Cabanyal Portes Obertes, se acabó ¿y ahora qué? Prácticas artísticas políticas y colaborativas en la ciudad
Authors: Martínez Arroyo Emilio José 
Published: October 2016

El evento de arte Cabanyal Portes Obertes, ha venido desarrollándose ininterrumpidamente desde 1998 hasta 2015 para revindicar la rehabilitación del barrio del Cabanyal de Valencia, convirtiéndose en una referencia de arte como herramienta al servicio del movimiento ciudadano en la visibilización de sus reivindicaciones. En 2015 fruto del movimiento ciudadano se consigue la retirada del proyecto de destrucción del Cabanyal y el inicio de su rehabilitación , en este momento Cabanyal Portes Obertes siente que sus objetivos han sido cumplido y por lo tanto plantea su desaparición como evento artístico. La nueva situación política nos obliga a reflexionar como artistas cuales pueden ser las formas más útiles que pueden adoptar las propuestas artísticas para seguir apoyando las reivindicaciones ciudadanas en el nuevo contexto del Cabanyal. Surgen así Cabanyal Arxiu Viu y CraftCabanyal dos proyectos artísticos colaborativos que acompañaran al movimiento ciudadano frente a los retos que aparecen en esta nueva situación.
La nouvelle trilogie de la Cour suprême du Canada relative à la liberté d’association : source de réjouissance pour les travailleurs autonomes ?
Authors: Choko Maude 
Published: October 2016

En janvier 2015, la Cour suprême du Canada a rendu une nouvelle trilogie relative à la protection constitutionnelle de la liberté d’association. Ce faisant, elle reconnaissait pour la première fois une protection constitutionnelle au « droit de grève » en vertu de la liberté d’association proclamée par l’article 2 d) de la Charte canadienne des droits et libertés. Par cette trilogie, la Cour suprême renversait également une décision antérieure en décidant que l’exclusion des membres de la Gendarmerie royale du Canada du régime établi par la Loi sur les relations de travail dans la fonction publique et leur inclusion dans un programme alternatif non syndical, imposée par le Règlement de la gendarmerie royale du Canada étaient inconstitutionnelles. Le présent texte se penche sur la nouvelle interprétation que donne la Cour suprême à la liberté d’association, en invoquant les obligations internationales du Canada en matière de liberté syndicale telle que prévue par les normes de l’Organisation internationale du travail. Il analyse l’impact de la trilogie sur les travailleurs autonomes qui ne sont couverts par aucun régime de relations du travail. Dans cette perspective, il évalue dans quelle mesure la nouvelle portée dévolue à la protection constitutionnelle garantie par l’article 2 d) de la Charte est de nature à favoriser l’exercice par ces travailleurs autonomes de leur liberté syndicale.
Pour en finir avec les Monomanes de Géricault : considérons leur rôle dans la construction du mythe de l’artiste
Authors: Jubinville Ginette 
Published: October 2016

Théodore Géricault’s Monomanes (Portraits of the Insane ; 1820s) were rediscovered in 1863, just four years before his first biography was published. This article examines this previously unstudied conjuncture in order to put to rest some of the myths surrounding these works and to show that their circulation contributed to the discourse on Géricault that was taking shape at the time. These five portraits have been described as displaying a duality that places them between art and psychiatry, between science and popular culture. This article argues that this resulted from the amalgamation of two distinct understandings of monomania : the scientific one at the time of their production and the popular one at the time of their rediscovery.
Broadband-sensitive cooperative upconversion emission of La(Ga0.5Sc0.5)O3:Er,Ni,Nb

Published: October 2016

Abstract
We systematically conducted time-resolved photoluminescence measurements on La(Ga0.5Sc0.5)O3:Er,Ni,Nb to elucidate the dominant mechanism of Ni2+-sensitized Er3+ upconversion emission at approximately 0.98 µm under 1.0–1.45-µm excitation, which could significantly improve the conversion efficiency of crystalline silicon solar cells. After detailed analysis using rate equations describing the energy transfer involved in the Ni2+ and Er3+ and upconversion, we concluded that the upconversion emission is dominated by the excitation of two Er3+ emitters due to the resonance energy transfer from two Ni2+ sensitizers, followed by further excitation to the initial state of the upconversion emission caused by another energy transfer between the two first-excited Er3+, i.e., cooperative upconversion.
Photomodulation of InGaZnO thin film transistors with interfacial silver nanoparticles

