A production mechanism of highly excited nuclei formed in violent collisions in the Fermi energy domain is investigated. The collision of two nuclei is decomposed into several stages which are treated separately. Simplified exciton concept is used for the description of pre-equilibrium emission. A modified spectator-participant scenario is used where motion along classical Coulomb trajectories ...

In this work improvements to the application of the Gross equation to nuclear systems are tested. In particular we evaluate the two pion exchange diagrams, including the crossed-box diagram, using models developed within the spectator-on-mass-shell covariant formalism. We found that the form factors used in these models induce spurious contributions that violate the unitary cut requirement. We ...

A new Digital Terrestrial Television service based on transmission and visualization of 3D images is presented. This service has been designed to be suitable for domestic users without relevant increase of the final cost for the spectator, being the production of the programs what is modified to generate adequate 3D TV signals. The systems that make possible the implementation of the service ha...

We estimate a model capturing influences on attendance in British horseracing. A fixed effects regression is employed analysing data containing information attendances at 23,999 race-days (2001–2018). The patterns of demand are similar to those found for other sports, example, higher weekends and warmer months sensitive the quality racing. Further, falls when races have compete with some televi...

What explains the ambition to get rich? Adam Smith is clear that commercial ambition, passionate desire for great wealth, not simply a satisfy one’s material needs. His argument on what underlies it, however, obvious. I review three possibilities suggested by Smith’s work and scholarly literature—vanity, love of system, tranquility—and conclude none them captures underlying motive ambition. Ins...

Abstract Motivated by the result of Planck+BICEP/Keck recently released, we investigate consistency multi-field inflation models in terms spectral index n s and tensor-to-scalar ratio r . In this study, focus on double-inflaton with without a spectator field. We find that inflaton quadratic potential can become viable when three fields specific hierarchical mass spectrum are realized such two a...
