Mendeleev’s introduction of the periodic table of elements is one of the most important milestones in the history of chemistry, as it brought order into the known chemical and physical behaviour of the elements. The periodic table can be seen as parallel to the Standard Model in particle physi...

Using 12 vintages (within the 1990–2007 range) from 7 estates of the Bordeaux region, we report that, remarkably, nonlinear dimensionality reduction techniques applied to raw gas chromatograms recover the geography of the Bordeaux region. Using machine learning, we found that we can not only ...

This paradigm works well for most organic compounds but it fails when heavier atoms (e.g.transition metals) are concerned [30]. In fact, the rather elusive outermost shell of these elements, makes the sign of∇2ρ(r) no longer discriminating. For almost all bonds to a transition metal,...
