A Framework for Securing Agentic AI Workflows and Quantum-Resistant Communication in U.S. Critical Infrastructure Networks
type: item
description: For artificial intelligence (AI) systems designed to learn and act without human intervention, the events of this rapid integration into U.S. critical infrastructure networks and the rapid pace of approach to cryptographically relevant quantum computers (CRQCs) create a dual convergence of threat that is not adequately met by current frameworks. Agentic AI systems have additional attack surfaces, such as prompt injection, non-human identity (NHI) exploitation, and cascading multi-agent failures, due to their ability to operate autonomously, take multiple steps, and coordinate with other agents. At the same time, existing public-key cryptographic standards, such as RSA and elliptic curve cryptography (ECC), are under attack with harvest-now-decrypt-later (HNDL) attacks to hack encrypted communications in operational technology (OT) and industrial control system (ICS) environments. This article suggests security in both threat domains by leveraging three layers of security: Layer 1: Security of the agentic AI workflow through identity management, prompt sanitization and behavior monitoring; Layer 2: Quantum resistant communication with migration to NIST standardized post-quantum cryptographic (PQC) algorithms (FIPS 203, 204, 205); and Layer 3: Governance and compliance integration with CISA, NERC CIP and the NIST AI Risk Management Framework. Compliance is verified with a cross-walk analysis to current standards, and the framework is tested in scenarios of representative critical infrastructure in the energy, water, and financial sectors. Results suggest that this framework offers a roadmap for RTOs to use in preparing for the deployment of agentic AI and the migration to post-quantum cryptographic algorithms.

A Leakage-Aware Machine Learning Pipeline for Credit Default Prediction Using LightGBM
type: item
description: Credit default prediction remains challenging because loan-outcome datasets are typically imbalanced, heterogeneous, and vulnerable to post-origination target leakage. This study proposes a leakage-aware and interpretable LightGBM-based credit-risk modelling framework for binary loan-status classification into Fully Paid and Charged Off/Default outcomes. The proposed workflow integrates rigorous target definition, removal of repayment-derived leakage variables, robust missing-value handling, outlier winsorisation, date-derived credit-history features, log-transformed monetary variables, affordability and utilisation ratios, mixed categorical encoding, FICO bucketisation, class-frequency reweighting, and mutual-information-based feature selection. A large lending dataset of 887,379 completed loans was analysed, comprising 725,223 Fully Paid loans and 162,156 Charged Off/Default loans. Data were stratified into training, validation, and holdout test sets using a 70/15/15 split, with additional stratified five-fold cross-validation repeated across five random seeds, yielding 25 validation runs.LightGBM was selected as the proposed best model after comparison with Logistic Regression, Random Forest, CatBoost, and XGBoost. The model achieved the highest mean cross-validation AUC of 0.762 ± 0.004, outperforming XGBoost, CatBoost, Random Forest, and Logistic Regression, which obtained AUC values of 0.758 ± 0.004, 0.755 ± 0.004, 0.731 ± 0.005, and 0.708 ± 0.005, respectively. On the independent holdout test set, LightGBM achieved an AUC of 0.764, accuracy of 0.853, default sensitivity of 0.730, specificity of 0.880, default F1-score of 0.644, positive predictive value of 0.576, negative predictive value of 0.936, and Brier score of 0.124. Feature-importance and SHAP-direction analysis identified interest rate, sub-grade, debt-to-income ratio, annual income, and FICO range as the dominant risk drivers.

A Survey of Next-Generation Electronic Quality Management Systems for Global Regulated Enterprises
type: item
description: Next-generation Electronic Quality Management Systems (eQMS) represent the evolution of traditional paper-based quality systems into intelligent, cloud-based, and compliance-driven digital ecosystems. This study examines the organizational architecture, regulatory alignment, enabling technologies, and implementation challenges associated with next-generation eQMS in regulated industries such as pharmaceuticals and advanced manufacturing. Modern eQMS platforms integrate core quality modules including document control, CAPA, audit management, training, and change control into centralized and automated systems that enhance traceability, data integrity, and operational efficiency. The paper further evaluates compliance with global regulatory frameworks, including ICH E6(R2/R3), USFDA 21 CFR Part 11, EMA Annex 11, and PIC/S guidelines, with a focus on inspection readiness and lifecycle-based validation. Emerging technologies such as artificial intelligence, machine learning, cloud computing, blockchain, digital twins, and the Internet of Things are enabling predictive, real-time, and proactive quality management. Despite these advancements, implementation remains challenging due to legacy system integration, data complexity, resource constraints, and organizational resistance to digital transformation.

