Treatment-Free Remission in Chronic Myeloid Leukaemia: Can We Identify Prognostic Factors?
Authors: Saifullah Hilbeen Hisham , Lucas Claire Marie
Published: June 2021

Following the development of tyrosine kinase inhibitors (TKI), the survival of patients with chronic myeloid leukaemia (CML) drastically improved. With the introduction of these agents, CML is now considered a chronic disease, for some patients. Taking into consideration the side effects, toxicity, and high cost, discontinuing TKIs became a goal for patients with chronic phase CML. Patients who achieved deep molecular response (DMR) and discontinued TKI, remained in treatment-free remission (TFR). Currently, the data from the published literature demonstrate that 40-60% of patients achieve TFR, with relapses occurring within the first six months. In addition, almost all patients who relapsed regained a molecular response upon re-treatment, indicating TKI discontinuation is safe. However, there is still a gap in the understanding the mechanisms behind TFR, and whether there are prognostic factors that can predict the best candidates who qualify for TKI discontinuation with a view to keeping them in TFR. Furthermore, the information about a second TFR attempt and the role of gradual de-escalation of TKI before complete cessation is limited. This review highlights the factors predicting success or failure of TFR. In addition, it ex-amines the feasibility of a second TFR attempt after the failure of the first one, and the current guidelines concerning TFR in clinical practice.

Intelligent systems are transforming the world, as well as our healthcare system. We propose a deep learning-based cough sound classification model that can distinguish between children with healthy versus pathological coughs such as asthma, upper respiratory tract infection (URTI), and lower respiratory tract infection (LRTI). In order to train a deep neural network model, we collected a new dataset of cough sounds, labelled with clinician's diagnosis. The chosen model is a bidirectional long-short term memory network (BiLSTM) based on Mel Frequency Cepstral Coefficients (MFCCs) features. The resulting trained model when trained for classifying two classes of coughs -- healthy or pathology (in general or belonging to a specific respiratory pathology), reaches accuracy exceeding 84\% when classifying cough to the label provided by the physicians' diagnosis. In order to classify subject's respiratory pathology condition, results of multiple cough epochs per subject were combined. The resulting prediction accuracy exceeds 91\% for all three respiratory pathologies. However, when the model is trained to classify and discriminate among the four classes of coughs, overall accuracy dropped: one class of pathological coughs are often misclassified as other. However, if one consider the healthy cough classified as healthy and pathological cough classified to have some kind of pathologies, then the overall accuracy of four class model is above 84\%. A longitudinal study of MFCC feature space when comparing pathologicial and recovered coughs collected from the same subjects revealed the fact that pathological cough irrespective of the underlying conditions occupy the same feature space making it harder to differentiate only using MFCC features.

In this paper, using the Feigenbaum logistic map, mathematical modeling of the spread of waves of the coronavirus epidemic in different countries is carried out. It is shown that the chosen model is optimal for describing the complex dynamics of the spread of infections in open, heterogeneous systems with inaccurately specified statistical data. A method for detecting local epidemic waves and determining the model parameters has been developed. It is shown that the model makes it possible to describe statistical data well and make realistic forecasts. The model is used to model the total number of cases, the total number of deaths, recoveries, and the calculation of active cases.
The digital platform of the future school: the digital-cognitive approach against the digital-algorithmic reduction of educational practice
Authors: Gromyko Yury Vyacheslavovich , Rubtsov Vitaly Vladimirovich
Published: June 2021

The paper differentiates two approaches to digitalization of the educational practice: the digital-algorithmic approach and the digital-cognitive approach. The digital-algorithmic approach puts in correspondence pupil’s answer with described and established rules and operations to achieve “correct” responses. Application of the first approach forces students to guess right operation sequence to find the right solution. The digital-cognitive approach provides a background for modeling, visualizing and making representation of thinking acts and action for school students and teacher. Realization of the second approach aims to organize the digital educational milieu of the new generation. This the digital educational milieu supports and stimulates student work to find types of operations, the operation set and the operation sequence according to student’s understanding of the problem and grasping the situation. The model of the thinking act that is elaborated by Vasiliy Davydov as the “cell” for the interdisciplinary theory of thought processes is considered to be the core for constructing a digital educational milieu of the new generation. Described forms of thinking act with increasing complexity provides organization of digital-cognitive systems in education.
Digital transformation in the focus of transdisciplinarity of philosophical knowledge
Authors: Lazarevich Anatoly Arkadievich
Published: June 2021

