The last decade has represented a significant time in European Union (EU) energy policy. The mounting consequences of climate change have pushed the EU to the forefront of the clean energy transition. However, challenges such as the Crimean crisis in 2014, the COVID-19 pandemic and the ongoing war in Ukraine have also had implications on priorities in EU energy policy. This study aims to further t

In the coming decades, the twin energy and digital transitions will require the rapid scaling and deployment of renewable energy technologies and advanced technologies within ‘critical raw materials’ (CRMs) are essential components. At the same time, as CRM reserves are heterogeneously distributed, concentrated in a few countries with refining in even fewer still, demand is expected to outstrip su

The Arctic has increasingly emerged as a geopolitical horizon shaped by environmental, security and economic transformations. As sea ice melts and military and commercial interests materialise, questions arise about how the region is discursively constructed by various stakeholders. With the Arctic Council in flux, alternative forums have gained significance as sites for dialogue and public diplom

A search for heavy Majorana neutrinos in scattering of same-sign W boson pairs in proton–proton collisions at s=13 TeV at the LHC is reported. The dataset used corresponds to an integrated luminosity of 140 fb−1, collected with the ATLAS detector during 2015–2018. The search is performed in final states including a same-sign ee or eμ pair and at least two jets with large invariant mass and a large

The observation of the electroweak production of single-top-quarks is made using 255 pb−1 of proton-proton collision data recorded at s=5.02 TeV with the ATLAS detector at the Large Hadron Collider. An event selection is used to identify single-top-quark candidates arising from t-channel production with the top quark decaying semi-leptonically. Events passing the selection are then used to measure

Purpose: Tropomyosin receptor kinase (TRK) fusions are detected in less than 2% of central nervous system tumors. There are limited data on the clinical course of affected patients. Experimental Design: We conducted an international retrospective cohort study of patients with TRK fusion–driven central nervous system tumors. Results: A total of 119 patients were identified. The median age at the ti
