Security Challenges in Cross-Chain Asset Transfer Systems
The rapid growth of blockchain technologies and decentralized finance has significantly increased the demand for secure interoperability solutions between independent blockchain networks. Cross-chain asset transfer systems, commonly known as blockchain bridges, enable the movement of digital assets and data across multiple blockchain ecosystems, improving scalability, liquidity distribution, and usability of decentralized applications. However, the increasing adoption of cross-chain infrastructures has also introduced substantial security risks. In recent years, bridge-related exploits have resulted in financial losses exceeding billions of US dollars, making interoperability systems one of the most vulnerable components of decentralized ecosystems. This paper analyzes the primary security challenges associated with cross-chain asset transfer systems and examines the architectural characteristics of modern blockchain bridge solutions. The study reviews major bridge architectures, including lock-and-mint bridges, burn-and-release bridges, liquidity pool bridges, validator-based bridges, and light-client bridges. In addition, the paper investigates common attack vectors such as smart contract vulnerabilities, replay attacks, validator compromise, oracle manipulation, multisignature weaknesses, consensus desynchronization, and liquidity draining attacks. The research further evaluates several major bridge exploits, including the Ronin Bridge, Wormhole, and Nomad incidents, in order to identify recurring security weaknesses and operational failures. The paper also discusses mitigation strategies such as decentralized validation mechanisms, threshold signature schemes, formal verification, anomaly detection systems, transaction monitoring, and rate-limiting approaches. Finally, the study explores future research directions related to zero-knowledge interoperability systems, AI-based fraud detection, trust-minimized bridge architectures, and quantum-resistant cryptographic mechanisms. The findings demonstrate that achieving secure and scalable interoperability remains one of the central challenges in modern blockchain infrastructure development.

Hybrid Machine Learning and Deep Learning Approaches for Network Traffic Anomaly Detection: A Literature Review
Network traffic produces large volumes of data every second, and traditional security tools often struggle to detect new or unknown attacks hidden within this traffic. Anomaly-based intrusion detection systems address this problem by learning normal network behavior and identifying suspicious deviations. This literature review examines recent studies that use machine learning, deep learning, and hybrid machine learning-deep learning approaches for network traffic anomaly detection. The review focuses on feature selection, model complexity, dataset use, evaluation metrics, and the practical challenges that still limit real-world deployment. The reviewed studies show that traditional machine learning models can remain efficient when supported by careful feature selection, while deep learning models are useful for learning more complex spatial and temporal traffic patterns. Hybrid approaches often report stronger performance because they combine the speed and simplicity of machine learning with the representational power of deep learning. However, the literature also shows continuing weaknesses, including reliance on static benchmark datasets, class imbalance, computational cost, limited explainability, and uncertainty about performance in live networks. The review concludes that hybrid approaches are promising, but their future value depends on making them lighter, more explainable, and more reliable outside controlled experimental settings.

A Review of Explainable Federated Learning Frameworks for Chest X-ray Diagnosis under Heterogeneous Hospital Data
The application of deep learning in chest X-ray diagnosis has demonstrated promising results in detecting multiple thoracic diseases. However, traditional centralized approaches face significant challenges, including limited generalization across hospitals with heterogeneous patient populations and imaging protocols, compounded by strict privacy regulations such as the Health Insurance Portability and Accountability Act (HIPAA) and the General Data Protection Regulation (GDPR) that prevent data sharing between institutions. Although centralized deep learning approaches perform well and achieve high local accuracy on their predictions, they are often “black boxes,” which limits clinical trust and interpretability. This review examines existing explainable federated learning frameworks for chest X-ray diagnosis under heterogeneous data conditions. Current approaches enable decentralized training across non-independent and identically distributed (non-IID) hospital environments, utilizing robust aggregation strategies such as Federated Averaging (FedAvg) and Federated Proximal (FedProx) to address label, quantity, and feature skew. To establish clinical trust, explainable Artificial Intelligence (XAI) techniques, such as Gradient weighted Class Activation Mapping (Grad CAM) and SHapley Additive exPlanations (SHAP), have been incorporated to generate interpretable visual explanations. The reviewed frameworks are evaluated on classification performance, robustness under heterogeneity, and stability of generated explanations. However, this review reveals significant gaps: the types of heterogeneity are addressed in isolation, XAI evaluation remains largely qualitative, and explanation stability under non-IID conditions lacks rigorous validation. These findings collectively highlight the need for federated frameworks that unify heterogeneity handling across all its forms simultaneously rather than addressing each in isolation, quantitative XAI assessment, and validation of explanation consistency across diverse hospital environments to enable trustworthy and interpretable clinical deployment.

Edge-Optimized Pre-Trained Deep Learning Models for Real-Time Detection of Red Palm Weevil and Date Palm Diseases: A Review
Date palm (Phoenix dactylifera L.) constitutes one of the most economically and culturally significant crops across arid and semi-arid regions, yet its productivity faces existential threats from the Red Palm Weevil (Rhynchophorus ferrugineus, RPW) and a spectrum of fungal and bacterial diseases. While deep learning has demonstrated remarkable classification accuracies exceeding 97% in controlled laboratory environments, the transition from academic prototypes to deployable, real-time agricultural solutions remains critically underdeveloped. This comprehensive review systematically examines recent studies, synthesizing the current landscape of deep learning applications for RPW detection and date palm disease classification. Our analysis reveals a persistent disconnect between architectural sophistication and practical deployability. Furthermore, the literature exhibits a pronounced fragmentation between pest detection and disease classification, with few studies addressing the integrated palm health ecosystem. This review identifies critical research dimensions where the current state-of-the-art falls short. By mapping these interconnected gaps across the evaluated literature, this review establishes a structured roadmap for developing lightweight, accurate, and interpretable AI systems that bridge the gap between theoretical accuracy and operational feasibility in precision agriculture.

Robust Deep Residual Networks with Pixel-Level Pre-Processing for Decentralized Traffic Sign Recognition
While traffic sign recognition systems play a vital role in road safety and autonomous driving, traditional architectures often suffer severe accuracy degradation under adverse environmental conditions such as low light, fog, and heavy shadows. Although federated deep learning and convolutional neural networks (CNNs) have successfully advanced decentralized edge intelligence, standard RGB image processing remains a critical bottleneck for vehicles encountering environmental noise. To address this, we propose a lightweight, decentralized ResNet-34 architecture designed for embedded applications, enhanced by a robust multi-space pixel-level pre-processing pipeline. By incorporating localized edge contrast enhancement and chromatic variance stabilization (utilizing HSV and Ohta spaces), the proposed system isolates critical luminance and structural features prior to decentralized feature extraction. The framework was trained and evaluated on the German Traffic Sign Recognition Benchmark (GTSRB) and the Belgian Traffic Sign Data Set (BTSD). The results demonstrate that coupling dynamic image pre-processing with federated residual learning yields a highly efficient, accurate, and environmentally resilient system suitable for real-time edge deployment.
