    • Mapping the shape and dimension of three-dimensional Lagrangian coherent structures and invariant manifolds 

      Aksamit, Nikolas Olson (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-10)
      We introduce maps of Cauchy–Green strain tensor eigenvalues to barycentric coordinates to quantify and visualize the full geometry of three-dimensional deformation in stationary and non-stationary fluid flows. As a natural extension of Lagrangian coherent structure diagnostics, which provide separate scalar fields and a one-dimensional quantification of fluid deformation, our barycentric mapping ...
    • On Uniqueness of Submaximally Symmetric Vector Ordinary Differential Equations of C-Class 

      Kessy, Johnson Allen; The, Dennis (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-10)
      The fundamental invariants for vector ODEs of order ≥3 considered up to point transformations consist of generalized Wilczynski invariants and C-class invariants. An ODE of C-class is characterized by the vanishing of the former. For any fixed C-class invariant U , we give a local (point) classification for all submaximally symmetric ODEs of C-class with U≢0 and all remaining C-class invariants ...
    • Assessing ocean ensemble drift predictions by comparison with observed oil slicks 

      Martins de Aguiar, Victor Cesar; Röhrs, Johannes; Johansson, Malin; Eltoft, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-16)
      Geophysical models are cornerstone pieces in marine forecasting of floating objects and pollution, such as marine surface oil slicks. Trajectory forecasts of oil spills inherit the uncertainties from the underlying geophysical forcing. In this work we compare the forecast capabilities of an ocean ensemble prediction system (EPS) to those from a higher resolution deterministic model on ...
    • The making of the oral microbiome in Agta hunter-gatherers 

      Dobon, Begoña; Musciotto, Federico; Mira, Alex; Greenacre, Michael; Schlaepfer, Rodolph; Aguileta, Gabriela; Astete, Leonora H.; Ngales, Marilyn; Latora, Vito; Battiston, Federico; Vinicius, Lucio; Migliano, Andrea B.; Bertranpetit, Jaume (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-22)
      Ecological and genetic factors have influenced the composition of the human microbiome during our evolutionary history. We analysed the oral microbiota of the Agta, a hunter–gatherer population where some members have adopted an agricultural diet. We show that age is the strongest factor modulating the microbiome, probably through immunosenescence since we identified an increase in the number of ...

    • Tracing basal resource use across sea-ice, pelagic, and benthic habitats in the early Arctic spring food web with essential amino acid carbon isotopes 

      Vane, Kim; Cobain, Matthew R. D.; Trueman, Clive N.; Vonnahme, Tobias R.; Rokitta, Sebastian; Polunin, Nicholas V. C.; Flores, Hauke (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-09)
      A rapidly warming Arctic Ocean and associated sea-ice decline is resulting in changing sea-ice protist communities, affecting productivity of under-ice, pelagic, and benthic fauna. Quantifying such effects is hampered by a lack of biomarkers suitable for tracing specific basal resources (primary producers and microorganisms) through food webs. We investigate the potential of δ<sup>13</sup>C values ...
    • Isotopic turnover of polar cod (Boreogadus saida) muscle determined through a controlled feeding experiment 

      Ziegler, Amanda; Bluhm, Bodil; Renaud, Paul Eric; Jørgensen, Lis Lindal (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-30)
      Polar cod (Boreogadus saida) is an important trophic link within Arctic marine food webs and is likely to experience diet shifts in response to climate change. One important tool for assessing organism diet is bulk stable isotope analysis. However, key parameters necessary for interpreting the temporal context of stable isotope values are lacking, especially for Arctic species. This study provides ...
    • The challenge of dealing with non-AIDS comorbidities for people living with HIV: Perspectives and experiences of patients and healthcare providers 

      van Koeveringe, Julia Maria; Liaño Callahan, Elizabeth; George, Mala; Russo, Teklu Teshome; Seifu, Biruk; Spigt, Marcus (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-13)
      As the cohort of People Living with HIV (PLHIV) ages, so does the spectrum and burden of non-AIDS define HIV-associated conditions (NARC). PLHIV are likely to need different and increased healthcare services. It requires health systems to adapt to this disease trend and conform to a chronic care model, which respects the distinct needs of the ageing population. In this article, we explore the ...

      Harder, Christoffer Bugge; Hesling, Emily; Botnen, Synnøve Smebye; Lorberau, Kelsey; Dima, Bálint; von Bonsdorff-Salminen, Tea; Niskanen, Tuula; Jarvis, Susan G.; Ouimette, Andrew; Hester, Alison; Hobbie, Erik A.; Taylor, Andy F. S.; Kauserud, Håvard (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-15)
      Traditional strict separation of fungi into ecological niches as mutualist, parasite or saprotroph is increasingly called into question. Sequences of assumed saprotrophs have been amplified from plant root interiors, and several saprotrophic genera can invade and interact with host plants in laboratory growth experiments. However, it is uncertain if root invasion by saprotrophic fungi is a widespread ...
