused substantial elevations in plasma RAAS hormones (aldosterone and angiotensin peptides) and altered the RAAS response to changing the dietary Na+/K+ ratio. Blocking aldosterone with spironolactone caused rapid mortality in SSKcnj16-/- rats. Supplementation of the diet with high K+ was protective against mortality resulting from aldosterone-mediated mechanisms. Captopril and losartan treatment had no effect on the survival of SSKcnj16-/- rats. However, neither of these drugs prevented mortality of SSKcnj16-/- rats when switched to high Na+ diet. These studies revealed that the knockout of Kcnj16 markedly altered RAAS regulation and function, suggesting Kir5.1 as a key regulator of the RAAS, particularly when exposed to changes in dietary sodium and potassium content.
Instability of a DC microgrid with constant power loads caused by modal proximity
Authors: Du Wenjuan , Zheng Kaiyuan , Wang Hai Feng
Published: December 2019

This paper investigates stability of a DC microgrid with integrated constant power loads (CPLs). The investigation is based on an interconnected model of the DC microgrid with two subsystems. One subsystem consists of a CPL under examination and the other subsystem is constituted by remainder of DC microgrid (ROM). Analysis is carried out to indicate when an oscillation mode of CPL subsystem is in the proximity of an oscillation mode of ROM subsystem on complex plane, stability of the DC microgrid decreases as caused by the CPL, leading to growing oscillations in the DC microgrid in the worst case. Hence, the investigation reveals the mechanism about why the CPL may cause instability of DC microgrid from a new perspective of modal proximity. An index is proposed to detect the instability risk by applying the modal analysis to subsystems. The proposed application extends the merit of widely used frequency‐domain analysis to the modal analysis, because instability danger can be detected by the proposed modal analysis in practice without having to establish parametric model of the DC microgrid. Two example DC microgrids with CPLs are presented to demonstrate and evaluate the analysis and conclusions made in the paper.
Midplane temperature and outer edge of the protoplanetary disk around HD 163296

Published: December 2019

Knowledge of the midplane temperature of protoplanetary disks is one of the key ingredients in theories of dust growth and planet formation. However, direct measurement of this quantity is complicated, and often depends on the fitting of complex models to data. In this paper we demonstrate a method to directly measure the midplane gas temperature from an optically thick molecular line if the disk is moderately inclined. The only model assumption that enters is that the line is very optically thick, specifically in the midplane region where we wish to measure the temperature. Freeze-out of the molecule onto dust grains could thwart this. However, in regions that are expected to be warm enough to avoid freeze-out, this method should work. We apply the method to the CO 2–1 line channel maps of the disk around HD 163296. We find that the midplane temperature between 100 and 400 au drops only mildly from 25 K down to 18 K. While we see no direct evidence of the midplane being optically thin due to strong CO depletion by freeze-out, we cannot rule it out either. The fact that the inferred temperatures are close to the expected CO freeze-out temperature could be an indication of this. Incidently, for the disk around HD 163296 we also find dynamic evidence for a rather abrupt outer edge of the disk, suggestive of outside-in photoevaporation or truncation by an unseen companion.

Anthropotechnical technologies for monitoring engineering systems
Authors: Kazaryan Ruben
Published: December 2019

One of the important components of monitoring buildings and structures is an instrumental quantitative assessment of the dynamics of changes in values for all estimated parameters of the technical condition of engineering systems. In the theory of infographics, schematisms (infographic models) are considered intermediate formations of consciousness, mediating sensuality and intellect, whose roots are in the imagination. From an analytical point of view, there is a two-dimensional Euclidean space of phase states, in which the coordinates are “intentions/functions” and “institutions/traditions”, and the “points/phases” are anthropic states (modes, positions, anthroponyms, etc.). The latter can be understood both in the singular sense (human in the singular) and in the collective sense (human as a community, “species being”). In general, this phase space represents the process of “culture-anthropo-psychogenesis” (anthropic synthesis). Determining what to consider the object of study (phase, technique or institution) is a matter of cultural and anthropotechnical functional literacy, and not of evaluation or choice. In addition, everyone must first understand: • Is individual-oriented or grouporiented psychotherapy possible? • What is its “functional equivalent”, as a very important concept of “functional analysis”? • What in the nature of phase anthropic space blocks the appearance of such a “functional equivalent”? • What resists such innovation? • Is “psychotechnical typology” an element of “anthropotechnics”?

