Remarks on the Gribov Problem in Direct Maximal Center Gauge [PDF]

, 2001
We review the equivalence of maximal center gauge fixing to the problem of finding the best fit, to a given lattice gauge field, by a thin vortex configuration. This fit is necessarily worst at the location of P-plaquettes.

In Search of the Neurobiological Substrates for Social Playfulness in Mammalian Brains

, 2011
Play behavior is a fundamental and intrinsic neurobehavioral process in the mammalian brain. Using rough-and-tumble play in the juvenile rat as a model system to study mammalian playfulness, some of the relevant neurobiological substrates for this ...

Multicriteria Evaluation of Managerial Competences: An Application of the Dominance Principle and the Rough Set Theory

Foundations of Computing and Decision Sciences, 2014
This study demonstrates an analysis of executives based on their management competences. The aim of the study is to identify those executives that show a greater strategic alignment with the guidelines set by an organization.

Effects of surface structure deformation on static friction at fractal interfaces

, 2013
The evolution of fractal surface structures with flattening of asperities was investigated using isotropically roughened aluminium surfaces loaded in compression. It was found that asperity amplitude, mean roughness and fractal dimension decrease through

Ant-based extraction of rules in simple decision systems over ontological graphs

International Journal of Applied Mathematics and Computer Science, 2015
In the paper, the problem of extraction of complex decision rules in simple decision systems over ontological graphs is considered. The extracted rules are consistent with the dominance principle similar to that applied in the dominancebased rough set ...

Allocation Reductions in Inconsistent Decision Tables Based on Dominance Relations

Fuzzy Information and Engineering, 2015
In recent years, many methods have been proposed in order to deal with inconsistent information systems based on indiscernibility relations in rough set theory. However, a little attention has been paid to inconsistent ordered decision tables.

Local Chirality of Low-Lying Dirac Eigenmodes and the Instanton Liquid Model [PDF]

, 2002
The reasons for using low-lying Dirac eigenmodes to probe the local structure of topological charge fluctuations in QCD are discussed, and it is pointed out that the qualitative double-peaked behavior of the local chiral orientation probability ...

Dynamic Knowledge Update Using Three-Way Decisions in Dominance-Based Rough Sets Approach While the Object Set Varies

International Journal of Computational Intelligence Systems
Dominance-based rough set approach is the extension of classical Pawlak rough set theories and methodologies, in which the information with preference-ordered relation on the domain of attribute value is fully considered.

A consistency check for Renormalons in Lattice Gauge Theory: beta^(-10) contributions to the SU(3) plaquette [PDF]

, 2000
We compute the perturbative expansion of the Lattice SU(3) plaquette to beta^(-10) order. The result is found to be consistent both with the expected renormalon behaviour and with finite size effects on top of that.Comment: 15 pages, 5 colour eps figures.
