Secure Storage System Using IPFS and Oracles for Blockchain-Based Decentralized Applications
Authors: García-Cereijo Pedro , Fraga-Lamas Paula , Fernández-Caramés Tiago M.
Published: February 2025

This paper presents a decentralized architecture that uses an oracle for file uploading to IPFS (InterPlanetary File System) via smart contracts for blockchain-based decentralized applications (dApps). The combination of a blockchain and IPFS provides an efficient and secure solution for data storage, ensuring immutability and traceability, while IPFS provides distributed storage. Since blockchains cannot interact directly with external systems like IPFS, an oracle is proposed as a bridge for such an interaction. This solution is designed and validated in a realistic scenario, demonstrating its effectiveness by enhancing security and efficiency when storing data in IPFS and only recording critical information on the blockchain, ensuring integrity through its immutability.

Published: February 2025

This paper presents the development of a system designed to collect, process, and visualize wearable health data using the Google Fit API. The system enables users to access their personal health metrics, such as step count, heart rate, and sleep patterns, while also offering personalized content and recommendations based on these metrics. Additionally, the system supports healthcare researchers by providing an AI-driven interface that translates natural language queries into SQL, allowing for efficient data retrieval and analysis. While the system leverages the broad compatibility of Google Fit, it also faces limitations due to its dependence on a third-party service, which could be affected by changes or discontinuation of the API. To mitigate the risk of errors in AI-generated queries, an exhaustive training process is required. However, the relatively simple database schema and limited query complexity help reduce the potential for significant errors. This system offers a practical tool for both personal health monitoring and research applications, with future work aimed at improving automation, resilience to external changes, and data query accuracy.

Land is an important need for human life, because land is a source to meet the needs of people’s lives and is a source of gifts from God Almighty. The increasingly limited amount of land has an impact on increasing land problems or disputes that occur, including land that has been registered with the National Land Agency and has been certified. Example of a case studied is the falsification of a land statement by Atang for land belonging to his late parents which has been sold and has been certified in the names of David Gunawan, Tony Tjahjadi, and Rina Gunawan.
This study uses a normative legal approach with analytical descriptive research specifications. Analysis of the data used in this study is qualitative normative. The data collection techniques used in this research is documentation studies.
The results of the study concluded that land statement are no longer a mandatory requirement and are no longer needed in the process of applying for land rights registration, but this is not stated explicitly. The Village Office itself has a very important role in issuing various types of letters related to land rights ownership and is the responsibility of a Village Head. The author can provide suggestions: first, the Government should review the regulations that emphasize the elimination of land statement requirements in applications for land rights registration. Second, the Village Office and Village Head must always be more careful in issuing letters, especially letters of information relating to land ownership, so as not to cause new problems.

Published: February 2025

Objective: This study aimed to examine the vascular access routes used by patients undergoing hemodialysis treatment in our province and determine the prevalence of arteriovenous (AV) fistula use.
Methods: Patients who were receiving regular hemodialysis treatment in Burdur province as of April 2024 were included in the study. Data on patients' age, gender, comorbidities, duration of dialysis, type of vascular access, and history of hemodialysis access were retrospectively reviewed and recorded using electronic patient records.
Results: The mean age of 197 patients evaluated in the study was 62.48±14.13 years. Of the patients, 63 (32%) were female and 134 (68%) were male. Hypertension was the most common comorbidity in 61.9% of the cases. The number of patients receiving hemodialysis treatment through an AV fistula was 136 (69%). The mean age of patients receiving treatment via an AV fistula was significantly lower than those receiving treatment via an indwelling hemodialysis catheter (P=0.011). Among the patients treated with an indwelling hemodialysis catheter, 59% had no history of AV fistula surgery. The mean age of patients without a history of AV fistula surgery was statistically significantly higher than those with a history of AV fistula surgery (69.28±14.98 vs. 60.96±13.52, respectively; P=0.001).
Conclusions: This study shows that one out of every two patients undergoing hemodialysis through an indwelling hemodialysis catheter has no history of AV fistula surgery. Reaching these patients and prioritizing AV fistula planning is crucial for achieving long-term success in hemodialysis treatment and reducing complications.

