Le roman en perspective curieuse
Authors: Randall Marilyn 
Published: January 2013

« Trou de mémoire sera, lui aussi, une anamorphose, une série d’effets de perspective et de trompe-l’oeil. » Ce jugement sur le roman, émis par René Dionne en 1968, est suivi de près par un autre : « Trou de mémoire ne réussit qu’à dissimuler bien imparfaitement, malgré le fin drapé de sa prose et de sa composition en trompe-l’oeil, l’individu Hubert Aquin **. » Ces deux constats — que l’anamorphose gouverne la forme du roman et que la figure de l’auteur y est cachée — n’ont cessé de dominer la critique de Trou de mémoire depuis sa publication. Si l’anamorphose semble tournée résolument vers l’activité lectorale, posant un dilemme qui exige une multiplicité de perspectives, voire une schizophrénie perceptuelle, elle révèle en même temps la présence d’une intention auctoriale à l’origine du sens. L’anamorphose pose une énigme herméneutique située aux antipodes de la logique de « l’oeuvre ouverte » : qui ne déchiffre pas la « figure cachée » a raté sa lecture ; qui la déchiffre a perdu sa liberté interprétative ; l’auteur lui impose le sens final qu’il est seul à déterminer. L’anamorphose figure l’inscription à même l’oeuvre de la présence de l’auteur et de son intention. Que l’anamorphose comme clé de lecture de Trou de mémoire n’ait pas abouti à ouvrir tous les mystères de l’oeuvre ne fait que renforcer sa signification fondamentale, celle de révéler derrière les perspectives multiples du texte la présence singulière de son auteur.

Published: January 2013

AbstractLower limb entheseal changes are evaluated in order to reconstruct activity levels and more fully understand cultural and behavioral variation among the middle Holocene (ca. 9,000–3,000 years BP) foragers of Siberia's Cis‐Baikal region. The four cemetery samples examined span a period of diachronic change characterized by an 800‐ to 1,000‐year discontinuity in the use of formal cemeteries in the region. Two of the cemetery samples represent the early Neolithic Kitoi culture, dating from 8,000 to 7,000/6800 cal. BP; the other two represent the late Neolithic‐early Bronze Age Isakovo‐Serovo‐Glazkovo (ISG) cultural complex, dating from 6,000/5,800 to 4,000 cal. BP. Findings suggest a dynamic pattern of cultural variability in the Cis‐Baikal, with spatial distribution (i.e., site location within particular microregions) appearing to be just as important a factor as cultural/temporal affiliation in explaining intersample differences in entheseal morphology. In addition, intrasample comparisons reveal increasing sexual disparity with advancing age at death, emphasizing the influence of sex‐related activities on lower limb entheseal changes. Finally, results from the separate fibrous and fibrocartilaginous datasets appear to be largely congruous, implying that activity patterns in the Cis‐Baikal may have similar effects on the morphology of both types of entheses.

ObjectiveAdvancing the understanding and management of thromboembolic stroke requires simple and robust new methods that would be useful for the in vivo assessment of thrombus burden/distribution and for characterizing its evolution in a prompt and quantitative manner.MethodsAnimals (n=127) with experimental models of thrombosis were imaged with microcomputed tomography 5 minutes (and/or ∼3 weeks) after intravenous injection of glycol chitosan (GC) gold nanoparticles (AuNPs).ResultsNanoparticles accumulated in the thrombus, allowing computed tomography visualization of both the presence and extent of primary and recurrent thrombi in mouse carotid arteries without a single failure of detection. Nanoparticle thrombus imaging was also effective in monitoring the therapeutic efficacy of thrombolysis (n=118 tissue plasminogen activator [tPA] therapies). Thrombus evolution (either spontaneous or post‐tPA) could be mapped at high resolution in both space and time. Due to a long circulating half‐life, GC‐AuNPs remain available for entrapment into fibrin matrix for an extended period of time (up to 3 weeks), allowing repetition or ongoing monitoring of thrombogenesis and thrombolysis.InterpretationThis is the first report on a hyperacute direct thrombus imaging technique using thrombus‐seeking AuNPs and computed tomography. When translated into stroke practice, the thrombus imaging may allow us to advance to personalized thrombolytic therapy by demonstrating thrombus burden, distribution, and character in a prompt and quantitative manner. Further study into this area is indicated. ANN NEUROL 2013;73:617–625

