Violência contra crianças na cidade de Ribeirão Preto, São Paulo, Brasil: a prevalência dos maus-tratos calculada com base em informações do setor educacional Violence against children in the city of Ribeirão Preto, São Paulo State, Brazil: child abuse prevalence estimated from school system data

open access: yesCadernos de Saúde Pública, 2009
Os números oficiais dos maus-tratos infantis não correspondem à realidade, pois muitos casos não são notificados. No presente estudo, buscou-se estimar a prevalência em crianças de 0 a 10 anos matriculadas em estabelecimentos educacionais da rede pública

Co-Regularized Deep Representations for Video Summarization

open access: yes, 2015
Compact keyframe-based video summaries are a popular way of generating viewership on video sharing platforms. Yet, creating relevant and compelling summaries for arbitrarily long videos with a small number of keyframes is a challenging task. We propose a

Seismo‐Acoustic Detection and Localization of Iceberg Collapse in Atka Bay, Antarctica

open access: yesGeophysical Research Letters
On 12 January 2022, an iceberg collapsed at the edge of frozen Atka Bay, Antarctica. The event generated seismic, hydroacoustic, and atmospheric infrasound waves recorded by a local network comprising land‐ and iceshelf‐based seismometers, an underwater ...

The power of phylogenetic approaches to detect horizontally transferred genes

open access: yesBMC Evolutionary Biology, 2007
Background Horizontal gene transfer plays an important role in evolution because it sometimes allows recipient lineages to adapt to new ecological niches. High genes transfer frequencies were inferred for prokaryotic and early eukaryotic evolution.

Southern Ocean warming: Increase in basal melting and grounded ice loss [PDF]

open access: yes, 2013
We apply a global finite element sea ice/ice shelf/ocean model (FESOM) to the Antarctic marginal seas to analyze projections of ice shelf basal melting in a warmer climate.

Modelling stellar populations at high redshift

open access: yes, 2011
Stellar populations carry information about the formation of galaxies and their evolution up to the present epoch. A wealth of observational data are available nowadays, which are analysed with stellar population models in order to obtain key properties ...

COMPTEL observations of the blazars 3C 454.3 and CTA 102 [PDF]

open access: yes, 2001
We have analyzed the two blazars of 3C 454.3 and CTA 102 using all available COMPTEL data from 1991 to 1999. In the 10–30 MeV band, emission from the general direction of the sources is found at the 4σ-level, being consistent with contributions from both
