Digital holographic microscopy as a screening technology for diabetes

2019

Label-free quantitative phase imaging (QPI) is the hallmark of digital holographic microscopy (DHM). One of the most interesting medical applications of QPI-DHM is that it can be used to analyze illnesses in which the refractive index or/and the morphology of cells/tissues are distorted, from the acquisition of a single image. In this contribution, we obtain the phase maps of red blood cells (RBCs) samples of patients suffering from diabetes mellitus type 1 (DM1) by using a DHM. Our experimental results show that the measured phase values are significantly different between control non-diabetic and diabetic patients. The high correlation coefficient between the phase and the glycated hemogl…

Interference-assisted detection of dark photon using atomic transitions

2019

Dark photon is a massive vector particle which couples to the physical photon through the kinetic mixing term. Such particles, if exist, are produced in photon beams and, in particular, in laser radiation. Due to the oscillations between the physical photon and the dark photon, the latter may be, in principle, detected in the light-shining-through-a-wall experiment. We propose a variant of this experiment where the detection of dark photons is based on the atomic transitions. The key feature of this scheme is that the detection probability is first order in the coupling constant due to the interference term in the photon and dark photon absorption amplitudes. We expect that such experiment …

A line-shape analysis for spin-1 NMR signals

1997

An analytic model of the deuteron absorption function has been developed and is compared to experimental NMR signals of deuterated butanol obtained at the SMC experiment in order to determine the deuteron polarization. The absorption function model includes dipolar broadening and a frequency-dependent treatment of the intensity factors. The high-precision TE signal data available are used to adjust the model for Q-meter distortions and dispersion effects. Once the Q-meter adjustment is made, the enhanced polarizations determined by the asymmetry and TE-calibration methods compare well within the accuracy of each method. In analyzing the NMR signals, the quadrupolar coupling constants could …

Uno strumento di insegnamento e apprendimento riflessivo nella formazione degli insegnanti al tempo del Covid: lo storytelling digitale

2021

Tra le varie forme narrative, negli ultimi anni si sta diffondendo l’uso del cosiddetto “storytelling digitale”, ovvero uno strumento attraverso il quale lo studente può raccontarsi e ritrovare tutti gli elementi caratterizzanti un’esperienza didattica vissuta. Il contributo si propone l'obiettivo di valutare in termini di soddisfazione e percezione del proprio apprendimento, la ricaduta dell’esperienza narrativa da parte degli studenti universitari che hanno frequentato a distanza nel primo semestre dell’anno accademico 2020-21, il corso di Docimologia previsto al secondo anno (cattedra M-Z) del Corso di Studi in Scienze della Formazione Primaria, attraverso l’impiego dello storytelling di…

Arte digitalizado y arte digital: las manifestaciones artísticas en la era digital

2003

Analizamos las potencialidades que el medio digital ofrece al campo de la creación, constatando la aparición de nuevas obras más interactivas, abiertas y dinámicas y de un nuevo tipo de espectador más activo. Destacamos las repercusiones que este medio está ejerciendo en el mundo de los museos y las galerías que están apostando, en algunos casos, por incorporar estas obras a sus espacios expositivos y al mercado del arte. Reseñamos la importancia de Internet y el surgimiento del net-art, así como de la Realidad Virtual y el Arte evolutivo. (A)

EXCERCISING CRITICAL THINKING THROUGH READING: AN EDUCATIONAL USE OF DIGITAL TEXTS

2016

Questo lavoro si propone di accertare la validità di un percorso formativo incentrato sull’uso della lettura del testo digitale in rapporto allo sviluppo del pensiero critico. Un obiettivo fondamentale da tenere presente nella scuola, a vari livelli, riguarda l’esercizio della capacità critica. La diffusione delle tecnologie tra i nostri giovani provoca una cospicua quantità di stimoli conoscitivi che necessitano di decodifica, attribuzione di senso ed elaborazione costruttiva delle informazioni; i ragazzi devono potenziare abilità che non riguardano soltanto l'uso degli strumenti digitali, ma devono imparare a selezionare ed interpretare i dati, a gestire e valutare le informazioni trovate…

Il ruolo della comparazione giuridica nella contesa per la sovranità digitale

2023

The article scrutinises the main narratives adopted by the E.U., the U.S. and China in the fight for digital sovereignty. It analyses the ongoing dialogue between legal systems that is taking place in the digital sphere to ponder on the role of comparative law in this dialogue. With legal systems called to apply a territorial law to a global phenomenon, comparative law proves to be a fundamental tool in the dispute for digital sovereignty, widely employed across legal formants, with a critical role in creating a distinctive identity for the legal systems.

3D #DigitalInvasions: a crowdsourcing project for mobile user generated content

2015

This paper introduces the #InvasioniDigitali project which is an online crowdsourcing initiative started in Italy in 2013 with the aim to promote the value of and engagement with local heritage. The paper focuses on two case studies of pilot ‘invasions’ using 3D data capture by students at museums and heritage sites in Sicily.

Virtual Currency: New Step in Monetary Development

2016

Abstract Money is perhaps the best recognized and at the same time less understood figure of economy. During the evolution of a monetary science starting from the eighteenth century and fundamental works on such questions as true nature and main functions of money, the approach and theories about monetary science have changed significantly up to date not reaching the final state. The twenty-first century can be characterized with a vast development of technologies and the increase use of the internet which significantly succeeded the development of monetary system introducing a new phenomenon - virtual currencies. While remaining rather illusive, virtual currencies have been broadly noted b…
