Abstract: View-based 3D shape classification is widely used in machine vision, information retrieval and other fields. However, there are two problems in current methods. First, current 3D shape ...

A rectangular prism net is a 2-dimensional pattern that can be folded to form a 3-dimensional rectangular prism. It's essentially an unfolded version of the prism, showing all its faces connected ...

Decades of research has viewed DNA as a sequence-based instruction manual; yet every cell in the body shares the same genes – so where is the language that writes the memory of cell identities?

Can you drill a hole in a cube that an identical cube could fall through? Prince Rupert of the Rhine first asked this question in the 17th century, and he soon found out the answer is yes. One can ...

After more than three centuries, a geometry problem that originated with a royal bet has been solved. Imagine you’re holding two equal-size dice. Is it possible to bore a tunnel through one die that’s ...

A rectangular prism, also known as a cuboid, is a three-dimensional geometrical shape with six flat sides. These sides are all rectangles and can have different lengths, widths, and heights. The ...

Concept design for a rectangular space telescope, modeled after the Diffractive Interfero Coronagraph Exoplanet Resolver (DICER), a notional infrared space observatory, and the James Webb Space ...

Abstract: In recent years, with the rapid growth number of multi-modal 3D shapes, it has become increasingly important to efficiently recognize a vast number of unlabeled multi-modal 3D shapes through ...

Once Tomorrow joins the DHV Magellan crew in Death Stranding 2, Rainy will periodically ask Sam for the answers to questions to help with the young woman’s education. There are only three of these, ...

Magenta rectangles, which angled and sharp-cornered geometric shapes which are cuboids and 3d rectangular prisms meshing each other, turning and spinning around with an endless movement. It has a ...
