Prospective trends in the world economy under the influence of global challenges: projections for Ukraine
Authors: Ryvak Nataliya O.
Published: April 2024

The main trends in the development of the world economy in the context of global challenges caused by geopolitical crises and wars and serious changes in demography, world wealth, technology, and climate are analyzed. The systemic risks of trade tensions, the growth of the debt level, and the decrease in the monetary policy’s effectiveness in the world's leading economies are studied in the context of Ukraine. The negative trends of a consistently high level of core inflation, which will require a further increase in interest rates or a prolonged maintenance of their high indicators, are outlined. High inflation has led to an erosion of real incomes and a global cost-of-living crisis, pushing millions of people to the brink of poverty and economic hardship. The reasons for the deterioration of the economic situation in the United States, the EU, China, and other leading world economies affecting the economies of other countries are examined. Consumers have been cutting back on their spending due to rising interest rates, lower real incomes, and a significant decline in household net worth. The dependence between the deterioration of macroeconomic stability in the world and additional threats to economic security and international support of Ukraine is detected. Therefore, based on the study, the author substantiates the following priority initiatives: the expediency of independent formation by Ukraine of an environment that will be favorable for the development of domestic entrepreneurship in the open economic space and capable of withstanding competitive pressure in the domestic and foreign markets; accelerating the implementation of the European Commission’s package of recommendations and the successful completion of basic reforms; creating conditions for attracting and improving the security of investments in Ukraine in wartime; accelerating integration into the European economic area. It is important to increase investors’ confidence in Ukraine through the use of investment protection tools, in particular investment insurance, strengthening control over the fulfillment of contractual obligations under investment agreements, strengthening the legal framework, expanding cooperation with international organizations, providing access to a fair trial within independent arbitration courts, conducting structural reforms aimed at improving the business climate, easing bureaucracy, and increasing accessibility of information for investors.
Theoretical approaches to interpreting the essence of banking innovations and determining the goals of their implementation
Authors: Martynyuk Rostyslav F.
Published: April 2024

Any scientific study of the development of economic systems or society directly or indirectly determines the need for innovations, which are the driving force of qualitatively new, progressive changes. The article examines the evolution of the concept of "innovation" and the features of its application in banking. The author addresses theoretical approaches to the interpretation of the essence of "banking innovation" and reveals that the main goal of the innovative activity of banking institutions is to make a profit and improve their competitive positions. The article substantiates that the innovative activity of banks is not the same as the concept of financial innovations, and the latter is an element of the innovative activity of banking institutions. Characteristics of financial innovations and the reasons for the frequent identification of the essence of financial and banking innovations are analyzed. They are analyzed and structured according to the goals and directions of their implementation. The comparison of innovations and financial innovations is analyzed and their main similarities and differences are revealed. The dependence of financial investments on the bank’s competitiveness and the peculiarities of their relationship are outlined. Factors influencing the innovative component of banking institutions are structured. The article shows that the presence of qualitatively new changes contributing to increasing the efficiency of the use of banking institutions’ resources in the conditions of digitalization and remote banking is the main characteristic of banking innovations. It also reveals that the trend towards digitalization of all spheres of social life, including banking, has a significant influence on banking innovations, however, in the context of this trend, the aspect of guaranteeing the financial security of the banking segment becomes important. Given the resource investments aimed at financing the implementation of innovations in the field of banking services, the characteristic signs of investment are identified. The actual implementation of innovations, like investments, involves spending money now in order to obtain economic benefits in the future. That is, the objective and ultimate goals of innovation and investment coincide. However, the concept of investment is broader than innovation and includes the latter. They correlate as a whole and a unit when viewed from the perspective of philosophical categories.
Universal design in transport
Authors: Stasiak-Cieślak Beata , Grabarek Iwona
Published: April 2024

