Numerous clinical anticancer drugs are obtained from natural plants and Hedyotis diffusa Willd (EEHDW) has been used as a major component in Traditional Chinese medicine formulas since a long time. Ethanol extracts of EEHDW have been shown to possess various biological activities including anticancer function in vitro. Our earlier studies have shown that(More)
Imperialist Competitive Algorithm (ICA) is a new population-based evolutionary algorithm. It divides its population of solutions into several sub-populations, and then searches for the optimal solution through two operations: assimilation and competition. The assimilation operation moves each non-best solution (called colony) in a sub-population toward the(More)
Local search is commonly used in a populationbased evolutionary algorithm to fine tune the quality of the solutions in the population. However, because local search is a costly process, previous work often suggests applying local search only to the current best solution instead of all of the solutions in the population. Imperialist Competitive Algorithm(More)
Language is an enormous barrier to global e-commerce. Internet users favor visiting or shopping on Web sites presented in their native language. This research proposes a shopbot with a multilingual ontology to overcome this language barrier. The shopbot, called WebShopper, collects product data from online vendors over the Web and enables customers to(More)
Transparent display is one of the main technologies in next-generation displays, especially for augmented reality applications. An aperture structure is attached on each display pixel to partition them into transparent and black regions. However, diffraction blurs caused by the aperture structure typically degrade the transparent image when the light from a(More)
This paper utilizes non-Fourier two-temperature heat conduction model to investigate the temperature field in nanometer-sized thin films irradiated by an ultrashort-pulse laser. Ultrashort-pulse laser processing for nanometer-sized devices is usually applied in MEMS and nanotechnology. For ultrashort-pulse laser interaction with metals, the two-temperature(More)
This paper analytically investigates scattering and absorption of a polymer microparticle for laser. Micrometer- and nanometer-sized particles possess characteristic physical and chemical properties different from those of bulk materials. Based on the measurement of radiation pressure exerted on a particle, the absorption analysis of a polymer microparticle(More)
