Nei nostri tempi si sviluppa un nuovo metodo di eseguire il canto gregoriano, ispirato al lavoro di E. Cardine, Semiologie Grégorienne (Extrait des Etudes Grégoriennes, Tome XI), Solesmes 1970, ma anche alla pratica di canto da parte dei monaci orientali e dei cantori dalle isole del Mar Mediterraneo. Le spiegazioni della ricca tradizione di Solesmes vengono messe in discussione. Nel pressus i cantori fanno la ripercussione delle note colla stessa altezza, spesso in modo nervoso. Si cerca di badare tutti i dati degli antichi manoscritti e di eseguire esattamente i più piccoli segmenti, a scapito di frasi più grandi e d’insieme di un canto. Interessanti sono gli studi sul trattato di Girolamo di Moravia, ma bisogna sapere che questo è una fonte del canto del XIII secolo, autentico solo per l’Ordine dei Predicatori. Dal IX secolo molti musicisti s’interessavano più alla primitiva musica polifonica che al monodico canto gregoriano. Sarebbe bene studiare gl’influssi orientali sul canto della Chiesa latina e i costumi dei monaci e dei cantori diocesani dei duomi e delle collegiate nel medioevo per conoscere meglio le autentiche tradizioni, ma è una cosa per gli specialisti; gli elementi orientali interessano solo i giovani musicisti e quelli più maturi. Invece nella pratica quotidiana del canto gregoriano importante è che ciascuno brano venga eseguito con i suoi dati specifici senza mescolanza e sincretismo e poi le cose concrete come: la conoscenza del senso dei testi liturgici latini, l’altezza commoda per i cantori, il tempo moderato, non troppo lento e non troppo veloce, il modo normale di cantare dei solisti e dei gruppi.

AbstractWe investigate the implications of transverse homoclinic orbits to fixed points in dissipative diffeomorphisms of the annulus. We first recover a result due to Aronsonet al.[3]: that certain such ‘rotary’ orbits imply the existence of an interval of rotation numbers in the rotation set of the diffeomorphism. Our proof differs from theirs in that we use embeddings of the Smale [61] horseshoe construction, rather than shadowing and pseudo orbits. The symbolic dynamics associated with the non-wandering Cantor set of the horseshoe is then used to prove the existence of uncountably many invariant Cantor sets (Cantori) of each irrational rotation number in the interval, some of which are shown to be ‘dissipative’ analogues of the order preserving Aubry-Mather Cantor sets found by variational methods in area preserving twist maps. We then apply our results to the Josephson junction equation, checking the necessary hypotheses via Melnikov's method, and give a partial characterization of the attracting set of the Poincaré map for this equation. This provides a concrete example of a ‘Birkhoff attractor’ [10].

AbstractThe resonant structure near a noble cantorus is found. Islands of stability are located near the gaps of the cantorus. The crossing of the gaps of the cantorus by the asymptotic curves of unstable periodic orbits is shown numerically (non-schematically). We discuss how these structures influence stickiness.

In His Review essay on “Civil Society, Liberalism and the Corporatist Alternative in the Middle East,” Louis J. Cantori continues his indefatigable promotion of corporatism as a lens for understanding Middle East politics. Lou and I have been friends for many years, and I know that I probably will not be able to shake his deep attachment to corporatism. Nonetheless, since the inspiration for his latest peroration was the two volume collection on civil society in the Middle East that I edited, I thought readers of the Bulletin might be interested in my response to his assertions.

We study analytically and numerically the thermoelectric properties of a chain of cold atoms with dipole-dipole interactions placed in an optical periodic potential. At small potential amplitudes the chain slides freely that corresponds to the Kolmogorov-Arnold-Moser phase of integrable curves of a symplectic map. Above a certain critical amplitude the chain is pinned by the lattice being in the cantori Aubry phase. We show that the Aubry phase is characterized by exceptional thermoelectric properties with the figure of merit Z T = 25 being 10 times larger than the maximal value reached in material science experiments. We show that this system is well accessible for magneto-dipole cold atom experiments that opens new prospects for investigations of thermoelectricity.