The article presented development directions in product, devices and service design related to ensuring broader accessibility for all users, with a particular focus on transportation. In this aspect, the requirements recorded in both national and international legal acts related to accessibility, including accessibility in transport, were reviewed. Compliance the analyzed regulations requires a human-centric approach to the design of means of transport, which in turn increases the likelihood of their wider use by people with various mobility needs.. However, this necessitates the designer's knowledge of the needs and limitations of end users. Special attention was paid to the concept of Universal Design (UD), based on the 7 principles formulated by Ronald Mace. Examples of technical solutions from the field of transportation innovation based on the principles of Universal Design were presented. The application of such an approach was also demonstrated in individual transportation – a vehicle accessible to drivers with limited lower limb mobility. In the summary, the authors emphasize that the devices available on the market are designed with wide customization possibilities in mind, without the need for extensive modifications. Therefore, most of these devices can be used by a wide range of people with disabilities, consistent with UD principles.

Driving a car independently significantly enhances the quality of life, particularly for individuals with mobility disabilities. Wheelchair users face several challenges when loading and unloading their wheelchairs into and from vehicles, hindering their personal transportation independently. The influence of wheelchair design on the wheelchair and car compatibility for self-loading and unloading hasn't been fully explored in the scientific literature; therefore, this study investigates the impact of various design features found in modern wheelchairs on their suitability for disabled drivers. Four types of wheelchairs were compared in this study; two participants with paraplegia, one male and one female, participated in the tests. Video recordings captured the procedures for getting in and out of the vehicle. Subsequent results analysis involved breaking down these procedures into steps and comparing them. The study demonstrated that times of independent entry into a car and loading of a wheelchair ranged from 48 to 74 seconds, while exiting the vehicle and loading a wheelchair phase took between 56 and 86 seconds. A key takeaway from this research is that dividing the wheelchair frame, the largest and heaviest component, into two parts facilitates loading and unloading processes. However, this may slightly increase the duration of these activities. Detaching the seat aids more individuals with limited upper body strength.
Application of machine learning methods to analyze customer migration risk in terms of corporate financial security
Authors: Stoica Ramona-Monica , Vilau Radu , Voicu Daniela , Grzelak Malgorzata
Published: April 2024

Effective prediction of customer migration is only possible through knowledge of the customer life cycle, which is characterized by the length of the relationship between buyer and provider, i.e. customer retention. A concept of opposite importance is customer migration, defined as the partial or total abandonment of the products or services offered by a company. Its knowledge and ability to predict it is crucial in terms of ensuring the continued financial security of target companies. The primary objective of this article was to present a method for assessing the risk of telecom industry customer migration using machine learning methods. The objective was achieved through the use of research methods, theoretical deductions such as and induction, system analysis and synthesis, and mathematical modelling, which additionally allowed for a practical analysis of the migration of customers of the telecommunications industry. Predictors with the greatest impact on the phenomenon under study were selected. It should be noted that the gain chart indicates that, in the case of contacting the 20% of customers selected by the models, the target coverage would be at the following levels, respectively: 70% for the boosted tree model and the decision tree based on the CART algorithm, and 75% for the random forest model. The research niche addressed in the article is the development of methods for assessing migration risk using machine learning techniques. The tool developed in the article can support decision-making in the creation of marketing campaigns aimed at retaining the largest number of customers.

Published: April 2024

Artificial Intelligence (AI) has proven valuable in almost every field of endeavour, including education, sciences, engineering, technology, medical sciences, and numerous other areas of application. Despite its widespread usefulness, concerns have arisen about AI potentially displacing jobs due to its highly advanced capabilities, commonly called the "god-man effect." One remarkable AI product is ChatGPT, a Chatbot developed by an open AI company in the USA that is capable of engaging in conversations that resemble human interactions. This study explores the strengths and limitations of ChatGPT for data analysis, with the primary objective of assessing whether ChatGPT poses a threat to the job of data analysts. An econometric dataset with a sample size of thirty (30), which consists of one dependent variable and three independent variables, was simulated. The dataset was intentionally generated with issues like multicollinearity, outliers, and heteroscedasticity. Subsequently, multiple tests were conducted on the datasets to confirm the presence of these problems. The ChatGPT 3.5 and 4.0 versions were then used to analyse the data to examine this chatbot's prowess in performing data analysis. ChatGPT 3.5 and 4.0 accurately predicted the suitable statistical tool for analyzing the simulated datasets. Both versions of ChatGPT emphasized that the expertise of a professional data analyst would be necessary. While they could offer guidance on data analysis, they cannot perform the analysis themselves as they are solely AI models. ChatGPT can help with what to do next when a data analyst gets stuck. However, they should not be recognized as an authority in making statistical decisions. Therefore, ChatGPT may not replace data analysts but could make their job easier by serving as a helpful resource to turn to when they encounter challenges.

