The mutable nature of particle-core excitations with spin in the one-valence-proton nucleus Sb-133

The gamma-ray decay of excited states of the one-valence-proton nucleus Sb-133 has been studied using cold-neutron induced fission of U-235 and Pu-241 targets, during the EXILL campaign at the ILL reactor in Grenoble. By using a highly efficient HPGe array, coincidences between gamma-rays prompt with the fission event and those delayed up to several tens of microseconds were investigated, allowing to observe, for the first time, high-spin excited states above the 16.6 mu s isomer. Lifetimes analysis, performed by fast-timing techniques with LaBr3(Ce) scintillators, revealed a difference of almost two orders of magnitude in B(M1) strength for transitions between positive-parity medium-spin yrast states. The data are interpreted by a newly developed microscopic model which takes into account couplings between core excitations (both collective and non-collective) of the doubly magic nucleus Sn-132 and the valence proton, using Skyrme effective interaction in a consistent way. The results point to a fast change in the nature of particle-core excitations with increasing spin. (C) 2016 The Authors. Published by Elsevier B.V.

La adaptación teatral de textos narrativos en España, 1972-2012

Novel or story adaptations and also dramatic texts versions, that need to be translated and updated to modern audiences are quite frequent in today`s theatre. This study aims to show the state of contemporary stage adaptation of narrative texts and, specifically, its evolution in Spain in the last forty years (1972-2012). To do this, I have tried to gather, first, all the terminology associated with the concept of stage adaptation: version, dramaturgy, rewriting, translation, interpretation, updating and consolidation. The theoretical part of the work begins with the various definitions of the concept of dramatization. All the positions reflected by theorists and specialists in the field come together when explaining the term adaptation or theatre version: the intervention on the original text is based on the transformation or change, radical or superficial, for its effective representation in the theatre. In contemporary times, the concept of adaptation applies to any kind of intervention, from the translation of the original (and rewriting) to the dramaturgical work involved in creating a new sense. In turn, any theatre adaptation requires a dramaturgical operation and supports all possible moves: reorganization of the story, breakage, reduced characters, dramatic concentration, incorporation of foreign texts, installation and collage, changes to the plot, etc. Although there is no definitive model for the theatre adaptation of works, several authors and theatrical theorists propose guidelines and types of adaptation to the transformation of a work into another or one genre into a different one; and regarding narrative texts, provide criteria for interpreting the original text. The issue for many authors is the danger of modifying or betraying the sense or the form of the original text, considering it as simple material for the play. Finally, it follows that there is affinity of thought among authors finding that there is no differentiation between adaptation and version: both terms refer to the same in the theatrical event and are also terms used equally for the countless film adaptations of novels and plays...

A Methodology to Emulate Single Event Upsets in Flip-Flops using FPGAs through Partial Reconfiguration and Instrumentation

This paper presents a methodology to emulate Single Event Upsets (SEUs) in FPGA flip-flops (FFs). Since the content of a FF is not modifiable through the FPGA configuration memory bits, a dedicated design is required for fault injection in the FFs. The method proposed in this paper is a hybrid approach that combines FPGA partial reconfiguration and extra logic added to the circuit under test, without modifying its operation. This approach has been integrated into a fault-injection platform, named NESSY (Non intrusive ErrorS injection SYstem), developed by our research group. Finally, this paper includes results on a Virtex-5 FPGA demonstrating the validity of the method on the ITC’99 benchmark set and a Feed-Forward Equalization (FFE) filter. In comparison with other approaches in the literature, this methodology reduces the resource consumption introduced to carry out the fault injection in FFs, at the cost of adding very little time overhead (1.6 �μs per fault).
