Increased Azimuth Resolution by Extrapolating the Antenna Array Aperture Function by Least Squares Linear Prediction Estimation Using Autoregressive Model Coefficients
Authors: Vladimirov V. V.
Published: February 2022

Introduction. Short-wave stations for detecting airborne objects of the ionospheric type have a number of limited technical characteristics, one of which is their low azimuth resolution. This limitation is manifested in the impossibility to separately observe air objects in a group, the distance between which is less than 30 km (at an observation range of 2000 km). The technical characteristics under consideration can be improved by making changes to the dimensions of the receiving antenna array (AA); however, such changes lead, as a rule, to unjustified engineering and financial costs. In practice, space-time signal processing is carried out using conventional superresolution methods, which, although increasing the resolution of the station, decrease the rate of delivery of observation results to the operator due to an additional computational load. It is necessary to find a compromise between the maximum possible resolution indicator and the acceptable load on the system during signal processing.Aim. Analysis of the phase distribution of the incident wave scattered by objects at the AA aperture, as well as the azimuthal images of these objects when performing spacetime signal processing after extrapolating the AA aperture function by evaluating linear prediction using the least-squares method using autoregressive model coefficients.Materials and methods. Modelling of phase distributions at the AA aperture and azimuthal images of the observed objects was conducted in the MATLAB environment.Results. It is shown that the problem of increasing the azimuth resolution of a short-wave station for detecting air objects can be successfully solved using linear prediction based on the least-squares method using autoregressive model coefficients for the extrapolation of the AA aperture function. The results obtained during modelling were analysed using the example of group observation of air objects.Conclusion. The proposed approach for extrapolation of the AA aperture function for short-wave stations with large receiving AAs proved its relevance. The method proposed for increasing the resolution is characterized by a lower computational load, thereby being promising for practical application.

Published: February 2022

Introduction. When synthesizing a prosthesis from ready-made prosthesis units, the prosthetist is faced with the problem of selecting from a large range of components that differ in properties and characteristics. This challenge can be overcome by the creation of a system for processing the patient's biomedical information and its further use as criteria for selecting prosthetic nodes from a global database. For this purpose, an appropriate knowledge base must be incorporated into the system software.Aim. Substantiation of the expediency of presenting the knowledge base about the requirements for the lower limb prosthesis nodes in the form of a matrix model for creating a system of logical filters in the process of selecting nodes from an electronic catalog.Materials and methods. Theoretical research methods were used, including analysis, synthesis and analogy. An expert survey among leading specialists was carried out. To unify the description of the structural and functional state of a disabled person, the terms of the International Classification of Functioning (ICF), Disability and Health were used.Results. At the main stage of filtering, prosthetic modules optimally meeting the patient’s needs are selected using a specialized software application, depending on the patient’s health status and various healthrelated factors. A model of the knowledge base is presented, which describes the logic of selecting prosthetic nodes and their filtering in an electronic catalog.Conclusion. The matrix representation of the knowledge base that contains rules for selecting components of lower limb prostheses, taking into account the patient's condition, is a basis for creating a system of logical filters when searching for prosthetic modules in an electronic catalog for creating customized prostheses. The use of the ICF conceptual language for describing the factors influencing the choice of prosthetic modules is a step towards the formation of a patient’s digital profile, which corresponds to the strategy of transition to digital medicine technologies.

Published: February 2022

The article identifies the difficult situation of the Ukrainian economy, considers the impact of globalization on economic processes, as well as the processes of managing paradigms of industrial enterprises that are part of integrated structures. The analysis of the latest publications of domestic scientists on the topic of enterprise management is carried out. It was determined that in parallel with the "new", digital economy, it is necessary not to destroy, but to save and develop the industrial economy. The main models of making managerial decisions are considered. The processes of creating corporate structures in Ukraine are analyzed. It is substantiated that in the conditions of today's uncertainty, it is necessary to make efforts to save the main branches of Ukrainian industry: metallurgical and machine-building. Based on the generalization of the results of the analysis of integration processes in the field of entrepreneurship, a conclusion was made about the regularity and irreversibility of the process of creating integrated structures in Ukraine. It has been determined that the state should influence the formation of priorities when choosing the type of organizational structures, forms and mechanisms for integrating business structures and give preference to large corporations of the holding type. In order to increase the competitiveness of enterprises, it is proposed for complex integrated systems (holding associations) to make management decisions that combine the use of command-hierarchical and innovative types of management and are based on the use of motivational systems

