O pênis fala coisas que eu não sei dizer: para pensar em uma nova história do masculino
Authors: Ratts Júnior
Published: April 2018

Este trabalho busca refletir quais novas narrativas (ou histórias) sobre o gênero masculino podem ser desenvolvidas em oposição à História como a conhecemos e de que forma isto pode ser realizado através da arte e, mais precisamente, pela fotografia homoerótica/homoafetiva produzida por homossexuais masculinos. Para tanto, tornar-se imprescindível uma problematização do fazer histórico tradicional e de como essa prática construiu corpos e imaginários sobre os corpos que vigoram ainda nos dias atuais a fim de que seja possível discorrer sobre ações no campo da arte e da sociologia que permitam a construção de uma nova realidade para o gênero masculino.
“O São João é gay!!”: horizontes interpretativos sobre as perfomances trans na festa junina no Ceará
Authors: Barroso Hayeska Costa
Published: April 2018

O presente artigo tem por objetivo tecer reflexões iniciais sobre as perfomances trans na festa junina no Ceará, particularmente a partir do protagonismo de travestis, drag queens e transexuais neste cenário, no ano de 2015. O recorte empírico, neste primeiro momento, toma por base o trabalho de campo em dois concursos nos quais foram escolhidas a Miss Caipira Gay 2015, promovido pela Quadrilha Ceará Junino, e os Destaques Fequajuce (Federação de Quadrilhas Juninas no Ceará) 2015, dentre eles a Rainha da Diversidade. Além dessa imersão, foi entrevistado o atual representante cearense no Primeiro Concurso Nacional para a escolha da Rainha Gay do Brasil, o qual performatiza a Diva Adriana Séfora. As performances trans nos festejos juninos ratificam o pressuposto teórico de que, sim, todas as identidades de gênero são instáveis e encerram possibilidades de agência e subversão por parte dos indivíduos, isso porque não estamos falando de uma simples encenação de um processo histórico em constante devir. A instabilidade dos binarismos assentados na lógica homem-macho e mulher-fêmea e gay e hétero confirmam o paradoxo do gênero nas festas juninas: as performances trans só devem ser consideradas subversivas quando puserem em xeque esses mesmos binarismos e não quando o reforçarem. Se não são de todo subversivas, pois não permitem a descaracterização da díade masculino/feminino, explícita por meio das coreografias e indumentárias, ao menos os desestabilizam.
Pesquisa bailarina: a dança como metáfora da desconstrução do corpo docente generificado
Authors: Rosa Rogério Machado , Orlandi Renata
Published: April 2018

Este texto é inspirado na releitura de uma pesquisa de mestrado que discutiu o processo de diferenciação do/no corpo-masculino-docente. A partir da realização de entrevistas, instituiu-se problematizações em torno de narrativas biográficas de cinco (5) professores de Ensino Médio. Fazemos aqui uma reimersão na dissertação buscando cartografar os afetos que, na movediça trama da pesquisa, produziram deslocamentos e derivas na temática em estudo. Elegemos passagens das narrativas de alguns dos professores participantes da pesquisa como dispositivos movimentadores das reflexões propostas. A dança como “personagem conceitual” ganha destaque na medida em que é tomada como metáfora inspiradora e anunciadora de diferenças criadas pela dinâmica imbricação corpo-gênero-pesquisa. Para nós, autor e autora, e também para os professores participantes da pesquisa, a docência parece significar um lugar onde criamos heterotopias. Nela, nossos corpos contestam a suposta univocidade em torno da experimentação e expressão de gênero, sexualidade e corporeidade. Afirmam devires nomádicos, portanto.
Lésbicas negras, identidades interseccionais
Authors: Silva Ariana Mara
Published: April 2018

O objetivo do presente artigo é refletir sobre as identidades lésbicas negras enquanto interseccionais e construídas em uma relação dialética com o universo de representações de uma sociedade machista, racista e lesbofóbica. Através de alguns apontamentos sobre fascismo simbólico e colonialidade do poder procura-se um entendimento sobre como se deu a construção das identidades latino-americanas, bem como as funções e posições impostas a elas. Esse artigo conta também com uma reflexão sobre as resistências existentes analogamente a essas imposições.
Universidade, gênero e movimentos sociais (Decálogo)
Authors: Bento Berenice

Essas questões explodiram durante a ocupação de um banheiro realizada por estudantes de vários cursos da UFRN. O artigo se propõe a discutir os sentidos daquela ocupação em duas direções. Primeiro: fazer uma leitura da pauta de reivindicação e, segundo, tentar conectar aquela mobilização ao contexto mais ampla da vida acadêmica
“Você é feia, feia pra caralho”: um ensaio sobre gênero, beleza e feiura
Authors: Coacci Thiago , Santos Leonel Cardoso dos
Published: April 2018