Published: October 2016

Abstract
Silver nanoparticles (Ag NPs) were inserted between indium gallium zinc oxide (IGZO) and a gate insulator to enhance the generation of plasmonic photocurrent with the illumination of visible light. Ag NPs were formed on a silicon dioxide gate insulator using a thermal evaporator and a post-annealing process. Then, an amorphous IGZO active channel layer was deposited on the Ag NPs using a sputter system. The prepared Ag NPs effectively absorbed a wide wavelength range of visible light due to plasmon effects. The IGZO thin film transistors (TFTs) with interfacial Ag NPs showed a large photocurrent due to the strong coupling between localized plasmons and electrical carriers in the active channel region of the TFTs. The prepared device showed good modulation behavior under visible light even though IGZO has a wide band gap. The results indicate that interfacial Ag NPs enabled the photomodulation of IGZO TFTs when exposed to a periodic signal of low-energy visible light. This work demonstrates a useful way to develop visible-light phototransistors based on a wide band gap semiconductor and plasmonic Ag NPs.
Theoretical study of relationships among resolution, line width roughness, and sensitivity of chemically amplified extreme ultraviolet resists with photodecomposable quenchers
Authors: Kozawa Takahiro , Santillan Julius Joseph , Itani Toshiro 
Published: October 2016

Abstract
The resolution of chemically amplified extreme ultraviolet (EUV) resists has reached 13–15 nm. However, the line width roughness (LWR) and sensitivity are still inadequate for their application to the high-volume production of semiconductor devices. In this study, the performance of chemically amplified resists with photodecomposable quenchers were investigated by simulation based on the sensitization and reaction mechanisms of chemically amplified EUV resists. The relationships among resolution, LWR, and sensitivity were evaluated in the half-pitch ranges of 12–16 nm. The requirements for 20 mJ cm−2 and 10% critical dimension (CD) LWR are considered to be within the physical limits in the half-pitch range of 12–16 nm when an optical image with a contrast of 1 (normalized image log slope of π) is given. Depending on the given image quality and the required sensitivity, the optimization of sensitizer concentration and the increase in resist absorption coefficient and/or effective reaction radius for deprotection are required to achieve 10% CD LWR.

Abstract
In this work, the first-ever growth of cubic-In2O3 at 1000 °C by halide vapor phase epitaxy (HVPE) was achieved, using gaseous InCl and O2 as precursors in a N2 flow. The growth rates of In2O3 layers on (001) β-Ga2O3 and (0001) sapphire substrates were 4.1 and 5.1 µm/h, respectively, even at the high growth temperature applied, which are approximately half the growth rate of β-Ga2O3 homoepitaxially grown by HVPE at 1000 °C. Theoretical thermodynamic analyses were also conducted, and results confirmed the growth of In2O3 at temperatures above 1000 °C by HVPE. The as-grown In2O3 layers were light yellow-green in color. The In2O3 layers grown on the (001) β-Ga2O3 and (0001) sapphire substrates exhibited an optical absorption edge at about 370 nm, in addition to n-type conductivity with electron concentrations of 2.7 × 1018 and 1.7 × 1018 cm−3, and electron mobilities of 16.2 and 22.7 cm2 V−1 s−1, respectively.
Expediting evidence synthesis for healthcare decision-making: exploring attitudes and perceptions towards rapid reviews using Q methodology
Authors: Kelly Shannon E. , Moher David , Clifford Tammy J. 
Published: October 2016

BackgroundRapid reviews expedite the knowledge synthesis process with the goal of providing timely information to healthcare decision-makers who want to use evidence-informed policy and practice approaches. A range of opinions and viewpoints on rapid reviews is thought to exist; however, no research to date has formally captured these views. This paper aims to explore evidence producer and knowledge user attitudes and perceptions towards rapid reviews.MethodsA Q methodology study was conducted to identify central viewpoints about rapid reviews based on a broad topic discourse. Participants rank-ordered 50 text statements and explained their Q-sort in free-text comments. Individual Q-sorts were analysed using Q-Assessor (statistical method: factor analysis with varimax rotation). Factors, or salient viewpoints on rapid reviews, were identified, interpreted and described.ResultsAnalysis of the 11 individual Q sorts identified three prominent viewpoints: Factor A cautions against the use of study design labels to make judgements. Factor B maintains that rapid reviews should be the exception and not the rule. Factor C focuses on the practical needs of the end-user over the review process.ConclusionResults show that there are opposing viewpoints on rapid reviews, yet some unity exists. The three factors described offer insight into how and why various stakeholders act as they do and what issues may need to be resolved before increase uptake of the evidence from rapid reviews can be realized in healthcare decision-making environments.

