The present study recorded both behavioral data and event-related brain potentials to examine the effectiveness of a perception-only training and a perception-plus-production training procedure on the intentional and unintentional perception of lexical tone by native English listeners. In the behavioral task, both the perception-only and the(More)
OBJECTIVES High-risk human papillomavirus (hrHPV) is the primary cause of cervical cancer. As Chlamydia trachomatis is also linked to cervical cancer, its role as a potential co-factor in the development of cervical intraepithelial neoplasia (CIN) grade 2 or higher was examined. METHODS The placebo arms of two large, multinational, clinical trials of an(More)
migration greatly expanded over the past decades. Consequently, migrant and left-behind children have greatly increased in number. Using data from the 2011 Survey on Social Integration of Migrant Children in Wuhan, China, this study examined psychological and behavioral problems of migrant and left-behind children. Results showed that left-behind and(More)
Microorganisms decompose organic substrates to obtain energy. This process releases carbon dioxide (CO2) and is the main cause of soil carbon release in terrestrial ecosystems. Fluctuations in microbial composition significantly affect net CO2 emissions in forests. Because factors are cross-correlated, addressing how they affect soil respiration (Rs), both(More)
The method of fault diagnosis of rolling bearings based on wavelet packet transform and support vector machine is presented. The key to fault bearings diagnosis is feature extracting and feature classifying. Wavelet packet transform, as a new technique of signal processing, possesses excellent characteristic of time-frequency localization and is suitable(More)
A corrosion sensor for monitoring the corrosion state of cover mortar was developed. The sensor was tested in cement mortar, with and without the addition of chloride to simulate the adverse effects of chloride-contaminated environmental conditions on concrete structures. In brief, a linear polarization resistance method combined with an embeddable(More)
Capsaicin has multiple pharmacological activities including antioxidant, anticancer, and anti-inflammatory activities. However, its clinical application is limited due to its poor aqueous solubility, gastric irritation, and low oral bioavailability. This research was aimed at preparing sustained-release matrix pellets of capsaicin to enhance its oral(More)
erature. However, current studies lack empirical evaluations of social work students' core compe-tencies. Using 332 social work undergraduates in China, this paper examined core competences of social work undergraduates in China and compared the results with that in the United States. The results revealed that Chinese students' core competences were(More)
