Optimizing condition numbers [PDF]
SIAM Journal on Optimization, 2009 In this paper we study the problem of minimizing condition numbers over a compact convex subset of the cone of symmetric positive semidefinite $n\times n$ matrices. We show that the condition number is a Clarke regular strongly pseudoconvex function.

The Cayley-Dickson Construction in ACL2 [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 The Cayley-Dickson Construction is a generalization of the familiar construction of the complex numbers from pairs of real numbers. The complex numbers can be viewed as two-dimensional vectors equipped with a multiplication. The construction can be used

Structured Eigenvalue Condition Numbers [PDF]
SIAM Journal on Matrix Analysis and Applications, 2006 This paper investigates the effect of structure-preserving perturbations on the eigenvalues of linearly and nonlinearly structured eigenvalue problems. Particular attention is paid to structures that form Jordan algebras, Lie algebras, and automorphism groups of a scalar product.

Physical Review X, 2020 We introduce a new boundary condition which renders the flux-insertion argument for the Lieb-Schultz-Mattis-type theorems in two or higher dimensions free from the specific choice of system sizes.

Condition-Number-Regularized Covariance Estimation [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 2012 SummaryEstimation of high dimensional covariance matrices is known to be a difficult problem, has many applications and is of current interest to the larger statistics community. In many applications including the so-called ‘large p, small n’ setting, the estimate of the covariance matrix is required to be not only invertible but also well conditioned.

Bridge Condition Assessment Using D Numbers
The Scientific World Journal, 2014 Bridge condition assessment is a complex problem influenced by many factors. The uncertain environment increases more its complexity. Due to the uncertainty in the process of assessment, one of the key problems is the representation of assessment results.

Data integration across conditions improves turnover number estimates and metabolic predictions
Nature Communications, 2023 The construction of protein-constrained genome-scale metabolic models depends on the integration of organism-specific enzyme turnover numbers. Here, the authors show that correction of turnover numbers by simultaneous consideration of proteomics and ...
