    A Surrogate-based Generic Classifier for Chinese TV Series Reviews
    Ma, Yufeng; Xia, Long; Shen, Wenqi; Zhou, Mi; Fan, Weiguo (2016-11-21)
    With the emerging of various online video platforms like Youtube, Youku and LeTV, online TV series' reviews become more and more important both for viewers and producers. Customers rely heavily on these reviews before selecting TV series, while producers use them to improve the quality. As a result, automatically classifying reviews according to different requirements evolves as a popular research topic and is essential in our daily life. In this paper, we focused on reviews of hot TV series in China and successfully trained generic classifiers based on eight predefined categories. The experimental results showed promising performance and effectiveness of its generalization to different TV series.

    Use of a GPS-Embedded Accelerometer to Evaluate the Complexity of the Running Gait. Part 2: Effects of Fatiguing Activity
    Tegarden, David P.; Williams, Jay H.; Jaskowak, Daniel J. (2019-01-03)
    In the companion study, we report a new approach for analyzing gait complexity and the structure of gait variability (12). Previous studies show that the fractal scaling index (FSI) determined using detrended uctuation analysis (DFA) is reduced by neuromuscular disorders (6) as well as low back pain, fatigue, injury and overtraining (2, 5, 8, 10), indicating a less healthy gait (1). On the other hand, physical training increases DFA (9).
