Single Event Upsets Induced by Direct Ionization from Low-Energy Protons in Floating Gate Cells
2017
Floating gate cells in advanced NAND Flash memories, with single-level and multi-level cell architecture, were exposed to low-energy proton beams. The first experimental evidence of single event upsets by proton direct ionization in floating gate cells is reported. The dependence of the error rate versus proton energy is analyzed in a wide energy range. Proton direct ionization events are studied and energy loss in the overlayers is discussed. The threshold LET for floating gate errors in multi-level and single-level cell devices is modeled and technology scaling trends are analyzed, also discussing the impact of the particle track size. peerReviewed
Rac1-Regulated Endothelial Radiation Response Stimulates Extravasation and Metastasis That Can Be Blocked by HMG-CoA Reductase Inhibitors
2011
Radiotherapy (RT) plays a key role in cancer treatment. Although the benefit of ionizing radiation (IR) is well established, some findings raise the possibility that irradiation of the primary tumor not only triggers a killing response but also increases the metastatic potential of surviving tumor cells. Here we addressed the question of whether irradiation of normal cells outside of the primary tumor augments metastasis by stimulating the extravasation of circulating tumor cells. We show that IR exposure of human endothelial cells (EC), tumor cells (TC) or both increases TC-EC adhesion in vitro. IR-stimulated TC-EC adhesion was blocked by the HMG-CoA reductase inhibitor lovastatin. Glycyrr…
S’aimer à l’heure du numérique : la relation conjugale à l’épreuve de l’hyperconnectivité
2014
L’introduction des nouveaux objets connectés (NOC) dans les foyers vient réinterroger la relation conjugale. Avec les objets nomades, le couple doit faire face à un individualisme connecté. Ils amplifient notamment la privatisation des territoires dans l’espace domestique semblant de ce fait affecter la conversation conjugale. À travers notre enquête, nous avons constaté que les technologies de l’information et de la communication (TIC) peuvent certes avoir un impact négatif sur la relation de couple, mais peuvent a contrario venir renforcer la relation en donnant entre autres une nouvelle place à l’écrit dans la communication conjugale. Des différences apparaissent toutefois selon les type…
¿Quién está buscando su mejor versión? Coaching y psicología deportiva en el proceso de terapeutización de (y desde) el golf
2020
This article asks about the expansion of psychological, therapeutic and self-enhancement ethos through the networks and devices that configures middle and upper-middle classes, and about the ways in which this process is singled out starting from the encounter between coaching and psychology paradigms with golf fans, in contemporary Argentina. The empirical materials that support the analysis have been ethnographically produced from the interaction with golf players and coaches.
Charge Transport Mechanisms in Heavy-Ion Driven Leakage Current in Silicon Carbide Schottky Power Diodes
2016
Under heavy-ion exposure at sufficiently high reverse bias voltages silicon carbide (SiC) Schottky diodes are observed to exhibit gradual increases in leakage current with increasing ion fluence. Heavy-ion exposure alters the overall reverse current-voltage characteristics of these diodes, leaving the forward characteristics practically unchanged. This paper discusses the charge transport mechanisms in the heavy-ion damaged SiC Schottky diodes. A macro model, describing the reverse current-voltage characteristics in the degraded SiC Schottky diodes is proposed. peerReviewed
Sistemi di comunicazione e dispositivi di interfaccia per l'integrazione della generazione distribuita nelle smart grids
2014
L'integrazione della generazione distribuita (GD) nelle reti elettriche di distribuzione a media e bassa tensione uno degli elementi chiave per il pieno sfruttamento delle fonti energetiche rinnovabili (FER). Ci implica un ripensamento della gestione e del controllo delle reti elettriche , che devono passare da sistemi " passivi ", con flussi di potenza unidirezionali e un numero limitato di funzioni di monitoraggio e automazione, a reti attive e intelligenti (Òsmart gridsÒ). In tali sistemi, i flussi di potenza possono essere bi-direzionali e, se non correttamente gestiti, possono causare situazioni critiche, quali ad es. problemi di stabilit e di controllo della rete o funzionamento i…
Towards Seamless IoT Device-Edge-Cloud Continuum:
2021
In this paper we revisit a taxonomy of client-side IoT software architectures that we presented a few years ago. We note that the emergence of inexpensive AI/ML hardware and new communication technologies are broadening the architectural options for IoT devices even further. These options can have a significant impact on the overall end-to-end architecture and topology of IoT systems, e.g., in determining how much computation can be performed on the edge of the network. We study the implications of the IoT device architecture choices in light of the new observations, as well as make some new predictions about future directions. Additionally, we make a case for isomorphic IoT systems in whic…
The Dawn of the Human-Machine Era: A forecast of new and emerging language technologies
2021
New language technologies are coming, thanks to the huge and competing private investment fuelling rapid progress; we can either understand and foresee their effects, or be taken by surprise and spend our time trying to catch up. This report scketches out some transformative new technologies that are likely to fundamentally change our use of language. Some of these may feel unrealistically futuristic or far-fetched, but a central purpose of this report - and the wider LITHME network - is to illustrate that these are mostly just the logical development and maturation of technologies currently in prototype. But will everyone benefit from all these shiny new gadgets? Throughout this report we …
On the structural optimization in presence of base isolating devices
2012
The minimum volume design of plane frames constituted by elastic perfectly plastic material and subjected to appropriate combinations of fixed, cyclic and dynamic loads is studied. The influence on the design, in terms of cost (volume) and behavioural features, of seismic protecting devices is particularly focused. The considered protecting device is a lead rubber bearing base isolation system. Two optimal design problem formulations are proposed for the structure with or without the protecting device, both based on the so-called statical approach. The minimum volume frame is reached accounting for three different resistance limits: the purely elastic limit, the (elastic) shakedown limit an…
