... at the N- and C-termini. A comparison of the b-turn structure of cER with the similar region in the crystal structure of rat and human CD2 was carried out. In the rat CD2 crystal structure, the ... with the higher inhibitory activity of the cEL peptide and the very low inhibitory activity of the cYT peptide compared to other peptides. The flanking res...

... the pair of events. More formally, E = (S, s 0 , F, L, T) is a model where S is the set of states, s 0 ∈ S is the initial state, F ⊆ S is the set of final states, L is the set of edge labels and ... is the set of transitions. We note that it is the responsibility of the learning algorithm to discover the correct number of states. We treat the task of disco...
