“…Many factors can destroy this balance, so that the pleural fluid increases, that is, pleural effusion. PE is a common medical problem, and its pathogenesis includes (Imre et al 2020 ; Liu et al 2020 ; Metintas et al 2010 ; Ye et al 2020 ): The increase of pleural capillary hydrostatic pressure is caused by cardiac insufficiency, increased blood volume and venous obstruction. Low protein synthesis or excessive loss of protein results in hypoproteinemia, which leads to the decrease of colloidal osmotic pressure.…”

Lung cancer is the most fatal cancer in the world. Early detection, diagnosis and treatment of lung cancer is an important means to improve the survival rate of lung cancer patients. The early signs of lung cancer are small pulmonary nodules, so early detection and timely treatment of pulmonary nodules are of great significance to save the lives of lung cancer patients. With the progress of medical CT technology, a large number of image data obtained by medical CT examination are increasing, which can provide more organ and tissue information, but also bring a great burden to doctors. Therefore, the detection technology of thoracic spectrum signal is a key point. The chest cavity is a non adjustable resonator with a fixed volume and space, which is located in the chest ribs and below the vocal cords. According to the principle of resonance in physical theory, the resonance characteristics are mainly related to the size of the cavity surrounded by a certain hardness of the outer wall. Therefore, some researchers believe that the volume of the chest cavity is related to the resonance of the chest cavity. Although in recent years, some teams have combined deep learning and machine learning to improve signal feature extraction, which makes signal feature extraction easier and more efficient, most of them are still based on IQ data for signal modulation recognition. Therefore, this paper studies the visual feature extraction model based on artificial intelligence and thoracic echo spectrum, and the experimental results show the effectiveness of this method compared with the latest approaches.

“…The authors report significant improvements both in power consumption and other design metrics to support low power quality rendering. Finally, a paper by Martin et al [10] proposes a method to simplify big graphs using spectral graph theory, in a way suitable for efficient drawing of large graphs at varying levels of detail. Their approach outperforms state-of-theart graph simplification methods while working with any graph drawing algorithm.…”

“…GraphVisual supports the D3-force-directed layout [7] which is an implementation and adaptation of Dwyer's [12] algorithm, fast multipole multilevel method (FM 3 ) [14], ForceAtlas2 [20] which focuses on network spatialization, OpenOrd [22] which is designed for large graphs, and Yifan Hu's algorithm [18] which combines a multilevel approach, together with Barnes and Hut octree force calculation [2] and an adaptive cooling scheme for the general force model for efficient high-quality graph drawing. Among non-force-directed layouts, GraphVisual supports a spectral layout which uses the spectrum of the graph to assign node positions [19], a circular layout which simply aligns nodes along a circle, and a random layout which assigns node positions randomly. In addition, GraphVisual supports two special layouts, geographical layout and bipartite layout, for drawing graphs with geographical information and bipartite graphs, respectively.…”
