Recently, we can observe an increased interest in research on the history of the former Polish-Lithuanian Commonwealth based on the analysis of Western European archival resources. They present the image of Poland and Lithuania from a different point of view, which provides an interesting cognitive perspective and an opportunity to distance oneself from one’s own historiographical opinions. This is because facts that are commonly known but seen from a different, external perspective often acquire a new and valuable overtone. During the research in the National Archives and the British Library, we can find a large number of sources concerning the history of the former Polish-Lithuanian Commonwealth, which results from the active functioning of the Polish-Lithuanian state in the political struggles in Central and Eastern Europe, which was taken into account in diplomatic games in the west of the Old Continent. At the forefront of such documents are diplomatic correspondence, political writings, diaries of the Parliament, complete or partial. This group also includes instructions and accounts of local councils. Sometimes in the course of scientific research it is possible to come across manuscript documents completely unknown to Polish historiography, which either supplement the already known facts or present them in a slightly different way. This type of material is the instruction of the local council of the Poznań Voivodship “Points de l’instruction que la Province de la Grande Pologne a donnée à ses Députés, ou Nonces pour la Diète prochain” from 1701 and “Relation de ce qui s’est passé à la Diétine de la Grande Pologne à Szroda par rapport aux Dissidents” from 1735. The first manuscript concerns the local council of the Poznań and Kalisz voivodships, which was break off, but the draft instruction was made public. On the other hand, the instruction found in London is slightly different from that known from domestic research, but the reasons for this cannot be resolved at present. As far as the latter document is concerned, i.e. the account of the 1735 local council, although the instruction itself is known, we do not know much about the course of the congress, especially about the relations between dissidents and Catholics during the local council. The found manuscript explains this in some way.

The period in Danish history which began with the accession of power by Valdemar I in 1157 and ended with the death of his youngest son, Valdemar II (1241), known by posterity as the Victorious or the Lawgiver, is considered in Danish historiography as a time of significant social, political and legal changes. It is sometimes even named as the golden period of the Kingdom’s history in the Middle Ages, the so-called “Valdemar Era”. After years of internal struggles for power, real feudal fragmentation, and recognition of the emperor’s fief sovereignty, the nearly 100-year reign of Valdemar I and his two sons brought a re-consolidation of the state that included an expansion of royal authority, including the legislative powers of the rulers. This process was accompanied by cooperation between the state and the Church, whose support and approval led not only to a series of territorial conquests, the ordering of the treasury and the administrative apparatus, but also to the writing of the laws in force. It should be noted that beginning with the issuance of King Canute’s Law of Murder in 1200, the monarch begins to act as an independent legislator, which, given the customary legislative powers vested in the district councils (ting), is a significant innovation. As a culmination of the increased legislative activity of the rulers of the „Valdemar Era”, in 1241, the first Danish law on the Jutland district, Jyske Lov, was „given” with royal sanction. This law is preceded by a prologue, which can be regarded as a sui generis fundamental statute indicating, among other things, the scope of the monarch’s rights and duties, including the king’s legislative powers. The analysis of selected royal decrees from the first half of the 13th century, including especially the prologue to Jyske Lov, will allow, taking into account the political background, to present the scope of royal authority of the rulers of the «Valdemar Era»”, with particular emphasis on the monarch’s legislative powers.
Polycystic ovary syndrome (PCOS): international collaboration to translate evidence and guide future research

Published: March 2023

Polycystic ovary syndrome (PCOS) affects 8–13% of reproductive-aged women, impacts biopsychosocial factors and creates a significant health-related economic burden across the reproductive, metabolic and psychological spectrum of complications. Despite being a heterogenous condition, recent genomic studies indicate that PCOS, regardless of diagnostic criteria and clinical features, shares similar underlying biologic mechanisms. However, recent advances have shown that clinical reproductive and diagnostic features are poorly correlated to genotypes and do not represent true phenotypes. Until we have a better understanding of genetic and epigenetic influences on PCOS and long-term outcomes, targeted treatment is limited.

In the interim, a unified approach to integrate evidence, optimise management and guide future research in PCOS is necessary. This has motivated an international collaboration to develop an International Evidence-Based PCOS Guideline to improve health outcomes in women with PCOS. Dissemination and translation of the guideline into health policy and clinical practice are crucial steps to close the knowledge–-practice gap, guide future research and enhance positive impact on the health of women with PCOS.