From the perspective of interdisciplinary and transdisciplinary synthesis, there was studied the conceptual and methodological certainty of the existing approaches to understanding digital transformation. The author proceeds from the fact that digital transformation is not only the new technology (artificial intelligence, blockchain, data analysis, Internet of things etc.), but also a deep transformation of the basics of life, the structure of organizations and enterprises, society as a whole. In other words, it is a fundamental transformation of traditional models of life organization, construction, and development of a new reality, which is not always tolerant to humans. Thus, digital transformation is considered as essential characteristic of the modern era, the formation of which was influenced by a number of factors of social dynamics. The key factors are informatization and total digitalization. These processes caused formation of new sociality, which was different from the previous types of civilizational development with a sharp increase of the role of temporal and artificial component in the structure of social-biological evolution. In conditions of intensive social dynamics, choice remains an essential characteristic of new sociality. At the same time, the subjective side of social choice is changing: it is not an atomic personality, group, institution, but a high tech social practice taken from the point of view of the system of interaction of agents that realize the social-economic expediency in line with intensive innovation transformation. There is substantiated the increasing importance of modern social-humanitarian knowledge as conceptual-categorical and methodological base of reflection and prediction of the processes of formation of new sociality. In the structure of scientific-methodological reflection, there is actualized the transdisciplinary status of philosophical knowledge and its potential in connection with new instrumental-technical capabilities of cognitive practice.

New design and comparative study via two techniques for wind energy conversion system
Authors: Mahgoun M. S. , Badoud A. E.
Published: June 2021

Introduction. With the advancements in the variable speed direct drive design and control of wind energy systems, the efficiency and energy capture of these systems is also increasing. As such, numerous linear controllers have also been developed, in literature, for MPPT which use the linear characteristics of the wind turbine system. The major limitation in all of those linear controllers is that they use the linearized model and they cannot deal with the nonlinear dynamics of a system. However, real systems exhibit nonlinear dynamics and a nonlinear controller is required to handle such nonlinearities in real-world systems. The novelty of the proposed work consists in the development of a robust nonlinear controller to ensure maximum power point tracking by handling nonlinearities of a system and making it robust against changing environmental conditions. Purpose. In the beginning, sliding mode control has been considered as one of the most powerful control techniques, this is due to the simplicity of its implementation and robustness compared to uncertainties of the system and external disturbances. Unfortunately, this type of controller suffers from a major disadvantage, that is, the phenomenon of chattering. Methods. So in this paper and in order to eliminate this phenomenon, a novel non-linear control algorithm based on a synergetic controller is proposed. The objective of this control is to maximize the power extraction of a variable speed wind energy conversion system compared to sliding mode control by eliminating the phenomenon of chattering and have a good power quality by fixing the power coefficient at its maximum value and the Tip Speed Ratio maintained at its optimum value. Results. The performance of the proposed nonlinear controllers has been validated in MATLAB/Simulink environment. The simulation results show the effectiveness of the proposed scheme, suppression of the chattering phenomenon and robustness of the proposed controller compared to the sliding mode control law.

