Formal asymptotic limit of a diffuse-interface tumor-growth model (2015)
Journal Article

We consider a diffuse-interface tumor-growth model which has the form of a phase-field system. We characterize the singular limit of this problem. More precisely, we formally prove that as the coefficient of the reaction term tends to infinity, the s... Read More about Formal asymptotic limit of a diffuse-interface tumor-growth model.

Decay of bound states in a sine-Gordon equation with double well potentials (2015)
Journal Article

We consider a spatially inhomogeneous sine-Gordon equation with a double-well potential, describing long Josephson junctions with phase-shifts. We discuss the interactions of symmetric and antisymmetric bound states in the system. Using a multiple sc...

Bayesian registration of functions and curves (2015)
Journal Article
Cheng, W., Dryden, I. L., & Huang, X. (2015). Bayesian registration of functions and curves. Bayesian Analysis, 2015, https://doi.org/10.1214/15-BA957

Bayesian analysis of functions and curves is considered, where warping and other geometrical transformations are often required for meaningful comparisons. The functions and curves of interest are represented using the recently introduced square root... Read More about Bayesian registration of functions and curves.

Goal-oriented a posteriori error estimation for the travel time functional in porous media flows (2015)
Journal Article

In this article we consider the a posteriori error estimation and adaptive mesh refinement for the numerical approximation of the travel time functional arising in porous media flows. The key application of this work is in the safety assessment of ra... Read More about Goal-oriented a posteriori error estimation for the travel time functional in porous media flows.

A diffusion process associated with Fréchet means (2015)
Journal Article
Le, H. (2015). A diffusion process associated with Fréchet means. Annals of Applied Probability, 25(6), https://doi.org/10.1214/14-AAP1066

This paper studies rescaled images, under exp−1μ, of the sample Fréchet means of i.i.d. random variables {Xk|k≥1} with Fréchet mean μ on a Rie-mannian manifold. We show that, with appropriate scaling, these images converge weakly to a diffusion proce... Read More about A diffusion process associated with Fréchet means.

By defining a multiplication on a direct sum of n copies of a given cyclic division algebra, we obtain new unital non-associative algebras. We employ their left multiplication to construct rate-n and rate-2 fully diverse fast ML-decodable space-time... Read More about Fast-decodable MIDO codes from non-associative algebras.
