Les compléments neurophysiologiques du diagnostic
2009
Les recherches presentees mettent en evidence des relations entre anomalies comportementales et cognitives et dysfonctionnements cerebraux sous-jacents a partir de methodes d'exploration electrophysiologique non invasives (electroencephalogramme, potentiels evoques auditifs). Trois types de troubles sont etudies : les troubles du sommeil, l'intolerance au changement et l'exploration visuelle atypique des visages humains. La complementarite des approches cliniques et neurophysiologiques est cruciale aux etapes du diagnostic fonctionnel, de l'intervention therapeutique et educative.
Principal Poincar\'e Pontryagin Function associated to some families of Morse real polynomials
2014
It is known that the Principal Poincar\'e Pontryagin Function is generically an Abelian integral. We give a sufficient condition on monodromy to ensure that it is an Abelian integral also in non generic cases. In non generic cases it is an iterated integral. Uribe [17, 18] gives in a special case a precise description of the Principal Poincar\'e Pontryagin Function, an iterated integral of length at most 2, involving logarithmic functions with only one ramification at a point at infinity. We extend this result to some non isodromic families of real Morse polynomials.
ON THE CALCULATION OF THE HEAT CAPACITY IN PATH INTEGRAL MONTE CARLO SIMULATIONS
1992
In Path Integral Monte Carlo simulations the systems partition function is mapped to an equivalent classical one at the expense of a temperature-dependent Hamiltonian with an additional imaginary time dimension. As a consequence the standard relation linking the heat capacity Cv to the energy fluctuations, <E2>−<E>2, which is useful in standard classical problems with temperature-independent Hamiltonian, becomes invalid. Instead, it gets replaced by the general relation [Formula: see text] for the intensive heat capacity estimator; β being the inverse temperature and the subscript P indicates the P-fold discretization in the imaginary time direction. This heatcapacity estimator…
Absolute measurement of quadratic nonlinearities from phase-matched second-harmonic generation in a single KTP crystal cut as a sphere
1997
We determine within an accuracy of ∼10% the absolute magnitude of the quadratic effective coefficients of types I and II phase-matched second-harmonic generation from conversion efficiency measurements in a single nonlinear crystal cut as a sphere. The agreement is good with measurements performed in thin parallelepipedal samples. The material studied is KTiOPO4, for which improved Sellmeier equations are given.
Digestion and absorption rates of [3H]-oleic acid and [14C]-triolein do not differ in rats fed heated (-) and (+) gossypol cottonseed and soybean flo…
1998
This study was conducted to compare in vivo the acute effects of heated (+) and (-) gossypol cottonseed flours with those of soybean flour on lipid digestion and absorption in growing rats. Rats were fed by gastric intubation mixed [ 3 H]-oleic acid and [ 14 C]-triolein with heated flours or without flour (control). Lipid digestion and absorption were determined for 6 h after meal intubation. Both radioactivities recovered in gastrointestinal tract were significantly higher in rats fed (+) gossypol cottonseed flour than in all other groups. The majority of both recovered radioactivities was found in stomach contents, then in stomach wall and finally in intestinal wall. The distribution of b…
Light-induced transmission nonlinearities in gallium selenide
1999
The intensity of a He–Ne laser (633 nm, 5 mW) transmitted by different GaSe samples is observed to change in correlation with a Nd-yttrium–aluminum–garnet laser pulse (532 nm, 7.8 ns, 3 mJ) which excites them. Such time response has been attributed to a nonlinear optical effect, i.e., a decrease in the refractive index due to the exciton screening by the photogenerated carriers. A calculation of the absorption coefficient and refractive index at different carrier concentrations has led to a reconstruction of transmittance transients which fully agree with the experimental data at different incident intensities and temperatures.

Prognosi sulla sussistenza di una causa di non punibilità e giudizio di proporzionalità della misura cautelare
2020
Analisi critica della decisione di legittimità (Cass., sez. V, 3 marzo 2020, n. 11957) che ha ancorato ad un alto standard di garanzia il parametro di «probabilità della sussistenza della condizione di non punibilità» e, contestualmente, di accedere alla lettura più rigoristica dell'accertamento cautelare, sancendo un ulteriore avvicinamento fra i criteri di valutazione probatoria della fase cautelare e quelli relativi al giudizio di merito. Soluzione, questa, che se da un canto può rappresentare una garanzia di maggiore realizzazione della presunzione di innocenza, limitando al massimo i possibili rischi di una restrizione per l'imputato che poi non subirà la pena dall'altro canto, rischia…