Published: January 2013

ObjectivesWe report the Melody valve implanted and/or expanded to 24‐mm diameter.BackgroundThe Medtronic Melody valve has been implanted up to 22 mm in the pulmonary position for over a decade.MethodsA retrospective chart review was performed on 82 patients who underwent Melody valve implant. Technical implant method, pre‐ and postimplant echocardiographic findings, and initial follow‐up were reviewed.ResultsBetween 04/2008 and 12/2011, 13 Melody valves were successfully implanted in 11 patients, median age 35 years (range 16–61 years), in the pulmonary (bioprosthetic valve, right ventricle to pulmonary artery conduit, native valve) position (n = 9), tricuspid position (bioprosthetic valve n = 3), and aortic position (bioprosthetic valve n = 1). Ten valves were delivered on a 24‐mm balloon in balloon catheter and three were implanted using a 22‐mm Ensemble balloon delivery system, followed by postdilation using a 24‐mm × 2‐cm Atlas balloon catheter. Postimplant, the median peak systolic gradient across the pulmonary valve was 7 mm Hg and median gradient across the tricuspid valve was 3 mm Hg. There was no change in gradient across the Melody valve in the aortic position where valve prosthesis–patient mismatch was present. Postimplant intracardiac echocardiography demonstrated none or mild valve regurgitation. No more than mild regurgitation was noted at a median follow‐up of 9.5 months.ConclusionsThe Melody valve can be implanted at 24 mm in the stenotic/regurgitant bioprosthetic pulmonary, tricuspid, and aortic valve, dysfunctional right ventricle to pulmonary artery conduit, and the native right ventricular outflow tract, whereas the valve remains competent with only mild regurgitation. © 2013 Wiley Periodicals, Inc.
2‐(2′‐Pyridyl)‐4,6‐diphenylphosphinine versus 2‐(2′‐Pyridyl)‐4,6‐diphenylpyridine: Synthesis, Characterization, and Reactivity of Cationic RhIII and IrIII Complexes Based on Aromatic Phosphorus Heterocycles

Published: January 2013

AbstractThe bidentate P,N hybrid ligand 1 allows access for the first time to novel cationic phosphinine‐based RhIII and IrIII complexes, broadening significantly the scope of low‐coordinate aromatic phosphorus heterocycles for potential applications. The coordination chemistry of 1 towards RhIII and IrIII was investigated and compared with the analogous 2,2′‐bipyridine derivative, 2‐(2′‐pyridyl)‐4,6‐diphenylpyridine (2), which showed significant differences. The molecular structures of [RhCl(Cp*)(1)]Cl and [IrCl(Cp*)(1)]Cl (Cp*=pentamethylcyclopentadienyl) were determined by means of X‐ray diffraction and confirm the mononuclear nature of the λ3‐phosphinine–RhIII and IrIII complexes. In contrast, a different reactivity and coordination behavior was found for the nitrogen analogue 2, especially towards RhIII as a bimetallic ion pair [RhCl(Cp*)(2)]+[RhCl3(Cp*)]− is formed rather than a mononuclear coordination compound. [RhCl(Cp*)(1)]Cl and [IrCl(Cp*)(1)]Cl react with water regio‐ and diastereoselectively at the external PC double bond, leading exclusively to the anti‐addition products [MCl(Cp*)(1H⋅OH)]Cl as confirmed by X‐ray crystal‐structure determination.
Three Polymorphic CdII Coordination Polymers Obtained from the Solution and Mechanochemical Reactions of 3‐Cyanopentane‐2,4‐dione with CdII Acetate

