Information Transmission Concept Based Model of Wave Propagation in Discrete Excitable Media
Nonlinear Analysis, 2004 A new information transmission concept based model of excitable media with continuous outputs of the model’s cells and variable excitation time is proposed. Continuous character of the outputs instigates infinitesimal inaccuracies in calculations.

Annual Review of Astronomy and Astrophysics, 2022 Spirals in galaxies have long been thought to be caused by gravitational instability in the stellar component of the disk, but discerning the precise mechanism had proved elusive. Tidal interactions, and perhaps bars, may provoke some spiral responses, but spirals in many galaxies must be self-excited.

THEMIS ground-space observations during the development of auroral spirals [PDF]
Annales Geophysicae, 2009 A simultaneous observation of an auroral spiral and its generator region in the near-Earth plasma sheet is rather unlikely. Here we present such observations using the THEMIS spacecraft as well as the THEMIS ground network of all-sky imagers and ...

Science, 2018 The timing was perfect. A few weeks after the experimental protocol that had served me for years inexplicably stopped working, my grad school adviser approached me about writing a review paper detailing the history of our field. I was feeling hopeless about my lab work.
