Placement and Anchoring of Trigeminal Neurostimulation Electrodes: Technical Report
Authors: Kasoff Willard S. , Bina Robert W.
Published: January 2020

Background: Peripheral neurostimulation (PNS) for medically refractory trigeminal and craniofacial pain is an emerging alternative to traditional surgical approaches. Technical problems with craniofacial PNS have included electrode migration and erosion, limiting the utility and cost-effectiveness of this procedure. Objective: To review our institutional surgical technique for trigeminal PNS implantation, focusing on a novel technique for electrode anchoring. Methods: Consecutive cases of permanent craniofacial PNS placement by a single surgeon over 36 months were reviewed for surgical technique and technical outcomes. Electrodes were placed percutaneously with open anchoring to the pericranium at a separate parietal incision. Results: Sixteen systems (53 electrodes) were implanted in 14 patients. Median follow-up was 13 months (range, 5–29 months). Electrode placement was successful in all cases with no intraoperative complications. There was 1 lead migration (6.3% per patient; 1.8% per lead) and no cases of erosion. Two patients (14.3%) required explant for infection, 1 of whom was successfully reimplanted. Three patients (21.4%) underwent surgical revision other than for infection. Conclusions: We present an improved method for craniofacial PNS surgery which introduces a separate incision for electrode anchoring at the parietal boss. This technique simplifies the procedure and greatly reduces rates of erosion and migration, improving patient comfort and satisfaction.

Published: January 2020

Over a period of 1 year, a 74-year-old man slowly developed a painless left upper eyelid intratarsal mass. The skin was movable over the lesion. At surgery, a well-circumscribed, yellow-white, partially cystic tumor was encountered. Histopathologically it was composed of a random mixture of basaloid and sebaceous cells arranged in interconnecting cords. Immunohistochemical evaluation disclosed epithelial membrane antigen, adipophilin, and cytokeratin 14 positivity. These findings led to the diagnosis of a sebaceoma. The tumor cells abnormally failed to express mismatch repair proteins for MLH1 and PMS2. The patient did not have a personal history of any visceral malignancy, but his father had died at the age of 46 years and a daughter at the age of 33 years from colonic carcinomas. The implications of this periocular sebaceoma for the Muir-Torre syndrome are explored.

Published: January 2020

Introduction: The CAIDE (Cardiovascular Risk Factors, Aging, and Incidence of Dementia) dementia risk score is based on demographic, genetic, and modifiable risk factors in midlife and has been shown to be predictive of later-life dementia. Objective: To test the predictive capacity of the CAIDE dementia risk score among a cohort of Japanese-American men. Methods: Midlife measures were obtained from a sample of 3,582 Japanese-American men in the Honolulu Heart Program (1965–1968, average age = 53.1 years). A follow-up exam in 1991 (average age = 77.8 years) assessed cognitive impairment using the Cognitive Abilities Screening Instrument (CASI). Severe cognitive impairment was defined as a CASI score <60. Results: In this cohort, the CAIDE dementia risk score demonstrates significant association with later-life severe cognitive impairment (OR = 1.477, 95% CI: 1.39–1.58). However, the area under the receiver-operating characteristic curve c-statistics suggests poor predictive ability (c = 0.645, 95% CI: 0.62–0.67). Using a score cut-point of 10, the accuracy is acceptable (0.82), but the sensitivity is low (0.50). Conclusion: While the CAIDE dementia risk score at midlife is associated with later development of cognitive impairment in Japanese-American men, its predictive capacity in this population is weak.
Electrophysiological Responsiveness to Long-Term Therapy in Chronic Inflammatory Demyelinating Polyneuropathy: Case Report
Authors: Khomand Payam , Katzberg Hans , Ngo Mylan , Bril Vera
Published: January 2020

Electrophysiological studies are essential for the diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP), but the utility of nerve conduction studies in monitoring outcomes in individual CIDP patients is controversial. Electrophysiological improvements after short-term treatment have been described in large cohorts of CIDP patients, but the magnitude of the changes is small and might be obscured in individual patients due to the variation inherent in nerve conduction testing. We present the case of a CIDP patient treated successfully with immunosuppression and followed for 31 years with serial standardized clinical and electrophysiological evaluations. Improvement in electrophysiological parameters lagged clinical changes for up to 2 years, but all motor parameters improved (distal motor and F wave latencies, conduction velocities, and compound muscle action potential amplitudes) even with evidence of initial axonal damage. Worsening of electrophysiological parameters, specifically increasing F wave latencies, heralded clinical relapse by as much as a year. Electrophysiological parameters do improve with treatment in CIDP patients, although the changes can take up to 2 years, and also worsening electrophysiological parameters can herald clinical relapse and might help guide therapeutic decisions.
Calcium-Alkali Syndrome Associated with Hypoparathyroidism Following Total Thyroidectomy
Authors: Kuroya Sayaka , Yazawa Masahiko , Shibagaki Yugo , Tominaga Naoto
Published: January 2020

