Due to the lack of security mechanisms in controller area networks, they have become increasingly susceptible to attacks. While the physical-layer authentication can detect masquerade attacks by exploiting the uniqueness of the ECU features, such as signal voltage, to formulate the fingerprints, it suffers from low accuracy in large-scale CANs. In this paper, the study proposes an open-set physical-layer authentication scheme, which applies deep metric learning to improve the authentication accuracy for CANs with a large number of ECUs against both masquerade attacks and ranged attacks. Our scheme improves the triplet loss function to learn the latent feature representation of the known ECU signals. Experimental results verify the efficacy of our proposed scheme. The SigTLNet algorithm exhibits optimal recognition performance for both masquerade and remote attacks. It achieves average recognition rates of 99.59% for known nodes and 100% for unknown nodes during masquerade attacks, while for remote attacks, the rates are 99.30% and 100%, respectively.

To tackle the aforementioned deficiency, we introduce a novel diverse multi-scale feature absorption network (DMFA-Net) to guide lightweight detectors work efficiently in foggy weather conditions. Our approach achieves its objective through the close collaboration of three subnetworks: a detection enhancement subnetwork, a depth mining subnetwork, and a lightweight detection subnetwork. The lightweight detection subnetwork achieves a significant accuracy improvement by absorbing and learning a range of useful features from both the detection enhancement and depth mining subnetworks through diverse multi-scale feature absorption loss. Extensive experiments demonstrate that our DMFA-Net effectively boosts baseline lightweight detectors in accurately localizing and classifying objects, without adding any computational cost.

In this effort, existing studies have presented interesting results by using physiological signals. However, most works focus primarily on single physiological signal like electroencephalography (EEG). To address this gap, we propose an innovative cross-modal fusion method (CM-FusionNet) and conduct a multi-modal study using EEG and electrooculogram (EOG) for mental fatigue detection. Specifically, a variance channel attention (VCA) module is introduced to adaptively learn the optimal weights for each channel. Then, a Transformer fusion module is applied to extract and integrate the global features of EEG and EOG. Finally, we classify mental fatigue using the fused features. With this method, we conduct independent and cross-subject experiments on the public SEED-VIG dataset. The results of multi-modal experiment show an average accuracy of 84.62% and F1-score of 85.25%, an increase by 1.48% in accuracy 2.46% and in F1-score compared to the EOG-only experiment, and increase by 2.88% and 3.92% compared to the EEG-only experiment, respectively.

Firstly, in the coding stage, the hybrid convolution attention module is used to enhance the feature extraction capability of the model. The design of adaptive connection helps the model to better capture the context information of the source image, and can adaptively calculate the weight of the feature map, and superimpose the feature map according to the weight. Secondly, deformable convolution module is used in decoding phase to enhance the modeling ability of complex edge details in the focused region and improve the feature reconstruction ability of the network.

The study evaluates the impacts of power exchange by consumers on the profits and costs of stakeholders while minimizing operational costs, maximizing power exchange profits, and ensuring residential comfort levels. Additionally, optimal scheduling and reconfiguration of the active distribution system have been proposed. In the first level, the optimization process focuses on the residential demand response aggregators and electric vehicle parking lots, incorporating Cournot-based competition among residential aggregators and prioritizing carbon emissions reduction and fuel savings. In the second level, self-scheduling of multi-carrier energy hubs is performed to determine profits and costs. In the third level, the proposed procedure considers the contribution of lower-level agents that can be utilized for scheduling and reconfiguring the active distribution system.

Because sensor nodes are expensive to deploy in underwater environments and have limited energy capacities, energy optimization is a significant and practical issue, particularly for extending network lifetime. Today, various energy-efficient routing strategies have been suggested by combining opportunistic routing (OR) and reinforcement learning (RL). However, this subject deals still with different challenges. This paper introduces a Q-learning-based hierarchical routing protocol (QHRP) in UASNs. This approach builds a Q-learning-based routing tree, which contains a state set filtered by a two-step filtering process. It effectively increases the convergence speed of the Q-learning algorithm and lowers delay due to the tree construction process. In QHRP, the reward function considers network conditions and is obtained based on four metrics, namely remaining energy, strategic depth, the size of the state set, and successful transmission probability. Moreover, QHRP solves the void area problem in the routing tree by redefining the set of states and reward function. To evaluate QHRP compared to the three routing methods, namely RLOR, EE-DBR, and MURAO, various experiments are performed in terms of packet delivery rate (PDR), end-to-end delay (EED), data integrity, consumed energy, and the number of hops in the forwarding routes.
