Assessment of the saline biotope state of the North-Western Pryazovia as breeding sites of Glareola pratincola with the help of remote sensing data
Authors: Vynokurova S V 
Published: July 2022

Abstract
Given the biology features of the pratincola (Glareola pratancola), the possibilities of using remote sensing data were studied for the assessment of the species breeding habitats. Sentinel-2 images allowed analyzing a number of vegetation indexes reflecting such specific habitat characteristics as humidity and vegetation cover. The surface temperature is also was investigated. Moreover, the GIS analysis revealed spatial distribution of the collared pratincola breeding colonies, primarily in relation to water sources, settlements and roads. Glareola pratancola chooses saline areas as breeding habitats, which are characterized by a wide range of values of vegetation indices: NDVI is from 0.143246 to 0.365503, MSI is from 0.987138 to 1.3531. All saline areas suitable for breeding were located in close proximity to the water body (not more than 300m). The possible impact of the proximity of settlements and roads on the location of breeding colonies was not found. The salt marshes used by pratincoles for breeding were situated at an average distance of 1405 ± 386m from settlements and 1714 ± 274m from roads. The main disturbance factor is potentially cattle grazing. Accoding to results the North-Western Pryazovia is a significant breeding place for Glareola pratincola on the Azov-Black Sea coast of Ukraine. The obtained data can be used to determine an ecological niche of the collared pratincole and to develop its conservation strategy in North-Western Pryazovia.

Abstract
The current idea of the phenomenon of human health is strongly associated with a harmonious, well-developed personality. A healthy person in all respects can be called one who adequately responds and adapts to the changing conditions of the ecological, biological and social environment. The main prerequisites for health are the stability of the bioecosystem and sustainable resources. Aim/tasks is the theoretically substantiate the information-structural model of human health and the characteristics of its components. The theoretical and methodological basis of the work was the synergistic use of the principles of science and a systematic approach, which led to the choice of research methods: general scientific (analysis, synthesis, systematization, generalization of literary sources); interdisciplinary (structural-system approach, axiological method). Based on the use of the method of information-structural modeling, the modern trend of natural science is substantiated, which is the key to the stability of the bioecosystem - the information model of human health. It consists of the following blocks: information field of knowledge of the main subject areas; information and technological base of research; information and organizational management tools. The basics of a new interdisciplinary approach to the formation of a generalized idea of the phenomenon of human health from the standpoint of information-structural modeling: systematized information concept of integrated health as a unity of physical, mental and social health, verified it, obtained information about the system in as a whole by translating verbal-qualitative information into quantitative assessments. Conclusions. It is emphasized that the information space of individual health statuses is a holistic multidimensional dynamic system of a certain structure, in which the system-hierarchical homeostasis of interaction of physical, mental and social health statuses at different hierarchical levels is realized. It is proved that the information concept of the phenomenon of human health promotes the further integration of various data, builds constructive ways to formalize complex natural objects, and determines the stable functioning of the bioecosystem.

Published: July 2022

Abstract
The ecological state deterioration of the biosphere contributes to the formation of structural-functional mechanisms of plants’ adaptation to the synergistic influence of negative factors at different levels of living systems’ organization. A complex algorithm of the plant organism reaction response to any adverse factor includes a wide range of histological-metabolic adaptive mechanisms that provide a nonspecific reaction and are responsible for increasing the plant organism resistance. Aim is the investigation of endo-adaptive specificity of mesophytic plants’ formation as an ecosystem resistance component. Methods are experimental research, quantitative and anatomical analysis, mathematical and statistical processing of the obtained data. The article presents the histological-functional specificity of Portulaca oleraceae L. vegetative organs under chloride load and without it in the Ukrainian south conditions. It is proved that the various parameters study of plants’ metabolism and anatomical-morphological reconstruction plays an important role in studying the salt resistance mechanisms, which determine the existence of mesophytic plants under stressful environmental changes. It is shown that adaptability is an equal component of two interdependent processes (the development of damage caused by stressors and the restoring the values of structural-functional parameters), which generally forms an endo-adaptive mechanism of plant functioning and ensures steadiness of ecosystem stability.

