Gilles Tremblay pédagogue vu par ses anciens élèves
Authors: Trottier Danick 
Published: June 2012

Réalisée au mois de juin 2010 par l’entremise du courriel, l’enquête proposée ici vise à jeter un éclairage sur les classes d’analyse et de composition de Gilles Tremblay au Conservatoire de musique de Montréal. Neuf anciens étudiants de Tremblay, répartis sur plus de trois décennies, ont accepté de se prêter au jeu d’un retour dans le temps : Michel Gonneville, Gilbert Patenaude, Alain Lalonde, Louise Samson, André Villeneuve, Silvio Palmieri, Marc Hyland, Sean Pepperall et Annick-Patricia Carrière. Grâce à leur témoignage, on en sait aujourd’hui un peu plus sur l’organisation des cours de Tremblay. En outre, les anciens étudiants ont été interrogés sur les façons dont Tremblay structurait ses cours, la matière étudiée, les étapes franchies dans l’analyse des oeuvres, l’orientation dans le travail créatif, l’apport des collaborations externes, etc. En définitive, malgré la distance creusée par le temps, le souvenir reste vif et montre l’expérience singulière qui a pu se dégager dans le travail de guide auquel Tremblay le pédagogue s’est adonné. De sorte qu’on commence à peine à jauger le rôle fondateur qu’ont joué ses classes au sein de la modernité musicale québécoise.

Dans cette série de douze impressions, John Rea apporte son témoignage sur la vie et la musique de son ami, le compositeur Claude Vivier : l’intégration, chez lui, des objectifs artistiques, personnels et spirituels, la quête d’un enfant perdu à consoler, et le miroir autobiographique qu’a représenté sa musique.
Saison 1992-1993 : l’année de la nostalgie
Authors: Olivier Dominique 
Published: June 2012

Proposant comme à l’accoutumé un panorama critique de la saison montréalaise 1992-1993, l’auteure insiste sur ses caractéristiques marquantes : peu de jeunes compositeurs ont été joués; la nostalgie du déjà connu semble refléter l’angoisse actuelle de la société; pour des raisons idéologiques diverses, nos créateurs se sont beaucoup appuyés sur des textes littéraires et religieux. Une œuvre, cependant, surnage de ce marasme : L’adorable verrotière, de Serge Provost.
Dompter la mer sauvage
Authors: Couroux Marc 
Published: June 2012

Cet article fait état de la problématique des interprètes confrontés à des oeuvres « irréalisables » dans leur intégrité. La question est abordée sous les angles de la technique, de l’esthétique et de l’éthique. Face à diverses solutions proposées, l’interprète doit définir ses choix en s’appuyant sur une analyse de l’oeuvre qui lui permette d’en retrouver le sens.
Masques de l’identité
Authors: Pelinski Ramon 
Published: June 2012

Le musicologue et compositeur Ramon Pelinski étudie les propos de Kagel sur son œuvre Exotica du point de vue des stratégies compositionnelles, des structures et des attitudes perceptives qu’elle déclenche. Adoptant résolument le point de vue du postmodernisme et de l’actualisme, l’auteur traque les ambiguïtés de l’utilisation kagelienne de la musique « exotique » et analyse en détail quelle attitude elle implique quant à la conception de l’Autre
Requiem pour une fin de siècle
Authors: Masino Nicolas 
Published: June 2012

Se réjouissant de l’expansion de ce débat dans la presse, l’auteur revendique, devant la diversité des styles offerts, le droit d’aimer n’importe quel type de musique produite aujourd’hui. Il se refuse à considérer la musique contemporaine comme la seule grande musique de notre temps, il critique l’équation que font certains entre la complexité d’une oeuvre et sa « grandeur », et rejette le concept de continuité historique invoqué par Isabelle Panneton. Il voit dans la situation actuelle le signe de la fin de l’hégémonie géopolitique et culturelle de l’Europe où l’on a toujours voulu faire du neuf à tout prix. Il met sur le même plan les musiques pour piano de Nino Rota et de Debussy et regrette de ne pouvoir retenir un seul thème des oeuvres de Donatoni.

