The preparation of large crystals is highly important for the characterization and application of a newly found structure but remains a challenge for one-dimensional (1D) C60 polymers. In this work, we successfully fabricated a 1D C60 polymer crystal via on-site annealing of a millimeter-sized C60 molecular crystal with α-Li3N at 500 °C and ambient pressure. Characterizations show that the C60 cages in the crystal have been efficiently connected, forming 1D chains along the <110> direction in an orthorhombic 3D structure. At the same time, the crystal maintains a morphology similar to that of the pristine C60 crystal, providing opportunities for characterization of all the facets of the crystal via Raman spectroscopy and thus suggesting the formation mechanism of such crystals.
Regional and Socioeconomic Dimensions of Tobacco Consumption in India: What Do NFHS-5 and GATS-2 Data Reveal?
Authors: Sarkar Raju
Published: January 2025

Background & objectives: Tobacco consumption remains a major public health issue in India, which is the second-largest consumer and third-largest producer of tobacco. Despite efforts like COTPA and the WHO FCTC, high tobacco use persists, especially in certain demographic groups. This study examines tobacco use trends and socioeconomic factors using data from the National Family Health Survey (NFHS-5) and the Global Adult Tobacco Survey (GATS-2).
Methods: The study analyzed data from GATS-2 (2016-2017) and NFHS-5 (2019-2021), which covered extensive household samples across India. Study used multivariable binary logistic regression to assess the impact of factors like residence type, age, gender, and health awareness on smoking behaviour in India.
Results: The NFHS-5 data revealed that 9% of women and 38% of men aged 15 and older use tobacco, with higher rates in rural areas (10.5% for women and 42.7% for men). Logistic regression showed that rural residents were 1.6 times more likely to smoke than urban residents. Age and gender significantly impact smoking patterns—females 13.0 times more likely to smoke compared to males, and the awareness of health risks related to smoking also influences smoking behaviour.
Conclusion: The study analyzes tobacco consumption trends in India using NFHS-5 and GATS-2 data that show persistent challenges despite regulations. Socioeconomic status significantly influences tobacco use. Recent data indicates decline in both smoked and smokeless tobacco. The study offers insights for policymakers to develop targeted tobacco control strategies for diverse population groups by considering prevalence and regional variations.

Bezpečnostné implikácie globalizácie vo vybraných sférach modernej ľudskej spoločnosti
Authors: Ivančík Radoslav
Published: January 2025

Globalization, as a highly dynamic and complex process, fundamentally affects various spheres of modern human society, including politics, economy, culture, energy, technology and, of course, security. Globalization increases the interconnectedness and dependence between states and regions, which increasingly connects national security with international security. Economic, political, technological and other changes, under the influence of deepening globalization, not only bring new opportunities, but also create many new vulnerabilities that can destabilize not only individual states, but also the entire human society. For this reason, the author deals with the security implications of globalization in the article, pointing to the transformation of traditional threats and the emergence of new, predominantly asymmetric and hybrid security threats. In this context, he emphasizes the need to deepen closer international cooperation in solving the global problems of humanity. In the presented study, the author applies an interdisciplinary scientific approach and uses scientific methods relevant to the researched topic in order to contribute to the academic discourse on the security aspects of globalization.

Diaphonization, also known as clearing and staining, is an invaluable technique for visualizing and studying the skeletal structures of animals. This study explores the application of diaphonization to examine bone development and soft tissues and determine causes of death in various animal species. By rendering tissues transparent and selectively staining bones and cartilage, diaphonization allows for detailed observation of skeletal morphology without dissection, thus preserving the integrity of specimens. This method enhances the understanding of morphological and anatomical structures and aids in determining the phylogenetic relationships between species. Diaphonization directly contributes to achieving Sustainable Development Goal (SDG) 4 by improving educational tools, indirectly supports SDG 10 by reducing educational inequalities, and SDG 14 and 15 by providing knowledge about the habitat of different species. Additionally, it plays a significant role in research, conservation, forensic science, and embryological studies.