Here, we review the (i) understanding of aetiology and genetics of PCOS; (ii) development and translation efforts of the 2018 International Evidence-based PCOS Guideline; (iii) current progress and plans for the guideline update, including the involvement of an early career researcher network to assist with evidence synthesis and (iv) the opportunity to target and guide future research for PCOS.
Tracking guided actions recognition for cows
Authors: Liang Yun , Chen Xiaoming
Published: March 2023

Background

Cows actions are important factors of cows health and their well‐being. By monitoring the individual cows actions, we prevent cows diseases and realize modern precision cows rearing. However, traditional cows actions monitoring is usually conducted through video recording or direct visual observation, which is time‐consuming and laborious, and often lead to misjudgement due to the subjective consciousness or negligence.

Methods

This paper proposes a method of cows actions recognition based on tracked trajectories to automatically recognize and evaluate the actions of cows. First, we construct a dataset including 60 videos to describe the popular actions existing in the daily life of cows, providing the basic data for designing our actions recognition method. Second, eight famous trackers are used to track and obtain temporal and spatial information of targets. Third, after studying and analysing the tracked trajectories of different actions about cows, a rigorous and effective constraint method is designed to realize actions recognition by us.

Results

Many experiments demonstrate that our method of actions recognition performs favourably in detecting the actions of cows, and the proposed dataset basically satisfies the actions evaluation for farmers.

Conclusion

The proposed tracking guided actions recognition provides a feasible way to maintain and promote cows health and welfare.
Distal nucleotides affect the rate of stop codon read‐through
Authors: Escobar Luciana I. , Alonso Andres M. , Ronderos Jorge R. , Diambra Luis
Published: March 2023

Background

A key step in gene expression is the recognition of the stop codon to terminate translation at the correct position. However, it has been observed that ribosomes can misinterpret the stop codon and continue the translation in the 3′UTR region. This phenomenon is called stop codon read‐through (SCR). It has been suggested that these events would occur on a programmed basis, but the underlying mechanisms are still not well understood.

Methods

Here, we present a strategy for the comprehensive identification of SCR events in the Drosophila melanogaster transcriptome by evaluating the ribosomal density profiles. The associated ribosomal leak rate was estimated for every event identified. A statistical characterization of the frequency of nucleotide use in the proximal region to the stop codon in the sequences associated to SCR events was performed.

Results

The results show that the nucleotide usage pattern in transcripts with the UGA codon is different from the pattern for those transcripts ending in the UAA codon, suggesting the existence of at least two mechanisms that could alter the translational termination process. Furthermore, a linear regression models for each of the three stop codons was developed, and we show that the models using the nucleotides at informative positions outperforms those models that consider the entire sequence context to the stop codon.

Conclusions

We report that distal nucleotides can affect the SCR rate in a stop‐codon dependent manner.
Effect of freezing temperature and stacking sequence on the mechanical properties of hybrid fibre metal laminates made with carbon, flax, and sugar palm fibres

Published: March 2023

Fibre metal laminates (FML) were reinforced with flax and sugar palm fibres in different stacking sequences and exposed to freezing conditions. The effects on the mechanical properties were explored. Both the stacking sequence and freezing condition affected the mechanical properties. The FML with flax fibres showed the highest strength and modulus under tension and bending, while the FML with sugar palm fibres showed the lowest strength and modulus. The FML with flax fibres experienced a fibre bridging effect and showed promising behaviour for aircraft applications by sustaining nearly 40000 cycles of fatigue load. Decreases in the strength, modulus, and fatigue life occurred when the FML specimens were exposed to freezing conditions. Micrographs from the tensile fractured specimens indicated delamination, fibre splitting, fibre breakage, and fibre/matrix de-bonding as the failure pattern for the pristine and conditioned laminates.

Published: March 2023

The stability of cellulase in the presence of ionic liquids (ILs) is pivotal for the in situ saccharification of cellulose. This study investigated the effects of various carbon sources on the cellulase production of Paenibacillus sp. LLZ1. The results showed that the activities of both the total cellulase and endoglucanase induced by microcrystalline cellulose were higher than those induced by other examined carbon sources. Simultaneously, a zymography analysis revealed the presence of seven protein bands (carboxymethylcelluloses 3, 4 and 6 through 10) with endoglucanase activity when MCC was used as the carbon source for culturing Paenibacillus sp. LLZ1. The endoglucanase induced by MCC showed stability in a 25% solids 1-ethyl-3-methylimidazolium diethylphosphate ([Emim]DEP) solution. Furthermore, the addition of metal ions and surfactants increased the endoglucanase activity in the [Emim]DEP solution, where 0.5 mM of Fe2+ and 0.1% of polysorbate (PSM 60) led to 11% and 29% increases in filter paper activity, respectively. Finally, three types of biomass (MCC, bagasse cellulose, and bagasse) were used as raw materials for in situ enzymatic hydrolysis when involved 5% [Emim]DEP and 0.1% polyoxyethylene (60) sorbitan monostearate (PSM 60). Fourier-transform infrared spectroscopy and specific surface area measurements were used to explain the effects of PSM 60 on the hydrolysis efficiency of these three biomasses.

