... comparatives and non-comparatives by extracting only comparatives from text documents. Then we classify the comparatives into seven types. 3.1 Extracting comparative sentences from text documents ... CS-candidates in text documents, and then SVM eliminates the non -comparative sentences from the candidates. Thus, all of the sentences are divided into two cl...

To determine their subunit compositions, bands i–vi were excised and subjected to SDS⁄ PAGE on 6% and 14% gels (Fig. 5B,C), followed by densito- metric analyses. Bo...

NRG1 and NRG2 bind to both ERBB3 and ERBB4, whereas NRG3 and NRG4 only bind to ERBB4 [3]. Although these ligands show redundancy, heparin- binding-EGF is the o...
