Efficient Query Processing for SPARQL Federations with Replicated Fragments

Low reliability and availability of public SPARQL endpoints prevent real-world applications from exploiting all the potential of these querying infras-tructures. Fragmenting data on servers can improve data availability but degrades performance. Replicating fragments can offer new tradeoff between performance and availability. We propose FEDRA, a framework for querying Linked Data that takes advantage of client-side data replication, and performs a source selection algorithm that aims to reduce the number of selected public SPARQL endpoints, execution time, and intermediate results. FEDRA has been implemented on the state-of-the-art query engines ANAPSID and FedX, and empirically evaluated on a variety of real-world datasets

Responsabilidade civil do médico em face do consentimento informado

A evolução das ciências biomédicas e suas tecnologias aplicadas à área da saúde possibilitaram o surgimento de inúmeras novidades. Como por exemplo, a relação médico paciente alterada de tal modo que para o médico se eximir de uma eventual demanda judicial deve ser utilizado o “Termo de Consentimento Informado” que desempenha na maioria das vezes o alicerce principal ao médico com o propósito de não sofrer eventual punição, por ter apresentando expressamente o termo ao paciente. Dessa maneira, temos que descobrir quais são os principais fundamentos da responsabilidade civil médica em face do consentimento informado. Utiliza-se os julgados do Tribunal de Justiça do Distrito Federal e Territórios, juntamente com o Superior Tribunal de Justiça, onde é retratado as consequências da apresentação ou não do consentimento. Esse termo visa a aceitação do paciente a um determinado tratamento médico, é um instrumento para fortalecer a relação entre médico e paciente.The evolution of the biomedical sciences and their technologies applied to the health area have allowed the appearance of many innovations. As for example, the doctor-patient relationship altered in such a way that for the doctor to be exempt from a possible judicial demand should be used the "Informed Consent Term" that most of the time plays the main foundation to the doctor in order not to suffer punishment, for expressly presenting the term to the patient. In this way, we have to find out what are the main foundations of medical civil liability in the face of informed consent. Judgments of the Court of Federal District and Territories are used together with the Superior Court of Justice, where the consequences of the presentation or not of the consent are described. This term aims at the acceptance of the patient to a certain medical treatment, is an instrument to strengthen the relationship between doctor and patient

Fedra: Query Processing for SPARQL Federations with Divergence

Data replication and deployment of local SPARQL endpoints improve scalability and availability of public SPARQL endpoints, making the consumption of Linked Data a reality. This solution requires synchronization and specific query processing strategies to take advantage of replication. However, existing replication aware techniques in federations of SPARQL endpoints do not consider data dynamicity. We propose Fedra, an approach for querying federations of endpoints that benefits from replication. Participants in Fedra federations can copy fragments of data from several datasets, and describe them using provenance and views. These descriptions enable Fedra to reduce the number of selected endpoints while satisfying user divergence requirements. Experiments on real-world datasets suggest savings of up to three orders of magnitude

A novel scheme of multicarrier modulation with the discrete cosine transform

In this work, we derive a novel multicarrier modulation based on the Type-I even discrete cosine transform (DCT1e), which includes new procedures to carry out both the channel estimation and the signal reconstruction. By using a small number of training symbols, we achieve an accurate estimation of the channel's impulse response (CIR) using a novel mirror, replicate and add (MIRA) procedure. The proposed scheme does not require knowing the length of the CIR and is valid even in the presence of spectral nones. We provide the theoretical results that guarantee the validity of the developed technique. After the estimation process, the transmitted symbols are also reconstructed by means of the DCT1e using the same novel MIRA scheme. The conditions that ensure a perfect reconstruction in the absence of noise are also provided in this case. Numerical simulations illustrate the excellent behaviour of the proposed approach, both in terms of channel estimation and recovery of the transmitted information.Ministerio de Economía y Competitivida

SemLAV: Querying Deep Web and Linked Open Data with SPARQL

International audienceSemLAV allows to execute SPARQL queries against the Deep Web and Linked Open Data data sources. It implements the mediator-wrapper architecture based on view definitions over remote data sources. SPARQL queries are expressed using a mediator schema vocabulary, and SemLAV selects relevant data sources and rank them. The ranking strat-egy is designed to deliver results quickly based only on view definitions, i.e., no statistics, nor probing on sources are required. In this demonstra-tion, we validate the effectiveness of SemLAV approach with real data sources from social networks and Linked Open Data. We show in differ-ent setups that materializing only a subset of ranked relevant views is enough to deliver significant part of expected results

