Profile of Daniel H. Janzen.

When Daniel Janzen gave his acceptance speech for the 1997 Kyoto Prize, he disappointed many people who had come to hear a preeminent biologist discuss iconic studies, from ant–acacia mutualism to seed predation (1, 2). “They expected a talk about science, but I’d switched to conservation,” explains Janzen, DiMaura Professor of Conservation Biology at the University of Pennsylvania. Janzen, who...

Setting Limits: Medical Goals in an Aging Society, by Daniel Callahan.

A novel approach to temporal pattern recognition was recently introduced in the literature, called liquid computing. The model used was very complex, thus the present study uses a simplified version that is easier to understand. By exploring properties of the system with the simple setup, a better unders tanding of the complex version can be reached. A liquid computer needs a liquid memory and ...

In the context of the AdS/CFT correspondence it is well-known that correlation functions of local operators in the CFT are dual to boundary correlators computed in anti-de Sitter space. But from the point of view of AdS supergravity one of the most interesting questions is how quasi-local bulk gravitational physics emerges from the CFT. The most direct way to address this question is to study c...
