Irredundancy in circular arc graphs
Discrete Applied Mathematics, 1993 An open neighbourhood of a vertex \(x\) in an undirected graph \(G\) is the set \(N(x)\) of all vertices adjacent to \(x\) in \(G\); its closed neighbourhood is \(N[x]=N(x) \cup \{x\}\). For a set \(S\) of vertices set \(N(S)=\bigcup_{x \in S}N(x)\) and \(N[S]=\bigcup_{x \in S} N[x]\). A subset \(X\) of the vertex set of \(G\) is called irredundant (or

On powers of circular arc graphs and proper circular arc graphs
Discrete Applied Mathematics, 1996 Let \(\mathcal K\) denote the class of circular arc graphs. The author gives a new proof that if a graph \(G\in {\mathcal K}\), then the power \(G^n\in {\mathcal K}\) for any positive integer \(n\). Moreover, he proves that if \(G^n\in {\mathcal K}\) then \(G^{n+2}\in {\mathcal K}\) and if \(\text{diam}(G^n)\geq 4\) then \(G^n\in {\mathcal K}\) implies

FEBS Open Bio, EarlyView.Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Drawing planar graphs with circular arcs [PDF]
Discrete & Computational Geometry, 1999 The authors study the problem of drawing planar graphs with circular arcs, while maintaining good angular resolution and small drawing area. They show the following: (1) There is an \(n\)-vertex planar graph requiring area exponential in \(n\) for any drawing using single-circle arcs for edges and having good angular resolution. (2) Let \(d(v)\) be the

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Dysregulated lipid metabolism, which can affect remyelination and neural repair, has not been extensively investigated in progressive multiple sclerosis (PMS). The goal was to examine whether dysregulated cholesterol metabolism was associated with disability in PMS. Methods The study sample comprised 53 Severe PMS patients (Expanded

Jixie chuandong, 2019 Because of the particularity of the design of double circular arc gears, the influence of tooth surface friction on the transmission of double circular arc gears is often neglected in the past research on the dynamic characteristics of double circular ...

Modification Problems Toward Proper (Helly) Circular-Arc Graphs [PDF]
, 2023 We present a 9^k ⋅ n^O(1)-time algorithm for the proper circular-arc vertex deletion problem, resolving an open problem of van ’t Hof and Villanger [Algorithmica 2013] and Crespelle et al. [Computer Science Review 2023]. Our structural study also implies

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
