Tryptophan has been widely used as a probe of protein environment and dynamics. Proper interpretation of the experimental results requires a detailed understanding of tryptophyl photoprocesses, so much effort has been made to understand the fluorescence decay of zwitterionic tryptophan. For a review of these efforts, see ref. [l] . It is now well established that the fluorescence decay of trypt...

In this paper, we extend the construction of a fuzzy subgroup generated by a fuzzy subset to $L$-setting. This construction is illustrated by an example. We also prove that for an $L$-subset of a group, the subgroup generated by its level subset is the level subset of the subgroup generated by that $L$-subset provided the given $L$-subset possesses sup-property.

In this paper, we first discuss the structure of the Ramond N = 2 superconformal algebras. Then we classify the modules of the intermediate series over Ramond N = 2 superconformal algebra.

L-systems are parallel generative grammars, used to model plant development, with the results usually interpreted graphically. Music can also be represented by grammars, and it is possible to interpret L-systems musically. We search for simultaneous ‘pleasing’ graphical and musical renderings of L-systems.
