师弟王延博士来组讨论,谈及Wen-Xu Wang等新近之作。 PRL 106, 154101 (2011) Predicting Catastrophes in Nonlinear Dynamical Systems by Compressive Sensing Abstract:An extremely challenging problem of significant interest is to predict catastrophes in advance of their occurrences. We presen ...
Front Reversals,Wave Traps, and Twisted Spirals in Periodically Forced Oscillatory Media Oliver Rudzick* and Alexander S. Mikhailov Abstract : A new kind of nonlinear nonequilibrium patterns—twisted spiral waves—is predicted for periodically forced oscillatory reaction-diffusion media. We sh ...
Breathing spiral waves in the chlorine dioxide–iodine–malonic acid reaction-diffusion system Igal Berenstein, Alberto P. Muuzuri, Lingfa Yang, Milos Dolnik, Anatol M. Zhabotinsky, and Irving R. Epstein Phys. Rev. E 78 , 025101 (2008) – Published August 11, 2008 Breat ...
Doppler instability of antispiral waves in discrete oscillatory reaction-diffusion media 2010 Chinese Phys. B 19 050513 Qian Yu(钱郁), Huang Xiao-Dong(黄晓东), Liao Xu-Hong(廖旭红), and Hu Gang(胡岗) This paper investigates antispiral wave breakup phenomena in coupled two-dimensional FitzH ...
http://pre.aps.org/abstract/PRE/v81/i6/e066202 Computation of the drift velocity of spiral waves using response functions Abstract: Rotating spiral waves are a form of self-organization observed in spatially extended systems of chysical,chemical, and biological nature. In the presence of a ...
非平常的动力系统分岔分析是我最近在查询Floquet理论的应用时找到的,浏览了这篇的introduction部分后,知道这个方面的工作虽然The dynamics of non-smooth systems is a relatively young research field,但也有不短的研究历史和不少的研究文献了。 我关心的是这些不同于平滑系统的分岔特点,对于斑图 ...
Abstract: Using an open-flow reactor periodically perturbed with light, we observe sub-harmonic frequency locking of the oscillatory Belousov-Zhabotinsky chemical reaction at one sixth the forcing frequency (6:1) over a region of the parameter space of forcing intensity and forcing frequency where ...
PRL 98, 034101 (2007) Abstract:The understanding of emergent collective phenomena in natural and social systems has driven the interest of scientists from different disciplines during decades. Among these phenomena, the synchronization of a set of interacting individuals or units has been intensivel ...