AbstractWe previously reported that monomeric and polymeric metal complexes are obtained from solution and mechanochemical reactions of 3‐cyano‐pentane‐2,4‐dione (CNacacH) with 3d metal acetates (M=MnII, FeII, CoII, NiII, CuII, and ZnII). A common feature found in all complexes was that their structural base is trans‐[M(CNacac)2]. Here, we report that the reactions of CNacacH with CdII acetate in the solution and solid states afford different coordination polymers composed of trans‐[Cd(CNacac)2] and cis‐[Cd(CNacac)2] units, respectively. From a methanol solution containing CNacacH (L) and Cd(OAc)2⋅2 H2O (M), a coordination polymer (Cd‐1) in which trans‐[Cd(CNacac)2] units are three‐dimensionally linked was obtained. In contrast, two different coordination polymers, Cd‐2 and Cd‐3, were obtained from mechanochemical reactions of CNacacH with Cd(OAc)2⋅2 H2O at M/L ratios of 1:1 and 1:2, respectively. In Cd‐2, cis‐[Cd(CNacac)2] units are two‐dimensionally linked, whereas the units are linked three‐dimensionally in Cd‐3. Furthermore, Cd‐1 and Cd‐2 converted to Cd‐3 by applying an annealing treatment and grinding with a small amount of liquid, respectively, in spite of the polymeric structures. These phenomena, 1) different structures are formed from solution and mechanochemical reactions, 2) two polymorphs are formed depending on the M/L ratio, and 3) structural transformation of resulting polymeric structures, indicate the usability of mechanochemical method in the syntheses of coordination polymers as well as the peculiar structural flexibility of cadmium‐CNacac polymers.

AbstractRemarkably enhanced stability of the self‐assembled hydrogen‐bonded heterocapsule 1⋅2 by the encapsulation of 1,4‐bis(1‐propynyl)benzene 3 a was found with Ka=1.14×109 M−1 in CDCl3 and Ka2=1.59×108 M−2 in CD3OD/CDCl3 (10 % v/v) at 298 K. The formation of 3 a@(1⋅2) was enthalpically driven (ΔH°<0 and ΔS°<0) and there was a unique inflection point in the correlation between ΔH° versus ΔS° as a function of polar solvent content. The ab initio calculations revealed that favorable guest–capsule dispersion and electrostatic interactions between the acetylenic parts (triple bonds) of 3 a and the aromatic inner space of 1⋅2, as well as less structural deformation of 1⋅2 upon encapsulation of 3 a, play important roles in the remarkable stability of 3 a@(1⋅2).

Published: January 2013

AbstractIn a spray agglomeration process the particle wetting influences the agglomerate growth and particle dynamics in the granulator. The mass of binder liquid that is deposited on single particles affects the amount of energy dissipation during particle contacts. For the agglomeration of colliding particles the whole impact energy has to be dissipated due to viscous and capillary adhesion forces in the liquid film and plastic deformation of the material. Therefore, a detailed knowledge of the particle wetting is necessary to model the agglomeration process. This contribution uses a coupled DEM‐CFD approach to describe the spray zone of a two‐fluid nozzle in a fluidized bed agglomerator. Droplets modeled as discrete elements showed the formation of a spray zone with a conical shape. Simulations of the spray zone and the wetting of single particles are in good agreement with experimental results.

AbstractKohlendioxid kann als C1‐Baustein für chemische Reaktionen eingesetzt werden. Um die Reaktivität des Kohlendioxids zu erhöhen, wird dieses zuerst durch die reverse Wassergas‐Shift‐Reaktion (rWGS) mit Wasserstoff in einem adsorptiven Reaktor zu Kohlenmonoxid reduziert. Es wurden simulative und experimentelle Studien durchgeführt, um die Leistung eines adsorptiven rWGS‐Reaktors zu bewerten. Es zeigt sich, dass mithilfe des adsorptiven Reaktorkonzepts der Gleichgewichtsumsatz bei 225 – 250 °C deutlich erhöht werden kann.
Statistical inference for multivariate partially linear regression models
Authors: You Jinhong , Zhou Yong , Chen Gemai 
Published: January 2013