Аспирационная биопсия яичка с целью получения сперматозоидов для преодоления мужского бесплодия при синдроме Циннера с помощью вспомогательных репродуктивных технологий: клинический случай
Authors: Корнеев И.А. , Самойлова К.О.
Published: April 2024

Актуальность: Синдром Циннера – редкая врождённая аномалия развития урогенитального тракта у мужчин, характеризующаяся наличием кисты семенного пузырька, ипсилатеральной аплазией почки и ипсилатеральной обструкцией семявыносящего протока, которая может привести к бесплодию. Представления о путях преодоления проблемы бесплодия в рамках этой патологии противоречивы, поскольку устранение обструкции не всегда приводит к восстановлению способности к зачатию естественным путем. Это определяет необходимость поиска альтернативных методов помощи таким пациентам и представления всех клинических случаев успешного преодоления бесплодия у мужчин с синдромом Циннера.Цель исследования – показать и проанализировать опыт преодоления бесплодия у пациента с синдромом Циннера при помощи чрескожной аспирационной биопсии яичка с последующим использованием сперматозоидов в программе вспомогательных репродуктивных технологий (ВРТ) с применением методики интрацитоплазматической инъекции сперматозоида (ИКСИ).Материалы и методы: В исследовании использован метод ретроспективного анализа результатов обследования и лечения пациента, обратившегося в центр репродуктивной медицины для преодоления бесплодия в браке после оперативного лечения по поводу кисты семенного пузырька.Результаты: В статье представлен клинический случай преодоления мужского бесплодия при синдроме Циннера с помощью ВРТ.Несмотря на проведенное пациенту лечение в виде резекции кисты семенных пузырьков, бесплодие сохранялось, в связи с чем была произведена биопсия яичка и оплодотворение яйцеклетки методом ИКСИ. После успешного культивирования произведен перенос эмбриона. У супруги пациента наступила клиническая беременность, завершившаяся рождением здорового ребёнка.Заключение: Данный клинический случай демонстрирует возможности применения ВРТ и простых малоинвазивных методов получения сперматозоидов для успешного преодоления бесплодия без радикального оперативного лечения у больных, не имеющих других снижающих качество жизни симптомов. Увеличение числа наблюдений мужчин с синдромом Циннера в последние годы является предпосылкой для информирования об этой проблеме и путях ее преодоления широкого круга специалистов по репродуктивной медицине.

Authors: Vanegas Pesántez Mayra Ivón , Betancourtt Aguilera Jimmy Omar , Recalde García Frans Andres
Published: April 2024

Currently, Ecuador and other Spanish-speaking countries are not achieving positive results with their students in the teaching-learning process of the English language due to the application of traditionalist methodologies or approaches, which lead to student disinterest. Another negative factor is the limited experience of some teachers in the English language area. The objective of this article is to understand the methodologies and didactic approaches used by teachers and identify which of these methodologies and approaches yield better results in teaching the foreign language. This research is qualitative, as various bibliographic sources were analyzed to collect and develop the information. It was identified that the best approach and technique to be used in teaching a foreign language is the communicative approach, as students learn to perform in everyday real-life activities, and to make it more dynamic and engaging for students, playful activities and character characterization through role play.

