The structural similarity of point clouds presents challenges in accurately recognizing and segmenting semantic information at the demarcation points of complex scenes or objects. In this study, we propose a multi-scale graph transformer network (MGTN) for 3D point cloud semantic segmentation. First, a multi-scale graph convolution (MSG-Conv) is devised to address the limitations faced by existing methods when extracting local and global features of point cloud data with varying densities simultaneously. Subsequently, we employ a graph-transformer (G-T) module to enhance edge details and spatial position information in the point cloud, thereby improving recognition accuracy for small objects and confusing elements such as columns and beams. Extensive testing on ShapeNet parts and S3DIS datasets was conducted to demonstrate the effectiveness of MGTN. Compared to the baseline network DGCNN, our proposed MGTN achieves substantial performance improvements, as evidenced by notable increases in mIoU of 1.5% and 18.5% on the ShapeNet parts and S3DIS datasets respectively. Additionally, MGTN outperforms the recent CFSA- Net by 2.3% and 3.4% on OA and mIoU respectively.

Boolean functions used in symmetric-key encryption should have high higher-order nonlinearity to resist several known attacks, such as algebraic attack and low-degree approximation. The higher-order nonlinearity also plays an important role in coding theory and theoretical computer science. It is well-known that bent functions have the highest nonlinearity in even number of variables and thus they possess the best resistance against fast correlation attack and best affine approximation. However, there is limited knowledge regarding the higher-order nonlinearity of bent functionsbecause computing the higher-order nonlinearity, or even providing tight lower bounds, is a hard task. In 1974, Dillon proposed two well-known classes of bent functions based on partial spread (in brief, $\mathcal{PS}$), called $\mathcal{PS}^-$ and $\mathcal{PS}^+$, respectively. He also exhibited a subclass of $\mathcal{PS}^-$, known as partial spread affine plane ($\mathcal{PS}_{ap}$ for short). In this paper, we provide a lower bound on the third-order nonlinearity of the simplest $\mathcal{PS}_{ap}$ bent functions in $n$ variables, where $n\ge 6$ is even, by calculating nonlinearities of all second-order derivatives of this kind of bent functions. Compared to the two known lower bounds on the third-order nonlinearity given by Carlet and Tang et al. respectively, our lower bound is much better than these two ones. © 2023, The Authors.

Using optical fiber links to transmit time information is widely regarded as an accurate and secure time synchronization scheme. However, the accuracy of the round-trip time synchronization system can be manipulated arbitrarily by attack schemes. In this paper, a controllable asymmetric attack scheme against round-trip time synchronization system is proposed and experimentally demonstrated. By adjusting the asymmetry of the link, the time synchronization accuracy can be controlled down from 23 ps to 0.91 ns, 2.13 ns and 5.20 ns. Our work reveals system vulnerability caused by asymmetry, and points out that current systems can be attacked unwittingly by adversaries.

An important issue in cancer genomics is the identification of driver genes. It is significant for the discovery of key biomarkers and the development of effective personalized therapies. In this paper, a computated method PGScore is proposed. It scores genes at multilayer and integrates the scores to identify cancer driver genes based on Pareto Optimality Consensus(POC) strategy. PGScore uses random walks to reevaluate gene mutations, and integrates differential expression of mRNA and miRNA in normal and cancer samples. It measures the centrality of the gene in the network according to the weight of its direct and indirect neighbors, and finally integrates the above layers to get the final priority of the genes. We compare PGScore with state-of-the-art cancer driver genes prioritization methods on two real cancer datasets. The results show that PGScore can obtain better performance in identification accuracy and the partial area under the ROC(pAUC) curve on multiple reference databases. © 2022 IEEE.

This paper considers a multi-antenna jamming to facilitate covert communications with multiple wardens. Specif-ically, the jammer generates artificial noise (AN) with random power to deliberately create interference to prevent a communication being detected by an adversarial warden (Willie), where Warden's location is modeled as a uniform binomial point process (BPP). The detection performance for each warden is analyzed under line-of-sight (LoS) channels i.e., the expressions for the false alarm $(P_{FA})$ and miss detection $(P_{MD})$ probabilities are analytically derived. Then, the communication performance of the covert communication in terms of the channel capacity is optimized following a stochastic spatial geometry framework. Nu-merical results show that the average detection error probability $(\mathbf{i.e}.,\ P_{FA}+P_{MD})$ decreases with the number of Willies and also decreases as the the jammer gradually parallel to the receiver's position relative to the transmitter, which leads to the reduction in the covert throughput.

Phase retrieval seeks to reconstruct a series of image sequences from measurements that only capture their magnitudes. Current approaches either flatten and stack the image sequences, disregarding their multidimensional structural information, or fail to account for errors within the sensing vectors/tensors. To address these two issues simultaneously, we propose a unified framework for the phase retrieval problem, namely tensor total least squares (TTLS). Specifically, we set up a tensor representation for image sequences and the corresponding measurement model, and for the first time employ the advanced tensor ring network to effectively explore the inherent multidimensional structure for more accurate estimation. Moreover, in addition to the additive noise, the multiplicative errors within the sensing tensor can be also well-corrected, leading to a more robust estimation. Experimental results on both simulated data and real videos demonstrate the superiority of the proposed method.

Mitigating Receiver Impact on Radio Frequency Fingerprint Identification via Domain Adaptation

Radio Frequency Fingerprint Identification (RFFI), which exploits non-ideal hardware-induced unique distortion resident in the transmit signals to identify an emitter, is emerging as a means to enhance the security of communication systems. Recently, machine learning has achieved great success in developing state-of-the-art RFFI models. However, few works consider cross-receiver RFFI problems, where the RFFI model is trained and deployed on different receivers. Due to altered receiver characteristics, direct deployment of RFFI model on a new receiver leads to significant performance degradation. To address this issue, we formulate the cross-receiver RFFI as a model adaptation problem, which adapts the trained model to unlabeled signals from a new receiver. We first develop a theoretical generalization error bound for the adaptation model. Motivated by the bound, we propose a novel method to solve the cross-receiver RFFI problem, which includes domain alignment and adaptive pseudo-labeling. The former aims at finding a feature space where both domains exhibit similar distributions, effectively reducing the domain discrepancy. Meanwhile, the latter employs a dynamic pseudo-labeling scheme to implicitly transfer the label information from the labeled receiver to the new receiver. Experimental results indicate that the proposed method can effectively mitigate the receiver impact and improve the cross-receiver RFFI performance. Copyright © 2024, The Authors.
