The readout system and the trigger algorithm implementation for the UFFO Pathfinder

2012

Since the launch of the SWIFT, Gamma-Ray Bursts (GRBs) science has been much progressed. Especially supporting many measurements of GRB events and sharing them with other telescopes by the Gamma-ray Coordinate Network (GCN) have resulted the richness of GRB events, however, only a few of GRB events have been measured within a minute after the gamma ray signal. This lack of sub-minute data limits the study for the characteristics of the UV-optical light curve of the short-hard type GRB and the fast-rising GRB. Therefore, we have developed the telescope named the Ultra-Fast Flash Observatory (UFFO) Pathfinder, to take the sub-minute data for the early photons from GRB. The UFFO Pathfinder has…

Measuring spectrally-resolved information transfer for sender- and receiver-specific frequencies

2020

AbstractInformation transfer, measured by transfer entropy, is a key component of distributed computation. It is therefore important to understand the pattern of information transfer in order to unravel the distributed computational algorithms of a system. Since in many natural systems distributed computation is thought to rely on rhythmic processes a frequency resolved measure of information transfer is highly desirable. Here, we present a novel algorithm, and its efficient implementation, to identify separately frequencies sending and receiving information in a network. Our approach relies on the invertible maximum overlap discrete wavelet transform (MODWT) for the creation of surrogate d…

Le verità prevalenti

2010

Difficile condensare in poche righe, i tanti spunti e le diverse sollecitazioni che scaturiscono dall’ultimo libro di Gian Carlo Caselli (Le due guerre. Perché l’Italia ha sconfitto il terrorismo e non la mafia, Melampo, Milano, 2009). I piani di lettura su cui si dispiega sono diversi e ciascuno apre una prospettiva da esplorare, fornisce differenti chiavi analitiche e interpretative. Quasi si trattasse di strati di sedimentazione in cui l’area del vissuto interseca gli aspetti più professionali, la sfera emotiva incrocia quella razionale. Un testo ricco, come ricca di esperienze è la vita del suo Autore che del testo costituisce la vera trama.

Comprehensive Modeling and Experimental Testing of Fault Detection and Management of a Nonredundant Fault-Tolerant VSI

2015

This paper presents an investigation and a comprehensive analysis on fault operations in a conventional three-phase voltage source inverter. After an introductory section dealing with power converter reliability and fault analysis issues in power electronics, a generalized switching function accounting for both healthy and faulty conditions and an easy and feasible method to embed fault diagnosis and reconfiguration within the control algorithm are introduced. The proposed system has simple and compact implementation. Experimental results operating both at open- and closed-loop current control, obtained using a test bench realized using a dSPACE system and the fault-tolerant inverter protot…

Towards the Development of Antitumor Vaccines: A Synthetic Conjugate of a Tumor-Associated MUC1 Glycopeptide Antigen and a Tetanus Toxin Epitope.

2000

Proliferation of cytotoxic T-cells, a prerequisite for the development of antitumor vaccines, was induced by 1, but not by its partial structures A and B. The conjugate 1 containing a tumor-associated Sialyl-TN -MUC-1 glycopeptide antigen A and a T-cell epitope B of tetanus toxin was synthesized by fragment condensation on a solid phase.

Ultreya, suseya, Santiago!” Viaggio e spazialità ne La ballata dei pellegrini

2020

Per studiare dal punto di vista della geografia culturale alcuni aspetti del pellegrinaggio a Santiago de Compostela, in Spagna, il capitolo prende in considerazione un testo letterario, il romanzo autobiografico "La ballata dei pellegrini" della scrittrice francese Edith De La Héronnière, pubblicato per la prima volta nel 1993 e tradotto in italiano nel 2004. Il romanzo racconta l’esperienza del pellegrinaggio giacobeo effettuato dall’autrice negli anni Novanta assieme a tre compagni di viaggio partendo da un cammino francese. In particolare, attraverso l’analisi di alcune parti del testo, si indagano le modalità attraverso le quali la narrazione costruisce e descrive lo spazio fisico e si…

The contribution critically and from a geographical perspective discusses the connection between propaganda comics and cartoons in the period of twentieth-century totalitarianisms. The way in which space real and symbolic is implicated through the rhetoric and dialectics of power in social economic and identity dynamics is then explored. In order to study some aspects of the pilgrimage to Santiago de Compostela from the point of view of cultural geography in Spain the chapter takes into consideration a literary text the autobiographical novel "The pilgrims' ballad" by the French writer Edith De La Héronnière first published in 1993 and translated into Italian in 2004. The novel recounts the experience of the Jacobean pilgrimage carried out by the author in the nineties together with three traveling companions starting from a French journey. In particular through the analysis of some parts of the text the ways in which the narration constructs and describes the physical and symbolic space of the pilgrimage are investigated. In this way it is possible to explore the way in which peculiar attributions of meaning inscribe the experience of pilgrimage in a symbolic universe that is both personal and collective at the same time.

Rapid and eco-friendly synthesis of graphene oxide-silica nanohybrids

2014

The increasing interest in Graphene oxide (GO) is due to many issues: the presence of both sp2-conjugated atoms and oxygen-containing functional groups provides a strong hydrophilicity and the possibility to further functionalize it with other molecules (i.e. π-π interactions covalent attachment etc.) [1]. Furthermore since the GO is biocompatible and noncytotoxic many studies have been recently focused on the development of GO-based nanodevices for bioimaging DNA detection drug delivery. Due to their low cytotoxicity and large internal surface area silica nanoparticles have been taken into account as promising material for biolabeling and drug loading/delivery. Particular consideration has recently been demonstrated for GO-silica composites because of the potentialities for electrical applications their chemical inertia and stability toward ions exposure. The possibility to combine the extraordinary properties of GO and silica offers several advantages for the realization of nanoprobes for biological applications and of biosensor [12]. The strategy for the fabrication of GO-nanosilica nanohybrids can be schematized as follows: (i) synthesis of GO by oxidizing graphite powder with the method described by Marcano et al. [3] (ii) Preparation of oxygen-loaded silica nanoparticles by thermal treatments in controlled atmosphere in order to induce high NIR emission at 1272 nm from high purity silica nanoparticles. (iii) preparation of GrO-silica nanohybrid films via rapid solvent casting in water. The nanohybrids were tested by XPS FTIR Raman analysis UV photoluminescence analysis TGA Zeta potential measurements electrical tests AFM and SEM. Several nanohybrids were prepared by combining two different typologies of GO and two different samples of silica.
