Creation of Artificial Ionospheric Layers Using High-Power HF Waves
We report the first evidence of artificial ionospheric plasmas reaching sufficient density to sustain interaction with a high-power HF pump beam produced by the 3.6 MW High-Frequency Active Auroral Program…

Preparing Students for Future Learning with Teachable Agents
One valuable goal of instructional technologies in K-12 education is to prepare students for future learning. Two classroom studies examined whether Teachable Agents (TA) achieves this goal.

Reduction of AlGaAs Heterostructure High-Index-Contrast Ridge Waveguide Scattering Loss By Sidewall Smoothing Through Oxygen-Enhanced Wet Thermal Oxidation
We demonstrate the efficacy of oxidation smoothing of sidewall roughness in high-index-contrast AlGaAs heterostructure ridge waveguides via oxygen-enhanced nonselective wet thermal oxidation for reducing scattering loss.

Synthesis and Tissue Distribution Studies of Acyloxyalkyl Prodrug Derivative of an Anti-HBV Dinucleotide
The preferential distribution of the dinucleotide 1 and its prodrug 2 into liver may be attributed to the presence of nucleoside phosphorothioate backbone because phosphorothioate oligonucleotides also reveal a similar…

Biomimetic Actinide Chelators: an Update on the Preclinical Development of the Orally Active Hydroxypyridonate Decorporation Agents 3,4,3-Li(1,2-HOPO) and 5-LIO(Me-3,2-HOPO)
A perspective on the preclinical development of two hydroxypyridonate actinide decorporation agents, 3,4,3-LI(1,2-HOPO) and 5-LIO(Me-3,2-HOPO), is presented. The chemical syntheses of both candidate compounds have been optimized for scale-up.
