... factor, the graph-based random walk model of ranking sentences would per- form better if we could encode the syntactic and se- mantic information instead of just the bag of word (i.e. TF*IDF) information ... similarity between the sentences in the random walk model for answering complex ques- tions. We argue that for this task, similarity mea- sures based o...

... presence of alternative splicing around the 5¢-end of exon 6 of Meis2 and Meis3 was tested by RT-PCR. The positions of molecular mass markers are shown to the left, and the size in base pairs of the ... the alternative splice site in Meis3, such that both the Meis3.1 and Meis3.2 isoforms were amplified. The relative amount of each splice form as a percentage of t...

... indicated by the average activity of mutants in the central domain of 26% for WAF1 and 34% for MDM2, 71% for NOXA and 61% for p53R2, and around 45% for the other four promot- ers. For some specific ... mutants). To evaluate the performance of the algorithm, test sets were created. We used five-sixths of the data for training and the remaining one-sixth for...
