Species means and residual P-matrices

, 2016
The data are species climatic means (extracted from WorldClim database for all localities the species are reported to occur) and morphological means (21 linear skull distances: definitions of abbreviations are in the ReadMe file).

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

A new subclass of P-matrices

Linear Algebra and its Applications, 2004
The paper is concerned with a class of matrices for which it is easy to calculate bounds for the solution of a linear complementarity problem. The paper generalizes iterative methods for linear complementarity problems with interval data.

On completion problems for various classes of P-matrices

Linear Algebra and its Applications, 2006
A \(P\)-matrix is a real square matrix having every principal minor positive; a Fischer matrix is a \(P\)-matrix satisfying Fischer's inequality for all principal submatrices, i.e., \(\det A[\alpha] \det A[\beta] \geq \det A[\alpha \cup \beta]\) where \(\alpha, \beta \in 2^{\{1, ..., n\}}\) with \(\alpha \cap \beta = \emptyset\).

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

P-Matrices: An equivalent characterisation

Journal of Algebra, 1988
A square matrix is a P-matrix if all its principal minors are positive. The class of P-matrices includes the positive definite matrices as well as totally positive matrices. P-matrices have interesting properties relating to stability so that different characterizations of such matrices seem to be of importance. Let M be any subset of \(N=\{1,2,...,n\}\

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

FEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

A novel substitution matrix fitted to the compositional bias in Mollicutes improves the prediction of homologous relationships

BMC Bioinformatics, 2011
Background Substitution matrices are key parameters for the alignment of two protein sequences, and consequently for most comparative genomics studies.
