We review the work of Dominic Welsh (1938-2023), tracing his remarkable influence through his theorems, expository writing, students, and interactions. He was particularly adept at bringing different fields together and fostering the development of m

Although the unavoidable minors of large 3-connected matroids were found nearly thirty years ago, there has been little progress on solving the corresponding problem for large 4-connected matroids. This paper aims to take a step towards solving that

In 1961, Dirac showed that chordal graphs are exactly the graphs that can be constructed from complete graphs by a sequence of clique-sums. In an earlier paper, by analogy with Dirac's result, we introduced the class of $GF(q)$-chordal matroids as th

The breadth of a tangle $\mathcal{T}$ in a matroid is the size of the largest spanning uniform submatroid of the tangle matroid of $\mathcal{T}$. The matroid $M$ is weakly 4-connected if it is 3-connected and whenever $(X,Y)$ is a partition of $E(M)$

Abstract Peptidylarginine deiminase IV (PADI4, PAD4) deregulation promotes the development of autoimmunity, cancer, atherosclerosis and age-related tissue fibrosis. PADI4 additionally mediates immune responses and cellular reprogramming, although the

Abstract PEGylation (the covalent attachment of one or more poly(ethylene glycol) (PEG) units to a therapeutic) is a well-established technique in the pharmaceutical industry to increase blood-residence time and decrease immunogenicity. A challenging

Targets are matroids that arise from a nested sequence of flats in a projective geometry. This class of matroids was introduced by Nelson and Nomoto, who found the forbidden induced restrictions for binary targets. This paper generalizes their result

Let $G$ be a graph such that, whenever two vertices $x$ and $y$ of $G$ are joined by three internally disjoint paths, $x$ and $y$ are adjacent. Jamison and Mulder determined that the set of such graphs coincides with the set of graphs that can be bui

A graph is chordal if every cycle of length at least four has a chord. In 1961, Dirac characterized chordal graphs as those graphs that can be built from complete graphs by repeated clique-sums. Generalizing this, we consider the class of simple $GF(

Introduction: Reactive angioendotheliomatosis (RAE) is a rare, benign, angioproliferative disorder with poorly understood aetiopathogenesis. It is characterised by vascular occlusion that occurs in patients with coexistent systemic or autoimmune dise
