Accurate and Efficient Data‐Driven Partitioned Scheme for Coupled Heterogeneous Numerical Models
Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.ABSTRACT Heterogeneous numerical models (HNMs) combine conventional discretization modules such as finite elements with nonconventional data‐driven and reduced‐order modules. HNMs can improve computational efficiency and enable simulations of multi‐physics systems in which one or more constituent components lack first‐principles descriptions and must ...

Protein Science, Volume 35, Issue 9, September 2026.Abstract Cryo‐electron tomography (cryo‐ET) enables structural characterization of biomolecules under near‐native conditions. Existing approaches for interpreting the resulting three‐dimensional volumes are computationally expensive and have difficulty interpreting density associated with small proteins/complexes.

The Schur-Convexity of the Generalized Muirhead-Heronian Means [PDF]
, 2014 We give a unified generalization of the generalized Muirhead means and the generalized Heronian means involving three parameters. The Schur-convexity of the generalized Muirhead-Heronian means is investigated.

Solution of RE Models with Anticipated Shocks and Optimal Policy [PDF]
The purpose of this paper is to solve linear dynamic rational expectations models with anticipated shocks by using the generalized Schur decomposition method. We also determine the optimal unrestricted and restricted policy responses to temporary as well

Schur Complement Trick for Positive Semi-definite Energies [PDF]
, 2014 The Schur complement trick appears sporadically in numerical optimization methods [Schur 1917; Cottle 1974]. The trick is especially useful for solving Lagrangian saddle point problems when minimizing quadratic energies subject to linear equality ...

On deriving the generalized Drazin inverse of block matrices in a Banach algebra
, 2016 This paper is devoted to the generalized Drazin inverse of a block matrix x = [a b c d] in a Banach algebra A, under specic conditions. We focus on deriving formulae for the generalized Drazin inverse of x in terms of the generalized Drazin inverses of ...
