TL;DR: In this paper, the effect of different hydrogen equations of state (including new first-principles computations) on Jupiter's core mass and heavy element distribution is detailed. And the results of simple cooling models of our solar system's planets, and show that more complex thermal evolution models may be necessary to understand their cooling history.
Abstract: We discuss our current understanding of the interior structure and thermal evolution of giant planets. This includes the gas giants, such as Jupiter and Saturn, that are primarily composed of hydrogen and helium, as well as the “ice giants,” such as Uranus and Neptune, which are primarily composed of elements heavier than H/He. The effect of different hydrogen equations of state (including new first-principles computations) on Jupiter’s core mass and heavy element distribution is detailed. This variety of the hydrogen equations of state translate into an uncertainty in Jupiter’s core mass of 18M

. For Uranus and Neptune we find deep envelope metallicities up to 0.95, perhaps indicating the existence of an eroded core, as also supported by their low luminosity. We discuss the results of simple cooling models of our solar system’s planets, and show that more complex thermal evolution models may be necessary to understand their cooling history. We review how measurements of the masses and radii of the nearly 50 transiting extrasolar giant planets are changing our understanding of giant planets. In particular a fraction of these planets appear to be larger than can be accommodated by standard models of planetary contraction. We review the proposed explanations for the radii of these planets. We also discuss very young giant planets, which are being directly imaged with ground- and space-based telescopes.

TL;DR: In this paper, the electronic structure of a jellium-Si interface was calculated using a Jellium density corresponding to Al and self-consistent Si pseudopotentials.
Abstract: The electronic structure of a jellium-Si interface is calculated using a jellium density corresponding to Al and self-consistent Si pseudopotentials. Local densities of states and charge densities are used to study states near the interface. At the Si surface, a high density of extra states is found in the energy range of the Si fundamental gap. These states are bulklike in jellium and decay into Si with a high concentration of charge in the dangling-bond free-surface-like Si state. Truly localized interface states are also found but at lower energies. The calculated barrier height is in excellent agreement with recent experimental results.

TL;DR: This article used meta-analysis to combine, explain, and summarize these disparate estimates of common currency trade effects, and concluded that a currency union increases bilateral trade by between 30 and 90%.
Abstract: . Thirty-four recent studies have investigated the effect of currency union on trade, resulting in 754 point estimates of this effect. This paper uses meta-analysis to combine, explain, and to summarize these disparate estimates of common currency trade effects. The hypothesis that there is no effect of currency union on trade is easily and robustly rejected at standard significance levels. Combining these estimates implies that a currency union increases bilateral trade by between 30 and 90%. Although there is evidence of publication selection, there is also evidence of a genuine positive trade effect beyond publication bias.

TL;DR: Compared the effect of various alcohol dehydrogenases (ADH) for the last step of the isobutanol production, E. coli has the yqhD gene which encodes a broad-range ADH and shows better production than ADH2, a result confirmed by activity measurements with isobutyraldehyde.
Abstract: Biofuels synthesized from renewable resources are of increasing interest because of global energy and environmental problems. We have previously demonstrated production of higher alcohols from Escherichia coli using a 2-keto acid-based pathway. Here, we have compared the effect of various alcohol dehydrogenases (ADH) for the last step of the isobutanol production. E. coli has the yqhD gene which encodes a broad-range ADH. Isobutanol production significantly decreased with the deletion of yqhD, suggesting that the yqhD gene on the genome contributed to isobutanol production. The adh genes of two bacteria and one yeast were also compared in E. coli harboring the isobutanol synthesis pathway. Overexpression of yqhD or adhA in E. coli showed better production than ADH2, a result confirmed by activity measurements with isobutyraldehyde.
