"Operettizzare" Donizetti: il caso della "Figlia del reggimento"
On the basis of wide-ranging statistical surveys, recent pioneering studies on operetta in Italy of the second half of the 19th century have shown that the repertoire of the tour companies involved in the diffusion process of the genre built their repertoires drawing on two main sources: from one side, operettas imported from France performed in the original language or, more frequently, translated; on the other hand, new operettas composed in Italian by Italian composers (De Lucca, 2019; Oliva, 2020). Less known is the fact that sometimes they also appeared on the billboards of operetta companies titles of the Italian comic opera repertoire of the more or less recent past. This re-contextu…
Rozmieszczenie Ophioglossum vulgatum (Ophioglossaceae) w Polsce oraz jego nowe stanowiska
2020
The paper describes the distribution of Ophioglossum vulgatum in Poland, including localities recorded after 2000, and gives three new O. vulgatum sites in south-eastern Poland. Two of them are located in the Low Beskids in Bednarka and Żydowskie, and the third in the Zamojska Valley in Klemensów.
The Peregrine soliton in nonlinear fibre optics
2010
International audience; The Peregrine soliton is a localized nonlinear structure predicted to exist over 25 years ago, but not so far experimentally observed in any physical system. It is of fundamental significance because it is localized in both time and space, and because it defines the limit of a wide class of solutions to the nonlinear Schrödinger equation (NLSE). Here, we use an analytic description of NLSE breather propagation to implement experiments in optical fibre generating femtosecond pulses with strong temporal and spatial localization, and near-ideal temporal Peregrine soliton characteristics. In showing that Peregrine soliton characteristics appear with initial conditions th…
Acousto-optic interaction in biconical tapered fibers: shaping of the stopbands
2016
The effect of a gradual reduction of the fiber diameter on the acousto-optic (AO) interaction is reported. The experimental and theoretical study of the intermodal coupling induced by a flexural acoustic wave in a biconical tapered fiber shows that it is possible to shape the transmission spectrum, for example, substantially broadening the bandwidth of the resonant couplings. The geometry of the taper transitions can be regarded as an extra degree of freedom to design the AO devices. Optical bandwidths above 45 nm are reported in a tapered fiber with a gradual reduction of the fiber down to 70 μm diameter. The effect of including long taper transition is also reported in a double-tapered st…
Nonlinear spectral shaping and optical rogue events in fiber-based systems
2012
International audience; We provide an overview of our recent work on the shaping and stability of optical continua in the long pulse regime. Fibers with normal group-velocity dispersion at all-wavelengths are shown to allow for highly coherent continua that can be nonlinearly shaped using appropriate initial conditions. In contrast, supercontinua generated in the anomalous dispersion regime are shown to exhibit large fluctuations in the temporal and spectral domains that can be controlled using a carefully chosen seed. A particular example of this is the first experimental observation of the Peregrine soliton which constitutes a prototype of optical rogue-waves.
Peregrine soliton generation and breakup in standard telecommunications fiber
2011
International audience; We present experimental and numerical results showing the generation and breakup of the Peregrine soliton in standard telecommunications fiber. The impact of non-ideal initial conditions is studied through direct cut back measurements of the longitudinal evolution of the emerging soliton dynamics, and is shown to be associated with the splitting of the Peregrine soliton into two subpulses, with each subpulse itself exhibiting Peregrine soliton characteristics. Experimental results are in good agreement with simulations.
Le rôle des paratextes dans l’interprétation de la contrainte de La disparition de Georges Perec
2013
Tutkimuksen kohteena on Georges Perecin kokeellinen romaani La disparition (Denoël 1969). Tarkemmin pureudutaan romaanin parateksteihin, eli varsinaista kertomusta ympäröiviin teksteihin, jotka tekevät tekstistä kirjan. Niitä ovat tässä tutkimuksessa otsikko, kirjailijan nimi, alkusanat, esipuhe, sisällysluettelo, väliotsikot, jälkisanat, takakansiteksti sekä teoksen loppuun sijoitettu osio ”Métagraphes”, johon Perec on valikoinut sitaatteja. Tutkimuksen tavoitteena on selvittää, miten kyseiset paratekstit ohjaavat teoksen tulkintaa: mikä on kunkin paratekstin tehtävä. Tulkinta määritellään tässä tutkimuksessa sekä yksilölliseksi että kollektiiviseksi merkityksenannoksi, johon limittyy myös…
