... using any stop list (NoStop). In this case, the size of the stop list is set to n stop = 10, and the number of seeds n seed = 10 and iterations τ = 20. For both HITS and NoStop, the seeds are selected ... on seed se- lection and stop list construction. We also briefly in- troduce the Espresso bootstrapping algorithm (Pan- tel and Pennacchiotti, 2006) for which...

... human effort. 4 Data for Partial Cognates We performed experiments with ten pairs of par- tial cognates. We list them in Table 1. For a French partial cognate we list its English cognate and ... training sentences. We removed the stop- words from the features. A list of stopwords for English and one for French was used. We ran experiments when we kept the stopwords a...

... solvent. There- fore, the solvation of backbone atoms is much larger for a conformers than for b conformers. Interaction with solvent thus compensates for the destabilization of the a conformation ...

Because glucose is the primary fuel for the CNS and blood glucose and hypothalamic malonyl-CoA levels fall and rise together during food deprivation and refeeding, it was reasoned that glucose ... in feeding behavior and energy expenditure. For example, the hypothalamus can sense and respond to fluctuations in the levels of blood glucose [13], fatty acids [12,14,15]...