Abstract
Ukraine has all the preconditions to increase the sugar beet yield, but, at present, comprehensive studies of spatio-temporal variation in the yield of sugar beet in the country have not been conducted. Though, such research is essential for the formation of crop management and yield forecasting in the future. The study aim is to analyze the general spatio-temporal dynamics of sugar beet yield within 10 regions of Ukraine, to identify the determinants of this trend and to characterize the areas of Ukraine regarding the sugar beet yield. Several statistical methods have been applied to the average sugar beet yields data which were provided by the State Statistics Service of Ukraine. The Akaike Information Criterion (AIC) was used to estimate the likelihood of a statistical model to the observed data. To calculate the global spatial autocorrelation coefficient, I-Moran statistics were computed using the Geoda095i program. A spatial database was created in ArcGIS 10.2. The average sugar beet yields within the study area ranged from 154.5 dt/ha to 495.7 dt/ha. The spatio-temporal trend of sugar beet yield has been described by a fourth-degree polynomial. It was determined that the overall trend of sugar beet yields is determined by agroeconomic and agro-technological factors, whose contribution to the yield variation is 72-96%. The areas where high sugar beet yields are ensured by favorable natural conditions, such as soil fertility, were identified, as well as areas with high crop yield potential provided that agricultural and breeding techniques are adequately used.

Published: July 2022

AbstractThe study of the long-term effects of toxic substances, in particular, heavy metals, on aquatic organisms is currently a topical issue, due to the increase of anthropogenic pressure on the hydrosphere. The embryonic and juvenile stages of mollusks are more sensitive to toxic effects than adult ones. Consequently, the effects of different concentrations of heavy metal in the aquatic environment on the growth and survival rates ofLymnaea stagnalisjuveniles were evaluated. In a chronic toxicological experiment, we used chronic lethal, sublethal, and subthreshold concentrations of heavy metals. We conducted 12 toxicological chronic experiments, lasting 60 days, with 1070 specimens of L.stagnalisjuveniles. The toxic effect of heavy metals exposure in the aquatic environment in young individuals is manifested at much lower concentrations than in adults. The heavy metals ions affect the shell height ofL. stagnalisjuveniles even at the embryonic stage, which is manifested in some cases in the acceleration of their growth, in others – in its slowing down. The chronic experiment indicated that the values of shell height growth of juveniles in most cases correlate with the values of the total body weight growth. Under the influence of sublethal concentrations of heavy metal ions, the survival rates of juveniles are 3–4 times lower than the control. In solutions containing chronic lethal concentrations of Co2+and Mn2+, up to 80–90% of juveniles die. The sharper and more rapid response of young snails to toxic effects compared to adult animals can be explained by embryo intoxication.

Abstract
Providing a favourable and comfortable living environment for the population is one of the main tasks of optimising urban development. The level of comfort is formed with the territorial interaction of natural and socio-economic conditions for the region’s development. This interaction is especially manifested in large industrial centres, characterised by a strong negative anthropogenic impact on the environment. The territorial assessment of the comfort of the living environment involves a comprehensive spatial analysis of the population comfort main factors. The purpose of this work is a spatial analysis of the population living comfort of one of the most industrialised regions not only Ukraine, but also Europe – the city of Kryvyi Rih. Functional zoning was carried out using GIS Map Info with the allocation of the following areas: residential zones, public and business zones, industry and warehouse zones, resort and recreation zones. The distribution of the residential area according to the level of comfort of the population living environment was carried out according to 3 groups of factors: transport accessibility, development of social infrastructure and ecological state. The first group characterises the habitat from the point of view of the city’s provision with transport routes for various types of public transport. The second group characterises the population’s social conditions, namely the number of educational, cultural and medical institutions. The third block includes the ecological state of the territory according to the criterion of atmospheric pollution. The method of scoring made it possible to compare individual parts of the area under study across the entire range of natural, ecological and social population comfort. The combination of indicators of the totality of all three groups factors was carried out using overlay operations. As a result of the research, a map characterising the spatial differentiation of indicators of the living comfort in the city of Kryvyi Rih has been created. The specialisation of the city as a large industrial centre has determined the leading role of the group of environmental indicators in the situational model of the living environment comfort in the region.