Background: Patients with permanent postsurgical hypoparathyroidism, a complication of total thyroidectomy, often require high calcium supplementation with vitamin D to maintain serum calcium levels. The epidemiology of calcium-alkali syndrome (CAS) in patients with hypoparathyroidism after total thyroidectomy remains unclear. This study aimed to investigate the incidence of hypercalcemia, renal impairment, metabolic alkalosis, and CAS in patients treated for presumed hypoparathyroidism after total thyroidectomy. Methods: Twenty-seven patients with neck cancers who underwent total thyroidectomy without parathyroid autotransplantation between January 2010 and October 2013 at our hospital were consecutively included. All patients received calcium lactate and alfacalcidol for postsurgical hypocalcemia. We defined hypercalcemia as a corrected serum calcium level (cCa) ≥10.5 mg/dL, metabolic alkalosis as a difference in serum sodium and serum chloride ([sNa-sCl]) ≥39 mEq/L, and renal impairment as a ≥50% increase in serum creatine and/or ≥35% decrease in estimated glomerular filtration rate (eGFR) compared to baseline. Results: cCa peaked (11.1 ± 1.5 mg/dL) at a median of 326 days (interquartile range 78–869) after surgery. At peak cCa, [sNa-sCl] was significantly higher (p < 0.01), and eGFR was significantly lower (p < 0.01) than that at baseline. Fifteen patients (55.6%) had hypercalcemia, 19 (70.3%) had alkalosis, 12 (44.4%) had renal impairment, and 9 (33.3%) had CAS. Patients with CAS (mean age 67.1 ± 10.8 years) were older than those without CAS (56.7 ± 13.6 years, p = 0.06). The mean dose of alfacalcidol in the CAS group (3.1 ± 1.2 μg/day) was significantly larger than that in the non-CAS group (2.1 ± 1.0 μg/day, p = 0.03). Conclusions: This retrospective study reveals the high incidence of CAS in patients with hypoparathyroidism after total thyroidectomy. Furthermore, these findings suggest that the serum calcium level, acid-base balance, and renal function should be closely monitored in patients with postsurgical hypoparathyroidism who receive large doses of active vitamin D.
What We Can Find Beyond the Classic Neuroimaging Findings of Congenital Zika Virus Syndrome?
Authors: Niemeyer Bruno , Hollanda Rafael , Muniz Bernardo , Marchiori Edson
Published: January 2020

Background: In 1947, Zika virus (ZIKV) was first discovered in Monkeys, in Zika Forest, in Uganda, Africa. Five years later, (1952) the first human Zika infection was detected in Nigeria, Africa. After this date, only sporadic cases happened, until the first 3 epidemics occurred, all outside Africa. The first epidemic was in Yap Island in 2007, the second in French Polynesia in 2013, and the third in 2015 in the northeast of Brazil, and then the spread to the Americas in 2015 and 2016. However, it was only after the epidemic in the northeast of Brazil, in the first half of 2015, that many babies were born with microcephaly in the second semester of that same year and in 2016. Until now, every year, some babies are still born with congenital ZIKV syndrome (CZVS). Summary: The objective of this article is to describe infrequent and rarely discussed imaging (computed tomography and magnetic resonance imaging) findings of CZVS, in addition to those classically described such as a simplified gyral pattern, ventriculomegaly, corpus callosum dysgenesis, craniofacial disproportion, and redundant scalp, thus suggesting an increase in the spectrum of neurological findings related to the syndrome.
Modelagem geométrica no inventário dos bens patrimoniais
Authors: Bononi Wanda Terezinha , Silva Ricardo Dias
Published: January 2020

Considerando que os bens patrimoniais são o suporte da memória e podem ser capazes de consolidar ou de construir a identidade de uma sociedade, este artigo tem por objetivo apresentar o inventário 3D da capela Imaculada Conceição, localizada no município de Cruzeiro do Oeste - PR, construção testemunha do período da expansão colonial no território paranaense e representante da cultura daquela sociedade e de sua técnica construtiva singular de construções dos templos religiosos na região.  Para tanto, foi preciso desenvolver um protocolo de inventário para edifícios religiosos construídos em madeira, visto que os modelos existentes não atendem, de forma satisfatória, às especificidades desses bens, que necessitam de reparação e substituição de suas peças. A modelagem geométrica tem a capacidade de representar e analisar objetos históricos, produzindo réplicas digitais que possibilitam registro e gerenciamento do patrimônio histórico mais preciso, tornando-se uma ferramenta fundamental para o processo de documentação e valorização do bem.

