By adjusting their stubby wings, the 22 birds have controlled the streamer depth for the last month, holding it constant around nine 9 meters.
Subsequently, the researchers imposed 24-hour light/dark cycles, alternately advancing and retarding the clock giving the subjects a light regime that was later or earlier, respectively, than the actual time and then holding it constant.
For example, the value of β estimated from region 1, would be used for regions 1 and 2. The MESI curves from entire data set was then fit to Equation 1 using the estimated value of β, and holding it constant.
In contrast, arthritic rats that did not use their inflamed hindlimbs (see example in Figure 3A) did not show major movement in the knee joint, but held it at a rather constant angle of around 50° during the complete walking cycle, which cannot be divided into stance and swing phases in these animals, since there is no contact with the floor at any time.
Potassium is an essential electrolyte, and the body normally holds it at a constant level.
(Sample and hold is a circuit that samples the voltage of an analog device at any given moment and holds it at a constant value for a minimum amount of time).
If (3.6) holds (it holds when the related constants are small), then according to Theorem 3.1, the problem (4.1) has at least one mild solution in.
Many compatibilists about free will deny that this sort of ability to do otherwise is a requirement on freedom; even if they insist on there being some possibility of the agent's acting otherwise given some alternative possible set of desires, they do not hold that at the point of action, with all held constant, it must be possible for the agent to act otherwise.
Furthermore, when the environment is held constant, it is natural to seek steady state solutions to the equations.
