The phenomenological theory of elastic–plastic response is reconsidered in the light of recent opinion regarding the constitutive character of the constituent elastic and plastic deformations. The primary role of dissipation in the physics of plastic evolution is emphasized and shown to lead to the clarification of a number of open questions. Particular attention is given to the invariance prop...

Kl3 and πe3 transition form factors are calculated as an application of DysonSchwinger equations. The role of nonanalytic contributions to the quark–W-boson vertex is elucidated. A one-parameter model for this vertex provides a uniformly good description of these transitions, including the value of the scalar form factor of the kaon at the Callan-Treiman point. The Kl3 form factors, f K ± , are...

We present Constituent Grammatical Evolution (CGE), a new evolutionary automatic programming algorithm that extends the standard Grammatical Evolution algorithm by incorporating the concepts of constituent genes and conditional behaviour-switching. CGE builds from elementary and more complex building blocks a control program which dictates the behaviour of an agent and it is applicable to the c...

It has been postulated that the prevalence of atopic diseases and their increase over time are associated with regional differences in diet and trends. The results of an ecological correlation study comparing the mean daily intake of selected dietary constituents and the prevalence of allergic sensitization in adults in Europe is presented. Prevalence data from the European Community Respirator...

Starting from the observation that colour charge is only well defined on gauge invariant states, we construct perturbatively gauge invariant, dynamical dressings for individual quarks. Explicit calculations show that an infra-red finite mass-shell renormalisation of the gauge invariant, dressed propagator is possible and, further, that operator product effects, which generate a running mass, ma...

In Optimality Theory (OT), recent work has been exploring the idea that the order of constituents in syntax is determined by alignment constraints, developed within the theory of Generalized Alignment (see McCarthy and Prince (1993)). Costa (1998) and Samek-Lodovici (1998) present general overviews, and both have specifically argued that OT analyses are superior to proposals expressed in terms ...

A number of coordinate constructions in natural languages conjoin sequences which do not appear to correspond to syntactic constituents in the traditional sense. One striking instance of the phenomenon is afforded by the "gapping" construction of English, of which the following sentence is a simple example: (1) Harry eats beans, and Fred, potatoes Since all theories agree that coordination must...

Dyson-Schwinger equations furnish a Poincaré covariant framework within which to study hadrons. A particular feature is the existence of a nonperturbative, symmetry preserving truncation that enables the proof of exact results. Key to the DSE’s efficacious application is their expression of the materially important momentumdependent dressing of parton propagators at infrared length-scales, whic...

This report describes a semi-physical model for the dimensional stability properties (i.e. curl) of the carton board produced at AssiDomän Frövi, Sweden. The main equations are based on classical lamination theory of composite materials, and each constituent ply is considered as a macroscopic homogeneous, elastic medium. The model used data from February to June 2001, and show a general agreeme...
