Art/Cinéma/Queer

Published: August 2010

Résumé Le cinéma queer se déploie entre le cinéma expérimental, le journal intime, la vidéo plasticienne, le documentaire, la ﬁction onirique, la captation et le vidéo-tract militant. Dans l’article introductif, nous abordons plusieurs dimensions de cette création : l’une est le re ﬂet d’une pratique de l’art queer depuis des expériences situées, c’est le cas des cinémas d’Hervé Guibert, de David Wojnarowicz, de Raphaël Vincent ou du travail photographique de Del LaGrace Volcano, depuis les expériences du sida ou des trans’identités. Une autre pourrait être la tentative de constitution d’un cinéma sexuel, celui de Hans Scheirl ou Maria Beatty, explorations d’un corps explosé et « dégenré », qui connecte directement dé ﬁlement des images, transformations chimiques et corporelles, sensations inframentales, jouissance et pratiques sexuelles déterritorialisés. En ﬁn, nous nous arrêtons plus largement sur l’émergence d’un cinéma queer qui se fait lieu d’élaboration d’un contre-cinéma, soustraction au cinéma qui pose un regard hégémonique sur des sujets politiques subalternes. Le genre documentaire est alors creusé de l’intérieur par ce geste décolonisateur.
Grèce : révolte mineure ?
Authors: Matsas Ben 
Published: August 2010

Résumé Cet article présente une tentative, incertaine, de parler de la révolte de décembre en Grèce en général et sur la scène, tumultueuse, d’Athènes en particulier. Quelques considérations critiques, « cliniques » et politiques sur l’extrême-gauche sont suivies du désir de se déplacer vers les marges et les minorités. L’attention n’est pas moins portée aux « politiques de l’expérience » telles que le féminisme, qu’à diverses manifestations singulières du désir inconscient (Guattari).
Acrobaties face au désastre
Authors: Giordano Denis 
Published: August 2010

Résumé Contre la vague européenne de réformes normalisées de l’éducation supérieure, les activistes italiens, entre octobre 2008 et le printemps 2009, ont mobilisé une vague « anomale » de résistances caractérisées par un grand potentiel de transversalité et d’autonomie. On essaie ici de mesurer à la fois les forces d’inspiration dont ce mouvement reste porteur, et les raisons des difficultés qu’il a connues pour se brancher sur des dynamiques politiques plus vastes.
Une rébellion inachevée
Authors: Viveros Vigoya Mara , Cifuentes Alexander 
Published: August 2010

Résumé	Cet article rend compte des représentations des populations noires élaborées par la société colombienne depuis l’époque coloniale, en passant par la période républicaine et l’essor de l’idéologie du métissage jusqu’à nos jours, moment où la nation s’est redéfinie comme pluriethnique et multiculturelle. Les auteurs placent au centre de leur réflexion les droits et les aspirations des groupes sociaux minorisés, qui n’ont pas eu la possibilité de se représenter par eux-mêmes dans le processus de construction nationale. L’article étudie les difficultés subies par les Afrocolombien(ne)s, malgré leurs luttes et résistances, pour obtenir leur inclusion comme citoyen(ne)s à part entière dans un contexte hostile marqué par l’accentuation du conflit interne et du néolibéralisme.
On nous cache tout /on nous dit rien. On nous cache rien/on nous dit tout

Résumé D’emblée, une redondance : exposer sur la transmission. Le métasystème de l’art (critique, histoire de l’art, esthétique), nous expose à une essence médiatisée de l’œuvre. Mais « art » et « transmission » ne s’accordent pas avec tant d’évidence. Ainsi se présentent trois obstacles (hégémonie du mode « autoréflexif » de l’œuvre ; apparences d’une surmédiatisation ; prévalence du dispositif) que l’exposition Transmission s’est donnée pour gage de contourner.
Regarder et être regardé : une micro-politique de l'image
Authors: Lazzarato Maurizio 
Published: August 2010