Published: June 2021

The introduction of battery energy storage systems and the subsequent transfer of electricity is a very important task, which is solved in different countries in different ways, based on the types of products that can be provided by battery energy storage systems. The analysis of the structure of generating capacities in the United Electric Power System of Ukraine shows a significant deficit of shunting capacities, among which today there is thermal generation, which has a significant level of wear of the main generating equipment and hydroelectric power plants. Based on the above, it would be logical to assume that with the launch of a new model of the electricity market; market segments will be formed in which price signals will be attractive for investment in new shunting capacity. However, the formation of such signals is limited by the establishment of upper price indices on the additional service market and market day ahead. Thus, to simulate the operation of battery energy storage systems, the additional service market was chosen in which the system operator purchases services from additional service providers. Modeling the operation of battery energy storage systems for the provision of additional services is a multi-criteria task that takes into account both the technical features of the battery energy storage systems and the relevant price indices that have been formed for each type of service. The paper considers the possibility of providing services from the automatic reserve of frequency recovery and the provision of balancing services. Based on statistical data on the additional service market of the integrated power system of Ukraine, developed a mathematical model to assess the effect of the use of battery energy storage systems to provide services for primary, secondary and tertiary frequency control. The relationship between the price indices of additional service market and technical and economic characteristics of the battery energy storage system are determined. The target function is offered in the mathematical model of operation of the battery energy storage systems, which takes into account the reduced costs for the accumulation of a unit of electricity, maintenance costs and income from the provision of services on the additional service market.
CONSTRUCTIVE DESIGN AND FEATURES OF THE PROCESSES IN THE ROASTING SHAFT FURNACES BY USING GASEOUS FUEL
Authors: Vytiaganets Valentin , Shaporev Valeriy , Pitak Inna , Baranova Antonina
Published: June 2021

The article analyzes shaft furnaces for lime production. According to the method of firing, shaft furnaces are of bulk type, semi-gas type, gaseous and liquid fuels. The disadvantages of the operation of the main modern kilns during lime burning have been established. The main aggregates for high-tonnage lime production are mine lime kilns, in which blast furnace coke or anthracite, or high-quality coals are used as fuel. Generally, lean fuels are used in industries where, together with the technological cycle, carbon dioxide is used, which are contained in flue gases with a concentration of 36−40%mass. The data on the operation of six furnaces on the territory of Ukraine at the enterprises showed that gas shaft furnaces of cylindrical and slotted type with a straight-lining profile were widely used. The parameters of such furnaces are productivity from 100 to 250 tons per day, shaft diameter from 3.2 to 5.4 m, and height 6−8 furnace diameters. Most often, they use heating systems with central and two rows of peripheral injection burners without protrusion. The most critical part of all furnaces is the distribution of gas flow rates over the cross-section of the furnace shaft and the depth of radial penetration of the gas flow into the material layer. Calculations of τ1 and τП were carried out in the following way: for τ1, the temperature range of the medium was chosen from 1300 to 250−300 °С, τox − the temperature range for the material was chosen from 1000 to 100 °С and the density of the product was taken into account at the degree of decomposition of limestone 98% (=1700 kg/m3). In the preheating zone, the limiting stage is the supply of heat from the gas to the lump material, and at the same time can be taken equal to ⁓400−450 kJ/(m2∙h∙К) and τ1 is estimated as 0.8÷1 hour. The total residence time of the material in the furnace (in the heating zone and in the firing zone) is estimated at 1.4÷1.5 hours. The average speed of material movement in the cylindrical part of the furnace is estimated as 0.004 m/s, which makes it possible to consider the filtering layer conditionally stationary. These characteristics affect the quality of limestone and the uniformity of limestone firing that was the basis for the design of roasting shaft kilns using gaseous fuel.

Authors: Salnyk Yurii , Volochiy Bohdan
Published: June 2021

Context. Objects of critical infrastructure require adequate security. The security systems for such objects have a specific requirements. Fulfilment of part of these requirements can provide by an unattended ground sensor complex which uses seismic sensors. The second part of the requirements can be performed by an unmanned aircraft complex. Therefore, it is seen as practical feasibility to combine these two complexes in one security system with three control zones. The first (Further) and second (Hither) control zones are served by an unattended ground sensor complex. The third control zone (intruder escort zone) is assigned on the data from the unattended ground sensor complex: the type of intruder, his speed and direction of movement. The unmanned aircraft complex is used to perform a security system task in the intruder's tracking area on command from the unattended ground sensor complex. You need to know two question answers to implement such a security system. First, what is the efficiency indicator value of the security system will ensure the combination of the existing complexes with their functionality indicators. And the second, what should be the functionality indicators requirements of these complexes in order for the security system to provide the required performance indicator value. Objective. Therefore, the goal of the article is to show the potential value of the efficiency index of the security system formed from the existing complexes, as well as to assess the possibility of increasing its efficiency. Methods. This goal is achieved by the stochastic model of functional behavior, which should reproduce all variants of the security system components reaction to the crossing of three control zones by intruders. Results. The main result is a discrete-continuous stochastic model of the functional behavior of the critical infrastructure object security system in the form of 76 Kolmogorov-Chapman differential equations system. The grade of the stochastic model adequacy makes it possible, in addition to the analysis tasks of the security system effectiveness, to solve the synthesis tasks of functionality indicators of the complex components that are integrated into the security system. Conclusions. Research was conducted have shown that it is impractical to create a security system based on existing unattended ground sensor complexes and unmanned aircraft systems for critical infrastructure objects because of the unacceptably low system efficiency. Based on the synthesis task solution, the functionality indicators values of the each complex components, in particular those that will provide the required value of the security system efficiency indicator, are presented. The stochastic model of the functional behavior of the security system can be used in the information technology of its design to find compromise solutions between different variants of composition, structure and functional behavior of the security system.

