... dia- logues. Moreover, in most cases, users have knowledge about the task. However, in complex domains things are different. Take for example tutoring. A tutoring dialogue system has to discuss concepts, ... Q14-16 were included to probe user’s post tutoring perceptions. We find a trend that in the NM problems it was easier for users to under- stand the system’s main point...

... protective effects against hypoxia and reoxygenation. This is mainly ascribed to its ability to maintain redox status [17], intervening in the DNA repair system [18–20] and restoring antioxidant capaci- ties ... new insights into the role of pyruvate in tumor cells during hypoxia. We show here that tumor HepG2 cells are inclined to maintain extracellular pyruvate at a constant level...

... domain plays a central role in bundling of F-actin. Taken together, these data identify hhLIM as an actin-binding protein that increases actin cytoskeleton stability by promoting bundling of actin ... of the actin cytoskeleton following its ectopic expression in C2C12 cells, actin depolymerization was induced by cytochalasin B in hhLIM–GFP–transfected C2C12 cells. The actin cytoskelet...

... is to loop through the list L, keeping track of any dominant points. Given a dominant point, it is easy to filter out many points that are dominated by it. After suc- cessive rounds, any remaining ... necessarily pareto-optimal. Algorithm 1 shows the pseudocode. In line 3, we take a point h ∗ and check if it is dominating or dominated in the for- loop (lines 4-8). At least one pareto-o...
