Summary of Section “New Accelerators, Detectors, Calculus and New Technologies”
No full textDeployment and development of advanced technologies for accelerators, detectors, electronics and computing is inherent in everyday activity of all research projects and experiments funded by INFN. However, when a part of the
research work can be clearly identified as an R&D activity aimed at the development of a new technology or procedure for specific, or a more general, application it is
worthwhile to cut it off and manage it as an independent self-consistent experiment. For many of them it is also easy to find applications in other research discipline or industry. In this case it is important to verify the potentiality of the technology, customize it and improve it, in collaboration with the end user, for the specific
application

Fair and Equitable Treatment and the Fabric of General Principles
No full textThis book moves from the circumstance whereby currently the obligation to provide fair and equitable treatment (FET) to foreign investments is included in the majority of international investment agreements and has proved to be the most invoked standard in investor-State arbitration. Hence, it is no overstatement to describe this standard as the basic norm of international investment law. Yet both its meaning and normative basis continue to be shrouded in ambiguity and, as a consequence, to inspire a considerable number of interpretations by legal writers. The book's precise aim is to unravel such ambiguity, arguing from the idea that FET has become part of the fabric of general international law, but has done so by means of a source somewhat neglected in legal doctrine. This being the category of general principles peculiar to a certain field of international law, i.e. those principles having their own foundations in the international legal order itself, but which, through the mediation of the judge, end up being shaped according to the features typical of a specific normative field. The book, as well as having a solid theoretical backdrop as its basis, offers a careful and critical analysis of pertinent case law, and will prove useful to both scholars and practitioners. Fulvio Maria Palombino is Professor of International Law at the Law Department of the University of Naples Federico II and a member of the Executive Board of the European Society of International Law. Specific to this book: • Explains the ICSID practice clearly and concisely • Useful in practical terms Excerpts from a review: 'Fair and Equitable Treatment and the Fabric of General Principles' is an original and well researched book, in which the author challenges a number of conventional wisdoms on FET.Among the strengths of the book one can mention the solid discussion of public international law principles relevant to FET and the interesting incursions into domestic law legal systems which play an important role in the understanding of FET components such as due process, legitimate expectations or proportionality. In particular the section on promises provides a convincing analysis of the issues that arise when the administration makes an assurance or representation to an investor. Against the backdrop of the examination of unilateral acts under public international law, Palombino's analysis sheds new light on what ought to be the proper scope of protection under the legitimate expectations doctrine in case of governmental promises, clarifying a number of points which have received insufficient attention by arbitral tribunals thus far. - Michele Potestà, Attorney with Lévy Kaufmann-Kohler, Geneva; Senior Researcher, Geneva Center for International Dispute Settlement (CIDS) book review in International and Comparative Law Quarterly, (2018)67(4), 1036-1037.

The Four Engravings : between word and image
No full textThis essay is part of a volume which offers the first comprehensive study of the De Nola (Venice 1514), a hitherto underappreciated Latin text written by the Nolan humanist and physician Ambrogio Leone. Divided into three books and enriched by four engravings, De Nola is an extraordinary historical, chorographical and topographical treatise celebrating the city of Nola in the Kingdom of Naples. Its author was the Nolan physician and humanist Ambrogio Leone, who dedicated the work to Enrico Orsini count of Nola, while its publisher was Joannes Rubeus, or Giovanni Rosso from Vercelli. The volume would mark an important advance in European humanistic and antiquarian debates. Leone’s description of a seemingly minor urban centre in the peninsula is an innovative and ground-breaking work of Renaissance scholarship. Several decades after Biondo Flavio’s studies of Rome and Italy had appeared in print, De Nola marked a shift in antiquarian publications, and opened the way to a new approach to the description of cities. Its fame was enduring, reaching beyond the borders of the Italian peninsula to the main centres of Renaissance European culture. Despite its profound originality and its early and widespread circulation, De Nola has remained at the margins of Renaissance studies.
The chapter written by Fulvio Lenzo discusses the four engravings, which help to make Leone’s book an early sixteenth century masterpiece of humanist literature. His analysis of the engravings clarifies the important role played by Leone himself in planning and drawing the illustrations, and reduces the role of the Venetian painter and engraver Girolamo Mocetto to little more than an executor of Leone’s ideas.
Leone relied, at a first level, on a massive use of written sources relating to a wide range of disciplines. He appears as a reader (and certainly also an owner) of manuscripts and above all of printed editions, like those published by his friend Aldo and composed in Greek characters with the support of Grifo’s renewed Greek typeset; but also as a tireless ‘devourer’ of mathematical and geometrical treatises, like Luca Pacioli’s edition of Euclid. He certainly consulted (or even possibly possessed) illustrated books like the famous Hypnerotomachia Poliphili, or the 1511 edition of Ptolemy’s geographical work (edited by another émigré from the Kingdom of Naples, namely Bernardo Silvano of Eboli), or architectural treatises like Fra Giocondo’s edition of Vitruvius, all printing products which displayed an impressive iconic apparatus; but he also studied a deliberately aniconic book as Leon Battista Alberti’s De re aedificatoria, a real bestseller at the time, where mental images were created by the power of words. Ambrogio Leone considered his book not only a medium for the publication of his text, but also a valuable art object, in which renewed illustrations play a relevant role

