| 2 | Complexity and characteristic frequency studies in ECG signals of mice based on multiple scale factors显示文摘Existing methods of physiological signal analysis based on nonlinear dynamic theories only examine the complexity difference of the signals under a single sampling frequency.We developed a technique to measure the multifractal characteristic parameter intimately associated with physiological activities through a frequency scale factor.This parameter is highly sensitive to physiological and pathological status.Mice received various drugs to imitate different physiological and pathological conditions,and the distributions of mass exponent spectrum curvature with scale factors from the electrocardiogram (ECG) signals of healthy and drug injected mice were determined.Next,we determined the characteristic frequency scope in which the signal was of the highest complexity and most sensitive to impaired cardiac function,and examined the relationships between heart rate,heartbeat dynamic complexity,and sensitive frequency scope of the ECG signal.We found that all animals exhibited a scale factor range in which the absolute magnitudes of ECG mass exponent spectrum curvature achieve the maximum,and this range (or frequency scope) is not changed with calculated data points or maximal coarse-grained scale factor.Further,the heart rate of mice was not necessarily associated with the nonlinear complexity of cardiac dynamics,but closely related to the most sensitive ECG frequency scope determined by characterization of this complex dynamic features for certain heartbeat conditions.Finally,we found that the health status of the hearts of mice was directly related to the heartbeat dynamic complexity,both of which were positively correlated within the scale factor around the extremum region of the multifractal parameter.With increasing heart rate,the sensitive frequency scope increased to a relatively high location.In conclusion,these data provide important theoretical and practical data for the early diagnosis of cardiac disorders. | YANG XiaoDong HE AiJun LIU Peng SUN TongFeng NING XinBao | 2011 | Science China(Life Sciences)2011，54，6： | 1 |

| 5 | HUNK inhibits cargo uptake and lysosomal traffic in the caveolar pathway via the AGAP3/ARF6显示文摘Endocytosis is a crucial cellular process that takes up cargos by enclosing them in membrane-bound vesicles,and transports cargos to different parts of the cell,such as the lysosomes[1].Endocytosis is classified into several mechanistically and morphologically pathways,including clathrin-mediated endocytosis(CME)and caveolae-mediated endocytosis(CavME)[1,2]. | Siyuan Jiang Xiaoqi Han Tihui Liu Ying He Zidong Zhao Tongfeng Liu Shuwen Cheng Jihang Zhang Liqiang Duan Yajuan Liu Tianyou Cheng Yong Liu Qinong Ye Shan Gao | 2024 | Science Bulletin2024，69，2： | 0 |
| 6 | Overview of Digital Image Restoration显示文摘Image restoration is an image processing technology with great practical value in the field of computer vision.It is a computer technology that estimates the image information of the damaged area according to the residual image information of the damaged image and carries out automatic repair.This article firstly classify and summarize image restoration algorithms,and describe recent advances in the research respectively from three aspects including image restoration based on partial differential equation,based on the texture of image restoration and based on deep learning,then make the brief analysis of digital image restoration of subjective and objective evaluation method,and briefly summarize application of digital image restoration technique in the future and prospects,provide direction for the research on image after repair. | Wei Chen Tingzhu Sun Fangming Bi Tongfeng Sun Chaogang Tang Biruk Assefa | 2019 | Journal of New Media2019，1，1： | 0 |
