METHODS OF STUDYING THE SEMANTICS OF PROGRAMMING LANGUAGES BY THE STUDENTS OF PROFESSIONAL EDUCATION INSTITUTIONS
Authors: TKACHUK STANISLAV , MELNYK OLEKSII
Published: July 2023

The article shows that in institutions of professional (vocational and technical) education, the inclusion of a block of questions devoted to the semiotics of programming languages into the content of learning languages and programming methods will contribute to the successful implementation of the system of their fundamental training in the subject field «Information Technologies». The methodological system of education, built within the framework of the methodologicalical theory, helps students acquire knowledge and skills in the semiotics of programming languages. The main theoretical and methodological provisions are outlined, on the basis of which a methodical system of teaching the semiotics of programming languages ​​and a metamodel of the teaching method itself in the form of a methodical theory have been built. On the basis of the classification of models of syntax and semantics of programming languages, carried out to build a conceptual basis for the methodological theory of teaching semiotics of programming languages, there have been selected the following sections for teaching semiotics of programming languages: formal syntax of programming languages; meaningful operational semantics of programming languages; formal operational semantics of programming languages; formal deductive semantics of programming languages; denotational semantics of programming languages. At the stage of selecting the content of the elements of the model of the methodical system for teaching the semiotics of programming languages, the central place is occupied by the problem of setting learning goals, since the selection of the content of other elements is aimed at achieving the set goals. Semiotic educational models include a system of tasks, in which the subject area of activity is developed within the framework of specific teaching methods, which involve textual statements of educational problems or tasks. The goals and content of learning the semiotics of programming languages, largely influencing each other, determine the choice of teaching methods for the section in question. For example, when considering the last block of learning content, there has been chosen a simulation or social learning model, which provides for the student’s assimilation of new information, as well as attempts to get involved in the situation of solving professional tasks based on it.

Published: July 2023

The peculiarities of the implementation of the educational process in secondary and higher education institutions under martial law are characterized. The need to adapt educational content to modern realities is indicated. The relevance of the use of innovative means of training future specialists in technological education, as well as high school students in the lessons of labor training (technology) is substantiated. The potential possibilities of the QR-generator as an innovative means of educational activity of participants in the educational process of secondary and higher education institutions are outlined. The methodical aspects of its application in the process of creating a teacher’s (lecturer’s) V-card, as well as the project activities of future technological education specialists are determined. An experimental study of the effectiveness of the use of the QR-generator in the educational process of secondary and higher education institutions was conducted. The conclusions from the conducted research are substantiated: the use of the QR code generator in educational technological activities increases the interest of pupils and students in learning the educational material. It will also allow to increase the level of prestige of educational subjects of labor training and technologies in secondary education institutions, as well as increase the effectiveness of the educational process, mastering the strategy of project activity, independent choice of the mode of educational activity, organizational forms and methods of education. The option of replacing illustrative and explanatory teaching methods with a variety of different types of educational activities, focused on the active use of information and communication technologies as tools of cognition and self-cognition, tools of research, construction, measurement and formalization of knowledge is proposed.
Connecting the Equinoctial Elements and Rodrigues Parameters: A New Set of Elements
Authors: Peterson Joseph T. A. , Arya Vishala , Junkins John L.
Published: July 2023

A geometric interpretation of the equinoctial elements is given with a connection to orthogonal rotations and attitude dynamics in Euclidean 3-space. An identification is made between the equinoctial elements and classic Rodrigues parameters. A new set of equinoctial elements is developed using the modified Rodrigues parameters, thereby removing the coordinate singularity for retrograde equatorial orbits present in previous versions of these elements. A low-thrust trajectory optimization problem is set up using the new elements to numerically verify convergence for the two-point boundary problem, as compared to their predecessors.
Adaptive Neural-Network-Based Unscented Kalman Filter for Robust Pose Tracking of Noncooperative Spacecraft
Authors: Park Tae Ha , D’Amico Simone
Published: July 2023

