Weightlessness and skeleton homeostasis
HORMONES, 2005 As human beings venture into space in the 21st century, they will be confronted with a "hypodynamic" and thus hostile environment for the bone homeostasis, that could potentially compromise their mobility in general and skeletal strength in particular after landing. From this point of view, space flight studies are especially interesting and intriguing

Weightless neural network parameters and architecture selection in a quantum computer [PDF]
Neurocomputing, Volume 183, 26 March 2016, Pages 13-22, 2016 Training artificial neural networks requires a tedious empirical evaluation to determine a suitable neural network architecture. To avoid this empirical process several techniques have been proposed to automatise the architecture selection process.

Spatial Updating Depends on Gravity
Frontiers in Neural Circuits, 2020 As we move through an environment the positions of surrounding objects relative to our body constantly change. Maintaining orientation requires spatial updating, the continuous monitoring of self-motion cues to update external locations.

Joint Cartilage in Long-Duration Spaceflight
Biomedicines, 2022 This review summarizes the current literature available on joint cartilage alterations in long-duration spaceflight. Evidence from spaceflight participants is currently limited to serum biomarker data in only a few astronauts.

The Mechanoreception in Drosophila melanogaster Oocyte under Modeling Micro- and Hypergravity
Cells, 2023 The hypothesis about the role of the cortical cytoskeleton as the primary mechanosensor was tested. Drosophila melanogaster oocytes were exposed to simulated microgravity (by 3D clinorotation in random directions with 4 rotations per minute—sµg group ...

Weightless Neural Network with Transfer Learning to Detect Distress in Asphalt [PDF]
International Journal of Advanced Engineering Research and
Science, Page No: 294-299, vol.5,no. 12, date:2018, 2019 The present paper shows a solution to the problem of automatic distress detection, more precisely the detection of holes in paved roads. To do so, the proposed solution uses a weightless neural network known as Wisard to decide whether an image of a road has any kind of cracks.

Mouse and Fly Sperm Motility Changes Differently under Modelling Microgravity
Current Issues in Molecular Biology, 2021 Sperm motility is essential for the natural fertilization process in most animal species. Despite the fact that evolution took place under conditions of constant gravity, the motility of spermatozoa of insects and mammals under microgravity conditions ...
