In this paper, the spherical-coordinate finite-difference time-domain method is applied to numerical analysis of phased array of monopoles distributed over a sphere. Outer boundary of the given ...

Point cloud denoising is crucial for 3D point clouds. This paper improves a multi-patch collaborative denoising method based on local frames, adopting a spherical coordinate method on the basis of the ...

The camera position on the sphere can be parameterized by two angles Theta and Phi and by the distance from center R. This approach is called the spherical coordinates.

While astronomers expect many supernova remnants remain to be discovered, the fact that Teleios was spotted at all “is pure luck,” Filipović says. Had it been located closer to the galactic plane, ...

Whole-mount 3D imaging at the cellular scale is a powerful tool for exploring complex processes during morphogenesis. In organoids, it allows examining tissue architecture, cell types, and morphology ...
