Discontinuous Galerkin computation of the Maxwell eigenvalues on simplicial meshes
No full textAbstractThis paper is concerned with the discontinuous Galerkin approximation of the Maxwell eigenproblem. After reviewing the theory developed in [A. Buffa, I. Perugia, Discontinuous Galerkin approximation of the Maxwell eigenproblem, Technical Report 24-PV, IMATI-CNR, Pavia, Italy, 2005 〈http://www.imati.cnr.it/∼annalisa/PS/maxwell.pdf〉], we present a set of numerical experiments which both validate the theory, and provide further insight regarding the practical performance of discontinuous Galerkin methods, particularly in the case when non-conforming meshes, characterized by the presence of hanging nodes, are employed

Principessa o cantante? Il Congresso di Verona, l’opera buffa e la politica di Alessandro I
No full textRiassunto: L’articolo è dedicato all’analisi dei festeggiamenti di corte organizzati a Verona durante il Congresso dei monarchi europei. In particolare l’autore si sofferma su un curioso e misterioso episodio avvenuto in un palazzo veronese alla fine di novembre del 1822, dove l’imperatore Alessandro I allestì una rappresentazione dell’opera buffa La molinara di Giovanni Paisiello in cui cantò una famosa femme de lettres russa, la principessa Zinaida Volkonskaja. Secondo l’ipotesi dell’autore, questa rappresentazione non soltanto ebbe un significato culturale, ma conteneva un importante messaggio politico e religioso rivolto agli altri sovrani presenti al congresso.
Abstract: The aim of the article is to analyze the court festivities organized in Verona during the Congress of European Monarchs. In particular, the author dwells on a curious and mysterious episode that took place in a Verona palace at the end of November 1822, where Emperor Alexander I staged a performance of the opera buffa La molinara by Giovanni Paisiello, in which the famous Russian femme de lettres Princess Zinaida Volkonskaya sang. According to the author’s hypothesis, this performance not only had cultural significance, but contained also an important political and religious message addressed to the other sovereigns attending the congress.

Amphibolothrips Buffa 1909
No full text<i>Amphibolothrips</i> Buffa <p> <i>Amphibolothrips</i> Buffa, 1909: 193. Type species <i>Amphibolothrips grassii</i> Buffa.</p> <p> <i>Bebelothrips</i> Buffa, 1909: 195. Type species <i>Bebelothrips latus</i> Buffa. <b>Syn.n</b></p> <p> <i>Conocephalothrips</i> Bianchi, 1946: 499. Type species <i>Conocephalothrips tricolor</i> Bianchi. <b>Syn.n.</b></p> <p> Buffa (1909) erected this genus for a single species, <i>grassii</i>, based on a single specimen from Lake Albano near Rome, in Italy. This species is currently recorded also from southern France and Spain. In the same paper, Buffa also erected <i>Bebelothrips</i> for a single species, <i>latus</i>, based on three females from Isola del Giglio, an island between the west coast of Italy and Corsica. The original specimens of both species are currently not known to exist, however <i>Trachythrips flavicinctus</i> Bournier from southern France is now considered a synonym of <i>latus</i>. The genus <i>Bebelothrips</i> has remained distinguished from <i>Amphibolothrips</i> based only on the differing number of antennal segments (Priesner 1964). However, despite the larger number of antennal segments, Stannard (1970) transferred <i>Trachythrips marginatus</i> Bournier from southern France to <i>Amphibolothrips</i>, and Mound (1972) similarly transferred <i>Bebelothrips knechteli</i> Priesner, a species that is recorded only from Romania and the Canary Islands.</p> <p> Bianchi (1946) erected <i>Conocephalothrips</i> for the single species <i>tricolor</i>, and this remains known only from two females collected on Oahu. The new genus was compared only to <i>Urothrips</i> and no mention was made of <i>Amphibolothrips</i> although the head of <i>grassii</i>, the only species of the genus known at that time, is similarly produced forward over the antennal bases (Figs 21–25). The antennal segments of <i>grassii</i> are more extensively fused than in <i>tricolor</i>, in which antennal segments III–V are distinct but broadly joined (Figs 1–3). The antennae of <i>Bebelothrips latus</i>, and also of the other two species now placed in <i>Amphibolothrips</i>, are intermediate in structure between <i>grassii</i> and <i>tricolor</i>. The body of the holotype of <i>tricolor</i> has too much pigment for basantra to be visible, but the species is unusual in having the dorsal pair of anal setae flattened and scale-like, and less than 10 microns long.</p> <p> It is not possible to know if the species <i>tricolor</i> is a natural inhabitant of the Hawaiian Islands, or if it has been introduced to Oahu from some other part of the world. In the northern part of North America almost nothing is known of the leaf litter thrips fauna, but the other four species here recognised in <i>Amphibolothrips</i> are all from the southern parts of Europe. However, despite the interpretation adopted here of the available data, there is a further problem in distinguishing <i>Amphibolothrips</i> from <i>Urothrips</i>. The distinction between these indicated above in the key to genera fails with just one of the 12 described species of <i>Urothrips</i>. The fore tarsal hamus of <i>calvus</i> from eastern China appears to be absent, although it is also very small in <i>lancangensis</i> from southern China.</p> <p> The new synonymy of <i>Bebelothrips</i> and <i>Conocephalothrips</i> with <i>Amphibolothrips</i> results in two new combinations as listed in Table 1.</p>Published as part of <i>Mound, Laurence A., Lima, Élison Fabrício B. & O'Donnell, Cheryle A., 2023, What is a genus-interpreting structural diversity among species of urothripine Phlaeothripinae (Thysanoptera), pp. 91-102 in Zootaxa 5319 (1)</i> on pages 97-98, DOI: 10.11646/zootaxa.5319.1.6, <a href="http://zenodo.org/record/8182213">http://zenodo.org/record/8182213</a>
Inner City Blues: Blues Legacies and the Roots of 1968
No full textIn this article, I would like to propose an alternative and long view of the “1968” which is grounded in Black liberation movements, Afrodiasporic cultures, neighborhood-based organizations and sustained and propagated by music and sound. Venturing into this alternative history, I consider the Bronx, Harlem and Naples, Italy, as networks of resistance and nodal junctures for the transmission of Afrodiasporic cultures of opposition. Connecting the mutual influence of global social movements, music and neighborhood-based organizations, my article is also an invitation to start thinking about history through acoustic/musical resonances