Chaotic transport in a time-periodic flow with a chain of vortices bounded by two jet regions is numerically studied using the separatrix map. The stickiness of invariant surfaces in the jet regions produces long flights of tracer particles which leads to anomalous diffusion and the algebraic decay in the probability distributions for flight lengths. For a set of parameter values of the separatrix map explored, we found crossovers in the algebraic decay, which take place at time scales for a particle to penetrate the cantori leading to the large fluctuation of the algebraic exponents and the change in the nature of diffusion at various time scales. The relation between the exponents for flights and anomalous diffusion is discussed in connection with a continuous-time random walk model, and is compared with the results from numerical experiments.

AbstractTwo simple and efficient numerical methods to explore the phase space structure are presented, based on the properties of the “dynamical spectra”. 1) We calculate a “spectral distance”Dof the dynamical spectra for two different initial deviation vectors.D→ 0 in the case of chaotic orbits, whileD→const≠ 0 in the case of ordered orbits. This method is by orders of magnitude faster than the method of the Lyapunov Characteristic Number (LCN). 2) We define a sensitive indicator called ROTOR (ROtational TOri Recongnizer) for 2D maps. The ROTOR remains zero in time on a rotational torus, while it tends to infinity at a rate ∝N= number of iterations, in any case other than a rotational torus. We use this method to locate the last KAM torus of an island of stability, as well as the most important cantori causing stickiness near it.

AbstractWe study a process of stochastization of the motions in an example of the Henon-Heiles model. We propose a new method to study this process a method of the field of directions of motion in the meridional plane. A numerical integration of the equation for the derivative of this field ∂f/∂n to the normal to a trajectory has been made. We denote the points in which ∂f/∂n → ± ∞, and derive the contours of orbit and folds of directions. The growth of ergodity is connected with the increase of a number and an area of the folds. May be, a successive doubling of a number of folds takes place that results in a chaos. In the transition region we found a complex periodical orbit. The interpretation of this fact may be made as an example of cantori. A transition region has very small sizes about 10−4

Riassunto: Il saggio è un contributo alla vexata quaestio sull'origine dell'ottava rima narrativa. Si riflette su importanti spunti di Surdich e su dati noti per ipotizzare un'imitazione del metro del Cantare di Fiorio da parte del Boccaccio, che utilizza negli stessi anni nel Filocolo lo stesso tema romanzesco del Cantare e nel Filostrato l'ottava narrativa. Le operazioni inverse delle due opere giovanili rispetto al Cantare di Fiorio si aggiungono a molti altri elementi speculari nelle due opere boccacciane. Immaginare che l'autore del Cantare di Fiorio o chi per lui accogliesse il metro di nuova invenzione istantaneamente, adattandolo a esigenze espressive molto dissimili da quelle del Filostrato e calandovi una sintassi semplificata diversissima da quella delle ottave di Boccaccio, significa ritenere possibile un'operazione problematica per un genere tradizionale e conservativo come quello dei cantari. Che al contrario l'appropriazione del metro e di alcuni pochi tratti espressivi del cantare da parte del Boccaccio potesse costare all'autore una fatica modesta lo testimonia tutta o quasi la sua produzione. Come ha sottolineato Balduino nello stabilire la tradizione da cui dipende l'ottava rima cosí come la utilizzano i cantari è cogente l'esigenza di situarla in un contesto culturale "popolare", in cui la forma metrica sia legata all'esecuzione orale, a caratteristiche di generi come il serventese, a una temperie caratteristica e a un repertorio linguistico e formulare secolari. Se è imprescindibile tener conto di precise coordinate socioculturali per interpretare l'opera degli autori come lo sviluppo dei generi e delle forme, nel medioevo in particolare, categorie come popolare e colto non vanno intese in senso assoluto ma andrebbero utilizzate come valori scalari e relativi. Nonostante accostamenti possibili tra l'operato del Boccaccio e i cantari è evidente che i cantari sono da ascrivere un ambito per lo piú semicolto, mentre nelle opere in ottava rima del Certaldese intravediamo un autore che desidera appropriarsi delle tradizioni in cui si imbatte e segnare tali esperienze nobilitandole. Parole chiave: vexata quaestio, ottava rima, cantari, Boccaccio, Filostrato, Filocolo, Cantare di Fiorio e Biancifiore, popolare, colto. Abstract: The essay is a contribution to the vexata quaestio of the origin of ottava rima. Some important ideas of Surdich and known data are discussed to hypothesize Boccaccio's imitation of Cantare di Fiorio's meter. The author used in the same years in the Filocolo the topic of the Cantare and in the Filostrato the ottava rima. The inverse operations with respect to the Cantare di Fiorio are added to many other specular elements in Boccaccio's juvenile works. To imagine that the Cantare di Fiorio's author or someone else could welcome the meter of new invention instantly, adapting it to requirements very different from Filostrato's, with a simplified syntax very different from that of Boccaccio's ottave is very problematic for a conservative and traditional genre like that of cantari. On the contrary, the appropriation of the meter and few expressive features by Boccaccio might've been a modest effort, as his literary production attests. As underlined by Balduino, in establishing the tradition of ottava rima used in the cantari it's imperative to place it in a "popular" context, with a secular repertoire; the metrical form has to be connected to the performance, to genres as serventese. To interpret authors' works and the development of literary genres and forms it's essential to take into account precise socio-cultural coordinates, but we can anyway remember that in the Middle Ages in particular, categories as popular and cultured should be used as scalar and relative values. It's possible to put Boccaccio and the cantari side by side, but these last are to be ascribed most of the times to a semieducated literary field, instead Boccaccio's poems in ottava rima show an author who wishes to appropriate the traditions in which he comes across ennobling them. Keywords: vexata quaestio, ottava rima, cantari, Boccaccio, Filostrato, Filocolo, Cantare di Fiorio e Biancifiore, popular, cultured.

