A second-level diagonal preconditioner for single-step SNPBLUP
Genetics Selection Evolution, 2019 Background The preconditioned conjugate gradient (PCG) method is an iterative solver of linear equations systems commonly used in animal breeding. However, the PCG method has been shown to encounter convergence issues when applied to single-step single ...

A condition for diagonalization modulo arbitrary norm ideals
Journal of Functional Analysis, 2008 Let \(\mathcal C\) be a norm ideal and \((A_1, \dots,A_n)\) be a commuting tuple of self-adjoint operators on a separable Hilbert space \(\mathcal H\). Continuing previous investigations from a series of articles in the same journal, the author considers the problem of determining whether or not \((A_1,\dots,A_n)\) can be simultaneously diagonalized ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

A new tri-diagonal matrix invariance property. [PDF]
, 2017 We state and prove an invariance property, with respect to matrix power, for those n−1 immediate off-diagonal ratios of a tri-diagonal n-square matrix.

Subconvexity for additive equations: Pairs of undenary cubic forms [PDF]
, 2014 We investigate pairs of diagonal cubic equations with integral coefficients. For a class of such Diophantine systems with 11 or more variables, we are able to establish that the number of integral solutions in a large box is at least as large as the ...