Published: June 2021

The ways of improving the mechanisms of information and analytical support of the command control system in the state of emergency are analyzed. The approach to the application of the ontology of the choice problem for decision-making in the field of law enforcement management using the procedure of integration of information resources based on the binary partial order relation is used. The purpose of the article is to increase the efficiency of decision-making in the management system of the military command in a state of emergency by applying the ontology of the choice problem based on a set of semantically significant results. Results of the research. Analysis and processing of large arrays of information in the field of military command management in a state of emergency should be carried out in an automated mode on the basis of a distributed software environment based on the principles of ontologies. Ontological systems, as a result of the inverse mapping of natural systems, provide the correct aggregation of various thematic processes through the formation of a structured set of information objects-concepts of the subject area, which are defined as a single type of data. The ontological representation of the contexts of units-concepts provides their integrated use in the process of solving complex tasks by the governing bodies of the command in a state of emergency. One of the constructive ways to integrate information resources as passive knowledge systems is to activate their concepts based on the process of forming thematic ontologies and combining these ontologies by building an ontology of the choice problem over them. The uniqueness of the ontology of the choice problem to any homotopy type allows to build the procedure of integration of information resources on the basis of a binary partial order relation. The partial order relation allows to reflect in an integrated way interaction of contexts of the notion-concepts defining subjects of information resources. The contradiction between the increase in the amount of information needed for decision-making in the field of management of interdepartmental critical systems and the constant requirement to reduce the time for its processing in the information-analytical systems has been resolved.

The work is devoted to the multiobjective task of scheduling, in which a given set of works must be performed by several performers of different productivity. A certain number of bonuses is accrued for the work performed by the respective executor, which depends on the time of work performance. The criteria for evaluating the schedule are the total time of all jobs and the amount of bonuses spent. In the research the main approaches to solving multiobjective optimization problems were analyzed, based on which the Pareto approach was chosen. The genetic algorithm was chosen as the algorithm. The purpose of this work is to increase the efficiency of solving multicriteria optimization problems by implementing a heuristic algorithm and increase its speed. The tasks of the work are to determine the advantages and disadvantages of the approaches used to solve multicriteria optimization problems, to develop a genetic algorithm for solving the multicriteria scheduling problem and to study its efficiency. Operators of the genetic algorithm have been developed, which take into account the peculiarities of the researched problem and allow to obtain Pareto solutions in the process of work. Due to the introduction of parallel calculations in the implementation of the genetic algorithm, it was possible to increase its speed compared to the conventional version. The developed algorithm can be used in solving the problem of optimal allocation of resources, which is part of the system of accrual of bonuses to employees.

An urgent issue of modern local conflicts is the substantiation of the ability of air defense units to carry out their immediate tasks of providing air cover for ground forces. The solution to this issue is especially relevant in local conflicts, when the space in which it is necessary to perform the assigned task is stretched in width and depth. The purpose of the article is to develop a model for evaluating the effectiveness of ground forces cover by air defense units in new positional areas, which have changed in size in width and depth. The article proposes a model that makes it possible to assess the effectiveness of covering weapons and military equipment and infrastructure of ground forces by air defense units. The model was developed using the theory of probability. Conclusions. The proposed model involves the choice of a typical composition of internal and external sources of radar information, the direction of data exchange, the composition of the tasks of data processing, the formation of recommendations on the composition of the air defense team and their management. The developed model helps the commander of the air defense unit to evaluate the options for his structure, choose rational ones, with the best cover efficiency, and helps him make the right decision to repel air strikes. The model is proposed to be used in decision-making systems to help the commander make the right decision to cover ground units from the air. The proposed model will also be effective in automated decision-making systems.

