We consider the problem of enumerating all maximal flexible patterns in an input sequence database for the class of flexible patterns, where a maximal pattern (also called a closed pattern) is the most specific pattern among the equivalence class of patterns having the same list of occurrences in the input. Since our notion of maximal patterns is based on position occurrences, it is weaker than...

“Cochranella” megista is an Endangered and rarely encountered species of glass frog that, until now, had been only registered in the Colombian Andes. Here we report this for first time Ecuador, expanding its known distribution ca. 530 km south original range. Additionally, include C. a molecular phylogeny unambiguously place genus Nymphargus, resulting new combination. Habitat both countries fr...

We consider the problem of timing analysis in the presence of known false paths. The main difficulty in adaptation of classical breadth-first search to the problem is that at each node one has to store the number of delays which is proportional to that of false paths going through the node. We propose a reduction technique that allows one to drastically reduce the number of delays to store. In ...