Published: January 2020

A estruturação do Projeto Santa Leopoldina_Digital (SL_Digital) se apresenta como continuidade e ampliação de perspectivas abertas por investigações vinculadas ao Laboratório Patrimônio & Desenvolvimento, da Universidade Federal do Espírito Santo. São trabalhos com objetivos de documentar e representar o patrimônio territorial, orientados à elaboração de subsídio metodológico para projeto, planejamento e intervenção. Em perspectiva conceitual, o registro de elementos patrimoniais se orienta para o mapeamento de objetos e ações com potencial para sustentar a interpretação do patrimônio territorial e prospecção de cenários e projetos de transformação patrimonial. Insere-se na reflexão sobre o estado da arte contemporâneo referente à problemática da insustentabilidade no território e à superação dos pares dicotômicos patrimônio-sagrado e desenvolvimento-destruição. Santa Leopoldina é o núcleo urbano mais antigo do Espírito Santo e um dos primeiros a se instalar nas terras não costeiras. A essa condição histórica soma-se seu valor como lugar do encontro multicultural e social. Realização no tempo, é compreendida em sua dimensão arquitetônica e urbanística, por meio da identificação de unidades espaciais de expansão urbana. O registro do patrimônio territorial-paisagístico e a interpretação de processos com impacto em sua conservação permitem avaliar a mudança da ambiência urbana em sua associação com o mapeamento de valores. SL_Digital se apresenta como instrumento de representação, planejamento e gestão, contribuindo para o reconhecimento, a preservação e a (re)inserção de valores no território.
A Tradição na Produção de Estatuetas Cicládicas (3.200-2.700 a.C.)
Authors: Sabadini Francisco De Assis
Published: January 2020

As ilhas localizadas a sudeste do mar Egeu, denominadas Cíclades, foram palco para o florescimento de diferentes culturas durante o período do Bronze Antigo (3.200 a 2.000 a.C.). Entre 2700-2300 a.C., uma cultura denominada Keros-Siros produziu inúmeros exemplares de estatuetas padronizadas estilisticamente, conhecidas como estatuetas do tipo canônica ou braços cruzados. A despeito da forte manutenção de elementos tradicionais na produção dessas peças, a existência de variações estilísticas não é incomum. O presente artigo revisa e busca identificar os principais traços estilísticos, bem como as variações existentes nas estatuetas produzidas pela cultura Keros-Siros.
Vegetarianismo en la Grecia Antigua
Authors: Bernabé Alberto
Published: January 2020

En Grecia existieron formas de vegetarianismo, pero nunca fueron opciones simplemente dietéticas, sino que obedecían a principios filosóficos o religiosos. Se estudian las propuestas de los órficos, los pitagóricos y Empédocles, señalando las analogías y diferencias entre ellas. Todos comparten la creencia en la transmigración de las almas, pero mientras para los órficos y Empédocles la transmigración es un castigo por un pecado relacionado con el derramamiento de sangre, para los pitagóricos parece ser una mera condición para el mantenimiento de la vida en el universo. Por otra parte, mientras para los pitagóricos y Empédocles el vegetarianismo parece ser consecuente con la idea de que el alma puede transmigrar a animales y, por tanto, postulan una solidaridad entre todos los seres animados, parece que los órficos solo muy tarde postulan la transmigración de almas entre seres humanos y animales, por lo que el motivo fundamental de la abstención de carne es evitar el derramamiento de sangre. Asimismo se examina el uso político que los atenienses hacen del mito de la introducción del cultivo cereal por obra de Deméter.
Pirataria e Comércio de Escravos em Ação na Grécia Clássica e Helenística
Authors: Lewis David Martin
Published: January 2020

A maioria dos escravos no mundo grego eram não-gregos importados e seus descendentes. Ainda assim, sabemos pouco sobre a inserção de indivíduos da periferia não-grega na escravidão. Muito mais promissor para o estudo dessa inserção na escravidão é um processo numericamente menos significativo: a pirataria, onde a captura e venda de indivíduos – principalmente gregos – é extensivamente documentada. A pirataria era tanto uma forma de trabalho em si mesma quanto um meio de se conseguir trabalho. O objetivo desse artigo é explorar, por meio do estudo do trabalho da tripulação pirata, da tecnologia à sua disposição e do destino de suas vítimas, os aspectos pragmáticos de captura e venda, bem como o nível em que a prática de resgatar prisioneiros impedia cativos de comporem o suprimento de escravos.
Trabalho Rural Assalariado no Mediterrâneo Antigo
Authors: Knust José Ernesto Moura
Published: January 2020

