By virtue of the stability of signatures and the high difficulty of imitation, handwriting signatures, as an important behavioral biometric trait, have been broadly adopted for authorization and identity verification.The emergence of consumer-level wrist-worn devices incorporating rich sensors has profoundly changed human-machine interactions, enab
The normal vector estimation of the large-scale scattered point cloud (LSSPC) plays an important role in point-based shape editing.However, the normal vector estimation for LSSPC cannot meet the great challenge of the sharp increase of the point cloud that is mainly attributed to its low computational efficiency.In this paper, a novel, fast method-
Background.For esthetic considerations in anterior regions, abutments with high-strength ceramics such as alumina and zirconia have been developed as substitutes for titanium abutments.The present study was designed to investigate the distribution of stress in prosthesis and bone components of an implant-supported FPD with different abutments by us

Leaf morphometrics are used frequently by several disciplines, including taxonomists, systematists, developmental biologists, morphologists, agronomists, and plant breeders to name just a few.Leaf shape is highly variable and can be used for identifying species or genotypes, developmental patterning within and among individuals, assessing plant hea
