Enhancing Digital Citizenship Through Secure Identification Technologies in the Global Unified Digital Passport
Passports play a vital role in enabling international movement and security, as well as confirming one's identity. However, the existing passport system has many problems and limitations, such as identity fraud, passport falsification, human smuggling, terrorism, and border control. Despite the fast growth and adoption of digital technologies in various fields, the passport system has not been able to adapt to the changing demands and expectations of the global community. Therefore, there is a pressing need to investigate and develop a digital passport and verification system that can address the shortcomings of the conventional passport system and provide a more safe, convenient, and effective way of managing and verifying the identity and travel history of individuals across the world. This paper presents the solution and requirement for the development of a digital passport system that can be applied globally and universally. The paper proposes a conceptual framework and a technical architecture for the digital passport system, based on the principles of blockchain, biometrics, and cryptography. The paper also discusses the possible benefits, challenges, and implications of the digital passport system for various stakeholders, such as travelers, governments, airlines, and immigration authorities. The paper aims to contribute to the research and innovation of digital identity and citizenship, as well as to the progress of the sustainable development goals (SDGs) related to peace, justice, and strong institutions. 2024 IEEE. -

Direct ink writing of nickel oxide-based thin films for room temperature gas detection
The rapid industrial growth and increasing population have led to significant pollution and deterioration of the natural atmospheric environment. Major atmospheric pollutants include NO2 and CO2. Hence, it is imperative to develop NO2 and CO2 sensors for ambient conditions, that can be used in indoor air quality monitoring, breath analysis, food spoilage detection, etc. In the present study, two thin film nanocomposite (nickel oxide-graphene and nickel oxide-silver nanowires) gas sensors are fabricated using direct ink writing. The nano-composites are investigated for their structural, optical, and electrical properties. Later the nano-composite is deposited on the interdigitated electrode (IDE) pattern to form NO2 and CO2 sensors. The deposited films are then exposed to NO2 and CO2 gases separately and their response and recovery times are determined using a custom-built gas sensing setup. Nickel oxide-graphene provides a good response time and recovery time of 10 and 9 s, respectively for NO2, due to the higher electron affinity of graphene towards NO2. Nickel oxide-silver nanowire nano-composite is suited for CO2 gas because silver is an excellent electrocatalyst for CO2 by giving response and recovery times of 11 s each. This is the first report showcasing NiO nano-composites for NO2 and CO2 sensing at room temperature. 2025 Chinese Institute of Electronics. -
Mathematical Capabilities of LLMs
Large language models (LLMs) have the potential to solve mathematical problems well, but little has been investigated. In this research, we evaluate five leading LLMs - (Gemini, Claude, Mistral, ChatGPT, and Llama - on a set of 50 mathematical problems that cover calculus, algebra, geometry, number theory, and probability. Finally, the study evaluates the accuracy of their solutions and gives the ability to assess their intermediate steps correctly. I created a primary dataset for comparison of the LLM performances and ranked the models according to how well they were able to solve those problems. It illustrates the shortcomings of present LLMs at reasoning and solving for mathematics and suggests what needs to be rectified in the LLMs. Future research will further refine this dataset and monitor the progression of LLM capabilities in solving more complex mathematical problems. 2025 IEEE. -
Targeting Metabolic Reprogramming: A New Frontier in Cancer Therapy
Cancer cells undergo profound metabolic reprogramming to meet the high demands of unchecked proliferation within the nutrient-limited tumor microenvironment (TME). While fundamental metabolic pathways are conserved, cancer cells exhibit distinct metabolic fluxes and substrate preferences, meticulously dictated by genetic, epigenetic, and microenvironmental cues that reshape enzyme and transporter profiles. This metabolic rewiring sculpts the TME, fostering both competition and cooperation, often favoring tumor-promoting stromal components (cancer-associated fibroblasts, M2 tumor-associated macrophages), and hinders antitumor immunity. Targeting aberrant cancer metabolism and originating interactions in TME presents a promising therapeutic avenue. However, the inherent metabolic heterogeneity across malignancies necessitates personalized combination therapies and continued research to efficiently target this key cancer hallmark. 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. -
A Hybrid Ensemble Model Combining Machine Learning and Fuzzy Logic for Robust Stress Level Detection
