| Based on a recently developed security assessment methodology using automatic training data generation software and neural networks, a composite security boundary visualization approach is proposed for power system operations. This approach can draw a single continuous boundary given multiple individual security problems. It can be conveniently accessed(More)
Liver disease is an important cause of illness and death, consisting of primarily viral hepatitis, alcoholic liver disease and nonalcoholic fatty liver disease. Among them viral hepatitis resulted from hepatitis B virus is predominant, especially in China. Estimated by The World Health Organization (WHO), chronic infection with HBV is a major cause of(More)
This paper presents a method to predict the postcontingency security margin using radial basis function networks with a fast training method. A genetic-based feature selection tool is developed to obtain the most predictive attributes for use in RBF networks. The proposed method is applied to a thermal overload problem for demonstration. The simulation(More)

Chemotherapy is a notable method for the treatment of breast cancer. Numerous genes associated with the sensitivity of cancer to chemotherapy have been found. In recent years, evidence has suggested that a particular structure termed Holliday junction (HJ) plays a crucial role in cancer chemosensitivity. Targeting HJ resolvases, such as structure-specific(More)
Knowledge of security boundaries is becoming more and more important as transmission lines are operating closer and closer to their capacities in today's deregulated environment. On-line visualization of security boundaries using intelligent techniques provides an eeective methodology for this problem. Feature selection , i.e., critical parameter selection,(More)
Nucleos(t)ide analogs (NAs) are widely used in the treatment of hepatitis B virus (HBV) and human immunodeficiency virus (HIV). The mutation L210W of HIV‑1 reverse transcriptase (RT) is one of the six principal mutations which confer in vivo resistance to zidovudine. Due to the similar 3D‑structure and high conservation between HIV‑RT and HBV‑RT, the(More)