Aspect-based Sentiment Analysis using Hierarchical Attention Networks
Authors: Pushkar Kumar
Published: January 2025

The proliferation of user contributed content in e-commerce, social media, and review sites have increased the demand for more accurate approaches to polarity detection. This need is met by Aspect-Based Sentiment Analysis (ABSA) that provides sentiments related to certain aspects of an entity which is useful for e-commerce, healthcare, and social media analysis. In this work, we propose the use of Hierarchical Attention Networks (HAN) for ABSA due to their ability to model at multiple granularities to enhance aspect-level sentiment classification. The presented framework improves position-sensitive embeddings and uses multi-head attentions to boost the scalability, interpretability, and performance of the cased model on multilingual and domain-shifted datasets. On various datasets, the proposed method showed better accuracy (93%), precision (92%), and F1-score (92%) than conventional methods. The model also performs well in dealing with implicit features and subtle sentiment patterns, which is further accompanied by attention visualization for better understanding. This research establishes new standards in ABSA, solving scalability and domain adaptability issues and opening the way to its application in large-scale sentiment analysis.

Aims: To assess the knowledge, attitude, and practice of blood donation among students studying medicine and health sciences, at Wolkite University, in 2024.

Methods: A cross-sectional study was conducted with 407 participant’s selected using simple random sampling from each department. Data were collected through semi-structured questionnaires and self-administration. The collected data were entered into Epi-data 3.1 and analyzed using SPSS-25.A scoring system was used, with one point given for each correct response and zero for incorrect responses. Participants could score a maximum of 16 points. Knowledge levels were categorized as poor (less than 8 points or more). Data distribution was assessed for normality using histograms and the Kolmogorov–Smirnov test. Categorical data were presented as frequencies and percentages, while continuous variables were analyzed using means and standard deviations. A p-value of less than 0.05 was considered as significant.

Results: Of the 407 participants, 257 (63.1%) were males and 150 (36.9%) were females with a mean age of 22.47±1.77. 94.6% of respondents scored 8 or more correct answers, indicating good knowledge. 32.8% heard about blood donation through mass media, and (49.1%) identified voluntary donors and family as blood sources. 95.3% had a good habit of donating blood, and 85.3% recommended voluntary donation for safe blood supply. 28.7% had donated blood, with 54.8% donating once.

Conclusion: Opportunities, information, social responsibility, and motivation are key factors influencing students’ blood donation behavior. Increased information, education, and communication (IEC) activities and seminars can raise awareness among medical students, encouraging voluntary donation, and inspiring others. Involving influential figures like celebrities, religious leaders, regular donors, and blood recipients can further motivate students to participate in blood donation campaigns.

Mimesis, analogía y semejanzas como vías de acceso a lo divino en la obra de Aristóteles.
Authors: Covarrubias Correa Andrés
Published: January 2025

En la filosofía de Aristóteles, enérgeia aparece como fundamento de mimesis, analogía y semejanza. Desde este ángulo es posible apreciar una suerte de corriente continua que permite superar la escisión radical entre ciencias prácticas, factivas y teóricas. Superada la escisión cabe visualizar el vínculo de unión entre la existencia humana y la divina. Esto no puede darse mediante una "nivelación desde abajo", como ocurre con la antropomorfización. En cambio, esa aspiración que cada ser manifiesta por aproximarse, en la medida de lo posible, a lo que 'es', en su perfección última y acabada, tiene la vida propia de la divinidad por expresión arquetípica. Aristóteles intenta un nuevo rumbo para explicar la relación entre el hombre y Dios. El ser es aquello que la mente ama, y el ser es para todos objeto de amor. En la substancia primera, ser y mente (Noús) se identifican, haciendo de Dios un ser nobilísimo y continuamente amado por el universo. El amor humano, el gozo de pensar que pensamos y que estamos vivos, nos permite contemplar al Primer Principio. Su separación, por tanto, no es una mera abstracción, sino la distancia reverente que impone la belleza, perfección y bondad, de la única substancia que es pensamiento de pensamiento y vida. Los entes, por su parte, participan (koinonei) (cf. Met. 1075 a, 24-25) todos para el todo. Se trata, pues, de una afirmación que nos remite indirectamente a Platón y la idea de methexis. El hombre, al poseer un lugar privilegiado en la naturaleza, está llamado a contemplar incluso aquellas cosas que parecieran estar sobre su capacidad (hyperanthropon) y, para lograrlo, debe esforzarse por hacerse semejante (homóioma) a lo divino, en lo que respecta a su actividad. Sólo en el desarrollo permanente de la virtud, considerada como enérgeia, puede llegar a ser el más amado por los dioses ( cf. E .N. 11 79 a,25-30).

