Light-field microscopy (LFM) is a type of all-optical imaging system that is able to capture 4D geometric information of light rays and can reconstruct a 3D model from a single snapshot. In this paper ...

A four-dimensional (4D) geometrically-shaped constellation with low-density paritycheck codes is investigated to analyse the sensitivity improvements from 4D geometric shaping. Numerical results show ...

An unusual animal hoarding story in Farmington Hills involves dozens of cats staying with their owner in a single motel room.

A new 4D geometric code has also been revealed, and the abstract from Cornell University, mentioned in this blog post: https://lnkd.in/gy6F8yVM, is a valuable reference.

Students will love learning about Geometry, Area and 3D Shapes in this interactive and fun 3D Nets Geometry activity.

Our theory explains how a surface representation, that is, a topological labeling of contiguous surface components together with a geometric description of their shapes and positions, can be extracted ...
