... experiments, U343 cells were transfected with DR5 siRNA, treated with or without 2.5 lm MG132, and subjected to western blot analysis (Fig. 4A). Transfection with siRNA against DR5 resulted in a ... DR5 upregulation by PIs in glioma cells. To determine this, U343 cells were transfected with siRNA duplexes targeted against CHOP or with nontargeting scram- bled siRNA, and then treat...

... word senses, even many new words are not included inside. Learning word senses from free text will help us dispense of outside knowledge source for defining sense by only discriminating senses ... which treated senses as clusters of words occurring in sim- ilar contexts. Their algorithm initially discovered tight clusters called committees by grouping top n words similar with tar...

With proper software design, such op- timizations ... suit the application. We presume that readers are famil- iar with declarative descriptions of inference algo- rithms, as well as with semiring parsing (Goodman, 1999...
