Units in group rings and blocks of Klein four or dihedral defect

Bulletin of the London Mathematical Society, EarlyView.
Abstract We obtain restrictions on units of even order in the integral group ring ZG$\mathbb {Z}G$ of a finite group G$G$ by studying their actions on the reductions modulo 4 of lattices over the 2‐adic group ring Z2G$\mathbb {Z}_2G$. This improves the “lattice method” which considers reductions modulo primes p$p$, but is of limited use for p=2$p=2 ...

Arithmetic sparsity in mixed Hodge settings

Bulletin of the London Mathematical Society, EarlyView.
Abstract Let X$X$ be a smooth irreducible quasi‐projective algebraic variety over a number field K$K$. Suppose X$X$ is equipped with a p$p$‐adic étale local system compatible with an admissible graded‐polarized variation of mixed Hodge structures on the complex analytification of XC$X_{\operatorname{\mathbb {C}}}$.

Explicit constructions of short virtual resolutions of truncations

Bulletin of the London Mathematical Society, EarlyView.
Abstract We propose a concept of truncation for arbitrary smooth projective toric varieties and construct explicit cellular resolutions for nef truncations of their total coordinate rings. We show that these resolutions agree with the short resolutions of Hanlon, Hicks, and Lazarev, which were motivated by symplectic geometry, and we use our definition

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.

Vertebral Growth Modulation Through Periosteal Resection and Fixed Length Deformity Overcorrection: Computational and In Vivo Pilot Study

JOR SPINE, Volume 8, Issue 4, December 2025.
The feasibility of using growth promoting strategies (vertebral periosteal resection and distraction) was investigated via computational and in vivo analysis. Computational analysis demonstrated that there is an increasing mechanical benefit to utilizing concave distraction over convex compression during spinal deformity correction.

Dual spaces of geodesic currents

Journal of Topology, Volume 18, Issue 4, December 2025.
Abstract Every geodesic current on a hyperbolic surface has an associated dual space. If the current is a lamination, this dual embeds isometrically into a real tree. We show that, in general, the dual space is a Gromov hyperbolic metric tree‐graded space, and express its Gromov hyperbolicity constant in terms of the geodesic current.

Fouling in Emulsion Polymerization: Fundamentals and Methods of Investigation

Journal of Applied Polymer Science, Volume 142, Issue 43, November 15, 2025.
ABSTRACT The current understanding of fouling in emulsion polymerization is summarized from an engineering perspective and from a physical‐chemistry perspective. Emulsion polymerization in semibatch mode offers better control over the number of particles and side reactions than batch mode. Both reaction fouling and particulate fouling are observed, the

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

The Anatomical Record, Volume 308, Issue 11, Page 2896-2912, November 2025.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...
