Total Semirelib Graph [PDF]

, 2013
In this paper, the concept of Total semirelib graph of a planar graph is introduced. Authors present a characterization of those graphs whose total semirelib graphs are planar, outer planar, Eulerian, hamiltonian with crossing number ...

Pragmatic Graph Rewriting Modifications [PDF]

, 1999
We present new pragmatic constructs for easing programming in visual graph rewriting programming languages. The first is a modification to the rewriting process for nodes the host graph, where nodes specified as 'Once Only' in the LHS of a rewrite match ...

Complementary vanishing graphs

Linear Algebra and its Applications
Given a graph $G$ with vertices $\{v_1,\ldots,v_n\}$, we define $\mathcal{S}(G)$ to be the set of symmetric matrices $A=[a_{i,j}]$ such that for $i\ne j$ we have $a_{i,j}\ne 0$ if and only if $v_iv_j\in E(G)$. Motivated by the Graph Complement Conjecture, we say that a graph $G$ is complementary vanishing if there exist matrices $A \in \mathcal{S}(G ...

On self-graphoidal graphs and their complements

Kuwait Journal of Science
The graphoidal graph G of graph H is the graph obtained by taking graphoidal cover Ψ of H as vertices and two vertices are adjacent if and only if the corresponding paths have a non-empty intersection.

自余弱弦图(On self-complementary weakly chordal graphs)

Zhejiang Daxue xuebao. Lixue ban, 2010
The class of self-complementary (sc) weakly chordal graphs is studied, which is a generalization of self-complementary chordal graphs, lower and upper bounds for the number of two-pairs in sc weakly chordal graphs have been obtained.

On complementary graphs with no isolated vertices

Discrete Mathematics, 1978
AbstractLet G denote the complement of a graph G, and x(G), β1(G), β4(G), α0(G), α1(G) denote respectively the chromatic number, line-independence number, point-independence number, point-covering number, line-covering number of G, Nordhaus and Gaddum showed that for any graph G of order p, {2√p} ⩽ x(G) + x(G) ⩽ p + 1 and p ⩽ x(G)·x(G) ⩽ [(12(p + 1))2].

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Complementary algorithms for graphs and percolation [PDF]

Physical Review E, 2007
A pair of complementary algorithms are presented. One of the pair is a fast method for connecting graphs with an edge. The other is a fast method for removing edges from a graph. Both algorithms employ the same tree based graph representation and so, in concert, can arbitrarily modify any graph.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

The International Collaboration on Complementary Therapy Resources (ICCR) : working together to improve online CAM information [PDF]

, 2011
Use of the Internet to find health information is increasing dramatically but the quality of information, particularly on complementary and alternative medicine (CAM) is variable.
