Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs
Communications on Pure and Applied Mathematics, Volume 79, Issue 4, Page 1012-1072, April 2026.Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure

Component graphs of vector spaces and zero-divisor graphs of ordered sets
AKCE International Journal of Graphs and CombinatoricsIn this paper, nonzero component graphs and nonzero component union graphs of finite-dimensional vector spaces are studied using the zero-divisor graph of a specially constructed 0–1-distributive lattice and the zero-divisor graph of rings.

Recoloring via Modular Decomposition
Journal of Graph Theory, Volume 111, Issue 4, Page 113-123, April 2026.ABSTRACT The reconfiguration graph of the k‐colorings of a graph G, denoted R k ( G ), is the graph whose vertices are the k‐colorings of G and two colorings are adjacent in R k ( G ) if they differ in color on exactly one vertex. A graph G is said to be recolorable if R ℓ ( G ) is connected for all ℓ ≥ χ ( G ) + 1.

New graph classes characterized by weak vertex separators and two-pairs
AKCE International Journal of Graphs and Combinatorics, 2017 A set of vertices whose deletion from a graph would increase the distance between two remaining vertices is called a weak vertex separator of the graph. Two vertices form a two-pair if all chordless paths between them have length .

MedComm, Volume 7, Issue 4, April 2026.Illustration of the microenvironment factors driving malignant progression in MPNSTs. ABSTRACT Neurofibromatosis type 1 (NF1) is characterized by the development of benign plexiform neurofibromas (PNFs). In 10%–15% of patients, these tumors undergo malignant transformation into aggressive malignant peripheral nerve sheath tumors (MPNSTs).

Small Structures, Volume 7, Issue 4, April 2026.A novel 4D fabrication method creates wrinkled, porous textiles mimicking biological tissue mechanics with J‐shaped stress–strain behavior. By combining electrospinning and melt electrowriting, these hybrid materials offer tunable stiffness and pre‐stretching control, enabling seamless integration with diverse tissues. Ideal for wearable strain sensors,

Automating the analysis of public saliency and attitudes toward biodiversity from digital media
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring public attitudes toward wildlife provides crucial insights into human relationships with nature and helps monitor progress toward Global Biodiversity Framework targets. Yet, conducting such assessments at a global scale presents challenges.

Efficient Minus and Signed Domination in Proper Interval Graphs with a Totally Unimodular Structure
AxiomsThe efficient minus domination problem (EMDP) and the efficient signed domination problem (ESDP) are domination-type problems in graphs. These problems are known to be NP-complete on chordal graphs and polynomially solvable on chain interval graphs ...

Political Psychology, Volume 47, Issue 2, April 2026.Abstract Informed by the information‐deficit model, this preregistered survey experiment based on a random sampling of the Dutch population register (n = 2792) assesses how exposure to information about ethnic discrimination inspires adult belief change, especially how it affects (a) perceptions of ethnic inequality, (b) meritocratic explanations of ...

Noncommutative polygonal cluster algebras
Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.Abstract We define a new family of noncommutative generalizations of cluster algebras called polygonal cluster algebras. These algebras generalize the noncommutative surfaces of Berenstein–Retakh, and are inspired by the emerging theory of Θ$\Theta$‐positivity for the groups Spin(p,q)$\mathrm{Spin}(p,q)$.
