... binary classification simply deals with the is/is-not relationship and will have difficulty when two responses with similar feature values are clas- sified differently. With preference ranking, viola- tions ... appropriate candidates. 4 Experiments To compare with the prior approach of Pinchak and Lin (2006), we use a set of what and which questions with question focus (questions with...

... allosteric DNAzyme with dual RNA-cleaving and DNA-cleaving activities is very challenging. We used an in vitro-selected pistol-like (PL) DNAzyme as a DNA scaffold for designing a DNAzyme with dual catalytic ... As compared with PL DNAzyme, DRc DNA- zyme function seemed to have decreased sensitivity to the reaction temperature. DRc DNAzyme exhibited a broad functional range for temperatu...

Binding of ... protein with cer- tain response elements can be controlled by changes in DNA topology inducing formation of non-B DNA structures within the binding sites [11,12]. Interactions of p53 with DNA...