This paper presents a neural-network-based unscented Kalman filter (UKF) to estimate and track the pose (i.e., position and orientation) of a known, noncooperative, tumbling target spacecraft in a close-proximity rendezvous scenario. The UKF estimates the target’s orbit and attitude relative to the servicer based on the pose information provided by a multitask convolutional neural network (CNN) from incoming monocular images of the target. To enable reliable tracking, the process noise covariance matrix of the UKF is tuned online using adaptive state noise compensation, which leverages a newly developed closed-form process noise model for relative attitude dynamics. This paper also introduces the Satellite Hardware-In-the-loop Rendezvous Trajectories (SHIRT) dataset to enable comprehensive analyses of the performance and robustness of the proposed pipeline. SHIRT comprises the labeled images of two representative rendezvous trajectories in a low Earth orbit created using both a graphics renderer and a robotic testbed. Specifically, the CNN is solely trained on synthetic data, whereas functionality and performance of the complete navigation pipeline are evaluated on real images from the robotic testbed. The proposed UKF is evaluated on SHIRT and is shown to have subdecimeter-level position and degree-level orientation errors at steady state.
Analysing the Lived Experiences of Undocumented and Unaccompanied Child Migrants from Zimbabwe to South Africa
Authors: Chiweshe Manase Kudzai
Published: July 2023

Zimbabwe’s socio-economic crisis post-2000 led to the emergence of new forms of livelihoods. Long- and short-term migration emerged as a survival strategy for over a million Zimbabweans who moved legally and illegally to countries such as South Africa, England, Botswana, Namibia, Canada and Australia. While migration in Zimbabwe has mainly been an adult pursuit, post-2000, there has been an increasing number of unaccompanied child migrants. Zimbabwean unaccompanied child migrants in South Africa provide important insights into how the socio-economic rights of children are central to understanding child migration. This article focuses on the lived experiences of undocumented and unaccompanied child migrants from Zimbabwe living in South Africa. It utilises a desk research approach to analyse how the socio-economic rights of child migrants are experienced in Zimbabwe and South Africa. Both states have failed to meet their national and international obligations to protect child migrants. The article highlights various forms of abuse undocumented child migrants from Zimbabwe experience in South Africa. The article concludes that both local and international law in South Africa fails to provide a balance between the competing interests of child protection and child autonomy.

Hepatitis E virus as a transfusion transmitted infection-current status
Authors: Ghosh Kanjaksha , Mandal Prakas Kumar , Ghosh Kinjalka
Published: July 2023

Objectives:

Hepatitis E virus (HEV) infection is growing worldwide and presents a new threat to the blood transfusion services across the world. The present review tries to explore how the transfusion medicine community is responding to the threat.

Materials and Methods:

The major papers and important case reports were culled from PubMed, Science Direct, Embase related to this infection, and transfusion medicine since 2005 were explored and relevant articles were discussed with emphasis on epidemiology, infection, prevalence in donor population, susceptible recipients, prevention, and future development.

Results:

There are eight genotypes of this virus with different host, transmission biology, and clinical infection. Chronic infections are more common with Genotype 3 and Genotype 4 which are prevalent in Europe and transmitted by pig and meats cooked from this animal. Genotype 5 and 6 has not yet been linked to human transmission. Genotype 1 and Genotype 2 cause epidemic form of this infection and are common in developing countries. Immunosuppressed and chronic liver disease patients get chronic or severe infection. Pregnant ladies develop fulminant hepatitis with high mortality. The virus is transmitted by blood products but severe infection is uncommon. Many European countries, USA, Canada are using Nucleic Acid Testing (NAT) based technology to screen their donors as Individual Donor-NAT or Minipool NAT with varying efficiency. Large part of the world as yet has not taken any active measure to contain this infection through transfusion. A vaccine is available, effective but is not widely used as more studies are needed. Cross immunity does happen between genotypes and presence of immunoglobulin G antibody in blood protects against serious infection. Alanine transaminase level corresponds with viremia in asymptomatic but infected individuals.

Conclusion:

The HEV is an emerging but important threat to transfusion medicine service. Important information regarding this infection is still lacking. However, there is a need to develop robust safety algorithm to counter this threat and make transfusion safer.

Сравнение оттисков печатей на буллах с городища Старая Ниса, древней столицы Парфии, и на буллах с соседних территорий, которые можно рассматривать как парфянскую периферию – городище Арташат в Армении, крепость Гёбеклы-депе в Маргиане (северо-восточная граница Парфии), городище Габала в Азербайджане – демонстрирует различное соотношение традиционных греко-римских сюжетов (античные боги и герои, портреты в греко-римской манере) и сюжетов иранских (царская охота, сцены инвеституры, всадник, венчаемый Никой, персонажи в иранских костюмах). В Армении преобладают греко-римские изображения, хотя присутствуют и иранские. Старая Ниса представляет в равной мере обе традиции, крепость Гёбеклы дает, за редким исключением, иранский материал. Соотношение античных и иранских сюжетов на буллах с городища Габала свидетельствует, пожалуй, о преобладании местной, восточной традиции, однако оттиски с античными сюжетами среди них явно присутствуют.

