Aggregate R&D spending has grown steadily in the US over the long term. In addition, as we showed in Section 2.7, profitability explains little of the cross-sectional variation in R&D spending. In this section, we confirm our earlier findings by focusing on shorter term changes in R&D ...
At low/moderate concentrations, oxidants induce subtle changes in signalling intracellular pathways in response to changes of intra- and extracellular environmental conditions, ensuring physiological function of the cell [26]. In wound healing involving biomaterials, they orchestrate the different phases of...
Rosenbluth index from other methods of determining the level of market concentration stands out very sensitive reaction to the changes in market shares and the company’s position in the market. Change in firm size in the market also determines the different importance of market share when ...
