    We assess the performance of generic text summarization algorithms applied to films and documentaries, using the well-known behavior of summarization of news articles as reference. We use three datasets: (i) news articles, (ii) film scripts and subtitles, and (iii) documentary subtitles. Standard ROUGE metrics are used for comparing generated summaries against news abstracts, plot summaries, and synopses. We show that the best performing algorithms are LSA, for news articles and documentaries, and LexRank and Support Sets, for films. Despite the different nature of films and documentaries, their relative behavior is in accordance with that obtained for news articles.Comment: 7 pages, 9 tables, 4 figures, submitted to Pattern Recognition Letters (Elsevier

    Model predictive control of an on-board fast battery charger for electric mobility applications

    Get PDF
    Under the necessities of reducing emissions and air pollution, and also for increasing fuel economy, automotive companies have been developing electric and plug-in hybrid electric vehicles. Since these vehicles are parked when the batteries are being charged, it is possible to use the traction power converter as on-board charger, also allowing to reduce weight, volume and costs of components in the vehicle. In this context, this paper presents a model predictive control algorithm for an on-board fast battery charging that uses the traction power converter of an electric vehicle. Simulation results and system implementation are depicted, and finally, are presented some experimental results obtained with the proposed control system.(undefined)info:eu-repo/semantics/publishedVersio

    O poder da vaidade e do autocuidado na qualidade de vida

    Get PDF
    Objetivo: realizar uma revisão da literatura sobre a influência da vaidade e do autocuidado para a qualidade de vida. Método: estudo de revisão em que as buscas foram realizadas nas bases de dados Scielo, Portal de Periódicos CAPES, LILACS, e Google Acadêmico. Foram selecionados artigos publicados entre 2010 e 2016, em periódicos nacionais e internacionais. As palavras chave utilizadas na pesquisa foram: estética; promoção da saúde; indústria cosmética; autoconceito; autoimagem; vaidade. Resultados: os artigos consultados mostraram que a aparência tem relação nos diversos aspectos do sucesso, poder humano, sendo a vaidade e autocuidado fatores importantes na construção da imagem. Considerações finais: devemos ser vistos não apenas como um corpo, mas como indivíduos providos de inteligência e sentimentos. Quando sabemos administrar nossa relação com a vaidade e autocuidado, preservando nossa saúde física e emocional, poderemos então ter um trunfo a mais no jogo das relações

    Depressão vascular no idoso: resposta ao tratamento antidepressivo associado a inibidor das colinesterases

    Get PDF
    CONTEXT: Among neuropsychiatric disorders caused by cerebrovascular factors, vascular depression is diagnosed in a small degree by general practitioners, causing morbid-mortality increase in elderly. CASE REPORT: That is a case of a 67 year-old-man with partial response after treatment with a Selective Serotonin Receptors Inhibitor, and severe autonomic adverse effects with other antidepressants. The addition of rivastigmine to citalopram resulted in a therapeutic success, with a reduction of 23 to 7 points on the Hamilton Depressive Scale (HAM-D). DISCUSSION: The result obtained brings new perspectives to the treatment of vascular depression, providing that randomized controlled trials with larger sample sizes confirm the positive effect of the addition of a cholinesterase inhibitor to antidepressants in the treatment of these patients.CONTEXTO: Entre os transtornos neuropsiquiátricos ocasionados por eventos cerebrovasculares, a depressão vascular é pouco diagnosticada por médicos não especialistas, causando aumento da morbimortalidade de pacientes idosos. CASO CLÍNICO: Trata-se de um paciente com 67 anos que apresentou resposta parcial a tratamento com inibidores da recaptura de serotonina e efeitos adversos autonômicos graves com outros antidepressivos. A adição de rivastigmina ao citalopram promoveu sucesso terapêutico, com redução de 23 para 7 pontos, na escala de Hamilton para depressão. DISCUSSÃO: O resultado obtido traz novas perspectivas para o tratamento da depressão vascular, sendo necessários ensaios clínicos controlados que evidenciem o benefício da adição dos inibidores das colinesterases aos antidepressivos no tratamento destes pacientes

    Efeitos fisiológicos decorrentes do exercício físico no organismo materno durante a gestação

