Comment: There was angiocentric involvement, with atypical cells that were positive for the B cell marker CD20, with more benign appearing CD3 positive T cells also present. Reticulin stain showed reticulin proliferation about involved vessels. In situ hybridization of lesions showed strong positivity for EBV. Some members of the audience noted the presence of intranuclear inclusions in the les...
متن کاملPortrait
Born in 1944, I grew up in a world in which polio was both a gripping fear and real threat. Then in a matter of a few years-polio was eradicated by a vaccine developed by Jonas Salk. Later I learned that Salk's efforts were built on pioneering work of many others, including John Enders, Thomas Weller and Frederick Robbins (Nobelists, 1954), and David Bodian, who pioneered studies of polio patho...
متن کاملAutomatic Refinement of Split Binary Semaphore
Binary semaphores can be used to implement conditional critical regions by using the split binary semaphore (SBS) technique. Given a specification of a conditional critical regions problem, the SBS technique provides not only the resulting programs but also some invariants which ensure the correctness of the solution. The programs obtained in this way are generally not efficient. However, they ...
متن کاملk-p-Infix codes and semaphore codes
In this paper we introduce the concepts of k-p-in x codes, n-k-ps-in x languages, n-k-in xout x codes, and n-k-pre x-su x languages, which are natural generalizations of our previous work on k-pre x codes, k-in x codes and so on. We obtain several properties of k-p-in x codes and semaphore codes. The relations and hierarchies of k-p-in x codes, n-k-ps-languages, and n-kpre x-su x languages, and...
متن کاملDistributed Semaphore in a Messenger Environment
The messenger paradigm advocates the exchange of programs called messengers between communicating hosts instead of messages. Each host contains a messenger execution environment called messenger platform. Messengers are expressed in a language understood by all the platforms. A distributed messenger environment is a collection of messenger platforms linked through an unreliable network offering...
