We apply the path-integral formalism to compute the anomalies in general orbifold gauge theories (including possible non-trivial Scherk-Schwarz boundary conditions) where a gauge group G is broken down to subgroups H f at the fixed points y = y f. Bulk and localized anomalies, proportional to δ(y − y f), do generically appear from matter propagating in the bulk. The anomaly zero-mode that survi...

Bivariate linear mixed models are useful when analyzing longitudinal data of two associated markers. In this paper, we present a bivariate linear mixed model including random effects or first-order auto-regressive process and independent measurement error for both markers. Codes and tricks to fit these models using SAS Proc MIXED are provided. Limitations of this program are discussed and an ex...

A model based on an anomalous Abelian symmetry U(1)1 × U(1)2 is presented. This symmetry is responsible for both supersymmetry breaking and fermion mass generation. Quark and squark mass matrices are aligned to prevent large flavor-changing neutral current and CP-violation. E-mail address: [email protected] 1. Supersymmetry is a good candidate for a theory beyond the standard model, and s...

−ν∇u+ u.∇u+∇p = f ∇ · u = 0 which are taken to hold in some domain Ω ⊂ IR together with appropriate boundary conditions. We concentrate on the steady state equations; timedependent problems are essentially easier in the context of iterative methods. We will make some comment on this later. The numerical results we present here come from mixed finite element approximation though the techniques a...

In this paper we undertake an acoustic analysis of dental and alveolar segments in Mapudungun, an indigenous language of Chile. We calculate locus equations for dental and alveolar segment pairs of different manners. We find that dentals differ from alveolars of the corresponding manner in lowering the onset F2 of following vowels. We validate these results by means of a linear mixed model anal...

This paper deals with different chain graph interpretations and the relations between them in terms of representable independence models. Specifically, we study the Lauritzen-Wermuth-Frydenberg, Andersson-Madigan-Pearlman and multivariate regression interpretations and present the necessary and sufficient conditions for when a chain graph of one interpretation can be perfectly translated into a...

Topic variance has a greater effect on performances than system variance but it cannot be controlled by system developers who can only try to cope with it. On the other hand, system variance is important on its own, since it is what system developers may affect directly by changing system components and it determines the differences among systems. In this paper, we face the problem of studying ...
