Space and Time in Loop Quantum Gravity [PDF]
arXiv, 2018 Quantum gravity is expected to require modifications of the notions of space and time. I discuss and clarify how this happens in Loop Quantum Gravity.

Rapid and Reversible Morphing to Enable Multifunctionality in Robots
Advanced Intelligent Systems, EarlyView.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.

Dynamics of Fricke–Painlevé VI Surfaces
DynamicsThe symmetries of a Riemann surface Σ∖{ai} with n punctures ai are encoded in its fundamental group π1(Σ). Further structure may be described through representations (homomorphisms) of π1 over a Lie group G as globalized by the character variety C=Hom(π1,

Fundamentals of quantum gravity [PDF]
Journal of Physics: Conference Series, 2007 The outline of a recent approach to quantum gravity is presented. Novel ingredients include: (1) Affine kinematical variables; (2) Affine coherent states; (3) Projection operator approach toward quantum constraints; (4) Continuous-time regularized functional integral representation without/with constraints; and (5) Hard core picture of ...

Multistable Composite Laminate Grids as a Design Tool for Soft Reconfigurable Multirotors
Advanced Intelligent Systems, EarlyView.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.

, 2019 The creation of matter by the structure of the basic quantum fields causes an unbalance within the scalars of the flat Higgs field. The result is Newtonian gravity, scalar vectors that act like a push force.
