Il kimono di Odette. Riflessi del japonisme nella musica europea del primo Novecento

2019

Il testo delinea il quadro degli influssi del japonisme nell'ambito della musica francese e italiana dei primi anni del XX secolo, con particolare riferimento a Claude Debussy ("La mer"), Pietro Mascagni ("Iris") e Giacomo Puccini (Madama Butterfly"). Particolare attenzione è infine riservata alle "Trois Poésies de la Lyrique Japonaise" per voce e piccolo ensemble di Igor Stravinsky (1912).

van der Waals interactions between excited atoms in generic environments

2015

We consider the the van der Waals force involving excited atoms in general environments, constituted by magnetodielectric bodies. We develop a dynamical approach studying the dynamics of the atoms and the field, mutually coupled. When only one atom is excited, our dynamical theory suggests that for large distances the van der Waals force acting on the ground-state atom is monotonic, while the force acting in the excited atom is spatially oscillating. We show how this latter force can be related to the known oscillating Casimir--Polder force on an excited atom near a (ground-state) body. Our force also reveals a population-induced dynamics: for times much larger that the atomic lifetime the …

The reaction of the copper(I) β-diketiminate copper complex {(Cu(BDIMes))2(μ-C6H6)} (BDIMes = N,N'-bis(2,4,6-trimethylphenyl)pentane-2,4-diiminate) with the low-valent group 13 metal β-diketiminates M(BDIDip) (M = Al or Ga; BDIDip = N,N'-bis(2,6-diisopropylphenyl)pentane-2,4-diiminate) in toluene afforded the complexes {(BDIMes)CuAl(BDIDip)} and {(BDIMes)CuGa(BDIDip)}. These feature unsupported copper-aluminum or copper-gallium bonds with short metal-metal distances, Cu-Al = 2.3010(6) A and Cu-Ga = 2.2916(5) A. Density functional theory (DFT) calculations showed that approximately half of the calculated association enthalpies can be attributed to London dispersion forces.

Market Impact and Trading Profile of Hidden Orders in Stock Markets

2009

We empirically study the market impact of trading orders. We are specifically interested in large trading orders that are executed incrementally, which we call hidden orders. These are statistically reconstructed based on information about market member codes using data from the Spanish Stock Market and the London Stock Exchange. We find that market impact is strongly concave, approximately increasing as the square root of order size. Furthermore, as a given order is executed, the impact grows in time according to a power law; after the order is finished, it reverts to a level of about 0.5-0.7 of its value at its peak. We observe that hidden orders are executed at a rate that more or less m…

Predictors of Falls and Fractures Leading to Hospitalization in People With Dementia: A Representative Cohort Study.

2018

OBJECTIVES: Investigate predictors of falls and fractures leading to hospitalization in a large cohort of people with dementia. DESIGN: A retrospective cohort study. SETTING AND PARTICIPANTS: People with diagnosed dementia between January 2007 and March 2013, aged >65 years, were assembled using data from the Maudsley Biomedical Research Centre Case Register, from 4 boroughs in London serving a population of 1.3 million people. MEASURES: Falls and/or fractures leading to hospitalization were ascertained from linked national records. Demographic data, cognitive test scores, medications, and symptom and functioning scores from Health of the Nation Outcome Scales (HoNOS65+) were modeled in mul…

Dispersion Interaction between Two Hydrogen Atoms in a Static Electric Field

2019

We consider the dispersion interaction between two ground-state hydrogen atoms, interacting with the quantum electromagnetic field in the vacuum state, in the presence of an external static electric field, both in the nonretarded and in the retarded Casimir-Polder regime. We show that the presence of the external field strongly modifies the dispersion interaction between the atoms, changing its space dependence. Moreover, we find that, for specific geometrical configurations of the two atoms with respect to the external field and/or the relative orientation of the fields acting on the two atoms, it is possible to change the character of the dispersion force, turning it from attractive to re…

Bernardine Evaristo’s The Emperor’s Babe: Re-narrating Roman Britannia, De-essentialising European History

2019

Bernardine Evaristo’s The Emperor’s Babe (2001) contributes to the imaginative disentanglement of the traditional British ethnicity-and-nation nexus and questions the related founding myth of racial purity by featuring the character of Zuleika, a young black woman who is born of Sudanese parents in Roman London. Through the depiction of Zuleika, Evaristo offers a subversive reshaping of some versions of the official British national history in the context of a wider revision of the European classical past. However, in spite of its temporal setting, Evaristo’s historical novel simultaneously engages with contemporary issues of gendered racialisation and national belonging. In its highly orch…

Serum ferritin is a discriminant marker for both fibrosis and inflammation in histologically proven non-alcoholic fatty liver disease patients

2011

INTRODUCTION: Differentiation between steatosis and non-alcoholic steatohepatitis (NASH) in non-alcoholic fatty liver disease (NAFLD) is important as NASH progress to cirrhosis. No specific laboratory/imaging technique exists either to diagnose NASH or to select patients for liver biopsy. PATIENTS AND METHODS: We evaluated serum ferritin and the features of metabolic syndrome with respect to histological inflammation and/or fibrosis in NAFLD patients. The Kleiner scoring system was used to classify NAFLD in consecutive liver biopsies. One hundred and eleven patients: median age 52.6, 64 males, obesity 62, diabetes mellitus (DM) 58, arterial hypertension 26 and hyperlipidaemia 40%. RESULTS: …

Digital image analysis of liver collagen predicts clinical outcome of recurrent hepatitis C virus 1 year after liver transplantation.

2011

Clinical outcomes of recurrent hepatitis C virus after liver transplantation are difficult to predict. We evaluated collagen proportionate area (CPA), a quantitative histological index, at 1 year with respect to the first episode of clinical decompensation. Patients with biopsies at 1 year after liver transplantation were evaluated by Ishak stage/grade, and biopsy samples stained with Sirius red for digital image analysis were evaluated for CPA. Cox regression was used to evaluate variables associated with first appearance of clinical decompensation. Receiver operating characteristic (ROC) curves were also used. A total of 135 patients with median follow-up of 76 months were evaluated. At 1…
