چکیده
In this paper we focus on attraction-repulsion chemotaxis model with consumed signals $\begin{equation}\label{problem_abstract}\tag{$\Diamond$}\begin{cases}u_t = \Delta u - \chi \nabla \cdot (u v)+\xi w) & \text{ in }~~ \Omega \times (0, T_{max}), \\v_t v- uv \\w_t w- uw \end{cases}\end{equation}$ formulated a bounded and smooth domain $ of {\mathbb R}^n $, n\geq 2 for some positive real numbers \chi, \xi {T_{max}}\in \infty] $. Once equipped appropriately initial distributions u(x, 0) u_0(x)\geq 0 v(x, v_0(x)\geq w(x, w_0(x)\geq as well Neumann boundary conditions, establish sufficient assumptions its data yielding global classical solutions; these are functions u, v w zero normal derivative \partial \Omega\times {T_{max}}) satisfying pointwise the equations problem $\Diamond$ {T_{max}} \infty This is proved any such data, whenever belong to open intervals, depending respectively \|v_0\|_{L^{\infty}(\Omega)} \|w_0\|_{L^{\infty}(\Omega)} Finally, illustrate aspects dynamics present within system by means numerical simulations.

Classical solutions and steady states of an attraction-repulsion chemotaxis in one dimension.
We establish the existence of global classical solutions and non-trivial steady states of a one-dimensional attraction-repulsion chemotaxis model subject to the Neumann boundary conditions. The results are derived based on the method of energy estimates and the phase plane analysis.

Repulsion and Attraction with Sema3D
Calcium entry into the dendritic spines of excitatory neurons is important for many forms of synaptic plasticity. In this issue, Hoogland and Saggau continue efforts to inventory the calcium channels that function in dendritic spines. They evoked backpropagating action potentials at the soma of CA1 neurons in rat hippocampal slices and recorded calcium transients in basal dendrites and spines u...
متن کاملA Model of Lexical Attraction and Repulsion
This paper introduces new methods based on exponential families for modeling the correlations between words in text and speech. While previous work assumed the effects of word co-occurrence statistics to be constant over a window of several hundred words, we show that their influence is nonstationary on a much smaller time scale. Empirical data drawn from English and Japanese text, as well as c...
متن کاملBoundedness in a Three-dimensional Attraction-repulsion Chemotaxis System with Nonlinear Diffusion and Logistic Source
This article concerns the attraction-repulsion chemotaxis system with nonlinear diffusion and logistic source, ut = ∇ · ((u+ 1)m−1∇u)−∇ · (χu∇v) +∇ · (ξu∇w) + ru− μu , x ∈ Ω, t > 0, vt = ∆v + αu− βv, x ∈ Ω, t > 0, wt = ∆w + γu− δw, x ∈ Ω, t > 0 under Neumann boundary conditions in a bounded domain Ω ⊂ R3 with smooth boundary. We show that if the diffusion is strong enough or the logistic dampen...
