Improving Numerical Accuracy for the Viscous-plastic Formulation of Sea Ice By Tongtong Li, Anne E. Gelb, and Yoonsang Lee Sea ice dynamics play a critical role in shaping the ice cover in polar regions. The accurate modeling and simulation of such dynamics are crucial for the prediction of environmental variables, which in turn find a wide range of practical applications ....

Two Approaches for Representing the Stochastic Dynamics of Foraging Behaviors By Jillian Kunze “Foraging is a ubiquitous behavior that all animals do, as they self-sustain by searching for food to acquire energy,” Ahmed El Hady of the Max Planck Institute of Animal Behavior and the Center for Advanced Study of Animal Behavior (formerly of Princeton University) said. Forag...

Origami and the Structure of Materials By Huan Liu, Paul Plucinsky, Fan Feng, Arun Soor, and Richard D. James The world’s population is growing approximately linearly by about 80 million individuals per year, leaving less and less space per person on average. Perhaps this growth is responsible for an explosion of interest in origami—...

Casting Out Sevens -- from Wolfram MathWorld A method for verifying the correctness of an arithmetical operation on natural numbers, based on the same principle as casting out nines. The methods of sevens takes advantage of the fact that the residue (mod 7) of a sum (or product) must be equal to the sum (or product) of the residues of the summ...
