We review the quark-meson coupling model, in which the quark degrees of freedom are explicitly involved to describe the properties of not only nuclear matter but also finite nuclei. Then, we present the electric and magnetic form factors for the proton bound in specific orbits for several closed-shell nuclei. Key-words: quark degrees of freedom, finite nuclei, electromagnetic form factors

We consider the effective potential in three-dimensional models with O(N) symmetry. For generic values of N , and in particular for the physically interesting cases N = 0, 1, 2, 3, we determine the six-point and eight-point renormalized coupling constants which parametrize its small-field expansion. These estimates are obtained from the analysis of their ǫ-expansion, taking into account the exa...

We study the dynamics of identical leaky integrate-and-fire neurons with symmetric non-local coupling. Upon varying control parameters (coupling strength, coupling range, refractory period) we investigate the system's behaviour and highlight the formation of chimera states. We show that the introduction of a refractory period enlarges the parameter region where chimera states appear and affects...

extended interaction oscillators (eio) are vacuum electronic sources of microwave, millimeter-wave and terahertz radiations. in this paper, eio is investigated by using a circuit model. the value of the coupling element in the model is evaluated from the near band-edge dispersion characteristics of the rf structure. the end external loading of the interaction structure is equivalently modeled b...

In practice dependency management often suffers from labor intensity and complexity in creating and maintaining the dependency relations. Our method targets projects, where developers are geographically distributed and a wide range of tools is used. A conceptual domain model is used to inter-relate the development objects and to automate dependency link discovery. The proposed method is based o...

For continuum 1=r 2 Ising models, we prove that the critical value of the long range coupling constant (inverse temperature), above which an ordered phase occurs (for strong short range cutoo), is exactly one. This leads to a proof of the existence of an ordered phase with slow decay of correlations. Our arguments involve comparisons between continuum and discrete Ising models, including (quenc...

We describe UCFTAC, a trading agent based on control based principles, which has participated with success in 2006 Supply Chain Management Trading Agent Competition. The UCFTAC approach uses a sophisticated procurement strategy and an aggressive price control feature. It achieved competitive results in the TAC-SCM 2006 qualification round. Our design consists of a loosely coupled set of agent-m...

Carrier-induced ferromagnetism has been observed in several (III,Mn)V semiconductors. We review the theoretical picture of these ferromagnetic semiconductors that emerges from a model with kinetic-exchange coupling between localized Mn spins and valence-band carriers. We discuss the applicability of this model, the validity of a mean-field approximation for its interaction term widely used in t...

The central thesis explored in this paper is that parallel model checking is easily achieved through compositional methods. This may strike the reader as being self-evident. Nevertheless, it does not appear to have been considered before. The justification comes from the following observations: (1) the efficacy of a parallel program is inversely proportional to the amount of synchronization and...
