Hamiltonian analysis of subcritical stochastic epidemic dynamics [PDF]
, 2017 We extend a technique of approximation of the long-term behavior of a supercritical stochastic epidemic model, using the WKB approximation and a Hamiltonian phase space, to the subcritical case.

Distribution limit of jet flow in the same and dissimilar phases of ambient fluid [PDF]
علوم و مهندسی آبیاری, 2016 In this article we studied the distribution limits of jet injection in the same phase and dissimilar phase ambient. To achieve the proposes of this research a physical model was set upped consist of experimental flume and related accessories, circular ...

Reynolds stresses and mean fields generated by pure waves: applications to shear flows and convection in a rotating shell [PDF]
, 2008 A general reformulation of the Reynolds stresses created by two-dimensional waves breaking a translational or a rotational invariance is described. This reformulation emphasizes the importance of a geometrical factor: the slope of the separatrices of the

Scattering of gravity waves in subcritical flows over an obstacle
, 2016 We numerically study the scattering coefficients of linear water waves on stationary flows above a localized obstacle. We compare the scattering on trans- and subcritical flows, and then focus on the latter which have been used in recent analog gravity ...

Metastability of a granular surface in a spinning bucket
, 1998 The surface shape of a spinning bucket of granular material is studied using a continuum model of surface flow developed by Bouchaud et al. and Mehta et al. An experimentally observed central subcritical region is reproduced by the model. The subcritical

Stability of earthquake clustering models:Criticality and branching ratios [PDF]
, 2013 We study the stability conditions of a class of branching processes prominent in the analysis and modeling of seismicity. This class includes the epidemic-type aftershock sequence (ETAS) model as a special case, but more generally comprises models in ...

, 2015 We reexamine the scattering coefficients of shallow water waves blocked by a stationary counter current over an obstacle. By considering series of background flows, we show that the most relevant parameter is $F_{\rm max}$, the maximal value of the ratio

Neuronal avalanches of a self-organized neural network with active-neuron-dominant structure [PDF]
, 2012 Neuronal avalanche is a spontaneous neuronal activity which obeys a power-law distribution of population event sizes with an exponent of -3/2. It has been observed in the superficial layers of cortex both \emph{in vivo} and \emph{in vitro}. In this paper
