Abstract ：
Addressing the challenges of variable target morphology, small critical regions, and complex background interference in eggplant picking point detection within complex agricultural scenarios, this study proposes MDAD-YOLO (Multi-dimensional Attention and DySample YOLO), a detection model improved based on the YOLOv10n-pose framework. First, the model's cross-dimensional perception ability for fruits and picking points is enhanced by integrating the collaborative mechanism of regional receptive field attention with channel-space joint attention. Next, within the Neck structure, coordinate attention is incorporated to optimize the spatial localization accuracy of fine-grained features, enhancing sensitivity to minute regions such as the fruit stem apex. Additionally, dynamic pixel reorganization is applied to enhance feature map reconstruction details, addressing the detail loss caused by traditional interpolation methods. Finally, cascading adaptive fine-grained channel attention with position-sensitive attention enables multi-level modeling of channel dependencies and collaborative spatial context enhancement. Through a seven-tier validation framework, the model's effectiveness, robustness, and generalizability have been comprehensively demonstrated. Experimental results show that the model achieves 93.6% mAP@50 for object detection, 94.7% mAP@50 and 92.1% mAP for keypoints detection, and an average pixel Euclidean distance error of 19.41 on the self-built eggplant dataset, outperforming YOLOv12 and other high-performance models. Additionally, cross-crop experiments on the pepper dataset showed a 2.1% and 2.7% improvement in mAP for object and picking point detection, respectively, compared to the baseline model, confirming its cross-crop robustness. This study reveals the synergistic enhancement of dynamic upsampling and attention mechanisms in agricultural object detection, providing new insights for lightweight model design in complex scenarios.

Abstract ：
Correspondence pruning aims to identify inliers from an initial set of correspondences with a low inlier ratio. Current Graph Neural Networks (GNNs) based correspondence pruning approaches suffer from feature over-smoothing during information propagation, making it difficult to distinguish inliers from outliers. In addition, Transformer-based methods can model long-range dependencies, but their quadratic complexity limits computational efficiency. To address these issues, we propose MatchMamba, a dual-view correspondence pruning network based on a selective state space model, Mamba. MatchMamba combines the strengths of GNNs and Mamba, enhancing local feature extraction while modeling global context with appropriate complexity. Specifically, to overcome Mamba's limitations in correspondence pruning, such as the lack of local context and unidirectional modeling, we introduce the Cluster Sampling Spatial Mamba (CSSM) block and Correspondence Flip Bidirectional Mamba (CFBM) block. CSSM captures fine-grained local context through the implicit soft assignment and mitigates GNN's over-smoothing using Mamba's selective mechanism. CFBM block leverages Mamba's efficient long-sequence modeling by constructing a pseudo-sequential structure through clustering. It applies forward and backward scanning to enable each correspondence to fully capture contextual information from others, achieving global context modeling with appropriate computational cost. Extensive experiments demonstrate that MatchMamba outperforms current state-of-the-art methods on several challenging tasks. The code is available at https://github.com/Mrwyb/MatchMamba

Abstract ：
Movable antennas (MAs) are a promising technology to achieve a significant enhancement in rate for future wireless networks. The pioneering investigation on near-field directional modulation design for a reconfigurable intelligent surface (RIS)-assisted MA system is presented, with the base station equipped with a MA array. To maximize the secrecy sum rate (Max-SSR) with hardware impairments (HWIs) and imperfect channel state information (CSI), which involves a joint optimization of beamforming vectors for confidential messages and artificial noise (AN), power allocation factors, phase shift matrices, MA positions, and receive beamforming vectors. Firstly, the transmit beamforming vectors and phase shift matrices are iteratively optimized, leveraging leakage theory and phase alignment techniques. Then, two novel algorithms for discrete MA positioning are proposed, respectively, employing uniform and compressed sensing (CS)-based non-uniform grouping strategies. Subsequently, the AN is considered and designed as the additional energy required for zero-space projection, and the receive beamforming vector is derived using the minimum mean square error (MMSE) method. The proposed algorithms have low computational complexity. Simulation results demonstrate the effectiveness of the proposed algorithms. Under HWIs and imperfect CSI, the proposed algorithm can achieve a 28% enhancement in SSR performance while reducing the number of antennas by 37.5% compared to traditional fixed-position antenna (FPA) systems.