Economias pré-capitalistas não possuem amplos e livres mercados de trabalho livre. A realidade econômica do Mediterrâneo Antigo não era uma exceção. Em seu mundo rural, sobretudo, o peso das economias camponesa e escravista diminuía ainda mais o espaço para o livre mercado de trabalho livre. Contudo, os textos antigos mostram inúmeros exemplos de trabalho assalariado. Identificar como se organizava esse trabalho rural assalariado e explicar sua dinâmica dentro de uma realidade pré-capitalista são os objetivos deste artigo. Tendo como fonte primária central o tratado sobre agricultura de Catão, mas buscando informações em outras fontes antigas de diferentes regiões do Mediterrâneo, apresentarei um quadro básico de situações e formas em que o trabalho assalariado aparece no campo. Por fim, identificarei nas relações sociais diversas estabelecidas com a vizinhança o elemento estruturante dessas relações mercantis de trabalho assalariado.
Piracy and Slave Trading in Action in Classical and Hellenistic Greece
Authors: Lewis David Martin
Published: January 2020

Most slaves in the Greek world were imported non-Greeks and their offspring. Yet little is known of the entry into slavery of individuals from the non-Greek periphery. Far more promising for studying entry into slavery is a less numerically significant process, piracy, where the capture and sale of individuals – mainly Greeks - is extensively documented. Piracy was both a form of labour in itself, and a means of acquiring labour. The aim of this article is to explore the pragmatic aspects of capture and sale, as well as the extent to which the practice of ransoming prisoners kept captives away from entering the slave supply, by studying the pirate crew’s work, the technology at its disposal, and the fate of its victims.

Authors: Cunha Mila González da
Published: January 2020

O presente trabalho parte de colocações integradas pelos verbos de cambio hacerse, ponerse e volverse, identificadas em um corpus do espanhol através de programa de computador. Os dados obtidos são, então, descritos por meio das funções léxicas.As funções léxicas constituem uma linguagem formal criada no âmbito da Teoria Sentido-Texto para descrever de maneira sistemática todos os tipos de relações léxicas entre as unidades léxicas de qualquer língua (MEL’ČUK, 1996, p. 38). Com as funções léxicas se espera fornecer para qualquer unidade léxica todas as demais unidades léxicas a ela relacionadas de modo a suprir as necessidades do falante nas suas escolhas lexicamente direcionadas, dentre elas as colocações.Esse processo é inspirado na proposta de Thierry Fontanelle (1998), que parte de colocações identificadas através de critérios de frequência, para, então, descrevê-las utilizando-se do aparato teórico das funções léxicas.

A Perturbadora presença animal: a "Representação" do outro da nossa cultura , em "Volamos" de Antonio Di Benedetto
Authors: Francini Ana Carolina Macena
Published: January 2020

Em As palavras e as coisas, Michel Foucault tece reflexões sobre a “mesmidade”, uniformidade, do pensamento ocidental, ordenado pela linguagem, ou melhor, por suas ruínas. Entretanto é interessante notar que é a partir da perturbação causada pelo conto fantástico “O idioma analítico de John Wilkins”, de Jorge Luis Borges, que Foucault inicia sua trajetória de perscrutar as ruínas da linguagem que outrora deram sustentação ao conhecimento e suas taxonomias, desdobrando-se numa discussão inerente à modernidade sobre a capacidade da linguagem de nomear as coisas e os seres viventes do mundo ao confiná-los em categorias. Para o filósofo francês, "uma certa enciclopédia chinesa", citada no relato de Borges, causa riso e perturbação, já que a tentativa de classificação dos animais por meio da ordem alfabética delata as limitações do pensamento racional de abarcar o ‘outro’ e remete ao impensável, à desordem e ao caos. Por sua vez, o intento de classificação no conto borgiano, na verdade, interpela exatamente sobre a impossibilidade dessa ordenação por meio da linguagem, do discurso racional, que somente pode fazê-la forjando categorias. Daí seja possível pensar o discurso literário - neste caso, o conto fantástico- como espaço privilegiado para sondar o “outro” de nossa cultura, ao “escavar” a linguagem, descentralizando os sentidos e desestabilizando o sistema de categorias, como faz o texto de Borges. Este também será o percurso deste trabalho que apresenta um estudo do conto "Volamos", presente no livro Mundo Animal (1953), do argentino Antonio Di Benedetto, publicado no pós-guerra, período em que as concepções dominantes sobre o humano entram em crise e nota-se um inegável interesse em problematizar os conceitos sobre humanidade e animalidade, por meio da ficção. A análise desse conto, considerado pertencente ao modo fantástico da literatura, indaga sobre como o sentimento perturbador que caracteriza esse estilo pode surgir da (estranha e ao mesmo tempo familiar) presença animal, uma presença não totalmente ‘pensável’ pela racionalidade humana confinada no Mesmo, porém repleta de sentido.
Rayuela no horizonte do não interpretável
Authors: Silva Amanda Luzia da
Published: January 2020