AbstractIn this paper we study a class of multivariate partially linear regression models. Various estimators for the parametric component and the nonparametric component are constructed and their asymptotic normality established. In particular, we propose an estimator of the contemporaneous correlation among the multiple responses and develop a test for detecting the existence of such contemporaneous correlation without using any nonparametric estimation. The performance of the proposed estimators and test is evaluated through some simulation studies and an analysis of a real data set is used to illustrate the developed methodology.The Canadian Journal of Statistics41: 1–22; 2013 © 2013 Statistical Society of Canada
Magnesium Ammonium Phosphate Production from Wastewater through Box–Behnken Design and Its Effect on Nutrient Element Uptake in Plants
Authors: Uysal Ayla , Kuru Begüm 
Published: January 2013

AbstractThis study examined ${\rm NH}_{{\rm 4}}^{{\rm + }} $, ${\rm PO}_{{\rm 4}}^{{\rm 3}- } $ recovery and the concentration of residual ions from anaerobic effluent of the potato processing industry through magnesium ammonium phosphate (MAP) precipitation using a Box–Behnken design. The regression model was statistically significant in terms of ${\rm NH}_{{\rm 4}}^{{\rm + }} $ and ${\rm PO}_{{\rm 4}}^{{\rm 3}- } $ removal efficiency and residual ion concentrations. Optimum ${\rm NH}_{{\rm 4}}^{{\rm + }} $ and ${\rm PO}_{{\rm 4}}^{{\rm 3}- } $ removal was obtained at pH 9.50 and at Mg2+/${\rm NH}_{{\rm 4}}^{{\rm + }} $/${\rm PO}_{{\rm 4}}^{{\rm 3}- } $ molar ratio of 1.8:1:1.8. Under these conditions, Mg, Ca, K, Fe, and Cl concentrations required for plant growth significantly decreased with MAP precipitation, which was supported by EDX analysis of dry MAP precipitate. The fertilizer effect of MAP on the growth of corn and tomato plants was compared with chemical fertilizers through pot trials. Nutrient element uptake levels of plants were examined in different fertilizer sources. While Mg, Fe, Cu, Mn, and Zn nutrient element uptake levels were sufficient in MAP pots, Ca uptake exceeded sufficient level. Average levels of N, P, K, Mg, Cu, and Mn of corn plant were higher in MAP than other pots. The average N, P, and Mg levels of tomato plant in MAP pots were higher than other pots. N/K ratio, which is important in tomato plants, was better optimized in MAP pots. Only Ni, Cr, and Pb heavy metals were found in plants.

Published: January 2013

AbstractBACKGROUND:Studies of the performance of the automated FocalPoint Guided Screening (FPGS) imaging system in gynecologic cytology screening relative to manual screening have yielded conflicting results. In view of this uncertainty, a validation study of the FPGS was conducted before its potential adoption in 2 large laboratories in Ontario.METHODS:After an intense period of laboratory training, a cohort of 10,233 current and seeded abnormal slides were classified initially by FPGS. Manual screening and reclassification blinded to the FPGS results were then performed. Any adequacy and/or cytodiagnostic discrepancy between the 2 screening methods subsequently was resolved through a consensus process (truth). The performance of each method's adequacy and cytodiagnosis vis‐a‐vis the truth was established. The sensitivity and specificity of each method at 4 cytodiagnostic thresholds (atypical squamous cells of undetermined significance or worse [ASC‐US+], low‐grade squamous intraepithelial lesion or worse [LSIL+], high‐grade squamous intraepithelial lesion or worse [HSIL+], and carcinoma) were compared. The false‐negative rate for each cytodiagnosis was determined.RESULTS:The performance of FPGS in detecting carcinoma, HSIL+, and LSIL+ was no different from the performance of manual screening, but the false‐negative rates for LSIL and ASC‐US were higher with FPGS than with manual screening.CONCLUSIONS:The results from this validation study in the authors' laboratory environment provided no evidence that FPGS has diagnostic performance that differs from manual screening in detecting LSIL+, HSIL+, or carcinoma.

