Quantumness and speedup limit of a qubit under transition frequency modulation
2022
Controlling and maintaining quantum properties of an open quantum system along its evolution is essential for both fundamental and technological aims. We assess the capability of a frequency-modulated qubit embedded in a leaky cavity to exhibit enhancement of its dynamical quantum features. The qubit transition frequency is sinusoidally modulated by an external driving field. We show that a properly optimized quantum witness effectively identifies quantum coherence protection due to frequency modulation while a standard quantum witness fails. We also find an evolution speedup of the qubit through proper manipulation of the modulation parameters of the driving field. Importantly, by introduc…
Chińska aktywność na Bałkanach w XXI wieku i jej implikacje
2022
Celem artykułu jest szkicowe przedstawienie, na podstawie analiz i materiałów prasowych, wielosektorowej obecności Chin na Bałkanach i jej wpływu na sytuację ekonomiczną regionu. Bałkany są ważne dla mocarstw ze względu na położenie geopolityczne i geostrategiczne na skrzyżowaniu szlaków międzykontynentalnych. Chiny znacząco wpływają na ekonomikę poszczególnych państw region, wykorzystując dyplomację publiczną celem ograniczenia wpływów ze strony innych ważnych graczy: Unii Europejskiej, Rosji i USA. Autorka przedstawia hipotezę, że Chiny, tak jak USA pod koniec XX wieku, zmierzają do stworzenia sfery wpływów na Półwyspie Bałkańskim, w kontekście swoich interesów globalnych. Bałkany są post…
Fundamental limits for transmission modulation in VO2 metasurfaces
2022
The interest in dynamic modulation of light by ultra-thin materials exhibiting insulator–metal phase transition, such as VO 2 , has rapidly grown due to the myriad industrial applications, including smart windows and optical limiters. However, for applications in the telecommunication spectral band, the light modulation through a thin VO 2 film is low due to the presence of strong material loss. Here, we demonstrate tailored nanostructuring of VO 2 to dramatically enhance its transmission modulation, reaching a value as high as 0.73, which is 2 times larger than the previous modulation achieved. The resulting designs, including free-topology optimization, demonstrate the fundamental limit i…
Divenire minoranza, il trattamento della follia in età borbonica. L’Ospizio di Santa Teresa di Palermo (XIX secolo)
2022
Interessanti spunti riguardanti il trattamento della follia si ricavano dal contesto siciliano all’inizio del XIX secolo, periodo in cui si perfeziona il controllo sociale da parte delle istituzioni. Nello specifico, si vuole qui proporre il caso dell’Ospizio di Santa Teresa di Palermo, l’ex noviziato dei Teresiani Scalzi poco fuori le mura della città di Palermo, istituto adibito nel 1802, durante il soggiorno forzato della corte borbonica in Sicilia e il protettorato inglese, al contenimento dei cosiddetti «incurabili», cioè di qualsiasi minaccia che potesse interferire o interagire con la società sana del tempo. Interesting insights into the treatment of madness are to be gained from the…

