In this study we use the most recent version of the ground-to-thermosphere VPCM [1] that includes an ionosphere model, ambipolar diffusion and nitrogen chemistry [2]. This tool allows us to investigate and identify in 3D potential mechanisms responsible for the observed variability in Venus's atmosphere, in the region between 90 km and 130 km altit...

This paper identifies export accelerations at the country pair-product level that are large enough to drive aggregate export growth in the medium run. In a sample of 100 countries, these export “big hits” are rare, less than 2 percent of all export spells, yet account for over two-thirds of export growth in a given country. The paper then explores ...
Abstract This work numerically explores the anisotropy, impact phase wave propagation, buckling resistance, and natural vibration of ultra-high performance concrete (UHPC) and UHPC-steel interpenetrating phase composite (IPC) with triply periodic minimal surfaces (TPMSs), including sheet and solid gyroid, primitive, diamond, and the Schoen I-graph-...
We estimate the tax elasticity of dividends using two recent French re- forms: a hike in the dividend tax rate followed, five years later, by a cut. To follow the cash movements within the balance sheets of households and firms caused by these reforms, we use newly-accessible personal and cor- porate tax registries. Following the tax increase, the ...