Using Short Stories for Effective Grammar Instruction: An Experimental Study
Authors: Venkanna Dr. P. , . Pavani Dr. G
Published: January 2025

This study investigates the effectiveness of using short stories as a tool for teaching grammar in a more engaging and contextually meaningful manner. It aims to address the challenges of traditional grammar instruction, often criticized for being disconnected from real-world language use and monotonous for learners. Focusing on Shirley Jackson’s short story “The Lottery,” the research develops targeted activities that explore grammatical structures such as verb tenses, sentence complexity, and direct and indirect speech. These activities are designed to help learners see grammar in action within a narrative framework, making abstract rules more tangible and relevant. An experimental approach was adopted, with participants divided into two groups: a control group taught using conventional grammar exercises and an experimental group that used short stories to explore the same grammatical concepts. Both groups were assessed through pre- and post-tests, allowing for a direct comparison of their learning outcomes. Additionally, a survey measuring student engagement and motivation was administered to both groups. The results demonstrate that learners in the experimental group showed significant improvement in their understanding and application of grammatical structures compared to the control group. Furthermore, students in the experimental group reported higher levels of engagement and motivation. The study’s findings suggest that integrating short stories into grammar instruction not only improves language retention but also fosters a more dynamic and interactive learning environment. This research offers a practical framework for educators looking to enhance grammar teaching through literature, providing insights for more effective language pedagogy.

The craving for sweets is a universal desire that connects people of all ages and cultures. Traditionally used sweeteners based on sugars, such as sucrose or glucose-fructose syrup, are known for their multidirectional negative impact on human health. With the development of research into artificial sweeteners and natural sucrose alternatives, more and more consumers are turning to healthier options to satisfy their sweet tooth. Among the potential new sweeteners of natural origin, dihydrochalcones deserve special attention. These compounds belong to polyphenols and are present in plants. In the daily diet of people, their source may be citrus fruits, strawberries and apples. Dihydrochalcones, like other polyphenols, have a high and diverse health- promoting effect, e.g. antioxidant, antimicrobial or anticancer. Unfortunately, their extraction from plant material is challenging and economically unprofitable. The article presents a brief description of traditionally used sweeteners based on sugar, as well as alternative sweeteners. Methods for the chemical synthesis of dihydrochalcones are presented here, and the biotransformation processes involved in producing these sweet-tasting compounds are discussed

he energy and structure of intermolecular hydrogen bonds between water molecule and N-methylamide (NMA) or uracil (U) are discussed on the basis of DFT calculations. Theoretical methods are applied to calculate properties of cis- and trans- NMA complexes with one water molecule. Subsequently, H-bonds in six uracil – water complexes are analyzed. The influence of dispersion interactions and the polar environment on the hydrogen bond energy was analyzed. Results obtained by B3LYP functional with and without Grimme D3 dispersion correction indicate that dispersion interaction plays a significant role in an association process. In addition, the polar solvent reduces the hydrogen bond energy and this reduction is directly proportional to the hydrogen bond energy.