Résumé La transmission apparaît ici au titre de dispositifs à réinventer. Avec le projet « Timescapes », Angela Melitopoulos bouleverse les dispositifs classiques de production de l’image et cristallise, au sein des mouvements diasporiques, une micropolitique dissensuelle où l’observation hiérarchique et univoque se mue en une perpétuelle négociation collective. Ainsi se trame la densité d’un projet déployé selon des coordonnées géopolitiques et identitaires discontinues, où la coopération technique permet, plus qu’une totalisation, la rencontre événementielle de subjectivités minoritaires : d’un Univers-bloc à un Univers-mosaïque.
Preparing for novelty with diverse training
Authors: Brunstein Angela , Gonzalez Cleotilde 
Published: August 2010

AbstractThis study investigated the ability to generalize acquired skills from training conditions to novel conditions, in a complex perceptual and cognitive task of luggage screening. We examined category and exemplar diversity during training for preparing learners to detect novel items during transfer. Category diversity was manipulated in terms of heterogeneity of training categories: Participants either trained with targets from one category or with targets from several categories. Exemplar diversity was manipulated between participants by presenting either a few or many exemplars for both category diversity conditions. Seventy‐two participants were trained to identify threats in pieces of luggage. Thereafter they were transferred to novel stimuli. Results can be summarized in support for the diversity of training hypothesis for preparing for novelty: To the best training for novel luggage screening situations is achieved using fewer items in a variety of categories.

Attitudes about memory dampening drugs depend on context and country
Authors: Newman Eryn J. , Berkowitz Shari R. , Nelson Kally J. , Garry Maryanne , Loftus Elizabeth F. 
Published: August 2010

AbstractWhen people take drugs such as propranolol in response to trauma, it may dampen their bad memories – tempering recall of a traumatic event. We examined people's attitudes toward these drugs. Americans and New Zealanders read about a hypothetical assault inserting themselves into a scenario as a victim attacked while serving on a peace keeping mission (soldier role) or while walking home from a job as a restaurant manager (civilian role). Then they told us whether they should receive a memory dampening drug, and whether they would want to take a memory dampening drug. Subjects were negatively disposed towards a memory dampening drug, but Americans who adopted the soldier role were more in favor of having access to the drug than those who adopted the civilian role. We discuss the implications of these findings in relation to an increasing trend in ‘cosmetic neurology’, medicating with the goal of enhancement, rather than therapy.

Performance Optimization of Polymer Solar Cells Using Electrostatically Sprayed Photoactive Layers
Authors: Kim Joon‐Sung , Chung Won‐Suk , Kim Kyungkon , Kim Dong Young , Paeng Ki‐Jung , Jo Seong Mu , Jang Sung‐Yeon 
Published: August 2010

AbstractPolymer solar cells (PSCs) are fabricated using a novel film deposition method, the electrostatic spray (e‐spray) technique. Stable atomization and uniform deposition of the polymer blend by e‐spray are achieved by manipulating the solution concentration, the solvent composition, and the electric field. The performance of PSCs is primarily influenced by the inherent film morphology of the e‐sprayed polymer‐blend active layers, which is significantly different from that of the conventional films that are formed using the spin‐coating (SC) method. The intrinsically formed interfacial boundaries between the e‐sprayed blend pancakes resist charge transport, which unfavorably influences device efficiency. The internal series resistance (RS) of the PSCs that are formed using the e‐spray method (e‐spray‐PSC) is significantly reduced by a solvent vapor soaking (SVS) treatment in addition to the conventional thermodynamic nanomorphology controls. The detailed relationship between the morphologies (film morphology and internal nanomorphology) and the RS is revealed using impedance spectroscopy. The performance of the e‐spray‐PSCs is comparable to those of the PSCs that are fabricated using the SC method under identical conditions. Therefore, the e‐spray method can be used to fabricate ultralow‐cost PSCs, because of the performance results combined with the intrinsic advantages that the e‐spray method is simple and has a low materials loss.
Multicolor Tunable Emission from Organogels Containing Tetraphenylethene, Perylenediimide, and Spiropyran Derivatives

Published: August 2010

AbstractA dendron‐substituted tetraphenylethene low molecular weight gelator (LMWG)compound, LMWG1, is designed and investigated. Gelation‐induced fluorescence enhancement is observed for the gel based on LMWG1 and its fluorescence can be reversibly tuned by varying the temperature of the ensemble. The photoinduced energy‐transfer can occur between LMWG1 and PI2 (perylene diimide) in the gel phase, but it cannot occur in the corresponding solution. The emission color of the gel of LMWG1 and PI2 can be tuned from cyan, yellow, to red by varying the concentration of PI2. By taking advantage of the photochromic transformation of spiropyran, the emission color of the organogels based on LMWG1 and SP3 can be switched by alternating UV and visible‐light irradiations. The emission color can also be tuned by varying the irradiation time. In this way, organogels based on LMWG1 with multiemission color can be achieved in the presence of SP3 after light irradiations.

