Les fondations et la « nouvelle philanthropie » : un changement de paradigmes scientifiques et politiques
Authors: Ducharme Élise , Lesemann Frédéric 
Published: May 2016

Les fondations de la « nouvelle philanthropie » portent un regard critique sur l’organisation sociale et sur l’action politique et tendent à imposer une nouvelle manière de gérer le social. Au Québec, la Fondation Lucie et André Chagnon s’inscrit dans la logique de ce mouvement. Les recherches effectuées à son sujet ont permis de faire ressortir quelques-uns des impacts de sa présence sur les acteurs du terrain de l’action sociale et communautaire. La situation constatée reflète une nouvelle logique d’action qui correspond à de nouveaux paradigmes que l’on retrouve à la fois dans le champ scientifique et dans le champ de la gouvernance, et qui concurrencent ceux sur lesquels reposent des années de pratiques de terrain.

AbstractElectromagnetic ion cyclotron (EMIC) waves are believed to be an important source of pitch angle scattering driven relativistic electron loss from the radiation belts. To date, investigations of this precipitation have been largely theoretical in nature, limited to calculations of precipitation characteristics based on wave observations and small‐scale studies. Large‐scale investigation of EMIC wave‐driven electron precipitation has been hindered by a lack of combined wave and precipitation measurements. Analysis of electron flux data from the POES (Polar Orbiting Environmental Satellites) spacecraft has been suggested as a means of investigating EMIC wave‐driven electron precipitation characteristics, using a precipitation signature particular to EMIC waves. Until now the lack of supporting wave measurements for these POES‐detected precipitation events has resulted in uncertainty regarding the driver of the precipitation. In this paper we complete a statistical study comparing POES precipitation measurements with wave data from several ground‐based search coil magnetometers; we further present a case study examining the global nature of this precipitation. We show that a significant proportion of the precipitation events correspond with EMIC wave detections on the ground; for precipitation events that occur directly over the magnetometers, this detection rate can be as high as 90%. Our results demonstrate that the precipitation region is often stationary in magnetic local time, narrow in L, and close to the expected plasmapause position. Predominantly, the precipitation is associated with helium band rising tone Pc1 waves on the ground. The success of this study proves the viability of POES precipitation data for investigating EMIC wave‐driven electron precipitation.
Homogenized moment tensor and the effect of near‐field heterogeneities on nonisotropic radiation in nuclear explosion
Authors: Burgos Gaël , Capdeville Yann , Guillot Laurent 
Published: May 2016

AbstractWe investigate the effect of small‐scale heterogeneities close to a seismic explosive source, at intermediate periods (20–50 s), with an emphasis on the resulting nonisotropic far‐field radiation. First, using a direct numerical approach, we show that small‐scale elastic heterogeneities located in the near‐field of an explosive source, generate unexpected phases (i.e., long period S waves). We then demonstrate that the nonperiodic homogenization theory applied to 2‐D and 3‐D elastic models, with various pattern of small‐scale heterogeneities near the source, leads to accurate waveforms at a reduced computational cost compared to direct modeling. Further, it gives an interpretation of how nearby small‐scale features interact with the source at low frequencies, through an explicit correction to the seismic moment tensor. In 2‐D simulations, we find a deviatoric contribution to the moment tensor, as high as 21% for near‐source heterogeneities showing a 25% contrast of elastic values (relative to a homogeneous background medium). In 3‐D this nonisotropic contribution reaches 27%. Second, we analyze intermediate‐periods regional seismic waveforms associated with some underground nuclear explosions conducted at the Nevada National Security Site and invert for the full moment tensor, in order to quantify the relative contribution of the isotropic and deviatoric components of the tensor. The average value of the deviatoric part is about 35%. We conclude that the interactions between an explosive source and small‐scale local heterogeneities of moderate amplitude may lead to a deviatoric contribution to the seismic moment, close to what is observed using regional data from nuclear test explosions.
Adaptive control for a class of uncertain linear parameter‐varying flight aircraft systems
Authors: Liu Chun‐sheng , Ye Qing , Zhang Shao‐jie 
Published: May 2016

SummaryThe concept of linear parameter‐varying (LPV) model has been developed as a convenient framework to describe a special class of uncertain LPV flight aircraft systems. In this paper, an adaptive control method for a class of uncertain LPV systems whose state‐space matrix elements are unknown affine functions of a set of measurable scalar parameters is presented. Firstly, the scalar parameters are separated from the state matrices such that the LPV model is rewritten as general unknown parameter model, then state feedback adaptive control laws, in both cases: the matched uncertainty and the unmatched uncertainty, are designed with the aim of controlling the system state to follow a desired trajectory. The sufficient condition of stability is derived using a Lyapunov equation, not a parameterized Lyapunov equation. Simulation tests based on a simple example and a nonlinear model of a transport aircraft are given to illustrate the effectiveness of the control algorithm and to demonstrate that the adaptive controller satisfies the performance requirement for an aircraft control system.

