... as a tight loop of VpUcyt, are indicated by grey stripes and an open rectangle, respectively. The two helices are connected by an interhelical linker. Structural elements are denoted at the bottom ... NMR signals of residues in the tight loop are almost completely quenched by both Mn 2+ and 16-doxylstearic acid, symbolized by the yellow colour in Fig. 10. These loop residues seen in...

... component is represented only by “一一” in the Cangjie codes for “頸” and “勁”. The simplification makes it relatively harder to identify visually similar charac- ters by comparing the actual Cangjie ... costs can be very high. We propose methods for identifying visually similar Chinese characters by adopting and extending the basic concepts of a proven Chinese input method Cangji...

... paper deals with the automatic trans- lation of route descriptions into graphic sketches. We discuss some general prob- lems implied by such inter-mode transcrip- tion. We propose a model ... situations, verbal RDs are often accompanied by sketches, thus participating in a 2- mode representation. A sketch can also function as a route representation by itself. We will first out...
