It is shown that under the homogeneous Neumann boundary conditions the system possesses a unique global classical solution which is bounded whenever both $\int_\Omega u_0dx$ and $\int_\Omega w_0dx$ are appropriately small. In particular, we extend the recent results obtained by Tao and Winkler (2015, Disc. Cont. Dyn. Syst. B) to the fully parabolic case, i.e., the case of $\tau=1$. ]]> Xie Li and Yilong Wang Fri, 1 Sep 2017 20:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14010 Adaptive methods for stochastic differential equations via natural embeddings and rejection sampling with memory http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14010 Christopher Rackauckas and Qing Nie Fri, 1 Sep 2017 20:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14011 A diffusive SIS epidemic model incorporating the media coverage impact in the heterogeneous environment http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14011 Jing Ge, Ling Lin and Lai Zhang Fri, 1 Sep 2017 20:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14012 Emergence of large population densities despite logistic growth restrictions in fully parabolic chemotaxis systems http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14012 0,\\ v_t=\Delta v -v+u, \qquad & x\in\Omega, \ t>0, \end{aligned} \right. \end{equation*} in a ball $\Omega\subset\mathbb{R}^n$, $n\ge 3$, with parameters $\chi>0, \rho\ge 0$ and $\mu>0$.
    By means of an argument based on a conditional quasi-energy inequality, it is firstly shown that if $\chi=1$ is fixed, then for any given $K>0$ and $T>0$ one can find radially symmetric initial data, possibly depending on $K$ and $T$, such that for arbitrary $\mu\in (0,1)$ the corresponding local-in-time classical solution $(u,v)$ satisfies \begin{equation*} \begin{aligned} u(x,t) > \frac{K}{\mu} \end{aligned} \end{equation*} with some $x\in\Omega$ and $t\in (0,T)$; in fact, this growth phenomenon is actually identified as being generic in the sense that the set of all initial data having this property is dense in the set of all suitably regular radial initial data in a certain topology.
    Secondly, turning a focus on possible effects of large chemotactic sensitivities, on the basis of the above it is shown that when $\rho\ge 0$ and $\mu>0$ are fixed, then for all $L>0, T>0$ and $\chi>\mu$ one can fix radial initial data $(u_{0,\chi}, v_{0,\chi})$ which decay in $L^\infty(\Omega)\times W^{1,\infty}(\Omega)$ as $\chi\to\infty$, and which are such that for the respective solution $(u_\chi,v_\chi)$ there exist $x\in\Omega$ and $t\in (0,T)$ fulfilling \begin{equation*} \begin{aligned} u_\chi(x,t) > L. \end{aligned} \end{equation*} ]]>

This system accounts for degenerate diffusion at the population density $n=b=0$ and $b=1$ modeling the growth of certain bacteria colony with volume filling. The existence of the finite traveling wave solutions is proven which provides partial answers to the spatial patterns of the colony. In order to overcome the difficulty of traditional phase plane analysis on higher dimension, we use Schauder fixed point theorem and shooting arguments in our paper. ]]> Lianzhang Bao and Wenjie Gao Fri, 1 Sep 2017 20:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14092 New convergence analysis for assumed stress hybrid quadrilateral finite element method http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14092 Binjie Li, Xiaoping Xie and Shiquan Zhang Fri, 1 Sep 2017 20:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14093 The stabilized semi-implicit finite element method for the surface Allen-Cahn equation http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14093 Xufeng Xiao, Xinlong Feng and Jinyun Yuan Fri, 1 Sep 2017 20:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14094 Asymptotic behaviour of an age and infection age structured model for the propagation of fungal diseases in plants http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=14094 1$.

For $c > c^*$, we will further show that the traveling front is globally asymptotic stable and is unique up to translation. If we applied to some differential equations or integro-differential equations, our results recover and/or complement a number of existing ones. ]]> Hongmei Cheng and Rong Yuan Fri, 1 Sep 2017 20:00:00 GMT