Abstract ：
. Pomelo quality grading helps to control the quality of pomelo production and promotes a standardized production. The realization of automated pomelo quality grading relies on the acquisition of several phenotypic parameters, with pomelo volume being a crucial one. Fruit phenotypic features, such as projected area, perimeter, radial distance, and the maximum radius of the tangent circle, are often used to estimate fruit volume through image processing. To enhance the accuracy of volume estimation, this article introduces a pomelo volume estimation model that relies on image features. This model is based on an analysis of the fruits' symmetry axis and combines various features, including the projected area, perimeter, radial distance, and the maximum radius of the tangent circle. In this study, we collected a dataset of 3,200 pomelo images and compared the prediction results under different parameter combinations. After incorporating the parameters associated with the symmetry axis, the root mean square error of volume prediction was 159.82. The coefficient of determination was 0.84, with a mean absolute error of 142.67 and a mean absolute percentage error of 0.23. Notably, the coefficient of determination was improved by 0.26 compared to the results obtained without considering the symmetry axis features. The prediction error falls within the acceptable range, meeting the requirements of practical application. Overall, the proposed method provides a valuable technical reference for pomelo quality grading.

Abstract ：
Cognitive Internet of Vehicles (CIoV) adds the cognitive engine based on traditional Internet of Vehicles (IoV), which can improve spectrum utilization. However, spectrum sensing data falsification (SSDF) attacks pose a threat to CIoV network security. To ensure the full utilization of spectrum resources and protect primary users transmission, this article combines blockchain with CIoV to defend against SSDF attacks in the presence of vehicle users (VUs) entering and leaving the network. Specifically, this article introduces a virtual currency called Sencoins serve as credential for VUs to purchase transmission shares. And this article proposes a reward and punishment mechanism and a hybrid Proof-of-Stake (PoS) and Proof-of-Work (PoW) mining model to thwart the motivation of the VUs to launch SSDF attacks. On this basis, this article investigates the dynamics of SSDF attack strategy choice of VUs, and uses the largest Lyapunov exponent (LLE) to determine the critical value of Sencoins that avoids the system to exhibit chaotic behavior. To describe the uncertainty of the population proportion of VUs that choose different attack strategies due to high-speed movement and the VUs entering and leaving the CIoV network, this article introduces Gaussian white noise into the replication dynamics equation and builds the It & ocirc; stochastic evolutionary game model, and solves it according to the stability judgment theorem of stochastic differential equations and stochastic Taylor expansion. Finally, simulation results verify that the proposed method can quickly and effectively thwart SSDF attacks in the CIoV network. And compared with traditional methods, the proposed method can improve the efficiency of defending against SSDF attacks by 567% and the average throughput by 25%.

Abstract ：
The expression forms of existing probabilistic interval linguistic terms are mostly discrete. When the scale of evaluation information is large and the evaluation information is different, using a probabilistic interval linguistic term set that lists linguistic values one by one has certain limitations in expression. This study proposes a new linguistic expression form called multi-granularity log-normal probabilistic interval linguistic value, which not only effectively processes large-scale linguistic information, but also pays attention to the information distribution characteristics within the interval linguistic term. Firstly, the multi-granularity log-normal probabilistic interval linguistic value is defined, and its algorithms and related properties are introduced. Secondly, a consistency conversion method is proposed for dealing with multi-granularity log-normal probabilistic interval linguistic information. Some excellent properties satisfied by the conversion function effectively avoided information loss during the linguistic transformation process. Subsequently, the attribute ratio Analysis method based on indifference threshold (ITARA) considering the log-normal probabilistic interval linguistic features is developed. By establishing a mixed 0-1 integer programming model based on the cross entropy, interval weights and their indifference thresholds are obtained. The shortcomings of the secondary compromise operator in the traditional combined compromise solution (CoCoSo) method are improved, and the unique advantages of the proposed improvement method are demonstrated through comparative examples. Furthermore, an effective fusion and ranking method for log-normal fuzzy numbers is provided. Finally, the applicability and effectiveness of this method are verified through two species abundance evaluation numerical examples.

Abstract ：
With the rapid development of the Internet of Things (IoT), robust and secure authentication among interconnected devices has become increasingly significant. Existing cryptographic methods, despite their effectiveness, face challenges in scalability, quantum vulnerability, and high computational demands, which are particularly problematic for resource-constrained IoT devices. This paper proposes a novel and lightweight authentication scheme for IoT devices that combines the decentralization of blockchain with the efficiency of lattice-based cryptography to address these security concerns. The proposed scheme employs a decentralized identity management model built on blockchain, eliminating vulnerable central points and enhancing system resilience. For user and device authentication, an efficient lattice-based protocol is introduced, utilizing simplified hash operations and matrix-vector multiplication for key negotiation and authentication. This approach significantly reduces both computational complexity and communication overhead compared to traditional methods such as ECC-based schemes. Specifically, at a 100-bit security level, our scheme achieves authentication and key agreement in approximately 257.401 mu s and maintains a communication cost of 1052 bits per authentication session. Comprehensive performance analyses demonstrate that the proposed scheme can withstand typical cryptographic attacks and offers advantages in quantum computing resistance. Additionally, the blockchain-based design ensures high scalability, making the scheme ideal for large-scale IoT deployments without performance degradation. Experimental results further validate the scheme's practical applicability in resource-constrained IoT environments, highlighting its superior computational response times and lower communication costs compared to existing IoT authentication solutions.

