Ultrathin Hydrogel Membranes Inspired by Soap Films Enable Physiologically Relevant Breathing Lung Models

Advanced Materials, EarlyView.
A soap‐film inspired strategy enables the fabrication of ultrathin yet robust GelMA‐PAAm membranes for breathing lung culture. The hydrogel membrane supports long‐term cyclic deformation under air‐liquid interface conditions, enabling physiologically relevant breathing motions of engineered lung tissue culture. ABSTRACT Breathing continuously stretches

Multi-relation-pattern knowledge graph embeddings for link prediction in hyperbolic space

International Journal of Intelligent Networks
The aim of Knowledge Graph Embedding (KGE) is to acquire low-dimensional representations of entities and relationships for the purpose of predicting new valid triples, thereby enhancing the functionality of intelligent networks that rely on accurate data

Neutron Reflectometry and Compression of Graded Hydrogel Surfaces

Advanced Materials Interfaces, EarlyView.
Highly‐entangled and covalently‐crosslinked hydrogels with thin and thick surface gel layers are compressed in neutron reflectometry experiments. Surface gel layer thickness dictates the extent to which the polymer network at the surface of a hydrogel collapses, while crosslinking chemistry, and therefore elastic modulus, impacts the pressure at which ...

In Situ Change in Contact Angle of a Sessile Droplet on a Magnetoactive Elastomer

Advanced Materials Interfaces, EarlyView.
Contact angles of persistent μL$\mu{\rm L}$‐sized water droplets on a mechanically soft MAE surface under time varying magnetic fields differ from those of newly deposited droplets. The ability to quickly alter the material properties allows one to observe intriguing droplet‐material interactions.

Infinite energy harmonic maps from quasi-compact Kähler surfaces

Advanced Nonlinear Studies
We construct infinite energy harmonic maps from a quasi-compact Kähler surface with a Poincaré-type metric into an NPC space. This is the first step in the construction of pluriharmonic maps from quasiprojective varieties into symmetric spaces of non ...

Asymptotically hyperbolic extensions and estimates for an analogue of the Bartnik mass [PDF]

, 2019
Given a metric $g$ on the $2$-sphere $S^2$ with Gaussian curvature bound below by $-3$, and non-negative constant $H$, we construct asymptotically hyperbolic manifolds whose boundary is isometric to $(S^2, g)$ and has mean curvature $H$ (with respect to ...
