Risk of Orthostatic Intolerance During Re-Exposure to Gravity
, 2015 Post-spaceflight orthostatic intolerance remains a significant concern to NASA. In Space Shuttle missions, astronauts wore anti-gravity suits and liquid cooling garments to protect against orthostatic intolerance during re-entry and landing, but in ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion
Advanced Robotics Research, EarlyView.This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Suits Information–Gravity Model (Simon 2.0): Reproducing NGC 3198 and Other Galaxies
We present a revised formulation of the information–gravity model in which the original cosmicradial coupling function 𝜆(𝑟)is replaced by a scale-saturating, galaxy-level effective coupling. Theoriginal information-energy density 𝜌𝐼(𝑟)is preserved exactly, but the new coupling form allowsinformation-induced gravitational effects to become dynamically ...

Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter
Advanced Robotics Research, EarlyView.A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.

This paper outlines the concrete observational and experimental tests capable of falsifying Coherence–Field Gravity (CFG). Because CFG introduces a universal A/rA/rA/r acceleration term sourced by baryonic decoherence, the framework produces sharp, model-independent predictions across Solar System scales, wide binaries, galactic dynamics, cluster ...
