We report a draft sequence for the genome of domesticated silkworm (Bombyx mori), covering 90.9% all known genes. Our estimated gene count is 18,510, which exceeds 13,379 genes reported Drosophila melanogaster. Comparative analyses to fruitfly, mosquito, spider, and butterfly reveal both similarities differences in content.

Artistic style transfer aims to repaint the content image with learned artistic style. Existing methods can be divided into two categories: small model-based approaches and pre-trained large-scale approaches. Small preserve strucuture, but fail produce highly realistic stylized images introduce artifacts disharmonious patterns; Pre-trained generate struggle preserving structure. To address above issues, we propose ArtBank, a novel framework, while structure of images. Specifically,...
Plasmonic Fano resonance, enabled by the weak interaction between a bright super-radiant and subradiant resonance mode, not only is fundamentally interesting, but also exhibits potential applications ranging from extraordinary optical transmission to biosensing.

Enhancing the nonlinear frequency conversion efficiency at nanoscale is important for on-chip communication, information processing and sensing. Plasmonic nanostructures can significantly enhance signal due to localized surface plasmon (LSP) resonance, that is, electric field enhancements. Ideally, a double resonance occurs, in which both excitation harmonic wavelengths are enhanced, but this restricted by available modes. It has been recently shown thin films of epsilon-near-zero (ENZ)...