Una ragionevole apologia di John Stuart Mill
2022
La libertà di espressione è tra i valori più cari al costituzionalismo liberale moderno e contemporaneo. Limitare la libertà di ciascuno di dire ciò che vuole è, da questa prospettiva, sempre guardato con sospetto.Giorgio Maniaci nel suo saggio si scaglia apertamente contro questa prospettiva.L’idea di Maniaci è che la menzogna sia pericolosissima e vada dunque estirpata dai discorsi pubblici. Questo perché la libertà di espressione non è un valore in sé ma è uno strumento a sostegno della democrazia e della possibilità dei cittadini di formarsi un’opinione libera e scientificamente corretta. Le credenze falsificate dalla scienza non hanno diritto di cittadinanza nel discorso pubblico. In q…
ESTUDIO SOBRE LOS REFERENTES FEMENINOS EN LA EDUCACIÓN MUSICAL.
2022
A lo largo de la historia de la música de occidente, las mujeres han tenido pocas oportunidades a la hora de acceder profesionalmente al ámbito musical, pero sí es cierto que una minoría consiguió acceder al mismo. Sin embargo, los manuales y los programas académicos tradicionalmente solo recogen los referentes masculinos más destacados. El objetivo principal de este artículo es identificar cuál es la percepción del sector, concretamente entre las profesionales que se dedican a la composición, dirección orquestal o a la docencia de estudios musicales. Para ello, se utilizó la técnica de la entrevista estructurada. Se analizó una muestra de respuestas de compositoras, docentes y directoras d…
Dataset related to the article "LITHOTRIPSY OF CALCIFIED AORTIC VALVE LEAFLETS BY A NOVEL ULTRASOUND TRANSCATHETER-BASED DEVICE"
2022
This record contains raw data related to the article “LITHOTRIPSY OF CALCIFIED AORTIC VALVE LEAFLETS BY A NOVEL ULTRASOUND TRANSCATHETER-BASED DEVICE” The increasing incidence of calcific aortic valve disease necessitates the elaboration of new strategies to retard the progression of the pathology with an innovative solution. While the increasing diffusion of the transcatheter aortic valve replacements (TAVRs) allows a mini-invasive approach to aortic valve substitution as an alternative to conventional surgical replacement (SAVR) in an always larger patient population, TAVR implantation still has contraindications for young patients. In addition, it is liable to undergo calcification with …
Glenoid bone loss in anterior shoulder dislocation: a multicentric study to assess the most reliable imaging method
2022
Purpose: The aim of this multicentric study was to assess which imaging method has the best inter-reader agreement for glenoid bone loss quantification in anterior shoulder instability. A further aim was to calculate the inter-method agreement comparing bilateral CT with unilateral CT and MR arthrography (MRA) with CT measurements. Finally, calculations were carried out to find the least time-consuming method. Method: A retrospective evaluation was performed by 9 readers (or pairs of readers) on a consecutive series of 110 patients with MRA and bilateral shoulder CT. Each reader was asked to calculate the glenoid bone loss of all patients using the following methods: best fit circle area on…
Not all bull and bear markets are alike: insights from a five-state hidden semi-Markov model
2022
This paper employs the hidden semi-Markov model and a novel model selection procedure to detect different states in the US stock market. The empirical results suggest that the market is switching between five states that can be classified into three bull states and two bear states. The three bull states are categorized as a low volatility bull market, a high volatility bull market, and a stock market bubble. One of the bear states represents a regular bear market, while the other one corresponds to either a stock market crash or a market correction. The paper demonstrates that the five-state model is consistent with a number of stylized facts and provides many valuable insights into the dyn…
In dialogo su libertà di espressione, riso e violenza
2022
Il saggio si inserisce in un volume in cui dialogano filosofi del diritto e filosofi del linguaggio. Nello specifico lo scritto di Clelia Bartoli discute con quello di Salvatore Di Piazza il cui cuore tematico riguarda le dinamiche che si generano all’interno di un triangolo i cui vertici sono costituiti da tre concetti: il riso, la libertà di espressione e la violenza. L’argomentazione del filosofo del linguaggio usa come banco di prova un caso emblematico: «La satira à la Charlie Hebdo, ovvero la presa in giro irriverente, caustica e politicamente scorretta». Di Piazza debutta con un paio di domande: «si può ridere di tutto?» e «si può dire di tutto in un discorso connesso al riso?». In a…
Ragioni mostruose.
2022
In questo capitolo rielaboro la distinzione, proposta da Danblon e Donckier, tra regimi di razionalità fondati sul logos o sul mythos, proponendo una interpretazione cognitiva della ‘interazione mostruosa’ di questi due regimi che, secondo le autrici, costituirebbe uno carattere di alcune forme di comunicazione contemporanea.

