Figure 1: Detection of recursive splice sites within long genes expressed in the human brain. Figure 3: The reconstituted 5′ splice site is required for RS-exon skipping. Figure 4: Splice site ...

In this article, we study some new characterizations of primitive recursive functions based on restricted forms of primitive recursion, improving the pioneering work of R. M. Robinson and M. D.

Some strange mathematical sequences are always whole numbers — until they’re not. The puzzling patterns have revealed ties to graph theory and prime numbers, awing mathematicians. Simple, yes, but ...
