... that CDO alone did not increase the extent of staining. However, in cells that had been cocultured with CDO and a cytotoxic drug, staining was significantly increased, indicating the presence of ... this protein, as seen in HCT116 cells, resulted in the absence of enhanced cell growth inhibition. The central role of p21 waf1 in mediating senescence is currently being investigated in...

... & Norvig, 1995). 3 Training Method 3.1 General Setting Our training set I consists of candidate inferences from the parse trees in the training data. From each training inference i ∈ I we generate ... regularization penalty by decreasing λ (Steps 1.6 and 1.7) and continue training. In this way, instead of choosing the best λ heuristically, we can optimize it during a single training r...

... subtilisin in the presence of 98% (w/w) of KCl was tentatively explained by either rigid salt structure protecting the enzyme in organic solvents or polar environment of salt helping in maintaining ... in enzymology. Lyophilization involves [28,33] (a) initial freezing, (b) primary drying (in which ice separated from the protein phase is removed by sublimat- ion) and (c) secondary dr...

... Introduction This paper brings together two strands of research that have recently emerged in the field of probabilis- tic parsing: crosslinguistic parsing and lexicalized parsing. Interest in parsing models ... vary considerably in size: our FTB training set was about 8,500 sentences large, while the standard training set for the PTB is about 40,000 sentences in size, and the Negra tr...