The comparison of seal impressions on the clay bullae from Old Nisa, the ancient capital of Parthia, and on the bullae from the neighbouring territories – the site of Artashat in Armenia, the fortress of Göbekly-depe in Margiana and the site of Gabala in Azerbaijan – demonstrates different proportions between traditional Greek and Roman images (gods and heroes and their attributes) and Iranian motifs (royal hunt, investiture, a warrior crowned by Nike, persons in Iranian garments). Hellenistic images predominate in Armenia, although Iranian-style ones are also present. Both traditions are represented in Old Nisa, whereas the fortress of Göbekly yields mostly Iranian material. The evidence from Gabala, though not plentiful, suggests that while Greek and Roman images were definitely in use there, the majority of the seals featured East Iranian motifs.

Published: July 2023

Low-affinity protein-ligand interactions are important for many biological processes, including cell communication, signal transduction, and immune responses. Structural characterization of these complexes is also critical for the development of new drugs through fragment-based drug discovery (FBDD), but is challenging due to the low-affinity of fragments for the binding site. Saturation transfer difference (STD) NMR spectroscopy has revolutionized the study of low-affinity receptor-ligand interactions enabling binding detection and structural characterization. However, the use of the STD NMR technique together with full relaxation matrix calculations for the validation of 3D structures of protein-ligand complexes remains a major milestone in the field. In this work, we present a new approach based on a reduced relaxation matrix that allows very fast 3D structure evaluation of lowaffinity protein-ligand complexes by STD NMR data and molecular dynamics simulations.

Multi-electron redox chemistry is traditionally a domain of transition metals which are well-known to show multiple valence states with a vast variation of physical and chemical properties. Redox-active organic molecules, on the other hand, usually present only two valence states. Herein we demonstrate the design and preparation of a very simple organic molecule benzo[1,2-c:3,4-c':5,6-c'']tris([1,2,5]thiadiazole) 2,2,5,5,8,8-hexaoxide (tripak) that shows unprecedently rich redox chemistry and is capable of accepting up to six electrons in five consecutive reduction steps. Tripak is a derivative of the thermodynamically unstable [6]oxocarbon C6O6, where all C=O groups were used to form three dioxothiadiazole rings. It is the first representative of the new poly(dioxothiadiazole) family of compounds comprising three dioxothiadiazole groups fused together to form a simple rigid highly symmetrical skeleton with a single benzenoid ring in the middle. The electron withdrawing character of the dioxothiadiazole rings is responsible for the reversible multi-electron redox behavior which enabled its isolation and complete structural and physicochemical characterization in five-out-of-six oxidation states: 0, -1, -2, -3 and -4. Depending on the number of electrons, the tripak system represents different types of aromaticity (non-aromatic, Hückel or Baird) and redox-related multifunctionality: tripak0 shows record-strong anion-π binding of halides which is comparable with the energy of coordination bonds, tripak1- and tripak3- are two very different S = 1/2 radical states with tripak1- exhibiting very long spin-spin relaxation time at room temperature placing it among the most promising molecular qubit candidates, tripak2- is a blue dye with strong red fluorescence and finally tripak4- is an open-shell singlet diradicaloid system with a singlet-triplet gap close to zero.

Статья посвящена химической модификации природного полимера хитозана с целью повышения его качества и пригодности для дальнейшего синтеза наночастиц и пленок. Были синтезированы образцы хитозана, очищенные гидроксидом натрия с последующим переосаждением, обладающие повышенной степенью деацетилирования и сниженной молекулярной массой. Также обработкой янтарной кислотой, цистеином, соляной кислотой получены растворимые при нейтральных значениях рН производные хитозана. Для каждого из синтезированных образцов были получены инфракрасные спектры диффузионного отражения на ИК-Фурье спектрометре IR Prestige-21 (Shimadzu, Япония), определены степень деацетилирования и молекулярная масса.

