Consistency problems of hypergravity
Physics Letters B, 1979 Abstract The constraints arising upon coupling a massless spin 5 2 field to gravity are analyzed. In contrast to supergravity, they depend not only on the Einstein tensor, but also on the off-shell (Weyl) components of the curvature. The latter contributions do vanish, however, for “self-dual” systems, i.e., half-flat gravitational and pure ...

Higher Spin Black Holes with Soft Hair [PDF]
, 2016 We construct a new set of boundary conditions for higher spin gravity, inspired by a recent "soft Heisenberg hair"-proposal for General Relativity on three-dimensional Anti-de Sitter. The asymptotic symmetry algebra consists of a set of affine $\hat u(1)$

Hypergravity induced disruption of cerebellar motor coordination [PDF]
Scientific Reports, 2020 AbstractThe cerebellum coordinates voluntary movements for balanced motor activity in a normal gravity condition. It remains unknown how hypergravity is associated with cerebellum-dependent motor behaviors and Purkinje cell’s activities. In order to investigate the relationship between gravity and cerebellar physiology, we measured AMPA-mediated fast ...

PLoS ONE, 2023 In the age of space exploration, the effect of hypergravity on human physiology is a relatively neglected topic. However, astronauts have several experiences of hypergravity during their missions. The main disturbance of altered gravity can be imputed to

Cells, 2023 The earliest effect of spaceflight is an alteration in vestibular function due to microgravity. Hypergravity exposure induced by centrifugation is also able to provoke motion sickness.

Space biomedicine‐oriented bioink and biomimetic blood‒brain barrier
VIEW, EarlyView.Bioinks and bioprinting play a pivotal role in the successful delivery of cell models and the fabrication of tissue models for space biomedicine research. This study investigated the effects of hypergravity and vibration on two‐dimensional adherent cells and three‐dimensional embedded cells and provided methods for storing hybrid bioink and high ...

Supersymmetric electric-magnetic duality of hypergravity
, 2014 Hypergravity is the theory in which the graviton, of spin-2, has a supersymmetric partner of spin-5/2. There are "no-go" theorems that prevent interactions in these higher spin theories.
