open access: yes, 2012
In a topological insulator (TI) the character of electron transport varies from insulating in the interior of the material to metallic near its surface.

Neutron-capture element abundances in the planetary nebula NGC 5315 from deep optical and near-infrared spectrophotometry

open access: yes, 2017
We analyze the chemical composition of the planetary nebula (PN) NGC 5315, through high-resolution (R = 40000) optical spectroscopy with UVES at the Very Large Telescope, and medium-resolution (R = 4800) near-infrared spectroscopy with FIRE at Magellan ...

Renormalization Group Invariants in the MSSM and Its Extensions

open access: yes, 2005
We derive one-loop renormalization group (RG) invariant observables and analyze their phenomenological implications in the MSSM and its \mu problem solving extensions, U(1)' model and NMSSM.

Variance inequalities for quadratic forms with applications

open access: yes, 2015
We obtain variance inequalities for quadratic forms of weakly dependent random variables with bounded fourth moments. We also discuss two application. Namely, we use these inequalities for deriving the limiting spectral distribution of a random matrix ...

arf3DS4: An Integrated Framework for Localization and Connectivity Analysis of fMRI Data

open access: yesJournal of Statistical Software, 2011
In standard fMRI analysis all voxels are tested in a massive univariate approach, that is, each voxel is tested independently. This requires stringent corrections for multiple comparisons to control the number of false positive tests (i.e., marking ...

Relative mortality improvements as a marker of socio-economic inequality across the developing world, 1990-2009 [PDF]

open access: yes
Using cross country regressions, this paper constructs a novel distance-to-frontier metric for tracking broad socio-onomic inequality (including access of the poor to health infrastructure) over time for individual countries.

User's guide: Programs for processing altimeter data over inland seas [PDF]

open access: yes
The programs described were developed to process GEODYN-formatted satellite altimeter data, and to apply the processed results to predict geoid undulations and gravity anomalies of inland sea areas.
