Hybrid architecture for shape reconstruction and object recognition
1998
The proposed architecture is aimed to recover 3-D- shape information from gray-level images of a scene; to build a geometric representation of the scene in terms of geometric primitives; and to reason about the scene. The novelty of the architecture is in fact the integration of different approaches: symbolic reasoning techniques typical of knowledge representation in artificial intelligence, algorithmic capabilities typical of artificial vision schemes, and analogue techniques typical of artificial neural networks. Experimental results obtained by means of an implemented version of the proposed architecture acting on real scene images are reported to illustrate the system capabilities.
On john maynard keynes's anti-semitism once again: A documentary note
2015
This note presents new archival evidence about John Maynard Keynes' attitudes toward Jews. The relevant material is composed of two letters sent by Robert G. Wertheimer to Bertrand Russell and Richard F. Kahn along with their replies. Between 1963 and 1964, Wertheimer - An Austrian-born Jewish immigrant then professor of economics at Babson College - wrote to Russell and Kahn asking for their personal reminiscences concerning Keynes' anti-Semitic utterances. In their brief but still significant responses, both Russell and Kahn firmly denied any hint of anti-Semitism in Keynes, thereby providing significant first-hand testimonies from two of his closest acquaintances.
Pharmacological blockade of the fatty acid amide hydrolase (FAAH) alters neural proliferation, apoptosis and gliosis in the rat hippocampus, hypothal…
2015
Endocannabinoids participate in the control of neurogenesis, neural cell death and gliosis. The pharmacological effect of the fatty acid amide hydrolase (FAAH) inhibitor URB597, which limits the endocannabinoid degradation, was investigated in the present study. Cell proliferation (phospho-H3(+) or BrdU(+) cells) of the main adult neurogenic zones as well as apoptosis (cleaved caspase-3(+)), astroglia (GFAP(+)), and microglia (Iba1(+) cells) were analyzed in the hippocampus, hypothalamus and striatum of rats intraperitoneally treated with URB597 (0.3 mg/kg/day) at one dose/4-days resting or 5 doses (1 dose/day). Repeated URB597 treatment increased the plasma levels of the N-acylethanolamine…
Temperature-related mortality impacts under and beyond Paris Agreement climate change scenarios.
2018
The Paris Agreement binds all nations to undertake ambitious efforts to combat climate change, with the commitment to hold warming well below 2 degrees C in global mean temperature (GMT), relative to pre-industrial levels, and to pursue efforts to limit warming to 1.5 degrees C. The 1.5 degrees C limit constitutes an ambitious goal for which greater evidence on its benefits for health would help guide policy and potentially increase the motivation for action. Here we contribute to this gap with an assessment on the potential health benefits, in terms of reductions in temperature-related mortality, derived from the compliance to the agreed temperature targets, compared to more extreme warmin…
Il Potere dei Privati sul Corpo tra Indisponibilità e Autodeterminazione
2011
Il contributo descrive l’evoluzione del sistema giuridico in materia di atti di disposizione del corpo dal periodo antecedente all’emanazione del codice civile del 1942 ad oggi. Il mutamento segnato dalla Costituzione repubblicana del 1948 e, a livello sovranazionale, dalla recente Carta dei diritti fondamentali dell’Unione Europea (entrata in vigore nel dicembre del 2009) registra il passaggio da una tendenziale indisponibilità del corpo, fondata sul divieto di atti cagionanti una diminuzione permanente dell’integrità fisica del disponente o altrimenti contrari alla legge, all’ordine pubblico o al buon costume posto all’art. 5 del codice civile, al riconoscimento di una libertà del soggett…
Gli atti di disposizione
2013
Il saggio prende in esame la disciplina degli atti di disposizione del proprio corpo nella prospettiva del limite che essa pone all'autonomia dei privati, scrutinandone il significato e la portata attuali alla luce dei mutamenti intervenuti nel sistema, dopo il varo dell'art. 5 del codice civile, anche per effetto della normativa comunitaria e, in particolare, della Carta dei diritti fondamentali dell'Unione europea. Specola privilegiata di indagine sono le previsioni in materia di consenso nelle fattispecie dispositive di organi, di cellule e tessuti umani a destinati ad applicazioni (trapianto, innesto, infusione) su soggetti terzi. Nel persistente richiamo della normativa di settore a li…
Autorità Indipendenti e soft law. Forme, contenuti, limiti e tutele.
2018
è una monografia scientifica che vuole indagare il fenomeno della soft law, limitando il campo di indagine ad alcune Autorità Indipendenti che. per la loro autorevolezza e per l’importanza dei settori cui sono proposte, si sono imposte nel panorama italiano. In particolare lo studio evidenzia come esse, attraverso i loro atti spesso non dotati di efficacia formalmente vincolante, siano in grado di intervenire nel sistema delle fonti in modo significativo. Ciò accade perché il legislatore pare aver scelto di abbandonare il campo di gioco in settori molto rilevanti dal punto di vista economico e sociale e caratterizzati da alta tecnicità, delegando a questi organismi la loro governance genera…
Improving accuracy of FIR filters for computing convolution transforms for smooth non-bandlimited signals
2019
We propose to improve the accuracy of FIR filters for computing convolution transforms for smooth non-bandlimited (NBL) signals by designing filters by the identification method with using a pair of bandlimited portions of the chosen NBL input and output signals related with each other by the given transform. A design example of type IV linear phase differentiator is presented, where filter coefficients are calculated from the bandlimited portions of the Cauchy pulse and its derivative. The performance of the designed differentiator is evaluated by comparing the accuracy of computed derivatives for several smooth NBL test signals, such as the Cauchy pulse, the Hilbert transform of Cauchy pu…
An attempt to realise the constrained search approach in the density functional theory
2001
Abstract The problem of reconstruction of wave functions from a given electron density is considered. A reformulation of the problem is proposed which is based on the Fourier transform. Arising mathematical problems are studied, namely, the properties of reduced spatial densities and their Fourier images are obtained, which follow from known properties of the wave functions. The proposed approach may provide a practical implementation of the Constrained Search Approach to the DFT.
Petrogenetic evolution of metabasalts and metakomatiites of the lower Onverwacht Group, Barberton Greenstone Belt (South Africa)
2019
A well-preserved sequence, by Archean standards, of mantle-derived metabasalts and metakomatiites forms large parts of the lower Onverwacht Group of the Barberton Greenstone Belt (South Africa). To elucidate the origin of mafic and ultramafic rocks from this 3.55 to 3.45 Ga sequence, we present a comprehensive geochemical dataset including major and trace elements as well as Lu-Hf and Sm-Nd isotope compositions for a variety of metavolcanic rocks. These include metabasalts of the amphibolite-facies Sandspruit and Theespruit Formations as well as metabasalts and metakomatiites of the lower greenschist-facies Komati Formation. Based on their incompatible trace element patterns, the basalts of…
