Binomial edge ideals of weakly closed graphs

open access: yes, 2022
Closed graphs have been characterized by Herzog et al. as the graphs whose binomial edge ideals have a quadratic Gr\"obner basis with respect to a diagonal term order.

The regularity of edge ideals of graphs [PDF]

open access: yes, 2012
In this paper, we introduce some reduction processes on graphs which preserve the regularity of related edge ideals. Using these, an alternative proof for the theorem of R.

Translating whole‐genome doubling into precision medicine in cancer

open access: yesMolecular Oncology, EarlyView.
Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)

Spatial biology in cancer epigenetics

open access: yesMolecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Some results on the complement of a new graph associated to a commutative ring

open access: yesCommunications in Combinatorics and Optimization, 2017
The rings considered in this article are commutative with identity which admit at least one nonzero proper ideal‎. ‎Let $R$ be a ring‎. ‎We denote the collection of all ideals of $R$ by $\mathbb{I}(R)$ and $\mathbb{I}(R)\backslash \{(0)\}$ by $\mathbb{

The prestige economy of elite education: a Baudrillardian analysis of an aspirational English school

open access: yesLondon Review of Education, 2023
Academic entrepreneurial behaviours are increasingly a research field paralleling processes of capitalist commodification. We mobilise Baudrillard’s concepts to probe a school’s strategic communication methods symbolising class neoliberalism, which ...

Binomial edge ideals and conditional independence statements [PDF]

open access: yes, 2010
We introduce binomial edge ideals attached to a simple graph G and study their algebraic properties. We characterize those graphs for which the quadratic generators form a Gröbner basis in a lexicographic order induced by a vertex labeling.

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

open access: yesMolecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

Complementary edge ideals

open access: yesExpositiones Mathematicae
Let $S=K[x_1,\dots,x_n]$ be the polynomial ring over a field $K$ and $I\subset S$ be a squarefree monomial ideal generated in degree $n-2$. Motivated by the remarkable behavior of the powers of $I$ when $I$ admits a linear resolution, as established in [11], in this work we investigate the algebraic and homological properties of $I$ and its powers.
