    • Casimir friction between dense polarizable media 

      Høye, Johan Skule; Brevik, Iver Håkon (Peer reviewed; Journal article, 2013)
      The present paper—a continuation of our recent series of papers on Casimir friction for a pair of particles at low relative particle velocity—extends the analysis, so as to include dense media. The situation becomes, in ...

    • Fractal-Like Flow-Fields with Minimum Entropy Production for Polymer Electrolyte Membrane Fuel Cells 

      Kizilova, Nataliya; Sauermoser, Marco; Kjelstrup, Signe; Pollet, Bruno (Journal article; Peer reviewed, 2020)

    • General bulk-viscous solutions and estimates of bulk viscosity in the cosmic fluid 

      Normann, Ben David; Brevik, Iver Håkon (Journal article; Peer reviewed, 2016)
      We derive a general formalism for bulk viscous solutions of the energy-conservation equation for ρ(a,ζ) ρ(a,ζ) , both for a single-component and a multicomponent fluid in the Friedmann universe. For our purposes, these ...

    • High-dimensional separability for one-and few-shot learning 

      Gorban, Alexander N.; Grechuk, Bogdan; Mirkes, Evgeny M.; Stasenko, Sergey V.; Tyukin, Ivan Yurievich (Peer reviewed; Journal article, 2021)
      This work is driven by a practical question: corrections of Artificial Intelligence (AI) errors. These corrections should be quick and non-iterative. To solve this problem without modification of a legacy AI system, we ...

    • MyI-Net: Fully Automatic Detection and Quantification of Myocardial Infarction from Cardiovascular MRI Images 

      Wang, Shuihua; Abdelaty, Ahmed M. S. E. K.; Parke, Kelly; Arnold, Jayanth Ranjit; McCann, Gerry P.; Tyukin, Ivan Yurievich (Peer reviewed; Journal article, 2023)
      Myocardial infarction (MI) occurs when an artery supplying blood to the heart is abruptly occluded. The “gold standard” method for imaging MI is cardiovascular magnetic resonance imaging (MRI) with intravenously administered ...

    • Notes on Computational Uncertainties in Probabilistic Risk/Safety Assessment 

      Rauzy, Antoine (Journal article; Peer reviewed, 2018)
      In this article, we study computational uncertainties in probabilistic risk/safety assessment resulting from the computational complexity of calculations of risk indicators. We argue that the risk analyst faces the fundamental ...

    • Viscosity in modified gravity 

      Brevik, Iver Håkon (Journal article; Peer reviewed, 2012)
      A bulk viscosity is introduced in the formalism of modified gravity. It is shown that, based on a natural scaling law for the viscosity, a simple solution can be found for quantities such as the Hubble parameter and the ...

    • Viscosity-Induced Crossing of the Phantom Barrier 

      Brevik, Iver Håkon (Journal article; Peer reviewed, 2015)
      We show explicitly, by using astrophysical data plus reasonable assumptions for the bulk viscosity in the cosmic fluid, how the magnitude of this viscosity may be high enough to drive the fluid from its position in the ...
