Les lettres d’hommage de Linda Lê
Authors: Bacholle Michèle 
Published: May 2019

Si la lettre constitue une conversation entre absents, ceux-ci sont toutefois généralement vivants. Linda Lê, elle, écrit des lettres à des familiers morts (son père, décédé seul au Vietnam – Lettre morte, Paris, Christian Bourgois, 1999) ou à jamais confinés dans le non-être (son fils – À l’enfant que je n’aurai pas, Paris, NiL, 2011). En 1999 elle publie aussi Tu écriras sur le bonheur (Paris, Presses universitaires de France), trente-huit textes dédiés à des écrivains de renommée et d’origines diverses, sortes de « pères spirituels » ou littéraires et réitère son geste d’adresse en 2015, avec Par ailleurs (exils) (Paris, Christian Bourgois), lettres d’hommage à des écrivains par-delà le trépas. La tâche incombe alors au lecteur d’établir des correspondances entre eux et Linda Lê, entre les oeuvres achevées, passées à la postérité des uns et l’oeuvre en devenir, à la postérité encore incertaine de l’autre. Cet article identifie les continuités et discontinuités entre Tu écriras sur le bonheur et Par ailleurs (exils) et examine les cinq « figures tutélaires » qu’ils ont en commun, avant de relever quels sont les grands absents de Par ailleurs (exils) et quels écrivains y ont fait leur entrée. Alors que Tu écriras sur le bonheur était une compilation alphabétique, Par ailleurs (exils) est une suite d’hommages présentés pêle-mêle ; entre les deux se dessine le cheminement de l’oeuvre de Lê de la « littérature déplacée » vers une « littérature du dépaysement ». J’argue qu’il revient aux lecteurs et critiques, destinataires ultimes de ces lettres d’hommage, de les recevoir et d’assurer la postérité de leur auteure.
Habiter en ville : la maison urbaine dans le roman franco-canadien
Authors: Brun del Re Ariane 
Published: May 2019

En 2011, Jean Morency relevait la récurrence d’une figure spatiale particulière dans les littératures de l’Acadie, de l’Ontario français et de l’Ouest francophone : la maison incendiée, qu’il rattachait au temps, à la mémoire et à l’histoire. Depuis, les écrivains franco-canadiens ont délaissé cette figure au profit d’un autre type de logis, la maison urbaine. C’est notamment le cas de Daniel Poliquin, Simone Chaput et France Daigle. Les maisons atypiques de La Côte de Sable (1990, sous le titre Visions de Jude), La belle ordure (2010) ainsi que Petites difficultés d’existence (2002) et sa suite Pour sûr (2011) ont en commun d’être des espaces peu propices à l’intimité car ils brouillent les frontières entre l’intérieur et l’extérieur. Point de rencontre pour les personnages, ces maisons occupent une telle place qu’elles éclipsent les villes mises en scène. La maison urbaine semble ainsi être le moyen par lequel les écrivains franco-canadiens sont parvenus à s’approprier la ville pour l’habiter. La récurrence de cette nouvelle figure spatiale de même que le passage de la maison incendiée à la maison urbaine laissent entendre que les écrivains franco-canadiens puisent à un imaginaire commun. La littérature franco-canadienne pourrait ainsi compter non seulement sur des fondations institutionnelles, mais imaginaires.
Le mal de mère : solidarités féminines dans l’oeuvre de Marguerite Andersen et Hélène Harbec
Authors: Doyon-Gosselin Benoit , Greco Maria Cristina 
Published: May 2019