Published: March 2023

The inclusion of old newspaper as reinforcement in composites promotes the use of environmentally friendly materials, reduces landfilling, decreases chemical treatments to bleach the recycled paper, and provides alternatives to glass fiber. While there are studies on the tensile strength and stiffness of old newspaper reinforced materials, there is a lack of analysis of their flexural properties. Considering that bending loads are very common, the flexural stiffness of the materials must be examined prior to industrial use. In this study, the flexural moduli of composites made from old newspaper fibers and polypropylene were compared with other composites. The composites showed moduli ranging from 2.1 to 4.1 GPa, and a composite with 50% newspaper content had a flexural modulus comparable to 10% glass fiber composite. These values allow an industrial use of the composites for semi-structural purposes. A method to assess the intrinsic flexural modulus of the reinforcements was presented and evaluated against other micromechanics models. The value of the efficiency factors and a mean orientation angle were also obtained.

Published: March 2023

Wood bark is a residue of forestry production that is used as a fuel source. The chemical composition of tree bark is similar to that of the harvested wood, and it contains a variety of useful compounds. To determine the chemical composition and antioxidant activities of different barks, fir (Abies nordmanniana), beech (Fagus orientalis), pine (Pinus sylvestris), poplar (Populus alba), and oak (Quercus robur) barks were selected because they are used for industrial purposes in Turkey. The dried bark powders were extracted using a 65:35 methanol-water mixture (v/v) to determine the total phenolic content, the flavonoid content, and the antioxidant properties (2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), metal chelating, and H2O2 scavenging). The flavonoid components were analyzed by high performance liquid chromatography (HPLC) and extracted by hexane to analyze the volatile components by gas chromatography-mass spectrometry (GC-MS). The poplar bark extracts had the highest total phenolic content, highest total flavonoid content, and highest antioxidant content. The poplar bark extracts were rich in myricetin (87.761 mg/L), which is a flavonoid with rich antioxidant properties. The presence of valuable extracts suggests that barks may have uses as valuable raw materials for chemical applications such as cosmetics, perfumes, and food preservatives.
Microbial community in ethanol-methane coupling fermentation treating food waste

Published: March 2023

The microbial communities in ethanol-methane coupling fermentation reactors were studied. The community structure variation was monitored at the genus and phylum levels using PowerSoil® DNA Isolation Kit with 16S ribosomal RNA (16S rRNA). The distribution of microbial communities in the ethanol reactor was higher than the methane reactor at the phylum and genus level, indicating the influence of coupling fermentation. Clostridia (hydrogen producer) was the dominant species throughout the process at genus and phylum levels. This result indicates the efficient degradation of organic acids. In addition, Archaea methanogen species (aceticlastic methanogens) utilize both acetate and hydrogen to produce methane. The dominance of Methanosaeta rather than Methanosarsina in the anaerobic digestion reactor (R1) of coupling fermentation added further valuable information on food waste treatment. Moreover, lactic acid bacteria species (Lactococcus) was dominant in the ethanol reactor (R2), suggesting the efficient conversion of food waste to lactic acid, which could continue its conversion to ethanol. Interestingly, the high amount of ammonia, salts, and volatile fatty acids (VFAs) (including high acetate) could promote the SAO pathway in the coupling fermentation system.

Published: March 2023

Vessel and fiber properties, diameter growth, and chemical compositions were investigated for transgenic Populus trichocarpa (black cottonwood) trees harvested after six months of growth in a greenhouse. Genetic modifications were cinnamyl alcohol dehydrogenase (CAD), cinnamate 3-hydroxylase (C3H), or cinnamate 4-hydroxylase (C4H), which resulted in modified lignin composition or content, and changed the syringyl-to-guaiacyl ratio. Comparing the genetic groups to the wild-type as the control, trees with reduced lignin content showed different results for vessel and fiber properties measured. Genetic groups with reduced PtrC3H3 and PtrC4H1&2 (with lower lignin content and higher S/G ratio than the control) exhibited splitting perpendicular to the rays, yet had the same fiber lumen diameter and the same fiber cell wall thickness as the control. Changes in lignin structure from modifications to PtrCAD resulted in reductions to the number of vessels, increases in vessel and fiber diameters, and had no consistent impact on stem diameter.