Biomembranes, which are the structural and functional basis of the cells of all living organisms, have been an extremely interesting research object for biology and chemistry scientists for years. The multitude of elements constituting the components of natural lipid membranes, however, is associated with interpretation difficulties regarding the nature of the processes taking place in them. A useful research object that is a model of bilamellar biosystems with a significantly simplified composition and at the same time retaining properties that can be a reference point in relation to natural membranes are lipid membranes in the form of one or several component liposomes. It is precisely such systems built of molecules of dipalmitoyl phosphatidylcholine (DPPC) or dipalmitoyl phosphatidylglycerol (DPPG), and analogous systems with the addition of cholesterol (Chol), that were the subject of research in this work. Near-infrared (NIR) vibrational spectroscopy provides a suitable method for the study of the hydrated samples. In most cases it can be alternatively adopted instead of commonly used mid-infrared (MIR) vibrational spectroscopy. This technique was applied for the first time to identify the spectral changes associated with the conformational changes in the hydrophobic region of model lipid bilayers. Trans/gauche isomerization of CH2 groups of lipid hydrocarbon chains is accompanied by characteristic changes in spectral parameters of both νas,s CH2 bands and their first overtones (2νas,s CH2). The heating of all types of analyzed liposomes results in main phase transition (Tm) accompanied by trans to gauche isomerization of CH2 groups of lipid hydrocarbon chains. The NIR-spectroscopy was able to describe in proper way (similar to MIR results) the character of Tm in studied bilayers.

he natural environment and living organisms that surround us are made up of chemical compounds, called chromophores, which can absorb photons coming from UV light from the Sun. The one-photon absorption process leads to ultrafast alteration in the electron density of chromophores, resulting in the population of short-lived excited states. These UV-induced electronic states can be responsible for performing high-energy chemical reactions, which cannot be observed in the chemistry of the ground state. Consequently, photochemical processes could damage the initial structure of a chromophore or allow molecules to undergo the chemical transformation to photoproducts. Therefore, understanding the photochemical and photophysical properties of essential chemical molecules for biology, medicine, renewable energy, and other fields is crucial to improve and find applications of light- sensitive systems in daily life. To scrutinize UV-induced chemistry, time-resolved spectroscopy is widely used as an experimental tool to investigate photochemical events. However, the experimental approach cannot provide detailed information about the molecular mechanisms of photochemical processes that occur in the excited states. Therefore, experimental methods in conjunction with computational photochemistry are used to elucidate the behaviour of UV-excited chemical molecules. Only the synergistic approach can comprehensively describe the photochemical picture of UV-induced molecules. This concise review contains a short introduction to the applications of computational chemistry in the studies of the photochemical properties of chromophores, and major radiationless deactivation pathways occurring in heteroaromatic compounds are briefly discussed. Furthermore, two very recent achievements of joint experimental and theoretical photochemistry studies are outlined, demonstrating how solvent or solute molecules can actively participate in photorelaxation channels of chromophores, allowing for an excited- state intermolecular electron transfer mechanism. The selected and discussed research results show that computational chemistry plays an invaluable role in answering questions about molecular mechanisms in the excited states and enables prediction of unexpected chemical processes

Linear poly(silsesquioxanes) (LPSS) of ladder-like chains are the least studied and understood group of macromolecular organosilicon compounds. However, the development of new analytical techniques has made it possible to design efficient synthetic methods to obtain polymers with a regular structure of the main inorganic component. As a result, a wide range of LPSS with different molecular weights and diverse organic functional groups have been obtained. The first part of this summary reviews the various methods of LPSS synthesis, along with a discussion of the basic factors controlling the structure of the siloxane chain. The valuable physical and chemical properties of linear poly(silsesquioxane) polymers resulting from the presence of a double siloxane chain make these polymers unique. Applications of LPSS in advanced materials engineering are presented and discussed.

