Trois littératures francophones au Canada 1972-1992
Authors: Dionne René 
Published: September 2017

René Dionne, qui embrasse dans un même parallèle « trois littératures francophones du Canada », évoque l’émergence de ces entités régionales du Canada français et leur développement récent, entre 1972 et 1992. Après leur affranchissement du Québec, qui avait confisqué et, à rebours, rebaptisé « québécois » tout l’héritage qui forma jadis la feue « littérature nationale » ou « canadienne », puis naguère « canadienne-française », ces trois littératures ont vécu des stades de contestation puis de récupération de leur patrimoine écrit. Le réveil des identités régionales, excité par l’attitude souvent méprisante du Québec, a provoqué la prise de parole des minorités qui, aidées de leurs établissements séculaires et des gouvernements, ont institué de plus en plus solidement et complètement les littératures acadienne, franco-ontarienne et francophone de l’Ouest.

AbstractSince March 2014, there is a continuous measurement of secondary cosmic rays by the detector system SEVAN (Space Environmental Viewing and Analysis Network) at Lomnický štít, altitude 2,634 m above sea level. Starting from June 2016, the count rates (1 s resolution) obtained from the three SEVAN detectors and from their coincidences are available, along with selected meteorological characteristics. Since 30 May 2016 the electric field measurements have been installed at the same site. Several events with clear increase of the count rate in the upper detector of SEVAN were observed during the thunderstorms until 17 September 2016. Examples of these measurements are presented and discussed. Barometric pressure correction and elimination of low‐frequency variability from the signal allow to extract 2 min averaged increases from the data. It is shown that the 2 min averaged increases of count rates measured by SEVAN correspond with periods of high electric field (with higher probability during negative polarity) rather than with the individual discharges (lightning).

ObjectiveThis retrospective analysis examined how sustained remission impacted risk of serious infections in patients with rheumatoid arthritis (RA) enrolled in a clinical registry.MethodsInclusion criteria included RA diagnosis, age ≥18 years, and ≥2 Clinical Disease Activity Index (CDAI) scores followed by a followup visit. Index date was the second of 2 visits in which a patient had sustained remission (CDAI ≤2.8), low disease activity (LDA; 2.8 < CDAI ≤10), or moderate‐to‐high disease activity (MHDA; CDAI >10). Followup extended from the index date until first serious infection (requiring intravenous antibiotics or hospitalization) or last followup visit. The crude incidence rate (IR) per 100 patient‐years for serious infections was calculated for the sustained remission, LDA, and MHDA groups. The multivariable‐adjusted incidence rate ratio (IRR) (adjusted for age, sex, and prednisone dose) compared serious infection rates across disease activity groups.ResultsMost patients were female (>70%); mean age was approximately 60 years. The crude IR (95% confidence interval [95% CI]) per 100 patient‐years for serious infections was 1.03 (0.85–1.26) in the sustained remission group (n = 3,355), 1.92 (1.68–2.19) in the sustained LDA group (n = 3,912), and 2.51 (2.23–2.82) in the sustained MHDA group (n = 5,062). Compared to sustained remission, the serious infection rate was higher in sustained LDA (adjusted IRR 1.69 [95% CI 1.32–2.15]). Compared to sustained LDA, the serious infection rate was higher in sustained MHDA (adjusted IRR 1.30 [95% CI 1.09–1.56]).ConclusionIn this study, lower RA disease activity was associated with lower serious infection rates. This finding may motivate patients and health care providers to strive for remission rather than only LDA.

AbstractMonolithic porous bulk materials have many promising applications ranging from energy storage and catalysis to high energy density physics. High resolution additive manufacturing techniques, such as direct laser writing via two photon polymerization (DLW‐TPP), now enable the fabrication of highly porous microlattices with deterministic morphology control. In this work, DLW‐TPP is used to print millimeter‐sized foam reservoirs (down to 0.06 g cm−3) with tailored density‐gradient profiles, where density is varied by over an order of magnitude (for instance from 0.6 to 0.06 g cm−3) along a length of <100 µm. Taking full advantage of this technology, however, is a multiscale materials design problem that requires detailed understanding of how the different length scales, from the molecular level to the macroscopic dimensions, affect each other. The design of these 3D‐printed foams is based on the brickwork arrangement of 100 × 100 × 16 µm3 log‐pile blocks constructed from sub‐micrometer scale features. A block‐to‐block interdigitated stitching strategy is introduced for obtaining high density uniformity at all length scales. Finally, these materials are used to shape plasma‐piston drives during ramp‐compression of targets under high energy density conditions created at the OMEGA Laser Facility.