Traces d’écoutes : sur quelques tentatives historiennes de saisie du corps de la musique
Authors: Campos Rémy 
Published: June 2012

Les historiens de la musique qui ont essayé depuis une vingtaine d’années de décrire les anciennes manières d’entendre la musique se sont heurtés à une difficulté majeure : le peu de traces disponibles de cette activité à mesure que l’on remonte dans le temps. Il existait cependant des points d’observation que les chercheurs visitèrent quelquefois (journaux intimes, fragments de musique notés explicitement pour être « écoutés »). Mais l’obstacle le plus insurmontable n’était pas le déficit d’archives. Une forme sournoise d’anachronisme guettait en effet les mieux intentionnés des enquêteurs. Car se demander si les gens écoutaient la musique au XVIIIesiècle (William Weber) ou s’ils entendaient les exemples musicaux insérés dans les traités du XVIesiècle (Collins Judd dansReading Renaissance Music Theory) ne signifie pas forcément qu’on se soit départi de nos habitudes d’auditeurs modernes. Une réflexion sur l’histoire de l’écoute ne peut se dispenser de ce travail de mise à distance — comme l’indiquera la référence à l’histoire du livre et de la lecture (Chartier) —, quitte à déboucher sur des non-lieux de la pratique auditive.
Variations et variantes
Authors: Hétu Jacques , Beaucage Réjean 
Published: June 2012

Le compositeur Jacques Hétu revient sur l’expérience qualifiée de « choc » violent qu’a représenté pour lui l’enregistrement de ses Variations pour piano par Glenn Gould en 1967. Il rappelle, dans un premier temps, que ce musicien qui s’est exprimé essentiellement à travers l’interprétation rêvait aussi d’être compositeur. Il s’interroge sur la façon dont il « s’emparait parfois de la musique des autres et la transformait, parfois en la défigurant, parfois en la transfigurant ».
Il cible, à travers des exemples tirés de chacune des variations, les écarts de tempi, d’articulations, de dynamiques de même que les changements dans les jeux de pédale que s’est autorisé un Gould qui s’éloignait de plus en plus de la partition au fur et à mesure que l’oeuvre se déroulait.
Admettant que cette interprétation possède sa propre logique, Jacques Hétu salue en Gould un authentique créateur qui « nous communiquait impérieusement son propre univers de musicien ».
Le concept de complexité dans Cinquante ans de modernité musicale
Authors: Darbon Nicolas 
Published: June 2012

Cet article montre l’apport du livre de Célestin Deliège à la musicologie a) d’un point de vue strictement historique, puisque pour la première fois (hormis par R. Toop) est abordée de façon substantielle l’école de laNew Complexity; ce faisant, il « officialise » musicologiquement l’existence de cette école; b) par sa démarche critique, risquée, impliquée, Célestin Deliège rejoint quelques aspects de la pensée complexe d’Edgar Morin et de la Nouvelle Histoire. Cet article enfin n’est pas une simple apologie mais propose une réflexion succincte sur le concept clef de complexité pour les sciences et les arts contemporains.
Internal‐model‐based control to reject an external signal generated by a class of infinite‐dimensional systems
Authors: Quan Q. , Cai K.‐Y. 
Published: June 2012

SUMMARYIn this paper, an internal‐model‐based controller (IMBC) is designed to reject an external signal generated by a class of infinite‐dimensional systems for a class of nonlinear systems. First, a new description of the external signal is proposed. By this new description, the IMBC is designed, and the resulting closed‐loop error dynamics are analyzed with the help of a Lyapunov–Krasovskii functional. Compared with existing IMBCs, the designed IMBC provides the flexibility to cope with more types of external signals as well as to choose controller parameters to achieve a tradeoff between rejection performance and stability. Finally, the method is applied to attitude control of a quadrotor aircraft. Effectiveness of the IMBC is demonstrated by simulation. Copyright © 2012 John Wiley & Sons, Ltd.
Optimal design of reverse osmosis‐based water treatment systems
Authors: Karuppiah Ramkumar , Bury Scott J. , Vazquez Adriana , Poppe Gregg 
Published: June 2012

