Prokaryotic evolution was preceded by the chemical evolution leading to polynucleotide self-replication, although no fossils are recognized from that period. Auto-catalysis must have been required at that stage. But autoc

The second proposes that aging in the organism is regulated by factors extrinsic to most cells, such as hormones. The prese

In this paper, we try to shed light on the question how to compare those very different techniques. In particular, we s

As an example we present a simple power control problem for a macrocell-femtocell network scenario. We formulate a dist

many assembly steps can occur in only one particular order, and only one capsid structure generally forms despite the possibility of alternative structures with roughly equal thermodynamic stability. Both features can be explained by rate controls on assembly steps. In T4, different kinds of protein
