Signal processing in photonic crystals and nanostructures
2006
International audience; Optical devices employing photonic crystals and novel nanostructure materials may exhibit useful properties for applications to all-optical signal processing. In this work we analyze as a first example four-wave mixing of polarized beams in photonic crystal fibers. We show that by properly tuning the pump wavelength and the linear dispersion properties of the fiber one may obtain broadband parametric amplification and frequency conversion. Next we consider the in-line periodic amplification of short optical pulses by means of quantum-dot semiconductor optical amplifiers. We show by numerical simulations that pattern-free amplification of a 40 Gbit/s soliton signal at…

Genetic profile and immunohistochemical study of clear cell renal carcinoma: Pathological-anatomical correlation and prognosis.
2021
Abstract Introduction Renal cell carcinoma (RCC) accounts for 2–3% of all tumors being the most frequent solid lesion in the kidney. Objective To determine what genetic alterations and immunohistochemical (IHC) of clear cell renal carcinoma (ccRCC) are associated with prognosis and tumor aggressiveness. Patients and Methods Experimental analytical study with 57 patients who underwent radical and partial nephrectomy between 2005 and 2011, all with diagnosis of ccRCC and minimum post-operative follow-up of 36 months. The pathological study included IHC determination of biomarkers associated (CAIX, CAM 5.2, CD10, c-erbB-2, EGFR, HIF-1a, Ki67, MDM2, PAX-2 y 8, p53, survivin and VEGFR 1 and 2). …
Optical Amplification in Hollow-Core Negative-Curvature Fibers Doped with Perovskite CsPbBr
2019
We report a hollow-core negative-curvature fiber (HC-NCF) optical signal amplifier fabricated by the filling of the air microchannels of the fiber with all-inorganic CsPbBr3 perovskite nanocrystals (PNCs). The optimum fabrication conditions were found to enhance the optical gain, up to +3 dB in the best device. Experimental results were approximately reproduced by a gain assisted mechanism based on the nonlinear optical properties of the PNCs, indicating that signal regeneration can be achieved under low pump powers, much below the threshold of stimulated emission. The results can pave the road for new functionalities of the HC-NCF with PNCs, such as optical amplification, nonlinear frequen…
La pianificazione portuale tra semplificazione del procedimento e valorizzazione della partecipazione
2013
I porti, nel quadro del posizionamento competitivo dei territori, sono oggetto di un ampio dibattito che propone una riforma della fase amministrativa della pianificazione. Il contributo propone una chiave di lettura ricostruttiva del procedimento pianificatorio nell'ottica della valorizzazione della semplificazione, coniugata alla garanzia della partecipazione .
High Bias Voltage CZT Detectors for High-flux Measurements
2017
In this work, we present the performance of new travelling heater method (THM) grown CZT detectors, recently developed at IMEM-CNR Parma, Italy. Thick planar detectors (3 mm thick) with gold electroless contacts on CZT crystals grown by Redlen Technologies (Victoria BC, Canada) were realized, with a planar cathode covering the detector surface (4.1 x 4.1 mm(2)) and a central anode (2 x 2 mm(2)) surrounded by a guard ring electrode. The detectors, characterized by low leakage currents at room temperature (4.7 nA/cm(2) at 1000 V/cm), allow good room temperature operation even at high bias voltages (> 7000 V/cm). At low rates, the detectors exhibit an energy resolution around 4 % FWIEM at 59.5…
Microscale X-ray mapping of CZT arrays: Spatial dependence of amplitude, shape and multiplicity of detector pulses
2018
In this work, we present the results of a microscale X-ray mapping of a 2 mm thick CZT pixel detector, with pixel pitches of 500 μm and 250 μm, using collimated synchrotron X-ray sources at the Diamond Light source (U. K.). The detector is dc coupled to a fast and low noise ASIC (PIXIE ASIC), characterized only by the preamplifier stage. A custom 16-channel digital readout electronics was used, able to perform online fast pulse shape and height analysis (PSHA), with low dead time and reasonable energy resolution at both low and high fluxes. The detector allows high bias voltage operation (> 5000 V/cm) and good energy resolution at room temperature (5.3 %, 2.3 % and 2.1 % FWHM at 22.1, 59…
La riforma amministrativa e la semplificazione del procedimento amministrativo: considerazioni sull'attività degli enti locali alla luce della trasfo…

La «semplificazione» del processo civile (d.lgs. 150/2011, pubblicato nella g.u. del 21 settembre 2011 in vigore dal 6 ottobre 2011)
2011
Con il d.lgs. 150/2011 il legislatore ha inteso unificare in un microcodice la sel- va selvaggia di riti esistenti nella legislazione speciale, riconducendoli entro tre modelli, ispirati ai riti «codicistici» del lavoro, sommario e ordinario di cogni- zione. I vecchi riti defunti, però, sono risuscitati come l’araba fenice sotto le spo- glie di ventotto nuovi sottoriti, ognuno con le sue peculiarità e differenze rispet- to ai modelli base (già diversi dai corrispondenti codicistici). Sotto altro profilo, poi, il decreto costituisce l’ennesimo capitolo di una convulsa attività riformisti- ca, che ha caratterizzato e caratterizza tuttora la storia della legislazione proces- suale. L’opera si …
La semplificazione normativa nel PNRR: il coinvolgimento dei legislatori regionali tra progetti bandiera e poteri sostitutivi
2021
The essay concerns the involvement of Regional Legislators in the implementation of National Recovery and Resilience Plan («Piano nazionale di ripresa e resilienza»), considering regulatory simplification measures programmed by the Plan. In this perspective, it proposes a comparison between the Plan and the Italian Simplification Agenda 2020-2023 and it examines the framework of regional regulatory simplification measures.
