Traditional 1D bar codes (with printed bars and spaces) are giving way to 2D bar codes that also include dots, hexagons, and even colors to encode more data. Bar-code scanners read 1D bar codes.

These 2D images permitted computational reconstruction of the 3D structure of the octahedron origami ... We prescribe these 1D and 2D arrays by encoding the octahedron to carry two-fold ...

This figure depicts the synthesis of metallic 1D mirror twin boundaries through Van der Waals epitaxial growth (top) and the large-area 2D semiconductor integrated circuit constructed based on ...

AbstractBolton & Schlegel presented a promising deconvolution method to extract one-dimensional (1D) spectra from a two-dimensional (2D) optical fiber spectral CCD (charge-coupled device) image. The ...