Transforming Pharma Manufacturing Supply Chains Through AI and ERP Analytics
type: item
description: The pharmaceutical manufacturing business has a complex, international supply chain, constrained by strict regulatory measures, rising costs, and growing pressure on product quality, supply, and efficacy. Conventional planning and control strategies have not been effective at managing demand volatility, equipment reliability, and inventory risk at a large scale. To this end, artificial intelligence and enterprise resource planning systems are emerging as transformative technologies that can revamp supply chain processes in pharmaceutical companies. The next stage of analytics in demand prediction, predictive maintenance, inventory optimization, and production planning is reachable due to the integration of AI and ERP solutions, increasing the efficiency of operations and improving decision-making quality. Based on empirical data by proven pharmaceutical manufacturers, up to 30% of forecast errors, 20-30% of unplanned unforeseen downtime, and ten to 20% of holding inventory costs are reduced after AI-facilitated adoption of ERP. Nevertheless, it has to be well run in data governance, inter-functional collaboration, and change management to facilitate the effective use of the technologies and ensure the reliability of the models, regulatory compliance, and workforce acceptance. This paper combines the empirical evidence base in the industry, practical case study applications, and analysis findings to deliberate on the feasibility of AI ERP integration in the pharmaceutical manufacturing process. It suggests an analytics-driven decision-making model with governance to make supply chains more resilient.

A National-Scale AI-Driven Cyber Defense Framework for Protecting U.S. Critical Infrastructure Against Nation-State Attacks
type: item
description: The Cybersecurity and Infrastructure Security Agency (CISA) has predicted a 140% rise in high-impact attacks between 2022 and 2024, signalling an increase in nation-state adversary cyberattacks that affect US critical infrastructures. The sophistication, persistence and ever-evolving nature of nation-states' hacking has outgrown current cybersecurity, which primarily focuses on reactive and perimeter-based approaches. In this paper, we present and test a National-Scale AI-Driven Cyber Defense Framework (NAICDF) a multi-layer, intelligence-based framework with machine learning-based threat detection, federated learning for data sharing across critical infrastructure sectors, Zero Trust Architecture (ZTA) and automated response systems. We compare intrusion detection accuracy, mean time to respond (MTTR) and resilience with traditional approaches using incident reports of 847 confirmed nation-state intrusions in 11 critical infrastructure sectors (2020-2024), publicly available threat intelligence and simulation data from the National Cyber Exercise Program (NCEP) of the Cybersecurity and Infrastructure Security Agency (CISA). Results demonstrate the NAICDF achieves a 94.3% accuracy in detecting intrusions (2.1% false positives) and a 67% reduction in the mean time to respond (MTTR) when compared to conventional security operations center (SOC) systems. We also explore governance and public-private partnership models, and compatibility with existing policy frameworks such as CIRCIA (2022) and the National Cybersecurity Strategy (2023). The framework offers a policy-friendly, scalable model to secure our critical systems in the 21st century.

Strategic Framework for Zero-Downtime Modernization of Legacy Enterprise Systems
type: item
description: Legacy enterprise systems provide the stable foundation for mission-critical operations in large organizations, yet they frequently consume 70–80% of IT budgets and limit innovation. This paper presents a practical, proven framework that enables IT leaders to modernize these systems into cloud-native microservices while delivering true zero downtime, zero service disruption, enhanced resiliency, improved latency, and significant cost optimization.The framework is built on three primary architectural transformation strategies — the Strangler Fig Pattern, Domain-Driven Decomposition, and Blue-Green Deployment — supported by Change Data Capture (CDC), the Agile-to-Uplift (A2U) methodology, and targeted network upgrades. Together, these elements allow organizations to extract and migrate business functions incrementally with full confidence. A real-world financial services case study demonstrates complete modernization over 24 months with no customer impact and substantial annual savings.

Securing the Next Generation of Digital Payments: A Threat Model for Virtual Card Ecosystems
type: item
description: The rapid adoption of virtual cards in business-to-business (B2B) payments has created a complex digital ecosystem involving buyers, suppliers, issuers, acquirers, and increasingly, automated processing platforms. While virtual cards offer inherent security benefits, the ecosystem's interconnectedness and reliance on digital channels introduce a new and expanded attack surface. This paper presents a comprehensive threat model for this next generation of digital payments. Using the STRIDE framework, we systematically analyze the security threats inherent in the end-to-end virtual card lifecycle, with a particular focus on novel attack vectors targeting the automated data ingestion and processing stages of platforms like Visa AR Manager. Based on this analysis, we propose a multi-layered, defense-in-depth mitigation strategy. This strategy integrates foundational controls such as PCI DSS compliance, technical solutions including payment tokenization and secure API gateways, and advanced AI-powered fraud detection to create a resilient and secure virtual payment environment capable of withstanding modern threats.