O presente texto é um ensaio sobre as relações entre as normas de gênero, a beleza e a feiura. Argumentamos que há uma dimensão semiótico-estética na construção dos gêneros, bem como na forma como esses se tornam inteligíveis e consequentemente “passam por naturais”. De forma experimental, realizamos uma pesquisa empírica, com imagens do Google sobre beleza/feiura, em que tentamos identificar padrões e revelar um imaginário social compartilhado sobre beleza e feiura. A partir disso, propomos um resgate do conceito de feiura como útil para uma análise interseccional. Por fim, buscamos identificar algumas possíveis formas de se transformar a realidade e superar as lógicas que produzem hierarquias sociais.
O entre-lugar das trans nas escolas
Authors: Silva Fernando Guimarães Oliveira da , Maio Eliane Rose
Published: April 2018

O presente estudo aponta incursões pela fronteira do in/dizível, da in/visibilidade e da a/normalidade. Classificamos assim porque a questão transgênero, mais que na escola, mas em elevado potencial na sociedade, é cotidianamente marcada por práticas de ódio, discriminação e violência. Movimentado/a pelo desejo de um mundo onde cada pessoa possa avivar a potência identitária de si, objetivamos problematizar a partir do conceito de ‘entre-lugar’ de Homi Bhabha (1998), o deslocamento da heterossexualidade do centro da sexualidade normal para compreender que, em especial na escola como lócus de pesquisa, coexistem diferentes modos identitários de performar o gênero e a sexualidade. Para dar consecução às discussões neste ensaio, nossa pesquisa pautou-se em explorar, utilizando o recurso bibliográfico para compreender como ocorre a articulação entre o “entre-lugar” e a questão das estudantes transgêneros. Como conclusão, acreditamos na escola como um ‘entre-lugar’ que produz deslocamentos significativos por meio de aprendizagens de que somos uma potência viva produzida e negociada numa multiplicidade desconcertante sobre diferentes modos de ser e estar, normativos ou renovados.
A coragem de ser tedioso: aproximações entre dândis e corpos queers
Authors: Duarte Filho Ricardo
Published: April 2018

O presente artigo almeja discorrer sobre a ligação entre o dandismo e os corpos queers através do conceito do camp e da performatividade. Para tal, traça uma ligação histórica entre o dândi e os corpos aristocráticos e argumenta que os dândis formam uma espécie de proto-subjetividade queer através da discussão sobre os julgamentos de Oscar Wilde, vistos aqui como espetáculos midiáticos públicos que acabaram por incutir em esferas diversas, como a judicial, a médica e a pública, a ideia de traços e poses que poderiam se cristalizar como indicadores da existência da homossexualidade. A hipótese aqui levantada é que o dândi, por sua ambígua relação com a norma, possibilita novas formas de resiliência e contestação através da artificialidade, do tédio e da performance. Como forma de discutir sobre essa possibilidade de subversão e também como tentativa de ampliar o emprego de uma sensibilidade dândi e camp para além da cultura anglo-saxã, o objeto analisado no presente artigo é o filme brasileiro contemporâneo A Seita (André Antônio, 2015).

Narrativas corporais do desejo bicha urbano e suas políticas
Authors: Sutherland Juab Pablo
Published: April 2018

Na cidade do desejo ligada às novas tecnologias de comunicação, surgiu uma nova cidade, ao contrário do Hotel Buenaventura, descrito por Jameson em Pós-modernismo: a lógica cultural do capitalismo tardio, cuja arquitetura do espelho devolve à cidade sua própria imagem e onde o hiperespaço pós-moderno conseguiu transpassar o corpo e anular sua mediação; na cidade do corpo existiria uma virtualização com mediações, quer dizer, o desejo como plus-valia do corpo material se intercambia nos cybercafés do centro de Santiago, entretanto, aí a cidade homo se virtualiza como um novo corpo que deixou as ruas do desejo lemebeliano a uma política da representação através da web ou dos aplicativos disponíveis nos dispositivos atuais. A cidade então é mapa virtual, não é o cerro Santa Lucía de La esquina es mi corazón de Lemebel, mas o símbolo de um novo corpo traficado na rede.