Published: March 2023

Judicial utilization of various low-cost agro-industrial wastes and optimization of various process parameters can reduce production costs of enzymes. Wheat bran was found to be the best carbon source among various agro-industrial wastes explored for Penicillium citrinum NCIM-1398. Additionally, ammonium sulphate was found as the optimum nitrogen source at moisture content 70%, pH 5.5, and temperature 30 °C for enzyme production. The maximal enzyme activities of endo β-1,4-glucanase, xylanase, FPase, and amylase were 21.0 IU/gds, 3140 IU/gds, 3.59 FPU/gds, and 73.4 IU/gds, respectively. Bio-deinking of mixed office waste paper improved the pulp brightness by 9.5%, and the effective residual ink concentration were decreased by 26.3% in comparison to MOW after pulping. Similarly, dirt counts were reduced from 4880 to1360 ppm at an enzyme dose of 6.0 IU/g compared to deinking without enzyme. The strength properties of enzymatically deinked pulp such as tear index, tensile index, and burst index increased by 6.92%, 11.31%, and 7.61%, respectively, compared with the control.
Cellulose nanocrystals for wrinkled fabric
Authors: Lu Xiaomin
Published: March 2023

Although wrinkling is not appreciated in some of its manifestations, there are other instances for which it is essential to study and comprehend various physical phenomena related to wrinkling. Cellulose nanocrystals (CNCs) have some excellent intrinsic properties, i.e., high aspect ratio, percolation function, and good mechanical strength that have potential to affect wrinkling. Since the production period of bacterial cellulose is longer, it is efficient to use CNC as a substitute for bacterial cellulose in such applications. The network structure of bacterial cellulose can be mimicked by CNC fabric, which comprises several wrinkled CNC layers.

Published: March 2023

Thermogravimetric combustion characteristics of ginkgo leaves (GK), pine needles (PN), corn straw (CS), aspen leaves (AS), and white poplar leaves (WP) were studied. Results showed that the combustion of selected samples consisted of at least two weight loss stages. Besides, characteristic temperatures lagged towards high temperature zones under high heating rate, which was considered as the effect of insufficient transfer of heat. The combustion of volatile compounds and char from PN and CS was isolated under high heating rate and consequently the exothermic rate around 300 °C was intensified and the exothermic rate over 400 °C was decreased, while the maximum heat release rates of GK, AS, and WP were transferred into high temperature zones with the increasing of heating rate. The average activation energy of PN and CS was high though their combustion completed at a lower temperature, which was possibly due to the low average energy of molecules in samples in low temperature environment. The aromaticity, degree of condensation, CH2/CH3, and structure parameters of oxygen-containing functional groups were calculated according to the peak areas derived from the convolution of FTIR spectra. These parameters explained the discrepancy in both reactivity and exothermic behaviors of biomass samples during combustion.
An Investigation of the Influence of Economic Growth on Taxes in Lithuania
Authors: Ulvidienė Erstida , Meškauskaitė Irma , Stavytskyy Andriy , Giedraitis Vincentas Rolandas
Published: March 2023

The level of economic interstate competition has been growing significantly in recent decades. Countries are constantly trying to apply lower tax rates to attract large businesses to their territory. They are also trying to improve the efficiency of tax collection on their area of jurisdiction. The paper examines how economic growth affects Lithuania’s tax collections. Based on quarterly data of the 2002–2022 period, ARDL models for the main types of taxes were considered. We find that for all types of taxes, the models have the same structure, which allows comparing the impact of gross domestic product on tax collections both in the short term and in the long term. Analysis showed that the largest reserves are in the corporate sector, where the growth in tax revenues exceeds gross domestic product growth by 115%. The long-term effect for general taxes is almost 19% higher than the growth of the tax base, that is, the Lithuanian economy as a whole has a tendency for a reduction of the shadow economy, which means that there are significant opportunities for further growth.

