The Hamiltonian H is the generator of the dynamics of physical systems. In this respect, the energy content of a system will determine its evolution time scales. For instance, the time-energy uncertainty relation states that the time it takes for a system to evolve to an orthogonal configuration in the Hilbert space is limited by the inverse of the energy spread of the system. Analogously, the ...

This paper focuses on sovereign credit risk meaning a hot topic related to the current Eurozone crisis. In the light of the recent financial crisis, market perception of the creditworthiness of individual sovereigns has changed significantly. Before the outbreak of the financial crisis, market participants did not differentiate between credit risk born by individual states despite different lev...

An updated view of the establishment and spread of the leishmaniases in Europe is presented, mostly with respect to newly emerging and re-emerging foci and the incrimination of neglected as well as new reservoir hosts. At the same time, a concept of specific versus permissive vectors reassesses the potential role of various sandfly species in Leishmania transmission and considers the risk of in...

We report on the long term monitoring of the GINGA transient source GS 1826-238 performed with the BeppoSAX Wide Field Camera (WFC) instrument, during four different observing campaigns covering October 1996 September 1999. WFC detection of type-I bursting activity from the source ruled out its proposed Black Hole candidacy and clearly suggested the compact object related to GS 1826-238 to be a...

It is proposed to use the ”Ensembles” of particles for modeling the beams in accelerators. Each ensemble describes the longitudinal and transverse dynamics of the nonmonochromatic bunch in the six dimensional phase space, taking into account all coupling effects, coming from the relativistic relation between variation of the velocity projection and energy spread. Ensemble parameters include ave...

Abstract: The shear strength and stick-slip behavior of a rough rock joint are analyzed using the 8 complex network approach. We develop a network approach on correlation patterns of void 9 spaces of an evolvable rough fracture (crack type II). Correlation among networks properties 10 with the hydro -mechanical attributes (obtained from experimental tests) of fracture before and 11 after slip i...

In this paper we bring together two Operations Research techniques, Cutting and Packing Optimisation (CPO) and Simulation, and present a multi-methodology approach for analysing the trade-offs between loading efficiency and various important practical considerations in relation to the cargo such as its stability, fragility, or possible cross-contamination between different types of items over t...

We investigate the Mg–σ and –σ relations in a sample of 72 early-type galaxies drawn mostly from cluster and group environments using a homogeneous data-set which is well-calibrated onto the Lick/IDS system. The small intrinsic scatter in Mg at a given σ gives upper limits on the spread in age and metallicity of 49% and 32% respectively, if the spread is attributed to one quantity only and ...
