The uniqueness of hypergravity [PDF]
AbstractWe show that consistent interactions of a spin-2 and a higher-spin Majorana fermion gauge fields in 30 fiat space lead uniquely to Aragone-Deser hypergravity or its generalization. Our analysis employs the ERST-cohomological techniques, and works in the metric-like formulation under the assumptions of locality, parity and Poincaré invariance ...

Terrestrial plants respond to and resist gravitational force. The response is termed “gravity resistance”, and centrifugal hypergravity conditions are efficient for investigating its nature and mechanism.

Hypergravity down-regulates c-fos gene expression via ROCK/Rho-GTP and the PI3K signaling pathway in murine ATDC5 chondroprogenitor cells. [PDF]
Chondrocytes are known to be physiologically loaded with diverse physical factors such as compressive stress, shear stress and hydrostatic pressure. Although the effects of those mechanical stimuli onto various cell models have been widely studied, those

The effect of different gravity fields on mass transfer in the rat bone lacunar-canalicular system
The bone lacunar-canalicular system (LCS) is an important microscopic infrastructure for signaling and solute transport in bone tissue, which guarantees normal physiological processes of the tissue, but the mass transfer laws in the LCS under different ...

The Impact of Microgravity and Hypergravity on Endothelial Cells [PDF]
The endothelial cells (ECs), which line the inner surface of vessels, play a fundamental role in maintaining vascular integrity and tissue homeostasis, since they regulate local blood flow and other physiological processes. ECs are highly sensitive to mechanical stress, including hypergravity and microgravity.

Application of hypergravity in Eucalyptus and Corymbia seeds
: The aim of this study was to evaluate the growth responses of various Eucalyptus and Corymbia species subjected to different intensities of simulated hypergravity relative to the control. A centrifuge was used to simulate hypergravity. It was developed

Fault rupture propagation is more complex in the overlying soil with intercalation than in homogeneous soil, and it is challenging to simulate this phenomenon accurately using the finite element method.

An instrumented centrifuge for studying mouse locomotion and behaviour under hypergravity
Gravity may influence multiple aspects of legged locomotion, from the periods of limbs moving as pendulums to the muscle forces required to support the body.

Case Report: No Evidence of Intracranial Fluid Shifts in an Astronaut Following an Aborted Launch
Spaceflight induces lasting enlargement of the brain's ventricles as well as intracranial fluid shifts. These intracranial fluid shifts have been attributed to prolonged microgravity exposure, however, the potential effects of hypergravity exposure ...