On the Issue of Onomastics Rendering in Literary Translation
Authors: Lebovics Viktória
Published: March 2023

The article is dedicated to the problem of rendering of eloquent proper names in the translations of fiction writing. Attention is paid to the Hungarian and English translations of The Black Council historical novel by Panteleimon Kulish. The author has informed the editor of the magazine Moskvityanin of M. Pogodin on October 15, 1843. Kulish promises to create a whole gang of Cossacks in the novel, who receive eloquent nominations with interesting, diverse, associative characterization of the heroes encoded in them. In literary translation one can find relatively few such examples when speaking proper names are translated and not transmitted by transcription or transliteration. Many researchers consider the translation of speaking names to be impossible mission or super task. Ukrainian literature is extremely rich in works, the literary and onomastic analysis of which will certainly lead to new explanations and open new nuances in their interpretation. The examples of onyms rendering in the Hungarian translation, created by Anna Bojtár in 1978, submitted in the article, are the evidences of the fact that in many cases the semantic and associative meanings of onyms are lost, and the translator finds the appropriate solution when translating them only in some cases. The decisions of Yurii Stepan Nestor Lutskyi and his wife Moira in the English abridged translation of the novel, created almost at the same time, in 1973, are not much different. Nowadays scholars pay much more attention to the problems of translation of literary onomastics. More and more often there are the proposals to use the exact, adequate, appropriate, apt equivalent of eloquent names in the target language along with the recognition of their partial or complete untranslatability. Various possibilities of this issue solving can be found in scientific articles devoted to the translation of eloquent proper names of literary works. In reality, the choice of one or another variant of reproduction of eloquent proper names in the translation is motivated by various grammatical, lexical, semantic, connotative, culturological, ethnic, historical, pragmatic and other factors, among which the subjective desires of translators are also significant.
Polyphonism of Narrative in Documentary Cine-Text (Exemplified by the Poeta Maximus Film)
Authors: Hanzha Anhelina
Published: March 2023

Narrative in the film text is considered as a story on interconnected events occurring within specific space-time frames involving the author, narrator and characters. The intermedial nature of documentary filmmaking complicates its analysis in the coordinates of any research paradigms. However, polyphonism as the means of creating an integral idea on a cultural product should be singled out among the universal categories. The specific character of the polyphonic narration in the biographical portrait film consists in the actualization of the plot-creating motif of memory, in particular, the creation of a common memory on the hero’s life. Compositional and plot schematicity is actually the pragmatic aspect of using a polyphonic narrative. It is convenient technologically for the authors of films, especially in cyclical documentary TV projects, to adhere to the developed narrative scheme of the screen story. This process of production/consumption of media products belongs to the clichéd forms of communication. The use of polyphony has become a part of the format for some documentary cycles and their regular viewers habitually read such an audiovisual polyphonic narrative. This makes it possible to be adjusted easily to the perception of a stereoscopic picture of events, a dimensional presentation of the story of the hero of a biographical or historical documentary. The authoress’s vision of the realization of the polyphonism of the film narrative in the documentary Poeta Maximus (2008) from the series Game of Fate is submitted in the article. It is concluded that there is a certain plot-compositional scheme of organization of audiovisual polyphonic narrative in the serial. Transposition (transition from the direct speech of the presenter in the picture area to off-screen commenting), imposition (simultaneous use of the chronicle of the epoch with off-screen reading of an excerpt from the artistic text), combination (simultaneous use of photographs and video fragments on the screen) are fixed among the specific figures of the screen narration in the analyzed documentary. The event analysis of the Poeta Maximus film (2008) has made it possible to draw a conclusion about the significant event saturation and melodramatic motifs of the film.
Create in Me a Pure Heart, O God, And Renew a Steadfast Spirit within Me: On Some New Details of Creative Biographies of Sisters Olena and Olha Kulchytska (From Archival Materials)
Authors: Storchai Oksana
Published: March 2023

The article’s purpose is to publish interesting and significant archival materials, introduced into scientific circulation for the first time, namely: Biographical Data, Recorded from O. L. Kulchytska in September 1–3 1947 in the Sanatorium “Syniak” in Transcarpathia; Olena Kulchytska’s Autobiography of the 1940s old and an excerpt from a S. Butnyk-Siverskyi’s archival encyclopedic entry about his participation in Olena Kulchytska’s exhibitions up to and including 1947, accompanied by an introductory article and commentary. These archival documents will be interesting and useful in further research of creative biographies of the mistresses. The materials are stored at the Department of Visual and Applied Arts of the M. Rylskyi Institute of Art Studies, Folkloristics and Ethnology (National Academy of Sciences of Ukraine) and are published with keeping to authorial style, spelling, and punctuation with minor correcting. The creation of the sisters Olena Lvivna Kulchytska (1877–1967) and Olha-Melaniia Lvivna (1873–1940) Kulchytska occupies a prominent, significant place in the history of domestic art and organically fits into the context of European art. Natural talent, intelligence, brilliant knowledge of their craft, artistic taste, ability to emanate their own refined and unique world, their attitudes to art, dignity of soul and intentions – these are the features that were inherent in both sisters. The range of Olena Kulchytska’s creative heritage is wide and well-known among specialists, educated public, and admirers of fine arts. The artist successfully worked in various kinds of art: graphic art, painting, and applied arts. A gifted draftsman, watercolourist, aquafortist, and illustrator, in particular of children’s books, it is she who is associated with the revival of woodcutting and linocutting techniques in domestic art. Olena Kulchytska worked in the portraiture, genre painting, landscape painting, as well as in the genre of religious painting (she created a unique iconostasis); she was engaged in art weaving, modelling and designing of clothes, furniture, and architectural décor. In addition, she made sketches for ceramics and carpets. Known for her wonderful enamels, the mistress also worked in the fields of metal, small-scale sculpture, and jewellery. Olena Kulchytska devoted a lot of time to teaching and ethnography. Her intense exhibition activity is also impressive. Olha Kulchytska is a renowned mistress of decorative and applied arts, a carpet weaver; she was also engaged in pedagogical practice. Together with her sister, she created distinguished works of carpet art. Certainly, the archival materials now published should greatly complement creative biographies of the mistresses, mostly Olena Kulchytska, with new details.

