A C0 Nonconforming Virtual Element Method for the Kirchhoff Plate Obstacle Problem
This paper investigates a novel C0 nonconforming virtual element method (VEM) for solving the Kirchhoff plate obstacle problem, which is described by a fourth-order variational inequality (VI) of the first kind.

A Simultaneous Stacking and Deblending Algorithm for Astronomical Images
Stacking analysis is a means of detecting faint sources using a priori position information to estimate an aggregate signal from individually undetected objects. Confusion severely limits the effectiveness of stacking in deep surveys with limited angular

Analysis of Adjoint Error Correction for Superconvergent Functional Estimates [PDF]
Earlier work introduced the notion of adjoint error correction for obtaining superconvergent estimates of functional outputs from approximate PDE solutions. This idea is based on a posteriori error analysis suggesting that the leading order error term in

A Priori Error Estimates for Some Discontinuous Galerkin Immersed Finite Element Methods [PDF]
In this paper, we derive a priori error estimates for a class of interior penalty discontinuous Galerkin (DG) methods using immersed finite element (IFE) functions for a classic second-order elliptic interface problem. The error estimation shows that these methods can converge optimally in a mesh-dependent energy norm.