Published: September 2017

AbstractConventional design wisdom prevents both bulk and interfacial toughness to be presented in the same hydrogel, because the bulk properties of hydrogels are usually different from the interfacial properties of the same hydrogels on solid surfaces. Here, a fully‐physically‐linked agar (the first network)/poly(N‐hydroxyethyl acrylamide) (pHEAA, the second network), where both networks are physically crosslinked via hydrogen bonds, is designed and synthesized. Bulk agar/pHEAA hydrogels exhibit high mechanical properties (2.6 MPa tensile stress, 8.0 tensile strain, 8000 J m−2 tearing energy, 1.62 MJ m−3 energy dissipation), high self‐recovery without any external stimuli (62%/30% toughness/stiffness recovery), and self‐healing property. More impressively, without any surface modification, agar/pHEAA hydrogels can be easily and physically anchored onto different nonporous solid substrates of glass, titanium, aluminum, and ceramics to produce superadhesive hydrogel–solid interfaces (i.e., high interfacial toughness of 2000–7000 J m−2). Comparison of as‐prepared and swollen gels in water and hydrogen‐bond‐breaking solvents reveals that strong bulk toughness provides a structural basis for strong interfacial toughness, and both high toughness mainly stem from cooperative hydrogen bonds between and within two networks and between two networks and solid substrates. This work demonstrates a new gel system to achieve superhigh bulk and interfacial toughness on nonporous solid surfaces.

Published: September 2017

AbstractBroadband photodetectors based on TiO2 nanotubes (NTs) array have significant prospects in many fields such as environmental monitoring. Herein, a simple spin‐coating process is successfully adopted to incorporate MAPbI3 quantum dots (QDs) onto the surface of TiO2 NTs to form a heterostructure, extending the response range of TiO2 NT from ultraviolet to visible. Compared with pure TiO2 NTs, the heterostructure demonstrates an improvement of responsivity in visible range by three orders of magnitude, and maintains its response performance in the UV range simultaneously. The TiO2 NTs based heterostructure photodetectors demonstrate a relative fast and stable response in the 300–800 nm range and even have a reponsivity of 0.2 A W−1 at 700 nm. The photoelectric performance of the hybrid photodetector based on TiO2 NTs maintains well when exposed to moist air for 72 h or heated from room temperature to 100 °C. Moreover, such a TiO2 NTs/MAPbI3 QDs heterostructure device demonstrates excellent flexibility and high transparency (85%) in the 400–800 nm range, their photodetecting performance is well retained after 200 cycles of repeated bending at 90°. The present strategy that combines facile electrospinning and solution‐processed QDs may open a new avenue for wide range response and flexible devices construction.

Published: September 2017

AbstractInkjet printing (IJP) technology, adapted from home and office printing, has proven to be an essential research tool and industrial manufacturing technique in a wide range of printed electronic technologies, including optoelectronics. Its primary advantage over other deposition methods is the low‐cost and maskless on‐demand patterning, which offers unmatched freedom‐of‐design. Additional benefits include the efficient use of materials, contactless high‐resolution deposition, and scalability, enabling rapid translation of learning from small‐scale, laboratory‐based research into large‐scale industrial roll‐to‐roll manufacturing. In the development of organic solar cells (OSCs), IJP has enabled the printing of many of the multiple functional layers which comprise the complete cell as part of an additive printing scheme. Although IJP is only recently employed in perovskite solar cell (PeSC) fabrication, it is already showing great promise and is anticipated to find broader application with this class of materials. As OSCs and PeSCs share many common functional materials and device architectures, this review presents a progress report on the IJP of OSCs and PeSCs in order to facilitate knowledge transfer between the two technologies, with critical analyses of the challenges and opportunities also presented.

