Hippocampal electrical stimulation disrupts associative learning when targeted at dentate spikes
2017
KEY POINTS Dentate spikes are fast fluctuations of hilar local-field potentials that take place during rest and are thought to reflect input arriving from the entorhinal cortex to the hippocampus. During dentate spikes, neuronal firing in hippocampal input (dentate gyrus) and output (CA1/CA3) regions is uncoupled. To date, the behavioural significance of dentate spikes is unknown. Here, we provide evidence that disrupting the dentate spike-related uncoupling of the dentate gyrus and the CA1/CA3 subregions for 1 h after training retards associative learning. We suggest dentate spikes play a significant role in memory consolidation. ABSTRACT Hippocampal electrophysiological oscillations, name…
Temperature control during Spark Plasma Sintering and application to up-scaling and complex shaping
2013
International audience; The determination and the homogeneity of the sample temperature during consolidation of powders by Spark Plasma Sintering (SPS) are addressed. Densifications were carried out in three different facilities differing by their constructors and their size. A structural transformation activated in a TiAl alloy was used as a marker of the sample temperature and finite element modeling were performed to evaluate the temperature at each point of the set-up. A good agreement between experimental and simulated data is exhibited. Alloys with identical microstructures were sintered and the homogeneity of the microstructure was better in the largest machines or when the sample wa…
Bifurcations in business profitability: An agent-based simulation of homophily in self-financing groups
2021
Abstract Formal financial institutions inadequately distribute startup capital to business ventures of ethnic minorities, women, low-educated, and young people. Self-financing groups fill this gap because in these associations agents accumulate their savings into a fund that is later used to provide loans to the members. This study builds and simulates an agent-based model that compares the profitability of businesses started by members of self-financing groups against businesses financed by commercial loans. The results indicate that—besides the self-generation of debt capital—businesses of members of self-financing groups can have higher returns due to the consolidation of social capital …
Processing conditions, microstructure and mechanical properties of hetero-nanostructured ODS FeAl alloys produced by spark plasma sintering
2013
International audience; Spark plasma sintering (SPS) has been used to sinter a milled oxide dispersion-strengthened (ODS) FeAl powder in order to prepare dense nanostructured parts. The effect of processing conditions including sintering temperature, holding time and degassing treatments on the microstructure and mechanical properties of the as-sintered materials was investigated. A hetero-nanostructure that contains nano, ultrafine and micrometric grains was confirmed to be developed whatever the processing window, due to the large temperature difference generated during the SPS process itself. The grain size distribution can be tailored by selecting a combination of sintering temperature …
Verifiche Diagnostiche nell'ex Chiesa Madre di Santa Margherita di Belice
2011
La relazione presenta in modo dettagliato gli esiti della seconda campagna di indagini diagnostiche, svolta nella fabbrica architettonica a cantiere di restauro in corso d'opera. L'obiettivo delle valutazioni non distruttive e minimamente invasive è valutare la corretta esecuzione degli interventi attraverso il confronto tra la diagnosi preliminare e quella post-intervento. The report presents in detail the results of the second campaign of diagnostic investigations, carried out in the architectural restoration site. The goal of minimally invasive and non-destructive evaluation is to assess the proper execution of consolidation through the comparison between the preliminary and post-interve…

Indagini diagnostiche nella chiesa di Santa Maria delle Stelle a Comiso
2012
La relazione riporta dettagliatamente gli esiti di una campagna d'indagini non distruttive e minimamente invasive svolte nella chiesa madre di Santa Maria delle Stelle a Comiso, su incarico della Soprintendenza ai Beni Culturali e Ambientali della Provincia di Ragusa. Le indagini diagnostiche comprendono la termografia all'infrarosso, l'indagine radar, l'indagine ultrasonica, le ispezioni endoscopiche, il controllo dell'umidità e le verifiche statiche. Technical Report regarding the outcome of a campaign of minimally invasive and non-destructive surveys conducted in the mother church of Santa Maria delle Stelle in Comiso (RG) on assignment by the Superintendence of Cultural Heritage and Env…
Indagini Diagnostiche nell'Ex Chiesa Madre di Santa Margherita di Belice
2010
La relazione presenta in modo dettagliato gli esiti di una campagna d'indagini diagnostiche non distruttive e minimamente invasive svolte nella ex chiesa madre di Santa Margherita di Belice per supportare, in particolare, lo studio delle murature e della decorazione a stucco. Le indagini hanno supportato l'elaborazione del progetto definitivo e del progetto esecutivo del restauro, come prescritto dalla normativa di riferimento. The report presents in detail the results of a campaign of non-destructive and minimally invasive diagnostic surveys performed in the former mother church of Santa Margherita di Belice to support, in particular, the study of masonry and stucco decoration. The investi…
