Fewer orphans than previously thought?
The editors of IJE have commented on the surprising number of papers in their journal and other journals that fail to be cited even once. According to their most recent calculations, 17% of papers in IJE and 40% of those in Epidemiology achieve no recognition in the scientific literature. These numbers do not seem very plausible, so I decided to check. Using the most recent data available from ...

متن کاملMycobacterium microti: more widespread than previously thought.
Mycobacterium microti typically causes disease in voles, wood mice, and shrews (6). Only rarely has this bacterium been isolated from other animals, among which are a llama, cats, pigs, a rock hyrax, and a ferret (2, 4, 5). Recently, M. microti isolates from different sources were characterized by using novel genetic markers (5), and this study for the first time disclosed four cases of M. micr...
متن کاملMycobacterium microti: More diverse than previously thought.
Mycobacterium microti is a member of the Mycobacterium tuberculosis complex of bacteria. This species was originally identified as a pathogen of small rodents and shrews and was associated with limited diversity and a much reduced spoligotype pattern. More recently, specific deletions of chromosomal DNA have been shown to define this group of organisms, which can be identified by the absence of...
متن کاملThere Are Asymptotically Far Fewer Polytopes than We Thought
The problem of enumerating convex polytopes with n vertices in R has been the object of considerable study going back to ancient times (see [4, §13.6] for some remarks about the history of this problem since the nineteenth century). While significant progress has been made when the number of vertices was not too much larger than the dimension [4], little had been known above dimension 3 in the ...
