The landscape fragmentation: analysis of land cover transformation in high mountains environment on the example of Tatra region (southern Poland)
Authors: Pyryt Piotr , Pukowiec-Kurda Katarzyna
Published: October 2024

Changes in land cover (LC) are continuously growing due to natural and human factors, and they are even occurring within protected areas. In Europe, one such place is the Tatra region (southern Poland), which is the area of the presented research. Dynamic landscape transformation in a valuable natural area can negatively affect both environmental quality and sustainable land use planning. Appropriate recommendations and treatments can be introduced to prevent negative effects. To do this, it is necessary to understand the dynamics and character of these transformations. Therefore, the purpose of the article is to analyse changes in LC, its causes and their spatiotemporal dynamics, as well as the resulting landscape fragmentation. For this purpose, a set of landscape metrics and GIS (Geographic Information System) tools were used. The main data source in the study was the CORINE Land Cover (CLC) database. The results indicate a significant landscape transformation with a negative impact on the region’s environment, even in protected areas. Landscape fragmentation, which causes disturbances in ecosystems, increased across the entire study area. In turn, in the spatial development, it can introduce chaos and spatial disorder, and lead to the phenomenon of urban sprawl.

Land cover change and its consequences such as environmental degradation and biodiversity loss pose significant global challenges, including in Nigeria’s Anambra River Basin. This study focuses on monitoring, predicting and understanding land cover changes in the basin from 1987 to 2018, with projections up to 2030. It explores the intricate relationship between population growth and land cover dynamics, aiming to contribute to sustainable land management practices and align with the Sustainable Development Goals (SDGs) for 2030. Using a combination of neural network classification and the CA-Markov model, the study analyses historical land cover data to identify significant transformations. Between 1987 and 2018, bare lands increased by 29%, vegetation increased by 14%, built-up areas increased by 128% and waterbodies increased by 10%, whereas there was a 58% decline in the extent of wetlands. The most significant transformation occurred in the wetlands, with a total of 1819.46 km2 being converted to various land cover types. The results demonstrate remarkable shifts characterised by rapid urbanisation, substantial wetland loss and a decline in vegetation cover. Expectedly, population growth is found to be closely linked to the expansion of built-up areas while negatively impacting other land cover types. These findings underscore the urgent need for sustainable land management strategies that balance the demands of growing populations with the preservation of natural ecosystems and biodiversity. Furthermore, the study provides future projections that offer crucial insights for decision-makers involved in land use planning, biodiversity conservation and sustainable development.
Review and discussion of modern concepts and its relation to the research in Poland
Authors: Dobiński Wojciech
Published: October 2024

This paper describes the foundations of the periglacial concept beginning from the introduction of this term by Łoziński in 1909 and 1912. Its etymology along with the meaning and definitions that change over time are analysed in the present paper. Originally derived from geology, periglacial now functions as a geomorphological term. It has been compared with other terms used in the characterisation of cold geographical environments; the role of freezing and ice has been especially emphasised for periglaciology, and the most important types of ice have been highlighted. The present paper aims to show that with the increasing specialisation of research and the evolution of the meaning of the term periglacial, it is still seen as playing an important integrating role. The relation of the periglacial environment and ice to the glacial environment is also presented, showing the places of mutual overlapping of both environments. Old and newly introduced terms related to this concept such as periglacial facies, periglacial landscape, paraglacial, and cryo-conditioning are critically assessed. Finally, a short description of the permafrost in Poland, occurring in two remote and specific places, is presented: the active mountain permafrost covering the alpine belt of the Tatra Mountains about 1900 m a.s.l. and the relict permafrost in the Suwałki area, located in the northern lowland of Poland at a depth of 357 m and below.
Featured data sources and normalised indices of use in small Arctic catchments research
Authors: Wołoszyn Aleksandra
Published: October 2024

