On locating–dominating sets in infinite grids

, 2006
Determining a malfunctioning component in a processor network gives the motivation for locating–dominating sets. It is shown that the smallest possible density of a locating–dominating set in the king grid equals 1/5 and in the hexagonal mesh 1/3 ...

Partitioning a graph into a dominating set, a total dominating set, and something else [PDF]

, 2009
A recent result of Henning and Southey (A note on graphs with disjoint dominating and total dominating set, {\it Ars Comb.} {\bf 89} (2008), 159--162) implies that every connected graph of minimum degree at least three has a dominating set $D$ and a ...

Structural Parameterization of Locating-Dominating Set and Test Cover

We investigate structural parameterizations of two identification problems: LOCATING-DOMINATING SET and TEST COVER. In the first problem, an input is a graph $G$ on $n$ vertices and an integer $k$, and one asks if there is a subset $S$ of $k$ vertices ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

An extension of locating-total domination problem and its complexity

An r-dominating set (r-total dominating set) of G is a subset S of V (G) for which Nr(u)∩S is non-empty for all u not in S (for all u in V (G)).

Locating-total domination in claw-free cubic graphs

, 2012
In this paper, we continue the study of locating-total domination in graphs. A set S of vertices of a graph G is a total dominating set of G if every vertex of G is adjacent to a vertex in S.

EPIDEMIC CONTACT TRACING AND CONTAINMENT IN FUZZY SOCIAL GRAPHS USING STRENGTH-BASED FUZZY LOCATION TOTAL DOMINATION SETS

International Journal of Applied Mathematics
In this study, we investigate the concept of fuzzy locating total dominating sets (FLTDS) in simple connected fuzzy graphs. A subset   is defined as a FLTDS if every  if each vertex outside of  is next to at least one  vertex via a strong arc (fuzzy domination), and each such vertex has a unique strength-based representation vector with respect to ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.
