* News that this year's BBC Sports Personality of the Year will be broadcast live from the studios of MediaCityUK, prompted some excitable reaction in some quarters because only a limited number of places will be available for the public for the December 22 bash.
Chinese swimmer Fu Yuanhui's excitable reaction to her bronze medal in Rio went viral, leading many to call her "the most loveable athlete at the Rio Olympics". During the Games, she was praised by women's groups for acknowledging her menstrual period on air, normally a taboo subject in Chinese society.
The work by Goldstein [12, 13] and Muratov [14] on pattern formation in two-dimensional excitable reaction-diffusion systems is especially relevant in this context, as both authors have developed effective descriptions of interface dynamics in terms of non-local interactions.
Contrary to some excitable first reactions, Russia's ability to crush the minuscule Georgian army does not make it a superpower, and its aggression in the Caucasus need not mark the start of a new cold war.
This chemical verification of previous theoretical results brings closer the possibility of utilising this phenomenon for implementing collision-based gates, signal tuning and programming of collision-based computers based upon excitable chemical reactions.
This wave fragment like morphology is qualitatively similar to fragments of excitation which can exist in the sub-excitable BZ reaction.
While spiral waves can occur in systems with excitable and oscillatory reaction dynamics [ 22, 23] Turing patterns typically emerge in activator-inhibitor systems with long range inhibition [ 24, 25].
The two bifurcations at σ = 0 and σ = 1 are generic in the sense that they apply to excitable media based on reaction-diffusion mechanisms irrespective of the particular model.
If much of what has been said into stump mics during the past few days has been unpleasant and over-excitable, then the reaction to Jonathan Trott's departure from this Ashes tour with a stress-related illness has been thankfully restrained and sympathetic.
We describe this process for a molecular computing architecture that makes use of excitable lipid-coated droplets of Belousov Zhabotinsky reaction medium as its active processing components.
