Application of the landscape approach and remote sensing data for the mapping of the climate characteristics of the mountain-basin territories
Authors: Rasputina E A , Vasilenko O V 
Published: November 2019

Abstract
Air temperature is one of the most important climate characteristics, which is used for climate research, investigation and modeling of vegetation, hydrological parameters and other landscape components as well as geosystems entirely. The use of a landscape approach greatly simplifies the process of visualizing meteorological parameters and allows you to take into account influencing factors, since they have already been taken into account when drawing up a landscape map. This article describes cartographic models of the air temperature field of the Tunka intermountain basin created using in-situ wide network of modern automatic measuring instruments and remote sensing methods that allow us to solve the problem of climate research at a local level, as well as a landscape-interpretation mapping method. The main advantages and disadvantages of these cartographic methods are assessed. It is shown that a joint analysis of the data from a dense network of field observations, remote sensing data, and a landscape map made it possible to analyze the dynamics of the spatiotemporal distribution of the air temperature field with a relatively high degree of accuracy.
Preservation of the natural potential of vegetation. Assessment in landscape planning
Authors: Novitskaya N I , Suvorov E G 
Published: November 2019

Abstract
The priority purpose of landscape planning is preservation of natural environment with existing ecosystem interrelations under prevailing conditions for the territory development. Analysis of the contemporary state of plant cover is component part of the comprehensive program of studies on landscape planning, which reveals dynamics of vegetation, territorial differentiation, biological variety, degree of territory disturbance communities, and potential of their preservation. Natural stability of vegetation, which is supported not only at the level of biocenosis, but also at the level of spatial current connections of contemporary landscape, is one of the main conditions of preserving the biotope structure. Particularities of development and nature restoration determine ecologically favorable conditions of existence and renewal of plant cover structure. External disturbing factors set additional constraints on the motion of natural dynamics, slowing down restoration or completely leading to irreversible changes. The evaluation of sustainability of plant communities for the southern part of the Lake Baikal coast was carried out on the basis of expert estimation for multifactoral impacts upon dynamics and was represented using a cartographic method in the form of integrated areas of the sustainability of plant communities. Cartographic interpretation of contemporary vegetation state of investigated territory, the determining of the integrated areas of plant community’s sustainability, and further sequential carrying out of interconnected estimation maps, makes possible to differentiate territory in the categories of landscape planning for the complex preservation of natural environment and to develop the necessary measures for stabilization.

Authors: Voropay N N , Vasilenko O V , Cherkashina A A 
Published: November 2019

Abstract
The article presents data on continuous monitoring of the characteristics of the climate system with high spatial-temporal resolution. The study area is the Tunkinskaya rift system of depressions, in particular, the Tunkinskaya and the Mondinskaya depressions. Five cross sections characterizing the typical conditions of mountain-depression landscapes of the South Baikal region were selected. At each point of a cross section, a description of the landscape, laying of the soil section, its description, sampling for subsequent laboratory analyses to clarify the genesis and name were carried out. Meteorological parameters were monitored using stand-alone programmable thermographs. It was shown that the influence of individual and contrasting morphometric characteristics of depressions on the climate is reflected in the characteristics of the temperature and humidity regime as a whole, as well as in the features of the cold and warm period. There is a high spatial heterogeneity of temperatures and precipitation with a noticeable gradient between the peripheral and central parts of depressions. It is also shown that the territory is characterized by the high contrast of geological, geomorphological, phytocenotic and soil conditions, which creates a unique landscape diversity both between different depressions and within each depression.

Authors: Anakhov S V , Matushkin A V , Pyckin Yu A 
Published: November 2019

Abstract
Various methods of gas-vortex stabilization in plasma cutting torches are investigated. The results of the study demonstrate the dependence of the angle of gas injection into the nozzle on the kinematic and kinetic characteristics of plasma jet and, consequently, on the cutting parameters. Increased radial velocity component at the swirler output provides better uniformity of the velocity distribution and kinetic properties of the jet in the affected zone of a cut metal. As a conclusion, it is recommended to use the suggested narrow-jet-plasma technology for cutting thin sheet metals.

