Intramuscular migration of calcium deposits into the deltoid muscle: two cases of a rare complication of rotator cuff calcific tendinopathy

2023

Rotator cuff calcific tendinopathy is a common non-traumatic shoulder pain condition that occurs predominantly in the supraspinatus tendon. Ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT) is a valid treatment in the resorptive phase. A complication of calcific tendinopathy is migration of calcium deposits outside the tendon. The most common site of migration is the subacromialsubdeltoid bursa (SASD). Another, but not frequent, type of migration is the intramuscular migration which mostly affects the supraspinatus, the infraspinatus and the biceps brachii muscles. This paper reports two cases of migration of calcification from the supraspinatus tendon to the delt…

Uncommon evolutions and complications of common benign liver lesions

2018

International audience; Frequently encountered on abdominal imaging studies, the majority of common benign liver lesions are asymptomatic, confidently diagnosed by imaging, and do not require further workup, follow-up, or treatment. The increasing use of multimodality liver imaging, has allowed the recognition of uncommon evolutions of common benign liver lesions such as size changes, fibrotic regression, and content and vascularization changes, and their complications such as rupture, hemorrhage, thrombosis, extrinsic compression, and malignancy. The purpose of this pictorial review is to describe and illustrate the incidence and diagnostic features of these uncommon evolutions and complic…

Definition of analytical cleaning procedures for archaeological pottery from underwater environments: The case study of samples from Baia (Naples, So…

2021

Abstract This work is focused on a multidisciplinary study of 13 pottery fragments collected in the submerged archaeological site of Baia (Naples, Italy). Founded by the Romans in the 1st century B.C., this archaeological area represents one of the greatest evidences of Roman architecture and it includes ancient ruins whose structures range from maritime villas and imperial buildings. Several diagnostic tests were carried out in order to characterize the archaeological materials, their structure and properties, as well as the alteration and degradation products. Degradation forms in seawater imply not only a variation in the physico-mechanical and chemical properties of the material but als…

Complex-Valued Independent Component Analysis of Natural Images

2011

Linear independent component analysis (ICA) learns simple cell receptive fields fromnatural images. Here,we showthat linear complex-valued ICA learns complex cell properties from Fourier-transformed natural images, i.e. two Gabor-like filters with quadrature-phase relationship. Conventional methods for complex-valued ICA assume that the phases of the output signals have uniform distribution. We show here that for natural images the phase distributions are, however, often far from uniform. We thus relax the uniformity assumption and model also the phase of the sources in complex-valued ICA. Compared to the original complex ICA model, the new model provides a better fit to the data, and leads…

Triumphus musicae. Contributions musicales et spectacles éphémères en l’honneur de Charles III à Palerme (1735)

2017

L'articolo esamina le notizie musicali connesse ai festeggiamenti per l'incoronazione a Palermo nel 1735 di Carlo III di Borbone. In particolare si seguono le fasi fondamentali delle celebrazioni, partendo dagli eventi musicali promossi dal viceré duca di Montemar e da altri nobili palermitani prima dell'arrivo del sovrano, per poi spostarsi all'evento vero e proprio. L'attenzione si concentra quindi sulla serenata ai Quattro Canti per l'entrata trionfale, sugli spettacoli musicali organizzati nel 'Teatrino' della Marina e infine sulle sontuose musiche eseguite durante l'incoronazione in cattedrale.

Music, Religious Communities, and the Urban Dimension: Sound Experiences in Palermo in the Sixteenth and Seventeenth Centuries

2018

Negli ultimi anni la ricerca musicologica ha rinnovato il proprio interesse nei confronti delle istituzioni musicali palermitane, sottolineando l'importanza della ricerca d'archivio per condurre a una ricostruzione del modo concreto in cui la musica risuonava in un contesto specifico. Questo approccio parte da una visione che considera l'elemento musicale quale componente essenziale dell'esperienza urbana, secondo i modelli della cosiddetta 'Urban Musicology' che riconosce la funzione svolta da tutti i luoghi di un dato spazio, non soltanto dalle grandi chiese con le loro cappelle musicali, ma anche dalle istituzioni meno in vista. In questa prospettiva occorre considerare il concetto di “s…

A Semiotic Approach to the Design of Non-speech Sounds

2006

In the field of auditory display there is currently a lack of theoretical support for the design of non-speech sounds as elements of a user interface. Sound design methods are often based on ad hoc choices or the personal preferences of the designer. A method is proposed in this paper based on a semiotic approach to the design of non-speech sounds. In this approach, the design process is conceptualised by referring to structural semiotics, acknowledging the unique qualities of non-speech sounds, as a mode of conveying information. This method is based on a rich use scenario presented to a design panel. A case study where the design method has been applied is presented and evaluated. Finally…