Authors: Kantor Vitaly Z. , Proekt Yuliya L. , Kondrakova Irina E. , Litovchenko Olga V. , Zalautdinova Svetlana E.
Published: March 2023

Introduction. The aim of this paper was to look into the status of competence-based support for the inclusive education of children with disabilities from the standpoint of the unity of the competence-based approach to the preparation and professional activity of a teacher at an inclusive educational organization. Its relevance is defined by the need to determine the level of formation of inclusive competence of teachers in its direct correlation with the competence models embedded in the programs of inclusive-oriented university’s training of teachers.
Materials and Methods. The study involved 1 340 teachers working in inclusive educational organizations of general and additional education. They do not have university training in the field of defectology. The diagnostic and methodological basis for assessing the level of formation of inclusive professional competencies of a teacher was the authors-developed test that combined test tasks to identify the readiness of teachers to implement the right professional actions and decisions in conditions of inclusion.
Results. The results obtained indicate the imbalance in the formation of the key components of the professional competencies of teachers for inclusive education. Teachers have the most pronounced inclusive competencies in the field of individual or joint support with other specialists of a child with disabilities in the educational process and the organization of an individual learning route for him/her. The least pronounced component of inclusive professional competencies is the knowledge about development of children with disabilities. The success of solving situational problems is mediated by the nature of teachersʼ activities and their inclusive practice experience.
Discussion and Conclusion. The research materials may be in demand when designing training programs, professional retraining and advanced training of teachers of inclusive educational organizations, as well as in the framework of express diagnostics of the level of formation of inclusive competencies of teachers.
Exact Solutions of One Nonlinear Countable-Dimensional System of Integro-Differential Equations
Authors: Rassadin Alexander E.
Published: March 2023

In the present paper, a nonlinear countable-dimensional system of integrodifferential equations is investigated, whose vector of unknowns is a countable set of functions of two variables. These variables are interpreted as spatial coordinate and time. The nonlinearity of this system is constructed from two simultaneous convolutions: first convolution is in the sense of functional analysis and the second one is in the sense of linear space of double-sided sequences. The initial condition for this system is a doublesided sequence of functions of one variable defined on the entire real axis. The system itself can be written as a single abstract equation in the linear space of double-sided sequences. As the system may be resolved with respect to the time derivative, it may be presented as a dynamical system. The solution of this abstract equation can be interpreted as an approximation of the solution of a nonlinear integro-differential equation, whose unknown function depends not only on time, but also on two spatial variables. General representation for exact solution of system under study is obtained in the paper. Also two kinds of particular examples of exact solutions are presented. The first demonstrates oscillatory spatio-temporal behavior, and the second one shows monotone in time behavior. In the paper typical graphs of the first components of these solutions are plotted. Moreover, it is demonstrated that using some procedure one can generate countable set of new exact system’s solutions from previously found solutions. From radio engineering point of view this procedure just coincides with procedure of upsampling in digital signal processing.
Methods of numerical analysis for some integral dynamical systems with delay arguments
Authors: Tynda Aleksandr N.
Published: March 2023

The aim of this work is to construct direct and iterative numerical methods for solving functional equations with hereditary components. Such equations are a convenient tool for modeling dynamical systems. In particular, they are used in population models structured by age with a finite life span. Models based on integro-differential and integral equations with various kinds of delay arguments are considered. For nonlinear equations, the operators are linearized according to the modified Newton-Kantorovich scheme. Direct quadrature and simple iteration methods are used to discretize linear equations. These methods are constructed in the paper: an iterative method for solving a nonlinear integro-differential equation on the semiaxis (−∞,0]
, a direct method for solving the signal recovery problem, and iterative methods for solving a nonlinear Volterra integral equation with a constant delay. Special quadrature formulas based on orthogonal Lagger polynomials are used to approximate improper integrals on the semiaxis. The results of numerical experiments confirm the convergence of suggested methods. The proposed approaches can also be applied to other classes of nonlinear equations with delays.

