The 2021 G20 and Italy: keeping our dreams alive?
2022
Italy’s presidency of the G20 defied the odds and resulted in costly commitments by the members on a range of issues: global health, climate change, a minimum global tax, and the crisis in Afghanistan. How can we explain this success? Italy’s prime minister, Mario Draghi, and his extensive prior experience and widespread respect was certainly a factor. The global context was also important, with the new Biden administration in the US leading a group of countries seeking multilateral solutions to pressing international problems.
The Infinite-Valued Łukasiewicz Logic and Probability
2017
The paper concerns the algebraic structure of the set of cumulative distribution functions as well as the relationship between the resulting algebra and the infinite-valued Łukasiewicz algebra. The paper also discusses interrelations holding between the logical systems determined by the above algebras.

L'analyse de la monnaie et de la finance par David Hume : conventions, promesses, régulations
2008
De l’apport de David Hume a l’analyse economique, un aspect est generalement retenu : son approche presumee quantitative de la monnaie. Or, lorsqu’on resitue l’examen des relations monetaires et financieres a l’interieur de son corpus philosophique, il revele d’autres perspectives. Selon Hume, le processus de civilisation institue certaines fictions, qui permettent aux individus de forger un ordre symbolique. Dans une economie de marche, la distinction entre la monnaie – de nature conventionnelle – et les engagements financiers – assimiles a des promesses – est centrale. Alors que les conventions monetaires autorisent de multiples agencements, les engagements financiers doivent etre etroite…
La conformación del cooperativismo en Brasil: tendencias y desafíos en el Siglo XXI
2002
The paper deals with the subject of cooperativism focusing on a view of the co-operative system in Brazil, as well as the process of formation and consolidation of the models and the influences of the different aspects of co-operative thought. We then present an analysis of the process of economic modernisation and the transformations in the co-operative system in the 70s to 90s decades, and lastly, we analyse the current tendencies and challenges for cooperativism in Brazil.
Phospholipid-polyaspartamide micelles for pulmonary delivery of corticosteroids
2011
A novel drug delivery system for beclomethasone dipropionate (BDP) has been constructed through self-assembly of a pegylated phospholipid-polyaminoacid conjugate. This copolymer was obtained by chemical reaction of α,β-poly(N-2-hydroxyethyl)-DL-aspartamide (PHEA) with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethyleneglycol)2000] (DSPE-PEG(2000)-NH(2)). Benefiting from the amphiphilic structure with the hydrophilic shell based on both PHEA and PEG and many hydrophobic stearoyl tails, PHEA-PEG(2000)-DSPE copolymer was able to self assemble into micelles in aqueous media above a concentration of 1.23 × 10(-7)M, determined by fluorescence studies. During the self-assembling …

Representation of solutions and large-time behavior for fully nonlocal diffusion equations
2017
Abstract We study the Cauchy problem for a nonlocal heat equation, which is of fractional order both in space and time. We prove four main theorems: (i) a representation formula for classical solutions, (ii) a quantitative decay rate at which the solution tends to the fundamental solution, (iii) optimal L 2 -decay of mild solutions in all dimensions, (iv) L 2 -decay of weak solutions via energy methods. The first result relies on a delicate analysis of the definition of classical solutions. After proving the representation formula we carefully analyze the integral representation to obtain the quantitative decay rates of (ii). Next we use Fourier analysis techniques to obtain the optimal dec…
Real structures on nilpotent orbit closures
2021
We determine the equivariant real structures on nilpotent orbits and the normalizations of their closures for the adjoint action of a complex semisimple algebraic group on its Lie algebra.
Rigidité, comptage et équidistribution de chaînes de Cartan quaternioniques
2020
We prove an analog of Cartan's theorem, saying that the chain-preserving transformations of the boundary of the quaternionic hyperbolic spaces are projective transformations. We give a counting and equidistribution result for the orbits of arithmetic chains in the quaternionic Heisenberg group.; Nous montrons un analogue d'un théorème de Cartan, disant que les transformations préservant les chaînes sur le bord d'un espace hyperbolique quaternionien est une transformation projective. Nous donnons un résultat de comptage et d'équidistribution pour une orbite de chaînes arithmétiques dans le groupe de Heisenberg quaternionique.
G2019S Variation in LRRK2: An Ideal Model for the Study of Parkinson's Disease?
2019
Parkinson’s disease (PD) is the second most common neurodegenerative disorder and has plagued humans for more than 200 years. The etiology and detailed pathogenesis of PD is unclear, but is currently believed to be the result of the interaction between genetic and environmental factors. Studies have found that PD patients with the LRRK2:G2019S variation have the typical clinical manifestations of PD, which may be familial or sporadic, and have age-dependent pathogenic characteristics. Therefore, the LRRK2:G2019S variation may be an ideal model to study the interaction of multiple factors such as genetic, environmental and natural aging factors in PD in the future. This article reviewed the …
