Another way of putting this is that phase flow topologies conserve a system's dynamic invariant features thus identifying all behavioral possibilities within a class in a model-independent manner.
Similarly angular momentum, which is related to spinning motions, is conserved in a system upon which no net turning force, called torque, acts.
Kenyon, C. A conserved regulatory system for aging.
It is possible that this may have involved bacterial Type IV secretion, a system conserved in Wolbachia.
Momentum is the product of mass and velocity, and the law of conservation of momentum dictates that the total momentum of a system is conserved, or remains constant.
The aim was not to have a system that conserves energy by compromising operational parameters, but a system that consumes less energy whilst maintaining coverage, handover probability and QoS.
A strategy to measure heterotypic antibodies to potentially protective antigens such as VP4 and VP7 in serum, that are not subject to the confounding effect of maternal IgG, is the measurement of IgA specific for either RV VP7 or VP4 proteins expressed in a system that conserves the neutralizing epitopes.
"You need a system to conserve the variety so it doesn't go extinct," Dr. Fowler said.
The trees may originally have spread because of the warmer climate, but the researchers suggest that there must have been a system for conserving them, and that they would have stabilized soil on the steep slopes.
Combining Newton's Second and Third Laws, it is possible to show that the linear momentum of a system is conserved.
The hypothalamus pituitary gonad (HPG) axis is one example of a system highly conserved across vertebrates (Norris 2007).