Se han publicado muchas investigaciones sobre temas que involucran a universitarios, principalmente de carreras sanitarias, relacionadas con la automedicación. Sin embargo, en Argentina, estas son escasas o de algunos años de antigüedad. Por esta razón, el objetivo de este estudio es describir la prevalencia de la automedicación en los estudiantes de las carreras de la Universidad Católica de Cuyo en San Luis, Argentina, durante diciembre del 2021. Se estudiaron los alumnos regulares de las carreras pertenecientes a las facultades de la Universidad, que decidieron contestar la encuesta enviada a sus correos institucionales a partir de Google Forms. La población fue de 209 estudiantes, de la cual el 84 % fueron mujeres con un promedio de edad de 23 años. El 42 % pertenece a la carrera de Medicina y un 24 % es de primer año. Asimismo, 121 alumnos consumieron algún tipo de fármaco sin consentimiento de un profesional sanitario. El principal motivo del consumo fue porque habían aprendido previamente la utilidad del medicamento, el cual fue adquirido en su mayor parte en farmacias, basándose en consejos previos de médicos. Los fármacos más usados fueron los analgésicos, principalmente para aliviar el dolor de cabeza, los cuales lograron resolver la causa. El 83 % no sufrió ninguna consecuencia. Con respecto al consumo de alcohol junto con fármacos o a la modificación de tratamientos ya establecidos, la mayoría reconoció no hacerlo. En conclusión, según los resultados se logró observar la prevalencia de la automedicación en estudiantes universitarios de San Luis, Argentina.

El dolor neuropático surge de una lesión nerviosa que altera principalmente el sistema somato sensorial. Al producirse un daño en un nervio, se generan descargas continuas de las neuronas nociceptivas que conducen a un estado de hiperexcitabilidad el cual se constata por un incremento de la actividad espontánea, una reducción del umbral de excitación y una ampliación de receptividad para otros estímulos de naturaleza no dolorosa. Este dolor se caracteriza por ser una sensación intensa, quemante y de carácter crónico. Actualmente, los antidepresivos tricíclicos y los inhibidores duales de la recaptura de serotonina y norepinefrina se encuentran en la primera línea de tratamiento. Sin embargo, estos tienen una eficacia modesta y, a menudo, causan efectos adversos molestos como mareos, náuseas, somnolencia y dolor de cabeza. Ante la alta prevalencia de este tipo de dolor y su impacto, se realiza la presente revisión bibliográfica la cual mediante una búsqueda sistematizada identificó los principales artículos de revisión relacionados en el periodo comprendido del 2015 al 2021 y  proporciona los aspectos fundamentales de la patogénesis para una mejor comprensión del mecanismo de acción de los medicamentos utilizados en el tratamiento de este tipo de dolor. Así como otras posibles dianas terapéuticas, principales relaciones de la estructura química con la actividad biológica de los antidepresivos y terapias en investigación para el abordaje del dolor neuropático.

Purpose - to analyze the effectiveness of the timely appointment of pathogenetically justified secondary prevention in a patient with a burdened thrombotic and obstetric anamnesis based on the assessment of the course of pregnancy and the postpartum period in this woman. Clinical case. A woman with fetal loss syndrome and recurrent venous thrombosis applied for a consultation to plan pregnancy. The examination revealed a homozygous polymorphism of the F2-prothrombin gene (-20210 G>A), a decrease in protein S activity to the level of 35%, which indicated an extremely high risk of thromboembolic complications. Pregnancy occurred on the background of anticoagulant therapy in combination with pregravid cofactor vitamin therapy. During pregnancy, the patient received low molecular weight heparins in therapeutic doses in combination with acetylsalicylic acid at a dose of 150 mg per day, diosmin 600 mg and cofactor vitamin therapy. According to the results of combined screening in the I trimester, with the calculation of the risks of preeclampsia, the woman was classified as a high risk group for its development. At 23-24 and 32-33 weeks of gestation, an analysis was performed to calculate the risk of perinatal complications in the II-III trimesters by determining the ratio of water-soluble tyrosine kinase-1 / placental growth factor (Sflt-1/PlGF). The data obtained indicated that the preventive therapy prescribed to the patient was adequate and effective. The pregnancy was completed at the full 37 weeks of gestation by spontaneous delivery in cephalic presentation without complications. A boy was born weighing 2950 g, Apgar score - 7/8. Conclusions. The clinical case is a vivid example of how well-timed, adequate prophylactic therapy can work efficiently and effectively, even in women with a rather burdensome thrombotic and obstetric history. This case confirms the necessity and expediency of using the entire modern diagnostic arsenal that exists in Ukraine to predict the occurrence of «Great» obstetric syndromes, which to this day occupy one of the leading places in the structure of maternal and perinatal losses. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

