The filamentous nitrogen-fixing cyanobacterium Anabaena sp. PCC 7120 differentiates specialized cells, heterocysts, that fix atmospheric nitrogen and transfer the fixed nitrogen to adjacent vegetative cells. Reciprocally, vegetative cells transfer fixed carbon to heterocysts. Several routes have been described for metabolite exchange within the filament, one of which involves communicating chan...

Transformations of object-oriented methods are a prevalent object-oriented programming technique, but in many languages they are not supported at runtime. Therefore it can be hard to apply method transformations for incremental or experimental software evolution, or other problems that require runtime software behavior adaptation. The goal of the work presented in this paper is to provide a bet...
