Without loss of gen- erality, we assume metric scores are bounded be- tween 0 and 1, with 1 being perfect. Each hypoth- esis h can be...

... experimented on a document clustering task. 1 Introduction In natural language processing (NLP) and text min- ing, clustering methods are crucial for various tasks such as document clustering. ... authors also justified their method by showing that with feature hashing, dot- product is unbiased, and the length of each vector is well-preserved with high probability under some conditions. Pl...

... scenarios, there were sig- nificant numbers of ESDs both with the minimum length of 5 and the maximum length of 16 and ev- erything in between. Combined with the fact that 93% of all individual event descriptions ... two phrases if they are semantically similar, i.e. it should cost more to align ‘exit’ with ‘eat’ than ‘exit’ with ‘leave’. Thus we take a measure of se- mantic (dis)simil...

... 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...

... cisplatin DNA treatment correlated with the occurrence of sequence motifs forming stable bifunc- tional adducts with the drug (namely, GG and AG doublets) within the target sites. 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...

TetR i2 -E15A L17V shows repression to 12.5% with 4-ddma-atc and to 58% with atc, thus showing only fivefold improved repression with 4-ddma-atc over atc. A similar...