Stickiness refers to chaotic orbits that stay in a particular region for a long time before escaping. For example, stickiness appears near the borders of an island of stability in the phase space of a 2-D dynamical system. This is pronounced when the KAM tori surrounding the island are destroyed and become cantori (see [Contopoulos, 2002]). We find the time scale of stickiness along the unstable asymptotic curves of unstable periodic orbits around an island of stability, that depends on several factors: (a) the largest eigenvalue |λ| of the asymptotic curve. If λ > 0 the orbits on the unstable asymptotic manifold in one direction (fast direction) escape faster than the orbits in the opposite direction (slow direction) (b) the distance from the last KAM curve or from the main cantorus (the cantorus with the smallest gaps) (c) the size of the gaps of the main cantorus and (d) the other cantori, islands and asymptotic curves. The most important factor is the size of the gaps of the main cantorus. Then we find when the various KAM curves are destroyed. The distance of the last KAM curve from the center of an island gives the size of the island. When the central periodic orbit becomes unstable, chaos is also formed around it, limited by a first KAM curve. Between the first and the last KAM curves there are still closed invariant curves. The sizes of the islands as functions of the perturbation, have abrupt changes at resonances. These functions have some universal features but also some differences. A new type of stickiness appears near the unstable asymptotic curves of unstable periodic orbits that extend far into the large chaotic sea. Such a stickiness lasts for long times, increasing the density of points close to the unstable asymptotic curves. However after a much longer time, the density becomes almost equal everywhere outside the islands of stability. We consider also stickiness near the asymptotic curves from new periodic orbits, and stickiness in Anosov systems and near totally unstable orbits. In systems that allow escapes to infinity the stickiness delays the escapes. An important astrophysical application is the case of barred-spiral galaxies. The spiral arms outside corotation consist mainly of sticky chaotic orbits. Stickiness keeps the spiral forms for times longer than a Hubble time, but after a much longer time most of the chaotic orbits escape to infinity.

We study the motion of non-diffusive, passive particles within steady, three-dimensional vortex breakdown bubbles in a closed cylindrical container with a rotating bottom. The velocity fields are obtained by solving numerically the three-dimensional Navier–Stokes equations. We clarify the relationship between the manifold structure of axisymmetric (ideal) vortex breakdown bubbles and those of the three-dimensional real-life (laboratory) flow fields, which exhibit chaotic particle paths. We show that the upstream and downstream fixed hyperbolic points in the former are transformed into spiral-out and spiral-in saddles, respectively, in the latter. Material elements passing repeatedly through the two saddle foci undergo intense stretching and folding, leading to the growth of infinitely many Smale horseshoes and sensitive dependence on initial conditions via the mechanism discovered by šil'nikov (1965). Chaotic šil'nikov orbits spiral upward (from the spiral-in to the spiral-out saddle) around the axis and then downward near the surface, wrapping around the toroidal region in the interior of the bubble. Poincaré maps reveal that the dynamics of this region is rich and consistent with what we would generically anticipate for a mildly perturbed, volume-preserving, three-dimensional dynamical system (MacKay 1994; Mezić & Wiggins 1994a). Nested KAM-tori, cantori, and periodic islands are found embedded within stochastic regions. We calculate residence times of upstream-originating non-diffusive particles and show that when mapped to initial release locations the resulting maps exhibit fractal properties. We argue that there exists a Cantor set of initial conditions that leads to arbitrarily long residence times within the breakdown region. We also show that the emptying of the bubble does not take place in a continuous manner but rather in a sequence of discrete bursting events during which clusters of particles exit the bubble at once. A remarkable finding in this regard is that the rate at which an initial population of particles exits the breakdown region is described by the devil's staircase distribution, a fractal curve that has been already shown to describe a number of other chaotic physical systems.

