(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Agricultural, forestry‐impacted and natural catchments are all vectors of nutrient loading in the Nordic countries. Here, we present concentrations and fluxes of total nitrogen (totN) and phosphorus (totP) from 69 Nordic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Issues related to use of metallic interconnects in oxide thermoelectric generators (TEGs) need to be addressed to secure performance and durability. Metal interconnects suffer from high cost of noble metals or chemical ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract The Fennoscandian Shield in central Sweden displays a complex structural and compositional architecture that is mainly related to the Proterozoic history of the Baltica paleocontinent. In its western ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Humeri of Pessopteryx nisseri and vertebrae referred to Cymbospondylus sp. are described from the Lower Saurian niveau at Marmierfjellet, Spitsbergen. This is the most well-preserved Cymbospondylus material described from ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The implantation of aluminum into 4H-SiC is studied using secondary ion mass spectrometry. In particular, two-dimensional concentration profiles are obtained, which allow the investigation of lateral straggling and its ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Subarctic peatlands underlain by permafrost contain significant amounts of organic carbon. Our ability to quantify the evolution of such permafrost landscapes in numerical models is critical for providing robust predictions ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2021)Low lattice thermal conductivity is essential for high thermoelectric performance of a material. Lattice thermal conductivity is often computed using density functional theory (DFT), typically at a high computational cost. ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)II–IV nitrides and their alloys represent an earth-abundant and potentially cost-efficient alternative to the well-developed AlN-GaN-InN system. A major drawback with the II–IV nitrides is that ZnSnN2, the lowest band gap ...
