The unusual gene architecture of polyubiquitin is created by dual-specific splice sites

open access: yesGenome Biology
Background The removal of introns occurs through the splicing of a 5′ splice site (5′ss) with a 3′ splice site (3′ss). These two elements are recognized by distinct components of the spliceosome. However, introns in higher eukaryotes contain many matches

Improved synchronization performance in DSSS systems

open access: yes, 2002
This paper deals with the synchronization properties of a family of spreading codes, called concatenated codes. New synchronization algorithms are introduced, and the performance of these algorithms is discussed both analytically and by simulation. It turns out that with a minimum of extra hardware, the mean phase acquisition time can be considerably ...
