Today, there is a wide variety of devices ranging from PC’s, game consoles, up to smartphones and tablets. These computing devices have major differences in performance and make mesh decimation still active in the field of research. One of the latest topics in the area has been to create simplification algorithms considering visual similarity. However, the full potential of most visual simplifi...

Kamien Department of Physics and Astronomy, University of Pennsylvania, Philadelphia, PA 19104 16 August 2000 Abstract We show that Scherk’s first surface, a one-parameter family of solutions to the minimal surface equation, may be written as a linear superposition of itself.

D isease emergence and biodiversity loss are among the most pervasive environmental problems confronting science and society. Widespread and dramatic losses of amphibian populations and species represent the deadly intersection between these issues (1), as illustrated by the work of Lips et al. (2) in this issue of PNAS. Amphibians are one of the most imperiled groups of vertebrates, with nearl...
