Hydrogen diffusion into caprock: A semi-analytical solution and a hydrogen loss criterion
(Peer reviewed; Journal article, 2023)Depleted gas reservoirs can provide a gigaton capacity and the necessary infrastructure for large scale hydrogen storage. Therefore, underground storage of hydrogen in these geological formations is considered a valuable ... -
Identification of Arabidopsis Protein Kinases That Harbor Functional Type 1 Peroxisomal Targeting Signals
(Peer reviewed; Journal article, 2022)Peroxisomes are eukaryotic specific organelles that perform diverse metabolic functions including fatty acid β-oxidation, reactive species metabolism, photorespiration, and responses to stress. However, the potential ... -
Importance Sampling-based Transport Map Hamiltonian Monte Carlo for Bayesian Hierarchical Models
(Peer reviewed; Journal article, 2021-06)We propose an importance sampling (IS)-based transport map Hamiltonian Monte Carlo procedure for performing a Bayesian analysis in nonlinear high-dimensional hierarchical models. Using IS techniques to construct a transport ... -
Improved background subtraction and a fresh look at jet sub-structure in JEWEL
(Peer reviewed; Journal article, 2022)Interactions of hard partons in the Quark Gluon Plasma (QGP) created with relativistic heavy ion collisions lead to characteristic modifications of the internal structure of reconstructed jets. A large part of the observed ... -
Influence of material factors on the determination of dynamic moduli and associated prediction models for different types of asphalt mixtures
(Peer reviewed; Journal article, 2022)In a Mechanistic-Empirical (ME) pavement design system, the dynamic modulus is used to characterise asphalt mixtures, which are affected by many factors including environmental conditions and material properties. This study ... -
Influencing factors on petrography interpretations in provenance research – a case-study review
(Peer reviewed; Journal article, 2021)The use of framework petrography is a common initial step in provenance research of sand and sandstone. The data tend to be interpreted based on the three main components quartz, feldspar, and lithic fragments. Surprisingly ... -
Inhomogeneous chiral condensate in the quark-meson model
(Journal article, 2017)The two-flavor quark-meson model is used as a low-energy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μ B. The parameters of the model are determined by matching the ... -
Insights into the potential of the Atlantic cod gut microbiome as biomarker of oil contamination in the marine environment
(Peer reviewed; Journal article, 2019)Background: Microorganisms are widespread in all environments, including in and on animal bodies. The gut microbiome has an essential influence on fish health, and is affected by several persistent and harmful organic and ... -
Investigating responses to object-labels in the domestic dog (Canis familiaris)
(Peer reviewed; Journal article, 2023)Since the dawn of comparative cognitive research, dogs were suspected to possess some capacity for responding to human spoken language. Neuroimaging studies have supported the existence of relevant mechanisms, but convincing ... -
Investigation of glitches induced by single-crystal diamond compound refractive lenses based on crystal orientation
(Peer reviewed; Journal article, 2019)Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to “CRLs”) mainly due to its stability when bathed in strong X-ray radiation. Since CRLs come into operation by ... -
Investigation of the Antiscaling Performance of Phosphonated Chitosan for Upstream Petroleum Industry Application
(Peer reviewed; Journal article, 2021)Scale deposition is one of the main water-based production problems in the upstream oil and gas industry. Few environmentally friendly scale inhibitors show good thermal stability as well as calcium compatibility. We report ... -
Klynger
(Journal article, 2022)Ikke alle datasett har forklaringsvariabler og utfall. Allikevel kan det finnes sammenhenger i dataene som er nyttige å avdekke. På 2010-tallet arbeidet Intervensjonssenteret på Rikshospitalet med å utvikle en dataalgoritme ... -
Kvastad A1. To tidligmesolittiske aktivitetsområder med skivemeisel og -avfall
(Chapter, 2018)Undersøkelsen av Kvastad A1 resulterte i 2210 funn av flint, bergkrystall, kvarts og kvartsitt. To tydelig adskilte aktivitetsområder ble undersøkt, et sørlig og et nordlig. Disse var begge små og med få funn. Selv om ... -
Lil3 dimerization and chlorophyll binding in Arabidopsis thaliana
(Peer reviewed; Journal article, 2015)The two-helix light harvesting like (Lil) protein Lil3 belongs to the family of chlorophyll binding light harvesting proteins of photosynthetic membranes. A function in tetrapyrrol synthesis and stabilization of geranylgeraniol ... -
Log-density gradient covariance and automatic metric tensors for Riemann manifold Monte Carlo methods
(Peer reviewed; Journal article, 2023)A metric tensor for Riemann manifold Monte Carlo particularly suited for nonlinear Bayesian hierarchical models is proposed. The metric tensor is built from symmetric positive semidefinite log-density gradient covariance ... -
Loss of LEUCINE CARBOXYL METHYLTRANSFERASE 1 interferes with metal homeostasis in Arabidopsis and enhances susceptibility to environmental stresses
(Peer reviewed; Journal article, 2022)The biochemical function of LEUCINE CARBOXYL METHYLTRANSFERASE 1 (LCMT1) is to transfer a methyl group from the methyl donor S-adenosylmethionine (SAM) to the catalytic subunits of PROTEIN PHOSPHATASE 2A (PP2Ac), PP4 and ... -
Maleic and Methacrylic Homopolymers with Pendant Dibutylamine or Dibutylamine Oxide Groups as Kinetic Hydrate Inhibitors
(Peer reviewed; Journal article, 2022)Kinetic hydrate inhibitors (KHIs) are applied in oil and gas fields to prevent gas hydrate formation, most often in cold subsea flow lines. The main component in industrial KHI formulations is a water-soluble polymer with ... -
Measuring filter-cake cohesive strength and flowability