Authors: Андрусевич Володимир , Обод Іван
Published: June 2021

The paper pays attention to the consideration of the structure of user's information support of the airspace control system at the stage of primary information processing by the joined radar system. This system includes a primary and identification surveillance system, which allows considering the overall structure as a single synchronous network of surveillance information systems. Such a structure can be characterized by an overall integrated quality indicator of the information support of the airspace control system. Such a quality indicator can be the probability of information support, which is the product of the probabilities of correct detection of an air object by the primary radar and identification system on the basis of "friend-foe" and the probability of comparing the coordinate information of primary radar systems and identification systems. This approach allows changing the model of combining information for primary radar systems and identification systems so as to take into account the estimated coordinates of the air object by both information systems due to the weight combination of coordinates of air objects. The calculation of the coordinates of air objects according to the information of the primary radar systems and identification systems allows improving the quality of information support for decision makers in the air traffic control system.

The topic of the paper is determining the impact of an epidemic threat situation on the design of office space and office buildings. The types of actions taken to improve safety are: procedural actions, modifications of technical solutions: architectural and installation and remote work. Solutions in the field of office space architecture include: reducing the density of occupants, introducing partitions, eliminating multi-person offices, using materials that are easy to disinfect and clean, opening windows and installing personal protective equipment dispensers. The installation solutions include air quality improvement, filtration and disinfection systems as well as telecommunication installation systems supervising the use of the building. It can be expected that in the future, technical solutions will be introduced into the designs of buildings and office spaces, which will be a place for meetings, spontaneous interactions, mutual inspiration of employees and strengthening their identification with the employer whereas the ratio of office work places will be lower. The structure of the building is likely to change to a richer commertial part, a co-working part and flexible offices, and a traditional part of office space for lease, but as such office buildings will still be needed.

The direction of housing development results from changes in the spatial consciousness of the society. The article, based on historical studies of Russian housing, hypothesizes that the development of the geometry of living quarters is characterized by cyclical changes. The spatial image of living premises as the basis of its reproduction is influenced by informational factors: external – inherent in the global design technology existing at a certain historical time, and internal, arising from the experience gained as a result of local construction. Both information streams change the state of political awareness that determines the direction of structural changes in the physical environment until they are effectively used.

The share of various means of transport in travels within the city is not only a technological issue, but first and foremost a spatial issue. Walking and bicycle trips tend to be shorter both in terms of distance and time, compared to trips made by public transport or by car. Therefore, a question arises: how functions should be distributed of in the city to enable its inhabitants to use individual car transport as little as possible? The aim of the article is to discuss several concepts regarding walking, cycling and public transport distances and to confront these theories with data obtained in several European cities -Amsterdam, Berlin, Copenhagen, London, Paris, Warsaw and Vienna.

The article deals with the issue of the nature and quality of reviews of scientific publications in the research area of architecture and urban planning. The aim of the article is to indicate the unique character of the undertaken research topic, often implying unconventionally undertaken research methods. As a result, the proposals for extending the offer of publishing patterns are discussed, which could enable the presentation of research results in the discipline of architecture and urban planning. These present, in a way that goes beyond the schemas, issues from the border of exact, humanistic, natural, social and artistic sciences. The methods used allow for the characterization of selected scientific publications as well as scientific reviews.

Architects, as a professional group, publish articles in trade journals—dedicated to their profession—and some also publish in academic journals. There are several types of academic articles and each serves a different purpose. Each of these types has a specific layout, which should be adhered to. The author, while working on the material in the manuscript to be sent to an academic journal, should be aware of the type of paper they are writing and this should be stated in the abstract—the TYPE of paper, similarly to keywords. Upon the submission of an abstract and later the full text of the paper to the editorial office, the author accepts the terms and conditions presented by the academic journal. Along with the submission of an abstract, there begins the complex work of the journal’s editorial team on the final preparation of the manuscript for publication.

