We have determined the amino acid sequence of the variable (V) region of the 8 heavy (H) chain of human IgD isolated from the plasma ofmyeloma patient WAH. This V region is unusual in its amino end group (arginine) and in its length (129 residues). The length is due to 10 insertions in the third complementarity-determining region (CDR3). A computer search showed that no reported CDR3-joining re...

The ability of an eyewitness to recall a briefly-viewed license plate is an under-studied issue with great practical significance. Using large samples of adult participants (total N = 1859), we assessed the memory implications of a current proposal (EZ-ID, n.d.) to include a nameable symbol, such as a triangle or heart, on standard-issue license plates. In two experiments, no overall memory ben...
