Il restauro del monumento Gravina Bonanno di Montevago nel camposanto di S. Orsola a Palermo
2013
Oggetto della pubblicazione è la tomba mausoleo nel cimitero di S. Orsola di Palermo per Pellegra Gravina Bonanno di Montevago, ultima discendente ed unica erede dei principi di Montevago, tra i cui congiunti erano illustri personalità come il generale Federico Carlo Gravina (lo sconfitto della battaglia di Trafalgar) e il Cardinale Pietro, arcivescovo di Palermo. Il monumento, che si configura come un tempio distico in antis dorico siculo e risente anche di influenze canoviane, viene qui attribuito alla progettazione dell’architetto Emmanuele Palazzotto (1798-1872), autore di importanti architetture a Palermo, tra cui i campanili neogotici sul Palazzo Arcivescovile, e all’esecuzione di Giu…
Tra Tardogotico e Rinascimento: Palermo e la Sicilia occidentale
2008
A partire dalla seconda metà del XV secolo, l'approdo a Palermo di scultori di formazione toscana comporta un riequilibrio dei rapporti di forza nel cantiere di architettura. Agli scultori (marmorari) si chiede sempre più spesso l'esecuzione di altari, porte, finestre, colonne che sfrut¬tano un linguaggio all'antica. La formazione di corporazioni professionali (nel 1487) può essere letta come una efficace replica del mondo gotico alle pressioni del classicismo; contemporaneamente l'attività e il successo in Sicilia occidentale di importanti maestri (Carnilivari, Casada, Belguardo) confermano la vitalità dell'ultimo gotico e la sua capacità di confrontarsi e intrecciarsi con la storia e le t…
Las torres del portal de Cuarte de Valencia y su función carcelaria
2007
Las torres de tos portales de Cuarte y de Serranos en la muralla cristiana de la ciudad de Valencia pudieron salvarse en la segunda mitad del Ochocientos a causa de albergar prisiones, mientras el resto del muro urbano estaba siendo inmolado. El presente artículo se ocupa de las primeras: sus comienzos constructivos y su historia penitenciaria desde el siglo XVII, así como su posterior destino guareciendo prisiones militares entre la década de 1820 y 1946. Además las torres de Cuarte fueron mudos testigos de ciertas reformas urbanas y otros acontecimientos. (A)
Properties of the Binary Neutron Star Merger GW170817
2019
On August 17, 2017, the Advanced LIGO and Advanced Virgo gravitational-wave detectors observed a low-mass compact binary inspiral. The initial sky localization of the source of the gravitational-wave signal, GW170817, allowed electromagnetic observatories to identify NGC 4993 as the host galaxy. In this work, we improve initial estimates of the binary's properties, including component masses, spins, and tidal parameters, using the known source location, improved modeling, and recalibrated Virgo data. We extend the range of gravitational-wave frequencies considered down to 23 Hz, compared to 30 Hz in the initial analysis. We also compare results inferred using several signal models, which ar…
All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO O2 data
2019
We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast-spinning neutron stars with an asymmetry around their rotation axis, using data from the second observing run of the Advanced LIGO detectors. We employ three different semi-coherent methods ($\textit{FrequencyHough}$, $\textit{SkyHough}$, and $\textit{Time-Domain $\mathcal{F}$-statistic}$) to search in a gravitational-wave frequency band from 20 to 1922 Hz and a first frequency derivative from $-1\times10^{-8}$ to $2\times10^{-9}$ Hz/s. None of these searches has found clear evidence for a CW signal, so we present upper limits on the gravitational-wave strain amplitude $h_0$ (the …
All-sky search for short gravitational-wave bursts in the second Advanced LIGO and Advanced Virgo run
2019
We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo. We search for gravitational-wave transients with a duration of milliseconds to approximately one second in the 32-4096 Hz frequency band with minimal assumptions about the signal properties, thus targeting a wide variety of sources. We also perform a matched-filter search for gravitational-wave transients from cosmic string cusps for which the waveform is well-modeled. The unmodeled search detected gravitational waves from several binary black hole mergers which have been identified by previous analyses. No other significant event…
Search for Tensor, Vector, and Scalar Polarizations in the Stochastic Gravitational-Wave Background
2018
The detection of gravitational waves with Advanced LIGO and Advanced Virgo has enabled novel tests of general relativity, including direct study of the polarization of gravitational waves. While general relativity allows for only two tensor gravitational-wave polarizations, general metric theories can additionally predict two vector and two scalar polarizations. The polarization of gravitational waves is encoded in the spectral shape of the stochastic gravitational-wave background, formed by the superposition of cosmological and individually-unresolved astrophysical sources. Using data recorded by Advanced LIGO during its first observing run, we search for a stochastic background of generic…
Excimer laser atherectomy in an uncrossable long chronic total occlusion through the subintimal space
2020
We present a successfully chronic total occlusions (CTO) coronary recanalisation with the subadventitial space by excimer laser atherectomy (ELCA) adjunctive therapy. Angiogram revealed non-significant diffuse disease of the left coronary system with a complex long proximal right coronary artery (RCA) CTO (J-CTO score 4) and collaterals (Rentrop Grade 2 and Werner classification CC1) from the septal branches (Figure 1, Panel A). CTO PCI of the RCA was then indicated and planned. Initially, antegrade approach and a retrograde approach technique were attempted without success. Thereafter, a rescue Antegrade Dissection Reentry strategy (ADR) was applied. A Pilot 200 (Abbott) was advanced in a …
Unconventional phases of attractive Fermi gases in synthetic Hall ribbons
2017
An innovative way to produce quantum Hall ribbons in a cold atomic system is to use M hyperfine states of atoms in a one-dimensional optical lattice to mimic an additional "synthetic dimension." A notable aspect here is that the SU(M) symmetric interaction between atoms manifests as "infinite ranged" along the synthetic dimension. We study the many-body physics of fermions with SU(M) symmetric attractive interactions in this system using a combination of analytical field theoretic and numerical density-matrix renormalization-group methods. We uncover the rich ground-state phase diagram of the system, including unconventional phases such as squished baryon fluids, shedding light on many-body…
Effects of cimetidine, atropine and prostaglandin E2 on rat mucosal erosions produced by intragastric distension
1980
Abstract The effects of three typical antisecretory agents: cimetidine, atrophine and prostaglandin E2 were compared on an acute rat gastric ulcer model which consisted of perfusing the stomach continuously, at a high intraluminal pressure (120 mm H2O), with a simulated gastric juice (0.1 M HCl plus 600 mg pepsin/1). As the acid and pepsin are given exogenously the inhibitory action of the antisecretory drugs is obviated in this model. Cimetidine and atropine failed to reduce gastric erosions, whereas prostaglandin E2 markedly reduced the severity of the mucosal lesions with respect to control values. Long-term treatment with cimetidine also failed to increase the resistance of the gastric …
