      Alza, Lía; Nager, Mireia; Visa, Anna; Cantí, Carles; Herreros, Judit (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-27)
      Focal adhesion kinase (FAK) is a central component of focal adhesions that regulate cancer cell proliferation and migration. Here, we studied the effects of FAK inhibition in glioblastoma (GBM), a fast growing brain tumor that has a poor prognosis. Treating GBM cells with the FAK inhibitor PF-573228 induced a proliferative arrest and increased cell size. PF-573228 also reduced the growth of GBM ...
    • Niche separation between two dominant crustacean predators in European estuarine soft-bottom habitats 

      Siegenthaler, Andjin; Wangensteen, Owen S.; Benvenuto, Chiara; Lollobrigidi, Riccardo; Mariani, Stefano (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-05)
      Epibenthic predators in estuarine shallow soft-bottom environments are generally considered to have broad ecological niches with a wide overlap. This allows them to cope with abundant but highly variable prey communities. The assessment of trophic relationships in shallow soft-bottom habitats is, however, challenging and often complicated by the bias and low resolution of the analytical tools available ...

      Alemán Bañón, José; Miller, David; Rothman, Jason (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-10)
      We used event-related potentials to investigate how markedness impacts person agreement in English-speaking learners of L2-Spanish. Markedness was examined by probing agreement with both first-person (marked) and third-person (unmarked) subjects. Agreement was manipulated by crossing first-person subjects with third-person verbs and vice-versa. Native speakers showed a P600 for both errors, larger ...
    • Decomposing the Prediction Problem; Autonomous Navigation by neoRL Agents 

      Leikanger, Per Roald (Journal article; Tidsskriftartikkel, 2021-07-19)
      Navigating the world is a fundamental ability for any living entity. Accomplishing the same degree of freedom in technology has proven to be difficult. The brain is the only known mechanism capable of voluntary navigation, making neuroscience our best source of inspiration toward autonomy. Assuming that state representation is key, we explore the difference in how the brain and the machine represent ...

      Valegård, Karin; Andralojc, P. John; Haslam, Richard P.; Pearce, F. Grant; Eriksen, Gunilla Kristina; Madgwick, Pippa J.; Kristoffersen, Anne Karin; van Lun, Michiel; Klein, Uwe; Eilertsen, Hans Christian; Parry, Martin A.J.; Andersson, Inger (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-20)
      The catalytic performance of the major CO<sub>2</sub>-assimilating enzyme, ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), restricts photosynthetic productivity. Natural diversity in the catalytic properties of Rubisco indicates possibilities for improvement. Oceanic phytoplankton contain some of the most efficient Rubisco enzymes, and diatoms in particular are responsible for a significant ...
    • Árran - levende historier i landskapet 

      Sommerseth, Ingrid (Journal article; Tidsskriftartikkel, 2006)
      Langs de gamle flytteveiene, fra innlandet over kjølen og ut til kysten, finner vi de samiske árran – ildstedene. De ligger der som perler på en snor, og knytter bånd mellom øst og vest. Árran ligger på boplassene i furuskogen, i tregrensen, på høyfjellet og ved havet, steder valgt ut for hver årstid. Studier av ulike árran er kilder til forståelse av tidligere generasjoners liv og virke. Ennå ...