The nuclear envelope (NE) is a subdomain of the ER with prominent roles in nuclear organization, which are largely mediated by its distinctive protein composition. We developed methods to reveal low-abundance transmembrane (TM) proteins concentrated at the NE relative to the peripheral ER. Using label-free proteomics that compared isolated NEs with cytoplasmic membranes, we first identified proteins with apparent NE enrichment. In subsequent authentication, ectopically expressed candidates were analyzed by immunofluorescence microscopy to quantify their targeting to the NE in cultured cells. Ten proteins from a validation set were found to associate preferentially with the NE, including oxidoreductases, enzymes for lipid biosynthesis, and regulators of cell growth and survival. We determined that one of the validated candidates, the palmitoyltransferase Zdhhc6, modifies the NE oxidoreductase Tmx4 and thereby modulates its NE levels. This provides a functional rationale for the NE concentration of Zdhhc6. Overall, our methodology has revealed a group of previously unrecognized proteins concentrated at the NE and additional candidates. Future analysis of these can potentially unveil new mechanistic pathways associated with the NE.
Wear out effect for cutting element of milling machine on asphalt concrete cutting strength

Published: July 2023

Introduction. This article presents the results of a study of the wear out effect the carbide tip for the cutting element of a milling machine on the resulting cutting strength when milling asphalt concrete. The relevance of the work is due to insufficient information about the wear out effect on the strength of cutting resistance, and, consequently, it is not possible to predict changes in loads on the working body of milling machines during its operation with worn cutting elements.

Materials and methods. The experimental studies to determine the cutting resistance force that occurs during the milling of asphalt concrete with a maximum mineral aggregate size of 16 mm. used for the top layer of the coating and for roads with normal traffic conditions (A16vn), depending on the thickness of the chip being cut and the degree (percentage) of wear of the cutting element were carried out. To conduct the study, a pendulum stand, which is most suitable for studying the interaction of a single cutting element of a road milling cutter with asphalt concrete, was used.

Results. As a result of experimental studies, it was possible to obtain the data allowing a reasonable approach to the choice of the interval of replacement of cutting elements during the operation of milling equipment, which, in future, will lead to an increase in the productivity of equipment and its service life. The achieved results make it possible to adjust previously obtained mathematical models and calculation methods of milling machines, taking into account the degree (percentage) of wear of cutting elements.

Discussion and conclusions. The conducted studies make possible to determine the dependence of the cutting strength on the percentage of wear of the cutting element and the thickness of the chip being cut. At the same time, it can be concluded that in practice it is necessary to set additional safety margins when designing elements of a milling machine, taking into account the wear of the cutting element.
What Is the Point of Nondomination?
Authors: Cass Devon
Published: July 2023

This paper examines the following distinctive republican claims: (1) goodwill and virtuous self-restraint are insufficient to realize freedom; and (2) suitable law is constitutive of freedom. In the contemporary literature, these claims are commonly defended in connection with the conception of freedom as nondomination. This account, however, is often rejected on the grounds that freedom as nondomination is moralized and impossible to realize. In response, I propose that the point of protecting people from domination is better understood not as realizing freedom, but instead as giving persons a civic status as equals. Giving persons a civic status as equals, I claim, realizes an important form of social or 'relational' equality, and I distinguish this aim from giving persons a 'status as nondominated’, as some republicans require. I argue that this account vindicates alternative claims about the insufficiency of goodwill and constitutive importance of suitable law—understood in terms of equality rather than freedom—while avoiding the moralization and impossibility objections. I conclude by suggesting some further advantages of the proposed account versus the standard republican view.
New digital signature scheme based on MDLP and multinacci matrices
Authors: Manju Sanghi
Published: July 2023

A new digital signature scheme based on Matrices Discrete Logarithm Problem (MDLP) and generalized Fibonacci or Multinacci matrices is proposed. The security of the scheme is based on the difficulty of solving the Discrete Logarithm Problem (DLP) in matrices. MDLP is a new one-way function based on matrices that provides the same security as the DLP. The use of matrices increases the complexity of the scheme, as it involves matrix exponentiation rather than integers. In the proposed scheme, the signer uses a Multinacci matrix Fkn to generate the signature and an inverse Multinacci matrix Fn-k to verify it. The computational complexity and security of the scheme are also discussed.