Host’s genetic background determines the outcome of reciprocal faecal transplantation on life-history traits and microbiome composition
2022
Abstract Background Microbes play a role in their host's fundamental ecological, chemical, and physiological processes. Host life-history traits from defence to growth are therefore determined not only by the abiotic environment and genotype but also by microbiota composition. However, the relative importance and interactive effects of these factors may vary between organisms. Such connections remain particularly elusive in Lepidoptera, which have been argued to lack a permanent microbiome and have microbiota primarily determined by their diet and environment. We tested the microbiome specificity and its influence on life-history traits of two colour genotypes of the wood tiger moth (Arctia…

Noterelle al «Filostrato» e al «Ninfale fiesolano» di Giovanni Boccaccio
2022
Abstract: This paper presents three brief reading notes on as many passages of the Filostrato (IV 51:1-8; IV 56, 4-8) and the Ninfale fiesolano (229, 1-5) by Giovanni Boccaccio, in the search for probable classical and medieval latin sources and models that have so far escaped the attention of scholars.
Didactique et méthodologie du rythme du français pour apprenants adultes : un état des lieux et des perspectives
2022
L’enseignement-apprentissage du rythme de la langue enseignée et étudiée, la langue française dans ce cas, n’a pas, de nos jours, une place prépondérante en didactique et méthodologie de la langue française, malgré l’impossibilité de le dissocier de l’intonation, des sons et du système de communication. En interrogeant personnellement des étudiants en français en Espagne sur leur perception du rythme en tant qu’objet d’étude et en consultant globalement une partie de l’offre méthodologique éditoriale actuelle pour apprenants adultes (méthodes de français général et ouvrages complémentaires spécialisés en phonétique), on arrive en effet à des constats de vides et de déséquilibres dans l’ense…
Clinical and Epidemiologic Features of Viral Gastroenteritis in Hospitalized Children: An 11-Year Surveillance in Palermo (Sicily)
2022
In order to acquire information regarding viral agents and epidemiologic features of severe paediatric Viral Acute Gastroenteritis (VAGE) across multiple seasons in the pre-rotavirus-vaccine era, the epidemiologic characteristics of VAGE were investigated among paediatric patients hospitalized in a major Sicilian paediatric hospital from 2003 to 2013. Overall, 4725 children were observed and 2355 (49.8%) were diagnosed with a viral infection: 1448 (30.6%) were found positive to rotavirus, 645 (13.7%) to norovirus, 216 (4.6%) to adenovirus, and 46 (0.97%) to astrovirus. Viral infections showed different patterns of hospitalization in terms of age at risk (younger for rotavirus and adenovirus…

Under the magnifying glass: critical moments in virtual exchange
2022
Virtual Exchange (VE) is a form of experiential learning that relies heavily on learning-by-doing and reflection. The present study draws on visual data comprising students’ perceptions of critical learning incidents presented under an imaginary magnifying glass. To complete this project-closing reflective activity, the students had to describe a critical moment that they had experienced during VE and present it in a visual form. Data was collected longitudinally, in three projects (2019, 2020, and 2021) that followed the same pedagogical design and focused on the theme of tourism. The collaborating universities were from three countries: Poland, Finland, and the Netherlands. We used the me…

Removing ocular artifacts from magnetoencephalographic data on naturalistic reading of continuous texts
2022
Naturalistic reading paradigms and stimuli consisting of long continuous texts are essential for characterizing the cortical basis of reading. Due to the highly dynamic nature of the reading process, electrophysiological brain imaging methods with high spatial and temporal resolution, such as magnetoencephalography (MEG), are ideal for tracking them. However, as electrophysiological recordings are sensitive to electromagnetic artifacts, data recorded during naturalistic reading is confounded by ocular artifacts. In this study, we evaluate two different pipelines for removing ocular artifacts from MEG data collected during continuous, naturalistic reading, with the focus on saccades and blin…
Glucagon-Like Peptide-1 Receptor Agonists and Dual Glucose-Dependent Insulinotropic Polypeptide/Glucagon-Like Peptide-1 Receptor Agonists in the Trea…
2022
The obesity pandemic is accompanied by increased risk of developing metabolic syndrome (MetS) and related conditions: non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH), type 2 diabetes mellitus (T2DM) and cardiovascular (CV) disease (CVD). Lifestyle, as well as an imbalance of energy intake/expenditure, genetic predisposition, and epigenetics could lead to a dysmetabolic milieu, which is the cornerstone for the development of cardiometabolic complications. Glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) and dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RAs promote positive effects on most components of the “ cardiometabolic continuum” an…

