Adaptation to abiotic conditions drives local adaptation in bacteria and viruses coevolving in heterogeneous environments

Adaptation to abiotic conditions drives local adaptation in bacteria and viruses coevolving in heterogeneous environments

Parasite local adaptation, the greater performance of parasites on their local compared with foreign hosts, has important consequences for the maintenance of diversity and epidemiology. While the abiotic environment may significantly affect local adaptation, most studies to date have failed either to incorporate the effects of the abiotic environment, or to separate them from those of the bioti...

Comparative Adaptation of some pox viruses in two cell systems

Thermal adaptation of viruses and bacteria.

A previously established multiscale population genetics model posits that fitness can be inferred from the physical properties of proteins under the physiological assumption that a loss of stability by any protein confers the lethal phenotype to an organism. Here, we develop this model further by positing that replication rate (fitness) of a bacterial or viral strain directly depends on the cop...

Video Adaptation for Heterogeneous Environments

The explosive growth of compressed video streams and repositories which are accessible worldwide and the recent addition of new video-related standards, such as H.264/AVC, MPEG-7, and MPEG-21, have stimulated research for new technologies and applications in the area of multimedia ar-chitectures, processing, and networking. Current communication networks exhibit a wide range of capabilities, in...

Universal Profiling for Content Negotiation and Adaptation in Heterogeneous Environments

This position paper focuses on the content negotiation and adaptation of services in heterogeneous environment and this using the concept of universal profiling. We discuss our vision to achieve an advanced content negotiation. For this, we define a profiling schema that includes the utile description of the entire component that can participate in the final deliverance of services. The defined...