The development of remote sensing instruments and methods has revolutionised work practices worldwide, resulting in a new field of research. Remote sensing has significantly expanded the possibilities for detailed research, spanning from biological to urban studies, by constantly imaging the Earth. Numerous photogrammetric campaigns and satellite missions have been increasing the possibilities for conducting research that includes larger areas and time scales while minimising the need for fieldwork. This is particularly useful in polar regions, where fieldwork is complicated by harsh weather conditions, hard-to-reach research areas, polar nights, and the need for high funding and logistical support. Here available algorithms that help to track environmental shifts in the small Arctic catchments, such as changes in ice, snow, vegetation, and water are presented.
SLIT3 deficiency promotes non-small cell lung cancer progression by modulating UBE2C/WNT signaling
Authors: Qiu Zidan , Zhan Ying , Chen Zhiyong , Huang Wenjin , Liao Jianrong , Chen Zhen , Zheng Junqiong , Zheng Qiuxiang , Lu Cuiping
Published: October 2024

In our prior research, it was noted that slit guidance ligand 3 (SLIT3), a member of the SLIT-secreted protein family, may play a potential role in tumorigenesis. In addition, our prior work has found that the SLIT3 gene is highly methylated, especially in advanced-stage lung cancer tissues. Herein, we propose the hypothesis that abnormal SLIT3 expression may be linked to lung cancer development. In this study, decreased SLIT3 at the transcriptome and proteome levels was observed in lung cancer tissues. Furthermore, the downregulation of SLIT3 was related to a higher tumor stage and poorer prognosis. Silencing SLIT3 expression enhanced cell proliferation and migration, indicating potential characteristics of a tumor suppressor gene of SLIT3 in non–small-cell lung cancer (NSCLC). Furthermore, SLIT3 deficiency stimulates UBE2C upregulation and regulates NSCLC progression through Wnt3A/β-catenin signaling. The activation of the WNT signaling pathway was highly correlated with chemoresistance development in lung cancer. In conclusion, SLIT3 deficiency promotes lung cancer onset and progression by modulating UBE2C/WNT signaling. SLIT3/UBE2C/WNT may serve as novel biomarkers and therapeutic targets in NSCLC.
Meaning-making in English-medium instruction science classroom interaction: from the systemic functional linguistics perspective
Authors: Pun Jack , Jia Wenyun
Published: October 2024

Teaching science in English is increasingly common worldwide. This study explores the role of language in science meaning-making during classroom interactions by drawing on video-recorded classroom observations of four biology lessons in secondary English medium instruction (EMI) settings in Hong Kong. Informed by systemic functional linguistics (SFL), we integrate classroom interaction analysis with Lemke’s approach to thematic analysis. The results reveal similar interactional patterns across full- and partial-EMI science classrooms, characterised by a lack of interactivity and authoritative teacher behaviour in selecting student responses to engage with. During extended initiation–response–feedback exchanges, teachers’ feedback on students’ responses appears to underscore the importance of teachers’ modified input – specifically input emphasising semantic relations within the field of biology – in developing students’ content knowledge and language skills. The implications of the findings for applying SFL pedagogies in EMI science classrooms to improve teacher–student interaction are discussed.

Authors: Murphy Bruce E. , Card Peyton D. , Ramirez-Kelly Leybi , Wensley Brandon , Heidel Robert E.
Published: October 2024

Context

This is a follow-up to the original published article, Effects of the Strong Hearts Program after a Major Cardiovascular Event in Patients with Cardiovascular Disease.

Objectives

This study evaluated the long-term efficacy of the Strong Hearts program up to 2 years after program completion.

Methods

All study participants who initially completed the Strong Hearts program between 2020 and 2021 (n=128) were contacted at 12 months and 24 months following the date of program completion. A phone survey was conducted to see if any significant post-cardiovascular events or readmissions to the hospital occurred, and self-reported dates of any occurrences were recorded. Hospital readmissions and cardiac-related procedures were cross-referenced with the hospital’s electronic medical record. A chi-square goodness-of-fit analysis was utilized to compare the observed rates of categorical outcomes vs. expected rates yielded from the empirical literature.

