The Internet of Medical Things (IoMT) brings advanced patient monitoring and predictive analytics to healthcare but also raises cybersecurity and data privacy issues. This paper introduces a deep-learning model for IoMT intrusion detection, utilizing the WUSTL EHMS 2020 dataset, which focuses on cyber threats like man-in-the-middle attacks and data injection. Our sequential model, trained with TensorFlow, surpasses traditional predictive accuracy and efficiency methods. It achieves 99% accuracy with reduced loss and excels in precision, recall, F1 Score, and ROC AUC. The model uses 25 key features from 45, preventing overfitting and addressing data leakage in preprocessing. These steps ensure the model's reliability for IoMT cybersecurity, demonstrating its effectiveness in real-world scenarios. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

Among various traffic data modeling and predicting methods, graph learning-based models attract more attention, because of their powerful representation ability for modeling spatial and temporal dependencies with graph neural networks. Despite their promising performance, several key problems have not been well addressed: 1) Sensed data are often noisy in many real transportation scenarios. 2) The spatio-temporal correlations of traffic data are complex and dynamic, especially for long-term modeling and predicting. In such cases, existing methods may not lead to satisfactory prediction results. In this paper, we aim at the above problems by exploring a Spatio-Temporal Heterogeneous Graph Neural network With Multi-View Learning Framework(MVJGL) for traffic prediction. In particular, we first model different types of traffic features and construct multiple graph structures. Then, we design two parallel heterogeneous gated temporal convolution modules to extract long and short-term temporal dependencies from different traffic features, respectively. Moreover, we introduce parallel graph convolutions to cross-characterize the time-varying spatial dependencies of each view. Extensive experiment results on four real traffic datasets show the superior performance grain obtained by the proposed model. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Yet the Internet of Things continues to grow significantly. A cyber-physical system faces a variety of security challenges due to the network connections made by the various kinds of devices and large systems that make up national infrastructures like a smart grid. Here, For the forward flow and the feedback path of a control system, respectively, we suggest two fake data injection attacks. Both are made using a variable parameter that determines the degree of deterioration. On the forward path, a linear forward assault is created together with the least squares approach. The Kalman filter is constructed on the feedback route. According to the numerical analysis, the suggested assaults govern how much the performance of the control system declines. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

WavEnhancer: Unifying Wavelet and Transformer for Image Enhancement

Image enhancement is a widely used technique in digital image processing that aims to improve image aesthetics and visual quality. However, traditional methods of enhancement based on pixel-level or global-level modifications have limited effectiveness. Recently, as learning-based techniques gain popularity, various studies are now focusing on utilizing networks for image enhancement. However, these techniques often fail to optimize image frequency domains. This study addresses this gap by introducing a transformer-based model for improving images in the wavelet domain. The proposed model refines various frequency bands of an image and prioritizes local details and high-level features. Consequently, the proposed technique produces superior enhancement results. The proposed model’s performance was assessed through comprehensive benchmark evaluations, and the results suggest it outperforms the state-of-the-art techniques.