Limit Bipolar Sequences for Patchwork-Based Robust Digital Audio Watermarking
Authors: Gofman Maksim , Kornienko Anatolij
Published: March 2023

Ensuring the robustness of digital audio watermarking under the influence of interference, various transformations and possible attacks is an urgent problem. One of the most used and fairly stable marking methods is the patchwork method. Its robustness is ensured by the use of expanding bipolar numerical sequences in the formation and embedding of a watermark in a digital audio and correlation detection in the detection and extraction of a watermark. An analysis of the patchwork method showed that the absolute values of the ratio of the maximum of the autocorrelation function (ACF) to its minimum for expanding bipolar sequences and extended marker sequences used in traditional digital watermarking approach 2 with high accuracy. This made it possible to formulate criteria for searching for special expanding bipolar sequences, which have improved correlation properties and greater robustness. The article developed a mathematical apparatus for searching and constructing limit-expanding bipolar sequences used in solving the problem of robust digital audio watermarking using the patchwork method. Limit bipolar sequences are defined as sequences whose autocorrelation functions have the maximum possible ratios of maximum to minimum in absolute value. Theorems and corollaries from them are formulated and proved: on the existence of an upper bound on the minimum values of autocorrelation functions of limit bipolar sequences and on the values of the first and second petals of the ACF. On this basis, a rigorous mathematical definition of limit bipolar sequences is given. A method for searching for the complete set of limit bipolar sequences based on rational search and a method for constructing limit bipolar sequences of arbitrary length using generating functions are developed. The results of the computer simulation of the assessment of the values of the absolute value of the ratio of the maximum to the minimum of the autocorrelation and cross-correlation functions of the studied bipolar sequences for blind reception are presented. It is shown that the proposed limit bipolar sequences are characterized by better correlation properties in comparison with the traditionally used bipolar sequences and are more robust.
STRATEGIE WYKONYWANIA LOTÓW JAKO POTENCJALNE ŹRÓDŁA ENERGII DLA BEZZAŁOGOWYCH STATKÓW POWIETRZNYCH

Bezzałogowe statki powietrzne w ostatnich dekadach coraz bardziej zyskują na popularności. W związku z wszechstronnością zastosowań, zaczynając od czysto hobbystycznego poprzez profesjonalną fotografię lub misje ratowniczo-poszukiwawcze, platformy bezzałogowe muszą sprostać rygorystycznym wymogom. Rozwój, miniaturyzacja i masowa produkcja komponentów elektronicznych pozwala na znaczącą zmienność w konfiguracji platformy oraz jej rozmiarze. Niemniej, wszystkie konstrukcje łączy wspólna cecha – ograniczona długotrwałość lotu. Rozwiązaniem powyższego ograniczenia może być użycie odnawialnych źródeł energii w formie promieniowania słonecznego lub prądów wznoszących. Techniki lotu stosowane przez ptaki i z powodzeniem powielone przez pilotów szybowców są najlepszym dowodem możliwości zwiększenia długotrwałości lotu. Energia słoneczna zmagazynowana w akumulatorach podczas dnia może zostać zużyta na zasilanie samolotu w godzinach nocnych. W ramach artykułu dokonano przeglądu platform zdolnych do ciągłego lotu. Bazując na wykonanej analizie, zaprezentowano zalety oraz ograniczenia takich konstrukcji. Wnioski uzyskane z tego etapu staną się kluczowym wymaganiem dla rozwoju unikatowej platformy badawczej. W pierwszej kolejności zbadano wpływ technik latania na długotrwałość lotu. Ze względu na fakt, że proponowane rozwiązania są czułe na warunki pogodowe i silnie zależą od geograficznej lokalizacji, celem autorów było zbadanie możliwych do uzyskania korzyści w wydłużaniu czasu lotu. W celu określenia bilansu energii wykonano serię symulacji w pakiecie MATLAB/Simulink. Przyszłe prace skoncentrują się na efektywnym połączeniu technik latania z użyciem prądów wznoszących.
