Média-activisme revisité
Authors: Berardi Franco , Neyrat Frédéric 
Published: February 2013

Résumé Si le média-activisme est parvenu à libérer des espaces d’expression, il n’a pas su empêcher les médias dominants, institutionnels et privés, de se réapproprier cette libération. À travers ses effets de saturation et de fragmentation, le « sémiocapitalisme » nous a fait la peau. Les médias dominants ont détruit les médiations individuelles et collectives par leur envoûtement : leur vol du temps et de la sensibilité. C’est la dimension esthétique que le média-activisme doit aujourd’hui investir, d’abord comme art, c’est-à-dire par une nouvelle production de la sensibilité, ensuite comme thérapeutique, c’est-à-dire comme soin apporté à nos appareils bio-médiatiques amoindris.
Les drones : nouveau médium de guerre ?
Authors: Karatsioli Barbara 
Published: February 2013

Résumé Les drones, ces avions sans pilote, miniaturisables à merci, qu’on envoie aujourd’hui espionner ou bombarder des lieux de conflits lointains, ne sont pas tant des « armes » ou des « produits », que des médiums : des matérialisations inquiétantes de médiations incontrôlées et incontrôlables, destinées à venir hanter et menacer ceux qui prétendent s’en servir. Cet article mène l’enquête sur leurs usages et leurs perceptions, offrant un exemple paradigmatique des inquiétants objets rendus possibles par la médiatisation croissante de notre planète et de nos vies.
En marchant avec une multitude de spectres prismatiques
Authors: Bardini Thierry 
Published: February 2013

Résumé Une longue histoire relie le développement des technologies médiatiques aux ruminations sur les spectres et les fantômes. Les manifestations de rue du « printemps érable » à Montréal ont permis de revivre cette histoire en condensé : les spectres y sont apparus, dans l’ombre du simulacre de gouvernement avec son attirail de loi spéciale, de propagande mass-médiatique et de répression, dans une expérience glorieuse du temps réel. Cette expérience a surtout permis de faire apparaître d’autres spectres, prismatiques, rigolards et libérateurs, à mi-chemin entre les potentiels inédits des nouveaux médias et la vieille pratique de marcher dans une rue ensemble.
Pour la sécurité alimentaire : restaurer la responsabilité d'État
Authors: Paré Frédéric 
Published: February 2013

Résumé Que nous suggère Jean-Jacques Rousseau, né il y a 300 ans, au sujet du rôle de l’État ? « La volonté générale, écrit-il, peut seule diriger les forces de l’État selon la fin de son institution (création), qui est le bien commun ; car, si l’opposition des intérêts particuliers a rendu nécessaire l’établissement des sociétés, c’est l’accord de ces mêmes intérêts qui l’a rendu possible. C’est ce qu’il y a de commun dans ces différents intérêts qui forme le lien social... » Les aliments sont aujourd’hui produits, transformés, emballés, transportés et commercialisés par des entreprises mises en concurrence entre elles à l’échelle planétaire. Mais la sécurité alimentaire nationale, fondée sur des ressources nationales, n’est-elle pas de l’ordre du contrat social ? La souveraineté alimentaire se définit comme le droit des peuples, des États, à gouverner les activités des « opérateurs alimentaires », aux fins de cette sécurité alimentaire, du bien commun.
Molecular Basis of DNA Recognition in the Immune System
Authors: Atianand Maninjay K. , Fitzgerald Katherine A. 
Published: February 2013

Abstract
Recognition of microbial nucleic acids is one strategy by which mammalian hosts respond to infectious agents. Intracellular DNA that is introduced into cells during infection elicits potent inflammatory responses by triggering the induction of antiviral type I IFNs and the maturation and secretion of inflammatory cytokines, such as TNF-α, IL-1β, and IL-18. In addition, if nucleases, such as DNase II or DNase III (Trex1), fail to clear self-DNA, accumulated DNA gains access to intracellular compartments where it drives inflammatory responses leading to autoimmune disease. In this review, we discuss a rapidly evolving view of how cytosolic DNA-sensing machineries coordinate antimicrobial immunity and, if unchecked, lead to autoimmune disease.