In 1914, the second Radium Institute, after the Vienna Institute, was established in Paris. Maria Skłodowska-Curie became its director. It was a perfectly organized scientific and research facility. Almost immediately, the famous scientist began to think about creating a similar facility in Poland. Originally, the Radiological Laboratory was established in 1913 and was headed by Madame Curie from Paris. Madame Curieʼs dream became real only in the 1920s. The Radium Institute was opened in May 1932. It was the largest facility of this type in the world – it had a modern hospital and scientific and research facilities. The Radium Institute, as the Maria Skłodowska-Curie National Institute of Oncology, operates dynamically to this day
SMEs’ Access to Bank Financing During the Financial Crises in Europe
Authors: Ghulam Yaseen , Hakro Ahmed N. , Naumani Oumaima
Published: January 2025

This study explores the impact of the economy, banking market, and firm-specific factors on bank loan access for small and medium enterprises (SMEs) using data extracted from the Survey on the Access to Finance Enterprises (SAFE), covering the periods of the European sovereign debt crisis and the immediate post-crisis period from 28 European countries. We find that the rejection rates of bank credits spiked between 2009 and 2012 before declining in subsequent years. SMEs’ applications are more likely rejected when the banking environment is more concentrated but are less discouraged from applying due to rising impaired loans of banks. Credit availability is significantly influenced by the country’s legal framework for handling insolvency disputes and the growth of the credit information market, as we find that longer insolvency resolution times and increased credit information sharing result in higher probabilities of bank credit rejection. We also find that a feeble real economy is correlated with a more constrained credit supply and a shakier credit demand. More importantly, we build and subsequently empirically test hypotheses about factors determining credit demand and supply as well as the discouragement of SMEs in seeking bank loans, and the impact of past: rejections of bank credit, perception of deteriorations in banks’ loan availability, and bank loan application, on the deterioration of current credit supply perceptions, future applications, and future rejections, with significant lessons for policy making.

The advent of cloud computing and the Internet of Things (IoT) has facilitated the ability of medical practitioners to remotely monitor patients in real-time, thus enabling the provision of healthcare services in the comfort of patients' homes. To streamline this process, it is imperative to keep patient medical data in the cloud. However, storing medical information in the cloud poses a security risk due to the possibility of cyberattacks. As a result, the effective worldwide adoption of intelligent healthcare systems relies on a strong security mechanism. In addition, the use of restricted resources in health devices in IoT-enabled healthcare systems requires the installation of a combination of steganography and cryptography to protect these applications. The amalgamation of steganography and encryption diminishes susceptibilities and poses a formidable obstacle for trespassers attempting to get access to confidential data. This work proposes a security system that utilises the Diffie and Hellman algorithm for secret key sharing, as well as the Least Significant Bit (LSB) steganography principle and Deoxyribo Nucleic Acid (DNA) cryptography for encryption and decryption. The system is implemented using MATLAB 2018a tools. An evaluation is conducted on the encryption time, throughput, Peak Noise to Signal Ratio (PSNR), and Mean Square Error (MSE) of the proposed system. The suggested system has superior security and efficiency compared to the Advanced Encryption Standard and LSB algorithms, as confirmed by the performance evaluation.

Authors: N Kosala , V Nirmalrani
Published: January 2025

The analysis of user-generated content, such as product reviews on platforms like Amazon, is critical for understanding consumer sentiment. However, the unstructured nature of these reviews poses challenges for accurate sentiment analysis (SA). This study examines the influence of different preprocessing techniques on the effectiveness of sentiment analysis utilizing three feature extraction methods: BERT, TF-IDF, and GloVe. We evaluated the effectiveness of these techniques with machine learning classifiers such as: Logistic Regression (LR), Random Forest (RF), Naive Bayes (NB), and Extreme Gradient Boosting (XGBoost). Our findings indicate that preprocessing significantly enhances classification accuracy, particularly for models using TF-IDF and GloVe features, while BERT-based models showed robust performance even with minimal preprocessing. By combining BERT with preprocessing techniques, we attained an exceptional accuracy rate of 98.3% in sentiment analysis. This underscores the significance of meticulous data pretreatment in this field. These insights enhance the creation of more efficient sentiment classification algorithms, providing reliable information from Amazon product reviews.
Blockchain-Enabled Security Enhancement for IoT Networks: Integrating LEACH Algorithm and Distributed Ledger Technology
Authors: Oh Taeyeon
Published: January 2025