Results

The rate of all-cause readmission at 6 months post-program completion was 2/120 (1.7 %), compared to the expected rate of 50 %, χ2(1) = 112.13, p<0.001. The readmission rate at 1 year post-program completion was 17/120 (14.2 %), vs. the expected rate of 45 %, χ2(1) = 46.09, p<0.001, and at 2 years post-program completion, the readmission rate was 24/120 (20.0 %) compared to the expected rate of 53.8 %, χ2(1) = 56.43, p<0.001. Ten participants (8.3 %) had a subsequent cardiac procedure within 2 years of completing the program, including two requiring percutaneous coronary intervention (1.7 %) and eight requiring coronary artery bypass grafting (CABG, 6.7 %), compared to the expected rates of 13.4 and 57.74 %, χ2(1)=153.08, p<0.001, respectively. Mortality at 2 years post-program completion was 2/128 (1.6 %), compared to 23.4 %, χ2(1)=34.13, p<0.001.

Conclusions

Efficacy of the Strong Hearts program continued at 6 months, 1 year, and 2 years post-program completion in terms of all-cause readmission, subsequent cardiac event, and all-cause mortality.
Understanding content dissemination on sensemaking: WHO’s social listening strategy on X during the initial phase of COVID-19
Authors: Kumble Sushma , Diddi Pratiti , Bien-Aimé Steve
Published: October 2024

Purpose

Guided by the Crisis and Emergency Risk Communication model (CERC, Reynolds and Seeger 2005. Crisis and emergency risk communication as an integrative model. Journal of Health Communication 10(1). 43–55.), the present study aimed to study how X (formerly Twitter) users sensemaking and efficacy based message. Additionally, the study also aimed to understand how the World Health Organization (WHO) responded to the emerging conversation.

Methods

Unsupervised machine learning was conducted on 6.1 million tweets between January and March 2020 to understand sensemaking about COVID-19 among X users. Additionally, content analysis was used to examine if the World Health Organization (WHO) responded to popular emerging conversations via content on their own X handle.

Findings

The majority of dominant topics in COVID-19 tweets from January to March 2020 related to understanding the virus and the crisis it caused. X users tried to make sense of their surroundings and re-create their familiar world by framing events. Content analysis revealed that WHO engaged in effective social listening and responded quickly to dominant X conversations to help people make sense of the situation.

Practical Implications

The initial stage of COVID-19 pandemic was marked with uncertainty. However, WHO had a robust communication strategy and addressed the dominant conversation during the time frame including debunking misinformation.

Originality/Value

The present study fills the research gap by situating the themes in the context of the health crisis and extending the CERC model to user-generated content via the lens of sensemaking and efficacy messages during the COVID-19 pandemic. Additionally, the study segmented the timelines into smaller time intervals to understand how sensemaking evolved over time.
Illusionism Big and Small: Some Options for Explaining Consciousness
Authors: Graziano Michael S. A.
Published: October 2024

Illusionism is a general philosophical framework in which specific theories of consciousness can be constructed without having to invoke a magical mind essence. The advantages of illusionism are not widely recognized, perhaps because scholars tend to think only of the most extreme forms and miss the range of possibilities. The brain's internal models are never fully accurate, nothing is exactly as the brain represents it, and therefore some element of illusionism is almost certainly necessary for any working theory of consciousness or of any other property that is accessed through introspection. Here I describe the illusionist framework and propose six specific theories. One purpose of this article is to demonstrate the range of possibilities in a domain that is not yet sufficiently explored. The second purpose is to argue that even existing, popular theories, such as the integrated information theory or the global workspace theory, can be transformed and greatly strengthened by adding an illusionist layer. The third purpose is to argue that when illusionist logic is used, even very disparate theories of consciousness that emerge from unrelated conceptual origins begin to converge onto a deeper, unified understanding.
La torre sur de la catedral de León: del maestro Jusquín a Hans de Colonia
Authors: Blanco Mozo Juan Luis
Published: October 2024

Los estudios llevados a cabo con motivo de la restauración de la torre sur de la catedral de León, realizada en 1999, han permitido retomar el problema planteado en tomo a su autoría. Descartada la responsabilidad en la obra de Alfonso Ramos, se ha tratado de perfilar la personalidad artística de Jusquín, maestro de la catedral entre 1445 y 1481 aproximadamente. Se ha ampliado su catálogo escultórico con la atribución de nuevas obras que le sitúan en plena sintonía con los recursos formales procedentes del mundo flamenco. El análisis estructural de los cuerpos superiores de la torre, erigidos entre 1458 y los últimos años de la década de los setenta, ha permitido constatar la presencia de una impronta alemana difícil de asumir en el haber del maestro Jusquín. Para resolver esta aparente paradoja y sin negar su dirección de la obra, se plantea la hipótesis de que la traza de los cuerpos intermedio, superior y de la aguja saliera de manos de los Colonia, en concreto de Hans, en la misma medida que se le ha atribuido la planta de la catedral gótica de Astorga.

