Background:This study presents SIMSleepSM,a novel single-channel electroencephalography(EEG)sleep staging model.It addresses two primary challenges:insufficient modeling of long-range temporal dependencies combined with limited multi-scale feature extraction,and poor accuracy in identifying the N1 stage.Methods:SIMSleepSM extends the SleePyCo architecture through three principal innovations.First,the spatial-channel synergistic attention(SCSA)module is adapted into a 1D variant,SCSA_1D,tailored for EEG signals and inserted into every feature layer of the backbone network.The spatial attention extracts local temporal dependencies across various time scales,whereas the channel attention captures relationships among feature channels.Together these attentions strengthen temporal dependency modeling and emphasize N1-specific features.Second,an interactive convolution block(ICB)is integrated into the feature pyramid.The ICB employs a two-branch interactive convolution to refine multi-scale feature extraction.Finally,a bidirectional Mamba-based classifier is designed.Its bidirectional state space mechanism captures long-range temporal dependencies in the EEG and thereby strengthens representation of sleep-stage dynamics.Results:On the Sleep-EDF-20,Sleep-EDF-78,and Sleep Heart Health Study(SHHS)datasets,SIMSleepSM achieves accuracy values of 88.1%,86.2%,and 84.1%;records macro F1 scores of 82.7%,81.0%,and 77.9%;obtains Cohen's Kappa coefficients of 0.839,0.810,and 0.791;and attains F1-scores on the N1 stage of 53.7%,54.4%,and 50.9%for Sleep-EDF-20,Sleep-EDF-78,and SHHS,surpassing the second-best models by 1.3%,4.0%,and 4.8%,respectively.Conclusion:Experimental results demonstrate that SIMSleepSM outperforms thirteen state-of-the-art baseline models,with particularly notable improvements in N1-stage identification.These results indicate that SIMSleepSM provides an effective and reliable solution for automatic sleep staging using single-channel EEG,highlighting it as a robust and high-performing model. 展开更多

Due to the uncertainty of the factors that influence the network service time and other characters of college student, Bayesian Network is used to model this kind of system. Different algorithms are used for learning Bayesian Networks in order to compare several models. It is suggested that researchers can use Bayesian Networks to explore the potential relationship between variables of complex social problems. The result indicates that learning target and family closeness degree are the key variables which influenced college student＇ s network service time. Origin of student and family economy didn＇ t influence college student＇ s network service time directly. Schools and community should strengthen the education of college students life planning and communication with parents. 展开更多

The features of low earth orbit/medium earth orbit(LEO/MEO)satellite networks routing algorithm based on inter-satellite link are analyzed and the similarities between satellite networks and mobile Ad Hoc network(MANET)are pointed out.The similar parts in MANET routing protocol are used in the satellite network for reference.A new dynamic routing algorithm based on MANET in LEO/MEO satellite networks,which fits for the LEO/MEO satellite communication system,is proposed.At the same time,the model of the algorithm is simulated and features are analyzed.It is shown that the algorithm has strong adaptability.It can give the network high autonomy,perfect function,low system overhead and great compatibility. 展开更多
