Histopathological analysis, particularly of nuclear morphology, is critical for identifying malignancies. Accurate nuclei segmentation plays a pivotal role in this process, as it enables detailed assessment of nuclear size, shape, and distribution patterns. Traditional segmentation methods, however, often fail to capture fine details, lack broader context, and struggle with overlapping nuclei of varying sizes and shapes, especially when relying on single-scale approaches. To address these challenges, we propose a multi-scale context-based encoder-decoder model named M3-Net (Multi-Scale, Multi-Level, Multi-Stream Network) that integrates both global and local tissue features. Evaluations demonstrate that M3-Net effectively segments overlapping nuclei and diverse structures, providing a robust solution for automated nuclei segmentation in breast cancer pathology.

The rapid advancements in quantum computing present significant challenges to traditional cryptographic techniques, posing risks to the security of e-commerce transactions. Existing systems are vulnerable to quantumenabled cyberattacks, especially as classical encryption methods, such as RSA and ECC, become obsolete in the face of quantum algorithms. In response, the research proposes an innovative quantum-secure e-commerce fraud detection framework that integrates Graph Neural Networks (GNNs) with Quantum Key Distribution (BB84 QKD), Quantum-Proof-of-Work (QPoW), blockchain technology, and post-quantum cryptographic techniques, including BLAKE3 encryption. The key challenge addressed in the work is ensuring transaction security and fraud detection in a quantum-enabled environment, where classical cryptographic systems are no longer sufficient. Traditional fraud detection mechanisms also struggle to detect subtle anomalies in complex, quantumsecured transaction networks. This approach overcomes these issues by leveraging deep learning-based anomaly detection through GNNs, which model blockchain transactions as graphs to capture intricate relationships between entities. The combination of BB84 QKD ensures secure key distribution, while QPoW offers a resilient consensus mechanism, and BLAKE3 encryption provides fast and secure hashing. The framework aims to offer a robust, scalable solution for ecommerce platforms, financial institutions, and digital identity systems by combining quantum-secure encryption with advanced machine learning for fraud detection. By addressing the growing threat of quantum computing, the methodology provides enhanced security for sensitive transactions, ensuring long-term protection against future quantum-enabled attacks.

One of the essential nutrients Vitamin C is abundantly found among citrus fruits and holds a lot of significance in supporting public health and economic benefit to the country and the stakeholders in the Citrus industry. Citrus fruit production is greatly affected as they are susceptible to various range of diseases. Thus, protecting them from diseases has a direct impact on the growth and yield of Citrus production. Thus, providing support in the form of early disease detection and prediction can enhance productivity to a greater extent. This frames the motivation behind this work and a deep learning-based classifier is suggested to enhance the accuracy of the Citrus plant disease prediction. Though numerous deep learning-based classifier exists in literature, their significant limitation is the need for high computational resources. This makes them unsuitable to deploy on low-end devices. To address this issue, a pipeline that possesses the key processes like classification, augmentation, transfer learning, and image enhancement as a comprehensive methodology to improve the predictive performance and easy deployment features. The approach mainly focuses on solving the data imbalance issues that have detrimental effects on classifier training. To solve this, we used SCLAHE (Spatially Adaptive Histogram Equalization) for image enhancement, which improves the visibility of critical features in citrus leaf images. Additionally, we incorporate RL-GAN (Reinforcement Learning Generative Adversarial Network) for real-time data augmentation, generating synthetic images that enhance the training dataset and help to address the imbalance. The effectiveness of our method has been validated through extensive evaluation using two prominent datasets: Citrus Leaves and CCL-20. The results reveal an impressive accuracy rate of 99.42%, along with six parameter counts and ten FLOP (floating-point operations) counts. This high level of accuracy demonstrates the potential of our deep

This paper investigates the improvement of Vehicle-to-Vehicle (V2V) communications in the Internet of Drones (IoD) scenario for the reduction of the Peak-to-Average Power Ratio (PAPR) problem in Orthogonal Frequency Division Multiplexing (OFDM) systems. Motivated by the recent research on machine learning and deep neural network, this study will attempt to optimize Quality of Service (QoS) by means of a multiprocessing approach based on Daubechies wavelets. The proposed scheme integrates high-performance PAPR reduction schemes, such as µ-law companding, hybrid precoding-companding, and neural network-based adaptive algorithms. Deep reinforcement learning-driven approach in clipping and filtering is further proposed, which can offer real-time adaptation for the high-demanding communications. Results show a considerable gain in PAPR, over 60% PAPR reduction under high SNR conditions. These findings show that IoD can sustain stable V2V connections in urban use cases, thereby providing a scalable solution for 5G and beyond networks.
