    • Prisforedrag - Norsk Cardiologisk Selskaps forskningspris 2023 

      Løchen, Maja-Lisa (Journal article; Tidsskriftartikkel; Peer reviewed, 2024)
      Det var en stor ære for meg å motta forskningsprisen. Jeg er takknemlig, ydmyk og stolt overfor Norsk cardiologisk selskap (NCS) og juryen. Få fra miljøet i Tromsø har mottatt prisen, og innenfor fagområdet preventiv kardiologi er det heller ikke mange prismottakere. Jeg ble veldig glad. Det var en stor begivenhet for meg å bli hyllet av mine kolleger, både fra min egen hjertemedisinske avdeling og ...
    • Prototypical Self-Explainable Models Without Re-training 

      Gautam, Srishti; Boubekki, Ahcene; Höhne, Marina Marie-Claire; Kampffmeyer, Michael Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2024)
      Explainable AI (XAI) has unfolded in two distinct research directions with, on the one hand, post-hoc methods that explain the predictions of a pre-trained black-box model and, on the other hand, self-explainable models (SEMs) which are trained directly to provide explanations alongside their predictions. While the latter is preferred in safety-critical scenarios, post-hoc approaches have received ...
    • Sykepleiers erfaring med kommunal akutt døgnenhet i rurale områder 

      Lykkedrang, Hanne; Mehus, Grete (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-01)
      Bakgrunn: Samhandlingsreformen har ført til at flere pasienter mottar behandling i kommunal akutt døgnenhet (KAD) som et alternativ til sykehusinnleggelse. Innføring av KAD i sykehjem i distriktskommuner har gitt sykepleiere i primærhelsetjenesten nye oppgaver og ansvarsområder. Studien er gjennomført i Troms og Finnmark fylke. I distriktskommunene er det store geografiske avstander innad og til ...
    • Primary School Students’ Relations to Physical Education in Northern Norway: Why Do Some Find the Subject Problematic? 

      Johansen, Linda Hjemgård; Nilsen, Tor-Egil; Madsen, Siri Sollied; Andreassen, Svein-Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-08)
      A global discourse surrounding physical education (PE) is shifting towards a stronger emphasis on inclusive practises, but research shows that some students still find the subject problematic. This study explores the relationship between students’ dread of physical education (PE) and overall school satisfaction among sixth graders in Tromsø Municipality, Norway, and identifies factors that might ...
    • AI-Based Cropping of Ice Hockey Videos for Different Social Media Representations 

      Houshmand Sarkhoosh, Mehdi; Dorcheh, Sayed Mohammad Majidi; Midoglu, Cise; Sabet, Saeed Shafiei; Kupka, Tomas; Johansen, Dag; Riegler, Michael Alexander; Halvorsen, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-23)
      Sports multimedia is among the most prominent types of content distributed across social media today, and the retargeting of videos for diverse aspect ratios is essential for a suitable representation on different social media platforms. In this respect, ice hockey is quite challenging due to its agile movement pattern and speed, and because the main reference point (puck) is very small. In this ...

      Automatic analysis of colonoscopy images has been an active field of research motivated by the importance of early detection of precancerous polyps. However, detecting polyps during the live examination can be challenging due to various factors such as variation of skills and experience among the endoscopists, lack of attentiveness, and fatigue leading to a high polyp miss-rate. Therefore, there is ...

      Roaldsen, Marius Håke; Lohne, Vetle Dalsø; Stenberg, Thor Allan; Patel, Hitendra R.H.; Aarsæther, Erling Johan (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-09)
      Background - Open partial nephrectomy (OPN) has previously been considered the gold standard procedure for treatment of T1 localized renal tumors. After introduction of robot assisted partial nephrectomy (RAPN) as an alternative method to OPN, OPN was gradually abandoned at our department. The aim of the study was to retrospectively compare the results of patients treated with either OPN or RAPN for ...

      Pylkkö, Tuomas; Schneider, Yannik Karl Heinz; Rämä, Teppo; Andersen, Jeanette Hammer; Tammela, Päivi (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-30)
      A considerable number of antibacterial agents are derived from bacterial metabolites. Similarly, numerous known compounds that impede bacterial virulence stem from bacterial metabolites. Enteropathogenic Escherichia coli (EPEC) is a notable human pathogen causing intestinal infections, particularly affecting infant mortality in developing regions. These infections are characterized by microvilli ...

      Bullen, James; Nickel, Brooke; McCaffery, Kirsten; Wilt, Timothy J.; Smith, Jenna; Boroumand, Farzaneh; Parker, Lisa; Millar, Jeremy; Brodersen, John; Dahm, Philipp; Delahunt, Brett; Varma, Murali; Glasziou, Paul; Warden, Andrew; Diller, Lawrence; Billington, Larry; van Rensburg, Christo; Bell, Katy (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-09)
      Introduction - Many types of prostate cancer present minimal risk to a man’s lifespan or well-being, but existing terminology makes it difficult for men to distinguish these from high-risk prostate cancers. This study aims to explore whether using an alternative label for low-risk prostate cancer influences management choice and anxiety levels among Australian men and their partners.<p> <p>Methods ...
    • Sea ice mass balance during the MOSAiC drift experiment: Results from manual ice and snow thickness gauges

    • Characterization of Monocarboxylate Transporters in the Brain of the Hooded Seal (Cystophora cristata) Reveal Possible Biochemical Adaptation to Diving 

      Jensen, Sigrid Vold (Master thesis; Mastergradsoppgave, 2024-08-29)
      Diving mammals are perpetually required to manage low-oxygen conditions throughout their lives. The mammalian brain is an organ particularly vulnerable to low oxygen levels due to its high energy demands, which require steady aerobic ATP production. The brain of the deep- diving hooded seal (Cystophora cristata) demonstrates remarkable tolerance to hypoxia. Studies suggest that this brain hypoxia ...
    • Benthic Megafauna Biodiversity Associated to Vulnerable Marine Ecosystems in Norwegian waters 

      Garcia Cambeiro, Juan Manuel (Master thesis; Mastergradsoppgave, 2024-08-15)
      The biodiversity of benthos is influenced by habitat forming taxa defining Vulnerable Marine Ecosystems (VME). Such indicator taxa are used to identify and designate VME areas, but their numerical relation to benthic biodiversity is not known. In this thesis I address the relationship between abundance of VME indicator-taxa and megabenthos biodiversity in Norwegian waters. The main objectives were ...