Authors:   Sumy State University, Pudryk D , Kwilinski O ,   Sumy State University, Nazarenko A ,   Sumy State University
Published: February 2022

The paper generalizes the arguments and counterarguments within the scientific discussion on the migration impact on the countries� economic convergence. European integration in the long run provide for the convergence of the Ukrainian socio-economic development to the level of member states of the European Union (EU). Considering the neoclassical model of growth of Solow-Swan, the convergence of the national economy to the EU could be bosting by intensifying international processes. In particular, the international migration of labor resources allows increasing the amount of private income from abroad, which makes it possible to improve the socio-economic quality of migrant families and achieve the welfare of the EU society. Based on the theoretical analysis of the scientific literature, the authors highlighted the diversified nature of the migration impact on economic growth and economic convergence. The paper aims to determine the migration impact on the Ukrainian and EU economic convergence. The paper�s object is Ukraine and EU member states, which have the common features of long-term development in the economic and political dimensions. The time for analysis is 2000-2020. The methodological basis of the investigation is the concept of s � and b � convergence. The endogenous parameter of the econometric model of b � convergence is the GDP per capita, and exogenous parameters: the volume of private remittances to countries from abroad, the volume of net migration.

Human capital is characterized as a source of resources for the development of the national economy on an innovative basis in terms of its role and place in the structure of intellectual capital. The results of this study are a prerequisite for the development of methodological tools for resource management of innovative development through the realization of human capital potential.
¿Existe isomorfía en los huevos de las especies de la familia Ardeidae (Aves, Ciconiiformes)?

Published: February 2022

Egg shapes in birds reflect many anatomical, biophysical and ecological aspects. In previous literature it has been assumed that a similarity in volumetric indexes from external dimensions is an indicator of constancy in shape of egret eggs (Birds, Ardeidae), but results are not consistent. Previous researchers have used lineal dimension rates to estimate shape, but these can distort the results because both aspects are orthogonal by definition. In the current research we analyze differences in egg shape between eight species of egrets and herons using elliptic Fourier descriptors and landmarks over 203 digital pictures of eggs kept in oological collections. Comparison between species and a discriminate function analysis show that shape is insufficient to distinguish species. The elongation index and breadth of eggs were significantly correlated. Our results suggest that egg shape can discriminate ecological groups but not species, indicating there is no general isomorphy in Ardeidae.

The Strait of Gibraltar has important populations of the highly endangered patellid limpet Patella ferruginea. Between 2006 and 2010, an exhaustive census was carried out in Ceuta. The total coastline was divided into 17 sectors. The coast of each sector was examined by using 10 m transects. For the case of those sectors composed of breakwaters, jetties or islets, no transects were used, and instead, the total number of individuals was recorded. Each individual was measured to the nearest millimetre using a calliper. Moreover, the complete rocky shore length where the species could potentially be present was calculated, and an estimation of the total number of individuals that each sector could host was made. Results indicate that Ceuta could be home to around 44,000 individuals. The species found in Point Benzú, its westernmost limit of distribution on the North African coasts. The largest populations were recorded on the South Bay, with higher Mediterranean influence. Our results indicate that substrate roughness (topographic heterogeneity) and the area’s accessibility highly influence the abundance and population structure. Those populations located on high topographic heterogeneity substrates show higher recruitment rates and lower percentages of larger individuals, while medium to low rugosity surfaces presented the opposite pattern. Additionally, easily accessible areas (and frequented by humans) presented smaller average shell sizes. Implications of the results for conservation purposes are discussed.
Population structure of Atlantic swordfish (Xiphias gladius L. 1758) (Teleostea, Xiphiidae) using mitochondrial DNA analysis: implicationsfor fisheries management

Published: February 2022

Recent studies on Atlantic swordfish (Xiphias gladius L. 1758) genetic structure have demonstrated significant heterogeneity but the precise boundary between populations remains to be identified. In this context, genetic diversity was investigated by PCR-RFLP analysis at the control region of mitochondrial DNA (D-loop) from 274 swordfish specimens collected from five different areas of the Atlantic Ocean. The analysis of molecular variance (AMOVA) showed that genetic variation was mainly due to differences within rather than between the studied areas. Additionally, the phylogenetic analysis did not show evident relationships among haplotypes from all areas. However, low but significant FST values were recorded when comparing Equatorial samples with those from the north central and north tropical Atlantic. These results do not support a need for changing the current management boundary for the Atlantic fishery.