Published: November 2019

Abstract
The paper presents the results of an experimental numerical study of the stress state of the rods of a flat truss and the results of the analytical calculation. The values of internal forces and stresses in the truss model were obtained using the SCAD software package, as well as experimentally using the polarization-optical method. The finite element method (FEM) is used to calculate two plane truss models. In the first case, the truss was modeled by rod elements, in the second – by plates. The fields of normal, tangential and principal stresses are obtained. With their help there were found the longitudinal internal forces in the rods of the farm. The interference bands in the model of a flat truss are obtained by the method of photoelasticity. Stresses are calculated with their help. The quantitative and qualitative analysis of the stress state, described in the numerical and physical experiment, is carried out.

Published: November 2019

Abstract
The structure, phase composition of the composite electroexplosion coating of ZnO- Ag system subjected to the irradiation by the high intense electron beam have been studied for the first time. The combined processing including the electroexplosion spraying of the coating of ZnO-Ag system and its subsequent electron beam processing results in the formation of multilayer structure of the coating. The electron beam melts and homogenizes the surface layer of the composite electroexplosion coating of ZnO-Ag system to the depth of 35-40 μm. The effect of the electron beam leads to the formation of the nanocrystalline phases of Ag, ZnO, Cu, CuZn, Ag5Zn8, Cu2O, Ag2O, Cu0.67Zn0.33, AgZn. The dependences of changes in crystal lattice parameters and coherent scattering regions of the phases being formed depending on the processing regime by high intense electron beam have been found.

Authors: Stanica D I , Dumitriu M 
Published: November 2019

Abstract
Ride comfort is one of the criteria for evaluating the dynamic behaviour in railway vehicles, through which the complex sensation triggered by the vibrations in the railway vehicle carbody upon passengers is being described. The behaviour of vibrations along the vehicle carbody is not uniform and the point where the ride comfort is the least convenient can be considered as the carbody critical point. The paper examines the ride comfort along the carbody and the position of the ride comfort critical points in correlation with the speed, carbody flexibility and suspension damping. To this purpose, there are used the results from numerical simulations regarding the ride comfort index calculated along the carbody and the ride comfort index in three points deemed relevant in terms of evaluating the ride comfort at the center of carbody and above the bogies.

Published: November 2019

Abstract
Information Centric Network (ICN) is a promising future networking architecture, while Named Data Networking (NDN) is regarded as ICN’s representative and authoritative scheme. In the recent past, applying ICN/NDN concept in mobile ad-hoc network (MANET), i.e. Named Data Mobile Ad-hoc Network (NDMANET), has attracted a plenty of research efforts. Compared to legacy IP protocol, NDN scheme is considered to be more robust and profitable to the node mobility and the dynamically changed topologies in the MANET domain. This paper focuses on NDMANET’s packet forwarding protocols, which to a large extent decides the efficiency of data dissemination and is a vital module of NDMANET. Firstly, the paper investigates and analyzes some existing packet forwarding protocols, which are widely accepted in NDMANET. On that basis, an innovative distance-aware data forwarding (DDF) protocol is elaborated for NDMANET, with the purpose of further enhancing its network performance. Comprehensive simulation experiments have been conducted and the results illustrate that the proposed DDF protocol can introduce considerable reduction in bandwidth and in energy consumption, with only slightly degrading the response ratio.

Authors: Zhai Kunxian , Zhou Suiping , Li Xiaoping , Liu Yanming 
Published: November 2019

Abstract
In a probe-and-drogue aerial refueling system, the tanker docking system consists of a hose and a drogue. When the receiver approaches the drogue, the dynamics of the drogue may be seriously disturbed by the aerodynamic effect from the receiver which is commonly known as the bow wave effect. In this paper, a numerical simulation method based on potential flow theory is proposed to investigate the bow wave effect. The proposed method is efficient and can be conveniently used in the modelling and simulation of autonomous aerial refuelling system. The results of this method are highly consistent with the CFD results, which demonstrates the effectiveness of the proposed method.

