A Multilingual Study of Compressive Cross-Language Text Summarization

Cross-Language Text Summarization (CLTS) generates summaries in a language different from the language of the source documents. Recent methods use information from both languages to generate summaries with the most informative sentences. However, these methods have performance that can vary according to languages, which can reduce the quality of summaries. In this paper, we propose a compressive framework to generate cross-language summaries. In order to analyze performance and especially stability, we tested our system and extractive baselines on a dataset available in four languages (English, French, Portuguese, and Spanish) to generate English and French summaries. An automatic evaluation showed that our method outperformed extractive state-of-art CLTS methods with better and more stable ROUGE scores for all languages

Emphasis on Mathematical Modeling: The Problems of Contour Values in Calculating the Deflection of a Beam

Mathematical Modeling has played a fundamental role in the process of teaching and learning mathematics at the various levels of education. The great challenge of today\u27s education is to create means to minimize the distance between the relations of mathematical theory and practical models of everyday life. This work aimed to treat the study of Ordinary Differential Equations through a very usual model of civil construction. Often, students of Mathematics Degree develop skills to understand the abstractions of the vast theory associated with the areas of mathematics, but without being able to exemplify and / or correlate with everyday models

Acessos de mandioca açucarada coletados no Nordeste paraense possuem o mesmo genótipo detectado por marcadores microssatélites.

A mandioca é encontrada na região Norte do Brasil e é usada como fonte de subsistência para muitas famílias. A mandioca açucarada ou mandiocaba, é um tipo de mandioca que armazena em suas raízes, além do amido, açúcares livres como reservas. Atualmente, vêm recebendo destaque pelo seu potencial para uso na fabricação de álcool combustível, devido ao acúmulo de glicose que pode ser convertida em etanol diretamente. Foi realizado teste para avaliar a diversidade genética de acessos de mandiocas açucaradas coletadas em diferentes locais do estado do Pará mantidos no banco de germoplasma da Embrapa Amazônia Oriental. Foi realizada a genotipagem molecular de nove acessos de mandioca açucarada e um acesso de mandioca brava com marcadores microssatélites. Para isso, foram utilizados 13 primers microssatélites e a corrida dos produtos amplificados foi realizada em géis de poliacrilamida 6%. Após a análise dos géis, foi verificado que todas as nove amostras de mandioca açucarada possuíam o mesmo genótipo, sendo verificada baixa variabilidade genética para esse grupo de mandiocas

Modeling Energy Communities with Collective Photovoltaic Self-Consumption: Synergies between a Small City and a Winery in Portugal

The recently approved regulation on Energy Communities in Europe is paving the way for new collective forms of energy consumption and production, mainly based on photovoltaics. However, energy modeling approaches that can adequately evaluate the impact of these new regulations on energy community configurations are still lacking, particularly with regards to the grid tariffs imposed on collective systems. Thus, the present work models three different energy community configurations sustained on collective photovoltaics self-consumption for a small city in southern Portugal. This energy community, which integrates the city consumers and a local winery, was modeled using the Python-based Calliope framework. Using real electricity demand data from power transformers and an actual winery, the techno-economic feasibility of each configuration was assessed. Results show that all collective arrangements can promote a higher penetration of photovoltaic capacity (up to 23%) and a modest reduction in the overall cost of electricity (up to 8%). However, there are clear trade-offs between the different pathways: more centralized configurations have 53% lower installation costs but are more sensitive to grid use costs (which can represent up to 74% of the total system costs). Moreover, key actor’s individual self-consumption rate may decrease by 10% in order to benefit the energy community as a whole.info:eu-repo/semantics/publishedVersio

Location of R&D activities by vertical multinationals over asymmetric countries

This paper deals with the location of R&D by vertical multinational firms. By taking the colocation of laboratories and productive plants as a benchmark, we can see that the spatial separation of both emerges under two conditions – high intensity of R&D spillovers and strong size asymmetry between countries. The latter condition is effective since it is related with a rising international inequality of wages. If the spatial separation of R&D and manufacturing takes place, headquarters services (namely R&D units) will be likely located in the smaller country. The converse pattern, where laboratories are place in the larger country, may arise if production is high-tech and the localized externalities of research activity are strong. Hence, this article confirms the main results of the literature on this topic but in the context of a different framework which allows us to tackle two usually disregarded topics: the transfer cost of technology; and the direct engagement of industrial workers in R&D spillovers. These aspects are dealt with by presupposing that, in addition to a “technological” externality among researchers, there is an “educational” externality exerted by researchers upon neighbouring industrial workers. When a country loses its laboratories, the inhabitants become intellectually “impoverished” and their labour starts to have a lesser efficiency.info:eu-repo/semantics/publishedVersio

