Endothelin receptor antagonism improves glucose handling, dyslipidemia, and adipose tissue inflammation in obese mice
Authors: Rivera-Gonzalez Osvaldo , Wilson Natalie A. , Coats Laura E. , Taylor Erin B. , Speed Joshua S.
Published: July 2021

Endothelin-1 (ET-1) is elevated in patients with obesity; however, its contribution to the pathophysiology related to obesity is not fully understood. We hypothesized that high ET-1 levels cause dyslipidemia, inflammation, and insulin resistance within the adipose tissue of obese mice. To test this hypothesis, male C57BL/6J mice were fed either normal diet (NMD) or high-fat diet (HFD) for 8 weeks followed by 2 weeks of treatment with either vehicle, atrasentan (ETA receptor antagonist, 10 mg/kg/day) or bosentan (ETA/ETB receptor antagonist, 100 mg/kg/day). Atrasentan and bosentan lowered circulating non-esterified free fatty acids and triglycerides seen in HFD mice, while atrasentan-treated mice had significantly lower liver triglycerides compared with non-treated HFD mice. ET-1 receptor blockade significantly improved insulin tolerance compared with insulin-resistant HFD mice and lowered expression of genes in epididymal white adipose tissue (eWAT) associated with insulin resistance and inflammation. Flow cytometric analyses of eWAT indicated that HFD mice had significantly higher percentages of both CD4+ and CD8+ T cells compared with NMD mice, which was attenuated by treatment with atrasentan or bosentan. Atrasentan treatment also abolished the decrease in eosinophils seen in HFD mice. Taken together, these data indicate that ETA and ETA/ETB receptor blockade improves peripheral glucose homeostasis, dyslipidemia and liver triglycerides, and also attenuates the pro-inflammatory immune profile in eWAT of mice fed HFD. These data suggest a potential use for ETA and ETA/ETB receptor blockers in the treatment of obesity-associated dyslipidemia and insulin resistance.
Reservoir inflow predicting model based on machine learning algorithm via multi‐model fusion: A case study of Jinshuitan river basin
Authors: Zhang Wei , Wang Hanyong , Lin Yemin , Jin Jianle , Liu Wenjuan , An Xiaolan
Published: July 2021

Flood prevention and disaster mitigation have a great impact on people's lives and properties, and so it is urgent to realise high‐accuracy inflow predictions for flood early warning. To this end, a prediction model based on a machine learning algorithm via a multimodel combination method is proposed to predict the inflow of Jinshuitan reservoir. Firstly, a data formatting scheme called the ’hydrological regime profile‘ is designed for input data. The whole data set is partitioned into a low‐flow subset and a high‐flow subset. Considering the high dimensions of the complex input data, convolutional neural networks (CNN), EXtreme gradient Boosting model (XGBoost) and a partial least squares model (PLS) are used. In the CNN and XGBoost models, a special loss function weighted on inflow is designed to improve the performance on high‐inflow predictions. Finally, a multi‐model combination method is proposed to improve the prediction performance. Compared with XGBoost, CNN and PLS, the root mean square error of the combined model is reduced by 41.64%, 72.29% and 3.41%, respectively. As a consequence, the combined model is able to predict the inflows with higher accuracy compared to the single models.
Optimization of high breakdown voltage vertical trapezoidal GaN p‐n diode with a high‐K/low‐K compound dielectric for power applications
Authors: Du Jiangfeng , Zhao Zhiyuan , Tian Kuiyuan , Liu Yong , Jiang Yonggang , Yu Qi
Published: July 2021

This paper proposes a vertical trapezoidal GaN p‐n diode with a high‐K/low‐K compound dielectric (CD‐TGD) to improve the breakdown voltage (BV). By introducing the compound dielectric structure, a new peak of electric field will be induced in the n‐type GaN drift region of the trapezoidal diode, to make the electric field distribution in the drift‐region more uniform. The key parameters of the CD‐TGD, including the angle of the bevel structure, the doping concentration of drift region, and the size of high‐K/low‐K compound dielectric layers, have been comprehensively investigated by TCAD Silvaco simulation to reveal their impacts on the diode's properties. The breakdown voltage of the optimized structure is boosted from 2780 V for vertical GaN diodes (VGD) to 4360 V for CD‐TGD, which is 56.8% higher than that of VGD. The on‐state resistance of the optimized CD‐TGD is 1.53 mΩ·cm2, yielding a high FOM of 12.4 GW/cm2. What is more, the average breakdown electric field is 2.73 MV/cm, which is much closer to the material limits of GaN.
The first heavy-metal hot subdwarf composite binary SB 744
Authors: Németh P. , Vos J. , Molina F. , Bastian A.
Published: July 2021

Aims. The long-period sdOB+G1V type spectroscopic binary SB 744 reveals strong lines of fluorine and lead in the optical spectrum of the sdOB star and subsolar metallicity in the G1V companion thanks to a radial velocity follow-up study. Using high-quality observations and Gaia astrometric data, we aim to measure the chemical composition and Galactic kinematics of the system to put it into context with known populations of hot subdwarfs. Such binary systems have great potential to provide insights into the late stages of binary evolution as well as into the mysterious formation of stripped-core helium-burning stars.

