Discontinuous modelling of crack propagation in a gradient-enhanced continuum [PDF]
A numerical model for the description of the combined continuous/discontinuous failure in a regularised strain-softening continuum is proposed. The continuum is regularised through the introduction of gradient terms into the constitutive equations.

Comparing macroscopic continuum models for rarefied gas dynamics : a new test method [PDF]
We propose a new test method for investigating which macroscopic continuum models, among the many existing models, give the best description of rarefied gas flows over a range of Knudsen numbers.

Control and maintenance of mammalian cell size
Background Conlon and Raff propose that mammalian cells grow linearly during the division cycle. According to Conlon and Raff, cells growing linearly do not need a size checkpoint to maintain a constant distribution of cell sizes.

Numerical simulation of aerosol oscillations in a narrow closed resonator [PDF]
This work is devoted to the numerical simulation of gas suspension oscillations in an acoustic resonator. The mathematical model utilizes a continuum technique for simulating the dynamics of multiphase media in Euler coordinates, accounting for the ...

Atomistic-to-continuum coupling approximation of a one-dimensional toy model for density functional theory [PDF]
We consider an atomistic model defined through an interaction field satisfying a variational principle and which can therefore be considered a toy model of (orbital-free) density functional theory.

Effects of Quartic Wave-Vectors on Continuum Model of Phosphorene
Phosphorene is themonolayer structures of black phosphorous. Its low-energy physics can bedescribed by continuum model in the scheme of k∙p theory. Validity of energyrange for this model can be improved by extra terms as trigonal warp effect ingraphene ...

Wavelet formulation of the polarizable continuum model. II. Use of piecewise bilinear boundary elements [PDF]
The simplicity of dielectric continuum models has made them a standard tool in almost any Quantum Chemistry (QC) package. Despite being intuitive from a physical point of view, the actual electrostatic problem at the cavity boundary is challenging: the ...

A priori error analysis of two force-based atomistic/continuum models of a periodic chain [PDF]
The force-based quasicontinuum (QCF) approximation is a non-conservative atomistic/continuum hybrid model for the simulation of defects in crystals. We present an a priori error analysis of the QCF method, applied to a one-dimensional periodic chain ...
