Abstract This study quantifies the contributions of tropical sea surface temperature (SST) variations during boreal warm season to interannual-to-decadal variability in cyclone genesis frequency (TCGF) over Northern Hemisphere ocean basins. The first seven leading modes SST are found affect basinwide TCGF one or more basins, and related canonical El Niño–Southern Oscillation (ENSO), global warm...

The Dawn Framing Camera (FC) has imaged the northern hemisphere of the Asteroid (4) Vesta at high spatial resolution and coverage. This study represents the first investigation of the overall geology of the northern hemisphere (22–90 N, quadrangles Av-1, 2, 3, 4 and 5) using these unique Dawn mission observations. We have compiled a morphologic map and performed crater size–frequency distributi...

For the entire ion energy range observed at Europa, we calculate spatially resolved maps of surface sputtering rates H2O, O2, and H2 from impacts by magnetospheric ions. We use perturbed electromagnetic fields a hybrid model Europa’s plasma interaction, along with particle-tracing tool, to trajectories ions impinging onto their resultant yields. examine how distribution depends on field perturb...

the usage and production of polychlorinated biphenyls (pcbs) was banned in argentina in2002, approximately twenty to thirty years later than in other countries. a total of 29 sediment samples (upto 14 m deep) were analyzed for a mix of seven individual pcbs in a time series for over more than one year in twelve selected locations, including harbors, recreational docks and several industrialized...

We have developed a fast and reliable pipeline to automatically parcellate the cortical surface into sub-regions. The pipeline can be used to study brain changes associated with psychiatric and neurological disorders. First, a genus zero cortical surface for one hemisphere is generated from the magnetic resonance images at the parametric boundary of the white matter and the gray matter. Second,...

The right cerebral hemisphere may be relatively specialized for parsing simple visual stimuli according to default rules, such as the Gestalt laws of perceptual organization, whereas the left cerebral hemisphere may be relatively specialized for overriding such default rules. We extend this model to 'semantically rich domains' by performing a divided-visual-field experiment on 16 chessmasters. ...

Introduction Due to structural characteristics of the visual pathways, stimuli that are presented in the right half of the visual field (RVF) are initially projected to the left cerebral hemisphere, while those presented in the left half of the visual field (LVF) are projected to the right cerebral hemisphere. This anatomical feature has frequently been taken to support the notion that the well...

[1] Surface emissions of SF6 are closely tied to human activity and thus fairly well known. They therefore can and have been used to evaluate tropospheric transport predicted by models. A range of new atmospheric SF6 data permit us to expand on earlier studies. The purpose of this first of two papers is to characterize known and new transport constraints provided by the data and to use them to ...