Accurate stress detection remains challenging because stress manifests differently across diverse populations. This research presents a novel hybrid approach that combines four machine learning classifiers - XGBoost, Random Forest, Support Vector Machine, and Logistic Regression - with an enhanced fuzzy logic system through weighted voting. The study employed a comprehensive dataset comprising over 1,100 samples containing more than 45 features that capture psychological, academic, social, physical, and environmental stress indicators. The results demonstrate that the ensemble achieves 87.27% accuracy with statistically significant improvements over individual models (p0.001). The approach maintains strong performance when 10% noise is injected or missing data is simulated, and provides well-calibrated probability estimates that could support clinical decision-making. 2025 IEEE. -
Evidence-Based Interventions for Improved Psychosocial Outcomes in Harmful Alcohol Use: A Scoping Review
Background. Harmful alcohol use is defined as a drinking pattern that lasts at least one month or has occurred often during the preceding 12 months and that negatively impacts multiple facets of life. It has a high recurrence rate and a poor prognosis, despite the availability of cognitive-behavioral and psychosocial therapy. Emerging neuromodulation techniques for treating harmful alcohol use are gaining traction in the field of psychotherapy, but knowing their efficacy in terms of psychosocial outcomes necessitates an adjuvant approach. This scoping review aims to investigate the existing evidence on the effectiveness of various psychosocial interventions that improve quality of life (QoL) dimensions in conjunction with neurotherapies for individuals with harmful alcohol use. Methods. The review utilized a five-stage technique to search for research papers from 2000 to 2022. After screening and reviewing 41 full-text papers, 29 were found to meet the inclusion criteria. Conclusion. The articles highlighted the advantages of integrated therapeutic interventions such as motivation enhancement therapy, cognitive behavior therapy, neurotherapy, multimodal therapy, supportive therapy, and 12-step facilitation programs. However, limited studies have explored the effectiveness of combining neurotherapy with psychosocial interventions. Implications. Future research should focus on the efficacy of combining neurofeedback with psychosocial therapies to improve QoL for individuals with harmful alcohol use. 2024. Thakuria and Bennett. -
Economic resilience in the face of pandemic: a holistic mathematical analysis of the pandemic in India
COVID-19 was initiated in 2020 and caused an immediate threat to global countries in terms of both economic and health influences. In this present work, we extend the Susceptible-Infected-Recovered (SIR) model by considering two new variables, gross domestic product or GDP (G) and unemployment (U), to study the impact of this epidemic on the Indian economy during the 20202023 period. Since our extended SIR model includes two novel compartments, which are GDP and unemployment rate, we can now explore in more detail the sophisticated relationship between health and economic matters. The framework allows us to investigate the following consequences: how changes in the infection rate affect the economy and how changes in GDP and unemployment translate into the spread of this contagion. These visualizations are based on real-time quarterly data and provide full knowledge of the interaction between health and economic dynamics during the COVID-19 crisis in India. Government initiatives and regulations are also reviewed for their efficiency to contain the virus while taming the economic cost. Real-world results are contrasted with the care to find the strengths and weaknesses of the policies that come out with the underlying assumptions in the model. This paper, in other words, deploys an in-depth analysis of the convoluted links between economics, policy, and public health in the face of a pandemic with a geographic focus in India. 2025 by the authors. -

Identification of the Functional Limitation of Marine Loading or Unloading Arm; A Case Study
Marine loading or unloading arms are used to transfer product from tanker vessels that often carries products like petroleum or chemicals from or to the tankers. Cochin Port has dedicated Tanker jetties for handling petroleum with Marine Loading Arms installed for safe handling of cargo. However, my studies in Cochin Port Trust have shown that it has a potential threat to tackle while it is taken for the maintenance process. The case study aids in understanding of the working of marine unloading arm installed in the port and to identify the functional or safety limitations of the existing model installed. This case study also proves that a small change in the design can bring about a big change in the safety of the people working with the equipment. The identified parameters have been studied for providing the necessary alterations of the design which could be implemented on the upcoming project of constructing the marine unloading arm in Cochin Port Trust. To support faster and safety loading/unloading requirement these hydraulically operated marine loading arms are fitted with emergency release couplings and emergency release system. Marine Loading Arms are operated by using the hydraulic system. During maintenance procedure while checking the Emergency Release System (ERS) functionality, accidental release of Emergency release coupling can cause fatality. Hence a fool proof design is suggested with an extra locking arrangement. The studies conducted till now and the reviews conducted contributed in the analysis of the development and validation of the design. A design of a locking machanism for preventing the fatality is created and analysed for suggesting it to the industry so that it could be incorperated in the upcoming project of constructing the marine loading and unloading arm. 2023 American Institute of Physics Inc..
