Molecular dynamics simulations of heavy ion induced defects in SiC Schottky diodes
2018
Heavy ion irradiation increases the leakage current in reverse-biased SiC Schottky diodes. This letter demonstrates, via molecular dynamics simulations, that a combination of bias and ion-deposited energy is required to produce the degradation. Peer reviewed

A blow-up result for a nonlinear wave equation on manifolds: the critical case
2021
We consider a inhomogeneous semilinear wave equation on a noncompact complete Riemannian manifold (Formula presented.) of dimension (Formula presented.), without boundary. The reaction exhibits the combined effects of a critical term and of a forcing term. Using a rescaled test function argument together with appropriate estimates, we show that the equation admits no global solution. Moreover, in the special case when (Formula presented.), our result improves the existing literature. Namely, our main result is valid without assuming that the initial values are compactly supported.

Semiotica marcata: frammenti di un manifesto
2021
Da un primo calcolo approssimativo, incrociando gli scritti raccolti nella biblioteca personale con gli elenchi presenti nel suo sito, le bibliografi e qui e là, le informazioni sparse del web, le indicazioni di amici e colleghi nonché le memorie personali, il numero degli scritti di Paolo Fabbri – fra libri, saggi, articoli, introduzioni, postfazioni, curatele, interviste e traduzioni – su pera i 500 titoli. E, portando avanti l’esplorazione, tale numero è sicuramente destinato ad aumentare. Per un presunto abbas agraphicus non c’è male: immagine romanzata di un intellettua le che tocca forse rivedere, non tanto per ragioni di quantità ma per la profondità di pensiero e la forza retorica d…
Quotidianità e virus: un diario semiotico
2021
Beyond health issues, we know that the pandemic has changed our daily lives. Accelerating socio-cultural trends that were already present in our contemporaneity, such as functionalism, the control of bodies, the fear of others, forced hygiene, the reduction of essential freedoms, work from home ... The semiologist, constantly on the hunt of signals and symbols to be interpreted, he thus tried to intercept some of these modulations of daily life, with a kind of diary in public, sprinkled with various insights proposed to readers of various kinds. The following text is a partial collection of these notes, which, read now, may perhaps change their meaning, and interest those who, out of desper…
Dy159 Electron-Capture: A New Candidate for Neutrino Mass Determination
2021
International audience; The ground state to ground state electron-capture Q value of Dy159 (3/2-) has been measured directly using the double Penning trap mass spectrometer JYFLTRAP. A value of 364.73(19) keV was obtained from a measurement of the cyclotron frequency ratio of the decay parent Dy159 and the decay daughter Tb159 ions using the novel phase-imaging ion-cyclotron resonance technique. The Q values for allowed Gamow-Teller transition to 5/2- and the third-forbidden unique transition to 11/2+ state with excitation energies of 363.5449(14) keV and 362.050(40) keV in Tb159 were determined to be 1.18(19) keV and 2.68(19) keV, respectively. The high-precision Q value of transition 3/2-…
Blade runners and daredevils : a case study on the representation of two Paralympians in The Guardian
2015
Paralympialaiset ja vammaisurheilu jäävät mediassa usein “vammattomien” urheilun uutisoinnin varjoon. Aiempien tutkimusten mukaan median luomat representaatiot usein myös vahvistavat stereotypioita vammaisista. Erilaisilla kielenkäyttötavoilla, ts. diskursseilla, joilla näitä urheilijoita kuvataan, onkin olennaisesti vaikutusta esimerkiksi siihen, millaiseksi fyysisesti vammaiset kokevat tulevansa kohdelluksi yhteiskunnassa. Tämän takia onkin tärkeää kiinnittää huomiota median luomiin kuviin. Tutkielmassa käsitellään vammaisurheilijoiden representaatiota brittiläislehti The Guardianissa. Analysoin kahta lehden internet-versiossa julkaistua artikkelia, joista toinen käsittelee pikajuoksija O…