Item response theory analysis of the recoded Internet Gaming Disorder Scale-Short-Form (IGDS9-SF)

Based on the nine criteria for Internet gaming disorder (IGD) in DSM-5, the Internet Gaming Disorder Scale 9-Short Form (IGDS9-SF; Pontes and Griffiths 2015) is the most widely used questionnaire for assessing IGD. The present study examined support for the unidimensional factor structure of the instrument, with a group of 868 adolescent and adult gamers from the USA, with criteria recoded as present or absent. The two-parameter logistic model (2PLM) was used to examine the item response theory properties of the criteria included in the measure. Confirmatory factor analysis supported the one-factor model. The 2PLM analysis indicated that all the criteria were strong discriminators of high and low latent IGD. Furthermore, the items measured more of the GAD dimension and with more precision from around +2 SD from the mean trait level. The implications of the findings for interpreting the IGDS9-SF scores for clinical practice are discussed

An overview of COVID-19 infection in dental practices - a questionnaire survey

Dental nurses and practitioners are at high risk of exposure to COVID-19 due to physical proximity and exposure to body fluids during treatment. Dental practices have implemented multiple protective protocols to decrease COVID-19 transmission; however, it is difficult to evaluate how effective these measures are, as there is limited data on COVID-19 in dental practices. To evaluate COVID-19 infection rates among dentists, dental staff, and patients in different countries through an online survey, with a primary focus on South Africa (SA). Cross-sectional online survey. One hundred fifty-four participants from 52 countries answered the survey, 48.6% (n=561) from SA. COVID-19 infections were reported in 18.2% (n=210) of dental practices. Only 1.1% regarded the practice as the source of infection for dentists and staff who got infected. In total, 13.9% (n=160) treated COVID-19 patients. SA presented a higher infection rate (19% vs 13%, p=0.04) and more frequent treatment of COVID-19 patients than the other countries combined (17% vs 11%, p=0.006). These findings support the need to maintain strict infection control measures to decrease transmission of SARSCoV-2 during the delivery of oral care

Characterization of microinjection moulded composites of polyamide 6 and carbon nanotubes

Microinjection molding is a powerful technology in micro-manufacture, providing millimeter scale parts at large scale production rate. In order to produce homogeneous composite parts, good dispersion of the nanoreinforcement in the polymer matrix is required. In the present work the carbon nanotube (CNT) reinforcement was dispersed in polyamide 6 (PA6) using a mini twin-screw extruder. Nanocomposites were prepared with different compositions (1% and 4,5%) of pure CNT (p-CNT) and functionalized CNT (f-CNT).Fundação para a Ciência e Tecnologi

Microinjection molding of polyamide 6/carbon nanotube composites

Microinjection molding of polymer composites with carbon nanotubes (CNT) requires previous production of the nanocomposites, often by melt extrusion. Each processing step has a thermo-mechanical effect on the polymer melt, conveying different properties to the final product. In this work, polyamide 6 and its composites with pristine and functionalized CNT (f-CNT) were processed by a mini twin-screw extrusion, followed by microinjection molding. The morphology induced on the polymer by each process was analyzed by differential scanning calorimetry and wide angle X-ray diffraction. Calorimetric analysis showed a secondary crystallization for the microinjected materials, absent for the extruded materials. The characterization of microinjected polyamide 6 by X-ray diffraction revealed a large contribution of the c phase to the total crystallinity, mainly in the skin region, while the nanocomposites and extruded materials were characterized by a larger contribution of the a phase. Functionalization of CNT did not affect significantly the polymer morphology compared to composites with pristine CNT.The authors acknowledge Fundacao para a Ciencia e Tecnologia for project PEst-C/CTM/LA0025/2013 (Strategic Project - LA 25 - 2013-2014), and for PhD grant for T.