Authors: Şeker Gül , Orhan Özhan
Published: February 2025

Objective: The aim of this study was to examine the diagnostic profiles of patients admitted to pediatric gastroenterology, hepatology, and nutrition outpatient clinics within the scope of the state service obligation and to determine the reasons for inappropriate referrals.
Methods: A total of 10,235 patients admitted to the pediatric gastroenterology, hepatology and nutrition outpatient clinics of Mardin Training and Research Hospital between 2022 and 2023 were retrospectively analyzed. Data were analyzed using SPSS 21.0 software according to demographic and clinical variables such as age, gender, reasons for admission and diagnoses.
Results: Of the patients examined, 49.1% were girls and 50.9% were boys, and the most common reason for presentation was inadequate weight gain with a rate of 46%. However, malnutrition or another nutritional disorder was not detected in 28% of the patients referred with a diagnosis of inadequate weight gain. Malnutrition was diagnosed in a total of 1,710 cases, of which 8.2% were mild malnutrition, 5.3% were moderate malnutrition, and 4.2% were severe malnutrition. No pathological findings were found in 40.8% of the applicants. It was also found that most of the complaints of constipation and diarrhea, which are common reasons for admission, can be effectively treated in primary and secondary health care services.
Conclusions: The results of the study show that a significant proportion of referrals to pediatric gastroenterology outpatient clinics are unnecessary and that referrals can be reduced by evaluating these patients in primary and secondary care, thereby increasing the efficiency of health care services.
The effect of accessibility to acid sites in Y zeolites on ring opening reaction in light cycle oil hydrocracking
Authors: Yang Ping , Yan Siyang , He Ning , Nie Hong , Guo Luyao , Xiong Guang , Wang Naixin , Liu Jiaxu , Li Mingfeng
Published: February 2025

The light cycle oil (LCO) hydrocracking process converts polycyclic aromatics into highly valuable light aromatics such as benzene, toluene, xylene (BTX), in accordance with the requirements of low-carbon development and high-quality transformation from oil refining to chemical industry. The accessibility of acid sites is a critical factor that impacts LCO conversion and BTX yield. Initially, the fine structure and molecular size of the typical polycyclic aromatics in LCO and their hydrogenation reaction intermediates were investigated through gas chromatography-mass spectrometry (GC-MS) analysis and density functional theory (DFT) calculations. Three porous Y zeolites with comparable Si/Al molar atomic ratios and pyridine (Py)-measured Brønsted acid amounts were chosen as an acidic component to prepare NiMo/(Al2O3 + HY) catalysts. The acid accessibility of HY zeolite was characterized via dual-beam infrared spectroscopy using 2,4,6-tri-tert-butylpyridine (2,4,6-TTBPy) and trihexylamine (THA) as probe molecules, and the LCO hydrocracking performance was evaluated on a fixed-bed reactor. The results revealed that bicyclic aromatic hydrocarbons featuring multiple, short side chains such as dimethylnaphthalene and trimethylnaphthalene are the main components of LCO, with sizes larger than those of HY zeolite micropores. There is a strong positive correlation between LCO conversion and ring-opening rate of polycyclic aromatics and cycloalkanes in LCO. Among these three HY zeolite catalysts, the ring-opening rates of polycyclic aromatics and cycloalkanes, and the yields of C6-C12 aromatics and BTX increased in the order of HY1 < HY2 < HY3, which is consistent with external surface acidity measured by THA as the probe molecule.
Biomass burning enhanced human exposure risks in the context of global warming
Authors: Peng Zezhi , Sun Jian
Published: February 2025

