Rodent-repellent Studies. I. Method for the Evaluation of Chemical Repellents
Journal of the American Pharmaceutical Association (Scientific ed.), 1949A biological assay procedure and a method for the numerical expression of results have been devised for the determination of the repellency to rodents of different chemical compounds. The procedure is based upon the degree of acceptability of foods containing the candidate repellents, and has been shown to offer a rapid, reliable measure of repellent ...

Current Opinion in Insect Science
Repellents are used by humans and by animals to protect themselves from bites, and they contribute controlling the transmission of vector-borne diseases. There are numerous chemical formulations of both natural and synthetic origins, as well as electronic devices, that are commercially available worldwide alleged to provide personal protection against ...

Nature Microbiology, 2018
Streptococcus pneumoniae strains colonizing the nasopharynx use quorum sensing and fratricide to outcompete incoming strains, thereby retaining ownership of the host. This occurs via activation of the competence regulon, induction of lytic proteins, and turning the invader into a source of DNA for genetic exchange.

Physical Review E, 2007
We show the existence of strange nonchaotic repellers--that is, systems with transient dynamics whose nonattracting invariant set is fractal, but whose maximum Lyapunov coefficient is zero. We introduce the concept using a simple one-dimensional map and argue that strange nonchaotic repellers are a general phenomenon, occurring in bifurcation points of

Routing Physarum with repellents
The European Physical Journal E, 2010Plasmodium of Physarum polycephalum is a single cell with many nuclei. Plasmodium is an easy-to-experiment-with biological substrate, a multi-functional bio-material used to implement novel and future computing architectures. The plasmodium exhibits typical features of excitable chemical systems and capable for distributed sensing, parallel information
