We study phase separation in a deeply quenched colloid-polymer mixture in microgravity on the International Space Station using small-angle light scattering and direct imaging. We observe a clear cros...
One property of the emulator framework presented by Grush is that imagery operates off-line. Contrary to this viewpoint, we present evidence showing that mental rotation of a simple figure modulates l...

Many recent proposals to increase the resilience of the Web PKI against misbehaving CAs face significant obstacles to deployment.
These hurdles include (1) the requirement of drastic changes to the e...
A chaotic mapping provides a technique for generating musical variations of an original work. Thistechnique, based on the sensitivity of chaotic trajectories to initial conditions, produces changes in...
Numerous studies have reported long-tailed distributions for various network metrics, including file sizes, transfer times, and burst lengths. We review techniques for identifying long-tailed distribu...
