    Abstract: A near-to-eye display device and wearable apparatus are provided. The near-to-eye display device includes: pixel islands and micro-lenses in one-to-one correspondence with the pixel islands; wherein each pixel island emits light to a corresponding micro-lens so that the light reaches a predetermined viewing position after passing through the corresponding micro-lens. The near-to-eye display device further includes: super-lens units each including at least one super-lens; wherein the super-lens units are in one-to-one correspondence with the pixel islands; each super-lens unit is on a side of a corresponding pixel island proximal to the corresponding micro-lens, and an orthogonal projection of the super-lens unit on a plane where the corresponding pixel island is located covers the corresponding pixel island. The super-lens unit converges light, which is within a predetermined angle, emitted by the corresponding pixel island, to reduce a diffusion angle of the light emitted by the corresponding pixel island.

  • Publication number: 20240047011
    Abstract: Embodiments disclosed herein provide methods for identifying new CRISPR loci and effectors, as well as different CRISPR loci combinations found in various organisms. Class-II CRISPR systems contain single-gene effectors that have been engineered for transformative biological discovery and biomedical applications. Discovery of additional single-gene or multicomponent CRISPR effectors may enhance existing CRISPR applications, such as precision genome engineering. Comprehensive characterization of CRISPR-loci may identify novel functional roles of CRISPR loci enabling new tools for biomedicine and biological discovery. CRISPR loci have enormous feature complexity, but classification of CRISPR loci has been focused on a small fraction of highly abundant features. Increased genome sequencing has enhanced the sampling of this feature complexity.
