We present rigorous results concerning the existence and stability of limit cycles in a macroscopic model of neuronal activity. The specific model we consider is developed from the Ki set methodology, popularized by Walter Freeman. In particular we focus on a specific reduction of the KII sets, denoted RKII sets. We analyse the unfolding of supercritical Hopf bifurcations via consideration of the normal forms and centre manifold reductions. Subsequently we analyse the global stability of limit cycles on a region of parameter space and this is achieved by applying a new methodology termed Global Analysis of Piecewise Linear Systems. The analysis presented may also be used to consider coupled systems of this type. A number of macroscopic mean-field approaches to modelling human EEG may be considered as coupled RKII networks. Hence developing a theoretical understanding of the onset of oscillations in models of this type has important implications in clinical neuroscience, as limit cycle oscillations have been demonstrated to be critical in the onset of certain types of epilepsy.

The aim of the study was to investigate the relationship between working memory, phonological awareness and developing language skills in a population of children growing up in a multilingual context involving the three languages of Luxembourgish, German, and French. A sample of 122 children from Luxembourg aged 5 to 7 years participated in the study, completing assessments of phonological short-term memory, complex working memory, phonological awareness, native and foreign vocabulary knowledge, language comprehension and reading. The data were best characterized by a model of working memory that consisted of two related but separable components - corresponding to phonological short-term memory and the central executive - that were distinct from phonological awareness. Language abilities in both the native and foreign languages were more strongly associated with phonological short-term memory than other factors in the model. The findings lend strong support to the proposal that vocabulary learning in particular is mediated, in part at least, by phonological short-term memory. [less ▲]

This research investigated the hypothesis that working memory skills are independent of environmental factors such as socio-economic or cultural background. Study 1: Twenty Brazilian children aged 6 and 7 years from low socio-economic status families were evaluated on measures of working memory (verbal short-term memory and verbal complex span, taken form the AWMA: Automated Working Memory Assessment) and of vocabulary (expressive and receptive). They were compared with typically developing Brazilian children from the same region, matched on age, sex, and nonverbal ability from families of higher socio-economic status. Children from the low socioeconomic status group obtained significantly lower scores on the vocabulary tests but not on the verbal short-term memory measures, compared to their peers from a higher socio-economical background. Both groups differed on one of the two complex span measures - counting recall - but performed equally well on backwards digit recall. The results indicate that tests of verbal short-term memory and also backwards digit recall provide measures of cognitive abilities that are not biased by the quality of the child's socio-economical background. Study 2: The Brazilian children were also compared to a population of Portuguese- speaking, immigrant children growing up in Luxembourg, evaluated on the same measures. Results will specify whether or not, in addition to being independent of socioeconomic background, verbal short-term memory and backwards digit recall are also free of cultural bias. As these measures are also highly sensitive to language ability, they may provide useful methods for diagnosing language disorder that are independent of environmental opportunity. [less ▲]

„bimuzine“ ist das Ergebnis einer engen Zusammenarbeit zwischen den mehrsprachigen Universitäten Bozen und Luxemburg. This project has been conducted by students from both universities. Pendant leurs rencontres ils ont discuté les différents aspects du plurilinguisme non seulement d'un point de vue linguistique. Ma hanno tentato di esplorare e di sperimentare altri approcci a questo tema riunendo riflessioni teoriche e momenti di gioco. Das Projekt wird im Rahmen der Tagung "BiMU" vorgestellt, die vom 20. bis 22. September 2007 stattfindet. Gli organizzatori sostengono "bimuzine" in tutti i modi e sperano che possa dare uno spunto per ulteriori riflessioni e anche per divertirsi con le lingue. [less ▲]

Prediction of jack-up leg penetration requires assesment of uncertainties in calculation models and their input parameter values, including quality and extent of site investigation information. Commonly, uncertainy assesment is achieved by sensitivity analysis. This paper presents a probabilistic approach for a more accurate prediction of jack-up leg penetration behaviour, as an add-on for conventional Society of Naval Architects and Marine Engineers (SNAME) calculation models....

The hydraulic conductivity, which is among other parameters, needed to predict time-dependant settlement, can be estimated using a piezocone dissipation test. This test is commonly used together with cone penetration tests (CPTs), soil borings and laboratory tests in foundation site investigations. The piezocone dissipation test is based on the fact that the rate of decay of the large excess pore water pressures generated during penetration of the piezocone through saturated clays and silts depends on the hydraulic conductivity of the material. However, interpretation of the dissipation curve is often problematic as existing methods of analysis assume a continuous decrease of pore pressure with time, whereas actual dissipation curves often exhibit non-standard behavior, the interpretation of which is more complex. This paper presents a new method of interpretation that can be used to estimate the hydraulic conductivity regardless of the shape of the dissipation curve. Examples of results using the new analysis method are compared with results obtained using laboratory oedometer testing. [less ▲]