Published: February 2022

Egypt has sought to protect its natural resources and marine biodiversity by establishing a network of six MPAs that are generally located in the Gulf of Aqaba and the Red Sea; most of them include interconnected marine and terrestrial sectors based on conserving coral reefs and accompanying systems. We assessed the present status of MPA networks that showed a set of important results manifested in some strengths (i.e. proper selection according to specific criteria, management plans, etc.), and also some weaknesses (i.e. a relatively small protected proportion of the Egyptian marine territorial waters, significant pressures mainly by tourism activities, etc.). Finally, some recommendations are proposed from this work (i.e. incorporate more habitats that are not well represented in the network, especially on the Mediterranean Sea; establishing a touristic carrying capacity of each area; etc.) to improve the current situation.
Modelling the feeding behavior of Grey Heron (Ardea cinerea) in a coastal wetland of NW Iberian peninsula during the wintering season
Authors:   Univ. of Santiago de Compostela, Spain, Regos A.
Published: February 2022

For a better understanding of the foraging behavior of Grey Heron in an intertidal area we developed predictive models of number of attempts/10′ using Poisson regression. The models were obtained considering the following four variables: age of bird, tidal hours, bi–monthly period, and substrate type, obtaining a total of 15 models. The most parsimonious model obtained using the Akaike Information Criteria included tidal hour, age of bird and substrate type as predictive variables. The mean number of attempts/10′ was highest in the four hours around low tide and in water and muddy substrates, while foraging activity was scarcely recorded in sandy substrates. No differences of effectiveness were found between adult and juvenile birds. Grey Heron showed preference for very small and small prey, increasing handling time with prey length.

Published: February 2022

In this paper I provide an overview of conservation genetics and describe the management actions in the wild that can benefit from conservation genetic studies. I describe the genetic factors of risk for the survival of wild species, the consequences of loss of genetic diversity, inbreeding and outbreeding depression, and the use of genetic tools to delimitate units of conservation. Then I introduce the most common applications of conservation genetics in the management of wild populations. In a second part of the paper I review the conservation genetic studies carried on the Iberian raptors. I introduce several studies on the Spanish imperial eagle, the bearded vulture, the black vulture and the red kite that were carried out using autosomal microsatellite markers and mitochondrial DNA (mtDNA) sequencing. I describe studies on the lesser kestrel and Egyptian vulture that additionally applied major histocompatibility complex (MHC) markers, with the purpose of incorporating the study of non–neutral variation. For every species I explain how these studies can be and/or are applied in the strategy of conservation in the wild.

Anti–predator training of juvenile little owls was tested in a sample of recovered owls raised in captivity in Brinzal Owl Rescue Center (Madrid, Spain). Mortality caused by predators has been described previously in released individuals. Nine little owls were conditioned during their development to a naturalized goshawk and a large live rat, whose presence was paired to the owl’s alarm call. All nine owls and seven non–trained individuals were then released during the late summer and autumn and radio–tracked for six weeks to test their survival. In total 71.4% of the trained owls survived while only the 33.3% of the untrained group were alive at the end of week six. The only cause of death that was detected was predation. Antipredator training, therefore, seems to be beneficial in maximizing survival after the release of juvenile little owls.
Payment of Money in Lieu of the Crime of Corruption in the Recovery of Assets
Authors: Helmi Helmi
Published: February 2022

In terms of sanctions, the Law on the Eradication of Criminal Acts of Corruption adheres to a double track system, in the sense that in addition to criminal sanctions, it also contains civil sanctions, namely additional penalties in the form of payment of replacement money. So that the law enforcement of corruption in addition to being oriented to “follow the suspect” and “follow the money”, to recover state financial losses. The purpose of this research is to analyze the criminal urgency of paying replacement money in corruption crimes and to analyze the criteria for corruption crimes that can be imposed with additional criminal sanctions. This legal research is a prescriptive normative legal research, with a law approach and a concept approach, using primary and secondary legal materials. The results of this study, (a). The urgency of imposing a penalty for paying compensation is to recover state financial losses from corruption, in which case corruption involving state finances is an act that robs the community of socio-economic rights as stated in the 1945 Constitution, and the penalty for replacement money that has been paid by the convict can be used to “promote the general welfare”. (b). The criteria for imposing a substitute money penalty are: (1). the criminal act of corruption committed by the defendant has caused state financial losses; (2). The defendant has obtained property from the act of corruption he has committed; and (3). The defendant has not returned the state financial loss in the amount of the property he has obtained.