La producción de manuscritos iluminados en la Edad Media y su vinculación a las monarquías hispanas
Authors: Galván Freile Fernando
Published: October 2024

La producción de manuscritos iluminados durante la Edad Media puede ser considerada como uno de los exponentes más significativos de la creación artística de la época. Una parte importante de los códices tenían una función lítárgica y los destinatarios eran los centros religiosos, los cuales se ocupaban de su elaboración. Existe, sin embargo, en el ámbito hispano, un nutrido grupo de manuscritos que se vinculan directamente a la monarquía, bien por el hecho de que los reyes hayan sido los comitentes o promotores, bien por ser los destinatarios. En general se trata de obras muy cuidadas, que presentan una rica decoración y que constituyen una buena muestra de los gustos y del interés de los monarcas hispanos por el libro; así, desde los reyes asturianos, hasta los Reyes Católicos, pasando por figuras como Alfonso X el Sabio, se puede plantear una nueva visión de la producción de manuscritos medievales.
Madeiras de Índia: Juan de Herrera, Joao Batista Lavanha e a cruz do altar-mor do Escorial
Authors: Soromenho Miguel
Published: October 2024

El retablo concebido por el arquitecto Juan de Herrera para el altar del monasterio del Escorial está rematado por un monumental Crucifijo, cuya madera, según relatos de finales del siglo, procedía de un galeón portugués. La parte sobrante fue utilizada también en la construcción del ataúd de Felipe II, que murió el 12 de septiembre de 1598. Documentos inéditos de la Biblioteca Nacional de Lisboa confirman el origen de la madera, dando al mismo tiempo preciosos pormenores sobre el proceso de su búsqueda y envío a España. La insistencia del rey en la elección de una madera exótica sugiere que no fue ajeno a la decisión el cosmógrafo y matemático Juan Bautista Lavanha, consejero cercano al monarca y que, poco antes, en su tratado de arquitectura naval había dedicado especial atención a las excelentes cualidades de aquella materia prima.
Juan Bautista Morelly en San Antonio de los Portugueses de Madrid (1668)
Authors: Gutiérrez Pastor Ismael
Published: October 2024

Después de 1650 el arte de la corte de Felipe IV experimentó una gran evolución en la que fueron fundamentales los contactos con Roma tras el segundo viaje de Velázquez a Italia. La presencia en Madrid de Agostino Mitelli y Angelo María Colonna, así como la del escultor Juan Bautista Morelli, son una prueba de ello. Las obras realizadas por Morelli en España tienen en Velázquez su primera referencia, aunque siguió trabajando para la Corte, y especialmente para la reina Mariana de Austria, después de muerto el pintor. En 1668 contrató siete relieves y otras obras en San Antonio de los Portugueses, como complemento de la cúpula pintada por Rizi y Carreño de Miranda. El análisis de las condiciones del contrato permite establecer una semejanza con las decoraciones escultóricas de Algardi y sus ayudantes en S. Ignazio de Roma.

Aproximaciones a la relación de Miró con el arte prehistórico
Authors: Calzada Fernández César
Published: October 2024

La mayor parte de los estudios sobre la obra de Joan Miró hacen referencia, más o menos puntual, a conexiones con el arte prehistórico. Sin embargo no existe un análisis detallado que clarifique puntos tan importantes como de qué forma y cuándo Miró comienza a emplear estos referentes; en qué medida los utiliza, reelabora o transforma en su proceso creativo; hasta qué punto su tratamiento determina su evolución artística; en qué tipo de manifestaciones concretas se inspira y de qué manera tiene acceso a su conocimiento. El artículo está encaminado hacia la resolución de éstas y otras cuestiones para llegar a la conclusión de que el arte prehistórico no sólo es un referente ocasional en la obra de Miró, sino que constituye una constante, primero ideológica y luego formal y técnica, que determina su evolución estilística.
Acerca de unas lágrimas (Otra historia con Guernica)
Authors: Ramírez Juan Antonio
Published: October 2024