A Simple Approximate Long-Memory Model of Realized Volatility
No full textThe paper proposes an additive cascade model of volatility components defined over different time periods. This volatility cascade leads to a simple AR-type model in the realized volatility with the feature of considering different volatility components realized over different time horizons and thus termed Heterogeneous Autoregressive model of Realized Volatility (HAR-RV). In spite of the simplicity of its structure and the absence of true long-memory properties, simulation results show that the HAR-RV model successfully achieves the purpose of reproducing the main empirical features of financial returns (long memory, fat tails, and self-similarity) in a very tractable and parsimonious way. Moreover, empirical results show remarkably good forecasting performance. Copyright The Author 2009. Published by Oxford University Press. All rights reserved.

The thermodynamic limit on Bethe lattices
No full textThe author emphasises the fact that, to obtain the exact solution of Hamiltonian models on Bethe lattices one can apply explicitly the formal method of rigorous statistical mechanics, i.e. the thermodynamic limit of probability measures. This approach solves the well known dichotomy between clashing alternative solutions, and provides a very simple analytic solution for a large class of Hamiltonian models
Semi senza terra. Il padre come funzione di sintesi nell'"Albero dei sogni" di Fulvio Tomizza
No full textL’articolo analizza l’inquietudine di Stefano Marcovich, protagonista del romanzo "L’albero dei sogni" di Fulvio Tomizza nonché alter ego dell’autore stesso, e ne interpreta il destino sotto una sola alterna vicenda: quella della prossimità o della dissociazione rispetto al padre. Delinea quindi la ricerca di un’identità personale, l’esperienza storica e di sé, il conflitto memoria-oblio e la dimensione del sogno all’insegna dell’altruismo e della catarsi per approdare a una placida rigenerazione finale.The article analyzes the restlessness of Stefano Marcovich, protagonist of the novel “The Tree of Dreams” by Fulvio Tomizza as well as alter ego of the author himself, and interprets his destiny under a single alternating story: that of proximity to or dissociation from his father. It therefore outlines the search for a personal identity, the historical and self-experience, the memory-oblivion conflict and the dimension of the dream in the name of altruism and catharsis to arrive at a placid final regeneration
THGEM: A fast growing MPGD technology
No full textThick-GEMs (THGEMs) are simple and robust gaseous multipliers, derived from the GEM design and proposed for large-scale applications. Classical THGEMs consist of Printed Circuit Boards (PCBs) with a regular pattern of
holes obtained by drilling; they are manufactured by industry in large series and large size; their response for different geometrical parameters and operational conditions has been extensively studied. Different substrates (ceramic, glass, PTFE, etc.) and various production procedures have also been investigated with promising results. Different design options, like highly segmented electrodes, and different architectures, in particular those based on the Thick-WELL design are being actively studied. THGEMs are used as gaseous multipliers and as reflective photocathodes for VUV photons when coated with a CsI layer. THGEM-based Photon Detectors have been successfully implemented in 2016 on COMPASS RICH-1 for a total active area of 1.4 m2. Applications of THGEM (also called LEM) technology in the field of cryogenic detectors, in particular for double-phase large volume Ar ones are proposed. The recently discovered phenomenon of bubble assisted electro-luminescence in liquid Xe opens the way to local dual phase cryogenic detector configurations when using THGEMs. The detection of X-rays and neutrons using THGEM-based devices is a very active field. Promising results have been obtained using THGEMs