Les oeuvres de la Franco-Ontarienne Marguerite Andersen et de l’Acadienne Hélène Harbec, malgré leur importance quantitative et qualitative, ont été très peu étudiées par les chercheurs. Il faut dire que leurs textes de création s’inscrivent dans un contexte de forte décontextualisation et que leur point d’origine (l’Allemagne pour Andersen et le Québec pour Harbec) font d’elles des « étrangères » au sein de leur corpus national respectif, ceci expliquant peut-être cela. Pourtant, les oeuvres d’Andersen et d’Harbec témoignent de thématiques semblables et de rapprochement formels évidents. À la suite des travaux de Lori Saint-Martin et de Béatrice Didier, cet article vise à étudier le rapport à la mère et à son propre rôle de mère des personnages-écrivaines et à examiner la manière dont ces rapports servent de moteur à la création. Les oeuvres des deux auteures proposent une nouvelle solidarité entre femmes qui devient un modèle de vie. Nous voulons mettre en évidence la place problématique du rapport mère-enfant ainsi que les particularités d’une écriture de femmes qui se situent explicitement dans le sillage de la figure tutélaire de Virginia Woolf. Le corpus retenu est composé des oeuvres suivantes : De mémoire de femme ([1982] 2002), Le cahier des absences et de la décision ([1991] 2009), L’orgueilleuse (1998) et La mauvaise mère (2013).
Dans la machine lyrique de Pascal Dusapin
Authors: Gindt Antoine 
Published: May 2019

En sept opéras, Pascal Dusapin a exploré les nombreuses ramifications du
genre, s’inspirant d’auteurs contemporains comme de mythes ancestraux, traitant
différents formats – de l’opéra de chambre au grand opéra –, initiant et pratiquant
de nombreuses collaborations artistiques. Ses motivations et son cheminement très
personnels autour du texte, de la voix, de la musique, font ressortir la prééminence
de la partition qui doit libérer tous les autres paramètres engagés dans
l’assemblage complexe qu’est l’art lyrique.
Corps sonores : Aufgang et Outscape de Pascal Dusapin
Authors: Ouellet Pierre 
Published: May 2019

La poésie chante, la musique parle. Une communauté de voix sous-tend la langue parlée et le langage musical, qui prennent leur source dans l’écholalie où les mots et les notes s’assemblent selon des tournures d’ordre prosodique plutôt que des règles liées à la grammaire ou au solfège. Les intonations qui en résultent donnent lieu à ce que Heidegger appelle une Stimmung, soit une tonalité affective caractéristique d’une époque donnée, qui relève moins de la vie sociale que de la « vie chorale ou orchestrale », dont Rimbaud dit qu’elle est fondatrice de notre humanité. Aufgang et Outscape de Pascal Dusapin s’appuient sur cette communauté vocale, où l’on entend le « delà » (Auf) et le « dehors » (Out) propres à la posthistoire dans laquelle nous sommes entrés : le subtil entrelacs des instruments solistes et de l’orchestre y fait surgir de nouvelles tonalités, où l’on éprouve une autre forme de temporalité – musicale et poétique, certes, mais historique et politique aussi.

Published: May 2019

BackgroundPoa annuaL. is an example of a plant characterized by abundant, worldwide distribution from polar to equatorial regions. Due to its high plasticity and extraordinary expansiveness,P. annuais considered an invasive species capable of occupying and surviving in a wide range of habitats including pioneer zones, areas intensively transformed by human activities, remote subarctic meadows and even the Antarctic Peninsula region.MethodsIn the present study, we evaluated the utility of inter-primer binding site (iPBS) markers for assessing the genetic variation ofP. annuapopulations representing contrasting environments from the worldwide range of this species. The electrophoretic patterns of polymerase chain reaction products obtained for each individual were used to estimate the genetic diversity and differentiation between populations.ResultsiPBS genotyping revealed a pattern of genetic variation differentiating the six studiedP. annuapopulations characterized by their different climatic conditions. According to the analysis of molecular variance, the greatest genetic variation was recorded among populations, whereas 41.75% was observed between individuals within populations. The results of principal coordinates analysis (PCoA) and model-based clustering analysis showed a clear subdivision of analyzed populations. According to PCoA, populations from Siberia and the Kola Peninsula were the most different from each other and showed the lowest genetic variability. The application of STRUCTURE software confirmed the unique character of the population from the Kola Peninsula.DiscussionThe lowest variability of the Siberia population suggested that it was subjected to genetic drift. However, although demographic expansion was indicated by negative values of Fu’sFSstatistic and analysis of mismatch distribution, it was not followed by significant traces of a bottleneck or a founder effect. For the Antarctic population, the observed level of genetic variation was surprisingly high, despite the observed significant traces of bottleneck/founder effect following demographic expansion, and was similar to that observed in populations from Poland and the Balkans. For the Antarctic population, the multiple introduction events from different sources are considered to be responsible for such an observation. Moreover, the results of STRUCTURE and PCoA showed that theP. annuafrom Antarctica has the highest genetic similarity to populations from Europe.ConclusionsThe observed polymorphism should be considered as a consequence of the joint influence of external abiotic stress and the selection process. Environmental changes, due to their ability to induce transposon activation, lead to the acceleration of evolutionary processes through the production of genetic variability.
Polyphosphazene Polymer
Authors: Ogueri Kenneth S. , Allcock Harry R. , Laurencin Cato T. 
Published: May 2019

