Choline PET/CT Features to Predict Survival Outcome in High Risk Prostate Cancer Restaging: A Preliminary Machine-Learning Radiomics Study

2020

Background Radiomic features are increasingly utilized to evaluate tumor heterogeneity in PET imaging but to date its role has not been investigated for Cho-PET in prostate cancer. The potential application of radiomics features analysis using a machine-learning radiomics algorithm was evaluated to select 18F-Cho PET/CT imaging features to predict disease progression in PCa. Methods We retrospectively analyzed high-risk PCa patients who underwent restaging 18F-Cho PET/CT from November 2013 to May 2018. 18F-Cho PET/CT studies and related structures containing volumetric segmentations were imported in the "CGITA" toolbox to extract imaging features from each lesion. A Machine-learning model h…

Demonstrating dynamics to support learning from complex animations

2016

International audience; This round table will explore the potential of learner demonstrations to be a more effective alternative support strategy than self-generated drawing for improving learning from complex animations. Discussion will be stimulated by three presentations reporting recent work of the EARLI Center for Innovative Research ‘Drawing for Learning from Animation’ and key focus questions arising from that research. The presentations will cover the processing challenges posed to learners by requiring them to self-generated drawings from complex animations, how these challenges may be ameliorated by instead having learners perform demonstrations with manipulable models, and empiri…

Viva voce: Voice and Voicelessness among Twelfth-Century Clerics

2015

Writing in his Summa on Gratian’s Decretum1 toward 1164, canonist Rufinus of Bologna2 evokes criminal prelates, saying, “vocem accusandi, reprehendi, docendi non habent” (they do not have a voice to accuse, punish, teach).3 Should this enumeration be understood as a commonplace statement about three possible functions of the voice, or should we suspect a set of deeper associations? Is Rufinus’s use of the word “voice” simply an alternative to other rhetorical or stylistic possibilities—such as the word “word” in particular—or is it truly a deliberate choice on the part of the canonist?

Hablemos de ángeles calvos, demonios pelones y figuras grotescas en la escultura barroca gallega

2014

ABSTRACT: The unusual bald angels depicted in the interior of the sounding board of the pulpit on the Gospel side of the Monastery of San Martiño Pinario in Santiago de Compostela are the starting point to undertake an iconographical study of the representation of demons in Galician Baroque sculpture, primarily in that found in Santiago de Compostela. In this analysis I go beyond the mere identification of its characteristic attributes in order to try to reconstruct the contents that they could communicate within their cultural context. In order to do so, I turn to sources derived from sacred and profane literature, as well as to Neostoicism as the prevailing trend in Spanish Catholicism of…

Preliminary Thermo-Mechanical Design of the Once Through Steam Generator and Molten Salt Intermediate Heat Exchanger for EU DEMO

2020

The European DEMOnstration power plant (DEMO) is considered to be the nearest-term fusion reactor capable of producing several hundred MWs of net electricity, operating with a closed tritium fuel-cycle (achieving the tritium self-sufficiency), and qualifing technological solutions for a fusion power plant with different breeding blanket (BB) concepts that are under investigation. The BB is a key component for the development of the DEMO plant design and, in particular, of those systems having the responsibility to remove the plasma-generated thermal power and its conversion in the electrical energy. This study deals with the preliminary thermo-mechanical design of the heat exchangers and st…

Overview of the HCPB Research Activities in EUROfusion

2018

In the framework of the EUROfusion’s Power Plant Physics and Technology, the working package breeding blanket (BB) aims at investigating four different BB concepts for an EU demonstration fusion reactor (DEMO). One of these concepts is the helium-cooled pebble bed (HCPB) BB, which is based on the use of pebble beds of lithiated ternary compounds and Be or beryllides as tritium breeder and multiplier materials, respectively, EUROFER97 as structural steel and He as coolant. This paper aims at giving an overview of the EU HCPB BB Research and Development (R&D) being developed at KIT, in collaboration with Wigner-RCP, BUTE-INT, and CIEMAT. The paper gives an outline of the HCPB BB design evolut…

Total absorption spectroscopy study of the β decay of Br86 and Rb91

2017

The beta decays of 86Br and 91Rb have been studied using the total absorption spectroscopy technique. The radioactive nuclei were produced at the IGISOL facility in Jyvaskyla and further purified using the JYFLTRAP. 86Br and 91Rb are considered high priority contributors to the decay heat in reactors. In addition 91Rb was used as a normalization point in direct measurements of mean gamma energies released in the beta decay of fission products by Rudstam et al. assuming that this decay was well known from high-resolution measurements. Our results shows that both decays were suffering from the Pandemonium effect and that the results of Rudstam et al. should be renormalized.

Measurement of fission products β decay properties using a total absorption spectrometer

2013

In a nuclear reactor, the decay of fission fragments is at the origin of decay heat and antineutrino flux. These quantities are not well known while they are very important for reactor safety and for our understanding of neutrino physics. One reason for the discrepancies observed in the estimation of the decay heat and antineutrinos flux coming from reactors could be linked with the Pandemonium effect. New measurements have been performed at the JYFL facility of Jyvaskyla with a Total Absorption Spectrometer (TAS) in order to circumvent this effect. An overview of the TAS technique and first results from the 2009 measurement campaign will be presented. © Owned by the authors, published by E…
