Instead of focusing on the improvement of a single set of word alignments, ... the test set for the systems built on each set of word alignment in Table 1. Similar to the observation from Table 1, c 2 outperforms c 0 and c 1 , and B + V + S + P with c...

However, due to the sensitivity of the analysis technique for sam- ple size and the small amount of protein ... any species of Heterotardigrada so far investigated. These results expand our current understanding of anhydrobiosis in tardigrades and, for the first time, demonstrate th...