Authors: Manzhilevskaya Svetlana , Lihonosov Alexei , Petrenko Lubov
Published: December 2019

Air pollution emissions are released from both natural and anthropogenic sources. During the environment pollution researching and monitoring the special attention should be paid to the construction operations, since during the construction processes many pollutants are released, especially fine dust particles, which are harmful to the health of construction workers and the population living near the construction site. The construction of any object in urban terrain has bad influence not only on the nearby buildings and city infrastructure, but on the existing environment of urban areas. The identification of the important pollution sources that contribute to ambient concentrations of pollutants is essential for developing an effective air quality management plan during building construction. Particular attention should be paid to emissions of fine particles during technological processes of construction with a special degree of dust emission. Control and regulation of the dynamic state of dispersed systems released during technological construction processes using a number of protective measures will reduce emissions of pollutants into the air. The objects of this research were the construction site and residential buildings of a large residential complex «Ekaterininskiy» located in Rostov-on-Don. The obtained measurement data as a result of this type of environmental monitoring showed the level of atmospheric air pollution from the construction industry using the example of the construction of the residential complex “Ekaterininskiy” in Rostov-onDon. After analyzing the situation with dust pollution the protective measures were suggested.

Authors: Kurochkina Valentina
Published: December 2019

The growing race of urbanization and population growth lead to anthropogenic load on the water is increasing all the time. High population density and considerable industrial potential of the urbanized territory are becoming dominant sources of pollution of water bodies. This trend identifies progressive pollution of water bodies and the growing need for sanitary-ecological status of water control facilities. Natural chemical composition and properties of water in surface water bodies are formed depending on the hydrological, soil, climate and other features. Flowinduced suspensions in urban watercourses is one of the main ways of contamination distribution in urbanized areas. For monitoring and reducing the negative impacts on the water quality of watercourses requires estimation of anthropogenic pressures and studying its spatio-temporal variability. Analysis of anthropogenic stress on water objects allows you to set the relationship between the number of coming in the water body of pollutants and concentrations of chemicals in the water. The main aim is to determine the amounts of contaminants accumulated in the river riverbed during the period of the economic utilization of the watercourse and to assess the impact of urbanization on its ecological status. The article deals with the influence of anthropogenous load on river hydraulics and properties of channel sediments that determine the course of channel processes and overall ecological condition of water objects. The interrelation between water body condition, water quality and sediment pollution is presented. Method of estimation of anthropogenous load pollutants in river of urban area sis proposed. Comparative analysis of the load for the rivers of Russia with various water run-off is demonstrated.

Published: December 2019

The goal of our research was to develop methods based on convolutional neural networks for automatically extracting the locations of buildings from high-resolution aerial images. To analyze the quality of developed deep learning algorithms, there was used Sorensen-Dice coefficient of similarity which compares results of algorithms with real masks. These masks were generated automatically from json files and sliced on smaller parts together with respective aerial photos before the training of developed convolutional neural networks. This approach allows us to cope with the problem of segmentation for high-resolution satellite images. All in all we show how deep neural networks implemented and launched on modern GPUs of high-performance supercomputer NVIDIA DGX-1 can be used to efficiently learn and detect needed objects. The problem of building detection on satellite images can be put into practice for urban planning, building control of some municipal objects, search of the best locations for future outlets etc.

