Sizing the Government [PDF]

open access: yes
Is there such a thing as an optimal government size? We investigate by the non-parametric Data Envelopment Analysis (DEA) the so-called `Armey curve' which claims an inverted U-shaped relationship between government size and economic performance. The DEA

Melt Electrowriting High Resolution Poly(ethylene‐co‐vinyl acetate) Scaffolds for Soft Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Supramolecular Engineering of Fluid Pressure in Filamentous Hybrid Double Network Hydrogels for 3D Chondrocyte Culture

open access: yesAdvanced Healthcare Materials, EarlyView.
Inspired by the water‐rich and interconnected biopolymer networks of native load‐bearing tissues, we disclose a connectable design for a hybrid filamentous supramolecular and covalent double network hydrogel generated through in situ photopolymerization.

A Tri‐Culture Heart‐on‐a‐Chip Platform With iPSC‐Derived Cardiac Cells for Predictive Cardiotoxicity Testing

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...
