Adaptive detection of signals embedded in correlated Gaussian noise has been an active field of research in the last decades. This topic is important in many areas of signal processing such as, just to give some examples, radar, sonar, communications, and hyperspectral imaging. Most of the existing adaptive algorithms have been designed following the lead of the derivation of Kelly's detector which assumes perfect knowledge of the target steering vector. However, in realistic scenarios, mismatches are likely to occur due to both environmental and instrumental factors. When a mismatched signal is present in the data under test, conventional algorithms may suffer severe performance degradation. The presence of strong interferers in the cell under test makes the detection task even more challenging. An effective way to cope with this scenario relies on the use of "tunable" detectors, i.e., detectors capable of changing their directivity through the tuning of proper parameters. The aim of this book is to present some recent advances in the design of tunable detectors and the focus is on the so-called two-stage detectors, i.e., adaptive algorithms obtained cascading two detectors with opposite behaviors. We derive exact closed-form expressions for the resulting probability of false alarm and the probability of detection for both matched and mismatched signals embedded in homogeneous Gaussian noise. It turns out that such solutions guarantee a wide operational range in terms of tunability while retaining, at the same time, an overall performance in presence of matched signals commensurate with Kelly's detector.

Tells the forgotten story of post-Rossinian opera buffa, with attention to masterpieces by Donizetti and fascinating comic works by Luigi Ricci, the young Verdi, and other composers. This study represents the first substantial assessment of Italian comic operas composed during the central years of the Risorgimento -- the period during which upheavals, revolutions, and wars ultimately led to the liberation andunification of Italy. Music historians often view the period as one during which serious Romantic opera flourished in Italy while opera buffa inexorably declined. Laughter between Two Revolutions revises this widespread notion by viewing well-known comic masterpieces -- such as Donizetti's L'elisir d'amore (1832) and Don Pasquale (1843) -- as part of a still-thriving tradition. Also examined are opere buffe by LuigiRicci, Lauro Rossi, Verdi (Un giorno di regno), and others, many of which circulated widely at the time. Francesco Izzo's pathbreaking study argues that in the "realm of seriousness" of mid-nineteenth-century Italy, comedywas not an anachronistic intruder, but a significant and vital cultural presence. This important volume offers new insights into opera history and theories of comedy in the arts. It will be of interest to opera lovers everywhere and to students in music, philosophy, comparative literature, and Italian cultural studies. Francesco Izzo is senior lecturer in music at the University of Southampton.

The 20th century has finished, the century when surgery took huge steps forward thanks to progress in technology. Now we have entered the "century of biotechnologies", which will not only generate progress in surgery, but also lead to a real "cultural revolution" that will completely change approaches to solving different problems in medicine. The aim of this book is to bring surgeons closer to biotechnologies and to overcome the cultural gap dividing them from these new approaches. Biotechnologies are already proposed and used at different levels in surgical practice: in diagnostic technique, enabling practitioners to identify diseases at an early stage and follow their molecular modification over time; and in tissue engineering, where the use of "smart scaffolds" offers a possible answer to increasing demand for biocompatible tissues and organs in transplantation surgery. This volume focuses on the emerging field of stem cells, analyzing both their role as possible players in originating and perpetuating cancer – "cancer stem cells" – and, conversely, their extraordinary therapeutical potential. An additional section is dedicated to the evaluation and application of derived molecular factors that can enhance the physiological processes that are fundamentally important in surgery, such as hemostasis and wound healing. Surgeons have always been technologists, in the sense that since surgery began they have always needed technology, beginning with a scalpel and surgical instruments. They have always cooperated with technologists. However, in the new century, the first one of the millennium, a rapid increase in knowledge that is outside the realm of the surgeon’s traditional technological training is imposing itself – hence the aim of this book. It is now urgent to encourage surgeons to embrace this knowledge (biotechnology) with confidence. By its very nature, biotechnology is completely different from the technologies used so far, because it escapes the senses of sight and touch, which up to now have been the essence of the surgeon’s work. The cellular and molecular dimensions of biotechnologies are still far removed from most of the recent advances in modern surgical techniques. A common language between surgeons and biotechnologists will create further, revolutionary, progress in surgical sciences in the twenty-first century.
We study the impact of bank credit on firm productivity. We exploit a matched firm-bank database covering all the credit relationships of Italian corporations, together with a natural experiment, to measure idiosyncratic supply-side shocks to credit availability and to estimate a production model augmented with financial frictions. We find that a contraction in credit supply causes a reduction of firm TFP growth and also harms IT-adoption, innovation, exporting, and adoption of superior management practices, while a credit expansion has limited impact. Quantitatively, the credit contraction between 2007 and 2009 accounts for about a quarter of observed the decline in TFP.
Italian Dominance On The Dance Culture Of 80's. The only book in the world that tells the true story of Italian disco music through the artistic events of the most representative characters, with interviews, statements and news unpublished.
Title first published in 2003. Much has been written about the problems minorities encounter in Western European and North American cities. This insightful volume acknowledges the deep-rooted nature of inequalities and discrimination, but seeks ways of ameliorating and eradicating them from positive stories of minority involvement in regeneration.
The racism and antisemitism of Fascist Italy have often been described as ‘mild’, ‘cultural’, ‘spiritual’, and essentially non-violent, especially in comparison with the racial ideology of Nazi Germany. This book challenges this simplistic interpretation with a thorough analysis of the texts and images of the magazine La Difesa della razza (Defence of the race), the principal public voice of Fascist biological racism, which appeared fortnightly between 1938 and 1943 under the editorship of Telesio Interlandi, Mussolini’s ‘unofficial mouthpiece’, with governmental financial support. A negative icon of the propaganda of Fascist racism, La Difesa della razza first appeared in August 1938 shortly before the passing of Italy’s Racial Laws, but had a long gestation. It was the expression of a Fascist cultural milieu – journalists, writers, artists, and architects – headed by Interlandi, whose racism and antisemitism dated back to the end of the First World War. By placing the magazine’s emergence in this longer timescale, and exploring the interrelationships of political action, ideological discourse, and imagery, this book also demonstrates how the project of ‘anthropological revolution’ – building the New Man – was a central element of Italian Fascism, from the very beginning to the deportation of Italian Jews. This new English edition has been thoroughly revised and updated.

