A theory is described based on resonant thermal diffusion waves in the sun that explains many details of the paleotemperature record for the last 5.3 million years. These include the observed periodicities, the relative strengths of each observed cycle, and the sudden emergence in time for the 100 thousand year cycle. Other prior work suggesting a link between terrestrial paleoclimate and solar...

   In this study, the change of porosity and roughness of carbon nanostructures, including fullerenes, carbon nanotubes and graphene was investigated according to oxidation process. The effect of oxidation was more sensible on smoother surface of nanostructures. Oxidation increases surface roughness of graphene up to 5.2% and porosity up to 35.2%. While, roughness of hummers graphene is 13....

Abstract We investigate structural change in the PR China during a period of particularly rapid growth 1998-2014. For this, we utilize sectoral data from World Input-Output Database and firm-level Chinese Industrial Enterprise Database. Starting with correlation laws known literature (Fabricant’s laws), which empirical regularities hold at level show that many these correlations cannot be recov...

Abstract Using a broad panel of advanced economies, we document that increases in GDP per capita are associated with systematic shift the composition value added to sectors intensive high-skill labour, process label as skill-biased structural change. It follows further development these economies leads an increase relative demand for skilled labour. We develop quantitative two-sector model this...
