A special case of murder committed by pitchfork
2011
The autors describe a murder case, happened in a rural environment, done with an agricultural instrument with "four peak". The use of agricultural instruments to commit a murder, frequent in the past, nowadays is unusual if not in a rural environment.
Fiscal Policy and Asset Price Cycles: Evidence from Four European Countries
2014
OS; International audience; We test for non-linear effects of asset prices on the fiscal policy of four major European economies (France, Italy, Spain and UK). We model government spending and revenue as time-varying transition probability Markovian processes (TVPMS), and find that: (i) in France and Italy, the impact of housing prices on government revenue is conditioned by the phase of the stock price cycle; (ii) a similar asymmetric pattern is found for the UK when considering the effect of stock price fluctuations on government revenue and spending vis-à-vis the troughs and peaks of aggregate wealth; and (iii) for Spain, a fall in government revenue is typically associated with a negati…
LA QUALITÀ DEL MANGO PRODOTTO IN SICILIA, ASPETTI COLTURALI DELLA PAPAYA, DEL LICI E DEL NESPOLO DEL GIAPPONE
2016
L’introduzione di specie arboree da frutto di origine tropicale e subtropicale in Sicilia non è nuova ma solo negli ultimi anni si assiste ad una crescita esponenziale delle superfici investite. Infatti, se alberi come il Nespolo del Giappone fanno ormai parte della nostra cultura frutticola da decenni, mango, lici e papaia fino a qualche anno fa erano poco conosciuti sulle nostre tavole. Nel giro di poco tempo questi frutti hanno conquistato un posto stabile tra le preferenze del consumatore con spazi di mercato in continuo aumento. La coltivazione di questi fruttiferi di origine tropicale presuppone precise risposte sulla fattibilità di nuovi impianti e sulle modalità di conduzione agrono…
Periodic time-domain modulation for the electrically tunable control of optical pulse train envelope and repetition rate multiplication
2012
An electrically tunable system for the control of optical pulse sequences is proposed and demonstrated. It is based on the use of an electrooptic modulator for periodic phase modulation followed by a dispersive device to obtain the temporal Talbot effect. The proposed configuration allows for repetition rate multiplication with different multiplication factors and with the simultaneous control of the pulse train envelope by simply changing the electrical signal driving the modulator. Simulated and experimental results for an input optical pulse train of 10 GHz are shown for different multiplication factors and envelope shapes. © 2006 IEEE.
Signal processing and frequency-dependent associative memory based on nanoswitches
2008
A signal processing concept based on nanoscale switches whose conductance can be tuned by an external stimulus between two (ON and OFF) states is proposed and analyzed theoretically. The building block of the system is formed by a metal nanoparticle linked to two electrodes by an organic ligand and a molecular switch. When we apply an alternating potential to the system of the same frequency as the periodic variation between the ON and OFF states induced on the switch, the net charge delivered by the system exhibits a sharp resonance. This resonance can be used to process an external signal by selectively extracting the weight of the different harmonics. In addition, a frequency-dependent a…
New Molecular-Based Materials for Enabling Electro-Optical Bistability in the Silicon Photonics Platform
2019
Electro-optical bistability is a functionality which can be crucial for a wide range of applications as it can enable non-volatile and ultra-low power switching performance. We investigate the integration of a molecular-based material presenting a Spin Crossover (SCO) effect in the silicon platform for enabling optical bistability. The SCO phenomenon involves a switching process between two molecular spin states. This spin transition comes along with a change in the optical refractive index that can be switched by different external stimuli such as a variation of temperature or light irradiation and which has a hysteretic behaviour. The SCO material can be synthetized as nanoparticles so th…
Active Plasmonics in True Data Traffic Applications: Thermo-Optic On/Off Gating Using a Silicon-Plasmonic Asymmetric MachZehnder Interferometer
2012
We present the first system-level demonstration of an active plasmonic device in 10-Gb/s data traffic conditions. An asymmetric silicon-plasmonic Mach-Zehnder interferometer with dielectric-loaded plasmonic waveguides serving as the electrically controlled arms, operates as thermo-optic ON/OFF gating element with 2.8-mu s response time and 10.8-mW power consumption.

Optical switching of quantum states inside self-assembled quantum dots
2008
Abstract Photoluminescence and excitation of photoluminescence spectroscopy have been performed for two kinds of single InAs self-assembled quantum dots grown on GaAs. The presence of unintentional impurities (donors and acceptors) offers the possibility to switch from negative to positively charged excitons by selectively exciting impurity related optical transitions.
'Apparently, women don't know how to operate doors': a corpus-based analysis of women stereotypes in the tv series 3rd Rock from the Sun
2017
This paper explores how women stereotypes are discursively evaluated in the TV sitcom 3 rd Rock from the Sun by paying attention to the societal, cultural and ideological values they convey. Following recent trends for the study of television series (Bednarek, 2010), the analysis is both qualitative and quantitative, adopting a Corpus- Assisted Discourse Analysis approach (Baker, 2006; Partington, 2004). The contextualised analysis of words that refer to women confirms that the sitcom writers of 3 rd Rock from the Sun purposefully resort to stereotyping as a verbal strategy to create humour while conveying negative attitudes towards women.
Digital Hydraulic Technology for Linear Actuation:A State of the Art Review
2020
This paper analyses the current state of the art in linear actuation with digital hydraulics. Based on the differences in their aims the paper partitions the area into four actuation concepts – parallel valve solutions, single switching valve solutions, multi-chamber cylinders, and multi-pressure cylinders. The concepts are evaluated based on accuracy and smoothness of motion, switching load, reliability, efficiency and the number of components required.
