Hybrid Hydrogen Peroxide for Viral Disinfection
Authors: Hislop Meaghan , Grinstead Frances , R. Henneman John
Published: November 2021

Decontamination is often necessary in facilities with sensitive spaces where pathogen elimination is critical. Historically, high concentration vaporized hydrogen peroxide technologies have been applied in these areas for pathogen disinfection. While effective, these high concentration solutions come with inherent risks to human health and safety. Alternatively, one recent innovation is a hybrid hydrogen peroxide system which combines a 7% hydrogen peroxide solution with a calibrated fogging device that delivers a mixture of vaporous and micro aerosolized particles, significantly lowering the risk of exposure to high-concentration hazardous chemicals. Studies performed with this technology demonstrate high level pathogen decontamination across a variety of tested pathogens and substrates. This chapter will cover a brief history of hydrogen peroxide technologies and their application processes; examine the correlations between viral inactivation, viral disinfection, and biological indicators for validation; demonstrate the necessity of dwell time for optimal efficacy; discuss the effects of viral disinfectant use on laboratory surfaces; and examine various studies, including virologic work performed in Biosafety Level 3 facilities and good laboratory practice (GLP) data performed by EPA-approved laboratories. This chapter will provide readers a deeper understanding of essential components and considerations when implementing hydrogen peroxide systems for viral decontamination.
Diagnosis of Pulmonary Embolism
Authors: M. Patil Sachin
Published: November 2021

Pulmonary embolism is an acute emergency due to the occlusion of the pulmonary arteries by a venous blood clot. The pathophysiology of pulmonary embolism follows Virchow\'s triad, which encompasses stasis in veins, increased coagulation, and vessel wall trauma. Pregnancy, major trauma or surgery, prolonged immobilization, obesity, medication, and inherited risks are important risks. It is an essential rule-out diagnosis in chest pain and dyspnea patients in the emergency room. It is also responsible for significant mortality if not diagnosed and treated promptly. Physicians utilize multiple algorithmic scores and calculators to supplement diagnosis along with a high degree of clinical suspicion at initial presentation. Clinical diagnosis involves utilizing multiple modalities, including D-dimer, troponin, arterial blood gas analysis, electrocardiogram, bedside echocardiogram, and imaging modalities such as venous duplex, chest computed tomography, ventilation-perfusion scans, and pulmonary angiogram. Some imaging modalities carry the risk of radiation and being invasive. The treatment can itself be short-term or lifelong based on the causative factor. Anticoagulants used in the therapy can itself cause devastating complications if not monitored appropriately. Despite adequate treatment, some of these patients progress to chronic disease resulting in secondary pulmonary hypertension.
Lymphoma and the Microenvironmental Cross-Talk between Sex Hormone Receptors and Epstein-Barr Virus in Predicting Lymphoma Clinical Status
Authors: J. Alkhatib Ahed
Published: November 2021

Lymphoma is a significant clinical entity because of its high incidence and complicated etiology and pathology. In this chapter, we discussed lymphoma in general and made focus in our previous studies in which we found unique features linking the interaction of EBV with sex steroid hormones in lymphoma cells. Sex steroid hormones included estrogen receptor and progesterone receptors that were investigated for their expression in malignant lymphoid cells. The localization of EBV in malignant lymphoid cells was also investigated. The two main types of lymphoma, Hodgkin Lymphoma, and non-Hodgkin lymphoma, were investigated for the interaction of EBV with sex steroid hormones. Unique features were obtained in terms of a bridge-linking estrogen receptor with EBV in Hodgkin lymphoma and progesterone receptor with EBV in non-Hodgkin lymphoma. The interactions between EBV and lymphoma are classic, but the reasons beyond this are not well established. The results of our studies highlighted new features by the existence of expressed sex steroid receptors. We think that the dissociation of combination between sex steroid hormones and EBV bears the link to design new therapeutic strategies for lymphoma.
Derotational Osteotomies for The Late Treatment of Brachial Plexus Injury
Authors: Emrah Açan Ahmet , Şahin Ertuğrul
Published: November 2021