Si bien el fenómeno puede observarse en una gran cantidad de trastornos, se ha asociado en más del 90 % de los casos a neoplasias de células B, hepatitis C y enfermedades autoinmunes.El porcentaje restante, llamado crioglobulinemia esencial se caracteriza por un curso más severo y agresivo de la enfermedad junto con una peor respuesta terapéutica. El presente artículo describe el caso de una paciente afecta de Crioglobulinemia esencial, en la que su mala evolución, a pesar del tratamiento conlleva a amputación final transmetatarsiana.

El mieloma no secretor constituye una forma excepcional de mieloma (1% de los casos). Se trata de un subtipo que no presenta pico monoclonal ni en suero ni en orina. El estudio de cadenas ligeras libres en suero también resulta negativo. La fragilidad ósea y dolor óseo, especialmente si asocian anemia, hipercalcemia e insuficiencia renal, orientan hacia su existencia. Se presenta el caso de una mujer de 76 años con aplastamientos vertebrales y dolor óseo difuso finalmente diagnosticada de mieloma no secretor en fase avanzada. De esta forma, se pretende concienciar sobre la existencia para un diagnóstico y tratamiento precoces.

La osteomielitis púbica es una variante rara de infección ósea que se produce secundariamente a la siembra bacteriana hematógena o por inoculación directa. Clínicamente cursa con dolor púbico agudo intenso, limitación de la marcha, fiebre elevada, leucocitosis y elevación de reactantes de fase aguda. En una minoría de pacientes el cuadro clínico aparece en relación al ejercicio físico vigoroso. El diagnóstico diferencial debe establecerse con la osteítis púbica. Presentamos el caso de una mujer de 15 años, con clínica típica, antecedente de actividad deportiva y hemocultivos positivos para Staphylococcus aureus, como perfil de paciente tipo para esta entidad.

Білок розпізнавання пептидогліканів (PGRP) є важливим рецептором розпізнавання паттернів, який міститься як у безхребетних, так і у хребетних. Він відіграє важливу роль в антибактеріальному імунітеті, завдяки своїй помітній здатності виявляти та усувати збудника інфекції. Однак PGRP, в основному ідентифіковано з Drosophila melanogaster та Bombyx mori, а щодо інших сільськогосподарських комах повідомлень мало про їхні функції та механізм. У цьому дослідженні короткотиповий ген PGRP під назвою GmPGRP-SC був ідентифікований у Grapholitha molesta – східної плодожерки (OFM) – на основі аналізу бази даних груп транскрипції OFM з нашої лабораторії та Національного центру інформації з біотехнологій (https://www.ncbi.nlm.nih.gov/). GmPGRP-SC містить домен PGRP і має найтісніший генетичний зв'язок з геном PGRP Leguminivora glycinivorella, відповідно до послідовності та філогенетичного аналізу. Метод ПЛР у реальному часі було використано для аналізу картини його експресії на стадіях розвитку OFM та в різних тканинах личинки OFM. Наразі, відносно рівні експресії гена GmPGRP-SC в OFM були проаналізовані після інфікування Beauveria bassiana. Результати показали, що загальна кДНК від GmPGRP-SC становила 3221 bp (базових, основних пар), а кодуючі області – 2268 bp, що кодують 756 амінокислотних залишків. Рівень експресії GmPGRP-SC був найвищим у стадії лялечки OFM. Водночас, у різних тканинах OFM його відносна експресія була вищою в епітелії та гемоциті, тоді як іншим стадіям та тканинам притаманна порівняно нижча та з невеликою різницею. Рівень експресії GmPGRP-SC був істотно різним, коли суспензія спор B. bassiana становить 105 конідій/мкл, інфікованих через 48 годин. Тоді, коли суспензія спор B. bassiana становить 107 конідій/мкл, рівень експресії GmPGRP-SC також був різним. Усі ці результати закладуть основу для вивчення ролі та функцій GmPGRP-SC у вродженому імунітеті OFM, а також сприятимуть подальшому вивченню молекулярної взаємодії між OFM та B. bassiana. Результати досліджень можуть допомогти знайти потенційні молекули-мішені та забезпечити наукову основу для розробки нових біогенних пестицидів та реалізації Зеленої боротьби зі шкідниками (GPM).

