Background This study aimed to evaluate the clinical and dosimetric factors predictive of acute anal toxicity (AAT) after radiotherapy in prostate cancer (PCa) patients with or without hemorrhoids. Methods We analyzed data from 347 PCa patients (248 cases treated from July 2013 to November 2017 for training cohort and 99 cases treated in 2018 for validation cohort) treated with pelvic radiotherapy...
In order to extract the feature of electroencephalogram (EEG) quickly and efficiently, to improve the classification accuracy rate, band-pass filter and wavelet package were used to get mu and beta rhythms. In the time domain, energy feature was formed by the squared-amplitude of electroencephalogram (EEG) samples over the trials. The subtracted energy value of lead C3 and C4 was averaged by each...
Classification of electroencephalogram(EEG) is a crucial issue for EEG-based brain computer interface(BCI) system. The paper presents a method for EEG classification, where property of event-related desynchronization/synchronization(ERD/ERS) of mu/beta rhythms, The mu/beta rhythms are obtained after filtering and wavelet packet transform. The energy feature is formed by the squared amplitude of the...