AbstractPolyphosphazenes are a unique class of inorganic–organic hybrid polymers with a backbone composed of alternating phosphorus and nitrogen atoms. The ease with which the precursor prepolymer poly(dichlorophosphazene) can be modified has resulted in a versatile polymer system. The labile nature of the P−Cl bonds has allowed the substitution of chlorine atoms with groups like alkoxy‐, aryloxy, alkyl ether, fluoroalkoxy, amino acid/peptide esters, drug molecules, transition metal groups, and many more. Careful selection of the side groups offers efficient control of material properties such as bioactivity, crystallinity, solubility, and surface characteristics. Hence, these properties have led to the use of this exceptional class of polymers in a broad range of applications such as biomaterials for regenerative engineering and drug delivery, elastomers, solid membranes for gas/liquid separation, optical materials, flame retardants, and electrolytes for energy storage cells. This article gives an overview of the synthetic routes of polyphosphazene polymers and their composition–structure–properties relationships and highlights their applications in various fields.

Published: May 2019

AbstractRational design of non‐noble metal catalysts with robust and durable electrocatalytic activity for oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) is extremely important for renewable energy conversion and storage, regenerative fuel cells, rechargeable metal–air batteries, water splitting etc. In this work, a unique hybrid material consisting of Fe3C and Co nanoparticles encapsulated in a nanoporous hierarchical structure of N‐doped carbon (Fe3C‐Co/NC) is fabricated for the first time via a facile template‐removal method. Such an ingenious structure shows great features: the marriage of 1D carbon nanotubes and 2D carbon nanosheets, abundant active sites resulting from various active species of Fe3C, Co, and NC, mesoporous carbon structure, and intimate integration among Fe3C, Co, and NC. As a multifunctional electrocatalyst, the Fe3C‐Co/NC hybrid exhibits excellent performance for ORR, OER, and HER, outperforming most of reported triple functional electrocatalysts. This study provides a new perspective to construct multifunctional catalysts with well‐designed structure and superior performance for clean energy conversion technologies.

Published: May 2019

AbstractExploration of high‐performance cathode materials for rechargeable aqueous Zn ion batteries (ZIBs) is highly desirable. The potential of molybdenum trioxide (MoO3) in other electrochemical energy storage devices has been revealed but held understudied in ZIBs. Herein, a demonstration of orthorhombic MoO3 as an ultrahigh‐capacity cathode material in ZIBs is presented. The energy storage mechanism of the MoO3 nanowires based on Zn2+ intercalation/deintercalation and its electrochemical instability mechanism are particularly investigated and elucidated. The severe capacity decay of the MoO3 nanowires during charging/discharging cycles arises from the dissolution and the structural collapse of MoO3 in aqueous electrolyte. To this end, an effective strategy to stabilize MoO3 nanowires by using a quasi‐solid‐state poly(vinyl alcohol)(PVA)/ZnCl2 gel electrolyte to replace the aqueous electrolyte is developed. The capacity retention of the assembled ZIBs after 400 charge/discharge cycles at 6.0 A g−1 is significantly boosted, from 27.1% (in aqueous electrolyte) to 70.4% (in gel electrolyte). More remarkably, the stabilized quasi‐solid‐state ZIBs achieve an attracting areal capacity of 2.65 mAh cm−2 and a gravimetric capacity of 241.3 mAh g−1 at 0.4 A g−1, outperforming most of recently reported ZIBs.