Cronbach’s alpha in mathematics education research: Its appropriateness, overuse, and alternatives in estimating scale reliability
2022
Critiques of coefficient alpha as an estimate of scale reliability are widespread in the literature. However, the continuous overuse of this statistic in mathematics education research suggests a disconnection between theory and practice. As such, this article argues, in a non-technical way, for the limited usefulness of coefficient alpha, its overuse, and its alternatives in estimating scale reliability. Coefficient alpha gives information only about the degree of the interrelatedness of a set of items that measures a construct. Contrary to the widely circulated misconceptions in mathematics education research, a high coefficient alpha value does not mean the instrument is reliable, and it…
Il “corpo proprio” e il sentire in comune: Empfindung, Einfühlung, Mitgefühl. La dinamica del sentire e la questione dell’empatia fra Sulzer ed Herder
2022
The contribution aims to identify some theoretical lines that cross the German Enlightenment reflection from Leibniz and Wolff to Herder, focusing on the relationship between oneself and otherness, between the dimension of “one’s own body” and the theme of “feeling in common”. Thus, we propose to identify some of the flow lines along which reflection on empathy develops. Keywords: Empathy, German Enlightenment, Herder, Self and Otherness, Sulzer
The Chemistry and the Anti-Inflammatory Activity of Polymethoxyflavonoids from Citrus Genus
2022
Polymethoxyflavonoids (PMFs) are a large group of compounds belonging to the more general class of flavonoids that possess a flavan carbon framework decorated with a variable number of methoxy groups. Hydroxylated polymethoxyflavonoids (HPMFs), instead, are characterized by the presence of both hydroxyl and methoxy groups in their structural unities. Some of these compounds are the aglycone part in a glycoside structure in which the glycosidic linkage can involve the −OH at various positions. These compounds are particular to Citrus genus plants, especially in fruits, and they are present mainly in the peel. A considerable number of PMFs and HPMFs have shown promising biological activities …

The aim of the present study is to assess any difference in the effectiveness of the IL-1β antagonist canakinumab prescribed as first-line biologic agent between the systemic and the chronic-articular Still’s disease.MethodsData were drawn from the retrospective phase of the AutoInflammatory Disease Alliance (AIDA) international registry dedicated to Still’s disease. Patients with Still’s disease classified according to internationally accepted criteria (Yamaguchi criteria and/or Fa…
EU heritage diplomacy : entangled external and internal cultural relations
2022
Cultural heritage is an expanding yet contested area of EU policymaking, which has recently been identified as an instrument for EU international cultural relations. In this article, drawing from critical heritage studies and recent scholarship on heritage diplomacy, we see external and internal cultural relations as blurred and deeply entangled in EU heritage policies. Empirically, we focus on the European Heritage Label (EHL), a central EU heritage policy instrument. We explore how heritage practitioners at selected EHL sites and EU heritage policymakers understand and give meanings to international cultural relations and explain the role of cultural heritage in diplomatic endeavours. Our…

Aineenopettajaksi opiskelevien koulukokemuksia sukupuolistuneesta väkivallasta
2022
Artikkelissa tarkastelemme sukupuolistunutta väkivaltaa aineenopettajaopiskelijoiden koulukokemusten näkökulmasta. Merkittävä määrä nuorista altistuu väkivallan ja häirinnän eri muodoille. Kouluterveyskyselyjen mukaan erityisesti tyttöihin ja sukupuolivähemmistöihin kohdistuva väkivalta ja seksuaalinen häirintä ovat viime vuosien aikana lisääntyneet huolestuttavasti. Koulun ja opettajien rooli ilmiöön puuttumisessa on tärkeä, samoin opettajankoulutuksen, jonka aikana opiskelijoiden olisi tärkeä tulla tietoiseksi väkivallan ilmenemismuodoista ja niihin puuttumisen mahdollisuuksista. Tutkimuksen aineisto kerättiin fokusryhmähaastatteluilla, joihin osallistui yhteensä 18 aineenopettajaopiskeli…