AbstractGraphene, with its unique combination of physical and electronic properties, holds great promise for biosensor and bioelectronic applications. In this respect, the development of graphene solution‐gated field‐effect transistor (SGFET) arrays capable of operation in aqueous environments will establish the real potential of graphene in this rapidly emerging field. Here, we report on a facile route for the scalable fabrication of such graphene transistor arrays and provide a comprehensive characterization of their operation in aqueous electrolytes. An on‐chip structure for Hall‐effect measurements allows the direct determination of charge carrier concentrations and mobilities under electrolyte gate control. The effect of the solution‐gate potential on the electronic properties of graphene is explained using a model that considers the microscopic structure of water at the graphene/electrolyte interface. The graphene SGFETs exhibit a high transconductance and correspondingly high sensitivity, together with an effective gate noise as low as tens of μV. Our study demonstrates that graphene SGFETs, with their facile technology, high transconductance, and low noise promise to far outperform state‐of‐the‐art Si‐based devices for biosensor and bioelectronic applications.
The investigation of SCR reaction on sulfated CaO

Published: August 2010

AbstractThe catalytic activity of sulfated CaO in the selective catalytic reduction (SCR) reaction of NO with NH3 in the presence of O2 was investigated. In situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), Brunauer–Emmett–Teller (BET), SEM, XRD, NH3‐TPD (temperature programmed desorption), and NO‐TPD were used to characterize the catalyst of sulfated CaO and analytical grade CaSO4. The BET results indicated that the surface area decreased as the sulfation extent increased due to pore plug. SEM analysis revealed the surface morphology of the sulfated CaO with different sulfation extent. XRD results suggested that the sulfated CaO was hexagonal CaSO4. NH3‐TPD and NO‐TPD experiments indicated that NH3 was more likely to be absorbed on the sulfated CaO than NO, and as the sulfation extent increased, the acid sites reduced because of the decreasing surface area, but the acid strength of surface acidity increased. Based on the characterization and SCR reaction results, NH3 adsorption on CaO and CaSO4, and then reaction with O2 or NO would be the possible reaction route on sulfated CaO.

Toward a Concept of Stretch Coupling in Smooth Muscle: A Thesis by Lars Thuneberg on Contractile Activity in Neonatal Interstitial Cells of Cajal
Authors: Huizinga Jan D. , Lammers Wim J.E.P. , Mikkelsen Hanne B. , Zhu Yaohui , Wang Xuan‐Yu 
Published: August 2010

AbstractThe hypothesis was put forward by Thuneberg that rhythmically contracting interstitial cells of Cajal (ICC) were sensing stretch of the musculature and that this information was transmitted to smooth muscle cells via peg and socket contacts. The present study provides the evidence for the contractile nature of ICC as perceived by Thuneberg. The contractile activity is shown by video frame subtraction and by tracking areas of interest in sequential video frames. Thuneberg used neonatal ICC in culture maintained between two coverslips thereby allowing growth factors to quickly reach optimal concentrations. Contractions of ICC were seen to precede smooth muscle contractions. In addition, strong contractions were observed solely in branches of ICC. It is hoped that this communication will stimulate discussion about the contractile nature of ICC and that this phenomenon will eventually find its place amongst the physiological properties of the ICC networks of the gut musculature.