AbstractWe address the problem of optimal design of reverse osmosis (RO)‐based water treatment systems. A superstructure optimization method is proposed to solve the problem, where the superstructure for a RO system is structurally enhanced with additional features. We formulate the problem as mixed‐integer nonlinear program which is solved to yield optimal results. A case study on desalination is considered in this work, and the numerical results obtained using our approach are validated using a commercial simulation tool. We further extend the problem by considering the effects of degradation of membrane performance over time and solve it by representing the problem as a two‐stage stochastic program. This new approach is highly useful for identifying minimum cost robust designs for membrane‐based water purification systems, which are especially important in desalination applications. © 2012 American Institute of Chemical Engineers AIChE J, 2012
Radiographic density profiles link frontal and anterior ethmoid sinuses behavior in chronic rhinosinusitis
Authors: Sedaghat Ahmad R. , Bhattacharyya Neil 
Published: June 2012

AbstractBackground:Chronic rhinosinusitis (CRS) may occur through heterogeneous disease processes. It is possible that more than 1 inflammatory process underlies CRS in any given patient. If so, heterogeneity in processes may be a function of the spatial organization of the paranasal sinuses. Density characteristics of sinus opacities on computed tomography (CT) scans offer insight into the nature of sinus opacities and disease, in general, and may thus be used to detect spatial heterogeneity of sinus disease within a given patient.Methods:The study was a retrospective chart review of CRS patients with available sinus CT scans. Radiographic density profiles of sinus opacities were assessed by raw measures of densities (in Hounsfield units [HU]). Radiographic density profiles of the different affected sinuses were compared to each other, checked for correlation, and finally, checked for evidence of clustering using a principal component analysis.Results:Frontal sinus opacities appear to be more heterogeneous, with both higher and lower density components than other sinuses. There was strong correlation between the radiographic density profiles of opacities in the frontal, anterior ethmoid, and sphenoid sinuses (p < 0.001). However, on principal component analysis the radiographic density characteristics of the opacities of the frontal and anterior ethmoid sinuses appeared to cluster together more than the other sinuses.Conclusion:Radiographic properties of sinus opacities suggest the nature of sinus opacities are related not only to some common underlying pathology but also to factors related to the specific sinus as well as other spatially close affected sinuses. This suggests an anatomic orientation for sinus pathophysiology in CRS.
Organometallic Pt(II) containing polymer as silver protection against sulfide tarnishing
Authors: Fratoddi Ilaria , Marghella Giuseppe , Venditti Iole , Ferro Daniela , Russo Maria Vittoria 
Published: June 2012

AbstractIn this work, the use of a film of an organometallic polymer, namely Pt‐DEBP, has been tested for the selective capture of sulfides with the aim of protecting silver object. Ag foils were exposed to different environmental conditions in the presence of Pt‐DEBP films. Scanning electron microscopy, energy dispersive spectrometry, and colorimetric studies allowed to assess that the polymeric layer selectively captures H2S, preventing the tarnishing of the silver substrate over a period at least of 2 months, without any manipulation of the sample. This approach open new perspectives for the prevention of aging effects on silver objects of artistic interest, for which cleaning or coating procedures should be avoid. © 2012 Wiley Periodicals, Inc.

Investigation on some matrix‐dominated properties of hybrid multiscale composites based on carbon fiber/carbon nanotube modified epoxy
Authors: Wang Baichen , Zhou Xia , Yin Junshan , Wang Li 
Published: June 2012