Dried orange juice waste as a source of bioactive compounds

[EN] Purpose The waste generated in the process of obtaining orange juice (J) may be used as a natural source of bioactive compounds, thus contributing to the profitability and sustainability of the process. To offer orange J as a dried matter would contribute to the integral valorisation of the J waste and also may expand the field of application. Design/methodology/approach To find out whether the JW matrix protects the bioactive compounds, the study compares the behaviour of the extracts of the compounds against drying with that resulting from drying the JW for further extraction. Dehydration was carried out at 25 or 50 C and gum Arabic (GA) and bamboo fibre (BF) were used as stabilising biopolymers (Bp). Vitamin C (VC) (L-ascorbic and L-dehydroascorbic acids [AA and DHAA, respectively]) and hesperidin (HES) were analysed before and after the drying. Findings The results suggest that to dry the JW gives a higher yield of bioactive compounds, which are also more stable, than when the extract is dried. Furthermore, both the higher temperature and the presence of the Bp favour the extraction of both VC and HES. In this way, all the waste from the orange J-processing industries is converted into a high-value product to be used for cosmeceutical or nutraceutical purposes and also as an ingredient for human food. Social implications The utilisation of organic waste for use in human food, but also in other sectors, is part of the new economic model that aims to do away with the concept of waste as people know it, focussing on a new paradigm in which each resource is a nutrient for nature, industry or society. Originality/value The results suggest that to dry the waste gives a higher yield of bioactive compounds, which are also more stable, than when the extract is dried. Furthermore, both the higher temperature and the presence of the Bp favour the extraction of both VC and HES. In that way, all the waste from the orange J-processing industries are converted into a high-value product to be used for cosmeceutical or nutraceutical purposes and also as an ingredient for human food.The authors thank the Ministerio de Economía, Industria y Competitividad and the Vicerrectorado de Investigación de la Universitat Politècnica de València for the financial support given through the Projects AGL 2017-89251-R (AEI/FEDER-UE) and (PAID-11-21), respectively.Galindo, RG.; Chis, MS.; Martínez-Navarrete, N.; Camacho Vidal, MM.

Urbanismo, política e pandemia na América Latina

This article introduces in a substantial way the dossier "Urbanism, politics and pandemic in Latin America" that brings together a series of articles that present postcards, signs, relevant data and indications of the impact of the pandemic in various cities, especially in Argentina and Brazil, from a comparative perspective. The topics that crosscut this dossier are those of governance, the public management policy of the pandemic, the administration of the health crisis and its impacts on health sectors and the most vulnerable populations in various types of cities, conflicts between federal, state, regional and municipal powers, in addition to the performance of different types of leadership. In addition to this introduction, the dossier has 5 articles: Di Virgilio and Perelman, on Buenos Aires; Torres, Travassos, Moreira and Fernandes, on São Paulo; Arantes and Galvão, on Salvador;  Gledhill, who comments upon and compares this first set of articles, expanding the analytical scope to include other Latin American countries;  and a final article by Marques and Garzón that closes the dossier with an article on health systems in Amazonian intermediate cities, the genocide of indigenous populations and the case of Manaus in the North of Brazil. The main conclusions reached by the authors are about the existence of an enormous process of spatial segregation and what can be called "environmental racism", especially in the case of Brazil. Among the common elements in the region is that peripheral and poorer areas were the most affected, although the discussion also covers other types of changes in urban life and impacts of the pandemic on the middle classes. The pandemic exposed various forms of militant resistance and resilience from below to face the crisis. Argentina showed a better management of the health crisis, but in the cases of Brazil, Mexico and other countries of the continent, the fragility of public policies for the management of the pandemic and their health systems was evident. All this resulted in the widening of existing inequalities. Paradoxically, the processes of urbanization produced two types of results: on the one hand, they expanded the living conditions of certain sectors of the population but for the majority sector they only brought deindustrialization, precariousness and gentrification. At the same time, there were new social mobilizations in countries such as Chile and Colombia reflected growing increase in dissatisfaction in the face of the pandemic and the neoliberal urban development model. Urgent measures are suggested to address the problems: the eradication of poverty, a revision of the urban planning model, spatial redistribution and an improvement in sociability and urban mobility to achieve inclusion and social justice. The dossier closes with a new article on the health system crisis in Amazonia, with special emphasis on the tragic case of the lack of oxygen in Manaus.Este articulo introduce de modo substancial al dossier «Urbanismo, política y pandemia en América Latina» que reúne una serie de artículos que presentan postales, señales, datos relevantes e indicios del impacto de la pandemia en diversas ciudades, sobre todo de Argentina y Brasil, desde una perspectiva comparativa.

Distinctive Signals in 1‐minute Observations of Overshooting Tops and Lightning Activity in a Severe Supercell Thunderstorm

This work examines a severe weather event that took place over central Argentina on 11 December 2018. The evolution of the storm from its initiation, rapid organization into a supercell, and eventual decay was analyzed with high-temporal resolution observations. This work provides insight into the spatio-temporal co-evolution of storm kinematics (updraft area and lifespan), cloud-top cooling rates, and lightning production that led to severe weather. The analyzed storm presented two convective periods with associated severe weather. An overall decrease in cloud-top local minima IR brightness temperature (MinIR) and lightning jump (LJ) preceded both periods. LJs provided the highest lead time to the occurrence of severe weather, with the ground-based lightning networks providing the maximum warning time of around 30 min. Lightning flash counts from the Geostationary Lightning Mapper (GLM) were underestimated when compared to detections from ground-based lightning networks. Among the possible reasons for GLM's lower detection efficiency were an optically dense medium located above lightning sources and the occurrence of flashes smaller than GLM's footprint. The minimum MinIR provided the shorter warning time to severe weather occurrence. However, the secondary minima in MinIR that preceded the absolute minima improved this warning time by more than 10 min. Trends in MinIR for time scales shorter than 6 min revealed shorter cycles of fast cooling and warming, which provided information about the lifecycle of updrafts within the storm. The advantages of using observations with high-temporal resolution to analyze the evolution and intensity of convective storms are discussed.Fil: Borque, Paloma Celina. University of Illinois.