Obstetric brachial plexus palsy [OBBP] can affect the function of the upper extremity. Most of the injuries are limited to the upper spinal nerves and heals spontaneously. However, some of them will have incomplete recovery after OBBP often results in weakness of the external rotators [teres minor and infraspinatus] muscles compared to the internal rotators [teres major, pectoralis major, latissimus dorsi] muscles. The predominance of the internal rotators and adductor muscles over external rotators leads to an internal rotation contracture. The development of internal rotational deformity may progress to increased glenoid retroversion and posterior humeral head subluxation. If the surgeon does not repair internal rotation deformity, the humeral head is forced into a posterior position causing a complete posterior dislocation. Many procedures are performed to treat these deformities: In the young child, improving the remodeling of the glenohumeral joint, capsulectomy, and subscapular release are introduced. Tendon transfers of the shoulder have good results for motion but fail to restore the glenohumeral joint. The failure of improving joint alignment may represent the loss in clinical improvement over time. In older children, a humeral osteotomy can be an alternative to realign the limb into external rotation, improve appearance, and enhance eating, washing hair, and scratching the back of the neck. We will discuss all the techniques along with their advantages and disadvantages.
Juvenile Idiopathic Arthritis
Authors: Javadi Parvaneh Vadood , Rahmani Khosro
Published: November 2021

Juvenile idiopathic arthritis (JIA) is the most common form of chronic synovial joint inflammation in children. It potentially leads to disability and psychosocial outcomes for children and their families. In the absence of appropriate treatment, this can lead to joint destruction and disability. Thus, early diagnosis and aggressive treatment are essential. With the presentation of new biologic DMARDs, based on understanding the disease pathophysiology and molecular pathogenesis, the course of the disease and its outcome have been changed profoundly. In this chapter, the early diagnosis, appropriate treatment, and outcomes approaches are described. These include the latest diagnosis and management options.
Crossroads of Higher Education in Troubled Times Facing the Future of Work and the Subjective Well-Being of Professionals in Latin America
Authors: Iturrieta Olivares Sandra
Published: November 2021

The effects of massification, fragmentation and segmentation in higher education have been exacerbated by the state of current affairs. Latin America has been especially shaken, due to e.g., political changes resulting from massive expressions of social discontent following 2019; or the arrival of COVID-19, its interruption of the quotidian, and its impetus for technology to burst into professional work. In this context, three major crossroads for higher education – resulting from bibliographical and document analysis and integration – are presented in the paper, “Rethinking undergraduate training in social sciences from the imaginaries of the future about professional work”. The paper discusses development in the current context, the future of professional work, and subjective well-being in professionals. To face these challenges, the conclusions propose the exercise of prognostic intelligence as an alternative. Prognostic intelligence is a professional skill that can be developed during higher education. Its practice would eschew the presentism characteristic of our turbulent times in favor of expanding the possibilities of outlining the future of higher education on the basis of relevance, quality, and stability.
Immunotherapy and Systemic Treatment of Cutaneous Squamous Cell Carcinoma
Authors: Aboul-Fettouh Nader , Morse Daniel , Patel Jigar , Migden Michael R.
Published: November 2021

Cutaneous squamous cell carcinomas (cSCC) represent one of the most diagnosed non-melanoma skin cancers and its incidence is increasing globally. Whereas early stage and low risk cSCC is typically treated with surgery, and in some cases other localized therapeutic modalities, locally advanced or metastatic cSCC is a cause of significant morbidity and mortality that requires a different approach to therapy. Therapeutic attempts at treating advanced cSCC include a multi-disciplinary approach with considerations for surgery, radiation, and systemic therapies. In this review, we will discuss the various systemic therapies that have been trialed for advanced cSCC, beginning with the early cytotoxic and platinum-based agents as well as their corresponding limitations. We will then review the targeted approaches using EGFR inhibitors prior to discussing the more recent immunotherapeutics that have shown good tumor responses in this often-lethal disease.

Compreender as variações espaciais de variáveis dendrométricas em inventário florestal contínuo é imprescindível para subsidiar ações de manejo, além de permitir intensidades amostrais que reflitam em acurácia com menor custo do inventário. Nesse contexto, o objetivo deste trabalho foi avaliar a estrutura de dependência espacial de variáveis dendrométricas ao longo do tempo e em diferentes intensidades amostrais em povoamento de eucalipto. As hipóteses testadas foram que a estrutura de dependência espacial de variáveis dendrométricas se altera com o crescimento em povoamentos de eucalipto e que a intensidade amostral influencia nesta estrutura. As variáveis diâmetro a 1,30 m do solo, área basal, altura total, altura média das árvores dominantes e volume de madeira foram obtidas em inventário florestal contínuo, aos 3,5, 4,5 e 5,5 anos, em 80 unidades amostrais permanentes (400 m²), distribuídas aleatoriamente em um povoamento de eucalipto (394 ha), localizado em Abaeté, Minas Gerais. Foram avaliadas as intensidades de uma unidade amostral a cada 4,9 (n = 80), 7,3 (n = 54) e 16,4 (n = 24) hectares. Considerou-se a maior intensidade amostral como referência para as demais. Os modelos de semivariância esférico, exponencial e gaussiano foram ajustados ao semivariograma experimental, em que o modelo de melhor ajuste foi utilizado pela krigagem ordinária na espacialização das variáveis analisadas. Os resultados demonstraram predominância de forte dependência espacial das variáveis dendrométricas, independentemente da idade e intensidade amostral, sobretudo para altura média das árvores dominantes e volume de madeira. A menor intensidade amostral influenciou negativamente na dependência espacial da área basal, em todas as idades. A estrutura de dependência espacial não é influenciada pelo aumento da idade do povoamento, sendo recomendada a análise geoestatística destas variáveis em inventário florestal contínuo, considerando a intensidade amostral de uma unidade amostral a cada 16,4 hectares.