Mudanças na imagem corporal de bailarinas que vivenciaram o método BPI
[Graziela E. F. Rodrigues, M. da Consolação G. C. F. Tavares]
Authors: Repertório Teatro & Dança
Published: April 2018

Bailarino-Pesquisador-Intérprete (BPI) é um método coreográfico desenvolvido no Brasil na década de 1980 que prioriza a identidade do bailarino em todo o processo de construção do espetáculo de dança. O objetivo desta pesquisa foi identificar elementos relacionados ao desenvolvimento da imagem corporal a partir da análise dos depoimentos a um conjunto de questões aplicadas a um grupo de pessoas que utilizaram o método BPI no processo de criação. É possível verificar que os três eixos de sustentação do método - Inventário no Corpo, Co-habitar com a Fonte e Incorporação da Personagem - foram identificados por cada pessoa. Existe forte conteúdo emocional vivenciado pela pessoa durante o desenvolvimento do método BPI e isto possibilitou que partes da identidade pessoal, que antes não eram reconhecidas como suas, fossem assumidas e integradas por ela.

The Dancer-Researcher-Performer (DRP) is a choreographic method developed in Brazil during the nineteeneighties, which highlights the dancer's identity during the entire dance performance construction process. The aim of this research was to identify elements related to the development of body image using testimonies to a questionnaires by subjects who have applied the DRP method in creative processes. It is possible to verify that the three axes of method - Body inventory, Co-dwelling with the Source and Character embodiment - were identified by each subject. There is strong emotional content experienced by subject during the development of DRP method and this enabled the dancer's assimilation and integration of parts of his/her identity not hitherto recognized as belonging to himself/herself.
HISTÓRIAS DO AQUI E AGORA: CABARÉ E TEATRALIDADE CIRCENSE
 [Erminia Silva]
Authors: Repertório Teatro & Dança
Published: April 2018

Nos últimos dez anos, no Brasil, grupos de artistas circenses que não possuem ligação específi ca com os circos itinerantes ou de lona, em geral oriundos de escolas de circos, artistas circenses profi ssionalizados ou não, procedentes de diversas áreas das manifestações artísticas (teatro, dança, música, etc.), têm experimentado organizar espetáculos que são denominados de cabaré. A idéia que perpassa essas iniciativas é a de que as apresentações contenham uma diversidade de números artísticos, reunindo, além do próprio grupo ou escola, organizadores do evento, também convidados externos a eles. A partir de um curso de história do circo em uma escola de circo: Cefac – Centro de Formação Profissional em Artes Circenses, foi possível debater com os alunos em sala de aula sobre a história do conceito, dos espetáculos e das casas denominadas cabaré, relacionando-a com as artes circenses. Deste processo, produziu-se este texto descritivo e analítico no sentido de propor um olhar sobre o significado do que seja estudar e pesquisar a história do circo. Tal perspectiva tem como referência a idéia de que vivenciamos um período dessa história, somos herdeiros e protagonistas da mesma. Ou seja, pensar num curso de história não significa só o passado, mas o ir fazendo, aqui e agora.

In Brazil, for the last ten years, circus artists who have no specifi c connection with itinerant or canvas circuses, who usually come from circus schools, either as professional circus artists or not, stemming from diverse areas of the arts (theater, dance, music, etc.), have organized shows known as cabaret. The concept within these initiatives is that presentations contain a diversity of numbers comprising not only the organizing groups or schools, but also a few external, visiting performers. By taking a Circus History course as a starting point at CEFAC, the Professional Circus Art Formation Center, it was possible to promote a classroom discussion on the history of such concept, shows and stages known as cabaret and its relation with circus as an art. The present paper stems from such process as a descriptive and analytical piece of work towards the proposal of an overview on the meaning of studying and researching the history of circus. Such view is referenced upon the idea that we have experienced a period of such history and that we are its heirs and protagonists. This implies that thinking in a history course does not mean the mere thinking of the past, but of the on going present, here and now.
O DRAMA DE CIRCO E O CIRCO-TEATRO HOJE. UMA EXPERIÊNCIA DE REPRESENTAÇÃO DE PAPÉIS COM ARTISTAS CIRCENSES

Published: April 2018

No presente artigo realizo um percurso do contato com as narrativas de experiências vividas pelos artistas circenses que nos leva à reflexão sobre o drama vivido pelas companhias de circo-teatro e sobre a noção de “circo-família”, fazendo uma análise de algumas peças encenadas por estas companhias. Nesse caminho, localizo uma dinâmica de transformação do drama tradicional de circo em comédia e esboço uma compreensão sobre este fenômeno. Para além da análise do drama como texto, refl eto sobre a cena no circoteatro, observando a relação que o palhaço estabelece com a sua platéia. Comento, no final do percurso, a metodologia adotada na proposição da encenação da experiência vivida para a pesquisa etnográfica.

