Strain Engineering of the Topological Gap and Tunable Chern Numbers in the 2D Kagome Metal-Organic Framework Eu$_2$(C$_6$H$_4$)$_3$

The quantum anomalous Hall effect carries dissipationless chiral edge currents without an external magnetic field, yet raising its operating temperature and controlling the number of edge channels remain difficult. Using first-principles calculations, we identify the two-dimensional metal-organic kagome ferromagnet Eu$...

Multifunctional hydrogel assembled from phenylboronic acid-chitosan and Polygonati Rhizoma polysaccharide for accelerated radiation-combined wound healing.

Combined radiation-wound injury (CRWI) is difficult to heal because of persistent oxidative stress, inflammation, and impaired angiogenesis. Herein, a multifunctional pH and reactive oxygen species (ROS)-responsive hydrogel was prepared by dynamic crosslinking of Polygonati Rhizoma-derived polysaccharide fraction (PC)...

Scoring the Wrong Question: Readout Failures in Constrained-Option Evaluation

Constrained-option scoring reads a model's probabilities for a fixed set of permitted answers, so it returns a score even when the model is about to write something else. We study a prompt that quotes a multiple-choice item, ending in the item's own answer instruction, and asks for a forecast of whether a reader model...
