Debiasing piecewise deterministic Markov process samplers using couplings
Scandinavian Journal of Statistics, EarlyView.Abstract Monte Carlo methods—such as Markov chain Monte Carlo (MCMC) and piecewise deterministic Markov process (PDMP) samplers—provide asymptotically exact estimators of expectations under a target distribution. There is growing interest in alternatives to this asymptotic regime, in particular in constructing estimators that are exact in the limit of ...

Residually rationally solvable one‐relator groups
Bulletin of the London Mathematical Society, EarlyView.Abstract We show that the intersection of the rational derived series of a one‐relator group is rationally perfect and is normally generated by a single element. As a corollary, we characterise precisely when a one‐relator group is residually rationally solvable.

Journal of Graph Theory, Volume 110, Issue 4, Page 448-456, December 2025.ABSTRACT A dominating K t‐model in a graph G is a sequence ( T 1 , … , T t ) of pairwise disjoint non‐empty connected subgraphs of G, such that for 1 ⩽ i < j ⩽ t every vertex in T j has a neighbour in T i. Replacing ‘every vertex in T j’ by ‘some vertex in T j’ retrieves the standard definition of K t‐model, which is equivalent to K t being a minor of ...

Is every product system concrete?
Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.Abstract Is every product system of Hilbert spaces over a semigroup P$P$ concrete, that is, isomorphic to the product system of an E0$E_0$‐semigroup over P$P$? The answer is no if P$P$ is discrete, cancellative and does not embed in a group. However, we show that the answer is yes for a reasonable class of semigroups.

Spanning Plane Subgraphs of 1‐Plane Graphs
Journal of Graph Theory, Volume 110, Issue 3, Page 290-297, November 2025.ABSTRACT A graph drawn on the plane is called 1‐plane if each edge is crossed at most once by another edge. In this paper, we show that every 4‐edge‐connected 1‐plane graph has a connected spanning plane subgraph. We also show that there exist infinitely many 4‐connected 1‐plane graphs that have no 2‐connected spanning plane subgraphs.

The necessity of motoric engagement in enhancing route memory
British Journal of Psychology, Volume 116, Issue 4, Page 1164-1188, November 2025.Abstract The relative contribution of decision‐making and motor engagement at encoding, on route memory, was examined using virtual reality (VR). During encoding, participants explored 12 virtual environments for 40 s each. Navigation strategy during encoding was manipulated within‐subjects.

Developments in Functional Regression Model for Network Structured Data
Environmetrics, Volume 36, Issue 7, October 2025.ABSTRACT In this paper, we propose a Network‐Weighted Functional Regression (NWFR) model, an extension of Spatially Weighted Functional Regression (SWFR) to functional data defined on network‐structured settings. To assess predictive uncertainty, we develop a functional conformal prediction procedure that yields a distribution‐free prediction interval ...

Abundant Neighborhoods, Two‐Sided Markets, and Maximal Matchings
Naval Research Logistics (NRL), Volume 72, Issue 7, Page 1022-1035, October 2025.ABSTRACT I introduce a new graph‐theoretic property called abundant neighborhoods. This property is motivated by studying the thickness of economic markets. A vertex is, roughly, guaranteed to match if and only if it has an abundant neighborhood.

Stability of Interdiction Strategies in Quickest Flow Networks
Networks, Volume 86, Issue 3, Page 263-281, October 2025.ABSTRACT Many, if not all, societies have experienced natural disasters, public protests, traffic congestion, and the smuggling of dangerous goods, among other similar events. Such decision‐making and managerial problems can be studied using a game‐theoretic approach on specific networks.

A Gaussian Process Regression IV Model for PV Outdoor Data
Progress in Photovoltaics: Research and Applications, Volume 33, Issue 10, Page 1093-1108, October 2025.Each electrical performance measure of PV modules needs to be considered in the context of dynamically changing outdoor conditions. In this paper, we introduce a statistical model based on Gaussian process regressions designed to analyze PV outdoor data aiming to utilize all available information.