In this article I analyse the story telling about the lived experiences of the circus’actors. I reflect about the drama lived by companies of theater-circus tradition and on the “family circus” idea, doing also an analysis of some plays presented by these studied companies. I try to understand a dynamics of transformation of the traditional drama of circus in comedy which. Besides the analysis of drama as text, I reflect about the scene presented in the theater-circus, observing the relationship between the clown and his audience. In the end, I discuss the methodology adopted to represent their lived experiences to the ethnographic research. 
A Dominação Legitimada do Excluído na Escola e na Sociedade: breve trajetória da subjugação do humano a partir do seu aparte do ambiente natural
Authors: Avila Colla Rodrigo
Published: April 2018

O presente ensaio é uma revisão bibliográfica crítica sobre o tema da dominação do humano pelo humano por meio de um mecanismo de aparte do ambiente natural que vem se constituindo historicamente e culmina numa espécie de naturalização do processo de subjugação/objetificação do outro. É utilizado referencial teórico que mescla autores da área das Ciências Sociais e da Filosofia enfocando aspectos referentes à formação humana. Nesse sentido, são de contribuição importante para as reflexões aqui empreendidas os trabalhos de Humberto Maturana (2002; 2009), Tomaz Tadeu da Silva (1992; 1994) e Leonardo Boff (2009). Parte-se da hipótese de que a perspectiva da ciência e o ideal humanista permeiam a estrutura social que acaba excluindo indivíduos da humanidade (desnaturalizada) para, uma vez quase animalizados, dominá-los (objetificando-os). No texto são analisadas pormenorizadamente as consequências disso na instituição escolar, mas também é feito um panorama de como outras instituições e mecanismos contribuíram historicamente para a dominação do humano. Esse processo de exclusão e domínio, de acordo com o argumento aqui utilizado, se tornam legítimos em virtude da dissociação entre espécie humana e natureza. Assim, uns excluem outros que, excluídos, são legitimamente dominados enquanto “naturais” (portanto objetificáveis) ou “de difícil humanização/socialização”. Ou seja, gradativamente minorando a autonomia da Vida enquanto sistema dinâmico (a objetificando), abrimos – muitas vezes ao querer extingui-las – um leque de oportunidades para a dominação (que se dá, por exemplo, por objetificação) em diversas instâncias e níveis.

Published: April 2018

The AAA ATPase spastin is a microtubule‐severing enzyme that plays important roles in various cellular events including axon regeneration. Herein, we found that the basal ATPase activity of spastin is negatively regulated by spastin concentration. By determining a spastin crystal structure, we demonstrate the necessity of intersubunit interactions between spastin AAA domains. Neutralization of the positive charges in the microtubule‐binding domain (MTBD) of spastin dramatically decreases the ATPase activity at low concentration, although the ATP‐hydrolyzing potential is not affected. These results demonstrate that, in addition to the AAA domain, the MTBD region of spastin is also involved in regulating ATPase activity, making interactions between spastin protomers more complicated than expected.
IFI16 regulates HTLV‐1 replication through promoting HTLV‐1 RTI‐induced innate immune responses

Published: April 2018

Interferon (IFN)‐inducible protein 16 (IFI16) regulates human immunodeficiency virus replication by inducing innate immune responses as a DNA sensor. Human T‐lymphotropic virus type 1 (HTLV‐1), a delta retrovirus family member, has been linked to multiple diseases. Here, we report that IFI16 expression is induced by HTLV‐1 infection or HTLV‐1 reverse transcription intermediate (RTI) ssDNA90 transfection. IFI16 overexpression decreases HTLV‐1 protein expression, whereas IFI16 knockdown increases it. Furthermore, the knockdown of IFI16 is followed by impaired innate immune responses upon HTLV‐1 infection. In addition, IFI16 forms a complex with ssDNA90 and enhances ssDNA90‐triggered innate immune responses. Collectively, our data suggest a critical role for IFI16 during HTLV‐1 infection by interacting with HTLV‐1 RTI ssDNA90 and restricting HTLV‐1 replication.

Published: April 2018

Purpose

The aim of this work is to investigate the effects of immersing EBT3 radiochromic film in water and to evaluate its contribution to the total uncertainty in dose determination.

