We describe recent methodological progress and applications of electronic structure theory methods implemented in a numeric atom-centered orbital framework(FHI-aims).
Mathematical calculation of the texture in MR images demonstrates promise to detect subtle changes in tissue structure but is subject to pathological validation.Here we imaged 10 postmortem brain samp
S-transform is an effective time-frequency analysis technique that can provide simultaneous time and frequency distribution information similar to the wavelet transform.We introduce the ideas of wavel
This paper considers the optimization model with L2 and total variation regularization terms to approximate solutions to some linear inverse problems.The model is reformulated as a saddle-point proble
We propose the use of a constraint(indefinite)preconditioner for the iterative solution of the linear system arising from the finite element discretization of coupled Stokes-Darcy flow.
Finite element discretisation of the Dirichlet biharmonic problem by Bogner-Fox-Schmit(bicubic Hermite)elements leads to a symmetric positive definite coefficient matrix.
Krylov subspace recycling is useful for solving a sequence of slowly changing linear systems.It has been shown that recycled GMRES usually cannot be used in conjunction with shifted system techniques
The inverted device architecture of polymer solar cell(i-PSCs) is an attractive approach for its superior long-term stability compared to the initially implemented conventional device structures.