Methods. We analyzed the optical spectra with homogeneous atmospheric models to derive the surface parameters of the binary members from a direct wavelength space decomposition. Then, we independently measured the atmospheric properties of the cool companion. The two independent methods achieved consistent results, which were amended with constraints from spectral energy distributions to provide a subdwarf mass. In addition, Gaia astrometry allowed us to derive the Galactic kinematics of the system.

Results. SB 744 turned out to be an old, Population II system that has gone through dramatic events. The hot subdwarf star belongs to the heavy-metal subclass of sdOB stars and we report super-solar abundances of lead, based on Pb III/IV lines. The He abundance of the hot subdwarf is the lowest among the known heavy-metal sdOB stars. The presence of fluorine implies that SB 744 was once a hierarchical triple system and the inner binary has merged in the near past. As an alternative scenario, single-star evolution through late core helium flash and atmospheric mixing can also produce the observed fluorine abundances. The atmospheric metal overabundances that are currently observed may perhaps be the result of a combination of mixing processes during formation and radiative support.
Quelle place du conseil agricole dans les services support à l’innovation à Madagascar ?

Le conseil agricole occupe une place prépondérante dans l’appui aux processus d’innovation, particulièrement dans les pays du Sud. Or, l’accompagnement de l’innovation nécessite une diversité de formes d’appuis, appelés services support à l’innovation (SSI). À partir d’une analyse exploratoire à Madagascar, cet article questionne la place du conseil agricole vis-à-vis de la diversité des organisations et des activités d’accompagnement de l’innovation. Les principales organisations fournissant des SSI ont été étudiées dans quatre régions des Hautes Terres de Madagascar et leur offre de SSI caractérisée. Les résultats montrent que le conseil technique reste prépondérant dans l’éventail de l’offre de SSI, avec un fort pluralisme des fournisseurs de conseil et une diversité de combinaisons avec les autres SSI. Or, les porteurs d’innovation doivent bénéficier d’autres SSI, tels que le renforcement de capacité, la mise en réseau, des appuis institutionnels, un accès au financement, intrants et équipements nécessaires à l’innovation. Ces résultats appellent à renouveler les postures du conseiller agricole vers davantage d’appui au renforcement de capacité et interrogent la stratégie des organisations vis-à-vis de leur appui à l’innovation : la spécialisation dans le conseil, la combinaison à d’autres SSI ou la collaboration avec d’autres organisations. Ces éléments renouvellent le constat du pluralisme de l’offre de conseil qui, analysé par le prisme des SSI, ne s’applique pas seulement à l’échelon de l’agent-conseiller ou de l’organisation, mais également dans des réseaux d’organisations aux configurations variables. Les perspectives de cette analyse sont d’assurer la coordination des dispositifs de conseil avec les autres fournisseurs de SSI pour une plus grande efficacité dans l’accompagnement des porteurs d’innovation.
Possible impact of the green economy requirements on the furniture industry development in Kaliningrad region
Authors: Safonova Irina , Golubev Andrei
Published: July 2021

The article discusses the possible impact of the requirements of the “green economy” on the furniture industry development in Kaliningrad region. The main question posed in the article – whether furniture manufacturers from Kaliningrad region can withstand future changes related to the “green economy”. The authors collected and examined data on the main factors affecting the Kaliningrad furniture industry earlier (changes in customs regulations) and now (impact of the COVID-19 pandemic). Along with the general analysis, the authors considered the manufacture of individual products. No sharper drop in the furniture manufacture for home use compared with the furniture manufacture for offices was found as a result. As vendors, component suppliers, and furniture manufacturers have formed a regional cluster, its role in overcoming current challenges was also examined. Taking into account the current situation, the authors come to a rather negative conclusion about the contribution of the Kaliningrad Association of Furniture Manufacturers to the general anti-crisis actions. The requirements of the “green economy” are expected to lead to a significant increase in capital expenditures for Kaliningrad furniture manufacturers. Taking into account the current problems caused by changes in customs regulations and the COVID-19 epidemic, Kaliningrad furniture manufacturers will not put these costs at the top of their priorities in the next 3-5 years.
Background for forming a unified methodological approach to risk assessment of new transport construction projects
Authors: Solskaya Irina , Khaletskaya Svetlana , Rabushenko Oksana , Golovan Sofia
Published: July 2021

In the most general case, the assessment of the risks of investment projects is carried out on the basis of a single standard methodological approach, sufficiently adapted to a large number of industry structures. However, new projects implemented in order to expand and radically modify the infrastructure of railway transport in the Russian Federation require clarification of the principles and provisions of existing approaches for their reasonable implementation. The reason for this lies in the sectoral features of the projects: the return on investment is longer than in other sectors; the social importance of new infrastructure facilities; attraction of budgetary resources to finance new transport construction projects. The article discusses the main prerequisites for the formation of a methodological approach to the analysis and assessment of the risks of construction of infrastructure facilities of railway transport. The author's approach to assessing the risks of projects for the construction of infrastructure facilities is proposed from the standpoint of their relationship with the characteristics of project stakeholders, which determines the directions of risk analysis at the current stage of project implementation and the consequences of the previous stages.

