Dante e il prog italiano

L'articolo investiga gli espliciti riferimenti alla Commedia dantesca che hanno attraversato la produzione musicale cosiddetta progressive italiana. L'analisi è centrata soprattutto sui rapporti tra il testo dantesco e i testi dei dischi presi in esame, cercando di individuare le dinamiche di riuso dei versi del poema (si va dalla citazione letterale a semplici suggestioni di tipo strutturale) in un arco temporale che parte dal primo accenno a Dante nel disco Ut dei New Trolls (1972) per arrivare agli ultimissimi anni (l'ultimo disco di cui si parla, Il Pozzo dei Giganti dei Cherry Five è del 2015).The essay investigates the explicit references to Dante's Commedia that can be found in the so-called Italian progressive music production. The analysis is centered above all on the relationships between Dante's poem and the lyrics of the musical works examined, trying to identify the dynamics of reuse of the verses of the poem, from literal quotation to structure's suggestions. The period involved in the study starts from the first mention of Dante in New Trolls' Ut (1972) since the very latest years

«Già Roma, or Babilonia» (appunti su Rerum vulgarium fragmenta CXXXVI-CXXXVIII)

Il trittico dei sonetti anti-avignonesi oggetto di queste mie poche annotazioni è tutt’altro che scarsamente studiato. Si potrebbe dividere la fortuna critica in modo magari un po’ grossolano, in due fasi principali. La prima fase, quella diciamo così dei commenti antichi (tra Cinque e Settecento), è stata attratta primariamente dall’elemento fortemente polemico di questi sonetti, quello stesso elemento che, per inciso, ha portato come si sa alla censura del ciclo (censura applicata alla fonte, tramite esclusione di questi sonetti dal commento, o addirittura in alcuni casi meccanicamente sugli esemplari stessi, con i nostri sonetti cancellati da tratti di penna o asportati insieme alle carte che li contenevano).Come esemplari di questo primo momento potrei qui ricordare le dilatate esegesi del Daniello o, ancor più, del Gesualdo, in cui tra l’altro vengono già chiaramente additati per la prima volta i rapporti strettissimi che il gruppo intrattiene con le Sine nomine avignonesi, principalmente con SN 18 (da collegare soprattutto, anche se non solo, al primo sonetto della serie, Fiamma dal ciel) ma anche con la 8 e la 10 (da cui l’immagine rispettivamente del «turrificus atque simul terrificus Nembroth» Clemente VI che rimbalza nel gioco «le torre superbe [...] / et i suoi torrer’» di L’avara Babilonia 10-11, e appunto di Nembroth, ancora, che «superbis turribus celum petens»), la 5 ecc

Memoria poetica. Questioni filologiche e problemi di metodo

Il convegno ha analizzato la funzione nella poesia medievale e rinascimentale della cosiddetta \u201cmemoria poetica\u201d, ovvero la ripresa, conscia o meno, da parte di un poeta, di stilemi, versificazione, lessemi, rime e altri elementi gi\ue0 precedentemente impiegati in opere proprie o altrui. La memoria poetica \ue8 stata soprattutto analizzata nelle sue intersezioni con i problemi della ricostruzione filologica

Measurement of the cosmic ray spectrum above 4×10184{\times}10^{18} eV using inclined events detected with the Pierre Auger Observatory

A measurement of the cosmic-ray spectrum for energies exceeding $4{\times}10^{18}$ eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\circ}$ detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above $5.3{\times}10^{18}$ eV, the "ankle", the flux can be described by a power law $E^{-\gamma}$ with index $\gamma=2.70 \pm 0.02 \,\text{(stat)} \pm 0.1\,\text{(sys)}$ followed by a smooth suppression region. For the energy ($E_\text{s}$) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find $E_\text{s}=(5.12\pm0.25\,\text{(stat)}^{+1.0}_{-1.2}\,\text{(sys)}){\times}10^{19}$ eV.Comment: Replaced with published version.

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared to the data of the surface detector stations of the Observatory, which provide well-calibrated information on the cosmic-ray energies and arrival directions. The response of the radio stations in the 30 to 80 MHz regime has been thoroughly calibrated to enable the reconstruction of the incoming electric field. For the latter, the energy deposit per area is determined from the radio pulses at each observer position and is interpolated using a two-dimensional function that takes into account signal asymmetries due to interference between the geomagnetic and charge-excess emission components. The spatial integral over the signal distribution gives a direct measurement of the energy transferred from the primary cosmic ray into radio emission in the AERA frequency range. We measure 15.8 MeV of radiation energy for a 1 EeV air shower arriving perpendicularly to the geomagnetic field. This radiation energy -- corrected for geometrical effects -- is used as a cosmic-ray energy estimator. Performing an absolute energy calibration against the surface-detector information, we observe that this radio-energy estimator scales quadratically with the cosmic-ray energy as expected for coherent emission. We find an energy resolution of the radio reconstruction of 22% for the data set and 17% for a high-quality subset containing only events with at least five radio stations with signal.Comment: Replaced with published version.

Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy

We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8 \pm 0.7 (stat) \pm 6.7 (sys) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principle calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the direct calibration of any cosmic-ray radio detector against the well-established energy scale of the Pierre Auger Observatory.Comment: Replaced with published version.

Incidence and Predictors of Infections and All-Cause Death in Patients with Cardiac Implantable Electronic Devices: The Italian Nationwide RI-AIAC Registry

The incidence of infections associated with cardiac implantable electronic devices (CIEDs) and patient outcomes are not fully known. To provide a contemporary assessment of the risk of CIEDs infection and associated clinical outcomes. In Italy, 18 centres enrolled all consecutive patients undergoing a CIED procedure and entered a 12-months follow-up. CIED infections, as well as a composite clinical event of infection or all-cause death were recorded. A total of 2675 patients (64.3% male, age 78 (70-84)) were enrolled. During follow up 28 (1.1%) CIED infections and 132 (5%) deaths, with 152 (5.7%) composite clinical events were observed. At a multivariate analysis, the type of procedure (revision/upgrading/reimplantation) (OR: 4.08, 95% CI: 1.38-12.08) and diabetes (OR: 2.22, 95% CI: 1.02-4.84) were found as main clinical factors associated to CIED infection. Both the PADIT score and the RI-AIAC Infection score were significantly associated with CIED infections, with the RI-AIAC infection score showing the strongest association (OR: 2.38, 95% CI: 1.60-3.55 for each point), with a c-index = 0.64 (0.52-0.75), p = 0.015. Regarding the occurrence of composite clinical events, the Kolek score, the Shariff score and the RI-AIAC Event score all predicted the outcome, with an AUC for the RI-AIAC Event score equal to 0.67 (0.63-0.71) p < 0.001. In this Italian nationwide cohort of patients, while the incidence of CIED infections was substantially low, the rate of the composite clinical outcome of infection or all-cause death was quite high and associated with several clinical factors depicting a more impaired clinical status
