  • Ringstad, Geir; Valnes, Lars Magnus; Dale, Anders; Pripp, Are Hugo; Vatnehol, Svein Are Sirirud; Emblem, Kyrre Eeg; Mardal, Kent-Andre; Eide, Per Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    To what extent does the subarachnoid cerebrospinal fluid (CSF) compartment communicate directly with the extravascular compartment of human brain tissue? Interconnection between the subarachnoid CSF compartment and brain ...
  • Tveito, Aslak; Jæger, Karoline Horgmo; Kuchta, Miroslav; Mardal, Kent-Andre; Rognes, Marie Elisabeth (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    In this paper, we study a mathematical model of cardiac tissue based on explicit representation of individual cells. In this EMI model, the extracellular (E) space, the cell membrane (M), and the intracellular (I) space ...
  • Lindstrøm, Erika Kristina; Ringstad, Geir; Mardal, Kent-Andre; Eide, Per Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The aim of the present study was to examine cerebrospinal fluid (CSF) volumetric net flow rate and direction at the cranio-cervical junction (CCJ) and cerebral aqueduct in individuals with idiopathic normal pressure ...
  • Ringstad, Geir; Lindstrøm, Erika Kristina; Vatnehol, Svein Are; Mardal, Kent-Andre; Emblem, Kyrre Eeg; Eide, Per Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Invasive monitoring of pulsatile intracranial pressure can accurately predict shunt response in patients with idiopathic normal pressure hydrocephalus, but may potentially cause complications such as bleeding and infection. ...
  • Haga, Per Thomas; Pizzichelli, Giulia; Mortensen, Mikael; Kuchta, Miroslav; Pahlavian, Soroush Heidari; Sinibaldi, Edoardo; Martin, Bryn A.; Mardal, Kent-Andre (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Intrathecal drug and gene vector delivery is a procedure to release a solute within the cerebrospinal fluid. This procedure is currently used in clinical practice and shows promise for treatment of several central nervous ...
  • Kuchta, Miroslav; Mardal, Kent-Andre; Mortensen, Mikael (Journal article / Tidsskriftartikkel / SubmittedVersion, 2019)
    The Neumann problem of linear elasticity is singular with a kernel formed by the rigid motions of the body. There are several tricks that are commonly used to obtain a nonsingular linear system. However, they often cause ...
  • Lee, Jeonghun J.; Mardal, Kent-Andre; Winther, Ragnar (Journal article / Tidsskriftartikkel / SubmittedVersion, 2016)
    Biot's consolidation model in poroelasticity has a number of applications in science, medicine, and engineering. The model depends on various parameters, and in practical applications these parameters range over several ...
  • Evju, Øyvind; Pozo, Jose M.; Frangi, Alejandro F.; Mardal, Kent-Andre (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Background: Using computational fluid dynamics (CFD) to compute the hemodynamics in cerebral aneurysms has received much attention in the last decade. The usability of these methods depends on the quality of the computations, ...
  • Funke, Simon Wolfgang; Nordaas, Magne; Evju, Øyvind; Alnæs, Martin; Mardal, Kent-Andre (Journal article / Tidsskriftartikkel / SubmittedVersion, 2019)
    Several cardiovascular diseases are caused from localised abnormal blood flow such as in the case of stenosis or aneurysms. Prevailing theories propose that the development is caused by abnormal wall shear stress in focused ...
  • Bærland, Trygve; Lee, Jeonghun J.; Mardal, Kent-Andre; Winther, Ragnar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    We discuss the construction of robust preconditioners for finite element approximations of Biot’s consolidation model in poroelasticity. More precisely, we study finite element methods based on generalizations of the ...