In the context of global warming, biomass energy is gaining popularity due to its perceived carbon neutrality. However, the pollutants emitted during biomass combustion and the associated human health concerns are often overlooked. The increased frequency of heatwaves and wildfires contributes significantly to carbon dioxide and particulate matter (PM) emissions, posing substantial risks to public health. Furthermore, the greening of high-latitude regions as a result of global warming has increased the availability of biomass for local use. However, incomplete combustion of this biomass can lead to indoor air pollution and heightened health risks. Additionally, more frequent cold waves increase the demand for space heating, leading to increased household biomass burning, which raises exposure risks, especially in low- and middle-income countries. It is, therefore, essential to focus on human exposure risks associated with biomass burning, particularly from pathways not typically emphasized in the context of global warming.
Design of Fe2Mo@γ-GDY triatomic catalyst for electrocatalytic urea synthesis of N2 and CO: a theoretical study
Authors: Chi Linyuan , Wang Tonghui , Jiang Qing
Published: February 2025

While urea is widely used as a chemical raw material, its precursor ammonia (NH3) has traditionally been synthesized under high-temperature/pressure conditions, leading to not only huge energy consumption but also serious CO2 emission. Here, we present a groundbreaking catalyst design approach, which optimizes adsorption configurations and reaction pathways by controlling the adsorption energies of each intermediate in the reaction, thus enhancing catalytic performance. Via density functional theory (DFT) calculations, we designed a triatomic catalyst [i.e., Fe2Mo@γ-graphdiyne (γ-GDY)] with a limiting potential of -0.22 V and a C-N coupling energy barrier of 0.34 eV. Notably, the Fe2Mo@γ-GDY catalyst presents a high selectivity and robust antioxidation capabilities under applied potentials. Our comprehensive analysis elucidates the factors affecting the limiting potential and C-N coupling energy barrier. These insights significantly contribute to the advancement of catalyst design strategies for electrocatalytic urea synthesis, offering a more efficient and eco-friendly alternative to traditional methods.

Russia in the South Caucasus Gas Markets
Authors: Davtyan V.
Published: February 2025

The article analyzes the features of Russia’s interaction with the states of the South Caucasus (Azerbaijan, Armenia, Georgia) in the gas transportation sector. The study of the structure of the markets of the South Caucasian republics allowed us to determine the share of natural gas supplied from Russia, to assess the problems and prospects for further supplies. In recent years, there has been an increase in imports of Russian natural gas to the states of the region, which is caused by both economic and some geopolitical reasons, the identification of which is the purpose of this article. Russian natural gas is exported to the states of the South Caucasus via two gas pipelines – North Caucasus – Transcaucasia (Russia–Georgia–Armenia, Mozdok–Tbilisi–Yerevan) and Baku–Novo-Filya (Russia–Azerbaijan). The study of the characteristics of these gas pipelines allowed us to most comprehensively assess the possibilities of developing gas transportation communications between Russia and the states of the region. In the same context, we should consider the Iran-Armenia gas pipeline, which, although geographically has no outlet on Russia, is nevertheless the property of the Russian state company Gazprom. The high transit potential of the South Caucasus facilitates the development of gas transportation infrastructures here, aimed at forming international energy corridors North–South and East–West, which is today significantly hampered by the unresolved nature of a number of military and political conflicts in the region. At the same time, Russia’s interaction with the states of the South Caucasus in the energy and, in particular, gas transportation spheres demonstrates sensitivity to geopolitical processes, which is natural, given the dynamically changing security architecture of the region and attempts of a number of extra-regional actors, including the U.S. and the EU to increase their influence in the region. This dictates the need for Russia and the South Caucasus states to develop a strategy of energy diplomacy aimed at creating sustainable and secure gas transportation communications.
Terrorist Networks of the “Global Jihad” in the 2020s: New Forms, Locations and Challenges
Authors: Yashlavskii A.
Published: February 2025

