      Kurkela, Aleksi; Mazeliauskas, Aleksas; Paquet, Jean-Francois; Schlichting, Sören; Teaney, Derek (Peer reviewed; Journal article, 2019-03)
      High-energy nuclear collisions produce a nonequilibrium plasma of quarks and gluons which thermalizes and exhibits hydrodynamic flow. There are currently no practical frameworks to connect the early particle production in ...

      Evje, Steinar; Winkler, Michael (Peer reviewed; Journal article, 2020-04)
      Recent experimental work has revealed that interstitial fluid flow can mobilize two types of tumor cell migration mechanisms. One is a chemotactic-driven mechanism where chemokine (chemical component) bounded to the ...