Materials and methods

We used 3 cm × 3 cm EBT3 radiochromic films irradiated in the range of 0–70 Gy to study the impact of water immersion on the change in net optical density. These films were placed in a water container for a period of 24 h. The net optical density was measured before (0 h) and after of the immersion in water (1, 3, 6, 12, 18, and 24 h). The absorbance spectrum of the EBT3 radiochromic film was measured at 0 h and 24 h after immersion in water. The uncertainty in dose determination due to the effects of keeping the EBT3 radiochromic film submerged in water at 0, 1, and 24 h were recorded in the red, green, and blue channels.

Results

We observed an increase in the net optical density as an effect on the film due to its immersion in water. The penetration of the water at the edges of the radiochromic film was observed to be a function of time during which the film remained in the water. On the other hand, the penetration of water at the edges of the film was found to be independent of irradiation dose.

Conclusions

EBT3 radiochromic film is found more resistant to water penetration through the edges than its predecessors. However, there is evidence that suggest that liquid water damage the Nylon cover layer of the film by changing its optical properties. Therefore, it is recommended to build a new calibration curve for radiochromic films for a specific situation involving dose measurements in liquid water.
Roll‐to‐Roll Fabrication of Solution Processed Electronics
Authors: Abbel Robert , Galagan Yulia , Groen Pim
Published: April 2018

The production of electronic devices using solution based (“wet”) deposition technologies has some decisive technical and commercial advantages compared to competing approaches like vacuum based (“dry”) manufacturing. Particularly, the potential to scale up production processes to large areas and high volumes by introducing continuous roll‐to‐roll (R2R) methods on flexible substrates has been the topic of intense studies from both applied research institutes and industry already for some years. Decisive steps forward have been achieved during that time, resulting in the dawn of commercial applications for a number of processes, while additional development work is still needed in some other fields. This review summarizes the work published during the last few years on the R2R printing and wet coating of electronic devices. An overview is presented of the basic operational principles for the most commonly used R2R printing and coating methods and techniques for proper web handling in R2R lines. Then, the most commonly used types of flexible substrate materials are introduced, followed by a review of the work published in the application areas of transparent conductor materials, printed electric connections, light emitting devices, photovoltaic energy generation, printed logic, and sensing.

Mesoporous silica nanoparticles (MSN) can load and deliver potentially synergistic anticancer agents such as small molecule cytotoxics (like doxorubicin, DOX) and nucleic acids (like microRNA, miRNA). However, these cargos have different underlying chemical properties so overcoming respective intracellular delivery barriers is a key consideration. Strategies to deliver DOX from MSN frequently employ pH‐driven mechanisms that are restricted to the acidic environment of lysosomes. Conversely, strategies to deliver miRNA make use of approaches that deliberately compromise lysosomal membrane integrity to enable cytosolic delivery of the payload. To reconcile these two needs (lysosomal delivery of DOX and intracellular delivery of miRNA), a new methodology by “weaving” polyethylenimine on the MSN surface through disulfide bonds to achieve superior delivery of chemotherapy (DOX) and miRNA therapy (using miRNA‐145) is developed. Furthermore, an active targeting strategy based on a peptide ligand with affinity to glucose‐regulated protein 78 (GRP78), a cell surface protein overexpressed in colorectal carcinoma, is developed. The active targeting approach results in enhanced synergistic antitumor effect both in vitro and in vivo in an orthotopic murine model of colorectal cancer. Taken together, this work demonstrates the capability and advantages of “smart” MSN delivery systems to deliver anticancer cargo appropriately to targeted cancer cells.

Published: April 2018

Stimuli‐responsive energy storage devices have emerged for the fast‐growing popularity of intelligent electronics. However, all previously reported stimuli‐responsive energy storage devices have rather low energy densities (<250 Wh kg–1) and single stimuli‐response, which seriously limit their application scopes in intelligent electronics. Herein, a dual‐stimuli‐responsive sodium‐bromine (Na//Br2) battery featuring ultrahigh energy density, electrochromic effect, and fast thermal response is demonstrated. Remarkably, the fabricated Na//Br2 battery exhibits a large operating voltage of 3.3 V and an energy density up to 760 Wh kg−1, which outperforms those for the state‐of‐the‐art stimuli‐responsive electrochemical energy storage devices. This work offers a promising approach for designing multi‐stimuli‐responsive and high‐energy rechargeable batteries without sacrificing the electrochemical performance.

