The finding that a simple single-celled organism can traverse a maze near optimally provides a challenge to some current ideas in artificial intelligence. In this paper, we present a simple explanation for such behavior and a computational model based on decision trees and ant algorithmics. The behavior of simple biological organisms may provide insights into the nature and evolution of intelli...

Sessile cultures of the skin bacteria Staphylococcus saprophyticus and Corynebacterium xerosis were grown using novel fine-celled foam substrata to test the outcome of challenge by methicillin-resistant Staphylococcus aureus or Pseudomonas aeruginosa under three growth medium regimens (simulated sweat, simulated serum or simulated sweat substituted with simulated serum during the microbial chal...

Metamaterials have emerged as promising solutions for manipulation of sound waves in a variety of applications. Locally resonant acoustic materials (LRAM) decrease sound transmission by 500% over acoustic mass law predictions at peak transmission loss (TL) frequencies with minimal added mass, making them appealing for weight-critical applications such as aerospace structures. In this study, pot...