Abstract
The historical development of water supply systems for portable and irrigation water gathering is traditional for lack of water regions of the world. The diversity of such systems can be observed at Middle East and Asiatic cultures. Some of them are still in use or partly in use now. The study cases of the work are traditional distribution systems of rainwater in the deserted M’zab Valley, Algeria and tropical Miyakojima Island, Japan. The research is aiming to precise the modern situation of traditional water supply systems estimating the possible ways of theirs sustainable development and revitalization. The research conducted on the case grounds mainly with field studies and interview methods. The water supply system of M’zab has been implemented more than eight centuries ago and is still in use. It is a complex hydraulic system based on the principle of total utilization of torrent water and on the equitable division of this water over the entire oasis. Local people now beginning to understand its cultural significance aiming to popularise it. Miyakojima Island medieval water supply underground system consist of the network of cave sources integrated with architecture. Now it is in decay not using like a source of potable water but still preserving some sacral significance with not pointing on popularization. For the sustainability and revitalization of the traditional water supply systems now it is not enough to preserve their initial function but also need to develop the potency of tourist attraction with reservation as cultural property.

Abstract
The scale and nature of changes in the urban planning parameters of the Luhansk region under the influence of socio-demographic and external factors are studied. The actual development trends of the Lysychansk-Rubizhne-Sievierodonetsk agglomeration, the evolution of the regional settlement system, the state and problems of the urban development of the region are determined. To conduct the study, methods of system analysis, analytical comparisons, statistical analysis, urban planning analysis were used. The information base consists of literary and archival sources, cartographic materials. Quantitative and qualitative changes in the main territorial and urban planning parameters of the Luhansk region have been studied. A methodology for assessing and making urban planning decisions is proposed. The urban planning tasks and directions of transformation of the residential environment of the Luhansk region, controlled by Ukraine, are analyzed. Lugansk region in modern conditions is an outsider of socio-economic development. The occupied territories of the Lugansk region of the so-called ORLO (separate districts of the Luhansk region) are in a state of crisis. Industrial, ecological, social degradation is intensifying. This trend can lead to the devastation of settlement systems. The tasks of rational transformation of the territorial-planning organization of the Lugansk region remain relevant. From the intermediate conclusions, it is advisable to single out: the region has significantly changed its functions. The border and the line of demarcation of the JFO will still indefinitely be the determining factor influencing the state and development of the region. The task of the territorial development should be considered at the level of the Lysychansk-Rubizhne-Sievierodonetsk agglomeration and the structure of the region as a whole to ensure the growth of its potential. It is expedient to implement priority tasks according to unconditionally effective options that give a quick and demonstrable result. It can be education, transport infrastructure, anything that raises social standards. It is necessary to achieve a consensus of different groups of the population in the implementation of urban planning tasks and projects.

Abstract
The ability of a society for sustainable development is determined by its ability to maintain and develop the parameters of life within the security corridor not least under the condition of continuous action of both internal and external factors. The connection between the activities of law enforcement agencies and the sustainability development of socio-territorial communities is obvious since the leading mission of the police is to prevent the constantly growing threats associated with various kinds of offenses. It is well known that the development of public opinion is an integral part of the rule of law and civil society. In the context of active reformation of law enforcement agencies, empirical sociological studies play the role of a measurer of efficiency, a barometer of public trust. The leading task of sociologists is to establish a two-way communication with the population whose security should be ensured by law enforcement officials. The article summarizes the experience of existing empirical sociological research of public opinion on the evaluation of the formation of a new methodology and methods of evaluating the effectiveness of the police. The authors of the article note that to date, considerable research experience has been accumulated, a base of empirical research has been formed to study the effectiveness of the national police, but there is still some methodological and methodological inconsistency. Researchers point to the appropriateness of using the in-depth interview method of the police officers themselves, conducting a focus group and expert evaluation.
Reconfigurable InP waveguide components using the Sb2S3phase change material

