Parallel Selection: Evolution's Surprising Predictability

Predictability and Parallelism of Multitrait Adaptation.

Environments shape the traits of organisms. Environmental variation may rarely alter selection on only a few traits, but instead precipitate wholesale changes of the multidimensional selective regime-many traits might experience divergent selection across divergent environments. Such changes in selection can elicit multifarious evolution. How predictable (from theory) and how parallel (consiste...

On the origin of cancer.

In this paper, I present a highly unorthodox and provocative hypothesis, namely that cancer is an evolutionarily derived phenomenon, dormant in every human cell and actively triggered in certain individuals. Cancer is shown to help maintain the integrity of the common gene pool through active elimination of individuals, thus serving a definite advantage for the survival of the species. Those in...

Evolution's “Molecular Clock”: Not So Dependable After All?

Value Speculation Mechanisms for EPIC Architectures

Value speculation has the potential of extending instruction level parallelism by breaking the barrier caused by chains of pure dependencies. To date, the literature has focused primarily on implicitly parallel architectures with superscalar cores. This paper presents a scheme for integrating value speculation into an explictly parallel instruction computer ISA, such as IA-64 or HPL-PD. It pres...

Redundancy Allocation Combined with Supplier Selection for Design of Series-parallel Systems

In this paper a redundancy allocation problem is studied where for the first time the supplier selection is taken into consideration and redundant components are provided from appropriate suppliers with the most suitable offers such as discount on buying price of components, warranty length for components, things like that, so that the system reliability, profit and the warranty length proposed...
