  1. ABSTRACT While many plant lineages display remarkable diversity in morphological form, our understanding of how phenotypic diversity, or disparity, arises in relation to genomic evolution over geologic scales remains poorly understood. Here, we investigated the relationship between phenotypic and genomic evolution in the Fagales, a lineage of woody plants that has been a dominant component of temperate and subtropical forests since the Late Cretaceous. We examine newly generated transcriptomic and trait datasets representing most extant genera and a rich diversity of Cretaceous fossil representatives. Our phylogenomic analyses identify recurrent hotspots of gene duplication and genomic conflict across the order. Our phenotypic analyses showed that the morphospace occupied by Fagales was largely filled by the early Cenozoic, and rates of evolution were highest during the early radiation of the Fagales crown and its major families. These results suggest that Fagales conforms to an “early‐burst” model of disparification, with morphospace being filled early in the order's diversification history, and that elevated levels of phenotypic evolution also often correspond to hotspots of gene duplication. Species diversification appears decoupled from patterns of both phenotypic and genomic evolution, highlighting the multidimensional nature of the evolution of plant diversity across geological timescales.

  2. Abstract The semiconductor tracker (SCT) is one of the tracking systems for charged particles in the ATLAS detector. It consists of 4088 silicon strip sensor modules.During Run 2 (2015–2018) the Large Hadron Collider delivered an integrated luminosity of 156 fb -1 to the ATLAS experiment at a centre-of-mass proton-proton collision energy of 13 TeV. The instantaneous luminosity and pile-up conditions were far in excess of those assumed in the original design of the SCT detector.Due to improvements to the data acquisition system, the SCT operated stably throughout Run 2.It was available for 99.9% of the integrated luminosity and achieved a data-quality efficiency of 99.85%.Detailed studies have been made of the leakage current in SCT modules and the evolution of the full depletion voltage, which are used to study the impact of radiation damage to the modules.