Published: April 2018

The future of electronics is expected to include healable and wearable devices and systems. To realize this futuristic perspective, several smart conductive materials possessing the characteristics of being healable, flexible, and/or stretchable, are introduced. Silver nanowire (AgNW) healable polymer composite is one of the more promising candidates for this class of material. This ability of AgNW polymer composite to be healable under practical operating conditions is demonstrated. Specifically cracks induced by both mechanical and electrical loading are demonstrated to be healed by thermal treatment. Furthermore, a fatigue test of the AgNW healable conductor is conducted to investigate its mechanical behavior, an important prerequisite for the deployment of new materials. As a proof of concept, a healable touch panel is fabricated to demonstrate its feasibility, laying a stepping stone for future healable electronics.

Published: April 2018

Lithium‐ion batteries (LIBs) have been widely applied in portable electronics (laptops, mobile phones, etc.) as one of the most popular energy storage devices. Currently, much effort has been devoted to exploring alternative high‐capacity anode materials and thus potentially constructing high‐performance LIBs with higher energy/power density. Here, high‐capacity anode nanomaterials based on the diverse types of mechanisms, intercalation/deintercalation mechanism, alloying/dealloying reactions, conversion reaction, and Li metal reaction, are reviewed. Moreover, recent studies in atomic‐scale storage mechanism by utilizing advanced microscopic techniques, such as in situ high‐resolution transmission electron microscopy and other techniques (e.g., spherical aberration‐corrected scanning transmission electron microscopy, cryoelectron microscopy, and 3D imaging techniques), are highlighted. With the in‐depth understanding on the atomic‐scale ion storage/release mechanisms, more guidance is given to researchers for further design and optimization of anode nanomaterials. Finally, some possible challenges and promising future directions for enhancing LIBs' capacity are provided along with the authors personal viewpoints in this research field.

Published: April 2018

Adhesion capabilities of various skin architectures found in nature can generate remarkable physical interactions with their engaged surfaces. Among them, octopus suckers have unique hierarchical structures for reversible adhesion in dry and wet conditions. Here, highly adaptable, biocompatible, and repeatable adhesive patches with unfoldable, 3D microtips in micropillars inspired by the rim and infundibulum of octopus suction cup are presented. The bioinspired synthetic adhesives are fabricated by controlling the meniscus of a liquid precursor in a simple molding process without any hierarchical assemblies or additional surface treatments. Experimental and theoretical studies are investigated upon to increase the effective contact area between unfoldable microtips of devices, and enhance adhesion performances and adaptability on a Si wafer in both dry and underwater conditions (max. 11 N cm−2 in pull‐off strength) as well as on a moist pigskin (max. 14.6 mJ peeling energy). Moreover, the geometry‐controlled microsuckers exhibit high‐repeatability (over 100 cycles) in a pull‐off direction. The adhesive demonstrates stable attachments on a moist, hairy, and rough skin, without any observable chemical residues.

Published: April 2018

A pneumatic nozzle‐based printing technique that can control the crystallization of small molecule organic semiconductor thin films during deposition is reported. By tuning the printing speed and the substrate temperature, large‐sized organic crystals are grown along the printing direction, resulting in field‐effect mobility enhancement by 50 times compared to spin‐coated films for 6,13‐bis(triisopropylsilylethynyl)‐pentacene. Furthermore, silver electrodes using the technique to fabricate printed flexible inverters with a gain as high as 16 are printed.

Atomically engineered oxide heterostructures provide a fertile ground for creating novel states, for example, a 2D electron gas at the interface between two oxide insulators, giant thermoelectric Seebeck coefficient, emergent ferromagnetism from otherwise nonmagnetic components, and colossal ionic conductivity. Extensive research efforts reveal that oxygen deficiency or lattice strain play an important role in determining these unexpected properties. Herein, by studying the abrupt presence of robust ferromagnetism (up to 1.5 µB/Mn) in LaMnO3‐based heterostructures, the multivalence states of Mn that play a decisive role in the emergence of ferromagnetism in the otherwise antiferromagnetic LaMnO3 thin films are found. Combining spatially resolved electron energy‐loss spectroscopy, X‐ray absorption spectroscopy, and X‐ray magnetic circular dichroism techniques, it is determined unambiguously that the ferromagnetism results from a conventional Mn3+‐O‐Mn4+ double‐exchange mechanism rather than an interfacial effect. In contrast, the magnetic dead layer of 5 unit cell in proximity to the interface is found to be accompanied with the accumulation of Mn2+ induced by electronic reconstruction. These findings provide a hitherto‐unexplored multivalence state of Mn on the emergent magnetism in undoped manganite epitaxial thin films, such as LaMnO3 and BiMnO3, and shed new light on all‐oxide spintronic devices.

