Europhysics Letters (EPL), 1992 Erratum for Europhys. Lett., 17 (1), pp. 1-4 (1992) On the bottom of page 2, one should replace ρ = p by ρ = − p. As a result the vacuum energy density ρ around matter is increased (not lowered as was mentioned on page 3). The corrected equations were applied in [1].

Harnessing Discrete Differential Geometry: A Virtual Playground for the Bilayer Soft Robots
Advanced Intelligent Systems, EarlyView.A discrete differential geometry‐based framework is developed to model the mechanics of bilayer structures with asymmetric geometry and material properties. The simulations capture dynamic bending and contact interactions in soft robotic grasping, crawling, jumping, and swimming, demonstrating the framework's versatility for programmable shape morphing

Journal of High Energy PhysicsAbstract We present the manifestly covariant canonical operator formalism of a Weyl invariant (or equivalently, a locally scale invariant) gravity whose classical action consists of the well-known conformal gravity and Weyl invariant scalar-tensor gravity, on the basis of the Becchi-Rouet-Stora-Tyupin (BRST) formalism.

Electronic‐Free Particle Robots Communicate through Architected Tentacles
Advanced Intelligent Systems, EarlyView.This work introduces a new class of particle robots that communicate without any electronic components. Their communication protocols are encoded in the geometry of their tentacles are and realized solely through physical contact. Building on these simple communication schemes, electronic‐free particle robots can achieve a range of collective ...

Symmetry Breaking Metamaterial Sleeve Actuators
Advanced Intelligent Systems, EarlyView.Metamaterial sleeves are designed to impart to a soft inflatable structure, nonlinear characteristics within the pressure–volume domain. By tuning the unit cells of the metamaterial sleeve, symmetry breaking is achieved during the inflation–deflation cycle.
