Ignorance can be evolutionarily beneficial

Information is increasingly being viewed as a resource used by organisms to increase their fitness. Indeed, it has been formally shown that there is a sensible way to assign a reproductive value to information and it is non-negative. However, all of this work assumed that information collection is cost-free. Here, we account for such a cost and provide conditions for when the reproductive value...

Can impurities be beneficial to photovoltaics?

The state of the art of the intermedíate band solar cells is presented with emphasis on the use of impurities or alloys to form bulk intermedíate band materials. Quantum dot intermedíate band solar cells start to present already attractive efficiencies but many difficulties jeopardize the immediate achievement of record efficiency cells. To complement this research it is worthwhile examining bu...

One drop can be beneficial, one swig can be deadly: tetrahydrozoline intoxication.

Tetrahydrozoline is a commonly used imidazoline derivative with serious side effects and toxicity, particularly in small children. A one-year-old boy was admitted to the emergency department (ED) after he accidentally ingested about half a bottle of nasal decongestant solution containing tetrahydrozoline. He was unconscious, hypothermic and bradycardic on presentation. His respiration was irreg...

Can "Bill-and-Keep" Peering Be Mutually Beneficial?

We analyze “Bill-and-Keep” peering between two providers, where no money exchanges hands. We assume that each provider incurs costs from its traffic traversing its as well as the peer’s links, and compute the traffic levels in Nash equilibrium. We show that Nash strategies are not blind, i.e., they are neither pure hot-potato nor pure cold-potato strategies. Rather, the Nash strategies involve ...
