Backbone colouring of chordal graphs
Procedia Computer ScienceA proper $k$-colouring of a graph $G=(V,E)$ is a function $c: V(G)\to \{1,\ldots,k\}$ such that $c(u)\neq c(v)$ for every edge $uv\in E(G)$. The chromatic number $χ(G)$ is the minimum $k$ such that there exists a proper $k$-colouring of $G$. Given a spanning subgraph $H$ of $G$, a $q$-backbone $k$-colouring of $(G,H)$ is a proper $k$-colouring $c$ of ...

Political Psychology, EarlyView.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 ...

A New Characterization of Unichord-Free Graphs
Discussiones Mathematicae Graph Theory, 2015 Unichord-free graphs are defined as having no cycle with a unique chord. They have appeared in several papers recently and are also characterized by minimal separators always inducing edgeless subgraphs (in contrast to characterizing chordal graphs by ...

Aging Cell, Volume 25, Issue 2, February 2026.MSC‐derived exosomes deliver lnc‐AGT‐3 to vascular endothelial cells, where it binds hnRNP K in the nucleus. This interaction inhibits p53 ubiquitination, enhancing p53 stabilization and transcriptional activation of anti‐angiogenic targets TSP1. Consequently, p53‐mediated signaling is potentiated, effectively suppressing choroidal neovascularization ...

Discussiones Mathematicae Graph Theory, 2019 Several recent papers have investigated unichord-free graphs—the graphs in which no cycle has a unique chord. This paper proposes a concept of strongly unichord-free graph, defined by being unichord-free with no cycle of length 5 or more having exactly ...

Endothelial BMP6 Drives Hemodynamic‐Dependent VSMCs Calcification in Carotid Atherosclerosis
Advanced Science, Volume 13, Issue 2, 9 January 2026.The study demonstrates that endothelial cell (EC)‐derived BMP6 promotes the osteogenic differentiation of vascular smooth muscle cells (VSMCs) through cell‐cell interactions. Additionally, the researchers preliminarily explore the driving effect of hemodynamic factors on BMP6‐induced calcification and reveal the regulatory role of KLF4 on BMP6.

Clinical and Translational Medicine, Volume 16, Issue 1, January 2026.DCAF7 is up‐regulated in various tumours and correlates with poor prognosis, particularly in LIHC. High DCAF7 expression is linked to CD4+ T cell infiltration, up‐regulation of immune checkpoint genes and increased tumour mutational burden, suggesting a role in tumour immune escape.