Method for constructing estimates of accuracy of measuring equipment based on Bayesian scientific approach
Authors: Khayrullin Rustam
Published: December 2019

Before putting new unique samples of technical systems into commercial operation, as well as before introducing new technologies into production, as a rule, all kinds of tests are carried out. Small and very small volume of statistical data during testing is a characteristic feature of unique and small-scale products and technical systems. Therefore, the problem of constructing effective statistical estimates with a limited amount of statistical information is an important practical problem. The article proposes the development of the Bayesian approach to the construction of point and interval estimates of the parameters of the known distribution laws. The joint use of a priori and posterior information in the processing of statistical data of a limited volume can significantly increase the reliability of the result. As an example, we consider two most typical distribution laws that arise when testing new unique samples of measuring devices and equipment: normal distribution with an unknown average value and a known dispersion, as well as with an unknown average value and an unknown dispersion. It is shown that for these cases, the parameters of the distribution laws themselves are random variables and obey the normal law and gamma normal law. Recalculation formulas are obtained to refine the parameters of these laws, taking into account a posteriori information. If these formulas are applied several times successively, the process of self-learning of the system or self-tuning of the system occurs. Thus, the proposed scientific approach can find application in the development of intelligent self-learning and self-turning systems.

Theory and practice of public hearings in urban planning
Authors: Ivanova Zinaida
Published: December 2019

The author raises the issue of improving the public hearing procedure. The author analyses the established practice of public hearings in Russia, criticizes the new Urban Planning Code adopted in the Russian Federation, and expresses her concerns about the violation of its provisions regulating public hearings and discussions. These concerns are the outcome of an extensive in-depth research into the practice of public hearings, the analysis of their minutes and resolutions; the process of monitoring the course of public hearings, and sociological surveys launched among different categories of respondents in Moscow. The author analyzes the findings of the polls launched among Muscovites, as well as the expert interviews given by the deputies of the Moscow State Duma and members of urban initiative groups. The author’s conclusion is that the conversion of public hearings into an efficient public and political institute requires the reconsideration of their organization and implementation processes, let alone the assignment of a legal status to resolutions of public hearings. The author proposes a two-step public hearing model that will make it possible to expose projects to thorough expert evaluations by independent specialists and to launch extensive discussions among urban residents.

Authors: Scherbakov Alexander , Monastyreva Daria , Smirnov Vitaly
Published: December 2019

Thermocycler processing (TCO) of metals and alloys belongs to one of the most effective ways to obtain the structure of structural steels with a given degree of dispersion. However, the development of thermocycler processing modes in each case is individual in nature and cannot be mechanically transferred from one material to another. Therefore, it is necessary to consider the structural changes in metals during TCO using examples of steels belonging to different groups so that from the whole variety of processes, dissolution and precipitation of phases, stresses and strains, only those that allow you to obtain a given optimal fine-grained structure are selected. Based on the obtained data, we plotted the dependence of the magnetic field strength Hp on the number of cycles during thermal cycling. A comparative analysis of the obtained results is made and conclusions are drawn on the relationship between the magnetic parameter Hp and structural changes in steels during TCO.

Indicator systems are an integral element of the implementation of planned regional development measures, since any program document needs an up-to-date monitoring and evaluation system. The relevance of this research lies in the need to identify the indicators that reflect the priorities and problems of sustainable development of resort areas, and in the need to develop common indicators of sustainability for territories of tourist and recreational purposes. The aim of the study was to analyze existing methods for assessing the sustainability of the development of resort areas, analysis and evaluation of indicators and their impact on sustainable development of the resort area on the example of the Krasnodar region.As a result of the study, we examined custom approaches in assessing sustainable development of resort regions, as well as the methods of the UNWTO and the Government of the Russian Federation (as part of strategic planning). The features of resort areas and the main elements of their development are revealed in the research. It is noted that many indicators are currently being used (most of them of the same type - economic and social) and as a result many aspects of the territorial development remain unexamined. It is proved that in order to ensure the sustainable development of resort areas in the constituent units of the Russian Federation, it is necessary to develop a system of indicators that takes into account existing international experience and the specifics of the economic, social and environmental conditions of the Russian regions.

