On interval number in cycle convexity [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
Recently, Araujo et al. [Manuscript in preparation, 2017] introduced the notion of Cycle Convexity of graphs. In their seminal work, they studied the graph convexity parameter called hull number for this new graph convexity they proposed, and they ...

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

open access: yesMolecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Minimal Interval Completion Through Graph Exploration

open access: yes, 2006
International audienceGiven an arbitrary graph G=(V,E) and an interval supergraph H=(V,F), we say that H is an interval completion of G. The graph H is called a minimal interval completion of G if, for any sandwich graph H ′ = (V,F ′) between G and H, H ′

Steiner intervals in graphs

open access: yesDiscrete Applied Mathematics, 1998
If \(S\) is a subset of the vertex set of a connected graph \(G\), then the Steiner distance \(d(S)\) of \(S\) is the minimum number of edges of a connected subgraph of \(G\) that contains \(S\); this subgraph is always a tree and is called a Steiner tree for \(S\). The Steiner interval \(I(S)\) of \(S\) is the set of all vertices of \(G\) which lie in

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma

open access: yesMolecular Oncology, EarlyView.
Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

Independent sets of maximum weight in apple-free graphs [PDF]

open access: yes, 2010
We present the first polynomial-time algorithm to solve the maximum weight independent set problem for apple-free graphs, which is a common generalization of several important classes where the problem can be solved efficiently, such as claw-free graphs,

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

A Reduction of the Graph Reconstruction Conjecture

open access: yesDiscussiones Mathematicae Graph Theory, 2014
A graph is said to be reconstructible if it is determined up to isomor- phism from the collection of all its one-vertex deleted unlabeled subgraphs. Reconstruction Conjecture (RC) asserts that all graphs on at least three vertices are reconstructible. In

Interval matroids and graphs

open access: yesDiscrete Mathematics, 1979
AbstractA base of the cycle space of a binary matroid M on E is said to be convex if its elements can be totally ordered in such a way that for every e ε E the set of elements of the base containing e is an interval. We show that a binary matroid is cographic iff it has a convex base of cycles; equivalently, graphic matroids can be represented as ...

Minimal interval completion through graph exploration

open access: yes, 2009
Given an arbitrary graph G=(V,E) and an interval graph H=(V,F) with E⊆F we say that H is an interval completion of G. The graph H is called a minimal interval completion of G if, for any sandwich graph H′=(V,F′) with E⊆F′⊂F, H′ is not an interval graph ...