Considerando que a formulação de índices de perigo de incêndios auxilia no planejamento das atividades de prevenção e combate, refletindo de forma antecipada a probabilidade de ocorrência e de propagação dos incêndios florestais, o presente trabalho teve por objetivo realizar o ajuste e validação da Fórmula de Monte Alegre para áreas de cultivo de eucalipto no Estado de São Paulo. Foram utilizados dados de umidade relativa do ar, precipitação pluviométrica e registros de ocorrência de incêndios florestais no período de 11/10/2003 a 29/04/2016. Para a análise, o conjunto de dados foi dividido em duas partes, sendo que as observações entre os anos de 2003 e 2013 (75%) foram utilizadas para o ajuste da FMA, enquanto os dados referentes aos anos de 2014 a 2016 (25%) foram utilizados para validar a nova classificação gerada conforme o estabelecimento dos novos valores limiares de distinção entre a classes de perigo de incêndios. Os resultados demonstraram que o estabelecimento de novos limiares para as definições das classes de perigo proporcionou melhorias na eficiência da Fórmula de Monte Alegre em prever a ocorrência de incêndios na região de estudo.

Published: November 2021

A biodiversidade da Mata Atlântica é considerada de extrema importância biológica, mas essa riqueza de fauna e flora está ameaçada pelo desmatamento. O objetivo deste estudo consiste em apresentar um modelo de avaliação da perda da biodiversidade, adotando como cenário o município de Viçosa do Ceará, situado no Nordeste brasileiro. O método adotado baseia-se na proposição de um indicador em que se busca calcular a estimativa da perda da biodiversidade a partir do decréscimo da riqueza de aves, mamíferos e répteis escamados que fazem parte desse habitat, tendo como referência o modelo da relação espécie-área. Como resultados tem-se: (1) a perda da biodiversidade na área de estudo está em nível “extremo”; (2) as taxas de variação média e de velocidade têm movimento acelerado, logo, quanto maior for o aumento da área desmatada, mais rápida se torna a velocidade e aceleração da perda da biodiversidade; (3) a curvatura da função indicou que o ponto crítico da perda da biodiversidade acontece quando o desmatamento atinge 93% da área do ecossistema. Conclui-se que o modelo de estimativa da perda de aves, mamíferos e répteis escamados apresentou-se de forma eficiente para a avaliação da perda da biodiversidade no ecossistema de Mata Atlântica.

O uso de genótipos resistentes é um dos principais métodos de controle de doenças no Brasil, sendo fundamental o melhoramento genético visando a obter novos genótipos resistentes, para suprir essa demanda. Assim, o objetivo deste trabalho foi estimar os parâmetros genéticos das variáveis resistência ao cancro, causado por Chrysoporthe cubensis e resistência à mancha foliar, causada por Cylindrocladium spp. e Kirramyces epicoccoides, bem como avaliar suas implicações na estratégia de melhoramento genético de Eucalyptus grandis. Foi instalado um teste de progênies de polinização aberta, em dois locais no Estado de São Paulo, nas regiões de Anhembi e Itatinga. O teste foi realizado em blocos casualizados, com 176 progênies e três testemunhas, uma por parcela, com 30 repetições em Itatinga e 28 repetições na região de Anhembi. A resistência ao cancro foi avaliada aos 12, 24 e 29 meses de idade na região de Anhembi e aos 15, 27 e 32 meses de idade, na região de Itatinga. A resistência à mancha foliar foi avaliada aos 12 e 24 meses de idade na região de Anhembi e aos 15 e 27 meses de idade, na região de Itatinga. Os parâmetros genéticos foram estimados, utilizando o software SELEGEN REML/BLUP®. Com a mesma população de seleção, verificou-se que, para a região de Itatinga, as estimativas de parâmetros genéticos indicam maior potencial para a seleção de genótipos resistentes ao cancro e à mancha foliar. Porém, para as condições edafoclimáticas da região de Anhembi, essa população apresenta potencial de seleção inferior, o que fica evidenciado pelos baixos valores de herdabilidade média individual de progênies estimados. Na região de Itatinga, foram obtidos valores de herdabilidade média individual de progênies para a resistência ao cancro e à mancha foliar, que variaram de moderado a alto, indicando que pode haver bons ganhos com a seleção neste local.

