The equilibrium carbon storage capacity of the terrestrial biosphere has been investigated by running the Lund-Potsdam-Jena Dynamic Global Vegetation Model to equilibrium for a range of CO2 concentrations and idealized climate states. Local climate is defined by the combination of an observation-based climatology and perturbation patterns derived from a 4×CO2 warming simulations, which are line...

The increase in civil world fleet ship emissions during the period 2000-2007 and the effects on key tropospheric oxidants are quantified using a global Chemical Transport Model (CTM). We estimate a substantial increase of 33% in global ship emissions over this period. The impact of ship emissions on tropospheric oxidants is mainly caused by the relatively large fraction of NOx in ship exhaust. ...

Background: The link prediction issue is one of the most widely used problems in complex network analysis. Link prediction requires knowing the background of previous link connections and combining them with available information. The link prediction local approaches with node structure objectives are fast in case of speed but are not accurate enough. On the other hand, the global link predicti...

Economists are often interested in estimating averages with respect to distributions of unobservables, such as moments individual fixed-effects, or average partial effects discrete choice models. For quantities, we propose and study posterior (PAE), where the is computed conditional on sample, spirit empirical Bayes shrinkage methods. While usefulness for prediction well-understood, a justifica...
