Predicting leptonic CP violation in the light of Daya Bay result on theta13
No full textIn the light of the recent Daya Bay result , we reconsider the model presented in Meloni et al. (J. Phys. G 38:015003, 2011), showing that, when all neutrino oscillation parameters are taken at their best fit values of Schwetz et al. (New J. Phys. 10:113011, 2008) and where , the predicted values of the CP phase are δ≈±π/4
La materia del quotidiano. Per un'antropologia degli oggetti ordinari
No full textNegli ultimi vent’anni gli studi antropologici sulla cultura materiale hanno ampliato il raggio dei loro interessi: non più soltanto gli oggetti artigianali delle culture tradizionali, ma anche gli oggetti ordinari della moderna vita quotidiana e del consumo di massa. Merci, doni, arredi domestici, souvenir, oggetti d’affezione stanno al centro dei saggi raccolti in questa antologia, che offre uno spaccato del recente dibattito internazionale. Testi di Mary Douglas, Annette Weiner, Daniel Miller, Orvar Löfgren, Laurier Turgeon, Philippe Bonnin e Martyne Perrot, Sophie Chevalier, Veronique Dassié, Pietro Meloni. Introduzione di Fabio Dei
Le questioni aperte della giustizia penale internazionale nella prospettiva interna
No full textIl volume raccoglie gli atti del convegno di studi Le questioni aperte della giustizia penale internazionale nella prospettiva interna, a cui hanno partecipato docenti universitari, magistrati ed esperti della materia, italiani e internazionali. I contributi trattano dei principali temi oggetto di discussione nel dibattito scientifico sulla giustizia penale internazionale e, tenendo conto anche del contesto geopolitico, si articolano secondo tre aree tematiche: l’esercizio della giurisdizione penale (universale) sui crimini internazionali, la responsabilità individuale e il nodo delle immunità, la definizione dei crimini contro l’umanità e le sanzioni. Questa pubblicazione si pone a conclusione del Progetto di formazione di eccellenza “La giustizia penale internazionale nella prospettiva italiana”, promosso dalla Fondazione Centro Nazionale di Prevenzione e Difesa Sociale-CNPDS/ISPAC in collaborazione con il Dipartimento di Scienze Giuridiche “Cesare Beccaria” e finanziato dal Ministero della Giustizia – Dipartimento per gli affari di giustizia. Il volume è a cura dei responsabili scientifici del Progetto di formazione di eccellenza, Stefano Manacorda, professore ordinario di diritto penale presso l’Università degli Studi della Campania “Luigi Vanvitelli”, e Chantal Meloni, professoressa associata di diritto penale presso l’Università degli Studi di Milano
Who`s My Neighbour?
No full textThe EU is approaching bordering countries offering them Òneighbourhood relationsÓ, but it fails short of taking into consideration how this concept may be perceived by its partners. This paper will propose a reconsideration of the term ÒneighbourÓ in the conviction that this operation is of fundamental importance in order to solve any eventual misunderstanding on its meaning and to define, in the context of the ENP, what the nature of a relationship of neighbourhood may imply. In particular, it will look at the literature to show that this term, far from being uncontested, fundamentally implies an ÒotheringÓ practice which transcends the Christian teaching to Òlove oneÕs neighbour as oneselfÓ. Then, it will underline that this word may have different connotations in partner countries which may go beyond a neutral indication of geographical proximity and which may not correspond to the meaning consolidated in the Anglo Saxon tradition which basically refers to a neighbour as to a ÒfellowÓ. Finally, the paper will underline that the same fundamental ambiguity which marks the term here considered lies at the very core of the ENP. As a matter of fact, this policy shows persisting uncertainties on how to substantiate the relationship with neighbouring countries, whether in terms of fellowship and integration or in terms of an Òother than meÓ who still represents a security threat.Neighbourhood, ENP, integration-security dilemma
Molecular and solid-state (8-hydroxy-quinoline)aluminum interaction with magnesium: A first-principles study