Machine learning based clinical decision support for heart disease prediction using structured patient data
type: item
description: Heart disease remains a leading cause of mortality worldwide, necessitating reliable and efficient predictive models for early diagnosis and clinical decision support. This study presents a comprehensive machine learning framework for heart disease prediction using a structured clinical dataset comprising 920 patient records with diverse demographic, physiological, and diagnostic attributes. The dataset includes both numerical and categorical features, requiring careful preprocessing and encoding to ensure compatibility across different model architectures.A range of classification algorithms is systematically evaluated, including Logistic Regression, K-Nearest Neighbors, Decision Tree, Random Forest, Support Vector Machine, Extreme Gradient Boosting, and Light Gradient Boosting Machine. Model performance is assessed using multiple evaluation metrics, including accuracy, precision, recall, F1-score, and receiver operating characteristic area under the curve, along with five-fold cross-validation to examine stability and generalization behavior.The experimental results demonstrate consistently high predictive performance across most models, with several approaches achieving near-perfect classification metrics and minimal variation across cross-validation folds. In contrast, K-Nearest Neighbors exhibits slightly lower performance, highlighting differences in sensitivity to local data structure. Analysis of feature distributions and pairwise relationships indicates strong separability between classes, particularly driven by clinically relevant variables such as chest pain type, exercise-induced angina, ST depression, and maximum heart rate.Further evaluation using confusion matrices, receiver operating characteristic curves, and precision–recall curves confirms the robustness of the predictive models and their ability to distinguish between diseased and non-diseased cases with high reliability. Despite the strong performance, the study acknowledges potential dataset-sp…

A Secure and Privacy-Preserving Architecture for Web-Based Remote Learning Systems
type: item
description: The rapid proliferation of web-based remote learning systems (WBRL) has introduced critical security and privacy challenges that threaten the integrity of educational data and the confidentiality of student information. This paper presents SP-WBRL, a Secure and Privacy-Preserving architecture designed for web-based remote learning environments. The proposed multi-layered framework integrates advanced encryption standards (AES-256), role-based access control (RBAC), differential privacy mechanisms, and a zero-trust network model to provide end-to-end security. We formalize the privacy guarantees using (ε, δ)-differential privacy and derive theoretical bounds on information leakage. Extensive experiments conducted over a 12-week deployment with 2,847 participants across three institutions demonstrate that SP-WBRL achieves a 97.3% threat detection rate with only 6.8% average latency overhead compared to non-secure baselines, while maintaining FERPA and GDPR compliance. Comparative evaluation against five state-of-the-art systems shows significant improvements in security coverage (23.1% improvement), privacy preservation (31.5% improvement), and user satisfaction (92.4% approval rating). The results confirm that comprehensive security can be integrated into remote learning platforms without substantially degrading the user experience.

NLP Framework to Summarize p53–FBW7 Pathway Alterations and Associated miRNAs in CRC
type: item
description: The increasing intricacies of molecular pathways involved in CRC, especially focusing on the p53-FBW7 pathway network and the microRNAs (miRNAs) that regulate them, present significant difficulties when synthesizing knowledge from the exploding body of biomedical literature. Conventional methods of manual literature review have proven inadequate for capturing and analyzing such multidimensional interactions in a timely fashion. In this paper, we describe an innovative NLP-based approach for mining CRC-related pathway changes and miRNA interactions. The architectural framework uses domain-driven data extraction methods along with sophisticated pre-processing, named entity recognition using transformers, and relation extraction techniques to extract important biological entities and their relationships. The relations extracted by the framework are then encoded within a knowledge graph capturing pathway-level dynamics of gene-protein-miRNA relationships, which can provide an integrated perspective on gene-protein-miRNA relationships. Furthermore, the transformer-based summarizer also provides summarized insights related to p53-FBW7 axis. The model aims to bring together computational intelligence and molecular oncology through a comprehensive, automated, and interpretable process for knowledge integration in biomedical sciences. Expected benefits will involve greater efficiency in research, the ability to identify key regulatory mechanisms, and contributions to precision medicine and drug discovery initiatives. Despite being conceptual, the paper introduces a novel method that combines NLP with cancer pathways, holding promise for extensive development in the future.

