    • Real-Time Outdoor Localization Using Radio Maps: A Deep Learning Approach 

      Yapar, Cagkan; Levie, Ron; Kutyniok, Gitta Astrid Hildegard; Caire, Giuseppe (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-10)
      Global Navigation Satellite Systems typically perform poorly in urban environments, where the likelihood of line-of-sight conditions between devices and satellites is low. Therefore, alternative location methods are required to achieve good accuracy. We present LocUNet: A convolutional, end-to-end trained neural network (NN) for the localization task, which is able to estimate the position of a user ...
    • Improving Quality of ICD-10 (International Statistical Classification of Diseases, Tenth Revision) Coding Using AI: Protocol for a Crossover Randomized Controlled Trial

      Background: Computer-assisted clinical coding (CAC) tools are designed to help clinical coders assign standardized codes, such as the ICD-10 (International Statistical Classification of Diseases, Tenth Revision), to clinical texts, such as discharge summaries. Maintaining the integrity of these standardized codes is important both for the functioning of health systems and for ensuring data used ...
    • New insights from an eight-year study on per- and polyfluoroalkyl substances in an urban terrestrial ecosystem 

      Heimstad, Eldbjørg Sofie; Nygård, Torgeir; Moe, Børge; Herzke, Dorte (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-06)
      Per- and polyfluoroalkyl substances (PFAS) were analysed in a high number of terrestrial samples of soil, earthworm, bird eggs and liver from red fox and brown rat in an urban area in Norway from 2013 to 2020. PFOS and the long chain PFCAs were the most dominating compounds in all samples, proving their ubiquitous distribution. Other less studied compounds such as 6:2 FTS were first and foremost ...

    • Ofret Nansen vitenskapen for freden? 

      Jølle, Harald Dag (Chapter; Bokkapittel, 2023)
      Da Fridtjof Nansen døde i 1930, skrev Nordahl Grieg hjem til sin bror Harald Grieg: «For et eventyrlig liv som er forbi, det var jo ikke én stor mand som døde, det var ti». Nansens brede virke, hans mange evner, hans tilstedeværelse i store hendelser gir alt et voldsomt inntrykk – og har gitt ham mange merkelapper: vitenskapsmann, polfarer, kunstner, diplomat, filantrop, for å nevne noen. <p> <p>Det ...
    • Learning Analytics Based on Streamed Log Data from a Course in Logic 

      Øhrstrøm, Peter; Thorvaldsen, Steinar; Jakobsen, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-01)
      This paper describes the analysis of streamed log data generated from the use of two specific e-learning tools in the context of a basic logic course taught and evaluated at Aalborg University, Denmark, during the period from September 2022 to January 2023.

    • Advances in the expression and purification of human PARP1: A user-friendly protocol 

      Conceição, Carlota J.F.; Salgueiro, Bruno A.; Ribeiro, Paulo A.; Raposo, Maria; Moe, Elin (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-05)
      The PARP1 (Poly (ADP-ribose) polymerase 1) enzyme is essential for single and double-strand break repair in humans. Alterations affecting PARP1 activity have severe consequences for human health and are associated with pathologies like cancer, and metabolic and neurodegenerative disorders. Here, we have developed a fast and easy procedure for the expression and purification of PARP1. Biologically ...

    • DFT benchmarking for adsorption energy in wastewater treatment 

      Malloum, Alhadji; Conradie, Jeanet (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-31)
      Despite its potential importance, the computational chemistry of adsorption processes for wastewater treatment has received negligible attention. Exploring the literature shows several limitations in applying quantum chemistry to study adsorption processes in wastewater treatment. The choice of suitable functionals of density functional theory (DFT) is one of the critical limits of the current ...

      We present an implementation of a damped response framework for calculating resonant inelastic X-ray scattering (RIXS) at the equation-of-motion coupled-cluster singles and doubles (CCSD) and second-order approximate coupled-cluster singles and doubles (CC2) levels of theory in the open-source program eT. This framework lays the foundation for future extension to higher excitation methods (notably, ...
    • Exploring Earthly relations through curiography 

      Valtonen, Anu; Salmela, Tarja (Chapter; Bokkapittel, 2023-01-24)
      Recognizing that humans inhabit Earth with multiple others and that humans have worsened opportunities for life on Earth calls for a reassessment of the research practices through which the world is explored. The development of more-than-human methodologies is underway, as reflected in the emergence of more-than-human or multispecies ethnographies. However, leaning on ethnography as a methodological ...

    • Hva slags medisinsk behandling fikk Fruen fra Havet? 

      Bramness, Jørgen Gustav (Journal article; Tidsskriftartikkel; Peer reviewed, 2023)
      Fruen fra Havet handler om Ellida Wangels psykiske krise og dens løsning. Hennes mann, legen Johannes Wangel, framstår som bekymret og omsorgsfull. Det antydes at han gir henne medisiner, men det nevnes ikke hvilke. Mange har ment at Ibsen i stykket foregriper Freuds «snakkekur» med flere år. I denne artikkelen utforsker jeg de psykiske problemene Ellida har, hvilke legemidler det kunne være snakk ...
    • Northern Svalbard Composite Tectono-Sedimentary Element 

      Smelror, Morten; Olaussen, Snorre; Dumais, Marie-Andrée; Grundvåg, Sten-Andreas; Abay, Tesfamariam Berhane (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-11)
      The Northern Svalbard Composite Tectono-Sedimentary Element (CTSE) comprises Proterozoic, Early Paleozoic, and Devonian sedimentary rocks preserved in northern Svalbard and on the adjacent shelf margin. Here, the sedimentary strata of the CTSE are preserved between complexes of metamorphic and crystalline basement rocks. The Northern Svalbard CTSE covers four main tectonostratigraphic elements: ...
    • Matroid Stratifications of Hypergraph Varieties, Their Realization Spaces, and Discrete Conditional Independence Models 

      Clarke, Oliver; Grace, Kevin; Mohammadi, Fatemeh; Motwani, Harshit J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-01)
      We study varieties associated to hypergraphs from the point of view of projective geometry and matroid theory. We describe their decompositions into matroid varieties, which may be reducible and can have arbitrary singularities by the Mnëv–Sturmfels universality theorem. We focus on various families of hypergraph varieties for which we explicitly compute an irredundant irreducible decomposition. Our ...
    • Characteristics of music therapy with beneficial impacts on agitation in dementia 

      Kristiansen, Frode Aass; Stige, Brynjulf; Helle-Valle, Anna (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-01)
      Several reviews in recent years have reported evidence of the effect of music on the serious problem of agitation in dementia. Some reviews draw different conclusions, however, which actualizes the need for studies that examine characteristics of music therapy with beneficial impacts on agitation. In an instrumental case study, documented through qualitative interviews, recordings of group meetings, ...
    • Deep Optical Coding Design in Computational Imaging: A data-driven framework 

      Arguello, Henry; Bacca, Jorge; Kariyawasam, Hasindu; Vargas, Edwin; Marquez, Miguel; Hettiarachchi, Ramith; Garcia, Hans; Herath, Kithmini; Haputhanthri, Udith; Ahluwalia, Balpreet Singh; So, Peter; Wadduwage, Dushan N.; Edussooriya, Chamira U.S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-27)
      Computational optical imaging (COI) systems leverage optical coding elements (CEs) in their setups to encode a high-dimensional scene in a single or in multiple snapshots and decode it by using computational algorithms. The performance of COI systems highly depends on the design of its main components: the CE pattern and the computational method used to perform a given task. Conventional approaches ...
