Electroencephalogram-based emotion recognition (EEG-ER) has received increasing attention in the fields of health care, affective computing, and brain-computer interface (BCI). However, satisfactory ER performance within a bi-dimensional and non-discrete emotional space using single-trial EEG data remains a challenging task. To address this issue, we(More)
BACKGROUND The hOGG1 Ser326Cys polymorphism is associated with lung cancer risk, but there are limited data regarding an association between the APE1 Asp148Glu polymorphism and lung cancer. Biological evidence shows that the hOGG1-Cys allele results in less DNA repair activity; however, this is not associated with p53 mutation in lung cancer. Therefore, we(More)
Manganese superoxide dismutase (MnSOD) is an antioxidant enzyme responsible for the elimination of superoxide radical. The role of MnSOD in tumor progression in different human cancers is still controversial. In the present study, MnSOD expression in lung cancer cells was explored by knockdown or overexpression using transfection of a short hairpin RNA(More)
Metastatic spread of cancer cells portends a poor prognosis and mortality for lung cancer patients. Hypoxia-inducible factor-1α (HIF-1α) enhances tumor cell motility by activating the epithelial-to-mesenchymal transition (EMT), which is considered a prerequisite for metastasis. Recent studies of microRNA involvement in cancer invasion and metastasis have(More)
Quantitative analysis of user behavior calls for automated collection of large amount of log data over time. In this paper, we present a service platform for logging and analyzing mobile user behaviors. We have implemented a log collection service which records all user operations on the mobile unit. The collected data are transmitted to a remote server(More)
The epithelial-to-mesenchymal (EMT) transition is a prerequisite for conferring metastatic potential during tumor progression. microRNA-30a (miR-30a) expression was significantly lower in aggressive breast cancer cell lines compared with non-invasive breast cancer and non-malignant mammary epithelial cell lines. In contrast, miR-30a overexpression reversed(More)
NKX2-1 plays a dual role in lung adenocarcinoma progression, but the underling mechanism is not fully understood. In the present study, we provide evidence that NKX2-1 directly regulates p53 transcription, and in turn, NKX2-1 elevates the mutant p53/NF-Y complex to up-regulate IKKβ transcription in p53-mutant cells, but NKX2-1-mediated wild-type p53(More)
With the rapid evolution of mobile devices, the usage patterns of applications on these devices also change over time. The topic of user behaviors on mobile devices such as smart phones has attracted much attention in recent years. In this work, we have developed an experimental platform that can log and analyze all user operations on a smart phone that is(More)