Big Data Analytics Using Hadoop and Spark: Applications, Challenges, and Future Direction
type: item
description: Big data describes large datasets that are difficult to manage owing to their diversity, size, and complexity in terms of storage, analysis, and visualisation for future operations. Artificial intelligence (AI) based big data analytics have revolutionised the processing of massive data sets by leveraging distributed computing platforms like Apache Spark and Apache Hadoop. Both HDFS and MapReduce leverage the 5Vs of Hadoop—Volume, Velocity, Variety, and Veracity—to store files and perform batch analysis on massive, heterogeneous datasets. Spark expands upon these capabilities with libraries for graph analytics, streaming, machine learning, in-memory computing, and directed acyclic graphs (DAGs). This paper gives a general outline of the Hadoop and Spark ecosystem, as well as their architecture and how they are used in distributed machine learning, real-time analytics, NLP, and anomaly detection. It also addresses such critical issues as scalability limitations, data protection, resource administration, and complexity of infrastructures. Lastly, the future directions are discussed with a focus on cloud-native designs, edge computing, and hardware acceleration as well as intelligent resource optimization to improve the performance, efficiency, and flexibility of the next generation Big Data systems.

A 2025 survey by SRM University AP, published in the Asian Journal of Psychiatry, found that nearly 70 percent of 1,628 college students across eight major Indian cities reported moderate to high anxiety levels, while over 60 percent exhibited clinically significant depression symptoms. These numbers are not outliers. Cross-national data shows Japan at 80 percent stress prevalence, the United States at 67 percent, and Pakistan at 71 percent. What unites these figures is not geography but the structure of modern academic life: excessive workload, unrelenting performance pressure, financial strain, social comparison amplified by digital platforms, and institutional support systems that were simply not built for this scale of need. The clinical response to this crisis has been slow and resource-constrained. Counseling services are stretched thin. Most students who need help do not seek it, largely because of stigma, lack of awareness, or long wait times. Only 7 percent of college students in the United States access professional mental health support in any given year (EssayPro, 2025). This gap between need and access defines the problem this article addresses. This article presents a machine learning-based classification framework that predicts student stress levels across three tiers: low, medium, and high. The model draws on academic, lifestyle, physiological, and psychometric data collected through structured surveys. It evaluates five classification algorithms, including Logistic Regression, Random Forest, XGBoost, and ensemble methods, with accuracies ranging from 86.2 to 97.92 percent in peer-reviewed studies. The framework also includes a recommendation engine that generates targeted, evidence-based intervention guidance for each stress tier. The goal is to give educational institutions a practical, scalable tool for identifying students at risk before their stress reaches …

A Systematic Self-Review of Electronic Searching Studies (2002–2021): Training, Infrastructure, and Institutional Contexts
type: item
description: This study conducted a systematic review (SR) of the author’s research program on electronic searching published between 2002 and 2021. A total of seventeen studies were identified and organized into five thematic clusters: electronic information infrastructure, factors affecting electronic searching, electronic searching skills and training, integration of electronic resources in teaching and research, and policies, intellectual property, and e transformation. Together, these studies provide a comprehensive account of the conditions, competencies, and institutional arrangements that shape effective electronic searching in higher education contexts. Findings across the corpus indicate that successful electronic searching involves a combination of individual skill development, supportive institutional environments, and efficient technological infrastructure. Gaps in connectivity, system design, metadata quality, and resource availability directly influence users’ ability to locate and retrieve information. Fragmented databases, limited access to full text materials, and inconsistent archiving practices, were found to hinder researchers’ performance. Results also demonstrate that electronic searching skills do not emerge spontaneously but require explicit instruction, guided practice, and exposure to diverse digital tools that appear to consistently improve users’ confidence, accuracy, and efficiency. Training programs that emphasized search strategies, evaluation of digital sources, and searching specialized databases yielded noticeable gains among faculty, graduate students, and library staff. Additionally, integrating electronic resources into teaching and research both enhances and depends on improved searching practices. When electronic resources are embedded within coursework and research tasks, learners demonstrate stronger engagement and more sophisticated information handling behaviors. However, such integration is only effective when supported by institution…

