Imaging high-dimensional spatial entanglement with a camera

The light produced by parametric down-conversion shows strong spatial entanglement that leads to violations of EPR criteria for separability. Historically, such studies have been performed by scanning a single-element, single-photon detector across a detection plane. Here we show that modern electron-multiplying charge-coupled device cameras can measure correlations in both position and momentum across a multi-pixel field of view. This capability allows us to observe entanglement of around 2,500 spatial states and demonstrate Einstein-Podolsky-Rosen type correlations by more than two orders of magnitude. More generally, our work shows that cameras can lead to important new capabilities in quantum optics and quantum information science.Comment: 5 pages, 4 figure

O ethos e o pathos na sala de parto

RESUMO Objetivo Compreender o ethos e o pathos presentes nos discursos de mulheres parturientes e profissionais de saúde no contexto da sala de parto. Método Pesquisa qualitativa do tipo interpretativa. Utilizou-se o método da Análise do Discurso. Participaram das entrevistas 36 mulheres e 24 profissionais de saúde de maternidades do interior de Minas Gerais. Resultados Os discursos sinalizam a concepção que as mulheres têm do parto, centrada no olhar do outro e nas suas representações; as dificuldades das enfermeiras para operacionalizar o cuidado e construir uma imagem profissional autônoma. O discurso médico enfatiza a especialidade, a capacidade de intervir em situações de risco e as mudanças no status da profissão. Conclusões A construção do ethos de médicos e enfermeiros é fundamental para o delineamento de campos de saberes mais flexíveis e parauma atuação profissional condizente com os seus papéis e comprometida com os preceitos éticos e legais do cuidado obstétrico

A methodology for parameter estimation in seaweed productivity modelling

This paper presents a combined approach for parameter estimation in models of primary production. The focus is on gross primary production and nutrient assimilation by seaweeds. A database of productivity determinations, biomass and mortality measurements and nutrient uptake rates obtained over one year for Gelidium sesquipedale in the Atlantic Ocean off Portugal has been used. Annual productivity was estimated by harvesting methods, and empirical relationships using mortality/ wave energy and respiration rates have been derived to correct for losses and to convert the estimates to gross production. In situ determinations of productivity have been combined with data on the light climate (radiation periods, intensity, mean turbidity) to give daily and annual productivity estimates. The theoretical nutrient uptake calculated using a 'Redfield ratio' approach and determinations of in situ N and P consumption by the algae during incubation periods have also been compared. The results of the biomass difference and incubation approaches are discussed in order to assess the utility of coefficients determined in situ for parameter estimation in seaweed production models

The fourth wave of Portuguese emigration: Austerity policies, European peripheries and postcolonial continuities

Little is known about emigration in European countries. Migratory pressure and the recent refugee crisis have helped keep academic attention over the last few decades focused on immigration, asylum and integration in Europe. However, these dynamics promoting entries into European countries coexist with other fair-ly significant dynamics promoting departures from these countries. The sovereign debt crisis coupled with austerity policies that asymmetrically affected Europe’s peripheral countries have increased emigration in various European countries. Our book aims to counter the invisibility of emigration from European countries in the literature by examining the particularities of the Portuguese case. In methodological terms, the book compiles the work of authors from different academic backgrounds who have conducted empirical research using a wide vari-ety of extensive and intensive methods. It is argued that when analysing recent Portuguese emigration it is important to examine in further detail: i) the impact of the 2008 economic and financial crisis and the austerity policies that followed in its wake; ii) south-north emigration in Europe; iii) north-south emigration outside Europe and post-colonial continuities; iv) the importance of reassessing the exist-ing model of Southern European migration; v) highly skilled and less skilled mi-gration; and finally, vi) emigrants’ and their descendants’ identities.info:eu-repo/semantics/publishedVersio

Circulation of Different Lineages of Dengue Virus 2, Genotype American/Asian in Brazil: Dynamics and Molecular and Phylogenetic Characterization

The American/Asian genotype of Dengue virus type 2 (DENV-2) was introduced into the Americas in the 80′s. Although there is no data showing when this genotype was first introduced into Brazil, it was first detected in Brazil in 1990. After which the virus spread throughout the country and major epidemics occurred in 1998, 2007/08 and 2010. In this study we sequenced 12 DENV-2 genomes obtained from serum samples of patients with dengue fever residing in São José do Rio Preto, São Paulo (SJRP/SP), Brazil, in 2008. The whole open reading frame or envelope sequences were used to perform phylogenetic, phylogeographic and evolutionary analyses. Isolates from SJRP/SP were grouped within one lineage (BR3) close to isolates from Rio de Janeiro, Brazil. Isolates from SJRP were probably introduced there at least in 2007, prior to its detection in the 2008 outbreak. DENV-2 circulation in Brazil is characterized by the introduction, displacement and circulation of three well-defined lineages in different times, most probably from the Caribbean. Thirty-seven unique amino acid substitutions were observed among the lineages, including seven amino acid differences in domains I to III of the envelope protein. Moreover, we dated here, for the first time, the introduction of American/Asian genotype into Brazil (lineage BR1) to 1988/89, followed by the introduction of lineages BR2 (1998–2000) and BR3 (2003–05). Our results show a delay between the introduction and detection of DENV-2 lineages in Brazil, reinforcing the importance and need for surveillance programs to detect and trace the evolution of these viruses. Additionally, Brazilian DENV-2 differed in genetic diversity, date of introduction and geographic origin and distribution in Brazil, and these are important factors for the evolution, dynamics and control of dengue.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq Grant )Fundação de Amparo à Pesquisa do Estado de São PauloFundação de Amparo à Pesquisa do Estado de Minas Gerais (FAPEMIG grant
