(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Context. Ambipolar diffusion is a physical mechanism related to the drift between charged and neutral particles in a partially ionized plasma that is key to many different astrophysical systems. However, understanding its ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Context. Ambipolar diffusion is a process occurring in partially ionised astrophysical systems that imparts a complicated mathematical and physical nature to Ohm’s law. The numerical codes that solve the magnetohydrodynamic ...

(Research report / Forskningsrapport, 2001)We continue our study of the concepts of amenability and co-amenability for algebraic quantum groups in the sense of A. Van Daele and our investigation of their relationship with nuclearity and injectivity. One major tool ...
-
(Research report / Forskningsrapport, 2001)We define concepts of amenability and co-amenability for algebraic quantum groups in the sense of A. Van Daele [21]. We show that co-amenability of an algebraic quantum group always implies amenability of its dual. Various ...
-
(Master thesis / Masteroppgave, 2017)We build a mathematical model for the risk involved when a person makes a binding fixed-price offer to buy or sell something that fluctuates in value. This situation often arises in financial markets, where such an offer ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Elevated reactive nitrogen (Nr) deposition is a concern for alpine ecosystems, and dry NH3 deposition is a key contributor. Understanding how emission hotspots impact downwind ecosystems through dry NH3 deposition provides ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The ecological conservation and high-quality development of the Yellow River basin (YRB) has been adopted as a major national strategy of China. However, the YRB is still afflicted by floods. Here, we proposed a flood risk ...

Amyloid-beta treated organotypic hippocampal slices as a model system of Alzheimer´s diseaseRestricted Access (Master thesis / Masteroppgave, 2022)
-
(Master thesis / Masteroppgave, 2022)The accumulation of pathogenic amyloid proteins is a common theme of many neurodegenerative diseases, including Alzheimer's disease, the most common form of dementia. One of the main hallmarks of the disease is the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Genomic assignment tests can provide important diagnostic biological characteristics, such as population of origin or ecotype. Yet, assignment tests often rely on moderate- to high-coverage sequence data that can be difficult ...
-
(Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2020)Non-orthogonal multiple access (NOMA) is consid-ered an important candidate for the next-generation cellular networks to address the issue of exponentially growing data traffic from technologies like the Internet of Things ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Hybrid hydropower and floating photovoltaic power generation has far-reaching effects on the intertwined water, food and energy (WFE) nexus, but the complementary operation is fundamentally challenging especially under ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Individual trait variation is essential for populations to cope with multiple stressors and continuously changing environments. The immense number of possible stressor combinations and the influence of phenotypic variation ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Understanding the spreading process of new products provides valuable knowledge that can be used for effective marketing. The ability to make early prediction of success or failure is a great advantage in innovation ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Coherent scatter echoes from disintegrating meteors and from the unstable ionospheric E‐region can overlap considerably between 90 and 110 km altitudes. As the physical origin of plasma irregularities produced by ...