In recent years in Vietnam, the structure of multi-storey buildings has been strongly developed in both quantity and quality, especially multi-storey buildings made from prefabricated reinforced concrete structures. Collecting documents shows that the Mekong Delta of southern Vietnam has built many multi-storey buildings using prefabricated reinforced concrete frame systems. In the southern climatic conditions, these multi-story buildings are directly affected by climate change, especially the seasonal wind load and the intensity of the wind is getting stronger and more complex, so the the work at the nodes of the frame will be affected. In this study, the authors studied the displacement of the frame system by horizontal displacement, vertical displacement, moment, shear and axial force of the frame according to three models: rigid linked frame, joint linked frame and semi-rigid linked frame.

Two-component model of the concrete composite was considered. The model is considered in two ways. Model “matrix - defects” and model of “matrix-filler”. In the model of “matrix - defects” we made the analysis of the behavior of the model depending on the number and distribution of defects in the body of the concrete prism. It is Described how to change in the number of defects in the process of loading a prismatic concrete specimen and their influence on strength and deformation properties of concrete. We obtained mathematical model of a two-component structure of concrete. We considered the changing deformation model of “matrix-filler” depending on the number and distribution of filler in the body of the concrete prism. Further models have been tested by comparison with computer models and experiments on standard prismatic specimens. It is revealed that the vertical cracks do not affect the vertical deformation of a prism.

The issue is considered in the context of historical, economic, socio-demographic, environmental and sanitary factors. The work justifies that the study of processes of agglomeration development of urban areas makes it possible to predict the prospects of formation of engineering and transport infrastructures, to identify the most effective and balanced solution in the context of sustainable development of urbanized areas.
Using traditions in the architecture of churches in the Orenburg province of Russia
Authors: Ponomarenko Elena
Published: December 2019

The subject of this paper seems to be important due to the everincreasing interest in architectural traditions of Russia’s regions. The purpose of the article is to identify the characteristic features of the architecture of modern wooden temples in the territory of The Orenburg province of the 19th century. The key approach I chose for this study was historical architectural analysis and integration of data from archives and field surveys. A novel systematic analysis of the evolution of church design in the region since ancient times till nowadays is offered. For the first time, a study is made of churches building based on ‘model church design projects for Orenburg the Orenburg defence lines’ and exemplary albums. Descriptions and analyses of the region’s lesser known little known specimen of religious architecture are introduced for the scientific use based on the author’s own in situ investigations. Many archival materials from Russia’s central and regional repositories are considered and published at for the first time. Key properties of modern region Eastern Orthodox churches built in different architecture styles are formulated and classified.

The method of full or partial automation of masonry of stone structures has great prospects. A big hindrance to the development of 3D technology in construction is the need to adapt the concrete mixture to the narrow aperture of the nozzle of the extrusion die. In additive manufacturing, known as 3D printing, properties such as the static and dynamic yield stresses of jointing materials play a main role. The purpose of this article is to define the most optimal concrete mix solution for a printing extruder, which will have the highest rheological indices. In the article was considered the scheme of solution feeding system. The optimum percentage relationship of raw materials included in the watercement solution for further feeding through the nozzle was calculated. The static yield strength of the concrete mixture exceeds 5000 Pa, and the dynamic - above 250 Pa.

The article explores the environmental issues of mankind being a negative consequence of unrestrained scientific and technological progress. Environmental issues have become global because they have reached a level that threatens the possibility of life on Earth. More and more scientists are becoming aware of the need to find new moral and ethical regulations that can change the consumer attitude to nature, help them to realize their responsibility towards it. It suggests the idea of the emergence and formation of a new ethics – the ethics of responsibility. That is, modern moral and ethical principles should not only allow humanity to enjoy all the benefits of scientific and technological civilization, but also to warn against the foreseeable possible threats.
