Testing Slope Homogeneity in Large Panels
Social Science Research Network, 2005 This paper proposes a modi?ed version of Swamy’s test of slope homogeneity for panel data models where the cross section dimension (N) could be large relative to the time series dimension (T).

P wave dispersion and maximum P wave duration are associated with renal outcomes in chronic kidney disease. [PDF]
PLoS ONE, 2014 P wave parameters measured by 12-lead electrocardiogram (ECG) are commonly used as a noninvasive tool to evaluate left atrial enlargement. This study was designed to assess whether P wave parameters were associated with renal outcomes in chronic kidney ...

Negative plasmon dispersion in 2H-NbS2 beyond the charge-density-wave interpretation
New Journal of Physics, 2016 We examine the experimental and theoretical electron-energy loss spectra in 2 H - ${\mathrm{Cu}}_{0.2}$ NbS _2 and find that the 1 eV plasmon in this material does not exhibit the regular positive quadratic plasmon dispersion that would be expected for a

Interactions between Activation and Repolarization Restitution Properties in the Intact Human Heart: In-Vivo Whole-Heart Data and Mathematical Description. [PDF]
PLoS ONE, 2016 BACKGROUND:The restitution of the action potential duration (APDR) and conduction velocity (CVR) are mechanisms whereby cardiac excitation and repolarization adapt to changes in heart rate. They modulate the vulnerability to dangerous arrhythmia, but the

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...
