2003 Discrete Mathematics  
In this paper, we present a new class of graphs named quasi-locally paw-free (QLP) graphs.  ...  This subclass contains K4-free graphs and chordal graphs.  ...  In this paper, we introduce a new class of graphs called quasi-locally paw-free (QLP) graphs, where a paw is the graph induced by the vertices a; b; c; d and the edges ab; ac; ad; cd.  ...

Computing Small Pivot-Minors [chapter]

Konrad K. Dabrowski, François Dross, Jisu Jeong, Mamadou Moustapha Kanté, O-joung Kwon, Sang-il Oum, Daniël Paulusma
2018 Lecture Notes in Computer Science  
For a graph H, determine whether the class of H-pivot-minor-free graphs is well-quasi-ordered by the induced subgraph relation.  ...  By pivoting one edge, the diamond can be obtained from the paw and so (i) and (ii) are equivalent.  ...

Classes of perfect graphs

Stefan Hougardy
2006 Discrete Mathematics  
The Strong Perfect Graph Conjecture, suggested by Claude Berge in 1960, had a major impact on the development of graph theory over the last forty years.  ...  It has led to the definitions and study of many new classes of graphs for which the Strong Perfect Graph Conjecture has been verified.  ...  Acknowledgement I am grateful to Mariano Zelke and Valentin Ziegler for some help in preparing the final version of this paper. I thank Adrian Bondy, Chính T.  ...

Graphene and Some of its Structural Analogues: Full-potential Density Functional Theory Calculations [article]

Gautam Mukhopadhyay, Harihar Behera
2013 arXiv   pre-print
While our calculations corroborate some of the reported results based on different methods, our results on ZnSe, the two dimensional bulk modulus of ML-GeC, ML-AlN, ML-GaN, ML-ZnO and ML-ZnS and the effective  ...  masses of the charge carriers in these binary mono-layers are something new.  ...  Graphene = "graph" + "ene" and the term "graph" is derived from the word "graphite" and the suffix "ene" refers to polycyclic aromatic hydrocarbons.  ...

Nano-engineered microcapsules boost the treatment of persistent pain

Olga Kopach, Kayiu Zheng, Luo Dong, Andrei Sapelkin, Nana Voitenko, Gleb B. Sukhorukov, Dmitri A. Rusakov
2018 Drug Delivery  
Persistent pain remains a major health issue: common treatments relying on either repeated local injections or systemic drug administration are prone to concomitant side-effects.  ...  It depended on the QX-314 encapsulation levels, involved TRPV1channel-dependent cell permeability of QX-314, and showed no detectable side-effects.  ...  Disclosure statement No potential conflict of interest was reported by the authors.

Contribution of Cutaneous Inputs From the Hindpaw to the Control of Locomotion. I. Intact Cats

L.J.G. Bouyer, S. Rossignol
2003 Journal of Neurophysiology  
The companion paper shows on the other hand that when the same cats are spinalized, these cutaneous inputs become critical for foot placement during locomotion.  ...  The adaptive changes during walking on the incline were much reduced after denervation. Ladder walking gradually recovered within 3-7 wk.  ...  Trevor Drew for providing access to the force platforms and for help with some of the computer analyses; and thanks to Drs.  ...

Neural Substrates of Chronic Pain in the Thalamocortical Circuit

Antonio Zippo, Riccardo Storchi, Maurizio Valente, Gian Carlo Caramenti, Gabriele Biella
2011 Nature Precedings  
These works, however, give no hints on the way the neuronal brain substrates behave in the diverse CP conditions.  ...  Furthermore, unlike acute pain, CP is not necessarily sustained by inputs from the periphery, and it may even be free from any provoking causes (3).  ...  The resulting graph has many, typically small, quasi-complete subgraphs (cliques) where each node is connected to every other clique node.  ...

Relying on planewaves for the representation of wavefunctions, density, and other space-dependent quantities, with pseudopotentials or projector-augmented waves (PAWs), it is well suited for the study  ...  It then focuses on selected capabilities that might not be present in the majority of electronic structure packages either among planewave codes or, in general, treatment of strongly correlated materials  ...  In this respect, ABINIT [2] [3] [4] [5] was one of the first free licensed solid-state electronic structure packages on the market.  ...
