To address the problem of low repair efficiency of single- and double-disk of localized horizontal array code, this paper retains the original advantages of horizontal array code, transforms it on the basis of RDP 2D array code, and proposes a 2D array code model based on nested structure - NRDP (Nested Rows Diagonal Parity Code). The overall layout of the NRDP code is the same as that of the RDP code. However, when deploying data columns, the NRDP code deploys the RDP code of one prime number level smaller as a whole in the data columns of the NRDP code, forming a nested relationship. The increased redundant data reduce the repair overhead and error recovery time. Through theoretical analysis, NRDP has good compiled code complexity, improves the problem of uneven reading and writing during disk repair, and reduces the total amount of data that needs to be read during single- and double-disk failures, improving the success rate of single- and double-disk repair. The experimental results show that compared with RDP, LRRDP, and DRDP, NRDP can save 7.03%-30.01% of the single-disk failure repair time and 14.79%-26.51% of the dual-disk repair time. © 2024 IEEE.

ViGT: proposal-free video grounding with a learnable token in the transformer

Science China(information Sciences) 2023年第10期66卷 196-212页

The video grounding(VG) task aims to locate the queried action or event in an untrimmed video based on rich linguistic descriptions. Existing proposal-free methods are trapped in the complex interaction between video and query, overemphasizing cross-modal feature fusion and feature correlation for VG. In this paper, we propose a novel boundary regression paradigm that performs regression token learning in a transformer. Particularly, we present a simple but effective proposal-free framework, namely video grounding transformer(ViGT), which predicts the temporal boundary using a learnable regression token rather than multi-modal or cross-modal features. In ViGT, the benefits of a learnable token are manifested as follows.(1) The token is unrelated to the video or the query and avoids data bias toward the original video and query.(2) The token simultaneously performs global context aggregation from video and query ***, we employed a sharing feature encoder to project both video and query into a joint feature space before performing cross-modal co-attention(i.e., video-to-query attention and query-to-video attention) to highlight discriminative features in each modality. Furthermore, we concatenated a learnable regression token [REG] with the video and query features as the input of a vision-language transformer. Finally, we utilized the token [REG] to predict the target moment and visual features to constrain the foreground and background probabilities at each timestamp. The proposed ViGT performed well on three public datasets:ANet-Captions, TACoS, and YouCookⅡ. Extensive ablation studies and qualitative analysis further validated the interpretability of ViGT.

IEEE Access 2025年 13卷 91046-91064页

Accurate pest identification is crucial for ensuring both high quality and high yield in rice production. This paper proposes RicePest-YOLO, a practical and generalizable model designed for agricultural pest detection, based on structural optimization and lightweight strategies applied to the YOLOv8 architecture. The model is specifically tailored to address the challenges of rice pest images, such as small insect size, complex backgrounds, and high inter-class similarity. In particular, it integrates ODConv and the BiFPN structure into the backbone and neck of YOLOv8n, enhancing the model's ability to extract features from rice pest images. Subsequently, the Shape-IoU loss function is employed to enhance the model's sensitivity and precision in target recognition. Furthermore, to facilitate the deployment of the new algorithm on embedded terminal devices, we applied Layer Adaptive Magnitude Pruning and Knowledge Distillation techniques for a lightweight model. The effectiveness of the proposed model was evaluated on common rice pest datasets. Experimental results demonstrate that the proposed model outperforms YOLOv8n, achieving an mAP@0.5 of 94.3%, and an mAP@0.5:0.95 of 67.3%, with 2.7% improvement in mAP@0.5 and 1.2% improvement in mAP@0.5:0.95. Comparison experiments with state-of-the-art models further demonstrated the proposed approach's superiority. The model's generalization and robustness were tested on the Pests dataset and the Paddy Rice Pest dataset. Results indicated a 2.6% and 3.0% improvement in mAP@0.5, and a 2.8% and 4.0% increase in mAP@0.5:0.95, respectively. Additionally, Experimental results show that the lightweight version of RicePest-YOLO reduced parameters by 48.1% and GFLOPs by 50%, with only a marginal decrease of 0.4% in mAP@0.5. The results validate that the proposed model is not only effective and efficient but also robust and lightweight, making it a promising solution for rice pest detection and offering valuable support for pest man

This paper mainly focuses on the symmetric encryption and decryption of shared data. In the traditional symmetric encryption technology, sharing an identical key is safe for both communication parties, which is not flexible enough for large-scale data exchange though. The symmetric encryption and decryption of shared data means that multiple users can use the same key to encrypt or decrypt data, so as to achieve data security protection and improve transmission efficiency. At present, the research of symmetric encryption and decryption of shared data has made some progress, but there are still some challenging problems. For example, problems like how to avoid key leakage and how to ensure the efficiency of decryption process need to be further addressed. In this study, chaotic mapping and substitution methods are used to solve these problems. First, we transform the original data into a new random sequence by way of chaotic mapping, and then convert it back to the original. This method can effectively prevent key leakage and improve the decryption speed without affecting the data transmission. Secondly, we use the idea of permutation to design a new decryption algorithm, which can complete the decryption task through simple computational operations without slowing down the decryption speed. © 2023 IEEE.

Lung Computed Tomography (CT) images play an important role in the diagnosis and treatment of patients with COVID-19. However, manually identifying lesions in CT images is very time-consuming and requires specialized medical knowledge. The accuracy and integrity of the existing models are still not ideal due to the reasons such as scattered distribution, small lesions and blurred boundaries. Therefore, we propose a segmentation model based on U-Net architecture by combining Mirror-symmetry Boundary Guided (MBG) module and then adding Spatial Attention Dilation (SAD) convolution Module, called MSU-Net. The SAD module uses spatial attention mechanism and dilated convolution and multi-scale feature extraction strategy to enhance the network’s ability to recognize small lesions. The MBG module further enhances the model’s ability to capture more complex context information and boundary details, making the model more robust and able to effectively deal with the challenges of fuzzy boundaries. The proposed method has shown superior performance in terms of the Dice coefficient, Hausdorff distance, and Sensitivity on the publicly available COVID-19 CT dataset. © 2024 SPIE.

This paper mainly studies the symmetric encryption and decryption technology for multi-user shared data in cloud storage environment. With the popularity of cloud storage technology, more and more users store multi-user shared data on third-party cloud platforms. In order to protect the privacy and integrity of multi-user shared data, encryption technology has become an important means to deal with cloud security challenges [1]. The traditional multi-user shared data encryption technology has some problems in the scenario of multi-user shared data. For example, it is difficult to restrict the access to multi-user shared data after decryption. Therefore, this paper proposes a symmetric encryption technology for multi-user shared data based on access control, which uses attribute encryption to achieve controllable access to multi-user shared data, and uses group cryptography and obfuscation technology to ensure the confidentiality and integrity of multi-user shared data. The experimental results show that this technology not only ensures the security of multi-user data sharing, but also has high efficiency and user friendliness. As a result, it can meet the encryption requirements in large-scale multi-user data sharing scenarios. The research of this technology has certain reference significance for the security improvement of cloud storage field. © 2023 IEEE.