Published: February 2013

AbstractIn India, prostate cancer has an incidence rate of 3.9 per 100,000 men and is responsible for 9% of cancer-related mortality. It is the only malignancy that is diagnosed with an apparently blind technique, i.e., transrectal sextant biopsy. With increasing numbers of high-Tesla magnetic resonance imaging (MRI) equipment being installed in India, the radiologist needs to be cognizant about endorectal MRI and multiparametric imaging for prostate cancer. In this review article, we aim to highlight the utility of multiparamteric MRI in prostate cancer. It plays a crucial role, mainly in initial staging, restaging, and post-treatment follow-up.
Atypical femoral fractures related to bisphosphonate therapy
Authors: Jain Tarun Pankaj , Thorn Murray 
Published: February 2013

AbstractBisphosphonates (BP) are a commonly prescribed class of drugs for the prevention of osteoporosis-related fractures. Paradoxically, however, they have recently been linked to atypical fractures in the shaft of the femur. Since many physicians including radiologists, are not aware of this entity, the incidence is likely underreported. These fractures usually occur in the sub-trochanteric region of the femur in the setting of low-energy trauma. It starts as a fracture line involving the lateral cortex and then progresses medially to give rise to a complete fracture. The fracture line is usually transverse, and there is a medial spike associated with a complete fracture. These fractures can be bilateral. Awareness of these atypical fractures and their radiological appearance should enable their early and accurate detection and thus lead to specific treatment.

Published: February 2013

Purpose. To discuss the role of mathematical modeling in studying ocular hemodynamics, with a focus on glaucoma. Methods. We reviewed recent literature on glaucoma, ocular blood flow, autoregulation, the optic nerve head, and the use of mathematical modeling in ocular circulation. Results. Many studies suggest that alterations in ocular hemodynamics play a significant role in the development, progression, and incidence of glaucoma. Although there is currently a limited number of studies involving mathematical modeling of ocular blood flow, regulation, and diseases (such as glaucoma), preliminary modeling work shows the potential of mathematical models to elucidate the mechanisms that contribute most significantly to glaucoma progression. Conclusion. Mathematical modeling is a useful tool when used synergistically with clinical and laboratory data in the study of ocular blood flow and glaucoma. The development of models to investigate the relationship between ocular hemodynamic alterations and glaucoma progression will provide a unique and useful method for studying the pathophysiology of glaucoma.
Fatigue Damage Behavior of Freestanding 40 µm‐Thick Nickel Foils for MEMS Applications
Authors: Xu Jin , Zhang Guang‐Ping 
Published: February 2013

AbstractFatigue damage behavior of freestanding 40 µm‐thick Ni foils was investigated. We found that there were evident differences in fatigue behaviors of the foils loaded normal to and parallel to the rolling direction. EBSD analyses revealed that fatigue cracking along grain boundaries (GBs) or slip bands in two kinds of the foils depended on the difference in Schmid factor of the grains along both sides of the GBs and the misorientation angle of the GB. Fatigue damage mechanism was discussed.
Oligopoly and Price Transmission in Turkey's Fluid Milk Market
Authors: Tekgüç Hasan 
Published: February 2013

ABSTRACTFarmers and consumers suspect that processing firms abuse their power in the milk marketing chain by engaging in price fixing behavior. The author employs threshold autoregressive and moment threshold autoregressive tests, and contrary to expectations, finds evidence for a downward trend in wholesale milk price without a corresponding decline in farm‐gate prices. The downward trend coincides with increased competition in the dairy industry and with the growing market share of the formal sector at the expense of the informal sector. Major dairy processing firms expand their market share and yet continue to enjoy healthy profits thanks to increasing returns due to economies of scale in their processing and distribution operations in a growing market.

Published: February 2013

ABSTRACTStudy of drying characteristics and kinetics of coal is necessary in order to optimize drying operation and design a dryer in industrial scale. Drying characteristics of Chinese lignite was investigated experimentally using thermogravimetric method, and the effect of drying variables on drying rate was systematically studied. For CFD modeling and scale‐up purposes, it is useful to have an algebraic equation that describes the drying process of lignite. Therefore, different thin layer drying models given in the literature were employed to analyze coal drying kinetics under different conditions. During studying the consistency of all the models, statistical tests such as χ2, residual sum of squares (RSS), F‐value, and the coefficient of determination R2 were employed. It was found that the Midilli–Kucuk model best describes the drying process within 99.9% accuracy. The effects of drying temperature and coal sample weight on the constants and coefficients of the selected model were also studied by multiple regression analysis. Apparent diffusion coefficient of moisture from sample was calculated using the experimental kinetics data. Higher drying temperatures and smaller sample weights resulted in higher diffusion coefficient, which was consistent with experimental data. Activation energy of moisture evaporation calculated from Arrhenius equation for drying process was 21.17 kJ/mol. The selected algebraic drying model can be used for CFD modeling during scale‐up of drying facility for industrial applications. © 2013 Curtin University of Technology and John Wiley & Sons, Ltd.
Essential work of fracture of poly(ϵ‐caprolactone)/boehmite alumina nanocomposites: Effect of surface coating
Authors: Tuba Ferenc , Khumalo Vincent M. , Karger‐Kocsis József 
Published: February 2013