Desde os anos sessenta, o romance Rayuela (1963), de Julio Cortázar, foi lido muitas maneiras diferentes. Assistimos, durante os primeiros anos após a sua publicação, a uma série de leituras e análises elogiosas dedicadas ao livro, porém, anos mais tarde, o cenário se transforma e o que antes era celebrado como renovação e ruptura estética passa a ser considerado como ultrapassado. O texto incomoda e, para muitos de seus antigos leitores, a impressão que fica é de que se tenha tornado o livro ilegível. Por isso, propomos, neste trabalho, uma releitura de Rayuela tomando como eixo condutor justamente aquilo que, ao nosso ver, parece ser a causa desse incômodo, isto é, aquilo que escapa à interpretação.
A cidade moderna na visão de Roberto Arlt
Authors: Santana Bruno Cruz
Published: January 2020

Este trabalho tem como objetivo estudar as visões da cidade moderna que se desdobram nas crônicas e nos contos de Roberto Arlt, produzidos entre os anos 1920 e 1930. Nestes textos está em foco a cidade de Buenos Aires, num período de intensas transformações políticas, econômicas e sociais provocadas pelos processos de modernização. O estudo das imagens deste novo espaço significa pensar as vanguardas latino-americanas como movimento artístico, embora heterogêneo, definido desde um lugar-comum, a cidade moderna.

Para isso, este estudo focalizará a relação entre crônica e conto, indicadora de uma mescla discursiva moderna que responde aos processos de modernização nos centros urbanos e de legitimação da literatura. A partir disto, voltamos à pergunta sobre a escrita literária no exercício de uma escrita híbrida e flexível que é a crônica moderna, especialmente, o importante papel da crônica na observação das novas experiências urbanas, num processo onde literatura e jornal se inter-relacionam na tentativa de representar a cidade.
Historiadores como metateatro na dramaturgia de Rodolfo Usigli
Authors: Hasmann Robson Batista dos Santos
Published: January 2020

A aproximação entre a história e a ficção proporciona um campo bastante fértil nos estudos sobre a América Latina. O crítico Roberto González Echevarría (2000), por exemplo, procurou demonstrar que a ficção romanesca é credora de uma série de discursos jurídicos e legais produzidos nos primeiras décadas da colonização. Da mesma forma, André Trouche (2006) buscou evidenciar que a reflexão e a reescrita da história é uma constante da produção ficcional. Mais recentemente, Leyla Perrone-Moisés (2007) destacou que boa parte dos “paradoxos do nacionalismo” da América Latina é entrevisto no trabalho dos ficcionistas com a historiografia do continente. Porém, a dramaturgia não faz parte desses estudos e raramente aparece em outros que se dedicam a trabalhar essa perspectiva teórica na literatura hispano-americana. Com efeito, nosso trabalho propõe inserir o texto teatral nesse espectro de abordagens. . Selecionamos duas peças mexicanas do dramaturgo Rodolfo Usigli, a saber El gesticulador (1938) e Corona de sombra (1943). Usigli é considerado o principal responsável pela revitalização da arte dramática em seu país, em particularporque construiu sua obra a partir do conceito de que ele chamou de “anti-historia”. Nas obras selecionadas, destaca-se a figura de historiadores como personagens centrais. Buscamos centrar nossa leitura em uma possível função “metateatral” dessas personagens.

Published: January 2020

Este artigo é resultante da comunicação “Lembrança e amizade: o compartilhar da memória em Glosa, de Juan José Saer”, projeto de pesquisa apresentado na IV Jornada do Programa de pós-graduação em língua espanhola e literaturas espanhola e hispano-americana, em 2015. Em Glosa (1985), romance do escritor argentinoJuan José Saer (1937-2005), as relações privilegiadas entre os personagens não são as familiares ou as românticas, mas as de amizade. Neste projeto de pesquisa, pretende-se analisar os modos e efeitos do exercício da memória compartilhada nesse romance. Os pontos de vista de um grupo de amigos compõem versões das lembranças de uma celebração, desde o relato dos protagonistas que não estiveram presentes até as versões dos participantes do evento. Sendo assim, a rede de amigos que se encontra para conversar e discutir é o tecido básico sobre o qual as histórias se tramam. A partir disso, propõe-se a análise das possibilidades e limites do relato de uma memória comum contribuir para o estabelecimento e manutenção de relações de amizade na narrativa.

