Nature. 2011 Sep 29;477(7366):570-3. doi: 10.1038/nature10389.

Delta Scuti (δSct) stars are opacity-driven pulsators with masses of 1.5-2.5 M⊙, their pulsations resulting from the varying ionization of helium. In less massive stars such as the Sun, convection transports mass and energy through the outer 30 per...

BACKGROUND: Paraoxonase-1, an organophosphorous-hydrolyzing enzyme, was shown to provide protection against organophosphates poisoning in vivo. In vitro findings suggest that the phytoalexin resveratrol can elevate paraoxonase-1 levels and thus may provide protection against organophosphate poisoning. This study was conducted...

The BREELIB nebulizer was developed for iloprost to reduce inhalation times for patients with pulmonary arterial hypertension (PAH). This multicenter, randomized, unblinded, four-part study compared inhalation time, pharmacokinetics, and acute tolerability of iloprost 5 µg at mouthpiece delivered via...

We demonstrate logic functionalities in a high-speed all-optical logic circuit based on differential Mach-Zehnder interferometers with semiconductor optical amplifiers as the nonlinear optical elements. The circuit, implemented by hybrid integration of the semiconductor optical amplifiers on a planar lightwave...

Assemblages of microscopic colloidal particles exhibit fascinating collective motion when energized by electric or magnetic fields. The behaviors range from coherent vortical motion to phase separation and dynamic self-assembly. Although colloidal systems are relatively simple, understanding their collective response,...

Enantiomeric Excess Sensitivity to Below One Percent by Using Femtosecond Photoelectron Circular Dichroism.

Photoelectron circular dichroism (PECD) is experimentally investigated with chiral specimens with varying amounts of enantiomeric excess (ee). As a prototype, we measure and analyze the photoelectron angular distribution from randomly oriented fenchone molecules in the gas phase that result...

Influence of electric potentials on friction of sliding contacts lubricated by an ionic liquid.

A chiral, nonracemic pentadentate pyridine bis(oxazoline) ligand forms unprecedented P-helical inorganic-organic hybrid polymers with cadmium halides. The one-dimensional chains consist of Lambda2-configured pentagonal-bipyramidal cadmium complexes with metal-centered chirality bridged by [CdX4]2- tetrahedra via shared halide atoms. In the solid...
