We studied the staining pattern of HMB-45 antibody in 29 compound Spitz nevi (SNs) of the epithelioid cell variety, 17 of which showed extension of nevus cells into the reticular dermis (i.e., "deep"); 20 ordinary compound nevi (CNs), all with a deep dermal component; and 22 primary cutaneous invasive malignant melanomas (MMs) (excluding the desmoplastic(More)
Because Howard H. Aiken expressed such an admiration for the ideas of Charles Babbage, the machine he conceived - brought into being through the engineering talents of IBM (the Mark I or ASCC) - is often cited as an example of Babbage's dream come true. This article explores the depth and extent of Aiken's knowledge of Babbage's ideas, the stage of his own(More)