Published: November 2021

Introduction : Depuis mars 2020, le Québec (Canada), comme le reste du monde, vit une crise sanitaire majeure résultant de la pandémie de COVID-19. En plus des nombreux décès occasionnés par le virus, des personnes vivront leur fin de vie dans ces temps mouvementés où les mesures d’urgence sanitaire forcent leur isolement et modifient en profondeur l’organisation et la pratique des soins de fin de vie. Au Québec, 64 % des personnes qui sont décédées étaient des résidents de Centre d’hébergement et de soins de longue durée (CHSLD), une population considérée hautement vulnérable. Cependant, le risque de mourir de la COVID-19 est inégal entre les régions sociosanitaires du Québec, suggérant, par le fait même, la possibilité que des mesures organisationnelles et cliniques différentes aient été mises en place dans divers milieux.Objectif : L’article présente le protocole d’une étude visant à mieux comprendre les effets de la COVID-19 sur les soins de fin de vie en CHSLD par l’identification de transformations organisationnelles et cliniques ainsi que le contraste de deux régions différemment affectées, soit Montréal et l’Estrie.Méthodes : Un devis descriptif-explicatif est utilisé. Des entrevues sont réalisées avec les coordonnateurs de site et les soignants ayant travaillé en CHSLD durant la première vague de COVID-19 afin d’identifier les transformations vécues et leurs effets sur les soins offerts aux résidents en fin de vie, ainsi que sur le personnel soignant.Discussion et conclusion : Les conclusions de ce projet mèneront à des recommandations sur le plan organisationnel, clinique, politique et scientifique.

Introduction : Les infirmières sont exposées régulièrement à des événements difficiles dans leur travail. Dès le début de l’année 2020, cette exposition, augmentée dans le contexte de la pandémie de COVID-19, fragiliserait leur santé psychologique. À ce jour, le portrait de la santé psychologique de ces professionnelles de la santé et ses déterminants dans le contexte québécois demeurent méconnus, mais nous pouvons anticiper que la pandémie affecte négativement la santé psychologique des infirmières.Objectifs : Cet article décrit le protocole de recherche d’une étude observationnelle transversale chez les infirmières du Québec. Cette étude vise à produire des données probantes sur la santé psychologique de ces infirmières pendant la pandémie.Méthodes : Ce protocole est publié rétrospectivement à la collecte de données qui a été réalisée entre juillet et septembre 2020. Un total de 15 000 infirmières du Québec sélectionnées à l’aide d’un échantillonnage aléatoire simple ont été invitées à répondre à un sondage en ligne. Des statistiques descriptives et des analyses de régressions multivariables seront utilisées pour décrire les participantes et leur santé psychologique et ses déterminants.Discussion et conclusion : Les résultats anticipés de cette étude seront comparés à la littérature sur le sujet. En effet, d’autres auteurs ont mesuré la santé psychologique dans différents contextes (épidémie, pandémie, pays, population). Ces résultats serviront de base pour développer et déployer une intervention à l’échelle provinciale afin d’améliorer la santé psychologique de cette population de travailleurs.
Una lengua meta y dos realidades distintas: la traducción de la literatura infantil y juvenil francesa al euskera
Authors: Zubillaga Gomez Naroa
Published: November 2021