AbstractContinuous fiber reinforced polymer‐based composites have outstanding fiber‐dominated properties but unsatisfactory matrix‐dominated performances. In this investigation, carbon fiber reinforced epoxy composites modified with carbon nanotubes (CNTs) were fabricated to evaluate the effects of CNTs on some matrix‐dominated properties of the resulting hybrid multiscale composites. Carboxylic acid functionalized multiwalled CNTs were dispersed in epoxy by using high energy sonication, followed by the fabrication of the composites laminates with the epoxy/CNTs dispersion. The dispersion quality of CNTs in epoxy and the capillary infiltration of continuous fiber with the epoxy/CNTs dispersion were characterized using optical microscope and capillary experiment to optimize the processing parameters. A CNTs loading of 1 wt % significantly improved the flexural strength and interlaminar shear strength of the composites containing varying scale reinforcements by 51.8% and 34.2%, respectively, as compared to the control carbon/epoxy composites. Scanning electron microscopy was used to examine the fracture surface of the failed specimens. The moisture absorption behavior of the carbon fiber/epoxy composites with and without CNTs was investigated by comparing the weight gain and shear properties degradation in distilled water and 1.5 wt % brine. The integration of CNTs in composites is found to contribute to the medium‐dependent moisture adsorption behavior. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
Identification of a major linear C1q epitope allows detection of systemic lupus erythematosus anti‐C1q antibodies by a specific peptide‐based enzyme‐linked immunosorbent assay

Published: June 2012

AbstractObjectiveAutoantibodies against C1q strongly correlate with the occurrence of severe nephritis in patients with systemic lupus erythematosus (SLE). We undertook this study to determine whether identification of the C1q epitope(s) recognized by these autoantibodies might lead to a better diagnostic assay and help elucidate the putative role of C1q and anti‐C1q in SLE.MethodsSLE patient–derived anti‐C1q Fab were used in a microarray‐based peptide scan to identify the peptide sequence recognized by anti‐C1q. Anti‐C1q Fab binding to the target peptide was further analyzed using real‐time interaction measurements (surface plasmon resonance) and peptide‐based enzyme‐linked immunosorbent assays (ELISAs).ResultsA peptide scan of the collagen‐like region of C1q identified 2 regions, 1 on the A chain and 1 on the B chain, that were the targets of the anti‐C1q Fab. Binding was confirmed by surface plasmon resonance and showed nanomolar affinity. The A chain–derived peptide could specifically be detected in a peptide‐based ELISA by SLE patient sera. Competition experiments suggested that this peptide represented one of the major linear epitopes of C1q that is the target of anti‐C1q in SLE. Serum antibodies from most SLE patients but not from healthy individuals specifically bound to this epitope. Binding to the peptide correlated with binding of the same sera to native C1q but was found to be more sensitive for the detection of lupus nephritis.ConclusionWe identified a major linear epitope of C1q that is the target of anti‐C1q in SLE. The ELISA using this peptide was more specific and more sensitive than a conventional anti‐C1q assay for the detection of active nephritis in SLE patients.
Increased expression of vascular cell adhesion molecule 1 in muscle biopsy samples from juvenile dermatomyositis patients with short duration of untreated disease is regulated by miR‐126

AbstractObjectiveTo evaluate the effect of duration of untreated disease on vascular cell adhesion molecule 1 (VCAM‐1) and microRNA (miRNA) expression in muscle biopsy samples from children with juvenile dermatomyositis (DM) as well as its effect on soluble VCAM‐1 (sVCAM‐1) and tumor necrosis factor α (TNFα) concentrations in sera from these children.MethodsWe enrolled 28 untreated children with juvenile DM and 8 pediatric controls. Eleven children with juvenile DM had short duration of untreated disease (symptoms for ≤2 months before muscle biopsy), and 17 had long duration of untreated disease (symptoms for >2 months before muscle biopsy). Vascular structures, characterized by immunofluorescence using antibodies against von Willebrand factor, VCAM‐1, and α‐smooth muscle actin, were measured for total area and intensity. Circulating sVCAM‐1 and TNFα levels were determined in patients with short duration of untreated disease, patients with long duration of untreated disease, and controls. Differential expression of microRNA‐126 (miR‐126) in muscle biopsy samples from the 2 patient groups and the control group was detected by miRNA expression profiling and confirmed by quantitative reverse transcription–polymerase chain reaction in muscle biopsy samples from the 3 groups.ResultsJuvenile DM patients with short duration of untreated disease had significantly higher total positive area and intensity/high power field of VCAM‐1 expression than did juvenile DM patients with long duration of untreated disease (P = 0.043 and P = 0.015, respectively) or controls (P = 0.004 and P = 0.001, respectively). Von Willebrand factor antigen–positive vasculature displayed greater VCAM‐1 intensity in patients with short duration of untreated disease than in patients with long duration of untreated disease (P = 0.001). Circulating levels of sVCAM‐1 and TNFα were significantly higher in patients with short duration of untreated disease than in controls (P = 0.013 and P = 0.048, respectively). The miRNA miR‐126, a negative regulator of VCAM‐1 expression, was significantly decreased (3.39‐fold; P < 0.006) in patients with short duration of untreated disease compared to controls, while miR‐126 expression in patients with long duration of untreated disease did not differ significantly compared to controls.ConclusionIn patients with short duration of untreated disease, miR‐126 down‐regulation is associated with increased VCAM‐1 in both muscle and blood, suggesting that VCAM‐1 plays a critical role early in juvenile DM disease pathophysiology, augmented by TNFα.
Analysis of mixed DNA‐bisnaphthalimide interactions involving groove association and intercalation with surface‐based and solution methodologies
Authors: González‐Bulnes Luis , Gallego José 
Published: June 2012

