Supersymmetric twists in twistor space and holography
Journal of High Energy PhysicsWe compute some supersymmetric twists of field theories in twistor space, including the minimal supersymmetric and the chiral algebra twists of supersymmetric self-dual Yang-Mills, and the minimal twist of N $$ \mathcal{N} $$ = 1 self-dual supergravity ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?
Advanced Materials, EarlyView.This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Hessian of the natural Hermitian form on twistor spaces
, 2016 International audienceWe compute the hessian of the natural Hermitian form successively on the Calabi family of a hyperkähler manifold, on the twistor space of a 4-dimensional anti-self-dual Riemannian manifold and on the twistor space of a quaternionic ...

On the moduli space of superminimal surfaces in spheres
International Journal of Mathematics and Mathematical Sciences, 2003 Using a birational correspondence between the twistor space of S2n and projective space, we describe, up to birational equivalence, the moduli space of superminimal surfaces in S2n of degree d as curves of degree d in projective space satisfying a ...

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion
Advanced Materials, EarlyView.We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

Seamless Mechanical Programming Through Hybrid Epoxy–Acrylate Printing for Soft–Rigid Robots
Advanced Materials, EarlyView.Hybrid epoxy‐acrylate printing enables seamless fabrication of soft–rigid robotic systems with covalently integrated interfaces and functionally graded mechanics. Grayscale exposure expands the accessible material space, enabling spatially programmed actuation through patterned stiffness while revealing the mechanics and durability of continuously ...

N $$ \mathcal{N} $$ = 2 supersymmetry in the twistor description of higher-spin holography
Journal of High Energy PhysicsWe study the holographic duality between higher-spin (HS) gravity in 4d and free vector models in 3d, with special attention to the role of N $$ \mathcal{N} $$ = 2 supersymmetry (SUSY).
