In this paper we show that a 3D analogue for the first Hu moment invariant, originally introduced for planar shapes, is minimized by a sphere. By exploiting this fact we define a new compactness measure for 3D shapes. The new compactness measure indicates how much a given shape differs from a sphere, which is assumed to be the most compact 3D shape. The new(More)
The present study demonstrates the synthesis of water-soluble fluorescent calix[4]arenes (6 and 7) and its application in living cell imaging for Hg2+ detection at a low level. The synthesized fluorescent ligands 6 and 7 were characterized by 1H NMR technique. The fluorescent study showed both water soluble ligands were Hg2+ selective and follow(More)
