Common Risk Factors in Currency Markets [PDF]
We identify a 'slope' factor in exchange rates. High interest rate currencies load more on this slope factor than low interest rate currencies. As a result, this factor can account for most of the cross-sectional variation in average excess returns ...

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract
Advanced Robotics Research, EarlyView.We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a
