We provide a theoretical description of light scattering by spherical particle the permittivity which is modulated in time at twice frequency incident light. Such acts as finite-sized photonic crystal and, despite its subwavelength spatial extent, can host optical parametric amplification. Conditions Mie resonances sphere are derived. show that time-modulated materials route to tailor direction...

BACKGROUND Global analysis of the genome, transcriptome, and proteome is facilitated by the recent development of tools for large-scale, highly parallel analysis. We describe a novel nucleic acid amplification system that generates products by several methods. 3'-Ribo-SPIA primes cDNA synthesis at the 3' polyA tail, and whole transcript (WT)-Ribo-SPIA primes cDNA synthesis across the full lengt...
