Advanced Science, EarlyView.A bioorthogonal rhodamine/PEG crosslinking strategy is introduced to engineer dense collagen hydrogels with high mechanical resilience and cytocompatibility. Integration with wet‐spinning enables the fabrication of uniaxially aligned, cell‐laden collagen filaments that activate mechanotransductive signaling and support functional muscle regeneration in

Wave‐Partition‐Governed Dual‐Site Spallation in Single Crystals
Advanced Science, EarlyView.Crystalline anisotropy shapes shock‐wave propagation and the resulting damage evolution in single crystals. Large‐scale molecular dynamics and damage modeling uncover a dual‐spallation mechanism driven by anisotropic elasticplastic wave separation, which mitigates damage accumulation.

Factorization of hermitian matrix polynomials with constant signature
Linear Algebra and its Applications, 1993 A new proof is given for the following result proved in the paper by \textit{I. Gohberg}, \textit{P. Lancaster} and \textit{L. Rodman} [Linear Multilinear Algebra 11, 209-224 (1982; Zbl 0486.15008)]. If a polynomial \(A(t)\) with complex Hermitian matrices as coefficients has nonzero determinant and is such that \(A(t)\) has constant signature for all ...
