The hydrogen bonding between Q53 and the second conformation of carbo- xylate of Gly ... in two distinct conformations in E53QbsSHMT-Gly. In one conformation, the carbox- ylate group forms hydrogen bonds with R357, as in bsSHMT-Gly [12]. In the second conformation, the carboxylate .....

Expressions of PAL are related to expressions ... memory component attempts to understand the input in terms of its empirical knowledge, predict what happens next, and reorganize its knowledge based on new observations.

We also study and compare conditional random ... given the observation sequence and label sequence, and the conditional expectation given the observation sequence alone. With the Markov assumption in Eq. (2), these expectations can be c...