Published: September 2017

AbstractThe development of omnidirectionally stretchable pressure sensors with high performance without stretching‐induced interference has been hampered by many challenges. Herein, an omnidirectionally stretchable piezoresistive pressure‐sensing device is demonstrated by combining an omniaxially stretchable substrate with a 3D micropattern array and solution‐printing of electrode and piezoresistive materials. A unique substrate structural design and materials mean that devices that are highly sensitive are rendered, with a stable out‐of‐plane pressure response to both static (sensitivity of 0.5 kPa−1 and limit of detection of 28 Pa) and dynamic pressures and the minimized in‐plane stretching responsiveness (a small strain gauge factor of 0.17), achieved through efficient strain absorption of the electrode and sensing materials. The device can detect human‐body tremors, as well as measure the relative elastic properties of human skin. The omnidirectionally stretchable pressure sensor with a high pressure sensitivity and minimal stretch‐responsiveness yields great potential to skin‐attachable wearable electronics, human–machine interfaces, and soft robotics applications.

Afterward, their applications are discussed as electrode materials or catalysts for lithium‐ion batteries, hybrid supercapacitors, water‐splitting devices, and fuel cells. Lastly, the research challenges and possible development directions of complex nanostructures derived from MOF‐based‐templates for electrochemical energy storage and conversion applications are outlined.

Published: September 2017

AbstractA highly efficient and straightforward approach for the synthesis of spiroepoxy chroman‐4‐one derivatives was developed using a visible light‐enabled tandem radical strategy. The reaction is initiated by the formation of an acyl radical that undergoes intramolecular radical cyclization and epoxidation. The optimal result was obtained with 1 mol% of Ru(bpy)3Cl2⋅6H2O, TBHP, and K2CO3 in i‐PrOAc at room temperature with irradiation from a blue LED. This unprecedented tandem approach utilizes a broad range of substrates, and provides a convenient and powerful synthetic tool for accessing the synthetically useful spiroepoxy chroman‐4‐ones and their nitrogen‐containing derivatives.magnified image

Published: September 2017

AbstractFollowing the modular template synthesis using isonitriles, new unsymmetrically substituted five‐membered saturated N‐heterocyclic carbene (NHC) and N‐heterocyclic oxo‐carbene (NHOC) gold(I) complexes were prepared. With these species and already reported complexes, a detailed study concerning the catalytic activities of the complex classes available by the isonitrile route was conducted. The catalytic properties of twelve different types of NHOCs, saturated and unsaturated NHC gold(I) pre‐catalysts with different substituents, as well as one representative of a six‐membered NHC and one N‐acyclic carbene (NAC) gold(I) complex were analyzed by utilizing the phenol synthesis as a test reaction. For this reaction, the saturated NHC gold(I) complexes achieved higher conversions than the corresponding unsaturated NHCs and the NHOC systems. While unsaturated NHC complexes show higher catalytic activity during the initial phase of the conversion, due to a higher stability, higher turnover numbers (TONs) were obtained for the corresponding saturated systems. A cyclopentadecyl substituent at nitrogen turned out to be the privileged substituent for all of the unsymmetrical complexes. Furthermore, we detected that light exclusion can significantly increase the catalytic activity of NHC gold(I) complexes for phenol synthesis.magnified image

AbstractInherited platelet disorders (IPD) are a heterogeneous group of rare disorders that affect platelet number and function and often predispose to other significant medical complications. In spite of the identification of over 50 IPD disease‐associated genes, a molecular diagnosis is only identified in a minority (10%) of affected patients without a clinically suspected etiology. We studied a cohort of 21 pediatric patients with suspected IPDs by exome sequencing (ES) to: (1) examine the performance of the exome test for IPD genes, (2) determine if this exome‐wide diagnostic test provided a higher diagnostic yield than has been previously reported, (3) to evaluate the frequency of variants of uncertain significance identified, and (4) to identify candidate variants for functional evaluation in patients with an uncertain or negative diagnosis. We established a high priority gene list of 53 genes, evaluated exome capture kit performance, and determined the coverage for these genes and disease‐related variants. We identified likely disease causing variants in 5 of the 21 probands (23.8%) and variants of uncertain significance in 52% of patients studied. In conclusion, ES has the potential to molecularly diagnose causes of IPD, and to identify candidate genes for functional evaluation. Robust exome sequencing also requires that coverage of genes known to be associated with clinical findings of interest need to be carefully examined and supplemented if necessary. Clinicians who undertake ES should understand the limitations of the test and the full significance of results that may be returned.

