The Integration of Norse‐Derived Terms in English: Effects of Formal Similarity1
Transactions of the Philological Society, Volume 123, Issue 3, Page 556-591, November 2025.Abstract Language change arising from language contact is a complex phenomenon. Peter Matthews encouraged researchers to consider it as firmly grounded in the behaviour of individual speakers. We apply this perspective to investigate the integration of Norse‐derived terms into medieval English, testing for the effect of their phonetic similarity to ...

Studies in Applied Mathematics, Volume 155, Issue 5, November 2025.ABSTRACT Various biological cells secrete diffusing chemical compounds into their environment for communication purposes. Secretion usually takes place over the cell membrane in a spatially heterogeneous manner. Mathematical models of these processes will be part of more elaborate models, for example, of the movement of immune cells that react to ...

A Schur Method for Low-rank Matrix Approximation
, 1996 The usual way to compute a low-rank approximant of a matrix H is to take its singular value decomposition (SVD) and truncate it by setting the small singular values equal to 0. However, the SVD is computationally expensive.

Modeling Dynamic Electrochemical Impedance Spectroscopy Using a Linearization Technique
ChemElectroChem, Volume 12, Issue 18, September 15, 2025.This article investigates the modeling of dynamic electrochemical impedance spectroscopy. Using a linearization technique, three mathematical models are defined – dynamic, stationary, and filtered. The results show a closeness of the dynamic model to the experimental practice and significant effects of nonstationarity in the low‐frequency region.

Efficient Algorithm for Minimal-Rank Matrix Approximations
, 2008 For a given matrix H which has d singular values larger than ε, an expression for all rank-d approximants ˆH such that (H − ˆH) has 2-norm less than ε is derived.

Good intermediate-rank lattice rules based on the weighted star discrepancy [PDF]
, 2006 We study the problem of constructing good intermediate-rank lattice rules in the sense of having a low weighted star discrepancy. The intermediate-rank rules considered here are obtained by “copying” rank-1 lattice rules.

Approche variationnelle de la fonction rang : relaxation convexe, sous-différentiation généralisée, régularisation-approximation de Moreau [PDF]
, 2013 Dans ce mémoire de these, nous étudions la fonction rang du point de vue variationnel. La raison pour laquelle nous nous intéressons à cette fonction est qu'elle apparaît comme une fonction objectif (ou comme fonction contrainte) dans divers problèmes d ...

Rank-preserving geometric means of positive semi-definite matrices
, 2013 peer reviewedThe generalization of the geometric mean of positive scalars to positive definite matrices has attracted considerable attention since the seminal work of Ando.

Indexing approximants of icosahedral quasicrystals
, 1999 It is well known that the crystallography of approximants is directly related to that of the parent quasicrystal, once its unit-cell vectors are identified as parallel projections of certain N-dimensional lattice nodes {\bf A}^{i}.

Structured low-rank approximation with missing data
The approach of SIAM J. Matrix Anal. Appl., 26(4):1083--1099 for solving structured total least squares problems is generalized to weighted structured low-rank approximation with missing data. The method proposed is based on elimination of the correction