The important synaptic functionalities, such as long‐term memory, short‐term memory, and experience‐dependent learning, are extensively emulated by the emerging memristive devices, which provide a main step toward brain inspired computing. The majority of the electronic synapses based on memristors usually focus on the emulation of the physiological behaviors at the cellular level. However, the research on the subcellular synaptic dynamic properties of electronic synapses is rarely reported. In this article, Ag/Ta2O5/Pt‐based memristors are utilized to emulate both the long‐term memory and short‐term facilitation of biological synapse. Under pulse‐train measurements, the device exhibits short‐term facilitation depending on varying the electrical pulse intensity, duration, and frequency. Based on the experimental results, one‐to‐one correspondence is established between the filament dynamics in our device and the subcellular synaptic dynamics during short‐term facilitation. By fitting the experimental results into the biological model, the dynamic displacements of the rear and head ends of the Ag filament are drawn analogy to the neurotransmitter and Ca2+ dynamics. The dynamic process is explained by simulations of the nanoparticle dynamics in which the Ag filament is simplified to a 1D “stick.” This research enables the emulation of synaptic function with improved biofidelity and broad applications to neuromorphic computing.

Dispersion interactions can play an important role in understanding unusual binding behaviors. This is illustrated by a systematic study of the structural preferences of diphenyl ether (DPE)–alcohol aggregates, for which OH⋅⋅⋅O‐bound or OH⋅⋅⋅π‐bound isomers can be formed. The investigation was performed through a multi‐spectroscopic approach including IR/UV and microwave methods, combined with a detailed theoretical analysis. The resulting solvent‐size‐dependent trend for the structural preference turns out to be counter‐intuitive: the hydrogen‐bonded OH⋅⋅⋅O structures become more stable for larger alcohols, which are expected to be stronger dispersion energy donors and thus should prefer an OH⋅⋅⋅π arrangement. Dispersion interactions in combination with the twisting of the ether upon solvent aggregation are key for understanding this preference.

The thin adhesive film with tunable interfacial adhesion can be applied in a broad range of display applications, from optically clear films to flexible devices. We have fabricated adhesive films including evaporable polymeric nanocapsules which can form thermally induced bubble gaps at the interface. These nanocapsules consisted of a poly(methyl methacrylate) core and a polyethyleneimine shell, and were impregnated with methylcyclohexane as a vaporization material. The evaporated core materials facilitated the desorption of thin adhesive film through bubble formation on the adhesive interface after thermal treatment, resulting in improved detachment of the adhesive layer. The optimization of the bubble gaps was performed to adjust the adhesive strength by varying the duration and temperature of thermal treatment, as well as the quenching temperature. The evaporable adhesive film with nanocapsule concentration of 1.0 wt % resulted in high transmittance of 94.9%, with the best adhesive strength reduction of 57.6% obtained after thermal treatment. © 2018 Wiley Periodicals, Inc.

Factors influencing resorcinol–formaldehyde–latex‐coated continuous basalt fiber cord/rubber interfacial fatigue behavior: Loading direction and RFL formula
Authors: Wan Jijun , Li Zhuo , Yang Yihan , Zhao Shugao
Published: April 2018

In this study, samples were prepared with resorcinol–formaldehyde–latex (RFL)‐coated continuous basalt fiber (CBF) cords and a natural rubber (NR)/styrene–butadiene rubber (SBR) matrix for interfacial fatigue tests under periodic radial loading conducted using a De Mattia Rubber Flexometer. The effects of the RFL formula on the interfacial fatigue behavior, including the fatigue life and the evolution of residual adhesion strength, were the focus of this work. The fatigue behavior was compared with that under axial loading. The results showed that under radial loading, the residual adhesion strength of the samples remained higher than that under axial loading, and the evolution of adhesion was divided into three stages. The adhesion improvement in the second stage was due to further cocrosslinking between the rubber matrix and the latex in the RFL layer, and the duration of the second stage was determined by the amount of reactive latex in the RFL layer. © 2018 Wiley Periodicals, Inc.

France and the Blue Pacific
Authors: Maclellan Nic
Published: April 2018

Under the concept of the ‘Blue Pacific’, island nations are placing increased priority on the oceans, seeking to integrate policy on climate change, maritime security, fisheries and ocean biodiversity. This agenda however affects France, one of the remaining colonial powers in the Pacific, which controls a vast maritime domain in the region. The 2016 decision to incorporate the French dependencies New Caledonia and French Polynesia as full members of the Pacific Islands Forum raises a series of diplomatic challenges for Forum island countries. This article outlines France's interest in the Blue Pacific, in areas such as exclusive economic zones, security, research, climate and maritime boundaries. It then details problems facing Forum member countries arising from France's ongoing control of its three dependencies in the region, including uncertainty over legal standing in the Forum; the capacity to sign treaties; policy making on security in the Forum; policy issues on fisheries and climate in other member agencies of the Council of Regional Organisations of the Pacific; relations with other Forum dialogue partners; resource exploitation by the colonial power; and disputes over maritime boundaries.