La crescita esponenziale dell’interesse per la ventilazione non invasiva (NIV) verificatasi negli ultimi 10-15 anni, non solo dal punto di vista clinico e applicativo, ma anche speculativo, ha pochi eguali nella recente storia della medicina. In Italia e in Europa in generale tale metodica è applicata su larga scala, prevalentemente nei reparti di Pneumologia e nelle Unità di Cure Intermedie Respiratorie, mentre per quanto riguarda la sua applicazione nei reparti di Terapia Intensiva Generale (UTI) i dati emersi da uno studio multicentrico condotto nei paesi francofoni vedono la NIV impiegata in una quantità di casi che rappresenta fino al 50% dei pazienti che richiedono assistenza ventilatoria. Il recente studio EUROVENT ha inoltre dimostrato come la NIV non si limiti alla sua applicazione “acuta”, dal momento che circa 25.000 pazienti sono attualmente ventilati “in cronico” a domicilio. Inoltre, si calcola che milioni di cittadini europei soffrano attualmente di disturbi respiratori durante il sonno, e per molti di essi il trattamento medico di prima scelta è rappresentato dalla NIV. Questo libro si propone lo scopo di richiamare l’attenzione sulle più recenti acquisizioni in questo campo, con la speranza di fornire uno strumento valido e maneggevole per la scelta e l’impostazione della migliore modalità di ventilazione.
This book reflects on the political capacity of citizen users to impact politics, explaining the danger in assuming that mass online participation has unconditionally democratising effects. Focusing on the case of Italy's Five Star Movement, the book argues that Internet participation is naturally unequal and, without normative and strong design efforts, Internet platforms can generate noisy, undemocratic crowds instead of self-reflexive, norm-bounded communities. The depiction of a democratising Internet can be easily exploited by those who manage these platforms to sell crowds as deliberating publics. As the Internet, almost everywhere, turns into the primary medium for political engagement, it also becomes the symbol of what is wrong with politics. Internet users experience unprecedented, instantaneous and personalised access to information and communication and, by comparison, they feel a much stronger level of irrelevance in the existing political system.
These memories, handwritten by Elmo Cermaria (Nonno Peppe) for his grandson Checco (Francesco Nicolini), tell of when, as a young man of 20, he found himself hurled into the inferno of the First World War. In those days, you could cry your heart out for a bread roll denied, then miraculously regained thanks to the compassion of a German soldier, “the hated enemy”. These recollections are terse, without a trace of rhetoric and devoid of recriminations. Nonno Peppe tells the facts just as he experienced them first hand, without expressing any condemnation of those responsible for them, even though an awareness of the large-scale massacre he witnessed transpires from his account. When Nonno Peppe delivered the manuscript to his grandson on his wedding day, he asked him to make a promise: “Let the President of the Republic know what we did for Italy.” A hundred years ago, whole generations of young Italian men were stripped of human honor and dignity. Only a few of these young men would live on and become our grandfathers; and only a few of us would be fortunate enough to become “grandchildren of the Great War” and bear witness to their ordeal.