Advanced Models & Multimodal Reasoning: A Conflict Resolution–Centric Architecture
type: item
description: Multimodal artificial intelligence has evolved at a fast rate, and currently, advanced models can process vision, language, audio, and sensor data on the scale and accuracy not seen before. Regardless of these developments, multimodal reasoning systems are not well adopted in the real-life context and high-stakes situations. This paper holds the view that the fundamental impediment is not perceptual performance rather than architectural weakness where there is disagreement between heterogeneous modalities. We suggest an architecture-first view where the conflict is not viewed as an exception and must be inhibited but is a normal feature of a multimodal system that must be dealt with explicitly. The key conceptual element of this school of thought is the Conflict Resolution Layer (CRL), which is a system-level architectural primitive that identifies, assesses, and resolves conflicts between expert models of specific specialization acting over common, time-based evidence. In contrast to end-to-end multimodal fusion methods or ensemble learning methods, the CRL will not only allow decision policies to be made deterministically, auditable, and by humans in the loop; it will also allow inference to be completely separated from arbitration. We give formalization and roles of the CRL, examine the performance features of the CRL, and demonstrate that conflict-conscious reasoning is more coordination-bound than it is compute-bound. The paper also shows how CRL-based architectures can facilitate incremental adoption of the industry, starting with advisory systems and then because of conditionally automated decision pipelines, all being vendor-neutral and hardware-agnostic. This contribution by highlighting shift of focus towards model-centric optimization to system level design establishes conflict resolution as a lacking architectural primitive to robust, interpretable, deployable multimodal reasoning systems.

From Monolithic Models to Cognitive Hives: A Framework for Multimodal Reasoning Systems
type: item
description: The increasing fast development of multimodal foundation models has greatly contributed to the development of artificial intelligence systems that have the ability to process and integrate text, vision, audio, and structured information in single architectures. Although they have been performing admirably, these models are becoming more limited in nature as they grow in size especially in performance regarding efficiency, transparency and flexibility. Existing monolithic multimodal architectures demand a lot of computational and financial resources, have inflexible structure of design, and are not that interpretable. Moreover, they also use implicit fusion processes that are blind to modal conflict and inconsistency detection and resolution. The given paper suggests another paradigm, known as cognitive hives, which views intelligent multimodal systems as distributed assemblies of specialised expert models instead of single end-to-end networks. The approach to multimodal reasoning, in this context, is viewed as an issue in distributed systems, in which autonomous domain-specific experts interact via shared representations and explicit coordination protocols. One of the main parts of the suggested architecture is a special conflict resolution layer that would identify, arbitrage, and clarify disputes between expert models. The major contributions that were made in this work are the formal definition of cognitive hive architecture, systematic approach on cross-modal conflict resolution, and analysis of deployment strategies, latency trade-offs and failure modes in distributed reasoning systems. The framework is proposed to be hardware-agnostic, modular and future-proof, and is a scalable and explainable alternative to monolithic multimodal models.

Regulating the Algorithmic Bloodhound: Modernizing US Financial Regulations for the AI Era of Counter-Terrorism
type: item
description: The issue of terrorist financing is a major threat to international stability, because rogue actors take advantage of vulnerabilities of financial systems to direct funds towards illegal operations. The U. The S. financial system, though highly regulated and robust, is still a prime target because of its complexity, size and accessibility. Structural frameworks of monitoring that are based on predetermined rules and thresholds are usually ineffective in identifying advanced ways of hiding the money through structuring, layering, and distributing the money on a variety of accounts. This study examines how artificial intelligence and data analytics can be used to enhance counter-terrorist financing actions by exposing concealed patterns of financial transactions. With the PaySim dataset, which is a massive synthetic dataset of mobile money transactions, the study examines how such fraudulent behavior, as a proxy of terrorist funding, can be identified using sophisticated computational methods. This data offers very useful transaction-specific information, such as account balances, the types of transactions, and red flags of suspicious behavior, allowing the creation of models that detect anomalies with the potential of being used to commit illegal financial transactions. It is shown that fraudsters have a concentrated history of fraudulent operations in transfer and cash-out operations and this is commonly concentrated around small to mid-value cycles that replicate real world methods of hiding larger amounts of money by making smaller and less noticeable transactions. Time-related and network analyses further indicate that fraudulent activities also create networks and chains that are reminiscent of terrorist funding. In addition to the technical discoveries, the study also considers the ethical issues of privacy, transparency, and equity in implementing AI in the financial systems. In general, the study indicates that AI-based data analysis can profoundly improve ho…