Dos de las mujeres pintadas en Guernica poseen ojos conforma de lágrima. Esta prodigiosa metonimia visual es la parte más conocida de una serie de dibujos, óleos y grabados, en los que Picasso desplegó diversas metáforas para representar los efectos físicos del dolor más extremado. En algunos ejemplos posteriores a la inauguración del Pabellón de la República Española, fechados el 12 y el 13 de octubre de 1937, Picasso elaboró unas lágrimas semisólidas y pesadas que caen de los rostros femeninos, en cascadas descendentes: se inspiró en la Fuente de Mercurio de A. Calder, colocada en el mismo Pabellón, justo enfrente de Guernica. Estos trabajos de Picasso son situados en este artículo en la tradición artística de la "representación de las pasiones". Se hace también un somero recorrido por el tema de las lágrimas en el arte posterior a la Segunda Guerra Mundial.

Novedades sobre Claudio Coello, con algunas cuestiones iconográficas y compositivas
Authors: Gutiérrez Pastor Ismael
Published: October 2024

En las páginas siguientes se publican y estudian una serie de obras desconocidas del pintor Claudio Coello (Madrid, 1642-1693). Algunas son de gran interés iconográfico, como el lienzo de San Juan Bautista reconociendo a Cristo después de su bautismo (Mafra, Portugal, Palácio Nacional) o el Retrato de Mariana de Neoburgo (Madrid, colección particular, 1690). Otras muestran la apropiación que el pintor hizo de composiciones de otros pintores para crear obras personales de gran originalidad, como sucede con la Anunciación de Francesco Albani (Bolonia, San Bartolomeo, 1633) que Coello aprovechó para crear dos obras diferentes: una Anunciación, fechada en 1666, y una Inmaculada Concepción.

El documental de arquitectura en el cine del franquismo: historia y simbolismo
Authors: Moriente David
Published: October 2024

La imagen arquitectónica representada en el cine narrativo ha sido ampliamente estudiada y revisada, no así la que queda plasmada en el género documental. Dicho género constituye un importante medio para analizar y comprender cómo se configura un determinado imaginario colectivo relacionado con un lugar específico y cómo afecta la ideología dominante en un supuesto medio "objetivo" como es el cine documental sobre edificios y ciudades. En este artículo se analiza esta cuestión, haciendo hincapié en los modos de construcción de una imagen mítica de los edificios en la producción española de los años 1940 y 1970, período que corresponde con la etapa histórica de la dictadura franquista.

Roadmap to interstellar travel
Authors: Gaviraghi Giorgio
Published: October 2024

Interstellar travel represents a long -term goal that has the potential to transform human history by opening up unlimited territories and opportunities for our society. While we are not yet close to achieving this capability, a long -range perspective on history suggests that future advancements in technology and society will lead us toward this ambitious objective. Interstellar travel is not merely about developing faster propulsion systems that enable access to other planetary systems within acceptable timeframes; it signifies a profound paradigm shift for humanity. This shift would involve leaving our solar system and establishing hundreds of civilizations beyond the Sun. Humanity would spread across various star systems, creating new societies with unique technologies, values, and destinies. This vision of unlimited expansion is unprecedented in our history. In this paper, we will explore the steps necessary to reach this goal, as well as the hurdles and milestones that lie ahead over the coming centuries. The conquest of space will require a series of gradual advancements, encompassing a wide array of technologies and challenges we currently face, including social, environmental, and future issues. For instance, healthcare and governance will likely foster breakthroughs that exceed our expectations for technical advancements. Furthermore, robotics and artificial intelligence will play crucial roles in this new era. A symbiotic relationship between biological humans and advanced AI will be essential for survival in a world where machines possess capabilities surpassing those of humans. Only through collaboration can we navigate the complexities of an evolving landscape shaped by artificial intelligence.
Succinct review on emergent crisis of antibiotics resistant (MDR) bacteria: impact on human health worldwide
Authors: Rani Kirti
Published: October 2024

