Exit Gordianus, but how? Shapur’s trilingual inscription revisited

How do tears exit?

The mechanisms of tear flow, blinking, and tear drainage were studied employing high speed slit-lamp cinematography using a polystyrene microsphere suspension as a tracer of tear movement. It was demonstrated that: (1) Tears are drawn into the canaliculi during the relaxation phase of blinking. (2) Both superior and inferior puncta function as normal tear drainage routes. (3) The superior punct...

When and How To Exit Quantitative Easing?

According to former Fed Chairman Ben Bernanke (2009, p. 5), the essence of LSAP is “credit easing” (CE)—that is, reducing the cost of private borrowing by direct purchases of privately issued debt instead...

Sensing Polygon Poses by Inscription

Yan-Bin Jia Michael Erdmann The Robotics Institute School of Computer Science Carnegie Mellon University Pittsburgh, PA 15213-3891 Abstract Industrial assembly involves sensing the pose (orientation and position) of a part. E cient and reliable sensing strategies can be developed for an assembly task if the shape of the part is known in advance. In this paper we investigate the problem of deter...

Small at Birth, but How Small? The Definition of SGA Revisited.

50 years of published discussion of the definition of SGA [3–5] . The 10th percentile was chosen as a cutoff for SGA in the 1960s as a result of multiple studies indicating that infants born at or below the 10th percentile have increased mortality compared to gestational age-matched controls [4] . It is worth noting that these studies were performed on neonates born at high altitudes, who tend ...
