Cell Proliferation, EarlyView.Single‐cell and spatial profiling reveal that lymphovascular space invasion in endometrioid endometrial carcinoma is driven by coordinated interactions among metastatic epithelium, fibroblasts, immune cells, and endothelium. This multicellular network promotes matrix remodelling, angiogenesis, and immune evasion, forming a pro‐metastatic niche that ...

Chordality Properties and Hyperbolicity on Graphs
The Electronic Journal of Combinatorics, 2016 Let $G$ be a graph with the usual shortest-path metric. A graph is $\delta$-hyperbolic if for every geodesic triangle $T$, any side of $T$ is contained in a $\delta$-neighborhood of the union of the other two sides. A graph is chordal if every induced cycle has at most three edges.

The Economic History Review, EarlyView.Abstract The 1430s were characterized by extreme weather conditions, food and fodder shortages, and high mortalities among animals and humans, although the severity of events and their consequences in England have received limited attention. The economic downturn and the depressed customary land market in this decade marked the beginning of the Great ...

Journal of Management Studies, EarlyView.Abstract Cultural entrepreneurship research emphasizes entrepreneurs’ use of cultural resources to influence audience evaluations through resonance. However, the process by which such cultural resonance is achieved remains underexplored, particularly as an intermediary outcome.

Finite Element Modelling of Rocking and Hybrid Precast Walls under Seismic Loading
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1924-1941, 25 July 2026.ABSTRACT In recent years, self‐centring systems have received considerable research interest in the seismic design of precast concrete structures for their ability to limit damage and satisfy resilience requirements. Rocking and hybrid structural walls, characterised by the formation of a single gap at the wall–foundation interface, mitigate damage by ...

Towards Characterization of Five‐List‐Colorability of Toroidal Graphs
Journal of Graph Theory, Volume 112, Issue 3, Page 267-275, July 2026.ABSTRACT Through computer‐assisted enumeration, we list minimal obstructions for 5‐choosability of graphs on the torus with the following additional property: There exists a cyclic system of non‐contractible triangles around the torus where the consecutive triangles are at distance at most four.

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.

Treewidth Versus Clique Number. V. Further Connections With Tree‐Independence Number
Journal of Graph Theory, Volume 112, Issue 3, Page 337-351, July 2026.ABSTRACT We continue the study of ( tw , ω )‐bounded graph classes, that is, hereditary graph classes in which large treewidth is witnessed by the presence of a large clique, and the relation of this property to boundedness of the tree‐independence number, a graph parameter introduced independently by Yolov in 2018 and by Dallard, Milanič, and Štorgel ...
