Perfectness of the essential graph for modules over commutative rings [PDF]
AUT Journal of Mathematics and ComputingLet $R$ be a commutative ring and $M$ be an $R$-module. The essential graph of $M$, denoted by $EG(M)$ is a simple graph with vertex set $Z(M) \setminus\operatorname{Ann}(M)$ and two distinct vertices $x,y \in Z(M) \setminus \operatorname{Ann}(M)$ are ...

Forbidden induced pairs for perfectness and ω-colourability of graphs
, 2022 We characterise the pairs of graphs {X, Y} such that all {X, Y}-free graphs(distinct from C5) are perfect. Similarly, we characterise pairs {X, Y} such that all {X, Y}-free graphs (distinct from C5) are ω-colourable (that is, their chromatic number is ...

Advances in Applied Mathematics, 2016 We introduce a variant of de Bruijn words that we call perfect necklaces. Fix a finite alphabet. Recall that a word is a finite sequence of symbols in the alphabet and a circular word, or necklace, is the equivalence class of a word under rotations. For positive integers k and n, we call a necklace (k,n)-perfect if each word of length k occurs exactly ...

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Molecular Oncology, EarlyView.Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Perfect matchings and perfect squares
Journal of Combinatorial Theory, Series A, 1994 The author investigates (perfect) matchings of a large class of graphs with 4-fold rotational symmetry. It is proved by mostly combinatorial arguments that the number of such matchings is always a square or double a square. This result has an interesting application to tilings by dominoes.
