coarse-grained sediments Ebullition-enhanced solute transport
2014/10/16
Pore-water exchange caused by ebullition of small oxygen bubbles produced by microalgae in the surface layer
of sand sediment at St. Joseph Bay (SJB), Gulf of Mexico, was contrasted with ebullition o...
Experimental study on coarse grain saltation dynamics in bedrock channels
Experimental study coarse grain saltation dynamics bedrock channels
2014/4/8
Saltation of bed load particles on bedrock surfaces is important for landscape evolution and bedrock incision in steep landscapes. However, few studies have investigated saltation in bedrock channels ...
Nonoverlapping Domain Decomposition Methods with Simplified Coarse Spaces for Solving Three-dimensional Elliptic Problems

2012/8/8
In this paper we propose a substructuring preconditioner for solving three-dimensional
elliptic equations with strongly discontinuous coe±cients. The new preconditioner
can be viewed as a variant of...

We utilize a coarse-grained directional dynamic bonding DNA model [C. Svaneborg, Comp. Phys. Comm. (In Press DOI:10.1016/j.cpc.2012.03.005)] to study DNA self-assembly and DNA computation. In our DNA ...
We show that the Kakimizu complex of minimal genus Seifert surfaces for a knot in the 3-sphere is quasi-isometric to a Euclidean integer lattice $\mathbb Z^n$ for some $n \geq 0$.
An equation-free approach to coarse-graining the dynamics of networks

2012/2/29
We propose and illustrate an approach to coarse-graining the dynamics of evolving networks (networks whose connectivity changes dynamically). The approach is based on the equation-free framework: shor...
On the Existence of a Self-Similar Coarse Graining of a Self-Similar Space

Abstract: A topological space homeomorphic to a self-similar space is demonstrated to be self-similar. There exists a self-similar space $S$ whose coarse graining is homeomorphic to $S$. The coarse gr...
Coarse-grained Simulations of Chemical Oscillation in Lattice Brusselator System
Chemical oscillation Coarse-grained Kinetic Monte Carlo
2012/4/5
The oscillation behavior of a two-dimension lattice-gas Brusselator model was investigated. We have adopted a coarse-grained kinetic Monte Carlo (CG-KMC) procedure, where m￡m microscopic lattice sites...
Describing the combinatorial structure of the tropical complex C of a tropical ma-troid polytope, we obtain a formula for the coarse types of the maximal cells of C. Due to the connection between trop...
Discretizations of continuum theories often do not preserve the gauge symmetry content. This occurs in particular for diffeomorphism symmetry in general relativity, which leads to severe difficulties ...

Recent work has hypothesized that tropical cyclones in the deep Atlantic and eastern Pacific basins develop from within the cyclonic Kelvin cat's eye of a tropical easterly wave critical layer located...

In previous work, a class of noninvertible topological dynamical systems $f: X \to X$ was introduced and studied; we called these {\em topologically coarse expanding conformal} systems. To such a sys...
