The Colin de Verdi
In 1990, Y. Colin de Verdi ere introduced a new graph parameter (G), based on spectral properties of matrices associated with G. He showed that (G) is monotone under taking minors and that planarity of G is characterized by the inequality (G) 3. Recently Lovv asz and Schrijver showed that linkless embeddability of G is characterized by the inequality (G) 4. In this paper we give an overview of ...
متن کاملColin de Verdiere parameters of chordal graphs
The Colin de Verdière parameters, μ and ν, are defined to be the maximum nullity of certain real symmetric matrices associated with a given graph. In this work, both of these parameters are calculated for all chordal graphs. For ν the calculation is based solely on maximal cliques, while for μ the calculation depends on split subgraphs. For the case of μ our work extends some recent work on com...
متن کاملHigh Tech versus Low Tech Training
The United States Marine Corps has some of the most advanced weapons systems and training in the world, yet they make extensive use of “low tech” training tools. Sand table exercises and tactical decision games are used by Marines all over the world, at sea and on land. Although the U.S. Department of Defense has a nearly $18 billion annual training budget, the Marines choose to teach decision ...

ased assessment of associations with disease phenotypes. This approach relieves the investigator of having to conjure up candidate genes, and will lead to unexpected and often inexplicable findings, as have been reported for diabetes, a prime example of a multigenic trait.3 To query such a large number of SNPs, patient samples must be substantial and the analytical approach must be rigorous. Ne...
متن کاملHigh-tech hazards.
In silico screening methods based on the 3D structures of the ligands or of the proteins have become an essential tool to facilitate the drug discovery process. To achieve such process, the 3D structures of the small chemical compounds have to be generated. In addition, for ligand-based screening computations or hierarchical structurebased screening projects involving a rigid-body docking step,...
