Roadmap for implementation of genomics in healthcare: towards equity in access to genomics
As atividades do WP5 do projeto B1MG resultaram num documento intitulado "A Roadmap for genomics in healthcare", que se constitui como um guia e suporte para os sistemas de saĂșde que pretendam implementar a genĂłmica nos cuidados de saĂșde, facilitando a utilização do Maturity Level Model e providenciando acesso a guidelines e documentos desenvolvidos no Ăąmbito de outras iniciativas de medicina personalisada. Este poster apresenta o contexto, as atividades e os pontos essenciais que constituem o roadmap.Funding from the European Unionâs Horizon 2020 Research and Innovation programme under grant agreement No 951724N/
Non-Kaehler Heterotic String Compactifications with non-zero fluxes and constant dilaton
We construct new explicit compact supersymmetric valid solutions with
non-zero field strength, non-flat instanton and constant dilaton to the
heterotic equations of motion in dimension six. We present balanced Hermitian
structures on compact nilmanifolds in dimension six satisfying the heterotic
supersymmetry equations with non-zero flux, non-flat instanton and constant
dilaton which obey the three-form Bianchi identity with curvature term taken
with respect to either the Levi-Civita, the (+)-connection or the Chern
connection. Among them, all our solutions with respect to the (+)-connection on
the compact nilmanifold satisfy the heterotic equations of motion.Comment: LaTeX, 16 pp., no figures, new Theorem 1.1, references adde
Superconformal N=2, D=5 matter with and without actions
We investigate N=2, D=5 supersymmetry and matter-coupled supergravity
theories in a superconformal context. In a first stage we do not require the
existence of a Lagrangian. Under this assumption, we already find at the level
of rigid supersymmetry, i.e. before coupling to conformal supergravity, more
general matter couplings than have been considered in the literature. For
instance, we construct new vector-tensor multiplet couplings, theories with an
odd number of tensor multiplets, and hypermultiplets whose scalar manifold
geometry is not hyperkaehler.
Next, we construct rigid superconformal Lagrangians. This requires some extra
ingredients that are not available for all dynamical systems. However, for the
generalizations with tensor multiplets mentioned above, we find corresponding
new actions and scalar potentials. Finally, we extend the supersymmetry to
local superconformal symmetry, making use of the Weyl multiplet. Throughout the
paper, we will indicate the various geometrical concepts that arise, and as an
application we compute the non-vanishing components of the Ricci tensor of
hypercomplex group manifolds. Our results can be used as a starting point to
obtain more general matter-couplings to Poincare supergravity.Comment: 67 pages; v2: title of reference changed and small editing

From Mexico to Beijing: "Women in Development" Twenty Five Years On
During the past twenty five years the Women in Development (WID)approach has become an increasingly important issue in the literature on Third World development. WID issues and related activities have now been incorporated into the aid practice of most development agencies. This paper critically analyses the diverse and conflicting ideologies that have emerged in the WID literature since the early seventies
Factors influencing terrestriality in primates of the Americas and Madagascar
Among mammals, the order Primates is exceptional in having a high taxonomic richness in which the taxa are arboreal, semiterrestrial, or terrestrial. Although habitual terrestriality is pervasive among the apes and African and Asian monkeys (catarrhines), it is largely absent among monkeys of the Americas (platyrrhines), as well as galagos, lemurs, and lorises (strepsirrhines), which are mostly arboreal. Numerous ecological drivers and species-specific factors are suggested to set the conditions for an evolutionary shift from arboreality to terrestriality, and current environmental conditions may provide analogous scenarios to those transitional periods. Therefore, we investigated predominantly arboreal, diurnal primate genera from the Americas and Madagascar that lack fully terrestrial taxa, to determine whether ecological drivers (habitat canopy cover, predation risk, maximum temperature, precipitation, primate species richness, human population density, and distance to roads) or species-specific traits (body mass, group size, and degree of frugivory) associate with increased terrestriality. We collated 150,961 observation hours across 2,227 months from 47 species at 20 sites in Madagascar and 48 sites in the Americas. Multiple factors were associated with ground use in these otherwise arboreal species, including increased temperature, a decrease in canopy cover, a dietary shift away from frugivory, and larger group size. These factors mostly explain intraspecific differences in terrestriality. As humanity modifies habitats and causes climate change, our results suggest that species already inhabiting hot, sparsely canopied sites, and exhibiting more generalized diets, are more likely to shift toward greater ground use