Published: October 2016

AbstractIntroductionIn patients with Alzheimer's disease (AD) and mild cognitive impairment, structural changes in the retina (i.e., reduced thicknesses of the ganglion cell and retinal nerve fiber layers and inclusion bodies that appear to contain beta‐amyloid protein [Ab]) have been previously reported. We sought to explore whether anatomic retinal changes are detectable in the preclinical stage of AD.MethodsA cross‐sectional study (as part of an ongoing longitudinal cohort study) involving 63 cognitively normal adults, all of whom have a parent with AD and subjective memory complaints. We compared neocortical amyloid aggregation (florbetapir PET imaging) to retinal spectral domain optical coherence tomography (SD‐OCT) markers of possible disease burden. Retinal biomarkers, including the number and surface area of retinal inclusion bodies and the thickness of retinal neuronal layers, were compared across groups with high vs. low neocortical beta‐amyloid load.ResultsThe surface area of inclusion bodies increased as a function of cortical amyloid burden. Additionally, there was a trend toward a selective volume increase in the inner plexiform layer (IPL; a layer rich in cholinergic activity) of the retina in Aβ+ relative to Aβ− participants, and IPL volume was correlated with the surface area of retinal inclusion bodies.DiscussionThese initial results suggest that retinal imaging may be a potential cost‐effective and noninvasive technique that can be used to identify those at‐risk for AD. Layer‐specific changes in the IPL and their association with surface area of inclusion bodies are discussed as a possible reflection of early inflammatory processes associated with cholinergic disruption and concurrent Ab accumulation in the neocortex.

OBJECTIVETo evaluate the impact of no-touch terminal room no-touch disinfection using ultraviolet wavelength C germicidal irradiation (UVGI) on C. difficile infection (CDI) rates on inpatient units with persistently high rates of CDI despite infection control measures.DESIGNInterrupted time-series analysis with a comparison arm.SETTING3 adult hematology-oncology units in a large, tertiary-care hospital.METHODSWe conducted a 12-month prospective valuation of UVGI. Rooms of patients with CDI or on contact precautions were targeted for UVGI upon discharge using an electronic patient flow system. Incidence rates of healthcare-onset CDI were compared for the baseline period (January 2013–December 2013) and intervention period (February 2014–January 2015) on study units and non–study units using a mixed-effects Poisson regression model with random effects for unit and time in months.RESULTSDuring a 52-week intervention period, UVGI was deployed for 542 of 2,569 of all patient discharges (21.1%) on the 3 study units. The CDI rate declined 25% on study units and increased 16% on non-study units during the intervention compared to the baseline period. We detected a significant association between UVGI and decrease in CDI incidence (incidence rate ratio [IRR], 0.49; 95% confidence interval [CI], 0.26–0.94; P=.03) on the study units but not on the non-study units. The impact of UVGI use on average room-cleaning time and turnaround time was negligible compared to the baseline period.CONCLUSIONSTargeted deployment of UVGI to rooms of high-risk patients at discharge resulted in a substantial reduction of CDI incidence without adversely impacting room turnaround.Infect Control Hosp Epidemiol 2016;1–6
Population size, distribution and status of the remote and Critically Endangered Bawean deer Axis kuhlii
Authors: Rahman Dede Aulia , Gonzalez Georges , Aulagnier Stéphane 
Published: October 2016

AbstractConservation of rare ungulates requires reliable population size estimates and distribution maps for prioritizing investments and assessing the effectiveness of conservation measures. We used both camera trapping and a random encounter model approach, and faecal pellet group counts, to update the range and population size of the Bawean deer Axis kuhlii in the Bawean Island Nature Reserve and Wildlife Sanctuary, Indonesia. We studied 2-month periods to fulfil the assumption of population closure. Both methods provided similar population density estimates (higher in the dry season) of c. 227–416 individuals. The estimated range of the species is significantly narrower than previously reported. The main threats (habitat loss as a result of illegal logging, and disturbance by dogs and hunters) are ongoing. Based on these results we suggest that the species should retain its Critically Endangered status on the IUCN Red List.
Molecular characterization and detection of variants of Taenia multiceps in sheep in Turkey
Authors: SONMEZ BETUL , KOROGLU ERGUN , SIMSEK SAMI 
Published: October 2016

SUMMARYTaenia multiceps is a cestode (family Taeniidae) that in its adult stage lives in the small intestine of dogs and other canids. The metacestode, known as Coenurus cerebralis, is usually found in the central nervous system including brain and spinal card in sheep and other ruminants. The presence of cysts typically leads to neurological symptoms that in the majority of cases result in the death of the animal. Coenurosis could cause high losses in sheep farms because the disease commonly affects young animals. A total of 20 C. cerebralis isolates collected from naturally infected sheep in Mardin province of Turkey were characterized through the polymerase chain reaction and sequencing of a fragment of cytochrome c oxidase subunit 1 (CO1) gene. The results showed that the CO1 gene sequences were highly conserved in C. cerebralis isolates. Phylogenetic analysis based on partial CO1 gene sequences revealed that C. cerebralis isolates were composed of three different variants.

