    • Inherent Chirality and Stereoisomerism in Metallocorrole Sandwich Compounds 

      Torstensen, Kristian (Master thesis; Mastergradsoppgave, 2024-01-07)
      In this thesis, I have presented my findings on stereoisomerism in eight-coordinate metallobiscorrole sandwich compounds. Metallobiscorroles were first synthesized in our laboratory about eight years ago and, although they were fully structurally characterized with X-ray crystallography, their crowded 1H NMR spectra essentially defied assignment. My master’s thesis project began with the task to ...
    • Tree models for assessing covariate-dependent method agreement with an application to physical activity measurements 

      Karapetyan, Siranush; Zeileis, Achim; Henriksen, André; Hapfelmeier, Alexander (Journal article; Tidsskriftartikkel; Peer reviewed, 2025-01-03)
      Method comparison studies assess agreement between different measurement methods. In the present work, we are interested in comparing physical activity measurements using two different accelerometers. However, a potential issue arises with the popular Bland–Altman analysis, as it assumes that differences between measurements are identically distributed across all observational units. In the case ...

    • Projections of precipitation and temperatures in Greenland and the impact of spatially uniform anomalies on the evolution of the ice sheet 

      Bochow, Nils; Poltronieri, Anna; Boers, Niklas (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-12)
      Simulations of the Greenland ice sheet (GrIS) at millennial timescales and beyond often assume spatially and temporally uniform temperature anomalies and precipitation sensitivities over these timescales or rely on simple parameterisation schemes for the precipitation rates. However, there is no a priori reason to expect spatially and temporally uniform sensitivities across the whole GrIS. Precipitation ...
