Pre‐Torsion Tubular Metamaterials: Multi‐Effect Integration for Advanced Functional Applications
Advanced Science, EarlyView.Through a pre‐torsion design paradigm, the authors design and fabricate a class of multi‐effect mechanical metamaterial that synergistically integrates compression‐torsion and auxetic behaviors over an extensive strain range, and their formation mechanisms are quantitatively analyzed and elucidated via experiments and finite element methods.

Piezoelectric‐Metal Phononic Crystal Enabling GHz Tunable Ultrahigh Q Quasi‐BIC Mode
Advanced Science, EarlyView.This study introduces a piezoelectric–metal phononic crystal design based on suspended LiNbO3 thin film that realizes quasi‐BIC resonance. The device achieves GHz operation with an ultrahigh quality factor (≈6.5 × 104) and efficient electrical tunability at low voltage.

Deformations of nodal surfaces
, 2016 In this thesis, we studied the Hodge theory and deformation theory of nodal surfaces. We showed that nodal surfaces in the projective 3-space satisfy the infinitesimal Torelli property. We considered families of examples of even nodal surfaces, that is, those endowed with a double cover branched on the nodes.

Intrinsic Strain‐Driven Topological Evolution in SrRuO3 via Flexural Strain Engineering
Advanced Electronic Materials, EarlyView.A flexural strain platform is developed to isolate intrinsic strain effects on the topological electronic structure in SrRuO3, and demonstrates that the topological properties and associated anomalous Hall effect can be effectively modulated via strain engineering without introducing phase transitions or crystal defects, offering a new approach for ...

Nodal deformations of singularities
Revista Matemática Complutense, 2002 Deformations of a plane curve singularity \((X,0)\) to \(\delta(X,0)\) nodes are studied using the methods of A'Campo. In particular, it is proved that singularities of type \(y^{d-1} - x^d\), \(y^{2d-1} - x^{2d+1}\) can be deformed into real morsifications preserving the degree of the original polynomial.

Annals of Gastroenterological Surgery, EarlyView.Our aim was to compare the outcomes of preoperative chemotherapy with postoperative chemotherapy in patients with resectable colorectal liver metastases treated with CAPOX‐Bev. We demonstrated that both preoperative and postoperative CAPOX‐Bev were safely administered, and preoperative chemotherapy showed a numerically higher treatment compliance rate ...
