Rapid and Reversible Morphing to Enable Multifunctionality in Robots
This article introduces a rapid, reversible, and repeatable morphing robot through a bistable latch‐mediated, spring actuated (LaMSA) mechanism. This enables an untethered, multifunctional robot to near‐instantaneously (< 50 ms) and reversibly switch between a flying and driving configuration to navigate through different environments.

Multistable Composite Laminate Grids as a Design Tool for Soft Reconfigurable Multirotors
Flexible, lightweight, stable: the reconfigurable multirotor combines stable flight in multiple shapes with low‐energy reconfiguration. Utilizing optimized multistable composites, it achieves self‐locking in open and folded configurations, cutting width‐span by 48% and allowing for safe gap traversal.

Complexity and operator growth for quantum systems in dynamic equilibrium
Krylov complexity is a measure of operator growth in quantum systems, based on the number of orthogonal basis vectors needed to approximate the time evolution of an operator.

Relational Lorentzian Asymptotically Safe Quantum Gravity: Showcase Model
In a recent contribution, we identified possible points of contact between the asymptotically safe and canonical approaches to quantum gravity. The idea is to start from the reduced phase space (often called relational) formulation of canonical quantum ...

This article answers the question “Where is the best place to apply compliance in a multirotor micro aerial vehicle to make it more collision‐resilient?” by analyzing the output data of more than 1200 drone collision tests for four main configurations of micro‐quadcopters each possessing a unique softness layout of physical frame.

Collision-space-time: Unified quantum gravity
We have recently presented a unified quantum gravity theory [1]. Here we extend on that work and present an even simpler version of that theory. For about hundred years, modern physics has not been able to build a bridge between quantum mechanics and ...
