www.nexusmagazine.com NEXUS • 1 Magnesium is nothing short of a miracle mineral in its healing effect on a wide range of diseases as well as in its ability to rejuvenate the aging body. We know that it is essential for many enzyme reactions, especially in regard to cellular energy production, for the health of the brain and nervous system and also for healthy teeth and bones. However, it may co...

We have proposed that protein kinase C, an enzyme critical to cell regulation of growth, secretion and differentiation, is a part of a sequence of molecular events that underlie learning and memory. Electrophysiological, biochemical and neuro-imaging methods have been employed to show that the enzyme changes its distribution as a result of memory storage within the neural networks that are nece...

Information infrastructure building efforts have entered both research literature and the practice of utilizing information and communication technology (ICT) in organizations as well as in our everyday life. The concept of infrastructuring has also challenged the traditional, project-based assumptions of information systems (IS) development. This study will explore infrastructuring within the ...

Software implemented fault injection techniques (SWIFI) enable emulation of hardware and software faults. This emulation can be based on debugging mechanisms of general purpose processors [1] or in special debugging ports of embedded processors [2]. A well-known drawback of existing SWIFI tools rely on the temporal overhead introduced in the target system. This overhead is a problem when valida...

The Algerian economy is an example of a high level of rentierism, while the Egyptian economy shows a low/moderate level of rentierism. The ARDL bounds test approach was used upon annual time series data from 1965 to 2010. The results suggest cointegration for both countries. Bi-causality between energy consumption and growth in the long run was found. For Algeria there is a reversed (negative) ...

Preface 1 Sonderforschungsbereich Nexus is a Center of Excellence that has been established at Universität Stuttgart in January 2003. This interdisciplinary research center, which is funded by Deutsche Forschungsgemeinschaft (DFG), currently involves more than 30 researchers from various fields, including computer science, electrical engineering , civil engineering, mechanical engineering, and ...

We use the term ubiquitous supercomputing to refer to systems that integrate lowand mid-range computing systems, advanced networks, and remote highend computers with the goal of enhancing the computational power accessible from local environments. Such systems promise to enable new applications in areas as diverse as smart instruments and collaborative environments. However, they also demand to...

It is very plausible that confinement in QCD comes from linking of Wilson loops to finite-thickness vortices with magnetic fluxes corresponding to the center of the gauge group. The vortices are solitons of a gauge-invariant QCD action representing the generation of gluon mass. There are a number of other solitonic states of this action. We discuss here what we call nexus solitons, in which for...