Despite the heavy damage inflicted on transnational jihadist terrorist networks in the 2010s and 2020s, extremist groups acting under the banner of “global jihad” (primarily the Islamic State and Al-Qaeda) have not only survived, but also demonstrate the ability to adapt to new conditions and still pose a huge threat at different levels in various parts of the world. Terrorist networks have temporarily retreated into the shadows, trying to regroup their forces and find new fields and opportunities for their extremist activities. There are reasons to fear that we may be talking about the “calm before the storm”. A characteristic feature of modern transnational Islamist networks is the expansion of geography, primarily at the expense of African countries. Also, the “Afghan branch” of the Islamic State group (ISKP), which is not limited to the territories of Afghanistan and the countries bordering it, is showing special operational and propaganda activity. The expansion of the geography of terrorist networks is reflected in the evolution of their internal structure (which is especially evident in the example of the development of the management system of the “branches” of the IS network). The article also examines the impact of the war in the Gaza Strip on the activities of transnational jihadist networks. The author concludes that as long as the causes contributing to the growth of religiously motivated extremism and terrorism remain, global jihadist networks will continue to exist using various forms of hybrid warfare (terrorist acts, sabotage and guerrilla activities, seizure of territories for more or less long periods, propaganda war, recruitment activities, undermining public peace, etc.). It is also logical to assume that transnational Islamist terrorist networks will continue to skillfully combine their global ambitions with a purely local agenda, which poses a threat to a number of specific regions. And an equally alarming sign is the ability of adherents of the “global jihad” to use international conflicts for their own purposes.
The Return of the Taliban to Power as a Factor in the Transformation of Threats and Challenges to Regional Security
Authors: Makhmudov R.
Published: February 2025

The article addresses the issue of the emergence of new challenges and threats to the regional security system in Central and South Asia following the return to power of the Taliban movement in August 2021. Among them is the Taliban’s active policy in constructing the Qoshtepa canal related to the Amu Darya in northern Afghanistan without coordination with the Central Asian countries, posing a threat to the water, environmental, and food security of extensive areas in Turkmenistan and Uzbekistan. The complicating factor is the deterioration of relationship between the Taliban and Pakistan after 2021, rooted in contradictions surrounding the Kabul-non-recognized Durand Line, which divides the territory inhabited by many Pashtun tribes and clans on both sides of the Afghan-Pakistani border. An irritant in Afghan-Pakistani relations has been the increased terrorist activities of the Tehrik-e-Taliban Pakistan (TTP) following the establishment of the Islamic Emirate of Afghanistan, which has resulted in numerous casualties among Pakistani security forces and civilians. Islamabad accuses Kabul of harboring TTP militants on its territory, a claim refuted by the latter. In the long term, a challenge, primarily for a secular Central Asia, may be the Taliban’s antimodernist policy capable of influencing the growing post-secular trends in countries located north to the Amu Darya.

The coexistence of superconductivity and magnetism within a single material system represents a long-standing goal in condensed matter physics. Van der Waals-based moiré superlattices provide an exceptional platform for exploring competing and coexisting broken symmetry states. Alternating twisted trilayer graphene (TTG) exhibits robust superconductivity at the magic angle of 1.57° and 1.3°, with suppression at intermediate twist angles. In this study, we investigate the intermediate regime and uncover evidence of orbital magnetism. As previously reported, superconductivity is suppressed near the charge neutrality point (CNP) and emerges at larger moiré fillings. Conversely, we find orbital magnetism most substantial near the CNP, diminishing as superconductivity develops. This complementary behavior is similarly observed in the displacement field phase space, highlighting a competitive interplay between the two phases. Utilizing gate-defined Josephson junctions, we probe orbital magnetism by electrostatically tuning the weak links into the magnetic phase, revealing an asymmetric Fraunhofer interference pattern. The estimated orbital ferromagnetic ordering temperature is approximately half the superconducting critical temperature, coinciding with the onset of Fraunhofer asymmetry. Our findings suggest that the observed orbital magnetism is driven by valley polarization and is distinct from the anomalous Hall effect reported at integer fillings in twisted graphene systems. These results offer insights into the interplay between superconductivity and magnetism in moiré superlattices.

