Efficient gastric tumor detection from endoscopic images using trans-mapped learning models I. Govindharaj, Gnanajeyaraman Rajaram, S. Ravichandran, J. Viswanath, R. Elankavi, J. Raja Biomedical Signal Processing and Control, 2026 Gastric cancer has emerged as a major health concern in recent years, often attributed to improper or unhealthy dietary habits. Early detection remains challenging due to the lack of identifiable symptoms in its initial stages, emphasizing the need for intelligent computational diagnostic methods. This study introduces the Inflate Region-based Tumor Recognition (IRTR) scheme, a novel approach leveraging endoscopy images and trans-mapped learning to detect inflated tumor regions with precision. The proposed scheme employs trans-mapping layers, which are trained to analyze inputs and outputs for identifying high and low-intensity feature regions. By focusing on external boundaries with elevated trans-intensity levels, the scheme effectively identifies regions exhibiting significant differences across the image. These mapped features are then utilized to train a model that repetitively processes high-to-low and low-to-high intensity transitions across input and output layers, enhancing the recognition of inflated tumor regions. Boundary differentiation, a key component of this approach, further refines detection precision from early endoscopic inputs. Evaluation results demonstrate that the IRTR scheme achieves superior performance, with an accuracy improvement of 9.38%, a precision increase of 12.04%, 9.69% in specificity and a mean error reduction of 11.04% for maximum intensity rates. This study underscores the potential of trans-mapped learning in advancing early gastric tumor detection.
Efficient data replication in distributed clouds via quantum entanglement algorithms Prabhu Shankar B, RajKumar N, Jayavadivel Ravi, Viji C, Gobinath J, Govindharaj I, Dinesh Kumar K, Elango Muthusamy Methodsx, 2026 In cloud computing, it remains difficult to make data available in a cloud service such that the data is replicated and maintained consistently across various data centers. Traditional replication systems are sufficient, even though they take too long to process, cause significant data transfers, and face problems with final data consistency. This work presents a new method named Quantum Entanglement-Based Replication Algorithm (QERA), which makes use of quantum entanglement to ensure quick and high-performance synchronization of cloud data across all nodes. In this proposed work, the QERA approach encodes data changes in the primary cloud node onto quantum states and entangled qubit pairs to the related replica nodes. As a result, any change is quickly shown on all replicas without the usual overhead and delay of message broadcasts. It simulates how QERA is designed to decrease latency, promote consistency, and make better use of resources in cloud environments. This paper creates a theoretical framework using IBM Qiskit and Microsoft Quantum Development Kit simulators to compare classical and quantum baseline algorithms. The results show that QERA may greatly enhance the way updates and replications are managed across many cloud systems. It demonstrates how QERA can ensure a very synchronized replication among the remote cloud nodes. Employs a qubit pair entangled to minimize latency and decrease bandwidth expenses as it goes through updates. Combines the idea of quantum teleportation with methods of non-invasive verification made to maintain the integrity of the state without altering the quantum system.
RFF-JSS: A radiomic feature fusion and joint space segmentation framework for automated knee osteoarthritis assessment K. Pugazharasi, Bhuvaneswari Srinivasan, Anandh Nagarajan, I. Govindharaj Journal of Orthopaedic Reports, 2026 Knee osteoarthritis (KOA) is a leading cause of pain and functional disability worldwide. Radiographic severity grading using the Kellgren–Lawrence (KL) scale is widely adopted in clinical practice but remains subjective and susceptible to inter- and intra-observer variability, particularly when distinguishing adjacent grades. This study aims to develop an accurate, interpretable, and anatomically guided framework for automated KOA severity grading from plain knee radiographs. A novel Radiomic Feature Fusion and Joint Space Segmentation (RFF-JSS) framework is proposed for automated KOA severity assessment. The pipeline includes (i) standardized preprocessing of knee radiographs, (ii) anatomically informed tibiofemoral joint space segmentation using a U-Net model, (iii) IBSI-compliant multiscale radiomic feature extraction from medial and lateral compartments, (iv) PCA-based radiomic feature fusion for dimensionality reduction and redundancy suppression, and (v) ordinal-aware KOA severity classification using a Random Forest classifier. The framework was evaluated on 5,820 knee radiographs from two large public cohorts—the Osteoarthritis Initiative (OAI) and the Multicenter Osteoarthritis Study (MOST)—with stratified training, validation, and testing splits. The proposed RFF-JSS framework achieved an accuracy of 94.87%, precision of 95.12%, sensitivity of 94.68%, specificity of 96.10%, F1-score of 94.89%, ROC-AUC of 0.972, and a Quadratic Weighted Kappa (QWK) of 0.947. The method consistently outperformed state-of-the-art approaches, including ResNet-SVM, UNet-Radiomics, Deep-KOA, JSN-Net, RF-RFE, and CNN-KLNet. Ablation studies confirmed the critical contributions of joint space segmentation, compartment-wise analysis, feature standardization, and PCA-based radiomic fusion in improving classification robustness and reducing misclassification between adjacent KL grades. The RFF-JSS framework provides a robust, interpretable, and anatomically grounded solution for automated KOA severity grading from plain radiographs. By synergistically combining joint space segmentation with radiomic feature fusion and ordinal-aware classification, the proposed approach bridges the gap between high predictive performance and clinical interpretability, demonstrating strong potential for large-scale screening and clinical decision support in knee osteoarthritis assessment.
A Blockchain-Enabled Secure Federated Learning Framework for Decentralized AI Systems K. Dinesh Kumar, Yaramati Surya Venkata Chaitanya, Lakkoju Hemanth Sai, I. Govindharaj, B. Prabhu Shankar, S. Edwin Raja Proceedings of 6th International Conference on Expert Clouds and Applications Icoeca 2026, 2026 Federated Learning (FL) allows cooperative model training without the exchange of raw information, which makes it suitable in the privacy-intensive distributed setting. Nonetheless, traditional FL systems are based on centralized aggregation servers, and they are also assumed to participate honestly, which makes them vulnerable to model poisoning and free-rider attacks as well as transparency. This paper suggests TrustChain-FL, which is a federated learning framework based on blockchain with a secure federated learning system, which combines a permissioned blockchain with FL to provide decentralized trust, immutable model update records, and automatic validation via smart contracts. The results in experiments conducted in a simulated federated learning setting show that TrustChain-FL is effective in the scenario of mitigating malicious updates without losing model accuracy and convergence efficiency. The given framework can be applied to decentralized AI applications, including healthcare, smart cities, and industrial IoT. Experimental outcome reaches the best accuracy of up to 92.6% and huge resistance to poisoning attacks when compared to traditional FL Unlike current blockchain-assisted FL systems, TrustChain-FL is decoupled between update validation and aggregation with sparse permissioned consensus.
