Imipenem hydrolysis by the L1 and the NDM-1 metallo-beta-lactamases: QM/MM structures of the stationary points
<p>Stationary points (transition states and minima) for the hydrolysis reactions of the imipenem in the active sites of the L1 and NDM-1 metallo-beta-lactamases. The reactions occure in three elementary steps each. For the NDM-1 there are two compeeting pathways leading to the different products. Enamine and imine forms of the hydrolyzed imipenem may form and those are marked with "N" and "C", respectively, according to the atom being protonated at the last step. Structures are calculated at the QM(PBE0-D3/6-31G**)/MM(AMBER) level.</p>
EBSD Dataset of the Alpha and Beta Phase Orientations for Hot-rolled Ti-6Al-4V
<p>This is an EBSD dataset for hot-rolled Ti-6Al-4V alloy. It includes the EBSD maps of the starting material, and materials have been rolled at nine different temperatures (825°C, 865°C, 895°C, 915°C, 935°C, 950°C, 960°C, 975°C, 1020°C) to three reductions (50%, 75%, and 87.5%). Each rolled material was sampled from transverse direction (TD) and rolling direction (RD) and EBSD maps were taken from both directions. Materials rolled at 825°C and 915°C were further rolled to 94% reduction and EBSD maps were taken from TD. The information of each EBSD data is given in the metadata file in each folder.</p> <p>For materials rolled above 915°C, the beta phase was reconstructed with a software based on Burger's orientation relationship.</p> <p>The Matlab script for plotting EBSD maps, pole figures and ODFs can be downloaded <a href="https://zenodo.org/record/8328717">here</a>.</p>

Mesophotic coral ecosystems of French Polynesia are hotspots of alpha and beta generic diversity for scleractinian assemblages
<p>Revealing how diversity varies across the depth gradient is key to understanding the role of mesophotic coral ecosystems in the functioning of coral reefs. We examined how alpha and beta generic diversity of scleractinian coral assemblages vary across a wide depth gradient for coral reefs. We studied generic diversity patterns of scleractinian corals at sixteen sites in eight islands of three archipelagos in French Polynesia, as derived from the analysis of photo-quadrats, across the seafloor from shallow to lower mesophotic depths (6 to 120 m) and on a wide geographic scale. Our sampling considered quantitative coral cover to explore the patterns of alpha and beta components of diversity across depth and horizontal space. We show that in French Polynesia, mesophotic coral ecosystems host higher alpha and beta generic diversity than shallow reefs despite decreasing coral cover with depth. The variation of coral genus richness across the depth gradient is mainly driven by a mid-domain effect with a peak at 40 m depth. At the same time, we found that the turnover of coral genera across islands (i.e., spatial beta diversity) increased steadily along the depth gradient. Our findings report the first quantitative results of coral cover and diversity from mesophotic coral ecosystems in French Polynesia and also present one of the few existing studies to examine the broad breadth of the mesophotic depth gradient. We demonstrate that mesophotic depths can host unexpectedly high generic richness of scleractinian coral assemblages. At the same time, we showed that increasing depth increases the differences in generic diversity composition across islands, whereas shallow reefs are similar in between. While a single island could conserve shallow regional biodiversity, mesophotic depths containing the richest diversity require site-specific measures, suggesting that considering these mesophotic depths in conservation is necessary to maintain regional diversity.</p>