Biomass logistics as a determinant of second‐generation biofuel facility scale, location and technology selection
Authors: Stephen James D. , Mabee Warren E. , Saddler Jack N. 
Published: August 2010

AbstractFeedstock logistics, as dictated by biomass physical properties, location, and distribution, as well as transportation infrastructure, were shown to be a primary determinant of the scale, location, and technology selection of any future biorefineries. The maximum capacity of both biochemical‐ and thermochemical‐based second‐generation biofuel facilities was established based on feedstock logistics including delivery mode (road, rail, or ship), maximum number of deliveries by mode, feedstock type (whole logs, chips, pellets, or bio‐oil), and biofuel yield from those feedstocks. The world's largest ethanol plant, pulp mill, coal‐based power plant, and oil refinery were used to approximate maximum plant size for different technologies, and to set an upper limit on the number of deliveries logistically possible for each transport mode. It was apparent that thermochemical conversion to transportation biofuels was favored for large, multimodal coastal facilities that are able to receive imported biomass in the form of feedstock intermediates, such as pellets and bio‐oil (maximum capacities of 2844 and 6001 million liters gasoline equivalent (MLGE) respectively). Biochemically‐based conversion processes, primarily due to smaller economies of scale and the typical use of higher moisture content and undensified feedstocks, such as whole logs and chips, are better suited for smaller facilities (maximum 1405 and 1542 MLGE, respectively) that rely on local feedstocks delivered by truck and/or rail. It was also apparent that optimization of the feedstock‐intermediate‐product chain, including biomass densification for transportation and high conversion yield, is essential if the scale of the any second‐generation biofuels facility is to be maximized.

Involvement of mitochondrial activity in mediating ELF‐EMF stimulatory effect on human sperm motility

Published: August 2010

AbstractIt has recently been reported that the exposure of human spermatozoa to an extremely low frequency (ELF) electromagnetic field (EMF) with a square waveform of 5 mT amplitude and frequency of 50 Hz improves sperm motility. The functional relationship between the energy metabolism and the enhancement of human sperm motility induced by ELF‐EMF was investigated. Sperm exposure to ELF‐EMF resulted in a progressive and significant increase of mitochondrial membrane potential and levels of ATP, ADP and NAD+that was associated with a progressive and significant increase in the sperm kinematic parameters. No significant effects were detected on other parameters such as ATP/ADP ratio and energy charge. When carbamoyl cyanidem‐chlorophenylhydrazone (CICCP) was applied to inhibit the oxidative phosphorylation in the mitochondria, the values of energy parameters and motility in the sperm incubated in the presence of glucose and exposed to ELF‐EMF did not change, thus indicating that the glycolysis was not involved in mediating ELF‐EMF stimulatory effect on motility. By contrast, when pyruvate and lactate were provided instead of glucose, the energy status and motility increased significantly in ELF‐EMF‐treated sperm. Under these culture conditions, the inhibition of glycolitic metabolism by 2‐deoxy‐D‐glucose (DOG) again resulted in increased values of energy and kinematic parameters, indicating that gluconeogenesis was not involved in producing glucose for use in glycolysis. We concluded that the key role in mediating the stimulatory effects exerted by ELF‐EMF on human sperm motility is played by mitochondrial oxidative phosphorylation rather than glycolysis.

A numerical coefficient for evaluation of the environmental impact of electromagnetic fields radiated by base stations for mobile communications
Authors: Russo P. , Cerri G. , Vespasiani V. 
Published: August 2010

AbstractThe aim of this study is the development of an Electromagnetic Environmental Impact Factor (EEIF). This is a global parameter that represents the level of electromagnetic impact on a specific area due to the presence of radiating systems, such as base station (BS) antennas for mobile communications. The numerical value of the EEIF depends only on the electromagnetic field intensity, a well‐defined physical quantity that can easily be measured or computed. The paper describes the significant parameters of the field distribution adopted to evaluate the EEIF, and the assumptions used to develop a proper scale of values. Finally, some examples of application of the EEIF method are analyzed for real situations in a typical urban area. Bioelectromagnetics 31:613–621, 2010. © 2010 Wiley‐Liss, Inc.
The early years of retroviral protease crystal structures
Authors: Miller Maria 
Published: August 2010