Published: February 2025

Introduction: Building a supportive and resilient healthcare workforce starts with educating health profession students. Health profession students need mental health literacy to be prepared to support themselves, each other and their future patients with mental health challenges. The aim of this study was to understand the current landscape of teaching and learning approaches to mental health education for undergraduate health profession students. Methodology: A realist review was chosen to explore what works for whom, how, and why in teaching and learning for mental health education for undergraduate health profession students. The search strategy was developed iteratively, with support from a research librarian, and additional searches supplemented the initial search. Following screening in duplicate, the selected studies were appraised for relevance, richness and rigour. Intervention (I), Context (C), Actor (A), Mechanism (M) and Outcome (O) configurations were extracted from the data and analysed for patterns and conceptual areas. Stakeholder and Patient and Public Involvement panels supported the refinement of both the Initial Programme Theory (IPT) and Programme Theories (PT). Results: 78 articles were included. There was evidence for a number of different teaching and learning approaches. The key themes identified were; direct contact with people with lived experience, longitudinal integrative approach to learning, and diversity of experiential and community engaged learning. Conclusion: Our realist review identified three critical programme theories for teaching and learning strategies that foster this literacy, including direct engagement with individuals who have lived experiences, a longitudinal and integrative approach to education, and a diverse array of experiential and community-engaged learning opportunities.

Published: February 2025

Background
The diagnostic accuracy of cancer detection for American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) 4 and 5 thyroid nodules remains insufficient, leading to overdiagnosis or misdiagnosis. The heterogeneity of microvascular distribution in thyroid nodules offers a potential avenue for differentiation. The aim of this study was to evaluate the feasibility and differential diagnostic value of quantitative ultrasound super-resolution imaging (SRI) for differentiating ACR TI-RADS 4 and 5 thyroid nodules by assessing the heterogeneity of microvascular distribution between intranodular and perinodular regions.
Methods
This prospective study analyzed contrast-enhanced ultrasound images from 33 pathologically confirmed ACR TI-RADS 4 and 5 thyroid nodules. Quantitative microvascular parameters, including vessel diameter, vessel tortuosity, microvascular density, and fractal dimension, were measured using SRI in both intranodular and perinodular regions. Univariate and logistic regression analyses were performed to evaluate the diagnostic performance.
Results
In benign nodules, no significant differences were observed between intranodular and perinodular regions for all measured parameters. In malignant nodules, both perinodular microvascular density and fractal dimension were significantly higher than intranodular values. Additionally, intranodular mean tortuosity and perinodular fractal dimension in malignant nodules were significantly higher than those in benign nodules. The combination of intranodular mean tortuosity and perinodular fractal dimension achieved an area under the curve of 0.835 (95% confidence interval: 0.692–0.977) for differentiating benign from malignant thyroid nodules.
Conclusion
Quantitative SRI effectively characterizes differences in microvascular distribution between intranodular and perinodular regions of benign and malignant thyroid nodules. Mean tortuosity within intranodular regions and fractal dimension within perinodular regions are promising ultrasound markers for the differential diagnosis of ACR TI-RADS 4 and 5 thyroid nodules.

