Computer Modeling Describes Gravity-Related Adaptation in Cell Cultures
Questions about the changes of biological systems in response to hostile environmental factors are important but not easy to answer. Often, the traditional description with differential equations is difficult due to the overwhelming complexity of the living systems. Another way to describe complex systems is by simulating them with phenomenological models such as the well-known evolutionary age...
متن کاملThe Perception of Upright under Lunar Gravity
Maintaining an upright posture on the moon is not easy. NASA documents abound with examples of astronauts falling on the moon during the visits between 1969 and 1972 (19,20). Even on the most recent moon visit (Apollo 17, 1972), Astronaut Harrison Schmidt fell over as he worked on the lunar surface.1 However, although regarded as highly desirable (7), few studies have investigated the perceptua...
متن کاملTests of Gravity Using Lunar Laser Ranging
Lunar laser ranging (LLR) has been a workhorse for testing general relativity over the past four decades. The three retroreflector arrays put on the Moon by the Apollo astronauts and the French built arrays on the Soviet Lunokhod rovers continue to be useful targets, and have provided the most stringent tests of the Strong Equivalence Principle and the time variation of Newton's gravitational c...
متن کاملConstraint on intermediate-range gravity from earth-satellite and lunar orbiter measurements, and lunar laser ranging
In the experimental tests of gravity, there have been considerable interests in the possibility of intermediate-range gravity. In this paper, we use the earth-satellite measurement of earth gravity, the lunar orbiter measurement of lunar gravity, and lunar laser ranging measurement to constrain the intermediate-range gravity from λ = 1.2×10m−3.8×10m. The limits for this range are α = 10−5×10, w...
متن کاملGRGM900C: A degree 900 lunar gravity model from GRAIL primary and extended mission data
We have derived a gravity field solution in spherical harmonics to degree and order 900, GRGM900C, from the tracking data of the Gravity Recovery and Interior Laboratory (GRAIL) Primary (1 March to 29 May 2012) and Extended Missions (30 August to 14 December 2012). A power law constraint of 3.6 ×10-4/ℓ2 was applied only for degree ℓ greater than 600. The model produces global correlations of gr...