El objetivo de este artículo es realizar un estudio descriptivo del sistema compuesto por las traducciones al euskera de las obras francesas de literatura infantil y juvenil. Para ello, y tras consultar diferentes bases de datos, se ha completado un catálogo que ha dado como resultado 754 entradas de LIJ francesa traducida al euskera. Más de la mitad de las entradas se refieren a obras destinadas a los más pequeños (0-9 años) y el género del cómic también está muy representado, pues supone el 18% de todo el catálogo. Además, llama la atención la cantidad de autores que se han traducido, aunque no son muchos los autores que se escogen más de una vez. En cuanto a los traductores, cabe destacar la función de las agencias de traducción, quienes aparecen en los créditos como los responsables de haber realizado la labor de traducir los libros destinados a los más pequeños. Sin embargo, el dato más interesante es el relativo al lugar de publicación, ya que, aunque la lengua origen sea el francés, tan solo el 9,5% de las entradas del catálogo fueron publicadas en el País Vasco francés. Esto se debe, sobre todo, a la situación de no-oficialidad que vive la lengua vasca en el estado francés, y hace que surjan dos sistemas diferentes a un lado y al otro de la frontera, a pesar de que las lenguas origen (francés) y meta (euskera) sean las mismas.
Currículos Outros, Sujeitos Outros: novas paisagens no território curricular a partir de uma narrativa-experiência docente
Authors: Araujo de Oliveira Danilo , Ferrari Anderson
Published: November 2021

Nosso foco de problematização se inscreve nas relações entre currículo e subjetividades, tomando como provocação a narrativa-experiência de uma professora universitária no encontro com o imprevisível da sala de aula. Perseguindo esse foco de problematizar as relações entre o currículo e as subjetividades, organizamos o texto em três partes: a expectativa, o encontro e a mudança. Todas essas partes dizem e dão forma à narrativa-experiência da professora junto às alunas e aos alunos e seus questionamentos em torno do currículo e de si mesma como resultado desse currículo, mas, sobretudo, nos conduzem para as potencialidades da sala de aula na construção de outros currículos e outros sujeitos. As perspectivas teórico-metodológicas que orientam nossas análises são a pós-critica de currículo e a inspiração dos estudos de Michel Foucault. A narrativa-experiência aqui acionada por nós para pensar o território curricular mostra que, entre os seus ordenamentos, o currículo demanda um tipo específico de professora e professor, aquela e aquele que busca se munir de ferramentas e garantir a realização de um plano e conduzir sua conduta de certo modo, mas, no encontro com o imprevisível do currículo, essa posição de sujeito professora esvanece. Nossa defesa é de que, na sala de aula, emergem possibilidades de constituição de novas paisagens no território curricular que, como efeito, permitem a constituição de currículos outros e sujeitos outros.
Cognição como atividade humana criadora em vivências de estudantes de pedagogia
Authors: Cardoso Gomes Maria de Fátima , Ferraz Almeida Neves Vanessa , Prazeres Silva Luciana
Published: November 2021

Neste artigo discutimos diferentes trajetórias escolares por meio de Estudos de Casos de três estudantes de uma turma de Psicologia da Educação, do Curso de Pedagogia da Universidade Federal de Minas Gerais e seus familiares. As estudantes e seus familiares relataram vivências (perejivânia) tensas e dolorosas nessas trajetórias. Tais vivências nos impulsionaram a perguntar: Como pensar a cognição como uma atividade humana criadora? Como relacionar a cognição com as práticas sociais em que ela é gestada? No contexto das salas de aulas daquela universidade, os letramentos acadêmicos foram ressaltados nos discursos das estudantes e pudemos conhecer a força do afeto constituindo e sendo constituído pela cognição social situada, pela força das culturas e das linguagens em uso. Argumentamos que esses conceitos estão intimamente relacionados nas vivências relatadas, em alguns momentos um ou outro se torna mais saliente, porém estão sempre em diálogo, constituindo as pessoas. O diálogo entre teoria e empiria levou-nos à compreensão da indissociabilidade entre afeto, cognição, culturas e linguagens e, consequentemente, à proposição de uma síntese: a unidade de análise [afeto/cognição social situada/culturas/linguagens em uso] — ACCL — com base na Psicologia Histórico-cultural, que defende a unidade afeto/cognição, e na Etnografia em Educação, que argumenta que culturas e linguagens em uso são inseparáveis. A unidade ACCL permitiu-nos olhar para as pessoas, humanizando suas trajetórias escolares, bem como possibilitou-nos não as estigmatizar ou rotulá-las como deficientes.