Background
Stigma by association refers to the process by which individuals connected to someone with a stigmatized condition, such as caregivers of children living with disabilities (CLWDs), are themselves marginalized or discredited. In Sierra Leone, cultural beliefs frame certain disabilities, especially congenital or early-onset conditions, as curses or moral failings, leading to blame and a dual burden of social exclusion. This study explores how caregivers experience and respond to this dual form of stigma by association and the social support they encounter or desire.
Method
We conducted six focus group discussions with 37 caregivers of CLWDs in Freetown, Sierra Leone, recruited through hospitals and an NGO providing therapeutic services. Discussions were guided by a semi-structured interview protocol and analyzed using qualitative content analysis.
Results
Caregivers reported experiencing stigma by association through labeling, avoidance, societal blame, and coercion into traditional practices. Stigma was deeply rooted in cultural narratives that attribute disability to supernatural causes, often extending blame to caregivers. Participants employed three overarching strategies to navigate stigma: withdrawing, coping (e.g., spiritual reframing, focusing on positive interactions), and resisting (e.g., challenging superstitious beliefs, advocating for inclusion). Despite some positive experiences of empathy and social inclusion, caregivers expressed a strong need for more practical support, community awareness, and holistic interventions to reduce stigma and foster understanding.
Discussion
This study illuminates the complex interplay of cultural beliefs and social stigma shaping the experiences of caregivers of CLWDs. While caregivers demonstrated resilience and adaptive strategies, the dual stigma of association and societal blame underscores the urgent need for inclusive policies and community-based interventions. Amplifying the voices of caregivers and addressing their needs holistically are essential steps toward reducing stigma and creating supportive environments. This study contributes to the broader discourse on caregiving and stigma, offering insights for research and interventions in similar cultural contexts.

Background:
Malaria remains the leading parasitic disease worldwide with a significant global morbidity and mortality burden. Plasmodium malariae, the least prevalent of the five Plasmodium species that cause human malaria, has unique characteristics including prolonged prepatent periods, life-long persistance, and resistance to standard antimalarial treatments. In non-endemic countries and particular in neonates with coexisting diseases diagnosis and therapy pose challenges.
Case Presentation:
We report a rare case of severe congenital P. malariae malaria in a 2-month-old female infant born in Germany to a Nigerian mother. The infant presented with fever, hepatosplenomegaly, jaundice and respiratory distress. Initial workup revealed significant hemolysis, hepatopathy, and thrombocytopenia. Microscopic and PCR confirmed P. malariae. Shortly after the initial presentation, the infant developed clinical signs of cerebral malaria and organ failure, requiring invasive ventilation, anti-seizure medication, and vasoactive support. Following treatment with intravenous artesunate and oral atovaquone/proguanil, the infant showed significant improvement and was discharged after 36 days (22 days of paediatric intensive care) with a multidisciplinary follow-up plan. At six months post-discharge, she demonstrated stable organ function and mild developmental delay.
Conclusion:
The case highlights the diagnostic and therapeutic complexities of life-threatening congenital P. malariae infections in non-endemic countries. It underlines the importance of clinicians’ awareness of maternal travel or migration history and individualized treatment strategies. The increasing global mobility necessitates updated guidelines for congenital malaria management even for less likely P. malariae infections. Prophylactic measures, early recognition, and multidisciplinary management are critical for improving outcomes for such rare but severe presentations and their long-lasting complications. Possible comprehensive neonatal malaria screening in high-risk populations should be considered in the future.

The issue of surgical tactics for treating subcutaneous degenerative ruptures of the distal tendon of the gastrocnemius muscle is the disintegration of the tendon’s end, disruption of its sliding surface, resulting in the formation of adhesions with the synovial membrane, which significantly worsens long-term functional results. In experiments on animals previously conducted by the authors, results were obtained stating that the surfaces of xenopericardial plates are characterized by different properties. For villous - the ability to biointegrate, for smooth - intactness, without the formation of scars and adhesions. The article describes a clinical example of this phenomenon. Patient D., age 53 years, with a subcutaneous degenerative rupture of the Achilles tendon underwent Achilles tendon suture surgery with restoration of the sliding surface with a xenopericardial plate. In the postoperative period, 4 weeks after surgery, due to the patient’s violation of the load regime, a rupture of the suture area occurred. After repeated surgical intervention, it was established that the villous surface of the xenopericardial plate, facing the tendon, effectively underwent the process of biointegration, while the smooth surface, located on the side of the synovial membrane, retained its sliding surface. This clinical example demonstrates the advantage of original methods developed by a team of authors of the Department of Traumatology, Orthopedics and Military Extreme Medicine of PSU over existing traditional types of treatment.