AbstractThe essential work of fracture (EWF) approach was adopted to reveal the effect of nanofillers on the toughness of poly (ϵ‐caprolactone) (PCL)/boehmite alumina (BA) nanocomposites. Synthetic BA particles with different surface treatments were dispersed into the PCL matrix by extrusion melt compounding. The morphology of the composites was studied by scanning electron microscopy. Differential scanning calorimetry and wide‐angle X‐ray scattering were used to detect changes in the crystalline structure of PCL. Also, mode I type EWF tests, dynamic mechanical analysis, and quasi‐static tensile tests were applied to study the effect of the BA nanofillers on the mechanical properties of the nanocomposites. BA was homogeneously dispersed and acted as heterogeneous crystallization nucleant and a nonreinforcing filler in PCL. The tensile modulus and yield strength slightly increased and the yield strain decreased with increasing BA content (up to 10 wt %). The effect of the BA surface treatment with octylsilane was negligible by contrast to that with alkylbenzene sulfonic acid (OS2). Like the tensile mechanical data, the essential and nonessential work of fracture parameters did not change significantly either. The improved PCL/BA adhesion in case of OS2 treatment excluded the usual EWF treatise. This was circumvented by energy partitioning between yielding and necking. The yielding‐related EWF decreased, whereas the nonessential EWF increased with BA content and with better interfacial adhesion. This was attributed to the effect of matrix/filler debonding. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
Modification of ramie fabric with a metal‐ion‐doped flame‐retardant coating
Authors: Wang Lili , Zhang Tao , Yan Hongqiang , Peng Mao , Fang Zhengping 
Published: February 2013

AbstractTransition‐metal‐ion‐doped flame‐retardant coatings were constructed on the surface of ramie fabrics by a layer‐by‐layer (LbL) assembly technique to investigate possible cooperative actions that could improve the fabric's flame‐retardant efficiency. We found that these functional coatings, consisting of poly(vinylphosphonic acid) (the anionic layer) and branched polyethylenimine/cupric or zinc ions (the cationic layer), improved the fire retardancy of the ramie fabrics remarkably. Attenuated total reflectance–Fourier transform infrared (FTIR) spectroscopy and energy dispersive X‐ray spectroscopy demonstrated the successful LbL assembly process and the incorporation of metal ions into the coating. Thermogravimetric analysis coupled with FTIR spectrometry, vertical flame testing, and microscale combustion calorimetry confirmed the improved thermal stability and reduced flammability of the coated ramie fabrics. All of the results show that the metal‐ion‐doped flame‐retardant coatings not only dramatically increased the residues but also retained the original weave structure and fiber morphology of ramie fabrics well. The enhanced flame‐retardant efficiency may have been caused by the lower decomposition temperature of the flame‐retardant coating, as promoted by cupric and zinc ions, and as a result, may have helped the flame‐retardant activity to take place earlier. © 2013 Wiley Periodicals, Inc.

Raster was Yesterday: Using Vector Engines to Process Geophysical Data
Authors: Schmidt Armin , Tsetskhladze Gocha 
Published: February 2013

ABSTRACTTools for the processing of raster data are well developed, but noisy data still pose considerable challenges. If anomalies are broken up into isolated individual readings, for example due to high noise levels, it may still be possible for a human interpreter to recognize the isolated readings as being part of a single anomaly. However, such a concept of neighbourhood is difficult to implement with raster tools and an alternative, vector‐based approach is presented here. By converting the measured raster data into polygons, it is possible to undertake shape and neighbourhood analysis to process the data. This allows discriminating, reshaping and merging of the anomalies based on their spatial location relative to each other (neighbourhood) and with respect to the size of each anomaly. The added advantage of this approach is the possibility to use the processed vector data as a basis for interpretation and visualization diagrams in two‐ and three dimensions. This method is applied to the GPR survey of a necropolis at Pessinus, showing several types of grave monuments. Copyright © 2013 John Wiley & Sons, Ltd.
Continuous Procrustes Distance Between Two Surfaces
Authors: Al‐Aifari Reema , Daubechies Ingrid , Lipman Yaron 
Published: February 2013