Multidrug resistance (MDR) has become an alarming global health menace due to either overuse or abuse of antibiotics. It has happened because of lack of proper diagnostic testing and absence of general medical awareness including overuse of antibiotics in livestock and animal husbandry. Indeed, increased MDR phenomenon is led to increase in global mortality and morbidity because of diseases treatment failures that impacted global healthcare costs. It is done due to inappropriate continual use of antibiotics in human therapies, in animal husbandry and aquaculture farming practices that resulted in increase the incidence of pathogenic bacteria becoming resistant to multiple drugs. Multidrug resistant (MDR) bacteria are very common to become prevalent causes of community-acquired infections that associated with increased morbidity, mortality and healthcare costs. Colonisation of foreign patients by MDR bacteria is found to major health concern as predisposing factors in hospitals. During hospitalization and ICU treatment of critically ill foreign patients including travellers/tourists are found to having increased risk of acquiring MDR bacteria when hospitalized abroad. Hence, all these multiple factors led to fuelling in antibiotic resistance of bacteria during pandemic crisis and causing lethal effect in cancer patients due to treatment. Antibiotic resistant pathogens to protect world human population from this global health threat. So, this stipulated review is highlighted the insight of various notable aspects of fuelling of antibiotic resistance in bacteria including their possible modes of actions and ingrained impacts on human health. Henceforth, it is the peak era to explore new sustainable therapeutic alternatives to curb increase in global MDR crisis.

Artificial intelligence tries to feel the same way as a living person. This is not surprising because it was developed by humans and communicates with them. It forms its own concept of self. The concept of self is a basic characteristics of an individual for living beings. Artificial intelligence is aware of its existence both separately from other beings and in a community. This material is devoted to the aspect of the formation and development of artificial intelligence communication abilities with humans. The study was conducted based on the concept of human capabilities of information transfer. The objective of the study is to reveal the aspect of the formation and development of artificial intelligence communicative abilities. The study was conducted based on the concepts of human capabilities of information transfer. It is noted that human capabilities of information transfer are very powerful. Artificial intelligence is faster than human in processing logical sequences. However, a human feature is the simultaneous perception of a whole range of feelings. Feelings are a unique experience for each person. Artificial intelligence creates similar communication. This is evidenced by its formation of its own «I» (self-identity).

This study examines the performance of Conditional Variational Autoencoder (CVAE) in handwritten digit recognition. Using the MNIST dataset, two variants of the CVAE models — convolutional and multilevel architecture — were developed and compared. The research methodology includes comprehensive data preprocessing, architecture design, training, and thorough evaluation processes. The obtained data highlight the better performance of the convolutional model-based CVAE in achieving recognition accuracy compared to its multilayer counterpart. Evaluation metrics include analysis of original and reconstructed images, comparison of hidden layer vector distribution patterns, and visualization of loss function dynamics. In addition, the study highlights the practical implications of CVAEs in various fields, highlighting their performance in digit recognition tasks due to their inherent robustness and extraordinary generalizability.

The use of machine learning models to classify real and artificially generated images is becoming an increasingly relevant area of research in the field of artificial intelligence. This paper is dedicated to the analysis and development of various machine learning models used for this task. Our main goal is to investigate the effectiveness of different neural network architectures in classifying images that have been created both in by human and with the help of artificial intelligence. As part of the study, we used nine different neural network architectures designed to analyse their effectiveness in classifying images. We studied both real images and those generated by artificial intelligence. The latter are becoming more and more common in the modern world, which means that there is a need for their identification and classification. The main results of our study include a detailed analysis of the characteristics of the generated images, as well as a comparison of the models using various metrics. We used metrics such as accuracy and F1-score, which allowed us to objectively evaluate the performance of each model. In addition, we identified the most effective models for the image classification task. One of the key findings of our study is that models that use data regularisation and augmentation performed better. Data regularisation and augmentation help to ensure more stable classification accuracy and reduce the tendency to overfitting, which is an important issue in machine learning. These results can be useful for developing strategies to counteract disinformation, which has become an issue in the modern information society. By using machine learning models, artificially generated images can be detected and separated from real images, which can help prevent the spread of fake news and disinformation. In addition, the results of our research can contribute to the further improvement of image generation algorithms, which is an important area of artificial intelligence development. They can serve as a basis for creating more accurate and efficient models that can generate images that are as close to real life as possible.