HS Psc b joins a small population of young, close-in giant planet candidates with robust age and mass constraints and demonstrates that giant planets can either migrate to their close-in orbital separations by 130 Myr or form in situ. Given its membership in a young moving group, HS Psc represents an excellent target for follow-up observations to characterize this young hot Jupiter further, refine its orbital properties, and search for additional planets in the system.
Detection of Contact Binary Candidates Observed By TESS Using the Autoencoder Neural Network
Authors: Ding Xu , Song ZhiMing , Wang ChuanJun , Ji KaiFan
Published: April 2024

A contact binary may be the progenitor of a red nova that eventually produces a merger event and have a cut-off period of around 0.2 days. Therefore, a large number of contact binaries is needed to search for the progenitor of red novae and to study the characteristics of short-period contact binaries. In this paper, we employ the Phoebe program to generate a large number of light curves based on the fundamental parameters of contact binaries. Using these light curves as samples, an autoencoder model is trained, which can reconstruct the light curves of contact binaries very well. When the error between the output light curve from the model and the input light curve is large, it may be due to other types of variable stars. The goodness of fit (R
2) between the output light curve from the model and the input light curve is calculated. Based on the thresholds for global goodness of fit (R
2), period, range magnitude, and local goodness of fit (R
2), a total of 1322 target candidates were obtained.
A Linear Model for Inertial Modes in a Differentially Rotating Sun
Authors: Bhattacharya Jishnu , Hanson Chris S. , Hanasoge Shravan M. , Sreenivasan Katepalli R.
Published: April 2024

Inertial wave modes in the Sun are of interest owing to their potential to reveal new insight into the solar interior. These predominantly retrograde-propagating modes in the solar subsurface appear to deviate from the thin-shell Rossby–Haurwitz model at high azimuthal orders. We present new measurements of sectoral inertial modes at m > 15 where the modes appear to become progressively less retrograde compared to the canonical Rossby–Haurwitz dispersion relation in a corotating frame. We use a spectral eigenvalue solver to compute the spectrum of solar inertial modes in the presence of differential rotation. Focussing specifically on equatorial Rossby modes, we find that the numerically obtained mode frequencies lie along distinct ridges, one of which lies strikingly close to the observed mode frequencies in the Sun. We also find that the n = 0 ridge is deflected strongly in the retrograde direction. This suggests that the solar measurements may not correspond to the fundamental n = 0 Rossby–Haurwitz solutions as was initially suspected, but to those for a higher n. The numerically obtained eigenfunctions also appear to sit deep within the convection zone—unlike those for the n = 0 modes—which differs substantially from solar measurements and complicates inference.
Formation of Limb-brightened Radio Jets by Angle-dependent Energy Extraction from Rapidly Rotating Black Holes
Authors: Hirotani Kouichi , Shang 尚 Hsien 賢 , Krasnopolsky Ruben , Nishikawa Kenichi
Published: April 2024

Using general relativistic magnetohydrodynamic simulations, it has been suggested that the rotational energy of a rapidly rotating black hole (BH) is preferentially extracted along the magnetic field lines threading the event horizon in the middle and lower latitudes. Applying this angle-dependent Poynting flux to the jet downstream, we demonstrate that the jets exhibit limb-brightened structures at various viewing angles, as observed from Mrk 501, M87, and Cyg A between 5° and 75°, and that the limb brightening is enhanced when the jet is collimated strongly. It is also found that the jet width perpendicular to the propagation direction shrinks at the projected distance of the altitude where the jet collimates from a conical shape (near the BH) to a parabolic one (in the jet). Comparing with Very Long Baseline Interferometry observations, we show that this collimation takes place within the deprojected altitude of 100 Schwarzschild radii from the BH in the case of the M87 jet.
Trapped Water on Silicates in the Laboratory and in Astrophysical Environments
Authors: Potapov Alexey , Jäger Cornelia , Mutschke Harald , Henning Thomas
Published: April 2024

