The roots and rhizomes of Aster tataricus L. f (Zi-wan) is a traditionalChinese medicine, which has been used for relieving cough and resolving phlegm. Previousinvestigation of the species resulted in the isolation and identification of triterpenes,triterpenoid saponins, cyclic pentapeptides, and oligopeptides. We have also reported thepolyphenols and a dipeptide isolated from the species. In this paper, the isolation and structureelucidation of three anthraquinones, chrysophanol (1), physciori (2), and emodin (3), are described.Chrysophanol and physcion were isolated from family Composi-tae for the first time. 展开更多

The fuzzy logic, which is a technique of the artificial intelligence, rises as a result of studies based on simulating the human brain. It is a type of logic that recognizes more than simple true and false values. Linguistic variables can be represented with degrees of truthfulness and falsehood by using fuzzy logic. Like other artificial intelligence techniques, the fuzzy logic is used in many different areas. In computer game industry, it can be used to develop artificial intelligence based games. In this paper, the author discusses about usage of the fuzzy logic technique in computer games and developed a basic game based on the fuzzy logic. In this game, a computer controlled character can behave differently according to changing situations. 展开更多