Este artigo tem como objeto de estudo o processo de formação continuada para professores técnicos em um Centro de Educação Profissional do Semiárido, no Território de Identidade do Sisal, na Bahia, focalizado a partir de atitude orientada ao consenso, pelo viés de uma racionalidade comunicativa. Esse processo formativo é discutido com interfaces de saberes e práticas pedagógicas buscando contribuir para o desenvolvimento da profissionalidade docente do professor técnico, por meio da reflexão de concepções e de práticas pedagógicas. Assim, este artigo busca compreender como a formação continuada favorece o sobrepujamento do agir estratégico docente para um agir comunicativo na prática de ensino a fim de refletir sobre sua profissionalidade docente. A metodologia está embasada nos conceitos da pesquisa colaborativa, desenvolvida a partir de sessões reflexivas e de entrevistas semiestruturadas com professores técnicos sobre seu fazer docente e sua profissionalidade. Como resultado, para que esses técnicos tenham mais identificação com a docência, aponta-se a importância de processos formativos no espaço escolar, que surjam das próprias realidades educativas locais, de forma dialógica e engajada e contribuam para a ressignificação do trabalho do professor, no sentido de possibilitar

Published: November 2021

A preocupação em relação à adoção de novas posturas no serviço público pautadas pelo comportamento focado na sustentabilidade do Planeta, bem como na adoção de processos mais racionais no serviço público, lança o seguinte problema: a adoção de critérios sustentáveis tem sido uma realidade na administração pública? Sendo assim, decidiu-se realizar essa pesquisa a partir de referencial teórico e do acesso aos dados secundários disponibilizados no sistema de licitação da Universidade e no comprasnet; com o objetivo de analisar a aplicação de licitações sustentáveis em instituições de ensino superior públicas. O método utilizado foi o dedutivo partindo da análise dos processos administrativos e do comportamento dos servidores públicos e revisão bibliográfica. Verificou-se um subaproveitamento dessa figura legal que aponta para a necessidade urgente de uma mudança de postura na administração pública federal, através de um planejamento baseado numa reestruturação de prioridades em termos de compras públicas.

Authors:   Universidad de Murcia (España), Rojo López Ana , Cifuentes Férez Paula ,   Universidad de Murcia (España), Ramos Caro Marina ,   Universidad de Murcia (España)
Published: November 2021

The present study researches the correlation between translators’ creative personality and their behaviour by using a combination of psychological, key-logging and screen-recording methods as well as the evaluation of participants’ translation output. Participants were asked to translate a literary text without knowing that it posed the additional challenge of transferring manner of motion verbs into Spanish. The experiment correlated the participants’ scores on a validated creativity test (i.e., CREA, Corbalán Berná et al., 2003) with their scores on process indicators of fluency as one of the key dimensions of creativity as well as product indicators of flexibility, novelty, and accuracy. To this purpose, the logging tool Inputlog was used to measure dwell ratio, total translation time, time interval between ST processing and TT production and time devoted to revision. The screen recording software CamStudio was also used to analyse participants’ creativity in searching and retrieving information. Although few significant statistical results were found, our study suggests that creative translators’ potential can be traced both in their translation product and process.

Efficiency of Polymer Light‐Emitting Diodes: A Perspective
Authors: Van der Zee Bas , Li Yungui , Wetzelaer Gert‐Jan A. H. , Blom Paul W. M.
Published: November 2021

The various contributions to the external quantum efficiency (EQE) of polymer light‐emitting diodes (PLEDs) are discussed. The EQE of an organic light‐emitting diode is governed by a number of parameters, such as the electrical efficiency, the photoluminescence quantum yield (PLQY), the optical outcoupling efficiency and the spin statistics for singlet exciton generation. In the last decade, the electrical efficiency has been determined from a numerical PLED device model. More recently, an optical model to simulate the fraction of photons outcoupled to air for PLEDs with a broad recombination zone has been developed. Together with the directly measured PLQY, the EQE of a PLED can then be estimated. However, it has been observed that the measured EQEs of fluorescent PLEDs, including the model system super‐yellow poly(p‐phenylene vinylene) (SY‐PPV) often exceed the expected values. To solve this discrepancy, it is demonstrate that the electrical PLED model has to be expanded by the inclusion of triplet–triplet annihilation (TTA), which is shown to be responsible for a substantial EQE enhancement. Experimentally, it is obtained that TTA contributes to a singlet‐exciton generation efficiency of ≈40% in SY‐PPV PLEDs, giving rise to an EQE of ≈4% instead of the expected value of 2.5%.

