    • S-polarized light-sheets improve resolution and light-efficiency in oblique plane microscopy 

      Sommernes, Jon-Richard; Millett-Sikking, Alfred; Ströhl, Florian (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-12)
      Oblique plane microscopy (OPM) offers 3D optically sectioned imaging with high spatial- and temporal-resolution while enabling conventional sample mounting. The technique uses a concatenation of three microscopes, two for remote focusing and a tilted tertiary microscope, often including an immersion objective, to image an oblique sample plane. This design induces Fresnel reflections and a reduced ...
    • Managing the Transition Towards Zero-Emission Aviation: A Grounded Theory Approach to Change Management 

      Nelson, Stener Berg (Master thesis; Mastergradsoppgave, 2023-08-31)
      The planet is facing the prospect of irreversible climate change, and aviation is expected to contribute to a future zero-emission society. The Norwegian government, technical developers and aviation industry deem Norway as a suitable arena for developing, testing, and implementing zero-emission aviation technology.

    • BPI-GNN: Interpretable brain network-based psychiatric diagnosis and subtyping 

      Zheng, Kaizhong; Yu, Shujian; Chen, Liangjun; Dang, Lujuan; Chen, Badong (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-01)
      Converging evidence increasingly suggests that psychiatric disorders, such as major depressive disorder (MDD) and autism spectrum disorder (ASD), are not unitary diseases, but rather heterogeneous syndromes that involve diverse, co-occurring symptoms and divergent responses to treatment. This clinical heterogeneity has hindered the progress of precision diagnosis and treatment effectiveness in ...
    • Weichselian–Holocene glacial history of the Sjuøyane archipelago, northern Svalbard 

      Schomacker, Anders; Alexanderson, Helena; Farnsworth, Wesley Randall; Furze, Mark F.A.; Kjellman, Sofia Elisabeth; Kirchner, Nina; Erstorp, Elias Strandell; Noormets, Riko; Jomelli, Vincent; Ingólfsson, Ólafur (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-05)
      The Sjuøyane archipelago is the northernmost land area of Svalbard; thus, it provides a window to study the terrestrial glacial history and dynamics of the Svalbard–Barents Sea Ice Sheet and complement marine geological studies in the region. To reconstruct the glacial history of Sjuøyane, we describe coastal sedimentary sections in Quaternary sediments and constrain their chronology by radiocarbon ...

    • En verden i uro: hvordan kan vi styrke beredskapen mellom Norge og Finland? 

      Rustad, Siri Søbakken (Master thesis; Mastergradsoppgave, 2024-06-03)
      Den sikkerhetspolitiske situasjonen er i rask endring og fokus på samfunnssikkerhet og beredskap har kanskje aldri vært større. I 2023 la Totalberedskapskommisjonen frem sin rapport som understreker behovet for økt samarbeid i Norden. Rapporten viser til at vi må styrke samarbeidet for et bedre totalforsvar, samfunnssikkerhet og beredskap ved å jobbe tettere sammen på tvers av landegrensene. Dette ...

    • Barn og unges motivasjon for gjengdeltakelse – en litteraturstudie 

      Luneborg, Hanne (Master thesis; Mastergradsoppgave, 2024-05-31)
      Barn og unges deltakelse i kriminelle gjenger i Sverige har blitt et stadig økende problem, og grov vold og drap blant unge har nådd et rekordhøyt nivå. Barn og unge rekrutteres av kriminelle gjenger for å transportere, selge og oppbevare narkotika og våpen, delta i bedragerier og utføre vold. Gjengkriminalitet blant barn og unge er en voksende utfordring i flere områder i Sverige, og ytterligere ...
    • High-resolution imaging in acoustic microscopy using deep learning 

      Banerjee, Pragyan; Milind Akarte, Shivam; Kumar, Prakhar; Shamsuzzaman, Muhammad; Butola, Ankit; Agarwal, Krishna; Prasad, Dilip Kumar; Melandsø, Frank; Habib, Anowarul (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-18)
      Acoustic microscopy is a cutting-edge label-free imaging technology that allows us to see the surface and interior structure of industrial and biological materials. The acoustic image is created by focusing high-frequency acoustic waves on the object and then detecting reflected signals. On the other hand, the quality of the acoustic image's resolution is influenced by the signal-to-noise ratio, the ...

    • Combinatorics and semi-algebraic geometry of orbit spaces: Hyperbolic and stable polynomials, the degree principle and few inequalities defining orbit spaces 

      Schabert, Robin (Doctoral thesis; Doktorgradsavhandling, 2024-09-20)
      <p>Algebraic geometry studies the set of common zeros of a system of polynomials in one or several variables - most commonly over algebraically closed fields. Real algebraic geometry studies sets defined by a finite system of polynomial inequalities. <p>A starting point for modern real algebraic geometry can be traced back to Hilbert: In 1888, Hilbert showed the existence of nonnegative polynomials ...
    • Slicing orbit spaces: Geometry and combinatorics of hyperbolic and even-hyperbolic slices 

      Lien, Arne (Doctoral thesis; Doktorgradsavhandling, 2024-09-18)
      Motivated by a connection to Timofte’s degree and halfdegree principle we study canonical hyperbolic slices, that is, sets of univariate hyperbolic polynomials that share the same first few coefficients. We study the geometric and combinatorial properties of a natural stratification of these slices and use these properties to improve upon the degree principle. Amongst the geometric properties we ...