Palladium‐Catalyzed One‐Pot Synthesis of 5‐(1‐Arylvinyl)‐1H‐benzimidazoles: Overcoming the Limitation of Acetamide Partners
Authors: Naret Timothée , Retailleau Pascal , Bignon Jérôme , Brion Jean‐Daniel , Alami Mouad , Hamze Abdallah 
Published: May 2016

AbstractA new one‐pot palladium‐catalyzed process between N‐tosylhydrazones, N‐(dihalophenyl)‐imidates, and amines was designed. This reaction involves Barluenga cross‐coupling and N‐arylation followed by cyclization to produce functionalized benzimidazoles. During this transformation, one CC bond and two CN bonds were created by a single palladium‐catalyzed reaction. Depending on the starting materials, a library of 5‐(1‐arylvinyl)‐1H‐benzimidazoles was synthesized. Among several arylvinylbenzimidazole derivatives evaluated, one compound exhibits excellent antiproliferative activity in the nanomolar concentration range against human colon carcinoma cell lines (HCT‐116) and human lung adenocarcinoma epithelial cell lines (A549).magnified image

Published: May 2016

The purpose of this study is to assess the safety and efficacy of the combination of ofatumumab and bendamustine in patients with previously untreated or relapsed chronic lymphocytic leukemia. Patients received IV ofatumumab (cycle 1: 300 mg day 1 and 1,000 mg day 8; cycles 2–6: 1,000 mg on day 1 every 28 days) and IV bendamustine 90 mg m−2 (previously untreated) or 70 mg m−2 (relapsed) on days 1 and 2 of each 28‐day cycle, for up to 6 cycles. Forty‐four previously untreated and 53 relapsed patients were enrolled. Median age was 62.5 years (previously untreated) and 68 years (relapsed); relapsed patients had received a median of 1 (range 1–11) prior therapy. The investigator‐assessed overall response rate was 95% (43% complete response [CR]) for the previously untreated, and 74% (11% CR) for the relapsed patients. The regimen was well tolerated with 89% (previously untreated) and 85% (relapsed patients) receiving all 6 cycles. No unexpected toxicities were reported. Grade 3/4 events occurred in 57% of previously untreated, and 72% of relapsed patients. At ∼29 months’ follow‐up, the median progression‐free survival (PFS) was not reached for the previously untreated population, and the 28‐month PFS estimate was 72.3%. The median PFS for the relapsed population was 22.5 months (95% CI: 14.0–27.3 months). The combination of ofatumumab and bendamustine was well tolerated and effective in these previously untreated or relapsed populations. Am. J. Hematol. 91:900–906, 2016. © 2016 Wiley Periodicals, Inc.
N‐Alkyl Ammonium Resorcinarene Chloride Receptors for Guest Binding in Aqueous Environment
Authors: Beyeh Ngong Kodiah , Pan Fangfang , Ras Robin H. A. 
Published: May 2016

AbstractHost systems with guest binding ability in water and/or biological fluids are a current challenge in supramolecular host–guest chemistry. Here we present the first syntheses of water‐soluble N‐ethanol ammonium resorcinarene chlorides (NARCls) with terminal hydroxyl groups at the upper rim. The NARCls possess deep cavities and are shown to bind a variety of guest molecules such as linear and cyclic alkanes, linear halogenated alkanes, and aromatic fluorophores (naphthalene, p‐(phenylazo)phenol) in water through hydrophobic interactions, as well as 1,4‐dioxane (a water soluble guest) via hydrogen bonds. The receptors are monomeric in aqueous media and form 1:1 host–guest complexes with binding constants of up to 559 m−1 in D2O/MeOD (9:1, v/v) at 298 K. Solid‐state analysis in purely organic media, reveals a dimeric 2:2 capsule and a self‐included dimer of nanometer dimensions. The host–guest complexes are analyzed in solid state by single‐crystal X‐ray diffraction and in solution by 1H NMR and diffusion‐ordered NMR spectroscopy.

Published: May 2016

ABSTRACTOrexin A and B peptides and the receptor OX2R were studied in sea bass and goldfish gastroenteric tract by immunoblotting combined with densitometric analysis using NIH Image J software and immunohistochemical techniques. These teleost species present a different gut organization and diverse feeding habits. Immunoblotting experiments showed one band of 16 kDa corresponding to prepro‐orexin, and one band of 38 kDa corresponding to the OX2R receptor. Immunohistochemical localization of OXA and OXB was observed in the enteric nervous system throughout the gastroenteric tract of both species. OXA and OXB immunoreactive cells were found in the gastric and intestinal regions of sea bass, and were mainly found in the basal region of folds in intestinal bulb, and in the midgut and hindgut of goldfish. The distribution of OX2R was mainly detected in the mucosa of the gastroenteric tract of sea bass and goldfish. This distribution suggests an endocrine action of OXA and OXB in the gastrointestinal tract as well as involvement in the peripheral control of food intake and digestive processes in both species. This study might also serve to determine the productive factors in breeding and as a baseline for future experimental studies on the regulation of the gastroenteric functions in non‐mammalian vertebrates.

Published: May 2016

AbstractA rapid and sensitive liquid chromatography–tandem mass spectrometry (LC‐MS/MS) method has been developed and validated for simultaneous quantification of ginsenosides Rg1, Re and notoginsenoside R1 in human plasma. Chromatography was performed on Capcell Pak C18 MG II column using a binary gradient using mobile phase A (5 mm ammonium formate solution) and B (methanol, containing 5 mm ammonium formate) at a flow rate of 0.3 mL/min. The entire chromatographic run time was 3.2 min. Quantification was achieved using multiple reaction monitoring in positive mode using API 3000. This method was validated in terms of specificity, linearity, precision, accuracy, matrix effect and stability. The calibration curves were linear in the concentration range of 0.020–5.00 ng/mL for ginsenosides Rg1, Re and notoginsenoside R1. The lower limit of quantification (LLOQ) of this method was 0.020 ng/mL. The intra‐run and inter‐run precision values were within 12.31% for ginsenoside Rg1, 14.13% for ginsenoside Re and 11.46% for notoginsenoside R1 at their LLOQ levels. The samples were stable under all tested conditions. This method was successfully applied to study the pharmacokinetics of ginsenoside Rg1 and notoginsenoside R1 in 24 healthy volunteers following oral administration of 200 mg Sanqi Tongshu Enteric‐Pellets Capsule.
