Quantitative analysis of brain MRI at the age of 6 months is difficult because of the limited contrast between white matter and gray matter. In this study, we use a dilated triplanar convolutional neural network in combination with a non-dilated 3D convolutional neural network for the segmentation of white matter, gray matter and cerebrospinal fluid in infant brain MR images, as provided by the...

ACKNOWLEDGEMENTS The authors would like to thank the enumerators for their help with data collection, all study participants, and Dennis Rentsch and Deborah Randall for their advice on the design of the survey. This paper originates in a research project " Hunting for Sustainability " supported by the European Commission under the 7 th Framework Programme for Research and Technological Developm...

At the University of Tennessee, The Grand Challenge Scholar program operates in conjunction with the Honors Engineering Leadership minor (HELM) and emphasizes leadership training as part of interdisciplinary coursework preparing engineering students to work at the boundaries of their profession with business, entrepreneurship, ethics, and human behavior. We have formed a partnership with the De...

A grand challenge of the 21 century cosmology is to accurately estimate the cosmological parameters of our Universe. A major approach in estimating the cosmological parameters is to use the large scale matter distribution of the Universe. Galaxy surveys provide the means to map out cosmic large-scale structure in three dimensions. Information about galaxy locations is typically summarized in a ...

State investments in center-based school readiness programs for preschoolers (pre-K), whether targeted for poor children or universally implemented, have expanded more rapidly than evaluations of their effects. Given the current interest and continuing expansion of state funded pre-K, it is especially important to be clear about the nature of the available evidence for the effectiveness of such...

Let D n;k denote the subspace arrangement formed by all linear subspaces in R n given by equations of the form k. Some important topological properties of such a subspace arrangement depend on the topology of its intersection lattice. In previous work on a larger class of subspace arrangements by Bjj orner & Sagan BS] the topology of the intersection lattice L(D n;k) = n;k turned out to be a pa...

Over recent decades, medical research has become mostly an 'applied' science which implicitly aims at steady progress by an accumulation of small improvements, each increment having a high probability of validity. Applied medical science is, therefore, a social system of communications for generating pre-publication peer-reviewed knowledge that is ready for implementation. However, the need for...

In French, regardless of stem regularity, inflectional verbal suffixes are extremely regular and paradigmatic. Considering the complexity of the French verbal system, we argue that all French verbs are polymorphemic forms that are decomposed during visual recognition independently of their stem regularity. We conducted a behavioral experiment in which we manipulated the surface and cumulative f...
