Sensory trade-offs predict signal divergence in Surfperch.
Unidirectional elaboration of male trait evolution (e.g., larger, brighter males) has been predicted by receiver bias models of sexual selection and empirically tested in a number of different taxa. This study identifies a bidirectional pattern of male trait evolution and suggests that a sensory constraint is driving this divergence. In this system, the inherent trade-off in dichromatic visual ...
متن کاملCapacity versus availability trade-offs for availability-based routing
The core idea of availability-based routing consists of exploiting the availability as a link-state metric: this kind of approach has received attention by virtue of the ability to avoid excessively unavailable paths. A recent availabilitybased heuristic design technique for reliable optical transport networks [IEEE Sel. Areas Commun. 23, 1520 (2005)] showed that the availability metric returns...

P roteomics is defined as the protein complement of the genome and involves the complete analysis of all the proteins in a given sample [1,2]. Several technologies are involved, and numerous questions concerning the proteins are addressed. What proteins are contained in a biological sample? At what concentration do the proteins exist? How do protein expression levels alter in different samples?...

When should a new instrumental technique or analytical method be adopted for use in clinical chemical analyses? Many clinical methods are approved by the FDA based on the 510 k process, which requires demonstration that a new test is at least as good as those already in the marketplace. This is justified from both a scientific and free-market regulatory perspective when replacement of a sound m...
