Transcranial photoacoustic tomography de-aberrated using boundary elements

K Sastry, Y Aborahama, Y Luo, Y Zhang… - … on Medical Imaging, 2025 - ieeexplore.ieee.org
Photoacoustic tomography holds tremendous potential for neuroimaging due to its functional
magnetic resonance imaging (fMRI)-like functional contrast and greater specificity, richer …

Boundary element methods for Helmholtz problems with weakly imposed boundary conditions

T Betcke, E Burman, MW Scroggs - SIAM Journal on Scientific Computing, 2022 - SIAM
We consider boundary element methods where the Calderón projector is used for the
system matrix and boundary conditions are weakly imposed using a particular variational …

Weak imposition of Signorini boundary conditions on the boundary element method

E Burman, S Frei, MW Scroggs - SIAM Journal on Numerical Analysis, 2020 - SIAM
We derive and analyze a boundary element formulation for boundary conditions involving
inequalities. In particular, we focus on Signorini contact conditions. The Calderón projector …

The numerical computation of Casimir energies and related spectral problems

X Sun - 2024 - discovery.ucl.ac.uk
Computing the Casimir force and energy between objects is a classical problem of quantum
theory going back to the 1940s. Since then, various approaches have been developed …