No full textThe interaction between Mg and (8-hydroxyquinoline)aluminum, Alq(3), is investigated via ab initio molecular dynamics based on density-functional theory. We model the Alq(3) thin film both with a single Alq(3) molecule in vacuo (as is usually done in the literature) and with an Alq(3) crystalline structure. Comparing the results from these two models, we show that bulk calculations provide a better description of the chemical processes involved, allowing the Mg atom to react with two neighboring Alq(3) molecules, as was alluded to in a previous publication [S. Meloni, A. Palma, A. Kahn, J. Schwartz, and R. Car, J. Am. Chem. Soc. 125, 7808 (2003)]. Moreover, core-level shift calculations are in good agreement with experimental measurements only when using the solid phase approach. We also propose a different interpretation of the Al(2p) experimental core level presented in a previous work [C. Shen, A. Kahn, and J. Schwartz, J. Appl. Phys. 89, 449 (2001)]
Simulation-optimization under uncertainty through metamodeling and bootstrapping
No full textMost methods in simulation-optimization assume known environments, whereas this research accounts for uncertain environments combining Taguchi's world view with either regression or Kriging (Gaussian Process) metamodels (response surfaces). These metamodels are combined with Non-Linear Mathematical Programming (NLMP) to find a robust optimal solution. Varying the constraint values in the NLMP model gives an estimated Pareto frontier. To account for the variability of the estimated Pareto frontier, this research uses bootstrapping which gives confidence regions for the robust optimal solution. This methodology is illustrated through the Economic Order Quantity (EOQ) inventory-management model, accounting for the uncertainties in the demand rate and the cost coefficients
Nucleation of silicon nanoparticles in amorphous silicon dioxide matrices
No full textIn this contribution I summarize our research on the formation of nanoparticles embedded in a‐SiO2−x matrices. In particular, I focus on the Si diffusion in SiO2−x matrices, and amorphous-to-crystalline phase transition in Si nanoparticles embedded in SiO2−x. I show that Si diffusion can be rationalized in terms of three mechanisms: O-driven (i.e. driven by the change of O-coordination), Si-driven, and bond-swapping (i.e. driven by the change of "local" stoichiometry). The relevance of each of these mechanisms depends on the silicon concentration in the sample and on the temperature. The O-driven mechanism dominates at low Si concentrations, and Si-driven and bond-swapping dominate at higher ones. At higher T the effect is mitigating the difference of contribution among the various mechanisms. Concerning amorphous-to-crystalline phase transition, I show that in small nanoparticles (radius ≤ 2 nm) the more stable phase at low Ts is the amorphous one, i.e. there is an inversion of the relative stability between the two phases with respect to bulk systems. In larger nanoparticles the bulk-like behavior is recovered. High temperatures favors the crystal phase in small nanoparticles. These results can explain the experimental observations that nanoparticles undergo to a phase transition in preparation protocol adopting "high" annealing temperatures (T ≥ 1150 °C)

Use of interleukin-2 in the management of haematological malignancies: focus on minimal residual disease. Mandelli F, Capria S, Vignetti M, Meloni G.
No full textInterleukin (IL)-2 is a glycoprotein lymphokine which induces proliferation of all subclasses of T-lymphocytes, natural killer cells and lymphokine activated killer cells, differentiation of cytotoxic cells and secretion of other cytokines, especially interferon-gamma. A fundamental property of IL-2 activated effector cells is to selectively lyse freshly isolated tumour cells. Work carried out on animal tumour models and application in human therapeutics has suggested the potential value of an immunotherapeutic approach in haematological malignancies, especially in the setting of minimal residual disease. Extensive phase I/II trials have been conducted in all haematological diseases, but the most interesting results have been obtained in acute myeloid leukaemia and non-Hodgkin's lymphoma, where the possibility of achieving partial and complete responses in patients with advanced disease has been reported. The feasibility and immunomodulatory effects of IL-2 treatment in patients with minimal residual disease after high-dose chemotherapy have also been explored. However, the heterogeneity of cases treated and administration schedules used does not allow definitive conclusions to be drawn about the true impact of IL-2 treatment on the prognosis of these patients. The clearly encouraging results reported in the literature deserve further investigation from a biological and clinical point of view; until the role of IL-2 in haematological malignancies has been identified, it should be used only in the investigative setting of clinical trials
