Fit-ligand is a computational algorithm that enables accurate modeling of multiple conformational states of ligands in X-ray crystallography and cryo-electron microscopy (cryo-EM).

A novel higher-dimensional definition for Costas arrays is introduced. This definition works for arbitrary dimensions and avoids some limitations of previous definitions. Some non-existence results ...

In this letter, a near-field focused array antenna is applied to two-dimensional microwave imaging, which steers its focus on the designed focal plane by changing the operating frequency and by phase ...