Abstract ：
Owing to its ability to mitigate the double-fading effect by amplifying the reflected signal, the active intelligent reflecting surface (IRS) has garnered significant attention. In this paper, an amplify-and-forward (AF) relay network assisted by a hybrid IRS consisting of both passive and active units is developed. A signal-to-noise ratio (SNR) maximization problem is formulated, where the AF relay beamforming matrix and the hybrid IRS reflecting coefficient matrices for two-time slots need to be optimized. To address the SNR maximization problem, this paper proposes both a high-performance (HP) method and a low-complexity (LC) method. The HP method is based on the semidefinite relaxation and fractional programming (SDR-FP) algorithm, with rank-1 solutions obtained through Gaussian randomization. For the LC method, the amplification coefficient of each active IRS element is assumed to be equal. The SNR maximization problem is then addressed using the whitening filter, generalized power iteration, and generalized Rayleigh-Ritz (WF-GPI-GRR) approach. Simulation results show that compared with the benchmarks, such as the passive IRS-aided AF relay network, the proposed HP-SDR-FP and WF-GPI-GRR methods achieve significant rate improvements. In particular, the HP-SDR-FP and WF-GPI-GRR methods yield more than a 135.0% rate gain when the transmit power Ps of the source is 10 dBm. Furthermore, the proposed HP-SDR-FP method outperforms the WF-GPI-GRR method in terms of rate performance.

Abstract ：
Purpose: Deep learning-based classroom behavior analysis provides new avenues for monitoring teaching quality in higher education. However, it faces challenges such as low detection accuracy, difficulty in recognizing small objects and handling occlusions as well as the difficulty in balancing real-time performance with accuracy. Design/methodology/approach: This paper proposes an improved YOLOv11 method for classroom state recognition, achieving precise classification and behavior detection through the integration of AFGCAttention, SPDConv and RCSOSA modules. AFGCAttention optimizes feature weight allocation through an adaptive fine-grained channel attention mechanism, SPDConv enhances the processing capabilities for small objects and low-resolution images by converting spatial information into depth information and RCSOSA reduces channel redundancy while improving spatial object attention. Findings: Experiments demonstrate that the YOLO-ASR model excels in precision, recall and mAP50. Compared to other You Only Look Once versions, it shows significantly improved detection accuracy and robustness in complex classroom environments, achieving an mAP50 of 93.8% and an mAP50-95 of 73.1%. Time-series analysis reveals dynamic changes in student behavior across teaching phases, including attention fluctuations, mobile phone use and signs of fatigue. Research limitations/implications: By analyzing student behavior across different classroom phases, patterns in mobile phone use and signs of fatigue were identified. These insights help teachers adjust their strategies, highlighting the method’s significance in monitoring teaching quality. Originality/value: This study optimizes the YOLOv11 model for classroom behavior detection by integrating effective modules to enhance performance. It offers a novel approach for quantitatively assessing teaching effectiveness, providing data support for educational reform and advancing intelligent classroom management and innovative teaching models. © 2025, Emerald Publishing Limited.

Abstract ：
Two-view correspondence learning is a fundamental task in computer vision for locating the same object across two different images, and its essence lies in capturing the context from the images. Recent studies employ the standard Convolutional Neural Network (CNN) as the core architecture to capture the context. However, the inherent nature of the CNN's local receptive field and pooling operations can result in the loss of certain semantic context. This can result in the CNN-based correspondence learning methods having an insufficient understanding of the global context, especially on image pairs including challenges like significant viewpoint changes, repetitive structures and weak textures. To address this issue and these challenges, we propose a novel correspondence learning method called Parallel Reinforcement Network (PRNet). Firstly, we design a reinforcement injection block, not only to dynamically refine feature weights by using channel attention mechanism, but also to preserve important details for alleviating over-smoothing issue by strengthening the network's capacity. Secondly, to alleviate the potential issue of overlooking the weak local context by CNN, we propose a parallel fusion block to integrate both shallow and deep features, preserving local details and enhancing global context. We evaluate the performance of the proposed PRNet on an outlier rejection task and a relative pose estimation task. The experimental results demonstrate the proposed PRNet exceeds several existing state-of-the-art methods in various challenging scenarios.