SUMMARYEukaryotic 5S rRNA, synthesized by RNA polymerase III (Pol III), is an essential component of the large ribosomal subunit. Most organisms contain hundreds of 5S rRNA genes organized into tandem arrays. However, the genome of the protozoan parasiteLeishmania majorcontains only 11 copies of the 5S rRNA gene, which are interspersed and associated with other Pol III-transcribed genes. Here we report that, in general, the number and order of the 5S rRNA genes is conserved between different species ofLeishmania. While in most organisms 5S rRNA genes are normally associated with the nucleolus, combined fluorescentin situhybridization and indirect immunofluorescence experiments showed that 5S rRNA genes are mainly located at the nuclear periphery inL. major. Similarly, the tandemly repeated 5S rRNA genes inTrypanosoma cruziare dispersed throughout the nucleus. In contrast, 5S rRNA transcripts inL. majorwere localized within the nucleolus, and scattered throughout the cytoplasm, where mature ribosomes are located. Unlike other rRNA species, stable antisense RNA complementary to 5S rRNA is not detected inL. major.
Efficient and selective N-alkylation of amines with alcohols catalysed by manganese pincer complexes

Published: October 2016

AbstractBorrowing hydrogen (or hydrogen autotransfer) reactions represent straightforward and sustainable C–N bond-forming processes. In general, precious metal-based catalysts are employed for this effective transformation. In recent years, the use of earth abundant and cheap non-noble metal catalysts for this process attracted considerable attention in the scientific community. Here we show that the selective N-alkylation of amines with alcohols can be catalysed by defined PNP manganese pincer complexes. A variety of substituted anilines are monoalkylated with different (hetero)aromatic and aliphatic alcohols even in the presence of other sensitive reducible functional groups. As a special highlight, we report the chemoselective monomethylation of primary amines using methanol under mild conditions.
Mechanism of pH-dependent activation of the sodium-proton antiporter NhaA

Published: October 2016

AbstractEscherichia coli NhaA is a prototype sodium-proton antiporter, which has been extensively characterized by X-ray crystallography, biochemical and biophysical experiments. However, the identities of proton carriers and details of pH-regulated mechanism remain controversial. Here we report constant pH molecular dynamics data, which reveal that NhaA activation involves a net charge switch of a pH sensor at the entrance of the cytoplasmic funnel and opening of a hydrophobic gate at the end of the funnel. The latter is triggered by charging of Asp164, the first proton carrier. The second proton carrier Lys300 forms a salt bridge with Asp163 in the inactive state, and releases a proton when a sodium ion binds Asp163. These data reconcile current models and illustrate the power of state-of-the-art molecular dynamics simulations in providing atomic details of proton-coupled transport across membrane which is challenging to elucidate by experimental techniques.

AbstractThe first hydrogenation step of benzene, which is endergonic in the electronic ground state (S0), becomes exergonic in the first triplet state (T1). This is in line with Baird’s rule, which tells that benzene is antiaromatic and destabilized in its T1state and also in its first singlet excited state (S1), opposite to S0, where it is aromatic and remarkably unreactive. Here we utilized this feature to show that benzene and several polycyclic aromatic hydrocarbons (PAHs) to various extents undergo metal-free photochemical (hydro)silylations and transfer-hydrogenations at mild conditions, with the highest yield for naphthalene (photosilylation: 21%). Quantum chemical computations reveal that T1-state benzene is excellent at H-atom abstraction, while cyclooctatetraene, aromatic in the T1and S1states according to Baird’s rule, is unreactive. Remarkably, also CVD-graphene on SiO2is efficiently transfer-photohydrogenated using formic acid/water mixtures together with white light or solar irradiation under metal-free conditions.
Sensing the quantum limit in scanning tunnelling spectroscopy

Published: October 2016

AbstractThe tunnelling current in scanning tunnelling spectroscopy (STS) is typically and often implicitly modelled by a continuous and homogeneous charge flow. If the charging energy of a single-charge quantum sufficiently exceeds the thermal energy, however, the granularity of the current becomes non-negligible. In this quantum limit, the capacitance of the tunnel junction mediates an interaction of the tunnelling electrons with the surrounding electromagnetic environment and becomes a source of noise itself, which cannot be neglected in STS. Using a scanning tunnelling microscope operating at 15 mK, we show that we operate in this quantum limit, which determines the ultimate energy resolution in STS. The P(E)-theory describes the probability for a tunnelling electron to exchange energy with the environment and can be regarded as the energy resolution function. We experimentally demonstrate this effect with a superconducting aluminium tip and a superconducting aluminium sample, where it is most pronounced.