This study focuses on the econometric analysis of determinants of international migration of overseas Filipino workers across different countries. The number of overseas Filipino workers as the regressand, while the regressors are remittances, unemployment, and wage rate, using time-series data from years 1990 to 2019. The selected variables are considered as a few of the major economic factors why Filipino workers migrate. Other determinants or factors of migration were not examined by the researchers. This study discovered that remittances, wage rate, and unemployment rate are statistically significant and positively correlated to the parameters of overseas Filipino workers in the Philippines. It is determined that remittances are positively correlated with the number of overseas Filipino workers. In addition, it was discovered that the unemployment rate and the number of overseas Filipino workers are negatively correlated in the absence of the wage rate and remittances in the simple linear regression. However, due to the influence of the wage rate and remittances in the model, the relationship of the unemployment rate with the number of overseas Filipino workers proves to be positively correlated. The obtained value of the model suggests that 91.21% of the variability in overseas Filipino workers can be explained by the variability of all independent variables. Furthermore, as indicated by the diagnostic tests' result, including the Pearson R correlation coefficient, the overall model is significant and shows no evidence of multicollinearity, serial correlation, heteroscedasticity, and irregular distribution of residuals.

Culture is an idea or a system of ideas that arise as a result of the social behavior of society. The existing system in culture includes norms, values, views of life, and one of them is belief. Belief itself is supported by the values ​​and customs that are believed by certain communities and carried out from generation to generation. Gradually, the culture will form a pattern of needs, such as rituals and places of worship. It is known that, places of worship that already exist in Indonesia have different characteristics with the concept of belief in each region. These different and diverse characteristics are clear evidence of differences which are at the same time a cultural wealth for the face of the region itself. This makes architecture one of the concrete manifestations of culture and fulfillment of needs, this embodiment can reflect the identity of the area. From the analysis carried out, it can be concluded that architecture is a tangible form of the face of a culture, one of which is in terms of belief or religion and in the process of making this journal, this study uses data collection methods from various sources
INFRASTRUCTURE BUILDING ADJUSTMENT IN THE COVID-19 PANDEMIC
Authors: Yuliana Yuliana
Published: February 2022

Infrastructure building adjustment must be done during the COVID-19 pandemic to ensure the health protocol implementation. The permanent buildings cannot be changed. Therefore, the infrastructure building adjustment need to be done. There are some modifications on the places and sites, also addition of specific instrument to ensure the good air circulation. This paper aims to describe the adjustment of infrastructure building during the COVID-19 pandemic. Method: This is a narrative literature review. Articles were searched in Science Direct, PubMed, and Google Scholar. The articles were selected based on title, abstract, and full-text screening. Results of literature review revealed that the buildings should have at least an air purifier as filter and open windows to ensure the good airflow. The recirculated air from the surrounding people without circulation increases the risks of COVID-19 transmission. Joining rooms such as joined kitchens or living rooms must not be used during this time. If the room is very important and must be used together, then there should be a break period from one user to another user. This break time is important to allow fresh air circulation. The important factors in building adjustment and modification are cost, health aspects, function, and the users’ safety. In conclusion, the adjustment of infrastructure building during the COVID-19 pandemic can be implemented by maintaining the good air circulation flow in the room, using an air purifier as a filter, and ensuring a break period for users in using joining rooms.

Published: February 2022

This paper describes a methodology for optimal seismic design of reinforced concrete 3D columns and bent caps (beams) of bridges. Design variables include compressive strength of concrete, geometry, as well as longitudinal and shear reinforcement of columns and beams. The optimization is performed to minimize the cost and CO2 emissions using the enhanced colliding bodies optimization (ECBO) algorithm. The trade-off between cost and CO2 emissions shows that in the design for minimizing CO2 emissions compared to the design based on the cost minimization, increasing 1.4 % in cost can decrease CO2 emissions by 6.1%.
