Three typical types of spherical fruits, namely apples, oranges, and pears, have accounted for 40.86 % of the total fruit production in China in 2023. However, there is a huge trade deficit in the import and export trade of fruits in China. Furthermore, grading technology has limited the largest production and consumption of fruits. Appearance indicators, such as size, volume and deformity index, are the main external quality traits of fruits in commercial grading lines. Alternatively, computer vision has been widely used in the field of nondestructive detection of fruits and vegetables, due to the simple operation, non-contact and low cost. The surface information can be obtained to measure the external indicators using two- dimensional images. However, some limitations are still remained to capture the detailed appearance indicators, especially in the high-accuracy measurement. Compared with traditional two-dimensional images, three-dimensional (3D) imaging with the depth information can be beneficial to the appearance indicators of fruits. Among them, binocular structured light is the promising 3D reconstruction with the cost-saving, high-precision and non-contact extraction. This study focuses on spherical fruits, selecting apple, orange, and pear as representative examples, with the aim of constructing binocular structured light imaging to obtain surface contour information. The system was also validated using standard samples. Single-view point cloud reconstruction was performed as well. Three-step phase shifting was used to determine the wrapped phase. While multi- frequency heterodyne was applied to determine the absolute phase. Afterwards, stereo matching, disparity optimization, and point cloud calculation were conducted to obtain a 3D point cloud map. A rotary table was utilized to match the point cloud images from different perspectives to the same coordinate axis. Coarse point cloud registration was also achieved. A complete point cloud was obtained to conduct more precise registration using the iterative closure point (ICP) to obtain. Finally, the 3D reconstruction of spherical fruits was realized. The deformity index of the apple was extracted from the reconstruction image of single-view point cloud using normal vector angle. According to the normal vector angle, the point cloud of the fruit stem position was projected to the bottom of the fruit point cloud image. The complete fruit point cloud was improved to calculate the convex hull of the point cloud for the volume of fruit. The maximum fruit diameter was extracted through oriented bounding box (OBB) bounding box. The experimental results show that the relative error was within 4% in the external dimensions of standard parts using 3D reconstruction. Taking manual measurement as the references, the values of coefficient of determination (R²), root mean squared error (RMSE), and mean absolute percentage error (MAPE) were 0.97, 0.755 mm, and 7.23%, respectively, for the measured apple deformity index. In the volume of spherical fruits, R² was 0.99, RMSE was 6.015 cm³, and MAPE was 1.946%, while those were 0.92, 1.823 mm, and 1.859%, respectively, for the maximum diameter. The 3D reconstruction with binocular structured light can be expected to significantly enhance the accuracy and efficiency in the appearance indicators of spherical fruits. The finding can also provide a valuable tool to improve fruit quality control and grading. [ABSTRACT FROM AUTHOR]

With the widespread application of open-source software across various domains, source code vulnerabilities have led to a series of serious security issues. Given the potential threats these vulnerabilities pose to computer systems, detecting source code vulnerabilities in software to prevent network attacks is a crucial research area. To achieve automated detection and reduce human labor costs, researchers have proposed numerous traditional deep learning-based methods. However, these methods mostly treat source code as natural language sequences and do not adequately consider the structural information of the code, limiting their detection effectiveness. In recent years, methods for detecting source code vulnerabilities based on code graph representation and graph neural networks have emerged. This paper provides a comprehensive review of the application of graph neural networks in source code vulnerability detection and proposes a general framework for source code vulnerability detection based on graph neural networks. Starting from three levels of vulnerability detection granularity: file-level, function-level, and slice-level, the existing methods and relevant datasets are systematically summarized and elucidated. Finally, the challenges faced by this field are discussed, and potential research directions for the future are outlined. [ABSTRACT FROM AUTHOR]

Currently, research on magnetic coupling resonance‑wireless power transmission (MCR‑WPT) primarily concentrates on dual‑transmitter single‑load and triple‑transmitter single‑load systems in a stationary state. This article explores the dual‑transmitter multi‑load low‑speed rotating system. By establishing a theoretical model for the dual‑transmitter multi‑load system and utilizing COMSOL software for simulation, we have constructed a two‑dimensional omnidirectional magnetic resonance wireless energy transmission experimental platform for the rotating receiving end. This platform allows us to verify the impact of various factors on the energy transmission efficiency of the rotating system, including different phase differences of orthogonal transmitting coils, varying numbers of receiving coils and alterations in coil relative positions. The results indicate that when there is a 90° phase difference between the orthogonal dual‑transmitter coils, the system can maintain stable magnetic field transmission characteristics within a fixed distance from the receiving coil. As the number of load coils increases, the fluctuation range of the system’s overall transmission efficiency changes. Notably, the fluctuation is minimal when there are four load coils.

Backgrounds Insomnia is frequent in schizophrenia and is found to be negatively affected by stressful life events, psychotic symptoms and depressive disorder, while the relationship among the four remains understudied in community-dwelling patients with schizophrenia. Objective To analyze the effect of stressful life events on insomnia in community-dwelling patients with schizophrenia, and to explore the mediation effect of psychotic symptoms and depression, so as to provide references for the intervention of insomnia in community-dwelling patients with schizophrenia. Methods From April to June 2023, a sample of 1 105 patients with schizophrenia attending 48 community health centers in Chengdu, Sichuan province and fulfilling the International Classification of Diseases, tenth edition (ICD-10）diagnostic criteria were included. All subjects were assessed using Stressful Life Event Scale (SLEs), Athens Insomnia Scale (AIS), Psychosis Screening Questionnaire (PSQ), and Patient Health Questionnaire Depression Scale (PHQ-9). Spearman correlation analysis was used to determine the correlation among the scales. Then the mediation model was constructed using Smart PLS 4. 0, and tested with partial least squares algorithm and Bootstrap techniques. Results 332 patients (30. 05%） with community schizophrenia were found to have insomnia. AIS scores in patients with schizophrenia were positively correlated with the scores on SLEs, PSQ and PHQ-9 (r=0. 165, 0. 322, 0. 554, P<0. 01). Stressful life events indirectly contributed to insomnia through both separate mediation path and chained mediation path of psychotic symptoms and depressive disorder, and the indirect effect size of 0. 102, 0. 372 and 0. 190 was obtained, accounting for 10. 46%, 38. 15% and 19. 49%, respectively. Conclusion The stressful life events not only directly exert an impact on insomnia, but also indirectly contribute to insomnia through both the separate and chained mediation effect of psychotic symptoms and depressive disorder.
