The rate of serotypic change is estimated to be 10-3-10 -4 per cell per generation (2). The antigenic repertoire of B. hermsii (2) may be as extensive as that of another vector-transmitted and blood-borne pathogen, Trypanosoma brucei, a eucaryote (3, 4)...

متن کاملAutomated Assessment and Improvement of OpenStreetMap Data
The challenging task of creating an accurate and up-to-date map of the fast changing world can be easily solved by means of crowdsourcing. OpenStreetMap (OSM) is a good example of this approach. However, the quantification of quality and suitability of OSM for certain applications is necessary as this database is primarily constructed by amateurs. Researchers have proposed several parameters to...
