On Non-Essential Edges in 3-Connected Graphs

Graphs and Combinatorics, 2000
An edge \(e\) in a simple 3-connected graph is deletable (contractible), if the deletion \(G-e\) (contraction \(G/e\)) is still simple and 3-connected. Let \(a,b\), and \(c\) be three non-negative integers. If there exists a simple 3-connected graph with exactly \(a\) edges which are deletable but not contractible, exactly \(b\) edges which are ...

On Essential and Non-Essential Descriptions of Multilattices

Mathematics and Mechanics of Solids, 2004
I exhibit conditions necessary and sufficient for a crystal multilattice description to be “non-essential”, and give a procedure which yields the “essential” description.

Dimension on non-essential submodules

Journal of Algebra and Its Applications, 2019
In this paper, we introduce and study the concepts of non-essential Krull dimension and non-essential Noetherian dimension of an [Formula: see text]-module, where [Formula: see text] is an arbitrary associative ring. These dimensions are ordinal numbers and extend the notion of Krull dimension.

When cancer needs what's non-essential

Nature Cell Biology, 2017
The non-essential amino acids serine and glycine are critical for proliferative metabolism. A study in Nature now finds that dietary serine and glycine deprivation inhibits growth of some tumours. Whether this dietary intervention is effective depends on both the oncogenic context and tumour tissue of origin.

Endogenous viral genes are non-essential in the chicken

Nature, 1979
DNA sequences homologous to the genomes of type C retroviruses are widespread among vertebrates. Ten genetic loci containing endogenous viral DNA sequences have been documented in the white Leghorn chicken alone. Six of these genetic loci are associated with the production of virus or of viral proteins in embryonic fibroblasts (refs 2--4, and S.M.A., L,

Brain areas essential or non-essential for emesis

Brain Research, 1994
This study was undertaken to better delineate those brain regions that are either essential or non-essential for vomiting. Fictive vomiting, identified by a characteristic pattern of respiratory nerve discharge, was induced by a combination of emetic drugs and electrical stimulation of abdominal vagal afferents in decerebrate, paralyzed cats.