The existence of strongly bound water molecules on silicate surfaces, above the desorption temperature of water ice, was first predicted by computational studies and has recently been demonstrated by laboratory experiments. Such trapped water may be present in various astrophysical environments and there is now evidence for its presence in the diffuse interstellar medium (ISM) and in extraterrestrial particles. We present here new results of a laboratory study of the phenomenon of trapping (strong bonding) of water molecules by silicates. We show that the efficiency of the trapping is strongly dependent on the properties and composition of the surface. Our results point out that the presence of trapped water should be due to the hydrophilic properties of the silicate surface and that the nature of the trapping is physical (physisorption rather than chemisorption). We demonstrate that water can be trapped on silicates up to temperatures of about 470 K, which speaks for the presence of wet silicate grains in the terrestrial planet formation zone in planet-forming disks. Studying the thermal and UV stability of trapped water, we conclude that the detection of trapped water in the diffuse ISM speaks for its efficient continuous formation. We discuss our results as relevant to fundamental scientific questions, such as the oxygen depletion problem, the origin of water on Earth, and the formation of rocky planets.
Insights into Neutron Star Equation of State by Machine Learning
Authors: Guo Ling-Jun , Xiong Jia-Ying , Ma Yao , Ma Yong-Liang
Published: April 2024

Due to its powerful capability and high efficiency in big data analysis, machine learning has been applied in various fields. We construct a neural network platform to constrain the behaviors of the equation of state of nuclear matter with respect to the properties of nuclear matter at saturation density and the properties of neutron stars. It is found that the neural network is able to give reasonable predictions of parameter space and provide new hints into the constraints of hadron interactions. As a specific example, we take the relativistic mean field approximation in a widely accepted Walecka-type model to illustrate the feasibility and efficiency of the platform. The results show that the neural network can indeed estimate the parameters of the model at a certain precision such that both the properties of nuclear matter around saturation density and global properties of neutron stars can be saturated. The optimization of the present modularly designed neural network and extension to other effective models is straightforward.

Published: April 2024

Seven rotational and fine-structure transitions of the deuterated molecular ion SD+ in the X
3Σ− ground electronic state have been measured in the 271–863 GHz region in the laboratory. This ion has been produced by direct-current glow discharge using a mixture of D2S and argon in a free space cell in a temperature range of −140°C to −160°C. The rotational, centrifugal distortion, spin–spin interaction, and hyperfine constants have been determined; the standard deviation of the residuals in the fitting is 109 kHz. The set of obtained spectroscopic parameters provides a list of accurate submillimeter rest frequencies of SD+ for astronomical detection. We have investigated lines of SD+ toward the quasar PKS 1830-211 using the Atacama Large Millimeter/submillimeter Array archive, as the z = 0.89 molecular absorber exists in front of this quasar. A data set covering the 297 GHz region includes the N

Published: April 2024

Based on high-resolution measurements from the Magnetospheric Multiscale mission from 2015 May to 2018 June, we statistically investigate the properties of small-scale field-aligned currents (SFACs) in the magnetopause boundary layer. A total of 2235 SFACs are successfully identified. The durations of SFACs mainly fall between 0.2 and 0.3 s. Over 90% of SFACs have a width of less than 1 ion inertia length and are primarily distributed from 5 to 25 electron inertia lengths, implying that the SFACs belong to the kinetic-scale current layer. The main carriers of SFACs are electrons, and over 70% of SFACs exhibit net energy dissipation (i.e.,

′ > 0) with the majority of energy dissipation taking place in the parallel direction. SFACs are widely distributed spatially, and the occurrence rate of SFACs is higher in the boundary layer closer to the magnetosphere. Additionally, less than half of the total SFACs are identified in well-known structures, including the magnetic reconnection region, flux transfer event, Kelvin–Helmholtz vortex, and exhaust region, and 54% of the SFACs are in the “others” unknown structures. These results improve our comprehension of the current system at the magnetopause and the roles of SFACs in the coupling between the solar wind and magnetosphere.

Published: April 2024

A bagrid catfish, Bagrichthys micranodus Roberts, 1989, has been reliably reported only from Borneo Island, whereas a pangasiid catfish, Pangasianodon hypophthalmus (Sauvage, 1878), originally from the Mekong and Chao Phraya rivers, has been widely introduced for aquaculture throughout southeast Asia. However, an ichthyofaunal survey of Cala Lake, South Sumatra, disclosed significant distribution extensions for both species, that of B. micranodus being the first from a land mass other than Borneo Island. Additionally, P. hypophthalmus was recorded from a natural freshwater habitat, outside the controlled environments of aquaculture facilities. The specimens are described in detail and comparisons are made with closely related species.