AbstractThe bisnaphthalimide cytotoxic agent elinafide exhibits a mixed DNA binding mode including groove‐association and intercalation. We have compared the interaction of elinafide and two bisnaphthalimide analogues with various natural and modified DNA sequences using solution NMR and UV‐melting methods and surface plasmon resonance (SPR) experiments at different pH conditions. The combined data obtained with these techniques established a high‐affinity binding mode comprising intercalation and strong electrostatic contacts with guanine bases in the major groove, and a weaker interaction with A·T pairs likely involving groove association. However, the SPR binding constants and the NMR and UV‐melting binding parameters responded differently to variations in DNA bases and ligand intercalating moieties. The rates and equilibrium constants determined by SPR clearly responded to changes in pH and DNA groove composition, but were rather insensitive to alterations in drug rings and DNA bases affecting the intercalation process. Conversely, the intermolecular stacking interactions detected by NMR and the ligand‐induced thermal stabilizations measured by UV depended on both sets of factors and were controlled by the sequence‐dependent properties of the DNA helices, indicating that these data were modulated by naphthalimide stacking in addition to groove association. A two‐step binding process where a groove‐bound state is required prior to intercalation is proposed as an explanation for these observations. These findings may be useful for studying other classes of DNA‐ and RNA‐binding drugs, which frequently combine groove‐binding and stacking moieties. © 2012 Wiley Periodicals, Inc.

Exploring Between the Extremes: Conversion‐Dependent Kinetics of Phosphite‐Modified Hydroformylation Catalysis
Authors: Kubis Christoph , Selent Detlef , Sawall Mathias , Ludwig Ralf , Neymeyr Klaus , Baumann Wolfgang , Franke Robert , Börner Armin 
Published: June 2012

AbstractThe kinetics of the hydroformylation of 3,3‐dimethyl‐1‐butene with a rhodium monophosphite catalyst has been studied in detail. Time‐dependent concentration profiles covering the entire olefin conversion range were derived from in situ high‐pressure FTIR spectroscopic data for both, pure organic components and catalytic intermediates. These profiles fit to Michaelis–Menten‐type kinetics with competitive and uncompetitive side reactions involved. The characteristics found for the influence of the hydrogen concentration verify that the pre‐equilibrium towards the catalyst substrate complex is not established. It has been proven experimentally that the hydrogenolysis of the intermediate acyl complex remains rate limiting even at high conversions when the rhodium hydride is the predominant resting state and the reaction is nearly of first order with respect to the olefin. Results from in situ FTIR and high‐pressure (HP) NMR spectroscopy and from DFT calculations support the coordination of only one phosphite ligand in the dominating intermediates and a preferred axial position of the phosphite in the electronically saturated, trigonal bipyramidal (tbp)‐structured acyl rhodium complex.