Linguagem e escuta nas Aguafuertes Cariocas
Authors: Santos Andreia Moura dos
Published: January 2020

Nas próximas linhas nos propomos a analisar no livro de crônicas de Roberto Arlt Aguafuertes Cariocas, escritas em 1929 na ocasião de sua visita ao Brasil, a aparição do português, seja em sua forma escrita, seja em forma de escuta. Para tanto, pretendemos verificar nas crônicas como Arlt se apropria e escuta a língua do outro, com o objetivo de averigar de que forma o português se insere na já questionada linguagem arltiana. Buscaremos identificar como e quando o português é a opção do cronista, afim de explicitar o uso territorial que ele faz do idioma além de ponderar sobre a forma como ele se apropria da língua do outro. Também será nosso interesse analisar a forma como Arlt escuta o português: a quem lhe interessava escutar e de que forma.  Dessa maneira tentaremos descobrir que tipo de atenção o cronista dá a voz do outro.
Deconstructing Reorienting of Attention: Cue Predictiveness Modulates the Inhibition of the No-target Side and the Hemispheric Distribution of the P1 Response to Invalid Targets

Published: January 2020

Orienting of attention produces a “sensory gain” in the processing of visual targets at attended locations and an increase in the amplitude of target-related P1 and N1 ERPs. P1 marks gain reduction at unattended locations; N1 marks gain enhancement at attended ones. Lateral targets that are preceded by valid cues also evoke a larger P1 over the hemisphere contralateral to the no-target side, which reflects inhibition of this side of space [Slagter, H. A., Prinssen, S., Reteig, L. C., & Mazaheri, A. Facilitation and inhibition in attention: Functional dissociation of pre-stimulus alpha activity, P1, and N1 components. Neuroimage, 125, 25–35, 2016]. To clarify the relationships among cue predictiveness, sensory gain, and the inhibitory P1 response, we compared cue- and target-related ERPs among valid, neutral, and invalid trials with predictive (80% valid/20% invalid) or nonpredictive (50% valid/50% invalid) directional cues. Preparatory facilitation over the visual cortex contralateral to the cued side of space (lateral directing attention positivity component) was reduced during nonpredictive cueing. With predictive cues, the target-related inhibitory P1 was larger over the hemisphere contralateral to the no-target side not only in response to valid but also in response to neutral and invalid targets: This result highlights a default inhibitory hemispheric asymmetry that is independent from cued orienting of attention. With nonpredictive cues, valid targets reduced the amplitude of the inhibitory P1 over the hemisphere contralateral to the no-target side whereas invalid targets enhanced the amplitude of the same inhibitory component. Enhanced inhibition was matched with speeded reorienting to invalid targets and drop in attentional costs. These findings show that reorienting of attention is modulated by the combination of cue-related facilitatory and target-related inhibitory activity.

The tribe Xylenini Guenée, is especially rich in the Himalayan region with the highest diversity occurring during the late fall and winter. Exploration of this fauna has a rich history but became especially intensive during recent decades resulting in many new descriptions. Milestones in this vast territorial study by country include Pakistan (Ronkay & Ronkay 1999), India (Hacker 1992), Nepal (Hreblay & Ronkay 1998, Benedek et al. 2013), Taiwan (Hreblay & Ronkay 1997; 2000, Ronkay & Ronkay 2000) Thailand, Vietnam (Hreblay et al. 1999) and China (Ronkay et al. 2010, Benedek et al. 2012; 2013). To this list we now add the mountainous areas of Myanmar which have only recently become accessible. During a late fall collecting trip to Western Myanmar, three specimens of a strange looking noctuid species externally somewhat similar to the Western Himalayan Mniotype leucocyma (Hampson, 1907) were collected. After examination of its male and female genitalia, this species was proven to be new to science. Moreover, the male genitalia of the new species show a surprisingly unusual complex of features, some of which, together with the female genitalia, are characteristic and decisively significant to the subtribe Xylenina. The male and female genitalia of this species are most similar to those of the genera Eupsilia Hübner and Owadaglaea Hacker & Ronkay, however, these genitalia have certain autapomorphic characters which clearly justify separation on generic level. The description of the new genus and species is given below with a comparison to the related Eupsilia and Owadaglaea, several other related genera (Lithophane Hübner, Conistra Hübner and Xylena Ochsenheimer) and the externally similar M. leucocyma as well.