La non-équivalence de Joyce et Nora à Trieste
Authors: Dalzell Tom
Published: April 2024

Pour Jacques Lacan, malgré sa théorie du non-rapport sexuel entre masculinité et féminité, un tel rapport peut en fait être possible là où il n’y a pas d’équivalence entre elles. Cet article examinera ce que les années que James Joyce et Nora Barnacle ont passées à Trieste nous apprennent sur leur non-équivalence. Et il montrera que, malgré sa théorie du non-rapport, Lacan trouve que, par son écriture, Joyce a réussi à atteindre un rapport sexuel, ce que Lacan lui-même avait eu du mal à écrire.
La raison depuis Freud et le réel de la guerre
Authors: Laurent Éric
Published: April 2024

Le titre de l’article de mon contradicteur condense deux titres de Kant. Au long de son texte il reproche d’accorder trop de crédit aux vaticinations de Cioran, demande des preuves académiques, s’autorise de Hannah Arendt. Je lui réponds que Kant c’est très bien, à condition d’y ajouter Sade. Et que seul cet ajout permet de définir la raison après Freud. Il pense aussi que Lacan parle de « pouvoir capitaliste » au sens marxiste du terme. C’est une erreur. Il y a peu de marxisme dans l’emploi de Lacan de ce terme. Enfin, je prends une distance avec les idéaux pacifistes qu’il pose comme un impératif kantien. Aux projets de paix perpétuelle, je préfère les équilibres calculés et précaires, inspirés par sentiment du réel de la guerre et l’angoisse devant ses conséquences.

En abordant de façon systématique la dimension spatiale des pratiques protestataires sous différents aspects – conditions sociales d’émergence, revendications, répertoire d’actions –, cet article montre comment l’espace, dans ses composantes matérielle et symbolique, constitue un ressort de politisation important. Dans un premier temps, l’article examine les effets du contexte résidentiel sur la formation de collectifs socialement différenciés dans deux micro-espaces de la ville en prêtant attention aux trajectoires individuelles tout autant qu’aux interactions et pratiques dans l’espace de vie des mères (et pères) mobilisé·es. Or, si ces groupes ont des intérêts sociaux fortement contrastés, ils convergent pourtant autour d’un mot d’ordre militant, l’égalité territoriale. Dans un deuxième temps, l’article interroge ainsi les modalités d’appropriation de ce mot d’ordre en examinant les résonances discursives entre discours militants et catégories de l’action publique, et les formes de circulation et d’appropriation de ces catégories dans l’espace local. Enfin, la fédération et l’alliance de ces collectifs au niveau départemental, revendiquant « l’égalité 93 », conduisent à des tensions ou distances entre groupes sociaux localisés. Ainsi, si les catégorisations spatiales du monde social permettent la politisation et l’accès de groupes dominés à l’espace public et politique, elles contribuent aussi à construire la légitimité et l’autorité des groupes dominants dans l’espace local.

The field of artificial intelligence (AI) is very promising with the emergence of machine learning and deep learning algorithms. The rise of convolutional neural networks (CNN) is very propitious in deep learning as it is more accurate and powerful than previously known soft computational models like artificial neural networks (ANN) and recurrent neural networks (RNN). CNN is ANN with steroids. These soft computational models are inspired by biological models that give an approximate solution to image-driven pattern recognition problems. The near perfect precision of CNN models offers a better way to recognize patterns and solve real-world problems and provide approximate solutions which are near precision. These technologies have enhanced the trust with humans. Its results have been accepted widely. This chapter aims to provide brief information about CNNs by introducing and discussing recent papers published on this topic and the methods employed by them to recognize patterns. This chapter also aims to provide information regarding dos and don'ts while using different CNN models.