Este estudo tem como tema o desenvolvimento de programas de condicionamento vocal individualizado para a demanda específica de três profissionais da voz cantada. Trata-se de um relato de caso de três profissionais da voz cantada: uma cantora e atriz de teatro musical brasileiro, um cantor sertanejo e um cantor de roque. Os três indivíduos foram submetidos à avaliação fonoaudiológica, apresentando queixas relacionadas a cansaço e fadiga após uso da voz e/ou aperfeiçoamento vocal e realizaram avaliação otorrinolaringológica prévia. Os três pacientes estavam em processo de terapia fonoaudiológica, sendo uma das etapas o desenvolvimento de um programa de condicionamento vocal individualizado, de acordo com a demanda, necessidade e disponibilidade de cada sujeito. A cantora e atriz de teatro musical brasileiro aderiu facilmente à proposta personalizada de condicionamento vocal, pois sentia os ganhos de realização uma mobilização fisiológica antes de passar para a técnica-artística que já executava. O cantor sertanejo aderiu facilmente ao programa de condicionamento vocal individualizado, sem nenhuma dificuldade, e relatou extrema melhora em seu conforto e desempenho vocal durante o canto com os exercícios selecionados. O cantor de roque apresentou maior flexibilização de trato vocal, estabilidade da emissão no canto, ampliação da tessitura vocal, maior precisão articulatória e redução da constrição global excessiva após dar início ao programa de condicionamento vocal individualizado.O condicionamento vocal individualizado mostra efeitos positivos, principalmente para os profissionais da voz, pois os indivíduos trabalham exatamente sob a demanda que será utilizada com o uso profissional da voz,com exercícios específicos e direcionados para suas necessidades.

We study generic effects on the quantum dynamics of classical trapping-leaking mechanism by investigating in detail the 2δ-kicked rotors whose classical phase space is partitioned into momentum cells separated by trapping regions which slow down the motion. We focus on a range of parameters where the dynamics is generic, namely, the phase space has no stable islands. As a consequence of the trapping-leaking mechanism, we show that the classical motion is described by a process of anomalous diffusion. We investigate in detail the impact of the underlying classical anomalous diffusion on the quantum dynamics with special emphasis on the phenomenon of dynamical localization. Based on the study of the quantum density of probability, its second moment and the return probability, we identify a region of weak dynamical localization where the quantum diffusion is still anomalous but the diffusion rate is slower than in the classical case. Moreover, we examine how other relevant time scales, such as the quantum-classical breaking time and the one related to the beginning of full dynamical localization, are modified by the classical anomalous diffusion. Finally, we discuss the relevance of our results for understanding the role of classical cantori in quantum mechanics.

Ao refletirmos sobre a figura do intérprete na canção popular é natural elegermos algumas personalidades em detrimento a outras. Uma justificativa simplória, imediata, estaria calcada na questão da emoção. A interpretação de um cantor emociona mais porque é “verdadeira”, sugere “domínio da cena”, faz parecer que o cantor “vive” a canção, “sente” a música garantindo um lugar diferenciado aos intérpretes. Este artigo teve por objetivo discutir o processo de interpretação em “Tiro de Misericórdia” (João Bosco e Aldir Blanc) na leitura da cantora Titane. Como um estudo exploratório, descritivo, foi feita uma entrevista com a artista, buscando identificar e descrever seu processo criativo por meio da reelaboração da canção, construção da dramaticidade textual, corporal e vocal, do pensamento e do discurso assumido por ela. Observou-se que a escolha da canção é fator imperativo, já que o intérprete se apodera da obra moldando-a ao próprio corpo, numa habilidade que envolve o som e suas propriedades, sem prescindir de sua imaginação e inventividade contornados pela vivência e sua bagagem sociocultural.