Published: July 2022

AbstractReconfigurable waveguide components are promising building blocks for photonic neural networks and as an optical analogue to field-programmable gate arrays. By changing the effective index of the waveguide, reconfigurable waveguide components can achieve on-chip light routing and modulation. In this paper, we design and demonstrate an Sb2S3-reconfigurable InP membrane Mach–Zehnder interferometer (MZI) on a silicon substrate. Sb2S3, which has tunable refractive index and low absorption in the near-infrared spectrum, was patterned on the InP waveguide MZIs to make an optical switch in the telecoms conventional-band. By laser induced crystallisation of the Sb2S3, it was possible to control interference in the MZI and achieve 18 dB on/off switching at 1540 nm. Laser reamorphisation and reversible switching of the Sb2S3layer resulted in damage to the waveguide structure. However, simulations show that transition metal di-chalcogenide two-dimensional crystal layers can act as efficient thermal barriers that prevent thermal damage to the waveguide during laser amorphisation. Therefore, combining Sb2S3with InP waveguides seems to be a feasible approach to achieve low-loss reprogrammable waveguide components for on-chip photonics routing and neural networks.
Few-cycle excitation of atomic coherence: an analytical solution beyond the rotating-wave approximation

Published: July 2022

Abstract
Developing an analytical theory for atomic coherence driven by ultrashort laser pulses has proved to be challenging due to the breakdown of the rotating wave approximation (RWA). In this paper, we present an approximate analytical solution that describes a two-level atom under the excitation of a far-off-resonance, few-cycle pulse of arbitrary shape without invoking the RWA. As an example of its applicability, a closed-form solution for Gaussian pulses is explicitly given, and the result is used to analyse the impact of carrier envelope phase on atomic population ratios. Comparisons with numerical solutions validate the accuracy our solution within the scope of the approximation. Finally, we outline an alternative approach that can lead to a more accurate solution by capturing the nonlinear behaviors of the system. The work lays out feasible theoretical paths toward analytically describing two-level atoms driven by ultrashort pulses.
Layered complex networks as fluctuation amplifiers
Authors: Tyloo Melvyn 
Published: July 2022

Abstract
In complex networked systems theory, an important question is how to evaluate the system robustness to external perturbations. With this task in mind, I investigate the propagation of noise in multi-layer networked systems. I find that, for a two layer network, noise originally injected in one layer can be strongly amplified in the other layer, depending on how well-connected are the complex networks in each layer and on how much the eigenmodes of their Laplacian matrices overlap. These results allow to predict potentially harmful conditions for the system and its sub-networks, where the level of fluctuations is important, and how to avoid them. The analytical results are illustrated numerically on various synthetic networks.

Abstract
Quantum technology grown out of quantum information theory, including quantum communication, quantum computation and quantum sensing, not only provides powerful research tools for numerous fields, but also is expected to go to civilian use in the future. Solid-state spin-active defects are one of promising platforms for quantum technology, and the host materials include three-dimensional diamond and silicon carbide, and the emerging two-dimensional hexagonal boron nitride (hBN) and transition-metal dichalcogenides. In this review, we will focus on the spin defects in hBN, and summarize theoretical and experimental progresses made in understanding properties of these spin defects. In particular, the combination of theoretical prediction and experimental verification is highlighted. We also discuss the future advantages and challenges of solid-state spins in hBN on the path towards quantum information applications.