Authors: Bingxiu Guo , Wang Xiaohui , Wang Yanyan , Shao Yue 
Published: November 2019

Abstract
The high-temperature components of aeroengines are in contact with gas flow for a long time, making them susceptible to hot corrosion, which can affect the reliability and lifespan of aeroengines. In this study, five types of superalloys commonly used in the high-temperature components of Aeroengines are selected for gas-based hot corrosion tests, and the corrosion rates are calculated using the weight loss method. Gradient Boosting Regression Tree (GBRT) machine learning algorithm is utilized to establish a corrosion rate forecasting model. The evaluation results show the predictability of this method. The effect of input parameters, including main alloy chemical composition and corrosion time, on the corrosion rate was discussed using GBRT and critical factors are obtained. These results provide a reference for the protection of aeroengines from hot corrosion.

The gap problem made easy?
Authors: Lo Tien-Chun 
Published: November 2019

AbstractByerly recently developed a new solution to the gap problem for cosmological arguments. His idea is that the best explanation for why the necessary being is found to have necessary existence is that it is a perfect being. I raise an objection to Byerly’s solution on the ground that there is some rival naturalistic explanation that is as good as Byerly s theistic explanation.
The function of secondary metabolites in plant carnivory
Authors: Hatcher Christopher R , Ryves David B , Millett Jonathan 
Published: November 2019

AbstractBackgroundCarnivorous plants are an ideal model system for evaluating the role of secondary metabolites in plant ecology and evolution. Carnivory is a striking example of convergent evolution to attract, capture and digest prey for nutrients to enhance growth and reproduction and has evolved independently at least ten times. Though the roles of many traits in plant carnivory have been well studied, the role of secondary metabolites in the carnivorous habit is considerably less understood.ScopeThis review provides the first synthesis of research in which secondary plant metabolites have been demonstrated to have a functional role in plant carnivory. From these studies we identify key metabolites for plant carnivory and their functional role, and highlight biochemical similarities across taxa. From this synthesis we provide new research directions for integrating secondary metabolites into understanding of the ecology and evolution of plant carnivory.ConclusionsCarnivorous plants use secondary metabolites to facilitate prey attraction, capture, digestion and assimilation. We found ~170 metabolites for which a functional role in carnivory has been demonstrated. Of these, 26 compounds are present across genera that independently evolved a carnivorous habit, suggesting convergent evolution. Some secondary metabolites have been co-opted from other processes, such as defence or pollinator attraction. Secondary metabolites in carnivorous plants provide a potentially powerful model system for exploring the role of metabolites in plant evolution. They also show promise for elucidating how the generation of novel compounds, as well as the co-option of pre-existing metabolites, provides a strategy for plants to occupy different environments.
ADDO: a comprehensive toolkit to detect, classify and visualize additive and non-additive quantitative trait loci
Authors: Cui Leilei , Yang Bin , Pontikos Nikolas , Mott Richard , Huang Lusheng 
Published: November 2019

Abstract

Motivation
During the past decade, genome-wide association studies (GWAS) have been used to map quantitative trait loci (QTLs) underlying complex traits. However, most GWAS focus on additive genetic effects while ignoring non-additive effects, on the assumption that most QTL act additively. Consequently, QTLs driven by dominance and other non-additive effects could be overlooked.

Results
We developed ADDO, a highly efficient tool to detect, classify and visualize QTLs with additive and non-additive effects. ADDO implements a mixed-model transformation to control for population structure and unequal relatedness that accounts for both additive and dominant genetic covariance among individuals, and decomposes single-nucleotide polymorphism effects as either additive, partial dominant, dominant or over-dominant. A matrix multiplication approach is used to accelerate the computation: a genome scan on 13 million markers from 900 individuals takes about 5 h with 10 CPUs. Analysis of simulated data confirms ADDO’s performance on traits with different additive and dominance genetic variance components. We showed two real examples in outbred rat where ADDO identified significant dominant QTL that were not detectable by an additive model. ADDO provides a systematic pipeline to characterize additive and non-additive QTL in whole genome sequence data, which complements current mainstream GWAS software for additive genetic effects.

Availability and implementation
ADDO is customizable and convenient to install and provides extensive analytics and visualizations. The package is freely available online at https://github.com/LeileiCui/ADDO.