AbstractObjectivesThe objective of this study was to investigate the association between physical growth in preadult life with five outcomes at ages 64 to 76: weight, body mass index (BMI), estimated body fat percentage, hand grip strength, and mortality.MethodsSuper‐imposition by translation and rotation (SITAR) growth curves of 40 484 Guatemalan individuals aged 3 to 19 years were modeled for the parameters of size, timing and intensity (peak growth velocity, eg, cm/year) of height, weight, BMI, and grip strength. Associations between the SITAR parameters and old age outcomes were tested using linear and binary logistic regression for a follow‐up sample of high socioeconomic status (SES) Guatemalans, of whom 50 were aged 64 to 76 years at re‐measurement and 45 died prior to the year 2017.ResultsSITAR models explained 69% to 98% of the variance in each outcome, with height the most precise. Individuals in the follow‐up sample who had a higher BMI before the age of 20 years had higher estimated body fat (B = 1.4 CI −0.02‐2.8) and BMI (B = 1.2, CI 0.2‐2.2) at the ages of 64 to 76 years. Those who grew slower in height but faster in weight and BMI before the age of 20 years had higher BMI and body fat later in life.ConclusionsThese findings highlight the importance of a life course perspective on health and mortality risk. Childhood exposures leading to variation in preadult growth may be key to better understanding health and mortality risks in old age.

Published: May 2019

BackgroundThe purpose of this study was to use motion capture to collect body posture information during simulated endoscopic sinus surgery interventions performed by both specialists and residents in standing and sitting positions and to analyze that information with the validated Rapid Upper Limb Assessment (RULA) tool, which allows calculation of a risk index of musculoskeletal overload.MethodsBilateral endoscopic sinus surgery was performed in 5 cadaver heads by 2 residents, and 4 practicing rhinologists. Musculoskeletal symptoms were evaluated before and after the dissection. Full‐body postural data were collected with the help of Kinect and a .NET WPF (Windows Presentation Foundation) software application to record images of the surgical procedures, and then analyzed with the RULA tool to calculate a risk score indicative of the exposure of the individual surgeon to ergonomic risk factors associated with upper extremity musculoskeletal disorders.ResultsAll subjects reported physical discomfort after nasal endoscopic procedures. An overall similar RULA score was obtained by the residents and the practicing rhinologists. The RULA score was slightly lower for the sitting position than for the standing position, mostly due to a lower score in group B (neck, trunk, and leg); however, the RULA score for group A (arm and wrist analysis) was higher, denoting a higher risk for the upper back and arms.ConclusionSignificant musculoskeletal symptoms were reported after an endoscopic operation by both the resident and the practicing otolaryngologists. All surgeons obtained a high RULA score, meaning that urgent changes are required in the task.
Effects of coal ash on iron‐based oxygen carrier in chemical‐looping combustion using three different rank coals as fuel

Published: May 2019

AbstractThe combustion characteristics vary with coal rank changes, and coal ash has a significant effect on chemical looping combustion. In this work, combustion experiments of three coals and their acid‐washing samples were carried out in a bench‐scale fluidized bed reactor. The results showed that low‐rank coal had higher reactivity and shorter reduction time. On account of high volatility and low density, combustion efficiency of high volatile coal was lower than high‐rank coal resulting in lower CO2 concentration. CO2 concentration in combustion products of GY was up to 99.95%, but it was 91.2% for SF. The composition and content of coal ash had a great influence on the activity of the iron‐based oxygen carrier. Reactivity of the oxygen carrier was significantly increased after burning high Ca content coal, and ash shortened reduction time from 46 to 35 min. The coal with high Si content had negative effect on the reactivity of oxygen carriers. The coal ash mainly affected the oxygen carrier at the later stage of the reduction.