Aetobatus (Myliobatiformes: Aetobatidae) is a living genus of eagle rays that occurs in shallow-marine, tropical and subtropical environments of the Atlantic, Pacific, and Indian Oceans. Nowadays, Aetobatus does not inhabit the cool- to warm-temperate European and Mediterranean waters, though it is known from this broad region by virtue of several fossil teeth ranging chronostratigraphically from the lower Palaeogene to the upper Neogene. The present paper reports on a fossil aetobatid tooth discovered in mid-Pliocene (upper Zanclean to lower Piacenzian, 3.82-3.19 Ma) marine deposits exposed in the vicinities of Certaldo (Tuscany, Italy) and identified as belonging to †Aetobatus cf. cappettai. This specimen comprises the youngest occurrence of Aetobatus along the coasts of mainland Europe; furthermore, together with previous finds from roughly coeval deposits of Mallorca (Balearic Islands, Spain), it represents the most recent record of this genus in the whole Euro-Mediterranean region. In light of the environmental preferences of extant Aetobatus spp., our discovery suggests palaeoenvironmental conditions favourable to the persistence of tropical/subtropical taxa of "Miocene survivors" along the Pliocene coasts of Tuscany. In addition, it raises the question of whether or not the Messinian Salinity Crisis really resulted in the complete collapse of the Mediterranean marine biota and in the subsequent recolonisation of the Mediterranean Basin from the adjoining Atlantic waters and/or scattered marginal intrabasinal refugia at the beginning of the Pliocene. The possibility of Aetobatus recolonising the Mediterranean Sea through the Suez Canal in the near future is discussed.

Este trabalho tem como objetivo apresentar uma discussão acerca das principais teorias, presentes na Didática da Matemática (DM), originadas no cenário francês. Trata-se de um conjunto de embasamentos teóricos, provenientes da revisão de literatura de trabalhos científicos anteriores que, porventura debateram sobre o mesmo tema, tais como os de Almouloud (2007, 2019), Artigue (1990), Brousseau (1976, 2002,2008), Chevallard (1991) e Alves (2011, 2016), constituindo assim uma gama de conceitos inicias de uma futura pesquisa de mestrado. Tendo como aspecto central a interação entre professor, aluno e saber matemático, e com o amparo de uma contextualização histórico-conceitual, as teorias presentes neste artigo demarca elementos representativos que contribuíram para a organização e construção deste campo de estudo. Deste modo, os tópicos vindouros apresentam uma abordagem teórica sobre a transposição didática, contrato didático, obstáculos epistemológicos e didáticos, e, por fim, situação didática.
O uso da Didática Profissional na formação de professores de Matemática: o caso da competência diante do ensino remoto
Authors: Dos Santos Maria Graciene Moreira , Alves Francisco Régis Vieira , Gomes Cidrão Georgyana
Published: June 2021

A Didática Profissional surgiu na década de 90, emergido após um cenário de mudanças no quadro trabalhista pautado no taylorismo, tendo como uma das principais características em compreender o processo de desenvolvimento profissional in loco. Com isso, este trabalho, analisa a partir da Didática Profissional a atuação dos professores de matemática em formação continuada diante do cenário atual de ensino remoto, identificando as competências profissionais desenvolvidas diante do ensino on-line. Contudo, Pastré, Mayen e Vergnaud (2006), Pastré (2011), Alves (2019; 2020) são alguns autores que tomam destaque diante desta pesquisa, sendo especialistas na escrita científica sobre a Didática Profissional. O processo metodológico tem fundamentos qualitativos, inicialmente foi realizada uma revisão bibliográfica a respeito dos fundamentos da Didática Profissional, e em seguida a aplicação de um questionário por meio eletrônico no Google forms com determinado grupo de professores da pós-graduação do Instituto Federal de Educação, Ciência e Tecnologia do estado do Ceará, campus Juazeiro do Norte. Durante a análise dos dados, os professores demonstraram algumas habilidades adquiridas durante o ensino remoto, e uma aproximação com as tecnologias digitais. Por fim, os estudos francófonos acerca da educação e ensino, demonstram uma satisfação frente à formação docente.
