Coagulation factor VII covalently coupled to Sepharose proved to be an effective binding ligand for human tissue factor apoprotein, the specific cofactor of factor VII for the activation of factor X and IX. This interaction is completely calcium-dependent and the calcium ions cannot be replaced by magnesium or barium ions. The binding of the apoprotein to(More)
We present the results of an investigation that compares matching SIFT local image features that have been extracted from a software-based retina model under two different forms of retina geometry, log(z) and log(z + α). Our retinas are sampled by receptive fields (RF) which are organized at a high density in the central foveal region of the retina(More)
Tissue thromboplastin apoprotein was partially purified from human brain. The apoprotein was recombined with mixed phospholipids to yield active thromboplastin. The recombined thromboplastin induced proteolytic activation of isolated human factor IX in the presence of factor VII and Ca2+. The clotting times of various deficient plasmas were determined as a(More)
This paper presents insights gained from applying biological vision mechanisms in the context of computer vision algorithm design, implementation and initial evaluation. In this paper a software-based space variant log(z) retina tessellation is used to sample the underlying image, maintaining the high resolution at the central foveal region and an(More)