AbstractThe Procrustes distance is used to quantify the similarity or dissimilarity of (three‐dimensional) shapes and extensively used in biological morphometrics. Typically each (normalized) shape is represented by N landmark points, chosen to be homologous, as far as possible, and the Procrustes distance is then computed as
$\inf_{R}\sum_{j=1}^N \|Rx_j-x'_j\|^2$, where the minimization is over all euclidean transformations, and the correspondences $x_j \leftrightarrow x'_j$
are picked in an optimal way.The discrete Procrustes distance has the drawback that each shape is represented by only a finite number of points, which may not capture all the geometric aspects of interest; a need has been expressed for alternatives that are still easy to compute. We propose in this paper the concept of continuous Procrustes distance and prove that it provides a true metric for two‐dimensional surfaces embedded in three dimensions. We also propose an efficient algorithm to calculate approximations to this new distance. © 2012 Wiley Periodicals, Inc.
A framework of data caching for improving decoding efficiency of opportunistic network coding
Authors: Liu Qinglong , Feng Gang 
Published: February 2013

SUMMARYThroughput performance of wireless networks can be enhanced by applying network coding (NC) technique based on opportunistic listening. The packets sent or overheard by a network node should be locally cached for the purpose of possible future decoding. How to manage the cache to reduce the overhead incurred in performing NC and, meanwhile, exploit performance gain is an interesting issue that has not been deeply investigated. In this paper, we present a framework for packet caching policy in multihop wireless networks, aiming at improving decoding efficiency, and thus throughput gain of NC. We formulate the caching policy design as an optimization problem for maximizing decoding utility and derive a set of optimization rules. We propose a distributed network coding caching policy (NCP), which can be readily incorporated into various existing NC architectures to improve NC performance gain. We theoretically analyze the performance improvement of NCP over completely opportunistic NC (COPE). In addition, we use simulation experiments based on ns‐2 to evaluate the performance of NCP. Numerical results validate our analytical model and show that NCP can effectively improve the performance gain of NC compared with COPE. Copyright © 2013 John Wiley & Sons, Ltd.
Geographical origin of Leucobryum boninense Sull. & Lesq. (Leucobryaceae, Musci) endemic to the Bonin Islands, Japan

Published: February 2013

AbstractLeucobryum boninense is endemic to the Bonin Islands, Japan, and its related species are widely distributed in Asia and the Pacific. We aimed to clarify the phylogenetic relationships among Leucobryum species and infer the origin of L. boninense. We also describe the utility of the chloroplast trnK intron including matK for resolving the phylogenetic relationships among Leucobryum species, as phylogenetic analyses using trnK intron and/or matK have not been performed well in bryophytes to date. Fifty samples containing 15 species of Leucobryum from Asia and the Pacific were examined for six chloroplast DNA regions including rbcL, rps4, partial 5′ trnK intron, matK, partial 3′ trnK intron, and trnL‐F intergenic spacer plus one nuclear DNA region including ITS. A molecular phylogenetic tree showed that L. boninense made a clade with L. scabrum from Japan, Taiwan and, Hong Kong; L. javense which is widely distributed in East and Southeast Asia, and L. pachyphyllum and L. seemannii restricted to the Hawaii Islands, as well as with L. scaberulum from the Ryukyus, Japan, Taiwan, and southeastern China. Leucobryum boninense from various islands of the Bonin Islands made a monophylic group that was closely related to L. scabrum and L. javense from Japan. Therefore, L. boninense may have evolved from L. scabrum from Japan, Taiwan, or Hong Kong, or L. javense from Japan. We also described the utility of trnK intron including matK. A percentage of the parsimony‐informative characters in trnK intron sequence data (5.8%) was significantly higher than that from other chloroplast regions, rbcL (2.4%) and rps4 (3.2%) sequence data. Nucleotide sequence data of the trnK intron including matK are more informative than other chloroplast DNA regions for identifying the phylogenetic relationships among Leucobryum species.

Published: February 2013

AbstractIn this paper we report the structure and the fabrication process of the new microelectromechanical systems (MEMS) Fabry‐Perot Tunable Filter (FPTF) device with Ag alloy mirror which is tunable in the wide wavelength range of visible light. The device has a very simple structure, which consists of two substrates bonded by a novel bonding technology, polymer films, and inert gas plasma treatment. We confirmed that the wavelength of the first‐order transmission peak of the fabricated device can be adjusted to a range of 400 to 700 nm by applying the different DC voltage. Our MEMS FPTF device successfully operates in the wide wavelength range of visible light and shows good agreement with simulation results. © 2013 Wiley Periodicals, Inc.

Published: February 2013

AbstractIn this study, we investigate the loss reduction effect by stator‐teeth slits in turbine generators on the basis of electromagnetic field analysis and basic experiments. First, the loss reduction effect in the generator is estimated by the 3D finite element method and the theoretical solution of eddy current loss. Next, an experiment using a simple model that simulates the stator‐core ends of the turbine generator is carried out. It is clarified that the loss reduction effect by the slits depends on the frequency, flux density, and permeability of the stator teeth because the loss reduction effect weakens with the skin effect. © 2013 Wiley Periodicals, Inc.