AbstractSoon after its discovery, the attempts to develop anti‐AIDS therapeutics focused on the retroviral protease (PR)—an enzyme used by lentiviruses to process the precursor polypeptide into mature viral proteins. An urgent need for the three‐dimensional structure of PR to guide rational drug design prompted efforts to produce milligram quantities of this enzyme. However, only minute amounts of PR were present in the HIV‐1 and HIV‐2 viruses, and initial attempts to express this protein in bacteria were not successful. This review describes X‐ray crystallographic studies of the retroviral proteases carried out at NCI‐Frederick in the late 1980s and early 1990s and puts into perspective the crucial role that the total protein chemical synthesis played in unraveling the structure, mechanism of action, and inhibition of HIV‐1 PR. Notably, the first fully correct structure of HIV‐1 PR and the first cocrystal structure of its complex with an inhibitor (a substrate‐derived, reduced isostere hexapeptide MVT‐101) were determined using chemically synthesized protein. Most importantly, these sets of coordinates were made freely available to the research community and were used worldwide to solve X‐ray structures of HIV‐1 PR complexes with an array of inhibitors and set in motion a variety of theoretical studies. Publication of the structure of chemically synthesized HIV‐1 PR complexed with MVT‐101 preceded only by six years the approval of the first PR inhibitor as an anti‐AIDS drug. © 2010 Wiley Periodicals, Inc.

S‐acyl isopeptide method: Use of allyl‐type protective group for improved preparation of thioester‐containing S‐acyl isopeptides by Fmoc‐based SPPS

Published: August 2010

AbstractWe have studied the “S‐acyl isopeptide method” for the synthesis of peptides containing difficult sequences. The S‐acyl isopeptide, which contains a β‐thioester instead of the native N‐acyl bond at a Cys residue, can be converted into the target peptide via an S‐to‐N intramolecular acyl migration reaction. However, the synthesis of the S‐acyl isopeptide structure by Fmoc‐based SPPS is hampered by repetitive base treatments; decomposition of the thioester and the epimerization of the thioesterified residue are commonly observed. Here, we adopted allyloxycarbonyl (Aloc) protective group to avoid the problem. Catalytic amount of Pd in the presence of scavengers such as PhSiH3 and dimedone selectively removed the Aloc group with neither decomposition of the thioester structure nor epimerization at the thioesterified residue. A model pentapeptide and amylin(1‐12) with difficult sequences were efficiently synthesized by the improved S‐acyl isopeptides method. Finally, the isolated S‐acyl isopeptides were quantitatively converted into the desired peptides via the S‐to‐N intramolecular acyl migration reaction. The S‐acyl isopeptide method will be a useful method to prepare the difficult sequence‐containing peptides with Cys residue. © 2010 Wiley Periodicals, Inc.Biopolymers (Pept Sci) 96: 228–239, 2011.
Native chemical ligation in the synthesis of internally modified oligonucleotide–peptide conjugates
Authors: Diezmann Franziska , Eberhard Hendrik , Seitz Oliver 
Published: August 2010

AbstractPeptide–oligonucleotide conjugates have frequently been synthesized to improve cellular delivery of antisense or antigene compounds, to allow the immobilization of peptide and protein conjugates on DNA arrays, or to decorate nucleic acid architectures with peptide functions. In such applications, the site of conjugation is of little importance, and peptides have predominantly been appended to one of the terminal ends of the oligonucleotide by using an oxime‐, thioether‐, or disulfide‐linkage or native chemical ligation. We, herein, demonstrate the first coupling of peptides to sequence internal sites. This attachment mode provides better control of the spatial arrangement of peptides presented by self‐assembled nucleic acid scaffolds. Internal modification requires special phosphoramidite building blocks that can be used in automated DNA synthesis. For this purpose, Fmoc/StBu‐protected cysteine was attached via an aminopropargyl linker to the C5‐position of uridine. The rigid triple bond conferred a high reactivity in native chemical ligation reactions of 5–6mer peptide thioesters with up to 15 nucleotides long oligonucleotides. The desired peptide–oligonucleotide conjugates were obtained in high yields after purification. UV melt experiments revealed that the peptide modification does not hamper nucleic acid hybridization. This finding marked an important step in our research program devoted to studies of multivalent presentation of peptides via modular assembly of nucleic acid complexes. © 2010 Wiley Periodicals, Inc.
