Deployable 3D‐Printed Vascular Stent with Surface‐Catalysed Endogenous Nitric Oxide Generation

open access: yesAdvanced Materials, EarlyView.
A deployable 3D‐printed vascular stent was fabricated with surface‐catalyzed endogenous nitric oxide generation, representing a promising new direction for stent development. The stent can be remotely controlled by magnetic force in its compressed state and fully deployed at the target site using an untethered heat source, potentially eliminating the ...

Pattern Formation in Non‐Equilibrium Architected Materials

open access: yesAdvanced Materials Technologies, EarlyView.
This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Teaching to the test: A very large red herring

open access: yesNonpartisan Education Review, 2016
Elevating teaching-to-the-test to dogma, from the beginning with the distortion of Dr. Cannell’s findings, has served to divert attention from scandals that should have threatened US educators’ almost complete control of their own evaluation.[10] Had the

Accurate Liability Estimation Improves Power in Ascertained Case Control Studies

open access: yes, 2015
Linear mixed models (LMMs) have emerged as the method of choice for confounded genome-wide association studies. However, the performance of LMMs in non-randomly ascertained case-control studies deteriorates with increasing sample size.

First Observational Tests of Eternal Inflation: Analysis Methods and WMAP 7-Year Results [PDF]

open access: yes, 2011
In the picture of eternal inflation, our observable universe resides inside a single bubble nucleated from an inflating false vacuum. Many of the theories giving rise to eternal inflation predict that we have causal access to collisions with other bubble

Ultra‐Thin Soft Pneumatic Actuation for Minimally Invasive Neural Interfacing

open access: yesAdvanced Materials Technologies, EarlyView.
Parylene C is a common polymer in bioelectronics, favored for its biological and chemical inertness. However, this makes bonding layers of Parylene C together very challenging. Here it is a laser to selectively weld layers of Parylene C to create high‐pressure fluidic actuation devices.

Exchange-rate Pass Through, Openness, and the Sacrifice Ratio [PDF]

open access: yes, 2013
Considerable recent work has reached mixed conclusions about whether and how globalization affects the inflation–output trade-off and suggests that the ultimate effect of openness on the output–inflation relationship is influenced by a variety of factors.