The Digital Shield: An Analysis of AI's Role in Protecting US Financial Infrastructure from Cyberattack
type: item
description: The complexity of cyberattacks is a consistent challenge to the stability and credibility of financial institutions in the United States. Increasing vulnerability of financial systems to cyber-based criminal activities, including fraud, data breach and identity theft, has been observed as a result of the rapid pace of digital transformation. This study examines how data analytics facilitated by Artificial Intelligence (AI) can improve cybersecurity conditions in financial institutions by forecasting, identifying, and addressing possible threats on a real-time basis. I used two data sets to complete this research: the IEEE-CIS Fraud Detection dataset, which includes anonymized transactional information about the U.S. financial systems, and the Cyber Security Indexes dataset, which gives the world information about cybersecurity preparedness and the exposure. To train and test AI models of Random Forest, XGBoost, and Neural Networks, the IEEE-CIS dataset was used to find out the fraudulent transactions and test their accuracy of detection. Conversely, the dataset of Cyber Security Indexes was processed to compare the cybersecurity preparedness of the United States to the situation in other nations and investigate the relationships between cyber exposure, country preparedness, and digital development. The combined analysis reveals that AI-based models can be useful to identify fraudulent activities with high precision and recall and minimize financial loss and operational risks. The evidence shows that countries that have a better framework of cybersecurity governance and higher levels of Global Cybersecurity Index (GCI) experience less financial cybercrime exposure. This paper has reached the conclusion that AI-based analytics coupled with a strong cybersecurity framework forms a holistic protection scheme in the financial sector, which is more resilient, compliant with regulations, and trusted by the population. These findings highlight the potential of AI to transfo…

Research on the Application of Machine Learning in Fault Diagnosis Technology
type: item
description: Modern industrial equipment is increasingly characterized by large scale, high complexity, and continuous operation. Traditional fault diagnosis methods exhibit significant limitations when dealing with massive volumes of data and various nonlinear relationships. Machine learning, which is capable of autonomously discovering patterns and identifying structures from data, provides a novel pathway for fault diagnosis. This paper systematically reviews the fundamental theories, commonly used algorithms, and practical application scenarios of machine learning in fault diagnosis, with particular attention to the applications of supervised learning and unsupervised learning in the fields of machinery, electric power, and transportation. It then discusses the current challenges, including poor data quality, limited model interpretability, and insufficient fault samples. Finally, future development directions are explored from the perspectives of explainable artificial intelligence, generative models, edge computing, and physics-informed data fusion. Overall, machine learning is driving fault diagnosis from a “repair-after-failure” paradigm toward “predictive maintenance.” However, for robust deployment in industrial environments, further efforts are still required in algorithm transparency, data efficiency, and cross-domain adaptability.

Privacy-Preserving Chargeback Intelligence for Tokenized Payment Systems
type: item
description: Chargeback handling in modern payment systems remains heavily dependent on post-transaction workflows that expose more payment data than necessary and often rely on PAN-linked retrieval paths. This paper presents a privacy-aware post-transaction architecture for tokenized payment sys- tems that combines chargeback intelligence, selective evidence disclosure, and audit-oriented work- flow design. Beyond system integration, the paper introduces a formal role-based selective-disclosure policy model, a token-lineage risk formulation for dispute scoring, and an evidence-quality framework that separates completeness, relevance, and verifiability. The proposed framework contains a token- aware chargeback intelligence layer, a privacy-preserving evidence layer, and a compliance-aware audit layer to support PAN-less dispute handling wherever feasible. Public transaction datasets are used as the empirical basis, with token-related post-transaction structures constructed through controlled augmentation because the source datasets do not natively contain tokenized dispute workflows. The evaluation uses PaySim as the base transaction backbone, the ULB/Worldline credit-card fraud benchmark for fraud-context support, and a chargeback-labeled dataset for dis- pute modeling. In the primary chargeback prediction experiment, the token-aware model achieved an AUC of 0.9317 and an F1-score of 0.6710, outperforming both a static rule baseline and a ba- sic machine-learning baseline. Additional analysis includes ablation testing, sensitivity analysis, repeated-trial workflow evaluation, and failure-oriented threat scenarios. The proposed workflow reduced the weighted privacy-exposure score by 79.1% relative to a PAN-oriented baseline while improving evidence quality at the cost of higher operational overhead. These findings suggest that token-aware post-transaction intelligence can improve dispute prediction and reduce sensitive-data exposure simultaneously. The paper contributes a practi…