    Get PDF
    Objetivo: identificar os benefícios fisiológicos que a prática de exercício físico pode proporcionar ao organismo materno, baseados em testes já realizados. Método: estudo de revisão de literatura, com buscas realizadas nas bases de dados Scielo, Portal de Periódicos Capes, LILACS e no Google Acadêmico. Foram selecionados 32 artigos publicados entre 1999 a 2014 inglês e português encontrados por meio das palavras-chave: efeitos fisiológicos do exercício físico; gestante; organismo materno. Resultados: os estudos demonstraram que o exercício físico durante a gestação pode melhorar o sistema cardiovascular, a circulação sanguínea, favorece uma melhor captação, transporte e utilização do oxigênio. Pode prevenir o surgimento da diabetes gestacional e reduzir a taxa de glicose. O exercício realizado na água é fisiologicamente mais apropriado para gestantes, pois no meio líquido, o corpo se livra naturalmente do excesso de água e sal. Considerações finais: os artigos selecionados mostram a importância da prática de atividade física, durante a gestação, para a promoção da saúde da mãe e da criança

    Modulation of the pharmacological effects of enzymatically-active PLA2 by BTL-2, an isolectin isolated from the Bryothamnion triquetrum red alga

    <p>Abstract</p> <p>Background</p> <p>An interaction between lectins from marine algae and PLA<sub>2 </sub>from rattlesnake was suggested some years ago. We, herein, studied the effects elicited by a small isolectin (BTL-2), isolated from <it>Bryothamnion triquetrum</it>, on the pharmacological and biological activities of a PLA<sub>2 </sub>isolated from rattlesnake venom (<it>Crotalus durissus cascavella</it>), to better understand the enzymatic and pharmacological mechanisms of the PLA<sub>2 </sub>and its complex.</p> <p>Results</p> <p>This PLA<sub>2 </sub>consisted of 122 amino acids (approximate molecular mass of 14 kDa), its pI was estimated to be 8.3, and its amino acid sequence shared a high degree of similarity with that of other neurotoxic and enzymatically-active PLA<sub>2</sub>s. BTL-2 had a molecular mass estimated in approximately 9 kDa and was characterized as a basic protein. In addition, BTL-2 did not exhibit any enzymatic activity.</p> <p>The PLA<sub>2 </sub>and BTL-2 formed a stable heterodimer with a molecular mass of approximately 24–26 kDa, estimated by molecular exclusion HPLC. In the presence of BTL-2, we observed a significant increase in PLA<sub>2 </sub>activity, 23% higher than that of PLA<sub>2 </sub>alone. BTL-2 demonstrated an inhibition of 98% in the growth of the Gram-positive bacterial strain, <it>Clavibacter michiganensis michiganensis </it>(Cmm), but only 9.8% inhibition of the Gram-negative bacterial strain, <it>Xanthomonas axonopodis </it>pv <it>passiflorae </it>(Xap). PLA<sub>2 </sub>decreased bacterial growth by 27.3% and 98.5% for Xap and Cmm, respectively, while incubating these two proteins with PLA<sub>2</sub>-BTL-2 inhibited their growths by 36.2% for Xap and 98.5% for Cmm.</p> <p>PLA<sub>2 </sub>significantly induced platelet aggregation in washed platelets, whereas BTL-2 did not induce significant platelet aggregation in any assay. However, BTL-2 significantly inhibited platelet aggregation induced by PLA<sub>2</sub>. In addition, PLA<sub>2 </sub>exhibited strong oedematogenic activity, which was decreased in the presence of BTL-2. BTL-2 alone did not induce oedema and did not decrease or abolish the oedema induced by the 48/80 compound.</p> <p>Conclusion</p> <p>The unexpected results observed for the PLA<sub>2</sub>-BTL-2 complex strongly suggest that the pharmacological activity of this PLA<sub>2 </sub>is not solely dependent on the presence of enzymatic activity, and that other pharmacological regions may also be involved. In addition, we describe for the first time an interaction between two different molecules, which form a stable complex with significant changes in their original biological action. This opens new possibilities for understanding the function and action of crude venom, an extremely complex mixture of different molecules.</p
