Synthesis of Bulk Superconducting LiNbO2 Crystals Through CaH2 Reduction

Advanced Materials, EarlyView.
CaH2 reduction reconstructively transforms insulating LiNbO3 single crystals into superconducting bulk LiNbO2 with a critical temperature of Tc = 14.4 K. Scanning electron microscopy reveals large‐volume, high‐yield phase conversion. Magnetization measurements demonstrate a robust ∼ 77% Meissner shielding fraction, establishing bulk superconductivity ...

On a combinatorial game with an application to Go-moku

Discrete Mathematics, 1980
AbstractLet A be a finite set and F be a family of its subsets. Two players pick m resp. n points alternately from A. I wins if he picks all the points of some element of F, otherwise II wins. We give a sufficient condition for II to have a winning strategy. Using this we prove the following statement. If in Go-moku I occupies m places, and II occupies

Turning Nd‐Fe‐B Swarf Into High‐Value Bulk Feedstocks via Sustainable Hydrogen Plasma: From Rare‐Earth Oxides to Metals and Hydrides

Advanced Materials, EarlyView.
Oxidized Nd‐Fe‐B magnet swarf is transformed into valuable bulk feedstock through a single‐step hydrogen plasma process. The reaction converts complex rare‐earth‐containing waste into separated metallic, oxide, and hydride fractions without acid leaching.

The Sequential Join of Combinatorial Games

, 2007
We study the sequential join of combinatorial games, and show that all combinatorial games form a monoid under this operation. We also show how this can be used to study games such as Childish Hackenbush and a new variant of normal play Hackenbush.

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

Advanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

Defined Matrices Reveal Epithelial‐ and Mesenchymal‐Specific Responses to Stiffness and Adhesion in Human iPSC‐Derived Intestinal Organoids

Advanced Materials, EarlyView.
Defined PEG hydrogels enable human iPSC‐derived intestinal organoid culture without Matrigel. PEG‐ and Matrigel‐cultured organoids both support duodenal‐like epithelial identity, but direct comparison reveals subtle epithelial differentiation‐marker shifts and stronger mesenchymal ECM‐remodeling/integrin programs in PEG.

Cost-Aware Coalition Formation in Multi-Defender Network Security Games: Mathematical Modeling and Optimization

Mathematics
Distributed network security requires multiple defenders to make coupled resource allocation and coordination decisions under limited budgets, connectivity-dependent risks, and non-negligible coordination costs.
