The phenomenon of atmospheric haze arises due to the scattering of light by minute particles suspended in the atmosphere. This optical effect gives rise to visual degradation in images and videos. The degradation is primarily influenced by two key factors: atmospheric attenuation and scattered light. Scattered light causes an image to be veiled in a whitish veil, while attenuation diminishes the image inherent contrast. Efforts to enhance image and video quality necessitate the development of dehazing techniques capable of mitigating the adverse impact of haze. This scholarly endeavor presents a comprehensive survey of recent advancements in the domain of dehazing techniques, encompassing both conventional methodologies and those founded on machine learning principles. Traditional dehazing techniques leverage a haze model to deduce a dehazed rendition of an image or frame. In contrast, learning-based techniques employ sophisticated mechanisms such as Convolutional Neural Networks (CNNs) and different deep Generative Adversarial Networks (GANs) to create models that can discern dehazed representations by learning intricate parameters like transmission maps, atmospheric light conditions, or their combined effects. Furthermore, some learning-based approaches facilitate the direct generation of dehazed outputs from hazy inputs by assimilating the non-linear mapping between the two. This review study delves into a comprehensive examination of datasets utilized within learning-based dehazing methodologies, elucidating their characteristics and relevance. Furthermore, a systematic exposition of the merits and demerits inherent in distinct dehazing techniques is presented. The discourse culminates in the synthesis of the primary quandaries and challenges confronted by prevailing dehazing techniques. The assessment of dehazed image and frame quality is facilitated through the application of rigorous evaluation metrics, a discussion of which is incorporated. To provide empiri

—This paper presents an advanced optical sensor based on surface plasmon resonance (SPR) designed to detect hyperuricemia, characterized by elevated uric acid (UA) levels. The sensor features a stacked nanocomposite comprising gold-graphene quantum dots (GQD) biofunctionalized with uricase enzyme, ensuring high sensitivity and selectivity for UA detection over other potentially competing interferents like ascorbic acid, glucose, D-cystine, urea, and creatinine commonly found in biological samples. The developed sensor achieves an impressive sensitivity of 0.093◦/(mg/dL) for UA at 12 mg/dL, significantly higher than the recorded sensitivity of 0.015◦/(mg/dL) for all other potential interferents at the same concentration. This highlights the sensor’s exceptional precision in discerning UA. Moreover, the sensor demonstrates notable selectivity for UA even at low concentrations, registering a resonance angle shift of 0.371◦ at 0.5 mg/dL, compared to a lower angle shift of 0.185◦ for other interferents at higher concentrations of 12 mg/dL. These findings emphasize the sensor’s accuracy and rapid response in distinguishing UA, positioning it as a promising tool for early diagnosis and management of hyperuricemia in clinical settings, addressing a critical need for reliable and efficient UA detection. ©2024 IEEE.

This paper proposes a 1D residual convolutional neural network (CNN) for classifying arrhythmias based on electrocardiogram (ECG) signals. The additional residual blocks and skip connections effectively alleviate the gradient problem in deep neural networks by providing a direct path for gradient propagation and enhancing the feature information propagation. In addition, the SMOTE-Tomek technique was demonstrated in this work to mitigate the effects of class imbalance caused by a large amount of data during model training and effectively increase the SNR of the training set. The robustness of the model is increased by adding the cosine annealing technique and L 2 regularization. The proposed model was evaluated with various performance metrics, resulting in an accuracy of 9 8. 7 4 %, sensitivity of 9 8. 3 5 %, specificity of 9 1. 8 6 %, precision of 9 7. 9 5 %, and F1 score of 9 8. 1 4 % on the MIT-BIH Arrhythmia Database. The result shows better performance for classifying previously unseen data for the proposed approach as compared to the state-of-the-art works. © 2025 IEEE.
