  • Buckling of scroll waves 

    Dierckx, H.; Verschelde, H.; Selsil, O.; Biktashev, V. N. (American Physical Society, 2012)
    A scroll wave in a sufficiently thin layer of an excitable medium with negative filament tension can be stable nevertheless due to filament rigidity. Above a certain critical thickness of the medium, such scroll wave will ...
  • The Build-up to Eruptive Solar Events Viewed as the Development of Chiral Systems 

    Martin, Sara F.; Panasenco, Olga; Berger, M.A.; Engvold, Oddbjorn; Lin, Yong; Pevtsov, Alexei A.; Srivastava, Nandita (Astronomical Society of the Pacific, 2012)
    When we examine the chirality or observed handedness of the chromospheric and coronal structures involved in the long-term build-up to eruptive events, we find that they evolve in very specific ways to form two and only ...
