F.Single He nanodroplets doped with Xe atoms are studied via ultrafast coherent x-ray diffraction imaging. The diffraction images show that rotating He nanodroplets about 200 nm in diameter contain a small number of symmetrically arranged quantum vortices decorated with Xe clusters. Unexpected large distances of the vortices from the droplet center (?0.7-0.8 droplet radii) are explained by a significant contribution of the Xe dopants to the total angular momentum of the droplets and a stabilization of widely spaced vortex configurations by the trapped Xe clusters. © 2016 American Physical Society

Communication: X-ray coherent diffractive imaging by immersion in nanodroplets

Communication: X-ray coherent diffractive imaging by immersion in nanodroplets. Structural Dynamics, 2(5), 9. doi:10.1063/1.4933297Lensless x-ray microscopy requires the recovery of the phase of the radiation scattered from a specimen. Here, we demonstrate a de novo phase retrieval technique by encapsulating an object in a superfluid helium nanodroplet, which provides both a physical support and an approximate scattering phase for the iterative image reconstruction. The technique is robust, fast-converging, and yields the complex density of the immersed object. Images of xenon clusters embedded in superfluid helium droplets reveal transient configurations of quantum vortices in this fragile system. (C) 2015 Author(s).

Meteorio : um estudo dos primeiros passos da detecção de meteoros por alunos brasileiros de ensino médio via aprendizagem significativa

A inserção da Física Moderna no programa de Ensino Médio é uma questão bastante presente na pesquisa atual em ensino de Física. Nessa perspectiva, o projeto MeteoRio apresenta-se como um caminho possível para a introdução, em nossas escolas, de temas de pesquisa de ponta em ciência. Ele tem por objetivo detectar meteoros e, futuramente, raios cósmicos em escolas brasileiras de Ensino Médio com a participação de alunos, professores e pesquisadores. O presente trabalho descreve o início da implementação do MeteoRio no Colégio de Aplicação da Universidade Federal do Rio de Janeiro e procura analisar as atividades desenvolvidas à luz da teoria da aprendizagem significativa de Ausubel. Pretendemos também verificar se aprender ciência fazendo ciência contribui para uma construção efetiva do conhecimento

How important is agriculture and familiar agriculture agribusiness for Brazil and its states: an interregional input-output approach

The aim of this paper is estimate how important is agriculture and familiar agriculture agribusiness for Brazil and its states. To do so, the GDP for the agribusiness of these complexes is estimated for Brazil and for its 27 states. The estimation is based on an interregional input-output system constructed for the Brazilian economy. The agribusiness takes into consideration the relations between the agriculture production and the other sectors in the economy (inputs for production, industry, transportation, distribution, and commercialization). The importance of the agribusiness can be evidence for it’s share of about 30% in the total Brazilian GDP, but regional differences will make this average oscillates between 4% and 79% in the Brazilian states. Another distinction will be made between small familiar production and large scale production that will vary according to the product and the state. Some relation between land distribution and the type of agriculture will also be made

Ancestral diversity improves discovery and fine-mapping of genetic loci for anthropometric traits - the Hispanic/Latino Anthropometry Consortium

Hispanic/Latinos have been underrepresented in genome-wide association studies (GWAS) for anthropometric traits despite their notable anthropometric variability, ancestry proportions, and high burden of growth stunting and overweight/obesity. To address this knowledge gap, we analyzed densely-imputed genetic data in a sample of Hispanic/Latino adults to identify and fine-map genetic variants associated with body mass index (BMI), height, and BMI-adjusted waist-to-hip ratio (WHRadjBMI). We conducted a GWAS of 18 studies/consortia as part of the Hispanic/Latino Anthropometry (HISLA) Consortium (Stage 1, n=59,771) and generalized our findings in 9 additional studies (HISLA Stage 2, n=10,538). We conducted a trans-ancestral GWAS with summary statistics from HISLA Stage 1 and existing consortia of European and African ancestries. In our HISLA Stage 1+2 analyses, we discovered one BMI locus, as well as two BMI signals and another height signal each within established anthropometric loci. In our trans-ancestral meta-analysis, we discovered three BMI loci, one height locus, and one WHRadjBMI locus. We also identified three secondary signals for BMI, 28 for height, and two for WHRadjBMI in established loci. We show that 336 known BMI, 1,177 known height, and 143 known WHRadjBMI (combined) SNPs demonstrated suggestive transferability (nominal significance and effect estimate directional consistency) in Hispanic/Latino adults. Of these, 36 BMI, 124 height, and 11 WHRadjBMI SNPs were significant after trait-specific Bonferroni correction. Trans-ancestral meta-analysis of the three ancestries showed a small-to-moderate impact of uncorrected population stratification on the resulting effect size estimates. Our findings demonstrate that future studies may also benefit from leveraging diverse ancestries and differences in linkage disequilibrium patterns to discover novel loci and additional signals with less residual population stratification

Advances on Medium Access Control for Cognitive Radio Networks

Over the last two decades, wireless communications have gained more and more importance in our everyday life. The rapidly growing of mobile wireless access services, together with an outdated fixed spectrum access policy is speeding up the need for more radio spectrum, a finite resource that is the basis of wireless communications. To increase the spectrum utilization, and therefore its usage efficiency, a big effort has been employed to develop and improve novel and alternative spectrum management policies, often referred to as Dynamic Spectrum Access (DSA). In DSA schemes, one piece of spectrum can be allocated to one or more users, which are called Primary Users (PUs) or licensed users, using the traditional fixed spectrum access policy. However, these users do not own the exclusivity of accessing the licensed channel, although they have higher priority in using it. But when the licensed channel is not being used by the PUs, the channel is vacant, leading to a spectrum underutilization. In this case, other users, denominated as Secondary Users (SUs) or unlicensed users, can dynamically access to the temporary vacant channel without interfering with PUs, hence improving the spectrum efficiency. The aforementioned characteristics of SUs, and therefore the peculiar characteristics of Cognitive Radio Networks (CRNs) distinguish them from the traditional wireless networks. Thus, traditional cross-layered Physical (PHY)-Medium Access Control (MAC) architectures become unsuitable for this new type of networks. In CRNs, the PHY layer should be responsible to performspectrum sensing tasks, enabling Cognitive Radio (CR) users to identify the spectrum holes, and also to reconfigure and optimize the transceiver based on the results acquired from the environment. Regarding the MAC sublayer, it should be capable to choose between the spectrum sensing and the spectrum access. The sensing/access coordination should be based on a tradeoff between sensing opportunities requirement and spectrum access requirements. This chapter reviews the most popular decentralized CR MAC protocols already proposed for CR networks. We start with a brief overview describing the basics of the CR principles. Then, we describe the main features that characterize the different CR MAC protocols, emphasizing their strengths and weaknesses. A new taxonomy that classifies the described protocols in several dimensions is also proposed. Finally, we point out open research problems regarding the design of distributed CR MAC protocols