This work focuses on the environment protected, ecological procedure by the combination of ZnO nanoparticles utilizing the extraction of Ocimum sanctum. The prepared nanoparticles are examined by different methods like Fourier-transform infrared spectroscopy (FTIR), X-ray Diffraction
(XRD), Field emission scanning electron microscopy (FE-SEM), Energy Dispersive X-ray Analysis (EDAX). A systematic study has been made on the result of ZnO nano-coating for the corrosion behavior of mild steel. The ZnO nanoparticles of average diameter in the range 18–22 nm were coated
on mild steel in nickel bath solution. The anticorrosion properties on the coated mild steel was carefully tested in 3.5% NaCl solution by performing potentio-dynamic polarization measurement and electrochemical impedance spectroscopy. Surface morphology of the coated mild steel immersed in
corrosive solution was judged by using SEM with EDAX. The ZnO nano coating has shown a perfect protection against corrosion and the shielding capability is in the range between 86–95%. The incorporation of ZnO nanoparticles has upgraded the process of mild steel in all corrosion media
are subjected to investigation.
Microstructural Changes with Annealing of a Nanostructured Al Alloy Severely Plastic Deformed by Four-Layer Stack Accumulative Roll-Bonding Process
Authors: Lee Seong-Hee
Published: January 2020

Microstructural changes with annealing of a nanostructured complex aluminum alloy fabricated by 3 cycles of four-layer stack ARB process using different Al alloys were investigated in detail. The four-layer stack ARB process using AA1050, AA5052 and AA6061 alloy sheets was performed
up to 3 cycles without a lubricant at room temperature. The sample fabricated by the ARB is a multi-layer aluminum alloy sheet in which the AA1050, AA5052 and AA6061 aluminum alloys are alternately stacked to each other. The layer thickness of each alloy became thinner and elongated to the
rolling direction with the number of ARB cycles. The grain size decreased with increasing of the number of ARB cycles, and became about 160 nm in thickness after 3 cycles. The complex Al alloy still showed ultrafine grained microstructure to annealing temperature of 300 °C, but it had
a heterogeneous structure containing both the ultrafine grains and the coarse grains due to an occurrence of discontinuous recrystallization after 350 °C.
Nucleation of W-Rich Laves Phase Nanoparticles in Tempered Martensite Ferritic Steel During Long-Term Aging at Elevated Temperature
Authors: Kim Chungseok
Published: January 2020

The nucleation of W-rich Laves phase nanoparticles was studied during long-term aging at elevated temperature in tempered martensite ferritic steels (TMFS). The TMFS was fabricated by vacuum induction melting (VIM) process. The long-term aging tests are interrupted at various stages
to simulate the different level of nucleation of intermetallic phases. In the present work, we employ scanning electron microscopy (SEM), Auger electron microscopy (AES), and transmission electron microscopy (TEM) to study the formation nucleation of Laves phase particles. We investigated
the preference of Laves phase particles to nucleate next to M23C6 micrograin boundary carbides due to the segregation of W from the matrix to the micrograin boundaries.

Recently oxide-based thin-film transistors (TFTs) are investigated for emerging applications of the next generation display devices and other electronic circuits (Fortunato, E., et al., 2012. Oxide semiconductor thin-film transistors: A review of recent advances. Advanced Materials,
24, pp.2945–2986). Despite of the great success in n-type oxide semiconductors with high transparency and high field-effect mobility, high performance P-type oxide TFTs are so highly desired that complementary circuits can be realized with low power and high performance
(Ou, W.C., et al., 2008. Anomalous P-channel amorphous oxide transistors based on tin oxide and their complementary circuits. Applied Physics Letters, 92, p.122113). There are some oxides such as SnO, CuO, Cu2O and NiO are regarded as promising P-type semiconductor
materials. In this investigation, tin oxide SnOx is fabricated to be active layer for TFTs device, and furnace annealing with several combinations of nitrogen and oxygen ambient is compared to enhance the electrical characteristics of P-type SnOx TFTs (Park, K.S.,
et al., 2009. High performance solution-processed and lithographically patterned zinc-tin oxide thin-film transistors with good operational stability. Electrochemical and Solid-State Lett., 12, pp.H256–H258). The results show that with N2+O2 ambient, 30 minutes
furnace annealing, the P-type SnOx TFTs device shows better performance with mobility (μFE) 0.883 cm2/V · S, threshold voltage (VT) −4.63 V, subthreshold swing (SS) 1.15 V/decade, and Ion/Ioff
ratio 1.01×103.