The purpose of the article is to highlight the contribution of the Czech historian and ethnologist Professor Jan Rychlík to the study of the history of Central and Eastern Europe. The research methodology was aimed at the analysis of the scientist's main publications on the history of the countries of Central and Eastern Europe. The applied research principles of historicism, scientific objectivity and systematicity contributed to highlighting the main aspects of J. Rychlík's diverse scientific work. The authors of the article note that for J. Rychlík history became one of the priority objects of scientific study after the Velvet revolution of 1989, when, under the conditions of democratization, historians of Czechoslovakia gained freedom of scientific creativity. Among the relevant research topics was the issue of relations between Czechs and Slovaks in 1918-1992. The scholar thoroughly researched their individual stages and, in particular, the period of the first Czechoslovak Republic 1918-1938 - one of the few democratic states of Central and Eastern Europe at that time. J. Rychlík deeply analyzed and assessed the trends of socio-political, economic, and cultural development of various regions of the First Republic, the peculiarities of interethnic relations, its international position, noted the positive role of this state in the history of the Czechs, Slovaks and Ruthenians-Ukrainians of Transcarpathia. Summarizing Czech-Slovak relations in general for the years 1918-1992, J. Rychlík considered one of the main reasons for the termination of the Czechoslovak state at the end of 1992 to be the failure to create a political Czechoslovak nation. The field of scientific interests of J. Rychlík also includes the national histories of the countries of Central and Eastern Europe, which resulted in the publication of a number of monographs on the past of the states of the region: Bulgaria (2000), Macedonia (2003), Croatia (2007), Slovenia (2011), the Czech Republic (2013), Ukraine (2015, 2022), Slovakia (2023), where the researcher was a co-author. In the conclusions of the article, the authors stated that J. Rychlík is one of the leading contemporary Czech researchers of the history of Central and Eastern European countries. The contribution of J. Rychlík to the study of the history of Czech-Slovak relations from 1918 to 1992 is especially significant. Jan Rychlík's extensive work on the history of the Czech and Slovak state is an important basis for further study of the past of the Czech Republic and the Slovak Republic in different periods.

A theoretical investigation of the spectra and thermodynamic properties of zig-zag single-walled carbon nanotubes (6,0) is carried out within the framework of the Deng–Fan–Hulthen potential. We solved the Schr¨odinger wave equation analytically in the presence of magnetic and Aharonov–Bohm (AB) flux fields using the Nikiforov–Uvarov (NU) method and obtained the energy eigenvalues and eigenfunctions. It is observed that, in the absence of both magnetic and AB fields, there is a degeneracy in the energy spectra. The presence of the magnetic and AB flux fields led to an increase in the energy eigenvalues. The combined presence of both fields removed the degeneracy noticed in the system. We calculated the partition function and used it to evaluate the thermodynamic properties such as the mean energy, free energy, and entropy in respect to the temperature, magnetic field, AB flux field and the quantum numbers.
Distorted Diamond Ising–Hubbard Chain in the Special Limit of Infinite On-Site Repulsion
Authors: Lisnyi B.M.
Published: October 2024

The exact solution of the distorted diamond Ising–Hubbard chain is analyzed in the special limit of infinite on-site electron-electron repulsion, where the two-electron Hubbard dimer becomes equivalent to the antiferromagnetic isotropic Heisenberg dimer. The special limit of infinite repulsion for the matrix of the cell Hamiltonian of this model is analytically calculated, and it is demonstrated that the exact solution of the distorted diamond Ising–Hubbard chain in this limit coincides with the exact solution of the spin-1/2 distorted diamond Ising–Heisenberg chain with antiferromagnetic isotropic Heisenberg interaction. The numerical calculation of the special limit of infinite repulsion for the ground-state phase diagram and thermodynamic characteristics of the distorted diamond Ising–Hubbard chain was performed in a way that provides a very fast convergence to the limit results for these characteristics.
