From microscopic to macroscopic description of Josephson dynamics in one-dimensional arrays of weakly-coupled superconducting islands

2015

Abstract By starting from a microscopic quantum mechanical description of Josephson dynamics of a one-dimensional array of N coupled superconductors, we obtain a set of linear differential equations for the system order parameter and for additional macroscopic physical quantities. With opportune considerations, we adapt this description to two coupled superconductors, obtaining the celebrated Feynman model for Josephson junctions. These results confirm the correspondence between the microscopic picture and the semi-classical Ohta’s model adopted in describing the superconducting phase dynamics in multi-barrier Josephson junctions.

Experimental Study of the Fluctuation-Governed Resistive State in Quasi-One-Dimensional Superconductors

2011

Physical properties of quasi-one-dimensional superconducting channels (nanowires) can differ significantly from those of bulk superconductors. The reason behind is the impact of thermal and quantum fluctuations. In the particular case of resistive measurements the fluctuations may significantly broaden the superconducting transition R(T). Here we review the activities in the field with main emphasis on experiment, while brief theoretical background is also presented.

Il ruolo del white paper sulle offerte al pubblico di cripto-attività alla luce della proposta MiCA

2022

La proposta MiCA, nel regolare il white paper sulle offerte di crypto-assets, sembra tenere in considerazione i benefici e i limiti dei sistemi di voluntary e di mandatory disclosure, non optando integralmente né per il primo, né per il secondo. In quest’ottica, se può condividersi l’approccio regolamentare diretto a graduare, a seconda della tipologia di token offerto, sia il contenuto che l’assoggettamento del documento a mera notifica o ad approvazione ex ante da parte dell’Autorità competente, dubbi sorgono in ordine all’indistinta allocazione dell’onere della prova in capo all’oblato, nei casi di violazione della disciplina del relativo white paper.

The MiCa proposal in the regular white paper on crypto-assets offerings seems to take into account the benefits and limitations of voluntary and mandatory disclosure systems not opting for either the former or the latter in full. On one hand one can agree with the regulatory approach aimed at adapting the content of the white paper to the type of token offered and at making the white paper either subject to mere notification or to the approval by the competent Authority depending on the asset offered. On the other hand doubts arise on the indistinct allocation of the burden of proof to the user in case of infringement of the relevant white paper framework.Settore IUS/04 - Diritto Commerciale

La recente riforma della disciplina italiana del subappalto nella prospettiva del bid rigging

2023

L’articolo analizza in chiave critica la disciplina nazionale del subappalto nell’ambito delle gare pubbliche, così come recentemente riformata a seguito di diversi interventi normativi in ottemperanza alla procedura d’infrazione avviata dalla Commissione UE. Stando alla tesi dell’A., l’attuale quadro normativo – caratterizzato dalla quasi totale eliminazione delle limitazioni previgenti (probabilmente anche spingendosi oltre ciò che la Commissione UE ha richiesto) – difetta nel trovare un equo bilanciamento tra il principio della massima partecipazione alla gara, da un lato, e l’esigenza di prevenire e svelare potenziali condotte collusive, dall’altro. La suddetta conclusione, peraltro, ap…

The article critically analyzes the Italian regulation of subcontracting in the context of public tenders as recently amended by several legislative measures in compliance with the infringement procedure launched by the European Commission against Italy. According to the Author’s view the current legislative framework – characterized by the almost overall elimination of the previous limits (probably even going beyond what the European Commission requested) – lacks in finding a fair balance between the principle of the maximum participation in the tender on the one hand and the need to prevent and reveal potential collusive conduct on the other. Furthermore this conclusion is supported by the analysis of the regulation of the causes of exclusion from the tender still too timid in envisaging the optional exclusion of the participants due to anticompetitive conduct.

La Media Education al Centro Tau. Dalla teoria alla pratica

2022

Il contributo illustra le attività di media education del Centro Tau di Palermo come approccio per la costruzione di una civic intentionality (Mihailidis and Thevenin 2013) nei giovani che frequentano questo centro di aggregazione giovanile collocato in una delle aree più colpite da disagio sociale della città di Palermo.

