    Study on generation of turbulence-distorted received signals in OAM optical communications obeying dual Johnson S<sub>B</sub>distribution by Chunyi CHEN, Qinqin XIONG, Haiyang YU, Haifeng YAO, Jiaxue SONG, Yan LOU

    Published 2020-11-01
    “…In order to analyze the performance of atmospheric OAM optical communication systems by Monte Carlo method,a method was proposed to simulate turbulence-distorted received signals in OAM optical communications,which possessed the given temporal auto-correlation and obeyed the dual Johnson S&lt;sub&gt;B&lt;/sub&gt;distribution.A Gaussian random sequence with given temporal auto-correlation was first created by using an auto regression (AR) model,and meanwhile a white noise random sample sequence obeying the dual Johnson S&lt;sub&gt;B&lt;/sub&gt;distribution was generated.Then the white noise random sample sequence was rearranged according to the statistical rank of the auto-correlated Gaussian random sequence to match the given temporal auto-correlation.By performing the simulation experiments,it was found that the statistical distribution of the simulated signals was in excellent agreement with the dual Johnson S&lt;sub&gt;B&lt;/sub&gt;distribution,and the temporal auto-correlation of the signals matched the given temporal auto-correlation function.The results demonstrate that the proposed method can be used to simulate time-domain received signals in OAM optical communications impaired by turbulence-induced distortions.…”

    Correlation of Body Mass Index and Waist-Hip Ratio with Severity and Complications of Hyperlipidemic Acute Pancreatitis in Chinese Patients by Lixin Yang, Jing Liu, Yun Xing, Lichuan Du, Jing Chen, Xin Liu, Jianyu Hao

    Published 2017-01-01
    “…Hyperlipidemic acute pancreatitis (HLAP) is characterized by critical condition and high recurrence rate compared with non-HLAP. We conducted this study to investigate the value of body mass index and waist-hip ratio in predicting severity and local complications in HLAP. 96 patients with HLAP were categorized by body mass index and waist-hip ratio, respectively. …”
