Maximal outerplanar graphs as chordal graphs, path-neighborhood graphs, and triangle graphs [PDF]
Maximal outerplanar graphs are characterized using three different classes of graphs. A path-neighborhood graph is a connected graph in which every neighborhood induces a path. The triangle graph $T(G)$ has the triangles of the graph $G$ as its vertices,

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.

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.

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 ...

On the uniqueness of collections of pennies and marbles
Examples and CounterexamplesIn this note we study the uniqueness problem for collections of pennies and marbles. More generally, consider a collection of unit d-spheres that may touch but not overlap.

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)$\mathrm{Spin}(p,q)$.

The FASEB Journal, Volume 40, Issue 5, 15 March 2026.Single‐cell transcriptomic profiling reveals that endometrial polyps arise from estrogen‐driven disruption of stromal‐epithelial signaling. Stromal cells exhibit enhanced WNT, IGF, and VEGF pathways, promoting epithelial proliferation and vascular remodeling.
