BACKGROUND Advances in minimally invasive surgical techniques will require new types of instrument end-effectors for smaller, longer, and flexible instruments. These include a new class of multifunctional instruments capable of performing more than 1 task with a single set of working jaws. Furthermore, it is desired that multifunctional instruments be designed to provide improved dexterity comp...

We study dipole-mode and scissors-mode oscillations of a harmonically trapped dipolar supersolid, composed droplets arranged on one-dimensional (1D) or 2D lattice, to establish the robustness its crystalline structure under translation rotation, using beyond-mean-field model including Lee-Huang-Yang interaction. The atoms are polarized in $z$ direction with supersolid lying $x\text{\ensuremath{...

This paper is an expansion of my lecture for David Epstein’s birthday, which traced a logical progression from ideas of Euclid on subdividing polygons to some recent research on invariants of hyperbolic 3– manifolds. This “logical progression” makes a good story but distorts history a bit: the ultimate aims of the characters in the story were often far from 3–manifold theory. We start in sectio...

In two eye-tracking experiments the role of contrastive pitch accents during the on-line determination of referents was examined. In both experiments, German listeners looked earlier at the picture of a referent belonging to a contrast pair (red scissors, given purple scissors) when instructions to click on it carried a contrastive accent on the color adjective (L + H*) than when the adjective ...

In the children's game of rock-scissors-paper, players each choose one of three strategies. A rock beats a pair of scissors, scissors beat a sheet of paper and paper beats a rock, so the strategies form a competitive cycle. Although cycles in competitive ability appear to be reasonably rare among terrestrial plants, they are common among marine sessile organisms and have been reported in other ...