Machine Learning-Based Hospital Readmission Prediction and Risk Analysis in the United States Healthcare System
type: item
description: Hospital readmission is a significant challenge in the United States healthcare system, leading to increased healthcare costs, hospital overcrowding, and reduced quality of patient care. Early prediction of hospital readmission risk can help healthcare providers identify high-risk patients and take preventive measures before discharge. This study presents an explainable machine learning-based hospital readmission prediction framework using patient demographic and clinical data from the United States healthcare system. The dataset includes important patient information such as age, length of hospital stays, previous admission history, comorbidities, insurance status, disease type, diabetes, heart disease, and follow-up visit status. Several machine learning algorithms, including Logistic Regression, Random Forest, Extreme Gradient Boosting (XGBoost), and Artificial Neural Network, were used to predict hospital readmission risk. The performance of the models was evaluated using accuracy, precision, recall, F1-score, and Receiver Operating Characteristic (ROC) curve. Among all models, XGBoost achieved the highest prediction performance compared to other machine learning models. Feature importance analysis showed that length of hospital stay, comorbidities, insurance status, previous admission history, and follow-up visit were the most significant factors influencing hospital readmission in the United States. In addition to the machine learning prediction model, this study proposes an IoT-based post-discharge patient monitoring system to reduce hospital readmission risk through continuous patient health monitoring and early medical intervention. The proposed system can help healthcare providers monitor patients remotely, identify high-risk patients in real time, and take preventive actions to reduce hospital readmission rates. This research contributes to the development of intelligent healthcare prediction systems and demonstrates how machine learning and IoT technolog…

Human-in-the-Loop Reinforcement Learning for Next-Generation Adaptive Interfaces
type: item
description: Most adaptive interface research lands in one of two places: fully automated systems that ignore the user's evolving intent, or static personalization that freezes in place after an initial configuration pass. Neither age well. This paper takes a different approach. We propose a Human-in-the-Loop Reinforcement Learning (HITL-RL) framework where the interface policy continues to evolve through a combination of behavioral observation and direct user input, without requiring the user to become an unwitting trainer. The core architecture pairs a reinforcement learning agent with a hybrid feedback channel that fuses implicit signals (click patterns, dwell time, abandonment) with explicit corrections users make. Drawing on reward modeling techniques from large-scale language model alignment work, we adapt the preference learning paradigm to interface-level decisions: layout, component prioritization, and interaction sequencing. Policy updates run continuously but remain interpretable, giving users meaningful visibility into why the interface changed. We evaluate the framework against static personalization baselines and fully automated RL approaches across three interface contexts. The results show measurably faster convergence to preferred layouts, higher rated usability scores, and lower correction frequency over time, which suggests the system is learning rather than just adapting noisily. Beyond the metrics, HITL-RL shifts the design philosophy: the interface is not a product delivered to the user, it is a policy negotiated with them.

Learning Agility, Institutional Support, and AI Governance as Predictors of Artificial Intelligence Tensions among Postgraduate Students in Uganda
type: item
description: The integration of AI into higher education has sparked debates among scholars, especially regarding ethics, accountability, legitimacy, and academic practices. In this context, this study examined whether learning agility, institutional support, and AI governance could predict the level of tension among postgraduate students in Uganda's public higher education institutions. Using a quantitative design and a cross-sectional survey, the researcher collected substantial data from 88 postgraduate students; however, only 71 responses were analyzed. The data were examined through descriptive statistics, Pearson correlation, and multiple linear regression. The overall results indicate that respondents exhibited a relatively high level of learning agility, moderate institutional support, moderate levels of AI-related tension, and a low perception of AI governance. The correlation analysis showed that learning agility, institutional support, and AI governance were all positively correlated with AI tension. The only variable that emerged as a statistically significant predictor in the regression analysis was AI governance. In contrast, learning agility and institutional support did not have independent significant effects. These findings suggest that postgraduate students’ perceptions of AI tension are more influenced by the socio-institutional environment than by their adaptive abilities. The study concludes that AI tension in higher education mainly reflects socio-institutional factors, requiring clear, practical, and trust-building measures as prerequisites for responsible AI integration. The data provide context-specific evidence from Uganda and contribute to the existing literature on AI in higher education by showing that governance is not merely a background condition but a key factor shaping students' perceptions of their AI experiences in academia.

Risk-Aware Rework Prevention in Personalized Hearing Aid Manufacturing
type: item
description: The manufacturing of custom hearing aids is done under a degree of variability that is hard to manage using standard production logic since each order is an expression of an individual anatomy, fitting needs, and design-specific decisions about the product. This means that it is frequently found out too late, after line time, operator effort and material have been used, resulting in avoidable delay and unnecessary burden on manufacturing resources. This paper builds a risk aware execution model to detect probable rework-prone orders earlier in the production process and to take action on the risk before downstream cost is incurred. The framework integrates order-context capture, risk profiling, rework-risk prediction, intervention selection, execution rout- ing and feedback-based updating in a closed operational loop. Actions that are triggered by the system may include parameter checking, expert checking, alternate routing, or controlled release, depending on the estimated risk level before the order is sent to more costly downstream stages. The main point is that prediction can only be valuable when it alters the way the order is man- aged. In that perspective, rework-risk estimation is included in manufacturing control, as opposed to an independent analytical output. The anticipated advantage is reduced rework load, enhanced turnaround performance, increased attention to specialists, minimized material waste, and more stable production flow in the personalized production of healthcare devices.

