Single-layer chiral metasurface for circularly polarized light detection

Authors: Xinjie SUN, Xin HE, Zixin CAI, Xiang HAO

Circular polarizers based on the metasurface suffer from a trade-off between the structural complexity and the polarization extinction ratio (ER). Herein, we present a single-layer chiral metasurface with strong circular dichroism. The structure turns a circularly polarized incident beam into a linearly polarized beam, achieving a high circular polarization ER. The operating wavelength of the proposed metasurface is tunable by changing the geometric parameters. The metasurface’s localized surfac

Q-space-coordinate-guided neural networks for high-fidelity diffusion tensor estimation from minimal diffusion-weighted images

Authors: Maokun Zheng, Zhi Li, Long Zheng, Weidong Wang, Dandan Li, Guomei Wang

Diffusion tensor imaging (DTI) is a widely used imaging technique for mapping living human brain tissue's microstructure and structural connectivity. Recently, deep learning methods have been proposed to rapidly estimate diffusion tensors (DTs) using only a small quantity of diffusion-weighted (DW) images. However, these methods typically use the DW images obtained with fixed q-space sampling schemes as the training data, limiting the application scenarios of such methods. To address this issue,

An attention mechanism-based multi-domain feature fusion approach for active sonar target recognition

Authors: Tongjing Sun, Haoran Xu, Shishuo Ren, Denghui Zhang

Due to the complex and changeable marine environment, the active sonar target recognition problem has always been difficult in the field of underwater acoustics. Deep learning-based fusion recognition technology provides an effective way to solve this problem, but relying on simple concatenation strategies to fuse multi-domain features can cause information redundancy, and it is not easy to effectively mine correlation information between domains. Therefore, this paper proposes an attention mech

Large language model-enhanced probabilistic modeling for effective static analysis alarms

Authors: Xinlong PAN, Jianhua LI, Zhihong ZHOU, Gaolei LI, Xiuzhen CHEN, Jin MA, Jun WU, Quanhai ZHANG

Static analysis presents significant challenges in alarm handling, where probabilistic models and alarm prioritization are essential methods for addressing these issues. These models prioritize alarms based on user feedback, thereby alleviating the burden on users to manually inspect alarms. However, they often encounter limitations related to efficiency and issues such as false generalization. While learning-based approaches have demonstrated promise, they typically incur high training costs an

Parallel fault diagnosis using hierarchical fuzzy Petri net by reversible and dynamic decomposition mechanism

Authors: Yinhong XIANG, Kaiqing ZHOU, Arezoo SARKHEYLI-HÄGELE, Yusliza YUSOFF, Diwen KANG, Azlan Mohd ZAIN

The state space explosion, a challenge analogous to that encountered in a Petri net (PN), has constrained the extensive study of fuzzy Petri nets (FPNs). Current reasoning algorithms employing FPNs, which operate through forward, backward, and bidirectional mechanisms, are examined. These algorithms streamline the inference process by eliminating irrelevant components of the FPN. However, as the scale of the FPN grows, the complexity of these algorithms escalates sharply, posing a significant ch

Active inference of protocol state machines from incomplete message domains

Authors: Maohua GUO, Yuefei ZHU, Jinlong FEI

Inferring protocol state machines from observable information presents a significant challenge in protocol reverse engineering (PRE), especially when passively collected traffic suffers from message loss, resulting in an incomplete protocol state space. This paper introduces an innovative method for actively inferring protocol state machines using the minimally adequate teacher (MAT) framework. By incorporating session completion and deterministic mutation techniques, this method broadens the ra

Neural mesh refinement

Authors: Zhiwei ZHU, Xiang GAO, Lu YU, Yiyi LIAO

Subdivision is a widely used technique for mesh refinement. Classic methods rely on fixed manually defined weighting rules and struggle to generate a finer mesh with appropriate details, while advanced neural subdivision methods achieve data-driven nonlinear subdivision but lack robustness, suffering from limited subdivision levels and artifacts on novel shapes. To address these issues, this paper introduces a neural mesh refinement (NMR) method that uses the geometric structural priors learned

Data-driven intermittent connection fault diagnosis for complex topology DeviceNet based on Bayesian inference

Authors: Longkai WANG, Yong LEI

As the topology of DeviceNet in industrial automation systems grows more complex and the reliability requirement for industrial equipment and processes becomes more stringent, the importance of network troubleshooting is increasingly evident. Intermittent connection (IC) faults frequently occur in DeviceNet systems, impairing production performance and even operational safety. However, existing IC troubleshooting methods for DeviceNet, especially those with complex topologies, cannot directly ha

E2MN: human-inspired end-to-end mapless navigation with oscillation suppression and short-term memory

Authors: Yinan Yang, Zhiye Wang, Xuan Kong, Peng Zhi, Dapeng Zhang, Rui Zhou, Qingguo Zhou

Robotic navigation in unknown environments is challenging due to the lack of high-definition maps. Building maps in real time requires significant computational resources. Nevertheless, sensor data can provide sufficient environmental context for robots’ navigation. This paper presents an interpretable and mapless navigation method using only two-dimensional (2D) light detection and ranging (LiDAR), mimicking human strategies to escape from dead ends.

Prototype-guided cross-task knowledge distillation

Authors: Deng LI, Peng LI, Aming WU, Yahong HAN

Recently, large-scale pretrained models have revealed their benefits in various tasks. However, due to the enormous computation complexity and storage demands, it is challenging to apply large-scale models to real scenarios. Existing knowledge distillation methods require mainly the teacher model and the student model to share the same label space, which restricts their application in real scenarios. To alleviate the constraint of different label spaces, we propose a prototype-guided cross-task
