Advanced Healthcare Materials, EarlyView.A thermo‐responsive poly(2‐oxazoline)‐based injectable formulation is developed to modulate intraocular pressure (IOP) in both normal and hypotonic eyes. By adjusting the PEG content, the aggregation behavior is finely tuned, enabling IOP elevation without long‐term deposition.

Abnormal expected utility and event study abnormal returns
Economics Letters, 1994 Abstract Event study is employed by measuring the abnormal return around the event date. If risk changes this methodology is questionable. We suggest the concept of abnormal expect utility which relies on the whole distribution and not just the mean return.

3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters
Advanced Robotics Research, EarlyView.This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...