Published: November 2021

Methylammonium lead iodide perovskite (MAPbI3) is today considered the most promising component for highly efficient third generation solar cells. However, the lifetime of the solar devices is strongly affected by the stability of the MAPbI3 films toward humidity, UV irradiation, and temperature. The search for efficient protective additives to be used for building up composite perovskite films with enhanced stability is a topic of great interest in the scientific community. In the present paper, a layered zirconium phosphate‐phosphonate based on N,N‐phosphonomethylglycine, exfoliated in thin nanosheets (NS), as additive for the stabilization of MAPbI3 crystalline films toward humidity, UV‐irradiation, and temperature changes is applied. Notably, the additive is extremely efficient in preventing degradation of the perovskite film, preserving the optical and structural properties, and avoiding the phase transitions normally observed due to temperature increase.

Published: November 2021

Invisible photonic patterns based on responsive photonic crystals show great potential in structural‐color encryption. However, single inherent information (structural color) encryption/decryption means and the incomplete invisibility in normal conditions greatly limit further development in high‐precision encryption. Here, a novel invisible photonic pattern encrypted/decrypted by dual optical information (structural color and brightness) is reported. It is prepared by engineering an extremely large wettability difference into the patterned and unpatterned regions of a vapor‐responsive inverse opal film. The same optical properties and the distinct wettability difference between the two regions not only ensure that the pattern encrypted by structural color and brightness in the normal state can be entirely hidden under the microscope, but also ensure that it can be decoded by large color contrast (Δλ = 26–32 nm) and brightness contrast (ΔB = 48–57.6) under flowing water vapor state. The unique invisible photonic pattern, reported for the first time, can inject new life into structural color‐based encryption.

The second near‐infrared (NIR‐II) window is highly effective in fluorescent bioimaging to obtain a deep view of living systems. Among numerous NIR‐II fluorescent agents, organic fluorophores have been considered as ideal candidates in this field. Thus, modulation strategies should be considered to improve the performance and functionality of such agents. This review provides an overview of the development and construction of organic NIR‐II fluorophores. More importantly, the modulation strategies focused on improving the performance and functionality of organic NIR‐II fluorophores are summarized and discussed in detail. Furthermore, the conclusion and future directions of the modulation strategy are presented as well.

Two novel homomultinuclear complexes [Co6(L)2(μ‐OAc)4]·2CHCl3·CH3COCH3 (1) and [Ni2(L)(H2O)2(Py)2]·2CHCl3 (2) with a newly designed rigid bis(salamo)‐type tetraoxime ligand (H4L) were synthesized and characterized by elemental analyses, Fourier transform infrared (FT‐IR) spectra, UV–Vis absorption spectra, and X‐ray single‐crystal diffractions. Complex 1 is a novel triple‐decker symmetrical six‐core cluster structure with twofold axis and inversion center. The Co(II) atoms were sandwiched between the bis(salamo)‐type ligands and possess two different geometries of distorted tetragonal pyramid and octahedron, respectively. Complex 2 possesses a dinuclear structure and the Ni(II) atoms are located in the N2O2 cavities of the ligand, and axial coordination atoms come from the coordinated water and pyridine molecules. Both Ni(II) atoms adopt distorted octahedral geometries. The interactions were quantitatively determined by Hirshfeld surfaces analyses of complexes 1 and 2. The coordination ratios were determined by studying the fluorescence properties of complexes 1 and 2. The results of fluorescence titration experiment show that the metals to ligand binding ratios are 6:2 and 2:1 for complexes 1 and 2, respectively.

The morphology and elemental compositions at the surface of poly(styrene sulfonic acid) (PSSA) grafted poly(ethylene‐co‐tetrafluoroethylene) polymer electrolyte membranes (ETFE‐PEMs) in a grafting degree (GD) range of 0%–127% are investigated by using FE‐SEM and XPS analyses. The concentrations of elemental components at the surface are not a linear function of GDs, resulting from different grafting speeds at the surface and bulk. In addition, low accumulation of PSSA grafts on the surface of ETFE‐PEMs in the low GDs of 0%–19%, as well as their homogeneous distribution through the membranes at least at a GD of 19% are observed. At higher GDs of 19%–127%, the PSSA accumulation on the surface is relatively limited, indicating the presence of more PSSA grafts inside the bulk than on the surface. The surface signatures of ETFE‐PEMs over the entire GD range can be determined based on the grafting process. These interesting observations suggest the significant advantages of interfacial properties of ETFE‐PEMs for fuel cell applications.