Vascular endothelial growth factor (VEGF) represents one of the main factors involved not only in angiogenesis and vasculogenesis but also in neuritogenesis. VEGF plays its function acting via different receptors: VEGF receptor1 (VEGFR‐1), VEGF receptor2 (VEGFR‐2), VEGF receptor3 (VEGFR‐3), and co‐receptors Neuropilin‐1 (NRP1) and Neuropilin‐2 (NRP2). This study reports on the first in vivo analysis of the expression of VEGF and VEGF family molecules in peripheral nerve degeneration and regeneration: for this purpose, different models of nerve lesion in rat were adopted, the median nerve crush injury and the median nerve transaction followed or not by end‐to end microsurgical repair. Results obtained by real time polymerase chain reaction showed that VEGF and VEGF family molecules are differentially expressed under regenerating and degenerating condition, furthermore, in order to study the modulation and involvement of these factors in two different regenerative models, crush injury and end‐to‐end repair, protein expression analysis was evaluated. In addition, immunohistochemical analysis allowed to state a glial localization of VEGF and VEGFR‐2 after peripheral nerve crush injury. Finally in vitro assay on primary Schwann cells culture show that VEGF165 stimulation increases Schwann cells migration, a major process in the promotion of neurite outgrowth.

Published: April 2018

Low‐energy pulsed electromagnetic field (PEMF) therapy has been suggested as a promising therapy to increase microcirculation, which is of great concern in patients with fibromyalgia. This study evaluated the effectiveness of PEMF therapy on the treatment of fibromyalgia. A group of 108 women with fibromyalgia were allocated to a 12‐week treatment period with an active Bio‐Electro‐Magnetic‐Energy‐Regulation (BEMER) device and a similar treatment period with an inactive device. Each patient received active and sham treatments in a random order. Pain and stiffness were assessed on a visual analog scale (VAS, scale 0–100 mm), and functional status was assessed by the Fibromyalgia Impact Questionnaire (FIQ). Mean VAS pain scores before the active and sham treatment periods were 66 (SD 22) and 63 (SD 22), respectively. After treatment periods, mean VAS pain scores had decreased significantly in active treatment, −12, 95% CI [−18, −6], and in sham treatment, −11, 95% CI [−17, −5]. Similarly, the decrease in stiffness and FIQ index after both treatments was statistically significant. However, per‐protocol analysis showed no differences between active and sham treatments at any of the outcomes. This study demonstrated that low‐energy PEMF therapy was not efficient in reducing pain and stiffness or in improving functioning in women with fibromyalgia.

Published: April 2018

This research presents the results of the teaching innovation Dynamic Online Assessment System in Mathematics, which is implemented in higher education to promote self‐study by students outside the classroom. The WIRIS calculator was integrated into the Moodle platform to create questions with random elements, for example, students had access to different variants of the same question. The effect of the type of feedback (immediate or deferred) on the work of the students on the platform, measured by means of participation, time spent, and grades obtained, was evaluated. We used a quasi‐experimental methodology for a population of 5,507 students, distributed in 229 courses on four campuses that learn Mathematics I in engineering programs. Immediate feedback exhibits better work of students on the platform, but this work is not necessarily more efficient in comparison with the work performed by students using assessments online assessment with deferred feedback.

Published: April 2018

Computer Programming Languages are various languages used for developing a sequence of instructions and/or proofing errors, which language designers often overlook. Consequently, with the degree of fast moving life and improving technology, programming packages have been increasing. Choosing an appropriate language is a complex task and also many factors must be considered. While selecting educational software and its technical characteristics, reducing the time and effort needed in the learning process have to be considered. Evaluation of CPLs are inevitable in decision making. Multi‐criteria decision making helps for evaluating and comparing alternatives with respect to criteria. Therefore, in this article the fundamental attributes of programming languages, utilizing and steps of the TOPSIS are discussed. For evaluating the performance of some traditional CPLs in higher education on regarding seven criteria, we have constructed a function in Mathematica (a scientific computing package) that implements the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), a well‐known multi‐criteria decision method. Also, another contribution of this study is comparing TOPSIS methods results with AHP methods results.
