Simulated trawling: Exhaustive swimming followed by extreme crowding as contributing reasons to variable fillet quality in trawl-caught Atlantic cod (Gadus morhua)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-18)Trawl-caught Atlantic cod (Gadus morhua) often yield highly variable fillet quality that may be related to capture stress. To investigate mechanisms involved in causing variable quality, commercial-sized (3.5±0.9 kg) Atlantic cod were swum to exhaustion in a large swim tunnel and subsequently exposed to extreme crowding (736±50 kg m<sup>-3</sup>) for 0, 1 or 3 hours in an experimental cod-end. The ... -
Explaining decisions of deep neural networks used for fish age prediction
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-19)Age-reading of fish otoliths (ear stones) is important for the sustainable management of fish resources. However, the procedure is challenging and requires experienced readers to carefully examine annual growth zones. In a recent study, convolutional neural networks (CNNs) have been demonstrated to perform reasonably well on automatically predicting fish age from otolith images. In the present study, ... -
Cluster Detection Mechanisms for Syndromic Surveillance Systems: Systematic Review and Framework Development
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-26)Background:The time lag in detecting disease outbreaks remains a threat to global health security. The advancement of technology has made health-related data and other indicator activities easily accessible for syndromic surveillance of various datasets. At the heart of disease surveillance lies the clustering algorithm, which groups data with similar characteristics (spatial, temporal, or both) to ... -
Local refinement of ERBS curves
(Journal article; Peer reviewed; Chapter, 2013-12-31)Expo-rational B-splines (ERBS) provide a blending type construction where local functions at each knot are blended together by infinitely smooth basis functions. In this work we consider some specific ERBS curves that are approximations of parametric curves. We study local refinement to increase flexibility by inserting local control curves at points of interest on the ERBS curve. Inserting knots ... -
Physical activity and mental distress among adolescents. Results from the Tromsø Study: Fit Futures
(Doctoral thesis; Doktorgradsavhandling, 2020-08-21)The onset of experiencing symptoms of mental distress, such as depression and anxiety, is most common during the adolescent years, and is concurrent with a measured decrease in physical activity levels. Research on the association between physical activity and mental distress among adolescents find contradictory results, and the field is in need of more longitudinal research with validated measurements. ... -
Quantification of porosity in composite resins delivered by injectable syringes using X-ray microtomography

Four products were examined, which comprised universal composites (Herculite XRV Ultra, Ceram.X ... -
A Co-Scheduling Problem of Ship Lift and Ship Lock at the Three Gorges Dam
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-16)Due to the unprecedentedly increasing demands of waterway transportation on the Yangtze River during the latest years, traffic congestion at the Three Gorges Dam (TGD) has becoming a serious problem. In busiest seasons, a vessel may need to wait up to 3 days for passing the TGD via the ship lift or the five-stage ship lock. In order to improve the navigation efficiency and the utilization of passing ... -
Car tire crumb rubber: Does leaching produce a toxic chemical cocktail in coastal marine systems?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-23)Crumb rubber granulate (CRG) produced from end of life tires (ELTs) is commonly applied to synthetic turf pitches (STPs), playgrounds, safety surfaces and walkways. In addition to fillers, stabilizers, cross-linking agents and secondary components (e.g., pigments, oils, resins), ELTs contain a range of other organic compound and heavy metal additives. While previous environmental impact studies on ... -
‘Fixing my life’: young people’s everyday efforts towards recovery from persistent bodily complaints
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-23)Little is known about the perspectives of young people suffering from medically unexplained symptoms. This study aims to explore the experiences and strategies of young Norwegians related to incipient and persistent health complaints affecting everyday life functioning. The study draws on field notes, video material and interview transcripts from a multi-sited ethnographic study of healthcare services ... -
A combined histo-score based on tumor differentiation and lymphocytic infiltrate is a robust prognostic marker for mobile tongue cancer
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-30)We wanted to evaluate the prognostic value of common histopathological variables in a large cohort of patients with cancer in the mobile tongue as such information can be important for treatment stratification of the individual patient, especially for patients with low-stage disease. In addition, we wanted to investigate whether an alternative scoring model with fewer options would compromise the ... -
Nephronectin promotes breast cancer brain metastatic colonization via its integrin-binding domains
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-22)This study demonstrates a role for the extracellular matrix protein nephronectin (NPNT) in promoting experimental breast cancer brain metastasis, possibly through enhanced binding to- and migration through brain endothelial cells. With the introduction of more targeted breast cancer treatments, a prolonged survival has resulted during the last decade. Consequently, an increased number of patients ... -
Methods for Predicting the Likelihood of Safe Fieldwork Conditions in Harsh Environments

(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-14)We propose a deep-learning framework to detect and categorize oil spills in synthetic aperture radar (SAR) images at a large scale. Through a carefully designed neural network model for image segmentation trained on an extensive dataset, we obtain state-of-the-art performance in oil spill detection, achieving results that are comparable to results produced by human operators. We also introduce a ... -
Photographs of the Soviet Settlements on Svalbard
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-01)Photographic recordings from the 1950s–1970s give us glimpses into the Soviet settlements on Svalbard during the Cold War period. The majority of these pictures have been taken by Norwegians during friendly exchanges with the inhabitants in Barentsburg and Pyramiden, and demonstrate how important culture and sport were as a contact zone. These pictures also testify that the Soviets invested more ... -