PAN-Less Refunds and Privacy-Preserving Chargeback Evidence for Tokenized Payment Gateways
type: item
description: Tokenization reduces routine merchant exposure to primary account numbers, yet refund handling and chargeback evidence preparation often remain dependent on PAN-linked or PAN-adjacent re- trieval paths. This paper presents an exploratory systems-design and workflow-evaluation study of a token-linked post-transaction architecture for PAN-less refunds and privacy-preserving charge- back evidence generation. The proposed design links payment, refund, and dispute records through explicit token lineage, confines PAN-linked authority to a token-service boundary, and applies role- based selective disclosure during evidence release. The empirical study uses uploaded public datasets and documented lifecycle augmentation because the source data do not natively contain tokenized refund and dispute chains. Validation was strengthened through 30 repeated trials on random sub- sets of 15,000 PaySim-derived base events per run, with chargeback-oriented calibration from the uploaded df.csv file and anomaly-context support from the uploaded fraud benchmarks. Across the repeated trials, the proposed workflow reduced the weighted privacy-exposure score from 1.48 to 0.31, improved the evidence-quality score from 0.5946 to 0.7344, and increased the operational- overhead index from 1.00 to 1.67. Mean local refund-processing time increased from 0.00394 ms per case to 0.00448 ms per case, while mean local evidence-assembly time increased from 0.01882 ms per case to 0.07069 ms per case. These timings reflect only local in-memory workflow steps and should not be interpreted as production gateway or payment-network latency. Sensitivity analy- sis shows that the reduction of privacy is between 65.6% and 86.0% under alternative weighting schemes, and the evidence-quality advantage is positive under all weighting scenarios tested. The paper therefore makes a bounded contribution: explicit architecture, reproducible augmentation rules, custom-metric definitions with sensitivity checks, and repeat…

Transforming Undergraduate Education Through Modern Pedagogical Innovations
type: item
description: The undergraduate education is experiencing a paradigm change whereby common teaching methodologies are finding it difficult to cope with the changing needs of a society that is dynamic and knowledge-oriented society. Innovations in modern pedagogy are characterized by focus on active learning, experiential learning, and use of technology in order to impart in students the skills of critical thinking, problem-solving, and collaboration aspect of life that are necessary to succeed in the workplace. The paper examines how education has been developed and what pedagogical needs are emerging, which can be discussed as the shift to the traditional lecture-based learning and the use of technology-focused, student-oriented learning methods. New techniques, such as project-based learning, flipped classes, collaborative techniques, and reflective practices are discussed in their contribution to the development of technical skills, analytical intelligence, and applied knowledge. A case study conducted at the Federal Institute of Amazonas shows that the combination of experiential learning and project-based exercises had a considerable impact on student motivation and performance as well as the practical acquisition of skills. The results indicate that the gap between theory and practice can be reduced by incorporating contemporary pedagogical approaches and equipping graduates with skills to address complex professional environments and facilitate lifelong learning and flexibility in an ever-evolving environment.

An AI-Driven Classification System for Early Detection of Customer Churn in E-Commerce Platforms
type: item
description: Customer churn is a key issue for e-commerce organizations since it lowers revenue and hampers long-term growth. E-commerce companies may reduce expensive customer attrition and implement proactive retention measures by predicting client churn. This study proposes an AI-driven classification system for early customer churn detection using the List online retail dataset. The proposed CNN has a higher ability in capturing complex and nonlinear patterns of customer behavior as opposed to the conventional machine learning methods. The results of the experiment display excellent performance, with 99.62% accuracy, 99.32% precision, 98.66% recall, and 98.78% F1-score and with the AUC of 0.9893. The findings demonstrate that the model is robust, has generalization and small misclassification with respect to the baseline models like Random Forest, Logistic Regression, AdaBoost and ANN-MLP. In addition to predictive strength, the paper highlights an importance of DL in extracting latent features representations and provides actionable information on customer retention strategies. The results determine CNNs as a strong and justified solution in detecting churn that provides academic value and practical applicability to the e-commerce industry.
