Local Tomography in Electron Microscopy
We present a new local tomographic algorithm applicable to electron microscope tomography. Our algorithm applies to the standard data acquisition method, single-axis tilting, as we...

Partially Reflected Diffusion
The radiation (reactive or Robin) boundary condition for the diffusion equation is widely used in chemical and biological applications to express reactive boundaries. The underlyin...

Ostwald Ripening in Thin Film Equations
Fourth order thin film equations can have late stage dynamics that arise in a fashion analogous to the classical Cahn Hilliard equation. Profound differences arise however, both b...

Effective Transport Equations and Enhanced Backscattering in Random Waveguides
In this paper we derive a general system of transport equations for the moments of reflected and transmitted mode amplitudes in a randomly perturbed waveguide, in a regime where ba...

Absolute Stability and Complete Synchronization in a Class of Neural Fields Models
Neural fields are an interesting option for modelling macroscopic parts of the cortex involving several populations of neurons, like cortical areas. Two classes of neural field equ...

Statistics of Polarization-Mode Dispersion Emulators with Unequal Sections
We study two models for the generation of polarization-mode dispersion (PMD) with unequal, fixed-length sections: an isotropic model, in which the orientations of all the sectional...

Mutually Exclusive Spiky Pattern and Segmentation Modeled by the Five-Component Meinhardt--Gierer System
We consider the five-component Meinhardt-Gierer model for mutually exclusive patterns and segmentation which was proposed in [11]. We prove rigorous results on the existence and st...

Recursive Dispersion Relations in One-Dimensional Periodic Elastic Media
A frequency bandgap is a range of wave frequencies that are prohibited from passing through a medium. The dispersion relation, which links the frequency to the wave number, enables...

A Thermal Elastic Model for Directional Crystal Growth with Weak Anisotropy
In this paper we present a semi-analytical thermal stress solution for directional growth of type III-V compounds with small lateral heat flux and weak anisotropy. Both geometric a...

A Level Set Approach to Anisotropic Surface Evolution with Free Adatoms
We variationally derive a thermodynamically consistent model for surface evolution under the influence of free adatoms. The resulting system of nonlinear partial differential equat...