Poly(vinyl alcohol) (PVA)/chitosan (CS) blends represent one of the most studied bicomponent systems constituted between a natural biomacromolecule and an easily biodegradable synthetic polymer. Yet, in order to control and improve the physical, hydrolytic, and mechanical stability of these systems, by adding safe linkers to bind the free hydrophilic groups, there is much work to be done. In the present work, histamine (H) reinforced PVA/CS tri‐components blended films have been developed via casting from solution technique. Before casting, rheology measurements were conducted on the studied solutions, then, all the PVA/CS/H matrices were subjected to FTIR studies, scanning electron microscopy, contact angle, water absorption capacity, surface roughness measurements, antimicrobial, and in‐vitro biocompatibility studies. Results of the morphological studies showed that pores were uniformly dispersed on the matrix while the surface roughness increased in the films when a higher ratio of histamine was used. The studies revealed significant enhancement in the water absorption capacity of the histamine reinforced blends compared with the pristine PVA/CS film. Cellular behavior studies performed on epithelial (MCF line 7) cells revealed comparable proliferative and adhesion activity of tri‐component PVA/CS/H films compared to that of pristine PVA/CS films.
Spatio‐temporal feature fusion based correlative binary relevance for visual object detection
Authors: M Amaresh , S Chitrakala
Published: November 2021

Object detection in video is an emerging and challenging research topic in Computer Vision. Recently, deep learning based approaches achieves greater results in object detection. The major issues in detecting multiple objects from the videos are exploiting low‐level visual concepts and temporal information and also exploring the correlation between the objects in the videos. Therefore, to address the above mentioned issues, the spatio‐temporal feature fusion based correlative binary relevance (STFF‐CBR) classifier is proposed to generate a rich vector representation and exploit the label correlation for the object detection in videos. In this article, first, the spatio‐temporal feature fusion (STFF) is proposed to exploit the low‐level visual concepts and temporal information in the videos which significantly improves the object detection performance. Second, correlative binary relevance (CBR) classification approach is proposed to exploit the dependencies between the labels in the video using the nearest neighbor based label dependency graph (LDG). Additionally, feed forward neural network (FFNN) classifier is utilized to increase the classification accuracy of the CBR method. Experimental evaluation shows that the STFF‐CBR classifier model achieves better performance for object detection problem in video against the state‐of‐the‐art methods.

Child welfare practices in the last century have been linked to a high risk for child maltreatment and the subsequent development of mental ill‐health. However, not all affected individuals develop clinically relevant psychopathology, which can be considered as a form of resilience. Such resilience is insufficiently understood in survivors of an advanced age. Therefore, this exploratory study aimed to depict a resilience profile of Swiss older adult survivors of child welfare‐related maltreatment (n = 132; Mage = 71 years) and to contrast it with age‐matched controls (n = 125). Approximately 30% of survivors did not meet the diagnostic criteria for any of the assessed current or lifetime DSM‐5 disorders. These survivors were older, experienced less physical abuse, and had higher trait resilience, self‐esteem, income, and satisfaction with their socio‐economic status. They had lower levels of neuroticism and some empathy characteristics. Group differences in the resilience profiles suggest that resilience‐related aspects may vary as a function of past adversity.

Internet of underwater things (IoUT) has garnered significant attention for monitoring and exploration applications in underwater scenarios. The interconnected devices used in IoUT have power constraint as batteries are difficult to recharge or replace. Multihop cooperative communication can help reduce the power requirement of a single node by breaking the long distance links into two or more high quality segments. In this paper, we investigate the end‐to‐end average bit error rate (BER) of the multihop underwater relay network. The nodes are connected to each other using optical wireless communication link which provides high data rates with low latency. Closed form expressions for average BER are derived for two scenarios: (1) where every hop channel has the same statistical behavior and (2) each channel is characterized by different statistical behavior. Further, the impact of channel parameters on the system performance is analyzed and discussed.

Published: November 2021

Global level assumptions of numerical models have received relatively less attention, but have been indicated to be a major source of error in numerical modeling of Reinforced Concrete (RC) structures. In parallel, it has been stated that a statistical approach involving many virgin specimens and ground motions is necessary for model validation. Such an approach would require very small‐scale testing. Then, the reinforcement fabrication becomes a major issue. This paper proposes using additive manufacturing to fabricate the reinforcement cage. It presents the results from cyclic tests on 1:40 RC cantilever members. The cages were manufactured using an SLM 3D printer able to print rebars with submillimeter diameters. Different longitudinal and transverse reinforcement configurations were tested. A numerical model using existing Opensees elements was built and its parameters were calibrated against material level small‐scale tests. It captured the cyclic response of the RC members with a reasonable accuracy. The cyclic behavior of the RC members resembles the behavior of full‐scale RC members indicating that such small‐scale specimens can be used for the statistical validation of the global level assumptions of numerical models.