Amorphous InGaZnO (a-IGZO) Thin Film Transistors (TFTs) has been studied extensively for their perspective applications in next generation active-matrix displays such as liquid crystal displays and flat-panel displays, due to its better field-effect mobility (>10 cm2/V
· S), larger Ion/Ioff ratio (>106), and better stability electrical. Hydrogen is known as shallow donors for n-type (channel) oxide semiconductors (Dong, J.J., et al. 2010. Effects of hydrogen plasma treatment on the electrical
and optical properties of Zno films: Identification of hydrogen donors in ZnO. ACS Appl. Mater. Interfaces, 2, pp.1780–1784), and it is also effective passivator for traps (Tsao, S.W., et al., 2010. Hydrogen-induced improvements in electrical characteristics of a-IGZO thin-film
transistors. Solid-State Electron, 54, pp.1497–1499). In this study, In-Situ hydrogen plasma is applied to deposit IGZO channel. With atmospheric-pressure PECVD (AP-PECVD), IGZO thin film can be deposited without vacuum system, large area manufacturing, and cost reducing
(Chang, K.M., et al., 2011. Transparent conductive indium-doped zinc oxide films prepared by atmospheric pressure plasma jet. Thin Solid Films, 519, pp.5114–5117). The results show that with appropriate flow ratio of Ar/H2 plasma treatment, the a-IGZO TFT device exhibits
better performance with mobility (μFE) 19.7 cm2/V · S, threshold voltage (VT) 1.18 V, subthreshold swing (SS) 81 mV/decade, and Ion/Ioff ratio 5.35×107.

In this study, walnut-shaped V2O3 particles with high photocatalytic activity in the visible light were synthesized by hydrothermal process. The V2O3 samples synthesized with the various temperature conditions of the hydrothermal process were
characterized using XRD, SEM, TEM, UV-Visible spectrometer and N2gas adsorption/desorption analysis. For investigating the photocatalytic performance of synthesized V2O3 particles in the visible light condition, photodegradation experiments of methylene blue
(MB) solution under artificial sunlight irradiation was conducted. As a result, the V2O3 hydrothermal-synthesized at 280 °C was composed of pure V2O3 crystal structure and showed high photocatalytic activity for the degradation of MB dye in visible
light.

Authors: Kim Yong-Ho , Yoo Hyo-Sang , Son Hyeon-Taek
Published: January 2020

In this research, effects of Zn and Cu content on microstructure, mechanical properties, electric and thermal conductivity of the as-extruded Al-x(Zn+0.5Cu) alloys were investigated. As the content of Zn and Cu increased, the area ratio of Al2Cu intermetallic compounds
increased. After homogenization treatment and extrusion process, most of Al2Cu intermetallic compounds was disappeared due to solution in Al matrix of Cu atoms. As the (Zn+0.5Cu) content increased from 1 to 2 wt.%, the average grain size decreased remarkably from 645 to 227 μm
due to the dynamic recrystallization caused by the solute Zn and Cu atoms during the extrusion. With increasing Zn and Cu additions, the thermal conductivity was decreased from 225 (x = 1) to 208 (x = 2) and 183 W/mK (x = 4) due to electric scattering by solute Zn and
Cu atoms. The ultimate tensile strength (UTS) of the as-extruded Al-x(1Zn+0.5Cu) alloys improved remarkably from 77 (x = 1) to 142 MPa (x = 4) as Zn and Cu content increased, and the elongation increased from 30 to 33%. This improvement in the strength resulted from the
grain refinement and solid solution strengthening due to the solute Zn and Cu atoms. The Zn and Cu addition in Al alloy played an important role in thermal conductivity and mechanical properties.
Effects of Density and Diameter on Surface Optical Phonon Modes in GaAs Nanowire Bundles

Published: January 2020

We report the systematic investigation of the surface optical phonon modes in Au-catalyzed GaAs nanowires grown on an Au pre-patterned GaAs(111)B substrate using μ-Raman spectroscopy. We employed electron-beam dose rate as a control parameter during the substrate patterning
step for adjusting the nanowire base diameter and coverage, which are independent from the nanowire growth conditions. We have experimentally studied the effect of the fill factor and average diameter on the surface optical phonon modes and explained the red-shift and broadening of the surface
optical phonon frequencies by employing the dielectric continuum model. The surface optical phonon mode shift is exhibited to be sensitive to fill factor, rather than base diameter. The decrease in the average diameter from 280 nm to 180 nm results in the asymmetric broadening and red-shift
of the surface optical phonon frequency (~1.83 cm−1) but the theoretical calculation from the isolated single nanowire-based dielectric continuum model cannot solely explain the behaviors of the surface optical phonon mode. In contrast, the change in the fill factor from 0.01
to 0.83 results in a shift of the surface optical phonon frequency (~6.5 cm−1) from the GaAs bulk value. The red-shift and asymmetric broadening of the surface optical phonons, in an agreement with the Maxwell-Garnett approximation, are consequences of dipolar interaction
of randomly aligned neighboring nanowires and the polar nature of GaAs nanowire bundles. This work suggests the pre-patterning parameter dependent surface optical phonon characteristics of GaAs nanowire bundles which are of great importance in the nondestructive characterization of low-dimensional
opto-electronic materials and devices.
