(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The first known interstellar object 'Oumuamua exhibited a nongravitational acceleration that appeared inconsistent with cometary outgassing, leaving radiation pressure as the most likely force. Barring the alien lightsail ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We characterize and monitor subsidence of the Bursa Plain (southern Marmara region of Turkey), which has been interpreted as resulting from tectonic motions in the region. We quantify the subsidence using Interferometric ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Digital volume correlation analysis of time‐resolved X‐ray microtomography scans acquired during in situ triaxial compression of Green River shale cores provided time series of 3‐D incremental strain fields that elucidated ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In this work, an in-situ growth approach has been employed to fabricate Al:ZnO/Cu2O/Cu and Al:ZnO/ZnO/Cu2O/Cu heterojunctions using direct current (DC) and radio frequency (RF) magnetron sputtering technique in a controlled ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The electrical and chemical properties of the titanium dioxide (TiO2) coated spirals grown by the atomic layer deposition (ALD) technique in two different temperatures of 150 °C and 300 °C are studied. The thickness of the ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We apply inline electron holography to investigate the electrostatic potential across an individual BaZr0.9Y0.1O3 grain boundary. With holography, we measure a grain boundary potential of −1.3 V. Electron energy loss ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The material system Li-Ta-O is a promising candidate for thin-film solid-state electrolytes in Li-ion batteries. In the present study, we have varied the Li content x in LixTaOy thin films grown by atomic layer deposition ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Understanding what limits the growth of marine copepods is important for modeling food web dynamics and biogeochemical cycles in the ocean. We use a state-of-the-art stoichiometric model that explicitly represents metabolic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Centuries of work have highlighted the importance of several characteristics on fracture propagation. However, the relative importance of each characteristic on the likelihood of propagation remains elusive. We rank this ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)Chromium (II) fluoroperovskites A CrF 3 ( A = Na + , K + ) are strongly correlated Jahn-Teller active materials at low temperatures. In this paper, we examine the role that the A -site ion plays in this family of ...

JASPAR 2024: 20th anniversary of the open-access database of transcription factor binding profiles (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)JASPAR (https://jaspar.elixir.no/) is a widely-used open-access database presenting manually curated high-quality and non-redundant DNA-binding profiles for transcription factors (TFs) across taxa. In this 10th release and ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2013)Since the 1980s nuisance growth of the aquatic macrophyte Juncus bulbosus has been observed in an increasing number of rivers and lakes in Europe. Freshwater acidification, lake liming, as well as the impact of hydropower ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The carbon vacancy (VC) is a major limiting-defect of minority carrier lifetime in n-type 4H-SiC epitaxial layers and it is readily formed during high temperature processing. In this study, a kinetics model is put forward ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We herein report tests at high temperatures of a 4-leg oxide thermoelectric generator consisting of two pairs of p-type Ni0.98Li0.02O (Li–NiO) and n-type Zn0.98Al0.02O (Al–ZnO), assembled with various conducting perovskite ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)La2Ce2O7 is known to be a disordered fluorite, i.e., 50% La-doped CeO2, exhibiting oxide ion conduction with contributions from protons in wet atmospheres and minority electrons under reducing conditions. Here, we report ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Geophysical granular flows exert basal forces that generate seismic signals, which can be used to better monitor and model these severe natural hazards. A number of empirical relations and existing models link these signals' ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The mechanics of magma emplacement in the Earth's crust corresponds to the flow of a viscous fluid into a deforming solid. The Earth's crust through which magma is emplaced is visco-elasto-plastic, and field observations ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Climate and land-use changes are leading to impacts on individual ecosystems as well as shifts in transfer dynamics between interconnected systems. At the land-ocean interface, changes in riverine inputs of organic matter ...
