Furthermore, we investigated the prediction performance on the cases where the corresponding biological activities increased or decreased by at least three orders of magnitude because these cases are relevant to the activity cliff phenomenon in medicinal chemistry. Finally, we selected four cases that ...
In spite of the extensive studies over several decades, the (bio)chemistry and pharmacology of Cr(III) are still poorly understood. The initially proposed active low molecular weight Cr(III)-binding peptide (chromodulin) has never been reproducibly identified8. It is generally believed that Cr(II...
The paper highlights the research lines which are urgent to plan the soundest energy mix for each region by considering the underground performances case by case: a worldwide mapping, by GIS tools of this kind of information could be strategic for all the “world energy management” authorities...
It should be noted that China's political scheme has a top-down structure, such that the provincial legislation cannot be independent of the national system. Once the central government adopts a national strategy to support the blue energy economy, full cooperation among provinces will be ...