Non solo Platone. Il primato dell'oralità nel retore Alcidamante

2020

Il saggio è dedicato all’orazione Sugli autori dei discorsi scritti o sui sofisti, attribuita al retore Alcidamante, discepolo di Gorgia e attivo in Atene tra il 410 e il 365 a.C. Argomento dell’orazione è il serrato confronto tra due differenti modalità oratorie, l’autoschediazein (“parlare a braccio”) — cui Alcidamente accorda una netta superiorità — e il "gegrammena legein (“pronunciare discorsi scritti”). L’interesse di questo testo (databile con buona approssimazione intorno al 390 a. C) consiste essenzialmente nel rappresentare un punto di vista specificamente retorico sulla questione delle differenze tra scritto e parlato. Nonostante alcune significative convergenze con il ben più ce…

The essay focuses on the speech “Perì Sophiston” (Concerning Sophists) attributed to Alcidamas a rhetorician who was pupil of Gorgias and thought in Athens between 410 and 365 BC. In this speech Alcidamas stresses the superiority of extempore (though prepared) speeches over written one. The speech is particularly interesting because it represents the specifically rhetorical point of view on the issue of the differences between written and spoken word. The essay underlines the originality of Alcidamas (especially compared to Plato) and his interest also in the contemporary debate on the differences between written and spoken.Settore M-FIL/05 - Filosofia E Teoria Dei Linguaggi

La crisi pandemica ha accelerato la diffusione di ambienti di apprendimento caratterizzati dall'uso intensivo della tecnologia. Questa novità rappresenta un obiettivo trasversale della professionalizzazione del docente universitario, con una particolare declinazione sul versante pedagogico-didattico-valutativo quale questione strategica per lo sviluppo dell’alta formazione. Il contributo illustra i risultati di una ricerca condotta con 119 docenti universitari neoassunti e 20 Direttori di dipartimento. La finalità della ricerca è stata, da una parte, rilevare la percezione dei docenti neoassunti relativa alle proprie competenze didattiche, metacognitive e valutative, con riferimento alla di…

The pandemic crisis has accelerated the diffusion of learning environments characterized by the intensive use of technology. This novelty represents a transversal objective of the professionalization of the university teacher with a particular declination on the pedagogical-didactic-evaluation side as a strategic issue for the development of higher education. This paper presents the results of research conducted with 119 newly recruited university teachers and 20 Department Directors. The aim of the research was on the one hand to detect the perception of newly hired teachers related to their teaching metacognitive and evaluative skills with reference to distance learning to highlight specific characteristics that could have encouraged or hindered adaptation to this new condition. On the other hand through the qualitative research the aim has been to penetrate in depth the challenges posed by the digital revolution at University by carrying out 20 interviews with privileged witnesses who represent on the national scene agents of institutional change. The results showed a certain awareness of the need to integrate new ways of teaching to increase interest participation and enthusiasm for technology.Settore M-PED/03 - Didattica E Pedagogia Speciale

Abitare nel reale. Dalla crisi della periferia alla tessitura di nuove relazioni contestuali

2019

I progetti redatti per “Palermo Sud-Est” sono il risultato di un Laboratorio di Laurea strutturatosi attraverso incontri, seminari, comunicazioni specialistiche, esposizioni critiche, che – in una strategia condivisa – ha visto ogni studente elaborare il proprio lavoro nel confronto con gli altri attori del Laboratorio stesso. La ricerca sui “progetti urbani” è stata impostata di modo che ogni laureando fosse messo a conoscenza dei progetti svolti nello stesso ambito territoriale dai colleghi che l’avevano preceduto, così da poter operare in continuità e contribuire a formulare un ragionamento unitario, nel quale ogni progetto costituisse continuazione, verifica o anche variante dei precede…

The projects prepared for "Palermo South-East" are the result of a Graduate Laboratory structured through meetings seminars specialist communications critical exhibitions which - in a shared strategy - saw each student elaborate their work in comparison with others actors of the same Laboratory. The research on "urban projects" was set so that each graduating student was made aware of the projects carried out in the same geographical area by the colleagues who had preceded it so as to be able to operate in continuity and contribute to formulating a unitary reasoning in which each project constituted continuation verification or even variant of the previous ones. These coordinated works have pursued two fundamental objectives: the strengthening of infrastructures and the establishment of specialized public buildings with superior functions aimed at requalifying and regenerating various critical situations with particular attention to the relationship between context and life scenarios. Thus each designer while dealing with a main functional program simultaneously deals with various issues such as the rationalization of the road system the redevelopment of existing buildings the design and refunctionalization of urban services (for example the transformed Central Station in the hotel or the project of a great Mosque)several degree theses have addressed as the main theme or as a question in the background the design of a new bed for the Oreto river and the relative establishment of a park facing it. In this desire to "patch up the wounds" in the different areas of "Palermo South-East" in close relationship with the vicissitudes of the place there is a continuous reference to architectures of all time and some questions involving the functional program are suggested - that identifies the character (or perhaps "type") of what is to be inserted in a given context - and the qualities of living reality as a pivotal material in the design process.Settore ICAR/14 - Composizione Architettonica E Urbana
