In this paper a new patch-based digital signature (DS) is proposed. The proposed approach similar to steganography methods hides the secure message in a host image. However, it uses a patch-based key to encode/decode the data like cryptography approaches. Both the host image and key patches are randomly initialized. The proposed approach consists of encoding and decoding algorithms. The encodin...

Vitiligo, an autoimmune disorder, is known to co-localize with other immunological disorders like lichen planus and psoriasis. However, there are no reports regarding the co-localization of an autoimmune disorder (vitiligo) and a developmental disorder (verrucous epidermal nevus). We hereby present a 10-month-old infant who was visited for white patches on the right buttock and adjoining antero...

We used retrogradely transported fluorescent tracers to study the development of projections from area 17 to area 18 in normal and monocularly deprived kittens. In newborn animals, cells in area 17 that were labeled from small, discrete injections in area 18 were concentrated around the retinotopically corresponding zone, but distributed with lower density over a very wide surrounding area. Hen...