Published: May 2019

ABSTRACTGraphene oxide (GO) can improve the mechanical property of polymer matrix greatly. However, its poor dispersibility may considerably lower reinforcing efficiency. To address this problem, the environment‐friendly polyaspartic acid (PASP) was adopted to modify GO through two generally modified methods: hydrogen bond adsorption and chemical graft modification. Findings indicate that the covalent bond grafted PASP–GO exhibits better dispersibility than the product by noncovalent method (PASP/GO‐noncovalent). For chemically grafted PASP–GO, the nearly spherical polymer nanoparticles are formed on the GO nanosheets through self‐polymerization, and its size can be well manipulated by adjusting the dosage of PASP so as to yield PASP–GO‐1/4, PASP–GO‐1/2, and PASP–GO‐1/1 (mass ratio: mPASP/mGO = 1/4, 1/2, and 1/1); the corresponding diameters of these polymer aggregates are 56.4 ± 7.1, 90.1 ± 12.6, and 151.2 ± 16.1 nm. They are further utilized to reinforce polyimide matrix. Compared with the PASP–GO‐1/2 and PASP–GO‐1/1, the smaller PASP–GO‐1/4 has better strengthening effect, due to its high specific surface area and dense distribution. This desirable fabrication of GO‐based nanofillers provides a new avenue on the development of polymer matrix with comprehensive performances. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

Adaptive finite‐time neural network control for redundant parallel manipulators
Authors: Nguyen Van‐Truong , Su Shun‐Feng , Wang Ning , Sun Wei 
Published: May 2019

AbstractThis paper reports our study of an adaptive finite‐time neural network control scheme for redundant parallel manipulators. The proposed controller is based on fully tuned radial basis function neural networks (RBFNs), nonsingular fast terminal sliding mode control (NFTSMC), and nonlinearities in output feedback. RBFNs with a fully online update on the output weights and both the centers and variances of Gaussian functions are used to estimate system uncertainties and disturbances. The proposed approach possesses several advantages over other existing approaches like robustness, rapid response, nonsingularity, higher precision, finite‐time convergence, and better tracking control performance. The stability of the parallel manipulators is ensured by the Lyapunov theory. Finally, simulation results validate the effectiveness of the proposed methodology.
A weighted partial likelihood approach for zero‐truncated models
Authors: Hwang Wen‐Han , Heinze Dean , Stoklosa Jakub 
Published: May 2019

AbstractZero‐truncated data arises in various disciplines where counts are observed but the zero count category cannot be observed during sampling. Maximum likelihood estimation can be used to model these data; however, due to its nonstandard form it cannot be easily implemented using well‐known software packages, and additional programming is often required. Motivated by the Rao–Blackwell theorem, we develop a weighted partial likelihood approach to estimate model parameters for zero‐truncated binomial and Poisson data. The resulting estimating function is equivalent to a weighted score function for standard count data models, and allows for applying readily available software. We evaluate the efficiency for this new approach and show that it performs almost as well as maximum likelihood estimation. The weighted partial likelihood approach is then extended to regression modelling and variable selection. We examine the performance of the proposed methods through simulation and present two case studies using real data.

Published: May 2019

AbstractZingerone, 4‐(4‐hydroxy‐3‐methoxyphenyl)‐2‐butanone (Zg), a phenolic compound isolated from ginger is reported to have anti‐inflammatory and antidiabetic properties. However, its role in the promotion of osteogenesis is not known. In this study, we investigated the therapeutic effect of Zg on osteogenesis at the cellular and molecular levels. Zg treatment was nontoxic to mouse mesenchymal stem cells (mMSCs). At the cellular level, it enhanced osteoblast differentiation as evidenced by more calcium deposits. At the molecular level, Zg stimulated the expression of Runx2 (a bone transcription factor) and other marker genes of osteoblast differentiation in mMSCs. Recent studies indicated that microRNAs (miRNAs) regulate bone metabolism, and we identified that Zg treatment in mMSCs upregulated mir‐590, a positive regulator of Runx2 by targeting Smad7, an antagonist of TGF‐β1 signaling. Thus, the osteogenic potential of Zg would be beneficial for treating bone and bone‐related diseases.