Resource provisioning based on preempting virtual machines in distributed systems
Authors: Salehi Mohsen Amini , Javadi Bahman , Buyya Rajkumar 
Published: January 2013

SUMMARYResource provisioning is one of the main challenges in large‐scale distributed systems such as federated Grids. Recently, many resource management systems in these environments have started to use the lease abstraction and virtual machines (VMs) for resource provisioning. In the large‐scale distributed systems, resource providers serve requests from external users along with their own local users. The problem arises when there is not sufficient resources for local users, who have higher priority than external ones, and need resources urgently. This problem could be solved by preempting VM‐based leases from external users and allocating them to the local ones. However, preempting VM‐based leases entails side effects in terms of overhead time as well as increasing makespan of external requests. In this paper, we model the overhead of preempting VMs. Then, to reduce the impact of these side effects, we propose and compare several policies that determine the proper set of lease(s) for preemption. We evaluate the proposed policies through simulation as well as real experimentation in the context of InterGrid under different working conditions. Evaluation results demonstrate that the proposed preemption policies serve up to 72% more local requests without increasing the rejection ratio of external requests.

Published: January 2013

SUMMARYIntercell interference coordination in Third Generation Partnership Project long‐term evolution‐advanced system has received much attention both from the academia and the standardization communities. Moreover, the network architecture of long‐term evolution‐advanced system is modified to take into account coordinated transmission. In this article, we study the dynamic resource allocation problem and potential game theory and propose a multicell adaptive distributed resource allocation algorithm based on potential game. The allocation process is divided into two steps; subchannel is allocated first, and then, transmitted power is optimized dynamically according to a novel pricing factor. Besides, existence and uniqueness of Nash equilibrium of the proposed game model are assured. As a result, intercell interference is well coordinated. Simulation results show that transmitted power is saved efficiently and system fairness is improved to a large extent, accompanied with good performance gain of total and cell‐edge throughputs.

The 1,3‐Diamino‐1,2,3‐triazolium Cation: A Highly Energetic Moiety
Authors: Klapötke Thomas M. , Piercey Davin G. , Stierstorfer Jörg 
Published: January 2013

AbstractThe 1,3‐diamino‐1,2,3‐triazolium cation has been prepared by the amination of 1‐amino‐1,2,3‐triazole with O‐tosylhydroxylamine. The cation shows a very positive enthalpy of formation and is therefore highly suitable as the fuel component in new energetic materials. The cation was then paired with the energetic anions nitrate, nitrotetrazolate‐2‐oxide, 5,5′‐bis(1‐oxidotetrazolate), 5,5′‐azobis(1‐oxidotetrazolate), and nitriminotetrazolate and characterized. All the prepared compounds are high‐performance energetic materials, and when performances were compared with the corresponding triaminoguanidinium salt, those of 1,3‐diamino‐1,2,3‐triazolium were generally superior, as calculated by the EXPLO5 computer code. The heats of formation were calculated at the CBS‐4M level of theory. The impact, friction, and electrical spark sensitivities of the 1,3‐diamino‐1,2,3‐triazolium salts were measured and found to be easily initiated energetic materials.
Early‐Lanthanide Complexes with All‐Inorganic Macrocyclic Polyoxovanadate Ligands
Authors: Nishio Masaki , Inami Shinnosuke , Hayashi Yoshihito 
Published: January 2013

AbstractThree discrete early‐lanthanide complexes with cyclic polyoxovanadate ligands, [LaV10O30]7– (1), [CeV9O27]6– (2), and [PrV9O27]6– (3), were synthesized by reaction of [VO3]– with early‐lanthanide(III) salts. Complexes 1–3 were composed of a LnIII center in square‐antiprism coordination mode with coordinated all‐inorganic ligands [VnO3n]n– (n = 9 or 10), which were constructed from a cyclic linkage of nine or ten VO4 tetrahedra through vertex sharing. Structural investigation of lanthanum complex 1 revealed a ten‐membered ring of VO4 units in which eight VO4 units were coordinated to the lanthanum atom through their oxido groups and two VO4 units at opposite sides of the ring were not coordinated. Cerium complex 2 and praseodymium complex 3 both contained a nine‐membered cyclic ligand with eight VO4 coordinated units and one uncoordinated unit among nine tetrahedral VO4 units. 51V NMR spectra of 1–3 in acetonitrile showed reversible temperature dependences at –40–70 °C, thus indicating fluxional behavior of the macrocyclic polyoxovanadate ligands in solution. Exchange of the coordinated and uncoordinated VO4 sites in the ring was responsible for these reversible processes.
