Research ArticleOpen accessIn the author namesA Generalized Discrete-Time Long Memory Volatility Model for Financial Stock ExchangeChin Wen CheongWe proposed a simple way to combine a few long memory models in financial market volatility modeling using daily, range and high frequency data. This model was able to fit the return, range of daily return or realized volatility under a parametric heavy-tailed distribution. Model was flexible to include additional volatility information as the contemporaneous variables. Empirical results found that … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the author namesFuzzy Automata Induction using Construction MethodMo Z. Wen, Wan MinRecurrent neural networks have recently been demonstrated to have the ability to learn simple grammars. In particular, networks using second-order units have been successfully at this task. However, it is often difficult to predict the optimal neural network size to induce an unknown automaton from examples. Instead of just adjusting the weights in a network of fixed topology, we adopt … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2006 · 7,213 accessesView PDFCite
Research ArticleOpen accessIn the author namesTAGN-IDC: Implicit Discrete Constraints for Tsunami Aware Graph Neural Networks in Spatial Evacuation RoutingSularno, Wendi Boy, Putri Anggraini et al.Tsunami evacuation route requires rapid identification of safe evacuation paths under dynamically changing hazard conditions. A major challenge is incorporating hard binary road-blockage constraints caused by tsunami inundation while maintaining end-to-end differentiability for deep learning models. Existing approaches commonly rely on continuous relaxations or stochastic sampling techniques, which either compromise physical feasibility or increase computational complexity. This study proposes the … …Journal of Computer Science, Vol. 22, Issue 9 · 24 Sep 2026 · 711 accessesView PDFCite

Research ArticleOpen accessIn the author namesDihydroartemisinin Attenuates HBV-Induced Proliferation and Migration in LO2 cells via EMT Pathway ModulationYingde Nong, Caifang Ma, Wei Huang et al.Dihydroartemisinin (DHA), a derivative of artemisinin, possesses well-documented anti-inflammatory properties. This study investigated the inhibitory effects of DHA on hepatitis B virus (HBV)-induced cellular alterations in LO2 cells and elucidated underlying molecular mechanisms. Serum interleukin-6 (IL-6) levels were measured in HBV patients and analyzed for correlations with HBsAg, anti-HBs, and HBeAg. In vitro, LO2 cells were infected with clinical HBV … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 8 Jan 2026 · 2,079 accessesView PDFCite