Sustainable functioning of the passenger transport logistics system
Authors: Protasova Liudmila , Zueva Olga
Published: July 2021

The sustainable development of the transport logistics system (TLS) of passenger transportation in Russia is of great social importance for the mobility of the population. The purpose of the study is to check whether the course of the company JSC “FPC” for sustainable development, formulated in the strategy until 2030, is being implemented. The company has created a corporate quality system to improve the quality of services, ensure customer-oriented processes, and improve traffic safety. However, statistics show that the company’s development is unstable, as the share of passenger traffic is small – 6,6% in 2012 and 5,5 % in 2019, and the volume decreased from 1421 to 1201 million people during this period. The majority of the population of the country chooses other modes of transport, because their need for mobility is not provided: the prices of railway tickets are high; also the travel time is significant, due to the low speeds of passenger trains. And the quality of the infrastructure (the state of the railway track and tracks) currently does not allow organizing high-speed movement of modern transport on the territory of the country; serious investments are needed to solve this problem.

Authors: Baklanov P.Ya.
Published: July 2021

Sustainable development of a region is considered as stable development, balanced in the economic, social and environmental areas. To achieve sustainable development of a coastal region, it is necessary to cover the entire integral geosystem, including land territory of the region and the adjacent sea area. It is necessary to model dynamics of the geosystem using various information and geographic information systems. On this basis, strategic planning and monitoring of the sustainable development should be employed. Basic core principle for the sustainable development of coastal regions is a regional nature management, including usage of the natural resources of land, sea and ocean. At the same time, it is necessary to identify and evaluate aqua-territorial combinations of the natural resources and inter-resource ties. There are some problems and limitations of the sustainable development of coastal regions, which are highlighted, including dangerous processes and phenomena (wave, tsunami, typhoons, etc.), the need for coastal protection, etc., as well as favorable factors - availability of various marine natural resources, possibility of using sea transport and availability of sea markets, etc.

Legal regulation of “green” agriculture in Russia: current state and prospects of development
Authors: Voronina Natalia , Shnorr Zhanna
Published: July 2021

According to the Millennium Development Goals, approved by the UN in 2000, it is necessary to eradicate hunger in the 21st century, while solving the environmental problems that have accumulated over the past hundred years. The international community sees a way out in the development of a “green” economy, an integral part of which is agriculture. The current state of technology development enables the use of innovative methods of agricultural activities, including biotechnology. However, the consequences of their use for humans and the environment are completely unknown. Biotechnologies make it possible to obtain agricultural products with pre-defined characteristics, adapt their cultivation and production to unfavorable natural conditions, and increase labor productivity. But at the same time, the UN and FAO strategic planning documents note that produced agricultural products shall be safe for human health, and agricultural activities shall have a minimal impact on the environment. Therefore, the need for the formation and development of a model of “green” agriculture is justified at the international level. In Russia, attention is also paid to the production of products that are as safe as possible for both humans and the environment. At the same time, the current state of legal regulation of “green” agriculture does not allow us to speak about the formed effective model of legal regulation of the production of environmentally safe agricultural products. Legal problems and conflicts of the current legislation do not allow our country to take a competitive position in the international market of agricultural products. The purpose of this article is to provide a legal analysis of the current legislation and identify possible solutions to the legal problems of “green” agriculture, as well as to form a conceptual model of its legal regulation. Using the methods of comparative analysis, legal hermeneutics, and legal modeling, a legal analysis of the modern legal regulation of “green” agriculture is carried out and a conceptual model of its legal regulation is determined, based on which proposals for improving legislation in the considered sphere of public relations are formulated.

The article studies methodological approaches to the environmental assessment of the quality of the environment and the quality of the population of rural settlements. The components of the “rural environment” of life activity include the factors of life support of rural residents or are the resource potential that determine the viability and vitality of the rural environment. The polystructurality of the living environment forms a special functional regime within the boundaries of rural settlements and agricultural activities. At the present stage, the population of rural settlements is experiencing the following negative factors: an increase in morbidity, genetic disorders, mortality, complication of social relations, and economic decline. The life activity of a rural resident is closely interrelated with the natural environment, agricultural activities and has wide spatial boundaries, including various spectra: home, household, objects of agricultural activity. The result of the processing is the compilation of morphometric maps. The map is the basis for creating predictive models for the course of exogenous processes. A monitoring algorithm, which collects data according to the scheme of a typical random nest selection, is important for the environmental analysis of the living environment of rural residents. The sample range, which guarantees the survey of various features of rural settlements, is calculated according to the rules of the sampling method for 145 villages. Rural settlements within the Voronezh region with a population of more than 500 people were studied in terms of medical and demographic indicators.
