A comparison of constant false alarm rate object detection algorithms for iceberg identification in L- and C-band SAR imagery of the Labrador Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-15)In this study, we pursue two objectives: first, we compare six different “constant false alarm rate” (CFAR) algorithms for iceberg detection in SAR images, and second, we investigate the effect of radar frequency by comparing the detection performance at C- and L-band. The SAR images were acquired over the Labrador Sea under melting conditions. In an overlapping optical Sentinel-2 image, 492 icebergs ... -
Identification of a core EMT signature that separates basal-like breast cancers into partial- and post-EMT subtypes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-04)Epithelial-mesenchymal transition (EMT) is a cellular plasticity program critical for embryonic development and tissue regeneration, and aberrant EMT is associated with disease including cancer. The high degree of plasticity in the mammary epithelium is reflected in extensive heterogeneity among breast cancers. Here, we have analyzed RNA-sequencing data from three different mammary epithelial cell ... -
Probabilistic Load Forecasting With Reservoir Computing
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-15)Some applications of deep learning require not only to provide accurate results but also to quantify the amount of confidence in their prediction. The management of an electric power grid is one of these cases: to avoid risky scenarios, decision-makers need both precise and reliable forecasts of, for example, power loads. For this reason, point forecasts are not enough hence it is necessary to adopt ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-13)In order to improve the size selectivity and exploitation pattern for cocktail shrimp (Trachypenaeus curvirostris) in shrimp trawl fishery of the South China Sea (SCS), selective properties of four codends were tested and compared. These experimental codends involved two mesh sizes, 30 and 35 mm, and two mesh shapes, diamond-mesh (T0) and diamond-mesh turned by 90 degree (T90), respectively. Our ... -
Utfordringer og muligheter ved bruk av spillelementer i den entreprenørielle læringsprosessen
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-08)Bakgrunn: Hvordan gi studentene en realistisk opplevelse av entreprenørskap innenfor høyere utdanning, er et pedagogisk spørsmål som stadig diskuteres i litteraturen. Spillifisering (gamification på engelsk) har blitt foreslått som en mulig løsning som kan understøtte læringsmålene vi ønsker å oppnå innenfor entreprenøriell læring. Det er lite tidligere forskning som har undersøkt hvordan studenter ... -
Longitudinal cerebrospinal fluid measurements show glial hypo- and hyperactivation in predementia Alzheimer’s disease
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-13)Background - Brain innate immune activation is associated with Alzheimer’s disease (AD), but degrees of activation may vary between disease stages. Thus, brain innate immune activation must be assessed in longitudinal clinical studies that include biomarker negative healthy controls and cases with established AD pathology. Here, we employ longitudinally sampled cerebrospinal fluid (CSF) core AD, ... -
Introductory commentary: Marine conflicts and pathways to sustainability in an era of Blue Growth and climate change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-06)Worldwide, marine conflicts are growing in frequency and intensity due to increasing global demands for resources (Blue Growth) and climate change. This article introduces a collection in Maritime Studies on marine conflicts and pathways to sustainability in an era of Blue Growth and climate change. We posit that while conflict can be problematic, it can also play a positive role in bringing about ... -
Two Nominal Clause-Types in Northern Mansi: An Experimental Study of Language Variation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-10)The paper examines the structure and distribution of two types of nominal/adjectival predicates in the Northern Mansi language. A nominative noun or adjective serves as the predicate in one construction. The other predicate type contains a predicate noun or adjective that takes translative case marking. In both constructions, the stative-like copula ōl- ’be, exist’ can also appear, though ... -
The relevance of the UN Declaration on the Rights of Indigenous Peoples to vibrant, viable and sustainable Sámi communities
(Chapter; Bokkapittel, 2023)The chapter departs from that domestic legislators have demonstrated that they are either incapable of or unwilling to cater for vibrant, viable and sustainable Sámi communities. Indeed, they may counteract this objective. International law on Indigenous rights, on the other hand, is a normative framework promising to be conducive to sustainable Sámi societies. Thus, allowing the international ... -

Reformasjonen på Færøyene - en nordtysk kulturarv?
(Chapter; Bokkapittel, 2023-12-18)The chapter examines the proposition, first advanced by Faroese historian Louis Zachariasen, that the Reformation was introduced to the Faroe Islands by German merchants from Hamburg who held trading privileges and governing authority in the Faroes between ca. 1520 and 1553. Hamburg and the Faroes represented two dramatically different cultural spaces. In addition to obvious differences in language ... -
Environmental DNA of aquatic macrophytes: The potential for reconstructing past and present vegetation and environments
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-29)1. Environmental DNA is increasingly being used to reconstruct past and present biodiversity including from freshwater ecosystems. Macrophytes are especially good environmental indicators, thus their environmental DNA palaeorecord might shed light on past postglacial environments.<p> <p>2. Here, we first review and compare studies that use metagenomics, targeted capture, and various barcoding ... -
The survey of property rights in Sámi areas of Norway—with focus on the Karasjok case
(Chapter; Bokkapittel, 2023)In recognition that the Indigenous Sámi have rights to land and natural resources and that Norway is obliged to identify these rights, Norway has commenced a process of surveying such rights through the 2005 Finnmark Act. The purpose of the survey is to investigate and recognise use and property rights in Finnmark, the core Sámi area in Norway. As of today, six investigations are completed. The ... -