AbstractAchievement of a normal FLC ratio (FLCr) following treatment indicates hematologic response and suggests better outcomes in light chain amyloidosis (AL). We examined if elevated involved free light chain (hiFLC) impacts outcomes in patients achieving normal FLCr. We retrospectively analyzed 345 AL patients who were diagnosed within a 10‐year period (2006‐2015) and had 2 consecutive normal FLCr values after 1st line treatment. Among these, patients with hiFLC at 1st reading of normal FLCr (hiFLC1; n = 166; 48.1%) were compared to those who did not (n = 179; 51.9%). Patients with AL who have hiFLC1 after initial therapy had higher rates of multi‐organ involvement (63.3 vs 46.4%; P = .002) and patients in advanced Mayo stage (42.9 vs 32.2%; P = .04) at diagnosis. The median progression free survival [PFS; 38.2 (95%CI; 26.4, 55.4) vs 67.1 (95%CI; 55.8, 88) months; P = .0002] and overall survival [OS; 94.4 (95%CI; 78, 107.1) vs not reached (NR, 95%CI; 116.1, NR) months; P < .0001] were lower in those who had hiFLC1. A more stringent comparison for patients with 2 consecutive hiFLC (hIFLC2; n = 111; 32.2%) versus not (n = 2234; 67.8%) showed consistent results [PFS; 27.1 (95%CI; 23, 53.8) vs 63.3 (95%CI; 55.4, 77) months; P < .0001 and OS; 78 (95% CI; 54.6, 98.8) vs NR (95%CI; NR, NR); P < .0001]. This poor prognostic impact of hiFLC on survival was independent of serum creatinine, Mayo stage, negative immunofixation status and inclusion of transplant in initial therapy on multivariate analysis. Hence, persistent elevation of iFLC predicts poor prognosis even among patients achieving normal ratio after initial therapy in AL.

Published: September 2017

AbstractWe have described the chemoselective behavior of iodine in the oxidative esterification and electrophilic iodocyclization of hydroxyalkynyl aldehydes that contain a primary alcohol moiety. In the presence of an alcohol, which serves as the nucleophile and solvent, the reaction of the hydroxyalkynyl aldehydes and I2 proceeds through a hemiacetal species to give alkyl 4‐(3‐hydroxyalkynyl)benzoate esters. In CH2Cl2, these substrates undergo an electrophilic iodocyclization through a cyclic iodonium ion to provide a synthetic route for the formation of the bioactive dihydrofuran/pyran ring system.

AbstractCarbon monoxide (CO) outcompetes oxygen when binding to the iron center of hemeproteins, leading to a reduction in blood oxygen level and acute poisoning. Harvesting the strong specific interaction between CO and the iron porphyrin provides a highly selective and customizable sensor. We report the development of chemiresistive sensors with voltage‐activated sensitivity for the detection of CO comprising iron porphyrin and functionalized single‐walled carbon nanotubes (F‐SWCNTs). Modulation of the gate voltage offers a predicted extra dimension for sensing. Specifically, the sensors show a significant increase in sensitivity toward CO when negative gate voltage is applied. The dosimetric sensors are selective to ppm levels of CO and functional in air. UV/Vis spectroscopy, differential pulse voltammetry, and density functional theory reveal that the in situ reduction of FeIII to FeII enhances the interaction between the F‐SWCNTs and CO. Our results illustrate a new mode of sensors wherein redox active recognition units are voltage‐activated to give enhanced and highly specific responses.

Published: September 2017

AbstractThis investigation demonstrates that a series of biphenylenes can be easily prepared from their corresponding halobiphenyls by the cyclization of in situ generated 2′,3′‐didehydro‐2‐lithiobiphenyls at low temperature. Two remarkable advantages of this synthetic method include 1) the lack of any need for transition‐metal catalysts or reagents in the cyclization, and 2) the ability to obtain C1‐functionalized products by treating the reaction intermediate 1‐lithiobiphenylene with an electrophilic reagent. π‐Extended derivatives, such as benzobiphenylenes, dibenzobiphenylene, linear/angular [3]phenylenes, and biphenyleno[2,3‐b]biphenylenes, were synthesized similarly using suitable biaryls or teraryls.