The rapid proliferation of Internet of Things (IoT) networks has significantly advanced various sectors such as smart cities, healthcare, and industrial automation, but it has also introduced substantial security challenges. Protecting data integrity, confidentiality, and availability in these networks is critical, yet traditional security measures often fall short due to the decentralized and resource-constrained nature of IoT devices. The Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol, designed to optimize energy consumption in sensor networks, lacks intrinsic security features. To address these challenges, this paper proposes a novel approach that integrates LEACH with Distributed Ledger Technology (DLT), specifically blockchain. Blockchain’s decentralized and immutable ledger can enhance data security and integrity within IoT networks. The methodology involves modifying LEACH to incorporate blockchain for secure data transmission. In the clustering phase, LEACH forms clusters and designates a cluster head (CH) for data aggregation and transmission. Each CH maintains a local blockchain to log and verify data transactions within its cluster, using a consensus mechanism to ensure data integrity. Smart contracts are implemented to automate security policies and detect anomalies, while data encryption and digital signatures provide additional security layers. Simulations using the NS-3 simulator showed promising results: energy consumption was reduced by 18% compared to traditional LEACH, latency increased by 5% due to blockchain processing overhead, throughput improved by 12%, and security metrics indicated a 25% improvement in data integrity and a 30% reduction in successful attack attempts. In conclusion, integrating the LEACH algorithm with blockchain significantly enhances the security and efficiency of IoT networks. This approach leverages the energy optimization of LEACH and the robust security framework of blockchain, offering a scalable and secure solution for diverse IoT applications. Future research will focus on optimizing blockchain operations to reduce latency further and exploring the model's applicability in various IoT scenarios.

Published: January 2025

Improved greenhouse Crop Yields (CY) are now within reach due to the rise of "Smart Farming (SF)" based on the Internet of Things (IoT). The IoT presents a massive opportunity for precision farming, which has the potential to increase CY, optimize resource use, and decrease the environmental impact of agriculture. Kenya's climate challenges greenhouse CY, but this paper lays out an integrated model that works well for growing Capsicum there. A multi-layered system equipped with sensors allows for the real-time monitoring of critical Environmental Factors (EF) in the model. For faster responses and less dependence on distant cloud services, these sensors send data to a processing layer that acts as an intermediary and uses Edge Computing (EC) for data management and immediate action. The analytics layer successfully reads sensor data, predicts possible scenarios, and makes decisions using Random Forest (RF) algorithms to improve crop productivity and yield. Also, the framework's user-friendly interface integrates data display and control, enabling efficient human communication. Kenya's climate impedes the cultivation of horticultural crops. The current study demonstrates that a hybrid model using IoT + EC + RF substantially improves Capsicum growth. The research establishes a standard for SF operations by combining advanced data analytics with the IoT to demonstrate how to develop a sustainable and adaptive SF system. This research set the standard for SF production by proving how a dynamic SF environment can be developed by applying advanced analytics with IoT.

Recent studies in clinical studies have observed a rampant increase in the rate of heart attacks, even among the newer population. Medical experts compute a multitude of factors as origins of a heart attack. But, the medical community is not able to explain the exact reasons for the prediction of heart attacks. ML algorithms are now evading the healthcare sector to assist healthcare providers in diverse ventures. This work analyses the potential causes of heart attacks among different age groups besides predicting attacks from biological conditions. The proposed ensemble model constellates the prowess of Support Vector Machine (SVM), K-Nearest Neighbors (K-NN), Random Forest (RF), and Extreme Gradient Boost (XGB) to predict heart attacks. The performance of this ML is tested on a heart attack prediction dataset, and the results promise the model's power over its peers. The proposed system achieved a classification accuracy of 92.8% for the test set in the ensemble model.
