Gauging the diamond: integrable coset models from twistor space
Recent work has shown that certain integrable and conformal field theories in two dimensions can be given a higher-dimensional origin from holomorphic Chern-Simons in six dimensions. Along with anti-self-dual Yang-Mills and four-dimensional Chern-Simons,

Time-like surfaces with zero mean curvature vector in 4-dimensional neutral space forms
Let M be a Lorentz surface and F:M→N a time-like and conformal immersion of M into a 4-dimensional neutral space form N with zero mean curvature vector.

Summary: In previous work a hyperbolic twistor space over a paraquaternionic Kähler manifold was defined, the fibre being the hyperboloid model of the hyperbolic plane with constant curvature \(-1\). Two almost complex structures were defined on this twistor space and their properties studied.

A Computational Journey Toward an Optimal Design for Metamaterial Epicardial Passive Sleeves
Passive epicardial sleeves are evaluated in 3D in‐silico heart models to reveal how sleeve geometry, stiffness, anisotropy, and metamaterial architecture influence cardiac mechanics after myocardial infarction. A continuum‐to‐auxetic design exploration shows that region‐specific mechanical engagement can reduce infarct bulging and modulate torsional ...

At the Pointy End of Mechanobiology: AFM for Transient Biomechanical Analysis
Stem cell mechanosensitivity governs lineage commitment through mechanotransduction, but capturing these transient changes in living cells remains challenging. Advanced atomic force microscopy enables high‐resolution analysis of mechanical properties, real‐time protein distribution, and gene expression, offering fresh insights into cell‐environment ...
